git svn: make minimize URL more reliable over http(s)
In addition to path-based restrictions, Subversion servers over
http(s) may have access controls implemented via the LimitExcept
directive in Apache. In some cases, LimitExcept may be
(arguably) misconfigured to not allow REPORT requests while
allowing OPTIONS and PROPFIND.
This caused problems with our existing minimize_url logic that
only issued OPTIONS and PROPFIND requests when connecting and
using SVN::Ra::get_latest_revnum. We now call SVN::Ra::get_log
if get_latest_revnum succeeds, resulting in a REPORT request
being sent. This will increase our chances of tripping access
controls before we start attempting to fetch history.
Disable asciidoc 8.4.1+ semantics for `{plus}` and friends
asciidoc 8.4.1 changed the semantics of inline backtick quoting so
that they disable parsing of inline constructs, i.e.,
Input: `{plus}`
Pre 8.4.1: +
Post 8.4.1: {plus}
Fix this by defining the asciidoc attribute 'no-inline-literal'
(which, per the 8.4.1 changelog, is the toggle to return to the old
behaviour) when under ASCIIDOC8.

git svn: the branch command no longer needs the full path
This was introduced in 0b2af457a49e3b00d47d556d5301934d27909db8
("Fix branch detection when repository root is inaccessible")
but reintroduced in the previous commit.
git svn: revert default behavior for --minimize-url
This reverts the --minimize-url behavior change that
appeared recently in commit 0b2af457a49e3b00d47d556d5301934d27909db8
("Fix branch detection when repository root is inaccessible").
However, we now allow the option to be turned off by allowing
"--no-minimize-url" so people with limited-access setups can
still take advantage of the fix in 0b2af457a49e3b00d47d556d5301934d27909db8.
Also document the behavior and default settings of minimize-url
in the manpage for the first time.
This introduces a temporary UI regression to allow t9141 to pass
that will be reverted (fixed) in the next commit.
The second and third tests of this script expected that Russian strings
are converted between ISO-8859-5 and Shift_JIS in the "blame --porcelain"
format output correctly.
Sure, many platforms may convert between such a combination, but that is
only because one of the base character set of Shift_JIS, JIS X 0208,
defines codepoints for Russian characters (among others); I do not think
anybody uses Shift_JIS when seriously writing Russian, and it is perfectly
understandable if iconv() libraries on some platforms fail converting
between this combination, as it does not matter in reality.
This patch changes the test to verify Japanese strings are converted
correctly between EUC-JP and Shift_JIS in the same procedure. The point
of the test is not about verifying the platform's iconv() library, but to
see if "git blame" makes correct iconv() library calls when it should.
We could instead use ISO-8859-5 and KOI8-R as the combination, because
they are both meant to represent Russian, in order to make this test
meaningful on more platforms, but we already use Shift_JIS vs EUC-JP
combinations to test other programs in our test suite, so this combination
is safer from the point of view of the portability. Besides, I do not
read nor write Russian; sorry ;-)
This change allows tests to pass on my (friend's) Solaris 5.11 box.

The first "grep -C1" test in t7002 does not pass on my SunOS-5.11-i86pc,

does not define preprocessor macro __unix__ which made him always use the

Let's be more explicit and say that we do not use external grep on Suns.
When you have grafts that pretend that a given commit has different
parents than the ones recorded in the commit object, it is dangerous
to let 'git repack' remove those hidden parents, as you can easily
remove the graft and end up with a broken repository.
So let's play it safe and keep those parent objects and everything
that is reachable by them, in addition to the grafted parents.
As this behavior can only be triggered by git pack-objects, and as that
command handles duplicate parents gracefully, we do not bother to cull
duplicated parents that may result by using both true and grafted
parents.

git svn: fix shallow clone when upstream revision is too new
Thanks to Ka-Hing Cheung for the initial bug report and patch:
> git-svn uses $ra->get_latest_revnum to find out the latest
> revision, but that can be problematic, because get_latest_revnum
> returns the latest revnum in the entire repository, not

