Bit 0.15.0

Features

  • feat(pkg/mysql): rewrite $N placeholders to ?, with the corpus that proves it never misfires (74fbf1c)
  • feat(pkg/mysql): COM_STMT_PREPARE/EXECUTE binding, typed errors and the statement cache (792be17)
  • feat(sql): find/findOne/findOneOrFail map a query result into a typed T (b08000f)

Fixes

  • fix(scripts): keep the build log the refusal path names (5883c83)
  • fix(pkg/mysql): count ? markers, not distinct parameters, against the server's prepare (0d3feb4)
  • fix(stress): re-sample load before wave 2 so the batch deadline can scale (4d1bdd3)
  • fix(stress): resample load per wave-2 job, not just once before the wave (ec04e3d)
  • fix: re-point stale spec/SPEC.md:3193 citations to :3243 (4b28718)

Compiler

  • slice 1: decimal as a predeclared scalar, with its §15.4 literal and §12.9 conversion rules (b419245)

  • upgrade.bit: cite osSelfExe and the observed brew keg path (c0e70fa)
  • fixmain: pre-push reds on e4cb1e3 — primIndexByName/lowerExprH back under their complexity baselines (aliases and tag dispatch split out), std/sql Pool.begin removal allowlisted for (595abf6)
  • parser: split the literal/access productions out of parserexpr.bit into parserlit.bit (bda025c)
  • fmt reaches its fixpoint in one pass for a comment-only arrow body (d2aa8aa)

  • teach bit fmt to print JSX elements and fragments (73ed8c2)
  • slice 1b: a decimal return and a decimal field set in a composite literal (e471174)

Build and tooling

  • repin stage0 to 0.14.0 (v0.14.0 at 76df603), four digests replaced, header records the move (09547c0)
  • selfhost-diffruntime: RELOC_DECLARED emptied, the 0.14.0 pin caught up with the seven inlined leaves (9ded6d7)
  • release-verify: the stage0 pin check derives the expected line count from the file (four triples since ), no hardcoded 3 (27d2d0b)
  • verify a pre- tag by falling back to the caller's abitwopass tooling (2792079)
  • install.sh/upgrade.sh: capture the releases/latest body instead of piping into grep -m1 (2f4fc51)
  • selfhost-diffdump.sh's ast/tokens/diags row stops conflating exit status with a tree divergence (2a3d252)
  • fix selfhost-diffdoc.sh's fabricated-mismatch risk from a merged stdout+stderr capture (d3879d7)
  • add test-taskwords-sizing, a gate that every schedTaskInit array-base site sizes via taskWords (d6670ae)

  • tools/gentzdata: generate stdlib/tz/data.bit from a zoneinfo directory (3bf7d4d)
  • tools/gentzdata: correct the documented run line — the file target is refused for a directory module, it must be 'bit run tools/gentzdata' (6e9a42e)
  • tools/build: register test-no-emdash, a Gate{}+Step{} zero-em-dash check (df9efc3)
  • hostTriple() treats an empty read as "could not determine the host" (42ac982)
