phpMyAdmin work during twenty fifth, twenty sixth and twenty eighth weeks

This is my final blog post reporting about the work I have carried out under the phpMyAdmn developer contract. However, I will continue to contribute to phpMyAdmin in a voluntary basis.

During the period, my focus was solely on bus fixes. This was mostly due to the continuous stream of bugs we were receiving and most of the bugs were related to the newly released 4.6 version. 

Following are the bugs fixes during the period.

issue #12092 Rename exported databases/tables doesn't seem to work

issue #12099 Undefined index: controllink

issue #12094 PHP Fatal error: Call to undefined function __()

issue #12116 Fulltext indexes are not copied when using copy database function

issue #12125 Cannot highlight a column if I scroll down from the top of the table

issue #12132 Can not open table with JSON field

issue #12143 Cannot login with certain password

Additionally, I attended to the following bugs.

issue #12088 Improper comment creation and escaping with Percona 5.7 (` instead of ', extra "AS")

issue #12091 Import file does not working when data have \' (4.6.0rc2)

phpMyAdmin work during nineteenth and twentieth weeks

During the nineteenth and twentieth weeks, I was away from work between 2nd Feb to 10th Feb. However, during the rest of the days, I engaged in both code refactoring and bus fixes. Early on the fortnight, I refactored the server binary logs page to use the MVC architecture. This included introducing a controller class, using templating and updating unit tests.

Bugs attended
issue #11922 Browse fails with users who have only column privileges for some columns
issue #11434 Class 'SqlParser\Lexer' not found (OS X)

phpMyAdmin work during seventeenth and eighteenth weeks

My work during these two weeks concentrated pretty much on the security vulnerabilities that were reported. We received two lengthy reports on a number of security vulnerabilities which included cross-site scripting, full path disclosure, weaknesses in token generation and comparison etc. Altogether these vulnerabilities resulted in 9 PMASAs taking into the different combinations of phpMyAdmin versions they affected.

I contributed by fixing some vulnerabilities, testing security patches, porting some fixes done by others developers to older branches, preparing PMASAs and coordinating with the reporter, CVE team and phpMyAdmin security team.

The latter part of the fortnight was spent on fixing two regressions introduced by the security releases. 

issue #11891 Error with PMA 4.0.10.13 with PHP 5.2

issue #11892 Error with PMA 4.4.15.3

Moreover, following bug was fixing during the two weeks.

issue #11881 Full processlist lost on refresh

phpMyAdmin work on sixteenth week

I was continuing on my year-end break on fifteenth week and did not work during the week, except for 2 hours on 4th January. So this report includes work carried out during the sixteenth week.

During the week, I concentrated solely on bug fixes since there were a sizable number of bugs being reported. Most of the bugs fixed were regressions. For example, #11771 and #11846 were only present in latest git version and was due to refactoring and JS library updates respectively.

The complete list of bugs fixed and investigated are as follows,

Bugs Fixed

issue #11771 Transformation column path problem

issue #11772 Table pagination does nothing when session expired

issue #11810 'Add to central columns' in tbl_structure.php (per column button) nothing happens

issue #11814 SQL comment and variable stripped from bookmark on save

issue #11840 Index comments not working properly

issue #11846 Grid editing window is disabled the second time

issue #11854 Undefined property: stdClass::$releases at version check when disabled in config

Bugs Investigated

issue #11712 "Browse Foreign Values" Search broken across databases in 4.5.2

issue #11713 Not receiving notifications for updates

issue #11842 Fractional timestamp not supported

issue #11843 Fractional timestamp causes corrupted SQL export

phpMyAdmin work during twelfth, thirteenth and forteenth weeks

With my personal engagements and summer break, I worked only for 13 hours during the three weeks. During the period, I was mostly engaged with refactoring work and improving the unit testing. 

Continuing from the last couple of weeks, I refactored the server plugins page to use the MVC architecture. Code segments that were previously in a library file were moved to a controller class and instance variables were introduced as required. The view was changed to use templating and unit tests were updated to match the new classes.

