mxml 4 is binary and source incompatible with 3, and there is no easy way to
stay compatible with both. Not great for a library. So replace with libxml2,
hopefully that is more stable. Also means we can get rid of all the mxml hacks
Despite that it seemingly supports multithreading it picks threads that are
busy, and not sure how that can be prevented. Also libevhtp is currently
unmaintained.
Replacing the antlr parsers solves multiple issues:
- Build warnings (issue #307)
- Build hacks: "-Xconversiontimeout 30000" and other Makefile magic
- Incorrect parsing of daap queries with sql wildcards (like 'tag:*tes%t_ng*')
- Infinite recursion/memory/CPU (issue #570 and #1248)
- systemd service file workarounds due to memory/CPU issue
- ANTLR3 being replaced with ANTLR4 (that doesn't support C file generation)
- Runtime dependency on antlr library
- Difficult installs of ANTLR3 on some systems (special install script)
If --enable-install-user set add owntone system user and group (unless other
user/group specified with --with-user or --with-group). The user will be added
to pulse-access if the group is present.
Don't overwrite config, it's a pita. Use same solution as shairport-sync where
distros can use --disable-install_conf_file if required.
A './configure --prefix=/usr --sysconfdir=/etc --localstatedir=/var' will
result in service files in /etc/systemd/system, which seems sensible. Package
builds can specify other location, e.g. --with-systemdir=/lib/systemd/system,
or ship their own service file and use --disable-install-systemd.
Also added more cleanup on uninstall - before we where leaving stuff in
/var/cache/owntone + the logs + the pid files.
Select use of either libspotify or librespot-c as streaming backend via config
option.
librespot-c (renamed/improved spotifyc) impl has the following:
- sync interface
- seek support
- honor bitrate config, set client and thread name
- use web access token with "streaming" scope for login
- fix issue with podcast playback
Also say goodbye to file-based Spotify login.
2.10's mxmlDelete memleaks, and mxml is used in many parts of forked-daapd. So
to avoid that we ship upstream's fixed version of mxmlDelete and use that.
