Bitbake does not record locations where the variables are changed. Fixing this would require an important change in Bitbake, which could severely impact the performance; setVar needs to record the backtrace of where it is called and save it in a var flag. Propose delay for 1.5.X moved to 1.5.1 I would propose modifying bitbake to keep track in a variable flag the current file:line of code where a variable is modified. Opinions ? When history tracking is turned on it definitely does record this information. You can see it in the bitbake -e output. I got this info on bitbake -e.
#
# $B_pn-xcb-util-image
# [no history recorded]
#
# "${SEPB}"
B_pn-xcb-util-image="/home/ddalex/ssd/yocto/build/tmp/work/x86_64-poky-linux/bblayers/1.0-r0/build"
#
# $localstatedir
# [no history recorded]
#
# "${base_prefix}/var"
export localstatedir="/var"
Am I doing something wrong ?
Something is going wrong there because my equivalent here is:
#
# $B_pn-xcb-util-image
# set /home/paul/poky/poky/meta/conf/distro/include/seperatebuilddir.inc:706
# "${SEPB}"
B_pn-xcb-util-image="/home/paul/poky/poky/build/tmp/work/i586-poky-linux/bblayers/1.0-r0/build"
#
# $localstatedir [2 operations]
# exported conf/bitbake.conf:31
# [export] "1"
# set conf/bitbake.conf:31
# "${base_prefix}/var"
# computed:
# "${base_prefix}/var"
export localstatedir="/var"
Fix merged in origin/master and origin/dora-toaster. The file field is deleted. There is a new table, orm_variablehistory, that tracks all changes for a variable. The REST API page have been modified to document the API change, but the patchset for the API change was not merged yet.
