[issue46830] Add Find functionality to Squeezed Text viewer

[Jeff Cagle]

New submission from Jeff Cagle :

Squeezed text output currently opens in a viewer whose only functionality is 
scrolling.  Adding the Find widget a la IDLE would make the viewer much more 
useful.

[issue45435] delete misleading faq entry about atomic operations

That's where I noticed it, but it seemed the wrong place to explore this way.

Steven is right, I'm over-stating the case. And although valid that this is 
CPython specific, it's well sign-posted and I'm just being thin-skinned.

Serhiy writes:
> sort() is atomic, even if GIL is released during executing custom __lt__. It 
> is guaranteed that no operations on the list in other threads can affect the 
> result of sort().

The strategy noted here: 
https://github.com/python/cpython/blob/2d21612f0dd84bf6d0ce35bcfcc9f0e1a41c202d/Objects/listobject.c#L2261-L2265
does guarantee that, which I hadn't noticed. What if during the release of the 
GIL, another thread appends to L? In my simple experiment I get a ValueError 
and the modifications are lost. I think that is not thread-safe.

Serhiy also writes:

> I do not understand what non-atomic you see in x = L[i]. The value of x is 
> determined by values of L and i at the start of the operation. GIL is not 
> released during indexing L, and if it is released between indexing and 
> assignment, it does not affect the result.

and Steven:

> Does that matter though? I think that's a distinction that makes no 
difference.

> We know that another thread could change the L or the i before the 
assignment, if they are global. But once the L[i] lookup has occurred, 
it doesn't matter if they change. It's not going to affect what value 
gets bound to the x.

Fair enough. Atomicity is a bit slippery, I find. It depends where the critical 
region starts. Thinking again, it's not the assignment that's the issue ...

L is pushed
i is pushed
__getitem__ is called
x is popped

It is possible, if i and L are accessible to another thread and change after L 
is pushed, that x is given a value composed from an i and an L that never 
existed concurrently in the view of the other thread. Straining at gnats here, 
but atomicity is a strong claim.

And on the point about re-ordering and CPUs, I can't imagine re-ordering that 
effectively changes the order of byte codes. But do CPython threads run in 
separate CPUs, or is that only when we have multiple interpreters? If so, and L 
were in a hot memory location (either the variable or its content), this could 
be inconsistent between threads. Sorry, I don't know the memory coherence 
CPython has: I know I couldn't rely on it in Java.

I'm just arguing that the section gives advice that is *nearly* always right, 
which is a horrible thing to debug. I'll stop stirring.

[issue45435] delete misleading faq entry about atomic operations

[Jeff Allen]

Jeff Allen  added the comment:

I'm interested in Thomas' reasons, but here are some of mine (as far as I 
understand things):

1. It is specific to one interpreter implemented in C, equipped with a GIL, and 
on certain assumptions about the byte code interpreter and the implementation 
of built-ins, that may not hold long-term. 

2. In x = L[i], the index and assignment are distinct actions (in today's byte 
code), allowing L or i to change before x is assigned. This applies to multiple 
other of the examples.

3. A compiler (even a CPU) is free to re-order operations and cache values in 
unguessable ways, on the assumption of a single thread.

4. Code written on these principals is fragile. It only takes the replacement 
of a built-in with sub-class redefining __getitem__ (to support some worthy aim 
elsewhere in the code) to invalidate it.

5. sort() is not atomic if an element is of a type that overrides comparison in 
Python. (Nor is modifying a dictionary if __hash__ or __eq__ are redefined.)
 

If you want retain the question, with a better answer, the last sentence is 
good: "When in doubt, use a mutex!", accompanied by "Always be in doubt."

[issue44481] Tkinter config() minor documentation bug for shorthand options

[Jeff S]

New submission from Jeff S :

The documentation page https://docs.python.org/3/library/tkinter.html states 
"Passing the config() method the name of a shorthand option will return a 
2-tuple, not 5-tuple."  While config() without argument does return a map that 
yields references like this, if config() is given the shorthand name as an 
argument, it follows the reference to the long option name and does yield the 
full 5-tuple.

To demonstrate the difference:

from tkinter import Tk

Tk().config()['bg']

Tk().config('bg')

[issue43173] Python Windows DLL search paths

[Jeff Moguillansky]

New submission from Jeff Moguillansky :

Hi,
What's the correct way to set the DLL search path when running a python script?

It seems that it doesn't search the directories specified in PATH environment 
variable. 

FYI: For debugging the DLL loading issues, I'm using "Process Monitor" from 
sysinternals:
https://docs.microsoft.com/en-us/sysinternals/downloads/procmon,
but please share any tips if you have a better approach.

Also, the Python error message is not very informative:
when loading a python module (built using Cython), if it fails to load a 
specific DLL, it says 
"import module  failed, DLL not found" but it doesn't say the name 
of the actual DLL that is not found.
It would be helpful if it listed the actual name of the DLL that it cannot find.

[issue42894] Debugging native Python modules on Windows with Visual Studio Toolchain

[Jeff Moguillansky]

New submission from Jeff Moguillansky :

I have a question regarding debugging native Python modules on Windows, with 
Visual Studio toolchain:

Currently I have a native module (native C code), along with Python API 
bindings (via Cython), and finally Python code that invokes the native module.  
I also use various third-party python modules like Pillow, etc.  

In order to debug on Windows, I have to use the following tricks:
1) Build the native module in Release Mode
2) Disable Compiler Optimization
3) Enable Debug symbols

I can't just use Python distutils out of the box, I have to manually modify the 
build commands to enable Debugging.

