checkout: fix "branch info" memory leaks The "checkout" command is one of the main sources of leaks in the test suite, let's fix the common ones by not leaking from the "struct branch_info". Doing this is rather straightforward, albeit verbose, we need to xstrdup() constant strings going into the struct, and free() the ones we clobber as we go along. This also means that we can delete previous partial leak fixes in this area, i.e. the "path_to_free" accounting added by 96ec7b1e708 (Convert resolve_ref+xstrdup to new resolve_refdup function, 2011-12-13). There was some discussion about whether "we should retain the "const char *" here and cast at free() time, or have it be a "char *". Since this is not a public API with any sort of API boundary let's use "char *", as is already being done for the "refname" member of the same struct. The tests to mark as passing were found with: rm .prove; GIT_SKIP_TESTS=t0027 prove -j8 --state=save t[0-9]*.sh :: --immediate # apply & compile this change prove -j8 --state=failed :: --immediate I.e. the ones that were newly passing when the --state=failed command was run. I left out "t3040-subprojects-basic.sh" and "t4131-apply-fake-ancestor.sh" to to optimization-level related differences similar to the ones noted in[1], except that these would be something the current 'linux-leaks' job would run into. 1. https://lore.kernel.org/git/cover-v3-0.6-00000000000-20211022T175227Z-avarab@gmail.com/ Signed-off-by: Ævar Arnfjörð Bjarmason <avarab@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
