| 19:03 | For the MSVC makefile, recompile vdbe.lo and parse.lo first. check-in: 9e819f0f user: mistachkin tags: trunk | |
| 15:54 | Comment and preprocessor macro cleanup. check-in: c0809b5e user: drh tags: trunk | |
| 13:51 | In main.mk, always recompile vdbe.o and parse.o first, since changes to either parse.y or vdbe.c will cause all files to be recompiled and if there are syntax errors in vdbe.c or parse.y we want to hit them early in the compile process. check-in: a94a66d1 user: drh tags: trunk | |

| 17:07 | In the command-line shell, work around the fact that popen() and pclose() are not defined in stdio.h. in C89 and later. check-in: 8bcbb33f user: drh tags: trunk | |
| 16:41 | Fix a typo in main.c: SQLITE_DEAULT_AUTOMATIC_INDEX -> SQLITE_DEFAULT_AUTOMATIC_INDEX check-in: cc78e21c user: dan tags: trunk | |
| 16:27 | Enhance the progress handler so that it keeps track of the number of VDBE cycles across sqlite3_step() calls and issues callbacks when the cumulative instruction count reaches threshold. check-in: 4698a82e user: drh tags: trunk | |
|
2013-07-20

| 18:28 | Fix a typo in the previous commit. Closed-Leaf check-in: cd9096e6 user: dan tags: typo | |
| 17:12 | Ensure that all auxiliary data registered by calls to sqlite3_set_auxdata() is destroyed when the VM is halted. Partial fix for [406d3b2ef9]. DRH adds: Stray text accidentally inserted into vdbe.c just prior to the commit breaks the build. check-in: 71effa59 user: dan tags: typo | |
| 14:50 | Fix a 8-byte alignment problem in the query planner that might cause problems on sparc when compiled with -m32. check-in: 5dcffa67 user: drh tags: trunk | |
| 14:16 | Documentation changes to warn that sqlite3_set_auxdata() might call the destructor even before it returns. Also fix the regexp extension to deal with that case. Ticket [406d3b2ef91c]. check-in: 7acc8cd3 user: drh tags: trunk | |
|

| 11:54 | Clear the error string pointer in sqlite3_vtab object after the error string is transferred to SQLite. Ticket [78588b938a11]. check-in: 64bf8148 user: drh tags: trunk | |
|
2013-07-16
| ||
| 23:26 | Make sure the sqlite3_prepare16 and sqlite3_prepare16_v2 interfaces do not read past a zero-terminator if the nBytes parameter is too large. check-in: 20dba3a7 user: drh tags: trunk | |
| 21:31 | Enhance the query planner so that it looks at multiple solutions to OR expressions in the WHERE clause. check-in: 5e19d054 user: drh tags: trunk | |
|
2013-07-15

|
2013-07-12
| ||
| 21:09 | Make sure the shell does not try to put a zero terminator on the end of an unallocated zero-length string when running ".import" on an empty file. check-in: 92adaee5 user: drh tags: trunk | |
|

| 19:04 | Change the description of how sqlite3_progress_handler() works so that the N parameter is "approximate". This aligns with the current implementation. This is a documentation change only. No changes to code. check-in: 7d829bde user: drh tags: trunk | |
| 15:22 | Add the experimental "query_only" pragma. check-in: 6557c407 user: drh tags: trunk | |
| 15:03 | Add the "defer_foreign_keys" pragma and the SQLITE_DBSTATUS_DEFERRED_FKS value for sqlite3_db_status(). This is a cherry-pick of a sequence of five checkins in the sessions branch between [1d44e5d3c2] and [d39e65fe70]. check-in: 527121ac user: drh tags: trunk | |

| 18:14 | Fix harmless compiler warnings in the progress callback logic. check-in: 908141d5 user: drh tags: trunk | |
| 13:33 | Experimental "PRAGMA query_only=BOOLEAN" statement that is able to turn write capabilities on and off. Closed-Leaf check-in: ece960c4 user: drh tags: query_only | |
| 03:05 | Run progress callback checks less frequently in the main VDBE evaluation loop. This makes up for the extra CPU cycles used to increment the cycle counter for SQLITE_STMTSTATUS_VM_STEP. check-in: 3e8b0201 user: drh tags: trunk | |
|