If I just try to build the native module in Debug mode, I get Visual Studio 
compile errors related to: not being able to mix code built with different C++ 
runtime libraries.  
Some of the 3rd-party Python modules are only available as Release builds (not 
Debug builds).

I'm wondering if anyone has encountered a similar issue, and what's your 
advice?  

On Linux, GNU toolchain, this isn't an issue.  The toolchain lets you mix 
release and debug libraries, no problem.

[issue42863] Python venv inconsistent folder structure on windows

[Jeff Moguillansky]

New submission from Jeff Moguillansky :

When creating a virtual environment on windows using venv, the folder 
structure: "Scripts", "Include", "Lib", is inconsistent with other platforms 
(e.g. "include", "lib", "bin", etc).  

This causes various integration issues.  

For example, suppose we want to build a native C library, and install it to the 
folder structure generated by the virtual environment.  
The pkg-config file assumes a folder structure of "include", "lib", "bin", and 
the generated pkg-config files are inconsistent with the python virtual 
environment folder structure.  

Can we have a consistent folder structure across platforms?

Interesting PEG thing.  C++ compilers are getting better at suggesting
fixes for minor syntax errors (in 2011 on MSVC I remember seeing pages of

lagging behind in this regard.. will check out superhelp, maybe it'll help
me patiently wait for the day where the python compiler does machine
learning on my specific style of mistakes to suggest fixes lol.

See attached image.  Would be nice if it printed "SyntaxError: unbalanced
parens" as it can difficult to see the problem if code like this is run in
an environment that only prints the problematic line, which in this case
the compiler is confused and one line off.

[issue40320] Add ability to specify instance of contextvars context to Task() & asyncio.create_task()

[Jeff Laughlin]

New submission from Jeff Laughlin :

As a test engineer I want to be able to run async test fixtures and test cases 
in different async tasks with the same Context. Not a copy; the same specific 
instance of contextvars.Context().

I do NOT want the task to run in a COPY of the context because I want mutations 
to the context to be preserved so that I can pass the mutated context into 
another async task.

I do NOT want the task to inherit the potentially polluted global context.

class Task currently unconditionally copies the current global context and has 
no facility for the user to override the context.

Therefor I propose adding a context argument to the Task constructor and to 
create_task()

It should be noted that this argument should not be used for "normal" 
development and only for "weird" stuff like test frameworks.

I should also note that Context().run() is not useful here because it is not 
async and there is no obvious existing async equivalent. This proposal would be 
roughly equivalent.

I should also note that a hack like copying the items from one context to 
another will not work because it breaks ContextVar set/reset. I tried this. It 
was a heroic failure. It must be possible to run a task with an exist instance 
of context and not a copy.

Here is a real-world use case: 
https://github.com/pytest-dev/pytest-asyncio/pull/153/files

Here is the hacked Task constructor I cooked up:

class Task(asyncio.tasks._PyTask):
def __init__(self, coro, *, loop=None, name=None, context=None):
...
self._context = context if context is not None else copy_context()

self._loop.call_soon(self.__step, context=self._context)
asyncio._register_task(self) 


if folks are on board I can do a PR

[issue39959] (Possible) bug on multiprocessing.shared_memory

[Jeff Fischer]

Jeff Fischer  added the comment:

I've run into the same problem. It appears that the SharedMemory class is 
assuming that all clients of a segment are child processes from a single 
parent, and that they inherit the same resource_tracker. If you run separate, 
unrelated processes, you get a separate resource_tracker for each process. 
Then, when a process does a close() followed by a sys.exit(), the resource 
tracker detects a leak and unlinks the segment.

In my application, segment names are stored on the local filesystem and a 
specific process is responsible for unlinking the segment when it is shut down. 
I was able to get this model to work with the current SharedMemory 
implementation by having processes which are just doing a close() also call 
resource_tracker.unregister() directly to prevent their local resource trackers 
from destroying the segment.

I imagine the documentation needs some discussion of the assumed process model 
and either: 1) a statement that you need to inherit the resource tracker from a 
parent process, 2) a blessed way to call the resource tracker to manually 
unregister, or 3) a way to disable the resource tracker when creating the 
SharedMemory object.

[issue39639] Remove Suite node from AST

[Jeff Allen]

Jeff Allen  added the comment:

Jython uses the reference grammar and ASDL as a way to ensure it is Python we 
approximate, not some subtly different language. The presence of Suite here 
gives rise to a class 
(https://github.com/jythontools/jython/blob/v2.7.2b3/src/org/python/antlr/ast/Suite.java)
 and we actually use instances of it in the compiler 
(https://github.com/jythontools/jython/blob/v2.7.2b3/src/org/python/compiler/CodeCompiler.java#L2389).

It is a bit of a wart, to have a Jython-specific type here: somewhat defeating 
the object of using the same source. I expect there was a good reason: perhaps 
there was no better way to express the commonality between Interactive and 
Module. It was all before my involvement.

I would try to avoid needing it in Jython 3, and if we can't, it doesn't look 
hard to manage the variation our copy. It's not like we copy these files 
mechanically from from CPython during a build.

+1 on removing it.

[issue39469] Support for relative home path in pyvenv.cfg

[Jeff Edwards]

Jeff Edwards  added the comment:

Interesting, I hadn’t realized that it would embed the FQ Executable path,
but that does make sense overall.  I guess I had always planned on fixing
the ‘bin’ directory anyway afterwards, it’s just that the lack of relative
home made it significantly harder to encapsulate multiple environments
running with the same interpreter without having to do a complete
reinstall, and venv did seem like the best and most-pythonic way to do it.

