High Priority Windows API Functions, Structures and Constants

[opalmer]

This issue covers a list of Windows API functions which Twisted and other projects are currently using. This issue is really meant to be a TODO list of sorts to keep track of remaining work to be done.

Functions

• GetOverlappedResult() - GetOverlappedResult implementation #115
• ClearCommError() - Implement ClearCommError #79
• CloseHandle() - Create pywincffi.kernel32.handle module #50
• CreatePipe() - Refactor kernel32 Module Structure #53
• CreateProcess() - Implement CreateProcess #98
• CreateEvent() - Implement CreateEvent #70
• DuplicateHandle() Implement DuplicateHandle #78
• GetCurrentProcess() - Implement GetProcessId() and GetCurrentProcess() #49
• GetExitCodeProcess() - Implement pid_exists() #48
• GetHandleInformation() - Adding GetHandleInformation and SetHandleInformation #66
• GetStdHandle() - Create pywincffi.kernel32.handle module #50
• MsgWaitForMultipleObjects() - Implement MsgWaitForMultipleObjects #80
• PeekNamedPipe() - Refactor kernel32 Module Structure #53
• ResetEvent() - Implement ResetEvent #75
• ReadFile() - Anonymous Pipes #9
• SetNamedPipeHandleState() - Refactor kernel32 Module Structure #53
• TerminateProcess() Implement TerminateProcess #76
• WriteFile() - Anonymous Pipes #9
• WaitForSingleObject() - Implement pid_exists() #48
• WSAEventSelect() - Implement WSAEventSelect and WSAEnumNetworkEvents #81
• WSAEnumNetworkEvents() - Implement WSAEventSelect and WSAEnumNetworkEvents #81

Structures

• SECURITY_ATTRIBUTES - Anonymous Pipes #9
• STARTUPINFO - Implement _STARTUPINFO and associated contants #74
• OVERLAPPED - Anonymous Pipes #9

Constants

• STARTF_USESTDHANDLES - Implement _STARTUPINFO and associated contants #74
• DUPLICATE_SAME_ACCESS - Implement DuplicateHandle #78
• STD_OUTPUT_HANDLE - Support for twisted.python.lockfile #18
• FD_ACCEPT - Implement WSAEventSelect and WSAEnumNetworkEvents #81
• FD_CLOSE - Implement WSAEventSelect and WSAEnumNetworkEvents #81
• FD_CONNECT - Implement WSAEventSelect and WSAEnumNetworkEvents #81
• FOREGROUND_RED - Implement FOREGROUD_* colors #95
• FOREGROUND_GREEN - Implement FOREGROUD_* colors #95
• FOREGROUND_BLUE - Implement FOREGROUD_* colors #95
• PIPE_NOWAIT - Pipe Enhancements #16
• QS_ALLINPUT - Implement MsgWaitForMultipleObjects #80
• WAIT_OBJECT_0 - Implement pid_exists() #48
• WAIT_TIMEOUT - Implement pid_exists() #48

Excluded
The following are excluded from conversion because the surrounding code in Twisted was deprecated or other methods of performing the same task are available.

• FormatMessage - cffi handles this
• RegOpenKeyEx - Surrounding code was deprecated
• RegQueryValueEx - Surrounding code was deprecated

NOTE: The actual list of functions may be longer than the above. The calls are just those that are used directly. More may be required in order to properly test pywincffi's implementation.

Oliver, I'm doing progress in the implementation of GetOverlappedResult... Checkout https://github.com/exvito/pywincffi/tree/get-ov-result

Most code is in place, just wrapping my head around the best way to test it. There is something there, still not working.

I'm off to the airport now to fly back to Lisbon. I expect to be able to get back to it later this week.

Cheers.

Sounds good, thanks for the heads up and the help as always.

In terms of testing, looks like what you have may be a pretty good start. Usually when I find it difficult to come up with a test I look to the MSDN docs for examples and go from there.

I'm confused as to the state of this ticket wrt being a TODO list. Are there items still remaining for this (and the project getting beta status) that are not mentioned in the ticket?

[opalmer]

Nope there's not anything remaining....I just never got around to closed the issue. Basically I was using this issue to track the major functions necessary in order to use pywincffi to replace pywin32 in twisted. With respect to beta status, the project is probably at that stage now considering the APIs and practices in pywincffi are unlikely to be changing.
