* Redo the API client quite a bit to make the behavior of NewClient more
predictable and add locking to make it safer to use with Clone() and if
multiple goroutines for some reason decide to change things.
Along the way I discovered that currently, the x/net/http2 package is
broke with the built-in h2 support in released Go. For those using
DefaultConfig (the vast majority of cases) this will be a non-event.
Others can manually call http2.ConfigureTransport as needed. We should
keep an eye on commits on that repo and consider more updates before
release. Alternately we could go back revisions but miss out on bug
fixes; my theory is that this is not a purposeful break and I'll be
following up on this in the Go issue tracker.
In a few tests that don't use NewTestCluster, either for legacy or other
reasons, ensure that http2.ConfigureTransport is called.
* Use tls config cloning
* Don't http2.ConfigureServer anymore as current Go seems to work properly without requiring the http2 package
* Address feedback
* Set number of pester retries to zero by default and make seal command return 403 if unauthorized instead of 500
* Fix build
* Use 403 instead and update test
* Change another 500 to 403
This should help with transient issues. Full control over min/max delays
and number of retries (and ability to turn off) is provided in the API
and via env vars.
Fix tests.
This allows the same environment variables to be read, parsed, and used
from any API client as was previously handled in the CLI. The CLI now
uses the API environment variable reading capability, then overrides any
values from command line flags, if necessary.
Fixes#618
This strips out http.DefaultClient everywhere I could immediately find
it. Too many things use it and then modify it in incompatible ways.
Fixes#700, I believe.
Vault doesn't generate these, but in some cases Go's internal HTTP
handler does. For instance, during a mount-tune command, finishing the
mount path with / (as in secret/) would cause the final URL path to
contain .../mounts/secret//tune. The double slash would trigger this
behavior in Go's handler and generate a 301. Since Vault generates 307s,
this would cause the client to think that everything was okay when in
fact nothing had happened.
create our own. This avoids some potential client race conditions when
they are setting values on the Vault API client while the default client
is being used elsewhere in other goroutines, as was seen in
consul-template.
