Too many open files error while doing a mass forced upgrade

[snowflake (Dave Evans)]

I have 641 ports installed.

I deleted all the inactive ports.

I then ran a command to force upgrade them all with the +universal variant:

script bigbuild.log sudo port -pdk upgrade --force installed  +universal

After a few hours of compilation an error occurred:

./libtool: cannot make pipe for command substitution: Too many open files

I increased the ulimit(1) open files limit for the process from 256 to 10000 and ran the upgrade command again. While it was running I monitored the open files for the tclsh process using lsof:

I noticed that there were a lot of instances of

/opt/local/var/macports/receipts/file_map.db

open.

I counted them with:

sudo lsof | grep -i tcl | grep receipts | wc -l

and there were 272 instances of this file open.

I think there is an open file leak in port.

Fixed in trunk in r61770, merged to branch in r61771.

This happened to me just now when running the restore_ports.tcl script to reinstall my ports after some other problems.
