Change the way the "crash" VFS (test6.c) handles SQLITE_FCNTL_SIZE_HINT. check-in: 40dd8a60 user: dan tags: trunk
16:41
Have the "crash" VFS used by the tcl tests (test6.c) handle SQLITE_FCNTL_SIZE_HINT internally, instead of passing it directly through to the underlying VFS.

14:41
When opening a temporary file to use in a merge-sort, pass SQLITE_OPEN_TEMP_JOURNAL instead of SQLITE_OPEN_TEMP_DB. This is a better fit, as merge-sort files are written and read sequentially like journal files. check-in: bd04756b user: dan tags: trunk

Add command-line utilities "offsets.c" and "extract.c" for use in low-level analyzsis of database files. check-in: dfa22ed4 user: drh tags: trunk
2011-08-08
23:48
In os_unix.c, do not open the directory containing the database file when the database file is opened. Instead, wait until time to fsync() the directory. And do not report an error if the open fails, since some systems (Ex: AIX and a chromium sandbox) are unable to open and fsync directories. check-in: 713b1b7d user: drh tags: trunk

The ANALYZE command adds the sqlite_stat2.cnt column if it does not already exist. check-in: 794fde6f user: drh tags: query-planner-tweaks
2011-08-06
19:48
The sqlite_stat2.cnt field is parsed if it is present. But it is not yet used. A large comment added to analyze.c to explain the format of the ANALYZE system tables. check-in: 6d1e2372 user: drh tags: query-planner-tweaks
