I think using a semicolon to separate items in IMAGE_EXTRA_PARTITION_DIRECTORIES could be confusing, as it’s already used for tuples in the IMAGE_EXTRA_PARTITION_FILES variable. A space-delimited list might be more intuitive and consistent with how IMAGE_EXTRA_PARTITION_FILES is structured. For example: IMAGE_EXTRA_PARTITION_DIRECTORIES_label-foo = "/test1 /test2/test3 /test4" IMAGE_EXTRA_PARTITION_FILES_label-foo = "bar1.conf;foo1.conf bar2.conf bar3;foo3" What do you think ? > > Signed-off-by: Adam Duskett <[email protected]> > --- > meta/lib/oeqa/selftest/cases/wic.py | 11 ++++++ > .../lib/wic/plugins/source/extra_partition.py | 38 +++++++++++++++++++ > 2 files changed, 49 insertions(+) > > diff --git a/meta/lib/oeqa/selftest/cases/wic.py > b/meta/lib/oeqa/selftest/cases/wic.py > index 33a6460677..d365345554 100644 > --- a/meta/lib/oeqa/selftest/cases/wic.py > +++ b/meta/lib/oeqa/selftest/cases/wic.py > @@ -1657,10 +1657,14 @@ INITRAMFS_IMAGE = "core-image-initramfs-boot" > def test_extra_partition_plugin(self): > """Test extra partition plugin""" > config = dedent("""\ > + IMAGE_EXTRA_PARTITION_DIRECTORIES_label-foo = "/test1;/test2/test3" > + > IMAGE_EXTRA_PARTITION_DIRECTORIES_uuid-e7d0824e-cda3-4bed-9f54-9ef5312d105d > = "/test1;/test2/test3" > IMAGE_EXTRA_PARTITION_FILES_label-foo = "bar.conf;foo.conf" > IMAGE_EXTRA_PARTITION_FILES_uuid-e7d0824e-cda3-4bed-9f54-9ef5312d105d = > "bar.conf;foobar.conf" > IMAGE_EXTRA_PARTITION_FILES = "foo/*" > WICVARS:append = "\ > + IMAGE_EXTRA_PARTITION_DIRECTORIES_label-foo \ > + > IMAGE_EXTRA_PARTITION_DIRECTORIES_uuid-e7d0824e-cda3-4bed-9f54-9ef5312d105d > \ > IMAGE_EXTRA_PARTITION_FILES_label-foo \ > IMAGE_EXTRA_PARTITION_FILES_uuid-e7d0824e-cda3-4bed-9f54-9ef5312d105d \ > " > @@ -1692,6 +1696,13 @@ INITRAMFS_IMAGE = "core-image-initramfs-boot" > result = runCmd("wic ls %s | wc -l" % wicimg) > self.assertEqual('4', result.output, msg="Expect 3 partitions, not %s" % > result.output) > > + for part, extra_dir in enumerate(["test1", "test2"]): > + result = runCmd("wic ls %s:%d | grep -q \"%s\"" % (wicimg, part + 1, > extra_dir)) > + self.assertEqual(0, result.status, msg="Directory '%s' not found in the > partition #%d" % (extra_dir, part)) > + > + result = runCmd("wic ls %s:%d/test2 | grep -q \"test3\"" % (wicimg, part > + 1)) > + self.assertEqual(0, result.status, msg="Directory test2/test3 not found > in the partition #%d" % part) > + > for part, file in enumerate(["foo.conf", "foobar.conf", "bar.conf"]): > result = runCmd("wic ls %s:%d | grep -q \"%s\"" % (wicimg, part + 1, > file)) > self.assertEqual(0, result.status, msg="File '%s' not found in the > partition #%d" % (file, part)) > diff --git a/scripts/lib/wic/plugins/source/extra_partition.py > b/scripts/lib/wic/plugins/source/extra_partition.py > index 3abd2bfd4c..fee72df615 100644 > --- a/scripts/lib/wic/plugins/source/extra_partition.py > +++ b/scripts/lib/wic/plugins/source/extra_partition.py > @@ -20,13 +20,19 @@ class ExtraPartitionPlugin(SourcePlugin): > - File renaming. > - Suffixes to specify the target partition (by label, UUID, or partname), > enabling multiple extra partitions to coexist. > + - Extra directories. > > For example: > > + IMAGE_EXTRA_PARTITION_DIRECTORIES_label-foo = "/foo;/bar/baz" > + > IMAGE_EXTRA_PARTITION_DIRECTORIES_uuid-e7d0824e-cda3-4bed-9f54-9ef5312d105d > = "/foo;/bar/baz" > + > IMAGE_EXTRA_PARTITION_FILES_label-foo = "bar.conf;foo.conf" > IMAGE_EXTRA_PARTITION_FILES_uuid-e7d0824e-cda3-4bed-9f54-9ef5312d105d = > "bar.conf;foobar.conf" > IMAGE_EXTRA_PARTITION_FILES = "foo/*" > WICVARS:append = "\ > + IMAGE_EXTRA_PARTITION_DIRECTORIES_label-foo \ > + > IMAGE_EXTRA_PARTITION_DIRECTORIES_uuid-e7d0824e-cda3-4bed-9f54-9ef5312d105d > \ > IMAGE_EXTRA_PARTITION_FILES_label-foo \ > IMAGE_EXTRA_PARTITION_FILES_uuid-e7d0824e-cda3-4bed-9f54-9ef5312d105d \ > " > @@ -35,6 +41,7 @@ class ExtraPartitionPlugin(SourcePlugin): > > name = 'extra_partition' > image_extra_partition_files_var_name = 'IMAGE_EXTRA_PARTITION_FILES' > + image_extra_partition_dirs_var_name = > 'IMAGE_EXTRA_PARTITION_DIRECTORIES' > > @classmethod > def _get_extra_vars(cls, part, var_name): > @@ -50,6 +57,30 @@ class ExtraPartitionPlugin(SourcePlugin): > break > return extra_vars > > + > + @classmethod > + def _parse_extra_directories(cls, part): > + """ > + Parse the directories of which to copy. > + """ > + cls.extra_dirs_task = [] > + > + extra_dirs = cls._get_extra_vars(part, > cls.image_extra_partition_dirs_var_name) > + if extra_dirs is None: > + logger.debug('No extra directories defined, %s unset for entry #%d' % > (cls.image_extra_partition_dirs_var_name, part.lineno)) > + return > + > + logger.info('Extra dirs: %s', extra_dirs) > + for src_entry in re.findall(r'[\w;\-./*]+', extra_dirs): > + if ';' in src_entry: > + dst_entries = src_entry.split(';') > + if not dst_entries[0] or not dst_entries[1]: > + raise WicError('Malformed extra dir entry: %s' % src_entry) This raises an error for " foo;", but not for " foo;bar; ".

For example to prepare a data partition with only directories. However, since extra partition plugin was not designed to create empty partitions (omitting --source achieve this), I think the plugin should raise an error if no files or directories are defined.
