3f424c0121 feat: add an API to time out query executions 
Currently, if a predicate is hard to match on the Rust side, a sizable
query against a very large file can take forever, and ends up hanging.
This commit adds an API function `ts_query_cursor_set_timeout_micros` to
limit how long query execution is allowed to take, thereby negating the
chance of a hang to occur.

Merge pull request #1589 from alex-pinkus/deduplicate-core-ids 
Ignore duplicate states when initializing subgraphs in `ts_query__analyze_patterns`
 2022-01-17 13:54:31 -08:00
Alex Pinkus
eaf9b170f1 Don't start with duplicate states in ts_query__analyze_patterns 
This change exposes a new `primary_state_ids` field on the `TSLanguage`
struct, and populates it by tracking the first encountered state with a
given `core_id`. (For posterity: the initial change just exposed
`core_id` and deduplicated within `ts_analyze_query`).

With this `primary_state_ids` field in place, the
`ts_query__analyze_patterns` function only needs to populate its
subgraphs with starting states that are _primary_, since non-primary
states behave identically to primary ones. This leads to large savings
across the board, since most states are not primary.

9bac066330 Deal with quantifiers appearing on capture's enclosing patterns 
- Use a proper enum type for quantifiers.
- Drop quantifiers from `TSQueryStep`, which was not used.
- Keep track of the captures introduced during a pattern parse, and
  apply the quantifier for the pattern to the captures that were
  introduced by the pattern or any sub patterns.
- Use 'quantifier' instead of 'suffix'.
