The new mechanism can deal with more complex scenarios such as
not nil field appearing in a non-default case object branch or
a field within a generic object that may depend on a when branch.
The commit also plugs another hole: the user is no longer able
to create illegal default values through seq.setLen(N).
New issue: since `Table[A, B]` allocates its backing storage with
`newSeq[KeyValuePair[A, B]]`, it's no longer legal to create a table
with `not nil` types used as either keys or values.
* code cleanups and feature additions
* added basic test and koch/CI integration
* make it build on Unix
* DrNim: now buildable on Unix, only takes 10 minutes, enjoy
* added basic documentation for DrNim which can also be seen as the RFC we're following
* drnim: change the build setup so that drnim.exe ends up in bin/
* makes simple floating point ranges work
* added basic float range check
* drnim: teach Z3 about Nim's range types plus code refactoring
* drnim: make unsigned numbers work
* added and fixed index checking under setLen
* first implementation of .ensures, .invariant and .assume (.requires still missing and so is proc type compatibility checking
* drnim: .requires checking implemented
* drnim: implemented .ensures properly
* more impressive test involving min()
* drnim: check for proc type compatibility and base method compatibility wrt .requires and .ensures
* testament: support for 'pattern <directory>
* koch: uses new <directory> feature of testament
* drnim: added tiny musings about 'old'
* Make testament work with old SSL versions
* koch: add support for 'koch drnim -d:release'
* drnim: preparations for the param.old notation
* new minor feature: macros for proc types, to be documented
* Finished the implementation and added tests
* [skip ci] Describe the new custom pragmas in the manual and the changelog

* workflows/ci_docs: fix docs publishing
It turns out that github.ref is the full ref name, so we have to be a
bit more specific.
See https://developer.github.com/v3/activity/events/types/#pushevent
Also fixed a silly typo :)
* workflows/ci_docs: run CI when there are changes to the workflow
* Unwind just the "pseudorandom probing" (whole hash-code-keyed variable
stride double hashing) part of recent sets & tables changes (which has
still been causing bugs over a month later (e.g., two days ago
https://github.com/nim-lang/Nim/issues/13794) as well as still having
several "figure this out" implementation question comments in them (see
just diffs of this PR).
This topic has been discussed in many places:
https://github.com/nim-lang/Nim/issues/13393https://github.com/nim-lang/Nim/pull/13418https://github.com/nim-lang/Nim/pull/13440https://github.com/nim-lang/Nim/issues/13794
Alternative/non-mandatory stronger integer hashes (or vice-versa opt-in
identity hashes) are a better solution that is more general (no illusion
of one hard-coded sequence solving all problems) while retaining the
virtues of linear probing such as cache obliviousness and age-less tables
under delete-heavy workloads (still untested after a month of this change).
The only real solution for truly adversarial keys is a hash keyed off of
data unobservable to attackers. That all fits better with a few families
of user-pluggable/define-switchable hashes which can be provided in a
separate PR more about `hashes.nim`.
This PR carefully preserves the better (but still hard coded!) probing
of the `intsets` and other recent fixes like `move` annotations, hash
order invariant tests, `intsets.missingOrExcl` fixing, and the move of
`rightSize` into `hashcommon.nim`.
* Fix `data.len` -> `dataLen` problem.
* #13806 - first call sysctl with a null buffer to get the length, then alloc buffer and call again
* Use csize_t rather than csize
* Suggestions from @Clyybber

* workflows/ci_docs: publish documentation to Github Pages
This should be a complete replacement for our current Travis CI setup.
* workflows/ci_docs: run docgen upon modification to the css on push
So that any changes regarding the stylesheets would be reflected on the
published docs.
* workflows/ci_docs: build the compiler in release mode
* workflows/ci_docs: set branch name for the generated docs
This makes the "Source" links work correctly.
* workflows/ci_docs: run docgen on windows and osx too
Only deploy the Linux-generated version.
* workflows/ci_docs: cache csources compiler
This should cut the time spent building csources, which is about 1-2mins
depending on OS.
* stacktraces can now show custom runtime msgs
* improve tests/stdlib/tstackframes.nim
* fix test for --gc:arc
* test --stacktraceMsgs:on and --stacktraceMsgs:off
* --stacktracemsgs:off by default
* osproc: move fork-based code path under the when conditional
* osproc: avoid using the environ global on Haiku
* osenv: import environ from stdlib.h on Haiku
Haiku's environ is declared in `<stdlib.h>` by default, differing from
POSIX and/or Linux. Import it from there to avoid collision with anyone
importing `<stdlib.h>` from Nim.
* koch boot --gc:arc now passes the nim stage
... but generates invalid C code
* Move it closer to where its used
* Try something else
* Poor mans var
* Use UncheckedArray instead
These constants were defined as `cint`. They can be huge on certain
systems, such as Haiku, and trigger out-of-bounds errors in
asyncdispatch.
Ref #13764.
* Fix typeSym.getImpl for ref types
* Fix a codegen issue affecting the test suite of nim-beacon-chain
* Fix tests/stdlib/tjsonmacro
To understand the fix better it may help to take a look
at the history of the replaced code.
The nil check that is removed in this commit was introduced
in another fix that failed to identify the root cause of the
issue - namely that we allow an object type to exist for which
no ast is present:
https://github.com/nim-lang/Nim/pull/9601/files
The original intention of the code is more obvious here:
https://github.com/nim-lang/Nim/pull/9538/files
