[issue13647] Python SSL stack doesn't securely validate certificate (as client)
Dan Kaminsky d...@doxpara.com added the comment: There is a new match_hostname that doesn't implement all the required, standard SSL/TLS Client security checks that should be done. Indeed, as the name indicates, it just checks the hostname. Please detail what the other security checks are (bonus points if you provide a patch + tests). You need to check expiration date of the cert in question, and I suppose invocation date as well. You need to look at each of the CNs in the subject name, as well as each of the DNSname types in the SAN extension. You *absolutely must* make sure that each of the intermediate certificates has Basic Constraints: CA set to True. Otherwise a certificate for foo.com can sign for bar.com (this keeps happening). You should support the Name Constraints extension, that allows certificates to sign for a subset of names. Nobody really uses this, because reliability is so low though. It has been noticed by the well known security researcher Dan Kaminsky What's the URL for this? I'll see your URL and raise you a submitted bug report with recommendations. It seems to get better results than posting random whining on a web page somewhere :) A) Integrate the Mozilla CA pack into Python, updating it with each security release.

[issue13655] Python SSL stack doesn't have a default CA Store
New submission from naif n...@globaleaks.org: For the certificate store: Can we eventually agree to bind a default CA-store to a Mozilla verified one? Mozilla in handling Firefox does a great job in keeping CA-store up-to-date. Integrating default mozilla CA-store with Python builds could be a nice way, it's just a matter of integrating into the build-system the download/fetching of default Mozilla store. At least the language base it's default on a trusted entity to manage, cross-platform, the CA-store for TLS/SSL. The mainteinance of the CA-store would be delegated to Mozilla that has been demonstrated to be independent and very security conscious, removing dirty CA-store (like Diginotar after Iranian compromise). That way 90% of case of of SSL/TLS certificate validation will be managed and by default it would be possible to enable secure SSL/TLS client checking like described in http://bugs.python.org/issue13647 . -- components: Library (Lib) messages: 150142 nosy: naif priority: normal severity: normal status: open title: Python SSL stack doesn't have a default CA Store versions: Python 2.6, Python 2.7, Python 3.1, Python 3.2, Python 3.3, Python 3.4 ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue13655 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue6983] Add specific get_platform() for freebsd
Stef Walter s...@memberwebs.com added the comment: Good plan. So the issue is: * Platform specific eggs are built containing a path that has the full patch level of the freebsd kernel, like 8.2-RELEASE-p2. The -p2 part is updated for every security patch of FreeBSD. * Thus when you apply a security patch to FreeBSD, platform specific eggs built for that version of FreeBSD (before the security patch was applied) are no longer considered compatible. FYI, FreeBSD has an unwritten policy of keeping all 8.x releases backwards compatible with one another. So platform specific eggs built for 8.1 would work without inherent problems on 8.2 or 8.3. But at the very least, platform specific eggs should not be dependent on the patch level of the FreeBSD kernel.

