17:41
Change the pager's sector size algorithm to the maximum of the size reported by xSectorSize() from the VFS and 512. It was using the maximum of xSectorSize() and the current page size, but that was adding an extra 512 bytes to the size of the journal file in the common case. (CVS 4929) check-in: 17ea0c97 user: drh tags: trunk
15:44
Changes to the Mem structure to reduce the frequency of freeing and reallocating the dynamic buffer. (CVS 4928) check-in: d0bf73d8 user: danielk1977 tags: trunk

07:42
If memory is leaked when running a test script with the --malloctrace option, write out a file called leaks.sql in the same format as mallocs.sql containing th e leaked applications.

2008-03-27
22:42

17:59
Allow creation of ephemeral pseudo-tables - pseudo-tables that copy a pointer to a row when inserted instead of copying the row data. (CVS 4924) check-in: 1a58a870 user: danielk1977 tags: trunk

12:46
Make sure an imbalance in the number of columns on a compound SELECT is detected and reported as an error before it can cause an assertion fault or array-bounds overflow in the code generator. Oops: part of the fix for ticket #3015 got included with this check-in by mistake. (CVS 4917) check-in: 50de87dc user: drh tags: trunk
2008-03-25
17:23
Modify the {quote: IdxDelete} opcode so that it takes an array of registers rather than a record formed using {quote: MakeRecord.} This avoids a needless packing and unpacking of the record to be deleted. (CVS 4916) check-in: ee381b43 user: drh tags: trunk
16:16
Test string values passed to bind_text() and result_text() for a nul-terminator. (CVS 4915) check-in: 24c3ebc0 user: danielk1977 tags: trunk
14:24
Have each {quote: BtShared} structure hang on to a buffer of just under page-size bytes for temporary use. This reduces the number of calls to malloc(). (CVS 4914) check-in: fe1bc0f3 user: danielk1977 tags: trunk
09:56
Fix for memory leak in malloc3.test. (CVS 4913) check-in: ef0e40e8 user: danielk1977 tags: trunk

Use a vdbe memory cell to allocate the space required for vdbe cursors. (CVS 4912) check-in: 04715364 user: danielk1977 tags: trunk
00:22
Removed the direct btree tests - part of the ongoing effort to test by calling only public interfaces. Modify the sqlite3VdbeRecordCompare interface to used a pre-parsed second key - resulting in a 13% performance improvement on speed1p.test. (CVS 4911) check-in: 0e1d84f2 user: drh tags: trunk
2008-03-24
12:51
Improved documentation of sqlite3_blob_open(). (CVS 4910) check-in: 1ed695f5 user: drh tags: trunk
2008-03-23
00:20

