2007-10-16Merge branch 'master' into db/fetch-packShawn O. Pearce
There's a number of tricky conflicts between master and this topic right now due to the rewrite of builtin-push. Junio must have handled these via rerere; I'd rather not deal with them again so I'm pre-merging master into the topic. Besides this topic somehow started to depend on the strbuf series that was in next, but is now in master. It no longer compiles on its own without the strbuf API. * master: (184 commits) Whip post 1.5.3.4 maintenance series into shape. Minor usage update in setgitperms.perl manual: use 'URL' instead of 'url'. manual: add some markup. manual: Fix example finding commits referencing given content. Fix wording in push definition. Fix some typos, punctuation, missing words, minor markup. manual: Fix or remove em dashes. Add a --dry-run option to git-push. Add a --dry-run option to git-send-pack.

2007-07-30log_ref_write() -- do not chomp reflog message at the first LFJunio C Hamano
A reflog file is organized as one-line-per-entry records, and we enforced the file format integrity by chomping the given message at the first LF. This changes it to convert them to SP, which is more in line with the --pretty=oneline format. Signed-off-by: Junio C Hamano <gitster@pobox.com>

2007-05-26Move refspec pattern matching to match_refs().Daniel Barkalow
This means that send-pack and http-push will support pattern refspecs, so builtin-push.c doesn't have to expand them, and also git push can just turn --tags into "refs/tags/*", further simplifying builtin-push.c check_ref_format() gets a third "conditionally okay" result for something that's valid as a pattern but not as a particular ref.

2007-04-18refs.c: add a function to sort a ref list, rather then sorting on addJulian Phillips
Rather than sorting the refs list while building it, sort in one go after it is built using a merge sort. This has a large performance boost with large numbers of refs. It shouldn't happen that we read duplicate entries into the same list, but just in case sort_ref_list drops them if the SHA1s are the same, or dies, as we have no way of knowing which one is the correct one.

This new function resolves a ref in *another* git repository. It's named for its intended use: to look up the git link to a subproject.

2007-04-06Make builtin-branch.c handle the git config fileLars Hjemli
This moves the knowledge about .git/config usage out of refs.c and into builtin-branch.c instead, which allows git-branch to update HEAD to point at the moved branch before attempting to update the config file. It also allows git-branch to exit with an error code if updating the config file should fail. Signed-off-by: Lars Hjemli <hjemli@gmail.com> Signed-off-by: Junio C Hamano <junkio@cox.net>

The HEAD reflog is updated as well as the reflog for the branch pointed to by HEAD whenever it is referenced with "HEAD". There are some cases where a specific branch may be modified directly.

2007-03-07Cast 64 bit off_t to 32 bit size_tShawn O. Pearce
Some systems have sizeof(off_t) == 8 while sizeof(size_t) == 4. This implies that we are able to access and work on files whose maximum length is around 2^63-1 bytes, but we can only malloc or mmap somewhat less than 2^32-1 bytes of memory. On such a system an implicit conversion of off_t to size_t can cause the size_t to wrap, resulting in unexpected and exciting behavior. Right now we are working around all gcc warnings generated by the -Wshorten-64-to-32 option by passing the off_t through xsize_t(). In the future we should make xsize_t on such problematic platforms detect the wrapping and die if such a file is accessed. Signed-off-by: Shawn O.

2007-02-21Mechanical conversion to use prefixcmp()Junio C Hamano
This mechanically converts strncmp() to use prefixcmp(), but only when the parameters match specific patterns, so that they can be verified easily. Leftover from this will be fixed in a separate step, including idiotic conversions like if (!strncmp("foo", arg, 3)) => if (!(-prefixcmp(arg, "foo"))) This was done by using this script in px.perl #!/usr/bin/perl -i.bak -p if (/strncmp\(([^,]+), "([^\\"]*)", (\d+)\)/ && (length($2) == $3)) { s|strncmp\(([^,]+), "([^\\"]*)", (\d+)\)|prefixcmp($1, "$2")|; } if (/strncmp\("([^\\"]*)", ([^,]+), (\d+)\)/ && (length($1) == $3)) { s|strncmp\("([^\\"]*)", ([^,]+), (\d+)\)|(-prefixcmp($2, "$1"))|; } and running: $ git grep -l strncmp -- '*.c' | xargs perl px.perl Signed-off-by: Junio C Hamano <junkio@cox.net>

