In commit dec543e (am -i, git-svn: use "git var GIT_PAGER"), I tried
to teach git svn to defer to git var on what pager to use. In the

- The value set for $pager in config_pager has local scope, so
run_pager never sees it;
- git var cannot tell whether git svn’s output is going to a

information.

In certain situations it may be necessary to manually remap an svn

o--- [git-svn clone]
/
[origin svn repo]
\
o--- [svnsync clone]
Imagine that only "git-svn clone" and "svnsync clone" are made available
to external users. Furthur, "git-svn clone" contains only trunk, and for
reasons unknown, "svnsync clone" is missing the revision properties that
normally provide the origin svn repo's UUID.
A git user who has cloned the "git-svn clone" repo now wishes to use
git-svn to pull in the missing branches from the "synsync clone" repo.
In order for git-svn to get the history correct for those branches,
it needs to know the origin svn repo's UUID. Hence rewriteUUID.

When recording the revisions that it has merged, SVN sets the top
revision to be the latest revision in the repository, which is not
necessarily a revision on the branch that is being merged from. When
it is not on the branch, git-svn fails to add the extra parent to
represent the merge because it relies on finding the commit on the
branch that corresponds to the top of the SVN merge range.
In order to correctly handle this case, we look for the maximum
revision less than or equal to the top of the SVN merge range that is
actually on the branch being merged from.

git-svn: add (failing) test for SVN 1.5+ merge with intervening commit
This test exposes a bug in git-svn's handling of SVN 1.5+ mergeinfo
properties. The problematic case is when there is some commit on an
unrelated branch after the last commit on the merged-from branch.
When SVN records the mergeinfo property, it records the latest
revision in the whole repository, which, in the problematic case, is
not on the branch it is merging from.
To trigger the git-svn bug, we modify t9151 to include two SVN merges,
the second of which has an intervening commit. The SVN dump was
generated using SVN 1.6.6 (on Debian squeeze amd64).

And then unescape them when writing to $GIT_CONFIG.
SVN has different rules for repository URLs (usually the root)
and for paths within that repository (below the HTTP layer).
Thus, for the request URI path at the HTTP level, the URI needs
to be encoded. However, in the body of the HTTP request (the
with underlying SVN XML protocol), those paths should not be
URI-encoded[1]. For non-HTTP(S) requests, SVN appears to be
more flexible and will except weird characters in the URL as
well as URI-encoded ones.
Since users are used to using URLs being entirely URI-encoded,
git svn will now attempt to unescape the path portion of URLs
while leaving the actual repository URL untouched.
This change will be reflected in newly-created $GIT_CONFIG files
only. This allows users to switch between svn(+ssh)://, file://
and http(s):// urls without changing the fetch/branches/tags
config keys. This won't affect existing imports at all (since
things didn't work before this commit anyways), and will allow
users to force escaping into repository paths that look like
they're escaped (but are not).

This argument is required if there are multiple branches (or tags) entries

Add a command to unwind the effects of fetch by moving the rev_map
and refs/remotes/git-svn back to an old SVN revision. This allows
revisions to be re-fetched. Ideally SVN revs would be immutable,
but permissions changes in the SVN repository or indiscriminate use
of '--ignore-paths' can create situations where fetch cannot make
progress.

'git svn dcommit' takes an optional revision argument, but the meaning
of it was rather scary. It completely ignored the current state of
the HEAD, only looking at the revisions between SVN and $rev. If HEAD
was attached to $branch, the branch lost all commits $rev..$branch in
the process.
Considering that 'git svn dcommit HEAD^' has the intuitive meaning
"dcommit all changes on my branch except the last one", we change the
meaning of the revision argument. git-svn temporarily checks out $rev
for its work, meaning that
* if a branch is specified, that branch (_not_ the HEAD) is rebased as
part of the dcommit,
* if some other revision is specified, as in the example, all work
happens on a detached HEAD and no branch is affected.

...without i18n.commitencoding set in the config.
SVN tries to store all commit messages in UTF-8, however it is
up to the job of the clients to enforce this rule. SVN servers
themselves do not always enforce this; allowing clients to
commit malformed UTF-8 messages and break repositories.
So git-svn will enforce this and tell the user to set
i18n.commitencoding when a git commit is is not in UTF-8.

Add a new option, --authors-prog, to git-svn that allows a more flexible
alternative (or supplement) to --authors-file. This allows more
advanced username operations than the authors file will allow. For
example, one may look up Subversion users via LDAP, or may generate the
name and email address from the Subversion username.
Notes:
* If both --authors-name and --authors-prog are given, the former is
tried first, falling back to the later.
* The program is called once per unique SVN username, and the result is
cached.
* The command-line argument must be the path to a program, not a generic
shell command line. The absolute path to this program is taken at
startup since the git-svn script changes directory during operation.
* The option is not enabled for `git svn log'.

The --ignore-paths option to fetch is very useful for working on a subset
of a SVN repository. For proper operation, every command that causes a
fetch (explicit or implied) must include a matching --ignore-paths option.
This patch adds a persistent svn-remote.$repo_id.ignore-paths config by
promoting Fetcher::is_path_ignored to a member function and initializing
$self->{ignore_regex} in Fetcher::new. Command line --ignore-paths is
still recognized and acts in addition to the config value.

To find the blob object name given a tree and pathname, we were

Unlike many command-line interfaces, the "--" alone does not
symbolize the end of non-option arguments on the command-line.
ls-tree interprets the "--" as a prefix to match against, thus
the entire contents of the --dashed/* hierarchy would be
returned because the "--" matches "--dashed" and every path

When initializing a git-svn repository from a Subversion repoository,
it is common to be interested in a path which did not exist in the
initial commit to Subversion. In a large repository, the initial fetch
may take some looking for the earliest existence of the path time while
the user receives no additional feedback. Print the highest revision
number scanned thus far to let the user know something is still
happening.

This will be useful when somebody want to checkout something partially from
repository with some non-standart layout or exclude some files from it.
Example: repository has structure /module-{a,b,c}/{trunk,branches,tags}/...
Modules are interdependent, and you want it to be single repostory (to commit
to all modules simultaneously and view complete history), but do not want
branches and tags be checked out into working copy.
Other use case is excluding some large blobs.
The quirk for now is that user must specify this option every fetch/rebase;
in other case he may get extra files or "file not found" errors. It may be
will be resolved by adding regular expression to .git/config into
[svn-remote ...] to make it persistent.
