* Convert every string specifying a DN into a DN object
* Every place a dn was manipulated in some fashion it was replaced by
the use of DN operators
* Add new DNParam parameter type for parameters which are DN's
* DN objects are used 100% of the time throughout the entire data
pipeline whenever something is logically a dn.
* Many classes now enforce DN usage for their attributes which are
dn's. This is implmented via ipautil.dn_attribute_property(). The
only permitted types for a class attribute specified to be a DN are
either None or a DN object.
* Require that every place a dn is used it must be a DN object.
This translates into lot of::
assert isinstance(dn, DN)
sprinkled through out the code. Maintaining these asserts is
valuable to preserve DN type enforcement. The asserts can be
disabled in production.
The goal of 100% DN usage 100% of the time has been realized, these
asserts are meant to preserve that.
The asserts also proved valuable in detecting functions which did
not obey their function signatures, such as the baseldap pre and
post callbacks.
* Moved ipalib.dn to ipapython.dn because DN class is shared with all
components, not just the server which uses ipalib.
* All API's now accept DN's natively, no need to convert to str (or
unicode).
* Removed ipalib.encoder and encode/decode decorators. Type conversion
is now explicitly performed in each IPASimpleLDAPObject method which
emulates a ldap.SimpleLDAPObject method.
* Entity & Entry classes now utilize DN's
* Removed __getattr__ in Entity & Entity clases. There were two
problems with it. It presented synthetic Python object attributes
based on the current LDAP data it contained. There is no way to
validate synthetic attributes using code checkers, you can't search
the code to find LDAP attribute accesses (because synthetic
attriutes look like Python attributes instead of LDAP data) and
error handling is circumscribed. Secondly __getattr__ was hiding
Python internal methods which broke class semantics.
* Replace use of methods inherited from ldap.SimpleLDAPObject via
IPAdmin class with IPAdmin methods. Directly using inherited methods
was causing us to bypass IPA logic. Mostly this meant replacing the
use of search_s() with getEntry() or getList(). Similarly direct
access of the LDAP data in classes using IPAdmin were replaced with
calls to getValue() or getValues().
* Objects returned by ldap2.find_entries() are now compatible with
either the python-ldap access methodology or the Entity/Entry access
methodology.
* All ldap operations now funnel through the common
IPASimpleLDAPObject giving us a single location where we interface
to python-ldap and perform conversions.
* The above 4 modifications means we've greatly reduced the
proliferation of multiple inconsistent ways to perform LDAP
operations. We are well on the way to having a single API in IPA for
doing LDAP (a long range goal).
* All certificate subject bases are now DN's
* DN objects were enhanced thusly:
- find, rfind, index, rindex, replace and insert methods were added
- AVA, RDN and DN classes were refactored in immutable and mutable
variants, the mutable variants are EditableAVA, EditableRDN and
EditableDN. By default we use the immutable variants preserving
important semantics. To edit a DN cast it to an EditableDN and
cast it back to DN when done editing. These issues are fully
described in other documentation.
- first_key_match was removed
- DN equalty comparison permits comparison to a basestring
* Fixed ldapupdate to work with DN's. This work included:
- Enhance test_updates.py to do more checking after applying
update. Add test for update_from_dict(). Convert code to use
unittest classes.
- Consolidated duplicate code.
- Moved code which should have been in the class into the class.
- Fix the handling of the 'deleteentry' update action. It's no longer
necessary to supply fake attributes to make it work. Detect case
where subsequent update applies a change to entry previously marked
for deletetion. General clean-up and simplification of the
'deleteentry' logic.
- Rewrote a couple of functions to be clearer and more Pythonic.
- Added documentation on the data structure being used.
- Simplfy the use of update_from_dict()
* Removed all usage of get_schema() which was being called prior to
accessing the .schema attribute of an object. If a class is using
internal lazy loading as an optimization it's not right to require
users of the interface to be aware of internal
optimization's. schema is now a property and when the schema
property is accessed it calls a private internal method to perform
the lazy loading.
