drh81a20f22001-10-12 17:30:04 +0000[diff] [blame]41<li>Bug fix: the <b>sqlite_busy_timeout()</b> function was delaying 1000
42 times too long before failing.</li>
43<li>Bug fix: an assertion was failing if the disk holding the database
44 file became full or stopped accepting writes for some other reason.
45 New tests were added to detect similar problems in the future.</li>
drhbf4133c2001-10-13 02:59:08 +0000[diff] [blame]46<li>Added new operators: <b>&amp;</b> (bitwise-and)

drh382c0242001-10-06 16:33:02 +0000[diff] [blame]54<li>Removed some unused "#include <unistd.h>" that were causing problems
55 for VC++.</li>
drhf57b3392001-10-08 13:22:32 +0000[diff] [blame]56<li>Fixed <b>sqlite.h</b> so that it is usable from C++</li>
drh382c0242001-10-06 16:33:02 +0000[diff] [blame]57<li>Added the FULL_COLUMN_NAMES pragma. When set to "ON", the names of
58 columns are reported back as TABLE.COLUMN instead of just COLUMN.</li>
drhad75e982001-10-09 04:19:46 +0000[diff] [blame]59<li>Added the TABLE_INFO() and INDEX_INFO() pragmas to help support the

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

drhb19a2bc2001-09-16 00:13:26 +0000[diff] [blame]93<li>Initial release of version 2.0. The idea of renaming the library
94 to "SQLus" was abandoned in favor of keeping the "SQLite" name and
95 bumping the major version number.</li>
96<li>The pager and btree subsystems added back. They are now the only
97 available backend.</li>

drh6f63c252001-04-05 16:25:53 +0000[diff] [blame]126<li>The library now assumes data is stored as UTF-8 if the --enable-utf8
127 option is given to configure. The default behavior is to assume
128 iso8859-x, as it has always done. This only makes a difference for
129 LIKE and GLOB operators and the LENGTH and SUBSTR functions.</li>
130<li>If the library is not configured for UTF-8 and the Tcl library
131 is one of the newer ones that uses UTF-8 internally,
132 then a conversion from UTF-8 to iso8859 and
drh297ecf12001-04-05 15:57:13 +0000[diff] [blame]133 back again is done inside the TCL interface.</li>

137<li>Added limited support for transactions. At this point, transactions
138 will do table locking on the GDBM backend. There is no support (yet)
139 for rollback or atomic commit.</li>
140<li>Added special column names ROWID, OID, and _ROWID_ that refer to the
141 unique random integer key associated with every row of every table.</li>
142<li>Additional tests added to the regression suite to cover the new ROWID
143 feature and the TCL interface bugs mentioned below.</li>
drh960e8c62001-04-03 16:53:21 +0000[diff] [blame]144<li>Changes to the "lemon" parser generator to help it work better when

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

164<li>Modify the test scripts to identify tests that depend on system
165 load and processor speed and
166 to warn the user that a failure of one of those (rare) tests does
167 not necessarily mean the library is malfunctioning. No changes to
168 code.

drhb8525d92001-03-14 12:54:11 +0000[diff] [blame]174 the UPDATE command to fail on systems where "malloc(0)" returns
drhb0729502001-03-14 12:35:57 +0000[diff] [blame]175 NULL. The problem does not appear Windows, Linux, or HPUX but does
176 cause the library to fail on QNX.

182 for figuring out where to put temporary files for a "memory:" database
183 was not working quite right.

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

200 using a BTree file structure will use a separate CVS source tree. This
201 CVS tree will continue to support the GDBM version of SQLite only.</li>
