harden(error-lifecycle): snapshot allocator, enforce teardown guard, remove NOLINT, localize tidy #46
Conversation
…NOLINT; local tidy override What and why - Prevent double-free/UAF by making contexts registries, not owners. - Snapshot allocator in gitledger_error_t so release is safe post-context teardown. - Enforce lifecycle: in debug, abort if context has live errors; in release, refuse to destroy and log. - Remove all NOLINT and refactor to satisfy clang-tidy: split teardown helpers, safe snprintf+fwrite logging, named constants. - Restore global .clang-tidy and localize the bugprone-easily-swappable-parameters disable under libgitledger/core/ to account for C callback signatures. - Reaffirm host execution guard in AGENTS.md. Validation - Format + clang-tidy: clean locally. - Unit tests + ASAN/UBSAN + TSAN: green locally (macOS leak detection disabled as unsupported). Follow-ups - Add a unit test to assert teardown refusal semantics. - Optional single-shot structured diagnostic for lifecycle violations. No rebase, no amend, no force. Logged activity before committing.

54-102: ---The snprintf naming violation is real, but the suggested fix won't compile in C.
You're absolutely right that the function breaks the snprintf contract—returning 0 on truncation instead of the required length is a semantic disaster. But your diff is completely broken: C does not support lambdas. That's C++11 syntax. This is a C file.
Here's what actually needs to happen:
- The semantic violation is valid: current code returns 0 on truncation; snprintf returns the size that would have been written.
- Existing tests are garbage—they don't test truncation, n=0, or small buffers at all.
- You need a proper C implementation that:
- Computes the required length upfront (either inline or via a helper that doesn't use lambdas)
- Returns that length regardless of truncation
- Only writes to the buffer when space exists
- NUL-terminates on truncation
Write a correct C-only fix, add edge-case tests for n=0 and n=5 truncation, and verify the buffer is NUL-terminated even when truncated.

126-137: STOP. Build configuration is corrupted—verify C standard target immediately.Git history shows three C17 commits (
a1884a1,c4e498d,3abc1c2), the activity log claims C17 was set on 2025-10-23, butmeson.buildline 3 andCMakeLists.txtline 29 both declarec_std=c99/-std=c99.This mismatch is a problem:
- If C99 is intentional: The review comment is wrong.
##__VA_ARGS__is already portable for C99; no change needed.- If C17 is intentional (per git history): The build files are broken, AND the review comment's concern about stricter preprocessors is legitimate. Apply the portable macro pattern.
Your task: Verify and reconcile. Did the C standard regress to C99, or are the build files stale? Once you confirm the actual target, the macro fix decision becomes clear.
ACTIVITY.log.jsonl (1)
75-76: Validation passed; lines 75–76 are append-only compliant.The activity log validator confirmed schema compliance, and both entries at lines 75–76 are well-formed with ISO 8601 timestamps, all required keys present, and chronological ordering intact. The corrective entry at "2025-10-25T15:27:09Z" documents the timestamp fix as part of the Code Rabbit review remediation. No append-only violation detected in the current state.

130-145: Finally fixed the json_cache data race. This is the right CAS/exchange pattern.Atomic uintptr_t, exchange on invalidate/free, CAS to publish, and snapshot allocator for frees — this eliminates the double-free/leak races.

671-691: Chain-release logic is sound. Don’t get clever and “recursive” here.Iterative release of cause-on-zero is correct and avoids deep recursion. Good.
Add a test asserting that releasing the top error drops exactly one ref from each cause and only frees the chain when each reaches zero.

