3facc60031 mergetools/p4merge: Handle "/dev/null"
p4merge does not properly handle the case where "/dev/null"
is passed as a filename.

Work it around by creating a temporary file for this purpose.

7bc0911d03 test-lib: Fix say_color () not to interpret \a\b\c in the message
When running with color disabled (e.g. under prove to produce TAP
output), say_color() helper function is defined to use echo to show
the message.  With a message that ends with "\c", echo is allowed to
interpret it as "Do not end the line with LF".

Use printf "%s\n" to emit the message literally.

44bc5ac71f svn test: escape peg revision separator using empty peg rev
This test script uses "svn cp" to create a branch with an @-sign in
its name:

	svn cp "pr ject/trunk" "pr ject/branches/not-a@{0}reflog"

That sets up for later tests that fetch the branch and check that git
svn mangles the refname appropriately.

Unfortunately, modern svn versions interpret path arguments with an
@-sign as an example of path@revision syntax (which pegs a path to a
particular revision) and truncate the path or error out with message
"svn: E205000: Syntax error parsing peg revision '{0}reflog'".

When using subversion 1.6.x, escaping the @ sign as %40 avoids trouble
(see 08fd28bb, 2010-07-08).  Newer versions are stricter:

	$ svn cp "$repo/pr ject/trunk" "$repo/pr ject/branches/not-a%40{reflog}"
	svn: E205000: Syntax error parsing peg revision '%7B0%7Dreflog'

The recommended method for escaping a literal @ sign in a path passed
to subversion is to add an empty peg revision at the end of the path
("branches/not-a@{0}reflog@").  Do that.

Pre-1.6.12 versions of Subversion probably treat the trailing @ as
another literal @-sign (svn issue 3651).  Luckily ever since
v1.8.0-rc0~155^2~7 (t9118: workaround inconsistency between SVN
versions, 2012-07-28) the test can survive that.

Tested with Debian Subversion 1.6.12dfsg-6 and 1.7.5-1 and r1395837
of Subversion trunk (1.8.x).

b8c78e2a9d git svn: work around SVN 1.7 mishandling of svn:special changes
Subversion represents symlinks as ordinary files with content starting
with "link " and the svn:special property set to "*".  Thus a file can
switch between being a symlink and a non-symlink simply by toggling
its svn:special property, and new checkouts will automatically write a
file of the appropriate type.  Likewise, in subversion 1.6 and older,
running "svn update" would notice changes in filetype and update the
working copy appropriately.

Starting in subversion 1.7 (issue 4091), changes to the svn:special
property trip an assertion instead:

	$ svn up svn-tree
	Updating 'svn-tree':
	svn: E235000: In file 'subversion/libsvn_wc/update_editor.c' \
	line 1583: assertion failed (action == svn_wc_conflict_action_edit \
	|| action == svn_wc_conflict_action_delete || action == \
	svn_wc_conflict_action_replace)

Revisions prepared with ordinary svn commands ("svn add" and not "svn
propset") don't trip this because they represent these filetype
changes using a replace operation, which is approximately equivalent
to removal followed by adding a new file and works fine.  Follow suit.

Noticed using t9100.  After this change, git-svn's file-to-symlink
changes are sent in a format that modern "svn update" can handle and
tests t9100.11-13 pass again.

727b6fc3ed log --grep: accept --basic-regexp and --perl-regexp
When we added the "--perl-regexp" option (or "-P") to "git grep", we
should have done the same for the commands in the "git log" family,
but somehow we forgot to do so.  This corrects it, but we will
reserve the short-and-sweet "-P" option for something else for now.

Also introduce the "--basic-regexp" option for completeness, so that
the "last one wins" principle can be used to defeat an earlier -E
option, e.g. "git log -E --basic-regexp --grep='<bre>'".  Note that
it cannot have the short "-G" option as the option is to grep in the
patch text in the context of "log" family.

15fabd1bbd builtin/grep.c: make configuration callback more reusable
The grep_config() function takes one instance of grep_opt as its
callback parameter, and populates it by running git_config().

This has three practical implications:

 - You have to have an instance of grep_opt already when you call
   the configuration, but that is not necessarily always true.  You
   may be trying to initialize the grep_filter member of rev_info,
   but are not ready to call init_revisions() on it yet.

 - It is not easy to enhance grep_config() in such a way to make it
   cascade to other callback functions to grab other variables in
   one call of git_config(); grep_config() can be cascaded into from
   other callbacks, but it has to be at the leaf level of a cascade.

 - If you ever need to use more than one instance of grep_opt, you
   will have to open and read the configuration file(s) every time
   you initialize them.

Rearrange the configuration mechanism and model it after how diff
configuration variables are handled.  An early call to git_config()
reads and remembers the values taken from the configuration in the
default "template", and a separate call to grep_init() uses this
template to instantiate a grep_opt.

The next step will be to move some of this out of this file so that
the other user of the grep machinery (i.e. "log") can use it.

If the marks file is not available or not plausible, regenerate it by
walking through the notes tree.  , i.e.  The plausibility check tests
if the highest revision in the marks file matches the revision of the
top ref. It doesn't ensure that the mark file is completely correct.

16a7185447 Add a svnrdump-simulator replaying a dump file for testing
To ease testing without depending on a reachable svn server, this
compact python script mimics parts of svnrdumps behaviour.  It
requires the remote url to start with sim://.

Start and end revisions are evaluated.  If the requested revision
doesn't exist, as it is the case with incremental imports, if no new
commit was added, it returns 1 (like svnrdump).

To allow using the same dump file for simulating multiple incremental
imports, the highest revision can be limited by setting the environment
variable SVNRMAX to that value. This simulates the situation where
higher revs don't exist yet.

If there is no next revision in the svn repo, svnrdump terminates with

weird, but there is no other way to know whether there is a new
revision in the svn repo.

On the start of an incremental import, the parent of the first commit
in the fast-import stream is set to the branch name to update. All
following commits specify their parent by a mark number. Previous mark
files are currently not reused.

Extend svndump and fast-export to allow passing the target ref.
Update svn-fe to be compatible.

19ba02af47 When debug==1, start fast-import with "--stats" instead of "--quiet"
fast-import prints statistics that could be interesting to the
developer of remote helpers.

bfc366d931 Connect fast-import to the remote-helper via pipe, adding 'bidi-import' capability
The fast-import commands 'cat-blob' and 'ls' can be used by
remote-helpers to retrieve information about blobs and trees that
already exist in fast-import's memory. This requires a channel from
fast-import to the remote-helper.

remote-helpers that use these features shall advertise the new
'bidi-import' capability to signal that they require the communication
channel.  When forking fast-import in transport-helper.c connect it to
a dup of the remote-helper's stdin-pipe. The additional file
descriptor is passed to fast-import via its command line
(--cat-blob-fd).  It follows that git and fast-import are connected to
the remote-helpers's stdin.

Because git can send multiple commands to the remote-helper on it's
stdin, it is required that helpers that advertise 'bidi-import' buffer
all input commands until the batch of 'import' commands is ended by a
newline before sending data to fast-import.  This is to prevent mixing
commands and fast-import responses on the helper's stdin.

df7428eca4 Add argv_array_detach and argv_array_free_detached
Allow detaching of ownership of the argv_array's contents and add a
function to free those detached argv_arrays later.

This makes it possible to use argv_array efficiently with the exiting
struct child_process which only contains a member char **argv.

Add to documentation.
