Since the list of files is sorted, it is possible to avoid quadratic
behaviour by implementing merge-like intersection.
However note that directory names are not sorted (this is why it is
needed to build full file name for strcmp).
Tested with gnome-icon-themes-oxygen-refit2-2.3-alt1.src.rpm,
3 subpackages each 13-16K files. Old behaviour: 18 seconds,
new behaviour: less than 1 second.
Some code (e.g. apt/genpkglist) explicitly relies on the fact that
header file list is represented with baseNames+dirNames+dirIndexes
arrays. Thus, generating legacy headers might have issues, and should
be disabled.
- implemented post-transaction filetriggers, loosely based on filetriggers.patch
from Mandriva Linux (see %_rpmlibdir/posttrans-filetriggers for details)
- implemented %_rpmlibdir/0ldconfig.filetrigger, so that packages with
shared libraries need not to invoke ldconfig(1) in they %%post-scriptlets

This fixes invalid cpio entries for `/dir/.*' constructs.
Consider this:
%install
install -pD /dev/null %buildroot/root/.bashrc
%files
/root/.*
Old behaviour:

The problem here is that glob(3) `dir/.*' globs both '.' and '..'.
It is not clear whether or not glob(3) should glob '.' and '..'.
$ bash -c 'echo /var/empty/.*'
/var/empty/. /var/empty/..
$ ksh -c 'echo /var/empty/.*'
/var/empty/.*

When I write e.g. 'Requires(pre): /usr/bin/perl' in specfile,
I get the following flags:
$ perl -le 'printf "%16b\n", 576'
1001000000
$
which is RPMSENSE_PREREQ|RPMSENSE_SCRIPT_PRE.
Before this change, I do not specify what flags were generated
for scriptlet dependencies. After this change, autogenerated
flags for %pre-script are:
$ perl -le 'printf "%16b\n", 16960'
100001001000000
$
which is RPMSENSE_PREREQ|RPMSENSE_SCRIPT_PRE|RPMSENSE_FIND_REQUIRES.
I belive it looks sane now.
PS:
alias rpmdump='perl -MData::Dumper -MRPM::Header -e "print Dumper(RPM::Header->new(@ARGV))"'
