[issue35107] untokenize() fails on tokenize output when a newline is missing

[Ammar Askar]

Ammar Askar  added the comment:

Actually nevermind, disregard that, I was just testing it wrong. I think the 
simplest fix here is to add '#' to the list of characters here so we don't 
double insert newlines for comments: 
https://github.com/python/cpython/blob/b83d917fafd87e4130f9c7d5209ad2debc7219cd/Lib/tokenize.py#L659

And a test for round tripping a file ending with a comment but no newline will 
allow that particular branch to be tested.

I'll make a PR this week if no one else gets to it.

[issue35107] untokenize() fails on tokenize output when a newline is missing

[Gregory P. Smith]

Gregory P. Smith  added the comment:

Interesting!  I have a 3.6.2 sitting around and cannot reproduce that "x=1" 
behavior.

I don't know what the behavior _should_ be.  It just feels natural that 
untokenize should be able to round trip anything tokenize or generate_tokens 
emits without raising an exception.

I'm filing this as the "#" case came up within some existing code we had that 
happened to effectively test that particular round trip.

[issue35107] untokenize() fails on tokenize output when a newline is missing

[Ammar Askar]

Ammar Askar  added the comment:

fwiw I think there's more at play here than the newline change. This is the 
behavior I get on 3.6.5 (before the newline change is applied). # works as 
expected but check out this input:

>>> t.untokenize(tokenize.generate_tokens(io.StringIO('#').readline))
'#'
>>> t.untokenize(tokenize.generate_tokens(io.StringIO('x=1').readline))
Traceback (most recent call last):
  File "", line 1, in 
  File "D:\Python365\lib\tokenize.py", line 272, in untokenize
self.add_whitespace(start)
  File "D:\Python365\lib\tokenize.py", line 234, in add_whitespace
.format(row, col, self.prev_row, self.prev_col))
ValueError: start (1,0) precedes previous end (2,0)

[issue35107] untokenize() fails on tokenize output when a newline is missing

[Ammar Askar]

Ammar Askar  added the comment:

Looks like this is caused by this line here: 

https://github.com/python/cpython/blob/b83d917fafd87e4130f9c7d5209ad2debc7219cd/Lib/tokenize.py#L551-L558

which adds a newline token implicitly after comments. Since the input didn't 
terminate with a '\n', the code to add a newline at the end of input kicks in.

[issue35107] untokenize() fails on tokenize output when a newline is missing

[Gregory P. Smith]

New submission from Gregory P. Smith :

The behavior change introduced in 3.6.7 and 3.7.1 via 
https://bugs.python.org/issue33899 has further consequences:

```python
>>> tokenize.untokenize(tokenize.generate_tokens(io.StringIO('#').readline))
Traceback (most recent call last):
  File "", line 1, in 
  File ".../cpython/cpython-upstream/Lib/tokenize.py", line 332, in untokenize
out = ut.untokenize(iterable)
  File ".../cpython/cpython-upstream/Lib/tokenize.py", line 266, in untokenize
self.add_whitespace(start)
  File ".../cpython/cpython-upstream/Lib/tokenize.py", line 227, in 
add_whitespace
raise ValueError("start ({},{}) precedes previous end ({},{})"
ValueError: start (1,1) precedes previous end (2,0)
```

The same goes for using the documented tokenize API (`generate_tokens` is not 
documented):

```
tokenize.untokenize(tokenize.tokenize(io.BytesIO(b'#').readline))
...
ValueError: start (1,1) precedes previous end (2,0)

```

`untokenize()` is no longer able to work on output of `generate_tokens()` if 
the input to generate_tokens() did not end in a newline.

Today's workaround: Always append a newline if one is missing to the line that 
the readline callable passed to tokenize or generate_tokens returns.  Very 
annoying to implement.

[issue1154351] add get_current_dir_name() to os module

[Eryk Sun]

Eryk Sun  added the comment:

>  Windows getcwd() returns a path without resolved symbolic links

This provides consistency. If the working directory were resolved, then 
accessing "../file.ext" after chdir("C:/Temp/link") could be inconsistent with 
accessing "C:/Temp/link/../file.ext". This is a consequence of the way DOS 
paths are translated to native NT paths, which is implemented strictly as a 
string operation. Since "." and ".." are regular names in NT and not 
necessarily reserved (e.g. FAT32 allows creating a file named ".."), resolving 
a path POSIX style would require resolving it up to each ".." component. This 
would entail potentially making many system calls just to normalize a path 
before even getting to the intended operation.

