SQLObject 0.8.0b1
Hello! I'm pleased to announce the 0.8.0b1 release of SQLObject. This is the first beta of the new branch. Taking into account that it is a result of rather large job the beta period will be prolonged. Meanwhile the stable 0.7 branch will be maintained, and there will be at least 0.7.3 release. What is SQLObject = SQLObject is an object-relational mapper. Your database tables are described as classes, and rows are instances of those classes. SQLObject is meant to be easy to use and quick to get started with. SQLObject supports a number of backends: MySQL, PostgreSQL, SQLite, and Firebird. It also has newly added support for Sybase, MSSQL and MaxDB (also known as SAPDB). Where is SQLObject == Site: http://sqlobject.org Development: http://sqlobject.org/devel/ Mailing list: https://lists.sourceforge.net/mailman/listinfo/sqlobject-discuss Archives: http://news.gmane.org/gmane.comp.python.sqlobject Download: http://cheeseshop.python.org/pypi/SQLObject/0.8.0b1 News and changes: http://sqlobject.org/devel/News.html What's New == Features Interface * It is now possible to create tables that reference each other. Constraints (in the DBMSes that support constraints) are added after the tables have been created. * Added ``createSQL`` as an option for sqlmeta. Here you can add related SQL you want executed by sqlobject-admin create after table creation. createSQL expects a string, list, or dictionary. If using a dictionary the key should be a dbName value (ex. 'postgres') and the value should be a string or list. Examples in sqlobject/tests/test_sqlobject_admin.py or at http://sqlobject.org/sqlobject-admin.html#the-create-command * Added method ``sqlhub.doInTransaction(callable, *args, **kwargs)``, to be used like:: sqlhub.doInTransaction(process_request, os.environ) This will run ``process_request(os.environ)``. The return value will be preserved. * Added method ``.getOne([default])`` to ``SelectResults`` (these are the objects returned by ``.select()`` and ``.selectBy()``). This returns a single object, when the query is expected to return only one object. The single argument is the value to return when zero results are found (more than one result is always an error). If no default is given, it is an error if no such object exists. * Added a WSGI middleware (in ``sqlobject.wsgi_middleware``) for configuring the database for the request. Also handles transactions. Available as ``egg:SQLObject`` in Paste Deploy configuration files. * New joins! ManyToMany and OneToMany; not fully documented yet, but still more sensible and smarter. * SELECT FOR UPDATE * New module dberrors.py - a hierarchy of exceptions. Translation of DB API module's exceptions to the new hierarchy is performed for SQLite and MySQL. * SQLiteConnection got a new keyword factory - a name or a reference to a factory function that returns a connection class; useful for implementing functions or aggregates. See test_select.py and test_sqlite_factory.py for examples. * SQLObject now disallows columns with names that collide with existing variables and methods, such as _init, expire, set and so on. Small Features -- * Configurable client character set (encoding) for MySQL. * Added a close option to .commit(), so you can close the transaction as you commit it. * DecimalValidator. * Added .expireAll() methods to sqlmeta and connection objects, to expire all instances in those cases. * String IDs. * FOREIGN KEY for MySQL. * Support for sqlite3 (a builtin module in Python 2.5). * SelectResults cannot be queried for truth value; in any case it was meaningless - the result was always True; now __nonzero__() raises NotImplementedError in case one tries bool(MyTable.select()) or if MyTable.select():... Bug Fixes - * Fixed problem with sqlite and threads; connections are no longer shared between threads for sqlite (except for :memory:). * The reference loop between SQLObject and SQLObjectState eliminated using weak references.

