When importing the components during the "combo-layer init" with full
history and relocation into a destination directory, components with
empty commits were not handled because the "mv" command was invoked
with just one parameter.
Replacing that with a find/xargs pair avoids the problem and should
also fix the handling of filenames with special characters (in
particular spaces).

I ran into an issue where a patch just deleting a single file
within the repository (meta/recipes-devtools/m4/m4/make.patch)
would get skipped by combo-layer.
It turns out this has the patch header (commented to avoid breaking scripts):
: diff --git a/meta/recipes-devtools/m4/m4/make.patch b/meta/recipes-devtools/m4/m4/make.patch
: deleted file mode 100644
: index 79fb415..0000000
: --- a/meta/recipes-devtools/m4/m4/make.patch
: +++ /dev/null
: @@ -1,42 +0,0 @@
and this is classed as > 5 headers in filterdiff. When we piped the path
through filterdiff, the --- line disappears, then the second time we pass
through filterdiff, it shows no lines changed and the patch is assumed
to be empty and skipped.
Changing MAX_HEADERS in filterdiff is one way to fix this, another would
be to grep out "deleted file mode" lines. Instead, we can use new
git syntax to exclude files from the git format-patch instead and avoid
filterdiff entirely.

There is no ability at the moment for situations where users would like
to keep section in combo-layer.conf but don't update it, unless explicitly
specified.
Now, by adding "update = no" to desired section would exclude
that repository from "combo-layer update" command.
It is still possible to explicitly update it by "combo-layer update $section".
By default, all repositories are assumed as "update = yes"

When reconfiguring the branch to something not already fetched,
action_pull fails with
error: pathspec '<new branch name>' did not match any file(s) known to git.
It is the "git checkout" which fails like that. To solve this,
try the faster "git checkout + git pull" first and only if that fails,
fall back to the slow "git fetch + git checkout".
In the conf.hard_reset case, do the checkout always after the git fetch.

The git operations can fail, for example when the branch is unknown
or misconfigured.
Better move the info message and extend it such that it is printed
first and provides the necessary context, because otherwise the
CalledProcessError exception gets dumped without mentioning for which

Only allow fast-forward merges in the component repositories when doing
git-pull. This makes it possible to spot problems (i.e. rewriting of
history) in the component upstream . Also, this change prevents the
creation of local-only merge commits in the component repositories.
These merges cause "last_revision" field of the combo-layer config to
point to a git commit that is only present in the users local component
repository but nowhere in upstream.

This patch includes support for a global section in combo-layer.conf
called [combo-layer-settings]. Supported in this section is key
"commit_msg"; its value is the template for the git commit message
that updates the last_revision. The template can include substitution
for the updated component list: ${components}. The substituted value
will either be a comma-separated list of components or "all components",
if combo-layer was invoked without component list argument.
If the key is not present, the old default value is used for the commit
message.
Configuration file example:
[combo-layer-settings]
commit_msg = pulled in the latest changes for ${components}.

The previous "clean up dest_dir checking" patch (f8cdbe7497) improved
handling of empty dest_dir but made handling of unset dest_dir worse:
instead showing the "Option dest_dir is not defined for component ..."
error, it fails with a Python exception.
Avoid that by providing a sane fallback for the unset case. With that
change, dest_dir is no longer strictly required, but the check for it
is kept to ensure that a combo-layer.conf also works with older
combo-layer versions.

When the head of a branch is a merge commit, combo-layer did not
record that commit as last_revision because it only considers applied
patches, and the merge commit never gets applied.
This causes problems when the merge commit leads to multiple patches
and the commit id that gets recorded only reaches some of these
patches. The next run then will try to re-apply the other patches.
This special case is now detected and dealt with by bumping
last_revision to the branch commit. The behavior where the head is a
normal commit is intentionally not changed, because some users might
prefer the traditional behavior.

"filterdiff -x ./some/file" does not remove changes for some/file.
We must be more careful about constructing the path name and
only add the prefix when it really means a directory.
While at it, also better normalize the path in copy_selected_files()
early on, to handle double slashes. Useful should the function ever
gets used for something other that dest_dir (which gets normalized in
sanity_check()).

Empty dest_dir is basically undocumented behavior. The sample conf
only mentions using just a dot for the current directory. In practice,
the empty string does not work because of code like this:
def action_splitpatch(conf, args):
...
if dest_dir != ".":
filerange_root = '%s -x "%s/*"' % (filerange_root, dest_dir)
However, the empty string was not explicitly checked for, leading to
strange errors when trying to apply patches:
[12:50:23] Applying: foobar: xyz
fatal: unable to stat newly created file '/foobar': No such file or directory
This patch turns the empty string into an alias for the dot. This seems
more user-friendly than throwing an error. This alias is intentionally
not document in the sample conf, because the dot is clearer and works also
with older copies of combo-layer.
Instead of checking for both all the time and normalizing the path when
needed (as done in some places), rewrite the value in sanity_check()
and then only check for '.'.

