This adds deprecations in preparation for `pg@7.0`
- deprecate using event emitters on automatically created results from client.query.
- deprecate query.promise() - it should never have been a public method and it's not documented. I need to do better about using _ prefix on private methods in the future.
- deprecate singleton pool on the `pg` object. `pg.connect`, `pg.end`, and `pg.cancel`.
* Remove redundant tests
* Add client connectionString test
Add test to ensure { connectionString } is respected as an argument to the client constructor
* Add test for connection string property
Also fixed some legacy require statements.
* Going red: using a config object creates two pools when missing some params
It should only create a pool in a consistent way, even if some params
are not provided in the first place.
* Delay the pool name generation to make it consistent between calls
* Don't fallback to empty object as config is already defined
* Fix escaping of libpq connection string properties
Fix handlings of libpq connection properties to properly escape single
quotes and backslashes. Previously the values were surrounded in single
quotes which handled whitespace within the property value, but internal
single quotes and backslashes would cause invalid connection strings to
be generated.
* Update expected output in test to be quoted
Update the expect host output in the connection parameter test
to expect it to be surrounded by single quotes.
* Add test for configs with quotes and backslashes
They were disabled by 4cdd7a116b without comment; it seems that this might have been unintentional?
In any case, they should probably be enabled, updated, or removed.
A long standing bug was the pure JS client didn't accept or call a callback on `client.end`. This is inconsistent with both the documentation & general node patterns.
This fixes the issue & adds a test. The issue did not exist in the native version of the client.
The promise adapter I had implemented wasn't spec compliant: it didn't accept both `onSuccess` and `onFailure` in the call to `query#then`. This subtly broke yield & async/await because they both rely on `onError` being passed into `Promise#then`. The pool was also not returning the promise after a client was acquired, which broke awaiting on `pool.connect` - this is also fixed now.
* Initial work on removing internal pool
* Port backwards-compabible properties
* Cleanup test execution & makefile cruft
* Attempt to fix flakey error test
* Make Query & NativeQuery implement the promise interface
* Fix test
* Use older node API for checking listener length
* Do not test for promises on node@v0.10.0
There was some nasty global-ish variable reference updating happening when the native module 'initializes' after its require with `require('pg').native`
This fixes the issue by making sure both `require('pg')` and `require('pg').native` each initialize their own context in isolation and no weird global-ish references are used & subsequently stomped on.
When a __prepared statement__ has no body in the query the backend responds with an `emptyQuery` message but never with a `commandComplete` or `errorResponse` message. The client was hanging forever waiting for one of the other two expected messages. The server was hanging forever waiting for the client to respond with a `sync` message. This change has the client send the required `sync` on receipt of an `emptyQuery` message when the query is a prepared statement. Fixes#822