Relying on SVN::Core::INVALID_REVNUM (-1) as the "start"
argument to SVN::Ra::get_log() proved unreliable with http(s)
URLs so the result of SVN::Ra::get_latest_revnum() is used as
the "start" argument instead.
do_one_ref(): null_sha1 check is not about broken ref
f8948e2 (remote prune: warn dangling symrefs, 2009-02-08) introduced a
more dangerous variant of for_each_ref() family that skips the check for
dangling refs, but it also made another unrelated check optional by
mistake.
The check to see if a ref points at 0{40} is not about brokenness, but is
about a possible future plan to represent a deleted ref by writing 40 "0"
in a loose ref when there is a stale version of the same ref already in
.git/packed-refs, so that we can implement deletion of a ref without
having to rewrite the packed refs file excluding the ref being deleted.
This check has to live outside of the conditional.

configure.ac: rework/fix the NEEDS_RESOLV and NEEDS_LIBGEN tests
The "action" parameters for these two tests were supplied incorrectly for
the way the tests were implemented. The tests check whether a program
which calls hstrerror() or basename() successfully links when -lresolv or
-lgen are used, respectively. A successful linking would result in
NEEDS_RESOLV or NEEDS_LIBGEN being unset, and failure would result in
setting the respective variable.
Aside from that issue, the tests did not handle the case where neither
library was necessary for accessing the functions in question. So solve
both of these issues by re-working the two tests so that their form is like
the NEEDS_SOCKET test which attempts to link with just the c library, and
if it fails then assumes that the additional library is necessary and sets
the appropriate variable.
Also an entry in the config.mak.in file is necessary for the NEEDS_LIBGEN
variable to appear in the config.mak.autogen file with the value assigned
by the configure script. Without it, the generated shell script would
contain a snippet like this:
for ac_lib in ; do
...
which is incorrect.

diff --cc: a lost line at the beginning of the file is shown incorrectly
When combine-diff inspected the diff from one parent to the merge result,
it misinterpreted a header in the form @@ -l,k +0,0 @@.
This hunk header means that K lines were removed from the beginning of the
file, so the lost lines must be queued to the sline that represents the
first line of the merge result, but we incremented our pointer incorrectly
and ended up queuing it to the second line, which in turn made the lossage
appear _after_ the first line.
combine-diff.c: fix performance problem when folding common deleted lines
For a deleted line in a patch with the parent we are looking at, the
append_lost() function finds the same line among a run of lines that were
deleted from the same location by patches from parents we previously
checked. This is so that patches with two parents

While reading the second patch (that removes "two" and then "fyra"), after
finding where removal of the "two" matches, we need to find existing
removal of "fyra" (if exists) in the removal list, but the match has to
happen after all the existing matches (in this case "two"). The code used
a naïve O(n^2) algorithm to compute this by scanning the whole removal
list over and over again.
This patch remembers where the next scan should be started in the existing
removal list to avoid this.
In a rebase with --onto, the correct test for whether we can skip
rewriting a commit is if it is already on top of $ONTO, not $UPSTREAM.
Without --onto, this distinction does not exist and the behavior does
not change.
In a situation with two merged branches on a common base X:
X---o---o---o---M
\ /
x---x---x---x
Y
if we try to move the branches from their base on X to be based on Y,
so as to get
X
Y---o'--o'--o'--M'
\ /
x'--x'--x'--x'
then we fail. The command `git rebase -p --onto Y X M` moves only the
first-parent chain, like so:
X
\
x---x---x---x
\
Y---o'--o'--o'--M'
because it mistakenly drops the other branch(es) x---x---x---x from
the TODO file. This tests and fixes this behavior.

git svn: rename tests that had conflicting numbers
Some unrelated tests were developed simultaneously and resulted
in test numbers conflicting. To avoid difficulty when referring
to tests via the "tXXXX" convention, rename the newer tests.
When showing an annotated tag, "git show" will always
display the pointed-to object. However, it didn't separate

where the new object started. For example:

$ git show foo
tag foo

This patch respects and sets the rev.shown_one member to
prepend a blank line before showing a second item. We use
this member of rev_info instead of a local flag, because the
log_tree_commit we call into for showing commits already
respects and sets that flag. Meaning that everything will be
spaced properly if you intermix commits and tags, like:
$ git show v1.6.3 v1.6.2 HEAD
In that case, a single blank line will separate the first
tag, the commit it points to, the second tag, the commit
that one points to, and the final commit.
While we're at it, let's also support trees, so that even
something as crazy as
$ git show HEAD^{tree} HEAD~1^{tree} HEAD
will also be spaced in an easy-to-read way. However, we
intentionally do _not_ insert blank lines for blobs, so
that specifying multiple blobs gives a strict concatenation.

