Re: file handle limitation of 255

in reply to file handle limitation of 255

The limit on the number of open file handles is the kind of thing that would traditionally force programmers to be creative in finding algorithms that scaled nicely despite the limit.

For example, if you store your output in an accumulating data structure instead of hundreds of files that are being kept open, and modularize the process of adding content to the data structure, there's just a little extra planning work to be done to establish a threshold for when data needs to be dumped to a given file so that the given chunk of memory can be reused. It's a matter of striking a balance between the amount of memory consumed and the number of times files must be opened and closed.

    THANKS AGAIN!!! Yes, there are ways to overcome this, by working around this dis-advantage. But first, you have to realize that this is an issue :)

[Corion]: Last day at $work before 3 weeks of vacation (well, not that I'd be really travelling, but no-work-time ;) )
[robby_dobby]: marto: yeah, I'd eventually visit Glasgow some day - just to visit the home town of GHC :-)
[robby_dobby]: Corion: Oh, that's awesome! Your timing is perfect enough to see all hell break loose when you get back at work :P
[marto]: well, let me know in advance, I'll buy you a pint :)
[Corion]: robby_dobby: No, I'm returning in the second workweek of January. The main hectic parts are in the first days after the start of the new year
[robby_dobby]: marto: and, I'm not sure I'd be around here long enough for YAPC::EU
[marto]: Corion nice, what are you plans for Christmas?
[robby_dobby]: Corion: Nice, you just won't be around to deal with the mess - enjoy your vacation :-)
[robby_dobby]: marto: Sure, will do. Thanks!
[Corion]: marto: No great plans - I'll meet with my sister, my brother and my mother, but that's all :)