Roundup Issue Tracker release 1.3.2
I'm proud to release version 1.3.2 of Roundup. Fixed in 1.3.2: - relax rules for required fields in form_parser.py (sf bug 1599740) - documentation cleanup from Luke Ross (sf patch 1594860) - updated Spanish translation from Ramiro Morales (sf patch 1594718) - handle 8-bit untranslateable messages in tracker templates - handling of required for boolean False and numeric 0 (sf bug 1608200) - removed bogus args attr of ConfigurationError (sf bug 1608056) - implemented start_response in roundup.cgi (sf bug 1604304) - clarified windows service documentation (sf patch 1597713) - HTMLClass fixed to work with new item permissions check (sf bug 1602983) - support POP over SSL (sf patch 1597703) - clean up input field generation and quoting of values (sf bug 1615616) - allow use of roundup-server pidfile without forking (sf bug 1614753) - allow translation of status/priority menu options (sf bug 1613976) New Features in 1.3.0: - WSGI support via roundup.cgi.wsgi_handler If you're upgrading from an older version of Roundup you *must* follow the Software Upgrade guidelines given in the maintenance documentation. Roundup requires python 2.3 or later for correct operation. To give Roundup a try, just download (see below), unpack and run:: roundup-demo Release info and download page: http://cheeseshop.python.org/pypi/roundup Source and documentation is available at the website: http://roundup.sourceforge.net/ Mailing lists - the place to ask questions: http://sourceforge.net/mail/?group_id=31577 About Roundup = Roundup is a simple-to-use and -install issue-tracking system with command-line, web and e-mail interfaces. It is based on the winning design from Ka-Ping Yee in the Software Carpentry Track design competition. Note: Ping is not responsible for this project. The contact for this project is [EMAIL PROTECTED] Roundup manages a number of issues (with flexible properties such as description, priority, and so on) and provides the ability to: (a) submit new issues, (b) find and edit existing issues, and (c) discuss issues with other participants. The system will facilitate communication among the participants by managing discussions and notifying interested parties when issues are edited. One of the major design goals for Roundup that it be simple to get going. Roundup is therefore usable out of the box with any python 2.3+ installation. It doesn't even need to be installed to be operational, though a disutils-based install script is provided. It comes with two issue tracker templates (a classic bug/feature tracker and a minimal skeleton) and five database back-ends (anydbm, sqlite, metakit, mysql and postgresql). -- http://mail.python.org/mailman/listinfo/python-announce-list Support the Python Software Foundation: http://www.python.org/psf/donations.html

Re: merits of Lisp vs Python
This is not a response to any particular post, but rather to the general argument that macros are not as useful as we Lispers claim. Here is a fairly complete GUI RSS reader in 90 lines of Lisp (the GUI code itself is 90 lines, but it makes use of some RSS reading/writing code I had laying around and two public CL libraries: s-xml and trivial-http). The code employs a handy macro called DEFINE-INTERFACE that LispWorks provides with their CAPI toolkit. I hope this will be useful as an illustration of what macros (and Lisp in general) can do, and as an example of what a moderately practical CL application looks like. The application presents a list of feeds and allows the user to add new feeds or to delete existing feeds. The feeds are presented as a tree, with each channel acting as a parent to several items. The user can refresh all of the feeds with the Refresh All button. Double-clicking on any item will display its description field (as in the screenshot). Each channel shows the number of unread articles and the articles are arranged so that the unseen articles appear before the articles that have already been read. Important things to note: 1) the DEFINE-INTERFACE syntax closely resembles the syntax of the standard DEFCLASS macro, so newcomers have a basic idea of what DEFINE-INTERFACE is going to do 2) the expansion ( http://galoot.org/~bill/code/rss-reader/expanded.lisp ) of just the DEFINE-INTERFACE is quite involved, a testament to the amount of work the macro saves 3) much of the GUI can be specified declaratively because of the DEFINE-INTERFACE syntactic abstraction, and this declarativeness makes it very easy for maintainers to understand what's going on 4) even without knowing the implementation of DEFINE-INTERFACE and even without prior experience with it, one can make good guesses about what it does 5) the GUI code is stunningly concise Here is the GUI code alone: http://galoot.org/~bill/code/rss-reader/rss-gui.lisp Here is a screenshot of the application in development: http://galoot.org/~bill/code/rss-reader/development.png and two screenshots of the application in use http://galoot.org/~bill/code/rss-reader/in%20action.png http://galoot.org/~bill/code/rss-reader/in%20action%202.png Here are the support files: http://galoot.org/~bill/code/rss-reader/ Here is an OS X universal binary (run at your own risk; I've only done very basic testing): http://galoot.org/~bill/code/rss-reader/BarebonesRSS.app.tar.gz Enjoy. -- http://mail.python.org/mailman/listinfo/python-list

