21<li>Modify the test scripts to identify tests that depend on system
22 load and processor speed and
23 to warn the user that a failure of one of those (rare) tests does
24 not necessarily mean the library is malfunctioning. No changes to
25 code.

30<li>Fix a bug which was causing
drhb8525d92001-03-14 12:54:11 +0000[diff] [blame]31 the UPDATE command to fail on systems where "malloc(0)" returns
drhb0729502001-03-14 12:35:57 +0000[diff] [blame]32 NULL. The problem does not appear Windows, Linux, or HPUX but does
33 cause the library to fail on QNX.
34 </li>

38<li>An unrelated (and minor) bug from Mark Muranwski fixed. The algorithm
39 for figuring out where to put temporary files for a "memory:" database
40 was not working quite right.
41 </li>
42}

51 some terms that could be satisfied using indices and other terms that
52 could not. Fixed.</li>

56<li>Merge development changes into the main trunk. Future work toward
57 using a BTree file structure will use a separate CVS source tree. This
58 CVS tree will continue to support the GDBM version of SQLite only.</li>
59}

84<li>Documentation updates</li>
85<li>Some sanity checking code was removed from the inner loop of vdbe.c

87 removed if you compile with -DNDEBUG.</li>

drhe91cd0c2000-06-12 12:36:36 +0000[diff] [blame]249<li>Added the fcnt() function to the SQL interpreter. The fcnt() function
250 returns the number of database "Fetch" operations that have occurred.
251 This function is designed for use in test scripts to verify that
252 queries are efficient and appropriately optimized. Fcnt() has no other
253 useful purpose, as far as I know.</li>
