Dear Frederic,
I kindly ask your sponsor the initial upload of the c-blosc2 library.
It is a compression library that in now (since PyTables v3.8) a
dependency of the PyTables package (currently maintained in Debian Science).
An update of debian package for PyTables (currently v3.7) is needed to
support Python 3.12.
Moreover I think that c-blosc2 will soon become a dependency also for zarr.
I have created a repository on salsa
https://salsa.debian.org/science-team/c-blosc2
and the package is now ready to be reviewed and upload.
The ITP bug is #1038443
(https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1038443) and the
upstream repository is on GitHub: https://github.com/Blosc/c-blosc2.
With respect to the initial ITP the package has been now updated to v2.11.2.
After the initial upload I will take care of maintaining the package and
uploading new versions.
kind regards
Antonio

Dear all,
c-blosc2 is "Fast, compressed, persistent binary data store library"
(see details below).
Since v3.8 PyTables (maintained in Debian Science) requires also c-blosc2.
I would like to maintain the package in Debian Science and I'm looking
for a sponsor for the initial upload.
The git repository for the Debian package of c-blosc2 is currently in my
personal area on salsa:
https://salsa.debian.org/antonio.valentino/c-blosc2
I will quickly move it to https://salsa.debian.org/science-team/c-blosc2
as soon as someone accepts to sponsor it.
kind regards
antonio

Version : 2.9.2
Upstream Author : Antonio Valentino <antonio.valent...@tiscali.it>

Programming Lang: C
Description : Fast, compressed, persistent binary data store
library for C
Binary package names: libblosc2-2, libblosc2-dev
Blosc is a high performance compressor optimized for binary data.
It has been designed to transmit data to the processor cache faster
than the traditional, non-compressed, direct memory fetch approach
via a memcpy() OS call. Blosc main goal is not just to reduce the
size of large datasets on-disk or in-memory, but also to accelerate
memory-bound computations.
.
C-Blosc2 is the new major version of C-Blosc, and tries hard to be
backward compatible with both the C-Blosc1 API and its in-memory
format. However, the reverse thing is generally not true for the
format; buffers generated with
C-Blosc2 are not format-compatible with C-Blosc1 (i.e. forward
compatibility is not supported). In case you want to ensure full
API compatibility with C-Blosc1 API, define the BLOSC1_COMPAT symbol.
