[issue23756] Tighten definition of bytes-like objects
Serhiy Storchaka added the comment:
Totally agree. Current definition is too wide. Actually in different places the
term bytes-like object can imply different requirements.
* Supports buffer protocol. list isn't.
* Contiguous. memoryview()[::2] isn't.
* len() returns bytes size. array('I') isn't.
* Supported indexing (and slicing) of bytes. array('I') isn't.
* Indexing returns integers in the range 0-255. array('b') isn't.
* Supports concatenation. memoryview isn't.
* Supports common bytes and bytearray methods, such as find() or lower().
* A subclass of (bytes, bytearray).
* A subclass of bytes.
* A bytes itself.

[issue23759] urllib.parse: make coap:// known
New submission from chrysn: The CoAP protocol (RFC 7252) registers the new URI schemes coap and coaps. They adhere to the generic RFC3986 rules, and use netloc and relative URIs. Therefore, please add the 'coap' and 'coaps' schemes to the uses_relative and uses_netloc lists in urllib.parse. I'm not sure about uses_params; the CoAP protocol in itself does not do anything special with the ';' character in URIs, so probably it should not be included there. (But then again, neither does RFC2616 mention ; in the context of addresses, and it is included in uses_params). -- components: Library (Lib) messages: 239106 nosy: chrysn priority: normal severity: normal status: open title: urllib.parse: make coap:// known type: enhancement ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue23759 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue12319] [http.client] HTTPConnection.putrequest not support chunked Transfer-Encodings to send data
Martin Panter added the comment:
I left a few comments on Reitveld, mainly about the documentation and API
design.
However I understand Rolf specifically wanted chunked encoding to work with the
existing urlopen() framework, at least after constructing a separate opener
object. I think that should be practical with the existing HTTPConnection
implementation. Here is some pseudocode of how I might write a urlopen()
handler class, and an encoder class that should be usable for both clients and
servers:
class ChunkedHandler(...):
def http_request(...):
# Like AbstractHTTPHandler, but don’t force Content-Length
def default_open(...):
# Like AbstractHTTPHandler, but instead of calling h.request():
encoder = ChunkedEncoder(h.send)
h.putrequest(req.get_method(), req.selector)
for item in headers:
h.putheader(*item)
h.putheader(Transfer-Encoding, encoder.encoding)
h.endheaders()
shutil.copyfileobj(req.data, writer)
encoder.close()
class ChunkedEncoder(io.BufferedIOBase):
# Hook output() up to either http.client.HTTPConnection.send()
# or http.server.BaseHTTPRequestHandler.wfile.write()
encoding = chunked
def write(self, b):
self.output({:X}\r\n.format(len(b)).encode(ascii))
self.output(b)
self.output(b\r\n)
def close(self):
self.output(b0\r\n\r\n)

[issue23747] platform module exposes win32_ver function on posix systems
R. David Murray added the comment: It is a deliberate choice because the functions accept default values to be returned if the actual values cannot be determined, and because it is easier therefore to write cross-platform scripts if the functions do *not* raise an error when called on the wrong platform. There are other functions in the platform module to use to determine which platform you are on. Agreed that the fact that they work is currently documented only by implication for those familiar with our doc style (that is, there are no avaiability tags, implying they are available on all platforms).

It appears to be 90% fixed with this patch, but I believe there is still a

Could this be the correct addition to fix it?

But in Python 3.4 it was receive empty clipboard. If I prevent the script from the immediate exit, adding input() after clipboard_append(), I see that clipboard contains the correct Result. If I run script, switch to any other window and press Ctrl+V, I receive Result and Result remains in clipboard after script exits.

[issue23761] test_socket fails on Mac OSX 10.9.5
Carol Willing added the comment:
Thanks Ned and R. David. A few questions...
1. I've rerun the tests using:
One failure:
70 tests OK.
1 test failed:
test_socket
1 test altered the execution environment:
test_warnings
21 tests skipped:
test_curses test_dbm_gnu test_devpoll test_epoll test_gdb
test_lzma test_msilib test_ossaudiodev test_smtpnet
test_socketserver test_spwd test_startfile test_timeout test_tk
test_ttk_guionly test_urllib2net test_urllibnet test_winreg
test_winsound test_xmlrpc_net test_zipfile64
I noticed that many tests are skipped since Network is not enabled. Although
test_socket fails and is not skipped, it seems plausible that the failure in
test_socket should also be skipped when Network is disabled. Other test files
that are skipped have support.requires('network') in the beginning of the file.
Should test_socket.py have this as well?
2. I am rerunning the tests with the following command:
./python.exe -m test -uall
Tests dependent on 'Network' are now run. Three failures now:
3 tests failed:
test_curses test_nntplib test_socket
1 test altered the execution environment:
test_warnings
14 tests skipped:
test_dbm_gnu test_devpoll test_epoll test_gdb test_lzma
test_msilib test_ossaudiodev test_spwd test_startfile test_tk
test_ttk_guionly test_winreg test_winsound test_zipfile64
Detail:
nntplib.NNTPTemporaryError: 400 Permission denied: Closed service.
3. Is there a doc that outlines how to enable all dependencies needed to have
tests execute and not be skipped? Which is the preferred command for running
tests for Mac OSX?
I'm willing to keep chasing this down but need a little direction. Thanks.

