[issue4953] cgi module cannot handle POST with multipart/form-data in 3.0
Pierre Quentel pierre.quen...@gmail.com added the comment: Hi, I have started working on the port of a simplified version of Karrigell (a web framework) to Python3. I experienced the same problem as the other posters : in the current version, file upload doesn't work. So I've been working on the cgi module for a few days and now have a version which correctly manages file uploads in the tests I made The problem in the current version (3.2b2) is that all data is read from sys.stdin, which reads strings, not bytes. This obviously can't work properly to upload binary files. In the proposed version, for multipart/form-data type, all data is read as bytes from sys.stdin.buffer ; in the CGI script, the Python interpreter must be launched with the -u option, as suggested by Amaury, otherwise sys.stdin.buffer.read() only returns the beginning of the data stream The headers inside the multipart/form-data are decoded to a string using sys.stdin.encoding and passed to a FeedParser (which requires strings) ; then the data is read from sys.stdin.buffer (bytes) until a boundary is found If the field is a file, the file object in self.file stores bytes, and the attribute value is a byte string. If it is not a file, the value is decoded to a string, always using sys.stdin.encoding, as for all other fields for other types of forms Other cosmetic changes : - replaced while 1 by while True - replaced if type(value) == type([]) by if isintance(value,list) Attached file : zip with cgi_new.py and tests in a folder called http Tested with Python 3.2b2 (r32b2:87398, Dec 19 2010, 22:51:00) [MSC v.1500 32 bit (Intel)] on win32 ; files and CGI scripts served by Apache 2.2 -- nosy: +quentel Added file: http://bugs.python.org/file20217/http.zip ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue4953 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue10348] multiprocessing: use SysV semaphores on FreeBSD
STINNER Victor victor.stin...@haypocalc.com added the comment: More info about FreeBSD. sysctl p1003_1b.sem_nsems_max gives the maximum number of POSIX semaphores (per process? system wide?). Since FreeBSD 8.1, sudo sysctl -w p1003_1b.sem_nsems_max=256 can be used to change this limit at runtime. Before FreeBSD 8.1, SEM_MAX constant should be changed in the kernel source code, and the kernel have to be recompiled. (p1003_1b.sem_nsems_max is not configurable in /etc/sysctl.conf, it is an hardcoded limit). Before FreeBSD 8.0, the POSIX semaphores are disabled by default: the kernel have to be compiled using P1003_1B_SEMAPHORES option.

[issue10348] multiprocessing: use SysV semaphores on FreeBSD
STINNER Victor victor.stin...@haypocalc.com added the comment: OpenBSD. According to Martin, OpenBSD doesn't implement POSIX semaphores. --- I don't have an installation of OpenBSD, but... In FreeBSD, POSIX semaphores are implemented in sys/kern/uipc_sem.c. In http://www.openbsd.org/cgi-bin/cvsweb/src/sys/kern/ that file doesn't exist. Also, in FreeBSD's limits.h, _POSIX_SEM_NSEMS_MAX is defined (surprisingly to 256); in http://www.openbsd.org/cgi-bin/cvsweb/~checkout~/src/include/limits.h?rev=1.15;content-type=text/plain this constant doesn't appear. So ISTM that OpenBSD doesn't implement POSIX semaphores.

[issue10716] Modernize pydoc to use CSS
Ezio Melotti ezio.melo...@gmail.com added the comment:
A few comments about css_v2.diff:
1) when the value is '0', there's no need to specify the unit (e.g. 0em);
2) when the color is specified the background-color should be specified as well
(and vice versa);
3) hex colors (e.g. #00FF00) should be preferred to named colors (e.g. gray);
4) some selectors and properties don't work with older browsers (e.g. E F or
min-width);
5) there are a few empty dl.*{} that I would remove (unless you plan to fill
them later);
6) the style I prefer for CSS is:
selector {
property: value;
}
Regarding the HTML:
1) using an HTML 4.01 strict doctype would be better;
2) all the style-related attributes and elements should be removed (e.g
bgcolor, valign, font);
3) using .red { color: red; } is not a good idea. Classes' names should
describe the role of the element (e.g. header, entry) and not their style
(otherwise when you want to change the page with a blue theme you'll end up
with a .red { color: blue; }). If the colors are passed directly to the HTML
they should be removed and left to the CSS(s) only. I don't know the code well
enough to say if this is doable and/or if it requires a deprecation first;
4) the lis in html_header() should be closed, same for all the other elements
that support a closing tag, even if optional (e.g. dt, dd);
There are also some minor incontinences in the indentantion, e.g.:
+link_list = ['a href=%s.html%s/a' % (name, name)
+for name in sys.builtin_module_names
+if name != '__main__']
+contents = [html.index_columns('Built-in modules',
+link_list, css_class='section modules')]
+link_list = ['a href=%s.html%s/a' % (name, name)
+ for name in sorted(Helper.keywords.keys())]
(the contents one is indented correctly), and some extra space after the '('.

