By default, when a bufferevent_socket_new type function is called, the only
flags that are set is BEV_OPT_CLOSE_ON_FREE. This function allows a user to
set their own flags.
* evhtp_send_reply_end bugfix: evhtp_send_reply_end() would set the request as
finished and then call bufferevent_flush(). The assumption here was bufferevent_flush()
actually does something, which in reality isn't the case:
bufferevent_sock = be_socket_flush(...) { return 0; }
bufferevent_openssl = be_openssl_flush(...) { return 0; }
My dumb expectation was the writecb would get called on a flush, so instead
send_reply_end() will now call the writecb directly (this function makes sure
all data has been sent and the request is finished, etc).
* _evhtp_accept_cb() will now check the return status of evthr_pool_defer, which
may return a RETRY. In this case it is assumed that the evthr is way too busy
and will drop the connection. In the future we may want to create a retry
mechanism to avoid dropped connections. Reasoning for this is if a evthr_defer
fails, a connection will be in limbo, and never accepted().
* Fixed minor bug in the http parser for reply status code errors.
* Made evhtp_unset_hook() public.
* Made evhtp_unset_all_hooks() public.
- Added optional OpenSSL support (with optional threading abstractions).
* In order to properly enable SSL for your server two things must happen:
evhtp_ssl_cfg structure must be filled with your settings:
evhtp_ssl_cfg scfg = {
.pemfile = ssl_pem,
.privfile = ssl_pem,
.cafile = ssl_ca,
.ciphers = "RC4+RSA:HIGH:+MEDIUM:+LOW",
.ssl_opts = <SSL SPECIFIC FLAGS>,
.enable_scache = 1,
.scache_timeout = 1024,
.scache_init = evhtp_ssl_scache_builtin_init,
.scache_add = evhtp_ssl_scache_builtin_add,
.scache_get = evhtp_ssl_scache_builtin_get,
.scache_del = NULL,
};
* please note that .scache_init, .scache_add, .scache_get, and .scace_del
are function points to allow for a user to define their own session cache
mechanism. Libevhtp has a few default built-in cache functions:
evhtp_ssl_scache_builtin_init,
evhtp_ssl_scache_builtin_add,
evhtp_ssl_scache_builtin_get,
evhtp_ssl_scache_builtin_del
Another side note here is that currently the builtin functions do not expire,
this will be fixed in the next beta-release.
* The second step is to enable the use of the SSL backend by calling:
evhtp_use_ssl(evhtp_t *, evhtp_ssl_cfg *);
- Regular expression based path callback functions added:
evhtp_set_regex_cb(evhtp_t *, "^(/path_w_regex/).*", callback, args);
Using the case above, any path/uri in the request with /path_w_regex/*, the API
will execute your defined callback function. The output of which is the same as
any other defined callback.
- Added _htp_callbacks_find_callback_woffsets(), which (if regex) will set 2 integer
variables in the evhtp_rquest_t structure defining the beginning and end of a matched
URI/path.
- _htp_callback_new() has been modified to create regex based evhtp_callback_t's
- Made the evhtp_request_t structure private, various get/set functions have been added
to deal with the internals.
- Modified compile to support libonigurmura, a BSD licensed cross-platform regular expression
library. Currently this is only used to support posix regex functionality.
