Linking to Python for Windows CE
I've just been tasked with porting our desktop embedded Python support onto our existing CE offering. I've managed to compile the Python sources and have produced an armdbg420\python23.lib file. When I come to link to the Python library though from our one of our DLLs, I am getting the following unresolved externals: --- embedded.obj : error LNK2019: unresolved external symbol "__declspec(dllimport) int __cdecl WinCE_fclose(void *)" (__imp_?WinCE_fclose@@[EMAIL PROTECTED]) referenced in function "unsigned long __cdecl PythonThread(void *)" (?PythonThread@@[EMAIL PROTECTED]) embedded.obj : error LNK2019: unresolved external symbol __imp_LoadLibraryU referenced in function "unsigned long __cdecl PythonThread(void *)" (?PythonThread@@[EMAIL PROTECTED]) embedded.obj : error LNK2019: unresolved external symbol "__declspec(dllimport) void * __cdecl WinCE_fopen(char const *,char const *)" (__imp_?WinCE_fopen@@[EMAIL PROTECTED]) referenced in function "void * __cdecl OpenScriptFile(unsigned short *)" (?OpenScriptFile@@[EMAIL PROTECTED]) --- python23.lib does have entries for WinCE_fopen (part of wince-compatibility.c) when looking at the lib file using dumpbin (all are undecorated). Have I missed some vital step in producing it? Just to clarify my environment, I am producing a PocketPC 2003 application that embeds Python, scripts are launched within our application with script output displayed in our own output window. We also provide our own Python extension library. All works on ok on the desktop version. Any help would gratefully appreciated. Thanks. Martin -- http://mail.python.org/mailman/listinfo/python-list
Re: Linking to Python for Windows CE
Sorry, false alarm. It turned out one of my own files was using fopen/fclose and this was upseting things. After removing those it linked fine.

RegEx conditional search and replace
Sorry, yet another REGEX question. I've been struggling with trying to get a regular expression to do the following example in Python: Search and replace all instances of "sleeping" with "dead". This parrot is sleeping. Really, it is sleeping. to This parrot is dead. Really, it is dead. But not if part of a link or inside a link: This parrot is sleeping. Really, it is sleeping. to This parrot is sleeping. Really, it is dead. This is the full extent of the "html" that would be seen in the text, the rest of the page has already been processed. Luckily I can rely on the formating always being consistent with the above example (the url will normally by much longer in reality though). There may though be more than one link present. I'm hoping to use this to implement the automatic addition of links to other areas of a website based on keywords found in the text. I'm guessing this is a bit too much to ask for regex. If this is the case, I'll add some more manual Python parsing to the string, but was hoping to use it to learn more about regex. Any pointers would be appreciated.

Many thanks for that, the function method looks very useful. My first
working attempt had been to use the regex to locate all links. I then looped
through replacing each with a numbered dummy entry. Then safely do the
find/replaces and then replace the dummy entries with the original links. It
just seems overly inefficient.

I agree, but luckily in this case the HREF will always be formated the same
as it happens to be inserted by another automated system, not a user. Ok it
be changed by the server but AFAIK it hasn't for the last 6 years. The text
in question apart from the links should be plain (not even is allowed I
think).
I'd read about back and forward regex matching and thought it might somehow
be of use here ie back search for the ""
but of course this would easily match in between two links.

Invalid thread state for this thread
I know this has been seen before but it is not making too much sense (after
reading many posts). It all appears to work fine but then dies after about
40 invocations.
My app has Python embedded, it is embedded as part of a dll which
initializes python and finalizes on load and unload (see below). When a
script needs to be run, I create a new thread, let the script complete and
close the thread.
The thread contains the following type arrangement:
PythonThread()
{
hScriptFile = OpenScriptFile(m_szActiveScript);
PyEval_AcquireLock();
pInterpreter = Py_NewInterpreter();
Py_SetProgramName(szModuleFileName);
PyRun_SimpleFile(hScriptFile,m_szActiveScript);
PyErr_Clear();
Py_EndInterpreter(pInterpreter);
PyEval_ReleaseLock();
}
This appears to work fine accept that after around 30-40 invocations I
always get the "Invalid thread state for this thread". ie the app and dll
stay loaded and I click my "run" button manually about 40 times. In this
test it is a simple "hello world" type script. The size of the script does
not appear to matter.
The dll is coded something like this:
DllLoad()
{
Py_Initialize();
PyEval_InitThreads();
m_mainThreadState = PyThreadState_Get();
PyEval_ReleaseLock();
}
DllUnload() (not called as part of this test)
{
PyEval_AcquireLock();
PyThreadState_Swap(m_mainThreadState);
Py_Finalize();
}
The app has been designed to allow a second interpreter to run independently
(thus the need for multiple thread support) and this also appears to work
fine, but for this test only this one thread was used. I have a compiled
version of 2.4.2.
Any ideas would be appreciated.

Re: Invalid thread state for this thread
Just in case anyone else has seen this problem, after upgrading to 2.4.4 the
problem appears to have resolved itself.

py2exe, library.zip and python.exe
I have converted a Python script using py2exe and have it set to not bundle or compress. The result is my exe and all the support files including library.zip (exactly as planned - nice job py2exe). Question: My py2exe application needs to be able to execute extra copies of python.exe. I have placed python.exe in the same directory. It obviously picks up the main python24.dll but how can I configure things so that it would use the same library.zip for all the library files? This would save me having two sets of files. (The py2exe application happens to be a twisted server app running as a service which has the ability to launch python scripts as a logged on user) Thanks, Martin. -- http://mail.python.org/mailman/listinfo/python-list

When python.exe is loaded, sys.path already had python24.zip in it so changing the specified library in py2exe from the default libary.zip to python24.zip solved it!
