40 check-ins using file src/tclsqlite.c version 649d373f

2014-02-13
21:57
Improvements to the makefile and README for MSVC. (check-in: b22b6140 user: mistachkin tags: trunk)
19:27
Ensure that if the "psow=0" URI option or FCNTL_POWERSAFE_OVERWRITE file-control is used to clear the power-safe overwrite flag, extra padding frames are added to the WAL file. (check-in: 48c821fd user: dan tags: trunk)
19:10
Change README to README.md and expand it. Remove unrelated and obsolete files. (check-in: 18d4e258 user: drh tags: trunk)
18:46
Avoid passing a flags argument with the internal WAL_SYNC_TRANSACTIONS bit set when calling sqlite3OsSync(). (check-in: e3b79e92 user: dan tags: trunk)
13:42
Update the tclconfig files to the latest from http://core.tcl.tk/tclconfig. (check-in: b81ba7a4 user: drh tags: trunk)
2014-02-12
23:52
Minor simplifications to the "zeroPage()" routine in btree.c. (check-in: cc8f10bc user: drh tags: trunk)
21:31
Remove the "rowid cache" that sought to remember the largest rowid for a table and thereby speed up OP_NewRowid. That cache was ineffective. Removing it results in a performance increase of 0.4%, less memory usage, and a slightly smaller library size. (check-in: 56bc5ce8 user: drh tags: trunk)
15:05
Various fixes and test case updates so that veryquick.test passes again. (Leaf check-in: f352ef57 user: dan tags: deferred-open)
14:43
Make sure "rowid" columns are correctly resolved in joins between normal tables and WITHOUT ROWID tables. Fix for ticket [c34d0557f740c45070]. (check-in: 5d01426d user: drh tags: trunk)
14:43
Merge latest trunk changes. (check-in: 4d7057c4 user: dan tags: deferred-open)
2014-02-11
19:35
Test case updates to account for the fact that database files are not created until they are first written. (check-in: 8ef97420 user: dan tags: deferred-open)
16:24
Increase the version number to 3.8.4 (check-in: 0a8bcbbd user: drh tags: trunk)
16:22
Updates to the command-line shell. Simplify the banner message. Add the ".save" command as an alias for ".backup". When starting with no arguments, include a banner message warning that the database is transient and in-memory and mention the ".open" command. (check-in: f5ad1e1b user: drh tags: trunk)
14:37
Fixes to the "editline" support in the command-line shell. (check-in: 7989ce5f user: drh tags: trunk)
05:26
Merge latest trunk changes. (check-in: 1f2e1b0c user: dan tags: deferred-open)
01:50
Make sure that virtual WHERE-clause terms do not get transformed into real terms when processing set of OR-connected terms. Fix for ticket [4c86b126f22ad]. (check-in: c950d6c4 user: drh tags: trunk)
2014-02-10
21:09
Fix a bug causing the POWERSAFE_OVERWRITE device-characteristic flag to be set incorrectly if file opening is deferred. (check-in: 95d0c58d user: dan tags: deferred-open)
21:07
Fix a pointless conditional. Add a test case. (check-in: 9367632d user: drh tags: trunk)
19:59
Add the ".save" command as an alias for ".backup". Improvements to the way font changes are implemented on the in-memory database warning. (Closed-Leaf check-in: fe284afe user: drh tags: memdb-warning)
19:37
Experimental change to os_unix.c to delay creating a database file until it is first written. (check-in: 538f7b25 user: dan tags: deferred-open)
19:36
On unix, make the "transient in-memory database" text bold, but not red. Leave the text read on windows. (check-in: c9eba2f7 user: drh tags: memdb-warning)
19:27
In the command-line shell, on the banner, warn about the use of a transient in-memory database in bold red text. (check-in: 0fbc0fce user: drh tags: memdb-warning)
18:56
Fix the compound-select-to-subquery converter so that it works with the new compound-select object linkage introduced as part of the fix for ticket [31a19d11b97088296]. (check-in: 572d4be4 user: drh tags: trunk)
16:13
Modify the command-line shell to print a warning when using an in-memory database. (check-in: 90e9deae user: drh tags: memdb-warning)
15:56
Improvements to a "Synopsis:" comment in the VDBE engine. (check-in: 0dfa7ee9 user: drh tags: trunk)
12:59
Faster implementation for sqlite3MulInt64(). (check-in: 010c48f6 user: drh tags: trunk)
03:21
Faster and smaller implementation of sqlite3_value_type(). (check-in: 5708bc24 user: drh tags: trunk)
2014-02-09
23:59
Add a compound-query test to the speedtest1 test program. (check-in: 53299575 user: drh tags: trunk)
18:02
Use the WITH clause to help resolve names for SELECT statements on the left of a compound query. Proposed fix for ticket [31a19d11b97088296a]. (check-in: 67bfd59d user: drh tags: trunk)
00:52
Add the Mandelbrot Set testcase to the "cte" testset of speedtest1. (check-in: 56febbeb user: drh tags: trunk)
00:18
Add a new "testset" to the speedtest1 program: The sudoku solver. (check-in: 4677ef2f user: drh tags: trunk)
2014-02-08
23:20
Do away with the "multi-register pseudo-table" abstration. Instead, just use an OP_SCopy to load results directory from the result registers of the co-routine. (check-in: 1e64dd78 user: drh tags: trunk)
19:12
Change the OP_Found opcode so that it expands zero-blobs prior to comparing them. Fix for ticket [fccbde530a6583b] (check-in: e2303d1b user: drh tags: trunk)
13:24
Fix a harmless compiler warning in VS2013. (check-in: 83116ee3 user: drh tags: trunk)
13:12
Tweaks to the generated VDBE code to make it a little easier to follow. (check-in: 129217ee user: drh tags: trunk)
04:24
Enable constant expression factoring even if no tables are read and no transaction is started. (check-in: a45b8771 user: drh tags: trunk)
01:40
Change the OP_Trace opcode to OP_Init and give it the ability to jump to the initialization code at the bottom of the program, thus avoiding the need for an extra OP_Goto. (check-in: 192dea97 user: drh tags: trunk)
2014-02-07
22:21
Add opcodes OP_InitCoroutine and OP_EndCoroutine. Use these to remove the need for separate boolean registers to record when a co-routine has finished. (check-in: 5a88b6a7 user: drh tags: trunk)
19:33
Fix redundant definitions of _LARGE_FILE and _LARGEFILE_SOURCE. (check-in: 4043d879 user: drh tags: trunk)
19:26
In the TCL bindings, make sure Tcl_AppendResult() is always terminated by "(char*)0" and not just "0". (check-in: ea4d23d1 user: drh tags: trunk)
