[issue23809] RFE: emit a warning when a module in a traceback shadows a stdlib module
Robert Collins added the comment: Implementation wise: this is not part of the generic rendering-of-tracebacks; I'd like to make the traceback new stuff be tastefully extensible - I'd be inclined to do this with a per-frame-callback on render (so we don't pay overhead on unrendered tb's) and a global variable that controls the default hooks loaded into the objects. That would: - allow folk using the raw API to control what hooks are at play - allow third-parties to install additional things globally, to influence code using the existing old tb apis - make testing of the warning specific code be very straight forward and isolated -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue23809 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue22117] Rewrite pytime.h to work on nanoseconds
STINNER Victor added the comment: I rewrite the implementation of this issue 2 or 3 times. At the end, I decided to rewrite it again with a more incremental approach: add the new API, use the new API, and then drop slowly the old API. I was used to rewrite the implementation multiple times to fix issues in the API and enhance the implementation. The new API now handles better rounding with more unit tests. The datetime module only uses the new API for the datetime.datetime() constructor. It's not used for datetime.datetime.fromtimestamp(), because _PyTime_t is limited to a range of [-292 years; 292 years]. The datetime module supports a much large range: year in range [1; ]. So some parts of the old API will survive for the datetime module. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue22117 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue23809] RFE: emit a warning when a module in a traceback shadows a stdlib module
New submission from Nick Coghlan: A colleague just ran into the issue where they created a json.py module in their local directory and broke a previously working program. I picked up on the mistake when I saw the following traceback snippet: Traceback (most recent call last): File stdin, line 1, in module File /usr/lib/python2.7/site-packages/praw/__init__.py, line 27, in module import json File json.py, line 1, in module r = requests.get(http://www.reddit.com/user/spilcm/about/.json;) However, actually making the connection required thinking Wait, why is the stdlib JSON module calling out to Reddit? followed immediately by Oh, that's not the stdlib json module. That connection would potentially be easier for new Python users to make if there was an inline notification printed after the traceback warning of the stdlib module shadowing. If nothing else, it would give them something specific to search for to lead them to a discussion of name shadowing and the problems that can arise when you name one of your local modules the same as a standard library module. Offering such a feature would necessarily rely on having a standard way of getting a programmatic list of the standard library modules available to the running interpreter version without actually loading them all, a question which is discussed further in https://stackoverflow.com/questions/6463918/how-can-i-get-a-list-of-all-the-python-standard-library-modules and https://github.com/jackmaney/python-stdlib-list Since the contents of the standard library for a given release is immutable, and we'd like to keep any such mechanism (if we decide to provide it) very simple so we can easily access it from the low level interpreter traceback machinery, my suggestion would be along the lines of: 1. Update the interpreter build process to emit a flat text file containing a complete list of fully qualified stdlib module names (including submodules), one name per line (this will be generated at build time, so it *won't* contain filenames, just the module names - however, it could theoretically be combined with importlib.util.find_spec to generate a PEP 376 style RECORD file for the non-builtin parts of the standard library at installation time) 2. Rather than exposing the underlying machinery to end users directly, instead expose a function in sysconfig to read that list of modules into memory via a read-only line based iterator. (There may be an internal API to allow access to the content without going through sysconfig) 3. Updating the two main traceback display mechanisms (the builtin traceback display and the traceback module) to check that list for potential conflicts after displaying a traceback (This idea could benefit from discussion on python-ideas and potentially even escalate into a full PEP, but I don't currently have the personal bandwidth available to pursue that course. Accordingly, I'm just filing the idea here in case someone else finds it intriguing and has more time available to pursue it) -- messages: 239543 nosy: georg.brandl, larry, ncoghlan, rbcollins priority: normal severity: normal status: open title: RFE: emit a warning when a module in a traceback shadows a stdlib module type: enhancement versions: Python 3.5 ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue23809 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue23809] RFE: emit a warning when a module in a traceback shadows a stdlib module
Nick Coghlan added the comment: I had an idea for a possible importlib.util API to support this capability: an ignore_entries=0 default arg to https://docs.python.org/dev/library/importlib.html#importlib.util.find_spec The new arg would say how many found entries to skip when looking for the module, defaulting to returning the first hit as it does now. The challenging part would be that all the implicit import system caching is currently built around the notion of there can be only one, so we'd likely want to introduce something like a new name shadowing cache that mapped (modname, ignored_entries) pairs to module specs (and was cleared by importlib.invalidate_caches() along with everything else). -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue23809 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue23602] Implement __format__ for Fraction
Tuomas Suutari added the comment: Thanks for the comments again! I fixed the format(F(4, 27), '.1f') - 0.2 issue Serhiy Storchaka reported. Fix for that was as simple as adding one to the precision the decimals are calculated in, but while adding test cases for that I realized two new things: (a) I don't want f specifier to mean infinite precision, but instead some predefined value. I chose 6. (b) How about rounding? I don't want the current decimal context to affect that, since it's not logical that formatting of Fractions depends on the decimal context. The rounding thing made things harder, since there was no way to pass decimal context for Decimal.__format__ without changing the local context -- at least with the C implementation; the Python implementation (_pydecimal) provided nicer API with optional context keyword argument. So I decided to unify the C and Py API's of Decimal.__format__ and add the keyword argument support to the C API too. This is done in this v4 of the patch. There's no docs for the added Decimal.__format__ kwargs, since I want some comments on that change first. -- Added file: http://bugs.python.org/file38728/issue23602v4.patch ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue23602 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

I was reproduce to issue on a buildbot and I got access to the buildbot. Using gdb, I saw that a process was stuck in _close_open_fds_safe(). The problem is that this function is called after fork() to run a child process. It's not safe to play with the GIL here. This bug is the regression which makes some buildbots to hang.