> Use os.path.realpath() is you want to resolve symbolic links

In Windows, os.path.realpath is an alias for os.path.abspath, so it doesn't 
resolve links. Use os.path._getfinalpathname to resolve a file-system path. 
This returns a \\?\ local-device path, which I'd encourage retaining rather 
than automatically converting to a regular DOS path. The resulting path may be 
too long for a regular DOS path (if long paths aren't supported), or the final 
component of the path may conflict with DOS quirks such as reserved device 
names (e.g. "nul.txt") and ignoring trailing dots and spaces.

Funny, since it is the crash reports use of base64 encoding that led me to

[Antoine Pitrou]

Antoine Pitrou  added the comment:

First, it is quite uncommon to open a file in append mode.  Second, when you 
open in append mode, often you will gradually append (such as for a logfile), 
so a single method call isn't effective.

So I think this does not solve an important use case.

[issue23220] IDLE: Document how Shell displays user code output

[Terry J. Reedy]

Terry J. Reedy  added the comment:

While editing 'IDLE-console differences' (added in the patch above) for #35099, 
I decided that it should be renamed (to, say, 'Executing user code') and 
limited to the effect of executing user code in IDLE's execution process 
instead of a standard python process. Except for a intentional change to make 
developing tkinter code easier, such effects are unintended and possibly bad 
for developers using IDLE.

This issue is about one aspect of how IDLE's Shell, in the GUI process, 
displays strings and bytes sent from the execution process via sys.stdout and 
sys.stderr.  My previous revision of the title was wrong and my previous patch 
not directly relevant.

I will make a new patch to add a new section ('Displaying user code output'?) 
describing various aspects of how Shell displays std text output, starting with 
this one.  Most of the differences from various consoles and terminal are 
intentional and considered to be net positives.

While the handling of control characters is inherited from tk, Serhiy and I 
have claimed on other issues that displaying one glyph per character has 
advantages for development as well as disadvantages.  (Being about to display 
all but only the BMP subset of unicode is also inherited from tcl/tk.)

One of my unposted ideas is to add an option to the run menu to run edited code 
in the system console/terminal, detached from IDLE, the same as if the file 
were run from a command line or directory listing.  This would bypass both 
IDLE's execution and display effects.

Thx. One of the python bits I need to embrace.

Although - during my testing I saw that the null string "" was not being
accepted as None, but was accepted as "not cmd".

My reading error was taking None to mean a value was not initialized
while it seems to be None is a 'value' that is assigned, while ´not xxx'
can be either - never assigned or a null-length string.

This is the "ambiguity", at least for myself, that I feel I tracked down.

It is "unfortunate" if this breaks backward compatibility - IF the
backward compatibility has been based on an ambiguity. Or I again, miss
a fine-point of Python coding. Won´'t be the last time I expect.

Comments requested.

[issue33074] dbm corrupts index on macOS (_dbm module)

[Robert Xiao]

Robert Xiao  added the comment:

I just started a new project, thoughtlessly decided to use `shelve` to store 
data, and lost it all again thanks to this bug.

To reiterate: Although `gdbm` might fix this issue, it's not installed by 
default. But the issue is with `dbm`: Python is allowing me to insert elements 
into the database which exceed internal limits, causing the database to become 
silently corrupt upon retrieval. This is an unacceptable situation - a very 
normal, non-complex use of the standard library is causing data loss without 
any indication that the loss is occurring.

At the very least there should be a warning or error that the data inserted 
exceeds dbm's limits, and in an ideal world dbm would not fall over from 
inserting a few KB of data in a single row (but I understand that's a third 
party problem at that point).

Can't we just ship a dbm that is backed with a more robust engine, like a 
SQLite key-value table?

