…n-org#9091) When a tool (Query Tool, View/Edit Data, etc.) opens a connection for a server whose password was not saved, it relies on the password cached on the server manager. If that cached password is unavailable, the tool prompts for it. The entered password was POSTed to the connect_server endpoint, which short-circuited with "Server connected" whenever the server's primary connection was already established -- silently discarding the entered password. The tool's own connection therefore still had no password and re-prompted immediately, producing an infinite prompt loop in which the re-entered password appeared to be rejected. Cache the entered password on the server manager (encrypted) in that short-circuit path so the tool's connection can reuse it. The password overwrites any cached value, so a regenerated short-lived cloud auth token (AWS RDS IAM / Azure Entra) takes effect immediately.

WalkthroughThis pull request extracts the password from Query Tool requests and, when the server's primary connection is already established and a crypt key is available, encrypts and stores the password on the server manager to avoid repeated password prompts; includes tests and a release-note entry.

37-64: ⚡ Quick winConsider adding a JSON data scenario for complete coverage.
The stack context indicates that
_cache_manager_password_from_requestshould extract passwords from "request form or JSON," but all current scenarios only test the form data path. Consider adding a scenario that supplies the password viarequest.data(JSON) instead ofrequest.formto ensure both extraction paths are covered.📝 Suggested JSON scenario
+ ('When a password is supplied via JSON it is encrypted and cached', dict( + form_data={}, + json_data={'password': LONG_TOKEN}, + crypt_key_present=True, + expect_cached=True, + )),Then update line 77 to:
- mock_request.data = None + mock_request.data = getattr(self, 'json_data', {})
Note: The RUF012 warning about mutable class attributes is a false positive. The

- Around line 2708-2739: The function _cache_manager_password_from_request
currently calls json.loads(request.data) outside the try/except, which can raise
JSONDecodeError and crash the endpoint; move the JSON parsing into the existing
try/except (or add a small try/except around json.loads) so that invalid JSON is
treated as a no-op and the function returns silently; ensure you catch
json.JSONDecodeError (or Exception) and return early, keeping
manager._update_password(encrypt(...)) and manager.update_session inside the try
block so they only run with valid parsed data.

Move request-body JSON parsing inside the try/except so malformed request data is treated as a silent no-op (logged and swallowed) rather than propagating a JSONDecodeError and turning the connect_server endpoint's 'Server connected' response into a 500. Add a regression test scenario for the malformed-JSON case. Addresses CodeRabbit review feedback on pgadmin-org#10073.

Pull request overview
Fixes an infinite password re-prompt loop affecting Query Tool (and other tool-specific connections) when a server password is not saved, by caching the user-entered password on the ServerManager even when the primary connection is already established.
Changes:
- Cache the password from the
connect_serverrequest on theServerManager(encrypted) in the “already connected” short-circuit path. - Add unit tests covering caching, overwriting, and no-op scenarios (including malformed JSON handling).
- Document the fix in the v9.16 release notes.

Summary
Fixes an infinite password-prompt loop in the Query Tool (and other tools that open their own connections) for servers whose password was not saved — most visibly reported with long, short-lived cloud auth tokens used as the password (AWS RDS IAM, Azure Entra).
Root cause
When a tool such as the Query Tool opens a connection for a server whose password is not saved, it relies on the password cached on the
ServerManager. If that cached password is unavailable, the tool returns428and the UI prompts for the password. The entered password is POSTed to thesqleditor.connect_serverendpoint.connect_servershort-circuits with"Server connected"whenever the server's primary connection is already established — and in doing so silently discards the password the user just entered. The tool's own connection therefore still has no password and re-prompts immediately, producing an infinite loop in which the re-entered password appears to be rejected.Fix
In that short-circuit path, cache the entered password on the
ServerManager(encrypted) so the tool's connection can reuse it. The password overwrites any previously cached value, so a regenerated short-lived token takes effect immediately rather than the loop retrying a stale/expired one.The change is confined to the
connect_serverendpoint via a small helper; it is a no-op when no password is supplied or the encryption key is unavailable.Test plan
test_cache_manager_password.py(5 scenarios): password supplied is encrypted and cached; an existing cached password is overwritten; no-ops when the password is absent, empty, or the crypt key is missing. The cached value is verified to decrypt back to the original token intact.test_new_connection_dialogstill passes.pycodestyleclean.Note for reviewers
Several reporters (and maintainers) could not reproduce the original symptom in every environment, and a length/content correlation in the thread remains unexplained. This change definitively breaks the prompt loop and makes a correctly re-entered password take effect, matching the primary reported symptom. I've asked the reporters on the issue for their server mode / worker count / workspace-restore details in case a complementary fix (more reliable
manager.passwordpersistence) is also warranted.Closes #9091
