[issue10932] distutils.core.setup - data_files misbehaviour ?

[Prashant Kumar]

Prashant Kumar  added the comment:

Certainly, a test is needed to check that ('config', ['cfg/data.cfg']) would 
create a file in config/data.cfg and not config/cfg/data.cfg.

Though, I've added a patch 'test_command_sdist.diff' for the changes made in 
'patch.diff'.

[issue11907] SysLogHandler can't send long messages

[Vinay Sajip]

Vinay Sajip  added the comment:

The entire part of emit() which sends to the socket is wrapped in an except: 
which should catch all except KeyboardInterrupt and SystemExit. The except 
clause calls the handleError method of the handler. See

http://hg.python.org/cpython/file/fa277cbd66bb/Lib/logging/handlers.py#l804

So I can't see exactly what's happening, and moreover I can't reproduce this on 
Linux even when sending messages of > 16384 on the Unix socket. I don't have 
access to a FreeBSD system.

Can you do a little more investigation, since I'm not sure what your source 
says? (The line nos. don't seem to match up exactly - in Mercurial, line 808 is 
an except socket.error clause).

[issue11907] SysLogHandler can't send long messages

[Lukáš Lalinský]

Lukáš Lalinský  added the comment:

It seems that I was wrong, the exception is indeed not propagated to the 
application, but handled by the handleError() method. I was confused by seeing 
the traceback in my uWSGI log file.

I'm unable to find a way to determine the maximum allowed syslog message size, 
otherwise the proper behavior would be probably to truncate the message. 
Specifically on FreeBSD, the clib source code seems to be using a buffer with 
2048 bytes for the whole syslog line and 1024 bytes for the message formatting, 
so they are just arbitrary numbers. :(

There probably isn't a way to solve this cleanly. Truncating the message would 
be much preferable to dropping it, but I really don't know what would be the 
right size. 

I'll write a LocalSysLogHandler for me that uses the syslog module.

Regarding the line numbers, this is the version corresponding to the 2.7.1 
release -

[issue11907] SysLogHandler can't send long messages

[Vinay Sajip]

Vinay Sajip  added the comment:

I've managed to get access to a FreeBSD system and done some investigation. The 
system is working as designed, and the error message is being printed by the 
handleError() method of the handler. To handle the exception differently, you 
either set logging.raiseExceptions to False (which will cause logging to 
swallow the exception) or you need to implement your own handler which takes 
appropriate action (e.g truncates the message).

Closing as invalid.

[issue11912] Python shouldn't use the mprotect() system call

[Nils Breunese]

New submission from Nils Breunese :

When I try to run iotop [0] on CentOS 5.6 on a kernel with grsecurity [1] then 
iotop won't start because grsecurity is blocking Python because of its use of 
the mprotect() system call.

Please see 
http://www.atomicorp.com/wiki/index.php/ASL_FAQ#grsec:_denied_RWX_mprotect for 
more information. The authors of this hardened Linux kernel suggested to file a 
bug with Python because using mprotect() is apparently a very bad thing to do.

Well, does Python itself run ok? That Python script could use
third-party extension modules which issue the offending mprotect() call.

I haven't had any problems with other Python applications like this, Python

I just noticed that iotop has a dependency on python-ctypes, which sounds like 
it could be iotop doing the mprotect() calls via ctypes. Does that make sense?

Since urllib is protocol agnostic it should behave the same with FTP, right?

So, where to fix? Change the addinfourl() to become itrable or change the

[issue11914] pydoc modules/help('modules') crash in dirs with unreadable subdirs

[Ben Okopnik]

New submission from Ben Okopnik :

Long-standing problem (happens in every Python version I've tested). The usual 
situation is when invoking Python (and then "help('modules')") or "pydoc 
modules" in /tmp, but also happens when located anywhere with unreadable 
subdirs:

ben@Jotunheim:~$ mkdir /tmp/foo; cd /tmp/foo
ben@Jotunheim:/tmp/foo$ mkdir bar; sudo chmod 000 bar
[sudo] password for ben: 
ben@Jotunheim:/tmp/foo$ pydoc modules

Please wait a moment while I gather a list of all available modules...

Traceback (most recent call last):
  File "/usr/bin/pydoc2.6", line 5, in 
pydoc.cli()
  File "/usr/lib/python2.6/pydoc.py", line 2309, in cli

  File "/usr/lib/python2.6/pydoc.py", line 1765, in help

  File "/usr/lib/python2.6/pydoc.py", line 1886, in listmodules

  File "/usr/lib/python2.6/pydoc.py", line 1937, in run
for importer, modname, ispkg in pkgutil.walk_packages(onerror=onerror):
  File "/usr/lib/python2.6/pkgutil.py", line 105, in walk_packages

  File "/usr/lib/python2.6/pkgutil.py", line 211, in iter_modules
for fn in os.listdir(path):
OSError: [Errno 13] Permission denied: './bar'

Proposed patch:

Seems like an easy fix. In Python 3.1.2, change line 206 in 
/usr/lib/python3.1/pkgutil.py from

if not modname and os.path.isdir(path) and '.' not in fn:

to

if not modname and os.path.isdir(path) and '.' not in fn and os.access(path, 
os.R_OK):

Other versions much the same (although the specified line number will probably 
be different.)

[issue11907] SysLogHandler can't send long messages

[Vinay Sajip]

Vinay Sajip  added the comment:

> I'll write a LocalSysLogHandler for me  that uses the syslog module.

Sure, but bear in mind that on some Linux systems at least, the syslog module 
has thread safety issues because the underlying C APIs are not thread-safe. 
(I'm 
not sure of the situation on FreeBSD.) This shouldn't be a problem if the only 
calls to the module are from the handler, since logging has handler locks - but 
it could be a problem if other code in your process calls syslog APIs directly.