I also went on to improve the unit testing by introducing a parent class to all the unit tests. With the new class, configuration values are reset to their default values for each test class. The idea was to make unit tests independent from changes made to configuration values in other unit tests. Meanwhile, unnecessary configuration values assignments in tests were removed.

Additionally, following bugs were investigated during the period.

Bugs Investigated
issue #11743 Display routine-specific privileges under Database > Privileges
issue #11751 Bug when export template is selected

phpMyAdmin work during tenth and eleventh weeks

During the two weeks most I attended a mix of bug fixing, implementing new features, refactoring and unit test improvements.

I did not realize that some of the unit tests were not running as part of the test suite unit Michal pointed out and included them. However, this caused quite some test failures as most of the recently added and updated tests had not been running. These were fixed at the very beginning of the period.

Unit Testing

Fix unit test failures related to refactoring

Quite a number of bugs were fixed during the two weeks and some more were investigated. Following are the list of bug fixes attended.

Bug Fixes

issue #11701 Show create procedure SQL

issue #11706 Database export template not saving compression option

issue #11710 Unable to add/remove `on update CURRENT_TIMESTAMP` option while editing a timestamp field

issue #11724 Temporary fix for live data edit of big sets is not working

issue #11728 CSV import skip row count after

issue #11732 Exporting feature does not work with union table

issue #11722 Excel import improper handling of dates/times

issue #11732 "Browse Foreign Values" Search broken across databases in 4.5.2

issue #11734 No result shown, if writing statement, comment, single select

Inbility to reorder parameters of routines had bothered me in the past. So, as requested in issue #11701, I implemented the ability to do this.

Feature Enhancements

issue #11701 Allow changing parameter order of routines

Moreover, continueing the refactoring effert from last fortnight I went on to refactor server engines page. This involed introducing a controller class and using templating to adhere to MVC pattern. Unit tests were also updated to match the new classes.

Refactoring

Refactor server engines page to use MVC pattern 

phpMyAdmin work during eighth and ninth weeks

Last two weeks were dedicated completely to code refactoring where I converted a couple of server level page to MVC architecture. This is a continuation of what started during the last GSoC where we started to take up MVC architecture.

I started with server_variables.php page and created a new controller named ServerVariablesController to handle all interactions from the page. Refactoring included moving the HTML generation to 'View' (using templating) and organizing previous functions into methods and introducing instance variables where appropriate. 

Server databases page was also refactored in a similar manner. Additionally, the functionalities of display_create_database.lib.php, db_create.php and build_html_for_db.lib.php were integrated into the new controller. Moreover, some functionalities that supported both ajax and non-ajax behavior (that used to facilitate scenarios with JavaScript disabled) was simplified. Towards the end of the period, server charsets page was refactored in a similar manner.

Code refactoring
Refactor server variables page to use MVC architecture
Refactor server databases page to use MVC architecture
Simplify database dropping
Merge the functionalities of display_create_database.lib.php, db_create.php and build_html_for_db.lib.php into ServerDatabasesController
Refactor server charsets page to use MVC architecture
Organize controllers into a better package hierarchy

I also engaged in fixing coding style violations, both introduced by refactoring as well as the ones that already existed. Further, I updated the test suite to account for newly introduced controller classes and now removed functions.

Update unit tests for new controller classes

phpMyAdmin work during sixth and seventh weeks

During the two week I attended to a combination of bugs, features/improvements, code refactoring as well as code quality improvements. However, most of the time was spent on bugs as there were number of bugs being reported. Following are the bugs fixed and investigated during the two weeks.

Bugs fixed

issue #11476 Errors instead of git info when PHP has no gzip support

issue #11630 Warning: mysqli_fetch_array() expects parameter 1 to be mysqli_result, boolean given

issue #11651 Issue while creating tables

issue #11659 Totally turn off autocomplete and sql syntax check

Among the new features implemented, issue #11641, which requested to disable one of the relational features, was discussed during the team meeting and it was suggested to use a special value for the same configuration directive to disable the feature. This was implemented targeting future 4.6 release. Additionally, as part of minimizing the upload footprint, GIS features were adjusted to function without bulky OpenLayers library. Moreover, profiling chart now uses the generic charting mechanism which facilitate moving to a new charting library with less hassle.

