Hello All,
finally I figured out a way to implement compression (gz) with the help
of the zlib library rather than through gzip pipes. So snow Sage no more
emits failures concerning GAP. Please find in attachment a patch that replaces
gzip pipes with zlib high level functions, as well concomitant patches.
I have also attached an updated d/p/series files: note that the patch
d/p/fix-compressed-six-files is no more necessary and that some autoconf
scripts have to be regenerated (I followed the hint given by dpkg-builpackage).
The material could not be deposited at Alioth as there is no GAP repository
there.
On the other hand, I have just uploaded the source ball, the debian stuff
and the debballs at the Sage repository deb-sci-sage (see the Debain Sage page
[1] for more inrmation); therefore it can be easily tested within a schroot
environment.
At last, as the main patch, namely fix-zlib-stringfile, slightly improves
the GAP kernel itself, it must also be applied to the libGAP package:
I will do if it is effectively applied to GAP.
Looking forward for comments.
Thanks,
Jerome

Description: zlib support
Uncompressing .gz files on the fly through pipes causes the doctests failures
related to GAP. This patch suggest to uncompress directly with zlib to avoid
the underlying EPIPE signal mess that creates `Boken pipes'. The zlib support
is implemented as custom stream through the GNU cookie facility. Furhtermore,
besides the .gz compression format, other compression format (e.g., xz) can be
easily compressed.
