[IronPython] clr.CompileSubclassTypes restrictions on list of types
Hi, Are there any restrictions placed on the list of types that can be passed to CompileSubclassTypes? We are having issues with a clr.AddReference(DllContainingSubclasses) being very slow, so are trying to split the compiled subclasses across multiple dlls to indicate progress between the loading of these dlls. However, when trying to compile a partial list of types we get the following error: Traceback (most recent call last): File c:\buildshare\gitrepo\precompile_subclasses.py, line 40, in c:\buildsha re\gitrepo\precompile_subclasses.py TypeError: : can only extend one CLI or builtin type, not both Microsoft.Scripti ng.Runtime.Extensible`1[[System.Double, mscorlib, Version=2.0.0.0, Culture=neutr al, PublicKeyToken=b77a5c561934e089]] (for IronPython.Runtime.Types.PythonType) and IronPython.Runtime.SetCollection (for IronPython.Runtime.Types.PythonType) Any help is much appreciated, Tom ___ Users mailing list Users@lists.ironpython.com http://lists.ironpython.com/listinfo.cgi/users-ironpython.com
Re: [IronPython] clr.CompileSubclassTypes restrictions on list of types
The only restrictions are the normal restrictions that Python has regarding inheritance. In this case it looks like you're hitting that you cannot inherit from more than one base type w/ a different layout. Basically it looks like you're trying to pre-compile the equivalent of: class c(float, set): pass Which isn't legal in Python so my guess is there is an issue w/ the way you split them up. -Original Message- From: users-boun...@lists.ironpython.com [mailto:users- boun...@lists.ironpython.com] On Behalf Of Tom Wright Sent: Tuesday, November 10, 2009 9:39 AM To: Discussion of IronPython Subject: [IronPython] clr.CompileSubclassTypes restrictions on list of types Hi, Are there any restrictions placed on the list of types that can be passed to CompileSubclassTypes?

Re: [IronPython] clr.CompileSubclassTypes restrictions on list of types
Thanks the reply, Could you clarify slightly what you mean by the Python's normal restrictions. I was guessing the restriction might be something like: When compiling a list of types, if the list contains a class B which inherits from A then A must be contained in the list. The interesting thing here is that the call to CompileSubclassTypes works when we pass it one huge list of types, but not when we call if repeatedly with smaller lists.

Re: [IronPython] clr.CompileSubclassTypes restrictions on list of types
The restrictions are per-subclass so for example you cannot inherit from both a list and tuple. The reason here is that list and tuple both have their own independent layout in memory and there's no relationship between them. Or in your case it's set and float. CompileSubclassTypes takes an arbitrary number of parameters and those can be either a type (which gets compiled) or they can be a tuple of types which specify the collection of base types. The latter form is generally useful for including .NET interfaces. So clr.CompileSubclassTypes(foo, (set, float)) will fail as this is specifying that you want 1 class which inherits from both set and float. But you can do clr.CompileSubclassTypes(foo, set, float) and this specifies what you want 2 types, one that inherits from set and float. Or you can do: clr.CompileSubclassTypes(foo, (set, ), (float, )) and again that'll work because it's specifying 2 different base types. -Original Message- From: users-boun...@lists.ironpython.com [mailto:users- boun...@lists.ironpython.com] On Behalf Of Tom Wright Sent: Tuesday, November 10, 2009 10:08 AM To: Discussion of IronPython Subject: Re: [IronPython] clr.CompileSubclassTypes restrictions on list of types Thanks the reply, Could you clarify slightly what you mean by the Python's normal restrictions.

As for the question at hand, though :) I'm not in blanket agreement here. I'd agree for some releases to be valid dependency points, but things like RCs, betas, obsoleted third-level versions -- not really. In the first two cases, those are bleeding-edge releases. If you take a dependency on them, expect to bleed. In the latter case, I wouldn't expect API differences, or other breaking changes unless they represented critical bug fixes.

Re: [IronPython] IronPython 2.6 RC 1 Release Hidden
You're right .. the problem *is* a developer taking dependencies on specific releases. Further, I contend that it's the developer taking dependencies on experimental releases. That's improper, and why we as an industry label such things with alpha, beta, RC and so forth. Each of those are warning signs of this may change, and you shouldn't depend on it yet. The low-level point releases, of course, represent (in theory) non-API fixes, and so the only dependency taken in those cases should not break, unless the dependency was on broken behavior in which case the end-user is more likely than not being sloppy. I have no qualms about them bleeding in that case. The years-long-betas of the *nix community notwithstanding, I'd as soon we stick to our guns regarding such things. Having to maintain (ie, support) n different versions is a tremendous burden. I myself had to maintain (no exaggeration) about 3 dozen different versions of the *same* product at one job, but there were other reasons that came to be. Would an image of a giant Monty Python foot stomping on the prior versions, with the caption the version you are requesting has been obsoleted and is no longer supported -- use at your own risk be an acceptable approach? :) From: users-boun...@lists.ironpython.com on behalf of Michael Foord Sent: Tue 11/10/2009 12:34 PM To: Discussion of IronPython Subject: Re: [IronPython] IronPython 2.6 RC 1 Release Hidden Keith J.

