* pull: allow "git pull origin $something:$current_branch" into an unborn branchJunio C Hamano2008-10-17
| | | | | | | | | | | | | | | | | | Some misguided documents floating on the Net suggest this sequence: mkdir newdir && cd newdir git init git remote add origin $url git pull origin master:master "git pull" has known about misguided "pull" that lets the underlying fetch update the current branch for a long time. It also has known about "git pull origin master" into a branch yet to be born. These two workarounds however were not aware of the existence of each other and did not work well together. This fixes it. Signed-off-by: Junio C Hamano <gitster@pobox.com>

* Make usage strings dash-lessStephan Beyer2008-07-13
| | | | | | | | | | | | | | | When you misuse a git command, you are shown the usage string. But this is currently shown in the dashed form. So if you just copy what you see, it will not work, when the dashed form is no longer supported. This patch makes git commands show the dash-less version. For shell scripts that do not specify OPTIONS_SPEC, git-sh-setup.sh generates a dash-less usage string now.

* pull --rebase: exit early when the working directory is dirtyJohannes Schindelin2008-05-22
| | | | | | | | | | | When rebasing fails during "pull --rebase", you cannot just clean up the working directory and call "pull --rebase" again, since the remote branch was already fetched. Therefore, die early when the working directory is dirty. Signed-off-by: Johannes Schindelin <johannes.schindelin@gmx.de> Signed-off-by: Junio C Hamano <gitster@pobox.com>
* merge, pull: add '--(no-)log' command line optionSZEDER Gábor2008-04-12

* merge, pull: introduce '--(no-)stat' optionSZEDER Gábor2008-04-12
| | | | | | | | | | | | This option has the same effect as '--(no-)summary' (i.e. whether to show a diffsat at the end of the merge or not), and it is consistent with the '--stat' option of other git commands. Documentation, tests, and bash completion are updaed accordingly, and the old --summary option is marked as being deprected.

* "git pull --tags": error out with a better message.Junio C Hamano2007-12-28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When "git pull --tags" is run without any other arguments, the standard error message "You told me to fetch and merge stuff but there is nothing to merge! You might want to fix your config" is given. While the error may be technically correct, fixing the config would not help, as "git pull --tags" itself tells "git fetch" not to use the configured refspecs. This commit makes "git pull --tags" to issue a different error message to avoid confusion. This is merely an interim solution. In the longer term, it would be a better approach to change the semantics of --tags option to make "git fetch" and "git pull" to: (1) behave as if no --tags was given (so an explicit refspec on the command line overrides configured ones, or no explicit refspecs on the command line takes configured ones); but (2) no auto-following of tags is made even when using configured refspecs; and (3) fetch all tags as not-for-merge entries". Then we would not need to have this separate error message, as the ordinary merge will happen even with the --tags option. Signed-off-by: Junio C Hamano <gitster@pobox.com>
* Teach 'git pull' about --rebaseJohannes Schindelin2007-11-28
| | | | | | | | | | | | | | | | | | | | When calling 'git pull' with the '--rebase' option, it performs a fetch + rebase instead of a fetch + merge. This behavior is more desirable than fetch + pull when a topic branch is ready to be submitted and needs to be update. fetch + rebase might also be considered a better workflow with shared repositories in any case, or for contributors to a centrally managed repository, such as WINE's. As a convenience, you can set the default behavior for a branch by defining the config variable branch.<name>.rebase, which is interpreted as a bool. This setting can be overridden on the command line by --rebase and --no-rebase. Signed-off-by: Johannes Schindelin <johannes.schindelin@gmx.de> Signed-off-by: Junio C Hamano <gitster@pobox.com>

* Supplant the "while case ... break ;; esac" idiomDavid Kastrup2007-09-23
| | | | | | | | | | | | | | | | | | | | | | A lot of shell scripts contained stuff starting with while case "$#" in 0) break ;; esac and similar. I consider breaking out of the condition instead of the body od the loop ugly, and the implied "true" value of the non-matching case is not really obvious to humans at first glance. It happens not to be obvious to some BSD shells, either, but that's because they are not POSIX-compliant. In most cases, this has been replaced by a straight condition using "test". "case" has the advantage of being faster than "test" on vintage shells where "test" is not a builtin. Since none of them is likely to run the git scripts, anyway, the added readability should be worth the change. A few loops have had their termination condition expressed differently.

* git-pull: disallow implicit merging to detached HEADJeff King2007-01-15

* Allow whole-tree operations to be started from a subdirectoryJunio C Hamano2007-01-12
| | | | | | | | | | | | This updates five commands (merge, pull, rebase, revert and cherry-pick) so that they can be started from a subdirectory. This may not actually be what we want to do. These commands are inherently whole-tree operations, and an inexperienced user may mistakenly expect a "git pull" from a subdirectory would merge only the subdirectory the command started from.

* Disallow working directory commands in a bare repository.Shawn O. Pearce2007-01-10
| | | | | | | | | | | | | | | | If the user tries to run a porcelainish command which requires a working directory in a bare repository they may get unexpected results which are difficult to predict and may differ from command to command. Instead we should detect that the current repository is a bare repository and refuse to run the command there, as there is no working directory associated with it.

