(What is the problem and what solution did we find?)
-The problem for the GNUnet community stated here is how to evolve the
-GNUnet team and code organization, so that developing code gets
-attractive again and using GNUnet for testing purposes or even for some
-little usecases becomes easier. In the current organizational model
-bugs tend to accumulate until they are not managable or overwhelming,
-however, it's clear, that every release candidate should be free from
-known bugs. There is more. Devs and user need to feel progress to have
-"Erfolgserlebnisse" (roughly: "sense of achievement") and recognition,
-like a new release, a "product" they have contributed to, listing new
-features with short description of amazing privacy preserving use cases.
-A possible solution to this problem might be a new and lightweighted
-release model with git.
-Release Models with git:
-Option 1:
- * code organization and branching
- * master branch is release branch, tagged with different version
- numbers development occurs in little side branches
- * mature code resides in a staging branch for testing and quality
- management
- * release process
- * development in little side branches
- * if code is mature, merge with staging branch and do testing,
- * static/dynamic analysis and code audits if checks are okay, merge
- with release branch and tag with new version number
-Option 2:
- * code organization and branching
- * master branch is development branch
- * further development task can be done in other side branches
- for every release candidate exists a new branch called after the
- version number
- * release process
- * development in master and side branches
- * if code of side branches is mature merge with master branch
- * if code in master branch is mature, create if not existant a new
- * release branch called after the new version number and merge with
- master
- * in the release branch do testing, static/dynamic analysis
- and code audits
- * if checks are okay, tag as release candidate
-Option 3: (What we really do right now)
-* changes that are not expected/known to break anything go into master;
- we may be wrong, better CI may allow us to detect breaking changes
- before merges in the future (but we shall never fault anybody for
- breaking stuff in master in non-obvious ways);
-* experimental development happens in branches, created by individuals
- or groups as they see fit. They are encouraged to merge often (if that
- would not break anything) to avoid divergence and to detect issues from
- a merge/rebase early.
+In the past it was sometimes unclear when and how the community would reach its
+next release. Members were lacking in orientation and felt demotivated.
+Another minor concern not yet analysed in depth was the expectation to show the
+public that the GNUnet project is still active and making progress. With an old
+release distributed by popular linux distributions it was hard to showcase
+people the GNUnet features and encourage to participate in the project.
+To show people how the GNUnet project is releasing its software we hereby
+document the current release model:
+* All main development (e.g. towards 0.12.x) continues on master.
+* Developers can continue to develop features in their own feature
+ branches, but are encouraged to frequently merge into master (as long as they
+ don't break the build) to avoid divergence and to detect issues from a
+ merge/rebase early.
+* 0.11.x releases *must* be protocol-compatible to 0.11.0. So once
+ master is NOT protocol-compatible to 0.11.0, development for 0.11.x
+ must continue in an 0.11-branch where we only cherry-pick those
+ changes from master that preserve protocol-compatibility.
+* better CI may allow us to detect breaking changes before merges in the future
+ (but we shall never fault anybody for breaking stuff in master in non-obvious
+ ways);
* actual _release policy_:
- tests must pass
- no compiler warnings for -Wall
- acceptance tests (manual feature test) must succeed
- no known "release critical" bugs (where RC has no formal definition,
mostly we rather explicitly declare certain bugs as "not critical")
+ - Whenever API changes happen the person making that changes should update
+ dependencies or at least work with people who hack on the dependencies to
+ cooridnate the adjustments
