PR Summary

StudyService#importStudyWithCaseImportAction

Reconstructs a study from a previously exported archive (TreeExportInfos): the node tree and all of its root networks, in one call.

  • The node tree only references modificationGroupUuids — it has no dependency on any imported network — so it is built synchronously, atomically with the StudyEntity itself (StudyService#createStudyEntityWithTree), duplicating each node's modification group via NetworkModificationService#duplicateModificationsGroup. Default study parameters (computation parameters, network visualization, spreadsheet config, workspaces config) are created the same way as for a normal study creation — that logic was extracted out of ConsumerService so both paths share it instead of duplicating it.
  • Each root network's case import, on the other hand, genuinely takes time and involves external HTTP calls, so it stays asynchronous: every root network — including what would be "the first" one — is attached via the existing ROOT_NETWORK_CREATION flow (StudyService#createRootNetworkRequest), exactly like adding an extra root network to an already-existing study. No special-casing of "the first" root network is needed anymore.
  • Each root network request runs in its own transaction (invoked through the self proxy) and its own try/catch: one root network failing to be requested (bad case, case-server error, name/tag clash, …) is logged and skipped, and does not roll back the study, the tree, or the other root networks already requested.
  • emitStudyCreationFinished is emitted once, after every root network has been attempted, not before — so it never fires ahead of a rollback caused by something later in the same call.
  • An empty rootNetworks list is rejected (NOT_FOUND) before anything is created — no orphaned study left behind on that path.
  • NodeTreeExportInfos.nodeType is validated up front for each node (BAD_NODE_TYPE on missing/invalid values) before duplicating its modification group, so malformed input never triggers the external side effect first.

This intentionally does not reuse the existing STUDY_CREATION case-import flow: that flow is hardwired to create exactly one root network and a fixed default tree (root + N1) in a single bundled async step, which doesn't fit an arbitrary imported tree plus an arbitrary number of root networks. Decoupling tree creation (fast, local, no async dependency) from root network attachment (slow, async, already has a battle-tested mechanism) removes the need for any pending-state hand-off across the async gap — no new database column, no JSON blob, no new CaseImportAction.

Covered by ImportStudyTest (happy path with 2 root networks, root-network-failure resilience, invalid node type, empty root network list).

How can I continue?

After more reviews become available, a review can be triggered using the @coderabbitai review command as a PR comment. Alternatively, push new commits to this PR.

To avoid repeated limits, reduce automatic review volume by pausing incremental auto-reviews earlier, using label-based review opt-in, excluding WIP or generated PR titles, or requesting reviews manually when the PR is ready. If your team needs uninterrupted high-volume reviews, an organization admin can enable usage-based reviews.

How do review limits work?

CodeRabbit enforces per-developer PR review limits for each organization. Most developers receive the normal plan review availability.

For paid Pro and Pro+ PR reviews, CodeRabbit uses adaptive limits for sustained high-volume activity. When a developer's recent PR review activity reaches the 95th percentile or higher among CodeRabbit users, additional reviews become available more gradually as earlier reviews age out of the rolling window.

🌐 Web query:

Spring ContentDisposition filename(String) escaping quotes RFC 5987 encoding behavior

💡 Result:

In Spring's ContentDisposition API, the handling of filenames depends on which builder method is used [1][2]. 1. Filename (Standard): When using builder.filename(String filename), Spring formats the value as a quoted-string according to RFC 2616 (Section 2.2) [1][2]. Any double-quote characters (") present in the filename are automatically escaped with a backslash () to ensure the header remains valid (e.g., "foo"bar.txt" becomes "foo\"bar.txt") [1][2]. 2. Filename* (RFC 5987): When using builder.filename(String filename, Charset charset), Spring encodes the filename according to RFC 5987 [1][3]. This method supports UTF-8, ISO-8859-1, and US-ASCII [1][3]. In this mode, the filename is not simply escaped but encoded as a series of percent-encoded characters (e.g., utf-8''filename.txt) [3]. RFC 5987 encoding is specifically designed to handle characters outside the US-ASCII range and is the recommended approach for internationalized filenames [4]. Spring documentation notes that RFC 5987 encoding should not be used for "multipart/form-data" requests, as per RFC 7578 and RFC 5987 itself [1][5]. For best compatibility, modern implementations often provide both parameters (filename and filename*) in the header, allowing legacy recipients to fall back to the standard quoted filename [4].