[issue35070] test_posix fails on macOS 10.14 Mojave

[Barry A. Warsaw]

Barry A. Warsaw  added the comment:

I've now updated my personal machine to Mojave and cannot reproduce the 
failure.  I'm going to chalk this one up to some weird corporate active 
directory or whatnot weirdness.  I'd still love to know why the code in Python 
works differently that the standalone C version, but I don't plan on spending 
much time on this issue unless new data comes in.

[issue33940] datetime.strptime have no directive to convert date values with Era and Time Zone name

[Alexander Belopolsky]

Alexander Belopolsky  added the comment:

Since the Python datetime only supports dates within 0001-01-01 through 
-12-31 range, it is not clear how we can meaningfully support the AD/BC era 
designation.

Looking at man strftime page on my Mac, I see that they use every upper an 
lower case letter as a valid format specifier, but they still not have a letter 
code for AD/BC.  In the "BUGS" section they humorousely complain that "There is 
no conversion specification for the phase of the moon" which makes me think 
that the moon phase designations are higher on some people agenda than the era 
designations.

[issue22377] %Z in strptime doesn't match EST and others

[Alexander Belopolsky]

Alexander Belopolsky  added the comment:

I think strptime should only accept %Z when it comes together with %z and not 
do any validation.

This is close to the current behavior.  %Z by itself is useless because even 
when it is accepted, the value is discarded:

>>> print(datetime.strptime('UTC', '%Z'))
1900-01-01 00:00:00

You have to use %z to get an aware datetime instance: 

>>> print(datetime.strptime('UTC+', '%Z%z'))
1900-01-01 00:00:00+00:00


The validation is already fairly lax:

>>> print(datetime.strptime('UTC+1234', '%Z%z'))
1900-01-01 00:00:00+12:34

I don't think this issue has anything to do with the availability of zoneinfo 
database.  Timezone abbreviations are often ambiguous and should only serve as 
a human-readable supplement to the UTC offset and cannot by itself be used as a 
TZ specification.

[issue35104] IDLE: On macOS, Command-M minimizes & opens "Open Module..."

[Ned Deily]

Ned Deily  added the comment:

AFAICT, the problem here is that there is a duplicate command accelerator 
assignment: IDLE assigns CMD-M to its Open Module command 
(https://github.com/python/cpython/blob/master/Lib/idlelib/config-keys.def#L205)
 but either Tk or the underlying macOS services it uses already use CMD-M to 
mean "minimize the front window to the Dock" 
(https://support.apple.com/en-us/HT201236).  You can see in the IDLE menu bar 
where CMD-M shows up in the Window menu stack (with Minimize) but not in the 
the File stack (where Open Module is).  Since CMD-M has a commonly used 
system-wide meaning, it would probably be best to change IDLE's Open Module to 
use something else.

[issue35104] IDLE: On macOS, Command-M minimizes & opens "Open Module..."

[Terry J. Reedy]

Terry J. Reedy  added the comment:

What I see in the .gif is that Open Module is open on top of Shell (not 
minimized, traffic lights gray) and that clicking Cancel closes Open Module and 
temporarily minimizes Shell, before it pops back up with traffic lights.  It is 
hard to imagine that how one opens Open Module changes its close behavior.

With 3.7.1rc1, with unreleased tk patches, Command-M immediately after opening 
IDLE (Shell) closes IDLE.  A window pops up offering to send a report to Apple, 
or to re-open.  'Re-open' does not work.  After opening another window, I see 
Shell minimize and pop back with the traffic lights gray.  Both Cancel and 
Escape have the effect in the gif.  Clicking OK with a valid module name does 
the same and opens the module.

In summary, using Command-M either crashes IDLE or causes the change in traffic 
lights to be accompanied by minimizing and restoring.

Kevin, another weird tkinter/tk Mac behavior.

[issue33826] enable discovery of class source code in IPython interactively defined classes

[Ivan Pozdeev]

Ivan Pozdeev  added the comment:

@Thomas Viehmann , as it's currently formulated, this is a duplicate because it 
strives to allow getting class source from past interactive input -- which, as 
I explained, is already possible without the patch and seems to be 
inappropriate for vanilla console anyway.

Your patch is rather a new class feature that provides a more robust link to 
its source, wherever it's located. If you reformulate your ticket to propose 
that instead, it will no longer be a duplicate. I'm not sure if the UI allows 
that, it may be better to create a new ticket.

