2007-07-02Make '!' aliases more usefulLibravatar Johannes Schindelin1-0/+15
When an alias starts with an exclamation mark, the rest is interpreted as a shell command. However, all arguments passed to git used to be ignored. Now you can have an alias like $ git config alias.e '!echo' and $ git e Hello World does what you expect it to do.

2007-06-30git: Try a bit harder not to lose errno in stdioLibravatar Linus Torvalds1-4/+5
This switches the checks around upon the exit codepath of the git wrapper, so that we may recover at least non-transient errors. It's still not perfect. As I've been harping on, stdio simply isn't very good for error reporting. For example, if an IO error happened, you'd want to see EIO, wouldn't you? And yes, that's what the kernel would return. However, with buffered stdio (and flushing outside of our control), what would likely happen is that some intermediate error return _does_ return EIO, but then the kernel might decide to re-mount the filesystem read-only due to the error, and the actual *report* for us might be "write failure on standard output: read-only filesystem" which lost the EIO.

2007-06-24Check for IO errors after running a commandLibravatar Linus Torvalds1-1/+20
This is trying to implement the strict IO error checks that Jim Meyering suggested, but explicitly limits it to just regular files. If a pipe gets closed on us, we shouldn't complain about it. If the subcommand already returned an error, that takes precedence (and we assume that the subcommand already printed out any relevant messages relating to it) Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2007-06-24Clean up internal command handlingLibravatar Linus Torvalds1-22/+30
This should change no code at all, it just moves the definition of "struct cmd_struct" out, and then splits out the running of the right command into the "run_command()" function. It also removes the long-unused 'envp' pointer passing. This is just preparation for adding some more error checking.

2007-06-12make git barf when an alias changes environment variablesLibravatar Matthias Lederhofer1-4/+18
Aliases changing environment variables (GIT_DIR or GIT_WORK_TREE) can cause problems: git has to use GIT_DIR to read the aliases from the config. After running handle_options for the alias the options of the alias may have changed environment variables. Depending on the implementation of setenv the memory location obtained through getenv earlier may contain the old value or the new value (or even be used for something else?). To avoid these problems git errors out if an alias uses any option which changes environment variables.

2007-06-06Use new semantics of is_bare/inside_git_dir/inside_work_treeLibravatar Matthias Lederhofer1-10/+10
Up to now to check for a working tree this was used: !is_bare && !inside_git_dir (the check for bare is redundant because is_inside_git_dir returned already 1 for bare repositories). Now the check is: inside_work_tree && !inside_git_dir Signed-off-by: Matthias Lederhofer <matled@gmx.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2007-06-06introduce GIT_WORK_TREE to specify the work treeLibravatar Matthias Lederhofer1-1/+11
setup_gdg is used as abbreviation for setup_git_directory_gently. The work tree can be specified using the environment variable GIT_WORK_TREE and the config option core.worktree (the environment variable has precendence over the config option). Additionally there is a command line option --work-tree which sets the environment variable. setup_gdg does the following now: GIT_DIR unspecified repository in .git directory parent directory of the .git directory is used as work tree, GIT_WORK_TREE is ignored GIT_DIR unspecified repository in cwd GIT_DIR is set to cwd see the cases with GIT_DIR specified what happens next and also see the note below GIT_DIR specified GIT_WORK_TREE/core.worktree unspecified cwd is used as work tree GIT_DIR specified GIT_WORK_TREE/core.worktree specified the specified work tree is used Note on the case where GIT_DIR is unspecified and repository is in cwd: GIT_WORK_TREE is used but is_inside_git_dir is always true. I did it this way because setup_gdg might be called multiple times (e.g. when doing alias expansion) and in successive calls setup_gdg should do the same thing every time. Meaning of is_bare/is_inside_work_tree/is_inside_git_dir: (1) is_bare_repository A repository is bare if core.bare is true or core.bare is unspecified and the name suggests it is bare (directory not named .git). The bare option disables a few protective checks which are useful with a working tree. Currently this changes if a repository is bare: updates of HEAD are allowed git gc packs the refs the reflog is disabled by default (2) is_inside_work_tree True if the cwd is inside the associated working tree (if there is one), false otherwise. (3) is_inside_git_dir True if the cwd is inside the git directory, false otherwise. Before this patch is_inside_git_dir was always true for bare repositories. When setup_gdg finds a repository git_config(git_default_config) is always called. This ensure that is_bare_repository makes use of core.bare and does not guess even though core.bare is specified. inside_work_tree and inside_git_dir are set if setup_gdg finds a repository. The is_inside_work_tree and is_inside_git_dir functions will die if they are called before a successful call to setup_gdg.

