2008-02-22Avoid unnecessary "if-before-free" tests.Libravatar Jim Meyering1-6/+3
This change removes all obvious useless if-before-free tests. E.g., it replaces code like this: if (some_expression) free (some_expression); with the now-equivalent: free (some_expression); It is equivalent not just because POSIX has required free(NULL) to work for a long time, but simply because it has worked for so long that no reasonable porting target fails the test. Here's some evidence from nearly 1.5 years ago: http://www.winehq.org/pipermail/wine-patches/2006-October/031544.html FYI, the change below was prepared by running the following: git ls-files -z | xargs -0 \ perl -0x3b -pi -e \ 's/\bif\s*\(\s*(\S+?)(?:\s*!=\s*NULL)?\s*\)\s+(free\s*\(\s*\1\s*\))/$2/s' Note however, that it doesn't handle brace-enclosed blocks like "if (x) { free (x); }". But that's ok, since there were none like that in git sources. Beware: if you do use the above snippet, note that it can produce syntactically invalid C code. That happens when the affected "if"-statement has a matching "else". E.g., it would transform this if (x) free (x); else foo (); into this: free (x); else foo (); There were none of those here, either. If you're interested in automating detection of the useless tests, you might like the useless-if-before-free script in gnulib: [it *does* detect brace-enclosed free statements, and has a --name=S option to make it detect free-like functions with different names] http://git.sv.gnu.org/gitweb/?p=gnulib.git;a=blob;f=build-aux/useless-if-before-free Addendum: Remove one more (in imap-send.c), spotted by Jean-Luc Herren <jlh@gmx.ch>.

2008-02-19branch: optionally setup branch.*.merge from upstream local branchesLibravatar Jay Soffian1-8/+5
"git branch" and "git checkout -b" now honor --track option even when the upstream branch is local. Previously --track was silently ignored when forking from a local branch. Also the command did not error out when --track was explicitly asked for but the forked point specified was not an existing branch (i.e. when there is no way to set up the tracking configuration), but now it correctly does. The configuration setting branch.autosetupmerge can now be set to "always", which is equivalent to using --track from the command line. Setting branch.autosetupmerge to "true" will retain the former behavior of only setting up branch.*.merge for remote upstream branches. Includes test cases for the new functionality.

2007-12-05git config --get-colorboolLibravatar Junio C Hamano1-1/+1
This adds an option to help scripts find out color settings from the configuration file. git config --get-colorbool color.diff inspects color.diff variable, and exits with status 0 (i.e. success) if color is to be used. It exits with status 1 otherwise. If a script wants "true"/"false" answer to the standard output of the command, it can pass an additional boolean parameter to its command line, telling if its standard output is a terminal, like this: git config --get-colorbool color.diff true When called like this, the command outputs "true" to its standard output if color is to be used (i.e. "color.diff" says "always", "auto", or "true"), and "false" otherwise.

2007-11-22git-branch --contains=commitLibravatar Junio C Hamano1-3/+54
This teaches git-branch to limit its listing to branches that are descendants to the named commit. When you are using many topic branches, you often would want to see which branch already includes a commit, so that you know which can and cannot be rewound without disrupting other people. One thing that sometimes happens to me is: * Somebody sends a patch that is a good maint material. I apply it to 'maint': $ git checkout maint $ git am -3 -s obvious-fix.patch * Then somebody else sends another patch that is possibly a good maint material, but I'd want to cook it in 'next' to be extra sure. I fork a topic from 'maint' and apply the patch: $ git checkout -b xx/maint-fix-foo $ git am -3 -s ,xx-maint-fix-foo.patch * A minor typo is found in the "obvious-fix.patch". The above happens without pushing the results out, so I can freely recover from it by amending 'maint', as long as I do not forget to rebase the topics that were forked previously. With this patch, I can do this to find out which topic branches already contain the faulty commit: $ git branch --contains=maint^ xx/maint-fix-foo so I can rebase the xx/maint-fix-foo branch before merging it to 'next'.

The term "ancestor" is a bit more intuitive (and more consistent with the documentation) than the term "strict subset". Also, remove superfluous "ref", capitalize, and add some carriage returns, changing: error: remote 'refs/heads/master' is not a strict subset of local ref 'refs/heads/master'. maybe you are not up-to-date and need to pull first? error: failed to push to 'ssh://linux-nfs.org/~bfields/exports/git.git' to: error: remote 'refs/heads/master' is not an ancestor of local 'refs/heads/master'.

When the body of the commit log message contains a non-ASCII character, format-patch correctly emitted the encoding header to mark the resulting message as such. However, if the original message was fully ASCII, the command line switch "-s" was given to add a new sign-off, and the signer's name was not ASCII only, the resulting message would have contained non-ASCII character but was not marked as such.

2007-09-10Rework pretty_print_commit to use strbufs instead of custom buffers.Libravatar Pierre Habouzit1-8/+7
Also remove the "len" parameter, as: (1) it was used as a max boundary, and every caller used ~0u (2) we check for final NUL no matter what, so it doesn't help for speed. As a result most of the pp_* function takes 3 arguments less, and we need a lot less local variables, this makes the code way more readable, and easier to extend if needed.

2007-07-11branch --track: code cleanup and saner handling of local branchesLibravatar Johannes Schindelin1-115/+55
This patch cleans up some complicated code, and replaces it with a cleaner version, using code from remote.[ch], which got extended a little in the process. This also enables us to fix two cases: The earlier "fix" to setup tracking only when the original ref started with "refs/remotes" is wrong. You are absolutely allowed to use a separate layout for your tracking branches. The correct fix, of course, is to set up tracking information only when there is a matching remote.<nick>.fetch line containing a colon. Another corner case was not handled properly. If two remotes write to the original ref, just warn the user and do not set up tracking.