New features/Improvements

issue #11641 Ability to disable the navigationhiding Feature

issue #11654 Use a slider for Internal relations

Make OpenLayers library optional for GIS visualization

Link license.php

Use generic charting mechanism for profiling chart as well

Additionally, following refactoring and code quality improvement work was carried out during the period.

phpMyAdmin work during third, fourth and fifth weeks

I did not engage in phpMyAdmin development work during the fourth week while I was less active during the third week due to personal engagements. So, here is a combined blog post for third, fourth and fifth weeks.

During the period I worked on fixing the bugs reported by users as well as those reported by the automated error reporting mechanism. I cleaned up automatically reported errors by exporting them to GitHub tracker, linking them where necessary and by fixing them. Following are the bugs fixed and investigated during the period. 

Bugs Fixed
#11551 Fatal error when switched to master from QA_4_5
#11594 'only_db' config option bug when db names contain underscore and are grouped

phpMyAdmin work during first and second weeks

I started my second year as a contract developer for phpMyAdmin project on 1st of October 2015. However, this year I have limited my hours, working only on part time basis. I hope to work for 20 hours a week. Since there were only two days on the first week I am combining the work done on the first week with that of the second. 

The first two weeks was totally focused on bug fixes since there was a constant steam of bugs from the newly released 4.5 version. Most of the bugs were related to the rewritten parser and I got good insight on the new parser while trying to fix some of these bugs. Following are the bugs fixed.

Bug fixes
issue #11521 Notice of undefined variable when performing SHOW CREATE
issue #11522 Strange behavior on table rename
issue #11526 Foreign key to other database's tables fails
issue #11539 Rename table does not result in refresh in left panel
issue #11544 Notices about undefined indexes on structure pages of information_schema tables
issue #11546 "Visualize GIS data" seems to be broken
issue #11548 Confirm box on "Reset slave" option
Fix notices while changing from HASH type to RANGE type
UI does not support inserting multiple values for JSON functions
Tracking does not make sense for information_schema
Fix cookies clearing on version change

Moreover, following bugs were investigated during the period.

Bugs investigated
issue #11515 Multi source replication is not recognized
issue #11538 Copy multiple tables to database
issue #11536 Format of exports looses SQL on 2nd export
issue #11547 "distinct" removed from query while query result export to excel

I plan to spend more time on refactoring in the coming weeks.

Leave days - 7th Oct

phpMyAdmin work during fiftieth and fifty first weeks

During these two weeks I worked relatively lesser number of hours and had to take a couple of days off. So, I am combining the work done during the two weeks to a single blog post.

During the two weeks I concentrated mostly on feature enhancements. Two major features were implemented during the period. First of them is the ability to specify the routine level privileges and I noticed that this feature is missing when I went though the MySQL GRANT syntax. Even though this sounded easier when I started working on it, it took two full days to complete the feature. This was mostly due to the code quality of the related code segments. So, I'd put server_privileges.php file as one of the key places where refactoring can help.

The second major feature is the UI to define partition definitions. Existing create table UI has only a text area to define the partition definition. Someone who is not familiar with partition syntax would not be able to do this with the old UI. The new UI allows specifying partitioning parameters and parameters for each partitions. Additionally, I worked on making the metro theme compatible with the 4.5 version. I had accumulated commits for this for sometime. During the two week I did the final touches and the pull request was merged.

Feature enhancements
Issue #11479 Allow setting routine wise privileges
Issue #11490 UI for defining partitioning in create table window
Pull #6 Metro theme for future version 4.5
Add server plugins page
Minor UI improvements to the User accounts page

Additionally, following bugs were fixed during the two weeks.

