People expect the resulting repository to +be smaller than the original, but you need a few more steps to +actually make it smaller, because git tries hard not to lose your +objects until you tell it to. First make sure that: + +* You really removed all variants of a filename, if a blob was moved + over its lifetime. `git log \--name-only \--follow \--all \-- + filename` can help you find renames. + +* You really filtered all refs: use `\--tag-name-filter cat \-- + \--all` when calling git-filter-branch. + +Then there are two ways to get a smaller repository. A safer way is +to clone, that keeps your original intact. + +* Clone it with `git clone +++file:///path/to/repo+++`. The clone + will not have the removed objects. See linkgit:git-clone[1]. (Note + that cloning with a plain path just hardlinks everything!) + +If you really don't want to clone it, for whatever reasons, check the +following points instead (in this order). This is a very destructive +approach, so *make a backup* or go back to cloning it. You have been +warned. + +* Remove the original refs backed up by git-filter-branch: say `git + for-each-ref \--format="%(refname)" refs/original/ | xargs -n 1 git + update-ref -d`. + +* Expire all reflogs with `git reflog expire \--expire=now \--all`. + +* Garbage collect all unreferenced objects with `git gc \--prune=now` + (or if your git-gc is not new enough to support arguments to + `\--prune`, use `git repack -ad; git prune` instead). + + Author ------ Written by Petr "Pasky" Baudis <pasky@suse.cz>, diff --git a/builtin-symbolic-ref.c b/builtin-symbolic-ref.c index cafc4eba7..6ae6bcc0e 100644 --- a/builtin-symbolic-ref.c +++ b/builtin-symbolic-ref.c @@ -45,8 +45,8 @@ int cmd_symbolic_ref(int argc, const char **argv, const char *prefix) break; case 2: if (!strcmp(argv[0], "HEAD") && - prefixcmp(argv[1], "refs/heads/")) - die("Refusing to point HEAD outside of refs/heads/"); + prefixcmp(argv[1], "refs/")) + die("Refusing to point HEAD outside of refs/"); create_symref(argv[0], argv[1], msg); break; default: diff --git a/contrib/completion/git-completion.bash b/contrib/completion/git-completion.bash index f44f63cfe..412d2c0da 100755 --- a/contrib/completion/git-completion.bash +++ b/contrib/completion/git-completion.bash @@ -1196,10 +1196,14 @@ _git_config () __gitcomp "$(__git_merge_strategies)" return ;; - color.branch|color.diff|color.status) + color.branch|color.diff|color.interactive|color.status|color.ui) __gitcomp "always never auto" return ;; + color.pager) + __gitcomp "false true" + return + ;; color.*.*) __gitcomp " normal black red green yellow blue magenta cyan white @@ -1606,7 +1610,7 @@ _git_svn () --follow-parent --authors-file= --repack= --no-metadata --use-svm-props --use-svnsync-props --log-window-size= --no-checkout --quiet - --repack-flags --user-log-author --localtime $remote_opts + --repack-flags --use-log-author --localtime $remote_opts " local init_opts=" --template= --shared= --trunk= --tags= @@ -2326,15 +2326,12 @@ void diff_setup(struct diff_options *options) options->break_opt = -1; options->rename_limit = -1; options->dirstat_percent = 3; - DIFF_OPT_CLR(options, DIRSTAT_CUMULATIVE); options->context = 3; options->change = diff_change; options->add_remove = diff_addremove; if (diff_use_color_default > 0) DIFF_OPT_SET(options, COLOR_DIFF); - else - DIFF_OPT_CLR(options, COLOR_DIFF); options->detect_rename = diff_detect_rename_default; if (!diff_mnemonic_prefix) { diff --git a/t/t1401-symbolic-ref.sh b/t/t1401-symbolic-ref.sh index 569f34177..7fa5f5b22 100755 --- a/t/t1401-symbolic-ref.sh +++ b/t/t1401-symbolic-ref.sh @@ -27,11 +27,6 @@ test_expect_success 'symbolic-ref refuses non-ref for HEAD' ' ' reset_to_sane -test_expect_success 'symbolic-ref refuses non-branch for HEAD' ' - test_must_fail git symbolic-ref HEAD refs/foo -' -reset_to_sane - test_expect_success 'symbolic-ref refuses bare sha1' ' echo content >file && git add file && git commit -m one test_must_fail git symbolic-ref HEAD `git rev-parse HEAD` diff --git a/t/t1500-rev-parse.sh b/t/t1500-rev-parse.sh index 85da4caa7..48ee07779 100755 --- a/t/t1500-rev-parse.sh +++ b/t/t1500-rev-parse.sh @@ -26,21 +26,28 @@ test_rev_parse() { "test '$1' = \"\$(git rev-parse --show-prefix)\"" shift [ $# -eq 0 ] && return + + test_expect_success "$name: git-dir" \ + "test '$1' = \"\$(git rev-parse --git-dir)\"" + shift + [ $# -eq 0 ] && return } -# label is-bare is-inside-git is-inside-work prefix +# label is-bare is-inside-git is-inside-work prefix git-dir + +ROOT=$(pwd) -test_rev_parse toplevel false false true '' +test_rev_parse toplevel false false true '' .git cd .git || exit 1 -test_rev_parse .git/ false true false '' +test_rev_parse .git/ false true false '' . cd objects || exit 1 -test_rev_parse .git/objects/ false true false '' +test_rev_parse .git/objects/ false true false '' "$ROOT/.git" cd ../.. || exit 1 mkdir -p sub/dir || exit 1 cd sub/dir || exit 1 -test_rev_parse subdirectory false false true sub/dir/ +test_rev_parse subdirectory false false true sub/dir/ "$ROOT/.git" cd ../.. || exit 1 git config core.bare true diff --git a/t/t1501-worktree.sh b/t/t1501-worktree.sh index 27dc6c55d..f6a6f839a 100755 --- a/t/t1501-worktree.sh +++ b/t/t1501-worktree.sh @@ -92,13 +92,6 @@ cd sub/dir || exit 1 test_rev_parse 'in repo.git/sub/dir' false true true sub/dir/ cd ../../../.. || exit 1 -test_expect_success 'detecting gitdir when cwd is in a subdir of gitdir' ' - (expected=$(pwd)/repo.git && - cd repo.git/refs && - unset GIT_DIR && - test "$expected" = "$(git rev-parse --git-dir)") -' - test_expect_success 'repo finds its work tree' ' (cd repo.git && : > work/sub/dir/untracked && |
