[issue46739] dataclasses __eq__ isn't logical
Craig Coleman added the comment: >From https://docs.python.org/3/reference/datamodel.html#object.__hash__ User-defined classes have __eq__() and __hash__() methods by default; with them, all objects compare unequal (except with themselves) and x.__hash__() returns an appropriate value such that x == y implies both that x is y and hash(x) == hash(y). It doesn't work like that for tuples, NamedTuples nor dataclasses because their behaviour isn't expected to be a "user-defined class". -- ___ Python tracker <https://bugs.python.org/issue46739> ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue46739] dataclasses __eq__ isn't logical
Craig Coleman added the comment: Seems I learned a python lesson today. I've put myself back in python school and done some reading on a) the code behind dataclasses, b) PEP 557 and c) the doc'n for __eq__. After all the reading I've realised this I'd been making some assumptions about how __eq__ works which have now been corrected.

[issue6090] zipfile: Bad error message when zipping a file with timestamp before 1980
Craig McQueen added the comment: One ongoing weakness I see with this situation is that it's difficult to code a suitable work-around if a user wants to zip files that have a date < 1980 (e.g. to zip it with a datestamp of 1-Jan-1980). https://stackoverflow.com/q/45703747/60075 I am trying to create a zip file with Python 3.5.2 zipfile, on Linux. Some of the files I'm trying to add have timestamps of 1-Jan-1970 (embedded system without a real-time clock module). So zipfile gives an exception: ValueError: ZIP does not support timestamps before 1980 My goal then is to implement a work-around to add these files to the zip file with a timestamp of 1-Jan-1980. However, I am finding it difficult to find a suitable work-around. At first I thought I can do this: def zinfo_from_file(fullname, arcname): st = os.stat(fullname) mtime = time.localtime(st.st_mtime) date_time = mtime[0:6] if date_time[0] < 1980: date_time = (1980, 1, 1, 0, 0, 0) zinfo = zipfile.ZipInfo(arcname, date_time) return zinfo ... zinfo = zinfo_from_file(fullname, arcname) chunksize=512 with open(fullname, 'rb') as src, myzipfile.open(zinfo, 'w') as dest: while True: data = src.read(chunksize) if not data: break dest.write(data) ... However, it turns out that myzipfile.open(zinfo, 'w') is not supported until Python 3.6. (I'm using Yocto to build embedded Linux, which currently only supports Python 3.5.x.) I guess I could try doing myzipfile.writestr(...), although then it appears that I have to load the entire file data into memory. -- nosy: +cmcqueen1975 ___ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue6090> ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue24502] OS X installer provides flat sub-packages with no version numbers
Shea Craig added the comment: For what it's worth, I manage a lot of Macs and know a lot of people in similar roles at major enterprises. We greatly prefer installer packages for automated installation, and end up having to repackage installer apps routinely for products that don't use that mechanism. If it's not an app that can be dropped into the Applications folder, Apple installer packages really are the best format for enterprise deployment. >From the development side I'm not familiar enough with the advantages of >trying to use a metapackage to bundle the contained packages, but I can say >that the version numbers all being 0 causes me to have to do some extra work >to ensure upgrades can be compared against what's already installed.

Craig Holmquist added the comment: Can you point me toward any documentation on the additional tags you want to support?

(For comparison, the junction and symbolic link tags yield 10K+ results each.) Junctions are created with each user's home directory so they exist on every Windows system, even if the user never explicitly creates them.

[issue23407] os.walk always follows Windows junctions
Craig Holmquist added the comment: The attached patch changes _Py_attribute_data_to_stat to set S_IFLNK for both symlinks and junctions, and changes win_readlink to return the target path for junctions (IO_REPARSE_TAG_MOUNT_POINT) as well as symlinks. I'm not sure what to do as far as adding a test--either Python needs a way to create junctions or the test needs to rely on the ones Windows creates by default. Incidentally, the existing win_readlink doesn't always work correctly with symbolic links, either (this is from 3.5.2): >>> import os >>> os.readlink(r'C:\Users\All Users') '\x00\x00f\x00\u0201\x00\x02\x00\x00\x00f\x00\x00\x00' The problem is that PrintNameOffset is an offset in bytes, so it needs to be divided by sizeof(WCHAR) if you're going to add it to a WCHAR pointer (https://msdn.microsoft.com/en-us/library/windows/hardware/ff552012(v=vs.85).aspx). Some links still seem to work correctly because PrintNameOffset is 0.