[issue23766] json.dumps: solidus (/) should be escaped
Martin Panter added the comment:
According to that RFC section, the forward solidus is allowed to be in an
escape sequence, but it is also allowed unescaped:
“All Unicode characters may be placed within the quotation marks, except for
the characters that must be escaped: quotation mark, reverse solidus, and the
control characters (U+ through U+001F).”
. . .
unescaped = %x20-21 / %x23-5B / %x5D-10
In general, escaping the forward solidus is not needed, and is easier to read.
Apparently this escaping is a workaround for embedding JSON inside a HTML
script element, where the sequence “/” is not allowed, and HTML itself does
not allow escaping: http://www.w3.org/TR/html4/appendix/notes.html#h-B.3.2.
In that case, JSON like {markup: iitalic\/i} would be escaped, but most
cases still do not need escaping, such as {url: http://example.net/}.

[issue23550] Add to unicodedata a function to query the Quick_Check property for a character
Hammerite added the comment: I tried to add these responses within the code review section of the site, but I am unable to do so; when I click Send Message, I am taken to a page that consists of the text 500 Server Error and no other content. Therefore I am responding to the code review comments here. Ezio: The form comes before the chr because that is the order unicodedata.normalize() takes its arguments (though it takes a string rather than a single character). To write normalize(form, str) but quick_check(chr, form) would be quite inconsistent, I think, and would invite confusion. Agreed that a brief description of what the property is useful for would be good; I will make another patch that includes this. I will delete the space after the function name. I will also eliminate the column arrangement of the test code, although I think that this will make the code much less readable. Berker: Regarding whatsnew: Since I have your invitation to do so, I will. Regarding putting the normalisation form comparison into helper functions, I will follow your suggestion, and incorporate the improvement for normalize() as well. For the error message, this is the same error message that is given by unicodedata.normalize(). I could change it, but if I do, I think I should change it for normalize() at the same time. For two of your other points I would like to observe that the way I have done things is in mimicry of existing code that relates to the unicodedata module. Elsewhere in unicodedata.c multiline strings are continued using \, so I have done the same; in makeunicodedata.py the other arrays are not static so the new one is not static either. I could make these changes regardless, but the result would be inconsistency in the code. Or I could change these things everywhere in the relevant files, but this would mean I would be changing parts of the files that are not properly related to this issue. For the remaining stylistic points, I will make the changes you asked for. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue23550 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue23671] string.Template doesn't work with the self keyword argument
Terry J. Reedy added the comment:
This is a nice catch of a subtle bug and a nice fix. I verified that replacing
'self' with '*args' does not simply shift the problem from 'self' to 'args'.
class C:
def test(*args, **kwargs):
print(args, kwargs )
c = C()
c.test(1, args=2, kwargs=3, self=4)
(__main__.C object at 0x035FE128, 1) {'args': 2, 'kwargs': 3, 'self':
4}
While the * and ** names are, like parameter names, local names given in the
signature header, they are not counted as parameter names in the code object
.co_argcount or .co_kwonlyargcount attributes that are used along with
co_varnames in the name-argument matching process.

[issue23763] Chain exceptions in C
New submission from STINNER Victor: In Python 3, it becomes possible to chain two exceptions. It's one of the killer feature of Python 3, it helps debugging. In Python, exceptions are chained by default. Example: try: raise TypeError(old message) except TypeError: raise ValueError(new message) Output: Traceback (most recent call last): File x.py, line 2, in module raise TypeError(old message) TypeError: old message During handling of the above exception, another exception occurred: Traceback (most recent call last): File x.py, line 4, in module raise ValueError(new message) ValueError: new message In C, using the public PyErr_SetNone(), PyErr_Format(), PyErr_SetString(), ... functions, exceptions are *not* chained by default. You have to call explicitly the new private _PyErr_ChainExceptions() function introduced in Python 3.4. It is not trivial to use it: you have to call PyErr_Fetch() and check if an exception was already raised. In Python, the following examples are bad practice because they may hide important exceptions like MemoryError or KeyboardInterrupt: try: except: pass or try: except: raise ValueError(...) In C extensions, it's common to write such code, few functions check which exception was raised. Last months, I enhanced Python to detect exceptions ignored by mistake: I added assert(!PyErr_Occurred()) in many functions which can clear the current exception (ex: call PyErr_Clear()) or raise a new exception (ex: call PyErr_SetString(...)). The last step is the issue #23571 which now implements in release mode. For the next step, I propose to explicitly clear the current exception before raising a new exception. I don't know yet if it would be a good idea to modify PyErr_*() functions to automatically chain exceptions. -- messages: 239130 nosy: haypo priority: normal severity: normal status: open title: Chain exceptions in C ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue23763 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

