The intent of this limit is to stop a runaway process eating all of RAM and swap. It is probably reasonable as a default for a workstation (X, KDE, Mozilla & OpenOffice are each unlikely to exceed 512MB during normal use) or server. People with atypical requirements will need to do some tuning. I agree that the defaults mean you can't run 'ls' on a directory with 2e6 files but this isn't a typical requirement. Upping the default limit to 1GB increases the risk that a runaway process will make the machine unusable (think how your machine with 768MB RAM would behave if you increased datasize to 1GB and tried to run ls on a directory with just under 4e6 files). As for ls(1), its theoretical memory requirements are of the order of 32 bytes per entry plus the size of the directory in order to run 'ls -lsio'. It should be reasonably easy to remove the need to store anything if you don't require sorting or column alignment but beyond that, the code complexity starts to increase significantly. -- Peter JeremyReceived on Fri Apr 23 2004 - 15:12:52 UTC
