`unapplyBlockContext` reset `inEnforcedGcSafe` and
`inEnforcedNoSideEffects` to false whenever a `{.cast(gcsafe).}` or
`{.cast(noSideEffect).}` block ended. When such a block is nested inside
another block of the same cast, the inner block's exit switched
enforcement back on for the rest of the enclosing block, so statements
lexically inside the outer cast were rejected.
The fix saves both flags in `PragmaBlockContext` when the block context
is created and restores the saved values on exit. That matches how every
other piece of block state there (`locked`, `exc`, `tags`, `forbids`) is
already handled; these two bools were the only ones reset to a constant
instead of restored.
No change for non-nested blocks: entering from the non-enforced state
saves false, so exit still clears the flag. A statement after the outer
block is still rejected as before.
Test covers nested `cast(gcsafe)` and nested `cast(noSideEffect)`.
`tests/effects` passes unchanged (49/49, same as stock).
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.