[issue24049] Remove unused code in symtable.c and fix docs for import * checking
New submission from Nick Craig-Wood:
Here is a patch to remove some unused code in `symtable.c`
In Python3 `from x import *` was banned from use in functions completely.
This is detected by `symtable_visit_alias`
if (st-st_cur-ste_type != ModuleBlock) {
int lineno = st-st_cur-ste_lineno;
int col_offset = st-st_cur-ste_col_offset;
PyErr_SetString(PyExc_SyntaxError, IMPORT_STAR_WARNING);
However in `check_unoptimized` it checks for `import *` being used in a nested
function etc. This is the python2 behaviour which wasn't removed at the time
the new python3 behaviour was added.
According to my analysis and tests it is now impossible for `check_unoptimized`
to raise an error, since only valid uses of `import *` are left at the point it
is called.
I propose to remove that function entirely, its call, and fix some stray
documentation in this patch.

[issue23779] imaplib authenticate raises TypeError if authenticator tries to abort
New submission from Craig Holmquist:
If the authenticator object passed to the IMAP authenticate method tries to
abort the handshake by returning None, TypeError is raised instead of sending
the * line to the server.
import imaplib
imap = imaplib.IMAP4_SSL('imap.gmail.com')
imap.authenticate(b'PLAIN', lambda x: None)
Traceback (most recent call last):

File C:\Python34\lib\ssl.py, line 684, in send
v = self._sslobj.write(data)
TypeError: 'str' does not support the buffer interface
The problem is that _Authenticator.process returns a string instead of bytes in
this case.

[issue23486] Enum comparisons are 20x slower than comparing equivalent ints
New submission from Craig Holmquist: Running the attached test script: $ time python test.py enum real0m6.546s user0m6.530s sys 0m0.007s $ time python test.py int real0m0.384s user0m0.377s sys 0m0.000s I encountered this with a script that yielded a sequence of objects (potentially a few hundred thousand of them) and categorized them with instances of an Enum subclass.

Re: inheriting a large python code base
Look at the algorithms and see if there are faster ways. Great advice with the comments of writing test cases, getting into version control, taking passes through the code with tools, understanding what is slow and why it is considered slow. Then you should invest the time to understand the internal logic and the algorithms. Understand the performance O(N log N), O(N^2), O(2^N). See if there are better algorithms that should be used - is there an O(N). Implement that algorithm, test, then compare performance. Finally optimize the coding constructs. Depending on how long your program takes (a few milli-secs, a few secs, a few hours, a few days), optimized coding constructs may make no measurable difference. Finding better algorithms will. But a better algorithm changing code from 2 milli-secs to 1 milli-sec is only useful in specific environments - so it may not be worth your effort. Understand the performance of the code and the environment it is executed in. That is how I have gone about it type of work. -- https://mail.python.org/mailman/listinfo/python-list

