Rename processor now checks whether the field to rename exists and throws exception if it doesn't. It also checks that the new field to rename to doesn't exist yet, and throws exception otherwise. Also we make sure that the rename operation is atomic, otherwise things may break between the remove and the set and we'd leave the document in an inconsistent state.
Note that the requirement for the new field name to not exist simplifies the usecase for e.g. { "rename" : { "list.1": "list.2"} } as such a rename wouldn't be accepted if list is actually a list given that either list.2 already exists or the index is out of bounds for the existing list. If one really wants to replace an existing field, that field needs to be removed first through remove processor and then rename can be used.
1) It no longer extends from Closeable.
2) Removed the config directory setter. Implementation that relied on it, now get the location to the config dir via their constructors.
When reading, through #getFieldValue and #hasField, and a list is encountered, the next element in the path is treated as the index of the item that the path points to (e.g. `list.0.key`). If the index is not a number or out of bounds, an exception gets thrown.
Added #appendFieldValue method that has the same behaviour as setFieldValue, but when a list is the last element in the path, instead of replacing the whole list it will simply add a new element to the existing list. This method is currently unused, we have to decide whether the set processor or a new processor should use it.
A few other changes made:
- Renamed hasFieldValue to hasField, as this method is not really about values but only keys. It will return true if a key is there but its value is null, while it returns false only when a field is not there at all.
- Changed null semantic in getFieldValue. null gets returned only when it was an actual value in the source, an exception is thrown otherwise when trying to access a non existing field, so that null != field not present.
- Made remove stricter about non existing fields. Throws error when trying to remove a non existing field. This is more consistent with the other methods in IngestDocument which are strict about fields that are not present.
Relates to #14324
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.
The current delay waits until later after normal configuration, but
still just after resolution (ie when paths would be known for
dependencies but not actual execution). This delays the checks further
to be done right before we actually execute the copy task.
closes#15068
Currently if running with --info, the command line for ES, along with
env vars, are logged before they may be ammended to add debug options.
This moves the adding JAVA_OPTS to before we print the command.
Removed check that two query builder that are different according
to equals() have different hashCode since that is not required
by the contract of hashCode.
