Motivation:
At the moment we always build all modules. This script can be used to only build affected modules for a given change
Modifications:
Add script that will only build modules that are affected by a change
Result:
More targeted build
Motivation:
In Netty 5 we wish to have a simpler, safe, future proof, and more consistent buffer API.
We developed such an API in the incubating buffer repository, and taking it through multiple rounds of review and adjustments.
This PR/commit bring the results of that work into the Netty 5 branch of the main Netty repository.
Modifications:
* `Buffer` is an interface, and all implementations are hidden behind it.
There is no longer an inheritance hierarchy of abstract classes and implementations.
* Reference counting is gone.
After a buffer has been allocated, calling `close` on it will deallocate it.
It is then up to users and integrators to ensure that the life-times of buffers are managed correctly.
This is usually not a problem as buffers tend to flow through the pipeline to be released after a terminal IO operation.
* Slice and duplicate methods are replaced with `split`.
By removing slices, duplicate, and reference counting, there is no longer a possibility that a buffer and/or its memory can be shared and accessible through multiple routes.
This solves the problem of data being accessed from multiple places in an uncoordinated way, and the problem of buffer memory being closed while being in use by some unsuspecting piece of code.
Some adjustments will have to be made to other APIs, idioms, and usages, since `split` is not always a replacement for `slice` in some use cases.
* The `split` has been added which allows memory to be shared among multiple buffers, but in non-overlapping regions.
When the memory regions don't overlap, it will not be possible for the different buffers to interfere with each other.
An internal, and completely transparent, reference counting system ensures that the backing memory is released once the last buffer view is closed.
* A Send API has been introduced that can be used to enforce (in the type system) the transfer of buffer ownership.
This is not expected to be used in the pipeline flow itself, but rather for other objects that wrap buffers and wish to avoid becoming "shared views" — the absence of "shared views" of memory is important for avoiding bugs in the absence of reference counting.
* A new BufferAllocator API, where the choice of implementation determines factors like on-/off-heap, pooling or not.
How access to the different allocators will be exposed to integrators will be decided later.
Perhaps they'll be directly accessible on the `ChannelHandlerContext`.
* The `PooledBufferAllocator` has been copied and modified to match the new allocator API.
This includes unifying its implementation that was previously split across on-heap and off-heap.
* The `PooledBufferAllocator` implementation has also been adjusted to allocate 4 MiB chunks by default, and a few changes have been made to the implementation to make a newly created, empty allocator use significantly less heap memory.
* A `Resource` interface has been added, which defines the life-cycle methods and the `send` method.
The `Buffer` interface extends this.
* Analogues for `ByteBufHolder` has been added in the `BufferHolder` and `BufferRef` classes.
* `ByteCursor` is added as a new way to iterate the data in buffers.
The byte cursor API is designed to be more JIT friendly than an iterator, or the existing `ByteProcessor` interface.
* `CompositeBuffer` no longer permit the same level of access to its internal components.
The composite buffer enforces its ownership of its components via the `Send` API, and the components can only be individually accessed with the `forEachReadable` and `forEachWritable` methods.
This keeps the API and behavioral differences between composite and non-composite buffers to a minimum.
* Two implementations of the `Buffer` interface are provided with the API: One based on `ByteBuffer`, and one based on `sun.misc.Unsafe`.
The `ByteBuffer` implementation is used by default.
More implementations can be loaded from the classpath via service loading.
The `MemorySegment` based implementation is left behind in the incubator repository.
* An extensive and highly parameterised test suite has been added, to ensure that all implementations have consistent and correct behaviour, regardless of their configuration or composition.
Result:
We have a new buffer API that is simpler, better tested, more consistent in behaviour, and safer by design, than the existing `ByteBuf` API.
The next legs of this journey will be about integrating this new API into Netty proper, and deprecate (and eventually remove) the `ByteBuf` API.
This fixes#11024, #8601, #8543, #8542, #8534, #3358, and #3306.
Motivation:
Native image compatibility is fragile and breaks easily, so we need a PR build to tell us when this happens.
Modification:
Add a graalvm-based build to the PR build matrix.
Result:
Every PR is now also tested on Graal.
Motivation:
When Maven does not run in batch mode, it will continuously print its progress as it downloads dependencies.
This can produce a very large amount of log output, that makes it harder to debug build failures.
