Required also converting some of the transaction functions to WriteTxn
because TxnRO() called the same helper as TxnRW.
This change allows us to return a memdb.Txn for read-only txn instead of
wrapping them with state.txn.
This change was mostly automated with the following
First generate a list of functions with:
git grep -o 'Store) \([^(]\+\)(tx \*txn' ./agent/consul/state | awk '{print $2}' | grep -o '^[^(]\+'
Then the list was curated a bit with trial/error to remove and add funcs
as necessary.
Finally the replacement was done with:
dir=agent/consul/state
file=${1-funcnames}
while read fn; do
echo "$fn"
sed -i -e "s/(s \*Store) $fn(/$fn(/" $dir/*.go
sed -i -e "s/s\.$fn(/$fn(/" $dir/*.go
sed -i -e "s/s\.store\.$fn(/$fn(/" $dir/*.go
done < $file
The general problem was that a the CA config which contained the trust domain was happening outside of the blocking mechanism so if the client started the blocking query before the primary dcs roots had been set then a state trust domain was being pushed down.
This was fixed here but in the future we should probably fixup the CA initialization code to not initialize the CA config twice when it doesn’t need to.
* Support rate limiting and concurrency limiting CSR requests on servers; handle CA rotations gracefully with jitter and backoff-on-rate-limit in client
* Add CSR rate limiting docs
* Fix config naming and add tests for new CA configs
* Store leaf cert indexes in raft and use for the ModifyIndex on the returned certs
This ensures that future certificate signings will have a strictly greater ModifyIndex than any previous certs signed.
This PR both prevents a blank CA config from being written out to
a snapshot and allows Consul to gracefully recover from a snapshot
with an invalid CA config.
Fixes#4954.
