I think we're now down to: sudo path issues (Ross is poking) ncurses-doc issue (assigned to JPEW) perl host compiler flags issue sysvinit missing group problem (assigned to Mingli Yu at present)
(thanks Alex for spotting the obvious I couldn't see with one of the perl issues!) I wanted to document some of the interesting quirks we've seen with reproducibile build failures in case anyone else runs into these kinds of issues. First is the "embedded git hash" problem where a source tree embeds the output of "git describe" or the hash from a git command, even though the source has come from an upstream tarball. These commands travel back up the directory structure and find the hash or description (e.g. 3.1M1-XXXX) for our own metadata (poky or OE- Core). These are consistent as long as the same revision of the metadata is built. As soon as there are new commits or a rebase, they change and trigger the reproducible builds failure. This means they usually pass for master-next and break on master. Second is setcap issues. A number of recipes look for setcap on the host system and then change behaviour depending on whether they find it. Some of our workers have it as part of their default install some don't. Some recipes fall back to suid bits if setcap isn't present too just to confuse things. Third is the weird group problem for sysvinit. In this case its because the do_package_write_ipk was running against do_package from sstate and that gave different output to a full build due to the differing sysroot contents (missing etc/group file). The reproducer is simple once you realise what is breaking: bitbake sysvinit bitbake sysvinit -c clean bitbake sysvinit -c package_write_ipk -f Were also seeing a smattering of more well known issues like hardcoded hosttool paths (/bin/mv vs /usr/bin/mv), dash vs bash, sorting issues in generated header/C files and some host variable infection problems.
