- Handle io.ReadAll error on error body read (client.go:265)
- Remove unused State field from commitStatusResponse (pr.go)
- Guard via slice access in defaultCheckRedirect (client.go:117)
- Move GetFileContentAtRef from pr.go to files.go (logical home)
Sonnet MINOR #1: Stop timer after <-timer.C fires for idiomatic cleanup.
Sonnet MINOR #2: Document that empty array from contents API is valid (empty dir).
Sonnet MINOR #3: Document that GetPullRequestFiles returns nil for no files.
Sonnet NIT #4: Strengthen SetHTTPClient/SetRetryBackoff docs to clarify test-only intent.
Sonnet NIT #5: Document GetCommitStatuses fail-fast behavior.
Sonnet NIT #6: Document double-slash collapsing in escapePath.
Security MINOR #1: Document redirect policy responsibility when providing custom client.
Security MINOR #2: Reduce maxErrorBodyBytes from 64KB to 4KB to limit sensitive data exposure.
- SetHTTPClient(nil): preserve CheckRedirect auth-stripping policy
instead of restoring a plain http.Client that loses cross-host
protection.
- Authorization header: add comment documenting why Bearer scheme is
correct (OAuth2 standard, works for both classic PATs and
fine-grained tokens).
- Retry-After parsing: support HTTP-date format (RFC 7231) in addition
to integer seconds. GitHub only sends integers today, but the
implementation is now spec-compliant.
- escapePath dot-segment removal: document the behavior in public API
doc comments for ListContents and GetFileContentAtRef so callers are
aware without reading the internal helper.
- Remove redundant timer.Stop() after timer fires (Sonnet #1, GPT #2)
- Remove unused TotalCount field from checkRunsResponse (Sonnet #2)
- Improve escapePath doc comment to explain deliberate silent stripping (Sonnet #3)
- Fix ListContents to handle both array (directory) and object (single file)
responses from GitHub Contents API (GPT #3)
- Add HTTPS enforcement: refuse to send credentials over non-HTTPS URLs
unless AllowInsecureHTTP() option is passed (Security #1)
- Replace constant-value test with actual behavior test for response
body limiting (Sonnet #6)
- Run gofmt for consistent formatting (Sonnet #4)
- Add tests for HTTPS enforcement and ListContents single-file handling
- Add User-Agent header to all requests (gpt-review-bot)
- Limit successful response body to 10 MiB via io.LimitReader (security-review-bot)
- Add CheckRedirect to strip Authorization on cross-host redirects (security-review-bot)
- Fix decodeBase64Content to strip both \r and \n (gpt-review-bot)
- Document that transport errors are not retried (sonnet-review-bot)
- Update package doc to reflect current scope (no review submission yet)
- Add tests for User-Agent, empty-token auth skip, CRLF base64, CheckRedirect
- Fix Retry-After slice mutation: copy c.RetryBackoff before modifying
to prevent permanent mutation of the shared slice (sonnet#1, security#1)
- Cap Retry-After to 120s maximum to prevent excessive sleeps (security#2)
- Guard auth header: only set Authorization when token is non-empty (gpt#2)
- Fix GetFileContent doc comment to match actual behavior (sonnet#3, gpt#1)
- Remove dead 'in_progress/queued' case in mapCheckRunStatus (sonnet#4)
- Add testing.Short() guard to slow retry test (sonnet#5)
- Reject dot-segments in escapePath to prevent path traversal (security#3)
- Add regression tests for non-mutation and escapePath safety
Implement the GitHub API client with PRReader and FileReader interface
conformance for both github.com and GitHub Enterprise.
New files:
- github/client.go: Client struct, NewClient with configurable base URL,
HTTP helpers with 429 retry and Retry-After support
- github/pr.go: GetPullRequest, GetPullRequestDiff (per-request Accept
header), GetPullRequestFiles (paginated, populates Patch field),
GetFileContentAtRef (base64 decode), GetCommitStatuses (merges commit
statuses + check runs with conclusion mapping)
- github/files.go: GetFileContent (delegates to GetFileContentAtRef),
ListContents, escapePath, decodeBase64Content helpers
Type changes:
- vcs/types.go: Add Patch field to ChangedFile struct
Tests cover: happy path, 404, 401, 429+retry, malformed response,
pagination, binary files, check run conclusion mapping, base64 decoding.
Compile-time checks:
var _ vcs.PRReader = (*Client)(nil)
var _ vcs.FileReader = (*Client)(nil)
Exit criteria met:
- go test ./github/... passes (all methods)
- NewClient with empty baseURL uses https://api.github.com
- NewClient with GHE URL targets correctly
- GetFileContent delegates to GetFileContentAtRef with empty ref
- GetPullRequestFiles paginates and populates Patch field
- GetCommitStatuses merges both commit statuses and check-runs
