Re: Re: CGI counter resets for no obvious reason

I never lock counter files and it always works fine, so I don't thinks it's neccessary.. *boggle*

Personally, I never lock my house door and my stuff is always there when I get back so I don't think doors are necessary.

Updated I didn't intend this to be mean but seriously, people haven't invented multiple ways to file lock just out of sheer boredom or for the excitement of it.

Yea, file locking is very important nomatter how unimportant you think it is. I made a really simple counter a couple weeks ago and my friend and I tested it. As soon as we both accessed the counter at the same time the '1' went to a '2.46578837244004' or something like that. I think the counter was along the lines of: `$cfile="counter.txt"; open(COUNT,$cfile); $count=<COUNT>; $count++; close(COUNT); open(COUNT,">$cfile"); print COUNT $count; close(COUNT); print "content-type: text/html\n\n"; print $count;` [download] (pretty confusing at first glance, eh?) Notice that there is no flock in there or any type of locking. Here are some links you should check out. Simple locking File locking flock Fcntl Wanna be perl hacker.

okok, I correct myself: For my special purpose(s) filelocking wasn't necessary. Everybody who wants to write serious counter-applications (not just for fun) should lock his/her files and make backups every now and then.. octopus -- GED/CC d-- s:- a--- C++(+++) UL+++ P++++$ L++>++++ E--- W+++@ N o?
