[Libevent-users] 14k vprintf evbuffer on solaris

[Michael Herf <herf@xxxxxxxxx>]

I'm compiling libevent-2.0.7-rc on my Linux and OpenSolaris box. I'm 
seeing a bug that happens on OpenSolaris only.

When I make an evbuffer and call "evbuffer_add_vprintf" to add more than 
~14k to it (many small writes, few bytes at a time), the Solaris version 
of the code fails and sends 0 bytes. (evbuffer_get_length() reports the 
correct number, but evhttp_send_reply() sends nothing.)

The Linux version works fine, and sending larger blocks on Solaris via 
"evbuffer_add()" works fine too (as do smaller buffers using 
evbuffer_add_vprintf).

Has anyone else seen a failure case like this? (I'm going to dig in and 
see what I can find.)

Currently I'm using evhttp to respond to http requests. I make a new 
evbuffer, and then send with evhttp_send_reply.
This server has been "stable" for quite a while, until the recent 
upgrade to 2.0.7-rc (was using 2.0.1 earlier).