I’ll think about it a bit more

[issue39469] Support for relative home path in pyvenv.cfg

[Jeff Edwards]

Jeff Edwards  added the comment:

I would say they’re not designed to be, but the also aren’t designed to not
be portable.  This is often useful where open network access isn’t
reasonable, so access to Pip/pipx/pipenv is limited at best.

Suffice to say, is there a significant reason to not allow it?

[issue39469] Support for relative home path in pyvenv.cfg

[Jeff Edwards]

New submission from Jeff Edwards :

Currently, the interpreter only supports absolute paths for the 'home' 
directory in the pyvenv.cfg file.  While this works when the interpreter is 
always installed at a fixed location, it impacts the portability of virtual 
environments and can make it notably more-difficult if multiple virtual 
environments are shipped with a shared interpreter and are intended to be 
portable and working in any directory.

Many of these issues can be solved for if 'home' can use a directory relative 
to the directory of the pyvenv.cfg file.  This is detected by the presence of a 
starting '.' in the value.

A common use-case for this is that a script-based tool (e.g. black or 
supervisor) may be shipped with a larger portable application where they are 
intended to share the same interpreter (to save on deployment size), but may 
have conflicting dependencies.  Since the application only depends on the 
executable scripts, those packages could be packaged into  their own virtual 
environments with their dependencies.

[issue38926] MacOS: 'Install certificates.command' has no effect

[Jeff Berkowitz]

New submission from Jeff Berkowitz :

After using the Python-supported installer to install 3.8.0 on my 
employer-owned Mac running High Sierra (10.13.6), the 'Install 
Certificates.command' had no apparently effect on the behavior of Python.

The behavior before executing the script was that a Python program using 
urllib3 was unable to verify that public certificate of github.com. Using curl, 
I could download via the desired URL. But the Python program could not, 
consistently throwing SSL verify errors instead.

I ran the command script several times. I verified that the symlink cert.pem 
was created in /Library/Frameworks/Python.framework/Versions/3.8/etc/openssl 
and that it contained "../../lib/python3.8/site-packages/certifi/cacert.pem" 
and I verified that the latter file had content (4558 lines) and was readable. 
And that it did contain the root cert for Github.

But despite that and despite multiple new shell windows and so on, I could 
never get Python to regard the certs. I eventually worked around this by: 
export SSL_CERT_FILE=/etc/ssl/cert.pem. After this, the Python program using 
urllib3 could verify Github.com's public cert. But as I understand things, this 
env var is actually regarded by the OpenSSL "C" library itself, not Python.(?) 
Which, if true, raises the question of why this was necessary.

Of course, there's quite likely something in my environment that is causing 
this. But it would be nice to know what.

[issue37886] PyStructSequence_UnnamedField not exported

[Jeff Robbins]

Jeff Robbins  added the comment:

Editing one line in structseq.h seems to fix the issue.

I changed this

extern char* PyStructSequence_UnnamedField;

to

PyAPI_DATA(char*) PyStructSequence_UnnamedField;

rebuilt, and now my C extension can use PyStructSequence_UnnamedField.

[issue37886] PyStructSequence_UnnamedField not exported

[Jeff Robbins]

New submission from Jeff Robbins :

Python 3.8.0b3 has the fixed 
https://docs.python.org/3/c-api/tuple.html#c.PyStructSequence_NewType, but one 
of the documented features of PyStructSequence is the special 
https://docs.python.org/3/c-api/tuple.html#c.PyStructSequence_UnnamedField 
which is meant to be used for unnamed (and presumably also "hidden") fields.

However, this variable is not "exported" (via __declspec(dllexport) or the 
relevant Python C macro) and so my C extension cannot "import" it and use it.

My guess is that this passed testing because the only tests using it are 
internal modules linked into python38.dll, which are happy with the `extern` in 
the header:

Include\structseq.h:extern char* PyStructSequence_UnnamedField;

[issue35662] Windows #define _PY_EMULATED_WIN_CV 0 bug

[Jeff Robbins]

Jeff Robbins  added the comment:

Steve, sorry to be dense, but I'm unfortunately ignorant as to what tests I 
ought to be running.  The only test I have right now is much too complicated, 
and I'd rather be running some official regression test that reveals the 
problem without my app code, if possible.

[issue35662] Windows #define _PY_EMULATED_WIN_CV 0 bug

[Jeff Robbins]

Jeff Robbins  added the comment:

Steve, I did some more digging into why the native condition variable approach 
might be causing problems on Windows.  Testing my fix revealed that there is at 
least one place in Modules\overlapped.c that either 

a) waits too long to call GetLastError(), or 

b) reveals an expectation that Py_END_ALLOW_THREADS won't change the results of 
GetLastError().



Py_BEGIN_ALLOW_THREADS
ret = GetQueuedCompletionStatus(CompletionPort, ,
, , Milliseconds);
save_err = GetLastError();
Py_END_ALLOW_THREADS

err = ret ? ERROR_SUCCESS : GetLastError();





The problem in this code is that it allows *other* Windows API calls between 
the original Windows API call (in this case GetQueuedCompletionStatus()) and 
the call to GetLastError().  If those other Windows API calls change the 
thread-specific GetLastError state,
the info we need is lost.


