Mike Gerwitz 9eb1f3afca DeltaProcessor: Correct delta application
Deltas must be applied in reverse to reproduce the state of the bucket or
rate data at that point in time, which is then paired with the delta that
will transform it into the previous state.

Mike Gerwitz 819701eca3 DeltaProcessor: Encapsulate getDeltas and remove redundant tests
getDeltas should be encapsulated.  It looks like it was public for the sake
of the tests, and its behavior can be inferred by looking at the result of
processing.
2019-12-12 10:27:09 -05:00
Mike Gerwitz d0a3ba573f DeltaProcessor: Remove redundant tests
These are covered by other tests and are testing too closely to the
implementation.  This should be encapsulated within the processor.

Austin Schaffer d9ee999adb [DEV-5312] Refactor class dependencies
Move create config functions out of the main delta-processor.ts file. Change some any types to more specific types. Define document structure better. Move prometheus logic out of processor class. Do not call logger directly, listen for events and log them. Change logger to more PSR-3 compliant style. Extract amqp connection into its own class. Create avro and mongo objects in factory.

Mike Gerwitz 64718d5513 RatingService: Fix initialRatedDate and lastRatedDate reply
Recent changes caused the quote to be read before it was mutated by
_saveRatingData.

Mike Gerwitz f0e246deef RatingService#postProcessRaterData: Fix accidental indvRate change
I accidentally changed id=>after when prototyping data for the _new_
deferred rating (not yet written).  There were no tests for this code, which
was originally written in July of 2012 (see private lovullo.git repo), so it
was not caught until QA.

Mike Gerwitz 65e7880c81 RatingService: Improved error handling
This does only a slightly better job than before.
2019-10-29 13:36:55 -04:00
Mike Gerwitz 1ed8ad1cd7 RatingService: Return promise
This only replaces the callbacks at the highest level and starts to move
toward proper error handling.  The private methods do not yet properly
propagate errors.

Mike Gerwitz 1aa69c2a56 RatingService: Save rating data to separate field (ratedata)
This adds ratedata to the quote collection.  We use the existing saveQuote
method so that this operation is atomic.  We're also continuing to save to
the bucket for now so as not to break existing code, but the intent in the
future will be to remove all but necessary data that should be exposed to
the client.

Mike Gerwitz cffd9ddeb0 RatingServiceTest: Add type information for stubs
This also gets rid of the RatingServiceStub module, which is not used by
anything else.  I suspect that I originally added it to be shared by traits,
but that's no longer going to be the case (and the only remaining trait is
unfortunately untested atm, and will be going away).

Mike Gerwitz 767a248e44 RatingService: Convert to TypeScript
This was an adventure, and was also used as a peer programming exercise to
introduce TypeScript to other programmers in the office.

This class has far too many dependencies, which made this difficult.  The
approach was to create .d.ts files for dependencies and wait on moving those
over for now, otherwise the task will never get done.

The RatingServicePublic trait was left as such for the time being; I was
able to work around a bug that was making it difficult to mix it into a
prototype.

There were no logic changes; this was just type refactoring.

Mike Gerwitz e2edbfc7b2 src/numeric: New module
This beings to introduce compile-time safety for numeric values under the
assumption that they are enforced by the runtime.  See docblock for more
information.

Mike Gerwitz 44ad6437e2 {src,test}/.npmignore: New files
NPM was not publishing the compiled JS files (from the TS input) because
they were present in generated .gitignore files.  .npmignore takes
precedence.

Mike Gerwitz 16409a014f TokenedDataApi: Accept or kill token
Rather than leaving a token in a DONE state, we should either transition to
ACCEPTED or DEAD depending on whether the token was superceded.

* src/server/dapi/TokenedDataApi.ts (_replyUnlessStale): Accept token when
  not superceded, otherwise kill.
  [store]: New param.
  (request): Use it.
* test/server/dapi/TokenedDataApiTest.ts: Update accordingly.
2019-10-18 09:55:11 -04:00
Mike Gerwitz e003abcd4b Integrate TokenedDataApi into system
This changes the easejs interface for DataApi, which requires adding the
param to everything.  The TS interface was created in a previous commit and
already contained this parameter.  The idea is to remove the easejs
interface in the future, but traits are a barrier to that atm.

DocumentServer and controller demonstrate the mess that we have with regards
to instantiating dependencies.  This needs to change---DocumentServer itself
was something that was started but never fully realized.  It makes this
incredibly confusing, difficult to follow, and complicates important error
handling that ought to be taking place.  It also discourages implementing
additional dependencies.

I'm not going to go through and provide a ChangeLog-style commit message for
this commit.  I'm too exhausted by this crap.

Mike Gerwitz d8c065817f NodeCallback<T, R>: New type to simplify callback declarations
Just trying to reduce some boilerplate.  I kept this as a separate commit to
illustrate clearly how this type of things is done since we'll have people
learning TypeScript.

* src/types/misc.ts (NodeCallback<T,R>): New type.
* src/server/dapi/TokenedDataApi.ts: Use it.
* test/server/dapi/TokenedDataApiTest.ts: Use it.

