The first commit reverts the revert of #23787. The second fixes lambdalifting in convolutedly nested closures/closureiters. This is considered to be the reason of #24094, though I can't tell for sure, as I was not able to reproduce #24094 for complicated but irrelevant reasons. Therefore I ask @jmgomez, @metagn or anyone who could reproduce it to try it again with this PR. I would suggest this PR to not be squashed if possible, as the history is already messy enough. Some theory behind the lambdalifting fix: - A closureiter that captures anything outside its body will always have `:up` in its env. This property is now used as a trigger to lift any proc that captures such a closureiter. - Instantiating a closureiter involves filling out its `:up`, which was previously done incorrectly. The fixed algorithm is to use "current" env if it is the owner of the iter declaration, or traverse through `:up`s of env param until the common ancestor is found. --------- Co-authored-by: Andreas Rumpf <rumpf_a@web.de>
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.
