This change essentially removes mp_thread_self() and instead add
mp_thread_id to track threads and have ability to query current thread
id during runtime.
This will be useful for upcoming win32 implementation, where accessing
thread handle is different than on pthreads. Greatly reduces complexity.
Otherweis locked map of tid <-> handle is required which is completely
unnecessary for all mpv use-cases.
Note that this is the mp_thread_id, not to confuse with system tid. For
example on threads-posix implementation it is simply pthread_t.
CLOCK_MONOTONIC_RAW is linux-specific (macOS later supported it but it
has its own timer code) and not neccessarily available everywhere like
on BSDs. It makes sense to prefer it because mpv does a lot of
measurements at small intervals (e.g. every frame) so theoretically it
should be more accurate. However if the OS doesn't have it, fallback to
CLOCK_MONOTONIC instead which is almost exactly the same and very widely
supported across unix-like systems. This clock is technically optional
according to POSIX, but any half-decent OS supports it anyway (sorry
Solaris users). As a benefit, we now know that the clock from mp_time is
always monotonic.
I'd like some names to be more descriptive, but to work with 15 chars
limit we have to make some sacrifice.
Also because of the limit, remove the `mpv/` prefix and prioritize
actuall thread name.
This fixes warnings generated for `-Wunused-result` when mpv is built
with `-O1 -D_FORTIFY_SOURCE=1` or higher on clang since read/write
functions are declared with the `warn_unused_result` attribute.
Cast to void to avoid these warnings.
macOS didn't support clock_gettime until 10.12 which was released
roughly 7 years ago. Since we're breaking support for ancient OSes
anyway, we might as well break some old macOS versions for fun. This
makes 10.12 the minimum supported macOS version.
since i was going to fix the include order of stdatomic, might as well
sort the surrouding includes in accordance with the project's coding
style.
some headers can sometime require specific include order. standard
library headers usually don't. but mpv might "hack into" the standard
headers (e.g pthreads) so that complicates things a bit more.
hopefully nothing breaks. if it does, the style guide is to blame.
replace it with <stdatomic.h> and replace the mp_atomic_* typedefs with
explicit _Atomic qualified types.
also add missing config.h includes on some files.
Also apply some fixes to pthread_cond_timedwait while we're at it.
Note that by using GetSystemTimePreciseAsFileTime here we lose support
for Windows 7. This is considered acceptable.
This reverts commit 318b5471a1.
While it may work, changing these two functions in violation of their documented
behaviour for the sake of a shortcut is a hack that will spell disaster sooner or later.
This is a partial revert since the commit in question also contained a hidden
bugfix where it swapped the calculation order for time_rel.
With the previous series of commits, all internal usage has been
replaced by the nanosecond functions. There's not really any point in
keeping these around anymore plus there are macros for unit conversions
now so we can just axe them. It's worth noting that mpv_get_time_us()
obviously still needs to work for API reasons, but we can just divide
mp_time_ns() by 1000 to get the same thing.
There's a lot of wild 1e6, 1000, etc. lying around in the code. A macro
is much easier to read and understand at a glance. Add some helpers for
this. We don't need to convert everything now but there's some simple
things that can be done so they are included in this commit.
add support for vulkan through metal and a translation layer like
MoltenVK. also add the possibility to use different render timing modes
for testing.
i still consider this experimental atm.
there are currently some silly data-races in the stop/cont sighandler
due to the fact that the signal handler might get invoked in a different
thread.
this changes those sighandlers to a pipe-based approach similar to the
existing "quit" sighandler.
tio_orig and tio_orig_set are being touched inside of signal handler
which might be invoked from another thread - which makes this a data
race.
there's no real reason to set tio_orig inside of do_activate_getch2()
which is registered as a signal handler. just set it once, in
terminal_init(), before any signal handlers come in play.
this also allows removing the tio_orig_set variable completely.
do_deactivate_getch2() touches some global variables which *might have*
been fine if the terminal thread was the one that received the signal
but AFAIK which thread will handle the signal is not well defined.
in my case, when quitting mpv with CTRL+C the main thread receives the
signal rather than the terminal thread and touches those globals without
synchronization. caught by ThreadSanitizer.
the solution is to move the do_deactivate_getch2() call outside of the
signal handler.
Allows higher resolution sleeps than Sleep which has milliseconds
resolution. In practice Windows kernel does not really go below 0.5ms,
but we don't have to limit ourselves on API side of things and do the
best we can.
Linux and macOS already use nanosecond resolution for their sleep
functions. It was just being converted from microseconds before. Since
we have mp_time_ns now, go ahead and bump the precision here. The timer
for windows uses some timeBeginPeriod thing which I'm not sure what it
does really but whatever just convert the units to ms like they were
doing before. There's really no reason to keep the mp_sleep_us helper
around. A multiplication by 1000 is trivial and underlying OS clocks
have nanosecond precision.
