[16:22] <nickmbailey> jimbaker: so we are still seeing some potential issues even with the fix on that ticket
[16:22] <nickmbailey> specifically right now we're only seeing a problem on centos boxes
[16:23] <nickmbailey> i wonder if maybe bytesBeforeUnwritable() isn't accurate in certain situations

[17:11] <nickmbailey> actually it isn't just centos
[17:11] <nickmbailey> somehow it still seems like things are always guaranteed to be flushed

[19:21] <nickmbailey> jimbaker: we're still seeing the same issue we were seeing before. just somewhat less frequently
[19:22] <nickmbailey> the issue being that the server closes it's connection too early before the client has read everything

[20:08] <topi`> nickmbailey: maybe something about the TCP protocol semantics?
[20:08] <topi`> but, maybe not, the server can close the socket immediately after the socket has been established
[20:09] <topi`> then you'd see a FIN_WAIT state with netstat, for a while

[20:36] * TomA (~TomA@c-68-32-46-223.hsd1.mi.comcast.net) Quit (Ping timeout: 265 seconds)
[20:36] <nickmbailey> well the problem is in netty itself i think. we're closing the netty channel before netty has flushed everything to the underlying socket
[20:36] * TomA (~TomA@c-68-32-46-223.hsd1.mi.comcast.net) has joined #jython
[20:37] <nickmbailey> if i limit the buffer of any call to send() to 8192 bytes things seem to work...
[21:18] <jimbaker> nickmbailey, well that's a possible workaround
[21:19] <jimbaker> and compatible with send semantics guarantees
[21:31] <nickmbailey> yeah i'm slightly worried about performance implications
[21:31] <nickmbailey> but maybe that would work for a short term fix
[21:33] <jimbaker> nickmbailey, in my experience it's sending 2 bytes at a time that tends to be a problem, not 8192 bytes :)
[21:33] <nickmbailey> haha
[21:35] * TomA (~TomA@c-68-32-46-223.hsd1.mi.comcast.net) Quit (Remote host closed the connection)
[22:00] <nickmbailey> well this is the workaround that seems to be doing slightly better https://github.com/riptano/jython/pull/8/commits/b914e4d47169a99c59393e85490c7d850e879e07
[22:03] <nickmbailey> i came up with the 8192 number because that's how much data our client's we're trying to read and failing
[22:03] <nickmbailey> and also it's a default at least a few places in the netty codebase
[22:04] <nickmbailey> so that's about a half step past "pulled it out of a magic hat"
[22:13] <jimbaker> nickmbailey, yeah, it's a very reasonable number
[22:13] <jimbaker> and an easy workaround if it works out well in your testing
[22:13] <nickmbailey> yeah its actually the default page size in an internal buffer allocator i guess? http://netty.io/4.1/xref/io/netty/buffer/PooledByteBufAllocator.html
[22:14] <nickmbailey> so perhaps there is some sort of race with flushing whole pages of buffers or something
