[issue19430] argparse replaces \$ to is passed
New submission from telmich:
When using argparse and the string \$ occurs on the commandline, it is
converted to $. This as definitely wrong and renders argparse useless, if the
input needs to be trusted (i.e. defitinely the same as given into it)'
Example code:
import sys
import argparse
parser = argparse.ArgumentParser()
parser.add_argument('test', nargs='*')
result = parser.parse_args(sys.argv[1:])
print(args = %s % .join(sys.argv))
print(result = %s % result)
Reproduce problem:
[10:41] bento:~% python3 argparse-test.py ps1 PS1='[\t]
\[\033[1m\]\h\[\033[0m\]:\w\$ '
] \[\]\h\[\]:\w\$ 'args = argparse-test.py ps1 PS1='[\t]
\[\033[1m\]\h\[\033[0m\]:\w$ '
result = Namespace(test=['ps1', PS1='[\\t]

[issue19183] PEP 456 Secure and interchangeable hash algorithm
Nick Coghlan added the comment: Christian's general approach looks fine to me - consolidating the kind hashes (i.e. byte sequences, numbers and pointers) into one place independent of any particular type implementation makes sense to me, and the clear abstraction of What is a hash function? from Python's point of view is a good thing for embedding purposes. If you get the PEP updated accordingly, we should be able to get that formally accepted in fairly short order. (I had some other suggestions in the review, but they aren't relevant to accepting the PEP). Regarding the concerns about a potential performance impact for unaligned memory access, I think that can be better assessed *after* the simpler patch is merged and it's easier for people to get hold of the new hash implementation. However, the PEP should mention the concern, and note it as something we will be keeping a close eye on during the beta period. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue19183 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue19430] argparse replaces \$ with $ (if in commandline)
R. David Murray added the comment: Indeed, you can see in the original posting that the \ is already gone from the dollar in sys.argv, so argparse has nothing to do with it.

[issue19435] Directory traversal attack for CGIHTTPRequestHandler
New submission from Alexander Kruppa:
An error in separating the path and filename of the CGI script to run in
http.server.CGIHTTPRequestHandler allows running arbitrary executables in the
directory under which the server was started.
The problem is that in CGIHTTPRequestHandler we have:
def run_cgi(self):
Execute a CGI script.
path = self.path
dir, rest = self.cgi_info
i = path.find('/', len(dir) + 1)
where path is the uncollapsed path in the URL, but cgi_info contains the first
path segment and the rest from the *collapsed* path as filled in by is_cgi(),
so indexing into path via len(dir) is incorrect.
An example exploit is giving the request path:
///badscript.sh/../cgi-bin/cgi.sh
Note that Firefox and wget at least simplify the path in the request; to make
sure this exact path is used, do for example:
(echo GET ///badscript.sh/../cgi-bin/cgi.sh HTTP/1.1; echo) |
telnet localhost 4443
This causes the CGIHTTPRequestHandler to execute the badscript.sh file in the
directory in which the server was started, so script execution is not
restricted to the cgi-bin/ or htbin/ subdirectories.

[issue19438] Where is NoneType in Python 3?
New submission from mpb: types.NoneType seems to have disappeared in Python 3. This is probably intentional, but I cannot figure out how to test if a variable is of type NoneType in Python 3. Specifically, I want to write: assert type (v) in ( bytes, types.NoneType ) Yes, I could write: assert v is None or type (v) is bytes But the first assert statement is easier to read (IMO). Here are links to various Python 3 documentation about None: [1] http://docs.python.org/3/library/stdtypes.html#index-2 [2] http://docs.python.org/3/library/constants.html#None Link [2] says: None The sole value of the type NoneType. However, NoneType is not listed in the Python 3 documentation index. (As compared with the Python 2 index, where NoneType is listed.) [3] http://docs.python.org/3/library/types.html If NoneType is gone in Python 3, mention of NoneType should probably be removed from link [2]. If NoneType is present in Python 3, the docs (presumably at least one of the above links, and hopefully also the index) should tell me how to use it. Here is another link: [4] http://docs.python.org/3/library/stdtypes.html#bltin-type-objects The standard module types defines names for all standard built-in types. (Except class 'NoneType' ???) None is a built-in constant. It has a type. If None's type is not considered to be a standard built-in type, then IMO this is surprising(!!) and should be documented somewhere (for example, at link [4], and possibly elsewhere as well.)

[issue19438] Where is NoneType in Python 3?
mpb added the comment: Of your 4 suggestions, I mentioned #3 and #4 in my post. They are less readable, IMO. 1 and 2 are nicer, but both have an extra set of nested parenthesis. While I appreciate the suggestions, I submitted this as a documentation bug, because I think I should be able to find these suggestions somewhere in the Python 3 documentation, at one (or more) of the links I included in my bug report. Also, the Python 3 documentation does mention NoneType, and if NoneType is not part of Python 3, I claim this is an error in the documentation. And then, there is my personal favorite work-around: NoneType = type (None)# only needed once assert type (v) in ( bytes, NoneType ) Or (perhaps more confusingly, LOL!): none = type (None) assert type (v) in ( bytes, none ) isinstance is more confusing because it takes two arguments. Whenever I use it I have to think, isinstance vs instanceof, which is Python, which is Java? (And I haven't used Java seriously in years!) And then I have to think about the order of the arguments (v, cls) vs (cls, v). type is just simpler than isinstance. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue19438 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue19439] Build _testembed on Windows
New submission from Zachary Ware: Here's a patch that builds _testembed on Windows and adjusts test_capi to not skip EmbeddingTests on Windows. The .vcxproj is based on _freeze_importlib, with when to build settings lifted from _testimportmultiple. The patch also adjusts test_capi.EmbeddingTests.test_forced_io_encoding such that it doesn't blow up completely on Windows (and should still pass anywhere it does currently, though I haven't been able to test anywhere but on Windows yet).

[issue19440] Clean up test_capi
New submission from Zachary Ware: Here's a patch to clean up test_capi a little bit; it removes a __future__ import, converts from test_main to unittest.main, and makes use of subtests to run each _testcapi function. I'll post a separate patch for 3.3; there's just enough difference between branches to make a single patch impossible and merging slightly hairy. -- components: Tests files: test_capi_cleanup.diff keywords: patch messages: 201676 nosy: ezio.melotti, zach.ware priority: normal severity: normal status: open title: Clean up test_capi type: enhancement versions: Python 3.3, Python 3.4 Added file: http://bugs.python.org/file32415/test_capi_cleanup.diff ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue19440 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

Charles-François Natali added the comment: Also, unless people haven't been reporting other errors, these buildbots have been stable up until recently Well, the fact that several tests - which were working just fine - started failing randomly recently (like test_concurrent_futures, test_subprocess) is a strong hint that the culprit is the buildbot (I mean, the test_selectors failure just calls epoll_wait(): there is a known overflow for epoll_wait() timeout, but for large timeout values, not 2s).
