54 check-ins using file src/btree.c version ca9f4486

2011-03-17
19:20
Change to the session module to use user-defined primary keys instead of rowids when collecting changes. (check-in: 6614cfcb user: dan tags: sessions)
2011-03-16
19:59
Add the sqlite3_preupdate_new() API, for retrieving the new.* values from within a pre-update callback. (check-in: 526545c4 user: dan tags: sessions)
09:49
Remove the sqlite3_transaction_hook() API. (check-in: b0015a1c user: dan tags: sessions)
2011-03-15
16:37
Fix some bugs and other code issues in the session module. (check-in: f2930840 user: dan tags: sessions)
2011-03-14
19:49
Fix handling of return values from the conflict handler. Document the conflict handler arguments and return codes in sqlite3session.h. (check-in: cbbb274e user: dan tags: sessions)
2011-03-12
17:22
Fix some issues with UPDATE changes in the session module. (check-in: 57862efe user: dan tags: sessions)
2011-03-11
19:05
Add the sqlite3changeset_apply() function. Does not yet handle all cases. (check-in: 2b19be7b user: dan tags: sessions)
2011-03-09
11:17
Add a function to the session extension invert a changeset. (check-in: 75d5dff7 user: dan tags: sessions)

Add start of sessions feature. (check-in: 269a81a3 user: dan tags: sessions)
2011-03-05
21:41
Simplifications to the overflow-free multiplier. Also remove some commented-out code that was left in that subroutine by mistake on the previous check-in. (check-in: 55fc25fd user: drh tags: trunk)
20:59
Fix all known instances of signed-integer overflow. Within SQL expressions, integer overflow now forces coercion to floating point. The shift operators work with any integer right-hand operand with negative values reversing the direction of the shift. (check-in: abf21394 user: drh tags: trunk)
13:54
Fix an instance of signed arithmetic overflow and an one bit-shift overflow. Mark six other signed arithmetic overflow locations that need fixing. (check-in: 04abab71 user: drh tags: trunk)

15:09
Proof-of-concept prototype for the proposed xSetSystemCall extension method on the VFS. (check-in: 92b5a76a user: drh tags: syscall-override)
02:08
Log all error from close() in os_unix.c to sqlite3_log() but do not attempt to report errors back up to the application. Update the unix error logging to put the most important information earlier in the message. (check-in: 7b6e30e6 user: drh tags: trunk)
2011-03-01
18:42
Add the experimental sqlite3_preupdate_hook() API. (check-in: 6145d7b8 user: dan tags: sessions)
2011-02-25

2011-02-24
21:10
Fix a typo in a comment. No changes to code. (check-in: af475618 user: drh tags: trunk)
2011-02-23
22:39
Reserve a range of bits in the SQLITE_OPEN_xxxx bit vector for future expansion. (check-in: 9b904654 user: drh tags: trunk)
14:00
Fix a typo in the robust_flock() macro for systems without EINTR. (check-in: af9ba2a6 user: drh tags: trunk)
13:53
The robust_flock() fix that accidently included some unrelated, though harmless changes. I should follow my own checklist! (Closed-Leaf check-in: e701efbd user: drh tags: mistake)
13:33
Retry selected system calls on unix when they fail with EINTR. (check-in: b9d29ea3 user: drh tags: trunk)
2011-02-22
03:34
When a stale schema-cookie is seen, expire only the one statement that encountered the bad cookie, not every statement on the database connection. Ticket [b72787b1a7cea1f] (check-in: 1bca0a7e user: drh tags: trunk)
2011-02-21
17:49
Fix a problem with "EXPLAIN QUERY PLAN SELECT count(*) FROM tbl". (check-in: 9f9f3288 user: dan tags: trunk)
11:46
Have os_unix.c call sqlite3_log() following errors in certain system calls. (check-in: 01076528 user: dan tags: trunk)
2011-02-19
23:18
An SQLITE_PROTOCOL error counts as a locking error for verification purposes. (check-in: e87d499a user: drh tags: trunk)
17:02
Change a testcase() added by the previous checkin into an assert(). (check-in: 6f3dad32 user: drh tags: trunk)
16:51
Add testcase macros to verify that all return values from walTryBeginRead() are tested. (check-in: 262b6fca user: drh tags: trunk)
15:22
Changes to make WAL more robust against SQLITE_PROTOCOL errors. (check-in: fd578a32 user: drh tags: trunk)
2011-02-18
17:23
Fix the sqlite3ValueFromExpr() routine so that it returns SQLITE_NOMEM on an OOM when trying to extract a NULL. (check-in: 1061e94f user: drh tags: trunk)
2011-02-17
15:58
Remove a no-op code path from sqlite3ExprIsInteger(). Replace it with an assert() that proves it always does nothing. (check-in: 7af66d1b user: drh tags: trunk)
13:52
Remove an assert() that was made redundant by the previous checkin. (check-in: 21db7191 user: drh tags: trunk)

2011-02-11
22:54
Add a NEVER() around a test that is believed to always be false. (check-in: f7e2ea33 user: drh tags: trunk)
20:52
Skip flattening if subquery has LIMIT and outer query is DISTINCT. Fix for ticket [752e1646fc]. (check-in: 55973999 user: shaneh tags: trunk)
06:59
Fix a bug in the new WHERE-clause processing that tries to use an index to resolve IS NOT NULL constraints when SQLITE_ENABLE_STAT2 is defined. The bug could cause memory overruns and segfaults. The bug was new to the code and has not appeared in an official release. Found during structural testing. (check-in: a5c36b9f user: drh tags: trunk)

17:46
Prevent a segfault when automatic indices try to use a column with an unknown collating function. Ticket [77aa3b1e6592582e38605d36]. This check-in also removes some stray \r characters unrelated to the problem. (check-in: f01030a0 user: drh tags: trunk)
00:08
Refactor the cost function in the query planner. Give extra cost (thus reduce likelihood of selection) to full table scans. (check-in: 878da276 user: drh tags: trunk)
2011-02-09
19:55
Make sure code *compiles* with each OMIT and ENABLE option. Mostly changes to test modules. (check-in: 7cc515ed user: shaneh tags: trunk)
18:19
Do not report corruption if the the db size header field is greater than the file size on disk unless the two change-counter header fields are identical. Fix for ticket [89b8c9ac54]. (check-in: 00c4596f user: dan tags: trunk)
