[issue25188] regrtest.py improvement for Profile Guided Optimization builds

[Alecsandru Patrascu]

Alecsandru Patrascu added the comment:

Thank you for the tweaks. I tested the patch and it is all working fine. 
Without failure count the PGO run is even more transparent to the user. 

I tested your final version of the patch on several Linux server and regular 
desktop distributions and software configurations and I saw that test_eintr 
does not block and the entire PGO build finishes in good conditions every time.

ANN: python-ldap 2.4.21

[Michael Ströder]

Find a new release of python-ldap:

  http://pypi.python.org/pypi/python-ldap/2.4.21

python-ldap provides an object-oriented API to access LDAP directory
servers from Python programs. It mainly wraps the OpenLDAP 2.x libs for
that purpose. Additionally it contains modules for other LDAP-related
stuff (e.g. processing LDIF, LDAP URLs and LDAPv3 schema).

Project's web site:

  http://www.python-ldap.org/

Checksums:

$ md5sum python-ldap-2.4.21.tar.gz

Ciao, Michael.


Released 2.4.21 2015-09-25

Changes since 2.4.20:

Lib/
* LDAPObject.read_s() now returns None instead of raising
  ldap.NO_SUCH_OBJECT in case the search operation returned emtpy result.
* ldap.resiter.ResultProcessor.allresults() now takes new key-word
  argument add_ctrls which is internally passed to LDAPObject.result4()
  and lets the method also return response control along with the search
  results.
* Added ldap.controls.deref implementing support for dereference control

Tests/
* Unit tests for module ldif (thanks to Petr Viktorin)

mergeall 2.2, with os.scandir() speed optimization

[Mark Lutz]

There's a new version of the mergeall folder tree synchronization tool, which
uses Python 3.5's os.scandir(), if available, to radically speed up its trees
comparison phase.  In testing on Windows 7 and 10, the new call speeds mergeall
comparisons by a factor of 5 to 10, depending on devices.  This is due entirely
to the elimination of system calls that os.scandir() affords.

The savings is especially significant for large archives.  For a 78G target use
case of 50k files in 3k folders, comparison runtime fell from  40 to 7 seconds 
on a fast USB stick (6x); from 112 to 16 seconds on a slower stick (7x); and 
from 600 to 60 seconds on an ancient single-core machine (10x). 

Also note that the scandir() call is standard in the os module in 3.5, but can
also be had for older Python releases, including 2.7 and older 3.X, via a PyPI
package.  mergeall uses either form if present, and falls back on the original 
os.listdir() scheme as a last resort to continue supporting older Pythons 
(though a scandir() is now strongly recommended, for obvious reasons!).

All of which seems proof that language improvement and backward compatibility 
are not necessarily mutually exclusive.  The details:

While we are very knowledgeable, what we don't know is what went wrong. Can
you describe what you mean by "did not work"?

Preferably, if an error message was printed, please COPY and PASTE (don't
retype, especially not from memory) the error message?

If some other error occurred (Windows crash, computer caught fire...) please
describe it.

It may help if you explain the exact commands you used to install. Did you
use a text-based installer from the command line, or a GUI?

The more information you can give, the better the chances we can help.

Watch your capitalization!  Kilo is _NOT_ the same as kilo.  Case is significant in Python (as 
well as in many other programming languages).


Also, as has already been pointed out:  what you want here is kilo=get_input().  Along with the 
corresponding change to the get_input() definition.  This function does NOT need a passed parameter.

Django (Python Web Framework) Tutorial

[Cai Gengyang]

So I am using Mac OS X Yosemite Version 10.10.2, going through the django 
tutorial : https://docs.djangoproject.com/en/1.8/intro/tutorial01/ and learning 
to use it. Am currently on the 2nd chapter "Creating a Project" and got a 
question to ask :

This is the series of steps I took to reach this point :

A) I created a folder called "Weiqi" in my home directory. (named after the 
game I am best at!)

B) Then I typed the command $ cd Weiqi in the "Terminal"

CaiGengYangs-MacBook-Pro:~ CaiGengYang$ cd Weiqi --- input

and got this output :

CaiGengYangs-MacBook-Pro:Weiqi CaiGengYang$ --- output

C) Then I ran the following command in the Terminal : $ django-admin 
startproject mysite.
This created a mysite folder which appeared inside the original Weiqi folder in 
my home directory.
When I clicked on the mysite folder, there is a manage.py file and another 
mysite folder inside the original mysite folder.
When I click on the mysite folder, there are 4 files in it : __init__.py , 
settings.py , urls.py and wsgi.py.

