2017-07-11Improve and centralize socket engine event counters.Robin Burchell
The write counters were close to useless because they were only incremented on a write "event" which is only triggered when writing would block. Read handling was a little more useful in that all reads must happen through the socket engine, so these were happening at the correct time, but we can clean this up by doing it in the SE itself rather than each platform port. This means that both read and write events are now easily and usefully defined as "a syscall of either read or write was attempted". We also count empty read and write events as being an event, because they still were an attempt to poll a socket in some way. This may help to identify "bad" code which is repeatedly trying to read a socket for some reason. Lastly, we check for failed read/write calls, and log them as an error event. A lot of the time, this is how sockets are determined as being disconnected (ie. at read/write time). While we're at it, split Update() in two to make the calls more self-describing. This has no real impact since only one call is made at a time anyway.

2012-10-12Windows: In-depth cleanup (see details)ChrisTX
-Fix x64 builds for Windows. Now all configurations compile. -Remove the non-working rebase stuff. -Remove the Windows fork hack and instead use FreeConsole() to emulate the behavior. This directly allows us to compile with ASLR, which is turned on now. -Remove the old IPC mechanism for the removed GUI. This is not needed anymore as the GUI wasn't ever supported on anything newer than 1.2 -Remove the WIN32/WINDOWS macros. _WIN32 is supported on all x86-based VC++ targets, so that's what we need. -Enable optimizations for release builds. -De-duplicate printf_c(), it was previously copy-pasted into colors.h for configure -Add the VC++ specific bad files in .gitignore -Disable PID writing on Windows. This is only making sense for *nix builds. -Replace the CPU usage retrieval with an algorithm analogous to the *nix behavior. Also supports separated now/total values. (Tested with a dummy busy loop - seems working) -Removed certain unused functions and variables -Remove stdint defines from the windows wrapper -Remove CRT debug alloc. This is a bad idea as it would define a macro to replace free which breaks builds. -Re-evaluated the warnings list, commented it. -Moved inspircd_config/_version to include/ to match *nix -Removed the creation of inspircd_se_config, as it isn't used at all. -Made non-git builds show as "r0" instead of "r" (thanks to @SaberUK for pointing this out) -Fixed up m_spanningtree's project paths. Now all configurations (debug/release x86/x64) have been tested and build properly. -Moved FindDNS out of the wrapper and matched its log behavior with *nix. (It's pointless having it in the wrapper after the recent slimming down) -Replaced random/srandom wrappers with a mechanism that tries to use Windows' Random API first is no SSL module is loaded. -Removed more old junk from support for compilers older than VC++ 2010 (we don't have project files for these, so compiling them would be hard anyways) -Removed the unused ClearConsole() -Removed unused includes from the wrapper. Also, do not include psapi.h here if we don't link psapi.lib. This should be done where appropriate. -Made inet_aton an inline function for increased performance -C4800, performance warning about bool forcing, resolved at all occurrences. -C4701, uninitialized variable 'cached', resolved at all occurrences. -dlerror() was migrated out of the wrapper for more thread safety (no global buffer being shared) and increased performance. -Removed the wrong CRT debug flags. This drains a lot of performance. -Removed the clock_gettime/gettimeofday wrappers -Replaced all TCHAR/ANSI mix-ups of functions with the correct respective function. -Added a block of C4355 for < VS2012 -Update project files for c870714

2009-10-24Remove IOCP socket enginedanieldg
IOCP has been experimental since its introduction, and has not worked correctly for some time. Since we have no windows developer, remove the dead code. Most of the advantages of IOCP are not used by an ircd process regardless: we do not use threads for our client processing, and we add an extra copy operation that eliminates any gain from OS-level buffer reuse. git-svn-id: http://svn.inspircd.org/repository/trunk/inspircd@11970 e03df62e-2008-0410-955e-edbf42e46eb7

2008-04-15the select socket engine went on the assumption that a socket may remove ↵brain
itself from the socket engine in the middle of the loop. Cull lists did away with this late 1.0, early 1.1, so there is now no need to keep this archaic system in here and we can halve the number of loops per cycle down to half what they used to be. git-svn-id: http://svn.inspircd.org/repository/trunk/inspircd@9512 e03df62e-2008-0410-955e-edbf42e46eb7
