Running every test with the race detector would add significant time to
CI. That additionaltime won't provide much value as many of the integration tests use
much of the same code.
For now we can run -race on some of the smaller packages. As we move
more code into smaller packages we should be able to add more packages
to the list that runs with '-race'.
For now this is running without parallelism, but we can enable that as
well when we need it.
boltdb fails the 'checkptr' check, which is automatically enabled by
'-race', so I've disabled checkptr as well.
* Add uri identifiers to all data source things and make them the same
1. Add uri identitifer to data-source service
2. Make <EventSource /> and <DataSource /> as close as possible
3. Add extra `.closed` method to get a list of inactive/closed/closing
data-sources from elsewhere
* Make the connections cleanup the least worst connection when required
* Pass the uri/request id through all the things
* Better user erroring
* Make event sources close on error
* Allow <DataLoader /> data slot to be configurable
* Allow the <DataWriter /> removed state to be configurable
* Don't error if meta is undefined
* Stitch together all the repositories into the data-source/sink
* Use data.source over repositories
* Add missing <EventSource /> components
* Fix up the views/templates
* Disable all the old route based blocking query things
* We still need the repo for the mixin for the moment
* Don't default to default, default != ''
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
Making these functions allows them to be used without introducing
an artificial dependency on the struct. Many of these will be called
from streaming Event processors, which do not have a store.
This change is being made ahead of the streaming work to get to reduce
the size of the streaming diff.
Move the subscription context to Next. context.Context should generally
never be stored in a struct because it makes that struct only valid
while the context is valid. This is rarely obvious from the caller.
Adds a forceClosed channel in place of the old context, and uses the new
context as a way for the caller to stop the Subscription blocking.
Remove some recursion out of bufferImte.Next. The caller is already looping so we can continue
in that loop instead of recursing. This ensures currentItem is updated immediately (which probably
does not matter in practice), and also removes the chance that we overflow the stack.
NextNoBlock and FollowAfter do not need to handle bufferItem.Err, the caller already
handles it.
Moves filter to a method to simplify Next, and more explicitly separate filtering from looping.
Also improve some godoc
Only unwrap itemBuffer.Err when necessary
EventPublisher was receiving TopicHandlers, which had a couple of
problems:
- ChangeProcessors were being grouped by Topic, but they completely
ignored the topic and were performed on every change
- ChangeProcessors required EventPublisher to be aware of database
changes
By moving ChangeProcesors out of EventPublisher, and having Publish
accept events instead of changes, EventPublisher no longer needs to
be aware of these things.
Handlers is now only SnapshotHandlers, which are still mapped by Topic.
Also allows us to remove the small 'db' package that had only two types.
They can now be unexported types in state.
The EventPublisher is the central hub of the PubSub system. It is toughly coupled with much of
stream. Some stream internals were exported exclusively for EventPublisher.
The two Subscribe cases (with or without index) were also awkwardly split between two packages. By
moving EventPublisher into stream they are now both in the same package (although still in different files).
Also store the index in Changes instead of the Txn.
This change is in preparation for movinng EventPublisher to the stream package, and
making handleACLUpdates async once again.
It is critical that Unsubscribe be called with the same pointer to a
SubscriptionRequest that was used to create the Subscription. The
docstring made that clear, but it sill allowed a caler to get it wrong by
creating a new SubscriptionRequest.
By hiding this detail from the caller, and only exposing an Unsubscribe
method, it should be impossible to fail to Unsubscribe.
Also update some godoc strings.
Use a separate lock for subscriptions.ByToken to allow it to happen synchronously
in the commit flow.
This removes the need to create a new txn for the goroutine, and removes
the need for EventPublisher to contain a reference to DB.
Many of the fields are only needed in one place, and by using a closure
they can be removed from the struct. This reduces the scope of the variables
making it esier to see how they are used.
Otherwise the test will run with exactly the same values each time.
By printing the seed we can attempt to reproduce the test by adding an env var to override the seed
Make topicRegistry use functions instead of unbound methods
Use a regular memDB in EventPublisher to remove a reference cycle
Removes the need for EventPublisher to use a store