To test for this possibility, I added a diagnostic test right after the code 
above



if (!ret && (err != save_err)) {
printf("GetQueuedCompletionStatus returned 0 but we lost the error=%d 
lost=%d Overlapped=%d\n", save_err, err, (long)Overlapped);
}




 and ran a test that eventually produced this on the console:



GetQueuedCompletionStatus returned 0 but we lost the error=258 lost=0 
Overlapped=0




error 258 is WAIT_TIMEOUT.  The next lines of code are looking for that "error" 
in order to decide if GetQueuedCompletionStatus failed, or merely timed out.



if (Overlapped == NULL) {
if (err == WAIT_TIMEOUT)
Py_RETURN_NONE;
else
return SetFromWindowsErr(err);
}



So the impact of this problem is severe.   Instead of returning None to the 
caller (in this case _poll in asyncio\windows_events.py), it will raise an 
error!



while True:
status = _overlapped.GetQueuedCompletionStatus(self._iocp, ms)
if status is None:
break




And, to make things extra confusing, the error raised via 
SetFromWindowsErr(err) (where err == 0) ends up looking like this:



OSError: [WinError 0] The operation completed successfully




A valid WAIT_TIMEOUT thus gets converted to a Python error, but also loses the 
original Windows Error Code of 258, so you are left scratching your head about 
how a WinError 0 (ERROR_SUCCESS) could have crashed your call to, say, 
asyncio.run()? (See traceback below.)


So either we need to make sure that all calls to GetLastError() are made 
immediately after the relevant Windows API call, without any intervening other 
Windows API calls, and thereby prevent case a) above, or as in case b), the GIL 
code (using either emulated or native condition variables from condvar.h) needs 
to preserve the Error state. 

Some code in Python\thread_nt.h in fact does this already, e.g.



void *
PyThread_get_key_value(int key)
{
/* because TLS is used in the Py_END_ALLOW_THREAD macro,
 * it is necessary to preserve the windows error state, because
 * it is assumed to be preserved across the call to the macro.
 * Ideally, the macro should be fixed, but it is simpler to
 * do it here.
 */
DWORD error = GetLastError();
void *result = TlsGetValue(key);
SetLastError(error);
return result;
}



Of course there might be *other* problems associated with using native 
condition variables on Windows, but this is the only one 
I've experienced after some fairly heavy use of Python 3.7.2 asyncio on Windows.

[issue35580] Windows IocpProactor: CreateIoCompletionPort 4th arg 0xffffffff -- why is this value the default?

[Jeff Robbins]

Jeff Robbins  added the comment:

I don't understand why 0 would be safer.  Since asyncio can only service this 
IOCP from its single threaded event loop, I would have thought 1 would express 
the intent better.  

Why not convey to the OS what we're up to, in case that helps it do a better 
job or reduces resource footprint?

I see that someone else already noticed this broken function, but I guess
it was left broken because of other issues with using condition variables
instead of the emulated ones?

Still, the code is wrong as written...

[issue35662] Windows #define _PY_EMULATED_WIN_CV 0 bug

[Jeff Robbins]

Jeff Robbins  added the comment:

I did a search and couldn't find exactly this issue. This issue is about a
broken function. It is broken because it treats a timeout as a fatal error
which crashes your Python program.

I supplied a proposed fix for the function.

If there are other known issues or tests, happy to dig in.  Seems a shame
that Python 3 on Windows needs to be running on emulated condition
variables when the OS has (apparently) working actual ones.

[issue35662] Windows #define _PY_EMULATED_WIN_CV 0 bug

[Jeff Robbins]

New submission from Jeff Robbins :

Python 3.x defaults to using emulated condition variables on Windows.  I tested 
a build with native Windows condition variables (#define _PY_EMULATED_WIN_CV 
0), and found a serious issue.

The problem is in condvar.h, in this routine:


/* This implementation makes no distinction about timeouts.  Signal
 * 2 to indicate that we don't know.
 */
Py_LOCAL_INLINE(int)
PyCOND_TIMEDWAIT(PyCOND_T *cv, PyMUTEX_T *cs, long long us)
{
return SleepConditionVariableSRW(cv, cs, (DWORD)(us/1000), 0) ? 2 : -1;
}


The issue is that `SleepConditionVariableSRW` returns FALSE in the timeout 
case.  PyCOND_TIMEDWAIT returns -1 in that case. 

But... COND_TIMED_WAIT, which calls PyCOND_TIMEDWAIT, in ceval_gil.h, fatals(!) 
on a negative return value


#define COND_TIMED_WAIT(cond, mut, microseconds, timeout_result) \
{ \
int r = PyCOND_TIMEDWAIT(&(cond), &(mut), (microseconds)); \
if (r < 0) \
Py_FatalError("PyCOND_WAIT(" #cond ") failed"); \



I'd like to suggest that we use the documented behavior of the OS API call 
already being used (SleepConditionVariableSRW 
https://docs.microsoft.com/en-us/windows/desktop/api/synchapi/nf-synchapi-sleepconditionvariablesrw)
 and return 0 on regular success and 1 on timeout, like in the _POSIX_THREADS 
case.  

"""
Return Value
If the function succeeds, the return value is nonzero.

If the function fails, the return value is zero. To get extended error 
information, call GetLastError.

If the timeout expires the function returns FALSE and GetLastError returns 
ERROR_TIMEOUT.
"""

I've tested this rewrite -- the main difference is in the FALSE case, check 
GetLastError() for ERROR_TIMEOUT and then *do not* treat this as a fatal error.
 


/*
 * PyCOND_TIMEDWAIT, in addition to returning negative on error,
 * thus returns 0 on regular success, 1 on timeout
*/
Py_LOCAL_INLINE(int)
PyCOND_TIMEDWAIT(PyCOND_T *cv, PyMUTEX_T *cs, long long us)
{
BOOL result = SleepConditionVariableSRW(cv, cs, (DWORD)(us / 1000), 0);

if (result)
return 0;

if (GetLastError() == ERROR_TIMEOUT)
return 1;

return -1;
}


I've attached the test I ran to reproduce the crash.

