# 0 bytes PDFs on 0.11

Reported by: Owned by: romel diorgenes normal TracWikiToPdfPlugin critical 0.11

### Description

I installed WikiToPdf plugin in Trac 0.11 and when I try to get the PDF via WikiToPdf link in the bottom or via admin I got a 0 bytes PDF file.

This does not happen with Trac 0.10

### comment:1 follow-up: ↓ 3 Changed 8 years ago by dferg

I agree. On 0.11rc2 I get a 0 byte pdf from the WikiToPdf link. However, if I try to use the admin interface, I get an error:

"You're using a plugin which requires the Clearsilver template engine and Clearsilver is not installed. Either disable that plugin or install Clearsilver."

I have not tried it on 0.10.

Hi Romel

Do you install htmldoc? What is your system? If Linux, what is your distribution?

Your configuration's file (trac.ini) is correct?

My installation have:

• Genshi-0.5-py2.4-linux-i686.egg
• TracWikiToPdfPlugin-2.0-py2.4.egg
• Trac0.11

It is need install Genshi (Clearsilver).

Windows 2003 Server.

You tested both forms of generating PDF? What happened them the error(Combining wiki pages or Single page)?

I'm only trying the TracWikiToPDF at the bottom of a page, so I assume that is the single page. I can't run the admin plugin because I don't have clearsilver installed (I couldn't find a windows binary for Python 2.5).

I added two log lines:

os.system('htmldoc %s %s -f %s' % (args_string, hfilename, pfilename)) self.env.log.debug('WikiToPdf => Htmldoc done hfilename: %s' % hfilename) self.env.log.debug('WikiToPdf => Htmldoc done pfilename: %s' % pfilename)

and now it seems to be working... Hmmm.

Hi everyone!

This problem occurs when you try to generate the PDF book? If yes, verify the Wiki pages contains the titles format. Ex:

Code wiki page

= Title =
description

== Sub-Title ==
description


The error appear because not find the title formated the wiki pages.

The plugin TracWikiToPdfPlugin not necessary use clearsilver, but optional if some plugins require it.

Do you usually the new version plugin (2.2.1)? Which format are you using (combining wiki pages or single page)?

I just tried including the new version built from source(TracWikiToPdfPlugin-2.2.1-py2.5.egg) and still the same problem as the other posters:

For combining wiki pages in the admin area I get "You're using a plugin which requires the Clearsilver template engine and Clearsilver is not installed. Either disable that plugin or install Clearsilver."

For trying to export a single page to PDF I get a 0 byte PDF file.

I tried using the pre-built egg in the directory (TracWikiToPdfPlugin-2.2.1-py2.4.egg) just for kicks and it wouldn't run.

Operating system is CentOS 5 Linux.

If yes, please return its result here.

You need install the package python-clearsilver. Because the plugin TracWikiToPdf yet need package template.

The Trac 0.11 use new template package. I will re-write my code for use Genshi template, but I need before learn to use the template package.

This is proving to be annoying. I installed python-clearsilver with no luck. went back and have now done a full reinstall of both clearsilver and python clearsilver. Am currently rebuilding and installing htmldoc, and will then rebuild the egg from source. hopefully it will work after that.

I have installed: Trac-0.11.3 Genshi-0.5.1 trac-wikitopdf-2.2.2 htmldoc 1.8.27 clearsilver-0.10.5

### comment:31 Changed 7 years ago by MartinBeyer

Hi, we installed it on Windows 2003 as a service. The details are probably irrelevant: we integrated trac with Subversion, with an Apache httpd interface, using the Collabnet Subversion Distribution.

When the service is started under the system account, WikiToPdf generates empty PDF files. The temporary HTML file is generated correctly (I commented out the unlink command to see it). HTMLDOC is called correctly or at least the logfile says so. The PDF file is generated, but it is empty.

When HTMLDOC is called manually it correctly generates the PDF.

Starting the service with an admin account instead of the Windows system account solved the problem at our installation, both for using WikiToPdf on single pages and via the Admin panel. Regards, Martin.

### comment:32 Changed 7 years ago by anonymous

Over here, 0 byte PDF when using admin interface multi-page PDF, but not when using single page. If I create a single page doc in admin interface, 0 byte. Same page generated from the page itself, works.

Oddly, this is only on one of the trac sites, even though the two have identical trac.ini and a check of permissions seems to show they are the same.

### comment:33 Changed 7 years ago by anonymous

With my problem, seems to be content related. Will try to narrow it down. The site with the 0 byte PDF in admin interface does seem to be page dependent.

### comment:34 Changed 7 years ago by anonymous

BINGO.

WikiToPDF fails ONLY if the page did not includes a title in wiki syntax. That is, = Page Title =

I imagine some internal logic was requiring it for building the document index.

### comment:35 Changed 7 years ago by izzy

I just had a similar problem today. It turned out it could not write to /tmp/htmldoc/. However that happened: There was no such directory, but a file by the very same name (/tmp/htmldoc). Removing that file solved the issue for me.

From above comments, I'm pretty sure this will not help all of you - but it might be worth a look at least.

### comment:36 Changed 7 years ago by izzy

One more source to check: I just figured out the "0 byte prob" also happens when the defined cover pages do not exist, so you might want to check that as well.

### comment:37 Changed 6 years ago by anonymous

You should install clearsilver and python-clearsilver. both packages.
