2012-05-25Merge branch 'ap/checkout-no-progress-for-non-tty'Libravatar Junio C Hamano1-2/+2
The progress indicator for a large "git checkout" was sent to stderr even if it is not a terminal.
2012-05-24checkout: no progress messages if !isatty(2).Libravatar Avery Pennarun1-2/+2
If stderr isn't a tty, we shouldn't be printing incremental progress messages. In particular, this affects 'git checkout -f . >&logfile' unless you provided -q. And git-new-workdir has no way to provide -q. It would probably be better to have progress.c check isatty(2) all the time, but that wouldn't allow things like 'git push --progress' to force progress reporting to on, so I won't try to solve the general case right now. Actual fix suggested by Jeff King. Signed-off-by: Avery Pennarun <apenwarr@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>

When checking out another commit from an already detached state, we used to report all commits that are not reachable from any of the refs as lossage, but some of them might be reachable from the new HEAD, and there is no need to warn about them.

2012-05-08checkout: do not corrupt HEAD on empty repoLibravatar Erik Faye-Lund1-1/+1
In abe1998 ("git checkout -b: allow switching out of an unborn branch"), a code-path overly-optimisticly assumed that a branch-name was specified. This is not always the case, and as a result a NULL-pointer was attempted printed to .git/HEAD. This could lead to at least two different failure modes: 1) vsnprintf formated the NULL-string as something useful (e.g "(null)") 2) vsnprintf crashed Neither were very convenient for formatting a new HEAD-reference. To fix this, reintroduce some strictness so we only take this new codepath if a banch-name was specified.

2012-05-04checkout (detached): truncate list of orphaned commits at the new HEADLibravatar Johannes Sixt1-6/+7
When git checkout switches from a detached HEAD to any other commit, then all orphaned commits were listed in a warning: Warning: you are leaving 2 commits behind...: a5e5396 another fixup 6aa1af6 fixup foo But if the new commit is actually one from this list (6aa1af6 in this example), then the list in the warning can be truncated at the new HEAD, because history beginning at HEAD is not "left behind".

2012-03-26checkout: suppress tracking message with "-q"Libravatar Jeff King1-0/+1
Like the "switched to..." message (which is already suppressed by "-q"), this message is purely informational. Let's silence it if the user asked us to be quiet. This patch is slightly more than a one-liner, because we have to teach create_branch to propagate the flag all the way down to install_branch_config.

2011-12-05Copy resolve_ref() return value for longer useLibravatar Nguyễn Thái Ngọc Duy1-1/+3
resolve_ref() may return a pointer to a static buffer. Callers that use this value longer than a couple of statements should copy the value to avoid some hidden resolve_ref() call that may change the static buffer's value. The bug found by Tony Wang <wwwjfy@gmail.com> in builtin/merge.c demonstrates this. The first call is in cmd_merge() branch = resolve_ref("HEAD", head_sha1, 0, &flag); Then deep in lookup_commit_or_die() a few lines after, resolve_ref() may be called again and destroy "branch". lookup_commit_or_die lookup_commit_reference lookup_commit_reference_gently parse_object lookup_replace_object do_lookup_replace_object prepare_replace_object for_each_replace_ref do_for_each_ref get_loose_refs get_ref_dir get_ref_dir resolve_ref All call sites are checked and made sure that xstrdup() is called if the value should be saved.

2011-11-28checkout,merge: disallow overwriting ignored files with --no-overwrite-ignoreLibravatar Nguyễn Thái Ngọc Duy1-3/+8
Ignored files usually are generated files (e.g. .o files) and can be safely discarded. However sometimes users may have important files in working directory, but still want a clean "git status", so they mark them as ignored files. But in this case, these files should not be overwritten without asking first. Enable this use case with --no-overwrite-ignore, where git only sees tracked and untracked files, no ignored files. Those who mix discardable ignored files with important ones may have to sort it out themselves.

Back in 1127148 (Loosen "working file will be lost" check in Porcelain-ish - 2006-12-04), git-checkout.sh learned to quietly overwrite ignored files. Howver the code only took .gitignore files into account. Standard ignored files include all specified in .gitignore files in working directory _and_ $GIT_DIR/info/exclude.