[issue35599] asyncio windows_events.py IocpProactor bug

[Jeff Robbins]

New submission from Jeff Robbins :

The close() method of IocpProactor in windows_events.py has this code in its 
close() method:

while self._cache:
if not self._poll(1):
logger.debug('taking long time to close proactor')

The bug is that self._poll() has *no* return statements in it, and so returns 
None no matter what.  Which makes the "if not" part confusing, at best.  At 
worst, it might reflect a disconnect with the author's intent.

I added a bit more logging and re-ran my test:

while self._cache:
logger.debug('before self._poll(1)')
if not self._poll(1):
logger.debug('taking long time to close proactor')
logger.debug(f'{self._cache}')


logger output:

20:16:30.247 (D)   MainThread  asyncio: before self._poll(1)
20:16:30.248 (D)   MainThread  asyncio: taking long time to 
close proactor
20:16:30.249 (D)   MainThread  asyncio: {}


Obviously 1 millisecond isn't "taking a long time to close proactor".  Also of 
interest, the _cache is now empty.  

I think the intent of the author must have been to check if the call to 
._poll() cleared out any possible pending futures, or waited the full 1 second. 
 Since ._poll() doesn't return any value to differentiate if it waited the full 
wait period or not, the "if" is wrong, and, I think, the intent of the author 
isn't met by this code.

But, separate from speculating on "intent", the debug output of "taking a long 
time to close proactor" seems wrong, and the .close() code seems disassociated 
with the implementation of ._poll() in the same class IocpProactor in 
windows_events.py.

[issue35580] Windows IocpProactor: CreateIoCompletionPort 4th arg 0xffffffff -- why is this value the default?

[Jeff Robbins]

Jeff Robbins  added the comment:

Per 
https://stackoverflow.com/questions/38133870/how-the-parameter-numberofconcurrentthreads-is-used-in-createiocompletionport,
 it seems that `NumberOfConcurrentThreads` controls what happens when multiple 
threads call `GetQueuedCompletionStatus`.  

But since a given instance of `IocpProactor` only calls 
`GetQueuedCompletionStatus` from a single thread, probably this arg doesn't 
matter, and the value `1` would be more explicit about the pattern asyncio is 
using?  A huge number is, presumably, either not relevant or, at worst, 
wasteful of some kernel resource.  

Am I correct that only one thread calls `GetQueuedCompletionStatus` on a given 
`iocp` object in asyncio under Windows `IocpProactor`?

[issue35580] Windows IocpProactor: CreateIoCompletionPort 4th arg 0xffffffff -- why is this value the default?

[Jeff Robbins]

New submission from Jeff Robbins :

By default, the __init__ function of IocpProactor in windows_events.py calls 
CreateIoCompletionPort with a 4th argument of 0x, yet MSDN doesn't 
document this as a valid argument.
https://docs.microsoft.com/en-us/windows/desktop/fileio/createiocompletionport

It looks like the 4th arg (NumberOfConcurrentThreads) is meant to be either a 
positive integer or 0.  0 is a special value meaning "If this parameter is 
zero, the system allows as many concurrently running threads as there are 
processors in the system."

Why does asyncio use 0x instead as the default value?

AES Encryption/Decryption

[Jeff M]

Python newbie here, looking for code samples for encrypting and decrypting 
functions, using AES.  See lots of stuff on the interwebs, but lots of comments 
back an forth about bugs, or implemented incorrect, etc...

I need to encrypt some strings that will be passed around in URL, and then also 
some PII data at rest.

Thanks.

[issue16038] ftplib: unlimited readline() from connection

[Jeff Dafoe]

Jeff Dafoe  added the comment:

I have a question about this old patch, as it just came down in a CentOS 6 
update. I think the patch is applied to the data channel in ASCII mode and not 
just the control channel. On the data channel in ASCII mode, there should be no 
assumption of maximum line length before EOL. I saw that your current value 
came from vsftpd's header file. I'm guessing if you look at the implementation, 
it's either only applied to the control channel or it's just used to set a 
single read size inside of a loop.  Examples of ASCII mode files that can 
exceed nearly any MAXLINE value without EOL are XML files or EDI files.

[issue33224] "RuntimeError: generator raised StopIteration" in difflib.mdiff

[Jeff Kaufman]

New submission from Jeff Kaufman <jeff.t.kauf...@gmail.com>:

With python built at HEAD (c51d8c9b) and at 3.7b3 (fcd4e03e08) the code:

import difflib
for fromdata, todata, flag in difflib._mdiff(
["2"], ["3"], 1):
  pass

produces:

Traceback (most recent call last):
  File "/home/jefftk/cpython/Lib/difflib.py", line 1638, in _mdiff
from_line, to_line, found_diff = next(line_pair_iterator)
StopIteration

The above exception was the direct cause of the following exception:

Traceback (most recent call last):
  File "/home/jefftk/icdiff/repro.py", line 3, in 
["2"], ["3"], 1):
RuntimeError: generator raised StopIteration

In python 3.5 and 3.6 I don't get an error.

This is probably due to https://bugs.python.org/issue32670 which implements PEP 
479, but I this this isn't supposed to happen in library code?

Before going deeper into writing scripts to manually install Python,
have you considered using a portable version such as WinPython [1]. It
has an option to register itself.

[1]: https://winpython.github.io

> 3. Add C:\python2.7\Lib and C:\python2.7\Lib\site-packages to PYTHONPATH

Did someone tell you to do that? If so, please tell them it's wrong.
PYTHONPATH should never include those directories. It takes precedence
over the standard library, so adding those directories will break
other versions of Python on the system.

