[Phpmyadmin-devel] Table charting pChart replacement
by Tyron Madlener 15 Jun '11

15 Jun '11

Wasn't sure of whether to mail this to Michal or the mailing list, but I guess a bigger audience also means more feedback :) I am in the process of replacing pChart in pma and finishing on the table charting feature. Since the pChart-Version was rather difficult to use I thought I'd offer the user some choice about which column data is used for what. While implementing, I was orienting in the examples given by http://wiki.phpmyadmin.net/pma/Charts#Data_formats_for_query_results_chart where I was slightly surprised by the odd data format of the examples. It doesn't allow any graph with more than 2 series. So I thought the most logical of way representing table data is by selecting one column as x-axis and let the other columns be different series within the graph. So looking at the examples, the logical continuation of example 2 would be: SELECT 225 AS 'Value1', 653 AS 'Value2', '2009-11' AS 'Month' UNION SELECT 1157, 855, '2009-12' UNION SELECT 569, 253, '2010-01' UNION SELECT 282, 455, '2010-02' UNION SELECT 2960, 3552, '2010-03' ...which will display the date on the X-Axis and 2 series (Value1 and Value2) in the graph. However, in order to allow data like in the original example3 I've added a select list where one can select what the series types should be. The default selection is to use all columns except the selected xaxis but you can also select a specific column from where it should read all possible types (so this column should probably be a ENUM or similar). So when charting the original example3 with Type set to Column, Series=Operator, X-Axis=Month and Stacking on we get the same result again. I'm not quite sure whether such solution will make sense for everyone so I'm asking here if it is :-) Current differences over the pChart implementation: - Everything updates as you type/select. No more Redraw button is required - New charting types: (Horizontal-)Bar and Spline - No editable Area/Legend Margins (who needs that?) - Have as many Series (=Columns-1) as you want, not only 3 - Select the column you want to be the x-axis, so you don't need to know by heart where in your query result the x-axis column is supposed to be. - If a column contains the word date or time it will be pre-selected as xaxis - No width/height selection, instead just mouse-drag the chart to the right size. Please check it out at http://demo.phpmyadmin.net/gsoc-tyron/ P.S.: There seems to be a problem when using the sql statements given on the wiki within the db links SQL page. Once the query is executed and you click on display chart or export it just redirects you to the main page again.

[Phpmyadmin-devel] First day of GSoC work
by Rouslan Placella 14 Jun '11

14 Jun '11

Hi there, I started coding for GSoC yesterday, since I need Monday off for a college exam. I pushed the changes that I did to my repo [1], and they are available for you to try on my demo server [2] (There are some routines and triggers in the sakila db, but you'll have to add your own events). Well, first of all I'd appreciate any feedback from you guys regarding what I did. Which was: adding tabs for routines, triggers, events; moving there the functionality that was already available; getting export and drop options to work properly. However I have a problem with the "Drop" option that doesn't redirect the user back to where he came from after deleting the requested object. I tried adding a "goto" variable to $urlquery, but by the time that the user is taken to sql.php, "goto" simply disappears. I'm not sure what I'm missing. Any clues? Thanks, Rouslan [1]: http://repo.or.cz/w/phpmyadmin/roccivic.git [2]: http://demo.phpmyadmin.net/gsoc-rouslan/

[Phpmyadmin-devel] Is PMA_STR_binarySearchInArr needed?
by Piotr Przybylski 08 Jun '11

08 Jun '11

Hi, For some time I was curious whether PMA_STR_binarySearchInArr is needed at all, and my test showed that there are faster (sometimes much faster) alternatives. Test for 100 000 iterations on PHP 5.3.4 (Windows, i5 2,53 GHz core): PMA_STR_binarySearchInArr: 2.6606s array_search: 1.8936s isset: 0.0102s array_key_exists: 0.0934s Isset and array_key_exists require flipped array, but array_search is a drop-in replacement that works faster, even though it does a linear search. Code used to perform this test is at [1]. [1] http://pastebin.com/cJmpmCPh -- Piotr Przybylski

