185c975faa Do not take mode bits from index after type change.
When we do not trust executable bit from lstat(2), we copied
existing ce_mode bits without checking if the filesystem object
is a regular file (which is the only thing we apply the "trust
executable bit" business) nor if the blob in the index is a
regular file (otherwise, we should do the same as registering a
new regular file, which is to default non-executable).

Noticed by Johannes Sixt.

7b3fab877d Work around Subversion race in git-svn tests.
Some of the git-svn tests can fail on fast machines due to a race in
Subversion: if a file is modified in the same second it was checked out
(or in for that matter), Subversion will not consider it modified. This
works around the problem by increasing the timestamp by one second
before each commit.

ea5e370aa9 fast-import: Support reusing 'from' and brown paper bag fix reset.
It was suggested on the mailing list that being able to use `from`
in any commit to reset the current branch is useful in some types of
importers, such as a darcs importer.

We originally did not permit resetting an existing branch with a
new `from` command during a `commit` command, but this restriction
was only to help debug the hacked up cvs2svn that Jon Smirl was
developing in parallel with git-fast-import.  It is probably more
of a problem to disallow it than to allow it.  So now we permit a
`from` during any `commit`.

While making the changes required to permit multiple `from`
commands on the same branch, I discovered we no longer needed the
last_commit field to be set to 0 during a reset, so that was removed.
(Reset was originally setting the field to 0 to signal cmd_from()
that it was OK to execute on the branch.)

While poking around in this section of fast-import I also realized
the `reset` command was not working as intended if the corresponding
`from` command was omitted (as allowed by the BNF grammar and the
code).  If `from` was omitted we cleared out the tree but we left
the tree SHA-1 and parent commit SHA-1 intact.  This is not what
the user intended in this case.  Instead they would be trying to
reset the branch to have no parent and to have no tree, making the
branch look new-born during the next commit.  We now clear these
SHA-1 values during `reset`, ensuring the branch looks new-born if
`from` does not get supplied.

New test cases for these were also added.

bdf1c06dc1 fast-import: Hide the pack boundary commits by default.
Most users don't need the pack boundary information that fast-import
was printing to standard output, especially if they were calling
it with --quiet.

Those users who do want this information probably want it captured
so they can go back and use it to repack the imported repository.
So dumping the boundary commits to a log file makes more sense then
printing them to standard output.

825769a8fe Teach fast-import how to clear the internal branch content.
Some frontends may not be able to (easily) keep track of which files
are included in the branch, and which aren't.  Performing this
tracking can be tedious and error prone for the frontend to do,
especially if its foreign data source cannot supply the changed
path list on a per-commit basis.

fast-import now allows a frontend to request that a branch's tree
be wiped clean (reset to the empty tree) at the start of a commit,
allowing the frontend to feed in all paths which belong on the branch.

This is ideal for a tar-file importer frontend, for example, as
the frontend just needs to reformat the tar data stream into a gfi
data stream, which may be something a few Perl regexps can take
care of. :)

7073e69e38 Don't do non-fastforward updates in fast-import.
If fast-import is being used to update an existing branch of
a repository, the user may not want to lose commits if another
process updates the same ref at the same time.  For example, the
user might be using fast-import to make just one or two commits
against a live branch.

We now perform a fast-forward check during the ref updating process.
If updating a branch would cause commits in that branch to be lost,
we skip over it and display the new SHA1 to standard error.

This new default behavior can be overridden with `--force`, like
git-push and git-fetch.

63e0c8b364 Support RFC 2822 date parsing in fast-import.
Since some frontends may be working with source material where
the dates are only readily available as RFC 2822 strings, it is
more friendly if fast-import exposes Git's parse_date() function
to handle the conversion.  This way the frontend doesn't need
to perform the parsing itself.

The new --date-format option to fast-import can be used by a
frontend to select which format it will supply date strings in.
The default is the standard `raw` Git format, which fast-import
has always supported.  Format rfc2822 can be used to activate the
parse_date() function instead.