[issue30256] Adding a SyncManager Queue proxy to a SyncManager dict or Namespace proxy raises an exception

[Jeff DuMonthier]

New submission from Jeff DuMonthier:

In multiprocessing, attempting to add a Queue proxy to a dict or Namespace 
proxy (all returned by the same SyncManager) raises an exception indicating a 
keyword argument 'manager_owned=True' has been passed to the function 
AutoProxy() but is not an argument of that function.

In lib/python3.6/multiprocessing/managers.py, in function RebuildProxy(), line 
873: "kwds['manager_owned'] = True" adds this argument to a keyword argument 
dictionary.  This function calls AutoProxy which has an argument list defined 
on lines 909-910 as:
def AutoProxy(token, serializer, manager=None, authkey=None,
  exposed=None, incref=True):
This raises an exception because there is no manager_owned argument defined.  I 
added "manager_owned=False" as a keyword argument to AutoProxy which seems to 
have fixed the problem.  There is no exception and I am able to pass Queue 
proxies through dict and Namespace proxies to other processes and use them.  I 
don't know the purpose of that argument though or if the AutoProxy function 
should actually use it for something.  My fix allows but ignores it.

Jeff Allen added the comment:

Just terminology ... strictly speaking what you've done here is "add a *field* 
to the nodes Module, FunctionDef and ClassDef", rather than add an *attribute* 
-- that is, when one is consistent with the terms used in the ast module 
(https://docs.python.org/3/library/ast.html#node-classes) or Wang

[issue29081] time.strptime() return wrong result

[Jeff Knupp]

Jeff Knupp added the comment:

I believe this is working as intended. Remember, the '%w' directive instructs 
strptime to consider 0 to be Sunday, while tm_wday considers 0 Monday. In 2016, 
the %W directive means that the first week (week #1) starts on Monday, January 
4th. If you go 52 weeks forward from the 4th, you get to Monday, December 26th. 
By asking for day 0 (%w=0), you want the *Sunday* of the 52nd week *from the 
first Monday of the year*. Since Monday is day 0 of that week, you want the 
Sunday that is 6 days from the 26th, or Jan 1, 2017.

One can certainly argue that tm_yday is documented to return an integer between 
[0,366] and thus we should never see 367, but it's the correct value given your 
input. The only other choice would be to raise an exception, which definitely 
shouldn't happen since the values you entered clearly match the format string 
spec.

Perhaps the docs should be updated, but when you consider that %W goes from 
[0,53], tm_yday can go well past 366 and still represent a semantically valid 
value.

[issue28730] __reduce__ not being called in dervied extension class from datetime.datetime

[Jeff Reback]

New submission from Jeff Reback:

xref to https://github.com/pandas-dev/pandas/issues/14679.

pandas has had a cython extension class to datetime.datetime for quite some 
time. A simple __reduce__ is defined.

def __reduce__(self):
object_state = self.value, self.freq, self.tzinfo
print(object_state)
return (Timestamp, object_state)

In 3.5.2:

Python 3.5.2 |Continuum Analytics, Inc.| (default, Jul  2 2016, 17:52:12) 
[GCC 4.2.1 Compatible Apple LLVM 4.2 (clang-425.0.28)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>> import pandas as pd
>>> import pickle
>>> pickle.dumps(pd.Timestamp('20130101'))
(13569984000, None, None)
b'\x80\x03cpandas.tslib\nTimestamp\nq\x00\x8a\x08\x00\x00\xc6\xe8\xda\x06\xd5\x12NN\x87q\x01Rq\x02.'

But in 3.6.03b

Python 3.6.0b3 | packaged by conda-forge | (default, Nov  2 2016, 03:28:12) 
[GCC 4.2.1 Compatible Apple LLVM 6.0 (clang-600.0.54)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>> import pandas as pd
>>> import pickle
>>> pickle.dumps(pd.Timestamp('20130101'))
b'\x80\x03cpandas.tslib\nTimestamp\nq\x00C\n\x07\xdd\x01\x01\x00\x00\x00\x00\x00\x00q\x01\x85q\x02Rq\x03.'


So it appears __reduce__ is no longer called at all (I tried defining 
__getstate__, __getnewargs__ as well, but to no avail). Instead it looks like 
datetime.datetime.__reduce__ (well a c function is actually called).

Link to the codebase.

[issue26040] Improve coverage and rigour of test.test_math

[Jeff Allen]

Jeff Allen added the comment:

Ah, cunning: I can make sense of it in hex.

>>> hex(to_ulps(expected))
'0x3ff0'
>>> hex(to_ulps(got))
'0x3fec'
>>> hex( to_ulps(got) - to_ulps(expected) )
'-0x4'

... and what you've done with ulp then follows.

In my version a format like "{:d} ulps" was a bad idea when the error was a 
gross one, but your to_ulps is only piece-wise linear -- large differences are 
compressed.

I'm pleased my work has mostly survived: here's hoping the house build-bots 
agree. erfc() is perhaps the last worry, but math & cmath  pass on my machine.

[Jeff Allen]

Jeff Allen added the comment:

Mark: Thanks for doing my homework. Points 1 and 3 I can readily agree with. I 
must take another look at to_ulps() with your patch on locally. I used the 
approach I did because I thought it was incorrect in exactly those corners 
where you prefer it. I'll take a closer look.

[issue26040] Improve coverage and rigour of test.test_math

[Jeff Allen]

Jeff Allen added the comment:

Mark: Thanks for validating the additional cases so carefully.

