Copying StackTraceEntry instances when nimStackTraceOverride is defined breaks the link between a cstring field that's supposed to point at another string field in the same object. Sometimes, the original object is garbage collected, that memory region reused for storing other strings, so when the StackTraceEntry copy tries to use its cstring pointer to construct a traceback message, it accesses unrelated strings. This only happens for async tracebacks and this patch prevents that by making sure we only use the string fields when nimStackTraceOverride is defined. Async tracebacks also beautified slightly by getting rid of an extra line that was supposed to be commented out, along with the corresponding debugging output. There's also a micro-optimisation to avoid concatenating two strings just to get their combined length.
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.
cmd
Specifies the Nim command to use for compiling the test.
There are a number of variables that are replaced in this spec option:
$target- the compilation target, e.g.c.$options- the options for the compiler.$file- the filename of the test.$filedir- the directory of the test file.
Example:
discard """
cmd: "nim $target --nimblePath:./nimbleDir/simplePkgs $options $file"
"""
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. It includes a C
client and platform specific build files for manual compilation.
