The event monitor is used to get keyboard events when there is no window, but
since it is a global monitor to the current process, we don't want it in a
library setting.

This was once central, but now it's almost unused. Only vf_divtc still
uses it for extremely weird and incomprehensible reasons. The use in
stream.c is trivial. Replace these, and remove mpbswap.h.

Until now, the audio chain could handle both little endian and big
endian formats. This actually doesn't make much sense, since the audio
API and the HW will most likely prefer native formats. Or at the very
least, it should be trivial for audio drivers to do the byte swapping
themselves.
From now on, the audio chain contains native-endian formats only. All
AOs and some filters are adjusted. af_convertsignendian.c is now wrongly
named, but the filter name is adjusted. In some cases, the audio
infrastructure was reused on the demuxer side, but that is relatively
easy to rectify.
This is a quite intrusive and radical change. It's possible that it will
break some things (especially if they're obscure or not Linux), so watch
out for regressions. It's probably still better to do it the bulldozer
way, since slow transition and researching foreign platforms would take
a lot of time and effort.

When compiling semaphore_osx.c on win32, the following error happened:
/usr/i686-w64-mingw32/include/semaphore.h:160:6: error: unknown type name 'mode_t'
This is because this system header references symbols that are not
not defined anywhere. This is clearly a bug in pthreads-w32, but has
been known and unfixed since 2012, so add a hack to fix it.
We build semaphore_osx.c this way because it saves us an extra configure
check. On win32, Linux, etc. it's empty and contains
"#include <semaphore.h>" only.
Should fix #1108.

osdep/semaphore.h is the file that defines the very #define that is
tested in the #ifdef that wraps its inclusion, so it was never compiled.

OSX is POSIX conformant, but it's a sad joke: it provides the
<semaphore.h> prototype as the standard demands, but they're empty
wrappers, and all functions just return ENOSYS.
Emulate them similar to how osdep/io.h emulate filesystem functions on
Windows. By including the header, working sem_* functions become
available.
To make it async-signal safe, use a pipe for wakeup (write() is AS-safe,
but mutexes can't be). Actually I'm not sure anymore if we really need
AS-safety, but for now the emulation can do it.
On Linux, the system provides a far more efficient and robust
implementation. We definitely want to avoid using the emulation if
possible, so this code is active on OSX only. For convenience we always
build the source file though, even if the implementation is disabled and
no actual code is generated.
(Linux provides working semaphores, but is formally not POSIX
conformant. On OSX it's the opposite. Is POSIX a complete joke?)

I'm not quite sure what we should actually do (maybe read input
commands?), but interpreting input as terminal key sequences is
definitely weird. So just do nothing.
|

Do terminal input with a thread, instead of using the central select()
loop. This also changes some details how SIGTERM is handled.
Part of my crusade against mp_input_add_fd().

The Windows version of tmpfile is actually pretty broken. It tries to
create the file in the root directory of the current drive, which means
on Vista and up, it normally fails due to insufficient permissions.
Replace it with a version that uses GetTempPath.
Also remove the Windows-specific note about automatic deletion of the
cache file. FILE_FLAG_DELETE_ON_CLOSE is available in NT, and it should
be pretty reliable.

bstr.c doesn't really deserve its own directory, and compat had just
a few files, most of which may as well be in osdep. There isn't really
any justification for these extra directories, so get rid of them.
The compat/libav.h was empty - just delete it. We changed our approach
to API compatibility, and will likely not need it anymore.
|

|
|
|

Just so I can move this file without modifying its contents in the next
commit.
compat/compiler.h is to be moved to osdep/ with the next commit, so add
a dummy header.

Rather than "magic" numbers, use meaningful constant names provided by
unistd.h.

The correct type is HANDLE, not HANDLE*, though this change shouldn't
affect functionality.

This is independent of terminfo/termcap, and supports more keys.
Originally, the goal was just extending the set of supported key
sequences, but since the terminfo stuff actually makes this much harder,
and since it's a big blob of bloated legacy crap, just drop it. Instead,
use hardcoded tables.
It's pretty easy to get on the same level as the old code (with fewer
LOC), and we avoid additional error situations, such as mallocs which
could fail (the old code just ignores malloc failures). We also try to
support some xterm escape sequences, which are in relatively widespread
use. (I'm not sure about the urxvt ones.)
Trying to deal with xterm shift/ctrl/alt modifiers is probably a bit
overcomplicated, and only deals with prefixes - xterm randomly uses
prefix sequences for some keys, and suffixes for others (what the heck).
Additionally, try to drop unknown escape codes. This basically relies
on a trick: in almost 100% of all situations, a read() call will
actually return complete sequences (possibly because of pipe semantics
and atomic writes from the terminal emulator?), so it's easy to drop
unknown sequences. This prevents that they trigger random key bindings
as the code interprets the part after ESC as normal keys.
This also drops the use of terminfo for sending smkx/rmkx. It seems
even vt100 (to which virtually everything non-legacy is reasonably
compatible with) supports the codes we hardcode, so it should be fine.
This commit actually changes only the code if terminfo/termcap are not
found. The next commit will make this code default.

Surprisingly, WaitFor* works on console handles. We can simply run the
code for reading the console in a thread, and don't have to worry about
crazy win32 crap in the rest of the player's input code anymore.
This also fixes the issue that you couldn't unpause the player from the
terminal, because the player would stop polling for input.

In particular, remove all the stupid debug printfs from the win code.

Something about a non-working MinGW thing? Really, I don't care. It
also prevents using the console API properly.

