* bitbake-whatchanged: print what is about to happenRobert Yang2013-03-071-0/+339
* Contents: - Summary - Usage - Implementation summary - Output - TODO * Summary: This is used for printing what is about to happen between the current and last builds, for example: $ bitbake core-image-sato # Edit some recipes $ bitbake-whatchanged core-image-sato The changes will be printed. * Usage: bitbake-whatchanged [[opts] recipe] * Implementation summary: - Use the "STAMPS_DIR=<path> bitbake -S recipe" to generate the new stamps, compare these stamps to the one in the old stamps dir (tmp/stamps), so we will get what are changed. - When the "-v" (verbose) is not specified: > Figure out the newly added tasks > Figure out the PV (including PE) and PR changed tasks > The left tasks are the ones that the "Dependencies" changed tasks - When "-v" is specified: > Figure out the newly added tasks > Use bb.siggen.compare_sigfiles to figure out the details * Output, for example (core-image-sato with different git tags) and with recipes upgraded): - without "-v": Figuring out the STAMPS_DIR ... Generating the new stamps ... (need several minutes) === Newly added tasks: (5 tasks) core-image-sato: do_configure do_populate_lic do_install do_rootfs do_compile # Note: This is because the "bitbake -S" always generate the sigdata for # do_compile, do_rootfs and other task, we may need fix this from "bitbake -S" === PV changed: (130 tasks) alsa-utils: 1.0.25 -> 1.0.26 cross-localedef-native: 2.16 -> 2.17 eglibc-initial: 2.16 -> 2.17 [snip] === Dependencies changed: (3593 tasks) busybox: do_package do_package_write do_build do_packagedata do_populate_sysroot do_install do_compile do_package_write_rpm do_configure do_populate_lic atk-native: do_compile do_package_write_rpm do_package do_configure do_populate_sysroot do_install do_populate_lic do_patch do_packagedata do_build do_package_write do_unpack [snip] === Summary: (3728 changed, 1134 unchanged) Newly added: 5 PV changed: 130 PR changed: 0 Dependencies changed: 3593 Removing the newly generated stamps dir ... - with "-v": === Newly added tasks: (5 tasks) core-image-sato: do_configure do_populate_lic do_install do_rootfs do_compile === The verbose changes of glib-2.0-native.do_do_install: Hash for dependent task virtual:native:glib-2.0_2.34.3.bb.do_compile changed from bab8b8dd95be1b83dcec93f755b1812b to 70f746df7809acaa52de204b0685abb4 [snip] === Summary: (3728 changed, 1134 unchanged) Newly added: 5 Dependencies changed: 3723 Removing the newly generated stamps dir ... * TODO - It seems that the "bitbake -S core-image-sato" has bugs, it would always report errors, but doesn't fatal errors - The gcc-cross' stamps are in tmp/stamps/work-shared, but the "bitbake -S" doesn't put the stamps in work-shared. - The "bitbake -S" always generates the sigdata for image recipe's do_compile, do_install and other tasks, we may need fix this from "bitbake -S". - Print the ones which can be installed from the sstate.