Because fast-import could also be useful for creating new, current
commits, the format `now` is also supported to generate the current
system timestamp.  The implementation of `now` is a trivial call
to datestamp(), but is actually a whole whopping 3 lines so that
fast-import can verify the frontend really meant `now`.

As part of this change I have added validation of the `raw` date
format.  Prior to this change fast-import would accept anything
in a `committer` command, even if it was seriously malformed.
Now fast-import requires the '> ' near the end of the string and
verifies the timestamp is formatted properly.

1f7d1a53fe git-clone --reference: saner handling of borrowed symrefs.
When using --reference to borrow objects from a neighbouring
repository while cloning, we copy the entire set of refs under
temporary "refs/reference-tmp/refs" space and set up the object
alternates.  However, a textual symref copied this way would not
point at the right place, and causes later steps to emit error
messages (which is harmless but still alarming).  This is most
visible when using a clone created with the separate-remote
layout as a reference, because such a repository would have
refs/remotes/origin/HEAD with 'ref: refs/remotes/origin/master'
as its contents.

Although we do not create symbolic-link based refs anymore, they
have the same problem because they are always supposed to be
relative to refs/ hierarchy (we dereference by hand, so it only
is good for HEAD and nothing else).

In either case, the solution is simply to remove them after
copying under refs/reference-tmp; if a symref points at a true
ref, that true ref itself is enough to ensure that objects
reachable from it do not needlessly get fetched.

183d79724f Keep untracked files not involved in a merge.
My earlier fix (8371234e) to delete renamed tracked files from the
working directory also caused merge-recursive to delete untracked
files that were in the working directory.

The problem here is merge-recursive is deleting the working directory
file without regard for which branch it was associated with.  What we
really want to do during a merge is to only delete files that were
renamed by the branch we are merging into the current branch,
and that are still tracked by the current branch.  These files
definitely don't belong in the working directory anymore.

Anything else is either a merge conflict (already handled in other
parts of the code) or a file that is untracked by the current branch
and thus is not even participating in the merge.  Its this latter
class that must be left alone.

For this fix to work we are now assuming that the first non-base
argument passed to git-merge-recursive always corresponds to the
working directory.  This is already true for all in-tree callers
of merge-recursive.  This assumption is also supported by the
long time usage message of "<base> ... -- <head> <remote>", where
"<head>" is implied to be HEAD, which is generally assumed to be
the current tree-ish.

af7cf268f0 fetch-pack: remove --keep-auto and make it the default.
This makes git-fetch over git native protocol to automatically
decide to keep the downloaded pack if the fetch results in more
than 100 objects, just like receive-pack invoked by git-push

the downloaded pack as before.

The 100 threshold can be adjusted with fetch.unpacklimit

b715cfbba4 Accept 'inline' file data in fast-import commit structure.
Its very annoying to need to specify the file content ahead of a
commit and use marks to connect the individual blobs to the commit's
file modification entry, especially if the frontend can't/won't
generate the blob SHA1s itself.  Instead it would much easier to
use if we can accept the blob data at the same time as we receive
each file_change line.

Now fast-import accepts 'inline' instead of a mark idnum or blob
SHA1 within the 'M' type file_change command.  If an inline is
detected the very next line must be a 'data n' command, supplying

similar tests.  We'll see.

e66191f483 git-svn: fix tests to work with older svn
Some of the recent changes and shortcuts to the tests broke
things for people using older versions of svn:

t9104-git-svn-follow-parent.sh:
  v1.2.3 (from SuSE 10.0 as reported by riddochc on #git
  (thanks!)) required an extra 'svn up'.  I was also able to
  reproduce this with v1.1.4 (Debian Sarge).

lib-git-svn.sh:
  SVN::Repos bindings in versions up to and including 1.1.4
  (Sarge again) do not pass fs-config options to the underlying
  library.  BerkeleyDB repositories also seem completely broken
  on all my Sarge machines; so not using FSFS does not seem to
  be an option for most people.

5c94f87e6b use 'init' instead of 'init-db' for shipped docs and tools
While 'init-db' still is and probably will always remain a valid git
command for obvious backward compatibility reasons, it would be a good
idea to move shipped tools and docs to using 'init' instead.
