102 newlines anywhere in the data. This is an old bug that was carried
103 forward from version 1.0. To fix it, the ".dump" output no longer
104 uses the COPY command. It instead generates INSERT statements.</li>

106 space between the "NOT" and the "NULL") in addition to "expr NOTNULL"
107 (with no space).</li>

drh6f63c252001-04-05 16:25:53 +0000[diff] [blame]160<li>The library now assumes data is stored as UTF-8 if the --enable-utf8
161 option is given to configure. The default behavior is to assume
162 iso8859-x, as it has always done. This only makes a difference for
163 LIKE and GLOB operators and the LENGTH and SUBSTR functions.</li>
164<li>If the library is not configured for UTF-8 and the Tcl library
165 is one of the newer ones that uses UTF-8 internally,
166 then a conversion from UTF-8 to iso8859 and
drh297ecf12001-04-05 15:57:13 +0000[diff] [blame]167 back again is done inside the TCL interface.</li>

172 will do table locking on the GDBM backend. There is no support (yet)
173 for rollback or atomic commit.</li>
174<li>Added special column names ROWID, OID, and _ROWID_ that refer to the
175 unique random integer key associated with every row of every table.</li>
176<li>Additional tests added to the regression suite to cover the new ROWID
177 feature and the TCL interface bugs mentioned below.</li>

185 numbers of records to be deleted or updated into a temporary file.
186 This is changed so that the record numbers are held in memory.</li>
187<li>The DELETE command without a WHILE clause just removes the database
188 files from the disk, rather than going through and deleting record
189 by record.</li>

199 load and processor speed and
200 to warn the user that a failure of one of those (rare) tests does
201 not necessarily mean the library is malfunctioning. No changes to
202 code.
