MySQL backend fixes for Python 3.
With Python 2, text sent to and from MySQL is treated as bytes in
Python. The database may be recorded by MySQL as having some other
encoding (latin1 being the default in some MySQL versions - Roundup
does not set an encoding explicitly, unlike in back_postgresql), but
as long as MySQL's notion of the connection encoding agrees with its
notion of the database encoding, no conversions actually take place
and the bytes are stored and returned as-is.
With Python 3, text sent to and from MySQL is treated as Python
Unicode strings. When the database and connection encoding is latin1,
that means the bytes stored in the database under Python 2 are
interpreted as latin1 and converted from that to Unicode, producing
incorrect results for any non-ASCII characters; furthermore, if trying
to store new non-ASCII data in the database under Python 3, any
non-latin1 characters produce errors.
This patch arranges for both the connection and database character
sets to be UTF-8 when using Python 3, and documents a need to export
and import the database when moving from Python 2 to Python 3 with
this backend.

======================================================= Roundup: an Issue-Tracking System for Knowledge Workers ======================================================= INSTANT GRATIFICATION ===================== The impatient may try Roundup immediately by running demo.py from the source directory:: python demo.py This will create new tracker home in "demo" subdirectory and start server. To reset demo instance:: python demo.py nuke Tracker Home ============= "Tracker Home" is main concept when starting with Roundup. It is directory where all your tracker data is stored. This directory is created every time when new tracker is initialized and includes tracker configuration, database, template, schema and extensions. Installation ============ Please see "doc/installation.txt" Upgrading ========= Please see "doc/upgrading.txt" Usage and Other Information =========================== Start with the index.txt file in the "doc" directory. These documentation files are written in reStructedText, which can be converted into HTML format. If you have Sphinx installed, you can do this by running:: python setup.py build_doc Resulting HTML files will be in "share/doc/roundup/html" directory. For Developers ============== To get started on development work, read the developers.txt file in the "doc" directory. License ======= See COPYING.txt
