Hector Martin 0426cb523a Fix: Rework SSL poll event handling to avoid infinite loops
The downstream connection callback must only be invoked when the event
that SSL requests for the connection to make progress has actually
occured. Otherwise, the downstream callback might do nothing but
re-queue an unrelated event (e.g. in user_net_io_want_write), and the
event loop comes around instantly while making no progress. Track the
SSL-requested events separately and deliver the required downstream
event when they fire.

Sample strace:

epoll_wait(0, {{EPOLLIN, {u32=96, u64=96}}}, 91, 10000) = 1
: net_ssl_callback in state tls_st_need_write calls cb NET_EVENT_WRITE
: User writes data, OpenSSL tries to write data
write(96, <snip>..., 170) = -1 EAGAIN (Resource temporarily unavailable)
: handle_openssl_error requests NET_EVENT_WRITE
epoll_ctl(0, EPOLL_CTL_MOD, 96, {EPOLLOUT, {u32=96, u64=96}}) = 0
: User callback then requests NET_EVENT_READ|NET_EVENT_WRITE
epoll_ctl(0, EPOLL_CTL_MOD, 96, {EPOLLIN|EPOLLOUT, {u32=96, u64=96}}) =
: Data available for *reading*
epoll_wait(0, {{EPOLLIN, {u32=96, u64=96}}}, 91, 10000) = 1
: net_ssl_callback in state tls_st_need_write calls cb NET_EVENT_WRITE
: again...

This is important for Debian, Ubuntu and other systems based on them. Details:

Have in mind that there are MIPS, ARM and many other architectures...

Jan Vidar Krey 7f2ffd7e1c Fix CMake/SQLite path issues on 64-bit Ubuntu 14.04 2014-05-08 13:33:45 +02:00
Jan Vidar Krey e2b0757f4a Improved flood control counting to strictly not allow more than
the given amount of messages in the configured interval.

The previous behavior allowed n+2 messages in the interval, due to
two off by one comparison rules.

In addition, if flooding is detected then each new message after the flooding
is detected will reset the interval timer, which means the client
cannot send another message until the timeout interval expires.

Jan Vidar Krey 550740f715 Fix bug #198 - Timers could cause infinite loops
This could essentially happen due to time drift,
high load, or the process being put in sleep for a while.

The reason is that recurring timers could be added to the same time slot
as the timeslot being handled.

Jan Vidar Krey d73d213bc4 Remove the chat_is_privileged_plugin because it fails to compile 2013-03-23 22:47:32 +01:00
mimicmod 5672ba14e3 Added mod_chat_history_sqlite and mod_chat_is_privileged.
Use file=/path/to/db to specify the database file where chat history should be stored. Other config variables are the same as those for mod_chat_history.

Jan Vidar Krey cd5c4ee622 Optimize lookups by CID and nick.
This used to be a linear search O(n), but is now done
as a red-black tree O(log n) instead.

These operations can be further opimized with a hash-table
which would acheive near constant time lookups.

Jan Vidar Krey 2d6f69d299 Cleaned up usage of linked lists and added missing functionality.
- Added a list_remove_first() which is generally better than list_remove()
  provided you want to remove the first element.
- Added a list_append_list() to append and move all nodes from one list to
  another.

Jan Vidar Krey b81bb2cbd9 Cleaned up all list iterations, added macro named LIST_FOREACH.
Previously you would have to do something like this:

for (type foo = (type) list_get_first(list); foo; foo = (type) list_get_next(list)
{
    /* code */
}

Now, you can instead write this as:

LIST_FOREACH(type, foo, list,
{
    /* code */
})

Basically, boilerplate stuff including the casting is gone.

Jan Vidar Krey 1fbde2b0fd Re-factored the ADC client code to use the new connection establishment API. 2013-02-05 22:43:59 +01:00
Jan Vidar Krey 92b65a0e14 Created a connection establishment API.
This API provides transparent asynchronous DNS lookups
with both IPv4 and IPv6 support, and in addition will try
to connect to all addresses until one of them work.

This implements the "happy eyeballs" algorithm provided that the client supports IPv6
and that the DNS records provides both IPv6 and IPv4 addresses.

Jan Vidar Krey 4d438e1e90 Don't poll the connection monitor if there are no connections added.
This caused the backends to return an error code, which
in turn ended the mainloop. However, several other things
also might occur in the main loop, such as DNS lookups which
come prior to creating any connections that in turn would be monitored.
