Greetings,
Attached is a small patch which allows a user to grab the underlying
event_base from an evhttp_request. I have patched this against the
current master on github.
If there is a better way to do this, I am open to suggestions.
Thanks in advance!
http.c|9 +
This is an odd question that hopefully someone can help me out with. I
have a function right now that looks a bit like this:
void
read_data(struct bufferevent *bev, void *args) {
evbuffer *data;
data = bufferevent_get_input(bev)
if (evbuffer_get_length(data) < some_size) {

One of the ways nginx deals with very large streams of data is to
actually spool the data to file. By default this is turned off. But
this may be a simple solution to all of these problems.
The spooling is tra

compatible with bsd).

I have created a new project called libevhtp, a server-only replacement
for the current libevent http API. The API utilizes a streaming http
parser, which allows me to hook into a lot of places.
You can treat the API just like you would normal evhttp_* calls, but
instead use evhtp_*.

As an FYI, Libevent already does a good job of keeping track of all

If I grok this correctly, you are asking whether you can get a list of

Greetings all,
I have recently come across a pretty nasty issue using the
bufferevent_openssl API where my read callback would be executed more

My employer always avoids trying to re-invent the wheel when it comes to

Use evthread_use_pthreads() before anything else and compile with
