+# Remote Build Cache Server
+Remote Build Cache Server (shortened to RBCS) allows you to share and reuse unchanged build 
+and test outputs across the team. This speeds up local and CI builds since cycles are not wasted
+re-building components that are unaffected by new code changes. RBCS supports both Gradle and
+Maven build tool environments.
+
+It comes with pluggable storage backends, the core application offers in-memory storage or disk-backed storage,
+in addition to this there is an official plugin to use memcached as the storage backend.
+
+It supports HTTP basic authentication or, alternatively, TLS certificate authentication, role-based access control (RBAC),
+and throttling.
+
+## Quickstart
+
+### Downloading the jar file 
+You can download the latest version from [this link](https://gitea.woggioni.net/woggioni/-/packages/maven/net.woggioni:rbcs-cli/)
+
+Assuming you have Java 21 or later installed, you can launch the server directly with
+
+```bash
+java -jar rbcs-cli.jar server
+```
+
+By default it will start an HTTP server bound to localhost and listening on port 8080 with no authentication,
+writing data to the disk, that you can use for testing
+
+### Using the Docker image
+You can pull the latest Docker image with
+```bash
+docker pull gitea.woggioni.net/woggioni/rbcs:latest
+```
+
+By default it will start an HTTP server bound to localhost and listening on port 8080 with no authentication,
+writing data to the disk, that you can use for testing
+
+## Usage
+
+### Configuration
+The location of the `rbcs.xml` configuration file depends on the operating system, 
+Alternatively it can be changed setting the `RBCS_CONFIGURATION_DIR` environmental variable or `net.woggioni.rbcs.conf.dir` Java system property
+to the directory that contain the `rbcs.xml` file.
+
+The server configuration file follows the XML format and uses XML schema for validation
+(you can find the schema for the main configuration file [here](https://gitea.woggioni.net/woggioni/rbcs/src/branch/master/rbcs-server/src/main/resources/net/woggioni/rbcs/server/schema/rbcs.xsd)).
+
+The configuration values are enclosed inside XML attribute and support system property / environmental variable interpolation.
+As an example, you can configure RBCS to read the server port number from the `RBCS_SERVER_PORT` environmental variable
+and the bind address from the `rbc.bind.address` JVM system property with.
+
+Full documentation for all tags and attributes is available [here](doc/server_configuration.md).
+
+### Plugins
+If you want to use memcache as a storage backend you'll also need to download [the memcache plugin](https://gitea.woggioni.net/woggioni/-/packages/maven/net.woggioni:rbcs-server-memcache/)
+
+Plugins need to be stored in a folder named `plugins` in the located server's working directory
+(the directory where the server process is started). They are shipped as TAR archives, so you need to extract
+the content of the archive into the `plugins` directory for the server to pick them up.
+
+### Using RBCS with Gradle 
+
+Add this to the `settings.gradle` file of your project
+
+```groovy
+buildCache {
+    remote(HttpBuildCache) {
+        url = 'https://rbcs.example.com/'
+        push = true
+        allowInsecureProtocol = false
+        // The credentials block is only required if you enable 
+        // HTTP basic authentication on RBCS
+        credentials {
+            username = 'build-cache-user'
+            password = 'some-complicated-password'
+        }
+    }
+}
+```
+
+alternatively you can add this to `${GRADLE_HOME}/init.gradle` to configure the remote cache
+at the system level
+
+```groovy
+gradle.settingsEvaluated { settings ->
+    settings.buildCache {
+        remote(HttpBuildCache) {
+            url = 'https://rbcs.example.com/'
+            push = true
+            allowInsecureProtocol = false
+            // The credentials block is only required if you enable 
+            // HTTP basic authentication on RBCS
+            credentials {
+                username = 'build-cache-user'
+                password = 'some-complicated-password'
+            }
+        }
+    }
+}
+```
+
+add `org.gradle.caching=true` to your `<project>/gradle.properties` or run gradle with `--build-cache`.
