Parsing is currently very lenient, which has the bad side-effect that if you
have a typo and pass eg. `store: fasle` this will actually be interpreted as
`store: true`. Since mappings can't be changed after the fact, it is quite bad
if it happens on an index that already contains data.
Note that this does not cover all settings that accept a boolean, but since the
PR was quite hard to build and already covers some main settirgs like `store`
or `doc_values` this would already be a good incremental improvement.
The rest test framework, because it used to be tightly integrated with
ESIntegTestCase, currently expects the addresses for the test cluster to
be passed using the transport protocol port. However, it only uses this
to then find the http address.
This change makes ESRestTestCase extend from ESTestCase instead of
ESIntegTestCase, and changes the sysprop used to tests.rest.cluster,
which now takes the http address.

Site plugins used to be used for things like kibana and marvel, but
there is no longer a need since kibana (and marvel as a kibana plugin)
uses node.js. This change removes site plugins, as well as the flag for
jvm plugins. Now all plugins are jvm plugins.
DocumentMapperParser has both parse and parseCompressed methods. Except that the
parse methods are ONLY used from the unit tests. This commit removes the parse
method and moves all tests to parseCompressed so that they test more
realistically how mappings are managed.
Then I renamed parseCompressed to parse given that this is the only alternative
anyway.
This fixes the `lenient` parameter to be `missingClasses`. I will remove this boolean and we can handle them via the normal whitelist.
It also adds a check for sheisty classes (jar hell with the jdk).
This is inspired by the lucene "sheisty" classes check, but it has false positives. This check is more evil, it validates every class file against the extension classloader as a resource, to see if it exists there. If so: jar hell.
This jar hell is a problem for several reasons:
1. causes insanely-hard-to-debug problems (like bugs in forbidden-apis)
2. hides problems (like internal api access)
3. the code you think is executing, is not really executing
4. security permissions are not what you think they are
5. brings in unnecessary dependencies
6. its jar hell
The more difficult problems are stuff like jython, where these classes are simply 'uberjared' directly in, so you cant just fix them by removing a bogus dependency. And there is a legit reason for them to do that, they want to support java 1.4.
When creating a metadata mapper for a new type, we reuse an existing
configuration from an existing type (if any) in order to avoid introducing
conflicts. However this field type that is provided is considered as both an
initial configuration and the default configuration. So at serialization time,
we might only serialize the difference between the current configuration and
this default configuration, which might be different to what is actually
considered the default configuration.
This does not cause bugs today because metadata mappers usually override the
toXContent method and compare the current field type with Defaults.FIELD_TYPE
instead of defaultFieldType() but I would still like to do this change to
avoid future bugs.
The `path` option allowed to index/store a field `a.b.c` under just `c` when
set to `just_name`. This "feature" has been removed in 2.0 in favor of `copy_to`
so we can remove the back compat in 3.x.
Today mappings are mutable because of two APIs:
- Mapper.merge, which expects changes to be performed in-place
- IncludeInAll, which allows to change whether values should be put in the
`_all` field in place.
This commit changes both APIs to return a modified copy instead of modifying in
place so that mappings can be immutable. For now, only the type-level object is
immutable, but in the future we can imagine making them immutable at the
index-level so that mapping updates could be completely atomic at the index
level.
Close#9365
throw exception if a copy_to is within a multi field
Copy to within multi field is ignored from 2.0 on, see #10802.
Instead of just ignoring it, we should throw an exception if this
is found in the mapping when a mapping is added. For already
existing indices we should at least log a warning.
We remove the copy_to in any case.
related to #14946
Failures to merge a mapping can either come as a MergeMappingException if they
come from Mapper.merge or as an IllegalArgumentException if they come from
FieldTypeLookup.checkCompatibility. I think we should settle on one: this pull
request replaces all usage of MergeMappingException with
IllegalArgumentException.
Its enough to test the content type for what we are testing.
Currently tests are flaky if charset is detected as e.g. windows-1252 vs iso-8859-1 and so on.
In fact, they fail on windows 100% of the time.
We are not trying to test charset detection heuristics (which might be different even due to newlines in tests or other things).
If we want to do test that, we should test it separately.
This moves the registration of field mappers from the index level to the node
level and also ensures that mappers coming from plugins are treated no
differently from core mappers.
* Forbid System.setProperties & co in forbidden APIs.
* Ban property write access at runtime with security manager.
Plugins that need to modify system properties will need to request permission in their plugin-security.policy
Transitive dependencies can be confusing and hard to deal with when
conflicts arise between them. This change removes transitive
dependencies from elasticsearch, and forces any dependency conflicts to
be resolved manually, instead of automatically by gradle.
closes#14627
Some dependencies must be specified in a couple places in the build.
e.g. randomized runner is specified both in buildSrc (for the gradle
wrapper plugin), as well as in the test-framework.
This change creates buildSrc/versions.properties which acts similar to
the set of shared version properties we used to have in the maven parent
pom.
The documentation says we support EPUB, but the parser is not enabled.
This parser does not require any external dependencies, so I think its ok?
Separately, test-framework drags in an ancient commons-codec (via httpclient), which gradle
"upgrades", but IDEs can't handle this case and just hit jar hell. So just wire that to 1.9,
this allows running tests in the IDE for this plugin.
