13 check-ins using file src/vdbe.c version 49e659bc
|14:46||Use exponential buffer size growth in StrAccum, as long as the size does not grow to large, to avoid excess memory allocation resize operations. Also, document the fact that setting scratch memory causes SQLite to try to avoid large memory allocations. check-in: a518bc33 user: drh tags: trunk|
|13:24||When enlarging the size of a StrAccum object, use sqlite3DbMallocSize() to record the entire size of the allocation, not just the requested size. check-in: 3dda3c93 user: drh tags: trunk|
|18:32||Add requirements marks and make minor tweaks to documentation. check-in: 49188b2b user: drh tags: trunk|
|14:46||Change the command-line shell man-page to use the ".tr" troff directive instead of ".cc" for escaping the initial "." characters in the ".help" output. check-in: 67f0d469 user: drh tags: trunk|
|14:26||Simplify the logic in the cell redistribution loop of balance_nonroot(). Enhance and clarify comments and add assert() statements for additional verification of correctness. check-in: a07078b6 user: drh tags: trunk|
|12:22||Simplify the math slightly, and reduce by one the number of loop iterations, for the loop in balance_nonroot() that moves cells between pages. check-in: 2e838db8 user: drh tags: trunk|
|10:31||Add the "varint.c" utility program in the tool directory. check-in: ea5d56be user: drh tags: trunk|
|02:51||Remove an unnecessary branch from balance_nonroot(). check-in: 9fc7c88e user: drh tags: trunk|
|00:05||In the balance_nonroot() routine, protect the values in aPgno array from change during the page sort, so that aPgno can be used to avoid unnecessary pointer-map updates for auto_vacuum databases. check-in: 69c3924f user: drh tags: trunk|
|23:14||Improvements to the wording of some comments. Reinstate an assert() that is only true for non-corrupt database files by adding an "|| CORRUPT_DB" term. check-in: 67adb448 user: drh tags: trunk|
|20:48||Tweaks to comments in btree.c. Minor code changes to enhance testability. check-in: c7d9aa3a user: drh tags: trunk|
|18:20||Fix the %c format character in sqlite3VXPrintf() so that it correctly handles precisions larger than 70. check-in: 08a27440 user: drh tags: trunk|
|00:58||In the OP_Column opcode, when extracting a field that is past the end of a short record (because the row was originally inserted prior to ALTER TABLE ADD COLUMN) then make sure the output register is fully NULL and does not contain leftover flags (such as MEM_Ephem) from its previous use. Fix for ticket [43107840f1c02]. check-in: 24780f8d user: drh tags: trunk|
