📝 Walkthrough

Walkthrough

The change adds a study-tree import endpoint and service, preserves imported root-network order, transfers computation parameters, handles asynchronous root-network completion, and streams case content during export.

Changes

Study tree import

Layer / File(s) Summary
Import contracts and study reconstruction
src/main/java/org/gridsuite/study/server/controller/StudyController.java, src/main/java/org/gridsuite/study/server/dto/..., src/main/java/org/gridsuite/study/server/service/StudyImportService.java, src/main/java/org/gridsuite/study/server/service/StudyService.java, src/main/java/org/gridsuite/study/server/service/common/ComputationParametersService.java, src/test/java/org/gridsuite/study/server/studycontroller/ImportStudyTest.java
The API accepts TreeExportInfos. The import service recreates the study tree, modification groups, default configurations, and computation parameters. Tests cover valid imports and validation failures.
Root-network ordering and completion
src/main/java/org/gridsuite/study/server/repository/..., src/main/java/org/gridsuite/study/server/service/ConsumerService.java, src/main/java/org/gridsuite/study/server/service/RootNetworkService.java, src/main/resources/db/changelog/..., src/test/java/org/gridsuite/study/server/studycontroller/ImportStudyTest.java
The database stores root-network order. Import requests use a dedicated action. Consumer events remove requests and check import completion.
Export parameters and case content
src/main/java/org/gridsuite/study/server/service/CaseService.java, src/main/java/org/gridsuite/study/server/service/StudyExportService.java, src/main/java/org/gridsuite/study/server/service/StudyService.java, src/main/java/org/gridsuite/study/server/service/common/ComputationParametersService.java, src/test/java/org/gridsuite/study/server/studycontroller/TreeExportTest.java, src/test/java/org/gridsuite/study/server/utils/wiremock/ComputationServerStubs.java
Exports include computation parameters. Case content is streamed to disk and gzip content is decompressed during export. Tests cover compressed content and parameter requests.

Count only requests that belong to the study import. insertCreationRequest stores both ordinary and import requests as RootNetworkAction.ROOT_NETWORK_CREATION. checkFinishedStudyImport therefore counts both types. The creation guard does not reject requests while rootNetworkOrder indicates an active import. If an ordinary request remains when the last import request completes, the count stays nonzero. The ordinary completion path does not call checkFinishedStudyImport, so the import can remain unfinished. Store an import-specific discriminator on the request and filter this count by it.

Path Traversal

Reachability: External
Exploitability: Moderate
CWE: CWE-22 — Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')

Constrain imported case names before writing export files.

CaseInfos.caseName is copied from the import request without validation. caseDir.resolve(caseName) accepts absolute paths and .. segments, so Files.newOutputStream(caseFile) can write outside the temporary export directory. Normalize the resolved path and reject it unless it starts with the normalized caseDir.
