Win32 package

[GoogleCodeExporter]

Which the possibility for future to make a package for Windows platform?

Using pygobject, pycairo, pygtk, py2exe and nsis as the installer is not
very difficult. But it has modules in pychess that they only function in Linux.

I've never developed for Windows, so I can't say for sure.
However I'm certain that windows would need an alternative engine system.
Perhaps first creating a such, and then take out bugs as they appear?

If you'd like to investigate the possibility, feel free to ask questions :)
Doesn't gnome-games run on windows? Or is it only Solaris..

Now, only Aisleriot port for Windows http://live.gnome.org/GnomeGames/Windows

I go to make the installer for the Windows, and report the problems that to 
appear.

I see.
Try out os.path.expanduser("~")
If it works, we can add:
os.environ["HOME"] = os.path.expanduser("~")
in the start script.

[GoogleCodeExporter]

I put os.environ["HOME"] = os.path.expanduser("~") in prefix.py and
conf_configParser.py ok.

1. Main.py:
from pychess.System import conf, glock
try:
    from pychess.System import gstreamer
except ImportError:
    print 'pygst don\'t installed'
    pass 

because I don't need porting gstreamer to windows.

the gettext problem (include in Main.py):
from pychess.System.prefix import addDataPrefix, getDataPrefix, isInstalled
import gettext, gtk.glade
if isInstalled():
    gettext.install("pychess", unicode=1)
    gtk.glade.bindtextdomain("pychess")
else:
    gettext.install("pychess", localedir=addDataPrefix("lang"), unicode=1)
    gtk.glade.bindtextdomain("pychess", addDataPrefix("lang"))
gtk.glade.textdomain("pychess")

win32 package first run lib/pychess/Main.py and the gettext in trunk/pychess.

const.py (getuid and getpwuid run only UNIX):
try:
    from os import getuid
    from pwd import getpwuid
    userdata = getpwuid(getuid())
    i = userdata.pw_gecos.find(',')
    if i >= 0:
        username = userdata.pw_gecos[i:]
    else: username = userdata.pw_name
    del userdata, i
except:
    pass

widgets/gamewidget.py (another gstreamer):
from pychess.System import glock, conf
try:
    from pychess.System import gstreamer

1) I don't think you should try...catch gstreamer in Main.py. Better put it in 
the
gstreamer module.

2) Can you try to explain the gettext problem again? Does the windows package 
run
Main.py before trunk/pychess?

3) http://aspn.activestate.com/ASPN/Cookbook/Python/Recipe/66314 seams to have a
solution for getting username on windows. Either use a try...catch or a "if 
'nt' in
sys.platform"

4) We could either make the windows version star slower, by removing some of the
asynchronous reading from the file, or perhaps the fcntl process locking could 
be
substituted by some of this: http://en.wikipedia.org/wiki/File_locking

5) The configParser.write problem, seams to merely be a HOME issue than an 
issue that
should be try...catched.

Just committed a minimal patch to start win32 support.
Now "python setup.py install" is ok on windows.

After starting it with "python pychess" in c:\Python25\scripts dir, it gives a
traceback telling that (the select) "module object has no attribute poll".

(Maybe the gstreamer module can be substituted with winsound module on win32.)

Original comment by gbtami on 25 Nov 2007 at 6:23

[GoogleCodeExporter]

Super. windsound sounds good.

An idea:
if sys.platform == "win32":
    from os.path import dirname, abspath
    python_path = os.path.join(dirname(abspath(sys.executable)), python")
else:
    python_path = searchPath("python")
Perhaps it would be nicer to add the win32 fix in searchPath rather than where 
it is
used?

On the poll thing, does anybody know how windows poll pipes, if their select 
and poll
only works on sockets?

Hi All

 I did a windows installer for a Python project using Py2exe 
(http://code.google.com/p/gmapcatcher/) it is a lot simpler than pyChess, I 
thought 
that I could give you guys a hand making a windows installer, it seems that 
this 
project has a LOT more dependencies than GMapCatcher...

 To start I set up Python 2.5 in a fresh Win XP and installed the requirements listed 
in setup_win32.py, it was missing "gtksourceview" I download it from here:
 http://ftp.gnome.org/pub/gnome/binaries/win32/ 
But no luck! 

Has anyone been able to compile this lately?

Original comment by heldersepu on 17 Jul 2009 at 5:23

Hi Heldersepu,

It would be great to have someone give PyChess for Windows another go. It's 
been a
while since somebody worked on that (leogregianin did).

What kind of problems does gtksourceview give you? Perhaps the setup_win32.py 
depends
on gtksourceview1 rather than 2. PyChess supports both though.

If the sourceview is a great trouble, we could make it optional. It isn't used 
very
heavily in the app.

You can also try to write on the mailinglist if there are other things you need 
to
know and discuss (there surely will be)

Cheers, Thomas

Hallo Thomas

 Attached you can find some of the problems with gtksourceview. It seems that
setup_win32.py depends on gtksourceview1 but for debugging purposes I'm trying 
to run
pychess directly.

 I will try removing all the "sourceview" dependencies see if compiles in that way...