Mike Gerwitz 07c8b55475 TokenedDataApi: New class
This integrates the PersistentTokenStore into the DataAPI system via a
decorator.  Unfortunately, it requires an API change and propagating data
through the system is a huge mess, which is the topic of a following
commit.  The API modification was a compromise.

This modifies the interface of DataApi to include a third parameter.  I am
continuing to export the old easejs interface for an incremental migration
away from it.  That old interface will be modified next commit, since
it requires modifying a lot of files and will muddy up this commit.

* src/dapi/DataApi.ts: Rename from js.  Add types.  Add new interface.
  Continue exporting old.
* src/server/dapi/TokenedDataApi.ts: New class.
* test/server/dapi/TokenedDataApiTest.ts: New test cases.
2019-10-18 09:55:11 -04:00
Mike Gerwitz b3ab082e9c {=>Persistent}TokenStore
This creates an interface for TokenStore.  The main motivation of this right
now is testing, since I'm punting on figuring out a mock framework right
now (due to time constraints).

* src/server/token/TokenStore.ts: Rename file.
* src/server/token/store/PersistentTokenStore.ts: Rename from TokenStore.
* test/server/token/TokenStoreTest.ts: Rename file.
* test/server/token/store/PersistentTokenStoreTest.ts: Rename from TokenStoreTest.

Mike Gerwitz c8589a1c57 TokenDao, TokenStore: Track most recently created tokens
This is much more useful information than the last modified.  For example:

- Token A is created.  It becomes the last modified.
- Token B is created.  It becomes the last modified.
- Token A completes.  Mismatch.  It becomes the last modified.
- Token B completes.  Mismatch.  It becomes the last modified.

So in this case, we're unable to use the flag to determine whether we should
ignore the token.  But if we instead us the new flag to see what token was
last _created_, the problem is solved.

This should have been obvious the first time around.

* src/server/token/MongoTokenDao.ts (updateToken): Query
    `lastState'.  Return its value.  Update its value.
  (getToken): Query lastState.  Return its value.
* src/server/token/Token.ts (Token)[last_state]: New field.
* src/server/token/TokenDao.ts (TokenQueryResult, TokenNamespaceResults):
    Use type instead of interface.
  (TokenStateHistory): New type.
  (TokenNamespaceData)[lastState]: New optional field.
  (TokenData)[prev_state]: New field.
* src/server/token/TokenStore.ts: Return previous state data for each
    method.
* test/server/token/MongoTokenDaoTest.ts: Add last_state.
* test/server/token/TokenStoreTest.ts: Likewise.

Mike Gerwitz 0a9a5fe56e TokenStore: Provide document id via constructor
The primary use case for this is currently the DataAPI, and the quote id is
only available at the highest level of the server, before dapis are
processed.

In any case, the TokenStore was already described in terms of a combination
of document id; namespace; and root field; so it makes sense for doc id to
be part of the constructor.

If a more generic TokenStore is needed in the future, we could go back to
the previous API and wrap it in another class, like a partially applied
function (e.g. `DocumentTokenStore`).

* src/server/token/TokenStore.ts: Move doc_id out of arguments and into the
  constructor.
* test/server/token/TokenStoreTest.ts: Update accordingly.
2019-10-18 09:55:10 -04:00
Mike Gerwitz 929acf0e90 TokenStore: Implement for token lookups and creation
Does not yet support token updates.

* src/server/token/Token.ts (TokenStateDeadable, TokenStateDoneable,
  TokenStateAcceptable, Token): New types.
* src/server/token/TokenStore.ts: New class.
* test/server/token/TokenStoreTest.ts: New test case.
2019-10-18 09:55:10 -04:00
Mike Gerwitz 9997da3f65 TokenDao: Return previous state
This causes the DAO to return the state of the document prior to the
database operation (in the case of a retrieval, the previous state is the
same as the current state).  This will allow determining whether other
tokens were modified since a previous request.

* src/server/token/MongoTokenDao.ts: Stop using TokenType in favor of new
    TokenState.
  (updateToken): Query for and return previous state.  Use findAndModify
    instead of update.
  (getToken): Return previous state.  Minor changes to account for new
    TokenQueryResult types (null=>undefined).
* src/server/token/Token.ts: Add comments for existing Token{Id,Namespace}
    nominal types.
  (TokenState): New string enum.
* src/server/token/TokenDao.ts: Import new TokenState.
  (TokenDao)[updateToken]: Use it.
  (TokenType): Remove.
  (TokenQueryResult, TokenNamespaceResults, TokenNamespaceData):
    null=>undefined for unavailable value.  null was wrong.
  (TokenStatus): Token{Type=>State}.
  (TokenData)[prev_state, prev_status]: New fields.
* test/server/token/MongoTokenDaoTest.ts: Update tests accordingly.
2019-10-18 09:55:10 -04:00
Mike Gerwitz 5b279f77cb TokenDao (#updateToken): Return updated data
Since some of these data are generated within TokenDao (e.g. the timestamp),
the caller cannot infer all values.

* src/server/token/MongoTokenDao.ts (updateToken): Return
  Promise<{void=>TokenData}>.
* src/server/token/TokenDao.ts (TokenDao)[#updateToken]: Update interface
  accordingly.
* test/server/token/MongoTokenDaoTest.ts: Update test accordingly.