Bugs fixed
Issue #11464 phpMyAdmin suggests upgrading to newer version not usable on that system
Issue #11475 Warnings linked to Drizzle
Issue #11487 Warning when entering Query
Issue #11491 Propose table structure broken
Do not suggest upgrading when there is no compatible versions

Leave days : 17th, 23rd

phpMyAdmin work during forty eighth and forty ninth weeks

I am combining two weeks of work into this blog post. I took 3 days off work (on 1st, 7th and 11th of September) and this is mostly why I am combining work of two weeks.

Following are the bugs fixed and investigated during the period.

Bugs fixed
Issue #11445 MySQL 5.7 and Status page for an unprivileged user
Issue #11446 MySQL 5.7 and Variables page for an unprivileged user
Issue #11450 Validation fails when using functions
Issue #11451 Designer-Bug in move.js on multiple server configuration
Issue #11454 Find and replace is broken
Issue #11457 414 Request-URI Too Large
Issue #11461 Foreign key constraints for InnoDB tables with upper-case letters disabled

Bugs investigated
Issue #11453 Paste command is gone in 4.4
Issue #11464 phpMyAdmin suggests upgrading to newer version not usable on that system
Issue #11470 Impossible to cancel "Drop files here" overlay

Issue #11445 and #11446 was due to permission changes introduced in MySQL 5.7 which prevented unprivileged users from issuing SHOW commands. Issue #11454 was a regression in upcoming 4.5 version this was fixed for the release candidate. Issue #11461 was tricky to fix, however only affected the apple users.

With regard to feature enhancements, the major change was the removal of Drizzle support. Development of Drizzle has been abandoned for years and hence support for Drizzle will be removed from version 4.6.  Most of the development work of issue #6297 was carried out during earlier weeks. However, it was during this period the pull request got merged.

Feature enhancements
Issue #6297 Use GET only for read only operations
Issue #11456 Disabled storage engines
Remove Drizzle support from master branch
Mark default storage engine

A security vulnerability was reported after some time during the two weeks. The vulnerability was in code related to reCaptcha test which is an additional opt-in security feature provided in phpMyAdmin.

Security fixes
Fix reCaptcha bypass

phpMyAdmin work during forty sixth and forty seventh weeks

During this period I moved from Colombo to Melbourne, Australia. So, I had to take couple of days off on both weeks for preparation work as well as settling down in Australia. Hence, I am combining the work done during these two weeks to a single blog post.

The bugs fixed during the time includes bugs from both stable version and the upcoming 4.5 version. 

Bugs fixed
#11404 "Switch to copied table" doesn't work
#11408 Export breaks when field name is 0
#11410 SPATIAL index option is not clickable
#11414 Unclear export options / organization / hierarchy

Fix - Do not export `sys` database when exporting server
Add missing 'sql_create_database' configuration to setup and user preferences

Additionally, following bugs were investigated.

Bugs investigated
#11433 '%' does not work as it is with sprintf
#11434 Class 'SqlParser\Lexer' not found

With regards to the feature enhancements, there were no major features implemented during the period. However, a number of smaller enhancements were carried out. I also went on to do some language improvements where a number of sentences that used title case were converted to sentence case to be compliant with phpMyAdmin language guide. Moreover, I started working on supporting JSON data type introduced in MySQL 5.7.8. However, this had to be postponed due to bugs in PHP with respect to JSON data type.

Feature enhancements
Improvements to partition details on table structure page
Spatial indexes with multiple columns are not allowed
Organize SQL export options
Make the SQL exports compatible for side by side comparison with old exports
Allow editing unless it's a static variable. Allow editing new dynamic variables added in MariaDB and newer versions of MySQL
Minor UI improvements in zoom search page
Language improvements - Use sentence case as per phpMyAdmin language guide

Feature requests investigated
#11438 Support JSON data type

phpMyAdmin work during forty fourth and forty fifth weeks

I took leave on first three days off on forty fourth week to visit Anuradhpura and here I am combining the work done on the rest of the two days with the work done on the forty fifth week in to a single blog post.

