Support .tool-versions pins - #68
Conversation
#67 bumps pre-commit 4.5.1 to 4.6.2 in .tool-versions, and the assertion refused it on both counts: the file was not in the allowlist, and its `<tool> <version>` form has no prefix for the version matcher to anchor on. The allowlist gains the file. The line form is matched whole-line rather than by prefix, because a lookbehind of variable width is not allowed and "the word after a space" would match most of a workflow file, so normalize now takes the path and uses that pattern for that file only. The tool name is still the prefix, kept and compared, so swapping it or adding a line is refused as before. All four open bot pull requests pass now, and there are twenty-four tests.

* Bound the steps that reach the network `Install xmlstarlet` hung for the entire twenty minute job budget on #68, twice in a row, while every step after it was skipped. It had no limit of its own, so one stalled apt mirror spent the whole suite, and the only report possible was that the run did not finish. The 25 minute timeout seen the day before was very likely the same thing. That step now has a six minute bound, three attempts, and explicit apt timeouts, which are what make a stall fail fast enough for a retry to be worth having. The other three steps that reach the network, the podman archive install, setup-python and the pip install, get bounds too. The steps that only touch local files are left alone: they cannot hang on a mirror, and a limit on each would be noise. The job cap stays the binding limit and is meant to. Step limits sum to well over an hour because each allows for its own worst case, and what they buy is a single hung step failing on its own rather than taking the suite with it. * Bound every step, sized from a measured run Every step in the suite job now carries its own limit, and the existing ones are resized. They were guesses; these come from the steps of a passing run: xmlstarlet 36s, podman 180s, seed 69s, pull 54s, start 78s, wait 118s, wire 47s, tests 270s, teardown 15s, everything else under 10s Each limit is roughly two to three times what its step actually takes, with more slack where the duration depends on the network or on the stack coming up. The worst case for a single stall drops from twenty minutes to nine, and for most steps to two or three. The job cap stays at 20, and the comment claiming otherwise is corrected while I am here. That number came from run level timestamps reading 11 or 12 minutes; the steps of a passing run sum to 14.8, so 20 is about a third of headroom rather than two thirds. Cutting it further would start failing honest runs.

Match exact allowlisted paths.
The validation at Line [178] uses tuple-prefix matching. After adding .tool-versions, paths such as .tool-versions-malicious and .tool-versions/child also pass the allowlist. A tool==1 to tool==2 change in such a path can pass through the generic VERSION normalization. Match exact filenames separately from directory prefixes, and use an exact .tool-versions check in the path-specific branch.

asdf .tool-versions configuration format multiple versions inline comments official documentation
💡 Result:
The.tool-versions configuration file used by asdf has specific behaviors regarding syntax and version handling. File Format and Inline Comments Official documentation defines the.tool-versions file as a text file used to specify tool versions [1][2]. While official documentation does not explicitly detail comment support, the underlying implementation and community-identified behavior indicate that lines beginning with # are typically ignored by asdf commands such as asdf install [3]. However, inline comments (comments placed on the same line after a version string) are not supported and will likely cause parsing errors, as the entire line is often treated as the version configuration [4][3]. Multiple Versions You can specify multiple versions for a single tool in a.tool-versions file by separating them with spaces [1][2]. The intention, as stated in the official documentation, is that these versions act as a list where asdf falls back from the first version to the next if a specific version is not available [1][2]. Note: There are reported inconsistencies and community discussions regarding how asdf processes these multi-version lists. Some users have observed that the behavior may not always strictly adhere to a "first-available" fallback logic, with some reports suggesting that the most recently released version or other sorting mechanisms may influence the outcome regardless of the order defined in the file [5]. Summary of Supported Version Formats: - Exact version: e.g., 10.15.0 [1][2] - Ref (tag/commit/branch): e.g., ref:v1.0.2-a [1][2] - Path (local source): e.g., path:~/src/elixir [1][2] - System: system (uses the version installed on the OS) [1][2]

Support multiple versions in .tool-versions entries. TOOL_VERSION_LINE matches only one version token, so a line such as nodejs 20.0.0 18.0.0 remains unnormalized and a version-only update is refused. Parse one tool followed by one or more version tokens, preserve the tool and token count, and add a regression test.

This is the third format I have had to add after the fact, following lazylibrarian's
