This change addresses an issue where deep paths would not be enumerated if parent paths did not contain a key.
Given the keys `shallow` and `deep` at the following paths...
```
secret/shallow
secret/path/deep
```
... a `LIST` request against `/v1/secret` would produce only one result, `shallow`. With this change, the same list request will now list `shallow` and `path/`.
* Add a benchmark for exiration.Restore
* Add benchmarks for consul Restore functions
* Add a parallel version of expiration.Restore
* remove debug code
* Up the MaxIdleConnsPerHost
* Add tests for etcd
* Return errors and ensure go routines are exited
* Refactor inmem benchmark
* Add s3 bench and refactor a bit
* Few tweaks
* Fix race with waitgroup.Add()
* Fix waitgroup race condition
* Move wait above the info log
* Add helper/consts package to store consts that are needed in cyclic packages
* Remove not used benchmarks
S3 results require paging to ensure that all results are returned. This
PR changes the S3 physical backend to use the new ListObjectV2 method
and pages through all the results.
Fixes#2223.
This patch fixes two bugs in Zookeeper backends:
* backend was determining if the node is a leaf or not basing on the number
of the childer given node has. This is incorrect if you consider the fact
that deleteing nested node can leave empty prefixes/dirs behind which have
neither children nor data inside. The fix changes this situation by testing
if the node has any data set - if not then it is not a leaf.
* zookeeper does not delete nodes that do not have childern just like consul
does and this leads to leaving empty nodes behind. In order to fix it, we
scan the logical path of a secret being deleted for empty dirs/prefixes and
remove them up until first non-empty one.
Current tests were not checking if backends are properly removing
nested secrets. We follow here the behaviour of Consul backend, where
empty "directories/prefixes" are automatically removed by Consul itself.
