Values are coming out write but it would be nice if the history was the same as well. Values are coming out *right* but it would be nice if the history was the same as well. ;-) From RP during bug triage call: * enable/disable tracking in finalizeData (like parse_recipe_file) * implement as a Python context manager Fixed by this commit: tinfoil: Track data during finalizeData - bitbake - Bitbake Development tree https://git.openembedded.org/bitbake/commit/?id=228979b506f7d0e24c643440bcc7becf684da283 |
The variable history part of the output of "bitbake -e" (without recipe) for DISTRO_FEATURES is different from "bitbake-getvar DISTRO_FEATURES": Notably, getvar lacks the operation from utils.py: --- bb_e 2024-11-19 16:55:50.418258203 +0100 +++ getvar 2024-11-19 16:56:09.450228084 +0100 @@ -1,5 +1,5 @@ # -# $DISTRO_FEATURES [10 operations] +# $DISTRO_FEATURES [9 operations] # :remove <SNIP>/poky/build-master/conf/local.conf:323 # "ptest" # :append <SNIP>/poky/build-master/conf/local.conf:392 @@ -18,8 +18,6 @@ # [doc] "The features enabled for the distribution." # set? <SNIP>/poky/meta/conf/bitbake.conf:904 # "" -# append utils.py:132 [features_backfill] -# " pulseaudio gobject-introspection-data ldconfig" # pre-expansion value: # "${DISTRO_FEATURES_DEFAULT} ${POKY_DEFAULT_DISTRO_FEATURES} seccomp polkit pam sysvinit pulseaudio gobject-introspection-data ldconfig" DISTRO_FEATURES="acl alsa bluetooth debuginfod ext2 ipv4 ipv6 pcmcia usbgadget usbhost wifi xattr nfs zeroconf pci 3g nfc x11 vfat seccomp opengl multiarch wayland vulkan seccomp polkit pam sysvinit pulseaudio gobject-introspection-data ldconfig" Richard saw this bug [0] while reviewing the fix of [1]: > If you read bitbake-cookerdaemon.log for "bitbake-getvar -r bash" you > will see disableDataTracking() call before finalizeData().

NB: From when Richard saw this bug, it moved to the "no recipe is specified" case and I can't see it anymore in bitbake-cookerdaemon.log but the difference in output is there.
