I have run into an interesting issue here.

Basically, I am creating a new object, and then making changes in that object twice, committing it each time. In total, javers.commit is called three times.

However, when I use a javers shadow query, I only get two shadows: The one with the initial commit, and the one with the latest commit. The shadow with the first change is missing.

  • [shadows[1]] Initial Commit
  • [MISSING] First Change
  • [shadows[0]] Second Change

Interestingly, however, the shadow IDs in the commitMetadata acknowledge that there is a version they're missing:

  • entryShadowList[0].commitMetadata.id = 3.0
  • entryShadowList[1].commitMetadata.id = 1.0

...so, whatever happened to Version 2.0, and why is it not returned?

Any idea what could cause this? I have already tried to add withScopeDeepPlus(999) to the JqlQuery that gets the shadows, like this:

	public static <T> List<Shadow<T>> shadowsQuery(
		Javers javers,
		String entryId,
		Class<T> entryClass
	) {
		JqlQuery entryQuery = QueryBuilder.byInstanceId(entryId, entryClass)
			.withScopeDeepPlus(999)
			.build();
		List<Shadow<T>> entryShadowList = javers.findShadows(entryQuery);
		LOGGER.info("Found the following shadows for: " + entryId);
		for(Shadow<T> entryShadow : entryShadowList) {
			T message = entryShadow.get();
			LOGGER.info(message);
		}
		LOGGER.info(entryShadowList.size() + " Shadows total");
		return entryShadowList;
	}

...however, it still only gets the two shadows listed above. The middle version is still missing.

For Reference, here's an excerpt of the data structure that I'm using, and where I make the changes:

ReqIf //<- The Entity
├TheHeader
├CoreContent
│└ReqIF_Content
│ ├Datatypes
│ ├SpecObjects
│ │└List<SpecObject> //<- One or more of these get removed in each request, should be 27 in initial commit, 26 after first change, and 18 after the second change
│ ├SpecRelations
│ ├SpecTypes
│ ├Specifications
│ └SpecRelationGroups
└ToolExtensions

Update: I tried working around this by adding a custom field public int majorVersion to the top level entity and manually incrementing it with every commit, but somehow that only made everything worse. Now the shadow query only returns the 3.0 version, and the 1.0 version is now missing along with the 2.0 version.

I am still trying to reproduce this with a simpler example. Meanwhile, if you have any ideas what could be behind such behaviour, please feel free to drop me any ideas.

I have just confirmed that the jv_snapshots collection in MongoDB where the Javers information gets stored contains snapshots with the versions 1 (the vast majority), 2 (a few) and 3 (only a handful), so from that I would also expect that three shadows should get returned. However, since that collection contains, like, 1989 objects, I can't just easily compare them.

Interestingly, when I do additional modifications, these spawn proper Versions that get retrieved correctly as shadows. It just seems to be the V2.0 that does not get correctly retrieved .

So, for example, when I make an initial commit and four changes, then this is what the Shadows query returns: (The version taken from shadow.commitMetadata.id):

  • V5.0 After fourth change
  • V4.0 After third change
  • V3.0 After second change
  • V1.0 Initial commit

That notably happens even though all the changes use the exact same logic.

I have followed that train further now, and have made the following very interesting obeservation.

The deletions I make come in two categories. While they are all deletions of a SpecObject, most of them just plainly delete that one SpecObject, but one of the deleted SpecObjects also has children, which then also get deleted in the same commit.

Now the interesting part here is that the Versions that are returned to me by the shadows query depend entirely on where the "Chain Deletion" happens.

If I put the Chain Deletion first, like this:

  • Initial Commit
  • Chain Deletion (id_exterior)
  • Single Deletion (id_steering_system)
  • Single Deletion (id_braking_system)
  • Single Deletion (id_lighting_systems)

...then the Shadows query returns me the following very valid response:

  • V5.0 with 16 SpecObjects
  • V4.0 with 17 SpecObjects
  • V3.0 with 18 SpecObjects
  • V2.0 with 19 SpecObjects
  • V1.0 with 27 SpecObjects

However, if I put the chain deletion last, like this:

  • Initial Commit
  • Single Deletion (id_steering_system)
  • Single Deletion (id_braking_system)
  • Single Deletion (id_lighting_systems)
  • Chain Deletion (id_exterior)

...then the Shadows query returns me the following. faulty response:

  • V5.0 with 16 SpecObjects
  • V1.0 with 27 SpecObjects

I can pretty much put the chain deletion wherever I like, and it will cause all previous versions to get "lost", which is really buggy behaviour, since the chain deletion should affect completely different objects than those affected by the single deletions.