[issue23809] RFE: emit a warning when a module in a traceback shadows a stdlib module
Nick Coghlan added the comment: I proposed limiting it to stdlib names as that's the case where we see the most beginner confusion (experimenting with sockets in a file named socket.py, etc), and the one where we can generate a comprehensive list of known module names ahead of time (so in most cases we won't need to touch the filesystem to determine there's no shadowing happening once the list of stdlib modules has been pulled in to memory). Handling the general case means we have to instead rely on rescanning the import system at runtime. On the other hand, we're already doing something along those lines through linecache to handle retrieving source lines, and the import system itself already has caches everywhere (hence importlib.invalidate_caches()), so adding yet-another-cache to be able to check for module shadowing efficiently wouldn't be that big a deal. Adding Brett Eric to get some additional perspectives on the idea of doing checks for name shadowing through a new importlib.util API rather than a separate stdlib specific mechanism. -- nosy: +brett.cannon, eric.snow ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue23809 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue23529] Limit decompressed data when reading from LZMAFile and BZ2File
Martin Panter added the comment: Patch v9: * Incorporated _PaddedFile.rewind() into seek() for simplicity * Reverted to support fast-forwarding in non-seekable streams again * Factored common checks into _check_can_seek() * Documented “mtime” attribute and implemented it as a read-only decompression-only property Antoine highlighted the fact that BufferedReader.peek() does not guarantee how much data it returns, so I removed the code trying to return at least 100 bytes. I revisited merging the gzip read() loop with the others, but gave up again. I tried adding calls to _start_member() and _end_member(), with more “if” statements and flags to account for the different edge cases. But then I remembered the “needs_input” flag of LZMA and bzip versus the “unconsumed_tail” of zlib. Handling this would probably require another delegation to a new _decompress_chunk() method, at which point I think the whole read() method will probably just be a mess of hacks trying to marry the two not-quite-compatible implementations. So I think it is better to override read() with a gzip-specific implementation, unless someone wants to prove me wrong with their own patch :) -- Added file: http://bugs.python.org/file38733/LZMAFile-etc.v9.patch ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue23529 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

IMHO those should be supported as they are with floats and Decimals. The correct way to format Fraction as fixed-precision decimal is to use Fraction.__round__() or similar algorithm. The implementation can look like: f = self.__round__(prec) i = int(f) return '%d.%0*d' % (i, prec, abs(f - i) * 10**prec) Why this would be more correct than delegating the rounding (and formatting) to Decimal.__format__?