| 21:12 | Fix an adverse interaction between the IS NOT NULL optimization (available only with SQLITE_ENABLE_STAT3) and the transitive constraint processing. Fix for ticket [d805526eae253] check-in: 3b30b75b user: drh tags: trunk | |
| 01:27 | Add an optional 5th parameter to the next_char() function that is the collating sequence to use for comparison. check-in: 9415db6e user: drh tags: trunk | |

| ||
| 18:07 | Fixes for test cases running in the "mmap" permutation. check-in: cdb97d41 user: dan tags: trunk | |
| 17:57 | Drop any existing mapping of the database file when exiting the pager "error state", as it may at this point be too large for the database file. Do not invoke file-control MMAP_SIZE if the database file handle does not support xFetch and xUnfetch (on the grounds that xUnfetch(0) calls to invalidate the mapping cannot be made). check-in: 0ae7e75b user: dan tags: trunk | |

|
2013-06-29
| ||
| 15:40 | Fix the build of the command-line shell on windows. Windows uses "_pclose" rather than "pclose" as the pointer to the function that closes a popen pipe. check-in: b003b2b2 user: drh tags: trunk | |
|
2013-06-28
| ||
| 23:55 | Issue the new SQLITE_WARNING_AUTOINDEX warning on the SQLite log whenever an automatic index is created. check-in: 338826ef user: drh tags: trunk | |
| 21:12 | Add the SQLITE_DEFAULT_AUTOMATIC_INDEX compile-time option, which if set to zero turns automatic indices off by default. Increase the estimated cost of an automatic index. Additional minor refactoring of the automatic index code. check-in: 459b3179 user: drh tags: trunk | |
| 19:41 | Allow read transactions to be freely opened and closed by SQL statements run from within the implementation of user-functions if the user-function is called by a SELECT statement that does not access any database tables (e.g. "SELECT user_function();"). check-in: f308c485 user: dan tags: trunk | |
| 17:29 | Add a bit to the SQLITE_TESTCTRL_OPTIMIZATIONS option for sqlite3_file_control() that will disable the use of SQLITE_STAT3 information in the query planner. check-in: 60c19b86 user: drh tags: trunk | |

|
2013-06-27
| ||
| 23:54 | Refactor names of fields in the sqlite3 object: "activeVdbeCnt" becomes "nVdbeActive". Related fields becomes "nVdbeRead", "nVdbeWrite", and "nVdbeExec". check-in: 14f79696 user: drh tags: trunk | |
| 19:12 | Fix an error in e_expr.test. check-in: fd4ece18 user: dan tags: trunk | |
| 17:40 | Make sure that sqlite3_stmt_readonly reports false for PRAGMA journal_mode and PRAGMA wal_checkpoint. Ticket [a589ec069e3]. Also keep track of whether a prepared statement does no reading or writing. check-in: 1937fd8e user: drh tags: trunk | |
| 14:24 | Add a test to ensure that if BEGIN IMMEDIATE fails with SQLITE_BUSY, it does not leave the user with an open read transaction (unless one was already open). check-in: 22bced36 user: dan tags: trunk | |
| 14:07 | If the filename argument to the ".import" command in the command-line shell begins with '|' then treat it as an input pipe rather than a file. check-in: 4c02b344 user: drh tags: trunk | |
| 13:26 | Improved handling of backslash escapes on double-quoted arguments to dot-commands in the command-line shell. check-in: 656a1fe5 user: drh tags: trunk | |
| 13:01 | The undocumented and unsupported ".selftest" command in the command-line shell utility is now only available if compiled with SQLITE_DEBUG. Also fix a windows compiler warning in that command. check-in: e88fd5b2 user: drh tags: trunk | |
| 11:46 | Add extended error code SQLITE_BUSY_SNAPSHOT - returned in WAL mode when a read-transaction cannot be upgraded to a write-transaction because it is reading from a snapshot other than the most recently committed. check-in: 361c2296 user: dan tags: trunk | |
