2012-02-08tag: do not show non-tag contents with "-n"Libravatar Junio C Hamano1-10/+12
"git tag -n" did not check the type of the object it is reading the top n lines from. At least, avoid showing the beginning of trees and blobs when dealing with lightweight tags that point at them. As the payload of a tag and a commit look similar in that they both start with a header block, which is skipped for the purpose of "-n" output, followed by human readable text, allow the message of commit objects to be shown just like the contents of tag objects. This avoids regression for people who have been using "tag -n" to show the log messages of commits that are pointed at by lightweight tags. Test script is from Jeff King.

2012-02-07drop odd return value semantics from userdiff_configLibravatar Jeff King3-19/+4
When the userdiff_config function was introduced in be58e70 (diff: unify external diff and funcname parsing code, 2008-10-05), it used a return value convention unlike any other config callback. Like other callbacks, it used "-1" to signal error. But it returned "1" to indicate that it found something, and "0" otherwise; other callbacks simply returned "0" to indicate that no error occurred. This distinction was necessary at the time, because the userdiff namespace overlapped slightly with the color configuration namespace. So "diff.color.foo" could mean "the 'foo' slot of diff coloring" or "the 'foo' component of the "color" userdiff driver". Because the color-parsing code would die on an unknown color slot, we needed the userdiff code to indicate that it had matched the variable, letting us bypass the color-parsing code entirely. Later, in 8b8e862 (ignore unknown color configuration, 2009-12-12), the color-parsing code learned to silently ignore unknown slots. This means we no longer need to protect userdiff-matched variables from reaching the color-parsing code. We can therefore change the userdiff_config calling convention to a more normal one. This drops some code from each caller, which is nice. But more importantly, it reduces the cognitive load for readers who may wonder why userdiff_config is unlike every other config callback. There's no need to add a new test confirming that this works; t4020 already contains a test that sets diff.color.external.

2012-02-07add -e: do not show difference in a submodule that is merely dirtyLibravatar Johannes Schindelin1-0/+1
When the HEAD of the submodule matches what is recorded in the index of the superproject, and it has local changes or untracked files, the patch offered by "git add -e" for editing shows a diff like this: diff --git a/submodule b/submodule <header> -deadbeef... +deadbeef...-dirty Because applying such a patch has no effect to the index, this is a useless noise. Generate the patch with IGNORE_DIRTY_SUBMODULES flag to prevent such a change from getting reported. This patch also loses the "-dirty" suffix from the output when the HEAD of the submodule is different from what is in the index of the superproject. As such dirtiness expressed by the suffix does not affect the result of the patch application at all, there is no information lost if we remove it. The user could still run "git status" before "git add -e" if s/he cares about the dirtiness.

Running "git checkout -b another" immediately after "git init" when you do not even have a commit on 'master' fails with: $ git checkout -b another fatal: You are on a branch yet to be born This is unnecessary, if we redefine "git checkout -b $name" that does not take any $start_point (which has to be a commit) as "I want to check out a new branch $name from the state I am in".

2012-02-06tag: die when listing missing or corrupt objectsLibravatar Jeff King1-1/+5
We don't usually bother looking at tagged objects at all when listing. However, if "-n" is specified, we open the objects to read the annotations of the tags. If we fail to read an object, or if the object has zero length, we simply silently return. The first case is an indication of a broken or corrupt repo, and we should notify the user of the error. The second case is OK to silently ignore; however, the existing code leaked the buffer returned by read_sha1_file.

2012-02-06tag: fix output of "tag -n" when errors occurLibravatar Jeff King1-32/+34
When "git tag" is instructed to print lines from annotated tags via "-n", it first prints the tag name, then attempts to parse and print the lines of the tag object, and then finally adds a trailing newline. If an error occurs, we return early from the function and never print the newline, screwing up the output for the next tag. Let's factor the line-printing into its own function so we can manage the early returns better, and make sure that we always terminate the line.

