* net.server_epoll: Avoid concatenating buffer with single itemKim Alvefur2019-12-281-1/+1
| | | | | | | | | | | | | | Saves creating a string that'll be identical to buffer[1] anyways, as well as a C function call. Depending on Lua version and length of the string, this could be reusing an interned string, but a longer one would probably be duplicated for no reason. Having exactly one item in the buffer seems like it would be fairly common, but I have not done an extensive study. If opportunistic writes are enabled then it will be even more likely. This special case could be optimized like this in table.concat but it does not look like it is.

* util.error: Move default for numeric error code to net.http.serverKim Alvefur2019-12-141-1/+1
| | | | | | Stanza errors can also have numbers but these are a legacy thing and rarely used, except in MUC. HTTP errors on the other hand always have a number.
* net.server_epoll: Use monotonic time for schedulingKim Alvefur2019-12-081-9/+11
| | | | Timer API of passing wallclock time remains
* net.server_epoll: Change timer rescheduling method to match util.timerKim Alvefur2019-12-081-2/+3
| | | | | Relative to current time instead of absolute time, in preparation for switching to monotonic time.
* net.server_epoll: Remove unused function for adding timer at absolute timeKim Alvefur2019-12-081-8/+3
| | | | This won't make sense if we switch to monotonic time
* net.server_epoll: Add debug logging for delayed readingKim Alvefur2019-12-071-0/+1
| | | | | | | | | | | | | | | | In :onreadable, if there is still buffered incoming data after reading from the socket (as indicated by the :dirty method, usually because LuaSocket has an 8k buffer that's full but it read a smaller amount), another attempt to read is scheduled via this :pausefor method. This is also called from some other places where it would be pointless to read because there shouldn't be any data. In the delayed read case, this should report that the socket is "dirty". If it reports that the socket is "clean" then the question is where the buffer contents went? If this doesn't get logged after the scheduled time (0.000001s by default) then this would suggests a problem with timer or scheduling.
* net.connect: Mention RFC 6724 regressionKim Alvefur2019-12-072-0/+2
| | | | | Default Address Selection algorithm is not applied, resulting in a strong bias towards IPv4.
* net.connect: Add some TODOs and FIXMEsKim Alvefur2019-12-073-1/+10
| | | | And mention issue numbers: #1246, #1428 and #1429
* net.server_select: Remove prefix added to TLS handshaker errorsKim Alvefur2019-12-011-1/+1
| | | | For consistency. None of the other implementations do this.
* net.http: Set ALPN on requestsKim Alvefur2019-11-291-1/+1
| | | | | | Shouldn't hurt. Revert if it turns out it does. Supported in LuaSec 0.8. Should be ignored otherwise.
* net.websocket: Fix traceback in case of ondisconnect being called twiceMatthew Wild2019-11-261-0/+1
| | | | | We want to figure out what situations the double ondisconnect happens in, and aim to fix the root cause in the future.

| | | | | | | | | | This is to prepare for fixing #1459. An IPv6 literal in [ ] brackets does not pass IDNA and resolving it fails there.

* | net.server_epoll: Handle getpeer/sockname returning a normal errorKim Alvefur2019-10-121-2/+2
| | | | | | | | | | These will sometimes return nil, "Transport not connected" but not throw a hard error. This shouldn't be treated as success.
* | net.server_epoll: Fix to get remote IP on direct TLS connectionsKim Alvefur2019-10-121-0/+1
| | | | | | | | | | | | | | | | A Direct TLS connection (eg HTTPS) gets turned into a LuaSec handle before the :updatenames call done in the :connect method. LuaSec does not expose the :getpeername and :getsockname methods, so the addresses remain obscured, making debugging trickier since the actual IP addrerss connected to does not show up.
* | net.server_epoll: Move a log message to improve orderingKim Alvefur2019-10-121-1/+1

| | | | | | | | | | The similar logging in mod_c2s and mod_s2s does not cover all connections, like HTTPS or other Direct TLS ports.
