Raka Hourianto 5eb96d40ee nre: fix replacement string parser OOB access, numeric refs, and unterminated named refs (#25560)
1. A trailing `$` at the end of a replacement string could read out of
bounds via `how[i + 1]`; this now raises `ValueError` instead.

2. Numeric capture parsing used `id += (id * 10) + digit` instead of `id
= (id * 10) + digit`, so multi-digit refs were parsed incorrectly (e.g.
`$12` resolved as capture 13 instead of 12).

4. Unterminated named replacement syntax (e.g. `${foo)` is now rejected
with ValueError instead of being accepted and parsed inconsistently.

Found and fixed by GPT 5.3 Codex.

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.
