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)
- added filter and stats icons to log stream labels
- removed click handler from label itself
- click on stats icon calculates label value distribution across loaded logs lines
- show stats in hover
- stats have indicator which value is the current one
- showing top 5 values for the given label
- if selected value is not among top 5, it is added
- summing up remaining label value distribution as Other
- Logging datasource sends error string directly in the message body
- allowing response body to be an error when query transaction failed
- added throw in case we ever encounter unhandled errors again (forces us to fix the issue)
- 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
- moved from grid to flexbox
- calculate Explore results only when query transactions change to prevent expensive re-renders
- split up rendering of graph and log data
- render log results in 2 stages
- 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
