Previously only a single auth method would be saved to the snapshot. This commit fixes the typo
and adds to the test, to show that all auth methods are now saved.
This PR replaces the original boolean used to configure transparent
proxy mode. It was replaced with a string mode that can be set to:
- "": Empty string is the default for when the setting should be
defaulted from other configuration like config entries.
- "direct": Direct mode is how applications originally opted into the
mesh. Proxy listeners need to be dialed directly.
- "transparent": Transparent mode enables configuring Envoy as a
transparent proxy. Traffic must be captured and redirected to the
inbound and outbound listeners.
This PR also adds a struct for transparent proxy specific configuration.
Initially this is not stored as a pointer. Will revisit that decision
before GA.
This is needed in case the client proxy is in TransparentProxy mode.
Typically they won't have explicit configuration for every upstream, so
this ensures the settings can be applied to all of them when generating
xDS config.
New clients in transparent proxy mode can send requests for service
config resolution without any upstream args because they do not have
explicitly defined upstreams.
Old clients on the other hand will never send requests without the
Upstreams args unless they don't have upstreams, in which case we do not
send back upstream config.
As part of this change the indexer will now be case insensitive by using
the lower case value. This should be safe because previously we always
had lower case strings.
This change was made out of convenience. All the other indexers use
lowercase, so we can re-use the indexFromQuery function by using
lowercase here as well.
Previously we were encoding the UUID as a string, but the index it references uses a UUID
so this index can also use an encoded UUID to save a bit of memory.
Prefix queries are generally being used to match part of a partial
index. We can support these indexes by using a function that accept
different types for each subset of the index.
What I found interesting is that in the generic StringFieldIndexer the
implementation for PrefixFromArgs would remove the trailing null, but
at least in these 2 cases we actually want a null terminated string.
We simply want fewer components in the string.