2007-07-08branch.autosetupmerge: allow boolean values, or "all"Libravatar Johannes Schindelin1-6/+12
Junio noticed that switching on autosetupmerge unilaterally started cluttering the config for local branches. That is not the original intention of branch.autosetupmerge, which was meant purely for convenience when branching off of remote branches, but that semantics got lost somewhere. If you still want that "new" behavior, you can switch branch.autosetupmerge to the value "all". Otherwise, it is interpreted as a boolean, which triggers setting up defaults _only_ when branching off of a remote branch, i.e. the originally intended behavior.

2007-07-06git-branch: default to --trackLibravatar Johannes Schindelin1-1/+1
"git branch --track" will setup config variables when branching from a remote branch, so that if you say "git pull" while being on that branch, it automatically fetches the correct remote, and merges the correct branch. Often people complain that this is not the default for "git branch". Make it so. Signed-off-by: Johannes Schindelin <Johannes.Schindelin@gmx.de> Signed-off-by: Junio C Hamano <gitster@pobox.com>

2007-06-13Lift 16kB limit of log message outputLibravatar Junio C Hamano1-6/+11
Traditionally we had 16kB limit when formatting log messages for output, because it was easier to arrange for the caller to have a reasonably big buffer and pass it down without ever worrying about reallocating. This changes the calling convention of pretty_print_commit() to lift this limit. Instead of the buffer and remaining length, it now takes a pointer to the pointer that points at the allocated buffer, and another pointer to the location that stores the allocated length, and reallocates the buffer as necessary. To support the user format, the error return of interpolate() needed to be changed. It used to return a bool telling "Ok the result fits", or "Sorry, I had to truncate it". Now it returns 0 on success, and returns the size of the buffer it wants in order to fit the whole result. Signed-off-by: Junio C Hamano <gitster@pobox.com>

2007-03-16git-fetch, git-branch: Support local --track via a special remote '.'Libravatar Paolo Bonzini1-14/+25
This patch adds support for a dummy remote '.' to avoid having to declare a fake remote like [remote "local"] url = . fetch = refs/heads/*:refs/heads/* Such a builtin remote simplifies the operation of "git-fetch", which will populate FETCH_HEAD but will not pretend that two repositories are in use, will not create a thin pack, and will not perform any useless remapping of names. The speed improvement is around 20%, and it should improve more if "git-fetch" is converted to a builtin. To this end, git-parse-remote is grown with a new kind of remote, 'builtin'. In git-fetch.sh, we treat the builtin remote specially in that it needs no pack/store operations. In fact, doing git-fetch on a builtin remote will simply populate FETCH_HEAD appropriately. The patch also improves of the --track/--no-track support, extending it so that branch.<name>.remote items referring '.' can be created. Finally, it fixes a typo in git-checkout.sh.

2007-03-10git-branch, git-checkout: autosetup for remote branch trackingLibravatar Paolo Bonzini1-8/+132
In order to track and build on top of a branch 'topic' you track from your upstream repository, you often would end up doing this sequence: git checkout -b mytopic origin/topic git config --add branch.mytopic.remote origin git config --add branch.mytopic.merge refs/heads/topic This would first fork your own 'mytopic' branch from the 'topic' branch you track from the 'origin' repository; then it would set up two configuration variables so that 'git pull' without parameters does the right thing while you are on your own 'mytopic' branch. This commit adds a --track option to git-branch, so that "git branch --track mytopic origin/topic" performs the latter two actions when creating your 'mytopic' branch. If the configuration variable branch.autosetupmerge is set to true, you do not have to pass the --track option explicitly; further patches in this series allow setting the variable with a "git remote add" option. The configuration variable is off by default, and there is a --no-track option to countermand it even if the variable is set.

2007-03-07General const correctness fixesLibravatar Shawn O. Pearce1-1/+2
We shouldn't attempt to assign constant strings into char*, as the string is not writable at runtime. Likewise we should always be treating unsigned values as unsigned values, not as signed values. Most of these are very straightforward. The only exception is the (unnecessary) xstrdup/free in builtin-branch.c for the detached head case. Since this is a user-level interactive type program and that particular code path is executed no more than once, I feel that the extra xstrdup call is well worth the easy elimination of this warning.

Even when -l is not given from the command line, the repository may have the configuration variable core.logallrefupdates set, or an old-timer might have done ": >.git/logs/refs/heads/new" before running "git branch new". In these cases, the code gave an uninitialized msg[] from the stack to be written out as the reflog message. This also passes a different message when '-f' option is used. Saying "git branch -f branch some-commit" is a moral equilvalent of doing "git-reset some-commit" while on the branch. Signed-off-by: Junio C Hamano <junkio@cox.net>

2007-01-08Detached HEAD (experimental)Libravatar Junio C Hamano1-7/+17
This allows "git checkout v1.4.3" to dissociate the HEAD of repository from any branch. After this point, "git branch" starts reporting that you are not on any branch. You can go back to an existing branch by saying "git checkout master", for example. This is still experimental. While I think it makes sense to allow commits on top of detached HEAD, it is rather dangerous unless you are careful in the current form. Next "git checkout master" will obviously lose what you have done, so we might want to require "git checkout -f" out of a detached HEAD if we find that the HEAD commit is not an ancestor of any other branches. There is no such safety valve implemented right now. On the other hand, the reason the user did not start the ad-hoc work on a new branch with "git checkout -b" was probably because the work was of a throw-away nature, so the convenience of not having that safety valve might be even better. The user, after accumulating some commits on top of a detached HEAD, can always create a new branch with "git checkout -b" not to lose useful work done while the HEAD was detached. We'll see.
