21<li>Pager subsystem added but not yet used.</li>
drhdaffd0e2001-04-11 14:28:42 +000022<li>More robust handling of out-of-memory errors.</li>
drhd1bf3512001-04-07 15:24:33 +000023<li>New tests added to the test suite.</li>
24}

drh818041a2001-04-06 16:15:27 +000026chng {2001 Apr 6 (1.0.30)} {
27<li>Remove the <b>sqlite_encoding</b> TCL variable that was introduced
28 in the previous version.</li>
29<li>Add options <b>-encoding</b> and <b>-tcl-uses-utf</b> to the
30 <b>sqlite</b> TCL command.</li>
31<li>Add tests to make sure that tclsqlite was compiled using Tcl header
32 files and libraries that match.</li>
33}

drhe17a7e32001-04-04 21:10:18 +000035chng {2001 Apr 5 (1.0.29)} {
drh6f63c252001-04-05 16:25:53 +000036<li>The library now assumes data is stored as UTF-8 if the --enable-utf8
37 option is given to configure. The default behavior is to assume
38 iso8859-x, as it has always done. This only makes a difference for
39 LIKE and GLOB operators and the LENGTH and SUBSTR functions.</li>
40<li>If the library is not configured for UTF-8 and the Tcl library
41 is one of the newer ones that uses UTF-8 internally,
42 then a conversion from UTF-8 to iso8859 and
drh297ecf12001-04-05 15:57:13 +000043 back again is done inside the TCL interface.</li>
drhe17a7e32001-04-04 21:10:18 +000044}
45
drhc4a3c772001-04-04 11:48:57 +000046chng {2001 Apr 4 (1.0.28)} {
47<li>Added limited support for transactions. At this point, transactions
48 will do table locking on the GDBM backend. There is no support (yet)
49 for rollback or atomic commit.</li>
50<li>Added special column names ROWID, OID, and _ROWID_ that refer to the
51 unique random integer key associated with every row of every table.</li>
52<li>Additional tests added to the regression suite to cover the new ROWID
53 feature and the TCL interface bugs mentioned below.</li>
drh960e8c62001-04-03 16:53:21 +000054<li>Changes to the "lemon" parser generator to help it work better when
55 compiled using MSVC.</li>
56<li>Bug fixes in the TCL interface identified by Oleg Oleinick.</li>
57}

drh0353ced2001-03-20 22:05:00 +000059chng {2001 Mar 20 (1.0.27)} {
60<li>When doing DELETE and UPDATE, the library used to write the record
61 numbers of records to be deleted or updated into a temporary file.
62 This is changed so that the record numbers are held in memory.</li>
63<li>The DELETE command without a WHILE clause just removes the database
64 files from the disk, rather than going through and deleting record
65 by record.</li>
66}
67
drh3494ffe2001-03-20 12:55:13 +000068chng {2001 Mar 20 (1.0.26)} {
69<li>A serious bug fixed on Windows. Windows users should upgrade.
70 No impact to Unix.</li>
71}
72
drhdb25e382001-03-15 18:21:22 +000073chng {2001 Mar 15 (1.0.25)} {
74<li>Modify the test scripts to identify tests that depend on system
75 load and processor speed and
76 to warn the user that a failure of one of those (rare) tests does
77 not necessarily mean the library is malfunctioning. No changes to
78 code.
79 </li>
80}
81
82chng {2001 Mar 14 (1.0.24)} {
83<li>Fix a bug which was causing
drhb8525d92001-03-14 12:54:11 +000084 the UPDATE command to fail on systems where "malloc(0)" returns
drhb0729502001-03-14 12:35:57 +000085 NULL. The problem does not appear Windows, Linux, or HPUX but does
86 cause the library to fail on QNX.
87 </li>
88}
89
drhe53dea12001-02-19 23:48:16 +000090chng {2001 Feb 19 (1.0.23)} {
91<li>An unrelated (and minor) bug from Mark Muranwski fixed. The algorithm
92 for figuring out where to put temporary files for a "memory:" database
93 was not working quite right.
94 </li>
95}

103<li>The UPDATE statement was not working when the WHERE clause contained
104 some terms that could be satisfied using indices and other terms that
105 could not. Fixed.</li>
106}
107
drh338ea132001-02-11 16:56:24 +0000108chng {2001 Feb 11 (1.0.20)} {
109<li>Merge development changes into the main trunk. Future work toward
110 using a BTree file structure will use a separate CVS source tree. This
111 CVS tree will continue to support the GDBM version of SQLite only.</li>
112}
113
114chng {2001 Feb 6 (1.0.19)} {
115<li>Fix a strange (but valid) C declaration that was causing problems

128<li>Minor tweaks to other code to make it run a little faster.</li>
129<li>Added new tests for <b>sqlite_complete()</b> and for memory leaks.</li>
130}

137<li>Documentation updates</li>
138<li>Some sanity checking code was removed from the inner loop of vdbe.c
139 to help the library to run a little faster. The code is only
140 removed if you compile with -DNDEBUG.</li>
141}

145 in-memory hash table.</li>

drhbb0b6792000-10-19 01:49:02 +0000148chng {2000 Oct 18 (1.0.13)} {
149<li>Break out the GDBM driver into a separate file in anticipation
150 to added new drivers.</li>
151<li>Allow the name of a database to be prefixed by the driver type.
drh8c82b352000-12-10 18:23:50 +0000152 For now, the only driver type is "gdbm:".</li>

drh4c504392000-10-16 22:06:40 +0000159<li>Added the <b>sqlite_interrupt()</b> interface.</li>

187 sqlite_get_table() API in order to print a list of tables
188 in multiple columns, similar to the way "ls" prints filenames.</li>
189<li>Modified the <b>sqlite</b> shell to print a semicolon at the
190 end of each CREATE statement in the output of the ".schema" command.</li>

220<li>Bug fix: incorrect VDBE code was being generated for the following
221 circumstance: a query on an indexed table containing a WHERE clause with
222 an IN operator that had a subquery on its right-hand side.</li>
drh80afdca2000-08-22 13:27:22 +0000223}

256<li>The file format for indices was changed slightly in order to work
257 around an inefficiency that can sometimes come up with GDBM when
258 there are large indices having many entries with the same key.
259 <font color="red">** Incompatible Change **</font></li>

drhe91cd0c2000-06-12 12:36:36 +0000302<li>Added the fcnt() function to the SQL interpreter. The fcnt() function
303 returns the number of database "Fetch" operations that have occurred.
304 This function is designed for use in test scripts to verify that
305 queries are efficient and appropriately optimized. Fcnt() has no other
306 useful purpose, as far as I know.</li>

358and '_' wildcards of SQL.</li>
359<li>Added the <B>COPY</b> command patterned after
