[dataimport] Fix case when extid is text in use_extid_as_cwuri() Extid can be bytes or text. This avoid AttributeError: 'str' object has no attribute 'decode'

[doc] fix key used in the hook example The hook's regid is check_no_subsidiary_cycle.

[doc] set_operation has been replaced by add_data See the changelog https://cubicweb.readthedocs.io/en/3.26/changes/changelog/#id14

[doc] check_cycle is a standard function

[doc] fix several typos

[pkg] make cubicweb[crypto] depends on pycryptodome instead of pycrypto pycrypto isn't maintained anymore, the last release 2.6.1 is from 2014. Use the drop-in replacement fork pycryptodome instead. pycryptodome is packaged in debian starting from stretch-backports.

[crypto] Encode unicode strings in _cypherer() pycrypto accept both bytes or string but pycryptodome, which will be introduced in next changeset, doesn't accept this. For backward compatibility, encode unicode strings in _cypherer()

[ldapfeed] FIX: Unique Key violation when synchronizing with LDAPfeed What was happening ================== The bug appears when ldapfeed tries to insert a user while another user exists exists with a different source. Simple use case to reproduce: - create a local user in cubicweb (source=system) - sync with ldap - ldapfeed will stop complaining user already exists. Without next patch the test MUST fail with message: cubicweb/server/sources/native.py:714: UniqueTogetherError The ldapfeed is thus stopped ignoring any further ldap entries. The proposal ============ Prior to this patch, the insertion was trying to create all CWUser with the computed login from eeimporter.extid2eid (method process of DataFeedLDAPAdapter). When a CWUser existed with a different cw_source ("system" for user created with cubicweb for instance), it created a conflict. To avoid collisions, in the extentities_generator method a bypass was added at the insertion layer. Prior to insertion the absence of the computed login is checked on a list of all existing login from a different source. If collision is detected, we skip the ldap record. By short circuiting at the CWUser entity insertion level we also avoid to treat CWGroup and EmailAddress related to this user. Hence ensuring a behaviour that will not break existing instances. (conservative approach: faced with ambiguity better do nothing than guess). An error message is added stating explicitly the conflict.

Skip tests for ldapsource with python >= 3.7 Until someone works on fixing these, this should make our CI green again. I tried to use setupModule() to check for python version, but pre_setup_database() is apparently called even when a SkipTest exception is raised there. So handle this in that method.

Flake8 crypto module

Make crypto module python3-compatible * Remove usage of unicode() and decode the base64-encoded string in encrypt(); * Encode the string received in decrypt() as (I supposed) it should come from the result of encrypt(). Add tests for this module along the way.

[mod] make ViolatedConstraint actually display useful information Move from: (Pdb++) raise some_exception *** ViolatedConstraint: To: (Pdb++) raise some_exception *** ViolatedConstraint: constraint 'cstr56c2ab4b3154f21d08b067742ce5bd9d' is being violated by the query 'ALTER TABLE cw_Bibliography ADD CONSTRAINT cstr56c2ab4b3154f21d08b067742ce5bd9d CHECK(cw_item_type IN ('journalArticle', 'note', 'book', 'thesis', 'film', 'web page', 'manuscrit', 'tapuscrit'))'. You can run the inverted constraint on the database to list the problematic rows. And save hours of debugging to actually understand what is going on.

Fix flake8 errors/warnings about import in cubicweb/_exceptions.py We either ignore errors in case of name re-exports and drop re-exports from old backwards compatibility. We fix the only occurrence of NoSelectableObject being imported from cubicweb in tests and update the import to use lgc instead.

[changelog] document pyramid.ini automatic generation

Flake8 cubicweb/pyramid/test/test_hooks.py

[pyramid/doc] bad docstring

[pyramid/misc] remove useless variable

[pyramid/test] add test for pyramid.ini generation

Added tag 3.26.10 for changeset 74cc5de1ee6c

[pkg] Version 3.26.10

Move CWSchemaTC to RQLExpressionTC The test actually doesn't require a cubicweb schema, except for testing EmailAdress which is out of scope of the test (testing RQLExpression.transform_has_permission()). Just move the test in existing RQLExpressionTC inheriting from TestCase and rename the tests to be more explicit.

[skeleton] Drop py27 tox environment Since we dropped py2 support from cubicweb, it does not make much sense to keep it in skeleton from now on.