checkout -f: deal with a D/F conflict entry correctly
When we switch branches with "checkout -f", unpack_trees() feeds two
cache_entries to oneway_merge() function in its src[] array argument. The
zeroth entry comes from the current index, and the first entry represents
what the merge result should be, taken from the tree recorded in the
commit we are switching to.
When we have a blob (either regular file or a symlink) in the index and in
the work tree at path "foo", and the switched-to tree has "foo/bar",
i.e. "foo" becomes a directory, src[0] is obviously that blob currently
registered at "foo". Even though we do not have anything at "foo" in the
switched-to tree, src[1] is _not_ NULL in this case.
The unpack_trees() machinery places a special marker df_conflict_entry
to signal that no blob exists at "foo", but it will become a directory
that may have somthing underneath it (namely "foo/bar"), so a usual 3-way
merge can notice the situation.
But oneway_merge() codepath failed to notice this and passed the special
marker directly to merged_entry(). This happens to remove the "foo" in
the end because the df_conflict_entry does not have any name (hence the
"error" message) and its addition in add_index_entry() is rejected, but it
is wrong.

as an odd way of asking for a log. I realize I should just have used "git
log", but at the same time it does make perfect conceptual sense. After
all, you _could_ have done
git show HEAD HEAD~1 HEAD~2 HEAD~3 HEAD~4
and saying "git show HEAD~5.." is pretty natural. It's not like "git show"
only ever showed a single commit (or other object) before either! So
conceptually, giving a commit range is a very sensible operation, even
though you'd traditionally have used "git log" for that.
However, doing that currently results in an error
fatal: object ranges do not make sense when not walking revisions
which admittedly _also_ makes perfect sense - from an internal git
implementation standpoint in 'revision.c'.
However, I think that asking to show a range makes sense to a user, while
saying "object ranges no not make sense when not walking revisions" only
makes sense to a git developer.
So on the whole, of the two different "makes perfect sense" behaviors, I
think I originally picked the wrong one. And quite frankly, I don't really
see anybody actually _depending_ on that error case. So why not change it?
So rather than error out, just turn that non-walking error case into a
"silently turn on walking" instead.

git-svn: Fix branch detection when repository root is inaccessible
For the case of multiple projects sharing a single SVN repository, it is
common practice to create the standard SVN directory layout within a
subdirectory for each project. In such setups, access control is often
used to limit what projects a given user may access. git-svn failed to
detect branches (e.g. when passing --stdlayout to clone) because it
relied on having access to the root directory in the repository. This
patch solves this problem by making git-svn use paths relative to the
given repository URL instead of the repository root.

quickfetch(): Prevent overflow of the rev-list command line
quickfetch() calls rev-list to check whether the objects we are about to
fetch are already present in the repo (if so, we can skip the object fetch).
However, when there are many (~1000) refs to be fetched, the rev-list
command line grows larger than the maximum command line size on some systems
(32K in Windows). This causes rev-list to fail, making quickfetch() return
non-zero, which unnecessarily triggers the transport machinery. This somehow
causes fetch to fail with an exit code.
By using the --stdin option to rev-list (and feeding the object list to its
standard input), we prevent the overflow of the rev-list command line,
which causes quickfetch(), and subsequently the overall fetch, to succeed.
However, using rev-list --stdin is not entirely straightforward: rev-list
terminates immediately when encountering an unknown object, which can
trigger SIGPIPE if we are still writing object's to its standard input.
We therefore temporarily ignore SIGPIPE so that the fetch process is not
terminated.
The patch also contains a testcase to verify the fix (note that before
the patch, the testcase would only fail on msysGit).

a working snprintf(), but it is only provided when _NO_XOPEN5 evaluates
to zero, and this only happens if _XOPEN_SOURCE is defined which, as
mentioned above, prevents many other common functions and defines.
The broken snprintf will be worked around with SNPRINTF_RETURNS_BOGUS in
the Makefile in a later patch.

unpack-trees.c: work around run-time array initialization flaw on IRIX 6.5
The c99 MIPSpro Compiler version 7.4.4m on IRIX 6.5 does not properly
initialize run-time initialized arrays. An array which is initialized with
fewer elements than the length of the array should have the unitialized
elements initialized to zero. This compiler only initializes the remaining
elements when the last element is a static parameter. So work around it
by adding a "NULL" initialization parameter.

