51 check-ins using file src/build.c version 8dbca259

2014-09-27
18:18
Fix a segfault in the sessions module that could follow an OOM. (check-in: 09985fa6 user: dan tags: sessions)
16:33
Fix a segfault in the streaming API functions triggered by a very long table name. (check-in: d2642543 user: dan tags: sessions)
12:26
Improve sessions module documentation and comments. Fix some other code issues. (check-in: bfc8bd80 user: dan tags: sessions)
2014-09-26
10:52
Fix a problem with concatenating patchsets containing DELETE and INSERT operations on the same row. (check-in: 4d8537ea user: dan tags: sessions)
2014-09-25
20:43
Add streaming version of sqlite3changeset_concat(). (check-in: 88eb6656 user: dan tags: sessions)
14:54
Add streaming version of sqlite3changeset_invert() to sessions module. (check-in: 8ded6a46 user: dan tags: sessions)
2014-09-24
17:13
Add streaming version of sqlite3changeset_apply(). Tests and fixes for the same and sqlite3changeset_start_str(). (check-in: b917fc14 user: dan tags: sessions)
04:38
Experiment using linear interpolation, instead of a strict binary search, when looking for integer-keyed rows on a single b-tree page. The experiment was not successful. The number of key comparisons is reduced by about 15%, but the added complexity of the search logic causes an overall reduction in performance. The patch is saved for historical reference only. (Closed-Leaf check-in: c705cf85 user: drh tags: linear-interpolation)
02:05
Have the clearCell() routine return the cell size to the caller, rather than have the caller make a separate call to cellSizePtr(). (check-in: f21d2175 user: drh tags: trunk)
01:23
Shorten all lines of source code in btree.c to at most 80 characters. No logical changes. (check-in: 5dd41cdb user: drh tags: trunk)
00:59
Add the MemPage.noPayload boolean and use it to help cellSizePtr() and btreeParseCellPtr() run faster. (check-in: 8e337531 user: drh tags: trunk)
2014-09-23
23:12
Remove an unused C-preprocessor macro. No functional changes to the code. (check-in: f480582c user: drh tags: trunk)
22:36
Avoid calling btreeParseCellPtr() from within fillInCell() since most of what btreeParseCellPtr() computes is ignored by fillInCell(). Instead, have fillInCell() compute the values it needs inline. Performance improvement. (check-in: 4147f667 user: drh tags: trunk)
21:25
Simplify the CellInfo structure for a size reduction and performance improvement. (check-in: bf59df66 user: drh tags: trunk)
20:39
Begin adding 'streaming' APIs to sessions module. This is a work in progress. (check-in: 3c7d3d95 user: dan tags: sessions)
18:30
Add the "multiplex_truncate" PRAGMA to the multiplexor extension, for querying and setting the truncate flag on a database connection. (check-in: d2962a5f user: drh tags: trunk)
01:40
Adjust skip-scan cost estimates slightly so that a full table scan is preferred over a skip-scan to a column with only two distinct values. (check-in: ae9a42b2 user: drh tags: trunk)
2014-09-22
20:38
Fix to payload size overflow detection in the cellSizePtr() change of the previous check-in. (check-in: 76097440 user: drh tags: trunk)
19:51
Size reduction and substantial performance increase for cellSizePtr(). (check-in: bc8bbf32 user: drh tags: trunk)
14:30
Tune the query planner to be more aggressive about using automatic indexes on views and subqueries for which there is not opportunity to declare a persistent schema index. (check-in: 41de1643 user: drh tags: trunk)
03:22
Disable shared memory operations using the unix-nolock VFS. (check-in: 10a6e510 user: drh tags: trunk)
2014-09-21
23:08
Merge in all recent changes from trunk. (check-in: 3967ebe8 user: drh tags: apple-osx)
22:49
Merge all recent trunk changes into the sessions branch. (check-in: 6406b77f user: drh tags: sessions)
22:31
Correctly handle an ORDER BY clause on an outer query when applying the compound-subquery flattening optimization. Ticket [d11a6e908f]. Also add the SQLITE_ENABLE_SELECTTRACE option for additional debugging and analysis information about select statement processing. (check-in: d5880abd user: drh tags: trunk)
20:31
Add test cases for ticket [d11a6e908f]. (Closed-Leaf check-in: 9683e001 user: drh tags: select-trace)
17:51
Add the "showauth" extension in ext/misc. (check-in: 28d52c1c user: drh tags: select-trace)
