function. Because synergy doesn't use posix cancellation, it
cannot wake up a thread waiting on a condition variable. So
the wrapper would wake up periodically to test if the thread was
cancelled (according to synergy's cancellation state) then go
back to waiting. Well the condition could be signalled while
we're testing and be lost and we'd never return from the wait.
So now we wake up after a maximum timeout and return to the
caller. The caller must check for this spurious wakeup but all
callers should do this anyway so we're okay there.
and Xinerama correctly. Also was using '#if defined(...)' instead
of '#if ...' for testing configure macros in some places. This
yields the wrong answer if the macro is set to 0, which means
missing/disabled.
return 0 when O_NDELAY is set and there is nothing to read. We
want the O_NONBLOCK behavior where read returns -1 and sets
errno to EAGAIN when there is nothing to read.
didn't support them and the emulated versions were just as good
except for a performance problem with excessive locking and
unlocking of a mutex. So this also changes IArchString to
provide string rather than character conversion so we can lock
the mutex once per string rather than once per character.
multiple systems with automake, with X Windows and Carbon window
system APIs supported. It's also a starting port for supporting
win32 builds using mingw. OS X support is incomplete; the tree
will compile and link but the binaries will not function.
broken when support for binary data was added. The terminating
NUL was included in the string as a character (that's in addition
to the terminating NUL added by std::string).
poll() but there was a race condition where the thread trying
to unblock poll() could send the signal before the polling
thread had entered poll(). Now using a pipe and polling on
that and the client's sockets, and just writing a byte into
the pipe to unblock poll. This persists until the next call
to poll() so we might force poll() to return once unnecessarily
but that's not a problem. This change makes the BSD code
similar to the winsock code, which uses a winsock event instead
of a pipe.
event loop model. Streams, stream filters, and sockets are
converted. Client proxies are almost converted. CServer is
in progress. Removed all HTTP code. Haven't converted the
necessary win32 arch stuff.
an event queue and events, TCP sockets converted to use events,
unix multithreading and network stuff converted, and an X Windows
event queue subclass.
