Follow up of #22857 where we deprecate automatic creation of azure containers.
BTW I found that the `AzureSnapshotRestoreServiceIntegTests` does not bring any value because it runs basically a Snapshot/Restore operation on local files which we already test in core.
So instead of trying to fix it to make it pass with this PR, I simply removed it.
This commit adds a SpecialPermission constant and uses that constant
opposed to introducing new instances everywhere.
Additionally, this commit introduces a single static method to check that
the current code has permission. This avoids all the duplicated access
blocks that exist currently.
This is related to #22116. Certain plugins (discovery-azure-classic,
discovery-ec2, discovery-gce, repository-azure, repository-gcs, and
repository-s3) open socket connections. As SocketPermissions are
transitioned out of core, these plugins will require connect
permission. This pull request wraps operations that require these
permissions in doPrivileged blocks.
Before, the default chunk size for Azure repositories was
-1 bytes, which meant that if the chunk_size was not set on
the Azure repository, nor as a node setting, then no data
files would get written as part of the snapshot (because
the BlobStoreRepository's PartSliceStream does not know
how to process negative chunk sizes).
This commit fixes the default chunk size for Azure repositories
to be the same as the maximum chunk size. This commit also
adds tests for both the Azure and Google Cloud repositories to
ensure only valid chunk sizes can be set.
Closes#22513
Affix settings are useful to namespace a certain setting. Yet, affix settings
must be specialized for their concrete type which causes lot of code duplication.
This commit allows to reuse an existing setting with and affix setting as soon as
a concrete key is available.
* Remove a checked exception, replacing it with `ParsingException`.
* Remove all Parser classes for the yaml sections, replacing them with static methods.
* Remove `ClientYamlTestFragmentParser`. Isn't used any more.
* Remove `ClientYamlTestSuiteParseContext`, replacing it with some static utility methods.
I did not rewrite the parsers using `ObjectParser` because I don't think it is worth it right now.
While I was fixing a documentation issue (#22007), I looked at the code and discovered that we actually never read what the user entered as a `readonly` parameter when he creates an azure repository.
So if someone sends:
```
PUT _snapshot/my_backup4
{
"type": "azure",
"settings": {
"account": "my_account2",
"location_mode": "primary_only",
"readonly": true
}
}
```
The repository is not actually defined as `readonly`.
It's caused by the fact we are always overwriting `readonly`setting based on `location_mode`.
If a user sets it to `primary_only`, `readonly` is forced to `false`.
If a user sets it to `primary_then_secondary`, `readonly` is forced to `false`.
If a user sets it to `secondary_only`, `readonly` is forced to `false`.
Note that with this change, a user can force a `secondary_only` repository to `readonly: false` which will lead him to an error later on when we check the repository as per definition in Azure, a secondary repository is not writable.
Another option could have been to detect this mismatch and throw an exception in that case. Note sure it is worth writing more code though.
Closes#22053.
Group, List and Affix settings generate a bogus diff that turns the actual
diff into a string containing a json structure for instance:
```
"action" : {
"search" : {
"remote" : {
"" : "{\"my_remote_cluster\":\"[::1]:60378\"}"
}
}
}
```
which make reading the setting impossible. This happens for instance
if a group or affix setting is rendered via `_cluster/settings?include_defaults=true`
This change fixes the issue as well as several minor issues with affix settings that
where not accepted as valid setting today.
At one point in the past when moving out the rest tests from core to
their own subproject, we had multiple test classes which evenly split up
the tests to run. However, we simplified this and went back to a single
test runner to have better reproduceability in tests. This change
removes the remnants of that multiplexing support.
`LocalDiscovery` is a discovery implementation that uses static in memory maps to keep track of current live nodes. This is used extensively in our tests in order to speed up cluster formation (i.e., shortcut the 3 second ping period used by `ZenDiscovery` by default). This is sad as that mean that most of the test run using a different discovery semantics than what is used in production. Instead of replacing the entire discovery logic, we can use a similar approach to only shortcut the pinging components.
We were swallowing the original exception when creating a client with bad credentials.
So even in `TRACE` log level, nothing useful were coming out of it.
