There were a few calls to adjust_shared_perm() that were
missing:
- init-db creates refs, refs/heads, and refs/tags before
reading from templates that could specify sharedrepository in
the config file;
- updating config file created it under user's umask without
adjusting;
- updating refs created it under user's umask without
adjusting;
- switching branches created .git/HEAD under user's umask
without adjusting.
This moves adjust_shared_perm() from sha1_file.c to path.c,
since a few SIMPLE_PROGRAM need to call repository configuration
functions which in turn need to call adjust_shared_perm().
sha1_file.c needs to link with SHA1 computation library which
is usually not linked to SIMPLE_PROGRAM.

A few style fixes to get the code in line with the rest.
- asterisk to make a type a pointer to something goes in front
of the variable, not at the end of the base type.
E.g. a pointer to an integer is "int *ip", not "int* ip".
- open parenthesis for function parameter list, unlike
syntactic constructs, comes immediately after the function
name. E.g. "if (foo) bar();" not "if(foo) bar ();".
- "else" does not come on the same line as the closing brace of
corresponding "if".
The style is mostly a matter of personal taste, and people may
disagree, but consistency is important.

This updates the ref locking code to use creat-rename locking
code we use for the index file, so that it can borrow the code
to clean things up upon signals and program termination.

My earlier attempt at forcing a write for non-existant refs worked;
it forced a write for pretty much all refs. This corrects the
condition to only force a write for refs which don't exist yet.

If a ref is changed by http-fetch, local-fetch or ssh-fetch
record the change and the remote URL/name in the log for the ref.
This requires loading the config file to check logAllRefUpdates.
Also fixed a bug in the ref lock generation; the log file name was
not being produced right due to a bad prefix length.

Normally we try to skip writing a ref if its value hasn't changed
but in the special case that the ref doesn't exist but the new
value is going to be 0{40} then force writing the ref anyway.

Corrected the log starting time displayed in the error message
(as it was always showing the epoch due to a bad input to strtoul).
Improved the log parser so we only scan backwards towards the
'\n' from the end of the prior log; during this scan the last '>'
is remembered to improve performance (rather than scanning forward
to it).
If the log record matched is the last log record in the file only
use its new sha1 value if the date matches exactly; otherwise we
leave the passed in sha1 alone as it already contains the current
value of the ref. This way lookups of dates later than the log
end to stick with the current ref value in case the ref was updated
without logging.
If it looks like someone changed the ref without logging it and we
are going to return the sha1 which should have been valid during
the missing period then warn the user that there might be log data
missing and thus their query result may not be accurate. The check
isn't perfect as its just based on comparing the old and new sha1
values between the two log records but its better than not checking
at all.
Implemented test cases based on git-rev-parse for most of the
boundary conditions.

The log parser was only ever matching the last log record due to
calling strtoul on "> 1136091609" rather than " 1136091609". Also
once a match for '@' has been found after the name of the ref there
is no point in looking for another '@' within the remaining text.

Extended sha1 expressions may now include date specifications
which indicate a point in time within the local repository's
history. If the ref indicated to the left of '@' has a log in
$GIT_DIR/logs/<ref> then the value of the ref at the time indicated
by the specification is obtained from the ref's log.

If config parameter core.logAllRefUpdates is true or the log
file already exists then append a line to ".git/logs/refs/<ref>"
whenever git-update-ref <ref> is executed. Each log line contains
the following information:
oldsha1 <SP> newsha1 <SP> committer <LF>
where committer is the current user, date, time and timezone in
the standard GIT ident format. If the caller is unable to append
to the log file then git-update-ref will fail without updating <ref>.
An optional message may be included in the log line with the -m flag.

Created 'struct ref_lock' to contain the data necessary to perform
a ref update. This change improves writing a ref as the file names
are generated only once (rather than twice) and supports following
symrefs (up to the maximum depth). Further the ref_lock structure
provides room to extend the update API with ref logging.

"git branch" uses "rev-parse --all" and becomes much too slow when

This makes git-check-ref-format fail for "HEAD". Since the check is only
executed when creating refs, the existing symbolic ref is safe.
Otherwise these commands, most likely are pilot errors, would do
pretty funky stuff:
git checkout -b HEAD
git pull . other:HEAD

This should force git-daemon administrator's job a bit harder
because the exact paths need to be given in the whitelist, but
at the same time makes the auditing easier.
This moves validate_symref() from refs.c to path.c, because we
need to link path.c with git-daemon for its "enter_repo()", but
we do not want to link the daemon with the rest of git libraries
and its requirements.

This allows you to force git to avoid symlinks for refs. Just add
something like
[core]
symrefsonly = true
to .git/config.

Update check_ref_format() function to reject ref names that:
* has a path component that begins with a ".", or
* has a double dots "..", or
* has ASCII control character, "~", "^", ":" or SP, anywhere, or
* ends with a "/".
Use it in 'git-checkout -b', 'git-branch', and 'git-tag' to make sure
that newly created refs are well-formed.

Do our own ctype.h, just to get the sane semantics: we want

This adds the counterpart of git-update-ref that lets you read
and create "symbolic refs". By default it uses a symbolic link
to represent ".git/HEAD -> refs/heads/master", but it can be compiled
to use the textfile symbolic ref.
The places that did 'readlink .git/HEAD' and 'ln -s refs/heads/blah
.git/HEAD' have been converted to use new git-symbolic-ref command, so
that they can deal with either implementation.

This extends the ref reading to understand a "symbolic ref": a ref file
that starts with "ref: " and points to another ref file, and thus
introduces the notion of ref aliases.
This is in preparation of allowing HEAD to eventually not be a symlink,
but one of these symbolic refs instead.
[jc: Linus originally required the prefix to be "ref: " five bytes
and nothing else, but I changed it to allow and strip any number of
leading whitespaces to match what update-ref.c does.]

Because there is no reason not to, and this makes things a bit
safer when running "git prune".
[jc: I do not necessarily agree with the reasoning of the
original author that it is a good way to keep "git prune" from
stomping on objects to have a symlink that points at .git/refs
of the repository A in the .git/refs of the repository B when
repository A borrows object database from repository B. For one
thing, the object database that everybody borrows objects from
may not even have its own .git/refs hierarchy. Come to think of
it, maybe we should disallow symlink inside .git/refs hierarchy;
we update the files there by creat/rename pair, so having
symlinks would not work anyway when you do anything that would
update them.]

GCC's format __attribute__ is good for checking errors, especially
with -Wformat=2 parameter. This fixes most of the reported problems

It always uses a git-relative pathname, ie "refs/heads/master" instead of
".git/refs/heads/master" or whatever your GIT_DIR might be.
This way when we send refs back-and-forth between repositories, there's
never any question about GIT_DIR on either side.

It did a "for_each_ref()" in addition to the HEAD case, which was a
left-over from an early broken test.
|
|
"git_path()" returns a static pathname pointer into the git directory
using a printf-like format specifier.
"head_ref()" works like "for_each_ref()", except for just the HEAD.
|
|
Remove the "./" at the head, it just looks much nicer.
|
|
It needed to take the GIT_DIR information into account, something that
the original receive-pack usage just never cared about.
|
|
This turns it into a generic "do xyz for each ref" library function.
