Refactor to clean up packages in the t-model and to introduce a simpler to implement t-engine base.
The new t-engines (tika, imagemagick, libreoffice, pdfrenderer, misc, aio, aspose) and t-router may be used in combination with older components as the API between the content Repo and between components has not changed. As far as possible the same artifacts are created (the -boot projects no longer exist). They may be used with older ACS repo versions.
The main changes to look for are:
* The introduction of TransformEngine and CustomTransformer interfaces to be implemented.
* The removal in t-engines and t-router of the Controller, Application, test template page, Controller tests and application config, as this is all now done by the t-engine base package.
* The t-router now extends the t-engine base, which also reduced the amount of duplicate code.
* The t-engine base provides the test page, which includes drop downs of known transform options. The t-router is able to use pipeline and failover transformers. This was not possible to do previously as the router had no test UI.
* Resources including licenses are automatically included in the all-in-one t-engine, from the individual t-engines. They just need to be added as dependencies in the pom.
* The ugly code in the all-in-one t-engine and misc t-engine to pick transformers has gone, as they are now just selected by the transformRegistry.
* The way t-engines respond to http or message queue transform requests has been combined (eliminates the similar but different code that existed before).
* The t-engine base now uses InputStream and OutputStream rather than Files by default. As a result it will be simpler to avoid writing content to a temporary location.
* A number of the Tika and Misc CustomTransforms no longer use Files.
* The original t-engine base still exists so customers can continue to create custom t-engines the way they have done previously. the project has just been moved into a folder called deprecated.
* The folder structure has changed. The long "alfresco-transform-..." names have given way to shorter easier to read and type names.
* The t-engine project structure now has a single project rather than two.
* The previous config values still exist, but there are now a new set for config values for in files with names that don't misleadingly imply they only contain pipeline of routing information.
* The concept of 'routing' has much less emphasis in class names as the code just uses the transformRegistry.
* TransformerConfig may now be read as json or yaml. The restrictions about what could be specified in yaml has gone.
* T-engines and t-router may use transform config from files. Previously it was just the t-router.
* The POC code to do with graphs of possible routes has been removed.
* All master branch changes have been merged in.
* The concept of a single transform request which results in multiple responses (e.g. images from a video) has been added to the core processing of requests in the t-engine base.
* Many SonarCloud linter fixes.
* Merge alfresco-transform-model project into alfresco-transform-core - WITHOUT the git history
* Simplify Maven dependencies and build project
* Unify release process of combined t-model and t-core
* ACS-2499 Delete company release build stage.
This never uploaded any software, and so was not particularly useful. The software and license report should be
uploaded to S3 as part of the transform-service build.
Also skip uploading anything to staging bucket.
A new constructor has been added to the TikaController to provide
the new spring config.
The creation of the TikaExecutor has been moved to "singleton pattern" as
the injection of the @Value happens after the instantiation of the
TikaJavaExecutor and does not pass the value correctly. The
instantiation is now done once, on the first transform request.
Param has been added to the AIO beans.
* MNT-21869 libreoffice timeout set too high
Reduce default value of timeout for libreoffice from 2000min to 20min
Add option to configure libreoffice timeout externally.
Enable to configure externally the port on which the app starts.
Add external-engine-configuration.md
* ATS-421 : ATS-400: Create Travis build for "alfresco-transform-core"
- rename mvn profile from 'enterpriseDocker' to 'local'
- add config to publish docker image on both Quay and Docker
- remove unused 'master' profile - similar to ATS, publish images only from master branch and on Release
- update <distributionManagement> to publish artefacts to Nexus public (rather than Enterprise Releases)
- add travis build configs
- include SP branches to travis build
- add documentation on build&release process
- updates based on initial review comments, including
-- fix typo (s/successful/failed)
-- add example error status code
-- add link to Alfresco SFS API spec
- also slight re-wording of /transform description
