devtool: improve git repo checks before check_commits logic

2019-01-22T14:35:58+00:00

The check_commits logic assumes that both devtool-base and args.branch exist in the git repo that it is operating on. In order to prevent errors at that point it's best to first ensure that both of these refs actually exist. If they don't both exist then the check_commits logic should just be skipped, as it would be if the repo wasn't originally checked out by devtool. Previously if a user removed the args.branch branch from their devtool cloned repo this code would crash on adding the repo with -n. The crash would look like this: Traceback (most recent call last): File "/home/ddedrick/src/poky/scripts/devtool", line 344, in ret = main() File "/home/ddedrick/src/poky/scripts/devtool", line 331, in main ret = args.func(args, config, basepath, workspace) File "/home/ddedrick/src/poky/scripts/lib/devtool/standard.py", line 812, in modify (stdout, _) = bb.process.run('git log devtool-base..%s' % branch, cwd=srctree) File "/home/ddedrick/src/poky/bitbake/lib/bb/process.py", line 178, in run raise ExecutionError(cmd, pipe.returncode, stdout, stderr) bb.process.ExecutionError: Execution of 'git log devtool-base..devtool' failed with exit code 128: fatal: ambiguous argument 'devtool-base..devtool': unknown revision or path not in the working tree.

devtool: remove duplicate overrides

2019-01-22T14:35:58+00:00

DEVTOOL_EXTRA_OVERRIDES only needs one entry for each instance of overrides. Previous to these changes it would find every override to SRC_URI and add it to the list. This would duplicate instances where SRC_URI is modified multiple times with the same override like: SRC_URI_append_foo += "file://0001-foo.patch" SRC_URI_append_foo += "file://0002-bar.patch" A bbappend might also overwrite a SRC_URI override, which would also cause multiple instances to occur. When there are multiple instances of the same override in DEVTOOL_EXTRA_OVERRIDES it causes devtool modify to fail when creating override branches. The failure occurs when attempting to create the same override branch a second time and looks like this: The stack trace of python calls that resulted in this exception/failure was: File: 'exec_python_func() autogenerated', lineno: 2, function: 0001: *** 0002:devtool_post_patch(d) 0003: File: '/build/poky/meta/classes/devtool-source.bbclass', lineno: 202, function: devtool_post_patch 0198: 0199: for override in extra_override_list: 0200: localdata = bb.data.createCopy(d) 0201: if override in default_overrides: *** 0202: bb.process.run('git branch devtool-override-%s %s' % (override, devbranch), cwd=srcsubdir) 0203: else: 0204: # Reset back to the initial commit on a new branch 0205: bb.process.run('git checkout %s -b devtool-override-%s' % (initial_rev, override), cwd=srcsubdir) 0206: # Run do_patch function with the override applied File: '/build/poky/bitbake/lib/bb/process.py', lineno: 178, function: run 0174: if not stderr is None: 0175: stderr = stderr.decode("utf-8") 0176: 0177: if pipe.returncode != 0: *** 0178: raise ExecutionError(cmd, pipe.returncode, stdout, stderr) 0179: return stdout, stderr Exception: bb.process.ExecutionError: Execution of 'git branch devtool-override-foo devtool' failed with exit code 128: fatal: A branch named 'devtool-override-foo' already exists.

logging: use warning instead warn

The warn method is deprecated. We should use the documented warning instead.

devtool: add --force-patch-refresh to 'modify' and 'finish' commands

2018-03-11T13:27:00+00:00

This is very useful for updating patch context so that any fuzz is eliminated. Simply issue: devtool modify devtool finish --force-patch-refresh Without this flag, devtool will not deem the commits in the workspace different to patches in the layer, even if the commits have different, up-to-date context line in them.

devtool: finish: fix erroneously creating bbappend for relative paths

2018-03-01T22:13:56+00:00

After OE-Core rev 5e3fe00a0233d563781849a44f53885b4e924a9c we call os.path.abspath() on the original layer path, but we later compare that to the destination layer path. If that layer path isn't absolute but is effectively the same path, it should be writing to the original recipe but because we weren't making it absolute we were writing a bbappend instead. Call os.path.abspath() on the destination path as well to avoid that. (From OE-Core rev: a85a78dcf226d160e9b504bfa67b306a9175ac29) Signed-off-by: Paul Eggleton Signed-off-by: Richard Purdie

devtool: reset: delete bbappend file if _check_preserve() doesn't

2018-03-01T22:13:56+00:00

If the .devtool_md5 file doesn't contain a reference to the bbappend file (e.g. because devtool was interrupted before it could write that out) then _check_preserve() won't delete it, so we need to delete it separately because otherwise the recipe won't actually be reset.

devtool: fix poor handling of upgraded BBCLASSEXTENDed recipes

2018-03-01T22:13:56+00:00

Fix two aspects of handling BBCLASSEXTENDed targets (e.g. openssl-native) that have been run through "devtool upgrade": * Fix recipe name not showing up in "devtool status" * Fix "devtool reset" not deleting empty directories under the recipe directory within the workspace, which may lead to problems if you subsequently run "devtool upgrade" on the same target again (From OE-Core rev: 56e04260d64de9c5b83893d97cf41b7ea9a45878) Signed-off-by: Paul Eggleton Signed-off-by: Richard Purdie

devtool: implement conditional patch handling

2017-11-11T12:14:27+00:00

If you have a recipe that uses overrides to conditionally extend SRC_URI to add additional patches, then you will often need to update those patches if you're making other changes to the source tree (for example if you're upgrading the underlying source). Make this possible with devtool by creating devtool-override-* branches for each override that conditionally appends/prepends SRC_URI, and have devtool update-recipe / finish check each branch out in turn and update the corresponding patches. A current example of a recipe that does this is the quota recipe - it applies an additional patch if musl is the selected C library (i.e. libc-musl is in OVERRIDES). Note that use of this functionality does require some care - in particular, updates to patches that appear on the main branch (named "devtool" by default) should be made there and not only on one of the specific devtool-override-* branches that are created for each override. The recommended procedure is to make the changes you want to make to the main branch first, then check out and rebase each devtool-override-* branch, testing each one by activating the corresponding configuration, and then finally run devtool finish.

devtool: finish: add dry-run option

2017-11-11T12:14:27+00:00

If you're not sure what changes devtool finish is going to make, or you're not sure you're finished with your modifications, it is useful to be able to see what devtool finish is going to do beforehand, so add a -N/--dry-run option to make that possible. (It's also very useful for debugging devtool finish itself.)

devtool: finish: improve reporting for removed files

2017-11-11T12:14:27+00:00

If a file is going to be effectively removed from the destination by devtool finish, we should report that rather than just reporting that we're removing files from the workspace. This is a little tricky because the way we actually operate when finishing is to: (1) remove all original files (as recorded by devtool upgrade, if that was used) (2) as part of updating the recipe file, remove the files from next to the new recipe (i.e. in the workspace for an upgrade, real recipe otherwise) corresponding to commits not in the git tree (3) copy over remaining files from the workspace to the destination To report the files removed with respect to what was originally there, we need to swap steps 1 and 2 so we can see what no longer exists after the deletion, and suppress the reporting currently done in step 2 - however, we still want to report removal in step 2 for the non-upgrade case, so the latter is conditional.