[Phpmyadmin-devel] 3 patch suggestions for master
by Tyron Madlener 08 Jun '11

08 Jun '11

Since I always have a love for details, here's 3 small suggestions that maybe can be merged into the master branch. They are all pushed to my fork (http://repo.or.cz/w/phpmyadmin/tyronm.git): - Commit a0302c666c1bf9f9715364a6301238b474aedac1 Removes timepicker.js. It is already included with the jquery ui. The file was included only in tbl_change.php and tbl_select.php - Commit b161f43ec9089e0d2d5fb8a619056e6f9577a380 When reloading (flushing) privileges on the privileges tab you get a 5 second long success message. This commit omits the success message and removes the loading message as soon as the ajax request is done. This behavior seems more consistent with my patch in April that removes messages once the ajax request is completed. - Commit 99775c9bad552aac8b904996d673f1023821ab13 Removes the initials table on the privileges tab if there is 20 or less privileges to show. With 1-20 privileges you can easily see all host names and don't need any filtering by initials imo. I would even increase that limit to 30 or so.

[Phpmyadmin-devel] about strInsertTable
by Marc Delisle 07 Jun '11

07 Jun '11

Thilanka, I'm not sure where this message will appear exactly but I suggest replacing it with "Insert in table" with just the "I" of Insert in uppercase. By the way, in messages we are trying to avoid using uppercase for all words. -- Marc Delisle http://infomarc.info

[Phpmyadmin-devel] Merging server pages
by Tyron Madlener 06 Jun '11

06 Jun '11

I'd like to merge some of the server pages, so that we have a smaller menu and less links ending up in the 'More' tab. What I have done already is put the processes table into the status page as it fits very well into the server traffic (jquery-)tab. And secondly I would merge together Engines, Charsets, Replication and Variables into a (jquery-)tab-separated page named "Configuration" Since an average user rarely requires the information supplied on those pages I think it is a good idea to free up the space in the menu bar. Any objections on this? :)

[Phpmyadmin-devel] Hardcoded array sizes in sqlparser.data.php
by Piotr Przybylski 06 Jun '11

06 Jun '11

Hi, Is there any reason for hardcoding array sizes in sqlparser.data.php? count()'s complexity is O(1), it just reads item count from hash table which is used internally for storing arrays. -- Regards, Piotr Przybylski

[Phpmyadmin-devel] AJAXify phpMyAdmin Interface - GSOC 2011 - Add a new user in db-> privileges
by Thilanka Kaushalya 05 Jun '11

05 Jun '11

Hi Marc, I started working on improving the "*Add a new user in db-> privileges*" by providing a dialog such as in "*Add a new user in Server->privilege*" option. In that case I'm going to reuse the code in "(#fieldset_add_user).click" action in server_privileges.js file. The only modification I had to do is add the class="ajax" to link on db->privileges and now it pops up the dialog box. The next part is, after adding a new user we have to add that user to the list table in db->privileges and then sort it according to the alphabetical order of user names. In server->privileges, "*appendNewUser() in server_privileges.js" *method has used and it is sorting the rows be selecting the first character in the label and then according to that. It is okay because server->privileges table has same type of rows. But in "* db->privileges*" table it has used two type of rows where one shows columns related to "global" privileges and other is to database specific privileges corresponding to each user. So I cannot use the same "*appendNewUser() in server_privileges.js"* method to add and sort the table. I came up with some approaches to overcome this problem. 1. Change the table structure where do not use two rows but use same row and line break to get them down. In this case I'll be able to reuse the same method where I think more appropriate in this case. 2. Do a refresh to the "*db->privileges*" page so it reloads the table. 3. Keep the table as it is in current and develop a method to sort it. I'm confused with what method to use. So please can you clarify me on this problem. Thank you.