DeprecationWarning: In future versions of Waitress clear_untrusted_proxy_headers will be set to True by default. You may opt-out by setting this value to False, or opt-in explicitly by setting this to True. Source: https://docs.pylonsproject.org/projects/waitress/en/stable/arguments.html?highlight=clear_untrusted_proxy_headers > This tells Waitress to remove any untrusted proxy headers ("Forwarded", > "X-Forwared-For", "X-Forwarded-By", "X-Forwarded-Host", "X-Forwarded-Port", > "X-Forwarded-Proto") not explicitly allowed by trusted_proxy_headers. According to grep we don't use any of those headers so let's turn it on for security reasons.

DeprecationWarning: The default pickle serializer is deprecated as of Pyramid 1.9 and it will be changed to use pyramid.session.JSONSerializer in version 2.0. Explicitly set the serializer to avoid future incompatibilities . See "Upcoming Changes to ISession in Pyramid 2.0" for more information about this change. As describe here https://docs.pylonsproject.org/projects/pyramid/en/1.10-branch/narr/sessions.html#pickle-session-deprecation use a serializer that fallback on pickle if needed to avoid impacting users.

[pyramid/enh] generate pyramid.ini "create" and on "pyramid" command if needed

DeprecationWarning: The SafeConfigParser class has been renamed to ConfigParser in Python 3.2. This alias will be removed in future versions. Use ConfigParser directly instead.

Account for new psycopg2 exception classes mapping From psycopg2 >= 2.8, specific exceptions are raised corresponding to postgresql errors. E.g. a CheckViolation exception is raised instead of a generic IntegrityError previously when a constraint violation occurs. The way we intercept database errors, especially for constraint violation, is not compliant with that because we do not catch subclasses of IntegrityError in native source's doexec() method. We fix this by checking for the presence of IntegrityError error in exception class's mro. This is still overcomplicated and clumsy, because we still use string comparison, but this is the best we can do as far as I know. (A better fix would be 'isinstance(ex, IntegrityError)' but we have no engine-independent error classes, so this is not possible. Something like sqlalchemy's DBAPI Errors [1] might help: https://docs.sqlalchemy.org/en/latest/errors.html#dbapi-errors)

[cubicweb-ctl] remove "cubicweb-ctl wsgi" command following pyramid standardization

Use secure hash algorithm in WebConfiguration.sign_text Fix: PendingDeprecationWarning: HMAC() without an explicit digestmod argument is deprecated. The default hash algorithm used by hmac.new is md5. As of today, md5 is so weak that it's the equivalent of plaintext and can't be considered to be secured at all. Therefor, we switch to a secure hash algorithm. The rational for choosing sha3_512 is: * the recommended algorithm is at least sha_256 * the stronger, the more secured and sha3_512 is the stronger available * thinking about the future this should keep this part of the code safe long enough before people think about checking it again You can read more about choosing a secure hash algorithm in the NIST recommendations https://csrc.nist.gov/Projects/Hash-Functions/NIST-Policy-on-Hash-Functions This code modification should normally be transparent since check_text_sign is exactly this code 'self.sign_text(text) == signature' and that sign_text is only used in combination with it. The only impact is that the hash is going to move from 32 char to 128 which might make html page a bit bigger and that sha3_512 is slow to compute (which is a good thing for security)

[devtools/testlib] avoid hidding AttributeError in create_user() commit() might raise a AttributeError too. Use getattr(req, 'cnx', req) instead, which is a form already used to get the real cnx in some code: cubicweb/rset.py:577: cnx = getattr(self.req, 'cnx', self.req) cubicweb/schema.py:353: with getattr(_cw, 'cnx', _cw).security_enabled(read=False): We could use if hasattr(req, 'commit') here too but it lead to 3 additionals lines. Maybe we should have commit() and rollback() on cubicweb.web.request.ConnectionCubicWebRequestBase too ?

[README] add testing instructions

Add pytest-subtests to dev requirements This pytest plugin adds support for unittest's TestCase.subTest (for Python >= 3.4). Since we we now only support python3 and since we use a fair amount of these, let's benefit of better reporting by using this plugin.

[test] use unittest.mock instead of mock library Now that we use Python 3 only, this is possible.

Drop python2 support This mostly consists in removing the dependency on "six" and updating the code to use only Python3 idioms. Notice that we previously used TemporaryDirectory from cubicweb.devtools.testlib for compatibility with Python2. We now directly import it from tempfile.