* Added SchemaCache class to cache the schema's from individual
servers. This was done because of the observation we talk to
different LDAP servers, each of which may have it's own
schema. Previously we globally cached the schema from the first
server we connected to and returned that schema in all contexts. The
cache includes controls to invalidate it thus forcing a schema
refresh.
* Schema caching is now senstive to the run time context. During
install and upgrade the schema can change leading to errors due to
out-of-date cached schema. The schema cache is refreshed in these
contexts.
* We are aware of the LDAP syntax of all LDAP attributes. Every
attribute returned from an LDAP operation is passed through a
central table look-up based on it's LDAP syntax. The table key is
the LDAP syntax it's value is a Python callable that returns a
Python object matching the LDAP syntax. There are a handful of LDAP
attributes whose syntax is historically incorrect
(e.g. DistguishedNames that are defined as DirectoryStrings). The
table driven conversion mechanism is augmented with a table of
hard coded exceptions.
Currently only the following conversions occur via the table:
- dn's are converted to DN objects
- binary objects are converted to Python str objects (IPA
convention).
- everything else is converted to unicode using UTF-8 decoding (IPA
convention).
However, now that the table driven conversion mechanism is in place
it would be trivial to do things such as converting attributes
which have LDAP integer syntax into a Python integer, etc.
* Expected values in the unit tests which are a DN no longer need to
use lambda expressions to promote the returned value to a DN for
equality comparison. The return value is automatically promoted to
a DN. The lambda expressions have been removed making the code much
simpler and easier to read.
* Add class level logging to a number of classes which did not support
logging, less need for use of root_logger.
* Remove ipaserver/conn.py, it was unused.
* Consolidated duplicate code wherever it was found.
* Fixed many places that used string concatenation to form a new
string rather than string formatting operators. This is necessary
because string formatting converts it's arguments to a string prior
to building the result string. You can't concatenate a string and a
non-string.
* Simplify logic in rename_managed plugin. Use DN operators to edit
dn's.
* The live version of ipa-ldap-updater did not generate a log file.
The offline version did, now both do.

Calling a LDAP{Add,Remove}ReverseMember with an empty reverse_member
caused an internal error, because empty values are converted to None,
which is then iterated.
Use an empty list instead of None (or other false falues, of which we
only use the empty list).
https://fedorahosted.org/freeipa/ticket/2681
Have the test suite check error messages.
Since XMLRPC doesn't give us structured error information, just
compare the resulting text.
Fix messages that tests expect to cause.
Minor changes:
Make netgroup-mod's NotFound message consistent with other objects
and methods.
In test_automember_plugin, test with nonexistent automember rules
of both types, instead of nonexistent users.
https://fedorahosted.org/freeipa/ticket/2549
Some of our tests used unintended extra options, or options with
misspelled, wrongly copy-pasted or otherwise bad names. These are
ignored, so the intended argument was treated as missing. The test
itself can still pass but may be rendered ineffective or fragile.
This only fixes those of such errors that appear in the test suite.
Fixing code in the framework and actual rejecting of unknown
arguments is deferred for later (ticket #2509).
Splitting on commas is not an idempotent operation:
'a,b\,c' -> ('a', 'b,c') -> ('a', 'b', 'c')
That means we can't do it when the call is forwarded, so this is only
done on the CLI. The UI already sends values as a tuple.
Replace escaping in the csv parser with quoting. Quoted strings can have
embedded commas instead of having to escape them. This prevents the csv
parser from eating all escape characters.
Also, document Param's csv arguments, and update tests.

There may be cases, for whatever reason, that an otherwise illegal
entry gets created that doesn't match the criteria for a valid
user/host/group name. If this happens (i.e. migration) there is no way
to remove this using the IPA tools because we always applied the name
pattern. So you can't, for example, delete a user with an illegal name.
