Jason Chu wrote: RAD means Rapid Application Development. How does gzip on vs. gzip off affect the speed of application development?

Gregor Horvath wrote: Isn't this increasing the server load dramatically? Any experiences or figures on this? Yeah, on Apache + PHP *enabling* gzip *increases* responsiveness dramatically. This is extremely noticeable when using phpMyAdmin over a LAN. The vast majority of web applications are I/O bound on the network, not processor bound. Decreasing your remote I/O requirements is a very good thing. On Apache, gzip is performed by the C library zlib, which is extremely fast and has almost zero effect on performance. I believe Python (and CP) utilise zlib also, so is suspect the performance impact will be immeasurable, especially if you consider that most of the rest of the HTTP request is handled by Python code. -Rob --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups TurboGears group.

You'll find your select result only contains 'öö'. This is because MySQL varchar(4) means 4 *bytes*, not characters (and ö is two bytes). It's not multibyte character aware. This can cause lots of exceptions in Python when multibyte characters are truncated at the size limit of a column.

Comments below. Ilias Lazaridis wrote: TurboGears is essentially a toy as long as is cannot rely on a industry-standard-compliant (at least a subset) persistency-layer. You mean like PHP is a toy? PHP only developed a persistency layer beyond thin wrappers around C DB libraries quite recently, yet it seems to be doing alright. PEAR::DB is nothing more than a fancy SQL injection barrier. I think you're missing the point here. I'd say most of the time TG has to work in an existing environment. That probably means MySQL, or Postgres. It's pretty much certain that if TG's model layer is going to abstract away anything, it'll be abstracting away an RDBMS. SO does a pretty good job of it to be honest. If it weren't for the profound performance problems and stagnant development I'd say SO is pretty much as good as it can get. What I really think will be the clincher is SA with an SO API. TG is aimed at making developers' lives easier. Developers know RDBMS. That's how they think. TG's aim should be to allow developers to use an RDBMS exactly how they always did without the sheer tedium of SQL.

Chris,
I believe ActiveMapper alone won't do this, but you can leverage the
rest of SQLAlchemy to do it.
Below is an example of how I've managed to solve the same problem in my
current project.
# create a many to many join between TestObject and TestObject
related_items_table = Table('related_items',
metadata,
Column('id', Integer, ForeignKey(test_object.id)),
Column('related_id', Integer, ForeignKey('test_object.id')))
# Our class definition
class TestObject(ActiveMapper):
## class mapping sets up the DB-Object map
class mapping:
__table__ = test_object
## id stores the unique primary key for this product
id = column(Integer, primary_key=True)
## name gives this product a name
name = column(Unicode(255))
## description gives this product a description
description = column(Unicode(512))
# Then add a relation to TestObject's mapper instance
TestObject.mapper.add_property('related', relation(TestObject,
secondary=related_items_table, uselist=True,
primaryjoin=TestObject.c.id==related_items_table.c.id,
secondaryjoin=TestObject.c.id==related_items_table.c.related_id,
foreignkey=TestObject.c.id))
This will create a relation called TestObject.related which will
contain a list of TestObject instances, which is what I think you are
after.
I hope this helps you solve your issue.
Regards,
Mark.

If Jonathan LaCour (sp?) has no clues I'll set up my own many_to_many and see if it makes a difference. One thought I had is that I'm using MySQL 5, and although SA seems to identify its relational columns with a foreign_key attribute (little too automagic for my liking), MySQL doesn't preserve relations without manual intervention.

