declaimed the following in comp.lang.python:
.execute() is a cursor method, not a connection method. Some DB API
modules do implement it as a connection method, but that makes it
impossible for several cursors to share the same connection (which is
allowed by some modules).
It struck me that the original wasn't using a cursor just after the
messages posted.
It doesn't look like the OP is using anything even remotely DB-API
compliant:
import cmi
snip
import hermes
conn = hermes.db()
snip
pubID=cgiForm.getvalue('pubID')
pubName=cgiForm.getvalue('pubName','Unknown Publication')
sqlcheck1 = SELECT pub_type FROM medusa.cmi_publication WHERE pub_id =
'+pubID+'
overseas1 = conn.query(sqlcheck1)
pubType = cmi.fetch_rows(overseas1)
hermes is apparently some wrapper that magically can connect to a
well-known database (via the argumentless db()) call. Who knows what
kind of animal the 'conn' object is that comes out of that db() call.
Apparently it's an object with a query() method that returns something
like a cursor that can be passed into cmi.fetch_rows(). At this point I
wonder why the responsibility of fetching rows is in a module separate
from the responsibility of establishing a database connection.
Legacy code, indeed.

Your script is called re, so import re is making the script import

That is indeed a problem. For some as of yet undetermined reason, the

I don't want bits to be reinitialized each time. It must retain the set values for the next time it is called. Python does not have static variables in the sense that C does. You can fake it in various ways, though. If I had to do it, I'd define a callable object instead of a function, along the lines of this: class BitSetter(object): def __init__(self): self.bits = [0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0] def __call__(self, bit_index, bit_value): self.bits[bit_index] = bit_value # do something with self.bits here... print self.bits set_bit = BitSetter() Now you can call set_bit(...) as if it were a function, and it'll behave the way you want.

Re: Setting up InformixDb

I downloaded InformixDb-2.2 and managed to get it built and installed and it works fine with python. My problem is I want to access the same database from a PC remotely. Yes, I already have informix setup and configured on the unix machine to accept connections remotely. And, I can connect to it fine from an ODBC interface to Excel and Access. But, to build the informix module requires the INFORMIXDIR environment variable set to it which I don't believe I can set to a remote machine. So, how can I get this module built without having an informix installed on my PC? On the PC, you'll have to install either the Informix Client SDK (http://www.ibm.com/software/data/informix/tools/csdk/) or Informix Connect (http://www.ibm.com/software/data/informix/tools/connect/). Both are free downloads. If you plan on building InformixDB from source, you'll need CSDK. If you want to simply use a pre-built binary, such as the one I provide at Sourceforge, either CSDK or Informix Connect will do. In either case, INFORMIXDIR on the PC should point to where you installed the Informix client software, and INFORMIXSERVER points to the server instance you're connecting to.

SOMEVAL__exact, etc., where SOMEVAL is some value that it parses from
the keyword.
Now, I want to call this function, specifying the kwargs. The problem
is that I want to dynamically set the kwargs. For example, I don't want
to hard code in the name like such:
function_call(name__exact=Tom)
I want to generate the keyword on the fly. So, I want to do this:
(assume someVar == 'name' for now)
keyword = someVar + __exact
The problem:
I need to know how to get it to use the VALUE of the keyword for the
keyword.
My thoughts:
(1) Maybe I can override the kwargs parameter by doing such:
function_call(kwargs={keyword:Tom})
*loud buzzer* Nope. (as expected)
(2) Maybe I can just pass it in:
function_call(keyword=Tom)
Nope! (as expected, it tries to use 'keyword' as the keyword)
The correct answer is behind door number 3:

Usually I would do something like this by having 1 table with special column to categorize the records as I am doing with each table, but this specific application requires that I do it with 4 tables instead.

If I add it to the tuple of parameters in the second arg before val1 and replace tableName with %s, then the tableName will be quoted in the query, causing an error. What is the best (easiest) way for me to accomplish this? I know it may be a stupid question but I just can't figure it out. As you have discovered, the table name is not allowed to be a parameter. You have to build the query string for the appropriate table, then hand it to execute for filling in the actual parameters: queryString = update +tableName+ set col1=%s, col2=%s,... c.execute(queryString, (val1, val2,...))

errata_package is obviously not just the errata_topic hash value,

While I don't understand the question, it might be pertinent to observe that, among open-source development projects, Python is unusual for the *large* number of forks or alternative imple- mentations it has supported through the years URL: http://phaseit.net/claird/comp.lang.python/python_varieties.html . The question is, can anyone just fork a new one using the python name, as part of the project, without the permission from the foundation ? Say for example, anyone want to implement java needs permission from Sun(or is it javasoft), if I rememeber correctly. Therefore, the only way to make change to java the language is to convince Sun, very similar to the model of Python. But many open source project is not using this model. Most of your question can be answered by reading the license. Section 3 of version 2 of the PSF license states: 3. In the event Licensee prepares a derivative work that is based on or incorporates Python or any part thereof, and wants to make the derivative work available to others as provided herein, then Licensee hereby agrees to include in any such work a brief summary of the changes made to Python. In other words, you can change Python to your liking and distribute the changed version, as long as you tell people how it differs from Python. Since the changed version is different from Python, calling it Python would be a) boneheaded and b) as Steve Holden points out, a trademark violation. Note that section 7 states that This License Agreement does not grant permission to use PSF trademarks or trade name in a trademark sense to endorse or promote products or services of Licensee, or any third party and the Python name is a trademark of the PSF. So, if there is something you don't like about Python, you have two choices: 1) Seek consensus with the Python community and have your changes accepted into the official Python version, or 2) Fork Python into something else with a different name. If the different name contains 'Python', you'll probably have to ask PSF for permission. In any case, as outlined above, you have have to state that the fork is based on Python and summarize how it differs from Python.

