We need to handle adding when interface mapping returns a null target method. There’s several different spots we need to handle this at. Added an IL-only test case to verify this scenario is working. 21361 1 Medium Cannot write bytes to files 22302 1 Medium help() on a CLR string[] fails with a stack trace 22966 1 Medium Problem with re module/groupindex property, incompatibility with CPython Add filtering for the special named groups we have to insert. 23143 bin(n > System.Int32.MaxValue) broken We’re going through our helpers for string formatting which don’t add the – before the value and don’t expect negative values in general. Assert we have positive values, make the helpers which can’t handle negatives private, and define internal APIs w/ a simple signature which does it all. 3740 0 Medium Trivial: Overloaded properties (indexers) not handled by IronPython IronPython\2.6 This works via the same get_ method that C# supports. Adding test case to verify it keeps working.

This adds a new DLL to the IronPython MSI and to the IronPython and DLR CodePlex releases. This is just adding their source code and updating our build and packaging infrastructure to include their new DLL. The only changes to their code were some #ifdef’s to support Silverlight builds and some updates to the .csproj files to support our numerous builds. This code is owned by them and has been reviewed by their team so I’m not looking for a code review for the new DLL. Once this is in I’ll be updating Igor’s prototype for sys.settrace support for IronPython and adding that.

55001 by IPyTeam	Jun 18 at 3:52 PM	17	-------------------------------------------------------------------------------- Changeset Id: 950981 Date: 6/17/2009 2:10:25 PM (dinov) Implements support for generic method type inference. Mostly a DLR outer layer change with some tweaks to IronPython and IronRuby. Python changes: We no longer need to eagerly detect when we’re calling a method w/ only generics. We also add support for inferring types for Lambda arguments based upon a Python Function’s arity. Finally there’s one fix where we make sure to create the correct kind DMO instead of just the base DynamicMetaObject type. A few tests are also updated as there are some minor changes in results when overloaded by both a generic method and a non-generic method. Finally lots of new tests are added. Ruby changes: Ruby’s MethodGroupInfo was doing MakeGenericMethod and then returning the generic method. But the types it’s passing in are all generic parameters – so the end result is Ruby produces a method for which .IsGenericMethodDefinition is false but it contains all of the original generic method parameters. Now we return the original target so IsGenericMethodDefinition remains true. Also updated MissingBlockArgBuilder so we can know that it doesn’t really prodive any parameters. Finally the small set of tests verifying exceptions are throw are updated to expect successful inference. DLR changes: This is the bulk of the changes. Added a new TypeInferer class which performs the actual type inference. Added a new CallFailureReason for noting when we failed to perform type inference. Updated the ArgBuilder’s so we can clone them w/ a new ParameterInfo. This is used for replacing the existing ArgBuilder’s built for the generic method w/ new ArgBuilders which have been specialized to the specific generic type. Fixed a couple of spots where we were creating base DynamicMetaObject’s instead of getting them from their values. Added support for MethodCandidate’s to track additional restrictions with themselves – this is necessary because the type inference can result in new type checks when inferring based ...

54862 by IPyTeam	Jun 16 at 3:53 PM	13	-------------------------------------------------------------------------------- Changeset Id: 947161 Date: 6/15/2009 5:30:14 PM (dinov) DLR outer ring only: Fix case insensitivity of SymbolIDs. Our current case insensitive story for SymbolIDs doesn’t really work. There are 2 problems: 1. Case insensitive IDs won’t compare equal to normal case sensitive IDs. This means you can’t create a case insensitive ID and use it for lookup in an IAttributesCollection. a. This is just updating SymbolID to do the right comparisons and hashing and getting rid of some useless APIs here. 2. When we store the IDs in the SymbolTable there is no way to disambiguate between an all upper case symbol and the “invariant” symbol. a. Here we need a separate table to store the invariant IDs. I’ve also gotten rid of the ToUpper call and replaced it with a case invariant dictionary. Now we have a separate table for the invariant IDs and it stores the latest case-version. There’s also a bunch of cleanup – replaced the magic numbers with 2 constants and added some missing locking on our ToString and Contains APIs. (Shelveset: SymbolIdFix;REDMOND\dinov | SNAP CheckinId: 8701) -------------------------------------------------------------------------------- Changeset Id: 946342 Date: 6/15/2009 10:42:17 AM (dinov) 4566 codecs.escape_encode returns a string instead of a tuple and the string has the wrong value Fixed our implementation to match CPython 17541 IronPython compiler throws an exception on syntax warnings Replace throwing with a report to the warnings.showwarning function. We no longer set the error code on warnings either. 1717 ironpython issues less number of "syntaxwarning"'s compared to cpython We report less warnings because we throw on the 1st warning. We no longer throw and instead actually report a warning. Also updated the error messages to match CPython. 21483 str.ljust does not properly handle width=int.MinValue If we get a negative value return the original string I’m also adding some restrictions which are missing for purposes of x-lang interop. When VB is talking to us neither of us will restrict when we both should restrict. Python needs to restrict because we generate a type test, VB needs to restrict for whether it’s handling an IDMOP or not. (Shelveset: FixSyntaxWarningsFinal;REDMOND\dinov | SNAP CheckinId: 8694) -------------------------------------------------------------------------------- Changeset Id: 946270 Date: 6/15/2009 9:55:51 AM (dinov) Fixes various issues related to dir(). This change removes the get member names call site and replaces this with just a normal non-callsite based implementation of dir. It also fixes sorting of GetAttrNames in some cases so that a few tests had to be updated to handle the changed results. 22456 Unexpected instance variables on subclass when __dir__ implemented PythonType now adds all of the members (including non-string keys) and this is avoided when we do __dir__. Then PythonOps.GetAttrNames no longer needs to add non-string keys. 22832 dir(new-class) overlooks methods inherited from old-style classes PythonType updated to handle old-classes. This causes a number of tests (specifically one string formatting and a bunch of codecs tests) to start running that previously didn’t. I’ve disabled these tests and opened bugs. I’ve also added a start of the required codecs support but ifdef’d it out keep things simple here. 11883 Calling help() on a .NET Framework class causes it to show up twice in dir() output This seems to be fixed already – just adding a regression test 20957 dir(expando_inst) doesn't show dyn members We now manifest a __dir__ method on non-Python IDynamicMetaObjectProvider instances. Then our normal handling for __dir__ picks this up and gets the member name.s 22536 dir() fails for some generic CLR types We need to handle the case where the Type is a generic type definition which does not return a name.

