This is needed for situations where performance is sensitive. There are two goals with my implementation: 1. Don't create a copy of the value in the table. That's why I need the `cursor` pragma. Otherwise, it would copy the value 2. Don't double calculate the hash. That's kind of intrinsic with this implementation. But the only way to achieve this without this PR is to first check `if key in table` then to read `table[key]` I brought this up in the discord and a few folks tried to come up with options that were as fast as this, but nothing quite matched the performance here.

This PR is the first step towards overhauling hook injections. In this PR, hooks (except mAsgn) are treated consistently whether it is resolved in matching or instantiated by sempass2. It also fixes a spelling `=wasMoved` to its normalized version, which caused no replacing generic hook calls with lifted hook calls. --- compiler/injectdestructors.nim | 6 +- compiler/liftdestructors.nim | 29 +++--- compiler/semcall.nim | 8 -- compiler/semdata.nim | 165 ++++++++++++++++++++++++++++++++- compiler/semexprs.nim | 100 -------------------- compiler/semmagic.nim | 37 +------- compiler/sempass2.nim | 39 +++++--- lib/pure/streamwrapper.nim | 3 +- lib/system.nim | 4 +- 9 files changed, 213 insertions(+), 178 deletions(-) diff --git a/compiler/injectdestructors.nim b/compiler/injectdestructors.nim index 90c83124b1..932851a3ca 100644 --- a/compiler/injectdestructors.nim +++ b/compiler/injectdestructors.nim @@ -17,14 +17,14 @@ import ast, astalgo, msgs, renderer, magicsys, types, idents, options, lowerings, modulegraphs, lineinfos, parampatterns, sighashes, liftdestructors, optimizer, -

However `propertyWriteAccess` never returned nil, because `semOverloadedCallAnalyseEffects` was not called with `efNoUndeclared` and so produced an error directly. So `efNoUndeclared` is passed to this call so this code works as intended. This fixes the issue described in #4711 which was closed because subscripts do not have the same behavior implemented. However we can implement this for subscripts as well (I have an implementation ready), it just changes the error message from the failed overloads of `[]=` to the failed overloads of `[]` for the LHS, which might be misleading but is consistent with the error messages for any other assignment. I can do this in this PR or another one. --- compiler/semexprs.nim | 2 +- tests/specialops/terrmsgs.nim | 3 +-- tests/specialops/tmismatch.nim | 2 +- tests/specialops/tsetterfallback1.nim | 24 ++++++++++++++++++++++++ tests/specialops/tsetterfallback2.nim | 8 ++++++++ 5 files changed, 35 insertions(+), 4 deletions(-) create mode 100644 tests/specialops/tsetterfallback1.nim create mode 100644 tests/specialops/tsetterfallback2.nim diff --git a/compiler/semexprs.nim b/compiler/semexprs.nim index 1dc952be51..55a58c7f04 100644 --- a/compiler/semexprs.nim +++ b/compiler/semexprs.nim @@ -1787,7 +1787,7 @@ proc propertyWriteAccess(c: PContext, n, nOrig, a: PNode): PNode = result = newTreeI(nkCall, n.info, setterId, a[0], n[1]) result.flags.incl nfDotSetter let orig = newTreeI(nkCall, n.info, setterId, aOrig[0], nOrig[1]) - result = semOverloadedCallAnalyseEffects(c, result, orig, {}) + result = semOverloadedCallAnalyseEffects(c, result, orig, {efNoUndeclared}) if result != nil: result = afterCallActions(c, result, nOrig, {}) diff --git a/tests/specialops/terrmsgs.nim b/tests/specialops/terrmsgs.nim index 081bca4510..534c0c4543 100644 --- a/tests/specialops/terrmsgs.nim +++ b/tests/specialops/terrmsgs.nim @@ -26,8 +26,7 @@ block: block: template `.=`(a: Foo, b: untyped, c: untyped) = b = c b.x = 123 #[tt.Error - ^ undeclared field: 'x=' for type terrmsgs.Bar [type declared in terrmsgs.nim(15, 8)]]# - # yeah it says x= but does it matter in practice + ^ undeclared field: 'x' for type terrmsgs.Bar [type declared in terrmsgs.nim(15, 8)]]# block: template `()`(a: Foo, b: untyped, c: untyped) = echo "something" diff --git a/tests/specialops/tmismatch.nim b/tests/specialops/tmismatch.nim index 76c921b14a..7d0a4229dc 100644 --- a/tests/specialops/tmismatch.nim +++ b/tests/specialops/tmismatch.nim @@ -14,4 +14,4 @@ template `.=`*(flags: Flags, key: Flag, val: bool) = var flags: Flags flags.A = 123 #[tt.Error - ^ undeclared field: 'A=' for type tmismatch.Flags [type declared in tmismatch.nim(9, 5)]]# + ^ undeclared field: 'A' for type tmismatch.Flags [type declared in tmismatch.nim(9, 5)]]# diff --git a/tests/specialops/tsetterfallback1.nim b/tests/specialops/tsetterfallback1.nim new file mode 100644 index 0000000000..6a0b1104e3 --- /dev/null +++ b/tests/specialops/tsetterfallback1.nim @@ -0,0 +1,24 @@ +# issue #4711 + +type + Vec4 = object + x,y,z,w : float32 + + Vec3 = object + x,y,z : float32 + +proc `+=`(v0: var Vec3; v1: Vec3) = + v0.x += v1.x + v0.y += v1.y + v0.z += v1.z + +proc xyz(v: var Vec4): var Vec3 = + cast[ptr Vec3](v.x.addr)[] + +let tmp = Vec3(x: 1, y:2, z:3) +var dst = Vec4(x: 4, y:4, z:4, w:4) + +xyz(dst) = tmp # works +dst.xyz() = tmp # works +dst.xyz += tmp # works +dst.xyz = tmp # attempting to call undeclared routine `xyz=` diff --git a/tests/specialops/tsetterfallback2.nim b/tests/specialops/tsetterfallback2.nim new file mode 100644 index 0000000000..8458b2dc8b --- /dev/null +++ b/tests/specialops/tsetterfallback2.nim @@ -0,0 +1,8 @@ +# https://forum.nim-lang.org/t/12785 + +proc x(pt: var array[2, float]): var float = pt[0] + +var pt = [0.0, 0.0] +pt.x += 1.0 # <-- fine +x(pt) = 1.0 # <-- fine +pt.x = 1.0 # <-- does not compile From c06bb6cc03f1a42d515949967c0c9f267e971d04 Mon Sep 17 00:00:00 2001 From: metagn Date: Tue, 15 Apr 2025 20:29:46 +0300 Subject: [PATCH 045/448] don't traverse inner procs to lift locals in closure iters (#24876) fixes #24863, refs #23787 and #24316 Working off the minimized example, my understanding of the issue is: `n` captures `r` as `:envP.r1` where `:envP` is the environment of `b`, then `proc () = n()` does the lambda lifting of `n` again (which isn't done if the `proc ()` is marked `{.closure.}`, hence the workaround) which then captures the `:envP` as another field inside the `:envP`, so it generates `:envP.:envP_2.r1` but the `.:envP_2` field is `nil`, so it causes a segfault. The problem is that the capture of `r` in `n` is done inside `detectCapturedVars` for the surrounding closure iterator: inner procs are not special cased and traversed as regular nodes, so it thinks it's inside the iterator and generates a field access of `:envP` freely. The lambda lifting version of `detectCapturedVars` ignores inner procs and works off of symbol uses (anonymous iterator and lambda declarations pretend their symbol is used). As a naive solution, closure iterators now also ignore inner proc declarations same as `lambdalifting.detectCapturedVars`, but unlike it they also don't do anything for the inner proc symbols. Lambdalifting seems to properly handle the lifted variables but in the worst case we can also make sure `closureiters.detectCapturedVars` traverses inner procs by marking every local of the closure iter used in them as needing lifting (but not doing the lifting). This does not seem necessary for now so it's not done (was done and reverted in [this commit](https://github.com/nim-lang/Nim/pull/24876/commits/9bb39a9259ecf7d93c64a096138f8a2d108333d5)), but regressions are still possible --- compiler/closureiters.nim | 14 ++++++++++++++ compiler/lambdalifting.nim | 2 +- tests/iter/t24863.nim | 30 ++++++++++++++++++++++++++++++ tests/iter/tnestedclosures.nim | 20 ++++++++++++++++++++ 4 files changed, 65 insertions(+), 1 deletion(-) create mode 100644 tests/iter/t24863.nim diff --git a/compiler/closureiters.nim b/compiler/closureiters.nim index 7e0f54b12e..835cbf0ca7 100644 --- a/compiler/closureiters.nim +++ b/compiler/closureiters.nim @@ -1451,6 +1451,14 @@ proc detectCapturedVars(c: var Ctx, n: PNode, stateIdx: int) = detectCapturedVars(c, n[0][1], stateIdx) else: detectCapturedVars(c, n[0], stateIdx) + of nkEmpty..pred(nkSym), succ(nkSym)..nkNilLit, + nkTemplateDef, nkTypeSection, nkProcDef, nkMethodDef, + nkConverterDef, nkMacroDef, nkFuncDef, nkCommentStmt, + nkTypeOfExpr, nkMixinStmt, nkBindStmt: + discard + of nkLambdaKinds, nkIteratorDef: + if n.typ != nil: + detectCapturedVars(c, n[namePos], stateIdx) else: for i in 0 ..< n.safeLen: detectCapturedVars(c, n[i], stateIdx) @@ -1481,6 +1489,12 @@ proc liftLocals(c: var Ctx, n: PNode): PNode = n[0][1] = liftLocals(c, n[0][1]) else: n[0] = liftLocals(c, n[0]) + of nkEmpty..pred(nkSym), succ(nkSym)..nkNilLit, + nkTemplateDef, nkTypeSection, nkProcDef, nkMethodDef, + nkConverterDef, nkMacroDef, nkFuncDef, nkCommentStmt, + nkTypeOfExpr, nkMixinStmt, nkBindStmt, + nkLambdaKinds, nkIteratorDef: + discard else: for i in 0 ..< n.safeLen: n[i] = liftLocals(c, n[i]) diff --git a/compiler/lambdalifting.nim b/compiler/lambdalifting.nim index 640bb4b2f8..c8c5acf974 100644 --- a/compiler/lambdalifting.nim +++ b/compiler/lambdalifting.nim @@ -199,7 +199,7 @@ proc interestingVar(s: PSym): bool {.inline.} = proc illegalCapture(s: PSym): bool {.inline.} = result = classifyViewType(s.typ) != noView or s.kind == skResult -proc isInnerProc(s: PSym): bool = +proc isInnerProc*(s: PSym): bool = if s.kind in {skProc, skFunc, skMethod, skConverter, skIterator} and s.magic == mNone: result = s.skipGenericOwner.kind in routineKinds else: diff --git a/tests/iter/t24863.nim b/tests/iter/t24863.nim new file mode 100644 index 0000000000..96ddbcef7c --- /dev/null +++ b/tests/iter/t24863.nim @@ -0,0 +1,30 @@ +# issue #24863 + +type M = object + p: iterator(): M {.gcsafe.} + +template h(f: M): int = + yield f + 456 + +proc s(): M = + iterator g(): M {.closure.} = discard + let v = M(p: g) + doAssert(not isNil(v.p)) + discard v.p() + v + +proc c(): M = + iterator b(): M {.closure.} = + let r = h(s()) + doAssert r == 456 + proc n(): M = + iterator y(): M {.closure.} = + let _ = r + let _ = y + let _ = proc () = discard n() + let j = M(p: b) + doAssert(not isNil(j.p)) + discard j.p() + +let _ = c() diff --git a/tests/iter/tnestedclosures.nim b/tests/iter/tnestedclosures.nim index e23fa1355f..f2dc7a51d4 100644 --- a/tests/iter/tnestedclosures.nim +++ b/tests/iter/tnestedclosures.nim @@ -25,6 +25,9 @@ Test 7: 0 1 2 +Test 8: +123 +456 ''' """ @@ -156,3 +159,20 @@ block: # issue #12487 doAssert s == @["something"] main() + +block: # minimized issue #24863 + echo "Test 8:" + proc c() = + iterator b(): int {.closure.} = + let r = 456 + yield 123 + proc n() = + echo r + let a = proc () = n() + a() + + let j = b + echo j() + discard j() + + c() From e7f73bfebee41c597f5e37b5e635e413944324b7 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Juan=20M=20G=C3=B3mez?= Date: Wed, 16 Apr 2025 11:11:33 +0100 Subject: [PATCH 046/448] Fixes a nimsuggest crash (#24873) --- compiler/vmgen.nim | 4 ++++ 1 file changed, 4 insertions(+) diff --git a/compiler/vmgen.nim b/compiler/vmgen.nim index 4afe01a7e3..e8612000a3 100644 --- a/compiler/vmgen.nim +++ b/compiler/vmgen.nim @@ -1885,6 +1885,10 @@ proc genCheckedObjAccess(c: PCtx;

Now the `;` token is skipped and the indentation of the first `discard` is used which is > -1. However the second discard has an indentation of -1 because it's on the same line: this fails the `sameInd(p) or realInd(p)` check since -1 is never >= the indent of the first discard. For compatibility with the parser up to this point this indent check is entirely removed, meaning the indent is ignored. Because the `;` is basically never on a separate line, this was already the case for basically every use. `semiStmtList` is wrapped in a `withInd` anyway which resets the indent after it's done, since the entire statement list is wrapped in a `()`. To disallow dedents, the above check could be fixed to use `sameOrNoInd` instead of `sameInd`, which is done in the commented version of this check. --- compiler/parser.nim | 5 +++-- tests/parser/tstmtlistexprindent.nim | 7 +++++++ 2 files changed, 10 insertions(+), 2 deletions(-) create mode 100644 tests/parser/tstmtlistexprindent.nim diff --git a/compiler/parser.nim b/compiler/parser.nim index 7f438f4208..03c3ac2648 100644 --- a/compiler/parser.nim +++ b/compiler/parser.nim @@ -638,8 +638,9 @@ proc semiStmtList(p: var Parser, result: PNode) = getTok(p) if p.tok.tokType == tkParRi: break - elif not (sameInd(p) or realInd(p)): - parMessage(p, errInvalidIndentation) + # ignore indent: + #elif not (sameOrNoInd(p) or realInd(p)): + # parMessage(p, errInvalidIndentation) let a = complexOrSimpleStmt(p) if a.kind == nkEmpty: parMessage(p, errExprExpected, p.tok) diff --git a/tests/parser/tstmtlistexprindent.nim b/tests/parser/tstmtlistexprindent.nim new file mode 100644 index 0000000000..5c6c25151c --- /dev/null +++ b/tests/parser/tstmtlistexprindent.nim @@ -0,0 +1,7 @@ +type E = enum A, B, C +proc junk(e: E) = + case e + of A: (echo "a"; + discard; discard; + discard) + else: discard From af9219ada72078c4cbc294168374a373d2b3c8e3 Mon Sep 17 00:00:00 2001 From: ringabout <43030857+ringabout@users.noreply.github.com> Date: Fri, 18 Apr 2025 00:04:03 +0800 Subject: [PATCH 051/448] fixes #24881; build_all.sh koch tools fails to build atlas (#24884) fixes #24881 To test: `nim c koch.nim` + delete the `dist` directory --- koch.nim | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/koch.nim b/koch.nim index 9d15ff18bd..0703ea61b0 100644 --- a/koch.nim +++ b/koch.nim @@ -12,7 +12,7 @@ const # examples of possible values for repos: Head, ea82b54 NimbleStableCommit = "b1dc28450f028aead0b7cf5da8adf2267db65f89" # 0.18.2 - AtlasStableCommit = "dd9961b1f8da8d1e8759860bc24c1bf3b1df423e" # 0.9 + AtlasStableCommit = "26cecf4d0cc038d5422fc1aa737eec9c8803a82b" # 0.9 ChecksumsStableCommit = "f8f6bd34bfa3fe12c64b919059ad856a96efcba0" # 2.0.1 SatStableCommit = "faf1617f44d7632ee9601ebc13887644925dcc01" From 5aaba213d426e67a0761c6dcb7a37d8663026d92 Mon Sep 17 00:00:00 2001 From: metagn Date: Fri, 18 Apr 2025 06:32:49 +0300 Subject: [PATCH 052/448] account for invalid data in enum `$` on arc/orc (#24886) closes #24875 Refc gives `0 (invalid data!)`, but since enum `$` procs on arc are generated during enum declarations we might not have access to string concatenation and integer `$`, so it generates a static string.

