net.server_epoll: Prevent stack overflow of opportunistic writes
net.http.files serving a big enough file on a fast enough connection
with opportunistic_writes enabled could trigger a stack overflow through
repeatedly serving more data that immediately gets sent, draining the
buffer and triggering more data to be sent. This also blocked the server
on a single task until completion or an error.
This change prevents nested opportunistic writes, which should prevent
the stack overflow, at the cost of reduced download speed, but this is
unlikely to be noticeable outside of Gbit networks. Speed at the cost of
blocking other processing is not worth it, especially with the risk of
stack overflow.

(This file was created from https://prosody.im/doc/installing_from_source on 2013-03-31) ====== Installing from source ====== ==== Dependencies ==== There are a couple of libraries which Prosody needs installed before you can build it. These are: * lua5.1: The Lua 5.1 interpreter * liblua5.1: Lua 5.1 library * libssl 0.9.8: OpenSSL * libidn11: GNU libidn library, version 1.1 These can be installed on Debian/Ubuntu with the packages: lua5.1 liblua5.1-dev libidn11-dev libssl-dev On Mandriva try: urpmi lua liblua-devel libidn-devel libopenssl-devel On other systems... good luck, but please let me know of the best way of getting the dependencies for your system and I can add it here. ==== configure ==== The first step of building is to run the configure script. This creates a file called 'config.unix' which is used by the next step to control aspects of the build process. All options to configure can be seen by running ./configure --help. Sometimes you won't need to pass any parameters to configure, but on most systems you shall. To make this a little easier, there are a few presets which configure accepts. You can load a preset using: ./configure --ostype=PRESET Where PRESET can currently be one of: 'debian', 'macosx' or (in 0.8 and later) 'freebsd' ==== make ==== Once you have run configure successfully, then you can simply run: make Simple? :-) If you do happen to have problems at this stage, it is most likely due to the build process not finding the dependencies. Ensure you have them installed, and in the standard library paths for your system. For more help, just ask ;-) ==== install ==== At this stage you should be able to run Prosody simply with: ./prosody There is no problem with this, it is actually the easiest way to do development, as it doesn't spread parts around your system, and you can keep multiple versions around in their own directories without conflict. Should you wish to install it system-wide however, simply run: sudo make install ...it will install into /usr/local/ by default. To change this you can pass to the initial ./configure using the 'prefix' option, or edit config.unix directly. If the new path doesn't require root permission to write to, you also won't need (or want) to use 'sudo' in front of the 'make install'. Have fun, and see you on Jabber!
