0.99.1.2: error in afm.py

Rich_Shepard1 · October 17, 2011, 5:57pm

After a long hiatus I'm again working on an application and just upgraded
matplotlib from 0.98.5.2 to 0.99.1.2. However, there's an error on start up
that I need your help in resolving.

There are many dozens of lines containing:

Found an unknown keyword in AFM header (was Underline)

The traceback (in its entirety) shows:

Rich,

In the afm.py file, a before line 167, can you print the value of the “line” variable and tell us what it is?

On line 166, I want you to put “print ‘Line:’, line”. Then, rerun your program and report back what the output of that print statement.

Ben,

Sorry I mis-understood your request.

I redirected the output to a file 'error.log' and it contains 104,777
lines from the 'print line' command. I can gzip it and send it to you off
the list but it's 5.5M in size.

When I grep for Underline in error.log it's not found. That seems to be
the unknown keyword.

How would you like me to proceed?

Thanks,

Rich

I only need the last line printed by that print statement. I want to see how the parsing failed.

Here are the last 3:

I see there's no character in the last line. Isn't that interesting!

Hi Rich,

After a long hiatus I'm again working on an application and just upgraded
matplotlib from 0.98.5.2 to 0.99.1.2.

Is there a particular reason you just upgraded to a version of
matplotlib that is almost 2 years old now? Matplotlib 1.1.0 was
released a few weeks ago, so it's strange that you did not upgrade to
it, or at least to 1.0.1, which came out in January. I'm not certain
that the issue you're running into has been fixed, but there have
certainly been lots of changes. I also want to make sure that there
isn't some stale pointer to an old version of matplotlib out there -
so can you let us know what procedure you used to do the upgrade?

best,

Paul,

Apparently, a bunch of the back-n-forth between myself and the OR went off-list. The problem is with the AFM font files packaged with mpl. afm.py is doing the correct thing by failing to parse an invalid line. However, I don’t know much about AFM files and where they come from package-wise to know where to file a bug report.

Cheers,

Paul_Ivanov3 · October 22, 2011, 1:42am

What's weirder, is that 127 is a control character (Delete), and not
meant to be a printable character.

Maybe you already figured this out in following up with Ben, but if
not, can you 'print fh.name' before the while 1: in
_parse_char_metrics so we find out which .afm file is the culrpit

Paul,

Yes, the reason was 0.99.1.2 was on the SlackBuilds.org site, so I didn't
check to see if it was the current version.

... so it's strange that you did not upgrade to it, or at least to 1.0.1,
which came out in January.

I just did: 1.1.0 is now installed, but I still have the same problem
trying to run my model.

I'm not certain that the issue you're running into has been fixed, but
there have certainly been lots of changes. I also want to make sure that
there isn't some stale pointer to an old version of matplotlib out there -
so can you let us know what procedure you used to do the upgrade?

I modified the matplotlib.SlackBuild script to remove the old patch and
the non-existant file names INTERACTIVE and KNOWN_BUGS. It built and
upgraded just fine.

Ben's been helping by asking for information that might assist in
isolating the source of the problem. Since I am now using version 1.1.0 I'll
resend the error report.

There are multiple lines reading:

Found an unknown keyword in AFM header (was Underline)

followed by the traceback:

I will certainly add diagnostic code requested by you, Ben, and anyone
else and report the results when trying to run the model. I do need to fix
this and have no idea what's behind the problem.

this and have no idea what's behind the problem.

The traceback is due to a nonprinting character being included in one
of the fonts on your system - we just need to figure out which one.
Change my request to add 'sys.stderr.write(fh.name)' before the 'while
1:' in
_parse_char_metrics - just so we don't have any buffering issues. The
last file you see printed there will be the one that's causing the
issue. You can then try removing it, or sending it back to the list
(or both) so we can see what happened.

The other issue you're seeing ("unknown keyword in AFM header") is
also likely caused by bad font files.