If the existing type of the symbol is an enum and and the RHS has a nominal enum type node, the enum fields of the existing type are added to scope rather than creating a new type from the RHS and adding its symbols instead. The goal is to prevent any incompatible nominal types from being generated during resem as in #24887. But it also restricts what macros can do if they generate type section AST, for example if we have: ```nim type Foo = int ``` and a macro modifies the type section while keeping the symbol node for `Foo` like: ```nim type Foo = float ``` Then the type of `Foo` will still remain `int`, while it previously became `float`. While we could maybe allow this and make it so only nominal types cannot be changed, it gets even more complex when considering generic params and whether or not they get updated. So to keep it as simple as possible the rule is that the symbol type does not change, but maybe this behavior was useful for macros. Only nominal type nodes are ignored for semchecking on the RHS, so that cases like this do not cause a regression: ```nim template foo(): untyped = proc bar() {.inject.} = discard int type Foo = foo() bar() # normally works ``` However this specific code exposed a problem with forward type handling: --- In specific cases, when the type section is undergoing the final pass, if the type fits some overly general criteria (it is not an object, enum, alias or a sink type and its node is not a nominal type node), the entire RHS is semchecked for a 2nd time as a standalone type (with `nil` prev) and *maybe* reassigned to the new semchecked type, depending on its type kind. (for some reason including nominal types when we excluded them before?) This causes a redefinition error if the RHS defines a symbol. This code goes all the way back to the first commit and I could not find the reason why it was there, but removing it showed a failure in `thard_tyforward`: If a generic forward type is invoked, it is left as an unresolved `tyGenericInvocation` on the first run. Semchecking it again at the end turns it into a `tyGenericInst`. So my understanding is that it exists to handle these loose forward types, but it is way too general and there is a similar mechanism `c.skipTypes` which is supposed to do the same thing but doesn't. So this is no longer done, and `c.skipTypes` is revamped (and renamed): It is now a list of types and the nodes that are supposed to evaluate to them, such that types needing to be updated later due to containing forward types are added to it along with their nodes. When finishing the type section, these types are reassigned to the semchecked value of their nodes so that the forward types in them are fully resolved. The "reassigning" here works due to updating the data inside the type pointer directly, and is how forward types work by themselves normally (`tyForward` types are modified in place as `s.typ`). For example, as mentioned before, generic invocations of forward types are first created as `tyGenericInvocation` and need to become `tyGenericInst` later. So they are now added to this list along with their node. Object types with forward types as their base types also need to be updated later to check that the base type is correct/inherit fields from it: For this the entire object type and its node are added to the list. Similarly, any case where whether a component type is `tyGenericInst` or `tyGenericInvocation` matters also needs to cascade this (`set` does presumably to check the instantiated type). This is not complete: Generic invocations with forward types only check that their base type is a forward type, but not any of their arguments, which causes #16754 and #24133. The generated invocations also need to cascade properly: `Foo[Bar[ForwardType]]` for example would see that `Bar[ForwardType]` is a generic invocation and stay as a generic invocation itself, but it might not queue itself to be updated later. Even if it did, only the entire type `Foo[Bar[ForwardType]]` needs to be queued, updating `Bar[ForwardType]` by itself would be redundant or it would not change anything at all. But these can be done later. --- compiler/semdata.nim | 4 +- compiler/semstmts.nim | 72 +++++++++++++++++----------- compiler/semtypes.nim | 41 ++++++++++++++-- compiler/types.nim | 2 +- nimsuggest/tests/ttype_highlight.nim | 4 -- tests/types/tresemtypesection.nim | 55 +++++++++++++++++++++ 6 files changed, 141 insertions(+), 37 deletions(-) create mode 100644 tests/types/tresemtypesection.nim diff --git a/compiler/semdata.nim b/compiler/semdata.nim index 5eb8086f45..fa697f90cd 100644 --- a/compiler/semdata.nim +++ b/compiler/semdata.nim @@ -172,7 +172,9 @@ type sideEffects*: Table[int, seq[(TLineInfo, PSym)]] # symbol.id index inUncheckedAssignSection*: int importModuleLookup*: Table[int, seq[int]] # (module.ident.id, [module.id]) - skipTypes*: seq[PNode] # used to skip types between passes in type section.

Date: Mon, 21 Apr 2025 10:01:44 +0300 Subject: [PATCH 057/448] generally disallow recursive structural types, check proc param types (#24893) fixes #5631, fixes #8938, fixes #18855, fixes #19271, fixes #23885, fixes #24877 `isTupleRecursive`, previously only called to give an error for illegal recursions for: * tuple fields * types declared in type sections * explicitly instantiated generic types did not check for recursions in proc types. It now does, meaning proc types now need a nominal type layer to recurse over themselves. It is renamed to `isRecursiveStructuralType` to better reflect what it does, it is different from a recursive type that cannot exist due to a lack of pointer indirection which is possible for nominal types. It is now also called to check the param/return types of procs, similar to how tuple field types are checked. Pointer indirection checks are not needed since procs are pointers. I wondered if this would lead to a slowdown in the compiler but since it only skips structural types it shouldn't take too many iterations, not to mention only proc types are newly considered and aren't that common. But maybe something in the implementation could be inefficient, like the cycle detector using an IntSet. Note: The name `isRecursiveStructuralType` is not exactly correct because it still checks for `distinct` types. If it didn't, then the compiler would accept this: ```nim type A = distinct B B = ref A ``` But this breaks when attempting to write `var x: A`. However this is not the case for: ```nim type A = object x: B B = ref A ``` So a better description would be "types that are structural on the backend". A future step to deal with #14015 and #23224 might be to check the arguments of `tyGenericInst` as well but I don't know if this makes perfect sense. --- compiler/seminst.nim | 4 +++ compiler/semtypes.nim | 10 ++++-- compiler/semtypinst.nim | 2 +- compiler/types.nim | 23 +++++++++---- tests/errmsgs/trecursiveproctype1.nim | 10 ++++++ tests/errmsgs/trecursiveproctype2.nim | 18 ++++++++++ tests/errmsgs/trecursiveproctype3.nim | 9 +++++ tests/errmsgs/trecursiveproctype4.nim | 10 ++++++ tests/errmsgs/trecursiveproctype5.nim | 49 +++++++++++++++++++++++++++ tests/errmsgs/trecursiveproctype6.nim | 10 ++++++ 10 files changed, 135 insertions(+), 10 deletions(-) create mode 100644 tests/errmsgs/trecursiveproctype1.nim create mode 100644 tests/errmsgs/trecursiveproctype2.nim create mode 100644 tests/errmsgs/trecursiveproctype3.nim create mode 100644 tests/errmsgs/trecursiveproctype4.nim create mode 100644 tests/errmsgs/trecursiveproctype5.nim create mode 100644 tests/errmsgs/trecursiveproctype6.nim diff --git a/compiler/seminst.nim b/compiler/seminst.nim index ab00810f92..c23e3f80d8 100644 --- a/compiler/seminst.nim +++ b/compiler/seminst.nim @@ -308,6 +308,8 @@ proc instantiateProcType(c: PContext, pt: LayeredIdTable, param.typ = result[i] result.n[i] = newSymNode(param) + if isRecursiveStructuralType(result[i]): + localError(c.config, originalParams[i].sym.info, "illegal recursion in type '" & typeToString(result[i]) & "'") propagateToOwner(result, result[i]) addDecl(c, param) @@ -318,6 +320,8 @@ proc instantiateProcType(c: PContext, pt: LayeredIdTable, cl.isReturnType = false result.n[0] = originalParams[0].copyTree if result[0] != nil: + if isRecursiveStructuralType(result[0]): + localError(c.config, originalParams[0].info, "illegal recursion in type '" & typeToString(result[0]) & "'") propagateToOwner(result, result[0]) eraseVoidParams(result) diff --git a/compiler/semtypes.nim b/compiler/semtypes.nim index 41189fc7f8..9ebc930079 100644 --- a/compiler/semtypes.nim +++ b/compiler/semtypes.nim @@ -576,7 +576,7 @@ proc semTuple(c: PContext, n: PNode, prev: PType): PType = styleCheckDef(c, a[j].info, field) onDef(field.info, field) if result.n.len == 0: result.n = nil -

by simply (#24945) explaining why the result may not be so surprising. Clean-up of stray whitespace and insert of missing "in" along for the ride. It's just not always faster or slower than `Table`. The difference depends upon many factors such as (at least!): A) how much (if anything - for `int` keys it is nothing) hash-comparison before `==` comparison saves B) how much resizing happens (which may even vary from run to run if end users are allowed to provide scale guess input), C) how much comparison happens at all (i.e., table density), D) how much space/size matters - like how close to a specific deployment "available" cache size the table is. If we want, we could add a sentence suggesting performance fans also try `Table`, but the kind of low-level nature of the explanation strikes me as already along those lines. --- lib/pure/collections/tables.nim | 16 ++++------------ 1 file changed, 4 insertions(+), 12 deletions(-) diff --git a/lib/pure/collections/tables.nim b/lib/pure/collections/tables.nim index 9a71a28d50..92f85b1464 100644 --- a/lib/pure/collections/tables.nim +++ b/lib/pure/collections/tables.nim @@ -107,7 +107,7 @@ runnableExamples: ## container (e.g. string, sequence or array), as it is a mapping where the ## items are the keys, and their number of occurrences are the values. ## For that purpose `toCountTable proc<#toCountTable,openArray[A]>`_ -## comes handy: +## comes in handy: runnableExamples: let myString = "abracadabra" @@ -2329,19 +2329,15 @@ iterator mvalues*[A, B](t: OrderedTableRef[A, B]): var B = yield t.data[h].val assert(len(t) == L, "the length of the table changed while iterating over it") - - - - - - # ------------------------------------------------------------------------- # ------------------------------ CountTable ------------------------------- # ------------------------------------------------------------------------- type CountTable*[A] = object - ## Hash table that counts the number of each key. + ## Hash table that counts the number of each key.

However the reason it does not generate a destructor is that it expects it to be fully unpacked, this is true for unpackings in for loops but not for tuple unpacking assignments which supports `_` since #22537. Tuple unpacking definitions for `var`/`let`/`const` do not generate `skTemp` and use the same symbol kind as the definition so they did not have this problem. To keep this compatible, the `_` parts of the tuple unpacking assignments are now not ignored and unpacked into `let _ = ...`, which generates its own destructor. Another option might be to use `skLet` instead of `skTemp` but this might cause changes to behavior like additional copies, I am not sure about this though. --- compiler/injectdestructors.nim | 9 +++++---- compiler/semexprs.nim | 16 ++++++++++++++-- tests/arc/tpartialtupleunpacking1.nim | 19 +++++++++++++++++++ tests/arc/tpartialtupleunpacking2.nim | 18 ++++++++++++++++++ 4 files changed, 56 insertions(+), 6 deletions(-) create mode 100644 tests/arc/tpartialtupleunpacking1.nim create mode 100644 tests/arc/tpartialtupleunpacking2.nim diff --git a/compiler/injectdestructors.nim b/compiler/injectdestructors.nim index cacb3305eb..fcbe89df5c 100644 --- a/compiler/injectdestructors.nim +++ b/compiler/injectdestructors.nim @@ -185,10 +185,11 @@ proc isCursor(n: PNode): bool = else: false -template isUnpackedTuple(n: PNode): bool = +template isFullyUnpackedTuple(n: PNode): bool = ## we move out all elements of unpacked tuples, ## hence unpacked tuples themselves don't need to be destroyed ## except it's already a cursor + ## restricted to `skTemp`, tuple temps where not every field is unpacked should not use `skTemp` (n.kind == nkSym and n.sym.kind == skTemp and n.sym.typ.kind == tyTuple and sfCursor notin n.sym.flags) @@ -275,7 +276,7 @@ proc deepAliases(dest, ri: PNode): bool = return aliases(dest, ri) != no proc genSink(c: var Con; s: var Scope; dest, ri: PNode; flags: set[MoveOrCopyFlag] = {}): PNode = - if (c.inLoopCond == 0 and (isUnpackedTuple(dest) or IsDecl in flags or + if (c.inLoopCond == 0 and (isFullyUnpackedTuple(dest) or IsDecl in flags or (isAnalysableFieldAccess(dest, c.owner) and isFirstWrite(dest, c)))) or isNoInit(dest) or IsReturn in flags: # optimize sink call into a bitwise memcopy @@ -559,7 +560,7 @@ proc cycleCheck(n: PNode; c: var Con) = proc pVarTopLevel(v: PNode; c: var Con; s: var Scope; res: PNode) = # move the variable declaration to the top of the frame: s.vars.add v.sym - if isUnpackedTuple(v): + if isFullyUnpackedTuple(v): if c.inLoop > 0: # unpacked tuple needs reset at every loop iteration res.add newTree(nkFastAsgn, v, genDefaultCall(v.typ, c, v.info)) @@ -1148,7 +1149,7 @@ proc moveOrCopy(dest, ri: PNode; c: var Con; s: var Scope, flags: set[MoveOrCopy of nkCallKinds: result = c.genSink(s, dest, p(ri, c, s, consumed), flags) of nkBracketExpr: - if isUnpackedTuple(ri[0]): + if isFullyUnpackedTuple(ri[0]): # unpacking of tuple: take over the elements result = c.genSink(s, dest, p(ri, c, s, consumed), flags) elif isAnalysableFieldAccess(ri, c.owner) and isLastRead(ri, c, s): diff --git a/compiler/semexprs.nim b/compiler/semexprs.nim index 2a3a4d13d4..5e2a5d0a72 100644 --- a/compiler/semexprs.nim +++ b/compiler/semexprs.nim @@ -1923,8 +1923,20 @@ proc makeTupleAssignments(c: PContext; n: PNode): PNode = for i in 0..

