in thread XML parsing

You have my sympathy. Since you are counting (or hoping) on the file format to not change, and not treating the data as XML (as suggested by your code above), you could improve it a little bit.

Assuming that you just want the number between the FILE_SIZE tags, you can do something like:

open my $fh, "<$ack_filename" or die "open error: $!"; my $file_size; while (<$fh>) { chomp; if (m|<file_size>([^<]*)</file_size>|i) { $file_size = $1; last; } } $fh->close; print $file_size;
This avoids running an external command and does not require the value to start at on offset of 13 in the second line from last. Even though it is more flexible, it would not be the right approach to parse XML data, but in your difficult situation I guess you can't do much better.

Then again, if the people you work with are so stupid and stubborn, maybe they deserve such code or worse.

Good luck getting out of there.

[erix]: easiest setup is to run with PG* env variables set, and a custom .pgpass files (can be a $PGPASSFILE)
[Corion]: Hmm - "trust" sounds interesting, but I have still to find whether I can restrict that on a per-DB level ;)
[Corion]: erix: Sure, but SQLite doesn't even need that :)
[hippo]: Corion: Yes, you can. It's all in the pg_hba.conf
[erix]: yeah, but there is a lot SQLite cannot do :)
[hippo]: Database is the 2nd column.
shmem .oO( docker. docker. docker? docker. docker! docker )
[shmem]: at least, some Ook.
[erix]: another simple Pg thing is to running a database off a tsv (alas, readonly)