2007-02-07for-each-reflog: fix case for empty log directoryJunio C Hamano
When we remove the last reflog in a directory, opendir() would succeed and we would iterate over its dirents, expecting retval to be initialized to zero and setting it to non-zero only upon seeing an error. If the directory is empty, oops!, we do not have anybody that touches retval. The problem is because we initialize retval to errno even on success from opendir(), which would leave the errno unmolested. Signed-off-by: Junio C Hamano <junkio@cox.net>

2007-01-29lock_any_ref_for_update(): do not accept malformatted refs.Junio C Hamano
We used to use lock_any_ref_for_update() because the command needs to also update HEAD (which is not under refs/, so lock_ref_sha1() cannot be used). The function however did not check for refs with illegal characters in them. Use check_ref_format() to catch malformed refs. For this check, we specifically do not want to say having less than two levels in the name is illegal to allow HEAD (and perhaps other special refs in the future).

2007-01-28create_symref(): do not assume pathname from git_path() persists long enoughJunio C Hamano
Being lazy to rely on the cycling N buffers mkpath() and friends return is nice in general, but it makes it too easy to introduce new bugs that are "mysterious". Introduction of read_ref() in create_symref() after calling git_path() to get the git_HEAD value (i.e. the path to create a new symref at) consumed more than the available buffers and broke a later call to mkpath() that derives lockpath from it.

2007-01-26Allow non-developer to clone, checkout and fetch more easily.Junio C Hamano
The code that uses committer_info() in reflog can barf and die whenever it is asked to update a ref. And I do not think calling ignore_missing_committer_name() upfront like recent receive-pack did in the aplication is a reasonable workaround. What the patch does. - git_committer_info() takes one parameter. It used to be "if this is true, then die() if the name is not available due to bad GECOS, otherwise issue a warning once but leave the name empty". The reason was because we wanted to prevent bad commits from being made by git-commit-tree (and its callers). The value 0 is only used by "git var -l". Now it takes -1, 0 or 1. When set to -1, it does not complain but uses the pw->pw_name when name is not available. Existing 0 and 1 values mean the same thing as they used to mean before. 0 means issue warnings and leave it empty, 1 means barf and die. - ignore_missing_committer_name() and its existing caller (receive-pack, to set the reflog) have been removed. - git-format-patch, to come up with the phoney message ID when asked to thread, now passes -1 to git_committer_info(). This codepath uses only the e-mail part, ignoring the name. It used to barf and die. The other call in the same program when asked to add signed-off-by line based on committer identity still passes 1 to make sure it barfs instead of adding a bogus s-o-b line. - log_ref_write in refs.c, to come up with the name to record who initiated the ref update in the reflog, passes -1. It used to barf and die. The last change means that git-update-ref, git-branch, and commit walker backends can now be used in a repository with reflog by somebody who does not have the user identity required to make a commit. They all used to barf and die. I've run tests and all of them seem to pass, and also tried "git clone" as a user whose GECOS is empty -- git clone works again now (it was broken when reflog was enabled by default). But this definitely needs extra sets of eyeballs. Signed-off-by: Junio C Hamano <junkio@cox.net>

This changes the output so the list at the top shows the reflog message, along with their relative timestamps.

I did not like the log message, so I amended again at @{5}. Then I cherry-picked @{9}~2 to create @{3} (the log message shows that it needs to learn to set GIT_REFLOG_ACTION -- it uses "git-commit" and the log entry is attributed for it).

It used to ignore the return value of the helper function; now, it expects it to return 0, and stops iteration upon non-zero return values; this value is then passed on as the return value of for_each_reflog_ent().