STINNER Victor added the comment: For the next step, I propose to explicitly clear the current exception before raising a new exception. Attached pyerr_match_clear.patch implements this. It's only a work-in-progress. I prefer to get feedback on the patch before finishing it. The patch checks also which exception was raised using PyErr_ExceptionMatches() to avoid hiding import exceptions. Since my patch makes assumption on which exception is expected, it can change the behaviour of functions if I forgot a different exception which is also supposed to be replaced. Example: only catch ValueError and replace it with ValueError, whereas OverflowError must also be replaced with ValueError. -- Added file: http://bugs.python.org/file38667/pyerr_match_clear.patch ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue23763 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

Other functions using _PyErr_ChainExceptions(): - open() (io.open): if open() failed and f.close() raised an exception, chain the two exceptions - io.FileIO.close - io.TextIOWrapper.close - io.BufferedReader.close, io.BufferedWriter.close - _Py_CheckFunctionResult(), new function introduced in the issue #23571 -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue23763 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue23763] Chain exceptions in C
STINNER Victor added the comment:
pyerr_match_assertion.patch: Modify PyErr_ExceptionMatches() to raise an
exception if it is called with no exception set.
This patch can be used to ensure that pyerr_match_clear.patch doesn't introduce
regression.
Example:
-PyErr_Format(PyExc_TypeError,
- expected %s instance instead of %s,
- ((PyTypeObject *)type)-tp_name,
- Py_TYPE(value)-tp_name);
+
+if (PyErr_ExceptionMatches(PyExc_AttributeError)) {
+PyErr_Clear();
+PyErr_Format(PyExc_TypeError,
+ expected %s instance instead of %s,
+ ((PyTypeObject *)type)-tp_name,
+ Py_TYPE(value)-tp_name);
+}
This change is wrong is not exception is set, because PyErr_ExceptionMatches()
returns 0 if no exception was raised.

[issue22904] make profile-opt includes -fprofile* flags in _sysconfigdata CFLAGS
Bohuslav Slavek Kabrda added the comment: I'm also hitting an issue with test_sysconfig_module, but for a different reason: While building Python, I used make EXTRA_CFLAGS='some flags' and this makes test_sysconfig_module fail when I run make test or python -m test.regrtest. The problem is that EXTRA_CFLAGS, like profile-opt, is not in the Makefile, so _sysconfigdata has it stored from build - unlike distutils, which can't see the EXTRA_CFLAGS variable in the environment, thus resulting in failure. I'm not sure what's the proper solution here, but I think requiring people to run make test with precisely the same EXTRA_CFLAGS as make is not right (although it solves the issue).

[issue23763] Chain exceptions in C
STINNER Victor added the comment: pyerr_match_clear-2.patch: Updated patch, more complete (I also removed the assertions, I only added to debug). Since my patch makes assumption on which exception is expected, it can change the behaviour of functions if I forgot a different exception which is also supposed to be replaced. To reduce risks, we can just remove the new PyErr_ExceptionMatches() checks from the patch in a first time, and add them later, while being very careful. Calling PyErr_Clear() where exceptions must not be chained should be enough for a first step. -- Added file: http://bugs.python.org/file38677/pyerr_match_clear-2.patch ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue23763 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue23773] importlib does not properly remove frames when invoking external import hooks
New submission from Shiz:
When adding a custom module loader to sys.meta_path, importlib does not
properly remove its frames before invoking it. This results in a weird
traceback with importlib._bootstrap frames in if an error occurs during
load_module(), like such:
Traceback (most recent call last):

Attached is a patch against the current hg head that makes sure module loaders
are invoked through _call_with_frames_removed, so that the output becomes a lot
more readable:
Traceback (most recent call last):
File /Users/mark/Development/Projects/rave/rave/bootstrap/__init__.py, line
102, in bootstrap_game
__import__(MODULE_PACKAGE + '.' + mod.replace('.py', ''))

exec_module
super().exec_module(module)
File /.modules/opengl/core3/texture.py, line 8, in module
raise ValueError
ValueError
Ideally it would remove the calls /within/ the module loader itself too, but I
do not see an easy way to do this without changing the entire
_call_with_frames_removed semantics. This fixes most of the issues, though.

