My *first attempt to create a wheel* is as follows:
1) download zip file via the link at the bottom of page
https://trac-hacks.org/browser/graphvizplugin
2) unzip graphvizplugin-17761.zip
3) cd graphviz/trunk
4) python setup.py bdist_wheel
# dist/TracGraphviz-1.3.0.1.dev0-py2-none-any.whl

So... I now have a *.whl file that I will attempt to install... I will let
you know if it works...

My log file has the following message (I've retyped it):
" Loading plugin "graphviz" from /usr/local/lib/python2.7/dist-packages"
"Skipping "graphviz = graphviz.graphviz": ImportError: No module named
graphviz

So... something has gone wrong. Will need to revisit... maybe I should try
creating an egg instead and use that... hhhmm... thinking...

DEPRECATION: Python 2.7 reached the end of its life on January 1st, 2020.
Please upgrade your Python as Python 2.7 is no longer maintained. pip 21.0
will drop support for Python 2.7 in January 2021. More details about Python
2 support in pip, can be found at
https://pip.pypa.io/en/latest/development/release-process/#python-2-support
ERROR: Could not find a version that satisfies the requirement easy_install
(from versions: none)
ERROR: No matching distribution found for easy_install

Seems there is no longer an "easy_install" program to install eggs? Sigh...
entering dependency hell...

Has anyone been able to get GraphvizPlugin to intall on Trac 1.4.1? If so,
help is appreciated... I seem to be reaching my limit on what to do next...

Kindly,
Aikido Guy

Seems that I do NOT need to download easy_install... it was already
available... "python -m easy_install *.egg".

So... I built the egg file for GraphvizPlugin and copied that to my server
and installed it via "python -m easy_install
TracGraphviz-1.3.0.1.dev0-py2.7.egg".

I have now moved 1 step forward and get the following error message in my
Trac project log: "Skipping "graphviz = graphviz.graphviz" : ImportError:
No module named genshi.core.

So... I will do a pip download of the Genshi wheel and install it and see
if this gets me 1 step closer...

Kindly,
Aikido Guy

There is no Genshi wheel. What I downloaded was Genshi-0.7.3.tar.gz. I then
gunzipped it and untarred it. Then I "python setup.py bdist_egg".

This gave me Genshi-0.7.3-py2.7-linux-x86_64.egg. And I took that egg over
to my server. and installed it "python -m easy_install
Genshi-0.7.3-py2.7-linux-x86_64.egg"

I made the new directory readable and executable by "other". However, I get
the same error as before: "Skipping "graphviz = graphviz.graphviz" :
ImportError: No module named genshi.core."

Any thoughts?

Kindly,
Aikido Guy

I haven't read the whole thread yet, but there is a Genshi Wheel on PyPI:
https://pypi.org/project/Genshi/0.7.3/#files

You so install to site-packages using:
$ pip install genshi

I don't know if Graphviz will work with Trac 1.4 because it relies on
Genshi stream filters and we've migrated to Jinja2. I will take a look at
the plugin in a few hours.

Thanks! I took a look at the listing and it shows 2 files:
- "Genshi-0.7.3-py3-none-any.whl" and
- "Genshi-0.7.3.tar.gz"

The first looks like it is for python 3 and the second is what I downloaded
from the command line... which I then used to try to build an egg for
python 2.7... I know it is deprecated, but it is what I have at the moment
due to mod_python being for python 2.7 (I believe)

You so install to site-packages using:

Thank you for this command... unfortunately I can't do that from my server
because it is air gapped at the moment...
- as a side note... on ubuntu... it will install to
"/usr/local/lib/python2.7/dist-packages/"

I don't know if Graphviz will work with Trac 1.4 because it relies on

I would very much appreciate it if Graphviz could be used with Trac 1.4...
at least until mod_python is able to be upgraded to python 3. Does anyone
know if that is happening? ;)

Very kindly,
Aikido Guy

You are right about that. If I install in Python 2.7 the wheel gets built
from the sdist:

Trac doesn't support Python 3 yet, but we are getting close.
https://trac.edgewall.org/ticket/11988

Change log (http://modpython.org/) says:

Oct-25-2013 The latest pre-release version now supports Python 3! Please
take a minute to help us test it
<https://github.com/grisha/mod_python/issues/9>.
Nov-13-2013 3.5.0 is released.

But I don't know if it works with a recent Python 3 release. You could
switch to mod_wsgi.

After confirming that Genshi is installed (the version should be shown on
the /about page), grab the latest source. I pushed a fix just now.

$ python setup.py bdist_wheel
$ ls dist/
TracGraphviz-1.4.0.0-py2-none-any.whl
$ pip install dist/TracGraphviz-1.4.0.0-py2-none-any.whl

Confirmed it displays a simple diagram (example copied from wiki page) with
Trac 1.4.2dev.

I successfully created and tested TracGraphviz-1.4.0.0-py2-none-any.whl

However, I did encounter one hiccup that stopped it from working out of the
box.

I needed to create TracEnv/files directory and TracEnv/files/gvcache
directory (they both did not exist).
- once these were both created with the correct ownership then I was able
to display both a simple graphviz plot (black and white) AND a plot in
colour. All good! Thanks!

Here is some of the log showing the error... can't type it all here... if
you really need it then I can take a photo and send it to you...
ERROR: Jinja2 OSError error while rendering XML/HTML template
Traceback
trac/web/chrome.py line 1704 in _iterable_jinja_content
for chunk in stream:
...
...
graphviz/graphviz.py line 231 in get_macros
self._load_config()
graphviz/graphviz.py line 491 in _load_config
os.mkdir(self.cache_dir)
OSError: [Errno 2] No such file or directory '..../files/gvcache'

Perhaps I need to look at the graphviz options.... however, it would be
nice it graphviz created this directory if it is needed?

Thank you for your very kind help getting my original quation resolved for
me!

Warmest regards,
Aikido Guy

Graphviz will create $env/files/gvcache if $env/files exists. $env/files
will be created the first time you upload an attachment, or if you migrate
an old environment with attachments to Trac 1.0+.

Graphviz should create the parent directory $env/files if it doesn't exist.

Are you using a new environment for testing and haven't uploaded an
attachment yet, or do your production environments not use attachments?

I'm using a new environment (with no uploaded attachments) to ensure
everything is working before I start migrating my production environments.

Likely I will create the files directory for all environments if it does
not already exist in order to ensure none of my production environments see
this issue...

Thanks again for all of your GREAT help! I may request some more help in
the future for a different plugin, but I think this will be good for now ;)

Kindly,
Aikido Guy

Upon closer inspection... my production environments have "$env/gvcache"
directories and not "$env/files/gvcache".

Will the upgrade process properly handle this? i.e. move gvcache/ inside
files/?

Trac upgrade will not move gvcache. The directory living directly under
$env does sound familiar from years ago when I last used the plugin. I
would guess that it's been moved and you'll have to relocate the directory
in your own upgrade script.

Thanks for letting me know about this little gotcha ;) I'll take care of
it...

I downloaded the python 2.7 wheel from PyPI and can confirm that it is
active as TracGraphviz 1.4.0.1 in my Trac plugins admin pane.

I also deleted the $env/files directory and then reloaded the wiki page
with my 2 test graphs
- I can confirm that the $env/files directory and the $env/files/gvcache
directory were both successfully created

Thank you... kindly,
Aikido Guy