Re: [IronPython] IronPython 2.6 RC 1 Release Hidden
Hmm... I certainly don't suggest that the dynamic languages team *support* obsolete versions, but in my experience it is 'unusual' for an open source project to make previously released code / binaries *completely* unavailable - support notwithstanding. For Python itself I believe you can download the sources for version 0.9.1, but it isn't much of a maintenance burden these days... I don't see an upside to hiding code (or 'breaking things' as I like to put it) in quite the same way you do. :-) All the best, Michael Keith J. Farmer wrote: You're right .. the problem *is* a developer taking dependencies on specific releases. Further, I contend that it's the developer taking dependencies on experimental releases. That's improper, and why we as an industry label such things with alpha, beta, RC and so forth. Each of those are warning signs of this may change, and you shouldn't depend on it yet. The low-level point releases, of course, represent (in theory) non-API fixes, and so the only dependency taken in those cases should not break, unless the dependency was on broken behavior in which case the end-user is more likely than not being sloppy. I have no qualms about them bleeding in that case. The years-long-betas of the *nix community notwithstanding, I'd as soon we stick to our guns regarding such things. Having to maintain (ie, support) n different versions is a tremendous burden. I myself had to maintain (no exaggeration) about 3 dozen different versions of the *same* product at one job, but there were other reasons that came to be. Would an image of a giant Monty Python foot stomping on the prior versions, with the caption the version you are requesting has been obsoleted and is no longer supported -- use at your own risk be an acceptable approach? :) *From:* users-boun...@lists.ironpython.com on behalf of Michael Foord *Sent:* Tue 11/10/2009 12:34 PM *To:* Discussion of IronPython *Subject:* Re: [IronPython] IronPython 2.6 RC 1 Release Hidden Keith J.

I'd agree for some releases to be valid dependency points, but things like RCs, betas, obsoleted third-level versions -- not really. In the first two cases, those are bleeding-edge releases. If you take a dependency on them, expect to bleed. The problem is that if a developer has used (and depended on) APIs in a specific release of IronPython then the person who bleeds is likely to be an end user rather than the developer (who may have moved onto other things without updating their project). I don't have a problem with relegating obsolete releases to a small corner, but making them unavailable altogether is a high cost. Michael In the latter case, I wouldn't expect API differences, or other breaking changes unless they represented critical bug fixes. Again, I wouldn't want to support a dependency upon something horribly broken.

Re: [IronPython] Weird issue with codecs.BOM_UTF8
Hi Michael, I just verified the empty string theory that you mentioned and Python25\lib\codecs.py (comes with the standard library in Python 2.5) has the following defined: # UTF-8 BOM_UTF8 = '\xef\xbb\xbf' So it is not an empty string. Maybe I am approaching this wrong and you guys can provide me with an alternative way of doing this. I am trying to read a file and determine if the file is encoded in UTF-8 or not. The approach I took was to use python's built-in open function to read the text file into an array of strings and check if the first line starts with the UTF-8 byte order mark by using line.startswith(codecs.BOM_UTF8). As I noted below, this works fine in Python 2.5 but in IronPython it just keeps saying it found a UTF-8 BOM even though there is none present.

I just installed IronPython 2.0.3 and this is what I found: C:\C:\Program Files\IronPython 2.0.3\ipy.exe IronPython 2.0.3 (2.0.0.0) on .NET 2.0.50727.3603 Type help, copyright, credits or license for more information. import sys sys.path.append(r'D:\Python25\lib') import codecs lines = open(r'D:\Temp\text_file_without_utf8_bom.txt', 'r').readlines() print lines ['This is a text file without a UTF-8 BOM.\n', 'Line 2\n', 'Line 3'] lines[0].startswith(codecs.BOM_UTF8) True ^Z C:\ It returned 'True' even though the text file did not have a UTF-8 BOM.

In .NET it would be more normal to check for the BOM with bytes, as by the time you have a string you have (usually) decoded already. IronPython 2.X is a bit odd for the .NET framework in this respect. Michael

Re: [IronPython] .NET attributes for methods
Note that you will have to set __metaclass__ to ClrMetaclass, not ClrTypeMetaclass as in DevHawk's sample. I had changed the name of the type. The old name will cause a NameError, but maybe SL is hiding exceptions. Can you do o.GetType().GetFields() and display that on the page to inspect the object and also make sure that no exceptions were thrown?

Re: [IronPython] IronPython 2.6 RC 1 Release Hidden
Well, perhaps because I don't see the upside in breaking things, either.

One thing that seems to be missing from the hosting API discussion is talk about the ScriptRuntimeSetup classes.

I certainly don't suggest that the dynamic languages team *support* obsolete versions, but in my experience it is 'unusual' for an open source project to make previously released code / binaries *completely* unavailable - support notwithstanding. For Python itself I believe you can download the sources for version 0.9.1, but it isn't much of a maintenance burden these days...

That's improper, and why we as an industry label such things with alpha, beta, RC and so forth. Each of those are warning signs of this may change, and you shouldn't depend on it yet. The low-level point releases, of course, represent (in theory) non-API fixes, and so the only dependency taken in those cases should not break, unless the dependency was on broken behavior in which case the end-user is more likely than not being sloppy. I have no qualms about them bleeding in that case. The years-long-betas of the *nix community notwithstanding, I'd as soon we stick to our guns regarding such things. Having to maintain (ie, support) n different versions is a tremendous burden. I myself had to maintain (no exaggeration) about 3 dozen different versions of the *same* product at one job, but there were other reasons that came to be.

I'd agree for some releases to be valid dependency points, but things like RCs, betas, obsoleted third-level versions -- not really. In the first two cases, those are bleeding-edge releases. If you take a dependency on them, expect to bleed. The problem is that if a developer has used (and depended on) APIs in a specific release of IronPython then the person who bleeds is likely to be an end user rather than the developer (who may have moved onto other things without updating their project). I don't have a problem with relegating obsolete releases to a small corner, but making them unavailable altogether is a high cost. Michael In the latter case, I wouldn't expect API differences, or other breaking changes unless they represented critical bug fixes. Again, I wouldn't want to support a dependency upon something horribly broken.
