neverpile eureka - The archive system for the cloud generation.

Getting started

The easiest way to get started developing with neverpile eureka is to follow our getting started tutorials. We also have a couple of demos illustrating further concepts.

Current version

Import BOM

<dependencyManagement>
  <dependencies>
    <dependency>
      <groupId>com.neverpile.eureka</groupId>
      <artifactId>neverpile-eureka-bom</artifactId>
      <version>1.8.3</version>
      <type>pom</type>
      <scope>import</scope>
    </dependency>
  </dependencies>

neverpile-eureka's Issues

Get rid of this method

neverpile-eureka/neverpile-eureka-core/src/main/java/com/neverpile/eureka/rest/api/document/content/AllRequestPartsMethodArgumentResolver.java

Line 135 in 759620e

 private static Class<?> getCollectionParameterType(final MethodParameter methodParam) { 

Allow disabling S3 server certificate checking

In some situations it may be necessary to disable server certificate checking. The way this is done differs in AWS SDK Clients v1 and v2. See #11.

Ignite cache get semantics very broken

Cache.get(key) must returns null for misses, but returns new SimpleValueWrapper(null) which signals a cached null value instead.

Implement simple, default non-distributed lock

Add storage adapter for OAM

Object Access Method (OAM) is a storage solution on IBM mainframe systems running z/OS

Enable Hazelcast CP-Subsystem

https://hazelcast.com/blog/hazelcast-imdg-3-12-introduces-cp-subsystem/

DefaultMultiVersioningDocumentService.documentExists(...) broken

Currently returns the opposite of the correct value.

Introduce request-scoped caching for documents

Currently, we have an inefficiency that causes a document GET to trigger multiple retrieve operations of the same backend object. The reason is that DocumentResource.get isn't transactional and all caching in the DefaultDocumentService is based on transactions. For non-transactional cases we shoud fall back to a simple request-scoped cache.

Improve configuration property documentation

Provide typesafe configuration properties with descriptions and validation for improved property editor support.

Change to JUnit 5

Change tests to use JUnit 5

Exclude tomcat from web-start to allow flexible use of servlet engines

Currently web-start still includes tomcat as default servlet engine but also includes undertow

Use Accept-header in filtering content queries

Currently we only support filtering by resource, not by content type.

Implement distributed locking with hazelcast

This is currently not implemented

Reconsider `DocumentService.getDocument(String)`

Do we want to return an empty Optional<Document> or do we want to throw a NotFoundException?

Support tracing

We should support tracing (opentracing), as application performance is dependent on quite a few factors, many of them external.

Improve embeddability

A couple of problems make embedding eureka unnecessarily rough, e.g.

the handling of ModelMapper bean creation and configuration
probably more, TBD

Better exception handling on object not found

Currently we propagate a 500 with the message "Can't walk file tree".

Add OpenAPI spec for the endpoints in MultiVersioningDocumentResource

Add metadata to StoreObject

StoreObject does not support metadata

Simplify naming of storage components

All storage components are named ...bridge.storage..., the element "bridge" seems to be unneccessary because there is no other category below "bridge".

Dropping the intermediate would simplify the component and the package name.

Don't leak sensitive stack information on failures

Currently some service calls propagate sensitive stack trace information in the exception message.

Switch from javax.ws.rs.core.MediaType to its Spring equivalent

We're using both in various places

Unify error classes

Error classes are implemented in various ways:

inner classes
in package classes
in the general com.neverpile.eureka.api.exception package

Choose one and unify all the error classes.

Spring-Boot starter missing from BOM

Remove SpringFox and document the API using hand-crafted OpenAPI/Swagger-specs instead

An incompatibility between Spring-Boot 2.2.x andn the current SpringFix version currently blocks #2. We had lots of problems with SpringFox in the past and the generated models are still unsatisfactory.

Correct configurability for single-versioning mode

ConditionalOnProperty parameterization for com.neverpile.eureka.autoconfig.NeverpileEurekaAutoConfiguration.CoreServiceConfiguration.defaultDocumentService() is broken so that one cannot activate single-versioning mode.

Remove tomcat features

Some classes use tomcat features

Exclude OAuth from neverpile-eureka-spring-boot-starter

In the most simple case an instance should be usable without any authorization (or authorization configured manually/elsewhere), but there is a default dependency on neverpile-eureka-security-oauth2.

Also deploy sources

They are currently missing from the repository.

Improve multipart document creation to support __DOC part without media type

Currently document creation through a multipart/form-data POST requires the main (metadata) part to be supplied with a content-type header set to application/json. This cannot easily be produced by some tools like Postman and is overly difficult with others like Insomnia. The content-type should thus be made optional.