With this commit, it now prints:
```
[2016-09-27 15:54:13,118][ERROR][cloud.azure.storage ] [node_s0] can not create azure storage client: Storage Key is not a valid base64 encoded string.
```
Closes#20633.
Backport of #20669 for master branch (6.0)
conform with the requirements of the writeBlob method by
throwing a FileAlreadyExistsException if attempting to write
to a blob that already exists. This change means implementations
of BlobContainer should never overwrite blobs - to overwrite a
blob, it must first be deleted and then can be written again.
Closes#15579
This makes it obvious that these tests are for running the client yaml
suites. Now that there are other ways of running tests using the REST
client against a running cluster we can't go on calling the shared
client yaml tests "REST tests". They are rest tests, but they aren't
**the** rest tests.
This adds a header that looks like `Location: /test/test/1` to the
response for the index/create/update API. The requirement for the header
comes from https://www.w3.org/Protocols/rfc2616/rfc2616-sec10.htmlhttps://tools.ietf.org/html/rfc7231#section-7.1.2 claims that relative
URIs are OK. So we use an absolute path which should resolve to the
appropriate location.
Closes#19079
This makes large changes to our rest test infrastructure, allowing us
to write junit tests that test a running cluster via the rest client.
It does this by splitting ESRestTestCase into two classes:
* ESRestTestCase is the superclass of all tests that use the rest client
to interact with a running cluster.
* ESClientYamlSuiteTestCase is the superclass of all tests that use the
rest client to run the yaml tests. These tests are shared across all
official clients, thus the `ClientYamlSuite` part of the name.
In #15950#15080#16084 we added the support of TimeOut for Requests with a default client`setTimeoutIntervalInMs`.
So we can remove this useless todo which was added for only one method.
Closes#18617.
Azure and Google cloud blob containers, as the APIs for both return
a 404 in the case of a missing object, which we already handle through
a NoSuchFileFoundException.
Added BlobContainer tests for HDFS storage
and caught a bug at the same time in which
deleteBlob was not raising an IOException
when the blobName did not exist.
Added BlobContainer tests for Azure storage
and caught a bug at the same time in which
deleteBlob was not raising an IOException
when the blobName did not exist.
Repository plugins currently use a lot of custom classes like
RepositoryName and RepositorySettings in order to use guice to construct
repository implementations. But repositories now only really need their
settings to be constructed. Anything else they need (eg a cloud client)
can be constructed within the plugin, instead of via guice.
This change makes repository plugins use the new pull model. It removes
guice from the construction of Repository objects (no more child
injectors) and also from all repository plugins.
The api for snapshot/restore was split up between two interfaces,
Repository and IndexShardRepository. There was also complex
initialization and injection between the two. However, there is always a
one to one relationship between the two.
This change moves the IndexShardRepository api into Repository, as well
as updates the API so as not to require any services to be injected for
sublcasses.
The only reason for LifecycleComponent taking a generic type was so that
it could return that type on its start and stop methods. However, this
chaining has no practical necessity. Instead, start and stop can be
void, and a whole bunch of confusing generics disappear.
Before, a repository would maintain an index file (named 'index') per
repository, that contained the current snapshots in the repository.
This file was not atomically written, so repositories had to depend on
listing the blobs in the repository to determine what the current
snapshots are, and only rely on the index file if the repository does
not support the listBlobs operation. This could cause an incorrect view
of the current snapshots in the repository if any prior snapshot delete
operations failed to delete snapshot metadata files.
This commit introduces the atomic writing of the index file, and because
atomic writes are not guaranteed if the file already exists, we write to
a generational index file (index-N, where N is the current generation).
We also maintain an index-latest file that contains the current
generation, for those repositories that cannot list blobs.
Closes#19002

Raise IOException on deleteBlob if the blob doesn't exist
This commit raises an IOException on BlobContainer#deleteBlob
if the blob does not exist, in conformance with the BlobContainer
interface contract. Each implementation of BlobContainer now
conforms to this contract (file system, S3, Azure, HDFS). This
commit also contains blob container tests for each of the
repository implementations.
Closes#18530
Since the Settings infrastructure has been improved, a group setting must be registered by the repository-azure plugin to allow settings like "cloud.azure.storage.my_account.account" to be coherent with Azure plugin documentation.
