How do I build a .NET 2.0 version of IronPython from source?
  


VS 2008 can build a .NET 2.0 version (and VS Express should work I 
think), but I'm pretty sure that VS 2005 won't be able to build it.


I built from the latest sources last night, it is up at:

[IronPython] Building stand alone executable

2008-08-27 Thread cephire

Hi:
The program that I've written works well when using the ipy command. I
tried to compile it as a standalond executable using pyc.py. It
produces an executable without any error. When I try to execute the
executable, nothing happens; There is no error message; nothing. How
can I debug? How can I produce a executable?

Here are some info:
IronPython and IronMath are present in the same directory
I'm using the below command to produce the executable:

ipy pyc.py /main:MainForm.py /out:mysecs.exe /target:winexe

Begining of the program looks like this:

import clr
clr.AddReference('System')
clr.AddReference('System.Windows.Forms')
clr.AddReference('System.Drawing')
#unmanaged code
clr.AddReference('mySecs')
#external dlls
clr.AddReference('SourceGrid')
clr.AddReference("System.Data")
clr.AddReference('System.Data.SQLite')

import System
from System import *
from System.Windows.Forms import *
from System.Drawing import *
from System.Text import StringBuilder
from System.Diagnostics import Process
from System import Environment
from System import DateTime

from System.Data.SQLite import *

Any help is appreciated. Thank you,

Try compiling as a console application rather than a windows executable 
and when you run it you will get the error message output to the console.

Re: [IronPython] Building from source

2008-08-27 Thread Curt Hagenlocher

You need a certificate to sign the assembly if you want a strong name -- and
of course any certificate that Michael has or generates won't have the same
key signature as the certificate we use to sign here.

For IronRuby, we've modified the export script so that building from source
will no longer delay-sign the assembly but just leave it unsigned.  Is this
something that people would find useful for our regular source drops?  If
so, I can try to cajole Dave into changing the script.  He probably doesn't
have enough work to do anyway ;).

Re: [IronPython] Building from source

2008-08-27 Thread Dave Fugate

Hi, the source updates to CodePlex's TFS repository and the source zip files 
should not even include the ability to delay-sign  assemblies.  I've just 
verified this is still the case with the update to CodePlex yesterday.  Which 
IronPython binaries are you trying to run and what error message are you 
getting?

The other thing is you shouldn't need Visual Studio 2008 to build the latest 
IronPython sources from CodePlex's TFS repository.  You just need .NET 3.5 
installed and the following should work:
pushd %WHEREEVER%\IronPython-38029\IronPython_Main\Src
C:\Windows\Microsoft.NET\Framework\v3.5\MSBuild IronPython.sln

Re: [IronPython] Building from source

2008-08-27 Thread Dave Fugate

Yes, .NET 3.5's msbuild can be used to generate IronPython (2.x) binaries that 
will run under .NET 2.0 SP1 in the manner I showed below.  This is what we use 
for generating IronPython Alpha/Beta/etc releases.  Please note that you won't 
be able to run IronPython 2.x without SP1 of .NET 2.0 (or alternatively .NET 
3.5) installed though.

It hasn't been possible to build IronPython.sln under Visual Studio 2005 for a 
couple of release cycles.

You need a certificate to sign the assembly if you want a strong name -- and of 
course any certificate that Michael has or generates won't have the same key 
signature as the certificate we use to sign here.

For IronRuby, we've modified the export script so that building from source 
will no longer delay-sign the assembly but just leave it unsigned.  Is this 
something that people would find useful for our regular source drops?  If so, I 
can try to cajole Dave into changing the script.  He probably doesn't have

Thanks Dave, I have SP1 and I'll figure out how to build 2.x binaries with 3.5. 
Do you have any idea about:

Yes, .NET 3.5's msbuild can be used to generate IronPython (2.x) binaries that 
will run under .NET 2.0 SP1 in the manner I showed below.  This is what we use 
for generating IronPython Alpha/Beta/etc releases.  Please note that you won't 
be able to run IronPython 2.x without SP1 of .NET 2.0 (or alternatively .NET 
3.5) installed though.

It hasn't been possible to build IronPython.sln under Visual Studio 2005 for a 
couple of release cycles.

[IronPython] Return value for ADODB .Execute() call?

