Detail

If htmldoc sends a minor error, PublishContrib does not give the resulting PDF to the user even though the PDF has been created.

Example: I have a topic with a too wide picture. When I run htmldoc on the prompt, I get the following message:

$ htmldoc --webpage --links --linkstyle plain --outfile /tmp/tt.pdf /home/httpd/twiki/export/Mettenmeier_940/WebHome.html
ERR014: Image on page 1 too large - truncation or overlapping may occur!
PAGES: 1
BYTES: 226000

Nevertheless the PDF file has been created.

When I try to create a PDF from that topic with the help of PublishContrib I get the following error in the browser:

Content-type: text/plain TWiki detected an internal error - please check your TWiki logs and webserver logs for more information. htmldoc failed: 1path

In the error.log I get the following:

The PDF file is created but it is not handed over to the user.

Of course, the initial error comes out of htmldoc. But I think, this error message should be handeld by the plugin: The user may get a warning but the resulting PDF file should be handed over to the user.

-- TWiki:Main/MarkusHesse - 12 Feb 2007

PublishContrib only reacts to a non-zero exit code coming from htmldoc (in this case, error code 1), which is normally taken as indicating a fatal error. If we have to parse the error message from htmldoc, that's pretty crap.

Anyone got a patch that fixes this? I don't use PDF output myself, so the motivation isn't strong. The obvious hack is to comment out this line from pdf.pm:

die "htmldoc failed: $exit/$data/$@" if $exit;

-- TWiki:Main.CrawfordCurrie - 13 Feb 2007

OK, I refactored the reporter to make this less aggressive, but it is an error.