* fail pull/merge early in the middle of conflicted mergeJunio C Hamano2007-01-01
| | | | | | | | | | | | | | | | | | | | | | | | After a pull that results in a conflicted merge, a new user often tries another "git pull" in desperation. When the index is unmerged, merge backends correctly bail out without touching either index nor the working tree, so this does not make the wound any worse. The user will however see several lines of messsages during this process, such as "filename: needs merge", "you need to resolve your current index first", "Merging...", and "Entry ... would be overwritten by merge. Cannot merge.". They are unnecessarily alarming, and cause useful conflict messages from the first pull scroll off the top of the terminal. This changes pull and merge to run "git-ls-files -u" upfront and stop them much earlier than we currently do. Old timers may know better and would not to try pulling again before cleaning things up; this change adds extra overhead that is unnecessary for them. But this would be worth paying for to save new people from needless confusion. Signed-off-by: Junio C Hamano <junkio@cox.net>
* Allow git-merge to select the default strategy.Shawn O. Pearce2006-12-28

* Use GIT_REFLOG_ACTION environment variable instead.Shawn O. Pearce2006-12-28
| | | | | | | | | | | | | | | | | Junio rightly pointed out that the --reflog-action parameter was starting to get out of control, as most porcelain code needed to hand it to other porcelain and plumbing alike to ensure the reflog contained the top-level user action and not the lower-level actions it invoked. At Junio's suggestion we are introducing the new set_reflog_action function to all shell scripts, allowing them to declare early on what their default reflog name should be, but this setting only takes effect if the caller has not already set the GIT_REFLOG_ACTION environment variable.

| | | | | | | | | | | | | | | | We used to complain that we cannot merge anything we fetched with a local branch that does not exist yet. Just treat the case as a natural extension of fast forwarding and make the local branch'es tip point at the same commit we just fetched.

* Log ref changes made by git-merge and git-pull.Shawn Pearce2006-07-11
| | | | | | | | | | | | | | | When git-merge updates HEAD as a result of a merge record what happened during the merge into the reflog associated with HEAD (if any). The log reports who caused the update (git-merge or git-pull, by invoking git-merge), what the remote ref names were and the type of merge process used. The merge information can be useful when reviewing a reflog for a branch such as `master` where fast forward and trivial in index merges might be common as the user tracks an upstream.

* git-merge --squashJunio C Hamano2006-06-24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some people tend to do many little commits on a topic branch, recording all the trials and errors, and when the topic is reasonably cooked well, would want to record the net effect of the series as one commit on top of the mainline, removing the cruft from the history. The topic is then abandoned or forked off again from that point at the mainline. The barebone porcelainish that comes with core git tools does not officially support such operation, but you can fake it by using "git pull --no-merge" when such a topic branch is not a strict superset of the mainline, like this: git checkout mainline git pull --no-commit . that-topic-branch : fix conflicts if any rm -f .git/MERGE_HEAD git commit -a -m 'consolidated commit log message' git branch -f that-topic-branch ;# now fully merged This however does not work when the topic branch is a fast forward of the mainline, because normal "git pull" will never create a merge commit in such a case, and there is nothing special --no-commit could do to begin with. This patch introduces a new option, --squash, to support such a workflow officially in both fast-forward case and true merge case. The user-level operation would be the same in both cases: git checkout mainline git pull --squash . that-topic-branch : fix conflicts if any -- naturally, there would be : no conflict if fast forward. git commit -a -m 'consolidated commit log message' git branch -f that-topic-branch ;# now fully merged When the current branch is already up-to-date with respect to the other branch, there truly is nothing to do, so the new option does not have any effect.

* Avoid using "git-var -l" until it gets fixed.Junio C Hamano2006-02-12
| | | | | | | | | | | | | | | | | | | | | | | | | This is to be nicer to people with unusable GECOS field. "git-var -l" is currently broken in that when used by a user who does not have a usable GECOS field and has not corrected it by exporting GIT_COMMITTER_NAME environment variable it dies when it tries to output GIT_COMMITTER_IDENT (same thing for AUTHOR). "git-pull" used "git-var -l" only because it needed to get a configuration variable before "git-repo-config --get" was introduced. Use the latter tool designed exactly for this purpose. "git-sh-setup" used "git-var GIT_AUTHOR_IDENT" without actually wanting to use its value. The only purpose was to cause the command to check and barf if the repository format version recorded in the $GIT_DIR/config file is too new for us to deal with correctly. Instead, use "repo-config --get" on a random property and see if it die()s, and check if the exit status is 128 (comes from die -- missing variable is reported with exit status 1, so we can tell that case apart).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | This does two things: - It changes the hardcoded default merge strategy for two-head git-pull from resolve to recursive. - .git/config file acquires two configuration items. pull.twohead names the strategy for two-head case, and pull.octopus names the strategy for octopus merge. IOW you are paranoid, you can have the following lines in your .git/config file and keep using git-merge-resolve when pulling one remote: [pull] twohead = resolve OTOH, you can say this: [pull] twohead = resolve twohead = recursive to try quicker resolve first, and when it fails, fall back to recursive.

| | | | | | | | | | | | | | This again makes git-pull to use git-merge, so that different merge strategy can be specified from the command line. Without explicit strategy parameter, it defaults to git-merge-resolve if only one remote is pulled, and git-merge-octopus otherwise, to keep the default behaviour of the command the same as the original.
