Busybox xz truncates files larger than 60M
« on: July 25, 2013, 08:15:26 AM »
A large file, say an eglibc-2.17 source tarball, is about 12M compressed, and about 120M when fully uncompressed. Uncompressing it with busybox xz results in a truncated file. Is this a Busybox issue, or is there some system parameter that limits this?

If you have enough free space, please test busybox git, and if it still happens, report to busybox.

edit: The kernel tarball unpacks fine, it's 66mb compressed and 471mb uncompressed.

Your filesystem is in RAM, so unless you are uncompressing to mounted persistent storage, you may just be running out of RAM.

What are your sizes of RAM and of swapspace?

It's a VM with a gig of RAM, no swap. 8 gig HD. Linux source unxz | untar worked OK, now that you mention it. xzcat eglibc-2.17 | tar xv gives a "tar: short read". Slackware unxz's the file OK, using the non-busybox xz. Something about the way the file was compressed?

Did you try xz from the repo on the same file in the same system?

Maybe it was an "available memory" thing, because I can't reproduce it now.