[issue13653] reorder set.intersection parameters for better performance
Andrew Dalke da...@dalkescientific.com added the comment:
My belief is that the people who use set.intersection with more than two terms
are 1) going to pass in a list of sets, and 2) don't care about the specific
order.
To check the validity of my belief, I did a Google Code Search to find cases of
people using set intersection in Python. I searched for set\.intersection\(\*
and \.intersection\(.*\, lang:^python$, among others.
I am sad to report that the most common way to compute set.intersection(*list)
is by using reduce, like:
possible = (set(index[c]) for c in set(otp))
possible = reduce(lambda a, b: a.intersection(b), possible)
That comes from:
git://github.com/Kami/python-yubico-client.git /yubico/modhex.py
and similar uses are in:
git://github.com/sburns/PyCap.git /redcap/rc.py
http://hltdi-l3.googlecode.com/hg//xdg/languages/morpho/fst.py
http://dsniff.googlecode.com/svn/trunk/dsniff/lib/fcap.py
As well as in the Rosetta Code example for a simple inverted index, at:
http://rosettacode.org/wiki/Inverted_index#Python
This was also implemented more verbosely in:
http://eats.googlecode.com/svn/trunk/server/eats/views/main.py
intersected_set = sets[0]
for i in range(1, len(sets)):
intersected_set = intersected_set.intersection(sets[i])
and
http://iocbio.googlecode.com/svn/trunk/iocbio/microscope/cluster_tools.py
s = set (range (len (data[0])))
for d in zip(*data):
s = s.intersection(set(find_outliers(d, zoffset=zoffset)))
return sorted(s)
In other words, 7 codebases use manual pairwise reduction rather than use the
equivalent code in Python. (I have not checked for which are due to backwards
compatibility requirements.)
On the other hand, if someone really wants to have a specific intersection
order, this shows that it's very easy to write.
I found 4 other code bases where set intersection was used for something other
than binary intersection, and used the built-in intersection().
git://github.com/valda/wryebash.git/experimental/bait/bait/presenter/impl/filters.py
def get_visible_node_ids(self, filterId):
if filterId in self.idMask:
visibleNodeIdSets = [f.get_visible_node_ids(filterId) for f in
self._filters]
return set.intersection(*[v for v in visibleNodeIdSets if v is not
None])
return None
http://wallproxy.googlecode.com/svn/trunk/local/proxy.py
if threads[ct].intersection(*threads.itervalues()):
raise ValueError('All threads failed')
(here, threads' values contain sets)
git://github.com/argriffing/xgcode.git/20100623a.py
header_sets = [set(x) for x in header_list]
header_intersection = set.intersection(*header_sets)
http://pyvenn.googlecode.com/hg//venn.py
to_exclude = set()
for ii in xrange(0, len(self.sets)):
if (i (2**ii)):
sets_to_intersect.append(sets_by_power_of_two[i (2**ii)])
else:
to_exclude = to_exclude.union(sets_by_power_of_two[(2**ii)])
final = set.intersection(*sets_to_intersect) - to_exclude
These all find the intersection of sets (not iterators), and the order of
evaluation does not appear like it will affect the result.
I do not know though if there will be a performance advantage in these cases to
reordering. I do know that in my code, and any inverted index, there is an
advantage.
And I do know that the current CPython implementation has bad worst-case
performance.

[issue10513] sqlite3.InterfaceError after commit
Florent Viard fvi...@lacie.com added the comment:
Hi,
I encountered the same regression with python 2.7.
I added a new testcase (testcase2) with another effect of the same problem. It
is a model of what does python-storm when I try to do:
for item in TableA.findall():
TableB.new_item(name=item.name)
connection.commit()
As you can see in the result:
-- One iter --
(0,)
-- One iter --
(1,)
-- One iter --
(0,)
-- One iter --
(1,)
-- One iter --
(2,)
Inside the for loop, there is a reset, but only one time. So entries returned
by for are inconsistents as there could be some duplicated results.
After studying the code, I understood that this regression is caused by the
addition of function call:
pysqlite_do_all_statements(self, ACTION_RESET, 0);
in connection.c: in function: pysqlite_connection_commit
Removing this line, fixes the problem and bring back the old correct behavior.
For the explanation of my case, I understood that:
For the statement of my query, the in_use flag is first set to 1, the first
fetchmany call ran, then the commit triggered the reset of all the statements
that have the in_use flag == 1 and set this flag to 0. So the next fetchmany
call return results from the beginning again without care for the state of the
in_use flag. Then, the next commit don't reset again the statement as its
in_use flag is still == 0.
I think, that the first intention of this modification was more to use the
following call:
pysqlite_do_all_statements(self, ACTION_RESET, 1);
to have the cursor-reset set and so, at next fetch call, triggering exception:
sqlite3.InterfaceError: Cursor needed to be reset because of commit/rollback
and can no longer be fetched from.
But as for using it in rollback, I'm not sure that this behavior is really
useful as sqlite3 looks to be able to correctly handle modifications and cursor
return values.
As an example, the following test with the previous code :
cursor = conn.cursor()
cursorBis = conn.cursor()
cursor.execute('create table first(id primary key);')
for i in range(5):
cursor.execute('insert or replace into first(id) values(?);', (i,))
results = cursor.execute(' select id from first;')
while True:
print -- One iter --
results = cursor.fetchmany()
if not results:
break
for result in results:
print str(result)
cursorBis.execute(' delete from first where id == ?;', (3,))
conn.commit()
That correctly printed:
-- One iter --
(0,)
-- One iter --
(1,)
-- One iter --
(2,)
-- One iter --
(4,)
-- One iter --
So my suggestion is to remove in pysql_connection_commit the call to :
pysqlite_do_all_statements(self, ACTION_RESET, 0);
to bring back the correct old behavior.
And also eventually to remove in pysqlite_connection_rollback the call to :
pysqlite_do_all_statements(self, ACTION_RESET, 1);
What do you think about it?