2007-04-14Add basic infrastructure to assign attributes to pathsLibravatar Junio C Hamano1-0/+1
This adds the basic infrastructure to assign attributes to paths, in a way similar to what the exclusion mechanism does based on $GIT_DIR/info/exclude and .gitignore files. An attribute is just a simple string that does not contain any whitespace. They can be specified in $GIT_DIR/info/attributes file, and .gitattributes file in each directory. Each line in these files defines a pattern matching rule. Similar to the exclusion mechanism, a later match overrides an earlier match in the same file, and entries from .gitattributes file in the same directory takes precedence over the ones from parent directories. Lines in $GIT_DIR/info/attributes file are used as the lowest precedence default rules. A line is either a comment (an empty line, or a line that begins with a '#'), or a rule, which is a whitespace separated list of tokens. The first token on the line is a shell glob pattern. The rest are names of attributes, each of which can optionally be prefixed with '!'. Such a line means "if a path matches this glob, this attribute is set (or unset -- if the attribute name is prefixed with '!'). For glob matching, the same "if the pattern does not have a slash in it, the basename of the path is matched with fnmatch(3) against the pattern, otherwise, the path is matched with the pattern with FNM_PATHNAME" rule as the exclusion mechanism is used. This does not define what an attribute means. Tying an attribute to various effects it has on git operation for paths that have it will be specified separately.

2007-02-22Add git-bundle: move objects and references by archiveLibravatar Johannes Schindelin1-0/+1
Some workflows require use of repositories on machines that cannot be connected, preventing use of git-fetch / git-push to transport objects and references between the repositories. git-bundle provides an alternate transport mechanism, effectively allowing git-fetch and git-pull to operate using sneakernet transport. `git-bundle create` allows the user to create a bundle containing one or more branches or tags, but with specified basis assumed to exist on the target repository. At the receiving end, git-bundle acts like git-fetch-pack, allowing the user to invoke git-fetch or git-pull using the bundle file as the URL. git-fetch and git-ls-remote determine they have a bundle URL by checking that the URL points to a file, but are otherwise unchanged in operation with bundles. The original patch was done by Mark Levedahl <mdl123@verizon.net>. It was updated to make git-bundle a builtin, and get rid of the tar format: now, the first line is supposed to say "# v2 git bundle", the next lines either contain a prerequisite ("-" followed by the hash of the needed commit), or a ref (the hash of a commit, followed by the name of the ref), and finally the pack. As a result, the bundle argument can be "-" now. Signed-off-by: Johannes Schindelin <johannes.schindelin@gmx.de> Signed-off-by: Junio C Hamano <junkio@cox.net>
2007-02-22Teach git-diff-files the new option `--no-index`Libravatar Johannes Schindelin1-2/+2
With this flag and given two paths, git-diff-files behaves as a GNU diff lookalike (plus the git goodies like --check, colour, etc.). This flag is also available in git-diff. It also works outside of a git repository. In addition, if git-diff{,-files} is called without revision or stage parameter, and with exactly two paths at least one of which is not tracked, the default is --no-index. So, you can now say git diff /etc/inittab /etc/fstab and it actually works! This also unifies the duplicated argument parsing between cmd_diff_files() and builtin_diff_files().

2007-02-20Mechanical conversion to use prefixcmp()Libravatar Junio C Hamano1-5/+5
