Re: Storable, Cygwin, and memory issues

Of course few tens of megabytes should be processed okay.
I used to operate this way Archive::Zip object of size 35Mb, which was done for archive some 400Mbytes, in order to save archive creation time -- without any problems.

You didn't provided many detailed version information, so I guess on what I saw in your post.
As long as you mentioned "cygnus" I assume this cygwin is rather old, and it could be that its default mounts are text (as opposed to binary), so this could lead to broken numbers and thus huge memory allocations.

As for memory profiling - I use very primitive but quite handy way to see for memory consumptions. near 1Gb -- just ordinary task manager shows eaten memory just fine.
Otherwise Devel::Peek for precise analyzis, but this requires some programming.

BR,
Vadim.

Thanks for the reply. Yes, it is quite an old cygwin: 1.3.22, running perl 5.8.0 with Storable 2.04. The mount points are binmode. --Dave Opinions my own; statements of fact may be in error.	[reply]

... not the oldest cygwin ever :):) Did you succeeded narrowing down a problem to some reproducable test case? (sorry for being trivial:)	[reply]

Excellent suggestion: if there's no known problem then I'll see if I can do that. Do you have any ideas what direction to head in? Are then any types of data that Storable might have problems with (e.g. self-referential structures, blessed things, big hashes, big arrays, ...). A simple flat array of `[ (1) x 10e6 ]` doesn't seem to trigger it. --Dave Opinions my own; statements of fact may be in error.	[reply] [d/l]
