GIT_TEST_SPLIT_INDEX=<boolean> forces split-index mode on the whole
test suite. Accept any boolean values that are accepted by git-config.
+GIT_TEST_PROTOCOL_VERSION=<n>, when set, overrides the
+'protocol.version' setting to n if it is less than n.
+
GIT_TEST_FULL_IN_PACK_ARRAY=<boolean> exercises the uncommon
pack-objects code path where there are more than 1024 packs even if
the actual number of packs in repository is below this limit. Accept
GIT_TEST_PRELOAD_INDEX=<boolean> exercises the preload-index code path
by overriding the minimum number of cache entries required per thread.
-GIT_TEST_REBASE_USE_BUILTIN=<boolean>, when false, disables the
-builtin version of git-rebase. See 'rebase.useBuiltin' in
-git-config(1).
-
GIT_TEST_INDEX_THREADS=<n> enables exercising the multi-threaded loading
of the index for the whole test suite by bypassing the default number of
cache entries and thread minimums. Setting this to 1 will make the
test_oid_init or test_oid_cache. Providing an unknown key is an
error.
+ - yes [<string>]
+
+ This is often seen in modern UNIX but some platforms lack it, so
+ the test harness overrides the platform implementation with a
+ more limited one. Use this only when feeding a handful lines of
+ output to the downstream---unlike the real version, it generates
+ only up to 99 lines.