From your error log that Ben forwarded to the list - I'm a bit

suspicious that two of the errors came from an afm file that ships
with matplotlib, in particular matplotlib-error-trace.txt starts off
with:

  FILENAME:
  /usr/lib/python2.6/site-packages/matplotlib/mpl-data/fonts/afm/pagko8a.afm
  Found an unknown keyword in AFM header (was Underline)
  Found an unknown keyword in AFM header (was Underline)

This shouldn't be the case, as I can verify that the keywords aren't
just Underline - they are as follows:

  $ grep Under matplotlib/mpl-data/fonts/afm/pagko8a.afm
  UnderlinePosition -100
  UnderlineThickness 50

and that particular file has not been change in matplotlib since
February of 2007

So my wild guess is that something changed your afm files. Can you
check that your pagko8a.afm matches the one in
https://raw.github.com/matplotlib/matplotlib/master/lib/matplotlib/mpl-data/fonts/afm/pagko8a.afm
- and if they don't match, check that using the original pagko8a.afm
makes at least that error go away?

As another possible solution (maybe this is already done, but worth a
potshot), you could try switching USE_FONTCONFIG to True in
font_manager.py as per the docstring there:

Experimental support is included for using `fontconfig` on Unix
variant platforms (Linux, OS X, Solaris). To enable it, set the
constant ``USE_FONTCONFIG`` in this file to ``True``. Fontconfig has
the advantage that it is the standard way to look up fonts on X11
platforms, so if a font is installed, it is much more likely to be
found.)

best,

Paul,

The last file printed before the traceback is
/usr/share/fonts/atmfonts/kidsm.afm. When I mv that to Xkidsn.afm it still
shows up. I'm also seeing the same error in a number of other atmfonts. Some
in /usr/X11/lib/X11/fonts/atmfonts, which is a soft link to
/usr/share/fonts/atmfonts, and other errors in the soft links in
~/.fonts/atmfonts.

Would you like a copy of kidsn.afm?

Thanks,

sure. let's take a look.

What about the .afm that ships with matplotlib which also caused
problems - did you verify that the one you have is the same as the one
under version control in matplotlib?

What about the .afm that ships with matplotlib which also caused problems
- did you verify that the one you have is the same as the one under
version control in matplotlib?

Well, the source file came from the matplotlib Web site, so I assume that
it/they are OK. The SlackBuild script essentially re-packages the download
as a Slackware package so it can be managed more easily and consistently
with other packages.

those two properties should not have spaces in them - according the

is what matplotlib expects - and this is the source of all of the
"'Found an unknown keyword in AFM header (was Underline)" warning that
you saw.

I still find it strange that this character is even in the font file
- maybe it had a value other than just space, but copy pasting made it
appear as such? Please resend the file as an attachement so we can
verify.

In the meantime - this patch should get around trying to parse any
such files without causing tracebacks

in lib/matplotlib/afm.py, after the line that says 'if
line.startswith('Comment'): continue' add another line that says 'if
line.startswith('C 127'): continue'

If this was really the case, we should not have been seeing "Found an
unknown keyword in AFM header (was Underline)" for the afm files that
ship with matplotlib (but we were on your machine - so something
changed them).

Please diff your pagko8a.afm against
https://raw.github.com/matplotlib/matplotlib/master/lib/matplotlib/mpl-data/fonts/afm/pagko8a.afm

Paul,

That specific font is apparently kid oriented (not surprising as it comes
from Corel a long time ago). I can delete it and never miss it.

OK. Done.

There's no difference between

Thanks,

Ok - strange that we saw a lot of errors caused by probably the same
deviation from the AFM standard in several other files as indnicated
by the error file Ben posted earlier in this thread.

C 127 ; WX 262 ; N ; B 64 506 246 730 ;

so no more tracebacks?

Well, that's a mystery... why did you previously see a "Found an
unknown keyword in AFM header (was Underline)" message for it...

so no more tracebacks?

Don't know. I'm processing accounts payable, beating up a client who's
late paying an invoice, trying to figure out which R package/function I
need, and more. It's been a rather crappy day, if you must know the truth.

I'll try again tomorrow morning before I head to the dentist.

Well, that's a mystery... why did you previously see a "Found an unknown
keyword in AFM header (was Underline)" message for it...

You ask moi? I've no idea at all! That's why I count on you experts to
tell me why.

Thanks much, Paul,

Rich