2008-08-27 Thread Vernon Cole

I've hit my next sticking point in porting adodbapi.


try:
import win32com.client
def Dispatch(dispatch):
return win32com.client.Dispatch(dispatch)
win32 = True
except ImportError:  # implies running on IronPython
from System import Activator, Type
def Dispatch(dispatch):
type = Type.GetTypeFromProgID(dispatch)
return Activator.CreateInstance(type)
win32 = False#implies IronPython
# [... much later ...]
class Cursor(object):
# ...
  def _executeHelper(self,operation,etc):
self.cmd=Dispatch("ADODB.Command")
# ...
   self.cmd.CommandText=operation
# ...
adoRetVal = self.cmd.Execute()
if win32:
rs=adoRetVal[0]
try:
self.rowcount = rs.RecordCount
except:
self.rowcount = adoRetVal[1]
else:  # iron Python
rs = adoRetVal
try:
self.rowcount = rs.RecordCount
except:
# HOW DO I GET THE ROW COUNT ? ? ?
self.rowcount= -1

It appears that, when called from VB, the Execute method takes an optional
agument.
>From w3schools.com:

ADO Execute Method
--
[image: Command Object Reference] Complete Command Object
Reference
--

The Execute method executes the query, SQL statement or procedure specified
in the CommandText property of the Command object.

The results are stored in a new Recordset object if it is a row-returning
query. A closed Recordset object will be returned if it is not a
row-returning query.
Syntax for row-returning

Set rs=objcommand.Execute(ra,parameters,options)

  Syntax for non-row-returning

objcommand.Execute ra,parameters,options


 Parameter Description  ra  Optional. Returns the number of records affected
by a query. For a row-returning query, use the RecordCount property of the
Recordset object to count of how many records are in the object.  parameters
 Optional. Parameter values passed with an SQL statement. Used to change,
update, or insert new parameter values into the Parameters Collection.  options
Optional. Sets how the provider should evaluate the CommandText property.
Can be one or more
CommandTypeEnumor
ExecuteOptionEnumvalues.
Default is adCmdUnspecified.
We can't pass the "ra" parameter in python, so pywin32 returns a
tuple with the recordset and the number of records.

How do I retrieve the number of records (for a non-row-returning query) in
Iron?

I am using IPCE-r7. i'm importing logging using import logging. and as

logging is a Python standard library module. IPCE includes the Python 
standard library - and probably adds it to the path for you when you run 
stuff with the IPCE version of ipy.exe.


You may be able to setup the IRONPYTHONPATH environment variable to 
point to the standard library directory (not 100%  certain that apps 
compiled with Pyc will honour IRONPYTHONPATH but it is easy enough to 
find out) - or your program can add this to sys.path yourself. 
Alternatively you could work out exactly which standard library modules 
you are relying on and compile them into your application as well.

Presumably, Execute expects you to pass a VT_I4 | VT_BYREF so that it
can store the value in the reference.  If this were for a CLR API,
you'd pass an int reference by using a variable of type
clr.Reference[int](). I don't know that this will work for COM, but I
assume that it would:

ra = clr.Reference[int]()
self.cmd.Execute(ra)
recordCount = ra.Value

If you create a Windows Application it detaches from the console so you 
will never see any error message. It is likely that you are missing a 
module or assembly that you rely on (do you use any standard library 
modules?).

Create it as a console application and run it from the command line on 
the target machine and you will see the error message.

Re: [IronPython] Return value for ADODB .Execute() call?

2008-08-27 Thread Shri Borde

Using clr.Reference[int] should work if ra is an in-out (VT_BYREF) parameter. 
Note that not many OleAut APIs use VT_BYREF. Jscript does not support in-out 
parameters and the API would not be usable form Jscript.

We do have the option of returning a tuple with the recordset and the number of 
records, just like pywin32, by checking the ITypeInfo if any of the parameters 
are VT_BYREF. We even had this working at some point. However, we have decided 
not to use ITypeInfo to check the type of parameters in order to keep the code 
paths the same when there is no typelib available.

If you run into lots of APIs with in-out parameters, do let us know. Its 
something we could revisit for IPy 2.1. I will collect a list of such APIs in 
the "Known Issues" section in my blog at 
http://blogs.msdn.com/shrib/archive/2008/07/30/idispatch-support-on-in-ironpython-beta-4.aspx
 for tracking purposes.

