Hi @VinodAnandan - I looked into the tests and fixed the main problems that are related to the migration to cyclonedx 1..6.

Hi @nscuro, I pushed some code to bump the test coverage of the PR above the required threshold. The corresponding pipeline actions have been hanging since yesterday morning (https://github.com/DependencyTrack/hyades-apiserver/actions/runs/11177278805) with a message "This workflow is awaiting approval from a maintainer in #933". Could you check what's going on? |

@san-zrl PRs from first-time contributors need explicit approval for workflows to run. Approved it now. |

@VinodAnandan, thanks for letting me know. Diff test coverage is not quite on target Do you want me to further increase this number? |

@san-zrl Don't sweat about the coverage too much for now. I haven't yet had the chance to thoroughly review the PR, and I am taking a few days "off" at the moment so there's limited time I'm spending on GitHub. Assigning this to me, I'll get back to you ASAP. |

The character limits on BOM_REF, LOCATION and ADDITIONAL_CONTEXT seem a bit optimistic to me. If LOCATION ends up being a file path, I can see the limit of 255 being broken rather trivially. Similar story for ADDITIONAL_CONTEXT, which seems to be a field of arbitrary content?

Hi @nscuro, thanks a lot for your review.
The code above comes from the definition of the OCCURRENCES table. The PR currently adds all crypto-related data fields that our scanner (https://github.com/IBM/cbomkit) generates. We can drop OCCURRENCES because the location of crypto assets in source is probably not important in DT.
Nevertheless, the your point re. the size of the varchar columns is still valid. There is no proper reasoning behind the current numbers. We started with some guesstimates based on standard (https://cyclonedx.org/docs/1.6/json/) and examples (https://github.com/CycloneDX/bom-examples/tree/master/CBOM) and simply doubled if the initial numbers weren't sufficient. I'd gladly use other numbers with better foundation. If data size is an issue we should go through all varchars one-by-one and decide (a) does it have to be persisted and (b) if so, what size is needed.

Occurrence will likely come to DT in the future to cater to other use cases, but if it's not crucial for the crypto functionality it's good to drop here IMO.

In PostgreSQL it's all TEXT (unlimited length) behind the scenes, with an implicit CHECK constraint for the length. So other than preventing users from storing GBs of useless data, size constraints don't matter. With this in mind, I think choosing an initial length of 1024 should be fine.

Okay, thanks.
- I will remove Occurrence with the next commit.
- VARCHAR length will default to 1024 unless we know better.

Wouldn't it make more sense to have a COMPONENT_ID column on the CRYPTO_PROPERTIES table?
Given the FK constraint with onDelete="CASCADE", the current setup would cause the COMPONENT record to automatically be deleted when CRYPTO_PROPERTIES gets deleted. It should be the other way around, i.e. CRYPTO_PROPERTIES being deleted automatically when COMPONENT gets deleted.
There was a problem hiding this comment.
Yes, true. This would be a better idea but I didn't manage to make this work.
I tried to specify a COMPONENT_ID in CRYPTO_PROPERTIES that refers upwards to the enclosing component along with an FK constraint that would cause the right order of cascading deletes. This led to a problem when trying to persist the modified crypto asset properties object. I reproduced the error msg with stacktrace and appended it below for reference. It turns out that CryptoAssetProperties@5af49362 is not the instance from ModelConverter (in which the component id was properly set) but another instance created somewhere deep down in the transaction code.

Just to be sure, is this how you modeled the relationship in this case? https://www.datanucleus.org/products/accessplatform_6_0/jdo/mapping.html#one_many_fk_bi

I wanted the 'inner' dependent object to be fetched when the 'outer' object is queried and I wanted the cascading delete to work in both ways. The code does that, so I think we can leave it as is.
The fetching works since the inner objects (e.g., CryptoAssetProperties) are modelled as persistent members of the outer (e.g., Component) object. Inner objects cannot exist without their 'outer' container. Thus, cascading delete must work in both ways:
- Deleting an 'outer' object must delete all 'inner' objects. This is guaranteed by the
dependent = "true"flag in thePersistentannotation. Here is an example:hyades-apiserver/src/main/java/org/dependencytrack/model/Component.java
Lines 394 to 397 in 279450c
- Deleting an 'inner' object renders the outer objects invalid and they must be deleted. This is guaranteed by the foreign key constraints. Here is an example:

