[issue43760] The DISPATCH() macro is not as efficient as it could be (move PyThreadState.use_tracing)
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. -- nosy: +jpe ___ Python tracker <https://bugs.python.org/issue43760> ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

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

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.

[issue14484] missing return in win32_kill?
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.

[issue5654] Add C hook in PyDict_SetItem for debuggers
John Ehresman added the comment: My hope is that the runtime performance cost will be negligible but if it isn't, it probably shouldn't go in. The issue with not putting it in another build is that many python debugger users won't want to recompile, so I see it as being of limited use if it's not in the default build. My experience with watchpoints in C debuggers (gdb) is they can be the difference between finding a bug and not -- I recall finding ref counting bugs only because I could watch the ref count and break on the code that modifies it. I would be willing to try and generalize this and support more hooks if there is some interest in it, though watching namespaces is probably the greatest payoff.

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.

[issue5654] Add C hook in PyDict_SetItem for debuggers
New submission from John Ehresman : 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. -- components: Interpreter Core files: dicthook.diff keywords: patch messages: 85051 nosy: jpe severity: normal status: open title: Add C hook in PyDict_SetItem for debuggers versions: Python 2.7 Added file: http://bugs.python.org/file13549/dicthook.diff ___ Python tracker <http://bugs.python.org/issue5654> ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

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.

John Ehresman added the comment: Latest version works -- question is why prior versions spawned many subprocesses. It's really another bug because prior version wasn't hitting the write length limit. -- title: multiprocessing.Pipe terminates with ERROR_NO_SYSTEM_RESOURCES if large data is sent (win2000) -> multiprocessing.Pipe terminates with ERROR_NO_SYSTEM_RESOURCES if large data is sent (win2000) ___ Python tracker <http://bugs.python.org/issue3551> ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue1706256] Give Partial the ability to skip positionals
John Ehresman 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. -- nosy: +jpe ___ Python tracker <http://bugs.python.org/issue1706256> ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue4018] "for me" installer problem on x64 Vista
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. ___ Python tracker <[EMAIL PROTECTED]> <http://bugs.python.org/issue4018> ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue4018] "for me" installer problem on x64 Vista
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. ___ Python tracker <[EMAIL PROTECTED]> <http://bugs.python.org/issue4018> ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

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