54584 by IPyTeam	Jun 12 at 3:52 PM	64	-------------------------------------------------------------------------------- Changeset Id: 941816 Date: 6/11/2009 9:22:19 AM (dinov) Fixes these two issues: 22692 - compile() incompatibility with CPython 12907 - Missing PyCF_DONT_IMPLY_DEDENT compile Flag Also moves all error reporting out of the AST generator and into the Parser. This will enable total lazy transformation of the trees if we want to do it. It also means that editors using our Parser for syntax highlighting will see all errors instead of missing things like break outside of a loop. This is just removing the places in transform into explicit virtual calls (CheckAssign, CheckDelete, CheckAugmentedAssign) that we call and if we get a string back we report that string as the error. Most of the change is about tracking blank lines and reporting them from the tokenizer as NL tokens. This isn’t what the documentation says we should be doing (all blank lines are to be ignored) but it matches what CPython’s tokenize module is doing and presumably what CPython’s actual tokenizer is doing as well. Certainly it’s hard to imagine otherwise how code that only differs by new lines could report different exceptions. So do this the tokenizer now needs to keep track whether it just gave out a newline and if so when it will give out another one it should instead give out a NL token. Don’t imply dedent is also updated to look at this state and yield a real newline (if we don’t have one, for example consider “def f(): return 2”) and then yield the pending dedent(s). Also there’s a fun little hack to match CPython’s behavior where it differs on how it reports errors w/ “compile()” vs an imported file. If we are doing a “compile” (we have interactive code or statements) then re-indenting at turns into an error ("def Foo():\n\n pass\n\n "). But if this is just some random source file that we’re bringing in via import then this is perfectly fine. I’ve also updated most of the test_syntax tests to run on both CPython and IronPython – we still differ on some of the errors.

Changes to a number of test files were necessary as a result (e.g., method.py) - supports "--help", "--plan", and "--no_testing" flags. --plan is a new feature used to generate test plans based on pydoc found in the tests. --no_testing does what its name implies and is useful with --plan iptest.assert_util: support the new --no_testing flag iptest.runner: added changes necessary to support the --plan flag interop.net: moved the most recent IronPython .NET Interop Test Plan directly into this test package as pydoc comments (Shelveset: NETPLAN;REDMOND\dfugate | SNAP CheckinId: 8511)

When we have a mixed interpreted/compiled stack we’re getting the wrong result. This is because of few reasons: 1. We need to clear the stack back trace we’ve calculated for Python when we re-throw the exception otherwise we’ll re-use it. I’ve made the rethrow in WithStatement now throw through our helper and updated the interpreter to do nothing special w/ repros making it closer to the compiled code path. 2. Over in ExceptionHelpers we are combining the saved stacks + the new stacks in the incorrect order when reverse frames is true. This causes us to get confused and lose frames. 20634 hex_codec needs to be imported before hex decode can happen 15428 ".". does not generate a SyntaxError in interactive sessions 15348 TypeError thrown for IronPython.Compiler.Ast.ErrorExpression cast failure in interactive sessions 20302 codecs.lookup errors with uppercase encoding names 20051 Re-raising exception causes loss of traceback 22259 len(buffer) is incorrect 4565 Support all encodings CPython does for _codecs.encode and _codecs.decode 21929 os.listdir does not accept empty path 20603 Trivial: os.walk(‘’) doesn’t work 2169 test_isinstance incompatibilities with CPython 17235 dir(System.ArgIterator) broken 20039 struct.pack('L', -1) is stricter than in CPython 19484 Error with timeit.py module 19005 Strange issues with BOM? 10816 -X:MaxRecursion N<=1 broken 19278 Confusing Error Message when using in operator 13912 TypeError: Could not create instance of <type 'Visual'> Improve the error message – we now include that the type is abstract Also assigning to MemoryHolder’s size as caught in code review, fixing build.bat to run w/ frames enabled.