This is accomplished by just compiling the LHS if the assignment overloads fail. This has the side effect that the error messages are different now, instead of displaying the overloads of `[]=`/`{}=` that did not match, it will display the ones for `[]`/`{}` instead. This could be fixed by checking for `efLValue` when giving the error messages for `[]`/`{}` but this is not done here. The code for `[]` subscripts is a little different because of the `mArrGet`/`mArrPut` overloads that always match. If the `mArrPut` overload matches without a builtin subscript behavior for the LHS then it calls `semAsgn` again with `mode = noOverloadedSubscript`. Before this meant "fail to compile" but now it means "try to compile the LHS as normal", in both cases the overloads of `[]=` are not considered again. --- compiler/semexprs.nim | 23 +++++-- tests/errmsgs/t22753.nim | 65 ++++++++++--------- tests/specialops/tsetterfallbacksubscript.nim | 25 +++++++ 3 files changed, 79 insertions(+), 34 deletions(-) create mode 100644 tests/specialops/tsetterfallbacksubscript.nim diff --git a/compiler/semexprs.nim b/compiler/semexprs.nim index 5e2a5d0a72..6cc29bd86f 100644 --- a/compiler/semexprs.nim +++ b/compiler/semexprs.nim @@ -1963,21 +1963,34 @@ proc semAsgn(c: PContext, n: PNode;

I am not exactly sure how but at some point typed generics causes an `nfDotField` call to contain a symchoice for the field name. The compiler does not use the fact that the field name is an identifier, so the assert is loosened to allow any identifier-like node kind. Could also investigate why the symchoice gets created, my guess is that typed generics detects that the match fails but still sends it through generic prechecking and doesn't remove the `nfDotField`, which is harmless and it might cause more trouble to work around it. --- compiler/semcall.nim | 2 +- tests/generics/twrongdotcallcrash.nim | 6 ++++++ 2 files changed, 7 insertions(+), 1 deletion(-) create mode 100644 tests/generics/twrongdotcallcrash.nim diff --git a/compiler/semcall.nim b/compiler/semcall.nim index 866ddbe68f..038d7b0131 100644 --- a/compiler/semcall.nim +++ b/compiler/semcall.nim @@ -581,7 +581,7 @@ proc resolveOverloads(c: PContext, n, orig: PNode, let overloadsState = result.state if overloadsState != csMatch: if nfDotField in n.flags: - internalAssert c.config, f.kind == nkIdent and n.len >= 2 + internalAssert c.config, f.kind in nkIdentKinds and n.len >= 2 # leave the op head symbol empty, # we are going to try multiple variants diff --git a/tests/generics/twrongdotcallcrash.nim b/tests/generics/twrongdotcallcrash.nim new file mode 100644 index 0000000000..b4f1b1d9f5 --- /dev/null +++ b/tests/generics/twrongdotcallcrash.nim @@ -0,0 +1,6 @@ +# issue #25000 + +proc r(T: typedesc[int]): int = discard +proc c[J: typedesc[uint]](u = J.r) = discard #[tt.Error + ^ undeclared field: 'r']# +c[uint]() From c22bfe6bc06951a037d3094612151c6ea1b9fc79 Mon Sep 17 00:00:00 2001 From: ringabout <43030857+ringabout@users.noreply.github.com> Date: Tue, 17 Jun 2025 03:50:06 +0800 Subject: [PATCH 105/448] fixes #24996; Crash on marking destroy hook as .error (#25002) fixes #24996 uses the lineinfos of `dest` is `ri` is not available (e.g. `=destroy` doesn't have a second parameter) --- compiler/injectdestructors.nim | 10 ++++++++-- tests/errmsgs/t24996.nim | 14 ++++++++++++++ 2 files changed, 22 insertions(+), 2 deletions(-) create mode 100644 tests/errmsgs/t24996.nim diff --git a/compiler/injectdestructors.nim b/compiler/injectdestructors.nim index 39e8defe6d..f57d451c06 100644 --- a/compiler/injectdestructors.nim +++ b/compiler/injectdestructors.nim @@ -198,7 +198,8 @@ proc checkForErrorPragma(c: Con; t: PType; ri: PNode; opname: string; inferredFr if inferredFromCopy: m.add ", which is inferred from unavailable '=copy'" - if (opname == "=" or opname == "=copy" or opname == "=dup") and ri != nil: + if (opname == "=" or opname == "=copy" or opname == "=dup") and + ri != nil: m.add "; requires a copy because it's not the last read of '" m.add renderTree(ri) m.add '\'' @@ -248,7 +249,12 @@ proc genOp(c: var Con; t: PType; kind: TTypeAttachedOp; dest, ri: PNode): PNode dbg: if kind == attachedDestructor: echo "destructor is ", op.id, " ", op.ast - if sfError in op.flags: checkForErrorPragma(c, t, ri, AttachedOpToStr[kind]) + if sfError in op.flags: + if ri != nil: + checkForErrorPragma(c, t, ri, AttachedOpToStr[kind]) + else: + # uses the lineinfos of `dest` is `ri` is not available + checkForErrorPragma(c, t, dest, AttachedOpToStr[kind]) c.genOp(op, dest) proc genDestroy(c: var Con; dest: PNode): PNode = diff --git a/tests/errmsgs/t24996.nim b/tests/errmsgs/t24996.nim new file mode 100644 index 0000000000..e831b8c732 --- /dev/null +++ b/tests/errmsgs/t24996.nim @@ -0,0 +1,14 @@ +discard """ + errormsg: "'=destroy' is not available for type ; routine: main" + joinable: false +""" + +type X = object + +proc `=destroy`(x: X) {.error.} = + discard + +proc main() = + var x = X() + +main() \ No newline at end of file From aba93615105b8243b95c534f2d7c39aa69ace997 Mon Sep 17 00:00:00 2001 From: Jacek Sieka Date: Wed, 18 Jun 2025 14:38:01 +0200 Subject: [PATCH 106/448] Ensure that gc interface remains non-raising (#25006) GC_fullCollect in particular has an annoying `Exception` effect --- lib/system/arc.nim | 4 ++++ lib/system/cyclebreaker.nim | 4 ++-- lib/system/gc.nim | 2 ++ lib/system/gc_interface.nim | 20 ++++++++++---------- lib/system/orc.nim | 8 ++++++-- 5 files changed, 24 insertions(+), 14 deletions(-) diff --git a/lib/system/arc.nim b/lib/system/arc.nim index d67af9817a..adf1d833a1 100644 --- a/lib/system/arc.nim +++ b/lib/system/arc.nim @@ -14,6 +14,8 @@ at offset 0 then.

At this point any extra states or jumps should be considered a bug. The resulting codegen (compiled binaries) is also slightly smaller. **BUT:** - I had to change C++ reraising logic, see expt.nim. Because with closure iters `currentException` is not always in sync with C++'s notion of current exception. From my tests and understanding of C++ runtime there should not be any problems, but I'm only 99% sure :) - I've reused `nfNoRewrite` flag in one specific case during the transformation. This flag is also used in term-rewriting logic.

Previously, the example on line 4065 of `doc/manual.md` used variables `a`, `b`, and `c`: ```nim assert `*+`(3, 4, 6) == `+`(`*`(a, b), c) ``` This did not match the preceding call which directly used literals `3`, `4`, `6`. Updated the example to: ```nim assert `*+`(3, 4, 6) == `+`(`*`(3, 4), 6) ``` This change makes the example consistent with the function call and immediately understandable to readers without requiring prior variable definitions. ## Rationale * Improves clarity by avoiding undefined variables in a code snippet. * Matches the example usage in the preceding line. * Helps beginners understand the operator's behavior without additional context. ## Changes * **Edited**: `doc/manual.md` line 4065 — replaced variables `a`, `b`, `c` with literals `3`, `4`, `6`. ## Issue Closes #25084 --- doc/manual.md | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/doc/manual.md b/doc/manual.md index 9abd0e762c..29006a7536 100644 --- a/doc/manual.md +++ b/doc/manual.md @@ -4062,7 +4062,7 @@ notation.

It is of course also expensive performance-wise to introduce lots of exception-raising code everywhere since it breaks many optimisations and bloats the code. Finally, performing pointer arithmetic with signed integers is incorrect for example on on a 32-bit systems that allows up to 3gb of address space for applications (large address extensions) and unnecessary elsewhere - broadly, stuff inside the memory allocator is generated by the compiler or controlled by the standard library meaning that applications should not be forced to pay this price. If we wanted to check for overflow, the right way would be in the initial allocation location where both the size and count of objects is known. The code is updated to use the same arithmetic operator style as for refc with unchecked operations rather than disabling overflow checking wholesale in the allocator module - there are reasons for both, but going with the existing flow seems like an easier place to start. --- lib/core/typeinfo.nim | 37 +++++++++++-------------- lib/std/private/dragonbox.nim | 9 ------- lib/system.nim | 7 +---- lib/system/arc.nim | 6 ++--- lib/system/cellseqs_v1.nim | 8 +++--- lib/system/cellseqs_v2.nim | 19 ++++++------- lib/system/channels_builtin.nim | 4 --- lib/system/gc.nim | 4 +-- lib/system/gc_ms.nim | 4 +-- lib/system/gc_regions.nim | 10 ++----- lib/system/memalloc.nim | 37 +++++++------------------ lib/system/orc.nim | 48 ++++++++++++++++++--------------- lib/system/ptrarith.nim | 17 ++++++++++++ lib/system/seqs_v2.nim | 6 ----- 14 files changed, 93 insertions(+), 123 deletions(-) create mode 100644 lib/system/ptrarith.nim diff --git a/lib/core/typeinfo.nim b/lib/core/typeinfo.nim index 3928faf209..5ea776b727 100644 --- a/lib/core/typeinfo.nim +++ b/lib/core/typeinfo.nim @@ -134,19 +134,17 @@ else: proc zeroNewElements(len: int; p: pointer; addlen, elemSize, elemAlign: int) {. importCompilerProc.} -template `+!!`(a, b): untyped = cast[pointer](cast[int](a) + b) +include system/ptrarith proc getDiscriminant(aa: pointer, n: ptr TNimNode): int = assert(n.kind == nkCase) - var d: int - let a = cast[int](aa) + let a = aa +! n.offset case n.typ.size - of 1: d = int(cast[ptr uint8](a +% n.offset)[]) - of 2: d = int(cast[ptr uint16](a +% n.offset)[]) - of 4: d = int(cast[ptr uint32](a +% n.offset)[]) - of 8: d = int(cast[ptr uint64](a +% n.offset)[]) + of 1: int(cast[ptr uint8](a)[]) + of 2: int(cast[ptr uint16](a)[]) + of 4: int(cast[ptr uint32](a)[]) + of 8: cast[int](cast[ptr uint64](a)[]) else: raiseAssert "unreachable" - return d proc selectBranch(aa: pointer, n: ptr TNimNode): ptr TNimNode = let discr = getDiscriminant(aa, n) @@ -240,9 +238,6 @@ proc skipRange(x: PNimType): PNimType {.inline.} = result = x if result.kind == tyRange: result = result.base -proc align(address, alignment: int): int = - result = (address + (alignment - 1)) and not (alignment - 1) - proc `[]`*(x: Any, i: int): Any = ## Accessor for an any `x` that represents an array or a sequence. case x.rawType.kind @@ -250,7 +245,7 @@ proc `[]`*(x: Any, i: int): Any = let bs = x.rawType.base.size if i >=% x.rawType.size div bs: raise newException(IndexDefect, formatErrorIndexBound(i, x.rawType.size div bs)) - return newAny(x.value +!! i*bs, x.rawType.base) + return newAny(x.value +! i*bs, x.rawType.base) of tySequence: when defined(gcDestructors): var s = cast[ptr NimSeqV2Reimpl](x.value) @@ -259,14 +254,14 @@ proc `[]`*(x: Any, i: int): Any = let bs = x.rawType.base.size let ba = x.rawType.base.align let headerSize = align(sizeof(int), ba) - return newAny(s.p +!!

Similarly, the call can happen from a non-nim thread or inside a C library function call etc, most of which do not support reentrancy and therefore cannot be called _from_ a signal handler. The stack trace facility used in the default handler is unfortunately beyond fixing without more significant refactoring since it uses garbage-collected types in its API and implementation. As an alternative to https://github.com/nim-lang/Nim/pull/25110, this PR removes the most problematic signal handler, namely the one for SIGINT (ctrl-c) - SIGINT is special because it's meant to cause a regular shutdown of the application and crashes during SIGINT handling are both confusing and, if turned into SIGSEGV, have downstream effects like core dumps and OS crash reports. The signal handlers for the various crash scenarios remain as-is - they may too cause their own crashes but we're already going down in a bad way, so the harm is more limited - in particular, crashing during a crash handler corrupts `core`/crash dumps. Users wanting to keep their core files pristine should continue to use `-d:noSignalHandler` - this is usually the better option for production applications since they carry more detail than the Nim stack trace that gets printed. Finally, the example of a ctrl-c handler performs the same mistake of calling `echo` which is not well-defined - replace it with an example that is mostly correct (except maybe for the lack of `volatile` for the `stop` variable). --- lib/pure/cgi.nim | 13 ++++++++----- lib/system.nim | 27 +++++++++++++++++++++------ lib/system/ansi_c.nim | 2 +- lib/system/excpt.nim | 35 ++++++++++++++++++++++++++++------- lib/system/memtracker.nim | 2 +- 5 files changed, 59 insertions(+), 20 deletions(-) diff --git a/lib/pure/cgi.nim b/lib/pure/cgi.nim index 39fa25dcdc..3d5d4d932e 100644 --- a/lib/pure/cgi.nim +++ b/lib/pure/cgi.nim @@ -289,11 +289,14 @@ Content-Type: text/html proc writeErrorMessage*(data: string) = ## Tries to reset browser state and writes `data` to stdout in ## tag. - resetForStacktrace() - # We use <plaintext> here, instead of escaping, so stacktrace can - # be understood by human looking at source. - stdout.write("<plaintext>\n") - stdout.write(data) + try: + resetForStacktrace() + # We use <plaintext> here, instead of escaping, so stacktrace can + # be understood by human looking at source. + stdout.write("<plaintext>\n") + stdout.write(data) + except IOError as exc: + discard # Too bad.. proc setStackTraceStdout*() = ## Makes Nim output stacktraces to stdout, instead of server log. diff --git a/lib/system.nim b/lib/system.nim index 646a301baa..76739e51f9 100644 --- a/lib/system.nim +++ b/lib/system.nim @@ -2194,18 +2194,33 @@ when not defined(js): when declared(initGC): initGC() when notJSnotNims: - proc setControlCHook*(hook: proc () {.noconv.}) + proc setControlCHook*(hook: proc () {.noconv.}) {.raises: [], gcsafe.} ## Allows you to override the behaviour of your application when CTRL+C ## is pressed.

remove bsd_signal (#24400) POSIX signal has an identical definition to ISO C signal: https://pubs.opengroup.org/onlinepubs/9799919799/functions/signal.html ```c void (*signal(int sig, void (*func)(int)))(int); /* more readably restated by glibc as */ typedef void (*sighandler_t)(int); sighandler_t signal(int signum, sighandler_t handler); ``` However, std/posix had omitted the function's return value; this fixes that. To prevent breaking every single line of code ever that touched this binding (including mine...), I've also made it discardable. Additionally, I have noticed that bsd_signal's type signature is wrong - it should have been identical to signal. But bsd_signal was already removed in POSIX 2008, and sigaction is the recommended, portable POSIX signal interface. So I just deleted the bsd_signal binding.