R. David Murray rdmur...@bitdance.com added the comment: Thank you very much for working on this! I'll try to take a look at the patch soon. A couple quick comments based on your posting: first, the email module now has a BytesFeedparser that will accept a byte stream, which I hope might simplify your patch. Second, it would be very helpful if you could upload your patch as an 'svn diff' against the current py3k trunk (see python.org/dev for details on how to do that). That will make review and application of the patch much much simpler. (This would be true even if more of the code in cgi.py has changed than not.) If you don't want to set up an svn checkout, then a context diff against the copy of cgi.py you started with would be second best.

New submission from Ross Lagerwall rosslagerw...@gmail.com:
There is an issue where if a python program closes all the std. file
descriptors (e.g. a daemon) and then uses the subprocess module, the file
descriptors may not be set up properly in the subprocess. This may actually be
a fairly common use case in a daemon program that needs to run a subprocess and
set up pipes to it.
Here is an example:
import os, subprocess, sys
x=os.open('/dev/null', os.O_RDWR)
os.close(0)
os.close(1)
os.close(2)
res = subprocess.Popen([sys.executable, -c,
'import sys;'
'sys.stdout.write(apple);'
'sys.stdout.flush();'
'sys.stderr.write(orange)'],
stdin=x,
stdout=subprocess.PIPE,
stderr=subprocess.PIPE).communicate()
with open('/tmp/out', 'w') as f:
f.write(repr(res) + '\n')
f.write(repr((b'apple', b'orange')) + '\n')
The expected output in /tmp/out is:
('apple', 'orange')
('apple', 'orange')
but we get:
(b'', bFatal Python error: Py_Initialize: can't initialize sys standard
streams\nOSError: [Errno 9] Bad file descriptor\n)
(b'apple', b'orange')
The problem comes about where the calls are made (this applies to the python
c versions):
os.dup2(p2cread, 0)
os.dup2(c2pwrite, 1)
os.dup2(errwrite, 2)
if c2pwrite or p2cread or errwrite is the same as what it's being dupped() to
(eg if c2pwrite == 1) then the dup2 call does nothing. But, if we're using
pipes, the close-on-exec flags are set initially and the dup2() call would
normally remove the flag but it doesn't.
Attached is a patch which basically uses fcntl if necessary to remove the
close-on-exec flag, and tests.

Antoine Pitrou pit...@free.fr added the comment: Attached is a patch which basically uses fcntl if necessary to remove the close-on-exec flag, and tests. Python adds extra output at the end of stderr when compiled in debug mode. Therefore you first have to strip that output, like this: out, err = subprocess.Popen(...).communicate() err = support.strip_python_stderr(err) self.assertEqual((out, err), (b'apple', b'orange')) Otherwise, looks good, thank you. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue10806 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue10807] `b'dGVzdA==\n'.decode('base64')` raise exception
STINNER Victor victor.stin...@haypocalc.com added the comment:
base64, bz2, hex, quopri, rot13, uu and zlib codecs (reintroduced recently by
r86934, issue #7475) cannot be used by str.encode/bytes.decode, but with
.transform() and .untransform() methods of bytes and str objects. But these
methods were removed by r87176.
The last solution to use base64 codec is:
import codecs
codecs.lookup('base64').decode(b'YWJj\n')[0]
b'abc'
codecs.lookup('base64').encode(b'YWJj\n')[0]
b'abc'
Or simply use directly the base64 module:
import base64
base64.decodebytes(b'YWJj\n')
b'abc'
base64.encodebytes(b'abc')
b'YWJj\n'
base64, bz2, hex, quopri, rot13, uu and zlib codecs should be removed from
encodings.aliases (because they introduced a confusion for Python 2 users), or
removed completly (because it's easier to use directly the related module, eg.
base64 or zlib).

