The change in 6e9c4d408d ("git-cvsexportcommit: port to SHA-256",
2020-06-22) added the use of a temporary directory for the index.
However, the form we used doesn't work in versions of Perl before
5.10.1. For example, version 5.10.0 contains a version of File::Temp
from 2007 that doesn't contain "newdir".
In order to make the code work with 5.8.8, which we support, let's
change to use the static method "tempdir" with the argument "CLEANUP",
which provides the same behavior.

When we apply a binary patch, we must have the full object ID in the
header in order to apply it; without that, any attempt to apply it will
fail. If we set GIT_DIR to empty, git apply does not know about the
hash algorithm we're using, and consequently any attempt to apply a
patch using SHA-256 will fail, since the object ID is the wrong length.
The reason we set the GIT_DIR environment variable is because we don't
want to modify the index; we just want to know whether the patch
applies. Instead, let's just use a temporary file for the index, which
will be cleaned up automatically when the object goes out of scope.
Additionally, read the configuration for the repository and compute the
length of an object ID based on it. Use that when matching object IDs
with a regex or computing the all-zeros object ID.

Due to MSYS path mangling GIT_DIR contains a Windows-style path when
checked inside a Perl script even if GIT_DIR was previously set to an
MSYS-style path in a shell script. So explicitly convert to an MSYS-style
path before calling Perl's rel2abs() to make it work.
This fix was inspired by a very similar patch in WebKit:

Change the Perl scripts to turn on lexical warnings instead of setting
the global $^W variable via the -w switch.
The -w sets warnings for all code that interpreter runs, while "use
warnings" is lexically scoped. The former is probably not what the
authors wanted.
As an auxiliary benefit it's now possible to build Git with:
PERL_PATH='/usr/bin/env perl'
Which would previously result in failures, since "#!/usr/bin/env perl -w"
doesn't work as a shebang.

Formalize our dependency on perl 5.8, bumped from 5.6.[12]. We already
used the three-arg form of open() which was introduced in 5.6.1, but
t/t9700/test.pl explicitly depended on 5.6.2.
However git-add--interactive.pl has been failing on the 5.6 line since
it was introduced in v1.5.0-rc0~12^2~2 back in 2006 due to this open
syntax:
sub run_cmd_pipe {
my $fh = undef;
open($fh, '-|', @_) or die;
return <$fh>;
}
Which when executed dies on "Can't use an undefined value as
filehandle reference". Several of our tests also fail on 5.6 (even
more when compiled with NO_PERL_MAKEMAKER=1):
t2016-checkout-patch.sh
t3904-stash-patch.sh
t3701-add-interactive.sh
t7105-reset-patch.sh
t7501-commit.sh
t9700-perl-git.sh
Our code is bitrotting on 5.6 with no-one interested in fixing it, and
pinning us to such an ancient release of Perl is keeping us from using
useful features introduced in the 5.8 release.
The 5.6 series is now over 10 years old, and the 5.6.2 maintenance
release almost 7. 5.8 on the other hand is more than 8 years old.
All the modern Unix-like operating systems have now upgraded to it or
a later version, and 5.8 packages are available for old IRIX, AIX
Solaris and Tru64 systems.

working tree before applying commit patch
Depending on how your CVS->GIT conversion went you will have some
unexpanded CVS keywords in your GIT repo. If any of your git commits
touch these lines then the patch application will fail. This patch
addresses that by adding an option that will revert and expanded CVS
keywords to files in the working CVS directory that are affected by
the commit being applied.

If a file X is removed from CVS, it goes into the Attic directory, and CVS
reports it as 'no file X' but with status 'Up-to-date'. cvsexportcommit
misinterprets this as an existing file and tries to commit a file with the
same name. Correctly identify these files, so that new files with the
same name can be committed.
Add a test to t9200-git-cvsexportcommit.sh, which tests that we can
re-commit a removed filename which remains in CVS's attic. This adds a
file 'attic_gremlin' in CVS, then "removes" it, then tries to commit a
file with the same name from git.