By passing `-d:heaptrack --debugger:native` to compilation, calls to heaptrack will be injected when memory is being allocated and released - unlike `-d:useMalloc` this strategy also works with `refc` and the default memory pool. See https://github.com/KDE/heaptrack for usage examples. The resulting binary needs to be run with `heaptrack` and with the shared `libheaptrack_preload.so` in the `LD_LIBRARY_PATH`. --- doc/nimc.md | 2 ++ lib/system/alloc.nim | 13 +++++++++++++ 2 files changed, 15 insertions(+) diff --git a/doc/nimc.md b/doc/nimc.md index 24a2b3afe1..bb48af1370 100644 --- a/doc/nimc.md +++ b/doc/nimc.md @@ -580,6 +580,8 @@ Define Effect Currently only clang and vcc. `strip` Strip debug symbols added by the backend compiler from the executable. +`heaptrack` Track memory allocations using + [heaptrack](https://github.com/KDE/heaptrack) ====================== ========================================================= diff --git a/lib/system/alloc.nim b/lib/system/alloc.nim index fcb7ccb0c8..4109348fc2 100644 --- a/lib/system/alloc.nim +++ b/lib/system/alloc.nim @@ -837,6 +837,15 @@ when defined(gcDestructors): dec maxIters if it == nil: break +when defined(heaptrack): + const heaptrackLib = + when defined(heaptrack_inject): + "libheaptrack_inject.so" + else: + "libheaptrack_preload.so" + proc heaptrack_malloc(a: pointer, size: int) {.cdecl, importc, dynlib: heaptrackLib.} + proc heaptrack_free(a: pointer) {.cdecl, importc, dynlib: heaptrackLib.} + proc rawAlloc(a: var MemRegion, requestedSize: int): pointer = when defined(nimTypeNames): inc(a.allocCounter) @@ -959,6 +968,8 @@ proc rawAlloc(a: var MemRegion, requestedSize: int): pointer = sysAssert(isAccessible(a, result), "rawAlloc 14") sysAssert(allocInv(a), "rawAlloc: end") when logAlloc: cprintf("var pointer_%p = alloc(%ld) # %p\n", result, requestedSize, addr a) + when defined(heaptrack): + heaptrack_malloc(result, requestedSize) proc rawAlloc0(a: var MemRegion, requestedSize: int): pointer = result = rawAlloc(a, requestedSize) @@ -967,6 +978,8 @@ proc rawAlloc0(a: var MemRegion, requestedSize: int): pointer = proc rawDealloc(a: var MemRegion, p: pointer) = when defined(nimTypeNames): inc(a.deallocCounter) + when defined(heaptrack): + heaptrack_free(p) #sysAssert(isAllocatedPtr(a, p), "rawDealloc: no allocated pointer") sysAssert(allocInv(a), "rawDealloc: begin") var c = pageAddr(p) From 6f73094263ee83753aa8c3f25f13739c34d78c96 Mon Sep 17 00:00:00 2001 From: ringabout <43030857+ringabout@users.noreply.github.com> Date: Fri, 7 Nov 2025 17:06:05 +0800 Subject: [PATCH 206/448] fixes #25251;

This has unfortunately been what the codegen produces since 1.4.0 (commit https://github.com/nim-lang/Nim/commit/707367e1ca231d964ba82a92b642eb5efdc1aa7c). So string addition is now moved to a compilerproc that just uses a `for` loop. From what I can tell this is the most compatible and the fastest. Only potential problem compared to `concat` etc is with aliasing, i.e. adding an array to itself, but I'm guessing it's enough that the length from before the iteration is used, since it can only grow.

Passing a pointer to the expected value (parameter two) instead of the value itself causes the comparison to unconditionally fail, with stalls in threaded code using atomic comparisons.

However when an `skGenericParam` symbol is semchecked by `semSym` it is given its own `tyGenericParam` type rather than a `tyTypeDesc` type, this seems to be necessary for signatures to allow wildcard generic params passed to static constrained generic params (tested in #25315). The reason `semSym` is called is that `semGeneric` for generic invocations calls `matches` which sems its arguments like normal expressions. To deal with this, an expression of type `tyGenericParam` and with a `skGenericParam` sym is allowed as a type in the tuple expression. A problem is that this might consider a value with a wildcard generic param type as a type. But this is a very niche problem, and I'm not sure how to check for this. `skGenericParam` symbols stay as idents when semchecked so it can't be checked that the node is an `skGenericParam` symbol. It could be checked that it's an ident but I don't know how robust this is. And maybe there is another way to refer to a wildcard generic param type instead of just its symbol, i.e. another kind of node. This also makes #5647 finally work but a test case for that can be added after. --- compiler/semexprs.nim | 11 ++++++-- tests/tuples/tgenericparamtypetuple.nim | 34 +++++++++++++++++++++++++ 2 files changed, 43 insertions(+), 2 deletions(-) create mode 100644 tests/tuples/tgenericparamtypetuple.nim diff --git a/compiler/semexprs.nim b/compiler/semexprs.nim index 31b3770459..8384e514b0 100644 --- a/compiler/semexprs.nim +++ b/compiler/semexprs.nim @@ -3054,6 +3054,13 @@ proc semExport(c: PContext, n: PNode): PNode = s = nextOverloadIter(o, c, a) +proc isTypeTupleField(n: PNode): bool {.inline.} = + result = n.typ.kind == tyTypeDesc or + (n.typ.kind == tyGenericParam and n.typ.sym.kind == skGenericParam) + # `skGenericParam` stays as `tyGenericParam` type rather than being wrapped in `tyTypeDesc` + # would check if `n` itself is an `skGenericParam` symbol, but these symbols semcheck to an ident + # maybe check if `n` is an ident to ensure this is not a value with the generic param type? + proc semTupleConstr(c: PContext, n: PNode, flags: TExprFlags;

The test only accepted `EBADF` as a valid error code when closing a socket with pending writes. However, depending on timing, the kernel may report `ECONNRESET` or `EPIPE` instead: - **EBADF**: Socket was closed locally before kernel detected remote state - **ECONNRESET**: Remote peer sent RST packet (detected first) - **EPIPE**: Socket is no longer connected (broken pipe) All three are valid disconnection errors. The fix accepts any of them, making the test reliable across platforms. --------- Co-authored-by: Andreas Rumpf <araq4k@proton.me> --- compiler/concepts.nim | 44 ++++++--- doc/manual.md | 38 +++++++ tests/concepts/t17630.nim | 15 +++ tests/concepts/trecursive_concepts.nim | 132 +++++++++++++++++++++++++ 4 files changed, 216 insertions(+), 13 deletions(-) create mode 100644 tests/concepts/t17630.nim create mode 100644 tests/concepts/trecursive_concepts.nim diff --git a/compiler/concepts.nim b/compiler/concepts.nim index 4329e4b4bf..040089a669 100644 --- a/compiler/concepts.nim +++ b/compiler/concepts.nim @@ -13,7 +13,7 @@ import ast, astalgo, semdata, lookups, lineinfos, idents, msgs, renderer, types, layeredtable -import std/intsets +import std/[intsets, sets] when defined(nimPreviewSlimSystem): import std/assertions @@ -73,18 +73,20 @@ type MatchFlags* = enum mfDontBind # Do not bind generic parameters mfCheckGeneric # formal <- formal comparison as opposed to formal <- operand - + + ConceptTypePair = tuple[conceptId, typeId: ItemId] + ## Pair of (concept type id, implementation type id) used for cycle detection + MatchCon = object ## Context we pass around during concept matching. bindings: LayeredIdTable - marker: IntSet ## Some protection against wild runaway recursions. + marker: HashSet[ConceptTypePair] ## Tracks (concept, type) pairs being checked to detect cycles. potentialImplementation: PType ## the concrete type that might match the concept we try to match. magic: TMagic ## mArrGet and mArrPut is wrong in system.nim and ## cannot be fixed that easily. ## Thus we special case it here. concpt: PType ## current concept being evaluated - depthCount = 0 flags: set[MatchFlags] - + MatchKind = enum mkNoMatch, mkSubset, mkSame @@ -188,32 +190,48 @@ iterator traverseTyOr(t: PType): PType {. closure .}= proc matchConceptToImpl(c: PContext, f, potentialImpl: PType; m: var MatchCon): bool = assert not(potentialImpl.reduceToBase.kind == tyConcept) let concpt = f.reduceToBase - if m.depthCount > 0: - # concepts that are more then 2 levels deep are treated like - # tyAnything to stop dependencies from getting out of control + + # Handle self-referential concepts: when a concept references itself in its body + # (e.g., `A = concept; proc test(x: Self, y: A)`), the inner type A has n=nil. + # We detect this by checking if the concept has the same symbol name as the + # one we're currently matching and has no body (n=nil). + if concpt.n.isNil: + if concpt.sym != nil and m.concpt.sym != nil and + concpt.sym == m.concpt.sym: + # Self-reference: check if potentialImpl matches what we're already checking + return potentialImpl.id == m.potentialImplementation.id + # Concept without body that's not a self-reference - cannot match + return false + + # Cycle detection: track (concept, type) pairs to prevent infinite recursion. + # Returns true on cycle (coinductive semantics) to support co-dependent concepts. + let pair: ConceptTypePair = (concpt.itemId, potentialImpl.itemId) + if pair in m.marker: return true + m.marker.incl pair + var efPot = potentialImpl if potentialImpl.isSelf: if m.concpt.n == concpt.n: + m.marker.excl pair return true efPot = m.potentialImplementation - + var oldBindings = m.bindings m.bindings = newTypeMapLayer(m.bindings) let oldPotentialImplementation = m.potentialImplementation m.potentialImplementation = efPot let oldConcept = m.concpt m.concpt = concpt - + var invocation: PType = nil if f.kind in {tyGenericInvocation, tyGenericInst}: invocation = f - inc m.depthCount result = processConcept(c, concpt, invocation, oldBindings, m) - dec m.depthCount m.potentialImplementation = oldPotentialImplementation m.concpt = oldConcept m.bindings = oldBindings + m.marker.excl pair proc cmpConceptDefs(c: PContext, fn, an: PNode, m: var MatchCon): bool= if fn.kind != an.kind: @@ -610,7 +628,7 @@ proc conceptMatch*(c: PContext; concpt, arg: PType; bindings: var LayeredIdTable ## `C[S, T]` parent type that we look for.

The C codegen generates "aggregate initialization" which is invalid for opaque types. Fixes #25405. Nim code: ```nim type OpaqueInt {.importc: "_Atomic int", nodecl.} = object ContainsImportc = object normal: int opaque: OpaqueInt const c = default(ContainsImportc) ``` Resulting C code: ```c // Invalid C - cannot aggregate-init opaque type NIM_CONST ContainsImportc c = {((NI) 0), {}}; ^^ error: illegal initializer type ``` ## Solution Fix in `ccgexprs.nim`: 1. Skip opaque importc fields when building aggregate initializers 2. Use "designated initializers" (`siNamedStruct`) when opaque fields are present to avoid positional misalignment ```c // Valid C: // - opaque field is omitted and implicitly zero-initialized by C // - other fields are explitly named and initialized NIM_CONST ContainsImportc c = {.normal = ((NI) 0)}; ``` This correctly handles the case where the opaque fields might be in any order. A field is considered "opaque importc" if: - Has `sfImportc` flag - Does NOT have `tfCompleteStruct` flag - Either has `tfIncompleteStruct` OR is an object with no visible fields The `containsOpaqueImportcField` proc recursively checks all object fields, including nested objects and variant branches. Anonymous unions (from variant objects) are handled by passing an empty field name, which skips the `.fieldname = ` prefix since C anonymous unions have no field name. Note that initialization for structs without opaque importc fields remains the same as before this changeset. ## Test Coverage `tests/ccgbugs/timportc_field_init.nim` covers: - Simple struct with one importc field - Nested struct containing struct with importc field - Variant object (case object) with importc field in a branch - Array of structs with importc fields - Tuple containing struct with importc field - `completeStruct` importc types (still use aggregate init) - Sandwich case (opaque field between two non-opaque fields) - Fields with different C names (`{.importc: "c_name".}`, `{.exportc.}`) - `{.packed.}` structs with opaque fields - `{.union.}` types with opaque fields - Deep nesting (3+ levels) - Multiple opaque fields with renamed fields between them ---

Implemented by making `genComment` check if it needs to return the raw string or not. This required switching the related procs to using `Option` to handle how `nil` values were returned before. The `nil` returns were eventually ignored so just ignoring `none(T)` has the same effect.

The collector never discovers B and frees it +# while A still points to it.

To execute `A.field = B` +# the mutator must hold a reference to A, which means A has an external reference +# (from the stack) that is not a heap-to-heap edge. During trial deletion +# (`markGray`) only internal edges are subtracted from RCs, so A's external +# reference survives, `scan` finds A's RC >= 0, calls `scanBlack`, and rescues A +# and everything reachable from it — including B. In short: the mutator can only +# modify objects it can reach, but the cycle collector only frees objects nothing +# external can reach. The two conditions are mutually exclusive. +# +#[ + +The problem described in Bacon01 is: during markGray/scan, a mutator concurrently +does X.field = Z (was X→Y), changing the physical graph while the collector is tracing +it. The collector might see stale or new edges. The reasons this is still safe: + +Stale edges cancel with unbuffered decrements: If the collector sees old edge X→Y +(mutator already wrote X→Z and buffered dec(Y)), the phantom trial deletion and the +unbuffered dec cancel — Y's effective RC is correct. + +scanBlack rescues via current physical edges: If X has external refs (merged RC reflects +the mutator's access), scanBlack(X) re-traces X and follows the current physical edge X→Z, +incrementing Z's RC and marking it black.