[issue8604] Adding an atomic FS write API
Charles-François Natali neolo...@free.fr added the comment: If you want atomicity to apply to logging, you must instead guarantee the durability of each write() call, meaning calling fsync() on each logging call Why so? There's no point in calling fsync() after each write, since data is written to a temporary file which won't be visible before rename(): even if you call fsync() after each write, if the file is not properly closed, it won't be committed (i.e.renamed). You just need to call fsync() once before closing the file, and then rename it, to ensure that the committed file version is consistent. In the meantime, you could do whatever you want with the stream (the hypothetical AtomicFile): seek(), read(), etc. I'm not sure many methods besides write will be useful, but for example one could easily imagine that the library expects the passed object to have a fileno() method. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue8604 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue5689] Support xz compression in tarfile module
Nadeem Vawda nadeem.va...@gmail.com added the comment: Yes, that's a good idea. I've been testing a similar change, and it seems to drop the peak memory usage for test_tarfile from around 810MB down to under 200MB. It looks like 2GB genuinely isn't enough to reliably use LZMA compression with preset=9. You might want to use preset=None instead of explicitly saying preset=6, though. This tells LZMAFile to use the default preset, and will allow you to get rid of the if-statement on lines 1821-1823. Something unrelated that I noticed in the surrounding code: gzopen and bz2open validate the mode by testing 'len(mode) 1 or mode not in rw'. This would be simpler as 'mode not in (r, w)' (like you've done in xzopen), and it would accept only r and w (but not or rw). -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue5689 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue8828] Atomic function to rename a file
Charles-François Natali neolo...@free.fr added the comment: I'd prefer an optional flag to rename() too. I really don't like having different functions that achieve the same thing. It's not obvious to infer from 'replace' its real intent, since it doesn't match any standard syscall/library. Ideally, this should be made an option to rename(), especially since on Unix this will just perform a standard rename. Another advantage of options over new functions is that it reduces boilerplate code (i.e. argument parsing, addition to posix_methods, repeating OS idiosyncrasies/conditional compilation blocks, docstring, documentation block...). But I remember Martin thinks that the os module should just be a thin wrapper around underlying syscalls/libraries (but we already have listdir() and friends). -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue8828 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue13511] Specifying multiple lib and include directories on linux
Ray rpq...@hotmail.com added the comment: Whether or not includedir and libdir are supposed to allow multiple packages is beyond me at this point so I'll change the topic to more reflect the problem I am having. More importantly (and possibly related to includedir and libdir) is the fact that python 2.7 does not allow specifying multiple lib and include directories in linux. Is there one way to do this that I overlooked? I included the bit about includedir, libdir, CFLAGS, and LDFLAGS in my original post to show what I tried. Is it a standard for CFLAGS AND LDFLAGS to accept multiple directories? I would think so. With the current python 2.7 and linux, that simply does not work. But it does for darwin platforms? From setup.py: if platform == 'darwin': # This should work on any unixy platform ;-) # If the user has bothered specifying additional -I and -L flags # in OPT and LDFLAGS we might as well use them here. -- title: Let ./configure accept multiple --includedir and --libdir options - Specifying multiple lib and include directories on linux versions: +Python 2.7 ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue13511 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

If you need this functionality - you will still do 'if exists ... rename' and the TOCTTOU race will affect you.

