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