It turns out the check added in r85137 does not cover tm_year even
though CERT recommends it (see msg107605). These are separate issues
though. I think given where we are in the release cycle, the most
conservative solution would be to simply add a null check as follows.
(I did check that it fixes the crash on OSX.)

Glenn Linderman v+pyt...@g.nevcal.com added the comment: Pierre, thanks for your work on this. I hope a fix can make it in to 3.2. However, while starting Python with -u can help a but, that should not, in my opinion, be requirement to use CGI. Rather, the stdin should be set into binary mode by the CGI processing... it would be helpful if the CGI module either did it automatically, verified it has been done, or at least provided a helper function that could do it, and that appropriate documentation be provided, if it is not automatic. I've seen code like: try: # Windows needs stdio set for binary mode. import msvcrt msvcrt.setmode (0, os.O_BINARY) # stdin = 0 msvcrt.setmode (1, os.O_BINARY) # stdout = 1 msvcrt.setmode (2, os.O_BINARY) # stderr = 2 except ImportError: pass and if hasattr( sys.stdin, 'buffer'): sys.stdin = sys.stdin.buffer which together, seem to do the job. For output, I use a little class that accepts either binary or text, encoding the latter: class IOMix(): def __init__( self, fh, encoding=UTF-8): if hasattr( fh, 'buffer'): self._bio = fh.buffer fh.flush() self._last = 'b' import io self._txt = io.TextIOWrapper( self.bio, encoding, None, '\r\n') self._encoding = encoding else: raise ValueError(not a buffered stream) def write( self, param ): if isinstance( param, str ): self._last = 't' self._txt.write( param ) else: if self._last == 't': self._txt.flush() self._last = 'b' self._bio.write( param ) def flush( self ): self._txt.flush() def close( self ): self.flush() self._txt.close() self._bio.close() sys.stdout = IOMix( sys.stdout, encoding ) sys.stderr = IOMix( sys.stderr, encoding ) IOMix may need a few more methods for general use, print comes to mind, for example. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue4953 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue10809] complex() comments wrongly say it supports NaN and inf
New submission from Andrew Dalke da...@dalkescientific.com: complex(nan) raises ValueError: complex() arg is a malformed string while complex(float(nan)) returns (nan+0j). This was reported in http://bugs.python.org/issue2121 with the conclusion wont fix. complex(inf) has the same behaviors. The implementation in complexobject.c says /* a valid complex string usually takes one of the three forms: float - real part only floatj - imaginary part only floatsigned-floatj - real and imaginary parts where float represents any numeric string that's accepted by the float constructor (including 'nan', 'inf', 'infinity', etc.), and signed-float is any string of the form float whose first character is '+' or '-'. This comment is wrong and it distracted me for a while as I tried to figure out why complex(nan) wasn't working. It should be fixed, with the word including replaced by excluding. I don't have a real need for complex(nan) support - this was of intellectual interest only. Also of intellectual interest, PyPy 1.4 does accept complex(nan) but converts complex(nan+nanj) to (nannanj), so it suffers from the strange corner cases which Raymond points out when advocating for wont fix.

[issue10716] Modernize pydoc to use CSS
Ron Adam ron_a...@users.sourceforge.net added the comment: If the colors are passed directly to the HTML they should be removed and left to the CSS(s) only. I don't know the code well enough to say if this is doable and/or if it requires a deprecation first; We may have to do dome depreciating when it comes to the old HTMLDoc class methods. Would it be possible to depreciate the whole class instead of the separate methods? If so, it would be good if we can squeeze that into 3.2. hint hint Or else we may not be able to finish this until Python 3.4. The empty css elements will be used later. Here is the css_v3.diff for review. I'd like to hear any thoughts about the general html structure and class/id names. Beside validating them, I test with firefox and chromium.

Georg, I disagree with your solution. According to relevant standards, asctime is undefined for year . A compliant implementation can do anything in this case including not null-terminating the internal buffer. With your change, time.strftime will happily replace the first unrelated '\n' with '\0' that it will find beyond the internal buffer. I was considering raising an ValueError if '\n' is not found at 24th position, but this (or a precondition check solution) should wait until 3.3. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue8013 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
