stream-inflate: add build-stream-inflate.yml for riscv64 wheels - #1115
Merged
Conversation
The riscv64 build jobs hit the 60-minute wall 40-44% through the 1956-case parametrized fuzz suite; every completed test passed.
cp312/cp313/cp314-musllinux consistently ran ~8x slower than every other combination on this allocation-heavy fuzz suite and did not finish within a 240-minute budget (twice, reproducibly, at the same ~43-44% mark), while cp314t-musllinux and all four manylinux jobs finished cleanly in under 2h15m. Per PEP 703, the free-threaded build (cp314t) replaces pymalloc with mimalloc; the GIL-enabled builds keep pymalloc, which delegates large allocations straight to the platform malloc - musl's being markedly slower than glibc's here. Not fixable in this workflow; dropping musllinux per the skill's "if the musl jobs fail with no obvious fix, strip them" guidance.