We pretended to be able to ackt like a different version node for so long it's
time to be honest and remove this ability. It's just confusing and where needed
and tested we should build dedicated extension points.
Today we have a push model for registering basically anything. All our extension points
are defined on modules which we pass in to plugins. This is harder to maintain and adds
unnecessary dependencies on the modules itself. This change moves towards a pull model
where the plugin offers a getter kind of method to get the extensions. This will also
help in the future if we need to pass dependencies to the extension points which can
easily be defined on the method as arguments if a pull model is used.
In 2.0 we added plugin descriptors which require defining a name and
description for the plugin. However, we still have name() and
description() which must be overriden from the Plugin class. This still
exists for classpath plugins. But classpath plugins are mainly for
tests, and even then, referring to classpath plugins with their class is
a better idea. This change removes name() and description(), replacing
the name for classpath plugins with the full class name.

This PR changes the InternalTestCluster to support dedicated master nodes. The creation of dedicated master nodes can be controlled using a new `supportsMasterNodes` parameter to the ClusterScope annotation. If set to true (the default), dedicated master nodes will randomly be used. If set to false, no master nodes will be created and data nodes will also be allowed to become masters. If active, test runs will either have 1 or 3 masternodes

Probably when we updated Azure SDK, we introduced a regression.
Actually, we are not able to remove files anymore.
For example, if you register a new azure repository, the snapshot service tries to create a temp file and then remove it.
Removing does not work and you can see in logs:
```
[2016-05-18 11:03:24,914][WARN ][org.elasticsearch.cloud.azure.blobstore] [azure] can not remove [tests-ilmRPJ8URU-sh18yj38O6g/] in container {elasticsearch-snapshots}: The specified blob does not exist.
```
This fix deals with that. It now list all the files in a flatten mode, remove in the full URL the server and the container name.
As an example, when you are removing a blob which full name is `https://dpi24329.blob.core.windows.net/elasticsearch-snapshots/bar/test` you need to actually call Azure SDK with `bar/test` as the path, `elasticsearch-snapshots` is the container.
To run the test, you need to pass some parameters: `-Dtests.thirdparty=true -Dtests.config=/path/to/elasticsearch.yml`
Where `elasticsearch.yml` contains something like:
```
cloud.azure.storage.default.account: account
cloud.azure.storage.default.key: key
```
Related to #16472Closes#18436.
This commit removes the method Strings#splitStringToArray and replaces
the call sites with invocations to String#split. There are only two
explanations for the existence of this method. The first is that
String#split is slightly tricky in that it accepts a regular expression
rather than a character to split on. This means that if s is a string,
s.split(".") does not split on the character '.', but rather splits on
the regular expression '.' which splits on every character (of course,
this is easily fixed by invoking s.split("\\.") instead). The second
possible explanation is that (again) String#split accepts a regular
expression. This means that there could be a performance concern
compared to just splitting on a single character. However, it turns out
that String#split has a fast path for the case of splitting on a single
character and microbenchmarks show that String#split has 1.5x--2x the
throughput of Strings#splitStringToArray. There is a slight behavior
difference between Strings#splitStringToArray and String#split: namely,
the former would return an empty array in cases when the input string
was null or empty but String#split will just NPE at the call site on
null and return a one-element array containing the empty string when the
input string is empty. There was only one place relying on this behavior
and the call site has been modified accordingly.
Now that the current uses of magical camelCase support have been
deprecated, we can remove these in master (sans remaining issues like
BulkRequest). This change removes camel case support from ParseField,
query types, analysis, and settings lookup.
see #8988
We have both `Settings.settingsBuilder` and `Settings.builder` that do exactly
the same thing, so we should keep only one. I kept `Settings.builder` since it
has my preference but also it is the one that we use in examples of the Java API.
This change moves placeholder replacement to a pkg private class for
settings. It also adds a null check when calling replacement, as
settings objects can still contain null values, because we only prohibit
nulls on file loading. Finally, this cleans up file and stream loading a
bit to not have unnecessary exception wrapping.
We are using `2.0.0` today but Azure team now recommends:
```xml
<dependency>
<groupId>com.microsoft.azure</groupId>
<artifactId>azure-storage</artifactId>
<version>4.0.0</version>
</dependency>
```
This new version fix the timeout issues we have seen with azure storage although #15080 adds a timeout support.
