fcgi not working - trac 1.5.4 + lighttpd + python 3.10

[anonymous]

fcgi doesn't work out-of-the-box in trac 1.5.4 + lighttpd + python 3.10 due to a dud import line.

Here's a patch that fixes it.

Weird. I don't think the patch fixes it.

from ._fcgi import WSGIServer is a relative import from trac/web/fcgi_frontend.py and source:/trunk/trac/web/_fcgi.py​ is imported.

After the patch, from _fcgi import WSGIServer is an absolute import and _fcgi.py in sys.path is required.

$ python3.10 -c 'import _fcgi'
Traceback (most recent call last):
  File "<string>", line 1, in <module>
ModuleNotFoundError: No module named '_fcgi'

That's an InstallationIssue. Works for me (verified with lighttpd 1.4.55, Trac 1.5.4 and Python 3.10).
