From a7708a325f89692bccb662af46b5b03ac732a463 Mon Sep 17 00:00:00 2001 From: Marcela Poffald Date: Thu, 5 Oct 2023 17:45:17 -0500 Subject: [PATCH 01/13] Filter and format malli error messages We attempt to choose the most useful errors by doing as follows: - if there is a top-level failures from one of our `:fn` schemas, we just use that one - Otherwise, we search through the errors: - we prefer messages with the longest `:in` values, which means the failure was in more sense more "specific" - if there's only one of those, we take it - otherwise, we take a chunk of errors which share the same `:in`, meaning the same portion of the value failed multiple branches of the schema. We arbitrarily choose the first - we see if those all share some common disjunction farther up the tree. Error messages on `:or`/`:orn`s can be written to express the requirements in one sentence, which we prefer over using the children of that disjunction - if not, we just pick one from the chunk Other changes: - use version of `-resolve-root-error` with two fixes: - ensures `:error/fn`s have access to a correct value. This fixes a bug which was causing `nil` values in error messages - guard against `:invalid-schema` error when root error is due to an extra key not present in the schema - add override that attempts to improve upon invalid-type errors --- src/fluree/db/api/query.cljc | 6 +- src/fluree/db/query/fql/syntax.cljc | 99 +++++------ src/fluree/db/query/history.cljc | 81 ++++++--- src/fluree/db/validation.cljc | 156 ++++++++++++++++-- test/fluree/db/query/fql_parse_test.clj | 211 ------------------------ test/fluree/db/query/history_test.clj | 2 +- 6 files changed, 256 insertions(+), 299 deletions(-) delete mode 100644 test/fluree/db/query/fql_parse_test.clj diff --git a/src/fluree/db/api/query.cljc b/src/fluree/db/api/query.cljc index 18619ce8e..6acc10e09 100644 --- a/src/fluree/db/api/query.cljc +++ b/src/fluree/db/api/query.cljc @@ -93,10 +93,10 @@ (catch* e (throw (ex-info - (str "History query not properly formatted.
