Hello, during the adaptation of the openBIS for our lab I have encountered multiple bugs and unexpected behavior in the clients, mainly in pybis.
Javascript:
src/v3/util/Json.js:116
you are converting jsonId natively to boolean in the condition, which causes id=0 to be evaluated as false and not mapped. This is not a problem for the response from the server, as it sends ids from 1, but the client encodes ids from 0, so it is not possible to encode then decode the object on client only. Which admittedly sounds like a weird use-case, but it is useful for serialization of the objects for SSR or similar.
Another thing is that dependency on the jquery and other browser-only libraries makes the client basically unusable anywhere else, such as node.js, so React and other frameworks. I know it can be imported dynamically, but then the SSR and Server Components are unusable as the data cannot be fetched on the server. I personally repackaged the client in a way where it is not necessary and it is usable server-side, but I think it would be generally useful not to have it browser depended.
Pybis:
definitions.py:86
there is comma after showParentMetadata which makes it impossible to get them.
openbis_object.py:207
It happened to me that the deletion_id was None, and then it crashed on this line
property_reformatter.py:69 and 71
Adding string to an array with += causes the string to break into characters in the list. Instead I would add new items with .append() function
pybis.py:5681
Searching sample type codes with StringStartsWithValue causes to return unexpected results, especially with sample codes that share the same prefix. For example if user inputs “DEVICE_PART” they expect to get type groups for type “DEVICE_PART” and not also “DEVICE_PART_INSTANCE”, etc. The same for the type groups. Instead, I would expect to be able to search with wildcard pattern if I want the sample to start with a prefix like so “DEVICE_PART*”, but that is only a personal preference.
utils.py:237
I would expect this string to have the ‘r’ prefix so the backslashes are not interpreted. re.match(r"...", ident).
And in general I noticed that pybis struggles with the decycled objects from backend. If the object is referenced only by Id within the response, because it has been defined earlier in the response, it returns only the id as string and not the object itself, which creates weird situations where the same code works and does not, depending on the state of the database and connections within it. I noticed this with the typegroups search, when multiple types are returned and some of them belong to the same group, the group definition itself is readable only on the first object, and then the following ones just use @id=x instead as the attribute, so suddenly instead of the type definition one gets a string.
But in general I really love the changes you made to the 7.0. The multivalue/array types, type groups and the AFS is great. It allowed me to do what would have been very difficult without them. Good job, keep up