[issue16487] Allow ssl certificates to be specified from memory rather than files.
Brandon Craig Rhodes added the comment: Kristján, you are certainly correct that a single-argument that can be either a filename or a cert is inappropriate; we should not be peeking inside of strings to guess what they contain. And I think you also have a good point about Pythonic-ness when it comes to polymorphism; routines that are sensitive to object type have been going more and more out of style for the past twenty years, and for good reason. But, having ceded those points, I still think string-or-file-like-object is the correct approach here, simply because it is the overwhelming approach of the Standard Library; everyone is used to it, and will already know the ropes of that approach; and it prevents noisying up the interface with redundant arguments. Were we doing this over again, we would simply not allow a filename at all, and let the user open the file if they needed to. But since a filename is allowed, it feels like the Official Standard Library Approach to also allow a file-like object. Some examples: zipfile.ZipFile: Open a ZIP file, where file can be either a path to a file (a string) or a file-like object. http://docs.python.org/2/library/zipfile#zipfile.ZipFile binhex.hexbin: Decode a binhex file input. input may be a filename or a file-like object supporting read() and close() methods. http://docs.python.org/release/2.7.5/library/binhex.html#binhex.hexbin xml.dom.minidom.parse: filename_or_file may be either a file name, or a file-like object. http://docs.python.org/2/library/xml.dom.minidom.html#xml.dom.minidom.parse mailbox.Mailbox.add: Parameter message may be a Message instance, an email.message.Message instance, a string, or a file-like object (which should be open in text mode). http://docs.python.org/2/library/mailbox.html#mailbox.Mailbox.add pickletools.dis: pickle can be a string or a file-like object. http://docs.python.org/2/library/pickletools.html#pickletools.dis I suggest that these precedents, along with others that I believe we could find with a more exhaustive search of the Standard Library, are sufficient to suggest that in this case the least-surprise approach is a single argument that's either a filename or file-like object. I would suggest reviewing quickly the code for the above examples and following their example for how to distinguish most cleanly between a filename and file-like object; I wonder if they call any common code to get the contents out, or each do it completely by themselves? :) Thanks again for wanting to add this to the SSL module, it will be a *great* addition that solves an important use case! -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue16487 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue16487] Allow ssl certificates to be specified from memory rather than files.
Brandon Craig Rhodes added the comment: Kristján, your patch is a wonderful idea—I am about to commit production code that will have to create tens of thousands of temporary files during operation, one file each time SSL is started up on a socket, which could be avoided if something like this patch were applied. I had always assumed that it was simply a limitation of the underlying SSL library! An interface that takes a filename like this, instead of a live file-like object, seems so un-Pythonic that I assumed the only reason for it was a limitation in OpenSSL. Thank you very much for looking under the covers and discovering that this was not the case! I do, though, feel a slight twinge when we add Even More Parameters to a Standard Library routine but in such a way that it cannot be used with an existing parameter — as here in your patch, where we gain a parameter like `certdata` that cannot be (should not be?) used at the same time as `certfile`. It seems redundant to have two names for the same parameter to the underlying library, and makes it look like the routine needs more information than it really does. Since my own instinct was to think, ten minutes ago, Maybe I can pass a StringIO, since it says it wants a fine!, I am very much in support of the idea of keeping only the existing parameters, but making them accept both strings (which, for compatibility, would continue to be interpreted as filenames) and file-like objects as arguments. I think this would have a great deal of symmetry with how other parts of the Standard Library work, while keeping this patch's central value of making it possible for those of us with cert-heavy code to avoid the creation of thousands of files a minute. Again, thank you VERY much for discovering that OpenSSL can do this, and I will try to provide whatever encouragement I can as you try to shepherd this past the other committers. -- nosy: +brandon-rhodes ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue16487 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue17855] Implement introspection of logger hierarchy
Brandon Craig Rhodes added the comment: Adding an entirely separate API for introspection strikes me as counter-productive — instead of merely having to maintain the logging API that you already maintain, you will additionally now have an entirely separate and second API that also has to be maintained forever. Reading back over the current logging documentation, it looks like the problem is that the documentation only includes verbs — the methods that can be invoked — but not adjectives: the attributes that are attached to each logger, handler, and filter. This is contrary to modern Python APIs, which typically document their attributes and offer direct access to them; within the Standard Library, cf the threading.Thread object for one that has done a good job of moving into the modern world with directly-accessible attributes. So my guess would be that you should discard the idea of a separate introspection API, and simply document that attributes of each logger, handler, and filter that today are already perfectly introspectable. Check out the logging_tree code if you want to make sure that you are “promoting” into document-hood all of the attributes that I needed in order to do my introspecting there. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue17855 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue13477] tarfile module should have a command line
Brandon Craig Rhodes added the comment: Larry Hastings rep...@bugs.python.org writes: Huh. tar *can* infer it from the data itself. On the other hand, it chooses explicitly not to. I guess tar knows explicit is better than implicit too ;-) I am told that the refusal of tar to introspect the data is because: (a) Tar runs gunzip -c (for example) as an external program; it does not actually compile against libz. (b) Streams in UNIX cannot be rewound. Tar cannot look at the first block of an input pipe and then put the block back so that the same input can be fed directly to gunzip as its input. (c) Given (a) and (b), tar could only support data introspection of input from a pipe if it were willing to be a pass-through that, after reading and introspecting the first block, then fired up gunzip and sent ALL of the blocks through. Which would require multiprocessing, threading, or async I/O so that tar could both read and write, which would make tar more complicated. (d) Therefore, tar refuses to even look. Since Python does bundle compression in its standard library, it can quite trivially step forward and actually do the data introspection that tar insists on not doing; the first few bytes of a tar archive are quite demonstrably different from the first bytes of a gzip stream, if I recall. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue13477 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue17370] PEP should not if it has been superseded
New submission from Brandon Craig Rhodes: A friend (@theomn on Twitter) was just working off of PEP-333 when I mentioned to him that PEP-, and he had never heard of it, and he expressed the wish that PEPs would have a banner or something at the top if there is a more recent version of them. I think his idea is great, and is like the feature of PyPI where if Google lands you on an old version of a package then it is careful to tell you up at the top that a more recent version is available. This could extend to all sorts of cross-references that we should maintain: some PEPs have been superseded; others have more recent supplements that people should read as well (think of the relationship between packaging PEPs); PEPs that did not wind up being implemented have cousins who were; and so forth. Is this something that needs to wait until the New Python Web Site appears, and that would be meta-markup somehow maintained along with the PEP texts themselves? Or should there be a “Related PEPs” paragraph that we open at the top of each relevant PEP and just include the cross-links as raw updates to the PEP's own restructured text? I'm open to a simple implementation here, so long as we can provide more “community context” when people land on a PEP. -- assignee: docs@python components: Documentation messages: 183625 nosy: brandon-rhodes, docs@python priority: normal severity: normal status: open title: PEP should not if it has been superseded ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue17370 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue14550] os.path.abspath() returns physical path, not logical path.
New submission from Craig Sawyer csaw...@yumaed.org:
we have os.path.abspath() and os.path.realpath(). the difference according to
the documentation is realpath() returns the physical path (i.e. no symlinks in
the path). while abspath() uses getcwd() but because of POSIX.1-2008 (IEEE Std
1003.1-2008) says os.getcwd() returns without symbolic links as well, so
os.path.abspath() == os.path.realpath() near as I can tell.
I think os.path.abspath() should return a logical path(i.e. one with symlinks).
The only solution I know of is to getenv('PWD') except that is not guaranteed
to be around in POSIX (some BSD's don't offer PWD I understand). The other
option is to ask /bin/pwd which is part of the POSIX standard.
Anyways, I couldn't find a previous bug around this issue, but I think there
should be a way in the standard library to get a logical path, as well as a
realpath().

