When performing a db-diff using the latest datomic release I discovered that the db-diff
function doesn't complete as expected due to an exception.
CompilerException java.lang.IllegalArgumentException: :db.error/not-a-keyword Cannot interpret as a keyword: Documentation string for an entity., no leading :, compiling:(/home/bjc/Workspace/wonderdrug/maestro/src/clj/maestro/datomic/migrations.clj:14:13)
This looks to be because the pull rule used by get-attributes
defines a :db/doc [:db/ident]
.
This used to simply be ignored but as per more recent releases (see https://groups.google.com/forum/#!topic/datomic/F9-9KkKTSiE) this behavior has changed and causes an exception.
Changing the pull shape found at https://github.com/kibu-australia/rawat/blob/master/src/rawat/core.cljc#L213 to:
[:db/ident :db/unique :db/index :db/fulltext :db/isComponent :db/noHistory {:db/valueType [:db/ident] :db/cardinality [:db/ident]} :db/doc]
looks to resolve the problem (although I fear perhaps cause regressions in older datomic instances).
