When resetting any non-TEMP schema, also reset the TEMP schema since it might be holding references to the non-TEMP schema that just got reset. check-in: 211d5dde user: drh tags: schema-parse-refactor
16:28
Begin a series of changes designed to reduce the scope and frequency of invalidating schemas. Design goals are that the internal schema should never be deleted out from under a prepared statement that is running and that all prepared statements should be expired if the schema is invalidated. At the same time, minimize the number of schema invalidations. This change merely revises the sqlite3ResetInternalSchema() function to use -1 as the wildcard for "all" rather than 0, so that we can reset the main schema independently of all the others. check-in: 6a8ad6e3 user: drh tags: schema-parse-refactor
09:44
Fix a race condition in OP_ParseSchema. check-in: 71a799b0 user: dan tags: trunk

2011-04-01
23:49

Change analyze7.test so that it works without SQLITE_ENABLE_STAT2 defined. check-in: 9415201c user: dan tags: trunk
16:50
When simulating an error in the close() system call, close the file descriptor anyway. Otherwise long running tests leak too many file-descriptors and crash. check-in: 81ddbf43 user: dan tags: trunk
15:15

2011-03-23
22:54
Fix a signed/unsigned comparison compiler warning. check-in: c81da6f9 user: drh tags: trunk

01:58
Comment enhancement to better explain the logic in the "x IS NULL" optimization. check-in: 869f8947 user: drh tags: trunk

2011-03-12
18:10
In the "unix-excl" VFS, use the heap for shared memory, since only a single process is able to read or write the database. Closed-Leaf check-in: a05a6d40 user: drh tags: unix-excl
17:02
Add the new optional "unix-excl" VFS. This VFS grabs an exclusive lock on the database preventing other processes from accessing it, but continues to allow other database connections from the same process. check-in: 00051c32 user: drh tags: unix-excl
04:58

Unix errno integer can vary from one system to the next. So do not depend on specific errno values in test cases. check-in: ddb747d3 user: drh tags: trunk
13:06
Fix two compiler warnings. No functional code changes. check-in: c829868a 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
2011-03-04
15:43
Handle EINTR errors from open(). Closed-Leaf check-in: a7d176b2 user: drh tags: syscall-override

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
2011-02-25
03:25

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
