New submission from Michael Abbott <[EMAIL PROTECTED]>: The (undocumented!) API for PyOS_InputHook has two defects which are addressed in the attached patch (at least when using the readline module): firstly the called hook currently has to guess that input will come on descriptor 0; secondly, any Ctrl-C interrupts encountered during the processing of the input hook are lost.
This loss of interrupts can be rather annoying. The attached patch addresses these problems by redefining the API to PyOS_InputHook as int PyOS_InputHook(int file_in); where file_in is the descriptor to monitor (PyOS_InputHook need not return until file_in is ready to read), and the return value is non-zero if and only if processing was interrupted. Testing for interruption is implemented in the HAVE_RL_CALLBACK and HAVE_SELECT branch of Modules/readline.c; other uses retain their original functionality (I believe!). The attached patch was prepared against http://svn.python.org/projects/python/trunk , current at the time of writing. ---------- components: None files: input-hook.patch keywords: patch messages: 68638 nosy: Araneidae severity: normal status: open title: Interrupts are lost during readline PyOS_InputHook processing type: feature request versions: Python 2.6 Added file: http://bugs.python.org/file10709/input-hook.patch _______________________________________ Python tracker <[EMAIL PROTECTED]> <http://bugs.python.org/issue3180> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
