Hi Jun,
I did the test Ryan suggest:
# python
Python 2.7.12 (default, Nov 19 2016, 06:48:10)
[GCC 5.4.0 20160609] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> from trac.db.mysql_backend import has_mysqldb
>>> has_mysqldb
True
>>> from trac.db.mysql_backend import mysqldb_version
>>> mysqldb_version
'1.3.7'
>>> quit()
So, to me it looks like trac can detect the MySQLdb package in this newer
version. Running your test with debug output it prints like on your d-container:
07:36:16 Trac[loader] DEBUG: Skipping "trac.db.mysql = trac.db.mysql_backend
[mysql]": DistributionNotFound: The 'MySQL-python>=1.2.2' distribution was not found
and is required by the application
So somewhere in trac there is an additional check? I will look in the code
(although I am not a python dev) and try to find the cause of this failing
check. If you have any hints, it will be very helpful.
Thanks
Torge
Please try the following patch:
diff --git a/setup.py b/setup.py
index 5f6f2d7b1..1c93d9e41 100755
--- a/setup.py
+++ b/setup.py
@@ -97,7 +97,7 @@ setup(
],
extras_require = {
'babel': ['Babel>=0.9.5'],
- 'mysql': ['MySQL-python >= 1.2.2'],
+ 'mysql': ['mysqlclient'],
'postgresql': ['psycopg2 >= 2.0'],
'pygments': ['Pygments>=0.6'],
'rest': ['docutils>=0.3.9'],
All tests are passing for me. We might be able to add mysqlclient as a
supported database backend in Trac 1.2.3.
