** Scenario 3. "Full-blown development".
This is scenario for the packages which need the lot of work downstream
(e.g. kernel).
Branches:
upstream
topic-A
topic-B
...
master
Tree layout:
foo/ (in upstream, patched in topic-*, master)
.gear/rules (in master)
foos.pec (in master)
1. Importing the source to the upstream branch
As in previous scenarios.
2. Working on package.
All the work is done in topic branches, each is dedicated for some topic:
$ git checkout topic-A
$ vim ... # hack-hack-hack
$ git commit
$ git checkout topic-B
...
As patches may overlap, some conflict resolution need to be
involved. The naive approach would be using the following branching
scheme:
* upstream
|
\--> topic-A
\--> topic-B
\--> master
And then generating patch-per-topic by using .gear/rules. This will not
work, as the generated patches will conflict.
Instead, the following scheme is used:
* upstream
\-> topic-A
\-> topic-B
\-> master
And gear-merge(1) utility merges the branches as described in
.gear/merge file:
merge: upstream topic-A
merge: topic-A topic-B
merge: topic-B master
After using this utility (and resolving all conflicts occured), master
branch gets a cumulative change.
3. .gear/rules
The .gear/rules file will be exactly the same as for previous scenario,
so the gear-update-tag(1) is also reuired:
tar: v...@version@:foo
diff: diff: v...@version@:foo foo
4. Build
$ gear-rpm/gear-hsh (as in previous scenario).
5. Rebasing to new upstream version
$ ... # obtain the new upstream code in upstream branch
$ gear-merge
... Fix conflicts, update changelog, remove unnecessary patches etc...
$ gear-commit
Due to gear-merge, it's only necessary to fix the conflicts once.
6. New package revision
$ vim ... # hack-hack, commit
$ gear-merge
