This week I have updated my patch for gettext to target the new version
uploaded to Debian unstable (0.19.5.1-1).
I pushed the updated patch to our git repo:
I have also uploaded the new build to our custom APT repository, and
attached the patch to the open bug:
I have written a patch for the qthelpgenerator tool from qt4-x11 to
honour SOURCE_DATE_EPOCH when embedding timestamps in the generated qch
files (see issue timestamps_in_qch ). The tool qthelpgenerator embeds
timestamps in different places, so in order to find a general solution I
added the method reproducibleDateTime in the class QDateTime which
returns a deterministic date honouring SOURCE_DATE_EPOCH in case the
variable is set. Then I replaced the instances of
QDateTime::currentDateTime() with QDateTime::reproducibleDateTime()
I have pushed the patch to our git repo:
I have also uploaded the build to our custom APT repository, and opened
a bug with the patch in Debian:
And I have also updated the wiki accordingly.
After patching qt4-x11, 3 packages became reproducible in my machine:
qmf didn't become reproducible in Jenkins: there is a weird issue with
having different files in build 1 and 2 (apparently files are missing in
both builds). This may be caused by parallelism issues and needs further
There are still 12 packages that where tagged with timestamps_in_qch
that didn't become reproducible. They are affected by randomness_in_qdoc
. Also some of them show variations in qch files (it seems to be a
history of SQL commands that differ between builds).
I have fixed some individual packages without notes:
Affected by timestamps in zip metadata (timestamps_in_zip issue)
Embedding of dates:
For next week I'll probably look at the randomness_in_qdoc  issue.