Primary keys are cloned with query=True in PKQuery which causes no
rules to be applied on mod/show/find. This reverts a change from commit
3a5e26a0 which applies class rules when query=True (for enforcing no
white space).
Replace rdnattr with rdn_is_primary_key. This was meant to tell us when
an RDN change was necessary to do a rename. There could be a disconnect
where the rdnattr wasn't the primary key and in that case we don't
need to do an RDN change, so use a boolean instead so that it is
clear that RDN == primary key.
Add a test to ensure that nowhitespace is actually enforced.

We have a larger goal of replacing all DN creation via string
formatting/concatenation with DN object operations because string
operations are not a safe way to form a DN nor to compare a DN. This
work needs to be broken into smaller chunks for easier review and
testing.
Addressing the unit tests first makes sense because we don't want to
be modifying both the core code and the tests used to verify the core
code simultaneously. If we modify the unittests first with existing
core code and no regressions are found then we can move on to
modifying parts of the core code with the belief the unittests can
validate the changes in the core code. Also by doing the unittests
first we also help to validate the DN objects are working correctly
(although they do have an extensive unittest).
The fundamental changes are:
* replace string substitution & concatenation with DN object
constructor
* when comparing dn's the comparision is done after promotion
to a DN object, then two DN objects are compared
* when a list of string dn's are to be compared a new list is
formed where each string dn is replaced by a DN object
* because the unittest framework accepts a complex data structure of
expected values where dn's are represeted as strings the unittest
needs to express the expected value of a dn as a callable object
(e.g. a lambda expression) which promotes the dn string to a DN
object in order to do the comparision.
The pairwise grouping used to form RDN's and AVA's proved to be
confusing in practice, this patch removes that functionality thus
requiring programmers to explicitly pair attr,value using a tuple or
list.
In addition it was discovered additional functionality was needed to
support some DN operations in freeipa. DN objects now support
startswith(), endswith() and the "in" membership test. These functions
and operators will accept either a DN or RDN.
The unittest was modified to remove the pairwise tests and add new
explicit tests. The unittest was augmented to test the new
functionality. In addition the unittest was cleaned up a bit to use
common utilty functions for improved readabilty and robustness.
The documentation was updated.
fix test_role_plugin use of DN to avoid pairwise grouping
Introduce a comma into a privilege name to assure we can handle
commas.
Commas must be escaped for some parameters, add escape_comma() utility
and invoke it for the necessary parameters.
Utilize a DN object to properly construct a DN and most importantly to
allow equality testing beween the DN we expect and the one
returned. This is necessary because a DN can be encoded according to
different encoding syntaxes all of which are valid. DN objects always
decode from their input. DN objects can test for equality between DN's
without being affected by DN encoding.
Add a equality callback for the dn in the expected dict. When the test
framework tests for equality between the expected value and the
returned value it will call back into a function we provide which will
convert the returned dn into a DN object. An equality test is then
performed between two DN objects. This is the only way to properly
compare two dn's.
We collected the failures but didn't report it back. This changes the
API of most delete commands so rather than returning a boolean it returns
a dict with the only current key as failed.
This also adds a new parameter flag, suppress_empty. This will try to
not print values that are empty if included. This makes the output of
the delete commands a bit prettier.

The changes include:
* Change license blobs in source files to mention GPLv3+ not GPLv2 only
* Add GPLv3+ license text
* Package COPYING not LICENSE as the license blobs (even the old ones)
mention COPYING specifically, it is also more common, I think
https://fedorahosted.org/freeipa/ticket/239
The new model is based on permssions, privileges and roles.
Most importantly it corrects the reverse membership that caused problems
in the previous implementation. You add permission to privileges and
privileges to roles, not the other way around (even though it works that
way behind the scenes).
A permission object is a combination of a simple group and an aci.
The linkage between the aci and the permission is the description of
the permission. This shows as the name/description of the aci.
ldap:///self and groups granting groups (v1-style) are not supported by
this model (it will be provided separately).
This makes the aci plugin internal only.
