From 435285bd82a9356b8e13f83cee77a2db4a0e7f0e Mon Sep 17 00:00:00 2001 From: Ævar Arnfjörð Bjarmason Date: Tue, 8 Nov 2022 15:10:34 +0100 Subject: submodule--helper: fix a memory leak in "status" MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The "status" sub-command was leaking the "struct strvec" it was setting up for the reasons explained in f92dbdbc6a8 (revisions API: don't leak memory on argv elements that need free()-ing, 2022-08-02), so let's use the "free_removed_argv_elements" option to setup_revisions() to fix the leak. Even if we did that, clobbering the "diff_files_args.nr" with the return value of setup_revisions() would leave leaks in place, but we can just stop clobbering it. Ever since that code was added in a9f8a37584a (submodule: port submodule subcommand 'status' from shell to C, 2017-10-06) we've had no reason to modify the "nr" member ("argc" at the time): The next use of "diff_files_args" after this is the "strvec_clear()" at the end of the function.