Azure storage client 2.0.0 was not passing correctly this value when it was calling Azure services.
Note that the timeout is a server side timeout and not client side timeout.
It means that it will raise only a timeout when:
* upload of blob is complete
* if azure service is not able to process the blob (and store it) within a given time range.
In which case it will raise an exception which elasticsearch can deal with:

* Added support for "Create" permissions on Blob and File SAS.
* Added support for IP Restricted SAS and Protocol SAS.
* Added support for Account SAS to all services.
* Added support for Minute and Hour Metrics to FileServiceProperties and added support for File Metrics to CloudAnalyticsClient.
* Removed deprecated startCopyFromBlob() on CloudBlob. Use startCopy() instead.
* Removed deprecated Credentials and StorageKey classes. Please use the appropriate methods on StorageCredentialsAccountAndKey instead.
* Fixed a bug in table where a select on a non-existent field resulted in a null reference exception if the corresponding field in the TableEntity was not nullable.
* Fixed a bug in table where JsonParser was automatically closing the response stream before it was completely drained causing socket exhaustion.
* Fixed a bug in StorageCredentialsAccountAndKey.updateKey(String) which prevented valid keys from being set.
* Added CloudBlobContainer.listBlobs(final String, final boolean) method.
* Fixed a bug in blob where using AccessConditions on block blob uploads larger than 64MB done with the upload* methods or block blob uploads done openOutputStream with would fail if the blob did not already exist.
* Added support for setting a proxy per request. Proxy can be set on an OperationContext instance and will be used when that instance is passed to the request method.
* Added support for SAS to the Azure File service.
* Added support for Append Blob.
* Added support for Access Control Lists (ACL) to File Shares.
* Added support for getting and setting of CORS rules to File service.

* Added support for copying an Azure File to another Azure File or a Block Blob asynchronously, and aborting Azure File copy operations asynchronously.
* Added support for copying a Blob to an Azure File asynchronously.
* Added support for setting a maximum quota property on a File Share.
* Removed deprecated AuthenticationScheme and its getter and setter. In the future only SharedKey will be used.
* Removed deprecated getter/setters for all request option properties on the service clients. Please use the default request options getter/setters instead.
* Removed getSubDirectoryReference() for blob directories and file directories. Use getDirectoryReference() instead.
* Removed getEntityClass() in TableQuery. Please use getClazzType() instead.

* Added support for logging StringToSign to SharedKey and SAS.
* **Added a connect timeout to prevent hangs when establishing the network connection.**
* **Made performance enhancements to the BlobOutputStream class.**
* Fixed a bug where maximum execution time was ignored for file, queue, and table services.
* **Changed the socket timeout to be set to the service side timeout plus 5 minutes when maximum execution time is not set.**
* **Changed the socket timeout to default to 5 minutes rather than infinite when neither service side timeout or maximum execution time are set.**
* Fixed a bug where MD5 was calculated for commitBlockList even though UseTransactionalMD5 was set to false.
* Fixed a bug where selecting fields that did not exist returned an error rather than an EntityProperty with a null value.
* Fixed a bug where table entities with a single quote in their partition or row key could be inserted but not operated on in any other way.
* Fixed a bug for all listing API's where next() would sometimes throw an exception if hasNext() had not been called even if there were more elements to iterate on.
* Added sequence number to the blob properties. This is populated for page blobs.
* Creating a page blob sets its length property.
* Added support for page blob sequence numbers and sequence number access conditions.
* Fixed a bug in abort copy where the lease access condition was not sent to the service.
* Fixed an issue in startCopyFromBlob where if the URI of the source blob contained certain non-ASCII characters they would not be encoded appropriately. This would result in Authorization failures.
* Fixed a small performance issue in XML serialization.
* Fixed a bug in BlobOutputStream and FileOutputStream where flush added data to a request pool rather than immediately committing it to the Azure service.
* Refactored to remove the blob, queue, and file package dependency on table in the error handling code.
* Added additional client-side logging for REST requests, responses, and errors.
Closes#15976.