When you misuse a git command, you are shown the usage string.
But this is currently shown in the dashed form. So if you just
copy what you see, it will not work, when the dashed form
is no longer supported.
This patch makes git commands show the dash-less version.
For shell scripts that do not specify OPTIONS_SPEC, git-sh-setup.sh

If you have a CVS checkout, it is easy to import the CVS history by
calling "git cvsimport". However, interacting with the CVS repository
using "git cvsexportcommit" was cumbersome, since that script assumes
separate working directories for Git and CVS.
Now, you can call cvsexportcommit with the -W option. This will
automatically discover the GIT_DIR, and it will check out the parent
commit before exporting the commit.
The intended workflow is this:
$ CVSROOT=$URL cvs co module
$ cd module
$ git cvsimport
hack, hack, hack, making two commits, cleaning them up using rebase -i.
$ git cvsexportcommit -W -c -p -u HEAD^
$ git cvsexportcommit -W -c -p -u HEAD

In commit fef3a7cc(cvsexportcommit: be graceful when "cvs status"
reorders the arguments), caution was taken to get the status even
for files with leading or trailing whitespace.
However, the author of that commit missed that chomp() removes only
trailing newlines. With help of the mailing list, the author realized
his mistake and provided this patch.
The idea is that we do not want to rely on a certain layout of the
output of "cvs status". Therefore we only call it with files that are
unambiguous after stripping leading and trailing whitespace.

In my use cases, "cvs status" sometimes reordered the passed filenames,
which often led to a misdetection of a dirty state (when it was in
reality a clean state).
I finally tracked it down to two filenames having the same basename.
So no longer trust the order of the results blindly, but actually check
the file name.
Since "cvs status" only returns the basename (and the complete path on the
server which is useless for our purposes), run "cvs status" several times
with lists consisting of files with unique (chomped) basenames.
Be a bit clever about new files: these are reported as "no file <blabla>",
so in order to discern it from existing files, prepend "no file " to the
basename.
In other words, one call to "cvs status" will not ask for two files
"blabla" (which does not yet exist) and "no file blabla" (which exists).
This patch makes cvsexportcommit slightly slower, when the list of changed
files has non-unique basenames, but at least it is accurate now.

When using the '-w $cvsdir' option to cvsexportcommit, it will chdir into
$cvsdir before executing several other git commands. If $GIT_DIR is set to
a relative path (e.g. '.'), the git commands executed by cvsexportcommit
will naturally fail.
Therefore, ensure that $GIT_DIR is absolute before the chdir to $cvsdir.

Because we feed the changed filenames to CVS on the command
line, it was possible for massive commits to overflow the
system exec limits. Instead, we now do an xargs-like split
of the arguments.
This means that we lose some of the atomicity of calling CVS
in one shot. Since CVS commits are not atomic, but the CVS
protocol is, the possible effects of this are not clear;
however, since CVS doesn't provide a different interface,
this is our only option for large commits (short of writing
a CVS client library).
The argument size limit is arbitrarily set to 64kB. This
should be high enough to trigger only in rare cases where it
is necessary, so normal-sized commits are not affected by
the atomicity change.

If git cvsexportcommit is executed fast enough in sequence, the CVS
timestamps could end up being the same. CVS tries to fix this
by sleeping until the CPU clock changes seconds. Unfortunately,
the CPU clock and the file system clock are not necessarily the same, so
the timestamps could be the same anyway. When that happens CVS may not
recognize changed files and cvs will forget to commit some files.

Unlike 'patch --fuzz=NUM', which specifies the number of lines allowed

This patch uses git-apply to do the patching which simplifies the code a lot
and also uses one pass to git-diff. git-apply gives information on added,
removed files as well as which files are binary.
Removed the test for checking for matching binary files when deleting them
since git-apply happily deletes the file. This is matter of taste since we
allow some fuzz for text patches also.
Error handling was cleaned up, but not much tested.