23:59
Bug fix in the newly revised sqllimit1.test script. (CVS 4908) check-in: 2a89fb3c user: drh tags: trunk
01:08
Add the speed1p.test script. Like speed1.test except that it tries to take advantage of prepared statements. (CVS 4907) check-in: ece4fb9f user: drh tags: trunk
01:07
Add the SQLITE_OMIT_DECLTYPE compile-time option. Remove more code when SQLITE_ENABLE_COLUMN_METADATA is not defined. (CVS 4906) check-in: 8ef26646 user: drh tags: trunk
2008-03-21
18:01
Defer allocating memory space to hold the array of column values and names in sqlite3_exec() until there is a need to use the array. In the common case where there is no callback, this avoids a malloc() call. (CVS 4905) check-in: d8686abc user: drh tags: trunk
17:29
Better integrate the new malloc related instrumentation with the test infrastructure. (CVS 4904) check-in: d2140cae user: danielk1977 tags: trunk
17:13
Make sure the text result of an aggregate function has the correct encoding. Ticket #3009. (CVS 4903) check-in: 13e388ce user: drh tags: trunk
16:45
Add a completely new testing system for the Bitvec object. The new testing system uses sqlite3_test_control() instead of unpublished APIs. Now provides 100% condition/decision coverage. Obscure bugs in Bitvec found and fixed as a result of the enhanced coverage. (CVS 4902) check-in: 2498d3ea user: drh tags: trunk
14:22
Add some more logging to the malloc system used when SQLITE_MEMDEBUG is defined. (CVS 4901) check-in: 79738f58 user: danielk1977 tags: trunk
2008-03-20
18:00
In the sqlite3_limit() interface, take out the feature where zero means use the hard upper bound. If an application wants the hard upper bound, it can set the limit to 0x7fffffff and the bound will be automatically truncated. (CVS 4900) check-in: d6be1f49 user: drh tags: trunk
16:30
Reinstate test cases for the limit tests. The sqlite3_limit() API is now tested and working. (CVS 4899) check-in: 4c4be4c3 user: drh tags: trunk
16:26
Do not run crash7.test as part of a quick test. (CVS 4898) check-in: 53b4a090 user: danielk1977 tags: trunk
14:03
Initial implementation of per-connection limits and the sqlite3_limit() API. The sqllimits1.test script crashes. SQLITE_LIMIT_PAGE_COUNT and SQLITE_LIMIT_VDBE_OP are currently ignored. (CVS 4897) check-in: 60c77882 user: drh tags: trunk
11:04
Allow a VACUUM operation to change the page-size in the same way as it can be used to change a database between auto-vacuum and normal mode. (CVS 4896) check-in: 871df0e7 user: danielk1977 tags: trunk
10:44
stick everything that sqlite links against into Libs.private (CVS 4895) check-in: 8b198617 user: vapier tags: trunk
04:45
Write the page-size into the first journal-header of each journal file. (CVS 4894) check-in: 79f573cc user: danielk1977 tags: trunk
02:25
Make out-of-tree builds work as expected when using configure script (CVS 4893) check-in: e2d05ea3 user: mlcreech tags: trunk
00:32
Fix the load-extension mechanism so that tests build with or without it. This check-in also includes prototypes for the new sqlite3_limit() interface, but no implementation. (CVS 4892) check-in: bee38c2d user: drh tags: trunk
2008-03-19
23:52
Fix build whether compiling with or without auto-extension enabled (CVS 4891) check-in: 7b9682c6 user: mlcreech tags: trunk
23:15
Don't wrongly look for the amalgamation in $(TOP) (CVS 4890) check-in: 41d6ca31 user: mlcreech tags: trunk
21:45
Add a new interface, sqlite3_context_db_handle(), that returns the database connection pointer for an application-defined function. (CVS 4889) check-in: 54c55cae user: drh tags: trunk
20:42
Undefine the "isView" macro when compiling with SQLITE_OMIT_VIEW so that the macro does not interfer with subsequent modules in the amalgamation. (CVS 4888) check-in: a42caa8f user: drh tags: trunk
20:18
Use the xCurrentTime method of the default VFS instead of stdlib time() to get the current time when compiling with SQLITE_OMIT_DATETIME_FUNCS. (CVS 4887) check-in: 73fbac7c user: drh tags: trunk
19:55
Update the loadable extension module to include recently added interfaces. (CVS 4886) check-in: bf1ceced user: drh tags: trunk
19:01
Initialize the MD5 SQL functions from test_func.c instead of using conditional compilation in tclsqlite.c. (CVS 4885) check-in: 801a0e3c user: drh tags: trunk
16:35
Create the test_destructor16() test SQL function to enhance test coverage. Prior to check-in (4883), the test_destructor() function was sufficient, but we now need separate functions since the implementation is restricted to using the published API. (CVS 4884) check-in: bb721865 user: drh tags: trunk
16:08
Move SQL functions used for testing only out of func.c and into a new test file named test_func.c. Use sqlite3_auto_extension() to make sure the test functions appear in every database connection. (CVS 4883) check-in: e90c4cc8 user: drh tags: trunk
14:15
Add a new api sqlite3_randomness() for providing access to SQLite's internal PRNG. Add sqlite3_test_control() verbs for controlling the PRNG. (CVS 4882) check-in: 15110ea0 user: drh tags: trunk
13:03
When a parse of the sqlite_master table fails, include the name of the object being parsed as part of the error message. (CVS 4881) check-in: 57805b58 user: drh tags: trunk
00:21
Remove the dependency on the direct btree interface from as many test scripts as is practical. Fix a bug in the output limiter of the integrity_check pragma that came up while making this change. (CVS 4880) check-in: 24e76997 user: drh tags: trunk
2008-03-18
13:47
Update the documentation to distinguish between protected and unprotected sqlite3_value objects. (CVS 4879) check-in: 074ee55f user: drh tags: trunk
13:46
Test script changes that go with the coverage enhancements of the previous check-in. (CVS 4878) check-in: f87ddf83 user: drh tags: trunk
13:01
Minor test coverage enhancements. (CVS 4877) check-in: edd207b9 user: drh tags: trunk