Instead of modifying methods each time we need to add a new behavior for settings, we can simply pass `SettingsProperty... properties` instead.
`SettingsProperty` could be defined then:
```
public enum SettingsProperty {
Filtered,
Dynamic,
ClusterScope,
NodeScope,
IndexScope
// HereGoesYours;
}
```
Then in setting code, it become much more flexible.
TODO: Note that we need to validate SettingsProperty which are added to a Setting as some of them might be mutually exclusive.
Removes all our logger wrappers except the wrapper for log4j1.2. If you
depend on Elasticsearch's jar in your application you'll need to declare
log4j 1.2 and/or some bridge to your favorite logger.
We did this to simplify our builds and code. No more commons-logging like
log implementation sniffing. No more optional dependency hacks in gradle.
We might one day want to use j.u.l instead of log4j. If we do want that
we can recover its wrapper by studying this commit. We didn't go directly
to j.u.l in this commit because that is a bigger change. Our logging
configuration is based on log4j1.2 and people are used to it. So it'd
be a much more fraught breaking change to do that conversion.
Now we have a nice Setting infra, we can define in Setting class if a setting should be filtered or not.
So when we register a setting, setting filtering would be automatically done.
Instead of writing:
```java
Setting<String> KEY_SETTING = Setting.simpleString("cloud.aws.access_key", false, Setting.Scope.CLUSTER);
settingsModule.registerSetting(AwsEc2Service.KEY_SETTING, false);
settingsModule.registerSettingsFilterIfMissing(AwsEc2Service.KEY_SETTING.getKey());
```
We could simply write:
```java
Setting<String> KEY_SETTING = Setting.simpleString("cloud.aws.access_key", false, Setting.Scope.CLUSTER, true);
settingsModule.registerSettingsFilterIfMissing(AwsEc2Service.KEY_SETTING.getKey());
```
It also removes `settingsModule.registerSettingsFilterIfMissing` method.
The plan would be to remove as well `settingsModule.registerSettingsFilter` method but it still used with wildcards. For example in Azure Repository plugin:
```java
module.registerSettingsFilter(AzureStorageService.Storage.PREFIX + "*.account");
module.registerSettingsFilter(AzureStorageService.Storage.PREFIX + "*.key");
```
Closes#16598.
This change rewrites the entire settings filtering mechanism to be immutable.
All filters must be registered up-front in the SettingsModule. Filters that are comma-sparated are
not allowed anymore and check on registration.
This commit also adds settings filtering to the default settings recently added to ensure we don't render
filtered settings.
This commit enableds strict settings validation on node startup. All settings
passed to elasticsearch either through system properties, yaml files or any other
way to pass settings must be registered and valid. Settings that are unknown ie. due to
typos or due to deprecation or removal will cause the node to NOT start up. Plugins
have to declare all their settings on the `SettingsModule#registerSetting` and settings for
plugins that are not installed must be removed.
This commit also removes the ability to specify the nodes name via `-Des.name` or just `name` in the
configuration files. The node name must be prefixed with the node prexif like `node.name: Boom`. Left over
usage of `name` will also cause startup to fail.
One test we forgot in #14843 and #13779 is the default client selection.
Most of the time, users won't define explicitly which client they want to use because they are providing only one connection to Azure storage:
```yml
cloud:
azure:
storage:
my_account:
account: your_azure_storage_account
key: your_azure_storage_key
```
Then using the default client like this:
```sh
# This one will use the default account (my_account1)
curl -XPUT localhost:9200/_snapshot/my_backup1?pretty -d '{
"type": "azure"
}'
```
This commit adds tests to check that the right client is still selected when no client is explicitly set when creating the snapshot.
This commit replaces server side timeout (which is BTW not correctly implemented in azure client 2.0.0 but fixed later #16084) with a client side timeout.
As a consequence, for each request sent to azure, azure client will raise an exception after a given amount of time (timeout).
Closes#12567
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.
closes#15459
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.
Using a single azure account is now rejected.
This commit fixes this issue and adds a test for it.
This regression was introduced with #13779. Hopefully no elasticsearch version has been released since then.

declaring serialVersionUID on any classes that we make that happen to extend
Serializable.