During the two weeks I continued to QA the development version to identify any bugs arising from the ongoing developments. So, most of the bugs were fixed in the master branch. Additionally I fixed two incompatibilities with PHP7 in the stable version of phpMyAdmin. Both these incompatibilities were in third party libraries we use and these libraries were upgraded and tested.

Bugs fixed

#11345 Token mismatch error

#11349 Table list doesn't expand when current table on different page

#11364 JS error when trying to navigate to db structure page after db creation failed

#11382 Selecting values for set field throws JS error

#11389 ReCaptcha produce deprecated messages under PHP 7

#11387 phpseclib < 2.0 produces deprecated messages on PHP 7

Fix - Counting real number of rows always return zero

Fix - Index list not updated upon dropping a column

Bugs investigated

#11384 Query formatting adds space between ! and =

The highlight in terms of feature enhancements is the improved partition support. Now you can view all the details related to table partitions and sub partitions in the table structure page. Moreover, all the partition operations can be performed from there. 

Additionally, I improved the cache invalidation on version upgrade. With the new page loading introduced in version 4.0, phpMyAdmin cached the JS files and fired the relevant event on loading a page. Now these cached files are invalidate upon version upgrade.

Feature enhancements

Improved partition support

Clear internal cache at script handler upon version upgrade

Minor UI improvements to the db operations page

Do not attach index table unnecessarily

Refactor db_designer.php

Code quality improvements

Create separate controllers from table and database structure pages

Organize templates into a meaningful structure

Fix coding style issues reported by PHPCS

phpMyAdmin work during forty third week

During the week I mostly focused on fixing bugs. I attended to a mix of bugs that were prevalent in current stable version as well as those arose due to ongoing development targeting the next major release. 

Among the older bugs, I went on to investigate a couple of bugs related to replication features. Since I did not have a replication setup I first created such as investigated the bugs that had been reported. Bug #10307 which reported how cross database replication was broken due to the use of fully qualified table names was fixed. Other replication related bugs, which were also quite old, were mostly out of date.

Bugs that were fixed and investigated during the week are

Bugs fixed
#10307 Replication broken when using cross-database master/slave config and phpMyAdmin
#11322 Missing null checkbox when grid editing a null cell
#11324 JS error while opening a new page in Desginer
#11326 Exported schema includes all the tables of the database
#11328 Exporting table generates AUTO_INCREMENT=; for new tables
#11334 Table creation time, last update and last check column are empty
#11336 Exporting a table exports database level events
Fix various broken features due to refactoring in database structure page
Fix retrieve default storage engine correctly

Bugs investigated
#10435 Revoking non-existent Grant Option breaks MySQL 5.6 Replication
#10622 "Loading" doesn't disappear when stopping replication slave
#11325 Exporting database schema to PDF is broken
#11327 Default value for BIT column exported as b

When analyzing the JS errors reported in error reporting server, it was evident that quite a lot of them were due to caching issues on upgrading to a new phpMyAdmin version. This was addressed during the week and hopefully these issues will no longer occur.

Enhancements
Avoid caching JS and CSS files across phpMyAdmin versions
Upgrade TCPDF to version 6.2.9
UI improvements to replication and binary log pages
Improvements to the feature allowing to export databases and tables into separate files

phpMyAdmin work during forty second week

During this week I attended to a mix of bug fixes and feature enhancements.

I installed upcoming MySQL 5.7 and paid attention to areas in phpMyAdmin that needs to be updated to work with 5.7. First of all I noticed that I am unable to create phpMyAdmin configuration storage table since TIMESTAMP columns in them lacked a default value and this is not allowed in MySQL 5.7. Moreover I attended to a couple of UI bugs I happen to notice while I was working. Following are the bugs that were fixed.

