2007-09-23git-merge: add --ff and --no-ff optionsLibravatar Lars Hjemli1-0/+20
These new options can be used to control the policy for fast-forward merges: --ff allows it (this is the default) while --no-ff will create a merge commit. Signed-off-by: Lars Hjemli <hjemli@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2007-09-23git-merge: add support for --commit and --no-squashLibravatar Lars Hjemli1-0/+22
These options can be used to override --no-commit and --squash, which is needed since --no-commit and --squash now can be specified as default merge options in $GIT_DIR/config. The change also introduces slightly different behavior for --no-commit: when specified, it explicitly overrides --squash. Earlier, 'git merge --squash --no-commit' would result in a squashed merge (i.e. no $GIT_DIR/MERGE_HEAD was created) but with this patch the command will behave as if --squash hadn't been specified.

2007-09-23git-merge: add support for branch.<name>.mergeoptionsLibravatar Lars Hjemli1-0/+54
This enables per branch configuration of merge options. Currently, the most useful options to specify per branch are --squash, --summary/--no-summary and possibly --strategy, but all options are supported. Note: Options containing whitespace will _not_ be handled correctly. Luckily, the only option which can include whitespace is --message and it doesn't make much sense to give that option a default value.

2007-09-17git-commit: Allow partial commit of file removal.Libravatar Junio C Hamano1-0/+21
When making a partial commit, git-commit uses git-ls-files with the --error-unmatch option to expand and sanity check the user supplied path patterns. When any path pattern does not match with the paths known to the index, it errors out, in order to catch a common mistake to say "git commit Makefiel cache.h" and end up with a commit that touches only cache.h (notice the misspelled "Makefile"). This detection however does not work well when the path has already been removed from the index. If you drop a path from the index and try to commit that partially, i.e. $ git rm COPYING $ git commit -m 'Remove COPYING' COPYING the command complains because git does not know anything about COPYING anymore. This introduces a new option --with-tree to git-ls-files and uses it in git-commit when we build a temporary index to write a tree object for the partial commit. When --with-tree=<tree-ish> option is specified, names from the given tree are added to the set of names the index knows about, so we can treat COPYING file in the example as known. Of course, there is no reason to use "git rm" and git-aware people have long time done: $ rm COPYING $ git commit -m 'Remove COPYING' COPYING which works just fine.

"git diff" does not record index lines for pure mode changes (i.e. no lines changed). Therefore, apply --index-info would call out a bogus error.

We used to rely on the fact that cherry-pick would trigger the code path to set limited = 1 in handle_commit(), when an uninteresting commit was encountered. However, when cherry picking between two independent branches, i.e. when there are no merge bases, and there is only linear development (which can happen when you cvsimport a fork of a project), no uninteresting commit will be encountered. So set limited = 1 when --cherry-pick was asked for. Noticed by Martin Bähr. Signed-off-by: Johannes Schindelin <johannes.schindelin@gmx.de> Signed-off-by: Junio C Hamano <gitster@pobox.com>

2007-09-14Split grep arguments in a way that does not requires to add /dev/null.Libravatar Junio C Hamano1-0/+4
In order to (almost) always show the name of the file without relying on "-H" option of GNU grep, we used to add /dev/null to the argument list unless we are doing -l or -L. This caused "/dev/null:0" to show up when -c is given in the output. It is not enough to add -c to the set of options we do not pass /dev/null for. When we have too many files, we invoke grep multiple times and we need to avoid giving a widow filename to the last invocation -- otherwise we will not see the name. This keeps two filenames when the argv[] buffer is about to overflow and we have not finished iterating over the index, so that the last round will always have at least two paths to work with (and not require /dev/null). An obvious and the only exception is when there is only 1 file that is given to the underlying grep, and in that case we avoid passing /dev/null and let the external "grep -c" report only the number of matches.

2007-09-09git-tag -s must fail if gpg cannot sign the tag.Libravatar Carlos Rica1-0/+7
Most of this patch code and message was written by Shawn O. Pearce. I made some tests to know what the problem was, and then I changed the code related with the SIGPIPE signal. If the user has misconfigured `user.signingkey` in their .git/config or just doesn't have any secret keys on their keyring and they ask for a signed tag with `git tag -s` we better make sure the resulting tag was actually signed by gpg. Prior versions of builtin git-tag allowed this failure to slip by without error as they were not checking the return value of the finish_command() so they did not notice when gpg exited with an error exit status. They also did not fail if gpg produced an empty output or if read_in_full received an error from the read system call while trying to read the pipe back from gpg. Finally, we did not actually honor any return value from the do_sign function as it returns ssize_t but was being stored into an unsigned long. This caused the compiler to optimize out the die condition, allowing git-tag to continue along and create the tag object. However, when gpg gets a wrong username, it exits before any read was done and then the writing process receives SIGPIPE and program is terminated. By ignoring this signal, anyway, the function write_or_die gets EPIPE from write_in_full and exits returning 0 to the system without a message. Here we better call to write_in_full directly so we can fail printing a message and return safely to the caller. With these issues fixed `git-tag -s` will now fail to create the tag and will report a non-zero exit status to its caller, thereby allowing automated helper scripts to detect (and recover from) failure if gpg is not working properly.

