[issue19726] BaseProtocol is not an ABC

[Rhonda Parker]

Rhonda Parker added the comment:

T0 the people that manipulate universe of linux and unix based protocol should 
take in consideration when people skilled programming introduce downloads and 
install protocol to those unskilled in the like because it only creates a 
disassociation resulting in the majority to lean towards those who capitalize 
on the ignorant, creating products for the simple minded at the price of 
integrity and freedom to those who are swayed to such ends.  I just wish linux 
snobs would understand that so many are behind them.  They just have to open 
there arms and accept the ignorant... Just to explain my rant, I have 8 
different programs to install to make one program to work and all but python 
and one other are simple and currently inastalled.  All so my 2 year old can 
play games...

[R. David Murray]

R. David Murray added the comment:

See also issue 1674555, which aims to make test_site run without -S and 
everything else run with -S.  I think this issue is invalid, if I understand 
what you wrote correctly, since test_site *should* be reported as a skipped

Peter Otten added the comment:

I think the prompt can easily be treated differently because it is written to 
stderr. 
I don't see a difference for user input between input() and raw_input() on 
Linux with Python 2.7.2+ -- syntax-highlighting is applied to both.

[issue19839] bz2: regression wrt supporting files with trailing garbage after EOF

[Fabio Erculiani]

New submission from Fabio Erculiani:

In Sabayon Linux and Gentoo Linux, distro package metadata is appended at the 
end of bz2 files. Python 2.7, 3.1, 3.2 bz2 modules were handling the following 
attached file just fine, trailing garbage was simply ignored like the bunzip2 
utility does.

example test code:
f = bz2.BZ2File(path, mode="rb")
data = f.read(1024)
while data:
data = f.read(1024)
f.close()

The following code doesn't work with Python 3.3.3 anymore, at some point I 
receive the following exception (that comes from the bz2 module C code):

  File "/usr/lib64/python3.3/bz2.py", line 278, in read
return self._read_block(size)
  File "/usr/lib64/python3.3/bz2.py", line 239, in _read_block
while n > 0 and self._fill_buffer():
  File "/usr/lib64/python3.3/bz2.py", line 203, in _fill_buffer
self._buffer = self._decompressor.decompress(rawblock)
OSError: Invalid data stream

Please restore the compatibility with bz2 files with trailing garbage after EOF.

[issue19837] Wire protocol encoding for the JSON module

[Antoine Pitrou]

Antoine Pitrou added the comment:

Still, JSON itself is not a wire protocol; HTTP is. http://www.json.org states 
that "JSON is a text format" and the grammar description talks "UNICODE 
characters", not bytes. The ECMA spec states that "JSON text is a sequence of 
Unicode code points".

RFC 4627 is a bit more affirmative, though, and says that "JSON text SHALL be 
encoded in Unicode [sic]. The default encoding is UTF-8".

Related issues:
- issue #10976: json.loads() raises TypeError on bytes object
- issue #17909 (+ patch!): autodetecting JSON encoding

> The other simple solution would be to add b variants of the affected 
> APIs.

"dumpb" is not very pretty and can easily be misread as "dumb" :-)
"dump_bytes" looks better to me.

[issue19789] Improve wording of how to "undo" a call to logging.disable(lvl)

[Vinay Sajip]

Vinay Sajip added the comment:

It's not the docstring in the code, it's the actual documentation. I propose to 
change it so that the documentation for disable will read:

Provides an overriding level *lvl* for all loggers which takes precedence over 
the logger's own level. When the need arises to temporarily throttle logging 
output down across the whole application, this function can be useful. Its 
effect is to disable all logging calls of severity *lvl* and below, so that if 
you call it with a value of INFO, then all INFO and DEBUG events would be 
discarded, whereas those of severity WARNING and above would be processed 
according to the logger's effective level. If 
``logging.disable(logging.NOTSET)`` is called, it effectively removes this 
overriding level, so that logging output again depends on the effective levels 
of individual loggers.

Please confirm if this is still not clear enough, otherwise I will commit this 
in a day or two and close the issue.

[issue19840] The is no way to tell shutil.move to ignore metadata

[zodalahtathi]

New submission from zodalahtathi:

shutil.move sometimes fail when the underlining filesystem has limitations.

Here is a part of a stacktrace I'm getting :

  File "/usr/local/lib/python3.3/shutil.py", line 534, in move
copy2(src, real_dst)
  File "/usr/local/lib/python3.3/shutil.py", line 244, in copy2
copystat(src, dst, follow_symlinks=follow_symlinks)
  File "/usr/local/lib/python3.3/shutil.py", line 192, in copystat
lookup("chmod")(dst, mode, follow_symlinks=follow)
OSError: [Errno 38]

This behaviour is expected because shutil.move uses shutil.copy2 under the hood 
to copy file data and metadata.

