Hello,
I have uploaded lios/2.7.2-5 to unstable, to hopefully make it to
bookworm.
[ Reason ]
As reported on #990805 and #1033024, in the current version of lios when
opening the general preferences dialog box, lios stays stuck for a
couple minutes. This happens only when the espeak-ng package is
installed, in which case there are thousands of voices available for
the speech configuration part of this dialog box, thus making it very
long to load.
Upstream fixed the issue without telling me, we eventually found it was
fixed in a more recent upstream snapshot, and I picked up the upstream
commit for this, included in lios/2.7.2-5. The idea of the fix is to
separate the voices by language, so that the user first chooses among a
few hundred languages, and then chooses a voice person. This is enough
to make the dialog box load in a snap.
[ Impact ]
Without this new version, users will have to either remove the espeak-ng
package (but lios users are most often blind users so they do need it),
or they have to wait for several minutes when they want to change some
general preference.
[ Tests ]
This was tested manually as fixing the issue.
[ Risks ]
The code is relatively simple: in lios/speech.py, instead of having
list_voices return a plain list, it creates a dictionary sorted by
language. lios/preferences.py then contains an additional combobox, and
the logic is reworked around these to implement the two-step selection.
The upstream commit also includes selecting a default voice according to
the current locale. I prefered to avoid splitting it from the upstream
commit since the two parts seem related.
[ Checklist ]
[X] all changes are documented in the d/changelog
[X] I reviewed all changes and I approve them
[X] attach debdiff against the package in testing