For reference, here is a rough outline of the object tree:

              id_body
                  id_exterior
                      id_bonnet
                      id_doors
                          id_front_doors
                          id_rear_doors
                          id_trunk/boot
                      id_shell
                      id_sunroof
                  id_interior
                      id_clutch_unit
                      id_display_dashboard_unit
                      id_fuel_container
                      id_gear_box
                      id_luggage
                      id_occupants_passengers
                      id_power_unit
                      id_supporting_systems
                          id_AC_System
                          id_braking_system
                          id_electrical_system
                              id_electrical_generator_unit
                              id_electrical_harness
                              id_electrical_storage_unit
                          id_fuel_system
                          id_lighting_systems
                          id_steering_system

So, removing id_steering_system, id_braking_system and id_lighting_systems remove only one SpecObject each, but removing id_exterior also removes the seven child objects, which are not linked directly, but rather indirectly via a tree map.

Any ideas on how this could trigger this behaviour?

Still not having any luck creating a simplified reproduction that I can share.

However, here's the Changelogs as generated by changes.prettyPrint() for both cases:

Friction is the resistance to movement exerted by two objects on each other. Two forms of friction play a part in controlling a vehicle:       Kinetic or moving, and static or stationary. The amount of friction or resistance to movement depends upon the type of material in contact, the smoothness       of their rubbing surfaces and the pressure holding them together.

Traditional U.S. station wagons included a roll down window retracting into the tailgate to load small items or to allow the tailgate to be opened down on       its bottom mounted hinges. Because of the potential for carbon-monoxide fumes, the tailgate window on station wagons should be closed whenever the engine is running.      Two-way station wagon tailgates may be hinged at the side and the bottom so they can be opened sideways like a regular door, or drop downwards as load platform extenders.      They are designed with special handle(s) for opening in the selected direction on special hinges after the window is lowered.      A three-way design that was also used by Ford allows for the tailgate to be opened like a door with the window up.      General Motors developed a clam shell style 'disappearing' design where the rear window rolls up into the roof and the tailgate slides down and beneath the load floor.

This logs the change that removes the id_exterior and its children. Interestingly, however, that removal is not logged anywhere in that change, although it appears in the shadow for that version.

Meanwhile, if I get the Shadows for V1.0 and V2.0 and run javers.compare on them, then I get the following list of changes that contains the actual changes:

@bartoszwalacik : Any idea what could cause this? I was under the impression that the Changes should equal the Diff between two versions.

I have no analysed the changelogs above in detail, and it seems to me like they don't represent all the changes. For example, when reading all the value changes in the "working version" changelog and adding them up...

  • coreContent/ reqIF_content/ specObjects/ specObjects/ 13/ identifier.value changes from id_electrical_generator_unit to id_electrical_harness
  • coreContent/ reqIF_content/ specObjects/ specObjects/ 13/ longName.value changes from Gear_Box_Unit to Electrical_Harness
  • coreContent/ reqIF_content/ specObjects/ specObjects/ 13/ values/ attributeValues/ 0/ theValue.value changes from [Generator Description] to [Harness Description]

So, according to the changelog the identifier and description changes from Generator to Harness, but the name changes from Gear Box to Harness. But in reality (comparing the first and last Shadows), all aspects should have changed from Gear Box to Harness.

I have attached a spreadsheet in which I analysed this, in case it helps.

I have also tried "cheating" by adding an int revision fieldto the top-level entity and incrementing it by one every time I commit, but that only makes it behave more erratic.

For example, without the "revision" field:

  • Import -> V1.0
  • Remove Lighting -> MISSING
  • Remove Exterior -> V3.0
  • Remove Steering -> V4.0
  • Remove Braking -> V5.0

With the "revision" field:

  • Import -> MISSING
  • Remove Lighting -> MISSING
  • Remove Exterior -> MISSING
  • Remove Steering -> V4.0, revision = 4
  • Remove Braking -> V5.0, revision = 5

How can this happen? revision is a perfectly innocent int. How can it mess up things like this?

public class ReqIf extends XML_Tag {
	public List<ReqifNamespace> additionalNamespaces;
	public CoreContent coreContent;
	public TheHeader theHeader;
	public ToolExtensions toolExtensions;
	public int revision;
	@Id
	public String _id;
		reqIfData.revision++;
		updateCurrentVersion(reqIfData, workspaceID, databaseName);
		updateJaversVersion(reqIfData, workspaceID, databaseName, userName);

By the way, this also happens when I use a String for the revision.

Okay, I finally found out the reason behind all this eclectic behaviour, as well as the reason why I could not reproduce it with a simplified version.

