2003-01-29

2003-01-28
23:13
First code for the new callback-free API. All regression tests pass but the new API is mostly untested and is unlikely to work. (CVS 852) check-in: 065fa818 user: drh tags: trunk
2003-01-26
15:28
Added section on comments. Corrected broken end tags. (CVS 851) check-in: c957f4f0 user: jplyon tags: trunk

14:34
Remove an unused variable. (CVS 848) check-in: 18f4ffaa user: drh tags: trunk

02:39
In the pager, cache a pointer to the first page on the freelist that does not need to be synced. This makes a fetch of a page that is not in cache go a lot faster when the cache is full. This check-in also adds some performance instrumentation to the OS layer. (CVS 842) check-in: 00f08fc0 user: drh tags: trunk
2003-01-19
03:59

2003-01-16
16:28
Add the sqlite_trace() hook for tracing the SQL that an application executes. The plan is to leave this API undocumented for the time being, in case we want to make changes to it later. (CVS 836) check-in: f67bff8f user: drh tags: trunk
13:42

19:33

18:02
Initial check-in of the code for the new sqlite_set_authorizer() API function. The code is mostly untested at this point. (CVS 827) check-in: 52d5007f user: drh tags: trunk

13:55
In the VDBE, allocate space to hold column names when the VDBE first starts. The ColumnCount opcode now just writes the null terminator into this space. (CVS 818) check-in: 46d8f5e3 user: drh tags: trunk
13:43
When constructing records and index keys, use static string space rather than mallocing (when possible) for a small speed improvement. (CVS 817) check-in: 657c9fb5 user: drh tags: trunk
02:47
More optimizations. (CVS 816) check-in: a362981b user: drh tags: trunk

18:53
Another optimization to the btree logic. (CVS 811) check-in: 03d20673 user: drh tags: trunk

Code optimizations to help the library run faster. (CVS 808) check-in: db745e87 user: drh tags: trunk
2003-01-01
23:06
If compiled with the -DVDBE_PROFILE=1 option, special code is inserted that uses the pentium RDTSC instruction to compute very precise runtimes on all VDBE opcodes. (This only works on i586 processors, of course.) The results are written into the vdbe_profile.out file for analysis. Hopefully, this new feature will reveal hot spots that can be optimized to make the VDBE run faster. (CVS 807) check-in: a1c071ea user: drh tags: trunk

2002-12-17
22:50
Version 2.7.4 (CVS 803) check-in: 0224db6f user: drh tags: trunk