However there is no way to tell shutil.move to use shutil.copy and to ignore 
metadata.

Maybe a new copy_metadata parameter (defaulting to True) or copy_function (like 
in shutil.copytree) would be an elegant solution?

[issue19841] ConfigParser PEP issues

[Ivailo Monev]

New submission from Ivailo Monev:

There are a few PEP violations like namespace clashes, the attached patch fixes 
some of them thus solving a problem for me where shared library build with 
Nuitka segmentation faults. The patch does not make the code backwards 
compatible with the vars and map arguments renames as there is no way to do 
that and maybe the new variable names, vvars and mmap are not appropriate but 
you can roll your own patch with the same idea.

Cheers!

[issue19842] selectors: refactor BaseSelector implementation

[Charles-François Natali]

New submission from Charles-François Natali:

Initially, BaseSelector was simply designed as the base implementation used by 
concrete ones like SelectSelector & Co.

Then BaseSelector evolved to be an ABC, but the problem is that it's really not 
usable as such: the register() and unregister() methods are not abstract, and 
instead store the fileobj -> key association in a private dictionary 
(_fd_to_key). Since this attribute is private, it cannot be used by third-party 
selectors implementation which might want to implement the ABC. Also, such 
implementations might not want to use a dictionay internally, and generally, 
inheritance should be avoided in this type of situations (since it breaks 
encapsulation).

In short, BaseSelector mixes up the type definition (ABC) and base 
implementation, which cannot be reused by subclasses anyway.

The attached patch cleans things up by making 
BaseSelector.{register,unregister,get_map} methods abstract (raising 
NotImplementedError by default).
Together with select(), those methods are the bare minimum that a conform 
selector implementation should provide.
get_key() still has a default implementation (atop get_map()), and so does 
modify() (atop register()/unregister()).

The concrete base implementation (on top of which are built SelectSelector & 
friends) is moved in a private _BaseSelectorImpl.

I think that's a cleaner design.

The only problem is that it makes some methods abstract, so I had to update 
test_telnetlib and asyncio/test_utils because they are implementing 
BaseSelector for mock tests.

BTW, is there a consensus on ABC names? Like AbstractSelector vs BaseSelector?

[issue10976] json.loads() raises TypeError on bytes object

[Nick Coghlan]

Nick Coghlan added the comment:

Issue 19837 is the complementary problem on the serialisation side - users 
migrating from Python 2 are accustomed to being able to use the json module 
directly as a wire protocol module, but the strict Python 3 interpretation as a 
text transform means that isn't possible - you have to apply the text encoding 
step separately.

What appears to have happened is that the way JSON is used in practice has 
diverged from JSON as a formal spec.

Formal spec (this is what the Py3k JSON module implements, and Py2 implements 
with ensure_ascii=False): JSON is a Unicode text transform, which may 
optionally be serialised as UTF-8, UTF-16 or UTF-32.

Practice (what the Py2 JSON module implements with ensure_ascii=True, and what 
is covered in RFC 4627): JSON is a UTF-8 encoded wire protocol

So now we're left with the options:

- try to tweak the existing json APIs to handle both the str<->str and 
str<->bytes use cases (ugly)
- add new APIs within the existing json module
- add a new "jsonb" module, which dumps to UTF-8 encoded bytes, and reads from 
UTF-8, UTF-16 or UTF-32 encoded bytes in accordance with RFC 4627 (but being 
more tolerant in terms of what is allowed at the top level)

I'm currently leaning towards the "jsonb" module option, and deprecating the 
"encoding" argument in the pure text version. It's not pretty, but I think it's 
better than the alternatives.

[issue19837] Wire protocol encoding for the JSON module

[Nick Coghlan]

Nick Coghlan added the comment:

Not sure yet if we should merge the two issues, although they're the 
serialisation and deserialisation sides of the same problem.

Haskell seems to have gone with the approach of a separate "jsonb" API for the 
case where you want the wire protocol behaviour, such a solution may work for 
us as well.

[Charles-François Natali]

Charles-François Natali added the comment:

> I'm wondering, is there a reason we made BaseSelector a public API?

The idead was to have an ABC so that users can implement their own
selector, and pass it to e.g. asyncio or anything alse expecting a
selector.
Other than that, the only use is as a documentation (i.e. to show
which methods are supported by all selectors implementations).

The problem for documentation use is that we're christening it as an
official API, and thus it becomes more difficult to refactor the
inheritance hierarchy.

Hmmm... Well I guess your proposal makes sense :-) Aka. having a
documented ABC, and then a private base implementation.

Otherwise, you can also document the methods without saying precisely to
which class they belong, which I started doing on asyncio, but
apparently it confuses some people.