The reason was simply the default limit for snapshots, as became apparent when I looked at the JqlQuery printout:

JqlQuery {
  IdFilter{ globalId: '...ReqIf/TL-211-Exterior-Interior.reqif' }
  QueryParams{ aggregate: 'true', limit: '100' }
  ShadowScopeDefinition{ shadowScope: 'SHALLOW' }
  Stats{  
    executed in millis: '3628'  
    DB queries: '1522'  
    all snapshots: '1768'  
    SHALLOW snapshots: '101'  
    CHILD_VALUE_OBJECT snapshots: '1667'  
  }
}

So it started working once I set up my query like this:

JqlQuery entryQuery = QueryBuilder.byInstanceId(entryId, entryClass).limit(9999).build();

With that knowledge, I believe I'll be able to create a test case for the erratic behavior that happens if the limit is set too low. I don't know what the intended behavior here is, but seeing as this cost me over two days to figure it out, I can't feel that this is intended behavior .

On a related note, is there a way to turn off the limit? I have it set to the Java maximum for int, aka 2147483647 for now, and assuming production-size updates generate only about 2000 new snapshots apiece (that is actually very realistic, since I've seen some of these ReqIF Files, and they are demonic beasts from the doom dimension), that would leave us with a hard limit of about 1 million versions per file, which is probably enough, but still...

@bartoszwalacik : I have now been able to replicate this in a simplified version as a test. If you tell me where and how to push it, I can give you access. I have already tried pushing to github in a new branch, but for some strange reason that did not work.

The basic test looks like this, but it also requires the data objects to go with it:

Well, sorry, I've been working on this issue for three days straight. I'll try to wrap it up. =>,<=

Not so much a bug, as more unexpected behavior and unclear documentation. I was aware of the limit functionality, but I would never have guessed that the limit would cause fewer versions to be loaded than expected, especially in a "V1, V4, V5" pattern. From what I read in the documentation, I figured that it would still load all the top-level objects, and then lose some of the child level objects or something. And I re-read the thing twice!

In fact, since that is apparently not what the limit does, is there another functionality that I can use to load only the top-level entities, so I can just get an overview of how many versions there are without loading the whole object tree to save time, and then use version-specific requests to get a certain version? The situation I have here is that I only have the top level entity, while all the other objects are effectively children of that entity.

Also, is there not an option for disabling the limit so I can always guarantee that all the versions are loaded? That would be kind of important.

Alternatively, to support pagination, it would really help to have a functionality to support either the latest, or the latest X version, such as I already mentioned on https://stackoverflow.com/questions/62467169/javers-quering-the-current-state-of-the-repository . I have also opened an issue for that here: #1002

Please tell me where the docs is misleading, I will fix it.

QueryBuilder.limit() limits Snapshots not Shadows.
A Shadow Query with SHALLOW scope doesn't load referenced entities

    /**
     * Limits number of Snapshots to be fetched from JaversRepository in a single query,
     * default is 100.
     * <br/><br/>
     *
     * Always choose reasonable limits to improve performance of your queries.
     */
    public QueryBuilder limit(int limit) {
        queryParamsBuilder.limit(limit);
        return this;
    }

    /**
     * Default scope.<br/>
     * Object shadows are created only from snapshots selected directly in the main JQL query.
     * <br/><br/>
     *
     * This query is fast (no additional queries are executed)
     * but shadows are shallow. Most object references <b>are nulled</b>.
     * <br/><br/>
     *
     * You can initialize referenced objects using the wider scopes:
     * child-value-object, commit-deep or deep+.
     */
    SHALLOW,

I think the problem here is that the documentation is clear to the ones who wrote it and know how everything fits together, but for someone just getting started, there's a lot of correlations that are not obvious because they don't know the full picture. I think it especially lacks "that means"-sections and examples for clarification.

Allow me to attempt to write a description for the limit that I feel would be clearer and would have helped me avoid that issue:

The limit filter limits the maximum amount of snapshots loaded during a Changes, Shadows or Snapshots request. By default, it is set to 100, which works well with small data structures. However, with large data structures, it is important to increase the limit to a more generous amount, as otherwise the requests might not return the desired amount of information. Since all requests rely on Snapshots in order to generate their output, the limit affects all three types of requests.

For example, if a Shadows request would result in the loading of more Snapshots than specified by the limit, the result might be that some versions are not returned, such as :

V5.0
V4.0
V1.0

Due to the way that Javers works, it will always return the earliest and the latest version correctly, even if it means exceeding the limit. After that, Javers will attempt to re-construct versions in order from latest to earliest until it exceeds the limit, at which point it will stop after the version where it exceeded the limit.

The limit can currently be set as high as 2147483647. There is currently no way to disable the limit completely. There is currently also no way to apply a limit to the number of Changes or Versions to load.

Overall, while working with Javers, I mostly got the feeling that the documentation is actually too short, does not go into detail enough. What you have now is a good overview and introduction to Javers, but it lacks in-depth sections that help with the problems one tends to run into when actually working with the thing. =^,~'=

@Kira-Cesonia this is the Open Source project, writing good docs is very hard, very time consuming and very boring to most developers. I don;t have time to write and maintain book-scale docs. Docs in Javers are concise and will stay concise. I will accept your changes to javadoc for the limit() method but it must be short and preferably based on some examples.