2012-02-05branch --edit-description: protect against mistyped branch nameLibravatar Junio C Hamano1-0/+15
It is very easy to mistype the branch name when editing its description, e.g. $ git checkout -b my-topic master : work work work : now we are at a good point to switch working something else $ git checkout master : ah, let's write it down before we forget what we were doing $ git branch --edit-description my-tpoic The command does not notice that branch 'my-tpoic' does not exist. It is not lost (it becomes description of an unborn my-tpoic branch), but is not very useful. So detect such a case and error out to reduce the grief factor from this common mistake. This incidentally also errors out --edit-description when the HEAD points at an unborn branch (immediately after "init", or "checkout --orphan"), because at that point, you do not even have any commit that is part of your history and there is no point in describing how this particular branch is different from the branch it forked off of, which is the useful bit of information the branch description is designed to capture. We may want to special case the unborn case later, but that is outside the scope of this patch to prevent more common mistakes before 1.7.9 series gains too much widespread use.

2012-02-05merge: do not create a signed tag merge under --ff-only optionLibravatar Junio C Hamano1-1/+2
Starting at release v1.7.9, if you ask to merge a signed tag, "git merge" always creates a merge commit, even when the tag points at a commit that happens to be a descendant of your current commit. Unfortunately, this interacts rather badly for people who use --ff-only to make sure that their branch is free of local developments. It used to be possible to say: $ git checkout -b frotz v1.7.9~30 $ git merge --ff-only v1.7.9 and expect that the resulting tip of frotz branch matches v1.7.9^0 (aka the commit tagged as v1.7.9), but this fails with the updated Git with: fatal: Not possible to fast-forward, aborting. because a merge that merges v1.7.9 tag to v1.7.9~30 cannot be created by fast forwarding. We could teach users that now they have to do $ git merge --ff-only v1.7.9^0 but it is far more pleasant for users if we DWIMmed this ourselves. When an integrator pulls in a topic from a lieutenant via a signed tag, even when the work done by the lieutenant happens to fast-forward, the integrator wants to have a merge record, so the integrator will not be asking for --ff-only when running "git pull" in such a case. Therefore, this change should not regress the support for the use case v1.7.9 wanted to add. Signed-off-by: Junio C Hamano <gitster@pobox.com>

2012-02-03parse_date(): '@' prefix forces git-timestampLibravatar Junio C Hamano1-0/+6
The only place that the issue this series addresses was observed where we read "cat-file commit" output and put it in GIT_AUTHOR_DATE in order to replay a commit with an ancient timestamp. With the previous patch alone, "git commit --date='20100917 +0900'" can be misinterpreted to mean an ancient timestamp, not September in year 2010. Guard this codepath by requring an extra '@' in front of the raw git timestamp on the parsing side. This of course needs to be compensated by updating get_author_ident_from_commit and the code for "git commit --amend" to prepend '@' to the string read from the existing commit in the GIT_AUTHOR_DATE environment variable.

2012-01-31merge: add instructions to the commit message when editingLibravatar Thomas Rast1-0/+10
Before f824628 (merge: use editor by default in interactive sessions, 2012-01-10), git-merge only started an editor if the user explicitly asked for it with --edit. Thus it seemed unlikely that the user would need extra guidance. After f824628 the _normal_ thing is to start an editor. Give at least an indication of why we are doing it. The sentence about justification is one of the few things about standard git that are not agnostic to the workflow that the user chose. However, f824628 was proposed by Linus specifically to discourage users from merging unrelated upstream progress into topic branches. So we may as well take another step in the same direction.

