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.
`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.
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.
