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.

The configuration handling is a library-ish part of this program,

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.

fast-import mark files are stored outside the object database and are
therefore not fetched and can be lost somehow else. marks provide a
svn revision --> git sha1 mapping, while the notes that are attached

mapping.
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.

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.

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.

Enable basic fetching from subversion repositories. When processing
remote URLs starting with testsvn::, git invokes this remote-helper.
It starts svnrdump to extract revisions from the subversion repository
in the 'dump file format', and converts them to a git-fast-import stream
using the functions of vcs-svn/.
Imported refs are created in a private namespace at
refs/svn/<remote-name>/master. The revision history is imported
linearly (no branch detection) and completely, i.e. from revision 0 to
HEAD.
The 'bidi-import' capability is used. The remote-helper expects data
from fast-import on its stdin. It buffers a batch of 'import' command
lines in a string_list before starting to process them.

Subversion's svn_dirent_canonicalize() and svn_path_canonicalize()
APIs keep a leading slash in the return value if one was present on
the argument, which can be useful since it allows relative and
absolute paths to be distinguished.
When git-svn's canonicalize_path() learned to use these functions if
available, its semantics changed in the corresponding way. Some new
callers rely on the leading slash --- for example, if the slash is
stripped out then _canonicalize_url_ourselves() will transform
"proto://host/path/to/resource" to "proto://hostpath/to/resource".
Unfortunately the fallback _canonicalize_path_ourselves(), used when
the appropriate SVN APIs are not usable, still follows the old
semantics, so if that code path is exercised then it breaks. Fix it
to follow the new convention.
Noticed by forcing the fallback on and running tests. Without this
patch, t9101.4 fails:
Bad URL passed to RA layer: Unable to open an ra_local session to \

When using the {word,[...]} style of configuration for tags and branches,
it appears the intent is to only match whole path parts, since the words
in the {} pattern are meta-character quoted.
When the pattern word appears in the beginning or middle of the url,
it's matched completely, since the left side, pattern, and (non-empty)
right side are joined together with path separators.
However, when the pattern word appears at the end of the URL, the
right side is an empty pattern, and the resulting regex matches
more than just the specified pattern.
For example, if you specify something along the lines of
branches = branches/project/{release_1,release_2}
and your repository also contains "branches/project/release_1_2", you
will also get the release_1_2 branch. By restricting the match regex
with anchors, this is avoided.

When upload-pack advertises refs, we attempt to peel tags
and advertise the peeled version. We currently hand-roll the
tag dereferencing, and use as many optimizations as we can
to avoid loading non-tag objects into memory.
Not only has peel_ref recently learned these optimizations,
too, but it also contains an even more important one: it
has access to the "peeled" data from the pack-refs file.
That means we can avoid not only loading annotated tags
entirely, but also avoid doing any kind of object lookup at
all.
This cut the CPU time to advertise refs by 50% in the
linux-2.6 repo, as measured by:
echo 0000 | git-upload-pack . >/dev/null
best-of-five, warm cache, objects and refs fully packed:
[before] [after]
real 0m0.026s real 0m0.013s
user 0m0.024s user 0m0.008s
sys 0m0.000s sys 0m0.000s
Those numbers are irrelevantly small compared to an actual
fetch. Here's a larger repo (400K refs, of which 12K are
unique, and of which only 107 are unique annotated tags):
[before] [after]
real 0m0.704s real 0m0.596s
user 0m0.600s user 0m0.496s
sys 0m0.096s sys 0m0.092s
This shows only a 15% speedup (mostly because it has fewer
actual tags to parse), but a larger absolute value (100ms,
which isn't a lot compared to a real fetch, but this
advertisement happens on every fetch, even if the client is
just finding out they are completely up to date).
In truly pathological cases, where you have a large number
of unique annotated tags, it can make an even bigger
difference. Here are the numbers for a linux-2.6 repository
that has had every seventh commit tagged (so about 50K
tags):
[before] [after]
real 0m0.443s real 0m0.097s
user 0m0.416s user 0m0.080s

The point of peel_ref is to dereference tags; if the base
object is not a tag, then we can return early without even
loading the object into memory.
This patch accomplishes that by checking sha1_object_info
for the type. For a packed object, we can get away with just
looking in the pack index. For a loose object, we only need
to inflate the first couple of header bytes.
This is a bit of a gamble; if we do find a tag object, then
we will end up loading the content anyway, and the extra
lookup will have been wasteful. However, if it is not a tag
object, then we save loading the object entirely. Depending
on the ratio of non-tags to tags in the input, this can be a
minor win or minor loss.
However, it does give us one potential major win: if a ref
points to a large blob (e.g., via an unannotated tag), then
we can avoid looking at it entirely.