On linux, several platforms poll for events over a fd. This has ms
accuracy, but mpv's timer is in ns now so lots of precision is lost. We
can use an mp_poll wrapper to use ppoll instead which takes a timespec
directly with nanosecond precision. On systems without ppoll this falls
back to old poll behavior. On wayland, we don't actually use this
because ppoll completely messes up the event loop for some unknown
reason.
Originally, this was added as purely a shim for macOS. However since we
want to do high resolution polling which is not neccesarily available on
all platforms, making this a generic wrapper for poll functions is
useful so rename it.
The timestamps when making a log file is actually dependent on
MP_START_TIME. This is a 10 microsecond offset that was added to the
timer as an offset. With the nanosecond change, this unit needs to be
converted as well so the offset is the same as before. After doing that,
we need to change the various mp_time_us calls in msg to mp_time_ns and
do the right conversion. This fixes the logs timestamps (i.e. so they
aren't negative anymore).
We've got an ungodly amount of OPT_REPLACED and OPT_REMOVED sitting
around in the code. This is harmless, but the vast majority of these are
ancient. 26f4f18c06 is the last commit
that touched the majority of these and of course that only changed how
options were declared so all of this stuff was deprecated even before
that. No use in keeping these, so just delete them all. As an aside,
there was actually a cocoa_opts but it had only a single option which
was replaced by something else and empty otherwise. So that entire thing
was just simply removed. OPT_REPLACED/OPT_REMOVED declarations that were
added in 0.35 or later were kept as is.
mpv saves cache by default nowadays, but vo_gpu is pretty spammy and
saves a bunch of files per shader. If someone is using the non-XDG
config directory, this all gets dumped directly into ~/.mpv which isn't
so nice. Save it to a sub directory called "cache" instead (or
alternatively submit to your XDG overlords). For unfortunate reasons,
macOS uses XDG_CONFIG_HOME and has the same legacy fallback mechanism,
so this applies to it too.
x11 and wayland had a lot of multimedia keys mapped that were missing
on windows.
Now the only ones they map that windows doesn't are `MP_KEY_WWW`,
`MP_KEY_ZOOMIN` and `MP_KEY_ZOOMOUT`, which apparently don't have any
equivalent ones on windows.
So far all the keypad keys except for `0` and `,` mapped to the same
MP_KEY_* independent of numlock state, even though different key codes
are received.
Now all the alternative functions map to appropriate MP_KEY_* defines,
with missing ones added.
This only existed as essentially a workaround for meson's behavior and
to maintain compatibility with the waf build. Since waf put everything
in a generated subdirectory, we had to put make a subdirectory called
"generated" in the source for meson so stuff could go to the right
place. Well now we don't need to do that anymore. Move the meson.build
files around so they go in the appropriate place in the subdirectory of
the source tree and change the paths of the headers accordingly. A
couple of important things to note.
1. mpv.com now gets made in build/player/mpv.com (necessary because of
a meson limitation)
2. The macos icon generation path is shortened to
TOOLS/osxbundle/icon.icns.inc.
If we see "C" in one of the language vars we check, don't treat it as a language tag.
Once we've checked everything, if we don't have any languages, but saw "C" anywhere, fall back on "en".
4502522a7a implemented cache directories
but only on linux which meant other OSes continued to save this stuff in
their config directory. Since we turned on cache by default, people are
getting cache files in there which is understandably causing some
confusion. Let's go ahead and implement a separate cache directory for
windows since there seems to be some established conventions for this
already. For people using the portable_path, the cache is saved in a
subdirectory within the portable_path since the idea is for that to be
completely self contained.
the reason for checking `EBADF|EINVAL` specifically is unknown. but it's
clearly not working as intended since it can cause issues like #11795.
instead of checking for "bad errors" check for known "good errors" where
we might not want to break out. this includes:
* EINTR: which can happen if read() is interrupted by some signal.
* EAGAIN: which happens if a non-blocking fd would block. `tty_in` is
_not_ non-blocking, so EAGAIN should never occur here. but it's added
just in case that changes in the future.
Fixes: https://github.com/mpv-player/mpv/issues/11795
Closes: https://github.com/mpv-player/mpv/pull/11805
first of all, POLLERR is supposed to be ignored in `.events` and only
returned in `.revents`.
secondly select()'s exceptfds does not have a 1:1 correspondence with
POLLERR. thankfully, the only caller of this function (in terminal-unix)
never set the POLLERR flag so the errorfds were unused anyways.
so go ahead and remove it entirely instead of pretending we can emulate
something that's not possible.