Streaming would avoid buffering whole cases in the heap.

getCaseContent returns ResponseEntity<byte[]>, so the complete case file is held in memory. StudyExportService.exportCaseFile then copies it again during gzip decompression before writing it to disk. Peak heap use is a multiple of the case size, per case and per concurrent export. Network case files can reach hundreds of megabytes.

Consider a streaming variant that writes directly to the target path, for example restTemplate.execute(url, HttpMethod.GET, null, response -> ...) with a ResponseExtractor that copies response.getBody() into the file.

Do not create the study from a client-supplied UUID.

treeExportInfos.studyUuid() comes straight from the request body. createStudyEntityWithTree passes it to studyRepository.save(StudyEntity.builder().id(studyUuid)...). For an id that already exists, JPA merges the row instead of inserting a new one. A caller can therefore post an archive whose studyUuid matches another user's study and overwrite that study's parameter references, monoRoot, and voltage-init parameters, then attach new root networks and nodes to it.

The endpoint also performs no permission check, unlike StudyExportService.exportStudy, which calls directoryService.checkPermission(...).

Generate a fresh UUID for the imported study, or reject the request when the UUID already exists.

🛡️ Proposed fix
-        StudyEntity studyEntity = createStudyEntityWithTree(treeExportInfos.studyUuid(), userId, treeExportInfos.nodeTree());
+        // never trust the study id carried by the archive
+        StudyEntity studyEntity = createStudyEntityWithTree(UUID.randomUUID(), userId, treeExportInfos.nodeTree());

@ghazwarhili, the comment context is outdated, but the reported behavior remains in the current revision.

At Line 3100, importStudyWithCaseImportAction still passes treeExportInfos.studyUuid() to createStudyEntityWithTree. At Lines 3122-3124, that method persists a StudyEntity with the supplied UUID. The import endpoint also has no authorization check before it calls the service.

I will keep this finding open.

    Validates imported root networks, sorts them by index, creates the study tree, verifies cases, submits root-network creation requests, logs per-root-network failures, and emits study-creation completion.

  • Lines 3123–3150 — createStudyEntityWithTree
    Creates a study with default computation and configuration parameters, creates the root modification node, recursively imports child nodes, and indexes study metadata.

  • Lines 3151–3171 — createNodeRecursively
    Recursively reconstructs exported modification nodes. It duplicates referenced modification groups, creates nodes with NOT_BUILT status by default, and processes descendants.

  • Lines 3173–3220 — default configuration helpers
    Attempt to duplicate user-profile network visualization, spreadsheet, and workspace configurations; on failure, log the error and fall back to system defaults or return null.

211-215: 📐 Maintainability & Code Quality | 🔵 Trivial | 💤 Low value

Separate the case-server base URI setup from the parameter stub helper.

stubDefaultParametersCreation sets caseServerBaseUri by reflection. That assignment is unrelated to default parameters. A reader who adds a new test cannot tell that this helper is also required to route case-server calls to WireMock.

Move the base URI assignment into a dedicated setup step, or rename the helper to state both responsibilities.

♻️ Proposed refactor
-    private void stubDefaultParametersCreation() throws Exception {
-        ReflectionTestUtils.setField(caseService, "caseServerBaseUri", wireMockServer.baseUrl());
+    private void setCaseServerBaseUri() {
+        ReflectionTestUtils.setField(caseService, "caseServerBaseUri", wireMockServer.baseUrl());
+    }
+
+    private void stubDefaultParametersCreation() throws Exception {
+        setCaseServerBaseUri();
         wireMockStubs.userAdminServer.stubGetUserProfile(USER_ID);
         setupCreateParametersStubs();
     }

Persist the exported root-network order.

RootNetworkService.createRootNetwork appends each completed root network to StudyEntity.rootNetworks, which uses @OrderColumn. Store the exported index in RootNetworkRequestEntity and apply it when creation completes. Add a test with reverse completion order.
