Release Notes

Drop-in replacement for v1.2.1. No file-format changes, no public API changes.

Bug fixes

  • Two handles on one file in the same process (#304): FileLock::acquire treated a lock file whose holder PID equalled our own as stale, deleted it, and opened anyway — on the theory that it could only be a leaked handle. The far more likely cause is a handle that is open and in use right now elsewhere in the process, so the "self-heal" silently produced two live FileBackends on one file. Each caches its own header.page_count, allocates new pages from that count, and bounds-checks read_page against it, so the two page tables diverge. That — not an allocation off-by-one — is the source of the intermittent Page N out of bounds (total pages: M). It also corrupted the lock itself: whichever handle dropped first ran FileLock::drop and removed the lock file that by then belonged to the survivor, leaving a live handle unlocked and admitting other processes too. A lock held by our own PID is now refused with an error naming the same-process case; a lock held by a different, dead process is still reclaimed as before. Behaviour change: callers that relied on reopening a path they already hold open now get an error instead of silent corruption, and should reuse the existing handle (Minigraf is cheap to clone and all clones share one database).

  • String comparison in predicates: [(< ?a ?b)], >, <= and >= now order two strings lexicographically instead of failing. Previously every ordering predicate routed through to_float_pair, which errors on non-numeric operands, so a string comparison silently matched no rows — and because both directions returned nothing, a range filter dropped the entire relation rather than partitioning it. This most often bit ISO-8601 timestamps stored as strings. The predicate path now agrees with value_lt / value_cmp, which min, max and :order-by already use. Mixed-type comparison (string vs number) remains an error, and NaN comparisons remain false.
