Matplotlib Fails Unit Tests #61

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
What steps will reproduce the problem?
1. run matplotlib.test()

What is the expected output? What do you see instead?
I expect the test not fail 50% of the routines. I also expect my local miktex 
install not to ask for missing packages during the test.

What version of the product are you using? On what operating system?
2.7.5.1 64bit on Win7

Please provide any additional information below.
See attachments, ran test in ipython after unanticipated failure of plotting 
script, and then in a clean python console.

in the ipython test, I did not install missing tex packages.
in the python test, I elected to install the missing packages.

Example alert below. I don't think it actually installs the dependency, since 
every new test asks for it.

Sorry for spreading everything out. Here's the same issue, with WinPython on a 
32bit XP machine.

1) The matplotlib test data are no longer included in the official release 
versions of the matplotlib binaries because of their size. You can manually 
install the test data from the matplotlib source distribution.
2) Matplotlib tests require Inkscape, GhostScript and MikTeX to be installed 
and in the PATH. 
3) MikTeX must be recent and should be fully installed or configured not to ask 
for missing packages during the test. 
4) Due to the large number of open files, it might be necessary to 
`ctypes.cdll.msvcr[90|100]._setmaxstdio(2000)` before running the tests.

Interesting. I ran the tests to investigate a failure of the pdf backend to 
save several figures from my script. This script ran fine in 2.7.3 python(x,y), 
and runs fine under Xubuntu 13.04 with the same python component versions.

A simple script to save a plot as a pdf works fine, so I'll see if I can 
sanitize and upload my special case that's causing the issue.

Specific error here:

I'm attaching a .7z of the script, datafile, and expected result. This causes 
the error above, but only for this version of winpython (2.7.5.1 x64 on Win7, 
and 2.7.5.1 x86 on WinXP).

It's not clear to me why this is happening. The plotting function produces the 
graphs correctly. It seems that the line pp.savefig(fig) fails in this special 
case.

So, I guess I just uninstall and wait for a rebuild?

Uninstalling, and reinstalling a 1.2.1 binary through the WPPM seemed to fix 
the problem. But there is nothing "done" about this error, and it's not a bug 
in matplotlib.
 Please verify the integrity of your matplotlib release when you get the chance.

It is a bug in matplotlib:v1.2.x. I submitted a PR at 
https://github.com/matplotlib/matplotlib/pull/2144