3. Remove Serializable and serialVersionUID declarations.
I didn't use forbidden apis because it doesn't look like it has a way to ban
explicitly implementing Serializable. If you try to ban Serializable with
forbidden apis you end up banning all Exceptions and all Strings.
Closes#15847
By default, azure does not timeout. This commit adds support for a timeout settings which defaults to 5 minutes.
It's a timeout **per request** not a global timeout for a snapshot request.
It can be defined globally, per account or both. Defaults to `5m`.
```yml
cloud:
azure:
storage:
timeout: 10s
my_account1:
account: your_azure_storage_account1
key: your_azure_storage_key1
default: true
my_account2:
account: your_azure_storage_account2
key: your_azure_storage_key2
timeout: 30s
```
In this example, timeout will be 10s for `my_account1` and 30s for `my_account2`.
Closes#14277.
All those repository settings can also be defined globally in `elasticsearch.yml` file using prefix `repositories.azure.`. For example:
```yml
repositories.azure:
container: backup-container
base_path: backups
chunk_size: 32m
compress": true
```
Closes#13776.
Bug introduced in #13779: we don't filter anymore credentials because we were filtering `cloud.azure.storage.account` and `cloud.azure.storage.key` but now credentials are like `cloud.azure.storage.XXX.account` and `cloud.azure.storage.XXX.key` where `XXX` can be a storage setting id.
Closes#14843.
We actually want to keep the test when using deprecated setting in 3.0.
We will keep this setting deprecated as well so people will be able to update in a smoother way.
Also add the deprecating information to the migration documentation.
Follow up for #13228.
This commit adds support for a secondary storage account:
```yml
cloud:
azure:
storage:
my_account1:
account: your_azure_storage_account1
key: your_azure_storage_key1
default: true
my_account2:
account: your_azure_storage_account2
key: your_azure_storage_key2
```
When creating a repository, you can choose which azure account you want to use for it:
```sh
curl -XPUT localhost:9200/_snapshot/my_backup1?pretty -d '{
"type": "azure"
}'
curl -XPUT localhost:9200/_snapshot/my_backup2?pretty -d '{
"type": "azure",
"settings": {
"account" : "my_account2",
"location_mode": "secondary_only"
}
}'
```
`location_mode` supports `primary_only` or `secondary_only`. Defaults to `primary_only`. Note that if you set it
to `secondary_only`, it will force `read_only` to true.
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.

`AbstractLegacyBlobContainer` was kept for historical reasons (see #13434).
We can migrate Azure and S3 repositories to use the new methods added in #13434 so we can remove `AbstractLegacyBlobContainer` class.
This change removes the leftover pom files. A couple files were left for
reference, namely in qa tests that have not yet been migrated (vagrant
and multinode). The deb and rpm assemblies also still exist for
reference when finishing their setup in gradle.
See #13930
There are three ways `@Test` was used. Way one:
```java
@Test
public void flubTheBlort() {
```
This way was always replaced with:
```java
public void testFlubTheBlort() {
```
Or, maybe with a better method name if I was feeling generous.
Way two:
```java
@Test(throws=IllegalArgumentException.class)
public void testFoo() {
methodThatThrows();
}
```
This way of using `@Test` is actually pretty OK, but to get the tools to ban
`@Test` entirely it can't be used. Instead:
```java
public void testFoo() {
try {
methodThatThrows();
fail("Expected IllegalArgumentException");
} catch (IllegalArgumentException e ) {
assertThat(e.getMessage(), containsString("something"));
}
}
```
This is longer but tests more than the old ways and is much more precise.
Compare:
```java
@Test(throws=IllegalArgumentException.class)
public void testFoo() {
some();
copy();
and();
pasted();
methodThatThrows();
code(); // <---- This was left here by mistake and is never called
}
```
to:
```java
@Test(throws=IllegalArgumentException.class)
public void testFoo() {
some();
copy();
and();
pasted();
try {
methodThatThrows();
fail("Expected IllegalArgumentException");
} catch (IllegalArgumentException e ) {
assertThat(e.getMessage(), containsString("something"));
}
}
```
The final use of test is:
```java
@Test(timeout=1000)
public void testFoo() {
methodThatWasSlow();
}
```
This is the most insidious use of `@Test` because its tempting but tragically
flawed. Its flaws are:
1. Hard and fast timeouts can look like they are asserting that something is
faster and even do an ok job of it when you compare the timings on the same
machine but as soon as you take them to another machine they start to be
invalid. On a slow VM both the new and old methods fail. On a super-fast
machine the slower and faster ways succeed.
