bitbake: lib/bb/utils.py: Do not preserve TERM in the environment

2020-06-16T22:34:45+00:00

The value of TERM is leaking into OE-Core postinst-useradd-${PN} scripts, which in turn can optionally be monitored by buildhistory. Prune the value in order to make the OE-Core buildhistory output more deterministic. (Bitbake rev: 0d5cdd0c0d65f2f81c3af0f3767fee86c4142c3a) Signed-off-by: Jacob Kroon Signed-off-by: Richard Purdie

bitbake: lib/bb/utils.py: Preserve ownership of symlink

2020-02-22T23:57:26+00:00

Yocto Bug: https://bugzilla.yoctoproject.org/show_bug.cgi?id=13806 Uncomment lchown() to preserve ownership of symlink. (Bitbake rev: 6a0b6dd17c6d842960d448114b252e92c55dea33) Signed-off-by: Daisuke Yamane Signed-off-by: Richard Purdie

bitbake: utils: add is_semver function

2020-01-27T16:48:10+00:00

This function checks if a string is a semantic version: https://semver.org/spec/v2.0.0.html The npm fetcher needs this function to validate its version parameter. (Bitbake rev: 61ac4e825fa7afbb76282030586abc9ee4ac215c) Signed-off-by: Jean-Marie LEMETAYER Signed-off-by: Richard Purdie

bitbake: utils: add sha384_file and sha512_file functions

2020-01-27T16:48:10+00:00

The npm fetcher needs these functions to support the subresource integrity: https://www.w3.org/TR/SRI/ (Bitbake rev: 80e2216e2b41cb6170292009064864449bc48bbe) Signed-off-by: Jean-Marie LEMETAYER Signed-off-by: Richard Purdie

bitbake: bb.utils: add get_referenced_vars

2020-01-19T13:31:05+00:00

Given a start expression, bb.utils.get_referenced_vars returns the referenced variable names in a quasi-BFS order (variables within the same level are ordered aribitrarily). For example, given an empty data store: bb.utils.get_referenced_vars("${A} ${B} ${d.getVar('C')}", d) returns either ["A", "B", "C"], ["A", "C", "B"], or another permutation. If we then set A = "${F} ${G}", then the same call will return a permutation of [A, B, C] concatenated with a permutation of [F, G]. This method is like a version of d.expandWithRefs().references that gives some insight into the depth of variable references.

bitbake: lib: remove unused imports

2020-01-19T13:31:05+00:00

removed unused imports which made the code harder to read, and slightly but less efficient (Bitbake rev: 4367692a932ac135c5aa4f9f2a4e4f0150f76697) Signed-off-by: Frazer Clews Signed-off-by: Richard Purdie

bitbake: bb.utils.fileslocked: don't leak files if yield throws

2019-12-16T23:27:14+00:00

Discovered with a recipe under devtool. The ${S}/singletask.lock file (added by externalsrc.bbclass) was leaked, giving a warning like: WARNING: +git999-r0 do_populate_lic: /home/laplante/yocto/sources/poky/bitbake/lib/bb/build.py:582: ResourceWarning: unclosed file <_io.TextIOWrapper name='/home/laplante/yocto/build/workspace/sources//singletask.lock' mode='a+' encoding='UTF-8'> exec_func(task, localdata) (Bitbake rev: 6beddf6214e22b4002626761031a9e9d34fb04db) Signed-off-by: Chris Laplante Signed-off-by: Richard Purdie

bitbake: utils: also use mmap for SHA256 and SHA1, for performance

2019-11-21T23:09:03+00:00

md5_file() uses a mmap() window to improve performance when hashing files, so refactor the code and do the same for SHA1 and SHA256. (Bitbake rev: ecf87437ff796e17c3e4f210b5803b0136a9e8a4) Signed-off-by: Ross Burton Signed-off-by: Richard Purdie

bitbake: utils: Add ionice option to prunedir

2019-09-19T19:30:35+00:00

Autobuilder type infrastructure can benefit from deletion of certain files as background IO due to the way Linux filesystem priority works. We have problems where build directories as part of oe-selftest being delete starves the running tasks of IO to the point builds take much longer to compelte. Having this option of running the deletion at "idle" helps a lot with that. (Bitbake rev: 797354d285f6d624d9adb52bab65823572da0e39) Signed-off-by: Richard Purdie