We already redirect all terminal output through our own wrappers (for
the sake of UTF-8), so we might as well use it to handle ANSI escape
codes.
This also changes behavior on UNIX: we don't retrieve some escape codes
per terminfo anymore, and just hardcode them. Every terminal should
understand them.
The advantage is that we can pretend to have a real terminal in the
normal player code, and Windows atrocities are locked away in glue
code.

Almost nothing was left of it.
The only thing this commit actually removes is support for reading
input commands from stdin. But you can emulate this via:
--input-file=/dev/stdin --input-terminal=no
However, this won't work on Windows. Just use a named pipe.

Prior to this commit we had a list of key modifiers and checked against that.
Actually, the Cocoa framework has a built in way to do it and it involves
calling performKeyEquivalent: on the menu instance.
Fixes #946

that depended on this assumption.

There is no standard mechanism for detecting endianess. Doing it at
compile time in a portable way is probably hard. Doing it properly
with a configure check is probably hard too. Using the endian
definitions in <sys/types.h> (usually includes <endian.h>, which is
not available everywhere) works under circumstances, but the previous
commit broke it on OSX.
Ideally all code should be endian dependent, but that is not possible
due to the dependencies (such as FFmpeg, some video output APIs, some
audio output APIs).
Create a header osdep/endian.h, which contains various fallbacks.
Note that the last fallback uses libavutil; however, it's not clear
whether AV_HAVE_BIGENDIAN is a public symbol, or whether including
<libavutil/bswap.h> really makes it visible. And in fact we don't want
to pollute the namespace with libavutil definitions either. Thus it's
only the last fallback.

Seems like a good idea, even if it's basically unused (yet).
Also document requirements on the functions (they're not obvious).

Until now, the config functions added various allocations to the user-
provided talloc context. Make it so that they're all under the returned
allocation instead. This allows avoiding having to create an extra
temporary context for some callers, and also avoids adding random memory
leaks by accidentally passing a NULL context.
mp_find_all_config_files() has to be changed not to return a pointer
into the middle array for this to work. Make it add paths in order
(instead of reverse), and then reverse the array entries after that.
Also remove the declarations for the win-specific private functions.
Remove STRNULL(); it's barely needed anymore and the functions are
not called with NULL filenames anymore.

Search $XDG_CONFIG_HOME and $XDG_CONFIG_DIRS for config files.
This also negates the need to have separate user and global variants of
mp_find_config_file()

Does anyone actually use this?
For now, update it, because it's the only case left where an option
points to a global variable (and not a struct offset).

Error handling is slightly reduced: we assume that setting a pipe
to non-blocking can never fail.

This is mostly covered by the OSX workaround, if the timeout is very
high. It also means that with systems using 32 bit time_t, the time will
overflow 2036 already, instead of 2037, but we don't consider this a
problem.

Some operating systems apparently can't deal with really long timeouts
in pthread_cond_timedwait(). Passing a time about 300000 in the future
makes the call return immediately. (tv_sec/time_t doesn't overflow in
this situation.) Reduce the wait time to about 100 days, which seems
to work fine.
The list of affected OSes follows: OSX

Sigh... of course the type of the (?:) exprsssion is double, so
INT64_MAX was converted to double, which is a problem.
|
| |
|
|
|
|
|
| |
Probably more correct and better readable. Although the special-casing
of 0x1p63 is weird in terms of readability (the value itself is
INT64_MAX+1, so it's already outside of range, but INT64_MAX is not
exactly representable with double precision).
|
| |
|
|
|
|
|
| |
This usually can't happen, because even if time_us (first input value)
is INT64_MAX, the value added to tv_sec will be about 2^43, and tv_sec
will be <2^31, far below a possible overflow in 64 bits. But should
time_t be 32 bits (32 bit Linux/Windows?), an overflow could happen.

It can easily happen that mp_time_us_to_timespec() gets a time in the
past, and then the time difference will be negative. Regression
introduced in commit f47a4fc3.
Also fix an underflow check in mp_add_timeout().
|
| |
|
|
|
|
| |
Use the time as returned by mp_time_us() for mpthread_cond_timedwait(),
instead of calculating the struct timespec value based on a timeout.
This (probably) makes it easier to wait for a specific deadline.

One problem is that for example stdio functions won't restart syscalls
manually, and instead treat EINTR as an error. So passing SA_RESTART is
the only sane thing to do, unless you have special requirements, which
we don't.
|
| |
|
|
| |
Closer to the corresponding standard function pthread_cond_timedwait.

This was part of osdep/threads.c out of laziness. But it doesn't contain
anything OS dependent. Note that the rest of threads.c actually isn't
all that OS dependent either (just some minor ifdeffery to work around
the lack of clock_gettime() on OSX).

glob-win.c wasn't big, so it was easier to rewrite it. The new version
supports Unicode, handles directories properly, sorts the output and
puts all its allocations in the same talloc context to simplify the
implementation of globfree.
Notably, the old glob had error checking code, but didn't do anything
with the errors since the error reporting code was commented out. The
new glob doesn't copy this behaviour. It just treats errors as if there
were no more matching files, which shouldn't matter for mpv, since it
ignores glob errors too.
To match the other Windows I/O helper functions, the definition is moved
to osdep/io.h.

I hate tabs.
This replaces all tabs in all source files with spaces. The only
exception is old-makefile. The replacement was made by running the
GNU coreutils "expand" command on every file. Since the replacement was
automatic, it's possible that some formatting was destroyed (but perhaps
only if it was assuming that the end of a tab does not correspond to
aligning the end to multiples of 8 spaces).

Should make integreating with some event loops easier. Untested.