Specifically it requires proving: + + 1. After `mergePendingRoots`, merged RCs equal logical RCs + (buffered inc/dec exactly compensate graph changes since last merge). + 2. `markGray` subtracts exactly the internal (heap→heap) edge count from + each node's merged RC, yielding `trialRC(x) = externalRefCount(x)`. + 3. `scan` correctly partitions: nodes with `trialRC ≥ 0` are rescued by + `scanBlack`; nodes with `trialRC < 0` remain white. + 4. White nodes form closed subgraphs with zero external refs → garbage. + + These properties follow from the well-known Bacon trial-deletion algorithm + and are assumed here rather than re-proved. The YRC-specific contribution + (buffered RCs, striped queues, concurrent mutators) is what our safety + proof covers — showing that concurrency does not break the preconditions + that trial deletion relies on (physical graph consistency, eventual RC + consistency after merge). + + Reference: D.F.

Three modes are provided: - `NimMode` (default, fully backward compatible), - `LaxMode` (POSIX-inspired with relaxed short option handling), - `GnuMode` (stricter GNU-style conventions). The new modes are marked as experimental in the documentation. The parser behaviour is controlled by a new `ParserRules` enum, which provides granular feature flags that modes are built from. This makes it possible for users with specific requirements to define custom rule sets by importing private symbols, this is mentioned but clearly marked as unsupported. **Backward compatibility:** The default mode preserves existing behaviour completely, with a single exception: `allowWhitespaceAfterColon` is deprecated. Now, `allowWhitespaceAfterColon` doesn't make much sense as a single tuning knob. The `ParserRule.prSepAllowDelimAfter` controls this now. As `allowWhitespaceAfterColon` had a default, most calls never mention it so they will silently migrate to the new `initOptParser` overload. To cover cases when the proc param was used at call-site, I added an overload, which modifies the default parser mode to reflect the required `allowWhitespaceAfterColon` value. Should be all smooth for most users, except the deprecation warning. The only thing I think can be classified as the breaking change is a surprising **bug** of the old parser: ```nim let p = initOptParser("-n 10 -m20 -k= 30 -40", shortNoVal = {'v'}) # ^-disappears ``` This is with the aforementioned `allowWhitespaceAfterColon` being true by default, of course. In this case the `30` token is skipped completely. I don't think that's right, so it's fixed. Things I still don't like about how the old parser and the new default mode behave: 1. **Parser behaviour is controlled by an emptiness of two containers**. This is an interesting approach. It's also made more interesting because the `shortNoVal`/`longNoVal` control both the namesakes, but *and also how their opposites (value-taking opts) work*. --- **Edit:** 2. `shortNoVal` is not mandatory: ```nim let p = initOptParser(@["-a=foo"], shortNoVal = {'a'}) # Nim, Lax parses as: (cmdShortOption, "a", "foo") # GnuMode parses as: (cmdShortOption, "a", "=foo") ``` In this case, even though the user specified `a` as no no-val, parser ignores it, relying only on the syntax to decide the kind of the argument. This is especially problematic with the modes that don't use the rule `prShortAllowSep` (GnuMode), in this case the provided input is twice invalid, regardless of the `shortNoVal`. With the current parser architecture, parsing it this way **is inevitable**, though. We don't have any way to signal the error state detected with the input, so the user is expected to validate the input for mistakes. Bundling positional arguments is nonsensical and short option can't use the separator character, so `[cmd "a", arg "=foo"]` and `[cmd "a", cmd "=", cmd "f"...]` are both out of the question **and** would complicate validating, requiring keeping track of a previous argument. Hope I'm clear enough on the issue. **Future work:** 1. Looks like the new modes are already usable, but from the discussions elsewhere it looks like we might want to support special-casing multi-digit short options (`-XX..`) to allow numerical options greater than 9. This complicates bundling, though, so requires a bit of thinking through. 2.

Fixes #25445 Without this change, the following test program: ```nim import std/sysatomics var x: ptr uint64 = cast[ptr uint64](uint64(0)) var y: ptr uint64 = cast[ptr uint64](uint64(42)) let z = atomicExchangeN(addr x, y, ATOMIC_ACQ_REL) let a = atomicCompareExchangeN(addr x, addr y, y, true, ATOMIC_ACQ_REL, ATOMIC_ACQ_REL) var v = 42 atomicStoreN(addr v, 43, ATOMIC_ACQ_REL) let w = atomicLoadN(addr v, ATOMIC_ACQ_REL) ``` ... generates this C code when compiling with `--cc:vcc`: ```c N_LIB_PRIVATE N_NIMCALL(void, NimMainModule)(void) { { NU64* T1_; NIM_BOOL T2_; NI T3_; NIM_BOOL* nimErr_; nimfr_("testexcept", "/tmp/testexcept.nim"); nimErr_ = nimErrorFlag(); nimlf_(7, "/tmp/testexcept.nim");T1_ = ((NU64*) 0); T1_ = atomicExchangeN__testexcept_u4((&x__testexcept_u2), y__testexcept_u3, ((int) 4)); if (NIM_UNLIKELY((*nimErr_))) { goto BeforeRet_; } z__testexcept_u32 = T1_; nimln_(9);T2_ = ((NIM_BOOL) 0); T2_ = atomicCompareExchangeN__testexcept_u33((&x__testexcept_u2), (&y__testexcept_u3), y__testexcept_u3, NIM_TRUE, ((int) 4), ((int) 4)); if (NIM_UNLIKELY((*nimErr_))) { goto BeforeRet_; } a__testexcept_u45 = T2_; nimln_(12);atomicStoreN__testexcept_u47(((&v__testexcept_u46)), ((NI) 43)); if (NIM_UNLIKELY((*nimErr_))) { goto BeforeRet_; } nimln_(13);T3_ = ((NI) 0); T3_ = atomicLoadN__testexcept_u53(((&v__testexcept_u46))); if (NIM_UNLIKELY((*nimErr_))) { goto BeforeRet_; } w__testexcept_u59 = T3_; BeforeRet_: ; nimTestErrorFlag(); popFrame(); } } ``` Note the repeated checks for `*nimErr_`. With this PR applied, the checks vanish: ```c N_LIB_PRIVATE N_NIMCALL(void, NimMainModule)(void) { { nimfr_("testexcept", "/tmp/testexcept.nim"); nimlf_(7, "/tmp/testexcept.nim");z__testexcept_u32 = atomicExchangeN__testexcept_u4((&x__testexcept_u2), y__testexcept_u3, ((int) 4)); nimln_(9);a__testexcept_u45 = atomicCompareExchangeN__testexcept_u33((&x__testexcept_u2), (&y__testexcept_u3), y__testexcept_u3, NIM_TRUE, ((int) 4), ((int) 4)); nimln_(12);atomicStoreN__testexcept_u47(((&v__testexcept_u46)), ((NI) 43)); nimln_(13);w__testexcept_u59 = atomicLoadN__testexcept_u53(((&v__testexcept_u46))); nimTestErrorFlag(); popFrame(); } } ``` For reference, with gcc as backend the generated code looks as follows: ```c N_LIB_PRIVATE N_NIMCALL(void, NimMainModule)(void) { { nimfr_("testexcept", "/tmp/testexcept.nim"); nimlf_(7, "/tmp/testexcept.nim");z__testexcept_u9 = __atomic_exchange_n((&x__testexcept_u2), y__testexcept_u3, __ATOMIC_ACQ_REL); nimln_(9);a__testexcept_u18 = __atomic_compare_exchange_n((&x__testexcept_u2), (&y__testexcept_u3), y__testexcept_u3, NIM_TRUE, __ATOMIC_ACQ_REL, __ATOMIC_ACQ_REL); nimln_(12);__atomic_store_n(((&v__testexcept_u19)), ((NI) 43), __ATOMIC_ACQ_REL); nimln_(13);w__testexcept_u29 = __atomic_load_n(((&v__testexcept_u19)), __ATOMIC_ACQ_REL); nimTestErrorFlag(); popFrame(); } } ``` With this PR the program from #25445 yields the correct output `Error: unhandled exception: index 4 not in 0 .. 3 [IndexDefect]` instead of crashing with a SIGSEGV.

A trailing `$` at the end of a replacement string could read out of bounds via `how[i + 1]`; this now raises `ValueError` instead. 2. Numeric capture parsing used `id += (id * 10) + digit` instead of `id = (id * 10) + digit`, so multi-digit refs were parsed incorrectly (e.g. `$12` resolved as capture 13 instead of 12). 4. Unterminated named replacement syntax (e.g. `${foo)` is now rejected with ValueError instead of being accepted and parsed inconsistently.

Which is really annoying given they are regular procs just named a bit differently. Initially, I thought the problem was with nim-lang/langserver and opened an issue there: https://github.com/nim-lang/langserver/issues/380 But after an investigation, it turned out the issue is fixed on the nimsuggest side. Strangely enough, calling `outline foo.nim:0:0` in nimsuggest manually does show \`+\` as well as regular procs (e.g. `foo`) but when nimsuggest is invoked from lsp only `foo` would be there. Anyway, with this fix all procs appear on the symbol lists. --- nimsuggest/nimsuggest.nim | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) diff --git a/nimsuggest/nimsuggest.nim b/nimsuggest/nimsuggest.nim index 6ee1433c07..2deac2c469 100644 --- a/nimsuggest/nimsuggest.nim +++ b/nimsuggest/nimsuggest.nim @@ -1018,7 +1018,7 @@ proc outlineNode(graph: ModuleGraph, n: PNode, endInfo: TLineInfo, infoPairs: Su if n.kind == nkSym and n.sym.checkSymbol(n.info): graph.suggestResult(n.sym, n.sym.info, ideOutline, endInfo.line, endInfo.col) return true - elif n.kind == nkIdent: + elif n.kind in {nkIdent, nkAccQuoted}: let symData = findByTLineInfo(n.info, infoPairs) if symData != nil and symData.sym.checkSymbol(symData.info): let sym = symData.sym @@ -1028,7 +1028,7 @@ proc outlineNode(graph: ModuleGraph, n: PNode, endInfo: TLineInfo, infoPairs: Su proc handleIdentOrSym(graph: ModuleGraph, n: PNode, endInfo: TLineInfo, infoPairs: SuggestFileSymbolDatabase): bool = result = false for child in n: - if child.kind in {nkIdent, nkSym}: + if child.kind in {nkIdent, nkAccQuoted, nkSym}: if graph.outlineNode(child, endInfo, infoPairs): return true elif child.kind == nkPostfix: From c033ccd2e5fb86e7d6133c21b39a6d6c022d5ac8 Mon Sep 17 00:00:00 2001 From: Andreas Rumpf <rumpf_a@web.de> Date: Thu, 5 Mar 2026 12:40:48 +0100 Subject: [PATCH 345/448] fixes #25552 (#25582) --- compiler/injectdestructors.nim | 93 ++++++++++++++++++---------------- 1 file changed, 48 insertions(+), 45 deletions(-) diff --git a/compiler/injectdestructors.nim b/compiler/injectdestructors.nim index f23e6ed04d..8094a2af3a 100644 --- a/compiler/injectdestructors.nim +++ b/compiler/injectdestructors.nim @@ -72,9 +72,11 @@ proc hasDestructor(c: Con; t: PType): bool {.inline.} = if not result and c.graph.config.selectedGC in {gcArc, gcOrc, gcYrc, gcAtomicArc}: assert(not containsGarbageCollectedRef(t)) -proc getTemp(c: var Con; s: var Scope; typ: PType; info: TLineInfo): PNode = +proc getTemp(c: var Con; s: var Scope; typ: PType; info: TLineInfo; needsInit: bool): PNode = let sym = newSym(skTemp, getIdent(c.graph.cache, ":tmpD"), c.idgen, c.owner, info) sym.typ = typ + if not needsInit: + sym.incl sfNoInit s.vars.add(sym) result = newSymNode(sym) @@ -302,7 +304,7 @@ proc genSink(c: var Con; s: var Scope; dest, ri: PNode; flags: set[MoveOrCopyFla if deepAliases(dest, ri): # consider: x = x + y, it is wrong to destroy the destination first!

The Nim syntax highlighter in `docutils/highlite.nim` incorrectly tokenizes character literals that appear after punctuation characters, such as all kinds of brackets. For `echo('v', "hello")`, the tokenizer treated the first `'` as punctuation because the preceding token was punctuation `(`. As a result, the second `'` (after `v`) was interpreted as the start of a character literal and the literal incorrectly extended to the end of the line. See other examples in the screenshot: <img width="508" height="266" alt="Screenshot 2026-03-04 at 16-09-06 _y_test" src="https://github.com/user-attachments/assets/94d991ae-79d2-4208-a046-6ed4ddcb5c34" /> This regression originates from a condition added in PR #23015 that prevented opening a `gtCharLit` token when the previous token kind was punctuation. Nim syntax allows character literals after punctuation such as `(`, `[`, `{`, `:`, `;`, or `,`, of course.

I hit the same bug as #25265 for my own project but #25269 does not fix it, I think because the type in my case is a `tyGenericInst` which does not trigger the generation here. First I thought of skipping abstract type kinds instead of checking for a raw `tyObject`, which fixes my problem. But in general this could maybe also be encountered for `tyTuple` and `tySequence` etc. So I figured it might just be safest to not filter on specific type kinds, ~~which is done now~~ (edit: broke CI). Maybe this has a slight cost on codegen performance though.

Possibly higher levels, too, but this PR is conservative and only takes it out at the 2->1 transition. --- compiler/lineinfos.nim | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/compiler/lineinfos.nim b/compiler/lineinfos.nim index dc8708c3e4..bb3f519535 100644 --- a/compiler/lineinfos.nim +++ b/compiler/lineinfos.nim @@ -266,7 +266,7 @@ proc computeNotesVerbosity(): array[0..3, TNoteKinds] = result = default(array[0..3, TNoteKinds]) result[3] = {low(TNoteKind)..high(TNoteKind)} - {warnObservableStores, warnResultUsed, warnAnyEnumConv, warnBareExcept, warnStdPrefix, warnSystemRangeConversion} result[2] = result[3] - {hintStackTrace, hintExtendedContext, hintDeclaredLoc, hintProcessingStmt} - result[1] = result[2] - {warnProveField, warnProveIndex, + result[1] = result[2] - {warnImplicitRangeConversion, warnProveField, warnProveIndex, warnGcUnsafe, hintPath, hintDependency, hintCodeBegin, hintCodeEnd, hintSource, hintGlobalVar, hintGCStats, hintMsgOrigin, hintPerformance} result[0] = result[1] - {hintSuccessX, hintSuccess, hintConf, From b1c68bbab4ad9d0cf98932a87aded1abf9a434c0 Mon Sep 17 00:00:00 2001 From: ringabout <43030857+ringabout@users.noreply.github.com> Date: Fri, 20 Mar 2026 04:25:11 +0800 Subject: [PATCH 364/448] fixes #25611; `t.state != Sealed` (#25622) fixes #25611 This pull request updates the `propagateToOwner` procedure in `compiler/ast.nim` to handle sealed types more robustly during incremental compilation (IC) reloads. The main change is the addition of an assertion to ensure that sealed types already have the necessary propagated flags, preventing incorrect state during IC reloads.