If you still want to apply it in stages then I suppose the change to the 
comparison logic could go first (untested idea), although that's also where I 
could most easily have made a mistake.

has the broader goal of becoming the most powerful and flexible open source
data analysis / manipulation tool available in any language.


*Highlights*:

   - .groupby(...) has been enhanced to provide convenient syntax when working
   with .rolling(..), .expanding(..) and .resample(..) per group, see here
   
<http://pandas.pydata.org/pandas-docs/version/0.18.1/whatsnew.html#whatsnew-0181-deferred-ops>
   - pd.to_datetime() has gained the ability to assemble dates from a
   DataFrame, see here
   
<http://pandas.pydata.org/pandas-docs/version/0.18.1/whatsnew.html#whatsnew-0181-enhancements-assembling>

I reread the thread. It was Mark. I mixed him up with the Thomas that was the

No, this was a different poster. And, thanks, Chris, for the email address. I

Certainly not, but as Random832 says, you can politely say No.

I realize there is no minimum requirement for social etiquette to be a good 
programmer. Or a bad one, for that matter. But if the purpose of this group is 
to help others with Python, simple courtesy seems to be common sense.

Ethan,

As a new member of this group, I am not sure on how to report unacceptable 
behavior. If this is not the correct way, I apologize.

Please check the following thread:

Find the number of robots needed to walk through the rectangular grid

I believe there was some unnecessary rudeness on the part of one of the 
respondants to the original post

Jeff Allen added the comment:

Thanks for the prompt acknowledgement and for accepting this to review.

I have updated the coverage & tolerance demo program. Usage in the comments (in 
v3).

I have also added the program I used to generate the extra test cases (needs 
mpmath -- easier to get working than mpf in the original Windows/Jython 
environment).

[issue26040] Improve coverage and rigour of test.test_math

[Jeff Allen]

Jeff Allen added the comment:

Here is a patch that improves coverage and addresses the uneven accuracy. 
Required accuracy is now specified in ulps. Mostly, I have choses 1 ulp, since 
this passed for me on an x86 architecture (and also ARM), but this may be too 
ambitious.

I have also responded to the comment relating to erfc:
# XXX Would be better to weaken this test only
# for large x, instead of for all x."

I found I could not contribute the code I used to generate the additional test 
cases in Tools/scripts without failing test_tools. (It complained of a missing 
dependency. The generator uses mpmath.)

ANN: pandas v0.18.0 Final released

[Jeff Reback]

Hi,

This is a major release from 0.17.1 and includes a small number of API
changes,
several new features, enhancements, and performance improvements along with
a
large number of bug fixes. We recommend that all users upgrade to this
version.

This was a release of 3.5 months with 381 commits by 100 authors
encompassing 465 issues and 290 pull-requests.

*What is it:*

*pandas* is a Python package providing fast, flexible, and expressive data
structures designed to make working with “relational” or “labeled” data both

the
broader goal of becoming the most powerful and flexible open source data
analysis / manipulation tool available in any language.

*Highlights*:

   - pandas >= 0.18.0 will no longer support compatibility with Python
   version 2.6 GH7718 <https://github.com/pydata/pandas/issues/7718> or
   version 3.3 GH11273 <https://github.com/pydata/pandas/issues/11273>
   - Moving and expanding window functions are now methods on Series and
   DataFrame similar to .groupby like objects, see here
   
<http://pandas.pydata.org/pandas-docs/version/0.18.0/whatsnew.html#whatsnew-0180-enhancements-moments>
   .
   - Adding support for a RangeIndex as a specialized form of the

<http://pandas.pydata.org/pandas-docs/version/0.18.0/whatsnew.html#whatsnew-0180-breaking-resample>
   - Removal of support for positional indexing with floats, which was
   deprecated since 0.14.0. This will now raise a TypeError, see here
   
<http://pandas.pydata.org/pandas-docs/version/0.18.0/whatsnew.html#whatsnew-0180-float-indexers>
   - The .to_xarray() function has been added for compatibility with the xarray
   package <http://xarray.pydata.org/en/stable/> see here
   
<http://pandas.pydata.org/pandas-docs/version/0.18.0/whatsnew.html#whatsnew-0180-enhancements-xarray>
   .
   - The read_sas() function has been enhanced to read sas7bdat files, see
   here
   
<http://pandas.pydata.org/pandas-docs/version/0.18.0/whatsnew.html#whatsnew-0180-enhancements-sas>

ANN: pandas v0.18.0rc1 - RELEASE CANDIDATE

[Jeff Reback]

Hi,

I'm pleased to announce the availability of the first release candidate of
Pandas 0.18.0.
Please try this RC and report any issues here: Pandas Issues
<https://github.com/pydata/pandas/issues>
We will be releasing officially in 1-2 weeks or so.

**RELEASE CANDIDATE 1**

This is a major release from 0.17.1 and includes a small number of API
changes, several new features,
enhancements, and performance improvements along with a large number of bug
fixes. We recommend that all
users upgrade to this version.