D) The next chapter of the tutorial says this :
"Where should this code live?
If your background is in plain old PHP (with no use of modern frameworks), 
you're probably used to putting code under the Web server's document root (in a 
place such as /var/www). With Django, you don't do that. It's not a good idea 
to put any of this Python code within your Web server's document root, because 
it risks the possibility that people may be able to view your code over the 
Web. That's not good for security.
Put your code in some directory outside of the document root, such as 
/home/mycode."

Question : I am a little confused about the last paragraph : What exactly is a 
"directory outside of the document root, such as /home/mycode." and how do you 
"Put your code in this directory" ?

Thanks a lot !

Appreciate it

[issue19884] Importing readline produces erroneous output

[Berker Peksag]

Berker Peksag added the comment:

The version check doesn't work because 0ed1801bf4bd added #ifndef __APPLE__ to 
guard the code, so if you're using readline on OS X, that rl_variable_bind 
workaround won't work.

There are two alternatives:

1) convert ifndef to ifdef and add a check for the ``using_libedit_emulation`` 
variable.

#ifdef __APPLE__
if (using_libedit_emulation) {
...
...

looks like a common idiom in readline.c.


2) just skip the test if _READLINE_VERSION < 0x0603

[issue25220] Enhance and refactor test.regrtest (convert regrtest.py to a package)

[STINNER Victor]

STINNER Victor added the comment:

Ok, I started simply by *moving* code, without additionnal changes. I will 
watch for buildbots to ensure that no regression was added. The 
Lib/test/regrtest.py is kept to not break any existing tool. It looks like 
Lib/test/regrtest.py is very important in Python, much more than what I 
expected. It's used for PGO compilation, it's used by various scripts for 
different platforms, it's used in scripts to build Linux packages,etc.

I used "hg cp" to create new files to ensure that the history is not lost.

I will write new patches for the real refactoring work described in the first 
message. It will be much easier to review changes written after the code was 
moved. So we can discuss controversal changes like the creation of a class for 
libregrtest/main.py ;-)

ANN: A new version (0.3.8) of python-gnupg has been released.

[Vinay Sajip]

A new version of the Python module which wraps GnuPG has been

released. 

What Changed? 
= 
This is an enhancement and bug-fix release, and all users are encouraged to 
upgrade.
See the project website [1] for more information.

Brief summary: 


* Fixed #22: handled PROGRESS messages during verification and signing. 

* Fixed #26: handled PINENTRY_LAUNCHED messages during verification, 
  decryption and key generation. 

* Fixed #28: Allowed a default Name-Email to be computed even when neither of 
  LOGNAME and USERNAME are in the environment. 

* Fixed #29: Included test files missing from the tarball in previous versions. 

* Fixed #39: On Python 3.x, passing a text instead of a binary stream caused
  file decryption to hang due to a UnicodeDecodeError. This has now been
  correctly handled: The decryption fails with a "no data" status. 

* Fixed #41: Handled Unicode filenames correctly by encoding them on 2.x using
  the file system encoding.

* Fixed #43: handled PINENTRY_LAUNCHED messages during key export. Thanks to
  Ian Denhardt for looking into this. 

* Hide the console window which appears on Windows when gpg is spawned.
  Thanks to Kévin Bernard-Allies for the patch. 

* Subkey fingerprints are now captured. 

* The returned value from the list_keys method now has a new attribute,
  key_map, which is a dictionary mapping key and subkey fingerprints to
  the corresponding key's dictionary. With this change, you don't need to
  iterate over the (potentially large) returned list to search for a key with
  a given fingerprint - the key_map dict will take you straight to the key
  info, whether the fingerprint you have is for a key or a subkey. Thanks to
  Nick Daly for the initial suggestion. 

This release [2] has been signed with my code signing key: 

Vinay Sajip (CODE SIGNING KEY)  
Fingerprint: CA74 9061 914E AC13 8E66 EADB 9147 B477 339A 9B86 


However, due to some error the signature for the source distribution (.tar.gz)
didn't get uploaded. To rectify this, I have pasted it into the PyPI page for
the release [2].
What Does It Do? 
 