Kristian Høgsberg pointed out that the two file modifications we were doing during the 'creating initial files' step are not even used within the test suite. This was actually confusing as we do not even need these changes for the tests to pass. All that really matters here is the specific commit dates are used so that these appear in the branch's reflog, and that the dates are different so that the branch will update when asked and the reflog entry is also updated.

2007-09-05git-apply: do not read past the end of bufferLibravatar Junio C Hamano1-0/+58
When the preimage we are patching is shorter than what the patch text expects, we tried to match the buffer contents at the "original" line with the fragment in full, without checking we have enough data to match in the preimage. This caused the size of a later memmove() to wrap around and attempt to scribble almost the entire address space. Not good. The code that follows the part this patch touches tries to match the fragment with line offsets. Curiously, that code does not have the problem --- it guards against reading past the end of the preimage. Signed-off-by: Junio C Hamano <gitster@pobox.com>
2007-09-03archive: specfile support (--pretty=format: in archive files)Libravatar René Scharfe1-0/+19
Add support for a new attribute, specfile. Files marked as being specfiles are expanded by git-archive when they are written to an archive. It has no effect on worktree files. The same placeholders as those for the option --pretty=format: of git-log et al. can be used. The attribute is useful for creating auto-updating specfiles. It is limited by the underlying function format_commit_message(), though. E.g. currently there is no placeholder for git-describe like output, and expanded specfiles can't contain NUL bytes. That can be fixed in format_commit_message() later and will then benefit users of git-log, too.

2007-08-31git-tag: Fix -l option to use better shell style globs.Libravatar Carlos Rica1-11/+9
This patch removes certain behaviour of "git tag -l foo", currently listing every tag name having "foo" as a substring. The same thing now could be achieved doing "git tag -l '*foo*'". This feature was added recently when git-tag.sh got the -n option for showing tag annotations, because that commit also replaced the old "grep pattern" behaviour with a more preferable "shell pattern" behaviour (although slightly modified as you can see). Thus, the following builtin-tag.c implemented it in order to ensure that tests were passing unchanged with both programs. Since common "shell patterns" match names with a given substring _only_ when * is inserted before and after (as in "*substring*"), and the "plain" behaviour cannot be achieved easily with the current implementation, this is mostly the right thing to do, in order to make it more flexible and consistent. Tests for "git tag" were also changed to reflect this. Signed-off-by: Carlos Rica <jasampler@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2007-08-31git-svn: fix dcommit clobbering upstream when committing multiple changesLibravatar Eric Wong1-0/+30
Although dcommit could detect if the first commit in the series would conflict with the HEAD revision in SVN, it could not detect conflicts in further commits it made. Now we rebase each uncommitted change after each revision is committed to SVN to ensure that we are up-to-date. git-rebase will bail out on conflict errors if our next change cannot be applied and committed to SVN cleanly, preventing accidental clobbering of changes on the SVN-side. --no-rebase users will have trouble with this, and are thus warned if they are committing more than one commit. Fixing this for (hopefully uncommon) --no-rebase users would be more complex and will probably happen at a later date. Thanks to David Watson for finding this and the original test.

2007-08-27git-merge: do up-to-date check also for all strategiesLibravatar Junio C Hamano1-0/+77
This clarifies the logic to omit fast-forward check and omit trivial merge before running the specified strategy. The "index_merge" variable started out as a flag to say "do not do anything clever", but when recursive was changed to skip the trivial merge, the semantics were changed and the variable alone does not make sense anymore. This splits the variable into two, allow_fast_forward (which is almost always true, and avoids making a merge commit when the other commit is a descendant of our branch, but is set to false for ours and subtree) and allow_trivial_merge (which is false for ours, recursive and subtree). Unlike the earlier implementation, the "ours" strategy allows an up-to-date condition. When we are up-to-date, the result will be our commit, and by definition, we will have our tree as the result.