[issue23529] Limit decompressed data when reading from LZMAFile and BZ2File
Martin Panter added the comment: Wolfgang: If the patch here is too massive, perhaps you might like to review my patch at Issue 23528 first. :) It only fixes the “gzip” module, but is definitely simpler, so might have more chance of making it into 3.4 or 3.5 on time. === Changes introduced by patch v7 if anyone’s interested: https://bitbucket.org/vadmium/cpython/commits/b7c43f7. A few problems and behaviour changes are introduced: * GzipFile(filename=...).close() now relies on the garbage collector to close the file * EOFError(Compressed file ended before the end-of-stream marker was reached) repaced with “struct.error” exception in some cases, e.g. GzipFile(fileobj=BytesIO(gzip_data[:3])).read() * Premature EOF when stream ends in some cases, e.g. GzipFile(fileobj=BytesIO(empty_gzip + gzip_data)).read() However I think the general idea of inheriting the common reader class and overriding as necessary is sound. Just looks like the code got too messed around in the process. -- ___ 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

[issue23573] Avoid redundant allocations in str.find and like
STINNER Victor added the comment: It looks like fastsearch_memchr_1char() manipulate pointers for memory alignment. It's not necessary when looking for ASCII or Latin1 characters or for bytes. I propose to add a new fastsearch_memchr_1byte() function which would be used by bytes and bytearray, but also by str for ASCII and Latin1 strings. Are you interested to implement this idea Serhiy?

[issue23761] test_socket fails on Mac OSX 10.9.5
R. David Murray added the comment: There are always going to be tests that are skipped (ones that don't run on your platform). Most of test_socket should run even if all you have is localhost networking. The 'network' resource is designed to control access to *external* networking resources, and there is at least one specific test in test_socket that is protected by the resource. I always run the test suite using '-uall' myself, which enables all the resources except for the ones that take lots of memory or disk space. If you have built python from source/checkout, then you can run the test suite using: ./python.exe -m test -uall For investigating this failure, you should change the beginning of test_host_resolution from: for addr in ['0.1.1.~1', '1+.1.1.1', '::1q', '::1::2', '1:1:1:1:1:1:1:1:1']: self.assertRaises(OSError, socket.gethostbyname, addr) self.assertRaises(OSError, socket.gethostbyaddr, addr) to: for addr in ['0.1.1.~1', '1+.1.1.1', '::1q', '::1::2', '1:1:1:1:1:1:1:1:1']: for func in socket.gethostbyname, socket.gethostbyaddr: with self.subTest(addr=addr, func=func): self.assertRaises(OSError, func, addr) and report the results. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue23761 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue23743] Python crashes upon exit if importing g++ compiled mod after importing gcc compiled mod
matham added the comment: Well, we won't have to wait until interested solves it. After hours of debugging including compiling Python with VS2013 and looking at windows dump files, it seems that hard work pays off - sorry, I mean asking someone who knows the answer pays off :P. I asked on #mingw and it was suggested that I use mingw compiled with the SJLJ exception model. And indeed, using sjlj fixed this so that it does not crash anymore. It seems that mingw from mingw.org compiles with `--disable-sjlj-exceptions`, so one has to use mingw-w64's distribution which offers a sjlj build (for x86 and SEH for x64). I am wondering whether this information should be somewhere on the python website so that other people do not run into this issue. I'm not sure what the proper resolution is here so I'll live it open. Or maybe it should be open until the docs is updated to warn about this issue. Anyway, here's the pertinent parts of my #mingw chat: jon_y matham: I suggest going for SJLJ on 32bit jon_y SEH on 64bit jon_y avoid dw2 exception like the plague matham ok, the one I got from mingw-get says --disable-sjlj-exceptions --with-dwarf2 matham I'll try with sjlj matham from mingw-w64 matham jon_y, \o/\o/\o/\o/\o/\o/\o/ omg I'm so happy :D it looks like using sjlj fixed it jon_y matham: I mean --disable-sjlj-exceptions jon_y that is the C++ exception part jon_y dwarf2 as debug is fine jon_y --with-dwarf2 specifies the debug data format jon_y yeah, dw2 (when --disable-sjlj-exceptions is used) has lots of issues with python matham so the problem is when sjlj is disabled? matham I thought it was either/or with sjlj vs dw2 jon_y dw2 doesn't quite work right for windows jon_y it requires ALL dll code use the same shared libgcc dll jon_y failure to do so leads to random crashes, especially during program termination matham so why does mingw-get automatically do --disable-sjlj-exceptions? jon_y mingw.org only provides toolchain that uses dw2 exceptions jon_y this has been so ever since the 4.2.1 days jon_y (that was the first widely used Windows gcc 4.x version) jon_y matham: Cygwin had the same problem with python and their dw2 gcc recently jon_y but had some local patches done in to fix it -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue23743 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
