From: Mingli Yu <[email protected]> pigz, which stands for parallel implementation of gzip, is a fully functional replacement for gzip that exploits multiple processors and multiple cores to the hilt when compressing data.
do_package uses pigz to compress data to speed up the time if there is pigz available on the build server. But for some big package such as clang, there comes below error during do_package. gzip: stdout: Cannot allocate memory tar: TOPDIR/sstate-cache/20/80/sstate:clang:cortexa57-wrs-linux:10.0.1:r0:cortexa57:3:20808f8a746b00ec9470a81057c8595d878cfe8c565cfbcbbaa3ea870528ee34_package.tgz.QF5dss8M: Wrote only 8192 of 10240 bytes tar: Child returned status 1 tar: Error is not recoverable: exiting now So set the default pigz thread and the user also can customize the pigz thread such as via PIGZ = "-p 3" or PIGZ_pn-clang = "-p 3" for the individual package in local.conf to avoid eating so much memory.