Bugs fixed
#1808 "Improve table structure" generates invalid SQL
#1817 Creating configuration storage tables fail in MySQL 5.7
UI fixes in error reporting feature
Fix legend for table SQL page
Fix gutter style for normal and dark console themes

On the feature enhancement front, the major work was to improve the rtl language support. There were quite a number of instances that were broken even in the current stable version. Since Arabic is not shipped currently due to lack of translation, these were fixed in master branch. While some of these were style changes, others involved changing the DOM structure. Additionally, I attended to some UI improvements as well as improvements targeting MySQL 5.7

Feature enhancements
UI improvements in the 'Variables' and 'SQL' pages
Allow linking MySQL 5.7 document links
Terminology improvements in the 'User accounts' and 'Privileges' pages
Document SQL parameter binding feature
Improve support for rtl languages
Update ChangeLog links
Mark MySQL 5.7 'sys' schema as a system schema

Since GSoC work is ongoing, we could observer an increase in coding style violations reported by PHPCS. During the week, I attended to these violations as well.

Code quality improvements
Fix PHP coding style violations reported by PHPCS

P.S. This was a four day week with me taking leave on Thursday.

phpMyAdmin work during the forty first week

During this week I attended to bug fixes, new features as well as general coding improvements. 

The highlight of the week in terms bug fixes was the ability to use error reporting server. It was not usable for a long time and now that the situation has improved to Smitha, I attended to a number of bugs reported there. I noticed that a large number of bugs were due to caching issue while upgrading. This affected relational features on PHP front while a number of JS issues reported were also due to this. I also engaged in reporting issues and sending pull requests to improve the error reporting server. Bugs fixed and attended during the week are

Bugs fixed
#4979 Problem when import *.ods file
#4980 Cannot read property 'status' of null
#4981 Uncaught TypeError: Cannot read property 'attr' of null
#4984 Undefined <feature>work upon upgrade to new version
#4985 Column headers move when scrolling

Bugs investigated
#4983 Theme configurations not defined
#4986 First stack trace item missing in PHP error reports

The highlight in terms of new feature is the support for virtual columns. Support for virtual columns was initially requested for MariaDB. However my earlier attempt to implement the feature was abandoned due to lack of parser support. Virtual columns are featured in upcoming MySQL 5.7 as well and since the column expression can be extracted from information_schema in MySQL I could add support for MySQL virtual columns without parser update. After discussing this on developer mailing list GSoC student who is working on the parser rewrite added support for virtual columns to the new parser and with this I went on to extend the feature for MariaDB as well.

Feature requests implemented
#1517 Support for MariaDB virtual/persistent columns
Support MySQL 5.7.5 virtual columns

Feature requests investigated
#1658 Better Performance

To the latter part of the week I worked on improving coding style which had deteriorated a bit during the last couple of months.

Coding improvements
Centralize querying for SHOW CREATE TABLE statements
Documentation improvements on upgrading
Fix PHP coding style violations reported by PHPCS

Forty first week of my work was a four day week with me taking 16th of July as day off.

phpMyAdmn work during the fortieth week

The fortieth week of work was mostly spent on fixing the bugs in the upcoming 4.5 version. 

While implementing the export templates I noticed that lock_table directive is not repopulated similar to other directive when back button is click and this was fixed. Further, quite a lot of the links to new system variables in phpMyAdmin's Variables page  was missing, and these were also added. Bug #4854 was fixed allowing users to use multiple servers in parallel. Earlier this was not possible and a series of fixes such as introducing IV per server finally led to this fix.

Here is the list of bugs fixed and investigated.

#4854 "Error: Token mismatch" when using multiple servers in parallel
#4973 Show a warning when a user account allowing any user from localhost to connect (partial fix)
#4976 Timepicker CSS issues in Original theme

Bugs investigated

Among feature improvements, the most notable one is the use of native tabs in server plugin page in place of the jQuery tabs. Additionally, the process list was updated to show additional columns for MariaDB and as discussed during the last team meeting names of some of the pmadb directives were changed.

#1685 mariadb processlist
Underscores are preferred to separate words in configuration storage table names/directives
Use phpmyadmin's secondary tabs instead of jQuery tabs in server plugins page
Set indeterminate for export checkboxes when either data or structure is not selected
