I have a PHP script which authenticates a user and I am trying to get the
PHP script to wrap a Python script using matplotlib.
As it is, the script mostly works when invoked from the command line or as
its own CGI script. When I call it from a PHP script, it doesn't produce
output, and testing found that when I call a Python script from a PHP
script, output works before but not after "import matplotlib": if the PHP
script calls a script of:
#!/usr/bin/python
print "Before import matplotlib."
import matplotlib;
print "After import matplotlib."
the first print statement succeeds but the second one fails; the server log
shows a crash of:
Before import matplotlib.Traceback (most recent call last):

RuntimeError: Failed to create /root/.matplotlib; consider setting

I think this error is somewhat misleading; it persisted after I ran a "chmod
-R 1777 /root/.matplotlib".
What is the proper way to adjust things so matplotlib will be happy with its
.matplotlib directory?

Just throwing out a suggestion here: You could try putting a matplotlibrc file in the same directory as your Python script -- it will use that instead of the one in ~/.matplotlib.

Tried that and reran it; I'm getting substantially the same stacktrace:
File "/home/jhayward/bintmp/test.py", line 5, in <module>
import matplotlib;
File "/usr/lib64/python2.5/site-packages/matplotlib/__init__.py", line
639, in <module>
rcParams = rc_params()
File "/usr/lib64/python2.5/site-packages/matplotlib/__init__.py", line
562, in rc_params
fname = matplotlib_fname()
File "/usr/lib64/python2.5/site-packages/matplotlib/__init__.py", line
513, in matplotlib_fname
fname = os.path.join(get_configdir(), 'matplotlibrc')

raise RuntimeError("Failed to create %s/.matplotlib; consider setting

RuntimeError: Failed to create /root/.matplotlib; consider setting
MPLCONFIGDIR to a writable directory for matplotlib configuration data
It's /path/matplotlibrc and not /path/.matplotlibrc or anything like that?

I found a reason for the behavior: The script was running as user apache, but trying to open /root/.matplotlib, and /root was mode 0700. It stopped crashing on import after I made /root mode 0711. This is somewhat surprising behavior to me; shouldn't it be defaulting to something besides expected access to ~root?

It's supposed to default to the current user's home directory. Perhaps "apache" doesn't have a home directory?

Below is the code in mpl that actually does the lookup. To get to the
bottom of this, I would try to figure out in your Apache/PHP environment
what
a) what os.path.expanduser("~") gives
b) what the values of the environment variables "HOME", "USERPROFILE",
"USER", and "TMP" are.
I suspect either matplotlib is not getting run under user 'apache' as it
should, or there is something fishy about the environment.
Cheers,
Mike

It looks like an apache that thinks it's root:
os.system("whoami")
print "<br>"
print os.geteuid()
print "<br>"
print os.getuid()
print "<br>"
print os.path.expanduser("~")
print "<br>"
print os.getenv("HOME")
print "<br>"
print os.getenv("USERPROFILE")
print "<br>"
print os.getenv("USER")
print "<br>"
print os.getenv("TMP")
print "<br>"
produces:
apache
81
81
/root
/root
None
root
None
So I should adjust the system so a confused apache-owned process that thinks
it's root will run? Or are there features to ask PHP to spawn subprocesses
that know who they're running as? (or is that something beside the point of
this list?)

This is getting a bit outside of my knowledge area, but it does look like the environment variables are not being set up correctly when the Python process is run. This is probably a more general apache/mod_php sort of question, but it would be great to post the answer here so we can add a solution to the matplotlib FAQ.
