[Jack-Devel] [jackaudio/jack1] 93bc88: clear unused slave netjack header fields.

by Paul Davis

As most NetJACK header fields are not set by the slave and thus may contain anything (which looks weird on the wire), it makes sense to actively clear the unused fields.

[Jack-Devel] [jackaudio/jack1] 170367: fix 8bit netjack MIDI payload size.

by Paul Davis

MIDI payload size in 8bit netjack MIDI mode is calculated wrongly (assumes 16bit sample size). This bug sits at the decoding end and seems to be without concequences, as the MIDI payload size in 8bit netjack MIDI mode at the encoding end is done right and the decoding buffer thus cannot overflow even with a wrongly calculated MIDI payload size.

[Jack-Devel] Client-Server models are just fine. Please?

by Jörn Nettingsmeier

Hi *! Funny to see the recent activity prompted by Paul's step-down notice. I'm a bit worried to see this flurry of fundamental design discussions about putting everything into some magical lib and whatnot. Client-server thinking is a fundamental prerequisite for keeping one's sanity when using UNIX (and Mac OS X, for that matter), and it even benefits Windows users. Client-server architecture is good. It works. Nothing against automating things, but if your user-friendly application feels it must spawn a jack server for me, it needs to do all of the following: * pop open a notice to the effect that no jack server has been found and does the user want you to do that for her/him? together with a checkbox to not ask again and a notice on how to undo the "don't ask again". * spawn a jackd server and explain to the user how it guessed what configuration to use and how to change that. also point out to the user how to see/modify jack connections with jack_lsp/jack_connect (because they will always be present on any system that has jack) and of course point to user-friendly tools such as JackPilot, qjackctl, or patchage. also tell the user how to access jackd error messages. no votes for implicit magic without being obvious about what's being done. good example of how not to do magic (no systemd bashing here, plz, it's just an example!): i use cd ripping tool "asunder" and tell it to log to /var/log/asunder.log because i suspect hardware failure of a dvdrw drive. no log ever appears. days later, i look through the system journal and see that it has incorporated the asunder log messages. either asunder logs to syslog anyways and hasn't updated its gui to reflect it (then i don't have a case here), or journald has some magic to catch any attempt to start a log in /var/log and reroutes it to the global log. if the latter, then the user-friendly way to do it is to write a stub /var/log/asunder.log that contains a note as to what has happened to the log and where the information is to be found. again: no implicitism without making it obvious what is happening for old people who still think everything is a file. i still think the best way to make jack user-friendly is to quickly educate users how to start a graphical jack config and patching tool, and then start their app. this is the free software community. unless we want to make all our hangouts on IRC, mailing lists, and forums uninhabitable, we MUST NOT DUMB DOWN OUR NEW USERS, and what's worse, annoy old and experienced ones! be friendly, yes, by all means. hide the underlying workings from users and prevent them from understanding them, never. just my few cents, Jörn -- Jörn Nettingsmeier Lortzingstr. 11, 45128 Essen, Tel. +49 177 7937487 Meister für Veranstaltungstechnik (Bühne/Studio) Tonmeister VDT http://stackingdwarves.net

[Jack-Devel] stepping down

by Paul Davis

Sometime in the next two weeks, I will find the time to deal with a variety of pull requests for JACK 1, update some articles on jackaudio.org (notably FAQ stuff), and do a new release of JACK 1. This will be my last work on JACK. The time has come for me to step down from my role as "benign dictator (and jack1 maintainer)". There several reasons for this: * most linux distributions use JACK2 as their default, so JACK1's relevance has diminished. I still believe JACK1 to be a superior choice from some technical perspectives, but there is no doubt that JACK2's integration with dbus and thus its interoperability with PulseAudio has made this the safe and simpler choice for Linux. * I really don't have the time to even think about things related to JACK these days. It does any future development a disservice to have me as the bottleneck, which I effectively am at the moment. * Because 110% of my time is spent on Ardour, the fact that Ardour now has non-JACK audio/MIDI I/O options has diminished the significance of JACK for my own work. * as the years have gone on, although I am still delighted by the technical quality and the conception of JACK, I no longer think that it is a particularly good idea for most users. There are times when it is useful I will continue to pay for the hosting of jackaudio.org (even though JACK2 continues to be distributed, managed and communicated about via other channels), although if someone wanted to migrate this to some other more communitarian platform, we could look into that. I would be happy if someone volunteered to step up as maintainer of JACK1. It would obviously be even better if someone was willing to take the big leap to JACK3, a version that combines all the best parts of JACK1 and JACK2, but I think it is more realistic to accept at this point that this is not going to happen. If nobody does step up, then there is a good chance that JACK1 will become officially unmaintained. This isn't of much consequence, because once the latest pull requests are merged, there won't be any known bugs in the code, and also because not many people use it anymore. This also means, of course, that "maintainer" is not much of a task, should someone feel hesitant about taking it on. --p