2012-01-24clone: fix up delay cloning conditionsLibravatar Nguyễn Thái Ngọc Duy2-8/+14
6f48d39 (clone: delay cloning until after remote HEAD checking - 2012-01-16) allows us to perform some checks on remote refs before the actual cloning happens. But not all transport types support this. Remote helper with "import" capability will not return complete ref information until fetch is performed and therefore the clone cannot be delayed. foreign_vcs field in struct remote was used to detect this kind of transport and save the result. This is a mistake because foreign_vcs is designed to override url-based transport detection. As a result, if the same "struct transport *" object is used on many different urls and one of them attached remote transport, the following urls will be mistakenly attached to the same transport. This fault is worked around by dad0b3d (push: do not let configured foreign-vcs permanently clobbered - 2012-01-23) To fix this, detect incomplete refs from transport_get_remote_refs() by SHA-1. Incomplete ones must have null SHA-1 (*). Then revert changes related to foreign_cvs field in 6f48d39 and dad0b3d. A good thing from this change is that cloning smart http transport can also be delayed. Earlier it falls into the same category "remote transport, no delay". (*) Theoretically if one of the remote refs happens to have null SHA-1, it will trigger false alarm and the clone will not be delayed. But that chance may be too small for us to pay attention to.

2012-01-23push: do not let configured foreign-vcs permanently clobberedLibravatar Junio C Hamano1-0/+2
Recently, 6f48d39 (clone: delay cloning until after remote HEAD checking, 2012-01-16) tried to record if a remote helper needs to be called after parsing the remote when transport_get() is called, by overwriting the field meant to store the configured remote helper name in the remote structure. This is OK when a remote represents a single remote repository, but fails miserably when pushing to locations with multiple URLs, like this: $ cat .git/config [remote "origin"] url = https://code.google.com/p/git-htmldocs/ url = github.com:gitster/git-htmldocs.git push = refs/heads/master:refs/heads/master $ git push The second url that is supposed to use the git-over-ssh transport mistakenly use https:// and fails with: error: Couldn't resolve host 'github.com:gitster' while accessing github.com:gitster/git-htmldocs.git/info/refs fatal: HTTP request failed The right solution would probably be to dedicate a separate field to store the detected external helper to be used, which is valid only during a single use of transport until it is disconnected, instead of overwriting foreign_vcs field, but in the meantime, this band-aid should suffice.

2012-01-23merge: use editor by default in interactive sessionsLibravatar Junio C Hamano1-4/+34
Traditionally, a cleanly resolved merge was committed by "git merge" using the auto-generated merge commit log message without invoking the editor. After 5 years of use in the field, it turns out that people perform too many unjustified merges of the upstream history into their topic branches. These merges are not just useless, but they are often not explained well, and making the end result unreadable when it gets time for merging their history back to their upstream. Earlier we added the "--edit" option to the command, so that people can edit the log message to explain and justify their merge commits. Let's take it one step further and spawn the editor by default when we are in an interactive session (i.e. the standard input and the standard output are pointing at the same tty device). There may be existing scripts that leave the standard input and the standard output of the "git merge" connected to whatever environment the scripts were started, and such invocation might trigger the above "interactive session" heuristics. GIT_MERGE_AUTOEDIT environment variable can be set to "no" at the beginning of such scripts to use the historical behaviour while the script runs. Note that this backward compatibility is meant only for scripts, and we deliberately do *not* support "merge.edit = yes/no/auto" configuration option to allow people to keep the historical behaviour.

2012-01-23grep: fix -l/-L interaction with decoration linesLibravatar Albert Yale1-2/+3
In threaded mode, git-grep emits file breaks (enabled with context, -W and --break) into the accumulation buffers even if they are not required. The output collection thread then uses skip_first_line to skip the first such line in the output, which would otherwise be at the very top. This is wrong when the user also specified -l/-L/-c, in which case every line is relevant. While arguably giving these options together doesn't make any sense, git-grep has always quietly accepted it. So do not skip anything in these cases.

write_remote_refs() creates new packed refs from references obtained from the remote repository, which is "out of thin air" as far as the local repository is concerned. Previously it did this by creating "extra" refs, then calling pack_refs() to bake them into the packed-refs file. Instead, create packed refs (in the packed reference cache) directly, then call pack_refs(). Aside from being more logical, this is another step towards removing extra refs entirely.
