Teon Banek 4601f6c368 Add filtering BFS by edge type Summary: Antlr grammar has been updated to support putting edge types after the BFS symbol. Planner collects edge type filters for BFS and inlines them in the operator by joining the filter with the user input BFS filter itself. This requires no change from the standpoint of the operator. On the other hand, in order to use the faster lookup by a single edge type, `ExpandBreadthFirst` operator now accept an optional edge type. The edge type is passed from the planner only if the user is filtering by a single type. Unit tests as well as tck have been updated.

Memgraph quality assurance

In order to test dressipi's queries agains memgraph the following commands have to be executed: 1. ./init [Dxyz] # downloads query implementations + memgraph # (the auth is manually for now) + optionally user can # define arcanist diff which will be applied on the # memgraph source code 2. ./run # compiles and runs database instance, also runs the # test queries

TODO: automate further

TCK Engine

Python script used to run tck tests against memgraph. To run script execute:

1. python3 tck_engine/test_executor.py

Script uses Behave to run Cucumber tests.

The following tck tests have been changed:

1. Tests where example injection did not work. Behave stores the first row
   in Cucumber tables as headings and the example injection is not working in
   headings. To correct this behavior, one row was added to tables where
   injection was used.

2. Tests where the results were not always in the same order. Query does not
   specify the result order, but tests specified it. It led to the test failure.
   To correct tests, tag "the result should be" was changed with a
   tag "the result should be (ignoring element order for lists)".

3. Behave can't escape character '|' and it throws parse error. Query was then
   changed and result was returned with different name.

Comparability.feature tests are failing because integers are compared to strings what is not allowed in openCypher.

TCK Engine problems:

1. Comparing tables with ordering.
     ORDER BY x DESC
     | x | y |    | x | y |
     | 3 | 2 |    | 3 | 1 |
     | 3 | 1 |    | 3 | 2 |
     | 1 | 4 |    | 1 | 4 |

2. Properties side effects
     | +properties | 1 |
     | -properties | 1 |

     Database is returning properties_set, not properties_created and properties_deleted.
