[iolib-devel] regression after 6d63d32fb7f400e93066cb37a139a43dae4721c1
by Attila Lendvai 28 May '10

28 May '10

hi! seems like something was broken by one of the two patches that follow this one: 6d63d32fb7f400e93066cb37a139a43dae4721c1 "Remove useless check in MAYBE-REWIND-IOBUF." i don't know which one, because the second newest patch doesn't work on its own due to a not of type function error. the symptom is that in some cases the ajax answers in our web server doesn't arrive to the browser, the network stream seems to be closed. i suspect some bug around flushing? stuff mostly work, but there's a reproducible call site (so, it's not a heisenbug) where the answer body is lost (the headers are properly sent though). the body is written using write-sequence as a byte array. hth, -- attila

[iolib-devel] Introductory tcp client/server examples
by Peter Keller 14 May '10

14 May '10

Hello, I've been writing a tutorial for how to use IOLib loosely following the second edition of the unix network programming book by Richard Stevens. Attached to this mail is a tarball of a collection of example programs I've written which illustrate certain concepts in using IOLib. It is intended that this tutorial go all the way from the simple iterative daytime server example, all the way to nonblocking and multiplexed network i/o for a server with many clients. I am not finished with this work at all (such as the tutorial is simply an outline and I only have a small collection of example programs!), but Stelian wanted to see examples of the code I had written and thought the list would be a good place for it. Thank you. -pete

[iolib-devel] PATCH: with-accept-connection and shutdown

[iolib-devel] IOLib tutorial Version 0.0 Completed
by Peter Keller 04 Apr '10

04 Apr '10

Hello, I've created an IOLib tutorial which describes how to write clients and servers with IPV4 TCP using blocking I/O with the stream interface and nonblocking I/O with the event multiplexer and send-to receive-from. The tutorial and the source for which it is written is in the examples/ directory of the checked out IOLib source codes. The tutorial and source code in the official source release of IOLib will always be the authoritative version. It is recommended one inspects and tries out the example source code along with the tutorial. I happen to have a link up to the tutorial here: http://pages.cs.wisc.edu/~psilord/blog/data/iolib-tutorial/tutorial.html Have a nice day. -pete
