drhad75e982001-10-09 04:19:46 +000021<li>Fix a bugs in the locking protocol.</li>
drh382c0242001-10-06 16:33:02 +000022<li>Removed some unused "#include <unistd.h>" that were causing problems
23 for VC++.</li>
drhf57b3392001-10-08 13:22:32 +000024<li>Fixed <b>sqlite.h</b> so that it is usable from C++</li>
drh382c0242001-10-06 16:33:02 +000025<li>Added the FULL_COLUMN_NAMES pragma. When set to "ON", the names of
26 columns are reported back as TABLE.COLUMN instead of just COLUMN.</li>
drhad75e982001-10-09 04:19:46 +000027<li>Added the TABLE_INFO() and INDEX_INFO() pragmas to help support the
28 ODBC interface.</li>
drhf57b3392001-10-08 13:22:32 +000029<li>Added support for TEMPORARY tables and indices.</li>

33<li>Remove some C++ style comments from btree.c so that it will compile
34 using compilers other than gcc.</li>
drh33048c02001-10-01 14:29:22 +000035<li>The ".dump" output from the shell does not work if there are embedded
36 newlines anywhere in the data. This is an old bug that was carried
37 forward from version 1.0. To fix it, the ".dump" output no longer
38 uses the COPY command. It instead generates INSERT statements.</li>
39<li>Extend the expression syntax to support "expr NOT NULL" (with a
40 space between the "NOT" and the "NULL") in addition to "expr NOTNULL"
41 (with no space).</li>

drh60c309b2001-09-27 15:13:40 +000055 keys are required to be unique.</li>
56<li>File format changed back to what it was for alpha-1</li>

drhb19a2bc2001-09-16 00:13:26 +000061<li>Initial release of version 2.0. The idea of renaming the library
62 to "SQLus" was abandoned in favor of keeping the "SQLite" name and
63 bumping the major version number.</li>
64<li>The pager and btree subsystems added back. They are now the only
65 available backend.</li>
66<li>The Dbbe abstraction and the GDBM and memory drivers were removed.</li>
67<li>Copyright on all code was disclaimed. The library is now in the
68 public domain.</li>

75 expressions.</li>

drhdaffd0e2001-04-11 14:28:42 +000080<li>More robust handling of out-of-memory errors.</li>
drhd1bf3512001-04-07 15:24:33 +000081<li>New tests added to the test suite.</li>

90 files and libraries that match.</li>

drh6f63c252001-04-05 16:25:53 +000094<li>The library now assumes data is stored as UTF-8 if the --enable-utf8
95 option is given to configure. The default behavior is to assume
96 iso8859-x, as it has always done. This only makes a difference for
97 LIKE and GLOB operators and the LENGTH and SUBSTR functions.</li>
98<li>If the library is not configured for UTF-8 and the Tcl library
99 is one of the newer ones that uses UTF-8 internally,
100 then a conversion from UTF-8 to iso8859 and
drh297ecf12001-04-05 15:57:13 +0000101 back again is done inside the TCL interface.</li>

drhc4a3c772001-04-04 11:48:57 +0000104chng {2001 Apr 4 (1.0.28)} {
105<li>Added limited support for transactions. At this point, transactions
106 will do table locking on the GDBM backend. There is no support (yet)
107 for rollback or atomic commit.</li>
108<li>Added special column names ROWID, OID, and _ROWID_ that refer to the
109 unique random integer key associated with every row of every table.</li>
110<li>Additional tests added to the regression suite to cover the new ROWID
111 feature and the TCL interface bugs mentioned below.</li>
drh960e8c62001-04-03 16:53:21 +0000112<li>Changes to the "lemon" parser generator to help it work better when
113 compiled using MSVC.</li>
114<li>Bug fixes in the TCL interface identified by Oleg Oleinick.</li>

drh0353ced2001-03-20 22:05:00 +0000117chng {2001 Mar 20 (1.0.27)} {
118<li>When doing DELETE and UPDATE, the library used to write the record
119 numbers of records to be deleted or updated into a temporary file.
120 This is changed so that the record numbers are held in memory.</li>
121<li>The DELETE command without a WHILE clause just removes the database
122 files from the disk, rather than going through and deleting record
123 by record.</li>
124}

drh3494ffe2001-03-20 12:55:13 +0000126chng {2001 Mar 20 (1.0.26)} {

drhdb25e382001-03-15 18:21:22 +0000131chng {2001 Mar 15 (1.0.25)} {
132<li>Modify the test scripts to identify tests that depend on system
133 load and processor speed and
134 to warn the user that a failure of one of those (rare) tests does
135 not necessarily mean the library is malfunctioning. No changes to
136 code.
137 </li>
138}

140chng {2001 Mar 14 (1.0.24)} {
141<li>Fix a bug which was causing
drhb8525d92001-03-14 12:54:11 +0000142 the UPDATE command to fail on systems where "malloc(0)" returns
drhb0729502001-03-14 12:35:57 +0000143 NULL. The problem does not appear Windows, Linux, or HPUX but does
144 cause the library to fail on QNX.
145 </li>

149<li>An unrelated (and minor) bug from Mark Muranwski fixed. The algorithm
150 for figuring out where to put temporary files for a "memory:" database
151 was not working quite right.
152 </li>

161<li>The UPDATE statement was not working when the WHERE clause contained
162 some terms that could be satisfied using indices and other terms that
163 could not. Fixed.</li>

drh338ea132001-02-11 16:56:24 +0000166chng {2001 Feb 11 (1.0.20)} {
167<li>Merge development changes into the main trunk. Future work toward
168 using a BTree file structure will use a separate CVS source tree. This
169 CVS tree will continue to support the GDBM version of SQLite only.</li>
170}
171

drhe91cd0c2000-06-12 12:36:36 +0000360<li>Added the fcnt() function to the SQL interpreter. The fcnt() function
361 returns the number of database "Fetch" operations that have occurred.
362 This function is designed for use in test scripts to verify that
363 queries are efficient and appropriately optimized. Fcnt() has no other
364 useful purpose, as far as I know.</li>
365<li>Added a bunch more tests that take advantage of the new fcnt() function.