Using clr.Reference will always work now and in the future, with or without 
typelibs being available.

you'd pass an int reference by using a variable of type

[IronPython] What is .AppendChunk expecting?

2008-08-27 Thread Vernon Cole

Dear miracle workers:
  This may actually be the last failed unittest for adodbapai. Progress has
been remarkable.
Can you help with one more?

Situation: filling in the parameter list for an ADO execute.  The second
parameter (parameter 1) is a python "buffer" to be loaded into a binary(4)
column.
"elem" contains the value of the parameter.
"p" is the parameter object.
Pywin32 uses p.AppendChunk successfully to pass the buffer to SQL, but Iron
objects:


DatabaseError:

This will probably need to be a string.  I don't think we do any automatic
conversions of buffer objects for CLR or COM calls.

Re: [IronPython] What is .AppendChunk expecting?

2008-08-27 Thread Vernon Cole

I tried both
p.AppendChunk(str(elem))
and
p.AppendChunk(unicode(elem))
both of which work, but then the execution fails with:

   File "C:\Program Files\IronPython 2.0
Beta4\lib\site-packages\adodbapi\adodbapi.py", line 675, in _executeHelper
rs = self.cmd.Execute(ra)
 EnvironmentError: The field is too small to accept the amount of data you
attempted to add.  Try inserting or pasting less data.
-- on command: "INSERT INTO tblTemp (fldId,fldData) VALUES (?,?)"
-- with parameters: (2, )

which lead me to believe that I'm not giving .AppendChunk() the argument it
expects.

I even tried
p.Value = elem
which results in:
 StandardError: Exception has been thrown by the target of an invocation.

Re: [IronPython] What is .AppendChunk expecting?

2008-08-27 Thread Curt Hagenlocher

Two more ideas:

1) Try passing a list of numbers.  You can trivially get this from the
buffer by saying
a = map(lambda c: ord(c), buf)
2) Try passing a BCL array of bytes.  This is almost as easy:
import System
a = System.Array[System.Byte](map(lambda c: ord(c), b))

Re: [IronPython] What is .AppendChunk expecting?

2008-08-27 Thread Shri Borde

I think you are going to need Curt's solution #2 and explicitly create a "byte 
array".

Let us know if that works. If it does, we could also consider adding to 
IronPython.Runtime.PythonBuffer (the class which implements 
buffer) an implicit 
conversion operator to "byte array". With a few tweaks to 
System.Scripting.Com.VarEnumSelector, we could get to a point where you should 
be able to just do 
"p.AppendChunk(elem)"
 and have elem converted from a 
buffer to "VT_ARRAY | 
VT_I1"

Situation: filling in the parameter list for an ADO execute.  The second 
parameter (parameter 1) is a python "buffer" to be loaded into a binary(4) 
column.
"elem" contains the value of the parameter.
"p" is the parameter object.
Pywin32 uses p.AppendChunk successfully to pass the buffer to SQL, but Iron 
objects:


DatabaseError:

 TypeError: Specified cast is not valid.
-- on command: "INSERT INTO tblTemp (fldId,fldData) VALUES (?,?)"

What coercion should be supplied to make AppendChunk happy to accept the buffer 
contents without trying to cast it?

  again.

2) implemented as:
 from System import Array,Byte
 a = Array[Byte](map(lambda c: ord(c),elem))
 p.AppendChunk(a)
gives:
 SystemError: Unexpected VarEnum 8209.

which is new, at least.

8209 is 0x2011, which is indeed VT_UI1 | VT_ARRAY.  Do you know as
what type this argument ends up getting passed when you call this
through pythoncom?

System.Scripting.Com.VarEnumSelector.GetManagedMarshalType does not deal with 
VT_ARRAY. Curt, I believe we need to add code to handle this.

Vernon, could you open a CodePlex bug please?

Btw, for now, you could workaround the problem by using Type.InvokeMember 
(http://msdn.microsoft.com/en-us/library/66btctbe.aspx) directly as such:

import clr
from System.Reflection import BindingFlags
bindingFlags = BindingFlags.InvokeMethod | BindingFlags.Instance | 
BindingFlags.Public | BindingFlags.IgnoreReturn
t = clr.GetClrType(type(p))
from System import Array, Byte
a = Array[Byte](map(lambda c: ord(c),elem))
t.InvokeMember("AppendChunk", bindingFlags, None, p, Array[object]([a])