The new "since_revision" property can be used to cut off the imported
history at some point. This is useful to keep the resulting repository
smaller while still preserving enough history that "git annotate"
reports the right author and commit for most lines.
The initial, squashed import commit shows up with "unknown" as author
in the "git annotate" output. It has the repository name as prefix
in the subject line; importing that commit works best with a
layer hook which does not add the repository name again when
it is already present. Adding it here is useful for hooks
which do not extend the subject line.

Instead of local graft entries rooting the imported branches in the
shared root commit, use replacement objects.
The advantage is that they get moved around by "git push" and "git
fetch", so everyone has the same, nicer view with everything starting
at the beginning of the combined repository.
If undesired, these objects can be removed with "git replace".

The new --history parameter enables a new mode in "combo-layer init"
where it copies the entire history of the components into the new
combined repository. This also imports merge commits.
Moving into a destination directory and applying commit hooks
is done via "git filter-branch" of the upstream branch. File
filtering uses the same code as before and just applies it
to that filtered branch to create the final commit which
then gets merged into the master branch of the new repository.
When multiple components are involved, they all get merged
into a single commit with an octopus merge. This depends
on a common ancestor, which is grafted onto the filtered
branches via .git/info/grafts.
These grafts are currently left in place. However, they do not get
pushed, so the local view on the entire history (all branches rooted
in the initial, empty commit, temporarily diverging and then
converging) is not the same as what others will see (branches starting
independently and converging). Perhaps "git replace" should be used
instead.
The final commit needs to be done manually, as before. A commit
message with some tracking information is ready for use as-is. This
information should be sufficient to implement also "combo-layer
update" using this approach, if desired. The advantage would be that
merge commits with conflict resolution would not longer break
the update.

Some combined repos intentionally do not include certain files.
For example, Poky does not include bitbake's setup files and
OE-core's sample files under meta/conf.
When these files get modified in the upstream repository, applying the
patches fails and requires manual intervention. That is merely a
nuisance for someone familiar with the problem, but a real show
stopper when having the import run automatically or by someone less
experienced.
Therefore this change introduces "file_exclude", a new per-repo list
of file patterns which removes all matching files when initializing or
updating a combined repository. Because fnmatch is used under the hood
to match full path strings, removing entire directories must be done
with a pattern ending in a '/*' (in contrast to file_filter).
For Poky, the additional configuration looks like this:
[bitbake]
...
file_exclude = classes/base.bbclass
conf/bitbake.conf
.gitignore
MANIFEST.in
setup.py
TODO
[openembedded-core]
...
file_exclude = meta/conf/bblayers.conf.sample
meta/conf/local.conf.sample
meta/conf/local.conf.sample.extended
meta/conf/site.conf.sample

Allow the caller to specify a separate output stream. stderr is always
a temporary file opened by runcmd(), so read from that to capture
output for error reporting *and* the return value.
The reasoning for the latter is a) that this preserves the traditional
behavior when out=None and b) if the caller wants the content of
stdout, it can read from the stream itself, which is not possible for
the temporary stderr.

It depends on the diligence of the person running the combo-layer tool
whether the Signed-off-by line added to each commit actually indicates
that the person was involved in validating the change.
When the import is purely automatic, it is better to not add the line,
because the history is more useful without it (searching for the person
really only lists changes he or she was involved with) and it would
be a false statement.
The 'signoff' property can be set per repository, like every
other property. But setting it in the special [DEFAULT] section
is more useful, so that is what the example shows.

When updating a property (at the moment, only 'last_revision'),
first check whether the user already added it to the main config.
If so, update there even if there is a local config.
This way, 'last_revision' can be shared between developers
as part of the repository while still configuring per-developer
repo paths outside of the git repository in a local config.
An example of a repository which is set up like that is tizen-distro,

Allow splitting the local parts of the configuration (mostly
local_repo_dir and last_revision, although there is no limitation) to
a side-by-side -local.conf file, with component sections optionally
tagged with the combo layer branch name. This effectively allows you to:
* avoid polluting the history by committing the updated last revision
to the combo repository for every update
* avoid putting local repo paths into the combo repository
* manage multiple branches of the combo repository whilst avoiding the
possibility of mixing the configuration for one branch with another.
