Okay, turns out this one is fairly easy to reproduce, using: - Ubuntu 16.04 - MariaDB Server (not tested on mysql, but I expect similar results) - php 7.0 (7.0.15) - phpMyAdmin
Configuration: MariaDB: max_allowed_packet = 128M php: post_max_size and upload_max_filesize raised to 128M Import the some SQL data, for instance: https://we.tl/vb37KISpUU. This will build you a MyISAM table with 4 columns, 3x varchar(1) and 1 longblob. The table will have one big blob in it, with 32Mbyte worth of 0x20 (space) Downloading the binary through phpMyAdmin on 7.0.15 will produce a file with a null-character inserted at (for my setup) 0xFFFFF6, the rest of the file is as expected. I'll try to get the testbuild working next... -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1668017 Title: Large mysql requests broken after security update, null character inserted close to 16MB boundary To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/php7.0/+bug/1668017/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