When I run the program in a bash shell with the command python ipscan.py, the program runs fine and the results are appended to update.log. When I run this program as a cron job under the root user with the previously mentioned command, the program runs without errors but does not append an entry to the log.

You're not giving us much detail about your script, so we can only guess. My guess is that your python script is either not invoked at all or it dies (raises an exception) before appending to the update.log.

Re: Retain reference to a struct

Hi All,
A C library I'm using has a number of functions that all require a
struct as an argument. The example module shows how to make a new
Python Object from C code and I've seen other posts that recommend this
way of doing it.
In this case though, it would seem easier if I could create the object
in the Python code. This would require storing a pointer to an
instance of the struct until a certain function is called.
I can get the pointer into the python code, but whenever I try to use
it to call another function, the module segfaults. Can anyone suggest
why this is?
static PyObject *
libpyq_PQconnectdb(PyObject *self, PyObject *args)
{
PGconn *conn = PyMem_New(PGconn, sizeof(PGconn *));
conn = (PGconn *)PQconnectdb((const char*)
PyString_AS_STRING(args));
printf(%p, conn);
return PyLong_FromVoidPtr(conn) ;
}
static PyObject *
libpyq_PQfinish(PyObject *self, PyObject *args)
{
printf(%p, args);
return 1;
What exactly do you think you're returning here? The function
declaration says that you're supposed to return a pointer to a PyObject.
'1' is not likely to be a valid pointer to anything.
}
import libpyq#works fine
conn = libpyq.PQconnectdb#conn now a pointer
Are you sure that's the correct example code? As written, that line
doesn't call the PQconnectdb function. It assigns conn to be an
alternate name for the PQconnectdb function.
libpyq.PQfinish(conn)#segfaults
That's probably due to the fact that the python interpreter wants to
look up your return value for printing it, but you're returning a bogus
pointer.
I'm new to C but relatively experienced with Python. I have a sneaky
suspiscion there's a good reason for not doing it this way but I
haven't seen a good explanation of why not yet. If you know one,
please tell me.
The idea of passing around pointers as numbers is very unpythonic. There
is no guarantee that the number that's passed into PQfinish actually
came from a call to PQconnectdb. The user could pass in any integer and
(probably successfully) attempt to crash the system. You should really
wrap the C struct (or the pointer to the C struct) into a Python object
instead.
By the way, it looks like you're trying to write some sort of database
access module. The 'pq' looks suspiciously like it's for PostgreSQL. If
that's the case, can't you just use an existing module for connecting to
PostgreSQL?

You have a lot of cases where findelement is called recursively and then
its return value is discarded instead of being turned into a return
value to the caller. In those cases, execution simply falls off the end
of the function and None is returned implicitly (and silently, since you
don't have a print Returning None at the end of the function).

[ANN] Python API InformixDB-2.0 released
Hi everybody, Thanks to significant code contributions by Daniel Smertnig, I am proud to announce release 2.0 of the Informix implementation of the Python DB-API, a mere 5 weeks after release 1.5. Downloads and info at http://informixdb.sourceforge.net/ This release features the following improvements over InformixDB-1.5: * Full compliance with version 2 of the DB-API specification, including many useful optional features suggested by the specification. * Improved documentation: Command line help and HTML manual. * Improved portability: The module now builds painlessly on Windows, and a binary installer for Python 2.4 is provided. Note that this release requires Python 2.2 or better, and it breaks backwards compatibility with version 1 of the DB-API specification. If either of these are a problem for you, you may still use InformixDB-1.5, but I strongly recommend upgrading as I won't develop InformixDB-1.5 any further.

MySQLdb is installed, no problems. I think that I am having some kind of error with my csv going into the fields and being broken apart correctly. Can someone please help? I attached the code below, it does work with that SQL server also if you want to try and run it. Thanks in advance .. There are two obvious faults in your code: 1) You're using the % operator to plug your parameters directly into the query string. Don't do that. Pass the parametrized query as the first argument to execute(), pass the parameter tuple as the second argument to execute(), and leave it to execute() to plug in the parameters. Once 1) is fixed, you'll run into... 2) The ID column is a NOT NULL column. There is no default value for it, nor is there an AUTO_INCREMENT flag on it. You're not specifying a value for ID in the insert statement. Either this will fail on the first insert (attempting to insert a NULL value into a NOT NULL column), or in case MySQL helpfully defaults the ID to 0, it'll fail on the second row when the primary key constraint is violated by attempting to insert another 0. To fix 2), you'll wither want to make the ID column an AUTO_INCREMENT column or explicitly specify a value for the ID column in the insert statement. (Using AUTO_INCREMENT is easier.) Hope this helps, Carsten. P.S. You need to learn how to describe your problem accurately. Phrases like no problems and it does work juxtaposed with some kind of error do nothing to describe what actually works and what doesn't work. I'm betting python raised an exception when you ran your code. Instead of guessing randomly (and incorrectly) that there is some kind of error in your csv parsing, you could have, for example, included a copy of the exception message. -- http://mail.python.org/mailman/listinfo/python-list
