pandas 3.0.5 is on PyPI without a riscv64 wheel yet, so unconstrained pip resolution picks its sdist and fails to build it (no meson-python in the test virtualenv). PIP_ONLY_BINARY=numpy,pandas keeps resolution on the newest version that has a riscv64 wheel on our registry.

ta-lib0.7.1Compiles a Cython wrapper (
talib._ta_lib) around the TA-Lib C library, which the build fetches and compiles from source at build time. Upstream publishes no riscv64 wheel.Mirrors upstream's
wheels.ymlLinux job.Differs from upstream
CIBW_SKIPexcludes them too..tar.gzinstead of.zip- avoids an extraunzipdependency.Matrix: cp312/cp313/cp314 (no cp314t; see above).
Testing
polars/maturinand ignorestests/test_polars.py- no riscv64 polars wheel exists to install.PIP_ONLY_BINARY=numpy,pandas- unconstrained resolution picked pandas' latest sdist-only release.License: Wheel bundles the TA-Lib C library (BSD-3-Clause); upstream's
license-fileslist doesn't cover it, so the build widens it and drops the library'sLICENSEalongside ta-lib-python's own.Patches
0001-Widen-license-files-to-cover-the-vendored-TA-Lib-C-license.patch- Upstream-Status: To upstream. Without it the wheel ships only ta-lib-python's own LICENSE, missing the vendored C library's notice. Reproduces on any arch.Built on cp312/cp313/cp314-manylinux_riscv64; 39 passed, 3 deselected on each.
