This patch moves the Invokable Parameter cache to Reflection2 and adds
a convenience method for it to allow it to be shared by multiple
callers. The subsequent ability of S3Utils to use this cache results
in a ~40% improvement in performance for generating signed GETs and
PUTs for S3. This commit also converts a few others calls to
Invokable.getParameters() but the observed benefit from those was
small in microbenchmarks.
Atmos does not return a location header when writing zero-length
objects, which normally throws an HttpResponseException: no uri in
headers or content.
BlobStore.createContainerInLocation is supposed to return True if the
container was newly created and False if the container already
existed. This commit makes that happen for Swift blobstores.
So there were a few problems, but the core ugly one is that what you
pass in for creating a rule allowing groups' access is not the same
thing you get back from a group with such a rule, which makes mapping
between the arguments and the output insanely painful. So now, well,
we do some insanely painful stuff.
Involves some non-trivial reworking of EC2 security group
translation/binding, but it was necessary.
Still problems with a number of tests:
- org.jclouds.aws.ec2.compute.AWSEC2TemplateBuilderLiveTest#testTemplateBuilderWithLessRegions
- org.jclouds.ec2.compute.EC2TemplateBuilderLiveTest#testTemplateBuilderCanUseImageIdWithoutFetchingAllImages
Those seem to be failing because there's caching going on that they're
not expecting, but I could be wrong.
Also failing:
- org.jclouds.aws.ec2.features.PlacementGroupApiLiveTest in general
- org.jclouds.aws.ec2.features.SpotInstanceApiLiveTest - a couple tests
This removes
org.jclouds.ec2.compute.functions.PasswordCredentialsFromWindowsInstanceLiveTest
due to there not being an easily detectable valid AMI for it to run,
and low interest in actually running it in the first place.
Not all S3-compatible providers support virtual host buckets and thus
we should disable this feature by default. Continue to enable virtual
host buckets for AWS-S3 which supports this although this feature
suffers from DNS settling issues. Ran ran integration tests against
AWS-S3 and Scality using its S3 API.
By caching the results from Invokable.getParameters(), this commit
improves request signing performance (GETs and PUTs) for S3 by >
3X. These performance problems were seen in production and diagnosed
using the YourKit profiler.
Previously this test downloaded 45 MB in 30 seconds which failed on
slower connections, causing spurious test failures. The larger input
size provides no benefit.
