Re: [Libevent-users] filter bufferevents and timeout

[Bruno CARLUS <b.carlus@xxxxxxxxxxxxx>]

Thank you Azat.

So I ran my test code with Libevent version (2.2.0-alpha-dev):
it seems that there is no difference because the call to bufferevent_flush triggers filter cb but still not read cb.

Concerning evbuffer, you mean using evbuffer_remove with a data_ptr refencing the mmaped file ?
That's what i'm doing from inside the read cb

So could you try next patch please?
  https://github.com/azat/libevent/commit/ed38bfb4ea46e3a53c0dba0c7cabd0dfbd30f047.patch

Or, if you need the whole tree:
  https://github.com/azat/libevent.git be-filter-watermarks

(It is just a WIP, I will rebase it later).

Why not just using evbuffer for this?