+
+Read [Gradle documentation](https://docs.gradle.org/current/userguide/build_cache.html) for more detailed information.
+
+### Using RBCS with Maven
+
+1. Create an `extensions.xml` in `<project>/.mvn/extensions.xml` with the following content
+  ```xml
+  <extensions xmlns="http://maven.apache.org/EXTENSIONS/1.1.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
+            xsi:schemaLocation="http://maven.apache.org/EXTENSIONS/1.1.0 https://maven.apache.org/xsd/core-extensions-1.0.0.xsd">
+      <extension>
+          <groupId>org.apache.maven.extensions</groupId>
+          <artifactId>maven-build-cache-extension</artifactId>
+          <version>1.2.0</version>
+      </extension>
+  </extensions>
+  ```
+2. Copy [maven-build-cache-config.xml](https://maven.apache.org/extensions/maven-build-cache-extension/maven-build-cache-config.xml) into `<project>/.mvn/` folder
+3. Edit the `cache/configuration/remote` element
+  ```xml
+    <remote enabled="true" id="rbcs">
+        <url>https://rbcs.example.com/</url>
+    </remote>
+  ```
+4. Run maven with
+  ```bash
+    mvn -Dmaven.build.cache.enabled=true -Dmaven.build.cache.debugOutput=true -Dmaven.build.cache.remote.save.enabled=true package
+  ```
+
+Alternatively you can set those properties in your `<project>/pom.xml`
+
+
+Read [here](https://maven.apache.org/extensions/maven-build-cache-extension/remote-cache.html)

+## FAQ
+### Why should I use a build cache?
+
+#### Build Caches Improve Build & Test Performance
+
+Building software consists of a number of steps, like compiling sources, executing tests, and linking binaries. We’ve seen that a binary artifact repository helps when such a step requires an external component by downloading the artifact from the repository rather than building it locally.
+However, there are many additional steps in this build process which can be optimized to reduce the build time. An obvious strategy is to avoid executing build steps which dominate the total build time when these build steps are not needed.
+Most build times are dominated by the testing step. 
+
+While binary repositories cannot capture the outcome of a test build step (only the test reports 
+when included in binary artifacts), build caches are designed to eliminate redundant executions 
+for every build step. Moreover, it generalizes the concept of avoiding work associated with any 
+incremental step of the build, including test execution, compilation and resource processing. 
+The mechanism itself is comparable to a pure function. That is, given some inputs such as source 
+files and  environment parameters we know that the output is always going to be the same. 
+As a result, we can cache it and retrieve it based on a simple cryptographic hash of the inputs.
+Build caching is supported natively by some build tools. 
+
+#### Improve CI builds with a remote build cache
+
+When analyzing the role of a build cache it is important to take into account the granularity 
+of the changes that it caches. Imagine a full build for a project with 40 to 50 modules 
+which fails at the last step (deployment) because the staging environment is temporarily unavailable.
+Although the vast majority of the build steps (potentially thousands) succeed, 
+the change can not be deployed to the staging environment. 
+Without a build cache one typically relies on a very complex CI configuration to reuse build step outputs
+or would have to repeat the full build once the environment is available.
+
+Some build tools don’t support incremental builds properly. For example, outputs of a build started
+from scratch may vary when compared to subsequent builds that rely on the initial build’s output.
+As a result, to preserve build integrity, it’s crucial to rebuild from scratch, or ‘cleanly,’ in this
+scenario.
+
+With a build cache, only the last step needs to be executed and the build can be re-triggered 
+when the environment is back online. This automatically saves all of the time and 
+resources required across the different build steps which were successfully executed. 
+Instead of executing the intermediate steps, the build tool pulls the outputs from the build cache,
+avoiding a lot of redundant work
+
+#### Share outputs with a remote build cache
+
+One of the most important advantages of a remote build cache is the ability to share build outputs. 
+In most CI configurations, for example, a number of pipelines are created.
