[PATCH 1/7] classes/license: fix handling of symlinks pointed to in LIC_FILES_CHKSUM

[Paul Eggleton]

If you set LIC_FILES_CHKSUM to point to a relative symlink then you'll
get "Could not copy license file" warnings in copy_license_files() since
the symlink won't be valid after it's copied. If the source is a symlink
then we need to dereference it first.

I encountered this when I used recipetool on the sources for capnproto,
where the c++ directory contains a LICENSE.txt symlink to the LICENSE
file in the parent directory, and this symlink ends up being pointed to
in LIC_FILES_CHKSUM.

[PATCH 2/7] devtool: add: show recipetool create output

[Paul Eggleton]

When running devtool add, instead of hiding the recipetool create
output, change it so that it's appropriate to show in the devtool
context and show it in real-time. This means that you get status output
such as when a URL is being fetched (though currently no progress
information.) recipetool create now has a hidden --devtool option to
enable this display mode.

[PATCH 3/7] devtool: finish: fix error if destination layer is not in bblayers.conf

[Paul Eggleton]

If devtool finish is run on a recipe where the recipe file itself is in
the workspace (e.g. where devtool add / devtool upgrade has been used)
and the specified destination layer is not in bblayers.conf, then we
need to avoid running bitbake -c clean at the end because the recipe has
been moved, but the bbappend is still present in the workspace layer at
that point and so if we do it will fail due to the dangling bbappend.
It's difficult to do the clean at the point we'd want to because tinfoil
is holding bitbake.lock for most of the time, but in any case cleaning
the recipe is less important than it used to be since we started
managing the sysroot contents more strictly, so just disable cleaning
under these circumstances to avoid the problem.

Fixes [YOCTO #10484].

[PATCH 4/7] devtool: finish: warn if moving recipe to unconfigured destination layer

[Paul Eggleton]

If you run devtool finish to move a recipe created in the workspace by
devtool add or devtool upgrade to a layer, and that layer is not
currently included in bblayers.conf (perhaps unintentionally), then the
recipe will no longer be visible to bitbake. In this scenario, show a
warning so that the user isn't surprised by the recipe "going missing".

[PATCH 5/7] recipetool: create: separate LICENSE items with & by default

[Paul Eggleton]

recipetool sets the LICENSE value based on licenses detected from the
source tree. If there are multiple licenses then they were being
separated by spaces, but this isn't actually legal formatting and if
you're using "devtool add" you get a warning printed when devtool
parses the recipe internally.

Earlier I had made a conscious decision to do it this way since it's up
to the user to figure out whether the multiple licenses should all apply
(in which case they'd be separated with &) or if there is a choice of
license (in which case | is the correct separator). However, I've come
to the conclusion that we can just default to & and then the ugly
warning goes away, and it's the safest alternative of the two (and most
likely to be correct, since it's more common to have a codebase which is
made up of code with different licenses, i.e. all of them apply to the
combined work).

I've tweaked the comment that we add to the recipe to explicitly state
that we've used & and that the user needs to change that if that's not
accurate.

Fixes [YOCTO #10413].

[Paul Eggleton]

If a variable is being set in the recipe when we've explicitly passed
None as the value to _test_recipe_contents() indicating that it
shouldn't be set at all, then we should be printing out the variable
name in the assertion message but it seems like I forgot to do a
substitution. Also include the value for informational purposes.

[PATCH 7/7] devtool: add "rename" subcommand

[Paul Eggleton]

When you run devtool add on a source tree we attempt to figure out the
correct name and version for the recipe. However, despite our best
efforts, sometimes the name and/or version we come up with isn't
correct, and the only way to remedy that up until now was to reset the
recipe, delete the source tree and start again, specifying the name this
time. To avoid this slightly painful procedure, add a "rename"
subcommand that lets you rename the recipe and/or change the version.

Hi Khem,

Why wouldn't it be?

Cheers,

Was thinking out loud if the path is expanded to absolute paths then
does it get recorded into task checksums  ?
