If the current audio file is renamed, the status items are updated to reflect this fact.
After the server process received SIGHUP, changes to the current audio file did not trigger an update of the status items. This has been fixed.

A short series which overhauls the ff server command.

The ff command now accepts a negative argument to instruct the virtual streaming system to jump backwards in the current audio stream. The old syntax (e.g., “ff 30-”) is still supported but it is deprecated and no longer documented. The compatibility code is sheduled for removal after 0.7.0.

A short series which adds options for para_server that allow the user to specify the listening addresses of the passive sockets.

New server options: –listen–address, –http-listen-address and –dccp-listen-address. These options restrict the set of listening addresses of the TCP and DCCP sockets of the server process.

This series introduces lsu.c and lsu.h which contain helpers related to the lopsub library. These helpers are designed to be shared between the executables. The series starts by implementing a generic help command for lopsub suites and converts para_server. Subsequent patches convert audiod and para_play.

The second part of the series adds another lopsub related helper which merges command line options and config file options. Each executable is modified to make use of the new helper, getting rid of quite some code duplication.

The help commands of server, audiod, play now support –long. By default, the short help is shown.

The code to merge the command line options with the config file options has been consolidated.

Stuff in here is too small to get its own topic branch, and safe enough to be applied to master without cooking in next.

merge date: Sun, 20 May 2018 11:38:11 +0200
rebase count: 42

A quick hack for a screen saver which shows the cover art of the current audio file in an X window and slowly distorts the image, using several transformations provided by the Imagemagick library. Psychedelic and funny to watch.

Not yet integrated in the build system, and definitely quite buggy but could be made to work reliably.
