[Python-Dev] PEP 3145

Hello all, I have been working on adding asynchronous I/O to the Python subprocess module as part of my Google Summer of Code project. Now that I have finished documenting and pruning the code, I present PEP 3145 for its inclusion into the Python core code. Any and all feedback on the PEP (http://

[Python-Dev] PEP Submission

Several days ago, around the time the python.org servers went down, I submitted a PEP to edi...@python.org. When things to have been worked, I submitted the PEP again. I have not seen any activity on the PEP in Python-Dev or any reply acknowledging that it was received. Did I misunderstand the proc

Re: [Python-Dev] (try-except) conditional expression similar to (if-else) conditional (PEP 308)

What about catching specific error numbers? Maybe an option so that the dictionary elements can also be dictionaries with integers as the keys: filedata = try_3(open, randomfile, except = { IOError, {2: None} } ) If it isn't found in the dictionary, then we raise the error. On Thu, Aug 6, 2

[Python-Dev] Functionality in subprocess.Popen.terminate()

In my GSoC project, I have implemented asnychronous I/O in subprocess.Popen. Since the read/write operations are asynchronous, the program may have already exited by the time one calls the asyncread function I have implemented. While it returns the data just fine, I have come across an issue with t

Re: [Python-Dev] Implementing File Modes

My motivation came from an instance when I was using subprocess.Popen for a Linux / Windows cross platform program. In part of the program, I was writing and reading to a cron like object. On Windows, it was a text file and on Linux it would be the crontab executable. Had I been able to substitute

[Python-Dev] Implementing File Modes

Hello, Since there was a bit of confusion last time, I'll start by saying I am working on the subprocess.Popen module for Google Summer of Code. One of the features I am implementing is a class so that a running process can stand in in place of a file. For examples, instead of open( "filelist", mo

[Python-Dev] Replacing PyWin32's PeekNamedPipe, ReadFile, and WriteFile

Hello, I have written replacements for a few of Mark Hammond's PyWin32 functions using ctypes to call upon the Windows kernel API. Code can be found here; http://pastebin.com/m46de01f . When calling ReadFile, it appears that the kernel API converts '/n' newlines '/r/n' newlines. I have not been ab

[Python-Dev] Popen asynchronous input for Windows

Hello, I am looking for alternatives to Josiah Carlson's asynchronous I/O patch for subprocess.Popen. While his patch seems to work well, it relies on pywin32 which is not part of the standard Python library. If I cannot find an alternative, I will be using cTypes with the parts of Mark Hammond's
