Enhancements in EasyBuild v5.0¶
(for a full overview of changes in EasyBuild v5.0, see here)
Various significant enhancements are included in EasyBuild v5.0, including:
run_shell_cmd function¶
See dedicated page on the new run_shell_cmd function.
Granular exit codes¶
EasyBuild v5 now uses a range of ~50 exit codes instead of just 0 for normal termination and 1 for unexpected termination. Each non-zero exit code correlates to the specific type of error or failure that caused the termination of the program. For instance, a missing easyconfig or a failed checksum check. The full list of exit codes is defined in the class easybuild.tools.build_log.EasyBuildExit.
EasyBuild will always return its own exit codes on termination. Other exit
codes from external processes executed through run_shell_cmd or HTTP response
status codes are reported in the corresponding logs.
Reproducible tarballs¶
EasyBuild can now generate reproducible tarballs of sources cloned from Git
repositories. This means that those sources using the git_config option will
now have consistent contents across different systems and across time, allowing
to reliably validate them with checksums. EasyBuild follows the
archival guidelines from reproducible-builds.org
to generate those reproducible tarballs.
This new feature does not apply to sources cloned with keep_git_dir enabled.
Including the .git folder in the sources is inherently time-dependent as it
contains information about the clone action itself, which hinders the creation
of a reproducible tarball.
