From 129467d00e57f6cce34a8a4dc8b8b0e4a9b5e6e9 Mon Sep 17 00:00:00 2001 From: drebs Date: Tue, 26 Apr 2016 00:48:25 -0300 Subject: [refactor] remove shared db locking from client Shared db locking was used to avoid the case in which two different devices try to store/modify remotelly stored secrets at the same time. We want to avoid remote locks because of the problems they create, and prefer to crash locally. For the record, we are currently using the user's password to encrypt the secrets stored in the server, and while we continue to do this we will have to re-encrypt the secrets and update the remote storage whenever the user changes her password. --- common/src/leap/soledad/common/errors.py | 61 -------------------------------- 1 file changed, 61 deletions(-) (limited to 'common/src') diff --git a/common/src/leap/soledad/common/errors.py b/common/src/leap/soledad/common/errors.py index 0b6bb4e6..76a7240d 100644 --- a/common/src/leap/soledad/common/errors.py +++ b/common/src/leap/soledad/common/errors.py @@ -70,67 +70,6 @@ class InvalidAuthTokenError(errors.Unauthorized): status = 401 -# -# LockResource errors -# - -@register_exception -class InvalidTokenError(SoledadError): - - """ - Exception raised when trying to unlock shared database with invalid token. - """ - - wire_description = "unlock unauthorized" - status = 401 - - -@register_exception -class NotLockedError(SoledadError): - - """ - Exception raised when trying to unlock shared database when it is not - locked. - """ - - wire_description = "lock not found" - status = 404 - - -@register_exception -class AlreadyLockedError(SoledadError): - - """ - Exception raised when trying to lock shared database but it is already - locked. - """ - - wire_description = "lock is locked" - status = 403 - - -@register_exception -class LockTimedOutError(SoledadError): - - """ - Exception raised when timing out while trying to lock the shared database. - """ - - wire_description = "lock timed out" - status = 408 - - -@register_exception -class CouldNotObtainLockError(SoledadError): - - """ - Exception raised when timing out while trying to lock the shared database. - """ - - wire_description = "error obtaining lock" - status = 500 - - # # SoledadBackend errors # u1db error statuses also have to be updated -- cgit v1.2.3