The gnupg module allows Python programs to make use of the 
functionality provided by the Gnu Privacy Guard (abbreviated GPG or 
GnuPG). Using this module, Python programs can encrypt and decrypt 
data, digitally sign documents and verify digital signatures, manage 
(generate, list and delete) encryption keys, using proven Public Key 
Infrastructure (PKI) encryption technology based on OpenPGP. 

This module is expected to be used with Python versions >= 2.4, as it 
makes use of the subprocess module which appeared in that version of 
Python. This module is a newer version derived from earlier work by 
Andrew Kuchling, Richard Jones and Steve Traugott. 

A test suite using unittest is included with the source distribution. 

Simple usage: 

>>> import gnupg 
>>> gpg = gnupg.GPG(gnupghome='/path/to/keyring/directory') 
>>> gpg.list_keys()

ANN: A new version (0.3.8) of python-gnupg has been released.

[Vinay Sajip]

A new version of the Python module which wraps GnuPG has been

released. 

What Changed? 
= 
This is an enhancement and bug-fix release, and all users are encouraged to 
upgrade.
See the project website [1] for more information.

Brief summary: 


* Fixed #22: handled PROGRESS messages during verification and signing. 

* Fixed #26: handled PINENTRY_LAUNCHED messages during verification, 
  decryption and key generation. 

* Fixed #28: Allowed a default Name-Email to be computed even when neither of 
  LOGNAME and USERNAME are in the environment. 

* Fixed #29: Included test files missing from the tarball in previous versions. 

* Fixed #39: On Python 3.x, passing a text instead of a binary stream caused
  file decryption to hang due to a UnicodeDecodeError. This has now been
  correctly handled: The decryption fails with a "no data" status. 

* Fixed #41: Handled Unicode filenames correctly by encoding them on 2.x using
  the file system encoding.

* Fixed #43: handled PINENTRY_LAUNCHED messages during key export. Thanks to
  Ian Denhardt for looking into this. 

* Hide the console window which appears on Windows when gpg is spawned.
  Thanks to Kévin Bernard-Allies for the patch. 

* Subkey fingerprints are now captured. 

* The returned value from the list_keys method now has a new attribute,
  key_map, which is a dictionary mapping key and subkey fingerprints to
  the corresponding key's dictionary. With this change, you don't need to
  iterate over the (potentially large) returned list to search for a key with
  a given fingerprint - the key_map dict will take you straight to the key
  info, whether the fingerprint you have is for a key or a subkey. Thanks to
  Nick Daly for the initial suggestion. 

This release [2] has been signed with my code signing key: 

Vinay Sajip (CODE SIGNING KEY)  
Fingerprint: CA74 9061 914E AC13 8E66 EADB 9147 B477 339A 9B86 


However, due to some error the signature for the source distribution (.tar.gz)
didn't get uploaded. To rectify this, I have pasted it into the PyPI page for
the release [2].
What Does It Do? 
 
The gnupg module allows Python programs to make use of the 
functionality provided by the Gnu Privacy Guard (abbreviated GPG or 
GnuPG). Using this module, Python programs can encrypt and decrypt 
data, digitally sign documents and verify digital signatures, manage 
(generate, list and delete) encryption keys, using proven Public Key 
Infrastructure (PKI) encryption technology based on OpenPGP. 

This module is expected to be used with Python versions >= 2.4, as it 
makes use of the subprocess module which appeared in that version of 
Python. This module is a newer version derived from earlier work by 
Andrew Kuchling, Richard Jones and Steve Traugott. 

A test suite using unittest is included with the source distribution. 

Simple usage: 

>>> import gnupg 
>>> gpg = gnupg.GPG(gnupghome='/path/to/keyring/directory') 
>>> gpg.list_keys() 

[{ 
... 
'fingerprint': 'F819EE7705497D73E3CCEE65197D5DAC68F1AAB2', 
'keyid': '197D5DAC68F1AAB2', 
'length': '1024', 
'type': 'pub', 
'uids': ['', 'Gary Gross (A test user) ']}, 
{ 
... 
'fingerprint': '37F24DD4B918CC264D4F31D60C5FEFA7A921FC4A', 
'keyid': '0C5FEFA7A921FC4A', 
'length': '1024', 
... 
'uids': ['', 'Danny Davis (A test user) ']}] 
>>> encrypted = gpg.encrypt("Hello, world!", ['0C5FEFA7A921FC4A']) 
>>> str(encrypted) 