Modification:
Make all Maven builds run in batch mode by adding the `-B` command line flag, and have transfer progress suppressed with the `-ntp` flag.
Some builds were already running batch mode but had the flag in a different location – these have had their `-B` flag moved so all builds are consistent.
Result:
Much less output in our build logs where Maven is just downloading stuff.
Motivation:
Let's also build on windows during PR validation
Modifications:
Add build on windows during PR
Result:
Validate that all also pass on windows
Motivation:
Just use MAVEN_OPTS to setup all the timeouts etc for dependency downloads. This way we at least can be sure these are applied.
Modifications:
- Use MAVEN_OPTS
- Remove ci profile
- Remove unused settings.xml file
- Always use ./mvnw
Result:
Build stability improvements
Motivation:
We should setup the caching so it will be able to use different restore keys and so almost never need to start from scratch
Modifications:
Adjust caching config to make use of different restore keys for maven caching but also docker caching
Result:
Better cache usage
Motivation:
We should use the same maven cache for all builds so we can re-use as much of the downloaded maven dependencies as possible
Modifications:
- Just use the same cache for all
Result:
Hopefully be able to re-use most of the dependencies
Motivation:
0f25213918 introduced some properties that were used to make builds more stable on the ci. All of these properties were duplicated everywhere, this made it hard to maintain
Modifications:
- Add profile which sets the properties.
- Just use the profile when build on the ci
Result:
Easier to maintain custom properties for the ci build
Motivation:
It seems like it is a known issue that maven frequently sees connection reset / connection timeout during CI builds. We should workaround these issues like others did:
- https://github.com/kiegroup/kie-wb-common/pull/3416
Modifications:
Add extra maven options during build to reduce the likelyness of timeouts / resets
Result:
More stable builds
Motivation:
The last non-LTS release is JDK16 now.
Modifications:
Update from JDK15 to JDK16 for building as this is the last non-LTS release atm
Result:
Build with latest non-LTS release as well
Motivation:
In the past we did see problems sometime when run-on-arch-action was used. We are multiple releases behind, lets update and so maybe fix the problems.
Modifications:
Update to latest release
Result:
Use latest run-on-arch-action release
Motivation:
It turned out we didnt run the openssl tests on the CI when we used the non-static version of netty-tcnative.
Modifications:
- Upgrade netty-tcnative to fix segfault when using shared openssl
- Adjust tests to only run session cache tests when openssl supports it
- Fix some more tests to only depend on KeyManager if the underlying openssl version supports it
Result:
Run all openssl test on the CI even when shared library is used
Motivation:
Newer versions of dawidd6/action-download-artifact changed the default
workflow_conclusion from "completed" to "completed, success" which can
result in download failures if the associated job fails, which is
expected when tests fail.
Modifications:
- Explicitly set the workflow_conclusion to "completed"
Result:
Test failures which result in build failures will still download test
data and generate reports after updating
dawidd6/action-download-artifact.
This brings forward the build and release automation changes from 4.1 (#10879, #10883, #10884, #10886, #10888, #10889, #10893, #10900, #10933, #10945, #10966, #10968, #11002, and #11019) to 5.0.
Details are as follows:
* Use Github workflows for CI (#10879)
Motivation:
We should just use GitHub Actions for the CI
Modifications:
- Adjust docker / docker compose files
- Add different workflows and jobs to deploy and build the project
Result:
Don't depend on external CI services
* Fix non leak build condition
* Only use build and deploy workflows for 4.1 for now
* Add deploy job for cross compiled aarch64 (#10883)
Motivation:
We should also deploy snapshots for our cross compiled native jars.
Modifications:
- Add job and docker files for deploying cross compiled native jars
- Ensure we map the maven cache into our docker containers
Result:
Deploy aarch64 jars and re-use cache
* Use correct docker-compose file to deploy cross compiled artifacts
* Use correct docker-compose task to deploy for cross compiled artifacts
* Split pr and normal build (#10884)
Motivation:
We should better use seperate workflows for PR and normal builds
Modifications:
- Split workflows
- Better cache reuse
Result:
Cleanup
* Only deploy snapshots for one arch
Motivation:
We need to find a way to deploy SNAPSHOTS for different arch with the same timestamp. Otherwise it will cause problems.