The most important changes are summarized below: ### Compiler logic fix * In `compiler/typekeys.nim`, the `typeKey` procedure was updated to iterate over all elements in `t.sonsImpl` starting from index 0 instead of 1, ensuring that all type sons are considered during type key generation. ### Test suite improvements * The test file `tests/ic/tenum.nim` was renamed to `tests/ic/tmiscs.nim`, and its output expectations were updated to reflect the new test cases. * Added new test cases to `tests/ic/tmiscs.nim` to cover sink and move semantics, including the definition of a `BigObj` type and a `consume` procedure that demonstrates moving and consuming large objects. ```nim # Sink and move semantics type BigObj = object data: seq[int] proc consume(x: sink BigObj) = echo x.data.len var b = BigObj(data: @[1, 2, 3, 4, 5]) consume(move b) ``` gives ``` error: passing 'tySequence__qwqHTkRvwhrRyENtudHQ7g' (aka 'struct tySequence__qwqHTkRvwhrRyENtudHQ7g') to parameter of incompatible type 'tySequence__cTyVHeHOWk5jStsToosJ8Q' (aka 'struct tySequence__cTyVHeHOWk5jStsToosJ8Q') 84 | eqdestroy___sysma2dyk_u75((*dest_p0).data); ``` follows up https://github.com/nim-lang/Nim/pull/25614 --- compiler/typekeys.nim | 2 +- tests/ic/{tenum.nim => tmiscs.nim} | 17 +++++++++++++++-- 2 files changed, 16 insertions(+), 3 deletions(-) rename tests/ic/{tenum.nim => tmiscs.nim} (63%) diff --git a/compiler/typekeys.nim b/compiler/typekeys.nim index 06e633b317..d1c77ec3fe 100644 --- a/compiler/typekeys.nim +++ b/compiler/typekeys.nim @@ -274,7 +274,7 @@ proc typeKey(c: var Context; t: PType; flags: set[ConsiderFlag]; conf: ConfigRef c.typeKey(t.sonsImpl[0], flags-{CoIgnoreRange}, conf) else: withTree c.m, toNifTag(t.kind): - for i in 1..<t.sonsImpl.len: + for i in 0..<t.sonsImpl.len: c.typeKey t.sonsImpl[i], flags, conf if tfNotNil in t.flagsImpl and CoType notin flags: c.m.addIdent "´notnil" diff --git a/tests/ic/tenum.nim b/tests/ic/tmiscs.nim similarity index 63% rename from tests/ic/tenum.nim rename to tests/ic/tmiscs.nim index 30fd3cbd1f..21e4c20daf 100644 --- a/tests/ic/tenum.nim +++ b/tests/ic/tmiscs.nim @@ -1,6 +1,8 @@ discard """ - disabled: "linux" - output: "42" + output: ''' +42 +5 +''' """ # Object variant / case object @@ -20,3 +22,14 @@ proc newInt(v: int): ref Node = let n = newInt(42) echo n.intVal + +# Sink and move semantics +type + BigObj = object + data: seq[int] + +proc consume(x: sink BigObj) = + echo x.data.len + +var b = BigObj(data: @[1, 2, 3, 4, 5]) +consume(move b) \ No newline at end of file From 8bb63b475b4a8ecb4a6dbc753ab24ddd3ab398ca Mon Sep 17 00:00:00 2001 From: ringabout <43030857+ringabout@users.noreply.github.com> Date: Mon, 23 Mar 2026 16:35:30 +0800 Subject: [PATCH 366/448] fixes global tuple unpacking for `nim ic` (#25624) This pull request includes a few targeted changes across the codebase, primarily focusing on improving symbol locality detection in the compiler, adding a utility function for integer division and modulus, and simplifying a test case. - **Compiler Improvements** * Improved the `isLocalSym` function in `compiler/ast2nif.nim` to more accurately determine if a symbol is local by checking that the symbol's owner is not a module. - **Utility Function Addition** * Added a new `divmod` procedure in `tests/ic/tmiscs.nim` that returns both the quotient and remainder of integer division, along with a usage example. - **Test Simplification** * Simplified the `showMeters` test in `tests/ic/tconverter.nim` by removing a floating-point assertion, leaving only an output statement. ------------------------------------------------------------------------------------------------------------------ ```nim proc divmod(a, b: int): (int, int) = (a div b, a mod b) let (q, r) = divmod(17, 5) echo q echo r ``` gives `Error: unhandled exception: local symbol 'tmpTuple.0' not found in localSyms.

The most significant change is a refinement in how type flags are handled for procedure and function types in the compiler, which improves correctness in type allowance checks. Additionally, the test suite is expanded to cover more complex scenarios with lent types and table lookups. **Compiler improvements:** * Refined the handling of type flags in `typeAllowedAux` for procedure and function types by introducing `innerFlags`, which removes certain flags (`taObjField`, `taTupField`, `taIsOpenArray`) before recursing into parameter and return types. This ensures more accurate type checking and prevents inappropriate flag propagation. **Testing enhancements:** * Added new test blocks in `tests/lent/tlents.nim` to cover lent procedure types stored in objects and used as table values, including a function that retrieves such procedures from a table by key. * Introduced a test case for an object containing a lent procedure field, ensuring correct behavior when accessing and using these fields. --- compiler/typeallowed.nim | 7 ++++--- tests/lent/tlents.nim | 22 ++++++++++++++++++++++ 2 files changed, 26 insertions(+), 3 deletions(-) diff --git a/compiler/typeallowed.nim b/compiler/typeallowed.nim index 80b532371c..05584341b6 100644 --- a/compiler/typeallowed.nim +++ b/compiler/typeallowed.nim @@ -99,12 +99,13 @@ proc typeAllowedAux(marker: var IntSet, typ: PType, kind: TSymKind, if isInlineIterator(typ) and kind in {skVar, skLet, skConst, skParam, skResult}: # only closure iterators may be assigned to anything. result = t -

I want to proceed with RFC [#562](https://github.com/nim-lang/RFCs/issues/562) and this is the main blocker for composability. Fixes #22098 and, arguably, #19206 ```nim import std/strutils template collect[T](it: iterable[T]): seq[T] = block: var res: seq[T] = @[] for x in it: res.add x res const text = "a b c d" let words = text.split.collect() doAssert words == @[ "a", "b", "c", "d" ] ``` In cases like `strutils.split`, where both proc and iterator overload exists, the compiler resolves to the `func` overload causing a type mismatch. The old mode resolved `text.split` to `seq[string]` before the surrounding `iterable[T]` requirement was applied, so the argument no longer matched this template. It should be noted that, compared to older sequtils templates, composable chains based on `iterable[T]` require an iterator-producing expression, e.g. `"foo".items.iterableTmpl()` rather than just `"foo".iterableTmpl()`. This is actually desirable: it keeps the iteration boundary explicit and makes iterable-driven templates intentionally not directly interchangeable with older untyped/loosely-typed templates like those in `sequtils`, whose internal iterator setup we have zero control over (e.g. hard-coding adapters like `items`). Also, I noticed in `semstmts` that anonymous iterators are always `closure`, which is not that surprising if you think about it, but still I added a paragraph to the manual. Regarding implementation: From what I gathered, the root cause is that `semOpAux` eagerly pre-types all arguments with plain flags before overload resolution begins, so by the time `prepareOperand` processes `split` against the `iterable[T]`, the wrong overload has already won. The fix touches a few places: - `prepareOperand` in `sigmatch.nim`: When `formal.kind == tyIterable` and the argument was already typed as something else, it's re-semchecked with the `efPreferIteratorForIterable` flag. The recheck is limited to direct calls (`a[0].kind in {nkIdent, nkAccQuoted, nkSym, nkOpenSym}`) to avoid recursing through `semIndirectOp`/`semOpAux` again. - `iteratorPreference` field `TCandidate`, checked before `genericMatches` in `cmpCandidates`, gives the iterator overload a win without touching the existing iterator heuristic used by `for` loops. **Limitations:** The implementation is still flag-driven rather than purely formal-driven, so the behaviour is a bit too broad `efWantIterable` can cause iterator results to be wrapped as `tyIterable` in iterable-admitting contexts, not only when `iterable[T]` match is being processed. `iterable[T]` still does not accept closure iterator values such as`iterator(): T {.closure.}`. It only matches the compiler's internal `tyIterable`, not arbitrary iterator-typed values. The existing iterator-preference heuristic is still in place, because when I tried to remove it, some loosely-related regressions happened. In particular, ordinary iterator-admitting contexts and iterator chains still rely on early iterator preference during semchecking, before the compiler has enough surrounding context to distinguish between value/iterator producing overloads. Full heuristic removal would require a broader refactor of dot-chain/intermediate-expression semchecking, which is just too much for me ATM. This PR narrows only the tyIterable-specific cases. **Future work:** Rework overload resolution to preserve additional information of matching iterator overloads for calls up to the point where the iterator-requiring context is established, to avoid re-sem in `prepareOperand`. Currently there's no good channel to store that information. Nodes can get rewritten, TCandidate doesn't live long enough, storing in Context or some side-table raises the question how to properly key that info. --- compiler/semcall.nim | 10 +++++-- compiler/semdata.nim | 13 ++++++++- compiler/semexprs.nim | 7 +++-- compiler/semstmts.nim | 27 +++++++++++------- compiler/sigmatch.nim | 26 +++++++++++++++-- doc/manual.md | 44 ++++++++++++++++------------- tests/iter/tinlineitervalue.nim | 6 ++++ tests/iter/titerablereso.nim | 50 +++++++++++++++++++++++++++++++++ 8 files changed, 144 insertions(+), 39 deletions(-) create mode 100644 tests/iter/tinlineitervalue.nim create mode 100644 tests/iter/titerablereso.nim diff --git a/compiler/semcall.nim b/compiler/semcall.nim index 29d19875d4..986b847fd2 100644 --- a/compiler/semcall.nim +++ b/compiler/semcall.nim @@ -160,9 +160,13 @@ proc pickBestCandidate(c: PContext, headSymbol: PNode, addTypeBoundSymbols(c.graph, arg.typ, name, filter, symMarker, syms) if z.state == csMatch: - # little hack so that iterators are preferred over everything else: + # Iterator preference is heuristic in iterator-admitting contexts. + # The dedicated iterable path uses `iteratorPreference`, other + # context use exact-match bump if sym.kind == skIterator: - if not (efWantIterator notin flags and efWantIterable in flags): + if efPreferIteratorForIterable in flags: + inc(z.iteratorPreference) + elif not (efWantIterator notin flags and efWantIterable in flags): inc(z.exactMatches, 200) else: dec(z.exactMatches, 200) @@ -671,7 +675,7 @@ proc bracketNotFoundError(c: PContext;

This can significantly improve performance for such types by avoiding per-element loops. Key changes: ### Compiler code generation improvements * Added the `elemSupportsCopyMem` function in `compiler/liftdestructors.nim` to detect if a sequence's element type is trivially copyable (no GC refs, no destructors). * Updated the `fillSeqOp` procedure to use a new `genBulkCopySeq` code path for eligible element types, generating a call to `nimCopySeqPayload` for efficient bulk copying. Fallback to the element-wise loop remains for non-trivial types.

This is only used for types that are safe for such an operation. These changes collectively improve the efficiency of sequence operations for simple types, while maintaining correctness for complex types. ### Benchmarked the original micro-benchmark: refc: 3.52s user 0.02s system 99% cpu 3.538 total orc (after change): 3.46s user 0.01s system 99% cpu 3.476 total --------- Co-authored-by: Copilot <175728472+Copilot@users.noreply.github.com> --- compiler/liftdestructors.nim | 31 +++++++++++++++++++++++++++++-- compiler/semmagic.nim | 5 +---- compiler/types.nim | 4 ++++ lib/system/seqs_v2.nim | 10 ++++++++++ 4 files changed, 44 insertions(+), 6 deletions(-) diff --git a/compiler/liftdestructors.nim b/compiler/liftdestructors.nim index e05b14d460..a2f3c94cde 100644 --- a/compiler/liftdestructors.nim +++ b/compiler/liftdestructors.nim @@ -620,11 +620,34 @@ proc checkSelfAssignment(c: var TLiftCtx; t: PType; body, x, y: PNode) = cond.typ = getSysType(c.g, c.info, tyBool) body.add genIf(c, cond, newTreeI(nkReturnStmt, c.info, newNodeI(nkEmpty, c.info))) +proc genBulkCopySeq(c: var TLiftCtx; t: PType; body, x, y: PNode) = + ## Generates a call to nimCopySeqPayload for bulk memcpy of seq data. + let elemType = t.elementType + let sym = magicsys.getCompilerProc(c.g, "nimCopySeqPayload") + if sym == nil: + localError(c.g.config, c.info, "system module needs: nimCopySeqPayload") + return + var sizeOf = genBuiltin(c, mSizeOf, "sizeof", newNodeIT(nkType, c.info, elemType)) + sizeOf.typ = getSysType(c.g, c.info, tyInt) + var alignOf = genBuiltin(c, mAlignOf, "alignof", newNodeIT(nkType, c.info, elemType)) + alignOf.typ = getSysType(c.g, c.info, tyInt) + let call = newNodeI(nkCall, c.info) + call.add newSymNode(sym) + call.add newTreeIT(nkAddr, c.info, makePtrType(c.fn, x.typ, c.idgen), x) + call.add newTreeIT(nkAddr, c.info, makePtrType(c.fn, y.typ, c.idgen), y) + call.add sizeOf + call.add alignOf + call.typ = sym.typ.returnType + body.add call + proc fillSeqOp(c: var TLiftCtx; t: PType; body, x, y: PNode) = case c.kind of attachedDup: body.add setLenSeqCall(c, t, x, y) - forallElements(c, t, body, x, y) + if supportsCopyMem(t.elementType): + genBulkCopySeq(c, t, body, x, y) + else: + forallElements(c, t, body, x, y) of attachedAsgn, attachedDeepCopy: # we generate: # if x.p == y.p: @@ -633,9 +656,13 @@ proc fillSeqOp(c: var TLiftCtx; t: PType; body, x, y: PNode) = # var i = 0 # while i < y.len: dest[i] = y[i]; inc(i) # This is usually more efficient than a destroy/create pair. + # For trivially copyable types, use bulk copyMem instead of element loop. checkSelfAssignment(c, t, body, x, y) body.add setLenSeqCall(c, t, x, y) - forallElements(c, t, body, x, y) + if supportsCopyMem(t.elementType): + genBulkCopySeq(c, t, body, x, y) + else: + forallElements(c, t, body, x, y) of attachedSink: let moveCall = genBuiltin(c, mMove, "move", x) moveCall.add y diff --git a/compiler/semmagic.nim b/compiler/semmagic.nim index 87e085d4fd..5e4388d3c6 100644 --- a/compiler/semmagic.nim +++ b/compiler/semmagic.nim @@ -232,10 +232,7 @@ proc evalTypeTrait(c: PContext; traitCall: PNode, operand: PType, context: PSym) of "stripGenericParams": result = uninstantiate(operand).toNode(traitCall.info) of "supportsCopyMem": - let t = operand.skipTypes({tyVar, tyLent, tyGenericInst, tyAlias, tySink, tyInferred}) - let complexObj = containsGarbageCollectedRef(t) or - hasDestructor(t) - result = newIntNodeT(toInt128(ord(not complexObj)), traitCall, c.idgen, c.graph) + result = newIntNodeT(toInt128(ord(supportsCopyMem(operand))), traitCall, c.idgen, c.graph) of "canFormCycles": result = newIntNodeT(toInt128(ord(types.canFormAcycle(c.graph, operand))), traitCall, c.idgen, c.graph) of "hasDefaultValue": diff --git a/compiler/types.nim b/compiler/types.nim index e18f97ff36..62831624b9 100644 --- a/compiler/types.nim +++ b/compiler/types.nim @@ -1779,3 +1779,7 @@ proc reduceToBase*(f: PType): PType = result = f.elementType else: result = f + +proc supportsCopyMem*(t: PType): bool = + let t = t.skipTypes({tyVar, tyLent, tyGenericInst, tyAlias, tySink, tyInferred}) + result = not containsGarbageCollectedRef(t) and not hasDestructor(t) diff --git a/lib/system/seqs_v2.nim b/lib/system/seqs_v2.nim index 154b443460..fefb6e914c 100644 --- a/lib/system/seqs_v2.nim +++ b/lib/system/seqs_v2.nim @@ -272,6 +272,16 @@ proc newSeq[T](s: var seq[T], len: Natural) = proc sameSeqPayload(x: pointer, y: pointer): bool {.compilerRtl, inl.} = result = cast[ptr NimRawSeq](x)[].p == cast[ptr NimRawSeq](y)[].p +proc nimCopySeqPayload(dest: pointer, src: pointer, elemSize: int, elemAlign: int) {.compilerRtl, inl.} = + ## Bulk-copies the payload data from src seq to dest seq using copyMem. + ## Only valid for trivially copyable element types (no GC refs, no destructors). + ## Caller must have already ensured dest has the correct length and capacity + ## (e.g. via setLen). + let d = cast[ptr NimRawSeq](dest) + let s = cast[ptr NimRawSeq](src) + if s.len > 0: + let headerSize = align(sizeof(NimSeqPayloadBase), elemAlign) + copyMem(d.p +!

