A logging query has a selector part and a regexp. The regexp matches are highlighted when results return.
This change adds live preview to matches when modifying the regexp in a search field.
- delegate retrieval of match query to datasource
- datasource returns search expressions to be used to highlight a live preview of matches
- logs row now takes preview highlights
- logs row renders preview highlights with dotted line to distinguish from query run matches (solid line)
- fix react-highlight-words version to ensure custom chunk matcher
- custom chunk matcher can now also take incomplete regexps, eg, `(level` without inifinte looping
- perf: debounce of live preview to 500ms
- perf: only top 100 rows get the live preview
- preview is only supported with one query row (multiple rows semantic makes this tricky: regexp for row n should only filter results for query n)
- ensure that selectors have to be preceded by whitespace or line beginning
- glacing over the fact that ` {0,1}` could be a valid regexp, but we're using space as query/regexp separators anyway, so I think it's fine for now
- fork promql's tokenizer (need to specify that labels context can only follow beginning of line or whitespace)
- remove unneeded syntax features
- only present history items when field is empty
- fixed typo
- moved result calculation to explore utils
- use component keys instead of componentWillReceiveProps
- require logs to have and id, to as use as Logs component key
- render delay based on row count
- adds a custom label renderer to Logs viewer in Explore
- labels are no longer treated as strings, they are passed as parsed objects to the log row
- label renderer supports onClick handler for an action
- renamed Explore's `onClickTableCell` to `onClickLabel` and wired up log label renderers
- reuse Prometheus `addLabelToSelector` to modify Logging queries via click on label
- added tests to `addLabelToSelector`, changed to include the surrounding `{}`
- use label render also for common labels in the controls panel
- logging meta data section has now a custom renderer that can render numbers, strings, and labels
- style adjustments
- since the DataQuery rewrite, Explore starts by submitting its queries (Explore cant know if the queries are emtpty)
- The datasource intercepts an empty query and returns an empty list of time series, and also no table for the table query.
- The query hinter then received no series to analyse and was not guarding against this.
- This PR adds this guard.
- add `onToggleSeries` to Explore Graph props
- toggling a Logging Graph series from the legend propagates its hidden series to Logs
- Logs translates hidden series alias to LogLevels
- Logs filters out hidden log levels
