| − | This document is the plan, and working notes for moving to CBI-based builds. There is still lots to do, and many changes to make, so want to be sure as much is communicated as best as possible.
| + | |
| − | | + | |
| − | We want to be aggressive in adopting CBI based builds for Kepler, but at the same time, responsible. That is, to make sure it is correct -- or, correct enough -- that adopters (or, ourselves!) are not broken by any changes. And, that means "correct enough" from one I-build to the next, not "just by the time we release". This is a new area for most of us so will take a lot of focus.
| + | |
| − | | + | |
| − | The following are the major criteria to judge if/when we are ready to adopt as our primary build and/or release. Any others?
| + | |
| − | | + | |
| − | =Main Criteria for moving to CBI based build for Kepler=
| + | |
| − | | + | |
| − | | + | |
| − | # Have same output deliverables as current build: zips, repository, etc. (For Equinox and Eclipse) | + | |
| − | # (Be able to reproduce exact same build, given a tag (or tags) to start the build with.)
| + | |
| − | # Same warnings (and compile errors, if any) as PDE based build.
| + | |
| − | # Be able to run our JUnit tests, with same results, as PDE based build.
| + | |
| − | # Produces the same Java Doc and Help documentation.
| + | |
| − | # Run a binary comparator against the bundles to ensure that they are the same binary content as the regular bundles.
| + | |
| − | ##[Not sure how to do this since "qualifier algorithm" is different].
| + | |
| − | # Qualifiers not change (except for branding bundles) if the content has not changed.
| + | |
| − | # All bundles signed.
| + | |
| − | # Final I-build type repository have same content and metadata as PDE based build (nothing missing, nothing extra).
| + | |
| − | # Be easy to fit in to current workflow of automated builds and tests of "nightlies", I-builds, milestones (i.e. committers have to know what to do to "release" something for a build, how to "freeze" changes at a certain point).
| + | |
| − | # Don't create maintenance burden by duplicating information ({{bug|387802}})

| − | == The last PDE based build ==
| + | |
| − | | + | |
| − | * '''I20130219-1600''' is the final "PDE Based build". It is recommended for those "building on" Eclipse to move up to that level now, so once they try a "CBI based build", they will have a good comparison if "all is ok" or if something surprising changed, or broke (if so, open a bug, if one doesn't exist; if one exists, add comments so we can better understand impact and priorities).

| + | |
| − | | + | |
| − | * '''Repository'''. Since we are still evaluating version numbering (to make sure they always increase compared to previous I-builds) the repo site at <code>http://download.eclipse.org/eclipse/updates/4.3-I-builds/</code> may not always give the result from the most recent build (for we hope only a short time). Therefore, the repo that corresponds to that "last PDE build", in non-composite form, is documented here:

| − | | + | |
| − | == The first Tycho/Maven based build ==
| + | |
| − | | + | |
| − | * '''I20130222-2000''' is the "first" Tycho/Maven based build. Its distributions such as "SDK" and "Platform", tests framework, etc., all appear to be perfectly usable, though there remains some issues with signing source jars, and similar. But, the following limitations are known and being worked on next:
| + | |
| − | : No repository put at ...eclipse/updates/4.3-I-builds/
| + | |
| − | : Some of the "zipped repositories" are not complete.
| + | |
| − | : No Equinox drops

| + | |
| − | | + | |
| − | Weeks below are numbered in "milestone weeks", beginning with "towards M6" ... there are only 6 weeks for M6.
| + | |
| − | | + | |
| − | == Towards M6 ==
| + | |
| − | | + | |
| − | === Week 2: (2/11 - 15) ===
| + | |
| − | | + | |
| − | :Begin to produce daily automated CBI based builds and run unit tests in parallel with PDE-based builds.
| + | |
| − | ::I'll schedule these to start at 8:11 PM, same time as PDE-based Nightlies and same time as weekly I-builds.
| + | |
| − | ::Initially, all CBI based builds (even "nightlies") will be "I-builds" to better assess versioning, and more work is need to implement "nightly vs. integration" builds.
| + | |
| − | :::I builds will build against master, controlled by [http://git.eclipse.org/c/platform/eclipse.platform.releng.aggregator.git/tree/streams/repositories.txt repositories.txt]
| + | |
| − | ::(Unit tests on Linux only, until those work as expected, to save Windows and Mac machine resources).
| + | |
| − | | + | |
| − | :During this week "announce" the CBI based builds available, get community/adopter help in testing adequacy.
| + | |
| − | | + | |
| − | :Committers should begin to use SDK's produced, and evaluate for correctness. In particular:
| + | |
| − | ::Check that version numbers change (or don't change) as expected. (I recommend you make some change, even trivial, to make sure it "gets in to" a build, if not otherwise planning changes this week).
| + | |
| − | ::Those with "binary bundles" check that they are correct ones.
| + | |
| − | ::Help evaluate failing JUnit suites. Some may be "releng" issues, but some may be project pom issues?
| + | |
| − |
| + | |
| − | :Initial Limitations: (meaning of priorities: high, need before making primary; medium, need before release; low, probably need at some point)
| + | |
| − | ::there will be no "autotagging" of aggregator or repositories, until we are more confident. (medium priority)
| + | |
| − | ::there will be no "equinox drops". (low/medium priority)
| + | |
| − | ::there will be no cbibased "I-build repo" (high priority)
| + | |
| − | ::"zipped repos" are known not to be quite right yet (low prioriy)
| + | |
| − | ::no ecj.jar produced (in hands of JDT Team? To tweak their "custom script"?) (low priority)
| + | |
| − | ::no "auto update" of pom's, based on manifest ... such as committers have to update version number in both, make "build.properties" changes in both. (low priority)
| + | |
| − | | + | |
| − | === Week 3: (2/18 - 22) ===
| + | |
| − | | + | |
| − | : Cut over to CBI based builds as primary (unless someone raising a true, blocking objection). '''[done. 2/20]'''
| + | |
| − | | + | |
| − | :Begin to tag aggregator upon successful build, (with "commits" of latest submodules added to aggregator). '''[done. 2/20]'''
| + | |
| − | ::(This allows "local build" to duplicate our build following directions given at [[Platform-releng/Platform_Build| Platform Build wiki]])
| + | |
| − | ::TODO: someone (Thanh?) should confirm it gives same "target" results?)
| + | |
| − | | + | |
| − | === Week 4: (2/25 - 3/1) ===
| + | |
| − | | + | |
| − | :Begin to produce "4.3-I-build" repositories at .../eclipse/updates {{bug|393927}}.
| + | |
| − | | + | |
| − | :Will make "massive" coordinated change to update all pom groupIds {{bug|397850}} and the eclipse parent pom renamed {{bug|394831}}.
| + | |
| − | | + | |
| − | : Some projects may need to "touch" their projects to get qualifiers "in order" (there is a difference in heuristics used for qualifiers so some in CBI build might be "lower than" those produced by PDE, in theory).
| + | |
| − | | + | |
| − | === Week 5: (3/4 - 8) ===
| + | |
| − | | + | |
| − | :Possibly this week start to have true "CBI nightlies" vs. "Integration".
| + | |
| − | | + | |
| − | === Week 6: (3/11 - 15) <== 3/15 is M6+0 day. ===
| + | |
