35f43dfacb added a system to write resume files for redirects, i.e.
directories and playlists that mpv expands.
It creates a resume file for each redirect, and for the first redirect
only, it writes a resume file for each segment of its path, without even
converting it to an absolute path if it's relative. This is incomplete:
mpv 'Iron Maiden/1982 The Number of the Beast/8 Hallowed Be Thy Name.mp3'
This doesn't save any redirect entry.
mpv --directory-mode=recursive 'Iron Maiden', then quit-watch-later on
Hallowed Be Thy Name
This saves a redirect entry for "Iron Maiden", but not for "1982 The
Number of the Beast". It doesn't save redirect entries for the
directories above "Iron Maiden" either because "Iron Maiden" isn't
converted to an absolute path.
In both of these cases mpv --directory-mode=lazy 'Iron Maiden' won't
resume from "Hallowed Be Thy Name" because "1982 The Number of the
Beast" isn't the first subdirectory and there is no redirect entry for
it.
503dada42f made mpv recursively expand subdirectories precisely to fix
this, and f266eadf1e added back an option not to expand them. But if we
fix how redirect entries are stored, we can make the superior
--directory-mode=lazy (because it's faster and doesn't result in massive
playlists) the default, and also ensure that mpv will resume playback
even when you quit-watch-later a file without redirects and then play
the directories above it.
Fix this by always creating redirect entries for all segments of the absolute
path of the file, so that both
mpv 'Iron Maiden/1982 The Number of the Beast/8 Hallowed Be Thy Name.mp3'
and
mpv --directory-mode=lazy 'Iron Maiden'
will create redirect entries for
/$USER
/$USER/music
/$USER/music/Iron Maiden
/$USER/music/Iron Maiden/1982 The Number of the Beast
making mpv --directory-mode=lazy "Iron Maiden" resume from
"Hallowed Be Thy Name".
This commit also makes mpv delete the redirect entries of parent
directories when resuming playback, because if for example you have a
playlist with all the songs in a discography:
1980 Iron Maiden/1 Prowler.mp3
1980 Iron Maiden/2 Remember Tomorrow.mp3
...
1981 Killers/1 The Ides of March.mp3
1981 Killers/2 Wrathchild.mp3
...
Now mpv will eventually create redirect entries for every album. If you
later decide to play the directories instead and there are 20 albums,
you would have to do mpv * 20 times to clear all the redirect entries.
Currently, nothing new is actually implemented but the idea is simply to
just pass a type string all the way up from mp_find_user_file down to
actually getting the platform path. This allows for selecting different
directories besides the user's native config directory. See the next
commit for an implementation.
The path functions need to access the option that forces non-default
config directories. Just add it as a field to mpv_global - it seems
justified. The accessed options were always enforced as immutable after
init, so there's not much of a change.
The history goes back to 2001 or so, but everyone involved with still
existing code has agreed.
One person who could not be reached yet (elevengu) has changes in this,
which as far as I can tell were overwritten anyway at a later point.
If you do "mpv /bla/", and then branch out into sub-directories using
playlist navigation, and then used quit and watch later, then playing
the same directory did not resume from the previous point. This was
because resuming is based on the path hash, so a path prefix can't be
detected when resuming the parent directory.
Solve this by writing each path prefix when playing directories is
involved. (This includes all parent paths, so interestingly, "mpv /"
would also resume in the above example.)
Something like this was requested multiple times, and I want it too.
mp_find_config_file() will print the filename lookup and its result in
verbose mode. This is wanted, but gets inconvenient when it is done for
every playlist entry (for resuming).
Lookup the watch_later subdir only once and cache the result instead.
This drops the logic for loading the resume file from other locations,
which should generally be unnecessary, though might lead to confusion if
the user has mixed old and new config paths (which the user shouldn't).
Also add a mp_find_user_config_file() function for a more
straightforward and reliable way to get actual local configpaths,
instead of possibly global and unwritable locations.
Also, for symmetry, check the resume option in mp_load_playback_resume()
just like mp_check_playlist_resume() does.
Actually, it's pretty simple to look for multiple filenames at once,
since mp_find_all_config_files() is already a bit "special" anyway.
See #1569. Reverts most of commit db167cd4 (keeps osx-bundle.conf).
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.
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()
Closes#864, #109.

Including the "." in the returned extension was too inconvenient. I
think originally, the semantics were supposed to work like in Python,
but screw this.
Also, return NULL instead of "" on failure (which is what its only user
actually seems to expect).
There's a single mp_msg() in path.c, but all path lookup functions seem
to depend on it, so we get a rat-tail of stuff we have to change. This
is probably a good thing though, because we can have the path lookup
functions also access options, so we could allow overriding the default
config path, or ignore the MPV_HOME environment variable, and such
things.
Also take the chance to consistently add talloc_ctx parameters to the
path lookup functions.
Also, this change causes a big mess on configfiles.c. It's the same
issue: everything suddenly needs a (different) context argument. Make it
less wild by providing a mp_load_auto_profiles() function, which
isolates most of it to configfiles.c.
Since m_option.h and options.h are extremely often included, a lot of
files have to be changed.
Moving path.c/h to options/ is a bit questionable, but since this is
mainly about access to config files (which are also handled in
options/), it's probably ok.
