Since ae5a6c3684 (checkout: implement "@{-N}" shortcut name for N-th last branch, 2009-01-17) a branch can be specified using shortcuts like @{-1}. Those shortcuts need to be resolved when considering the arguments. Usage examples: We can modify the description of the previously checked out branch with: $ git branch --edit--description @{-1} We can modify the upstream of the previously checked out branch with: $ git branch --set-upstream-to upstream @{-1} $ git branch --unset-upstream @{-1} Signed-off-by: Rubén Justo --- builtin/branch.c | 29 +++++++++++++++++++++------ t/t3204-branch-name-interpretation.sh | 25 +++++++++++++++++++++++ 2 files changed, 48 insertions(+), 6 deletions(-) diff --git a/builtin/branch.c b/builtin/branch.c index b1f6519cd9..a4069d27e0 100644 --- a/builtin/branch.c +++ b/builtin/branch.c @@ -791,14 +791,17 @@ int cmd_branch(int argc, const char **argv, const char *prefix) } else if (edit_description) { const char *branch_name; struct strbuf branch_ref = STRBUF_INIT; + struct strbuf buf = STRBUF_INIT; int ret = 0; if (!argc) { if (filter.detached) die(_("Cannot give description to detached HEAD")); branch_name = head; - } else if (argc == 1) - branch_name = argv[0]; + } else if (argc == 1) { + strbuf_branchname(&buf, argv[0], INTERPRET_BRANCH_LOCAL); + branch_name = buf.buf; + } else die(_("cannot edit description of more than one branch")); @@ -814,6 +817,7 @@ int cmd_branch(int argc, const char **argv, const char *prefix) ret = 1; strbuf_release(&branch_ref); + strbuf_release(&buf); return ret; } else if (copy) { if (!argc) @@ -834,9 +838,15 @@ int cmd_branch(int argc, const char **argv, const char *prefix) else die(_("too many arguments for a rename operation")); } else if (new_upstream) { - struct branch *branch = branch_get(argv[0]); + struct branch *branch; + struct strbuf buf = STRBUF_INIT; - if (argc > 1) + if (!argc) + branch = branch_get(NULL); + else if (argc == 1) { + strbuf_branchname(&buf, argv[0], INTERPRET_BRANCH_LOCAL); + branch = branch_get(buf.buf); + } else die(_("too many arguments to set new upstream")); if (!branch) { @@ -853,11 +863,17 @@ int cmd_branch(int argc, const char **argv, const char *prefix) dwim_and_setup_tracking(the_repository, branch->name, new_upstream, BRANCH_TRACK_OVERRIDE, quiet); + strbuf_release(&buf); } else if (unset_upstream) { - struct branch *branch = branch_get(argv[0]); + struct branch *branch; struct strbuf buf = STRBUF_INIT; - if (argc > 1) + if (!argc) + branch = branch_get(NULL); + else if (argc == 1) { + strbuf_branchname(&buf, argv[0], INTERPRET_BRANCH_LOCAL); + branch = branch_get(buf.buf); + } else die(_("too many arguments to unset upstream")); if (!branch) { @@ -870,6 +886,7 @@ int cmd_branch(int argc, const char **argv, const char *prefix) if (!branch_has_merge_config(branch)) die(_("Branch '%s' has no upstream information"), branch->name); + strbuf_reset(&buf); strbuf_addf(&buf, "branch.%s.remote", branch->name); git_config_set_multivar(buf.buf, NULL, NULL, CONFIG_FLAGS_MULTI_REPLACE); strbuf_reset(&buf); diff --git a/t/t3204-branch-name-interpretation.sh b/t/t3204-branch-name-interpretation.sh index 993a6b5eff..0a423298d6 100755 --- a/t/t3204-branch-name-interpretation.sh +++ b/t/t3204-branch-name-interpretation.sh @@ -133,4 +133,29 @@ test_expect_success 'checkout does not treat remote @{upstream} as a branch' ' expect_branch HEAD one ' +test_expect_success 'edit-description via @{-1}' ' + git checkout main && + git checkout - && + write_script editor <<-\EOF && + echo "Branch description" >"$1" + EOF + EDITOR=./editor git branch --edit-description @{-1} && + write_script editor <<-\EOF && + git stripspace -s <"$1" >"EDITOR_OUTPUT" + EOF + EDITOR=./editor git branch --edit-description @{-1} && + echo "Branch description" >expect && + test_cmp expect EDITOR_OUTPUT +' + +test_expect_success 'modify branch upstream via "@{-1}" and "@{-1}@{upstream}"' ' + git branch upstream-branch && + git checkout -b upstream-other -t upstream-branch && + git checkout - && + git branch --set-upstream-to @{-1} @{-1}@{upstream} && + test "$(git config branch.upstream-branch.merge)" = "refs/heads/upstream-other" && + git branch --unset-upstream @{-1} && + test_must_fail git config branch.upstream-other.merge +' + test_done -- 2.36.1
