On a postgres-based install (UTF-8 encoding), the database barfs on binary values for the math_inputhash and math_outputhash columns in the SQL, reporting invalid UTF-8 chars; the byte arrays need to be escaped with pg_escape_bytea() A database error has occurred Query: SELECT math_outputhash,math_html_conservativeness,math_html,math_mathml FROM math WHERE math_inputhash = '� |(�ɖ�e�\\�' LIMIT 1 Function: MathRenderer::_recall Error: 1 ERROR: invalid byte sequence for encoding "UTF8": 0xce0d Backtrace: #0 /storage/www/htdocs/wiki/includes/Database.php(761): DatabasePostgres->reportQueryError('ERROR: invalid...', 1, 'SELECT math_ou...', 'MathRenderer::_...', false) #1 /storage/www/htdocs/wiki/includes/Database.php(1179): Database->query('SELECT math_ou...', 'MathRenderer::_...') #2 /storage/www/htdocs/wiki/includes/Database.php(1198): Database->select('math', Array, Array, 'MathRenderer::_...', Array) #3 /storage/www/htdocs/wiki/includes/Math.php(191): Database->selectRow('math', Array, Array, 'MathRenderer::_...') #4 /storage/www/htdocs/wiki/includes/Math.php(44): MathRenderer->_recall() #5 /storage/www/htdocs/wiki/includes/Math.php(269): MathRenderer->render() #6 /storage/www/htdocs/wiki/includes/Parser.php(590): MathRenderer::renderMath('Insert formula ...') #7 /storage/www/htdocs/wiki/includes/Parser.php(300): Parser->strip('This section de...', Object(StripState)) #8 /storage/www/htdocs/wiki/includes/Article.php(2289): Parser->parse('This section de...', Object(Title), Object(ParserOptions), true, true, 30) #9 /storage/www/htdocs/wiki/includes/Article.php(1380): Article->editUpdates('This section de...', '', true, '20070514154832', 30, false) #10 /storage/www/htdocs/wiki/includes/Article.php(1205): Article->doEdit('This section de...', '', 102) #11 /storage/www/htdocs/wiki/includes/EditPage.php(865): Article->updateArticle('This section de...', '', true, false, '', '') #12 /storage/www/htdocs/wiki/includes/EditPage.php(426): EditPage->attemptSave() #13 /storage/www/htdocs/wiki/includes/EditPage.php(279): EditPage->edit() #14 /storage/www/htdocs/wiki/includes/Wiki.php(432): EditPage->submit() #15 /storage/www/htdocs/wiki/includes/Wiki.php(48): MediaWiki->performAction(Object(OutputPage), Object(Article), Object(Title), Object(User), Object(WebRequest)) #16 /storage/www/htdocs/wiki/index.php(89): MediaWiki->initialize(Object(Title), Object(OutputPage), Object(User), Object(WebRequest)) #17 {main}
blocks bug 384
Patch applied in r22832. Thanks for the report. Someday, we'll flip those fields back to simple text and not do all that pack() and unpack().
Just a note for other people trying to fix this in their installations: The patch above will *not* work for version 1.10.1 because encodeBlob returns an array in this version. In SVN trunk it only returns the encoded value. So you need to extract the second value from the array you get from encodeBlob and then pass this on to the database functions.
