this commit also fixes a bug where we wramed a leaf reader in a top level context
which caused atomic segment readers to be used in our top level caches.
IndexReader#addReaderCloseListener is very error prone when it comes to
caching and reader wrapping. The listeners are not delegated to the sub readers
nor can it's implementation change since it's final in the base class. This commit
only allows installing close listeners on the top level ElasticsearchDirecotryReader
which is known to work an has a defined lifetime which corresponds to its subreader.
This ensure that cachesa re cleared once the reader goes out of scope.
In #13606, the ability to exclude a template from being wiped was added but a call to
wipeTemplates() was not removed, so all index templates were still being removed.
This change removes the wipeTemplates() call in the wipe method so that only the
non-excluded templates are removed.
Depending on how elasticsearch is installed, we have two scenarios to take into account that relate to user, group and permissions assigned to the config directory:
1) deb/rpm package: /etc/elasticsearch is root:elasticsearch 750 and the plugin script is run from root user
2) tar/zip archive: es config dir is most likely elasticsearch:elasticsearch and the plugin script is most likely run from elasticsearch user
When the plugin script copies over the plugin config dir within the es config dir, it should take care of setting the proper user, group and permissions, which vary depending on how elasticsearch was installed in the first place. Should be root:elasticsearch 750 if installed from a package, or elasticsearch:elasticsearch if installed from an archive.
This commit makes sure that the plugin script looks at user, group and permissions of the config dir and copies them over to the plugin config subdirectory, whatever they are, so that they get properly setup depending on how elasticsearch was installed in the first place. We also make sure that execute permissions are left untouched for files.

make the version map cache per-segment
This commit adds methods to serialize the elements of int and long
arrays using variable-length encodings. This can be useful for
serializing int and long arrays containing mostly non-negative “not
large” values in a compressed form.
FiltersFunctionScoreQuery sums up scores and weights and scores as double but when
we explain we cannot get the double scores from the explanation of score
functions. as a result we cannot compute the exact score from the explanations
of the functions alone.
this commit makes the explanation more accurate but also causes the score to be
computed one additional time.
we should sum the weights as double to not lose precision. also,
the tests should simulate exactly what function score does and then test
for equality of scores.
This method is unused can can simply be removed. It's rather confusing
instead since it's another way of invalidating a cache entry but not through
the close listener.
Restoring an index from a snapshot or creating a new index can bring the index settings index.blocks.read_only, index.blocks.read, index.blocks.write and index.blocks.metadata out-of-sync with the corresponding cluster blocks.
Closes#13931
The IndexAliasesService abstraction only adds unnecessary code and classes
and can be removed. This commit folds the rather simple methods in this
class into IndexService where the IndexAliasesService was obtained from in the past.
This commit upgrades mustache.java to version 0.9.1. The primary motive
for this is because version 0.8.13 depends on Guava, but version 0.9.1
does not.