One side effect of this being third party code is that hosting services may not have it available, even when they have both Python and MySQL up.

use the tokenizer and a simple parser pattern:

use the compiler module and analyze the parse tree:

Neither, nor. In both cases, the operating system is asked, and gives
this answer. However, in the Windows API, there is no exists function
(nor is there on Unix); instead, exists is implemented by calling
several underlying functions. The precise set of functions used did
change between 2.4 and 2.5.
It is quite difficult to investigate the precise nature of the change
that leads to this change in observable behavior. If you think this is
a bug, it would be best if you could also investigate a patch.

That was a mistake, I'll add it back in 2.5.1.

Now it's obvious that when it comes to real-life-size programs, this is a *very* important detail !-) I don't buy this. One of my favorite quotes about specifications (http://www.sgi.com/tech/stl/drdobbs-interview.html): Let's take an example. Consider an abstract data type stack. It's not enough to have Push and Pop connected with the axiom wherein you push something onto the stack and after you pop the stack you get the same thing back. It is of paramount importance that pushing the stack is a constant time operation regardless of the size of the stack. If I implement the stack so that every time I push it becomes slower and slower, no one will want to use this stack. We need to separate the implementation from the interface but not at the cost of totally ignoring complexity. Complexity has to be and is a part of the unwritten contract between the module and its user. The reason for introducing the notion of abstract data types was to allow interchangeable software modules. You cannot have interchangeable modules unless these modules share similar complexity behavior. If I replace one module with another module with the same functional behavior but with different complexity tradeoffs, the user of this code will be unpleasantly surprised. I could tell him anything I like about data abstraction, and he still would not want to use the code. Complexity assertions have to be part of the interface. -- http://mail.python.org/mailman/listinfo/python-list

Off the top of my head, something like re.sub(', *', ', ', 'a,
b,c,d,e, f'), meets your requirements (it also ensures the number of
spaces after the comma is one). However, you may need to refine the
rules depending on what you really want to achieve. For instance, what
happens with: a comma appearing before any text, consecutive commas (ie
,,,), or commas within quotes?

When you are trying things out in the Python shell IDLE, _ is a
shorthand way to use the last value printed by IDLE.
Thus when
s.replace(', ',',')
prints out
'hello,goodbye,boo'
_ refers to that value so the replace operation
_.replace(',',', ')
manipulates that value.