This adds cache as a possible path for mpv to internally pick
(~/.cache/mpv for non-darwin unix-like systems, the usual config
directory for everyone else). For gpu shader cache and icc cache,
controlling whether or not to write such files is done with the new
--gpu-shader-cache and --icc-cache options respectively. Additionally,
--cache-on-disk no longer requires explicitly setting the --cache-dir
option. The old options, --cache-dir, --gpu-shader-cache-dir, and
--icc-cache-dir simply set an override for the directory to save cache
files. If unset, then the cache is saved in XDG_CACHE_HOME.
A pain point for some users is the fact that watch_later is stored in
the ~/.config directory when it's really not configuration data. Roughly
2 years ago, XDG_STATE_DIR was added to the XDG Base Directory
Specification[0] and its description, user-specific state data, actually
perfectly matches what watch_later data is for. Let's go ahead and use
this directory as the default for watch_later. This change only affects
non-darwin unix-like systems (i.e. Linux, BSDs, etc.). The directory
doesn't move for anyone else.
Internally, quite a few things change with regards to the path
selection. If the platform in question does not have a statedir concept,
then the path selection will simply return "home" instead (old
behavior). Fixes#9147.

macOS really has completely different path conventions that mpv doesn't
take into account and it treats it just like any other old unix-like
system. This means mpv enforces certain conventions on it (like all the
XDG stuff) that doesn't really apply. Since we'd like to use more of
this but at the same time not distrupt mac users even more, let's just
copy and paste the current code to a new file, update the build and call
it a day. This way, the paths of these two platforms can more freely
diverge.
c784820454 introduced a bool option type
as a replacement for the flag type, but didn't actually transition and
remove the flag type because it would have been too much mundane work.
Add xoshiro as a PRNG implementation instead of relying
on srand() and rand() from the C standard library. This,
in particular, lets us avoid platform-defined behavior with
respect to threading.
During execve() ignored and blocked signals carry over to the child
process, though apparently for SIGCHLD (which the bug report was about)
this is implementation-defined.
fixes#9613
Not all deprecated symbols were removed. Only three events were removed for now
since these are not used internally.
This bumps the library version to 2.0.
This seems to work on gcc, clang and mingw as-is, but I made it
conditional on __GNUC__ just in case, even though I can't figure out
which compilers we care about that don't export this define.
Also replace all instances of assert(0) in the code by MP_UNREACHABLE(),
which is a strict improvement.
Before this commit, timeBeginPeriod(1) was set once when mpv starts,
and the timers remained hi-res till mpv exits.
Now we do the same as before on Windows version < 10.
On Windows 10+ we now use timeBeginPeriod if needed, per timeout.
To force a mode regardless of Windows version, set env MPV_HRT:
- "always": the old behavior - hires timers as long as mpv runs.
- "perwait": sets 1ms timer resolution if timeout <= 50ms.
- "never": don't use timeBeginPeriod at all.
It was observed that on Windows 10 we lose about 0.5ms accuracy of
timeouts with "perwait" mode (acceptable), but otherwise it works
well for continuous timeouts (one after the other) and random ones.
On Windows 7 with "perwait": continous timeouts are accurate, but
random timeouts (after some time without timeouts) have bad
accuracy - roughly 16ms resolution instead of the requested 1ms.
Windows 8 was not tested, so to err on the side of caution, we keep
the legacy behavior "always" by default.
If an unknown ESC sequence is detected where an ASCII char <X> follows
the ESC, mpv interprets it as ALT+<X>, which is the traditional
terminal encoding of ALT+letter.
However, if <X> is '[' then it's a CSI sequence which continues after
the '[', and has its own termination rules (can be many chars).
Previously, mpv interpreted unknown CSI sequences as (incorrect) ALT+[
followed by (incorrect) "keys" from the rest of the sequence.
In this commit, if a unknown CSI sequence is detected, mpv ignores
exactly the complete sequence.
When using "stty susp ''" to disable sending the TSTP signal with ^Z,
mpv didn't recognize ^Z correctly in the terminal:
[input] No key binding found for key 'Ctrl+2'.
Because ASCII 26 (^Z) and above were incorrectly considered ^<NUMBER>.
This commit moves the cutoff between letters/numbers from 25 to 26 so
that ^Z is now detected correctly as ^<LETTER>.
Additionally, it rephrases the ^<NUMBER> formula for clarity.
the slider on the touch bar was always updated when any of the related
properties changed their value. this is partially dependent on the
refresh rate of the video, in the case of time-pos. too many updates to
touch bar impact the render performance.
to prevent this we only update the slider when necessary, when the touch
bar or the touch bar item is visible. the touch bar items only need a
granularity of seconds without any decimals, but the time-pos property
provides a granularity with decimals. we floor those values and only
update the touch bar items when we have at least a 1 second difference.
we also check for the visibility of the touch bar and its items.
