editorconfig: We use tabs This lets various supporting editors know what indentation style should be used for files in the repo. See https://editorconfig.org/ Coding style for Lua files is described in `doc/coding_style.md` The 3-space indentation in `configure` comes from its LuaRocks inheritance. `doc/doap.xml` is normalized with `xmllint` which spits out 2-space indentation.

mod_s2s: Handle measurement where the local host is unknown This could happen with Dialback-only connections or others that were missing the stream 'to' attribute.

mod_s2s: Guard against missing 'to' on incoming stream Given an incoming <stream:stream from="example.com"> this line would have mistakenly reported the 'from' as the local host. Neither are technically required and may be missing, especially on connections used only for Dialback. Outgoing connections initiated by Prosody always have 'from_host' and 'to_host', so it is safer to check it this way.

net.server_epoll: Fix traceback-causing typo Caused "attempt to index a string value (local 'data')", but only if keep_buffers is set to false, which is not the default. Introduced in 917eca7be82b

net.server_epoll: Ensure timeouts match epoll flags Read and write timeouts should usually match whether we want to read or write.

net.server_epoll: Skip reset of read timeout when not reading Should avoid rare but needless timer interactions

net.server_epoll: Reduce timer churn during TLS handshake Instead of removing and readding the timer, keep it and adjust it instead. Should reduce garbage production a bit.

net.server_epoll: Use only fatal "write" timeout during TLS negotiation Only real difference between the read and write timeouts is that the former has a callback that allows the higher levels to keep the connection alive, while hitting the later is immediately fatal. We want the later behavior for TLS negotiation.

net.server_epoll: Optimize concatenation of exactly 2 buffer chunks Saves a function call. I forget if I measured this kind of thing but IIRC infix concatenation is faster than a function call up to some number of items, but let's stop at 2 here.

net.server_epoll: Avoid allocating a buffer table for single writes writebuffer is now string | { string } Saves the allocation of a buffer table until the second write, which could be rare, especially with opportunistic writes.