SQLObject 0.8.0b1
Hello! I'm pleased to announce the 0.8.0b1 release of SQLObject. This is the first beta of the new branch. Taking into account that it is a result of rather large job the beta period will be prolonged. Meanwhile the stable 0.7 branch will be maintained, and there will be at least 0.7.3 release. What is SQLObject = SQLObject is an object-relational mapper. Your database tables are described as classes, and rows are instances of those classes. SQLObject is meant to be easy to use and quick to get started with. SQLObject supports a number of backends: MySQL, PostgreSQL, SQLite, and Firebird. It also has newly added support for Sybase, MSSQL and MaxDB (also known as SAPDB). Where is SQLObject == Site: http://sqlobject.org Development: http://sqlobject.org/devel/ Mailing list: https://lists.sourceforge.net/mailman/listinfo/sqlobject-discuss Archives: http://news.gmane.org/gmane.comp.python.sqlobject Download: http://cheeseshop.python.org/pypi/SQLObject/0.8.0b1 News and changes: http://sqlobject.org/devel/News.html What's New == Features Interface * It is now possible to create tables that reference each other. Constraints (in the DBMSes that support constraints) are added after the tables have been created. * Added ``createSQL`` as an option for sqlmeta. Here you can add related SQL you want executed by sqlobject-admin create after table creation. createSQL expects a string, list, or dictionary. If using a dictionary the key should be a dbName value (ex. 'postgres') and the value should be a string or list. Examples in sqlobject/tests/test_sqlobject_admin.py or at http://sqlobject.org/sqlobject-admin.html#the-create-command * Added method ``sqlhub.doInTransaction(callable, *args, **kwargs)``, to be used like:: sqlhub.doInTransaction(process_request, os.environ) This will run ``process_request(os.environ)``. The return value will be preserved. * Added method ``.getOne([default])`` to ``SelectResults`` (these are the objects returned by ``.select()`` and ``.selectBy()``). This returns a single object, when the query is expected to return only one object. The single argument is the value to return when zero results are found (more than one result is always an error). If no default is given, it is an error if no such object exists. * Added a WSGI middleware (in ``sqlobject.wsgi_middleware``) for configuring the database for the request. Also handles transactions. Available as ``egg:SQLObject`` in Paste Deploy configuration files. * New joins! ManyToMany and OneToMany; not fully documented yet, but still more sensible and smarter. * SELECT FOR UPDATE * New module dberrors.py - a hierarchy of exceptions. Translation of DB API module's exceptions to the new hierarchy is performed for SQLite and MySQL. * SQLiteConnection got a new keyword factory - a name or a reference to a factory function that returns a connection class; useful for implementing functions or aggregates. See test_select.py and test_sqlite_factory.py for examples. * SQLObject now disallows columns with names that collide with existing variables and methods, such as _init, expire, set and so on. Small Features -- * Configurable client character set (encoding) for MySQL. * Added a close option to .commit(), so you can close the transaction as you commit it. * DecimalValidator. * Added .expireAll() methods to sqlmeta and connection objects, to expire all instances in those cases. * String IDs. * FOREIGN KEY for MySQL. * Support for sqlite3 (a builtin module in Python 2.5). * SelectResults cannot be queried for truth value; in any case it was meaningless - the result was always True; now __nonzero__() raises NotImplementedError in case one tries bool(MyTable.select()) or if MyTable.select():... Bug Fixes - * Fixed problem with sqlite and threads; connections are no longer shared between threads for sqlite (except for :memory:). * The reference loop between SQLObject and SQLObjectState eliminated using weak references.

Aside from any other problems, the file you are
trying to write to is (opened)?? in the w mode.
Every time a file is opened in the 'w' mode,
everything in the file is deleted.
If you open a file in the 'a' mode, then
everything in the file is left untouched and the
new data is appended to the end of the file.
Your while loop is deleting everything in the file
on each loop with the 'w' mode.

And if you can't answer, then it may be time to learn Python... FWIW, the first version raises an exception (unless of course the name 'index' is already bound in the enclosing scope). And the second won't probably work as expected with CherryPy. -- http://mail.python.org/mailman/listinfo/python-list

pyExcelerator question
I'd like to word wrap some cells, but not others, in an Excel spreadsheet, using pyExcelerator and Excel 2003, SP1, under XP. The code below creates the spreadsheet, but both cells are word-wrapped. As far as I can tell, the second call to XFStyle() overwrites a GLOBAL wrap setting, and affects even cells written before the call to XFStyle. Can anyone shed any light? Thanks, Gerry from pyExcelerator import * w = Workbook() ws = w.add_sheet(alpha) style = XFStyle() style.alignment.wrap= Alignment.NOT_WRAP_AT_RIGHT ws.write(1,1,Not wrapped + - * 50, style) style2 = XFStyle() style2.alignment.wrap= Alignment.WRAP_AT_RIGHT ws.write(2,1,Wrapped + - * 50, style2) w.save(test.xls) -- http://mail.python.org/mailman/listinfo/python-list
Re: When Closure get external variable's value?
Huayang Xia kirjoitti: It will print 15. The closure gets the value at run time. Could we treat closure as part of the external function and it shares the local variable with its holder function? I don't quite get what you are trying to tell us but if you think that in your example code: def testClosure(maxIndex) : def closureTest(): return maxIndex maxIndex += 5 return closureTest() print testClosure(10) you are returning a callable function you are all wrong. This can be easily seen by: type(testClosure(10)) 15 type 'int' The mistake is that you shouldn't return closureTest() but closureTest instead. The correct way would be: def testClosure2(maxIndex): def closureTest(): return maxIndex maxIndex += 5 return closureTest f2 = testClosure2(10) function closureTest at 0x00D82530 type(f2) type 'function' print f2() 15 Cheers, Jussi -- http://mail.python.org/mailman/listinfo/python-list