[issue14550] os.path.abspath() returns physical path, not logical path.
Craig Sawyer csaw...@yumaed.org added the comment: Antoine, I see your point about getcwd() not having symlinks, doesn't mean any path outside of getcwd() might have symlinks, and I agree this is true. I apologize. As for which one to choose, it should choose based on PWD (i.e. the current working directory's parent directories). I'd love to see something like os.path.abspath(path, logical=True) which would use PWD instead of getcwd() to get the current working directories path. i.e. symlinks are honored within the current path. From a language perspective this probably means needing os.getpwd() or something similar, that would return the pwd information. I know pwd isn't always guaranteed to be around, so the failsafe should be to return getcwd() in that case, just like os.path.abspath() does now. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue14550 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

Re: alternative to with statement?
It is a bit non-normal. but I think this is a good use case as I want to create a very simple-to-use system for non-python experts to safely wrap their CLI programs in a caching architecture... that's why I lament the inability to not use the more streamlined 'with' syntax– abusing the for loop might just be confusing. The with statement is also a good fit because the caching strategy does have to atomically acquire, create and release the appropriate locks. With this statement the cached CLI wrappers can be called from simultaneously from different scripts and still coordinate their activity, by waiting for each other to finish, and reusing the cached results, etc. On Feb 28, 2012, at 1:04 PM, Craig Yoshioka wrote: I see that there was previously a PEP to allow the with statement to skip the enclosing block... this was shot down, and I'm trying to think of the most elegant alternative.

