[issue43760] The DISPATCH() macro is not as efficient as it could be (move PyThreadState.use_tracing)

2021-09-20 Thread John Ehresman


John Ehresman  added the comment:

Is adding the field back an option at this point? It would mean that extensions 
compiled against the release candidates may not be binary compatible with the 
final release

My take is that use_tracing is an implementation and version dependent field, 
and that binary compatibility will be maintained for a specific release (e.g. 
3.10) but that there's no assurance that it will be there in the next release 
-- though these things tend not to change. I also regard generated cython code 
as only being valid for the releases that a specific cython version supports.

Code and API's change slowly, but eventually they do change.

[issue23948] Deprecate os.kill() on Windows

2021-03-20 Thread John Ehresman


John Ehresman  added the comment:

The original idea was to not use kill on win32 because developers often assume 
it will work like it does on unix-like OS's -- my claim is while kill could be 
improved on win32, it still won't support all the things kill can do elsewhere. 
 

I don't think this idea has much, if any support so I suggest closing this bug 
and opening other specific bugs to improve it on win32 for the ideas mentioned 
in the comments.

[issue42080] Disutils on windows debug build fails without -j1

2020-10-19 Thread John Ehresman


New submission from John Ehresman :

Compiling pillow for a debug build fails without -j1 because distutils 
parallelizes the build, but there are problems with locking the .pdb file 
during when compiling the C files.  An example of the error message from a 
cl.exe command is:

fatal error C1041: cannot open program database 
'C:\src\tmp\pillow-test\Pillow-7.2.0\vc140.pdb'; if multiple CL.EXE write to 
the same .PDB file, please use /FS

Building works with setup.py build_ext --disable-jpeg --disable-tiff 
--disable-zlib --debug build -j1

My guess is the fix is not to parallelize by default in a debug build; a /FS 
arg to cl.exe could be used, but that doesn't seem to be recommended.

I realize this might be considered a pillow bug, but my guess is that it 
affects other packages as well

[issue28521] _PyEval_RequestCodeExtraIndex should return a globally valid index, not a ThreadState specific one

2016-10-24 Thread John Ehresman

New submission from John Ehresman:

The index returned by _PyEval_RequestCodeExtraIndex is currently specific to 
the current thread state.  This means that there will be problems if the index 
is used on another thread.  It would be possible to set things up in my code so 
that _PyEval_RequestCodeExtraIndex was called once per thread state but there 
would be a possibility of getting different indices on the different threads 
and data set on one thread passed to the wrong free function registered on a 
different thread.

[issue27286] str object got multiple values for keyword argument

2016-08-10 Thread John Ehresman

John Ehresman added the comment:

Should the bytecode magic number be bumped in the 3.5 branch?  This breaks .pyc 
/ .pyo binary compatibility for python 3.5.  As far as I can tell this has 
never been done before in a release after the major.minor.0 final release.

This patch has made its way into debian's python 3.5 and I've gotten a bug 
report because of it for an app distributed without python source.

Looking at the 3.5.2 tarball, it does not look like the change was included in 
3.5.2.  If the magic number is bumped in 3.5, the comment should be changed to 
reflect that it changes in 3.5.3 and not in 3.5.2

[issue23948] Deprecate os.kill() on Windows

2015-04-15 Thread John Ehresman

John Ehresman added the comment:

Part of the issue here is that GenerateConsoleCtrlEvent doesn't work like kill 
w/ SIGINT does on unix -- it only works if the the target process id is 0 and 
then it generates the signal in all processes that share the console.  An 
alternate proposal here is to expose the GenerateConsoleCtrlEvent functionality 
separately and only accept a signal number of 9 and maybe 0 in kill().

John Ehresman added the comment:

Interesting -- I didn't know about removing the ignore flag in the child 
process.  The question is whether this is close enough to the kill w/ SIGINT 
behavior on unix to use the same name.  I think that there are enough 
differences to warrant a Windows specific function that calls 
GenerateConsoleCtrlEvent.

[issue23948] Deprecate os.kill() on Windows

2015-04-14 Thread John Ehresman

New submission from John Ehresman:

os.kill() on Windows cannot act like it does on non-windows platforms because 
of differences in the underlying platforms.  I think only kill() with a signal 
number of 9 (terminate process unconditionally) and a signal number of 0 (test 
to see if process exists) could be implemented.  It isn't possibly to send the 
INT signal or a HUP signal to another process -- or at least it isn't possible 
without the use of questionable api's and code.

Windows specific functions would be added for terminateprocess() and 
generateconsolectrlevent().  os.kill() on non-windows platforms would be left 
alone.

I've created issue #23948 for the idea of deprecating os.kill().

Is a patch needed for adding a return in the error case?  It's that way in 2.7

than strict backward compatibility.

[issue14484] missing return in win32_kill?

2015-04-13 Thread John Ehresman

John Ehresman added the comment:

I think at a minimum, a return should be added in the cases that call 
GenerateConsoleCtrlEvent and it fails.

