Summary

When pypatchmatch's C extension fails to build, patchmatch.patch_match logs an installation-help URL that is hard-coded in pypatchmatch 1.0.2 and now resolves to a 404 (the docs page moved). Failed builds therefore pointed users at a dead link.

PatchMatch now drops only that stale guidance record at pypatchmatch's source logger (before the import that emits it) and logs the current installation help location instead. The compile error detail pypatchmatch reports is kept, and the success path is unchanged. A follow-up URL fix in PyPatchMatch would let the filter be removed.

QA Instructions

Reproduction of the issue's message on unmodified main (pypatchmatch 1.0.2, forced make failure):

>> patchmatch.patch_match: ERROR - patchmatch failed to load or compile (Command 'make clean && make' returned non-zero exit status 2.).
>> patchmatch.patch_match: INFO - Refer to https://invoke-ai.github.io/InvokeAI/installation/060_INSTALL_PATCHMATCH/ for installation instructions.

Same command on this branch:

>> patchmatch.patch_match: ERROR - patchmatch failed to load or compile (Command 'make clean && make' returned non-zero exit status 2.).
[InvokeAI]::INFO --> Patchmatch not loaded (nonfatal)
[InvokeAI]::INFO --> Refer to https://invoke.ai/configuration/patchmatch/#installation for installation instructions.

The stale URL is gone from the output and the compile error detail survives.

• Regression test, unmodified main (RED): uv run --no-sync pytest tests/backend/image_util/test_patchmatch.py fails asserting the stale URL is not emitted — captured output contains Refer to https://invoke-ai.github.io/InvokeAI/installation/060_INSTALL_PATCHMATCH/ for installation instructions.
• Same command on this branch (GREEN): 2 passed.
• uv tool run ruff@0.11.2 check and format --check on both changed paths: passed.
• Family E2E not run: the change only adjusts load-failure log output; no model computation or loading behavior is touched.

Review

No material findings in self-review. The filter matches on the exact stale URL only, so any other pypatchmatch log record (including the compile error) passes through unchanged.