[issue1154351] add get_current_dir_name() to os module

[STINNER Victor]

STINNER Victor  added the comment:

os.stat() has a following_symlinks parameter because there is lstat(). There is 
no lgetcwd(), only getcwd(). I dislike the parameter choice. Use 
os.path.realpath() is you want to resolve symbolic links.

[issue35105] Document that CPython accepts "invalid" identifiers

[STINNER Victor]

New submission from STINNER Victor :

The Python 3 language has a strict definition for an identifier:
https://docs.python.org/dev/reference/lexical_analysis.html#identifiers

... but in practice, it's possible to create "invalid" identifiers using 
setattr().

Example with PyPy:

$ pypy
Python 2.7.13 (0e7ea4fe15e82d5124e805e2e4a37cae1a402d4b, Apr 12 2018, 14:50:12)
 class A: pass
 
 a=A()
 setattr(a, "1", 2)
 getattr(a, "1")
2

 vars(a)
{'1': 2}
 a.__dict__
{'1': 2}

 a.1
  File "", line 1
a.1
^
SyntaxError: invalid syntax


The exact definition of "identifiers" is a common question. Recent examples:

* bpo-25205
* [Python-Dev] Arbitrary non-identifier string keys when using **kwargs
  https://mail.python.org/pipermail/python-dev/2018-October/155435.html

It would be nice to document the answer. Maybe in the Langage Specification, 
maybe in the setattr() documentation, maybe in a FAQ, maybe everywhere?

[issue33826] enable discovery of class source code in IPython interactively defined classes

[Thomas Viehmann]

Thomas Viehmann  added the comment:

Yeah, it's a shame no-one looked at the patch that seems to fix the underlying 
cause and now it's just a duplicate of a bug to improve error  messages.
On the up side, closing this bug will stop me from getting reminders about it.

I agree, adding an option to `getcwd()` would probably be a better approach and 
reduce some of the other potential confusion.

This seems to be a duplicate of issue12920. issue24491 was also a related issue 
closed as a duplicate of issue12920. So I propose closing this to continue the 
discussion in issue12920. Feel free to add in if I am missing something.

[issue34931] os.path.splitext with more dots

[Jan Novak]

Jan Novak  added the comment:

Yes, dot behaviour is well documented.

But splitext() is a function to split name and extension, not take care about 
hidden files.

Hidden files starting with dot is Unix like system feature.
https://en.wikipedia.org/wiki/Hidden_file_and_hidden_directory

Hidden files could have also extension.
Try for example create/rename .somename.jpg file in Ubuntu.
It is normal image with .jpg extension. You could open it etc.

You can't use standard python splitext() function to detect extension.

I know that change this standard python function is probably imposible due to 
backward compatibility. Bud extend it with new parameter could be possible. The 
change in 2007 was unfortunate/incomplete.

[issue1154351] add get_current_dir_name() to os module

[Serhiy Storchaka]

Serhiy Storchaka  added the comment:

We provide Python implementations for fnmatch, glob, realpath even if there are 
corresponding libc functions. This makes them available even on platforms that 
doesn't have native implementations in libc, avoids C limitations, and allow to 
add new options. I think it is not wrong to provide a Python implementation for 
get_current_dir_name().

My concerns are that while it can be useful for people that search for 
get_current_dir_name() in Python, it can be confused for other people.

* getcwd() and get_current_dir_name() are very similar, but have very different 
names. In what cases the one or other is preferable?

* On Windows getcwd() returns a path without resolved symbolic links, the same 
as get_current_dir_name(). Shouldn't we provide an option for getting current 
working directory with resolved symbolic links on all platforms? This will give 
us three options: resolved symlinks, unresolved symlinks, and platform-depended 
default.

* get_current_dir_name() works as desired only when current working directory 
was not changed since the start of the program. Any call of chdir() will make 
it an alias to getcwd().

* For some libc functions we add options to existing functions rather of 
duplicating the number of names in the os module. For example the dir_fd  
option instead of *at() functions. Wouldn't be better to add a buulean 
parameter (with platform-depending default) to getcwd()?

* What about pathlib? Does it need corresponding feature?