2011-11-13Convert many resolve_ref() calls to read_ref*() and ref_exists()Libravatar Nguyễn Thái Ngọc Duy1-2/+2
resolve_ref() may return a pointer to a static buffer, which is not safe for long-term use because if another resolve_ref() call happens, the buffer may be changed. Many call sites though do not care about this buffer. They simply check if the return value is NULL or not. Convert all these call sites to new wrappers to reduce resolve_ref() calls from 57 to 34. If we change resolve_ref() prototype later on to avoid passing static buffer out, this helps reduce changes.

2011-10-05Change check_ref_format() to take a flags argumentLibravatar Michael Haggerty1-1/+1
Change check_ref_format() to take a flags argument that indicates what is acceptable in the reference name (analogous to "git check-ref-format"'s "--allow-onelevel" and "--refspec-pattern"). This is more convenient for callers and also fixes a failure in the test suite (and likely elsewhere in the code) by enabling "onelevel" and "refspec-pattern" to be allowed independently of each other. Also rename check_ref_format() to check_refname_format() to make it obvious that it deals with refnames rather than references themselves.

2011-09-30checkout $tree $path: do not clobber local changes in $path not in $treeLibravatar Junio C Hamano1-1/+5
Checking paths out of a tree is (currently) defined to do: - Grab the paths from the named tree that match the given pathspec, and add them to the index; - Check out the contents from the index for paths that match the pathspec to the working tree; and while at it - If the given pathspec did not match anything, suspect a typo from the command line and error out without updating the index nor the working tree. Suppose that the branch you are working on has dir/myfile, and the "other" branch has dir/other but not dir/myfile. Further imagine that you have either modified or removed dir/myfile in your working tree, but you have not run "git add dir/myfile" or "git rm dir/myfile" to tell Git about your local change. Running $ git checkout other dir would add dir/other to the index with the contents taken out of the "other" branch, and check out the paths from the index that match the pathspec "dir", namely, "dir/other" and "dir/myfile", overwriting your local changes to "dir/myfile", even though "other" branch does not even know about that file. Fix it by updating the working tree only with the index entries that was read from the "other" tree. Signed-off-by: Junio C Hamano <gitster@pobox.com>

2011-09-16branch --set-upstream: regression fixLibravatar Junio C Hamano1-1/+2
The "git branch" command, while not in listing mode, calls create_branch() even when the target branch already exists, and it does so even when it is not interested in updating the value of the branch (i.e. the name of the commit object that sits at the tip of the existing branch). This happens when the command is run with "--set-upstream" option. The earlier safety-measure to prevent "git branch -f $branch $commit" from updating the currently checked out branch did not take it into account, and we no longer can update the tracking information of the current branch. Minimally fix this regression by telling the validation code if it is called to really update the value of a potentially existing branch, or if the caller merely is interested in updating auxiliary aspects of a branch.

2011-08-22Prevent force-updating of the current branchLibravatar Conrad Irwin1-9/+3
"git branch -M <foo> <current-branch>" allows updating the current branch which HEAD points, without the necessary house-keeping that git reset normally does to make this operation sensible. It also leaves the reflog in a confusing state (you would be warned when trying to read it). "git checkout -B <current branch> <foo>" is also partly vulnerable to this bug; due to inconsistent pre-flight checks it would perform half of its task and then abort just before rewriting the branch. Again this manifested itself as the index file getting out-of-sync with HEAD. "git branch -f" already guarded against this problem, and aborts with a fatal error. Update "git branch -M", "git checkout -B" and "git branch -f" to share the same check before allowing a branch to be created. These prevent you from updating the current branch. We considered suggesting the use of "git reset" in the failure message but concluded that it was not possible to discern what the user was actually trying to do.

2011-08-11ls-files: fix pathspec display on errorLibravatar Clemens Buchacher1-3/+3
The following sequence of commands reveals an issue with error reporting of relative paths: $ mkdir sub $ cd sub $ git ls-files --error-unmatch ../bbbbb error: pathspec 'b' did not match any file(s) known to git. $ git commit --error-unmatch ../bbbbb error: pathspec 'b' did not match any file(s) known to git. This bug is visible only if the normalized path (i.e., the relative path from the repository root) is longer than the prefix. Otherwise, the code skips over the normalized path and reads from an unused memory location which still contains a leftover of the original command line argument. So instead, use the existing facilities to deal with relative paths correctly. Also fix inconsistency between "checkout" and "commit", e.g. $ cd Documentation $ git checkout nosuch.txt error: pathspec 'Documentation/nosuch.txt' did not match... $ git commit nosuch.txt error: pathspec 'nosuch.txt' did not match... by propagating the prefix down the codepath that reports the error.
