fix: guard CLAUDE_CODE_MAX_RETRIES against non-numeric env values - #2172
fix: guard CLAUDE_CODE_MAX_RETRIES against non-numeric env values#2172Ricardo-M-L wants to merge 2 commits into
Conversation
getDefaultMaxRetries() used bare parseInt() which returns NaN for non-numeric input (e.g. CLAUDE_CODE_MAX_RETRIES=abc). The retry loop condition 'attempt <= NaN + 1' is always false, so the entire retry machinery silently skipped — the first API error caused an immediate fatal failure instead of retrying. Fix: validate the parsed value with Number.isNaN and a lower bound of 0, log a debug message when falling back, and keep DEFAULT_MAX_RETRIES (10) as the safe default. Zero is accepted as a valid explicit value (disable retries). Closes a footgun where a typo in the env var (extra whitespace, trailing garbage from shell interpolation) completely disables retries with no visible warning.

Clear inherited environment state before each test.
afterEach runs only after a test. If CLAUDE_CODE_MAX_RETRIES is set when the test file starts, the first test imports that value and can fail instead of testing the default path.
Delete the variable in beforeEach, and restore the original value in afterEach if other tests depend on it.
As per path instructions, isolate global/env/config state in tests.

Reject whitespace-only retry values.
When CLAUDE_CODE_MAX_RETRIES contains only whitespace, getDefaultMaxRetries() accepts Number('') as 0 and disables retries instead of returning DEFAULT_MAX_RETRIES. Reject empty trimmed values and add a regression test for ' '.

I found issues that need to be addressed before this is ready.
Merge readiness
- [P1] Rebase onto current
mainand resolve the retry-module conflicts before merge
src/services/api/withRetry.ts:809
This head is based on4830d6f7, while the live target is8db88306; GitHub reports the PR asCONFLICTINGwith merge stateDIRTY. The target branch has independently changed both the retry implementation and its test harness, so resolving this mechanically could restore behavior thatmainhas since replaced. Rebase or reconstruct this narrow fix on currentmain, preserve the current retry configuration and test-helper contracts, then request review of the resolved diff.
Findings
-
[P2] Treat whitespace-only retry settings as invalid rather than as an explicit retry disable
src/services/api/withRetry.ts:811
The configuration is validated after coercion instead of before it: a value such asCLAUDE_CODE_MAX_RETRIES=" "is truthy at the outer guard,trim()changes it to"", and JavaScript converts that empty string to numeric0. Since zero is intentionally valid, the non-negative-integer check accepts the malformed value and returns it without logging the fallback.getMaxRetries()passes that zero towithRetry, whose loop permits only the initial request (attempt <= maxRetries + 1), so transient errors that should receive the default retry budget fail immediately.Address the root cause by distinguishing a non-empty lexical integer from a number produced by coercion: validate the trimmed string is non-empty before numeric conversion (and keep rejecting partial, fractional, negative, and non-finite input), then convert and apply the existing integer/range check. Preserve literal
"0"as the documented explicit opt-out. Add a regression test for whitespace-only input that verifies both the returned default and, ideally, the retry-loop outcome for a retryable first failure, so this parser-to-consumer contract cannot silently regress.

Fix silent retry disable when CLAUDE_CODE_MAX_RETRIES contains non-numeric values (e.g. 'abc'). parseInt returns NaN, causing the retry loop to never execute.
