[SQLObject] Installation trouble...

[Frank B. <fb...@fo...>]

Hallo,

I'm having problems installing SQLObject on a webserver running
SusE-Linux system. I normally use Debian, so I don't know what exactly
seems to go wrong here.

Using SO-0.3.0 the error I get is this:

# python2.2 setup.py install
running install
Traceback (most recent call last):
  File "setup.py", line 32, in ?
    download_url="http://prdownloads.sourceforge.net/sqlobject/SQLObject-0.3.tar.gz?download")

  File "/usr/lib/python2.2/distutils/dist.py", line 893, in

_init_posix
    raise DistutilsPlatformError(my_msg)
distutils.errors.DistutilsPlatformError: invalid Python installation:
unable to open /usr/lib/python2.2/config/Makefile (No such file or
directory)

python package is python-2.2-166 with this version:

Python 2.2 (#1, May 14 2002, 18:23:13) 
[GCC 2.95.3 20010315 (SuSE)] on linux2

Do I miss to install a package?

ciao

Not sure whether this is the problem, but if setup.py attempts to
download the URL given below, it will come to a "dispatch" page where
you have to chose a mirror, not to the actual software.  

The URL for the SWITCH mirror in Zurich (this should be close to
you?) is
http://prdownloads.sourceforge.net/sqlobject/SQLObject-0.3.tar.gz?use_mirror=switch

that replaces "?download" in the URL listed below with
"?use_mirror=switch"...  Not sure where to change this, but likely you
can edit setup.py...???

hope this works

More troubles [was Re: [SQLObject] Installation trouble...]

I still don't know, what's wrong with the install script, but after I
installed SQLObject by hand, I now have a more serious problem.
Runnings the test script, I posted here earlier (see post regarding
_defaultOrder), I get this error:

$ python fragen.py
Traceback (most recent call last):
  File "fragen.py", line 15, in ?
    class Answer(SQLObject):
  File "/usr/lib/python2.2/site-packages/SQLObject/SQLObject.py", line 124, in __new__
    mod = sys.modules[dict['__module__']]
KeyError: __module__

What does that mean and how to fix? Python is 2.2-final.

ciao

That's weird.  It's like it isn't doing the metaclass thing right.  As
long as you don't use __connection__ that line shouldn't be executed,
for a quick fix (or test)... I wonder if 2.2 has problems (I've been
doing my testing on 2.2.2).

I do, too, but this webserver currently has only 2.2.0 installed.
I'll see, if we can update this without breaking other things. I'm the
only one using python there, the webmaster is a perl guy...

Changing connection to a class variable (_connection = ...) leads me
past this error, but another one comes along:

$ python fragen.py
[...]
Me OR You OR freeForm OR You OR freeForm
-- Ah, no, I guess, "Me" is not a good answer...
Traceback (most recent call last):
  File "fragen.py", line 92, in ?
    a1.destroy()
  File "/usr/lib/python2.2/site-packages/SQLObject/SQLObject.py", line 831, in destroy
    self._connection.cache.purge(self.id)
AttributeError: 'CacheSet' object has no attribute 'purge'

So, I cannot destroy. :(

I guess, the requirements of SQLObject should be raised up 2 minor
numbers...

That's a bug bug, not a version bug.  It's fixed in CVS.

I remember now another failure with my 2.2.0 installation: I had to
add "True,False=..." to Cache.py and DBConnection.py, because
otherwise the bools aren't defined.

Thanks a lot Ian, now with current CVS everything (that I use) seems
to be working fine on python 2.2.0 except the installation. This might
be a broken Suse-rpm, but "cp -r build/lib/SQLObject
/usr/lib/python2.2/site-packages" was all that's needed.

I'm really impressed with the ease of use that SQLObject gives.  It
saves a h*ll of a lot of typing and JustWorks(tm) for my project.
This is a survey application with Webware, where website users get
asked how they like the website. So far only the "add questions and
answers" editing interface is done, but it just took me a couple of
hours to hack this together thanks to SQLObject. I'm sure, the real
survey will be done just as fast.

In this project, performance will be not that important, because we
only have a handful of data, but I wonder how good the performance
with really big databaseses would be? Doesn't SO issue rather plenty
of selects so that performance might drop if lots of data is involved?

Also what would be a preferred way of pooling database connections for
SO in Webware? Does Webware's datapool make sense in the context of
SQLObject? I fear, that every SQLObject I use creates and drops its
own database connection, which would be bad for performance.