[issue11561] coverage of Python regrtest cannot see initial import of libs
Brandon Craig Rhodes bran...@rhodesmill.org added the comment: Brett, yes, you are welcome to close this issue — Ned quite handily convinced me that coverage code belongs in the coverage distribution, not languishing about in the CPython source tree. That solution also quite beautifully solves the copyright problem. So I happily withdraw my request for this feature. Nick, Brett is working on exactly the sort of devguide improvement that you suggest — not least because the devguide will now need to instruct people in how to build coverage so that its C-accelerated tracer is available, which Ned's own patch to coverage to cover stdlib tracing uses instead of the Python tracer that I cut-and-pasted into this patch. Finally, it would be wonderful to have a more formal mechanism for boot-time interventions. I have mentioned before my wish that Python's first action be to open() the executable, check its tail to see if it's a valid zipfile, and if so to try loading and running startup.py from that zipfile. Among other things, that would allow single-file distribution of pure-Python applications without the py2exe/py2app mess that prevails in the projects I work with today. But since the whole issue of grabbing control at boot time raises hackles (why would you want to do that!?), and I needed something working immediately during the PyCon sprint, I elected to simply adopt encodings.py as my way in. It works great, and coverage can evolve to an even better mechanism as soon as one becomes available, should anyone want to take the bootup option and run with it. One final thought: should PyPy etc also implement the same boot protocol, should one be invented, so that all mainline interpreters can be instrumented the same way? -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue11561 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

Brandon Craig Rhodes bran...@rhodesmill.org added the comment: Éric, the Makefile in Python trunk seems to include Objects/complexobject.o in the build unilaterally without any way to turn it off. What is leading you to believe that Python 3 can conditionally turn the complex type off during a build? I do not understand your question about Unicode — could you reference the line number in the patch file that is worrying you? -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue11572 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue11572] bring Lib/copy.py to 100% coverage
Brandon Craig Rhodes bran...@rhodesmill.org added the comment: Antoine, neither this issue, nor either version of my patch, was intended to assert that 100% test coverage indicates that a test of tests are complete. If you will point out where in the text this is implied, I will correct it.

[issue11572] bring Lib/copy.py to 100% coverage
New submission from Brandon Craig Rhodes bran...@rhodesmill.org: The attached patch will bring Lib/copy.py to 100% test coverage. A bug in coverage results in its only reporting 99% at the moment; see coverage issue #122 on bitbucket: https://bitbucket.org/ned/coveragepy/issue/122/for-else-always-reports-missing-branch This patch makes several minor improvements to copy: when doing getattr lookups with a default of None, it now uses an is comparison against None which is both faster and more correct; several special cases have been removed since Python 3 always has CodeType available; and an ancient obsolete test suite that had been appended to copy.py in ancient times has been removed. -- files: test_copy.patch keywords: patch messages: 131135 nosy: brandon-rhodes priority: normal severity: normal status: open title: bring Lib/copy.py to 100% coverage versions: Python 3.3 Added file: http://bugs.python.org/file21244/test_copy.patch ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue11572 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue502085] pickle problems (with Boost.Python)
Brandon Craig Rhodes bran...@rhodesmill.org added the comment: Benjamin, I would like some way to know when our tests achieve 100% coverage because otherwise I will keep coming back to this module to add more tests and have to re-discover code that is not CPython relevant. But for now I have removed the pragmas. The attached patch also changes assertIs() and assertIsNot(), and uses self.fail() instead of the exception inside of support.

[issue11572] bring Lib/copy.py to 100% coverage
Brandon Craig Rhodes bran...@rhodesmill.org added the comment: Benjamin, thanks for the pointers! The attached patch now uses assertIs() and assertIsNot(), and calls self.fail() instead of using the exception from support. In the future I would like some way to determine when test coverage is fully achieved, so that I do not come back to this module every few months and have to re-discover why it is not 100%. But for the moment I have indeed removed the pragmas, pending a better approach! -- Added file: http://bugs.python.org/file21246/test_copy2.patch ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue11572 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue11561] coverage of Python regrtest cannot see initial import of libs
New submission from Brandon Craig Rhodes bran...@rhodesmill.org: When running the Python regression tests in coverage, the initial outer level of interpreted code in several standard library modules shows as not having been covered by the tests, because they were imported during the Python boot process and were already loaded when the coverage command got control. -- messages: 131051 nosy: brandon-rhodes priority: normal severity: normal status: open title: coverage of Python regrtest cannot see initial import of libs ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue11561 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
