verify-patch-sanity.py validates every active recipe .patch has internally- consistent hunk line counts — catching the 'malformed patch at line N' failure at commit/CI/preflight time instead of hours into a cook. This cycle hit that class three times (qtwaylandscanner, sddm, xwayland), each only discovered when cookbook tried to apply the patch. Running it across the repo found 29 latent malformed patches (validated against GNU patch: e.g. relibc/P3-sysv-ipc reproduces 'malformed patch at line 22'). They were harmless only because they sit in vendored recipes (baked, not re- applied) — but would fail on any version-bump re-derivation. --fix recounts the hunk headers (body untouched) and repaired all 29. Wired into build-preflight.sh (Phase 1.0D) and redbear-ci.yml, with a unit test (test-patch-sanity.sh). Skips archived/legacy trees and unvalidatable formats (empty placeholders, bare-@@ git hunks).

# The way you use this is you create a script that takes in as its first
|
|
# argument a count. The script passes into LLVM the count via a command
|
|
# line flag that disables a pass after LLVM has run after the pass has
|
|
# run for count number of times. Then the script invokes a test of some
|
|
# sort and indicates whether LLVM successfully compiled the test via the
|
|
# scripts exit status. Then you invoke bisect as follows:
|
|
#
|
|
# bisect --start=<start_num> --end=<end_num> ./script.sh "%(count)s"
|
|
#
|
|
# And bisect will continually call ./script.sh with various counts using
|
|
# the exit status to determine success and failure.