00:27
Improved ".selecttrace" output. (check-in: c0b61f70 user: drh tags: select-trace)
2014-09-20
20:38
Candidate fix for [d11a6e908f]. (check-in: 89398880 user: dan tags: select-trace)
20:24
Fix the SELECTTRACE_ENABLE macro so that it doesn't cause problems for testfixture. Add new SELECTTRACE() calls. (check-in: f1ba68f1 user: drh tags: select-trace)
18:18
Enable SELECT query planning tracing when compiled with SQLITE_ENABLE_SELECTTRACE and either SQLITE_DEBUG or SQLITE_TEST. (check-in: cbe0cf9d user: drh tags: select-trace)
00:35
Fix the usage of the _GNU_SOURCE and _BSD_SOURCE macros in the main internal header file, sqliteInt.h. Set HAVE_STRCHRNUL to 1 by default on Linux only. (check-in: 59e2c9df user: drh tags: trunk)
00:29
Only enable HAVE_STRCHRNUL by default on linux, as that is the only place it appears to work by default. (Closed-Leaf check-in: 0fac2c04 user: drh tags: sqliteIntMacros)
00:02
Revise macro usage in 'sqliteInt.h'. (check-in: 35db3e2f user: mistachkin tags: sqliteIntMacros)
2014-09-19
22:44
Simplify two conditionals and add testcase() macros to the affinity transform logic in the comparison operators. (check-in: 544664ca user: drh tags: trunk)
22:30
Recognize the invariant that a Mem object cannot be MEM_Dyn and have a non-zero szMalloc at the same time. Enforce this with assert()s and exploit it in the sqlite3VdbeMemClearAndResize() routine for a performance increase. (check-in: 3b21cf2b user: drh tags: trunk)
22:01
Tighten the conditions under which applyNumericAffinity() be called and add assert() statements to prove that it is never called otherwise. (check-in: e996ca32 user: drh tags: trunk)
20:13
Fix the affinity on inserts into the ANALYZE tables. Change the affinity characters to be upper case, to make the P5 parameter of comparison operators easier to read. (check-in: 3f3ca76a user: drh tags: trunk)
19:43
Do not attempt to extend the temp file if VFS version 3 is not supported and hence memory mapped I/O is unavailable. (check-in: 3ab20ba1 user: drh tags: trunk)
19:00
Make the "nolock" VFS on unix a version-3 VFS so that the sorter can use memory-mapped I/O. (check-in: 3db78d61 user: drh tags: trunk)
16:56
Remove a local variable from the OP_Column implementation, resulting in a modest size reduction and a performance increase. (check-in: 6199760d user: drh tags: trunk)
16:13
Small size reduction and performance increase for releaseMemArray(). (check-in: 24cd32d6 user: drh tags: trunk)
16:02
Updates to comments. No code changes. (check-in: 9b42c3da user: drh tags: trunk)
15:28
The OP_Column opcode runs faster and is smaller by manually in-lining the code that persists string values in the output register. (check-in: 36b613cc user: drh tags: trunk)
04:42
Add the sqlite3VdbeMemClearAndResize() function. Fix a sorting-index prefilter problem. (check-in: 987a7a21 user: drh tags: trunk)
02:01
Make sure that the sorting-index pre-filter recognizes that a rowid reference might be sortable. This fixes a performance regression. (Closed-Leaf check-in: 72727b68 user: drh tags: Cplusplus-comment)
00:43
Add the sqlite3VdbeMemClearAndResize() interface to be used in place of sqlite3VdbeMemGrow(). A C++ style comment was left in this check-in by mistake, and so it has been moved into a branch to avoid problems in any future bisects on windows. (check-in: 5b9b8987 user: drh tags: Cplusplus-comment)
2014-09-18
21:25
Add the Mem.szMalloc element to the Mem object and use it to keep track of the size of the Mem.zMalloc allocation. (check-in: 9c09ac35 user: drh tags: trunk)
18:55
Correct typos in comments. No changes to code. (check-in: 55879932 user: mistachkin tags: trunk)
17:52
Merge the Mem.r value into the MemValue union as Mem.u.r. Hence, a Mem can now store an integer or a real but not both at the same time. Strings are still stored in a separate element Mem.z, for now. (check-in: 4c8c89d7 user: drh tags: trunk)
16:28
Performance improvement for affinity transformations on comparison operators. (check-in: d7afdcba user: drh tags: trunk)
14:36
Since numeric affinity is the most common case, check it first. Interchange the NONE and TEXT affinity codes for easier checking of no affinity. (check-in: 4ef4c9a7 user: drh tags: trunk)