* lt/dir-cleanup:
Make index preloading check the whole path to the file
Export thread-safe version of 'has_symlink_leading_path()'
Prepare symlink caching for thread-safety
Avoid using 'lstat()' to figure out directories
Avoid doing extra 'lstat()'s for d_type if we have an up-to-date cache entry
Simplify read_directory[_recursive]() arguments
Add 'fill_directory()' helper function for directory traversal
For some reason there still are people who use the old style layout
to put everything in $(bindir). The previous commit breaks the install
for them, because it tries to unconditionally remove git from execdir
and cp/ln from bindir --- oops.
Make index preloading check the whole path to the file
This uses the new thread-safe 'threaded_has_symlink_leading_path()'
function to efficiently verify that the whole path leading up to the
filename is a proper path, and does not contain symlinks.
This makes 'ce_uptodate()' a much stronger guarantee: it no longer just
guarantees that the 'lstat()' of the path would match, it also means
that we know that people haven't played games with moving directories
around and covered it up with symlinks.

This doesn't actually change the external interfaces, so they are still
thread-unsafe, but it makes the code internally pass a pointer to a
local 'struct cache_def' around, so that the core code can be made
thread-safe.
The threaded index preloading will want to verify that the paths leading
up to a pathname are all real directories.

If we have an up-to-date index entry for a file in that directory, we
can know that the directories leading up to that file must be
directories. No need to do an lstat() on the directory.

When a git command executes a subcommand, it uses the "git
foo" form, which relies on finding "git" in the PATH.
Normally this should not be a problem, since the same "git"
that was used to invoke git in the first place will be
found. And if somebody invokes a "git" outside of the PATH
(e.g., by giving its absolute path), this case is already
covered: we put that absolute path onto the front of PATH.
However, if one is using "sudo", then sudo will execute the
"git" from the PATH, but pass along a restricted PATH that
may not contain the original "git" directory. In this case,
executing a subcommand will fail.
To solve this, we put the "git" wrapper itself into the
execdir; this directory is prepended to the PATH when git
starts, so the wrapper will always be found.

Stop the insanity with separate 'path' and 'base' arguments that must
match. We don't need that crazy interface any more, since we cleaned up
handling of 'path' in commit da4b3e8c28b1dc2b856d2555ac7bb47ab712598c.

Add 'fill_directory()' helper function for directory traversal
Most of the users of "read_directory()" actually want a much simpler
interface than the whole complex (but rather powerful) one.
In fact 'git add' had already largely abstracted out the core interface
issues into a private "fill_directory()" function that was largely
applicable almost as-is to a number of callers. Yes, 'git add' wants to
do some extra work of its own, specific to the add semantics, but we can
easily split that out, and use the core as a generic function.
This function does exactly that, and now that much simplified
'fill_directory()' function can be shared with a number of callers,
while also ensuring that the rather more complex calling conventions of
read_directory() are used by fewer call-sites.
This also makes the 'common_prefix()' helper function private to dir.c,
since all callers are now in that file.

git-format-patch prepends patches with a [PATCH x/n] prefix, but
mailinfo used to remove any number of square-bracket pairs and
the content between them. This prevents one from using a commit
subject like this:
[ and ] must be allowed as input
Removing the square bracket pair from this rather clumsily
constructed subject line loses important information, so we must
take care not to.
This patch causes the subject stripping to stop after it has
encountered one pair of square brackets.
One possible downside of this patch is that the patch-handling
programs will now fail at removing author-added square-brackets
to be removed, such as
[RFC][PATCH x/n]
However, since format-patch only adds one set of square brackets,
this behaviour is quite easily undesrstood and defended while the
previous behaviour is not.
