调研方向
Start by reading the changes in #7825 and #7826, then inspect the tool-versions resolution paths and the follow-ups to #7887. Measure which resolution paths and parsing costs affect actual install-tool requests before choosing an optimization; done means reducing unnecessary resolution cost while preserving fresh releases and the documented fallback behavior.

描述
What would you like containerbase to do?
Keep the version resolution through the tool-versions data cheap, as hosted Renovate runs install-tool millions of times a day and every run starts without a cache.
Costs per run since #7825 and #7826, for tools without their own resolver (exact versions read nothing):
latestor a missing version: one HTTP request to the online tool-versions data, tens to hundreds of ms, up to the 30 s timeout when the network stalls, plus an embedded read as fallback- a partial version: one embedded read and parse, plus the HTTP request unless the embedded data lists the version
- an embedded read:
JSON.parseand the zod check of one<tool>.json, below 0.5 ms typical, ~8 ms for the largest file (renovate.json)
Ideas
- skip the online lookup when the embedded data is recent enough, needs the release time of the data (containerbase/tool-versions#149)
- measure the zod check at runtime again and drop it if it matters (the image build already checks the data)
- check which versions Renovate requests from
install-tool(exact, partial orlatest) to know which paths matter - measure the cost of the follow-ups of #7887 once more tools resolve through the data
- any cache of the online data that outlives one resolve (per process, or on disk like
HttpService.download()) needs an expiry time, so long running processes pick up new releases; todaygetJson()doesn't cache and theToolVersionsServicecache only lasts one resolve - warn when the
v1format isdeprecated(with itsremovalDate) in the rootindex.json; the online lookup fetchesv1/<tool>.jsondirectly and after a removal would silently fall back to the embedded data on the 404. Not on every run, eg. only after a 404 or at most once a day