I'm glad I can help
Helder

I commented all the "sourceview" dependencies, but I'm still getting errors...
ImportError: No module named rsvg

this might be a solution:
http://cairographics.org/cairo_rsvg_and_python_in_windows/

Original comment by heldersepu on 19 Aug 2009 at 1:43

[GoogleCodeExporter]

Rsvg is used in the Throbber (which appears at discovering) and in the pydock 
(which
appears when you move around panels).
We use rsvg like this:

def __loadSvg (self, path, width, height):
    svg = rsvg.Handle(path)
    surface = cairo.ImageSurface(cairo.FORMAT_ARGB32, width, height)
    context = cairo.Context(surface)
    context.set_operator(cairo.OPERATOR_SOURCE)
    if svg.props.width != width or svg.props.height != height:
        context.scale(width/float(svg.props.width),
                      height/float(svg.props.height))
    svg.render_cairo(context)
    return surface

Your wrapper seams to handle all functions used in this case, so I say you 
should try
copying it in.
At first you will need to copy it into lib/pychess/widgets/Throbber.py as well 
as
lib/pychess/widgets/pydock/OverlayWindow.py. If it works well, we can factor it 
into
some svg module.

Original comment by lobais on 19 Aug 2009 at 6:11

After copying the wrapper to both of the files that error is gone. 
but now I get new error:
gobject.GError: Icon 'weather-clear' not present in theme

I try commenting the "erroneous" lines but it seems the icons are used 
everywhere!
Attached is the full output of the error

In the error there is something about theme not found & You can get a copy 
from:

I run into msgfmp.py error with Python 2.6.6 too. Not tested with 2.7 yet.

This is interesting:

Python docs doesn't mention %T, but I got no error running tests on my XP.

Our main problem with win32 port described in mailing list:

I see.
I guess we could switch all the code back to using idle_add, but we
did switch away from it, because it gave problems. There is a chance
these problems in gtk are fixed, but who knows.
Another possibility could be to make them interchangeable some way.
Anyway I think it would require some overall rewrite of the way we use
threading. Then again, that is one of our high priorities anyway.

You said: 
"Python docs doesn't mention %T, but I got no error running tests on my XP"
It depends from Python version: for 2.6 it returns '', for 2.7 it raises the

I have found the reason why setup.py failed on  line 103:

It is because the Swedish translation does not have pychess.mo file in folder 
lang/sv/LC_MESSAGES/pychess/

I just removed the folder lang/sv/ completely and rerun setup.py install 
without problems.

Most of book.py is outdated. It is code used to generate the opening book, 
which currently isn't accessible to the user. Additionally Justin Blanchard is 
working on making it all obsolete.

Bottom line: Anything that isn't getOpenings or used by it, you can safely 
remove.

Follow-up  to my comment 18: I finally got Welcome-Pychess main window!
Instead first 3 steps described in comment #18 I used pygtk-all-in-one 
installer: 
http://ftp.gnome.org/pub/GNOME/binaries/win32/pygtk/2.22/pygtk-all-in-one-2.22.6
.win32-py2.6.msi (also there is a version for Python 2.7)
It is important to read first 
http://ftp.gnome.org/pub/GNOME/binaries/win32/pygtk/2.22/pygtk-all-in-one.README

Also fixes for strftime("%T") should be applied in LogDialog.py and Log.py 
files and \sv\LC_MESSAGES\pychess.po  should be fixed.

From Welcome-Pychess there are 2 options:
Option 1: Start Game
  Opponent: human being (drop down has no other options - why?)
In file ionest.py, line #80, I found that the following list is empty
      anaengines = list(discoverer.getAnalyzers())
and on line 83 it fails: Index Error - list index out of range
   if engine is None: engine = anaengines[0]

I dig into engineNest.py to understand how to fix it, but I need help from 
somebody here. Please explain me how to configure local chess engine to be 
recognized by engineNest!

Option 2: Connect to FICS
 I tried connect to FICS as guest: I got 2  additional windows
one named "Connect to Internet Chess" with nice Earth picture and after few sec 
the 2nd window appeared "Internet Chess: FICS" which is totally white inside. 
Both windows are having line "Not Responding" in the title. So I have to kill 
both.

mlubin: Congratulations on getting it up running!

On your question: PyChess expects there to always be at least one engine, 
namely the PyChess chess engine. It sounds to me like it has failed being 
initialized by engineNest. Have you checked if you can run it stand alone? (see 
the INSTALL file).

In general the engines.xml file is used to configure local engines. The script 
uses the system path a lot, I don't know if that might introduce troubles under 
windows.

Fixed the strftime() param and sv garbage bugs. Thx!

I think you arrived to the main problem here.
PyChess failed to discover engines (we have at least 1, pychess own engine).
The reason is here:
http://faq.pygtk.org/index.py?req=show&file=faq20.006.htp
As Thomas said we tried method 1. before, but had problems. Now we use method 
2., but this failed in win32.

The default PyChess.py engine is not picked up because in the engineNest.py the 
method
__findRundata the variable altpath always become  None:

        if engine.find('vm') is not None:
            altpath = engine.find('vm').find('path')  # this returns None !

I do not understand what .find('path') stands for in line abobe.

--------------------------------------------------------

From http://docs.python.org/library/signal.html I see that SIGCONT is not valid 
argument on Windows:
On Windows, signal() can only be called with SIGABRT, SIGFPE, SIGILL, SIGINT, 
SIGSEGV, or SIGTERM. 

Any idea how to fix it?

SIGPAUSE/SIGCONT are used for pausing and resuming a process. I did a bit of 
searching, but there doesn't seam to be an api way in Windows to do this.

You can try to search as well. There were some ideas around.

Alternatively I think the engine api's will still work, even if the processes 
aren't actually paused. Maybe some bad engines will have problems, and we'll 
probably have a large cpu usage when a game is paused, but you could give it a 
try and comment the lines out.

I commented out the calls signal.SIGCONT but it does not help :( 
Here is the dump with some my print statements:
