Flat-file PHP issue tracker

Question

I need a self-hosted issue tracker that

• is written in PHP,
• doesn’t require a database, and
• is free/libre/open source.

Required features

• An issue can have a category ("bug", "feature request", "support") and a status ("closed", "open", "on hold").

• An issue can be commented.

• Issues and comments can have image attachments.

• Email notifications for new issues and new comments.

• The list of issues can be filtered by category and status.

Nice-to-have features

• When referencing issues/comments internally, the links should be relative (or there should be a config option to change the hostname) so that switching domains is hassle-free.

Answer 1

You should have a look at Traq. It runs with the file based "database" Sqlite (look at the travis configurations).

It has a nice user interface and all the features you are looking for.