+These may include one for building the sources, one for testing, one for publishing the outcomes 
+to a remote repository, and other pipelines to test on different platforms. 
+There are even situations where CI builds partially build a project (i.e. some modules and not others).
+
+Most of those pipelines share a lot of intermediate build steps. All builds which perform testing
+require the binaries to be ready. All publishing builds require all previous steps to be executed.
+And because modern CI infrastructure means executing everything in containerized (isolated) environments,
+significant resources are wasted by repeatedly building the same intermediate artifacts.
+
+A remote build cache greatly reduces this overhead by orders of magnitudes because it provides a way
+for all those pipelines to share their outputs. After all, there is no point recreating an output that
+is already available in the cache.
+
+Because there are inherent dependencies between software components of a build,
+introducing a build cache dramatically reduces the impact of exploding a component into multiple pieces,
+allowing for increased modularity without increased overhead.
+
+#### Make local developers more efficient with remote build caches
+
+It is common for different teams within a company to work on different modules of a single large
+application. In this case, most teams don’t care about building the other parts of the software.
+By introducing a remote cache developers immediately benefit from pre-built artifacts when checking out code. 
+Because it has already been built on CI, they don’t have to do it locally.
+
+Introducing a remote cache is a huge benefit for those developers. Consider that a typical developer’s
+day begins by performing a code checkout. Most likely the checked out code has already been built on CI.
+Therefore, no time is wasted running the first build of the day. The remote cache provides all of the
+intermediate artifacts needed. And, in the event local changes are made, the remote cache still leverages
+partial cache hits for projects which are independent. As other developers in the organization request 
+CI builds, the remote cache continues to populate, increasing the likelihood of these remote cache hits
+across team members.

+# RBCS Docker images
+There are 3 image flavours:
+- vanilla
+- memcache
+- native
+
+The `vanilla` image only contains the envelope 
+jar file with no plugins and is based on `eclipse-temurin:21-jre-alpine`
+
+The `memcache` image is similar to the `vanilla` image, except that it also contains
+the `rbcs-server-memcache` plugin in the `plugins` folder, use this image if you don't want to use the `native`
+image and want to use memcache as the cache backend
+
+The `native` image contains a native, statically-linked executable created with GraalVM
+that has no userspace dependencies. It also embeds the memcache plugin inside the executable.
+Use this image for maximum efficiency and minimal memory footprint.

+## Which image shoud I use?
+The `native` image uses Java's SerialGC, so it's ideal for constrained environment like containers or small servers,
+if you have a lot of resources and want to squeeze out the maximum throughput you should consider the
+`vanilla` or `memcache` image, then choose and fine tune the garbage collector.
+
+Also the `native` image is only available for the `x86_64` architecture at the moment, 
+while `vanilla` and `memcache` also ship a `aarch64` variant.

+# RBCS Memcache plugins
+
+This plugins allows RBCs to store and retrieve data from a memcache cluster.
+The memcache server selection is simply based on the hash of the key, 
+deflate compression is also supported and performed by the RBCS server
+
+## Quickstart
+The plugin can be built with
+```bash
+./gradlew rbcs-server-memcache:bundle
+```
+which creates a `.tar` archive in the `build/distributions` folder. 
+The archive is supposed to be extracted inside the RBCS server's `plugins` directory.
+
+## Configuration
+
+The plugin can be enabled setting the `xs:type` attribute of the `cache` element
+to `memcacheCacheType`.
+
+The plugins currently supports the following configuration attributes:
+- `max-age`: the amount of time cache entries will be retained on memcache
+- `digest`: digest algorithm to use on the key before submission 
+  to memcache (optional, no digest is applied if omitted)
+- `compression`: compression algorithm to apply to cache values before, 
+  currently only `deflate` is supported (optionla, if omitted compression is disabled)
+- `compression-level`: compression level to use, deflate supports compression levels from 1 to 9, 
+  where 1 is for fast compression at the expense of speed (optional, 6 is used if omitted)