'-BEGIN PGP MESSAGE-\nVersion: GnuPG v1.4.9 (GNU/Linux)\n 
\nhQIOA/6NHMDTXUwcEAf 
. 
-END PGP MESSAGE-\n' 
>>> decrypted = gpg.decrypt(str(encrypted), passphrase='secret') 
>>> str(decrypted) 

'Hello, world!' 
>>> signed = gpg.sign("Goodbye, world!", passphrase='secret') 
>>> verified = gpg.verify(str(signed)) 
>>> print "Verified" if verified else "Not verified" 

'Verified' 

As always, your feedback is most welcome (especially bug reports [3], 
patches and suggestions for improvement, or any other points via the 
mailing list/discussion group [4]). 

Enjoy!

[issue25240] Stack overflow in reprlib causes a core dump

[Ceridwen]

New submission from Ceridwen:

I have a linked list implementation made of nested tuples with a custom repr:

def __repr__(self):
return 'LinkedList(' + ', '.join(repr(v) for v in self) + ')'

(Iterating over a LinkedList returns just its contents.)

When using Raymond Hettinger's recipe for finding the size in memory of an 
object, 
https://code.activestate.com/recipes/577504-compute-memory-footprint-of-an-object-and-its-cont/?in=user-178123
 , when I set verbose=True and exceed the recursion limit with reprlib.repr, I 
get the following error:

Fatal Python error: Cannot recover from stack overflow.

Current thread 0x7fa24200d700 (most recent call first):
  File ".py", line 327 in __repr__
  File "/usr/lib/python3.4/reprlib.py", line 135 in repr_instance

  File "/usr/lib/python3.4/reprlib.py", line 54 in repr
  File "recipe.py", line 46 in sizeof
  [many instances of the above line repeated]
  ...
Aborted (core dumped)

The line in the recipe it fails when recursing on is:

print(s, type(o), repr(o), file=stderr)

On 2.7 it fails with a RuntimeError as I'd expect.

[issue25243] decouple string-to-boolean logic from ConfigParser.getboolean and offer as separate function

[Joshua Bronson]

New submission from Joshua Bronson:

ConfigParser.getboolean[1] has logic to convert strings like '0' and 'False' to 
False. This logic is generally useful in other contexts and need not be coupled 
to ConfigParser. Would you consider accepting a patch that factored this 
string-to-boolean logic out of ConfigParser into a standalone function, and 
changed ConfigParser.getboolean internally to call that?

Thanks for your consideration.

[issue25244] Idle: refine right-click behavior

[Terry J. Reedy]

New submission from Terry J. Reedy:

Spinoff from #24988, where I noted "The standard on Windows is to bring up a 
context menu on right-button-release, not on r-b-press." and asked "What about 
linux and mac?"

The question is relevant for 'Go to File/Line'.  Look at text where pressed or 
where released?

Current code in multiple places is
if macosxSupport.isAquaTk():
listbox.bind("", self.popup_event)
listbox.bind("", self.popup_event)
else:
listbox.bind("", self.popup_event)

Also for paste: where insert?

Thunderbird and Notepad++ move the insertion cursor on rb-press, That is the 
paste position even if the mouse is moved before release. Notepad does not move 
the insert cursor. MS Word is confusing, erasing the cursor when the menu is 
displayed and moving it when the menu goes away.

Additional note: Testing with my middle button, a press and release act the 
same as left click to move the insertion cursor to the mouse cursor. Moving my 
mouse while holding the middle button down moves the text pane within the text 
window. The insertion cursor is not moved. This is pretty much redundant with 
using the scroll wheel or scroll bar.

Event Handling Error in Python 3.4.3

[Supra1983 Tech]

I have a python script for a game and the problem is that after running the 
game, the blocks start falling, but the game over message is not popping up at 
proper times. Here is my script:

import pygame

import random

pygame.init()

display_width = 800
display_height = 600

black = (0,0,0)

Definitely. That's why we're encouraging him to handle specific exceptions.


try this:

   print(e.getcode(),disp)
   pass


You're aware that the "pass" there does nothing? Perhaps you're considering 
"continue"?


