gh-151949: Fix Sphinx reference warnings in Doc/library/lzma.rst#153878
Merged
Conversation
The lzma module constants (FORMAT_*, CHECK_*, PRESET_*, FILTER_*, MODE_* and MF_*) were referenced with the :const: role throughout the module documentation but were never defined as reference targets, producing "reference target not found" warnings under nitpicky mode. Document these public constants with .. data:: directives, following the convention used by the signal, socket and ssl modules, so the existing references resolve. The now-redundant inline descriptions of the format and check constants are condensed into linked references.

The
lzmamodule constants (FORMAT_*,CHECK_*,PRESET_*, theFILTER_*names,MODE_*andMF_*) were referenced with the:const:role all overDoc/library/lzma.rst, but none of them were actually defined as reference targets. In nitpicky mode this produced 35 "py:const reference target not found" warnings (the full list is in the issue).This documents those constants with
.. data::directives, the same waysignal,socketandsslalready do it, so the existing:const:references resolve to real linked entries. The inline descriptions of the format and check constants inLZMACompressorbecome short linked references, and their full descriptions now live in the new Constants section. The BCJ filter references that are deliberately suppressed (likeFILTER_X86) are left alone, since they don't emit warnings.I checked with a nitpicky docs build (
sphinx-build -n -D nitpicky=1): all 35 warnings fromlzma.rstare gone and no new ones appear.Sub-issue of #151940.
