Streaming decompression #18

Open sgkasselau opened 10 years ago

sgkasselau commented 10 years ago

Hi,

I was wondering if streaming decompression is currently possible with pcompress?

Commands like:

pcompress -dp < inputfile.tar.pz > output.tar pcompress -dp < inputfile.tar.pz | tar xpf - pcompress -dp < inputfile.tar.pz | sha256sum -

currently cause pcompress to segmentation fault, as do attempts to use Bash's process substitution to decompress archives without the -p option e.g.

pcompress -d inputfile.tar.pz >(tar xpf -) pcompress -d inputfile.tar.pz >(sha256sum -)

This occurs with pcompress built on Ubuntu 10.04 and 13.04 from the latest commit 2702544d3f08132eeb481032df00728f3c429fe5, as well as a slightly earlier commit, f8d3ddfe397ebf29e4f608247204b686568d4d01

Archives decompressed as usual/typical with a non-existent file as the target output file e.g.

pcompress -d inputfile.tar.pz inputfile.tar

work as expected with these versions of pcompress, as does initial compression, streamed or otherwise.

Thank you in advance for your time and effort at looking at this issue.