Stefan Behnel added the comment: But these parameters could also be partly delegated to normal string (not number) formatting, right? One of the advantages of not depending on Decimal is, well, to not depend on Decimal, which is a rather uncommon dependency when using Fractions in an application. I think it could avoid some more calculations to first multiply the nominator by 10**prec, then round(), int() and str() the result, and then split the string at -prec. BTW, if division with remainder wasn't (sadly) linear time, that would definitely be the most beautiful algorithm here. :) -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue23602 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue23804] SSLSocket.recv(0) receives up to 1024 bytes
New submission from Martin Panter: The documentation claims that SSL socket objects provide some of the same methods as plain socket objects, including recv(), and that the “bufsize” parameter specifies the maximum amount of data to be received. With ordinary sockets, socket.recv(0) always seems to return zero bytes (b), as expected. But not so with SSL sockets: import socket, ssl s = ssl.wrap_socket(socket.create_connection((localhost, 631))) s.sendall(bGET / HTTP/1.1\r\nHost: localhost\r\n\r\n) 35 len(s.recv(0)) 263 len(s.recv(0)) 1024 The call will hang or raise SSLWantReadError when no data is actually available. Looking at the code, the value of zero seems to be used as a placeholder for a default of 1024 in SSLObject.read(). Either the SSL module should be fixed to return no bytes (my preference), or the documentation needs to warn that the recv(0) is not supported, or does not work the same as for plain sockets. SSLSocket.read() might also be affected. -- components: Library (Lib) messages: 239483 nosy: vadmium priority: normal severity: normal status: open title: SSLSocket.recv(0) receives up to 1024 bytes type: behavior versions: Python 2.7, Python 3.4, Python 3.5 ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue23804 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue22941] IPv4Interface arithmetic changes subnet mask
Søren Løvborg added the comment:
As mentioned python-dev, I'm not entirely sold on raising an exception on
overflow.
To recap the mailing list discussion, there was general agreement that the
current behavior is a bug, suggesting that there's no need to go through the
depreciation process. There's been three proposals for correct behavior, though:
A) To simply ignore the subnet mask: 10.0.0.255/24 + 1 = 10.0.1.0/24
B) To wrap around inside the subnet: 10.0.0.255/24 + 1 = 10.0.0.0/24
C) To raise exception.
First, note what happens if we overflow an IPv4Address:
ipaddress.IPv4Address('255.255.255.255') + 1
Traceback (most recent call last):
...
ipaddress.AddressValueError: 4294967296 (= 2**32) is not permitted
as an IPv4 address
At least that suggests a type of exception to use in proposal C.
There was not much support for the idea of wrapping (B); for which I see three
reasons:
1) No identified use case where this effect would be desirable.
2) It's implicit rather than explicit: The addition operator usually does not
imply modular arithmetic.
3) It's inconsistent with IPv4Address, which doesn't wrap.
That leaves the question of raising an exception (C), or not (A).
Now, I used IPv4Interface + 1 to mean Give me the IP next to the current one
in the current subnet, knowing from the context that the address would be
valid and available.
host = ipaddress.IPv4Interface('10.0.0.2/24')
peer = host + 1
In this context, an exception makes a lot of sense, as it would certainly have
been an error if I'd overflowed the subnet.
However, I can also imagine situations in which overflowing would be valid and
expected, e.g. as a way to skip to the same IP in the next subnet:
ip = ipaddress.IPv4Interface('10.0.0.1/24')
ip + ip.network.num_addresses
IPv4Interface('10.0.1.1/24')
There's an additional issue with raising an exception, and that is that it
still won't catch the errors as intended. In my use case:
host = ipaddress.IPv4Interface('10.0.0.254/24')
peer = host + 1
This wouldn't overflow and not trigger an exception, but the resulting peer
address is still invalid (it's the subnet broadcast address, not a host
address).
As for consistency with IPv4Address, I can argue for either proposal:
A) An IPv4Interface behaves exactly like an IPv4Address, except that it also
has an associated subnet mask. (This is essentially how it's currently
documented).
C) Overflowing an IPv4Interface raises AddressValueError just like with
IPv4Address.
All in all, I'm in favor of keeping things simple and go with solution A, since
C prevents a reasonable use, and doesn't actually catch out of bounds errors
anyway. I'm open to being convinced otherwise, though.

[issue23602] Implement __format__ for Fraction
Wolfgang Maier added the comment: Initially, I also thought that this should be addressable with Fraction.__round__ or an optimized variation of it, but Tuomas is right that it gets complicated by the fact that you need to cope with the different format specifiers and not all of them fit the algorithm. In particular, scientific notation poses a problem because it may require a lot more precision in the calculation than the one finally used for formatting. Consider: float(round(Fraction(4, 27000), 6)) 0.000148 but format(4/27000, 'e') '1.481481e-04' Trying to deal with this in pure Python quickly slows your code (at least a few naive attempts of mine) unacceptably compared to Tuomas' patch. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue23602 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue23787] sum() function docstring lists arguments incorrectly
Valentine Sinitsyn added the comment: Seems like mentioning string was really a bad idea. They were only used as (poor) example, forget them if they are confusing in any way. In my understanding, any sequence in Python is iterable, bit not all iterables are sequences (correct me if I'm wrong). Then, the purpose of my suggestion is to explicitly say that sum() accepts iterables. In its current form, it seems like it doesn't, that's why I considered the docstring [subtly] wrong. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue23787 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue23801] cgi.FieldStorage has different (wrong?) behavior on Python3 than Python2
Donald Stufft added the comment: @Benjamin The reason I didn't do that to begin with, was the code currently checks if the first line is a bytes object or not in order to be able to raise an error if it's returning str instead of bytes. I didn't want to redo that check on every iteration, so I left the original part alone and then used the while loop to handle doing more if needed. Would you prefer the code written your way and either drop the bytes check or incur the cost of doing the type check on every line? -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue23801 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue2211] Cookie.Morsel interface needs update
R. David Murray added the comment: I made several changes to the patch. The whatsnew docs didn't format correctly: there's an extra space on all the lines after the first (a three space indent is apparently required there which I don't understand, but it is also our standard for docs). Also none of the links work, because in the whatsnew document (unlike in the doc page itself) you have to fully qualify the names (eg: ~http.cookies.Morsel to display 'Morsel' and link to the right place). The line about LegalChars was in the wrong section. I rewrote both as a single bullet item with working links. The 'update' and 'copy' methods were not documented. I added them and moved the relevant 'versionchanged' phrases under the newly documented methods. In addition, I decided that the deprecation for key, value, and coded_value would be clearer if phrased as : assignment to XXX; use set instead. A couple of other notes: while functionally it doesn't (currently) make any difference to Sphinx if you use :func: vs :meth:, :meth: is the correct one for all these cases. And you had an extra blank line after the versionchanged directive. I've uploaded the changeset I applied as a diff so that you can more easily see what I changed if you wish. -- Added file: http://bugs.python.org/file38729/http_cookies_morsel_deprecated_set_4.patch ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue2211 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