Highlights include:

   - pandas >= 0.18.0 will no longer support compatibility with Python
   version 2.6 GH7718 <https://github.com/pydata/pandas/issues/7718> or
   version 3.3 GH11273 <https://github.com/pydata/pandas/issues/11273>
   - Moving and expanding window functions are now methods on Series and
   DataFrame similar to .groupby like objects, see here
   
<http://pandas-docs.github.io/pandas-docs-travis/whatsnew.html#whatsnew-0180-enhancements-moments>
   .
   - Adding support for a RangeIndex as a specialized form of the
Int64Index for
   memory savings, see here
   
<http://pandas-docs.github.io/pandas-docs-travis/whatsnew.html#whatsnew-0180-enhancements-rangeindex>
   .
   - API breaking .resample changes to make it more .groupby like, see here
   
<http://pandas-docs.github.io/pandas-docs-travis/whatsnew.html#whatsnew-0180-breaking-resample>
   - Removal of support for positional indexing with floats, which was
   deprecated since 0.14.0. This will now raise a TypeError, see here
   
<http://pandas-docs.github.io/pandas-docs-travis/whatsnew.html#whatsnew-0180-float-indexers>
   - The .to_xarray() function has been added for compatibility with the xarray
   package <http://xarray.pydata.org/en/stable/> see here
   
<http://pandas-docs.github.io/pandas-docs-travis/whatsnew.html#whatsnew-0180-enhancements-xarray>
   .
   - Addition of the .str.extractall() method
   
<http://pandas-docs.github.io/pandas-docs-travis/whatsnew.html#whatsnew-0180-enhancements-extractall>,
   and API changes to the the .str.extract() method
   
<http://pandas-docs.github.io/pandas-docs-travis/whatsnew.html#whatsnew-0180-enhancements-extract>,
   and the .str.cat() method
   
<http://pandas-docs.github.io/pandas-docs-travis/whatsnew.html#whatsnew-0180-enhancements-strcat>
   - pd.test() top-level nose test runner is available GH4327
   <https://github.com/pydata/pandas/issues/4327>

See the Whatsnew
<http://pandas-docs.github.io/pandas-docs-travis/whatsnew.html> for much
more information.

Best way to get this is to install via conda
<http://pandas-docs.github.io/pandas-docs-travis/install.html#installing-pandas-with-anaconda>
from
our development channel. Builds for osx-64,linux-64,win-64 for Python 2.7
and Python 3.5 are all available.

conda install pandas=v0.18.0rc1 -c pandas

Thanks to all who made this release happen. It is a very large release!

[issue22121] IDLE should start with HOME as the initial working directory

[Jeff Allen]

Jeff Allen added the comment:

I'm also interested in a smooth experience for beginners.

I have a factual observation with respect to Terry's comment:
'''Windows icons have a Shortcut tab with a Start-in field.  We should like to 
put %USERPROFILE% there, but this does not work -- msg253393.'''
... I note that several menu shortcuts have "Start in" set to 
%HOMEDRIVE%%HOMEPATH%. Examples are notepad, Internet Explorer and the command 
prompt. (This is on Win7x64.) What we want seems to be a normal thing to do, 
and achieved by some, but perhaps by a post installation script.

Alternatively, once a .py file exists where you want to work, right-click "Edit 
with IDLE" provides the CWD we'd like best. Idea: add a New >> Python File 
context menu item. Encourage users to create a new file that way, then open it, 
and everything from there is smooth. (New issue if liked.)

[issue24725] test_socket testFDPassEmpty fails on OS X 10.11 DP with "Cannot allocate memory"

[Jeff Ramnani]

Jeff Ramnani added the comment:

I'm still getting these test failures on OS X 10.11.1.  Has a radar been filed 
with Apple?  I'd submit one, but I don't know enough about the issue to create 
a good bug report.

In the meantime, I'm attaching a patch to skip these tests as was done in issue 
#12958.

Re: Building a python extension on Windows

[Jeff Archer]

Ken,
I have been successful with building Python on Windows by
downloading Python-3.5.0.tgz.  Expand it and follow the instructions in
Python-3.5.0\PCBuild\readme.txt.  Basically, run get_externals.bat, then
use build.bat.  I have not however been successful building with VS2015
IDE.  Can't remember the specific issues off-hand but since I was
successful using the batch files, I didn't worry about it.
With this build of Python I have gotten rudimentary extensions working with
Boost.Python and straight C code.  Had to build Boost against this build of
Python to make that work.

Trying to build Python

[Jeff Archer]

I am trying to build Python on windows.  I have gotten the source in
compressed form, Python-3.5.0.tgz.  Attempting to follow PCBuild\readme.txt

Ran the get_externals.bat in the PCBuild folder.  No apparent errors.

Trying to build and getting errors:
1>  abort: there is no Mercurial repository here (.hg not found)
1>C:\Dev.ThirdParty\Python-3.5.0\PCbuild\pythoncore.vcxproj(403,5): warning
MSB3073: The command "hg id -b >

exited with code 255.
1>  abort: there is no Mercurial repository here (.hg not found)

Seems like this is indicating that I need to get the source from a
Mercurial repo to be able to built it.

Thanks for the help, Tim.
Sorry, I forgot to mention that I am trying to build debug.
I am running get_externals.bat as a separate step but I can't imagine this
is an issue.  I am mainly do it this way because ultimately I want to
build Debug/Release for 32/64 bit.

cd When I build from batch file these errors turn into
  The system cannot find the path specified.
  The system cannot find the path specified.
  The system cannot find the path specified.
Which is odd since hg is on the Path and I can reproduce the failures when
I run the command directly from the command prompt
C:\Dev.ThirdParty\Python_3_5_0\Python-3.5.0\Python-3.5.0\PCbuild>findonpath
hg.exe
C:\Program Files\TortoiseHg\hg.exe

C:\Dev.ThirdParty\Python_3_5_0\Python-3.5.0\Python-3.5.0\PCbuild>hg id -b
abort: there is no Mercurial repository here (.hg not found)


But I do get the expected binaries, I believe

Can you confirm that these are the expected binaries and correct file sizes?

Also, I have noticed that a file gets deleted by the build process
Python-3.5.0/Python-3.5.0/externals/openssl-1.0.2d/crypto/buildinf.h
Do you see this also?