Normally when I write a specific clause like that it looks a bit like this:

 try this:
   ...
 except *urllib.error.HTTPError* as e:
   if e.getcode()==504:
 warning("about 504 error...")
 nombre = ''
   else:
 raise

This arranges that for _other_ HTTPErrors which I do not correctly handle that 
the exception is reraised.

apologise for my Spanish, which is nonexistent :-(

Ok. You original code says:

 try:
   r=requests.post(url, data=query_args)
 except:
   print "Connection error"

and presumably we think your code is hanging inside the requests.post
call? You should probably try to verify that, because if it is elsewhere
you need to figure out where (lots of print statements is a first start on
that).

I would open two terminals. Run your program until it hangs in one.

While it is hung, examine the network status. I'll presume you're on a
UNIX system of some kind, probably Linux? If not it may be harder (or just
require someone other than me).

If it is hung in the .post call, quite possibly it has an established
connecion to the target server - maybe that server is hanging.

The shell command:

 netstat -rn | fgrep 172.16.68.6 | fgrep 8090

will show every connection to your server hosting the URL "
http://172.16.68.6:8090/login.xml;. That will tell you if you have a
connection (if you are the only person doing the connecting from your
machine).

If you have the "lsof" program (possibly in /usr/sbin, so
"/usr/sbin/lsof") you can also examine the state of your hung Python
program. This:

 lsof -p 12345

will report on the open files and network connections of the process with
pid 12345. Adjust to suit: you can find your program's pid ("process id")
with the "ps" command, or by backgrounding your program an issuing the
"jobs" command, which should show the process id more directly.

One way this could be offered is as a new static method on bool (something like 
bool.parse_str?), but I of course defer to the better judgment of the Python 
core developers. I'd be happy to take a crack at a patch adding it wherever you 
like, if you like.

[issue18967] Find a less conflict prone approach to Misc/NEWS

[Nick Coghlan]

Nick Coghlan added the comment:

Just noting a potential practical benefit of the "NEWS entry first" approach 
that David suggests: I believe it will help encourage the creation of a 
succinct answer to "Why are we making this change?" as part of the patch review 
process.

That's then useful both during the patch review itself (since there's a shared 
understanding between reviewers and implementors of the goal to be achieved), 
as well as when the change is released (since there's hopefully a user centric 
explanation of *why* something changed, rather than merely *what* changed)

However, the key trap I'd like us to avoid falling into is letting the fact a 
particular approach falls short of our ideal approach deter the introduction of 
interim improvements. We're going to need the checked in filesystem database 
anyway to backfill historical NEWS entries after switching to a generated NEWS 
file, so it seems harmless to me to switch to it early and then incrementally 
add to it until a tracker based solution is available.

Added equivalent completion window patch.  Would have preferred confirmation 
that Idle versions work, but 3.4.4rc1 is only a week away and I think having

[issue25239] HTMLParser handle_starttag replaces entity references in attribute value even without semicolon

[Sean Liu]

New submission from Sean Liu:

In the document of HTMLParser.handle_starttag, it states "All entity references 
from html.entities are replaced in the attribute values." However it will 
replace the string if it matches ampersand followed by the entity name without 
the semicolon.

For example foo will produce "t=buy¤cy=usd" 
as the value of href attribute due to "curren" is the entity name for the 
currency sign.

[issue25239] HTMLParser handle_starttag replaces entity references in attribute value even without semicolon

[Ezio Melotti]

Ezio Melotti added the comment:

This seems indeed to be a bug.  The relevant bit seems to be at 
http://www.w3.org/TR/html5/syntax.html#consume-a-character-reference :

"""
If the character reference is being consumed as part of an attribute, and the 
last character matched is not a ";" (U+003B) character, and the next character 
is either a "=" (U+003D) character or an alphanumeric ASCII character, then, 
for historical reasons, all the characters that were matched after the U+0026 
AMPERSAND character (&) must be unconsumed, and nothing is returned. However, 
if this next character is in fact a "=" (U+003D) character, then this is a 
parse error, because some legacy user agents will misinterpret the markup in 
those cases.
"""

Off the top of my head, this paragraph is not implemented in HTMLParser (and it 
should).
Also note that foo is not valid HTML and 
the & should have been escaped with .

[issue25241] ctypes: access violation reading

[eryksun]

eryksun added the comment:

The default function pointer restype is c_int, and the default integer argument 
conversion is also c_int. However, the handle returned by FindFirstVolume is a 
pointer to a private structure that it uses for the volume enumeration, so you 
must set restype to a pointer type. Similarly, if restype is a simple type that 
gets converted to a Python integer (e.g. wintypes.HANDLE), then you must either 
set FindNextVolumeW.argtypes or manually wrap the handle value (e.g. vhandle = 
wintypes.HANDLE(vhandle)). The default c_int conversions will only work if the 
address happens to fit in a 32-bit int. 