This happens because #24841 changed the code which gives explicit destructor calls the proper attached destructor to use `replaceHookMagic`, which now skips `abstractVar` from the type to get the destructor whereas previously it was just `{tyAlias, tyVar}`. This skips `tyGenericInst` and also `tyDistinct`. I cannot explain why the skipped `tyGenericInst` does not have the right destructor but it's not really unexpected, and skipping `tyDistinct` is just wrong. To fix this, just `{tyAlias, tyVar, tySink}` are skipped. --- compiler/semdata.nim | 10 +++++----- compiler/sempass2.nim | 2 +- 2 files changed, 6 insertions(+), 6 deletions(-) diff --git a/compiler/semdata.nim b/compiler/semdata.nim index 0fc000051c..4710d7c0d6 100644 --- a/compiler/semdata.nim +++ b/compiler/semdata.nim @@ -741,7 +741,7 @@ proc replaceHookMagic*(c: PContext, n: PNode, kind: TTypeAttachedOp): PNode = case kind of attachedDestructor: result = n - let t = n[1].typ.skipTypes(abstractVar) + let t = n[1].typ.skipTypes({tyAlias, tyVar, tySink}) let op = getAttachedOp(c.graph, t, attachedDestructor) if op != nil: result[0] = newSymNode(op) @@ -753,13 +753,13 @@ proc replaceHookMagic*(c: PContext, n: PNode, kind: TTypeAttachedOp): PNode = result[1] = skipAddr(n[1]) of attachedTrace: result = n - let t = n[1].typ.skipTypes(abstractVar) + let t = n[1].typ.skipTypes({tyAlias, tyVar, tySink}) let op = getAttachedOp(c.graph, t, attachedTrace) if op != nil: result[0] = newSymNode(op) of attachedDup: result = n - let t = n[1].typ.skipTypes(abstractVar) + let t = n[1].typ.skipTypes({tyAlias, tyVar, tySink}) let op = getAttachedOp(c.graph, t, attachedDup) if op != nil: result[0] = newSymNode(op) @@ -769,7 +769,7 @@ proc replaceHookMagic*(c: PContext, n: PNode, kind: TTypeAttachedOp): PNode = result.add boolLit of attachedWasMoved: result = n - let t = n[1].typ.skipTypes(abstractVar) + let t = n[1].typ.skipTypes({tyAlias, tyVar, tySink}) let op = getAttachedOp(c.graph, t, attachedWasMoved) if op != nil: result[0] = newSymNode(op) @@ -780,7 +780,7 @@ proc replaceHookMagic*(c: PContext, n: PNode, kind: TTypeAttachedOp): PNode = result = c.semAsgnOpr(c, n, nkAsgn) of attachedDeepCopy: result = n - let t = n[1].typ.skipTypes(abstractVar) + let t = n[1].typ.skipTypes({tyAlias, tyVar, tySink}) let op = getAttachedOp(c.graph, t, kind) if op != nil: result[0] = newSymNode(op) diff --git a/compiler/sempass2.nim b/compiler/sempass2.nim index 91ade858e9..35901ed960 100644 --- a/compiler/sempass2.nim +++ b/compiler/sempass2.nim @@ -1164,7 +1164,7 @@ proc trackCall(tracked: PEffects; n: PNode) = var (isHook, opKind) = findHookKind(a.sym.name.s) if isHook: # rebind type bounds operations after createTypeBoundOps call - let t = n[1].typ.skipTypes({tyAlias, tyVar}) + let t = n[1].typ.skipTypes({tyAlias, tyVar, tySink}) if a.sym != getAttachedOp(tracked.graph, t, opKind): createTypeBoundOps(tracked, t, n.info, explicit = true) # replace builtin hooks with lifted ones From 115ec7a433a7c55b596f526b7ca9187cc50fc980 Mon Sep 17 00:00:00 2001 From: lou15b <lou15b@users.noreply.github.com> Date: Tue, 7 Apr 2026 18:52:12 -0400 Subject: [PATCH 394/448] Fixes #25710 - nimsuggest outline misses methods (#25711) This adds methods to the list generated by the `outline` command for `nimsuggest --v3` and `nimsuggest --v4`.

The main change is the introduction of a helper function to properly resolve borrowed routine symbols, which is then used in multiple places to ensure correct symbol resolution. Additionally, a new test case is added to cover a previously reported bug related to borrowed iterators on distinct types. **Compiler improvements:** * Added `resolveBorrowedRoutineSym` helper function to follow borrow aliases and retrieve the underlying implementation symbol for borrowed routines. This centralizes and clarifies the logic for resolving borrowed symbols. * Updated `transformSymAux` and `transformFor` to use the new helper function, replacing duplicated logic and improving correctness when handling borrowed routines.

The main improvement is that the code now distinguishes between regular and uninitialized resizing based on whether the sequence's element type supports bulk memory copying, which can lead to more efficient code generation. **Improvements to sequence resizing and copying logic:** * Modified `setLenSeqCall` to accept a `noinit` parameter, allowing it to choose between `setLen` and `setLenUninit` operations, and to select the appropriate magic for each case. * Updated `fillSeqOp` to determine if bulk memory copy is supported and, if so, call `setLenSeqCall` with `noinit = true` and perform a bulk copy; otherwise, it defaults to element-wise copying. This logic is now applied in both relevant locations in the function.

nim ic with destructors (#25723) fixes #25637 This pull request refactors the way the `sfInjectDestructors` flag is set on symbols during lambda lifting in the Nim compiler. The main change is the introduction of a helper procedure to encapsulate the logic for marking symbols that require destructor injection, improving code clarity and maintainability. Refactoring and code quality improvements: * Introduced the `markInjectDestructors` procedure to encapsulate the logic for marking a symbol with the `sfInjectDestructors` flag, ensuring that `backendEnsureMutable` is always called before modifying the symbol's flags. * Replaced direct flag manipulation (`owner.incl sfInjectDestructors` and `prc.incl sfInjectDestructors`) with calls to the new `markInjectDestructors` procedure in multiple locations, including `makeClosure`, `createTypeBoundOpsLL`, and `rawClosureCreation`.

But maybe this is a reasonable trade since it only happens on explicit `=sink`/`=copy` calls. Any way to optimize it requires detecting either the type or the found hook as a trivial assignment. I am not sure how to do these, the hook isn't like destructors that propagate empty statements in `liftdestructors` (which is what `isTrivial` checks for), it needs to propagate simple assignments instead. And there is no logic for the type, `tfHasAsgn` is misleading since it only checks if the destructor is trivial, because there is no check for a trivial assignment.

Now, if the types match (ignoring distinctness and shallow range differences), the argument is recursively processed; otherwise, it falls back to a fast assignment. This prevents incorrect assignments when dealing with type conversions and distinct types. ### Testing for distinct types and ARC * Added a new test `tdistinct_for_nodup.nim` to ensure correct iteration and memory management for distinct sequences of large arrays under ARC. The test checks that the sequence length remains unchanged during iteration, helping catch regressions related to ARC and distinct types. --- compiler/transf.nim | 5 +++++ tests/arc/tdistinct_for_nodup.nim | 33 +++++++++++++++++++++++++++++++ 2 files changed, 38 insertions(+) create mode 100644 tests/arc/tdistinct_for_nodup.nim diff --git a/compiler/transf.nim b/compiler/transf.nim index 399a8c468a..3059d8fe6b 100644 --- a/compiler/transf.nim +++ b/compiler/transf.nim @@ -702,6 +702,11 @@ proc putArgInto(arg: PNode, formal: PType): TPutArgInto = of nkAddr, nkHiddenAddr: result = putArgInto(arg[0], formal) if result == paViaIndirection: result = paFastAsgn + of nkHiddenStdConv, nkHiddenSubConv, nkConv: + if compareTypes(arg.typ, arg[1].typ, dcEqIgnoreDistinct, {IgnoreRangeShallow}): + result = putArgInto(arg[1], formal) + else: + result = paFastAsgn of nkCurly, nkBracket: for i in 0..<arg.len: if putArgInto(arg[i], formal) != paDirectMapping: diff --git a/tests/arc/tdistinct_for_nodup.nim b/tests/arc/tdistinct_for_nodup.nim new file mode 100644 index 0000000000..427f6b2b02 --- /dev/null +++ b/tests/arc/tdistinct_for_nodup.nim @@ -0,0 +1,33 @@ +discard """ + cmd: '''nim c --mm:arc --expandArc:foo $file''' + nimout: ''' +--expandArc: foo + +var broken_cursor +block :tmp: + var i + var i_1 = 0 + let L = len(seq[Large](broken_cursor)) + block :tmp_1: + while i_1 < L: + i = seq[Large](broken_cursor)[i_1] + discard i + {.push, overflowChecks: false.} + inc(i_1, 1) + {.pop.} +-- end of expandArc ------------------------ +''' +""" + + +type + Large = array[1024, byte] + List = distinct seq[Large] + +proc foo = + var + broken: List + for i in seq[Large](broken): + discard i + +foo() \ No newline at end of file From c22819ef1739979dd3b73923a8f173b326c65bb3 Mon Sep 17 00:00:00 2001 From: ringabout <43030857+ringabout@users.noreply.github.com> Date: Fri, 17 Apr 2026 16:00:00 +0800 Subject: [PATCH 413/448] fixes #25732;

JS backend crashes when returning `Option[T]` with custom `=destroy` (#25752) fixes #25751 This pull request improves the JavaScript backend code generation and expands test coverage, particularly around temporary and loop variables, as well as object destruction behavior. The main changes include updating the code generator to handle more symbol kinds and adding tests to ensure proper destruction and option handling. **JavaScript code generation improvements:** * Updated `genSymAddr` in `compiler/jsgen.nim` to support additional symbol kinds, specifically `skTemp` and `skForVar`, ensuring correct address generation for temporaries and loop variables. **Test suite enhancements:** * Added tests in `tests/js/test2.nim` to verify correct behavior of option types, object destruction (`=destroy`), and to check for backend-specific crashes. This includes printing results of option-returning functions and confirming destruction messages. * Updated expected output in `tests/js/test2.nim` to include results from new tests and destruction messages, ensuring the test suite reflects the latest code behavior. --- compiler/jsgen.nim | 2 +- tests/js/test2.nim | 19 ++++++++++++++++++- 2 files changed, 19 insertions(+), 2 deletions(-) diff --git a/compiler/jsgen.nim b/compiler/jsgen.nim index 98153490df..fd82a127f7 100644 --- a/compiler/jsgen.nim +++ b/compiler/jsgen.nim @@ -1544,7 +1544,7 @@ proc genSymAddr(p: PProc, n: PNode, typ: PType, r: var TCompRes) = r.res = s.loc.snippet r.address = "" r.typ = etyNone - of skVar, skLet, skResult: + of skVar, skLet, skResult, skTemp, skForVar: r.kind = resExpr let jsType = mapType(p): if typ.isNil: diff --git a/tests/js/test2.nim b/tests/js/test2.nim index fa857ccc5c..c4cb2a25d3 100644 --- a/tests/js/test2.nim +++ b/tests/js/test2.nim @@ -4,7 +4,12 @@ js 3.14 7 1 -21550 --21550''' +-21550 +none(TT) +() +destroyed +destroyed +''' """ # This file tests the JavaScript generator @@ -56,3 +61,15 @@ proc foo09() = const y = 86400 echo (x - (y - 1)) div y # Still gives `-21551` foo09() + +import std/options + +type TT = object + +proc `=destroy`(x: TT) = echo "destroyed" + +func test1: Option[TT] = discard +func test2: TT = discard + +echo test1() # Crash in JS backend, not crash in C backend +echo test2() # Not crash From 5948dbbeed1a62f66185c09f1ceba2864dea4c4c Mon Sep 17 00:00:00 2001 From: ringabout <43030857+ringabout@users.noreply.github.com> Date: Mon, 20 Apr 2026 02:12:01 +0800 Subject: [PATCH 417/448] fixes #25718; `setLenUnit` slow (#25743) fixes #25718 This pull request optimizes sequence allocation in the Nim standard library by introducing a way to create uninitialized sequence payloads for element types that don't require zero-initialization. The changes allow for more efficient memory allocation when initializing sequences with types that have no references, avoiding unnecessary zeroing of memory.

I tried to improve `resolveFile`, which is harder because either we need to add `lib/std` to search path and all of other nested directory to `--path` in `config/nim.cfg`.

