fede44b2e1 git-svn log: fix ascending revision ranges
Fixed typo in Git::SVN::Log::git_svn_log_cmd().  Previously a command like
"git-svn log -r1:4" would only show a commit log separator.

Added tests for ascending and descending revision ranges.

eb9d2b91cf Fix and improve t7004 (git-tag tests)
Brown paper bag fix to avoid using non portable sed syntax. The
test by itself didn't catch what it was supposed to, anyways.

The new test first checks if git-tag correctly errors out when
the user exited the editor without editing the file.  Then it
checks if what the user was presented in the editor was any
useful, which we define as the following:

 * It begins with a single blank line, where the invoked editor
   would typically place the editing curser at, so that the user
   can immediately start typing;

 * It has some instruction but that comes after that initial
   blank line, all lines prefixed with "#".  We specifically do
   not check for the wording of this instruction.

 * And it has nothing else, as the expected behaviour is "Hey
   you did not leave any message".

0e06cc8b82 Fix per-directory exclude handing for "git add"
In "dir_struct", each exclusion element in the exclusion stack records a
base string (pointer to the beginning with length) so that we can tell
where it came from, but this pointer is just pointing at the parameter
that is given by the caller to the push_exclude_per_directory()
function.

While read_directory_recursive() runs, calls to excluded() makes use
the data in the exclusion elements, including this base string.  The
caller of read_directory_recursive() is not supposed to free the
buffer it gave to push_exclude_per_directory() earlier, until it
returns.

The test case Bruce Stephens gave in the mailing list discussion
was simplified and added to the t3700 test.

dcf0c16ef1 core.excludesfile clean-up
There are inconsistencies in the way commands currently handle
the core.excludesfile configuration variable.  The problem is
the variable is too new to be noticed by anything other than
git-add and git-status.

 * git-ls-files does not notice any of the "ignore" files by
   default, as it predates the standardized set of ignore files.
   The calling scripts established the convention to use
   .git/info/exclude, .gitignore, and later core.excludesfile.

 * git-add and git-status know about it because they call
   add_excludes_from_file() directly with their own notion of
   which standard set of ignore files to use.  This is just a
   stupid duplication of code that need to be updated every time
   the definition of the standard set of ignore files is
   changed.

 * git-read-tree takes --exclude-per-directory=<gitignore>,
   not because the flexibility was needed.  Again, this was
   because the option predates the standardization of the ignore
   files.

 * git-merge-recursive uses hardcoded per-directory .gitignore
   and nothing else.  git-clean (scripted version) does not
   honor core.* because its call to underlying ls-files does not
   know about it.  git-clean in C (parked in 'pu') doesn't either.

We probably could change git-ls-files to use the standard set
when no excludes are specified on the command line and ignore
processing was asked, or something like that, but that will be a
change in semantics and might break people's scripts in a subtle
way.  I am somewhat reluctant to make such a change.

On the other hand, I think it makes perfect sense to fix
git-read-tree, git-merge-recursive and git-clean to follow the
same rule as other commands.  I do not think of a valid use case
to give an exclude-per-directory that is nonstandard to
read-tree command, outside a "negative" test in the t1004 test
script.

This patch is the first step to untangle this mess.

The next step would be to teach read-tree, merge-recursive and
clean (in C) to use setup_standard_excludes().

2587d67966 Fix t9101 test failure caused by Subversion "auto-props"
If a user has an "auto-prop" in his/her ~/.subversion/config file for
automatically setting the svn:keyword Id property on all ".c" files
(a reasonably common configuration in the Subversion world) then one
of the "svn propset" operations in the very first test would become a
no-op, which in turn would make the next commit a no-op.

This then caused the 25th test ('test propget') to fail because it
expects a certain number of commits to have taken place but the actual
number of commits was off by one.

Björn Steinbrink identified the "auto-prop" feature as the cause
of the failure. This patch avoids it by passing the "--no-auto-prop"
flag to "svn import" when setting up the test repository, thus ensuring
that the "svn propset" operation is no longer a no-op, regardless of the
users' settings in their config.

We sometimes pick out the original rfc822 'From' header and
include it in the body of the message. If the original
author's name needs encoding, then we should specify that in
the content-type header.

If we already had a content-type header in the mail, then we
may need to re-encode. The logic is there to detect
this case, but it doesn't actually do the re-encoding.

38f9f5ec41 git-p4: Fix direct import from perforce after fetching changes through git from origin
When using an existing git repository to cache the perforce import we don't
fetch the branch mapping from perforce as that is a slow operation. However
the origin repository may not be fully up-to-date and therefore it may be
necessary to import more changes directly from Perforce.