2. Tests often contain slow `assert` calls so the performance of tests isn't
sure to predict the performance of non-test code.
3. These timeouts are rude to debuggers because the test just drops out from
under it after the timeout.
Confusingly, timeouts are useful in tests because it'd be rude for a broken
test to cause CI to abort the whole build after it hits a global timeout. But
those timeouts should be very very long "backstop" timeouts and aren't useful
assertions about speed.
For all its flaws `@Test(timeout=1000)` doesn't have a good replacement __in__
__tests__. Nightly benchmarks like http://benchmarks.elasticsearch.org/ are
useful here because they run on the same machine but they aren't quick to check
and it takes lots of time to figure out the regressions. Sometimes its useful
to compare dueling implementations but that requires keeping both
implementations around. All and all we don't have a satisfactory answer to the
question "what do you replace `@Test(timeout=1000)`" with. So we handle each
occurrence on a case by case basis.
For files with `@Test` this also:
1. Removes excess blank lines. They don't help anything.
2. Removes underscores from method names. Those would fail any code style
checks we ever care to run and don't add to readability. Since I did this manually
I didn't do it consistently.
3. Make sure all test method names start with `test`. Some used to end in `Test` or start
with `verify` or `check` and they were picked up using the annotation. Without the
annotation they always need to start with `test`.
4. Organizes imports using the rules we generate for Eclipse. For the most part
this just removes `*` imports which is a win all on its own. It was "required"
to quickly remove `@Test`.
5. Removes unneeded casts. This is just a setting I have enabled in Eclipse and
forgot to turn off before I did this work. It probably isn't hurting anything.
6. Removes trailing whitespace. Again, another Eclipse setting I forgot to turn
off that doesn't hurt anything. Hopefully.
7. Swaps some tests override superclass tests to make them empty with
`assumeTrue` so that the reasoning for the skips is logged in the test run and
it doesn't "look like" that thing is being tested when it isn't.
8. Adds an oxford comma to an error message.
The total test count doesn't change. I know. I counted.
```bash
git checkout master && mvn clean && mvn install | tee with_test
git no_test_annotation master && mvn clean && mvn install | tee not_test
grep 'Tests summary' with_test > with_test_summary
grep 'Tests summary' not_test > not_test_summary
diff with_test_summary not_test_summary
```
These differ somewhat because some tests are skipped based on the random seed.
The total shouldn't differ. But it does!
```
1c1
< [INFO] Tests summary: 564 suites (1 ignored), 3171 tests, 31 ignored (31 assumptions)
---
> [INFO] Tests summary: 564 suites (1 ignored), 3167 tests, 17 ignored (17 assumptions)
```
These are the core unit tests. So we dig further:
```bash
cat with_test | perl -pe 's/\n// if /^Suite/;s/.*\n// if /IGNOR/;s/.*\n// if /Assumption #/;s/.*\n// if /HEARTBEAT/;s/Completed .+?,//' | grep Suite > with_test_suites
cat not_test | perl -pe 's/\n// if /^Suite/;s/.*\n// if /IGNOR/;s/.*\n// if /Assumption #/;s/.*\n// if /HEARTBEAT/;s/Completed .+?,//' | grep Suite > not_test_suites
diff <(sort with_test_suites) <(sort not_test_suites)
```
The four tests with lower test numbers are all extend `AbstractQueryTestCase`
and all have a method that looks like this:
```java
@Override
public void testToQuery() throws IOException {
assumeTrue("test runs only when at least a type is registered", getCurrentTypes().length > 0);
super.testToQuery();
}
```
It looks like this method was being double counted on master and isn't anymore.
Closes#14028
Until now we had a cloud-azure plugin which is providing 3 distinct features:
* discovery on Azure
* snapshot/restore on Aure
* SMB store
This commit splits the plugin by feature so people can use either one or the other or both features.
Doc is updated accordingly.