2007-08-27Fix initialization of a bare repositoryLibravatar Junio C Hamano1-0/+116
Here is my attempt to fix this with a minimally intrusive patch. * As "git --bare init" cannot tell if it was called with --bare or just "GIT_DIR=. git init", I added an explicit assignment of is_bare_repository_cfg on the codepath for "git --bare". * GIT_WORK_TREE alone without GIT_DIR does not make any sense, nor GIT_WORK_TREE with an explicit "git --bare". Catch that mistake. It might make sense to move this check to "git.c" side as well, but I tried to shoot for the minimum change for now. * Some scripts, especially from the olden days, rely on traditional GIT_DIR behaviour in "git init". Namely, these are some notable patterns: (create a bare repository) - mkdir some.git && cd some.git && GIT_DIR=. git init - mkdir some.git && cd some.git && git --bare init (create a non-bare repository) - mkdir .git && GIT_DIR=.git git init - mkdir .git && GIT_DIR=`pwd`/.git git init This comes with a new test script and also passes the existing test suite, but there may be cases that are still broken with the current tip of master and this patch does not yet fix.

After git-write-tree finishes computing the tree, it updates the index so that later operations can take advantage of fully populated cache tree. However, anybody writing the index file has to mark the entries that are racily clean. For each entry whose cached lstat(3) data in the index exactly matches what is obtained from the filesystem, if the timestamp on the index file was the same or older than the modification timestamp of the file, the blob contents and the work tree file, after convert_to_git(), need to be compared, and if they are different, its index entry needs to be marked not to match the lstat(3) data from the filesystem. In order for this to work, convert_to_git() needs to work correctly, which in turn means you need to read the config file to get the settings of core.crlf and friends.

However there was not a way to know when fast-import had finished executing the checkpoint and it was safe to read those refs.

2007-08-19Make trailing LF optional for all fast-import commandsLibravatar Shawn O. Pearce1-0/+46
For the same reasons as the prior change we want to allow frontends to omit the trailing LF that usually delimits commands. In some cases these just make the input stream more verbose looking than it needs to be, and its just simpler for the frontend developer to get started if our parser is slightly more lenient about where an LF is required and where it isn't. To make this optional LF feature work we now have to buffer up to one line of input in command_buf. This buffering can happen if we look at the current input command but don't recognize it at this point in the code. In such a case we need to "unget" the entire line, but we cannot depend upon the stdio library to let us do ungetc() for that many characters at once. Signed-off-by: Shawn O.

We can easily make the LF optional by peeking at the next byte available from the stream and pushing it back into the buffer if its not LF. Signed-off-by: Shawn O. Pearce <spearce@spearce.org>
2007-08-19Teach fast-import to ignore lines starting with '#'Libravatar Shawn O. Pearce1-0/+40
Several frontend developers have asked that some form of stream comments be permitted within a fast-import data stream. This way they can include information from their own frontend program about where specific data was taken from in the source system, or about a decision that their frontend may have made while creating the fast-import data stream. This change introduces comments in the Bourne-shell/Tcl/Perl style. Lines starting with '#' are ignored, up to and including the LF. Unlike the above mentioned three languages however we do not look for and ignore leading whitespace. This just simplifies the definition of the comment format and the code that parses them. To make comments work we had to stop using read_next_command() within cmd_data() and directly invoke read_line() during the inline variant of the function. This is necessary to retain any lines of the input data that might otherwise look like a comment to fast-import. Signed-off-by: Shawn O. Pearce <spearce@spearce.org>
2007-08-19Actually allow TAG_FIXUP branches in fast-importLibravatar Shawn O. Pearce1-0/+47
Michael Haggerty <mhagger@alum.mit.edu> noticed while debugging a Git backend for cvs2svn that fast-import was barfing when he tried to use "TAG_FIXUP" as a branch name for temporary work needed to cleanup the tree prior to creating an annotated tag object. The reason we were rejecting the branch name was check_ref_format() returns -2 when there are less than 2 '/' characters in the input name. TAG_FIXUP has 0 '/' characters, but is technically just as valid of a ref as HEAD and MERGE_HEAD, so we really should permit it (and any other similar looking name) during import. New test cases have been added to make sure we still detect very wrong branch names (e.g. containing [ or starting with .) and yet still permit reasonable names (e.g. TAG_FIXUP).

2007-08-15git-apply: apply submodule changesLibravatar Sven Verdoolaege1-0/+17
Apply "Subproject commit HEX" changes produced by git-diff. As usual in the current git, only the superproject itself is actually modified (possibly creating empty directories for new submodules). Any checked-out submodule is left untouched and is not required to be up-to-date. With clean-ups from Junio C Hamano.
