From 161fd0542425dc9afa336dcb0675f56b3e1b0b55 Mon Sep 17 00:00:00 2001 From: Ruben Pollan Date: Tue, 14 Jun 2016 19:06:45 +0200 Subject: [feat] improve duplicated active documents fixup Mostly for private keys we want to keep the latest one in the keyring. It would be desirable to check with one is set in nicknym, but this will need a big refactor that I'm not sure if it's worth it just for that. - Related: #6658, #8059 --- keymanager/changes/next-changelog.txt | 1 + keymanager/src/leap/keymanager/openpgp.py | 35 ++++++++--- .../src/leap/keymanager/tests/test_keymanager.py | 22 ++++--- .../src/leap/keymanager/tests/test_openpgp.py | 67 +++++++++------------- 4 files changed, 68 insertions(+), 57 deletions(-) diff --git a/keymanager/changes/next-changelog.txt b/keymanager/changes/next-changelog.txt index 91ca8bd..a2ab4fb 100644 --- a/keymanager/changes/next-changelog.txt +++ b/keymanager/changes/next-changelog.txt @@ -12,6 +12,7 @@ Features ~~~~~~~~ - `#8031 `_: Remove support for multiple key types. - `#8068 `_: make get_all_keys aware of active addresses. +- `#6658 `_: Improve duplicated active documents fixup. - `#1234 `_: Description of the new feature corresponding with issue #1234. - New feature without related issue number. diff --git a/keymanager/src/leap/keymanager/openpgp.py b/keymanager/src/leap/keymanager/openpgp.py index 8658e9c..98ce464 100644 --- a/keymanager/src/leap/keymanager/openpgp.py +++ b/keymanager/src/leap/keymanager/openpgp.py @@ -47,8 +47,8 @@ from leap.keymanager.documents import ( TYPE_ADDRESS_PRIVATE_INDEX, KEY_UIDS_KEY, KEY_FINGERPRINT_KEY, + KEY_PRIVATE_KEY, KEY_REFRESHED_AT_KEY, - KEY_LAST_AUDITED_AT_KEY, KEY_SIGN_USED_KEY, KEY_ENCR_USED_KEY, KEY_ADDRESS_KEY, @@ -268,8 +268,8 @@ class OpenPGPScheme(object): '1' if private else '0') keys = [] + fp = lambda doc: doc.content[KEY_FINGERPRINT_KEY] for active in active_docs: - fp = lambda doc: doc.content[KEY_FINGERPRINT_KEY] fp_keys = filter(lambda k: fp(k) == fp(active), key_docs) if len(fp_keys) == 0: @@ -770,6 +770,7 @@ class OpenPGPScheme(object): return self._repair_docs(doclist, cmp_key, log_key_doc) + @defer.inlineCallbacks def _repair_active_docs(self, doclist): """ If there is more than one active doc for an address try to self-repair @@ -779,23 +780,39 @@ class OpenPGPScheme(object): all the deletions are completed :rtype: Deferred """ + keys = {} + for doc in doclist: + fp = doc.content[KEY_FINGERPRINT_KEY] + private = doc.content[KEY_PRIVATE_KEY] + try: + key = yield self._get_key_doc_from_fingerprint(fp, private) + keys[fp] = key + except Exception: + pass + def log_active_doc(doc): logger.error("\t%s: %s" % (doc.content[KEY_ADDRESS_KEY], doc.content[KEY_FINGERPRINT_KEY])) def cmp_active(d1, d2): - res = cmp(d1.content[KEY_LAST_AUDITED_AT_KEY], - d2.content[KEY_LAST_AUDITED_AT_KEY]) - if res != 0: - return res - + # XXX: for private keys it will be nice to check which key is known + # by the nicknym server and keep this one.
