- 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.
