audio and MIDI files irreversibly deleted from disk

[Kaj Ailomaa]

[Impact]

Unfortunately I do not have any hard data on this. I can only quote the ardour development team on the last release of ardour3:

"Ardour 3.5.403 is (yet another) CRITICAL bug fix release. ALL USERS ARE RECOMMENDED TO UPGRADE. Additionally, ALL LINUX DISTRIBUTIONS SHOULD IMMEDIATELY UPGRADE/UPDATE TO THIS RELEASE. Distributing earlier versions of 3.5 at this point is irresponsible and risks our users' data.

As with 3.5.380, this release includes several more absolutely vital fixes for bugs could lead to audio and MIDI files being irreversibly deleted from disk.

We still do not know precisely how these losses happened - no user ever found a reliable recipe to recreate all of them - but reports from several different users did lead to a careful code review which uncovered some potential for file loss. "

[Test Case]

Since reproducing seemed difficult, I never tried. I can only refer to the quote above.

[Regression Potential]

Regression potential should be small. This is not a major update. The update I am proposing (ardour3 in vivid) is also the last update ever for ardour3, since ardour4 is now out.

NOTE TO SRU TEAM:
A backport SRU was chosen since the only packaging changes were to parallelize the build, fix slow arches timing out, and one more data loss bug. There are no reverse dependencies (just the Ubuntu Studio meta package) and this gets us in sync with jessie.

[Kaj Ailomaa (zequence)]

This bug affects Trusty and Utopic only.

[Launchpad Janitor (janitor)]

Status changed to 'Confirmed' because the bug affects multiple users.

[Kaj Ailomaa (zequence)]

May I propose a full backport SRU?

No change backports from vivid uploaded to trusty and utopic, awaiting SRU review
