* Strip empty strings from database revocation stmts
It's technically valid to give empty strings as statements to run on
most databases. However, in the case of revocation statements, it's not
only generally inadvisable but can lead to lack of revocations when you
expect them. This strips empty strings from the array of revocation
statements.
It also makes two other changes:
* Return statements on read as empty but valid arrays rather than nulls,
so that typing information is inferred (this is more in line with the
rest of Vault these days)
* Changes field data for TypeStringSlice and TypeCommaStringSlice such
that a client-supplied value of `""` doesn't turn into `[]string{""}`
but rather `[]string{}`.
The latter and the explicit revocation statement changes are related,
and defense in depth.
With vault-1.0.0 and vault-0.11.4 a different path is needed to list the jwt registered roles:
```
$ vault list auth/jwt/roles
No value found at auth/jwt/roles/
$ vault list auth/jwt/role
Keys
----
myrole
```
I hope this helps!
This PR fix#5778.
Easy test case to reproduce the problem:
https://play.golang.org/p/CAMdrOHT7C1
Since `certStr` is empty string during first iteration `strings.Join()`
will merge empty line with first CA cert.
Extra `strings.TrimSpace` call will remove that empty line, before
certificate will be return.
The docs hadn't been updated to reflect the ability to do cross-account
AWS IAM auth, and so it was a bit confusing as to whether that was
supported. This removes the ambiguity by explicitly mentioning AWS IAM
principals.
* Remove DEL characters from password input
iTerm password manager sends \x03\0x7f before sending a password
from its password manager to make sure the password is not being
echoed to the screen. Unfortunately, vault login does not handle
the Space DEL sequence, causing the login to fail when using the
password manager. This patch uses a simple method to delete the
sequence if present anywhere in the string, although it is strictly
only needed at the start of input.
* Simplify iTerm handling to only remove iTerm prefix
The logic now only removes the two byte prefix sent in by iTerm
instead of trying to remove all deletes in the string.
This has been tested to work with the iTerm password manager.
As a small correction, the byte sequence is \x20\x7f. The
earlier commit message incorrectly stated it was \x03\x7f.
Documented changes from https://github.com/hashicorp/vault-plugin-auth-gcp/pull/55
* Deprecating `project_id` for `bound_projects` and making it optional
* Deprecating `google_certs_endpoint` (unused)
* Adding group aliases
Also, some general reformatting