Such a direct import needs self.knownBranches to be set up though, so

7dc0fe3be5 Fix parent rewriting in --early-output
We cannot tell a node that has been checked and found not to be
interesting (which does not have the TREECHANGE flag) from a
node that hasn't been checked if it is interesting or not,
without relying on something else, such as object->parsed.

But an object can get the "parsed" flag for other reasons.
Which means that "TREECHANGE" has the wrong polarity.

This changes the way how the path pruning logic marks an
uninteresting commits.  From now on, we consider a commit
interesting by default, and explicitly mark the ones we decided
to prune.  The flag is renamed to "TREESAME".

Then, this fixes the logic to show the early output with
incomplete pruning.  It basically says "a commit that has
TREESAME set is kind-of-UNINTERESTING", but obviously in a
different way than an outright UNINTERESTING commit.  Until we
parse and examine enough parents to determine if a commit
becomes surely "kind-of-UNINTERESTING", we avoid rewriting
the ancestry so that later rounds can fix things up.

4d1012c370 Fix rev-list when showing objects involving submodules
The function mark_tree_uninteresting() assumed that the tree entries
are blob when they are not trees.  This is not so.  Since we do
not traverse into submodules (yet), the gitlinks should be ignored.

In general, we should try to start moving away from using the
"S_ISLNK()" like things for internal git state. It was a mistake to
just assume the numbers all were same across all systems in the first
place.  This implementation converts to the "object_type", and then
uses a case statement.

From version 1.72 it will replace all dots in roff requests with U+2302
("house" character), and add escaping in output for all instances of dot
that are not in roff requests. This caused the ".ft" hack forcing
monospace font in listingblocks to end up as "\&.ft" and being visible
in the resulting man page.

The fix adds a DOCBOOK_XSL_172 build variable that will disable the
hack. To allow this variable to be defined in config.mak it also moves
build variable handling below the inclusion of config.mak.

f141bd804d Handle broken vsnprintf implementations in strbuf
Solaris 9's vsnprintf implementation returns -1 if we pass it a
buffer of length 0.  The only way to get it to give us the actual
length necessary for the formatted string is to grow the buffer
out to have at least 1 byte available in the strbuf and then ask
it to compute the length.

If the available space is 0 I'm growing it out by 64 to ensure
we will get an accurate length estimate from all implementations.
Some callers may need to grow the strbuf again but 64 should be a
reasonable enough initial growth.

We also no longer silently fail to append to the string when we are
faced with a broken vsnprintf implementation.  On Solaris 9 this
silent failure caused me to no longer be able to execute "git clone"
as we tried to exec the empty string rather than "git-clone".

436e7a74c6 Don't allow fast-import tree delta chains to exceed maximum depth
Brian Downing noticed fast-import can produce tree depths of up
to 6,035 objects and even deeper.  Long delta chains can create
very small packfiles but cause problems during repacking as git
needs to unpack each tree to count the reachable blobs.

What's happening here is the active branch cache isn't big enough.
We're swapping out the branch and thus recycling the tree information
(struct tree_content) back into the free pool.  When we later reload
the tree we set the delta_depth to 0 but we kept the tree we just
reloaded as a delta base.

So if the tree we reloaded was already at the maximum depth we
wouldn't know it and make the new tree a delta.  Multiply the
number of times the branch cache has to swap out the tree times
max_depth (10) and you get the maximum delta depth of a tree created
by fast-import.  In Brian's case above the active branch cache had
to swap the branch out 603/604 times during this import to produce
a tree with a delta depth of 6035.

71aa2b8f0e Resurrect git-revert.sh example and add comment to builtin-revert.c
I had to scratch my head for quite some time figuring out why we
cannot optimize out write_tree() we do when --no-commit option
is given, whose purpose seem to be only to check if the index is
unmerged, with a simple loop over the active_cache[].

So add a comment to describe why the write_tree() is there, and
resurrect the last scripted version as a reference material in
contrib/example directory with others.

245de36f03 revert/cherry-pick: allow starting from dirty work tree.
There is no reason to forbid a dirty work tree when reverting or
cherry-picking a change, as long as the index is clean.

The scripted version used to allow it:

    case "$no_commit" in
    t)
    	# We do not intend to commit immediately.  We just want to
    	# merge the differences in.
    	head=$(git-write-tree) ||
    		die "Your index file is unmerged."
    	;;
    *)
    	head=$(git-rev-parse --verify HEAD) ||
    		die "You do not have a valid HEAD"
    	files=$(git-diff-index --cached --name-only $head) || exit
    	if [ "$files" ]; then
    		die "Dirty index: cannot $me (dirty: $files)"
    	fi
    	;;
    esac

but C rewrite tightened the check, probably by mistake.