See https://github.com/netty/netty/issues/10887
Modification:
Skip all other deploys then x86_64
Result:
Users are able to use SNAPSHOTS for x86_6
* Use maven cachen when running analyze job (#10888)
Motivation:
To prevent failures to problems while downloading dependencies we shoud cache these
Modifications:
Add maven cache
Result:
No more failures due problems while downloading dependencies
* Also include one PR job that uses boringssl (#10886)
Motivation:
When validating PRs we should also at least run one job that uses boringssl
Modifications:
- Add job that uses boringssl
- Cleanup docker compose files
- Fix buffer leak in test
Result:
Also run with boringssl when PRs are validated
* Use matrix for job configurations (#10889)
Motivation:
We can use the matrix feature to define our jobs. This reduces a lot of config
Modification:
Use job matrix
Result:
Easier to maintain
* Correctly deploy artifacts that are build on different archs (#10893)
Motivation:
We need to take special care when deploying snapshots as we need to generate the jars in multiple steps
Modifications:
- Use the nexus staging pluging to stage jars locally in multiple steps
- Add extra job that will merge these staged jars and deploy these
Result:
Fixes https://github.com/netty/netty/issues/10887
* Dont use cron for PRs
Motivation:
It doesnt make sense to use cron for PRs
Modifications:
Remove cron config
Result:
Cleanup
* We run all combinations when validate the PR, let's just use one type for normal push
Motivation:
Let us just only use one build config when building the 4.1 branch.
Modifications:
As we already do a full validation when doing the PR builds we can just only use one build config for pushes to the "main" branches
Result:
Faster build times
* Update action-docker-layer-caching (#10900)
Motivation:
We are three releases behind.
Modifications:
Update to latest version
Result:
Use up-to-date action-docker-layer-caching version
* Verify we can load native modules and add job that verifies on aarch64 as well (#10933)
Motivation:
As shown in the past we need to verify we actually can load the native as otherwise we may introduce regressions.
Modifications:
- Add new maven module which tests loading of native modules
- Add job that will also test loading on aarch64
Result:
Less likely to introduce regressions related to loading native code in the future
* Let script fail if one command fail (#10945)
Motivation:
We should use `set -e` to ensure we fail the script if one command fails.
Modifications:
Add set -e to script
Result:
Fail fast
* Use action to report unit test errors (#10966)
Motivation:
To make it easier to understand why the build fails lets use an action that will report which unit test failed
Modifications:
- Replace custom script with action-surefire-report
Result:
Easier to understand test failures
* Use custom script to check for build failures (#10968)
Motivation:
It turns out we can't use the action to check for build failures as it can't be used when a PR is done from a fork. Let's just use our simple script.
Modifications:
- Replace action with custom script
Result:
Builds for PRs that are done via forks work again.
* Publish test results after PR run (#11002)
Motivation:
To make it easier to understand why a build failed let us publish the rest results
Modifications:
Use a new workflow to be able to publish the test reports
Result:
Easier to understand why a PR did fail
* Fix test reports name
* Add workflow to cut releases (#11019)
Motivation:
Doing releases manually is error-prone, it would be better if we could do it via a workflow
Modification:
- Add workflow to cut releases
- Add related scripts
Result:
Be able to easily cut a release via a workflow
* Update build for master branch
Motivation:
The build changes were brought forward from 4.1, and contain many things specific to 4.1.
Modification:
Changed baseline Java version from 8 to 11, and changed branch references from "4.1" to "master".
Result:
Builds should now work for the master branch.
Co-authored-by: Norman Maurer <norman_maurer@apple.com>
Motivation:
Printing download progress in the build log makes it harder to see what's wrong when the build fails.
Modification:
Change the maven command to not show transfer progress, also enable batch mode so Maven don't print in colors that we can't see anyway.
Result:
More concise code analysis build logs.
Motivation:
Github now allows to run CodeQL during pull request verification. This allows to detect errors / security problems early.
Modification:
Add config
Result:
Fixes https://github.com/netty/netty/issues/10669
Co-authored-by: Artem Smotrakov <artem.smotrakov@sap.com>
Motivation:
Netty homepage(netty.io) serves both "http" and "https".
It's recommended to use https than http.
Modification:
I changed from "http://netty.io" to "https://netty.io"
Result:
No effects.