Don't forget to call FindVolumeClose if the process is expected to continue. 
Otherwise you're leaking memory.

Also, if you're defining function pointer prototypes for a library, please do 
not use ctypes.cdll or ctypes.windll. The loaders are global to ctypes and by 
design cache the loaded library, which by design caches function pointers. 
Projects such as pyreadline and colorama have demonstrated the problems that 
this creates due to inconsistent prototype definitions, especially for commonly 
used Win32 APIs.

Here is one way to rewrite your code to have it work more reliably:

import ctypes
from ctypes import wintypes

kernel32 = ctypes.WinDLL('kernel32', use_last_error=True)

kernel32.FindFirstVolumeW.restype = wintypes.HANDLE
kernel32.FindNextVolumeW.argtypes = (wintypes.HANDLE,
 wintypes.LPWSTR,
 wintypes.DWORD)
kernel32.FindVolumeClose.argtypes = (wintypes.HANDLE,)

INVALID_HANDLE_VALUE = wintypes.HANDLE(-1).value
ERROR_NO_MORE_FILES = 18

def list_volumes():
vname = ctypes.create_unicode_buffer(wintypes.MAX_PATH)
vhandle = kernel32.FindFirstVolumeW(vname, len(vname))
if vhandle == INVALID_HANDLE_VALUE:
raise ctypes.WinError(ctypes.get_last_error())
volumes = []
try:
while True:
volumes.append(vname.value)
if not kernel32.FindNextVolumeW(vhandle, vname, len(vname)):
last_error = ctypes.get_last_error()
if last_error == ERROR_NO_MORE_FILES:
break
else:
raise ctypes.WinError(last_error)
finally:
if not kernel32.FindVolumeClose(vhandle):
raise ctypes.WinError(ctypes.get_last_error())
return volumes

if __name__ == '__main__':
for volume in list_volumes():
print(volume)

Python program on induction heating

[Roïya souissi]

Hello,
I have realized last year a mini project on induction heating and its 
application onto thermoelectricity. To back up my theoretical work, I created a 
python program ( I used mainly dictionnaries, PIL library and tkinter library). 
I have created a personal blog (https://souissiroiya.wordpress.com/) in a bid 
to publish my future works and projects and his the url to the python program 
in case you want to check it out (https://souissiroiya.wordpress.com/2015 ...

[issue25125] "Edit with IDLE" does not work for shortcuts

[eryksun]

eryksun added the comment:

A LNK shortcut should support the same commands (e.g. open, edit) as its 
target. This works for me in Windows 10. 

BTW, I don't see how to ShellExecute a subcommand documented on MSDN. One way 
is to just pass the subkey path as the 'verb', e.g. 
r"editwithidle\shell\edit35". Probably it's just passed along to RegOpenKeyEx 
as the subkey, so this shouldn't be used in practice. Could the installer 
create a simple "edit" command? It doesn't have to be smart about it. Just 
overwrite the current value, and let a per-user install take precedence.

[issue23600] tizinfo.fromutc changed for tzinfo wih StdOffset=0, DstOffset=1

[Tim Peters]

Tim Peters added the comment:

I expect Peter is correct:  the C fromutc() doesn't match the logic of the 
Python fromutc(), and there are no comments explaining why the C version 
changed the logic.

The last 4 lines of his `time_issues.py` show the difference.  The simplified 
UKSummerTime tzinfo always says the total UTC offset and the DST offset are 
+1:00:00.  The Python .fromutc() adds that hour to the datetime passed in, but 
the C .fromutc() does not.  That's because they implement different functions, 
not because Peter is using .fromutc() ;-)

[issue9051] Improve pickle format for timezone aware datetime instances

[Serhiy Storchaka]

Serhiy Storchaka added the comment:

For now "_utc" is not a part of API. When use it in pickling, you implicitly 
make it a part of API, and should support it forever (and force other Python 
implementations to support it). As far as it looks as implementation detail, 
there is a risk that the "_utc" variable can be renamed and this will break 
pickle compatibility.

