-== Spring Framework Concourse pipeline
-
-NOTE: CI is being migrated to GitHub Actions.
-
-The Spring Framework uses https://concourse-ci.org/[Concourse] for its CI build and other automated tasks.
-The Spring team has a dedicated Concourse instance available at https://ci.spring.io with a build pipeline
-for https://ci.spring.io/teams/spring-framework/pipelines/spring-framework-5.3.x[Spring Framework 5.3.x].
-
-=== Setting up your development environment
-
-If you're part of the Spring Framework project on GitHub, you can get access to CI management features.
-First, you need to go to https://ci.spring.io and install the client CLI for your platform (see bottom right of the screen).
-
-You can then login with the instance using:
-
-[source]
----
-$ fly -t spring login -n spring-framework -c https://ci.spring.io
----
-
-Once logged in, you should get something like:
-
-[source]
----
-$ fly ts
-name                  url                   team                  expiry
-spring                https://ci.spring.io  spring-framework      Wed, 25 Mar 2020 17:45:26 UTC
----
-
-=== Pipeline configuration and structure
-
-The build pipelines are described in `pipeline.yml` file.
-
-This file is listing Concourse resources, i.e. build inputs and outputs such as container images, artifact repositories, source repositories, notification services, etc.
-
-It also describes jobs (a job is a sequence of inputs, tasks and outputs); jobs are organized by groups.
-
-The `pipeline.yml` definition contains `((parameters))` which are loaded from the `parameters.yml` file or from our https://docs.cloudfoundry.org/credhub/[credhub instance].
-
-You'll find in this folder the following resources:
-
-* `pipeline.yml` the build pipeline
-* `parameters.yml` the build parameters used for the pipeline
-* `images/` holds the container images definitions used in this pipeline
-* `scripts/` holds the build scripts that ship within the CI container images
-* `tasks` contains the task definitions used in the main `pipeline.yml`
-
-=== Updating the build pipeline
-
-Updating files on the repository is not enough to update the build pipeline, as changes need to be applied.
-
-The pipeline can be deployed using the following command:
-
-[source]
----
-$ fly -t spring set-pipeline -p spring-framework-5.3.x -c ci/pipeline.yml -l ci/parameters.yml
----
-
-NOTE: This assumes that you have credhub integration configured with the appropriate secrets.

-To build the image locally run the following from this directory:

-For example

Sam Brannen	26f2dad388	Enforce read-only semantics in SpEL's SimpleEvaluationContext SimpleEvaluationContext.forReadOnlyDataBinding() documents that it creates a SimpleEvaluationContext for read-only access to public properties; however, prior to this commit write access was not disabled for indexed structures when using the assignment operator, the increment operator, or the decrement operator. In order to better align with the documented contract for forReadOnlyDataBinding(), this commit makes it possible to disable assignment in general in order to enforce read-only semantics for SpEL's SimpleEvaluationContext when created via the forReadOnlyDataBinding() factory method. Specifically: - This commit introduces a new isAssignmentEnabled() "default" method in the EvaluationContext API, which returns true by default. - SimpleEvaluationContext overrides isAssignmentEnabled(), returning false if the context was created via the forReadOnlyDataBinding() factory method. - The Assign, OpDec, and OpInc AST nodes -- representing the assignment (=), increment (++), and decrement (--) operators, respectively -- now throw a SpelEvaluationException if assignment is disabled for the current EvaluationContext. See gh-33319 Closes gh-33320 (cherry picked from commit `e1ab306506`)	2024-08-06 14:31:44 +03:00
Sam Brannen	7e390784ba	Throw exception for failure to set property as index in SpEL Prior to this commit, the Indexer in the Spring Expression Language (SpEL) silently ignored a failure to set a property via the indexed property syntax (['<property name>'] = <new value>) – for example, if property write access was disabled in the EvaluationContext. This commit addresses this issue by properly throwing a SpelEvaluationException in PropertyIndexingValueRef.setValue(Object) if the property could not be set.

Sam Brannen	dffb6c5bb6	Support single String argument for varargs invocations in SpEL Prior to this commit, the Spring Expression Language (SpEL) incorrectly split single String arguments by comma for Object... varargs method and constructor invocations.
