[Phpmyadmin-devel] Server status Monitor: Query Analyzer Dialog
by Tyron Madlener 21 Jul '11

21 Jul '11

Just some news about my progress: I've spent the last few days fiddling around with regular expressions and dialogs to add another feature which I called 'Query Analyzer', here's an example screenshot: http://www.tyron.at/tmp/query_analyzer.png You can reach this dialog by going to the Monitor Tab, start the monitoring, retrieve some log data (need to enable stuff in setup first), then click on a select statement in the resulting table. I've added some very basic sql formatter to pretty-print the sql query inside an codemirror textarea, so one can fiddle with the query and re-analyze it. Current "bugs": - Parts of the formatted query in the textarea are sometimes white, making them unreadable. Selecting and deselecting fixes it. Looks like a codemirror bug to me. - l10n is incomplete for the query analyzer feature. Further plans: - Analyzed queries are always executed with SQL_NO_CACHE, probably should mention that somewhere - Displaying 'affected rows' probably would be useful - Add some sort of interpretation / advisories on the results, like following performance issues: - 'Using filesort', 'Using temporary' in Explain->Extra - Long query execution time - 'ALL' in explain->type (= full table scan) - Suggestions from you guys ;-) Other things I did this week: - Invested a lot of time in a new log table filter "Group queries, ignoring variable data in WHERE statements" which uses regexps to remove variable data in WHERE statements, so that they can be grouped together, allowing one to see how much similar queries are being executed. - Fixed some bugs with the 'count' column in the log table. Feedback is very welcome.

Hi You again missed reply to list, moving discussion back there :-).

Isn't that a bit overkill? Not every page (like my > status page) requires codemirror. I don't think it hurts that much (browser should have that file in cache), generally I was too lazy to figure out in which all places SQL box needing highlighting might appear. -- Michal Čihař | http://cihar.com | http://phpmyadmin.cz

[Phpmyadmin-devel] problem with column dragging
by Marc Delisle 19 Jul '11

19 Jul '11

Tyron, could you have a look at your commit a5df22ced5067260b5edbb3d95b83cc8050d21a9 ? In my tests, this commit breaks column dragging. For example, in sakila.actor, try to drag actor_id to the rightmost position. -- Marc Delisle http://infomarc.info

[Phpmyadmin-devel] Better chart reordering for monitor tab
by Tyron Madlener 18 Jul '11

18 Jul '11

Just built a reusable jquery plugin for elegant reordering of table cells. I will be using it for the Monitor Tab as it greatly improves the usability of chart reordering (mainly because I want the user to select a column width and have automatic chart size, instead of setting a chart size and have automatic column width): http://www.tyron.at/tmp/ts.html There is still a bug when an element is dropped before the 'preview animation' is over (200ms). But apart from that it's kinda fun to play with, thus I'm posting it here ;-)

[Phpmyadmin-devel] Unit testing
by Michal Čihař 18 Jul '11

18 Jul '11

Hi all (and especially Zarubin :-)) I started to setup testing server, however I'm somehow stuck. I followed http://wiki.phpmyadmin.net/pma/TestingEnvironment and I believe I have all components in place. However running all tests is something I can not manage. http://wiki.phpmyadmin.net/pma/UnitTesting mentions some configuration files, but no matter what I try, the tests are not run. Running single test seems to work: $ phpunit test/libraries/core/PMA_isValid_test.php PHPUnit 3.5.5 by Sebastian Bergmann. PMA_isValid_test testNoVarType ............ .................... testSimilarType ...... . Time: 0 seconds, Memory: 8.25Mb OK (39 tests, 68 assertions) Writing code coverage data to XML file, this may take a moment. Generating code coverage report, this may take a moment. However there seems to be wrong configuration somewhere using backslashes instead of slashes so it creates files like build\logs\junit.xml -- Michal Čihař | http://cihar.com | http://blog.cihar.com

[Phpmyadmin-devel] XML export
by Piotr Przybylski 15 Jul '11

15 Jul '11

Hi, Is XML export used at all? It was missing data escaping in many places, and structure (table, function, ...) export was just broken. I fixed it a bit, but there are still some problems that remain: - escaping of table/db names and data in other encodings than ISO-8859-1 - it uses SHOW CREATE TABLE without any required fixes File format itself is interesting. I don't expect XML Schema for it to exist, but at least namespace usage should be consistent. I think fixing this and rewriting output format to be more consistent should appear on Tasks for junior developers. And maybe extending it to output data in more concise format, eg.: <table name=""> <row> <column_name>value</column_name> ... </row> ... </table> -- Regards, Piotr Przybylski
