Message-ID: <w2rb54b34af1004010430l4bb8a642ya8a2a17a8acef35a@mail.gmail.com>

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,

Thanks for the notice, I'll fix this as soon as possible

commit f31fb2244f153f1e73739232cf31a6bb73307cfa
Author: Peter Keller <psilord at cs.wisc.edu>
Date:   Fri Apr 2 10:41:07 2010 -0500

    This is the initial revision of the tutorial and associated examples.
    The tutorial describes IPV4 TCP blocking and non-blocking I/O in addition
    to a couple of threaded examples. "tutorial.tmpl" is the source file used by
    "gen-tutorial" to create the atual "tutorial" file. Please see the README for
    more information.
    
    The autogenerated "tutorial" file is actually committed since it allows people
    who clone the repository to view the tutorial without having to know how to
    make it. This means if tutorial.tmpl or the examples are changed, the tutorial
    file should be regenerated and rechecked in.

Subject: [iolib-devel] IOLib tutorial Version 0.0 Completed
Message-ID: <20100404005033.GA1805@cs.wisc.edu>

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.

Hello,

I updated my clbuild copy of iolib with the last set of patches as current on
Sat Apr 10 14:05:19 CDT 2010 and got this build failure.

It looks like SHA a7674ea8a491cb4b3fd636e5952c3141611176da caused the error.

Thank you.

for the record, the related dojo bug report:
http://trac.dojotoolkit.org/ticket/10985

conclusion: browsers behave weird and different, but simply returning
an empty xml answer with a reverted iolib does not provoke the erratic
behavior i see with iolib head.

i've done a bit more experimenting and i have one more data point:
firebug in ff shows that the http request is running indefinitely long
(several minutes later the progress indicator still spinning), even
though the server log shows that handling the request have finished
(with a call to close in uwp and no sign or error). maybe the browser
does not receive the socket closed notification?

the console in chrome doesn't even show the xhr request being made, i
guess chrome only logs it after it has finished.

hth,

I've seen that exact error. My example programs will produce it.
Just start up ex6-server, connect with ex5a-client, type 'hello'
at the client prompt, then 'quit'. The client hangs around forever
while the server closed the connection.
