global: stop including fd-set-nonblock.h & fd-close-on-exec.h directly

global: start relying on io_remove{,_closed}(NULL) being a no-op Cleanup performed with the following semantic patch: @@ expression E; @@ - if (E != NULL) { - io_remove(&E); - } + io_remove(&E); @@ expression E; @@ - if (E != NULL) { - io_remove_closed(&E); - } + io_remove_closed(&E);

lib: io_loop_extract_notify_fd() - Don't crash if no notifys have been added

lib: ioloop-notify-kqueue wasn't storing source filename.

io: Add source filename This will make debugging alot easier when you can see what the filename is as well.

lib: Fixed io_loop_extract_notify_fd() to compile with kqueue.

lib: Added io_loop_extract_notify_fd()

lib: Log notify IO leaks when ioloop is destroyed.

lib: io_add_notify() wasn't setting struct io.source_linenum

lib: kqueue notification should trigger also on file renames. For example if dovecot.index.log is renamed to dovecot.index.log.2, we should notice that since there's now a new dovecot.index.log containing new changes.

Changed i_close_fd() API to set the fd to -1 after closing.

Replaced (void)close(fd) and close_keep_errno() with i_close_fd(). i_close_fd() preserves the errno and logs an error if the close() fails.

Renamed lib/*-internal.h files to lib/*-private.h for consistency.

Replaced "ioloop log" with a more generic "ioloop context". The context can call multiple callbacks that can do anything they want, including setting the log prefix.

Removed ioloop_timezone. It's not working nowadays. --HG-- branch : HEAD

kqueue notify: Don't assert-cras if kevent() returns multiple events for the same io. --HG-- branch : HEAD

Don't break if io_remove() or timeout_remove() are called for non-active ioloops. --HG-- branch : HEAD

kqueue: If opening a file fails with ESTALE, don't log an error. It probably just means the file was deleted by another NFS client. --HG-- branch : HEAD

Renamed IO_NOTIFY_DISABLED to IO_NOTIFY_NOSUPPORT. IO_NOTIFY_NOSUPPORT is now also given by dnotify when trying to listen for files. Fixes busy looping with dnotify when waiting for dotlock to get deleted. --HG-- branch : HEAD

Don't crash when removing kqueue notify. --HG-- branch : HEAD

Use N_ELEMENTS() macro instead of doing sizeof()/sizeof([0]) ourself. --HG-- branch : HEAD

Changed io_add_notify() API so that it can return "file doesn't exist" error. --HG-- branch : HEAD

Don't prevent io_add_notify() from listening for files, since kqueue supports it. --HG-- branch : HEAD

These files are MIT licensed nowadays. --HG-- branch : HEAD

Various cleanups to ioloop code. --HG-- branch : HEAD

Replaced void *context from a lot of callbacks with the actual context type. Also added/fixed some context type checks. --HG-- branch : HEAD

Removed compiler warnings with NetBSD. --HG-- branch : HEAD

Fix 100% CPU usage looping when a vnode change event came but it was never untriggered. Patch by Rui Lopes (rgl ruilopes com) --HG-- branch : HEAD

Compiling fixes --HG-- branch : HEAD

Rewrote much of the kqueue code. It didn't work correctly if there were both input and output I/O handlers added for the same file descriptor. The code works now very much like epoll code. Did also several cleanups. --HG-- branch : HEAD

Cleanups: Make io_remove() do the linked list updating also for notify handlers. Removed notify_context from struct io, and moved it to a new struct inotify_io. --HG-- branch : HEAD

kqueue updates. Patch by Vaclav Haisman --HG-- branch : HEAD

Added kqueue notification support. Patch by Vaclav Haisman --HG-- branch : HEAD