Here's a more radical proposal, though: deprecate kill() on Windows and add a 
function that calls GenerateConsoleCtrlEvent and another that calls 
TerminateProcess.  The rationale is that the two do act quite a bit differently 
than kill does on non-Windows systems do and it's a bad idea to try to provide 
cross-platform functionality when it can't be done.  kill() on non-Windows 
systems would be left alone.

[issue23719] PEP 475: port test_eintr to Windows

2015-04-13 Thread John Ehresman

John Ehresman added the comment:

Here's the 1st draft of a test for interrupts during time.sleep().  It creates 
a thread to generate the ctrl-c events which seems to work well (note that 
kill() on win32 is quite limited in terms of sending events to other 
processes).  The creation and use of the subthread probably could be improved.  
I also needed to add a way of specifying creationflags for a subprocess so a 
new console could be created; otherwise the parent test process is also 
interrupted by the ctrl-c.

I have not tested the modified test on a non-win32 platform

[issue14484] missing return in win32_kill?

2015-04-13 Thread John Ehresman

John Ehresman added the comment:

A problem with os.kill with CTRL_C_EVENT is that CTRL_C_EVENT == 0 and on unix 
kill w/ a signal number of 0 is how you test to see if a process is running.  
This means that code written on unix to see if a process exists will try to 
send a ctrl-c to the other process; it will fail because 
GenerateConsoleCtrlEvent is so limited but the error message is likely to be 
confusing.

Not using the kill() name also means that developers coming from unix won't 
expect other signal numbers to work.

[issue17723] Use FileRead and FileWrite in fileio.c on Windows

2013-04-13 Thread John Ehresman

New submission from John Ehresman:

File object's can use the win32 api FileRead and FileWrite instead of the CRT's 
read  write function.  This would eliminate the need to set the mode to binary 
on stdin  stdout, which is the underlying cause of issue 16587.  This could 
also possibly be the basis of adding nonblocking functionality.  An initial 
patch is attached, but I still need to verify what this does to the CRT mode of 
files that are opened by python (rather than already be opened, like stdin  
stdout are).

John Ehresman added the comment:

One way to fix this is to use the FileRead  FileWrite api functions directly 
as proposed in issue 17723  I would regard this as a change in behavior and not 
a simple bug fix because there is probably code written for 3.3 that assumes 
the C level stdout is in binary after python is initialized so would target 3.4 
for the change.

Attached is a short test file to demonstrate this.  It assumes the

[issue14302] Move python.exe to bin/

2012-03-20 Thread John Ehresman

John Ehresman j...@wingware.com added the comment:

Just a few thoughts from someone who uses Windows and who'd need to change code 
for this change:

1) I don't know if waiting to 3.5 is needed.  I can make the change to look in 
the bin directory fairly quickly.

2) Is it safe to add scripts to the PATH?  I'd worry about something in there 
that's named so it clashes with a standard program such as notepad or chkdsk or 
more likely something else from another 3rd party program that is installed.

3) A python3.3.exe command should be added so that if someone installs both 3.3 
and an eventual 3.4, he or she can run both.

4) The uninstaller should remove the PATH entry if at all possible.

Another alternative is to provide a Start menu item for a Python 3.4 Command 
Prompt that would set up the environment that's similar to the Visual Studio 
2008 Command Prompt.

[issue5654] Add C hook in PyDict_SetItem for debuggers

2009-04-01 Thread John Ehresman

New submission from John Ehresman j...@wingware.com:

I'm interested in adding support for debugger watchpoint's in the core.
 A watchpoint would cause the debugger to stop when a value in a
namespace changes.  This hook would be called when PyDict_SetItem 
PyDict_DelItem is invoked.  I realize that this does not cover function
local variables, but I'm more interested in instance attributes and globals.

This is a proof of concept patch; I wanted to see if it would work and
get some initial feedback.  I think the performance implications are
minimal in the case where nothing is watched, though the performance of
sample callback in _debuggerhooks can be improved.  An issue may be if
this is used outside a debugger implementation to implement an observer
pattern -- I'd like to discourage it, but worry that it will be used
since it's there, rather like how the settrace tracer gets used.

If there's interest in this, I will clean this up and add watchpoints to
pdb.

[issue3551] multiprocessing.Pipe terminates with ERROR_NO_SYSTEM_RESOURCES if large data is sent (win2000)

2009-04-01 Thread John Ehresman

John Ehresman j...@wingware.com added the comment:

Looking into this a bit more and reading the documentation (sorry, I 
picked this up because I know something about win32 and not because I 
know multiprocessing), it looks like a connection is supposed to be 
message oriented and not byte oriented so that a recv() should return 
what is sent in a single send().  This is like how Queue works in the 
threading case.  Note that I think the method signature when using the 
dummy.connection differ when using pipe_connection and that the two 
differ in what happens when several send_bytes's occur before a recv_bytes

I'm currently leaning toward essentially leaving the current behavior 
(and documenting it) though maybe with a better exception and 
documenting that large byte arrays can't be sent through the pipe. 
What's still an issue is if a pickle ends up being too large.

