The following Perl script finds problems in your history files and fixes
them. THe comments indicate how to use.it. Use at your own risk.
#!/usr/local/bin/perl
#
# history database sanity checker
# David Barr <barr@math.psu.edu>
# version 1.1
# Throw away history entries with:
# malformed lines (too long, contain nulls or special characters)
#
# INN Usage:
# ctlinnd throttle 'fixing history'
# ./fixhist <history >history.n
# makehistory -r -s `wc -l <history` -f history.n
# mv history.n history
# mv history.n.dir history.dir
# mv history.n.pag history.pag
# ctlinnd go 'fixing history'
# any malformed entries will be output to stderr.
$MAXKEYLEN=255;
$now=time();
while (<>) {
chop;
($msgid,$dates,$arts,$xtra) = split('\t');
if ($xtra) {
&tossit(); # too many fields
next;
}
unless ($msgid) {
&tossit(); # too few fields (emtpy, usually)
next;
}
if (length($msgid) >= $MAXKEYLEN) {
&tossit(); # message-id too long
next;
}
if ($msgid !~ /^<[^< ]*>/) {
&tossit(); # malformed msg-ids
next;
}
if (/[\000-\010\012-\037\177-\377]/) { # non control-chars except tab
&tossit(); # illegal chars
next;
}
# if ($dates) {
# ($date_a,$date_e,$date_p)= split('~');
# $date_e=0 if ($date_e='-');
# $date_p=0 if ($date_p='-');
# }
# print "$_\n";
}
sub tossit {
print STDERR "$_\n";
