21<li>Fix the locking mechanism yet again to prevent
22 <b>sqlite_exec()</b> from returning SQLITE_PROTOCOL
23 unnecessarily. This time the bug was a race condition in
24 the locking code. This change effects both POSIX and Windows users.</li>

28<li>Fix for another problem (unrelated to the one fixed in 2.1.4)
29 that sometimes causes <b>sqlite_exec()</b> to return SQLITE_PROTOCOL
30 unnecessarily. This time the bug was
31 in the POSIX locking code and should not effect windows users.</li>

38 fixed.</li>

46 (ex: "<b>&lt</b>", "<b>==</b>", etc.)
47 so that they are consistent with the order of entries in an index.</li>

drhf5bf0a72001-11-23 00:24:12 +000055<li>Fix a bug that could (rarely) cause the database to become
56 unreadable after a DROP TABLE due to corruption to the SQLITE_MASTER
57 table.</li>
58<li>Change the code so that version 2.1.1 databases that were rendered
59 unreadable by the above bug can be read by this version of
60 the library even though the SQLITE_MASTER table is (slightly)
61 corrupted.</li>

90 fix a bug in the round() function.</li>
91<li>Plug some memory leaks that use to occur if malloc() failed.
92 We have been and continue to be memory leak free as long as
93 malloc() works.</li>
94<li>Changes to some test scripts so that they work on Windows in
95 addition to Unix.</li>

121<li>Bug fix: an assertion was failing if the disk holding the database
122 file became full or stopped accepting writes for some other reason.
123 New tests were added to detect similar problems in the future.</li>
drhbf4133c2001-10-13 02:59:08 +0000124<li>Added new operators: <b>&amp;</b> (bitwise-and)

drh382c0242001-10-06 16:33:02 +0000132<li>Removed some unused "#include <unistd.h>" that were causing problems
133 for VC++.</li>
drhf57b3392001-10-08 13:22:32 +0000134<li>Fixed <b>sqlite.h</b> so that it is usable from C++</li>
drh382c0242001-10-06 16:33:02 +0000135<li>Added the FULL_COLUMN_NAMES pragma. When set to "ON", the names of

drhad75e982001-10-09 04:19:46 +0000137<li>Added the TABLE_INFO() and INDEX_INFO() pragmas to help support the

146 newlines anywhere in the data. This is an old bug that was carried
147 forward from version 1.0. To fix it, the ".dump" output no longer
148 uses the COPY command. It instead generates INSERT statements.</li>
149<li>Extend the expression syntax to support "expr NOT NULL" (with a
150 space between the "NOT" and the "NULL") in addition to "expr NOTNULL"
151 (with no space).</li>

drhb19a2bc2001-09-16 00:13:26 +0000171<li>Initial release of version 2.0. The idea of renaming the library
172 to "SQLus" was abandoned in favor of keeping the "SQLite" name and
173 bumping the major version number.</li>
174<li>The pager and btree subsystems added back. They are now the only
175 available backend.</li>

205 option is given to configure. The default behavior is to assume
206 iso8859-x, as it has always done. This only makes a difference for
207 LIKE and GLOB operators and the LENGTH and SUBSTR functions.</li>
208<li>If the library is not configured for UTF-8 and the Tcl library
209 is one of the newer ones that uses UTF-8 internally,
210 then a conversion from UTF-8 to iso8859 and
drh297ecf12001-04-05 15:57:13 +0000211 back again is done inside the TCL interface.</li>

215<li>Added limited support for transactions. At this point, transactions
216 will do table locking on the GDBM backend. There is no support (yet)
217 for rollback or atomic commit.</li>
218<li>Added special column names ROWID, OID, and _ROWID_ that refer to the
219 unique random integer key associated with every row of every table.</li>
220<li>Additional tests added to the regression suite to cover the new ROWID
221 feature and the TCL interface bugs mentioned below.</li>
drh960e8c62001-04-03 16:53:21 +0000222<li>Changes to the "lemon" parser generator to help it work better when

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

243 load and processor speed and

245 not necessarily mean the library is malfunctioning. No changes to
246 code.

drhb0729502001-03-14 12:35:57 +0000253 NULL. The problem does not appear Windows, Linux, or HPUX but does