138-141: -nostdlib not actually applied to executables because add_nostdlib() respects a dead option.Lines 138–141 call
add_nostdlib(), which does NOTHING becauseGITLEDGER_USE_NOSTDLIBdefaults to OFF. This means your executables link WITH libc by default, violating the mandatory policy. Replace the function calls with direct link option assignments:- add_nostdlib(gitledger_version_test) - add_nostdlib(gitledger_tests) - add_nostdlib(mg-ledger) - add_nostdlib(gitledger_error_test) + if(NOT MSVC) + target_link_options(gitledger_version_test PRIVATE -nostdlib) + target_link_options(gitledger_tests PRIVATE -nostdlib) + target_link_options(mg-ledger PRIVATE -nostdlib) + target_link_options(gitledger_error_test PRIVATE -nostdlib) + endif()Or define
add_nostdlib()correctly:function(add_nostdlib target) if(NOT MSVC) target_link_options(${target} PRIVATE -nostdlib) endif() endfunction()Then the calls at 138–141 actually WORK. As per coding guidelines.
28-36: PROJECT_WARNING_FLAGS violates guidelines: extra flags and -nostdlib misplaced.The guidelines mandate exactly:
-Wall -Wextra -Werror -pedantic -std=c99 -nostdlib -Wno-fun. Your line 31 adds three flags NOT in the spec:-Wshadow,-Wconversion,-fvisibility=hidden. These are extra strictness you're imposing unilaterally. Strip them out and leave only what the policy requires. Also,-nostdlibis a linker flag, not a compile flag—it doesn't belong in PROJECT_WARNING_FLAGS at all; move it to executables' link options only.- set(PROJECT_WARNING_FLAGS -Wall -Wextra -Werror -pedantic -Wshadow -Wconversion -fvisibility=hidden -std=c99) + set(PROJECT_WARNING_FLAGS -Wall -Wextra -Werror -pedantic -std=c99)
57-65: STOP MAKING -nostdlib OPTIONAL. This is the EXACT same bug from the last review.You gutted the policy AGAIN by wrapping -nostdlib in a CMake option that defaults to OFF. The past reviewer EXPLICITLY told you to:
- Delete GITLEDGER_USE_NOSTDLIB entirely
- Apply -nostdlib unconditionally to every executable (with MSVC guard only)
Putting -nostdlib on the static library (line 64) is pointless—archives never link anything. The function you wrote (lines 57–61) makes executables a luxury feature. That's BACKWARDS. Here's what you're doing wrong:
add_nostdlib()checksGITLEDGER_USE_NOSTDLIB AND NOT MSVC- Option defaults to OFF
- Executables don't get -nostdlib by default
- Policy is toast
REMOVE the option. DELETE the function (or turn it into a no-op). Apply -nostdlib directly to each executable target with only an MSVC guard:
- function(add_nostdlib target) - if(GITLEDGER_USE_NOSTDLIB AND NOT MSVC) - target_link_options(${target} PRIVATE -nostdlib) - endif() - endfunction() - if(NOT MSVC) - # Keep library pure/freestanding from the linker perspective. - target_link_options(gitledger PRIVATE -nostdlib) - endif()Then apply this to each executable (see next comment).

Remove GITLEDGER_USE_NOSTDLIB option; it's dead code now.
Line 29 defines an option that makes -nostdlib optional. Delete it. The policy says it's mandatory (guarded only for MSVC). An opt-in option contradicts that. As per coding guidelines and the previous review feedback.

Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

In CMakeLists.txt around line 29, remove the dead option definition
'option(GITLEDGER_USE_NOSTDLIB "Link executables with -nostdlib (non-MSVC)"
OFF)'; delete that line and any references that conditionally use
GITLEDGER_USE_NOSTDLIB so the build always follows the mandatory -nostdlib
policy (keep MSVC guard intact), ensuring no remaining logic depends on the
removed option.

111-120: Your error check is mathematically impossible.Line 114: You're checking if
gitledger_semantic_version_snprintfreturns0U. Except your shiny new implementation ALWAYS returns the required length, which for even "0.0.0" is 5. The check on line 114 will NEVER be true. This is either dead code left over from the old implementation, or you don't understand your own code.If you want to detect errors, you need a different sentinel value (like SIZE_MAX) or actually check the write_decimal return values in the previous function so errors can propagate.
Either remove the dead check:
const char* gitledger_semantic_version_string(void) { - if (gitledger_semantic_version_snprintf(gitledger_version_buffer, - sizeof(gitledger_version_buffer)) == 0U) - { - return NULL; - } - + (void) gitledger_semantic_version_snprintf(gitledger_version_buffer, + sizeof(gitledger_version_buffer)); return gitledger_version_buffer; }Or fix your error propagation (see previous comment).

GITLEDGER_USE_NOSTDLIB) and Meson (exec_nostdlib) support, and a newfreestanding-linuxGitHub Actions job. Deliverables, implementation notes, tests/verification, and definition of done are all well-defined.Re: static analysis errors (MD024, MD003): The duplicate-heading warnings (e.g., lines 249, 253, 259, etc.) are artifacts of the templated structure—every milestone issue repeats
## Summary,## Links / Context, etc. The MD003 error at line 244 is a false positive (that line is YAML frontmatter, not a Markdown heading). Since this file is auto-generated fromdocs/ISSUE-BREAKDOWN.md, lint config should already accommodate this pattern; if not, those issues belong in the source document.

