We don't want to expose `String#getBytes` which is required for
`Base64.getEncoder.encode` to work because we're worried about
character sets. This adds `encodeBase64` and `decodeBase64`
methods to `String` in Painless that are duals of one another
such that:
`someString == someString.encodeBase64().decodeBase64()`.
Both methods work with the UTF-8 encoding of the string.
Closes#22648
Everything that extended `AbstractAsyncBulkByScrollAction` also
extended `AbstractAsyncBulkIndexByScrollAction` so this removes
`AbstractAsyncBulkIndexByScrollAction`, merging it into
`AbstractAsyncBulkByScrollAction`.
Changes the error message when `action.auto_create_index` or
`index.mapper.dynamic` forbids automatic creation of an index
from `no such index` to one of:
* `no such index and [action.auto_create_index] is [false]`
* `no such index and [index.mapper.dynamic] is [false]`
* `no such index and [action.auto_create_index] contains [-<pattern>] which forbids automatic creation of the index`
* `no such index and [action.auto_create_index] ([all patterns]) doesn't match`
This should make it more clear *why* there is `no such index`.
Closes#22435
Today we do not preserve response headers if they are present on a transport protocol
response. While preserving these headers is not always desired, in the most cases we
should pass on these headers to have consistent results for depreciation headers etc.
yet, this hasn't been much of a problem since most of the deprecations are detected early
ie. on the coordinating node such that this bug wasn't uncovered until #22647
This commit allow to optionally preserve headers when a context is restored and also streamlines
the context restore since it leaked frequently into the callers thread context when the callers
context wasn't restored again.
Instead of forcing each task to register all nodes where its children are running, this commit runs cancellation on all nodes. The task cancellation operation doesn't run too frequently, so this optimization doesn't seem to be worth additional complexity of the interface.
Previously, certain settings that could take multiple comma delimited
values would pick up incorrect values for all entries but the first if
each comma separated value was followed by a whitespace character. For
example, the multi-value "A,B,C" would be correctly parsed as
["A", "B", "C"] but the multi-value "A, B, C" would be incorrectly parsed
as ["A", " B", " C"].
This commit allows a comma separated list to have whitespace characters
after each entry. The specific settings that were affected by this are:
cluster.routing.allocation.awareness.attributes
index.routing.allocation.require.*
index.routing.allocation.include.*
index.routing.allocation.exclude.*
cluster.routing.allocation.require.*
cluster.routing.allocation.include.*
cluster.routing.allocation.exclude.*
http.cors.allow-methods
http.cors.allow-headers
For the allocation filtering related settings, this commit also provides
validation of each specified entry if the filtering is done by _ip,
_host_ip, or _publish_ip, to ensure that each entry is a valid IP
address.
Closes#22297
This commit tries to simplify the way ElasticsearchException are rendered to xcontent. It adds some documentation and renames and merges some methods. Current behavior is preserved, the goal is to be more readable and centralize everything in the ElasticsearchException class.
Today we have quite some abstractions that are essentially providing a simple
dispatch method to the plugins defining a `HttpServerTransport`. This commit
removes `HttpServer` and `HttpServerAdaptor` and introduces a simple `Dispatcher` functional
interface that delegate to `RestController` by default.
Relates to #18482
The IndexingOperationListener interface did not provide any
information about the shard id when a document was indexed.
This commit adds the shard id as the first parameter to all methods
in the IndexingOperationListener.
This is related to #22116. netty channels require socket `connect` and
`accept` privileges. Netty does not currently wrap these operations
with `doPrivileged` blocks. These changes extend the netty channels
and wrap calls to the relevant super methods in doPrivileged blocks.
Adds a message about how the remote is unlikely to be Elasticsearch.
This isn't as good as including the whole message from the remote but
we can't do that because we are stream parsing it and we don't want
to mark the whole request.
Closes#22330
Moves fetching the local node id into `NodeClient` which is a
fairly useful place to put it so you can generate task ids from
`NodeClient#executeLocally`.
It is no longer needed. It used to contain a lot of strings
used by serialization but those have since been removed. Now
it is just another thing to pass around that we don't really
need.
Reindex-from-remote had a race when it tried to clear the scroll. It
first starts the request to clear the scroll and then submits a task
to the generic threadpool to shutdown the client. These two things
race and, in my experience, closing the scroll generally loses. That
means that most of the time reindex-from-remote isn't clearing the
scrolls that it uses. This isn't the end of the world because we
flush old scroll contexts after a while but this isn't great.
Noticed while experimenting with #22514.
Reindex-from-remote was accepting source filtering in the request
but ignoring it and setting `_source=true` on the search URI. This
fixes the filtering so it is piped through to the remote node and
adds tests for that.
Closes#22507
Removes `AggregatorParsers`, replacing all of its functionality with
`XContentParser#namedObject`.
This is the third bit of payoff from #22003, one less thing to pass
around the entire application.
If the remote doesn't return a content type then reindex
tried to guess the content-type. This didn't work most
of the time and produced a rather useless error message.
Given that Elasticsearch always returns the content-type
we are dropping content-type detection in favor of just
failing the request if the remote didn't return a content-type.
Closes#22329
1. Escape sequences we're working. For example `\\` is now correctly
interpreted as `\` instead of `\\`. Same with `\'` being `'` and
`\"` being `"`.
2. `'` delimited strings weren't allowed to contain `"`s but it looked
like they were intended to support it. Now they do.
3. Improves the error message when the script contains an invalid
escape sequence inside a string to include a list of the valid
escape sequences.
Closes#22372
This integrates the mocksocket jar with elasticsearch tests. Mocksocket wraps actions requiring SocketPermissions in doPrivilege blocks. This will eventually allow SocketPermissions to be assigned to the mocksocket jar opposed to the entire elasticsearch codebase.
We previously named the thread using a frame from the stack trace, but
this was removed to simplify the code here. However, the comment
explaining this was left behind and this commit cleans that up.