2009-04-01 Thread John Ehresman

John Ehresman j...@wingware.com added the comment:

New patch which raises ValueError if WriteFile fails with
ERROR_NO_SYSTEM_RESOURCES.  I wasn't able to reliably write a test since
putting the send_bytes in a try block seems to allow the call succeed. 
This is probably OS, swap file size, and timing dependent.

[issue3551] multiprocessing.Pipe terminates with ERROR_NO_SYSTEM_RESOURCES if large data is sent (win2000)

2009-03-31 Thread John Ehresman

John Ehresman j...@wingware.com added the comment:

Attached is a patch, though I have mixed feelings about it.  The OS
error can still occur even if a smaller amount is written in each
WriteFile call; I think an internal OS buffer fills up and the error is
returned if that buffer is full because the other process hasn't read
yet.  The patch just ignores ERROR_NO_SYSTEM_RESOURCES and writes again.
 I don't know though if ERROR_NO_SYSTEM_RESOURCES can mean something
else is wrong and the write will never succeed.  The message is also
broken up into 32K parts and a recv_bytes on the other end must be
called multiple times to read it all.

The patch is one option.  Another might be to let the application decide
to continue or not and essentially treat the pipes as nonblocking.

Latest version works -- question is why prior versions spawned many

It turns out that the original reproduce.py deadlocks if the pipe buffer

[issue1706256] Give Partial the ability to skip positionals

2009-02-03 Thread John Ehresman

John Ehresman j...@wingware.com added the comment:

Commenting because this was brought up on python-dev -- I'd like this,
primarily for the string method  itertools optimization.  It's ugly,
but it would be better than writing C code.  The alternative might be to
somehow optimize trivial functions to execute without bytecode, but that
would be considerably harder.

[issue4018] for me installer problem on x64 Vista

2008-10-02 Thread John Ehresman

New submission from John Ehresman [EMAIL PROTECTED]:

After installing the 32 bit .msi or the 64 bit .msi for me on a fairly
clean Vista x64 machine, the socket module won't import because of a
side-by-side configuration error.  The output below is from the 32 bit
build.

Changing ../msvcr90.dll to ..\msvcr90.dll does not fix the problem

Importing socket does work when the msi is installed for everyone.

[issue4018] for me installer problem on x64 Vista

2008-10-02 Thread John Ehresman

John Ehresman [EMAIL PROTECTED] added the comment:

I think one of the tested machines is Vista RTM, though it's been 
updated.  I also tried of Vista x32 SP1 and it fails there.

If non-admin installs can't be made to work, I agree that the for me 
option be dropped and the installer changed to invoke UAC.  I looked for 
a solution to this, but so far can't find any -- and this would also 
mean that .pyd files in site-packages and elsewhere would need .manifest 
files that contain the path to where msvcr90.dll is located.  I think 
requiring an admin install might cause problems for py2exe though.

This is rather important because it means that python is unusable using 
the default installation options and I suspect that many users won't 
know how to install for everyone.

I'd still like to see the need to depend on a C runtime dll dropped at 
some point in the future, but I know that it's not an easy thing to do.

[issue4018] for me installer problem on x64 Vista

2008-10-02 Thread John Ehresman

John Ehresman [EMAIL PROTECTED] added the comment:

 I don't think this could even work: apparently, Vista disallows putting
 a path into the name field. So extension modules will have to ship with
 their own copy of the CRT (or link statically).

I agree that this is the case.  The closest thing I found to 
documentation of this is 
http://msdn.microsoft.com/en-us/library/ms235291.aspx under Deploying 
Visual C++ library DLLs as private assemblies.  It specifies that the 
assembly be copied twice, once into the folder with the .exe and again 
into the folder with the .dll.

I think the best option is to always install for everyone as 
administrator on Vista.

[issue3887] Python 2.6 doesn't run after installation on amd64

2008-09-18 Thread John Ehresman

John Ehresman [EMAIL PROTECTED] added the comment:

This is on a fresh Vista Ultimate install.  There is no msvcr90.dll
anywhere on the system, if windows file search according to windows file
search (I did check the hidden / system file box).

The first report is from a for me install.  After installing for all
users, there's no dll in \python26 and the error log error message of:
Activation context generation failed for C:\Python26\python.exe.
Dependent Assembly
Microsoft.VC90.CRT,processorArchitecture=amd64,publicKeyToken=1fc8b3b9a1e18e3b,type=win32,version=9.0.21022.8
could not be found. Please use sxstrace.exe for detailed diagnosis.

I tried using changing the .manifest and got a null pointer access error:
Faulting application python.exe, version 0.0.0.0, time stamp 0x48cb6bcf,
faulting module ntdll.dll, version 6.0.6001.18000, time stamp

process id 0xa28, application start time 0x01c919c8f9746f89.

I wonder if the x86 dll is being installed rather than the amd64 one.
