ed35dece27 Read cvsimport options from repo-config
Default values for command line options can be saved in .git/config (or the
global ~/.gitconfig). Config option names match the command line option names,
so cvsimport.d corresponds to git-cvsimport -d. One may also set
cvsimport.module to specify a default cvs module name.

6211988f77 cvsimport: skip commits that are too recent
With this patch, cvsimport will skip commits made
in the last 10 minutes. The recent-ness test is of
5 minutes + cvsps fuzz window (5 minutes default).

When working with a CVS repository that is in use,
importing commits that are too recent can lead to
partially incorrect trees. This is mainly due to

 - Commits that are within the cvsps fuzz window may later
   be found to have affected more files.

 - When performing incremental imports, clock drift between
   the systems may lead to skipped commits.

This commit helps keep incremental imports of in-use
CVS repositories sane.

73bcf53342 git-cvsimport: add support for CVS pserver method HTTP/1.x proxying
This patch adds support for 'proxy' and 'proxyport' connection options
when using the pserver method for the CVS Root.

It has been tested with a Squid 2.5.x proxy server.

Quoting from the CVS info manual:

     The `gserver' and `pserver' connection methods all accept optional
  method options, specified as part of the METHOD string, like so:

       :METHOD[;OPTION=ARG...]:

     Currently, the only two valid connection options are `proxy', which
  takes a hostname as an argument, and `proxyport', which takes a port
  number as an argument.  These options can be used to connect via an HTTP
  tunnel style web proxy.  For example, to connect pserver via a web proxy
  at www.myproxy.net and port 8000, you would use a method of:

       :pserver;proxy=www.myproxy.net;proxyport=8000:

     *NOTE: The rest of the connection string is required to connect to
  the server as noted in the upcoming sections on password authentication,
  gserver and kserver.  The example above would only modify the METHOD
  portion of the repository name.*

     PROXY must be supplied to connect to a CVS server via a proxy
  server, but PROXYPORT will default to port 8080 if not supplied.
  PROXYPORT may also be set via the CVS_PROXY_PORT environment variable.

efe4abd14c Run "git repack -a -d" once more at end, if there's 1MB or more of not-packed data.
Although I converted upstream coreutils to git last month, I just
reconverted coreutils once again, as a test, and ended up with a
git repository of about 130MB (contrast with my packed git repo of
size 52MB).  That was because there were a lot of commits (but < 1024)
after the final automatic "git-repack -a -d".

Running a final
  git-repack -a -d && git-prune-packed
cut the final repository size down to the expected size.

So this looks like an easy way to improve git-cvsimport.
Just run "git repack ..." at the end if there's more than
some reasonable amount of not-packed data.

My choice of 1MB is a little arbitrarily.  I wouldn't mind missing
the minimal repo size by 1MB.  At the other end of the spectrum,
it's probably not worthwhile to pack everything when the total
repository size is less than 1MB.

Here's the patch:

1f24c58724 cvsimport: move over to using git-for-each-ref to read refs.
cvsimport opens all of the files in $GIT_DIR/refs/heads and reads
out the sha1's in order to work out what time the last commit on
that branch was made (in CVS) thus allowing incremental updates.
However, this takes no account of hierachical refs naming producing
the following error for each directory in $GIT_DIR/refs:

  Use of uninitialized value in chomp at /usr/bin/git-cvsimport line 503.
  Use of uninitialized value in concatenation (.) or string at
					/usr/bin/git-cvsimport line 505.
  usage: git-cat-file [-t|-s|-e|-p|<type>] <sha1>

Take advantage of the new packed refs work to use the new
for-each-ref iterator to get this information.

2f57c69792 cvsimport: complete the cvsps run before starting the import
We now capture the output of cvsps to a tempfile, and then read it in.
cvsps 2.1 works quite a bit "in memory", and only prints its patchset
info once it has finished talking with cvs, but apparently retaining
all that memory allocation. With this patch, cvsps is finished and
reaped before cvsimport start working (and growing). So the footprint
of the whole process is much lower.

e73aefe4fd cvsimport: cleanup commit function
This change attempts to clean up the commit function to make it a bit
easier to read (or at least the first half of it). It also improves
robustness and performance. Specifically:
  - report get_headref errors on opening ref unless the error is ENOENT
  - use regex to check for sha1 instead of length
  - use lexically scoped filehandles which get cleaned up automagically
  - check for error on both 'print' and 'close' (since output is buffered)
  - avoid "fork, do some perl, then exec" in commit(). It's not necessary,
    and we probably end up COW'ing parts of the perl process. Plus the code
    is much smaller because we can use open2()
  - avoid calling strftime over and over (mainly a readability cleanup)

8a5f2eac52 cvsimport: honor -i and non -i upon subsequent imports
Documentation says -i is "import only", so without it,
subsequent import should update the current branch and working
tree files in a sensible way.

"A sensible way" defined by this commit is "act as if it is a
git pull from foreign repository which happens to be CVS not
git".  So:

 - If importing into the current branch (note that cvsimport
   requires the tracking branch is pristine -- you checked out
   the tracking branch but it is your responsibility not to make
   your own commits there), fast forward the branch head and
   match the index and working tree using two-way merge, just
   like "git pull" does.

 - If importing into a separate tracking branch, update that
   branch head, and merge it into your current branch, again,
   just like "git pull" does.

The read_author_info() subroutine is taught to also understand

to ease migration for CVS users, who can use the -A option
to read from existing CVSROOT/users file.  write_author_info()

  (1) git-*-script are no more.  The commands installed do not

  (2) Many command names with 'cache' in them are renamed with
