From: Johannes Schindelin <johannes.schindelin@xxxxxx> Even if we strongly discourage putting credentials into the URLs passed via the command-line, there _is_ support for that, and users _do_ do that. Let's scrub them before writing them to the reflog. Signed-off-by: Johannes Schindelin <johannes.schindelin@xxxxxx> --- Anonymize URLs in the reflog This came up in an internal audit, but we do not consider this to be a big deal: the reflog is local and not really shared with anybody. Changes since v1: * Changed the if...else if...else cadence to move the die() to the last arm * Stopped the memory leak of display_repo (allocated by transport_anonymize_url()) Published-As: https://github.com/gitgitgadget/git/releases/tag/pr-git-797%2Fdscho%2Fanonymize-clone-reflog-v2 Fetch-It-Via: git fetch https://github.com/gitgitgadget/git pr-git-797/dscho/anonymize-clone-reflog-v2 Pull-Request: https://github.com/git/git/pull/797 Range-diff vs v1: 1: 11c0d47c95e ! 1: 933a7353847 clone/fetch: anonymize URLs in the reflog @@ Commit message Signed-off-by: Johannes Schindelin <johannes.schindelin@xxxxxx> ## builtin/clone.c ## -@@ builtin/clone.c: static int path_exists(const char *path) - int cmd_clone(int argc, const char **argv, const char *prefix) +@@ builtin/clone.c: int cmd_clone(int argc, const char **argv, const char *prefix) { int is_bundle = 0, is_local; -- const char *repo_name, *repo, *work_tree, *git_dir; -+ const char *repo_name, *repo, *display_repo, *work_tree, *git_dir; - char *path, *dir; + const char *repo_name, *repo, *work_tree, *git_dir; +- char *path, *dir; ++ char *path, *dir, *display_repo = NULL; int dest_exists; const struct ref *refs, *remote_head; + const struct ref *remote_head_points_at; @@ builtin/clone.c: int cmd_clone(int argc, const char **argv, const char *prefix) - path = get_repo_path(repo_name, &is_bundle); if (path) -- repo = absolute_pathdup(repo_name); -+ display_repo = repo = absolute_pathdup(repo_name); - else if (!strchr(repo_name, ':')) - die(_("repository '%s' does not exist"), repo_name); + repo = absolute_pathdup(repo_name); +- else if (!strchr(repo_name, ':')) +- die(_("repository '%s' does not exist"), repo_name); - else -+ else { ++ else if (strchr(repo_name, ':')) { repo = repo_name; + display_repo = transport_anonymize_url(repo); -+ } ++ } else ++ die(_("repository '%s' does not exist"), repo_name); /* no need to be strict, transport_set_option() will validate it again */ if (option_depth && atoi(option_depth) < 1) @@ builtin/clone.c: int cmd_clone(int argc, const char **argv, const char *prefix) "an empty directory."), dir); - strbuf_addf(&reflog_msg, "clone: from %s", repo); -+ strbuf_addf(&reflog_msg, "clone: from %s", display_repo); ++ strbuf_addf(&reflog_msg, "clone: from %s", ++ display_repo ?
