As part of preparing for Python 3.12 in Debian, I've uploaded cython 3 to experimental.
I did some test-building of reverse dependencies, and quite a lot of them fail. Out of 291 packages that build-depend on cython3: 104 attempted <- FTBFS 6 given-back <- build-deps aren't installable 1 skipped <- not for arm64 180 successful https://people.debian.org/~stefanor/cython3/cython-3.0.5/summary.txt https://people.debian.org/~stefanor/cython3/cython-3.0.5/stats.txt I re-tried those "attempted" failures, with cython 0.29.36 to find the regressions and: 32 attempted 1 given-back 71 successful https://people.debian.org/~stefanor/cython3/cython-0.29.36/summary.txt https://people.debian.org/~stefanor/cython3/cython-0.29.36/stats.txt So, that's 71 regressions with cython3. dd-list below. Please help us port to cython 3. If this isn't possible, Graham is preparing a cython-legacy package, to help the stragglers. But we're expecting that this won't have great Python 3.12 support... https://ftp-master.debian.org/new/cython-legacy_0.29.36-1~exp1.html Stefano Regression dd-list: Adrian Vondendriesch <adrian.vondendrie...@credativ.de> peewee (U) Alastair McKinstry <mckins...@debian.org> adios Andreas Tille <ti...@debian.org> atropos (U) macs (U) python-cykhash (U) python-cytoolz (U) python-skbio (U) python-srsly (U) python-thinc (U) tombo (U) Anton Gladky <gl...@debian.org> sfepy (U) Antonio Valentino <antonio.valent...@tiscali.it> cyarray (U) pysph (U) python-ltfatpy (U) pyzoltan (U) B.
