22 SQL server library named "SQLus".</li>
23<li>Add the ability to use quoted strings as table and column names in

drhdaffd0e2001-04-11 14:28:42 +0000[diff] [blame]29<li>More robust handling of out-of-memory errors.</li>

35 in the previous version.</li>
36<li>Add options <b>-encoding</b> and <b>-tcl-uses-utf</b> to the

39 files and libraries that match.</li>

drh6f63c252001-04-05 16:25:53 +0000[diff] [blame]43<li>The library now assumes data is stored as UTF-8 if the --enable-utf8
44 option is given to configure. The default behavior is to assume
45 iso8859-x, as it has always done. This only makes a difference for
46 LIKE and GLOB operators and the LENGTH and SUBSTR functions.</li>
47<li>If the library is not configured for UTF-8 and the Tcl library
48 is one of the newer ones that uses UTF-8 internally,
49 then a conversion from UTF-8 to iso8859 and
drh297ecf12001-04-05 15:57:13 +0000[diff] [blame]50 back again is done inside the TCL interface.</li>

54<li>Added limited support for transactions. At this point, transactions
55 will do table locking on the GDBM backend. There is no support (yet)
56 for rollback or atomic commit.</li>
57<li>Added special column names ROWID, OID, and _ROWID_ that refer to the
58 unique random integer key associated with every row of every table.</li>
59<li>Additional tests added to the regression suite to cover the new ROWID
60 feature and the TCL interface bugs mentioned below.</li>
drh960e8c62001-04-03 16:53:21 +0000[diff] [blame]61<li>Changes to the "lemon" parser generator to help it work better when
62 compiled using MSVC.</li>
63<li>Bug fixes in the TCL interface identified by Oleg Oleinick.</li>

67<li>When doing DELETE and UPDATE, the library used to write the record
68 numbers of records to be deleted or updated into a temporary file.
69 This is changed so that the record numbers are held in memory.</li>
70<li>The DELETE command without a WHILE clause just removes the database
71 files from the disk, rather than going through and deleting record
72 by record.</li>

81<li>Modify the test scripts to identify tests that depend on system
82 load and processor speed and
83 to warn the user that a failure of one of those (rare) tests does
84 not necessarily mean the library is malfunctioning. No changes to
85 code.
86 </li>

90<li>Fix a bug which was causing
drhb8525d92001-03-14 12:54:11 +0000[diff] [blame]91 the UPDATE command to fail on systems where "malloc(0)" returns
drhb0729502001-03-14 12:35:57 +0000[diff] [blame]92 NULL. The problem does not appear Windows, Linux, or HPUX but does
93 cause the library to fail on QNX.

98<li>An unrelated (and minor) bug from Mark Muranwski fixed. The algorithm
99 for figuring out where to put temporary files for a "memory:" database
100 was not working quite right.
101 </li>
102}

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

116<li>Merge development changes into the main trunk. Future work toward
117 using a BTree file structure will use a separate CVS source tree. This
118 CVS tree will continue to support the GDBM version of SQLite only.</li>
119}

341<li>All database files to be modified by an UPDATE, INSERT or DELETE are
342now locked before any changes are made to any files.
343This makes it safe (I think) to access
344the same database simultaneously from multiple processes.</li>
345<li>The code appears stable so we are now calling it "beta".</li>

349<li>Better support for file locking so that two or more processes
350(or threads)
351can access the same database simultaneously. More work needed in
352this area, though.</li>

365and '_' wildcards of SQL.</li>
366<li>Added the <B>COPY</b> command patterned after
367<a href="http://www.postgresql.org/">PostgreSQL</a> so that SQLite
368can now read the output of the <b>pg_dump</b> database dump utility
369of PostgreSQL.</li>
370<li>Added a <B>VACUUM</B> command that that calls the
371<b>gdbm_reorganize()</b> function on the underlying database