If oldLen < newLen <= capacity, it returned early without finalizing: ```nim var s = newStringOfCap(10) s.add("abc") s.setLenUninit(6) doAssert s.len == 6 # used to fail, len stayed 3 ``` This escaped `tests/stdlib/tstring.nim` because the testing routine `checkSetLenUninit` mostly resizes strings created at **exact** length/capacity, so growth usually took the reallocating branch.

The bug is specific to memory managers that use destructor injection (arc/orc); under `--mm:refc` the original code path works correctly because no destructor wrapper is injected. ## Root cause When the body of `except T as e:` is processed under ARC/ORC, the destructor injection pass injects a compiler-generated `nkHiddenTryStmt` wrapper around the handler body to call `=destroy` on `e` when it goes out of scope. That wrapper sits at the top of `p.nestedTryStmts` with `inExcept = false`. `finallyActions` (which inlines the user-finally body before a raise propagates) only inspected the topmost entry of `nestedTryStmts`. Because the wrapper has `inExcept = false`, the check short-circuited and the user's finally was never inlined. After the raise, C++'s rule that sibling catch clauses do not catch each other's throws means the surrounding `catch(...)/finally` emitted by `genTryCpp` never runs either, so the user's finally is silently dropped. ## Fix - Add an `isHidden` flag to `nestedTryStmts` entries, set to `t.kind == nkHiddenTryStmt` so compiler-injected try wrappers can be distinguished from user-written ones. - In `finallyActions`, walk past `isHidden` wrappers but stop at the first user try. If that user try is in its except branch with a finally, inline the finally body before the raise; otherwise leave the raise untouched (the raise will be caught by that user try's own except branches and the inner finally will run via normal unwinding, which is what already happens correctly under refc). Walking past wrappers fixes the `as e` case under arc/orc. Stopping at user trys preserves the existing correct behaviour for nested try/except/finally constructs (e.g. `tests/exception/tfinally.nim`'s `nested_finally`), which would otherwise see the outer finally inlined too eagerly when an inner raise is processed. ## Tests Adds `tests/exception/tcpp_handler_raise_finally.nim` covering: - `except T as e:` re-raise + outer finally - typeless `except:` re-raise + outer finally - try/finally without except (exception propagation through finally) The test runs on `--mm:arc`, `--mm:orc`, and `--mm:refc`. Locally verified on both `devel` and `version-2-2`: - `tests/exception/` — 42 PASS, 0 FAIL, 3 SKIP - `tests/destructor/` — all PASS - `tests/cpp/` — all PASS (single unrelated failure: `tasync_cpp.nim` needs the `jester` package) - `megatest` — PASS for both `--mm:arc` and `--mm:refc`, including the previously regressing `tfinally.nim`'s `nested_finally` ## Backport Tagged `[backport]` in the commit message for inclusion in `version-2-2`. --------- Co-authored-by: puffball1567 <17452514+puffball1567@users.noreply.github.com> --- compiler/ccgstmts.nim | 36 +++++++---- compiler/cgendata.nim | 7 ++- .../exception/tcpp_handler_raise_finally.nim | 61 +++++++++++++++++++ tests/exception/tcpp_imported_exc.nim | 2 +- 4 files changed, 92 insertions(+), 14 deletions(-) create mode 100644 tests/exception/tcpp_handler_raise_finally.nim diff --git a/compiler/ccgstmts.nim b/compiler/ccgstmts.nim index a80ef37efd..5ea23d1f80 100644 --- a/compiler/ccgstmts.nim +++ b/compiler/ccgstmts.nim @@ -230,7 +230,7 @@ proc blockLeaveActions(p: BProc, howManyTrys, howManyExcepts: int, isReturnStmt # Called by return and break stmts. # Deals with issues faced when jumping out of try/except/finally stmts. - var stack = newSeq[tuple[fin: PNode, inExcept: bool, label: Natural]](0) + var stack = newSeq[tuple[fin: PNode, inExcept: bool, isHidden: bool, label: Natural]](0) inc p.withinBlockLeaveActions for i in 1..howManyTrys: @@ -836,12 +836,26 @@ proc raiseExitCleanup(p: BProc, destroy: string) = p.s(cpsStmts).addGoto("LA" & $p.nestedTryStmts[^1].label & "_") proc finallyActions(p: BProc) = - if p.config.exc != excGoto and p.nestedTryStmts.len > 0 and p.nestedTryStmts[^1].inExcept: - # if the current try stmt have a finally block, - # we must execute it before reraising - let finallyBlock = p.nestedTryStmts[^1].fin - if finallyBlock != nil: - genSimpleBlock(p, finallyBlock[0]) + if p.config.exc != excGoto: + # Walk past compiler-injected `nkHiddenTryStmt` wrappers (e.g. ARC's + # destructor try/finally that wraps `except T as e:` bodies) to reach + # the user's actual try.

Additionally, it adds a new test to cover this scenario. The most important changes are: ### Compiler logic improvements * Updated the `evalTypeTrait` implementation for the `distinctBase` trait in `compiler/semmagic.nim` to properly skip all relevant type wrappers, including those with generic and static parameters, when unwrapping distinct types. This fixes incorrect handling of types like `distinct L[int, 100]`. ### Test coverage * Added a new test block for bug #25789 in `tests/metatype/ttypetraits.nim` that defines a distinct type over a generic type with a static parameter, verifies conversions, and checks that the `distinctBase` trait returns the correct type. --- compiler/semmagic.nim | 9 ++++++--- tests/metatype/ttypetraits.nim | 29 +++++++++++++++++++++++++++++ 2 files changed, 35 insertions(+), 3 deletions(-) diff --git a/compiler/semmagic.nim b/compiler/semmagic.nim index 88d7512373..397c08bf67 100644 --- a/compiler/semmagic.nim +++ b/compiler/semmagic.nim @@ -248,10 +248,13 @@ proc evalTypeTrait(c: PContext; traitCall: PNode, operand: PType, context: PSym) assert operand.kind == tyTuple, $operand.kind result = newIntNodeT(toInt128(operand.len), traitCall, c.idgen, c.graph) of "distinctBase": - var arg = operand.skipTypes({tyGenericInst}) + var arg = operand.skipTypes(skippedTypes) let rec = semConstExpr(c, traitCall[2]).intVal != 0 - while arg.kind == tyDistinct: - arg = arg.base.skipTypes(skippedTypes + {tyGenericInst}) + while true: + let distinctArg = arg.skipTypes(skippedTypes + {tyGenericInst}) + if distinctArg.kind != tyDistinct: + break + arg = distinctArg.base.skipTypes(skippedTypes) if not rec: break result = getTypeDescNode(c, arg, operand.owner, traitCall.info) of "rangeBase": diff --git a/tests/metatype/ttypetraits.nim b/tests/metatype/ttypetraits.nim index 0107f6b049..46601c1070 100644 --- a/tests/metatype/ttypetraits.nim +++ b/tests/metatype/ttypetraits.nim @@ -434,3 +434,32 @@ block: # bug #24378 type Win222[T] = typeof("foobar") doAssert not supportsCopyMem((int, Win222[int])) doAssert not supportsCopyMem(tuple[a: int, b: Win222[int]]) + +block: # bug #25789 + type + L[T; N: static int] = distinct seq[T] + EPF = distinct L[int, 100] + + var e: EPF = EPF(L[int, 100](@[1, 2, 3])) + + template classifyGeneric[T](x: T): bool = + when typeof(x) is L: + true + else: + false + + template classifyConcrete[T](x: T): bool = + when typeof(x) is L[int, 100]: + true + else: + false + + let viaConv = L[int, 100](e) + doAssert $type(viaConv) == "L[system.int, 100]" + doAssert classifyGeneric(viaConv) + doAssert classifyConcrete(viaConv) + + let viaDB = distinctBase(e, recursive = false) + doAssert $type(viaDB) == "L[system.int, 100]" + doAssert classifyGeneric(viaDB) + doAssert classifyConcrete(viaDB) From e9a0c9634e15b0bab5356547ff848d73faf11630 Mon Sep 17 00:00:00 2001 From: ringabout <43030857+ringabout@users.noreply.github.com> Date: Wed, 6 May 2026 03:05:17 +0800 Subject: [PATCH 432/448] fixes #25784; Object default field initialized with an object constructor (#25785) fixes #25784 This pull request addresses the handling of forward object types during type determination in the Nim compiler and adds new test cases to ensure correct default value initialization for objects with forward references. The main focus is to allow forward object types to remain unresolved during the initial type analysis, deferring their resolution to a later compilation phase. This helps support object constructors with default values involving forward types. **Compiler improvements:** * Updated `semObjConstr` in `compiler/semobjconstr.nim` to allow forward object types (`tyForward`) to remain unresolved during determine-type analysis. This avoids premature errors and ensures that such types are resolved later, supporting delayed field-default resolution. **Testing enhancements:** * Added new test cases in `tests/objects/mobject_default_value.nim` to verify that objects with default fields referencing forward types are correctly initialized, and that their default values are properly set. --------- Co-authored-by: Copilot <copilot@github.com> --- compiler/semobjconstr.nim | 5 ++++ compiler/semtypes.nim | 1 + tests/objects/tobject_default_value.nim | 35 ++++++++++++++++++++++++- 3 files changed, 40 insertions(+), 1 deletion(-) diff --git a/compiler/semobjconstr.nim b/compiler/semobjconstr.nim index d9317c3320..769f88b6f2 100644 --- a/compiler/semobjconstr.nim +++ b/compiler/semobjconstr.nim @@ -486,6 +486,11 @@ proc semObjConstr(c: PContext, n: PNode, flags: TExprFlags; expectedType: PType # we have to watch out, there are also 'owned proc' types that can be used # multiple times as long as they don't have closures. result.typ.incl tfHasOwned + if t.kind == tyForward and efDetermineType in flags: + # a forward object type does not error during determine-type analysis; + # it now stays unresolved long enough for the existing delayed field-default pass to resolve it after the type section finishes. + result.typ = t + return result if t.kind != tyObject: return localErrorNode(c, result, if t.kind != tyGenericBody: "object constructor needs an object type".dup(addTypeNodeDeclaredLoc(c.config, t)) diff --git a/compiler/semtypes.nim b/compiler/semtypes.nim index 4c2d84c29f..8009f7293c 100644 --- a/compiler/semtypes.nim +++ b/compiler/semtypes.nim @@ -370,6 +370,7 @@ proc semFieldDefault(c: PContext; owner, expectedType: PType; field: PNode): PTy propagateToOwner(owner, result) proc semDelayedFieldDefault(c: PContext; owner, expectedType: PType; field: PNode) = + resetSemFlag(field[^1]) fitDefaultNode(c, field[^1], expectedType) propagateToOwner(owner, field[^1].typ.skipIntLit(c.idgen)) diff --git a/tests/objects/tobject_default_value.nim b/tests/objects/tobject_default_value.nim index 5b0a5cd8e6..69e35bf826 100644 --- a/tests/objects/tobject_default_value.nim +++ b/tests/objects/tobject_default_value.nim @@ -833,4 +833,37 @@ proc overloaded[T: object](x: T) = var v: typeof(val) overloaded(v) -overloaded(Thing()) \ No newline at end of file +overloaded(Thing()) + +block: + type + Foo = object + x = Bar() + + Bar = object + x: int + + var f = Foo() + doassert f.x.x == 0 + +block: + type + Foo = object + x = Bar(x: 55) + + Bar = object + x: int + + var f = Foo() + doassert f.x.x == 55 + +block: + type + Bar = object + x: int + + Foo = object + x = Bar() + + var f = Foo() + doassert f.x.x == 0 From df7a114d7ac3afa5ea7560617539dd9b8211f036 Mon Sep 17 00:00:00 2001 From: Andreas Rumpf <rumpf_a@web.de> Date: Wed, 6 May 2026 08:41:59 +0200 Subject: [PATCH 433/448] IC: use the newer nif27 format (#25792) --- compiler/deps.nim | 11 ++++++++++- doc/ic.md | 2 +- koch.nim | 4 ++-- 3 files changed, 13 insertions(+), 4 deletions(-) diff --git a/compiler/deps.nim b/compiler/deps.nim index 116c0ebdf3..cfe0f0975f 100644 --- a/compiler/deps.nim +++ b/compiler/deps.nim @@ -488,10 +488,19 @@ proc generateBuildFile(c: DepContext): string = let exeFile = changeFileExt(c.nodes[0].files[0].nimFile, ExeExt) b.addTree "do" b.addIdent "nim_nifc" - # Input: .nim file (expanded as argument) and .nif file (dependency) + # Input: .nim file (expanded as argument) b.addTree "input" b.addStrLit mainNif b.endTree() + # Also depend on the semmed .nif files of the main module and all its + # dependencies. nifmake's topological sort orders nodes by depth; without + # these inputs the nim_nifc node sits at depth 1 (no recognized inputs) + # alongside the nifler nodes and runs *before* the nim_m steps that + # produce the .nif files it needs to read. + for node in c.nodes: + b.addTree "input" + b.addStrLit c.semmedFile(node.files[0]) + b.endTree() b.addTree "output" b.addStrLit exeFile b.endTree() diff --git a/doc/ic.md b/doc/ic.md index 9027f8ba63..9fd7b55d2b 100644 --- a/doc/ic.md +++ b/doc/ic.md @@ -33,7 +33,7 @@ The text representation is particularly valuable for debugging and introspection Each ``.nim`` module produces its own ``.nif`` file during compilation.

After: `match("CAFÉ", peg"\i café")`, `match("Café", peg"\i café")`, and `findAll` over mixed-case occurrences pass. `std/pegs` documents `useUnicode = true` as proper UTF-8 support, and quoted terminals already preserved the same bytes; this makes bare terminals consistent with that path.

This breaks when a collection element type has a `$` that returns an empty string: `result.len` stays at 1 after the first item contributes nothing, so the separator is never inserted for subsequent items. ```nim import std/deques type Test = object proc `$`(x: Test): string = "" echo [Test(), Test()].toDeque # prints [] — expected [, ] ``` ## Fix Replace the length check with an explicit `first` flag in all affected modules: `deques`, `heapqueue`, `lists`, `critbits`, and `strtabs`. ## Tests Regression tests added to `tdeques`, `theapqueue`, and `tlists` using a local type whose `$` returns `""`. All three test files pass with `nim c -r`. ## Notes I work with Claude as a co-processor. I'm 56, came to programming late, and this is genuinely how I learn and contribute. I understand what I'm submitting, but I didn't write it alone.

It refactors the move operation logic to better support custom hooks, adds new tests for edge cases, and ensures that the `move` operation is safer and more predictable. **Move semantics and `=wasMoved` handling:** * Refactored the move operation in `compiler/ccgexprs.nim` by introducing helper procs (`canGenMoveCall`, `genMoveCall`, `genWasMovedCall`, `genMoveWithWasMoved`) to better handle cases with user-defined `=wasMoved` hooks, especially for generics and C++ interop. The logic now distinguishes between simple assignments and when to call custom hooks, improving correctness and maintainability.
