* Generate field names with brackets when needed.
* Stop hard-wiring complex selectors as `["field1", "field2[sub-field3]"]`
and instead represent them as a more consistent `["field1", "field2", "sub-field3"]`
* Convert all filter strings ending with square brackets to an array.
Stop special-casing 'metadata.labels[X]' and handle any query string that ends with '[...]'.
* Stop checking for pre-bracketed terms in constant field-accessor arrays.
In this commit we stop converting string arrays like
`["metadata", "labels[k8s.io/deepcode]"]` into the database field
`"metadata.labels[k8s.io/deepcode]"` and instead will do a
naive `join` to give `metadata[labels[k8s.io/deepcode]]`. The solution
is to never express the above terms in separate fields, like
`["metadata", "labels", "k8s.io/deepcode"]`. This also better reflects
the stucture of the referenced object.
* gofmt changes
* Simplify comment about 'smartJoin'.
* Add more fields to index when sql-caching is on.
* Restore the gvkKey helper, add event fields.
The UI team wasn't sure whether the event fields should go in the empty-string group or in 'events.k8s.io',
so let's go with both until/unless specified otherwise.
* More fixes to the fields to index:
- Remove the erroneously added management.cattle.io.nodes fields
- Use the builtin Event class, not events.k8s.io (by looking at the dashboard client code)
* Start on the virtual-field work.
* Map `Event.type` to `Event._type` for indexing.
* Add a unit test for field replacement for Event.type
* Add label processing.
* Don't test for transformation of event objects in the common module.
* Parse metadata.label queries differently.
* Improve a variable name that turned out to not be temporary.
* No need to specifically cache certain labels, as all are now cached.
* Add a test to verify simple label (m.labels.foo=blah) queries work.
* 'addLabelFields' never returns an error.
* Delete superseded function.
* Was calling 'addLabelFields' one time too many.
* Start using k8s ParseToRequirements
* Pull in the k8s parser.
* Successfully test for quotation marks.
* Add quoted strings to the lexer.
* Move to a forked k8s label lexer to include non-label tests.
* Improve and test the way quoted strings in the query are detected.
* Reinstate the original Apache license in the derived code.
Following clause 4.3 of the Apache license:
"You must cause any modified files to carry prominent notices stating that You changed the files..."
* Ignore case for operators.
* Test IN multiple-target-values
* Test the not-in operator.
* Ignore case for operators.
SQL is case-insensitive on field names and values, so this just adds consistency.
* Added tests for parsing EXISTS and NOT-EXISTS queries.
* Parse less-than and greater-than ops
* Lasso's `CacheFor` now takes a `watchable` argument.
* Support 'gt' and 'lt' as synonyms for '<' and '>'.
I see both types of operators being bandied about -- it's easy to support the aliases.
* typo fix
* Have the filter parser allow exist tests only on labels.
Also reduce the case where there's no namespace function.
* Specify hard-wired fields to index alphabetically.
* Remove unused variable.
* Parser: 'metadata.labels[FIELD]' is valid
* Pull in new gvk fields from main (and keep in alpha order).
* Fixed a couple of drops done during the last rebase.
* Add a reminder to keep the entries in alpha order.
* Test TransformLabels
* Remove TransformLabels
* Remove unused/unneeded code.
* Describe diffs between our label-selector parser and upstream's.
* Use the merged lasso 46333 work.
* Drop unused field.
* Tighten up the code.
* Specify which commit the label selector parser is based on.
* Allow both single-quoted and double-quoted value matching, doc difference.
* More review-driven changes:
- Stricter processing of m.l.name keys:
Require ending close-bracket for a start-bracket
- Comment fix
- Moving sql processing from lasso to steve: some changes missed in rebase
* Drop support for double-quotes for string values.
For now on only single-quotes (or none where possible) are allowed.
* Renaming and dropping an init block.
* Quoted strings are dropped from the filter queries
In particular, label values have a specific syntax: they must
start and end with a letter, and their innards may contain
only alnums '.', '-' and '_'. So there's no need for quoting.
And that means now that `=` and `==` do exact matches,
and the `~` operator does a partial match.
`!=` and `!~` negate -- note that `!~` is a stricter operation than `!=`,
in that given a set of possible string values, `!=` will accept more
of them than `!~`. Maybe I shouldn't have gone here, but these operators
reminded me of learning about `nicht durfen` and `nicht sollen` in German,
or something like that.
* Move a constant definition to the module level.
* Remove commented-out code.
* Remove unused func and adjacent redundant comment.
* Replace primary/secondary sort fields with an array of sort directives.
* Allow more than 2 sort-params in a search query.
* Add a virtual 'status.ready' field to clusters.
* Rename status.ready -> status.connected
* Set virtual field 'spec.internal' <- spec.displayName == 'local'
* Need to declare all virtual fields to index.
* Ready clusters have condition[type==Ready && status=True]
* Update the README to reflect generalized sorting.
* Bump lasso to get revised sort directives.
* Review-driven changes, mostly comments and drop unneeded code.
* Add unit tests to verify sort-order stringification.
* Ignore empty-string sort components.
* Fix a rebase mishap.
* Drop unneeded commented-out code.
* Clusters have a 'spec.internal' field, no need to synthesize one.
* Added a note on square-brackets for label references.
This should be added to the README for filter queries in the PR for 46333.
* Bump to latest sqlcache-free lasso
* Refactor ID based partitioning, add unit tests
This resolves an issue where the requested namespace filter was not
always honored.
* Correct naming issues to appease the linter
Adds logic which adds virtual fields resources. This allows these fields
to be sorted/filtered on when the SQL cache is enabled. Id and
metadata.state.name were added as the first two fields.
This uses SQLite-backed informers provided by Lasso with https://github.com/rancher/lasso/pull/65 to implement Steve API (/v1/) functionality.
This new functionality is available behind a feature flag to be specified at Steve startup
