Error saying "HTMLDOC is not installed" even though it is

[anonymous]

TrackWikiToPdfPlugin is installed via the easy_install method and is showing up and enabled in the admin section.

When I click to create a PDF/HTML/PS I get the error "HTMLDOC is not installed" although it is.

The system is FreeBSD 10.3 totally up to date and running the latest available versions of all programs (packages). Version of Trac in use is 1.0.9.

test:/ # htmldoc --version
1.8.28

test:/ # python
Python 2.7.11 (default, Jan 20 2016, 15:37:30)
[GCC 4.2.1 Compatible FreeBSD Clang 3.4.1 (tags/RELEASE_34/dot1-final 208032)] on freebsd10
Type "help", "copyright", "credits" or "license" for more information.
>>> import subprocess
>>> subprocess.Popen(('htmldoc', '--version'), stdout=subprocess.PIPE).communicate()[0]
'1.8.28\n'
>>>

Any help getting this working would be greatly appreciated!

Maybe we can log the exception and get more information: browser:/tracwikitopdfplugin/0.11/wikitopdf/wikitopdf.py@11507:180,182,183#L174​.

-    except OSError:
-        raise TracError("HTMLDOC is not installed.")
+    except OSError, e:
+        env.log.error("Error checking htmldoc version: %s", e)
+        raise TracError("HTMLDOC is not installed.")

Thanks for the answer but I now get the error

Trac detected an internal error:
NameError: global name 'self' is not defined

That patch was untested. I modified the patch in comment:1 after looking at the code again. Please try with the latest patch in comment:1.

Made the change and this is what I get in the error log:

Apr 29 15:21:53 noc Trac[wikitopdf] ERROR: Error checking htmldoc version: [Errno 2] No such file or directory
Apr 29 15:21:53 noc Trac[main] WARNING: [107.202.12.23] HTTPInternalError: 500 Trac Error (HTMLDOC is not installed.)

[Ryan J Ollos]

Maybe check where htmldoc is installed relative to the Trac egg. It might be that htmldoc is not on the path of the user under such the Trac process is running. Are you running TracStandalone or a Web server?

In 15520:

2.3.2: Use exception message when raising TracError

Remove tag_svn_revision attribute from setup.cfg. The
attribute isn't supported in setuptool >= 10.

Refs #12758.

Trac is running under apache as the user www which has access to run htmldoc

test:~ # su -m www
test:~ $ which htmldoc

[Ryan J Ollos]

After [15532], you could try setting the path to the HTMLDOC binary:

[wikitopdf]
htmldoc_path = /usr/local/bin/htmldoc

[anonymous]

Thanks. Got a little farther... I now get the error:

Trac Error
OSError: [Errno 2] No such file or directory

and essentially the same thing in the log file.

Here's the relevant section from trac.ini:

[wikitopdf]
base_dir = /home/trac
folder_name = EXAMPLE
htmldoc_path = /usr/local/bin/htmldoc
link = https://example.com/example/
tmp_dir = /tmp

In 15539:

Copy 0.11 branch to create 1.0 branch

Refs #6604, #12758.

[Ryan J Ollos]

There's a 1.0 branch now that adds additional changes described in #6604.

I'm not familiar with FreeBSD, but I can only imagine that this is somehow a permissions issue.

I've tried everything I can possibly think of but still get the error. Not sure what else to try but I'll keep at it. Thanks for the help getting it this far.

[Ryan J Ollos]

Replying to anonymous:

Trac is running under apache as the user www which has access to run htmldoc

Are you running with mod_wsgi or mod_python?

[Ryan J Ollos]

You could try running TracStandalone to see if it works with that configuration.

[anonymous]

Well, it suddenly decided to work. I've tried several things so not sure what it ended up being in the end but it does work now. Thanks for the help, I really appreciate it!

[Ryan J Ollos]

Good news!