Lines 269 to 272 in 279450c

Can we add a few tests with crypto BOMs here that verify correct ingestion of data?
From what I'm seeing we're currently relying on the ORM to implicitly persist the object graph, but it may very well be that a more manual approach is necessary (see BomUploadProcessingTask#processComponents).

I will add some tests. Your observation is right, we rely on the ORM magic.

From what I understand from the schema, these are BOM refs. I'm wondering if they should be resolved prior to persisting them, such that these would be foreign keys instead? Is there a reason to leave them plain like this?
There was a problem hiding this comment.
You're right, they should be resolved. I haven't done this yet because the issue appears in many places where the standard has xxxRef data fields. In most cases, these are bomrefs that could be resolved to components. Most prominently, the bomref resolution question arises in the dependencies. Here DT currently stores a JSON structure which imho cannot not be the final solution. Hence I thought that bomref resolution ist still an open issue and left the refs plain for the time being.

Very much agreed. An overhaul is planned but needs more fleshing out: DependencyTrack/dependency-track#3452
Would the resolved references here be part of the dependency graph though, or would it be a separate, graph-like structure? Seeing as the CDX standard still lacks "type" properties on dependency graph nodes...
There was a problem hiding this comment.
In principle it's the same tree structure. The bomrefs in the ref fields must obviously point to other components in the BOM otherwise they would be dangling. In a sense, the standard is "over-specified": You can have ref fields that point to components and you can have dependency objects that also state that one component depends on another. It is not clear if the specification of a signatureAlgorithmRef requires the specification of a dependency object.
I think our final goal should be to model signatureAlgorithmRef as
private Component subjectPublicKeyRef;that is set as the result of the bomref resolution. Maybe we can make these fields transient because the get re-created on the fly when the BOM is loaded.

Could this just be an array column in the ALGORITHM_PROPERTY table?

Yes, absolutely. I avoided array column types since they are not supported by all db systems. But if we stick to postgres using array types would greatly simplify the table structure. There are a couple of similar structures in CBOM 1.6 where we could migrate to arrays.

I'd replace this join table with a join column (i.e. have a COMPONENT_ID column in the OCCURRENCES table). Since the component<->occurrence relationship is 1:N, the overhead of a join table is not necessary.

General question: Is all this new data required to make crypto integration useful? One thing I'd like to avoid is persisting a lot of data without having a need for it.
The less data we store, the fewer pains we'll have in the future as the CycloneDX specification evolves and shifts things around. Due to the tight coupling of the model to the CycloneDX spec, that is definitely something to be vary about.
There was a problem hiding this comment.
As I said, we could drop Occurrences. Given that each crypto component can have many occurrences this would already save a lot. Other than Occurrences, the PR adds the entire cryptoProperties realm from https://cyclonedx.org/docs/1.6/json/ to persistence. There are some things that may be of less importance in the context of DT (e.g., the implementation platform and execution env in algorithm properties). These are only enum values and the saving potential is limited. We could have a telco and go through the data fields one by one. Perhaps there's too much detail in the standard for DT's purposes.

What data are we trying to capture with this increase in fetch depth? I wonder if FetchGroups would be a better tool to avoid over-fetching of data that is not strictly needed.
There was a problem hiding this comment.
The frontend PR contains code for rendering crypto properties. They form an additional layer in the persistence model which must be fetched for rendering (fetch depth 2 was not enough). To keep things simple I just raised the fetch depth to make this work. We could define a dedicated crypto component fetch group and use this only when crypto assets are queried.
There was a problem hiding this comment.
OK, I'd propose we deal with this once everything else in place, as it's just an optimization and DataNucleus' fetch behavior can be quite fiddly to tune.