[issue24972] IDLE: revisit text highlighting for inactive windows on win32

[Terry J. Reedy]

Terry J. Reedy added the comment:

I verified that inactiveselectbackground exists and starts as ''.  Since it 
should match the active selectbackground on all systems, as set by the current 
theme. I will try adding a line where selection colors are set: 
EditorWindow.ResetColorizer:
self.text.config(
...
selectforeground=select_colors['foreground'],
selectbackground=select_colors['background'],
inactiveselectbackground=select_colors['background']
)
I believe this is the only place where this is needed.  The select colors are 
used for a different widget in TreeWidget. The use in ParenMatch for 'paren' 
tag should be temporary.

We will need to reconsider the 'found' highlight and the select versus found 
usage after this change.

Ok.

As for the next chapter(Database setup), I opened up mysite/settings.py as per 
the instructions on the Django tutorial.

However, when I try to run the following command : $ python manage.py migrate 
to create the tables in the database,

CaiGengYangs-MacBook-Pro:Weiqi CaiGengYang$ python manage.py migrate  input

I get the following error message :

/Library/Frameworks/Python.framework/Versions/2.7/Resources/Python.app/Contents/MacOS/Python:
 can't open file 'manage.py': [Errno 2] No such file or directory  output

Any idea how to solve this issue?

Thanks a lot !

A memory-mapped file can be renamed, so replacing the executable is
doable. The new name has to be on the same volume. That's doable. The
problem is that Windows doesn't allow deleting the file. Maybe pip
could spawn a clean-up script to which it pipes the list of renamed
files. The script waits for pip to exit and then tries to remove the
files.

Django is a web application framework.  So, you have to use it together with
a web server.  The "document root" is the directory where the web server
expects to find files to be served as web pages.

You said you put the Django project code in a subdirectory of your home
directory.  That should be fine.

I agree with Serhiy that surrogates are a Unicode thing, not just related to 
the “surrogatepass” handler.

Adding them to “codecs” makes sense to me. The most important one, 
handle_surrogateescape() or equivalent, is closely related to the error handler 
of that module.

Having handle_surrogateescape or equivalent would probably be useful for Issue 
25184 (displaying an arbitrary file path in a UTF-8 HTML file).

[issue25194] Register of Financial Interests for core contributors

[Nick Coghlan]

Nick Coghlan added the comment:

Posting an alternate draft that takes the approach MAL suggested, emphasising 
the personal motivation side of things.

This one doesn't attempt to pre-categories the list of contributors - instead, 
I'd expect us to do that based on analysis of the raw text.

The opening section also makes it clear that we're not shifting the goal posts 
on becoming a core contributor - the only required disclosure remains that 
which is needed to sign the CLA and submit the signed copy to the PSF.

I like this version a lot better then the previous draft, but am still open to 
suggestions for improving both the formatting and the content.

[issue25242] Failed tests for Python 3.5.0 on shared virtual host

[Serhiy Storchaka]

Serhiy Storchaka added the comment:

May be /tmp is mounted on a filesystem that forbids setting the execution bit.

[issue23329] _ssl cannot be compiled with LibreSSL anymore (on OpenBSD 5.5) because of ALPN

[Remi Pointel]

Remi Pointel added the comment:

Good, I think we should test on a machine with a version of openssl that does 
not support ALPN to be sure.

[issue25242] Failed tests for Python 3.5.0 on shared virtual host

[Open Genomes]

New submission from Open Genomes:

Several tests for Python 3.5.0 failed. 
The install is a local one on a shared virtual server from bluehost.com
This is a local user install, with a prefix in $HOME/python directory. 
Output of uname -a:
Linux box874.bluehost.com 3.12.35.1418868052 #1 SMP Wed Dec 17 20:04:02 CST 
2014 x86_64 x86_64 x86_64 GNU/Linux

It would seem that there are no permissions to spawn() a new process, and to 
write temporary files to /tmp

The tests should be able to work on a virtual server, or the test should check 
if there are permissions to fork a process and write to a system-wide temporary 
directory. Of course many installations use Python on virtual hosts and often 
the system-wide default installation on Linux systems is 2.7.0. The tests need 
to fail gracefully or accommodate the lack of permissions for to fork new 
processes and write to system-wide temporary directories.

This is a limitation of Windows: you can't replace the executable that
you're currently running.  To work around this, do "python -m pip
install --upgrade pip" instead.  If you have the Python Launcher for
Windows installed (included with Python 3.3+), you can use in place of
'python' in that command, and be very sure about which python's pip is
being upgraded.