Lines 57 and 59: You're casting GL_VERSION_DECIMAL_BASE to (uint32_t) when comparing and dividing with value, which is already uint32_t. The integer constant will be implicitly promoted. These casts are pure noise that suggest you don't understand C's integer promotion rules.
Apply this diff to remove the clutter:
static size_t decimal_length(uint32_t value)
{
size_t len = 1U;
- while (value >= (uint32_t) GL_VERSION_DECIMAL_BASE)
+ while (value >= GL_VERSION_DECIMAL_BASE)
{
- value /= (uint32_t) GL_VERSION_DECIMAL_BASE;
+ value /= GL_VERSION_DECIMAL_BASE;
++len;
}
return len;

In src/version.c around lines 54 to 63, remove the unnecessary casts of
GL_VERSION_DECIMAL_BASE to (uint32_t) in the while condition and the division;
simply compare and divide value by GL_VERSION_DECIMAL_BASE directly (value >=
GL_VERSION_DECIMAL_BASE and value /= GL_VERSION_DECIMAL_BASE) since value is
already uint32_t and the constant will be promoted, leaving the rest of the
function unchanged.

Ignoring errors and violating your own guidelines? Really?
Lines 89, 92, 95: You're explicitly casting write_decimal return values to (void). So if write_decimal fails—which it CAN if the internal invariants break—you'll merrily copy garbage from your scratch buffer, return a confidently-wrong "required" length, and the caller will have no idea they got trash. Sure, your buffer should be big enough and version components should fit in 10 digits, but you wrote error-checking code in write_decimal for a reason. Ignoring it here is lazy and dangerous.
Lines 75, 84, 98: Your comments blatantly violate your own coding guidelines: "Comments must explain WHY, not WHAT." Let's review your failures:
- Line 75: "No write; return the number of chars that would have been written." — That's WHAT. WHY do we have this case? Because snprintf semantics demand it.
- Line 84: "Render into a scratch buffer guaranteed to be large enough, then copy." — That's WHAT. WHY this approach? To avoid partial writes and simplify truncation logic.
- Line 98: "Copy up to n-1 bytes and NUL-terminate." — Congrats, you've described the next 10 lines of code. WHY are we doing manual copy instead of memcpy? Because... reasons?
Either follow your guidelines or delete them.
Check the write_decimal return values properly:
- (void) write_decimal(GITLEDGER_VERSION_VALUE.major, &cursor, &remaining);
+ if (!write_decimal(GITLEDGER_VERSION_VALUE.major, &cursor, &remaining))
+ {
+ buf[0] = '\0';
+ return 0; /* indicate error */
+ }
*cursor++ = '.';
--remaining;
- (void) write_decimal(GITLEDGER_VERSION_VALUE.minor, &cursor, &remaining);
+ if (!write_decimal(GITLEDGER_VERSION_VALUE.minor, &cursor, &remaining))
+ {
+ buf[0] = '\0';
+ return 0;
+ }
*cursor++ = '.';
--remaining;
- (void) write_decimal(GITLEDGER_VERSION_VALUE.patch, &cursor, &remaining);
+ if (!write_decimal(GITLEDGER_VERSION_VALUE.patch, &cursor, &remaining))
+ {
+ buf[0] = '\0';
+ return 0;
+ }And fix your comments to explain WHY, not WHAT:
if (n == 0U)
{
- /* No write; return the number of chars that would have been written. */
+ /* snprintf semantics: when n is 0, only return required length. */
return required;
}
if (buf == NULL)
{
- return required; /* mirror snprintf: behave as if only returning length */
+ return required; /* snprintf allows NULL buf for length queries. */
}
- /* Render into a scratch buffer guaranteed to be large enough, then copy. */
+ /* Two-phase render avoids partial writes and simplifies truncation. */
char tmp[GL_VERSION_BUFFER_SIZE];
...
- /* Copy up to n-1 bytes and NUL-terminate. */
+ /* Truncate to fit user buffer, preserving NUL-termination. */BunBun
