| There are a handful of outstanding asyncore/asynchat related bugs in the tracker. This patch seeks to handle all of the issues with the exception of windows-specific socket errors from 658749 . In particular, it takes pieces of patches 909005 and 1736101, to address some issues raised there, as well as the bugs: 539444, 760475, 777588, 889153, 953599, 1025525, and 1063924. In some cases where it could potentially handle fewer exceptions (see the send method), I have opted to handle more of them due to testing actually producing them. It adds test cases from patch 909005. It adds two new sample methods to asynchat.async_chat _get_data and _collect_incoming_data to be used as examples for handling incoming buffers. It removes the simple_producer and fifo classes from asynchat, but accepts work-alikes to the asynchat.async_chat.push_with_producer method. It further fixes an unreported violated invariant in asynchat.async_chat.handle_read() . It also produces a useful error message when asyncore.dispatcher.handle_expt_evt is called if the base handle_expt has not been overwritten. This patch should be applied to the trunk. The new methods, and removal of the two classes should not be included in patches to 2.5 maintenance (don't add the methods and don't remove the classes). Basically everything else should work as it did before (with better error handling), unless someone was monkey-patching asyncore.dispatcher.handle_expt . |

| Good work. I would only rencommend to include documentation for asyncore.close_all function, actually not documented yet. |

| This patch removes two public--and documented--classes from asynchat (simple_producer and fifo). Even if the proposed changes to asynchat make them utterly worthless, I thought it was general policy to deprecate public items for a release or two before removing them. Is this the case even when they're as simple as these two classes? |

| We can leave those two classes in, even though I have never seen them used or subclassed. In Python 3.x, we can remove them without issue. |

| The current implementation of asynchat.async_chat.initiate_send method doesn't look at what is specified in ac_out_buffer_size attribute which represents the buffer size of the outgoing data defaulting to a maximum of 4096 bytes to send in a single socket.send() call. Note that this only happens when sending the data by using a producer through the use of the push_with_producer method. This happens because while the older asynchat version used slicing for buffering: > num_sent = self.send(self.ac_out_buffer[:obs]) # obs == ac_out_buffer_size ...the newer version just calls self.send using the entire data as argument without caring of what ac_out_buffer_size thinks about it: > num_sent = self.send(first) What is specified in ac_out_buffer_size when using a producer is just ignored and the only way to have control over the outgoing data buffer is to operate directly on the producer. |

| In attachment I provide a patch for fixing this last mentioned issue. It's a rewriting of initiate_send method which now looks at what is specified by ac_out_buffer_size attribute. |

| I've discussed a lot with Josiah via e-mail and this is the updated version of the patch including a fix for the two issues raised before. This update has been needed also because the original patch has been out-dated by some commits after r53734 involving the test suite and the documentation, which I both took off this patch. I also re-added simple_producer and fifo classes in asynchat.py since it seems they are needed for passing tests. The test suite has passed on Windows XP using Python 2.6 alpha 1. I have also successfully run the test suite of a project of mine based on asynchat which includes over 40 tests. |

| In attachment the Josiah Carlson's patch who currently seems to have problems in accessing the bug tracker. It should address all the problems raised on python-dev related discussion: http://groups.google.com/group/python-dev2/browse_thread/thread/eec1ddadefe09fd8/40e79742231076b9?lnk=gst&q=asyncore#40e79742231076b9 |
