Junio C Hamano 774751a8bc Re-fix "builtin-commit: fix --signoff"
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.

Steffen Prohaska 605b4978a1 refactor fetch's ref matching to use refname_match()
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.

Steffen Prohaska 79803322c1 add refname_match()
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.

Shawn O. Pearce dc49cd769b Cast 64 bit off_t to 32 bit size_t
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.

we specifically do not want to say having less than two levels
in the name is illegal to allow HEAD (and perhaps other special

Nicolas Pitre 1655707c9e lock_ref_sha1_basic(): remember the original name of a ref when resolving it
A ref might be pointing to another ref but only the name of the last ref
is remembered.  Let's remember about the first name as well.

Nicolas Pitre 9a13f0b71b make reflog filename independent from struct ref_lock
This allows for ref_log_write() to be used in a more flexible way,
and is needed for future changes.

This is only code reorg with no behavior change.

Junio C Hamano 8ac65937d0 Make sure we do not write bogus reflog entries.
The file format dictates that entries are LF terminated so
the message cannot have one in it.  Chomp the message to make
sure it only has a single line if necessary, while removing the
leading whitespace.

Junio C Hamano cb280e1075 Allow non-developer to clone, checkout and fetch more easily.
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.

Junio C Hamano 76a44c5c0b show-branch --reflog: show the reflog message at the top.
This changes the output so the list at the top shows the reflog
message, along with their relative timestamps.

You can use --reflog=<n> to show <n> most recent log entries, or
use --reflog=<n>,<b> to show <n> entries going back from the
entry <b>.  <b> can be either a number (so --reflog=4,20 shows 4
records starting from @{20}) or a timestamp (e.g. --reflog='4,1 day').

Here is a sample output (with --list option):

  $ git show-branch --reflog=10 --list jc/show-reflog
    [jc/show-reflog@{0}] (3 minutes ago) commit (amend): show-branch --ref
    [jc/show-reflog@{1}] (5 minutes ago) reset HEAD^

    [jc/show-reflog@{8}] (18 minutes ago) reset --hard HEAD~4

This shows what I did more cleanly:

At @{9}, I had a commit to complete 5 patch series, but I wanted
to consolidate two commits that enhances read_ref_at() into one
(they were @{9}^ and @{9}~3), and another two that touch show-branch
into one (@{9} and @{9}~2).

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.

Junio C Hamano 16d7cc90dd Extend read_ref_at() to be usable from places other than sha1_name.
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.
