(As suggested in #17273 (comment))

Once in a while, we skip or xfail tests to quickly restore the CI to the green status, when we either lack the immediate bandwidth to resolve an issue properly, or a fix takes a while etc. Once a proper fix lands, the skip needs to be reverted.
This is a tracking issue to keep track of these skips and their reverts.

TO-DO

• BUG: failing sqrtm regression test #20219
• BUG: scipy.linalg.blas.dnrm2 may return error result when incx < 0 #16930 adds an xfailed test of linalg.blas.nrm2(..., incx=-1). Revisit when minimum openblas is >= 0.3.27. EDIT (June 2025): Revert attempted in ENH: linalg: stop erroring out in dnrm2(..., inc<0) #23162. The problem persists for MacOS 14, and jobs on Ubuntu jammy and noble.

Completed

• TST: stats: silence warnings temporarily #17272 silences warnings produced by stats distributions with implementations from Boost. It needs to be reverted once BUG: stats: distribution methods emit unnecessary warnings from Boost #14901 is resolved.
• TST: linalg: temporarily silence failure in test_solve_discrete_are #17273 skips a test of a discrete Riccatti equation which fails on Cirrus CI. TST: linalg: temporarily silence failure in test_solve_generalized_discrete_are #17525 skips a similar test which fails on some machines. The skips need a revert once TEST/BUG: Tolerance violation in test_solvers::test_solve_discrete_are #16926 is resolved.
• CI: On Azure, pin pytest-xdist to version 2.5.0 #17331 Unpin a CI package dependency of pytest-xdist because of an incompatibility with pytest-cov
• doccer change in python 3.13: BUG: doccer: test_decorator fails with Python 3.13 due to dedented docstring constants #19572 is skipped in CI: Add Linux workflow to test on free-threaded Python builds #20822 (done in MAINT: Unskip scipy.misc.test.test_decorator for Python 3.13+ #21104)
