5df13a0e80 Merge pull request #1387 from mattn/codex/stmt-cache 
[codex] add opt-in statement cache
 2026-04-08 22:29:35 +09:00
Yasuhiro Matsumoto
e302e5cb8c document that _stmt_cache_size is per connection 
Clarify that each connection in the sql.DB pool maintains its own
independent statement cache.

867dcbfbdc move reset/clear into putCachedStmt and always finalize on failure 
This avoids an unnecessary reset when the cache is full, guarantees
a statement cannot enter the cache without being reset/cleared, and
fixes a leak where sqlite3_finalize was not called when reset failed.

0e58fa4d72 simplify prepareWithCache to call prepare instead of duplicating logic 
prepareWithCache now delegates to prepare and sets cacheKey
afterward, removing the useCache boolean parameter.

e9f47da5c5 do not bail out on finalize error in closeCachedStmtsLocked 
Finalize all cached statements even if one fails. Leaving a
finalized statement in the cache map would be a use-after-finalize
bug per SQLite documentation.

325cb8d5d9 remove redundant stmtCacheSize check in putCachedStmt 
When stmtCacheSize <= 0, stmtCacheCount >= stmtCacheSize is always
true, so the explicit check is unnecessary.

061c2a5f43 check stmtCacheSize before acquiring mutex in takeCachedStmt 
stmtCacheSize is immutable after connection open, so checking it
before the lock avoids mutex overhead when cache is not enabled.

reduce CGO call overhead for exec and bind paths
 2026-04-06 22:36:14 +09:00
Yasuhiro Matsumoto
89f4bbe489 fix build with SQLITE_ENABLE_UNLOCK_NOTIFY 
Move extern declarations for _sqlite3_*_blocking functions before
_sqlite3_exec_no_args which references them. Remove unused
_sqlite3_prepare_v2_nolen function.

49540487ae reduce CGO call overhead for exec and bind paths 
- Add _sqlite3_exec_no_args() C function that combines prepare+step+finalize
  into a single CGO crossing for parameterless exec (most common case)
- Add _sqlite3_reset_clear() C function that combines sqlite3_reset and
  sqlite3_clear_bindings into a single CGO crossing
- Use semaphore channel instead of result struct channel in context-aware
  exec/Next paths to reduce allocations
- Use time.AppendFormat with stack buffer to avoid heap allocation in
  time.Time binding
- Optimize bindNamedIndices to reuse a single buffer instead of 3
  separate C.CString allocations
- Remove intermediate bindIndices slice allocation in named parameter
  binding path
- Pass explicit query length to sqlite3_prepare_v2 to avoid C-side strlen

Eliminate unnecessary bounds checks in hot paths

8f9f86ea43 Eliminate unnecessary bounds checks in hot paths 
- Replace len(args[start:start+na]) > 0 with na > 0 to avoid slice bounds check
- Use range loops instead of manual index loops for cols/decltype slices
- Use range variable v.Ordinal instead of re-indexing args[i].Ordinal
- Add bounds hint for decltype access in nextSyncLocked loop
