fix(115_open): clean parent path before lookup

[syscc]

Summary / 摘要

• Normalize the parent path returned by path.Split before requesting 115 folder metadata.

• Restore nested directory creation in the 115 Open driver by avoiding a trailing slash that the 115 API interprets as an empty directory name.

• No public API, configuration, storage format, or dependency changes.

Testing / 测试

• go test ./...
• Manual test / 手动测试:
  • macOS arm64, Go 1.26.5.
  • Ran from source with go run main.go --data <test-data> server --debug --log-std.
  • Reproduced the failure against beta commit d90ef1e, then verified the fix against current upstream main (bacd0870) plus this commit.
  • Used the same 115 Open storage for the before/after requests. The temporary directories were removed after verification.

Failure log before the fix

Creating a directory directly below the mount root succeeded:

POST /api/fs/mkdir
Content-Type: application/json

{"path":"/115/__openlist_mkdir_probe_20260722"}

HTTP/1.1 200
{"code":200,"message":"success","data":null}

Creating its child failed before Mkdir was reached:

POST /api/fs/mkdir
Content-Type: application/json

{"path":"/115/__openlist_mkdir_probe_20260722/child_ascii"}

HTTP/1.1 500
{"code":500,"message":"failed to check if dir exists: failed to get obj: code: 20001, message: 目录名称不能为空。","data":null}

The first lookup of the missing child returned an empty data array as expected. The fallback then sent the parent path with the trailing slash produced by path.Split:

POST https://proapi.115.com/open/folder/get_info
Content-Type: application/x-www-form-urlencoded

path=/__openlist_mkdir_probe_20260722/

HTTP/1.1 200
{"state":false,"message":"目录名称不能为空。","code":20001,"data":[]}

Sending the same parent path without the trailing slash returned the folder metadata successfully. Sensitive file IDs and pick codes are omitted:

POST https://proapi.115.com/open/folder/get_info
Content-Type: application/x-www-form-urlencoded

path=/__openlist_mkdir_probe_20260722

HTTP/1.1 200
{"state":true,"message":"","code":0,"data":{"file_name":"__openlist_mkdir_probe_20260722","file_category":"0","...":"redacted"}}

Verification log after the fix

Both root and nested directory creation succeeded:

POST /api/fs/mkdir
{"path":"/115/__openlist_mkdir_fix_verify_20260722"}

{"code":200,"message":"success","data":null}

POST /api/fs/mkdir
{"path":"/115/__openlist_mkdir_fix_verify_20260722/二级目录测试"}

{"code":200,"message":"success","data":null}

Listing the parent confirmed that the child was created:

{"code":200,"message":"success","data":{"content":[{"name":"二级目录测试","is_dir":true}],"total":1,"...":"omitted"}}

Cleanup succeeded, and the follow-up lookup confirmed removal:

{"code":200,"message":"success","data":null}
{"code":500,"message":"failed to get obj: object not found","data":null}

Additional checks:

• gofmt -d drivers/115_open/driver.go produced no output.
• git diff --check passed.
• The full test suite was not run locally; repository CI is expected to perform the broader build checks.
