2007-12-09Re-fix "builtin-commit: fix --signoff"Libravatar Junio C Hamano1-1/+1
An earlier fix to the said commit was incomplete; it mixed up the meaning of the flag parameter passed to the internal fmt_ident() function, so this corrects it. git_author_info() and git_committer_info() can be told to issue a warning when no usable user information is found, and optionally can be told to error out. Operations that actually use the information to record a new commit or a tag will still error out, but the caller to leave reflog record will just silently use bogus user information. Not warning on misconfigured user information while writing a reflog entry is somewhat debatable, but it is probably nicer to the users to silently let it pass, because the only information you are losing is who checked out the branch. * git_author_info() and git_committer_info() used to take 1 (positive int) to error out with a warning on misconfiguration; this is now signalled with a symbolic constant IDENT_ERROR_ON_NO_NAME. * These functions used to take -1 (negative int) to warn but continue; this is now signalled with a symbolic constant IDENT_WARN_ON_NO_NAME. * fmt_ident() function implements the above error reporting behaviour common to git_author_info() and git_committer_info(). A symbolic constant IDENT_NO_DATE can be or'ed in to the flag parameter to make it return only the "Name <email@address.xz>". * fmt_name() is a thin wrapper around fmt_ident() that always passes IDENT_ERROR_ON_NO_NAME and IDENT_NO_DATE.

2007-11-18refactor fetch's ref matching to use refname_match()Libravatar Steffen Prohaska1-0/+7
The old rules used by fetch were coded as a series of ifs. The old rules are: 1) match full refname if it starts with "refs/" or matches "HEAD" 2) verify that full refname starts with "refs/" 3) match abbreviated name in "refs/" if it starts with "heads/", "tags/", or "remotes/". 4) match abbreviated name in "refs/heads/" This is replaced by the new rules a) match full refname b) match abbreviated name prefixed with "refs/" c) match abbreviated name prefixed with "refs/heads/" The details of the new rules are different from the old rules. We no longer verify that the full refname starts with "refs/". The new rule (a) matches any full string. The old rules (1) and (2) were stricter. Now, the caller is responsible for using sensible full refnames. This should be the case for the current code. The new rule (b) is less strict than old rule (3). The new rule accepts abbreviated names that start with a non-standard prefix below "refs/". Despite this modifications the new rules should handle all cases as expected. Two tests are added to verify that fetch does not resolve short tags or HEAD in remotes. We may even think about loosening the rules a bit more and unify them with the rev-parse rules. This would be done by replacing ref_ref_fetch_rules with ref_ref_parse_rules. Note, the two new test would break.

2007-11-18add refname_match()Libravatar Steffen Prohaska1-0/+24
We use at least two rulesets for matching abbreviated refnames with full refnames (starting with 'refs/'). git-rev-parse and git-fetch use slightly different rules. This commit introduces a new function refname_match (const char *abbrev_name, const char *full_name, const char **rules). abbrev_name is expanded using the rules and matched against full_name. If a match is found the function returns true. rules is a NULL-terminate list of format patterns with "%.*s", for example: const char *ref_rev_parse_rules[] = { "%.*s", "refs/%.*s", "refs/tags/%.*s", "refs/heads/%.*s", "refs/remotes/%.*s", "refs/remotes/%.*s/HEAD", NULL }; Asterisks are included in the format strings because this is the form required in sha1_name.c. Sharing the list with the functions there is a good idea to avoid duplicating the rules. Hopefully this facilitates unified matching rules in the future. This commit makes the rules used by rev-parse for resolving refs to sha1s available for string comparison. Before this change, the rules were buried in get_sha1*() and dwim_ref(). A follow-up commit will refactor the rules used by fetch. refname_match() will be used for matching refspecs in git-send-pack. Thanks to Daniel Barkalow <barkalow@iabervon.org> for pointing out that ref_matches_abbrev in remote.c solves a similar problem and care should be taken to avoid confusion.

2007-04-18refs.c: add a function to sort a ref list, rather then sorting on addLibravatar Julian Phillips1-21/+89
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.

2007-03-07Cast 64 bit off_t to 32 bit size_tLibravatar Shawn O. Pearce1-3/+5
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.

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.

2007-01-25Allow non-developer to clone, checkout and fetch more easily.Libravatar Junio C Hamano1-1/+1
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>

I first saved them with "format-patch -4", and then did a reset at @{8}. At @{7}, I applied one of them with "am", and then used "git-apply" on the other one, and amended the commit at @{6} (so @{6} and @{7} has the same parent). 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). Another cherry-pick built @{2} out of @{9}, but what I wanted to do was to squash these two into one, so I did a "reset HEAD^" at @{1} and then made the final commit by amending what was at the top.

2007-01-19Extend read_ref_at() to be usable from places other than sha1_name.Libravatar Junio C Hamano1-8/+33
You can pass an extra argument to the function to receive the reflog message information. Also when the log does not go back beyond the point the user asked, the cut-off time and count are given back to the caller for emitting the error messages as appropriately. We could later add configuration for get_sha1_basic() to make it an error instead of it being just a warning. Signed-off-by: Junio C Hamano <junkio@cox.net>
2007-01-19refs.c::read_ref_at(): fix bogus munmap() call.Libravatar Junio C Hamano1-3/+5
The code uses mmap() to read reflog data, but moves the pointer around while reading, and uses that updated pointer in the call to munmap(). Signed-off-by: Junio C Hamano <junkio@cox.net>