[issue19843] Wait for multiple sub-processes to terminate

[Giampaolo Rodola']

New submission from Giampaolo Rodola':

I recently implemented this in psutil and thought it would have been a nice 
addition for subprocess module as well:
https://code.google.com/p/psutil/issues/detail?id=440

Patch in attachment introduces a new subprocess.wait_procs() utility function 
which waits for multiple processes (Popen instances) to terminate.
The use case this covers is quote common: send SIGTERM to a list of processes, 
wait for them to terminate, send SIGKILL as last resort:


>>> def on_terminate(proc):
... print("process {} terminated".format(proc))
...
>>> for p in procs:
...p.terminate()
...
>>> gone, still_alive = wait_procs(procs, timeout=3, callback=on_terminate)
>>> for p in still_alive:
... p.kill()


Are we still in time for Python 3.4?

os.path.split(os.path.abspath(file))[0]
returns

and
os.path.split(os.path.abspath(file))[1]
returns
'Amy Winehouse - Back To Black (2006)\x01 - Rehab.ogg'

Either you have to quote \ with \\ or you have to use a raw string. Withouth a

>>> import ntpath
>>> fname = r"C:\progs\python\test\target\Amy Winehouse\Amy Winehouse - Back To

>>> ntpath.split(fname)
('C:\\progs\\python\\test\\target\\Amy Winehouse\\Amy Winehouse - Back To Black

[issue19808] IDLE applies syntax highlighting to user input in its shell

[Terry J. Reedy]

Terry J. Reedy added the comment:

On a freshly booted machine, I retried 2.7.6/Windows/raw_input() 'for all the' 
and indeed I now see 'for' and 'all' colored.

The colorizing is done char by char. 'fo' is black, 'for' turns orange, 'forr' 
turns black again. Similarly, 'al' is black, 'all is purple, and 'allo' is 
black again. It is not a critical bug, but certainly annoying, especially to a 
new user.

For editor windows, colorizing is only done for .py(wo) files. I do not know 
how the colorizing is switched on after the file name is checked. The shell 
window is an editor window. It should switch to .py mode after printing >>> and 
back to .txt mode when \n or \n\n is entered to complete a statement. I believe 
the edit will be in pyshell.py

I expect the prompt and echoed input are both written to stdout by the user 
process. Neither are errors and both are colored blue. Warnings and exception 
tracebacks on stderr are red. Both come into the idle process via the socket 
connection, which is different from the idle process stdin connected to the 
keyboard.

[issue17397] ttk::themes missing from ttk.py

[Terry J. Reedy]

Terry J. Reedy added the comment:

As a non-tcl/tk user except via tkinter, I am not convinced that we should add 
a near-duplicate function. The *Python* doc for ttk.Style.theme_names says 
"Returns a list of all known themes."  If it does not do that, which it seems 
not to, it should be changed (whether the change is called a fix or 
enhancement).

>From the referenced Epler post, the situation seems more complicated on the 
>ttk side in that ttk has two similar functions: 'style theme_names', which 
>only reports 'loaded' names, and 'themes' which reports 'loaded and 
>available', though 'available' seems vague and dependent on strange package 
>calls. For Python, a parameter for one function would suffice to restrict or 
>augment the list returned, if indeed the option is needed.

Are 'unloaded but available' themes really available to use? Does 
Style.theme_use(available_name) work? If so, it seems to me that available_name 
should be reported by theme_names. If not, what is the use of knowing it?

Most any patch will need a doc patch.

[issue19846] print() and write() are relying on sys.getfilesystemencoding() instead of sys.getdefaultencoding()

[Sworddragon]

New submission from Sworddragon:

It seems that print() and write() (and maybe other of such I/O functions) are 
relying on sys.getfilesystemencoding(). But these functions are not operating 
with filenames but with their content. In the attachments is an example script 
which demonstrates this problem. Here is what I get:

sworddragon@ubuntu:~/tmp$ echo $LANG
de_DE.UTF-8
sworddragon@ubuntu:~/tmp$ python3 test.py
sys.getdefaultencoding(): utf-8
sys.getfilesystemencoding(): utf-8
ä
sworddragon@ubuntu:~/tmp$ LANG=C
sworddragon@ubuntu:~/tmp$ python3 test.py
sys.getdefaultencoding(): utf-8
sys.getfilesystemencoding(): ascii
Traceback (most recent call last):
  File "test.py", line 4, in 
print('\xe4')
UnicodeEncodeError: 'ascii' codec can't encode character '\xe4' in position 0: 
ordinal not in range(128)

[issue19846] print() and write() are relying on sys.getfilesystemencoding() instead of sys.getdefaultencoding()

[R. David Murray]

R. David Murray added the comment:

Victor can correct me if I'm wrong, but I believe that stdin/stdout/stderr all 
use the filesystem encoding because filenames are the most likely source of 
non-ascii characters on those streams.  (Not a perfect solution, but the best 
we can do.)
