v0.1.2

fca0664d · Bump version to 0.1.2 · Apr 30, 2026

v0.1.2 — Fix buffer leak and null pointer dereference

Fixed:
- Buffer leak in Diff#patch and Patch#to_s when an exception was raised
  after git_patch_to_buf but before git_buf_dispose
- Segfault in Error.last when no libgit2 error was pending (null pointer
  dereference)

Added:
- Error.check! — raises the last error if one is pending (replaces Error.raise?)
- Error.clear — wraps git_error_clear() to reset pending error state

Changed:
- TagCollection#exist? is now O(1) via git_reference_lookup instead of
  iterating all tags

Deprecated:
- Error.raise? — use Error.check! instead (emits compile-time warning)

Release: Agate v0.1.1

v0.1.1 — Fix heap corruption on libgit2 1.7.x

Fixed:
- Heap corruption on Ubuntu 24.04 / glibc 2.39 / libgit2 1.7.2 caused
  by GC finalizers double-freeing recycled malloc addresses (closes #2)
- Memory leak in Commit.alloc_c_sigs on second allocation failure
- to_strarray lifetime hazard (now block-scoped with_strarray)
- InitOptions string lifetime (retained as instance variables)
- Exception safety in Repository#each_id and Tree#walk C callbacks
- Missing #hash on Commit, Object, Reference, Repository

40/40 consecutive passes on Ubuntu 24.04 with libgit2 1.7.2
(previously crashed ~60-80% of runs).
