[oe][OE-core][Patch 0/2] implement applying patches from a directory

[Max Krummenacher]

The current developer manual [1] specifies that patches that are
part of a directory which is given in SRC_URI are applied by
the do_patch task. However that is not implemented in the
current code.

This patchset implements that, but deviates from what is
documented. If the patches are applied I will send a patch
for the documentation changing the relevant part to:

```
If you have a directory full of patch files and you want to
apply them all you can add the directory to SRC_URI and add
the "apply=yes" parameter. This will apply ALL files in the
directiory, including files in subdirectories.
The patches will be applied sorted by their filename. Files
from subdirectories will be sorted into the list at the
position given by the subdirectory name.

   SRC_URI = " \
       git://path_to_repo/some_package \
       file://path_to_lots_of_patch_files;apply=yes \
       "

In the previous example all the files in the directory holding
the patch files would be applied as a patch.
```

[oe][OE-core][Patch 1/2] lib/oe/patch.py: apply patches from src_uri specified directories

[Max Krummenacher]

The current developer manual specifies that patches that are
part of a directory which is given in SRC_URI are applied by
the do_patch task. However that is not implemented in the
current code.

Implement part of it with two differences:
- The implementation requires the parameter "apply=yes" and
  adds all files as patches, not only files ending in .patch
  and .diff.
  This keeps recipes which depend on the current implementation
  working.
- The possibility to exclude a file in that directory from being
  applied by a follow up entry with "apply=no" is dropped.

This assumes that patches can be ordered (in here alphabetically) - 
which isn't the case for most of the projects I worked with - I think it 
was also a reason why one has to specify the order and inclusion in SRC_URI.

Wouldn't be a sorted glob be more suitable here?

This was immediately my concern as well when I read the 0/N for the series.

I'd be more inclined to remove the documentation, rather than trying
to deal with sorting and sequencing issues. Since it hasn't been
working until now, there wouldn't be any users to annoy with dropped
functionality.

(That being said, we could make the argument that anyone attempting to
just point at a directory full of patches knows enough that they need
to have them named in a way to keep them sorted and applied in order).

This now implemented feature is not meant to replace the current way
of specifying patches. So if you cannot change the patch filenames
to specify the order then don't use it.

One use case I envision is a patchset in flight while upstreaming to
the upstream project. Apply such a patchset as the content of a
directory. For that use case the patches are sorted with their
000x-*.patch naming from generating them by default.
If you want to mix apples and orange patches, then I agree that the
directory approach is probably the wrong one.

Well yes, that is obvious.  I can't imagine why anyone would want to
even use potentially unordered directories of patches, so making it
a replacement would be unwise :D

Agreed. If someone is dumping patches from git, they get numerical
ordering. Practice shows that even nicely ordered patches start to
get a strange ordering as more are added, some are removed (and
people forget to specify start-number when dumping the new patches).

I'm sure someone might use the functionality, and it is true that it has
no impact on the main workflows, so there's no risk there. It is just
more code to support (and we should probably have a test added for
it) .. and Richard probably knows better than me the risks and if it
will actually be used.

First, I'd very much welcome a patch for the documentation since I
assume if this gets merged it does not get backported, so currently
maintained but not master branches would have the old behavior,
warranting a fix in the documentation.

I would assume that this can break kernel-yocto and the KERNEL_FEATURES
with optional patching if .scc and .patch files are in the same
directory which is added to SRC_URI with apply=True.

On a slightly different topic, I personally think that including directories
in SRC_URI should be discouraged because overriding a directory from a
bbappend is completely replacing it and not doing a mergeof both
directories.

i.e.

some-dir/a
some-dir/b
some-dir/c

bbappend/some-dir/b

The result is the only file fetched by the recipe is b from the
bbappend. So it makes it much harder to override only one file from
within a directory which is included in SRC_URI.

Can I ask about the motivation here? Have you a use case you needed this to work
with or are you just making the code match the docs?

I'm a little worried about adding features like this which aren't commonly used
and clearly haven't been needed for a while. Such changes really do need some
kind of test case and as Bruce mentions, ordering of patches patches in
directories is a concern, you did at least sort the listdir() output which is
good :)

In the past when I've needed something like this, dumping "ls -1" into a file
and turning it into a SRC_URI hasn't been too hard even for long lists of
patches...

Cheers,

Richard

I want to do continuous integration / testing in our upstreaming efforts
to U-Boot/Kernel. So I would create a directory with any prerequisite
patchsets and our mainlining patchsets which are on the ML but not yet
in the repo and put the individual patches in the relevant directory.

Should any work on the repo break any of the patches automated testing
would then trigger us to rebase/change whatever needed.
With the directory approach would take away the burden of fiddling
with patch lists in SRC_URI.

I assume there already is a test for do_patch in the current automated
testing. I could integrate the recipe I used for testing this extension
of the patch functionality.

I used the "ls -1" approach in the past to make my life easier, I guess
however that the directory approach would simplify things even more.

Would a patchset with a test be acceptable?

But you can use externalsrc to simply point to a custom source checkout, no?
