Audacity silently truncates export when disk full

[Chad Hogg]

Binary package hint: audacity

If there is insufficient disk space when exporting a project to WAV, Audacity will simply write as much as there is space available and report that the export was successful. It should instead inform the user that the export failed. This occurs more frequently than you might expect, because Audacity spews large amounts of data to /tmp/ to be able to "undo" edits.

In my particular case, I cannot open a ~800MB WAV file, normalize it, apply a 3dB amplification, and export back to same file despite having more than 25% of my disk (about 3.8GB) available.

Note: This is sort of a specific instance of bug #22842, but the defect is in the individual package, not distribution-wide.

It makes sense, since the result of sf_writef_short / sf_writef_float is never checked in ExportPCM::Export in exportPCM.cpp. Assuming this bug is still present.

Will you upstream this one for me? Hopefully I got the patch tags the way you want them now. Thanks!

Thanks, uploaded it to Debian. The meta-data are formatted correctly. I only shortened the bug link.

Upstream will probably not apply the patch. They want to check the available space before saving the files.

This bug was fixed in the package audacity - 1.3.9-5

---------------
audacity (1.3.9-5) unstable; urgency=low

  * Add debian/patches/disk-full-on-export.patch to show an error message if
    the disk gets full on PCM export; thanks to David Henningsson for the patch
    (LP: #259798).
