`nim c --ic:on` could not compile anything that reached `std/tempfiles`:
lib/std/tempfiles.nim(115, 38) Error: type mismatch
Expression: initRand()
Expected one of: [1] proc initRand(seed: int64)
That is `std/random`. It declares `proc initRand(): Rand` WITHOUT a `*`
and then, forty lines later, `since (1, 5, 1): export initRand`.
Two mechanisms make a symbol importable and the writer only knew one.
`sfExported` is the `*` on the declaration; `semExport` instead calls
`reexportSym`, which adds the symbol to the module's interface table and
sets no flag. `writeSymDef` decided the NIF `x` marker — "importable as a
bare identifier" — from `sfExported` alone, so a symbol exported the
second way shipped as private and its importer reported an undeclared
identifier. Nothing about this is IC-specific in the source; it is
ordinary stdlib code that classic compilation accepts.
So ask the interface too: `reexportedLocalSyms` collects the symbols a
module defines that reached its interface without the flag, and they get
the marker. Symbols that are genuinely private still do not — the
regression test's sibling case (`proc g()`, never exported) is still
rejected under both `--ic:on` and `--ic:off`.
This was found by pointing `--ic:on` at Atlas, which is now the first
sizeable third-party program it builds. `nim c --ic:off` and `--ic:on`
produce the same working binary from the same 209-module closure.
ic 41/41 (the new test is the 41st), `koch boot -d:release` equal
executables.
This directory contains the test cases.
Each test must have a filename of the form: t*.nim
Note: Testament is only aware of tests under a directory (eg tests/foo/) and will ignore
top-level tests like tests/tbar.nim.
Specs
Each test can contain a spec in a discard """ ... """ block.
Check out the parseSpec procedure in the specs module for a full and reliable reference
action
Specifies what action this test should take.
Default: run
Options:
compile- compiles the module and fails the test if compilations fails.run- compiles and runs the module, fails the test if compilation or execution of test code fails.reject- compiles the module and fails the test if compilation succeeds.
There are certain spec keys that imply run, including output and
outputsub.
Categories
Each folder under this directory represents a test category, which can be
tested by running koch tests pcat <category> (or cat to avoid parallel
testing, which is slower).
The folder dll contains simple DLL tests.
The folder realtimeGC contains a test for validating that the realtime GC
can run properly without linking against the nimrtl.dll/so.
