fix: Handle GitHub API rate limiting - #1024
JH-lawliet wants to merge 9 commits into
Conversation
Rate-limited 403 responses were treated as release data: curl lacked -f,
so the paginated lookup burned up to 20 API calls and reported a misleading
not-found error. GitHub empty pages are pretty-printed "[\n\n]", which the
byte-exact "[]" check never matched; pagination now stops on any blank
array. Multi-MB bodies no longer use ${var//[[:space:]]/} (bash pattern
substitution), which hung on real responses; an anchored regex checks for
an empty page instead.
Fixes antonbabenko#1023

- Around line 58-59: Update the HTTP error handling around the `http_code` check
so HTTP 429 remains a rate-limit error, while HTTP 403 is reported as a
rate-limit error only when response headers or the GitHub error message confirm
rate limiting; report other 403 responses as access failures.

CodeRabbit flagged that every 403 was reported as a rate limit, but GitHub also returns 403 for permission and SSO failures, where telling the user to set GITHUB_TOKEN is misleading (they may already have one). Keep 429 and 403s whose body mentions "rate limit" on the rate-limit diagnostic; report any other 403 as a generic access denied HTTP error. Assisted-by: opencode:mimo-v2.6-flash-free opencode

I guess we use common::colorify function to throw messages and errors. Please follow this pattern.
Errors are red, warnings are yellow, notices and regular messages are green if I'm not mistaken.

Replace all echo with common::colorify as decribed above
Apply @yermulnik's review on the rate-limit handling: compare HTTP codes numerically (-eq/-ne), fold the 403 rate-limit check into the [[ ]] condition with tr instead of a grep pipeline, reword the GITHUB_TOKEN hint, report Forbidden instead of access denied, drop the redundant empty_page_re variable, and capitalize Failed. Route every touched diagnostic through common::colorify (copied from hooks/_common.sh; install scripts are standalone and cannot source the hooks copy): errors red, the rate-limit hint yellow.

Hi @yermulnik, I have refactored the code according to the comments, could you review again? 🙏 |

Appreciate your time @JH-lawliet and apologies for the confusion I introduced in previous round of review.
The feature LGTM though.
@MaxymVlasov Would you please join the review when you have a chance? Thanks.
The tools/install is not interactive human-facing output, so the colorify wrapper is reverted to plain echo (stderr preserved). The message wording and -eq/-ne comparisons from the earlier review round are kept. Also applies two more review nits: move '|| true' outside the command substitution, and use '[[ ! $asset_url ]]' instead of -z. Assisted-by: opencode:mimo-v2.6-flash-free opencode

Can you please explain why just for the word ' (Forbidden) ' we need a whole ' if '? It does not provide any useful info, IMO, as it's literally what HTTP 403 means

Hi @MaxymVlasov.
For the common::colorify replace, I just want to confirm that do you mean we need to copy the colorify function from the hooks/_common.sh? Because previously @yermulnik mistook the current tools/install/_common.sh for hooks/_common.sh and left the colorify comment above. The discussion can be found here
The /tools/install/ need no color output as it's not an interactive human facing output I guess

You are right. I think there was a version that I added detailed description for 403 response, but it was removed. I will remove this redundant Forbidden to make it more simple.

I see. Let me quickly move colorify to a separate file so it can be easily imported everywhere

Hi @MaxymVlasov, quick note on the two extra files in this update:
tools/install/_common.sh now sources common::colorify from hooks/_logging.sh instead of plain echo per your review.
However, the install scripts run standalone in the Docker builder — where only tools/install/ is copied to /install/ . So I added COPY hooks/_logging.sh /hooks/_logging.sh to the Dockerfile, plus !hooks/_logging.sh to .dockerignore (which excludes everything outside its allowlist) so the file is actually present in the build context. Without the .dockerignore line the build fails with /hooks/_logging.sh: not found. I have verified via the fork CI docker build, pls review when you are available🙏.
Source common::colorify from hooks/_logging.sh (extracted in antonbabenko#1026) instead of plain echo: errors in red, GITHUB_TOKEN hint in yellow. Collapse the redundant 403 Forbidden branch into the generic HTTP error, per maintainer review. Copy hooks/_logging.sh into the Docker builder image so /install/_common.sh can source it during build. Assisted-by: opencode:muse-spark-1.3-contributor-free opencode
The .dockerignore allowlist excluded hooks/, so COPY hooks/_logging.sh failed with "/hooks/_logging.sh: not found". Whitelist the single shared logging helper instead of the whole hooks/ directory. Assisted-by: opencode:muse-spark-1.3-contributor-free opencode
The repo-relative path already resolves to /hooks/_logging.sh in the Docker builder. Assisted-by: opencode:muse-spark-1.3-contributor-free opencode

common::gh_api_gettotools/install/_common.sh: it reads the HTTP status alongside the body and fails fast instead of feeding error payloads into the release-page loop — HTTP 429, and HTTP 403 whose body confirms rate limiting, get a rate-limit error that points atGITHUB_TOKEN; any other HTTP 403 is reported as a generic access denied failure; remaining non-200 responses and curl failures become explicit HTTP/transport errors.[\n\n]— the byte-exact[]check never fired, so every lookup burned the full 20 pages.${var//[[:space:]]/}full-body whitespace strip (which stalls on multi-MB release pages) with an anchored empty-page regex.Why
Rate-limited 403 responses were treated as release data: curl lacked -f,
so the paginated lookup burned up to 20 API calls and reported a misleading
not-found error. This change handles the GitHub Rate-limited error scenario: fail fast with an error pointing at GITHUB_TOKEN instead of burning the remaining quota and throwing a misleading not-found error.
