update-header would read lines from stdin consisting of the filename
and message classification, and modify each message in place. A short
perl version could look something like this:
#!/bin/perl
# update-header -- read file and msg type, add ifile header.
while (<>)
{
chomp;
($file, $type) = split;
# store entire message
open (F, "< $file") || die "can't read $file";
$_ = do { local $/; <F> };
close (F);
# find end of header
$nl = index ($_, "\n\n");
die "no blank line" if $nl < 0;
# write original header, msg type, and remainder
open (F, "> $file") || die "can't write $file";
print F substr($_, 0, $nl+1);
print F "X-Ifile-Result: $type\n";
print F substr($_, $nl+1);
close (F);
}
exit (0);
The goal is to avoid multiple runs of ifile. The amount of time ifile
spends on initialization and loading its wordlist should be fairly
constant, depending mostly on the size of .idata. We'll spend that
time whether we process one mail message or a thousand, so we may as
well handle as many messages as we can for any one run.