anatoly techtonik techto...@gmail.com added the comment: On Fri, Dec 23, 2011 at 10:35 PM, Antoine Pitrou rep...@bugs.python.orgwrote: os.rename(overwrite=False) by default will do less harm than the opposite, Disagreed. Fine. No arguments == no consensus. Then I believe that having a small chance of overwriting file just created at exactly the same moment on a POSIX is a small price to pay for function that does safety check before rename on a platform that doesn't have such functionality at all. Disagreed. If you need the functionality, it's *one* additional line of code. Not every trivial function deserves to be in the stdlib. As a Windows programmer I am quite surprised to read this thread with information that on Linux os.rename() overwrites files without questions, so as I Windows programmer I want os.rename() to stop that. I always guard my code against accidental rewrite by catching the exception. EAFP and all that stuff. But there is no way I can ask forgiveness when files are already overwritten. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue8828 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue8828] Atomic function to rename a file
R. David Murray rdmur...@bitdance.com added the comment: So maybe my warning idea isn't such a bad idea :) As a unix programmer, I was very surprised to read in this thread that Windows doesn't overwrite the file on rename. As a unix programmer, I don't check for errors on a rename, because I expect it to just work. I'd like the windows rename call to stop throwing errors if the file exists, it breaks my programs if they run on windows. (Actually, very few of my programs ever get run on Windows, but you get the idea.) Thus, the only possible course is to maintain backward compatibility, and allow the programmers who care to specify the desired behavior. Since one of the important aspects of 'rename' in unix programmers' minds is that it is atomic, a race condition is not acceptable, therefore overwrite=False is not an acceptable option for os.rename. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue8828 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue13657] IDLE doesn't support sys.ps1 and sys.ps2.
Roger Serwy roger.se...@gmail.com added the comment: This would make the IDLE shell interface more consistent with the original interpreter. Presently, the prompt is faked by showprompt in PyShell.py. It relies on sys from the IDLE gui process and not from the sys in the subprocess, so mimicking the changed prompt would require querying the subprocess for its sys.ps1 and sys.ps2. The enter_callback method will need modification to remove sys.ps2 from the text buffer before execution. Also, EditorWindow.py has code for handling sys.ps1 in smart_backspace_event and newline_and_indent_event. If anything, this shell-specific, prompt-handling code needs some refactoring as it should only be in PyShell.py, not in EditorWindow.py. Issue13039 is a result of prompt code side-effects in EditorWindow.py. -- nosy: +serwy ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue13657 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

Terry J. Reedy tjre...@udel.edu added the comment: 2.7 is closed to new features. This looks like it mignt be one. The 2.7 doc for tarfile.open says Return a TarFile object for the pathname name. Does the meaning of 'pathname' in 2.7 generally include unicode as well as str objects? (It is not in the Glossary.) The error does not occur under Python 3 (even with non-ascii characters), so it should be possible to create a tarfile with a unicode filename on Python 2.7.

So I would say that this is not a crash and not even a bug, but a particular choice of undefined behavior given infinite loop code. So we have no obligation to change it. I presume the change from 2.x is a side-effect of a change to improve something else. def recurse(): recurse() recurse() does print RuntimeError: maximum recursion depth exceeded but only after printing al o n gtraceback.

[issue13653] reorder set.intersection parameters for better performance
Terry J. Reedy tjre...@udel.edu added the comment:
Given that equality is not identify, order does matter, although in 3.2.2 the
results are the opposite of what one might expect.
a = set((1,2,3))
b = set((1.0, 3.0, 5.0))
print(ab, ba)
print(a.intersection(b), b.intersection(a))
a = b
print(a)
{1.0, 3.0} {1, 3}
{1.0, 3.0} {1, 3}
{1.0, 3.0}
In my view, a = b should remove the members of a that are not in b, rather
than deleting all and replacing some with equal members of b.
That glitch aside, remains and remains binary for exact control of order. The
doc should just say that intersection may re-order the intersection for
efficiency.

New submission from maniram maniram maniandra...@gmail.com: If you call help() a few times on some objects, due to help()'s output IDLE's Shell Window becomes very long and it becomes difficult to scroll through the window.

Ron Adam ron3...@gmail.com added the comment: Updated patch with suggested changes. It also has a cleaned up fast_block_end section. Concerning speed. What happens is (as Tim and Raymond have pointed out) that we can make some things a little faster, in exchange for other things being a little slower. You can play around with the order of the why cases in the fast_block_end section and see that effect. By using a switch instead of if-else's, that should result in more consistent balance between the block exit cases. The order I currently have gives a little more priority for exceptions and that seems to help a tiny bit with the ccbench scores. I think that is a better bench mark than the small micro tests like pybench does. The problem with pybench is, it doesn't test deeper nesting where these particular changes will have a greater effect. -- Added file: http://bugs.python.org/file24087/f_why2.diff ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue13607 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