[TurboGears] Why I'm knocking TG on the head for a bit
Hey guys I've decided to knock TG on the head for a while and pick up the pace on PHP a bit, driving more into PHP5 with some of my Python lessons. I don't have a problem with Python by the way, just not for web development. Anyway I thought you might be interested in why I'm doing this, so here are some points: CherryPy * It's slow and doesn't allow me the fine-grained control I need for my web projects. * No obvious easy way to do URL rewriting. And no controller.default() doesn't count. * I think the sluggishness is mostly because it's written in Python. Also I can't find a good way to let it handle multiple requests at a time. I wrote an AJAX in-house tool recently. It aggregates data from a website using BeautifulSoup. There's an option to aggregate lots of data at the same time, which it achieves by doing lots of XMLHTTP requests. CherryPy doesn't seem happy with doing more than 2 processes at a time, even with thread_pool increased. There could also be a locking issue. I'm pretty sure this isn't related to FF's max connections/server features - I'm aware of those. I know a similar PHP tool works fine. SQLObject = * I really like SO. Its inteface is great, I wish I could do joins in such an easy manner with PHP. However it is just so slow and flaky I can't handle it any more. Selecting a list of IDs then selecting each row by ID in turn is just unacceptable. REALLY unacceptable. Even my project manager has noticed a website is slow because of this. * I can't stand how SO will bomb out on UnicodeErrors causing a DOS on that page. * I also can't stand how if you remove a row from the database that has a reference somewhere, SO will raise SQLObjectNotFound whenever it goes near that data. My PHP apps don't suffer from this because I write the complete three-table inner join in SQL, which will ignore missing references (and is a boatload faster). It makes the DB a little messy sometimes, but that's nothing compared to DOSing the page with a 500 error. Updating my CRUD methods every time I associate a new object is *not* fun web development. I know the last point can be solved with using a DB that supports foreign key constrains. We use MySQL, there are no PG servers, that's just the way of it. I could convert my tables to InnoDB - I probably will in future. Kid === * The NoneType is not callable bug gets old real fast Documentation = Mostly my fault for using 0.9a*, but 0.9a* contains the only features which attract me. Nevertheless, no docs is no good, and I need to get stuff done *now* = However I will miss some things about TG. Identity is great, top draw on that one. I'll have to port it to PHP very soon. I also like widgets, very much, although without accurate documentation right now it's difficult for me to save time by using them on anything but the most basic of forms. I'm sure with time this problem will go away as I remember more of the API. I'm pretty sure I'll come back, probaly when First Class is ready. As I understand it, FC will be WSGI (which I think means I can run it under Apache without too much flakiness). Also SA support should be properly finished, tested and documented by then, which means I can ditch SO. I will never use SO until it fixes the way in which it selects data from the database. Sometimes slow is just too slow. Actually I'll probably use TG before then. There are certain classes of sites I think TG would be perfect for, but I'll have to think very hard about the specific requirements of the site before firing up TG again.

Those last logging-related tracebacks happen on every page request
(production), so it served a few files before hanging altogether. I
couldn't stop the server with a KeyboardInterrupt, I had to use pkill
-f prod.cfg
Apparently this is related to too many files being open. lsof tells me I
have 2129 file handles open this morning (after killing the server
though). 303 of which belong to python and a whopping 1176 of which
belong to apache!
Anyway I will monitor python's file handles throughout the day and see
what happens.
Thanks now!

Indeed, I later realised this could have been a good approach, but I couldn't really bothered to implement it all again when I know that preforking was a viable and stable solution Thanks for your advice though, if I get another project to do in this vain I'll try and get away with writing a library for this.

[TurboGears] Re: Comet (aka long lived http connections) Ajax in turbogears
I had big throughput problems with asyncore for non-trivial applications. I was making an RSS aggregator and needed to pull in lots of feeds at the same time to get the job done nearly as fast as necessary. I found the overhead in parsing then storing the responses caused my app to spend too long processing and not enough time reading the buffer. The consequence was that there was lots of data waiting for me on the socket which I couldn't read fast enough, causing the socket to fill up and reject incoming packets. My throughput dropped to 25% of my link bandwidth. I re-implemented this app 4 times, and I concluded that: asyncore: slow throughput asynchat: slow throughput (same problem, hadn't worked it out until I finished this one) threaded: depressing locking issues - I now hate python's threading preforked: fastest in both respects but least flexible. It's the methodolgy I always use these days. My IPC is domain sockets. Chews memory, cains cPickle, can't pass around SQLObjects. I don't know if my experience applies to you, however bear in mind that the most successful implementation of this kind of service has been Apache, which is preforked or sometimes prethreaded. -Rob Arnar Birgisson wrote: I will most likely have a look at this soon. I have an upcoming project that includes a sort of BLF (busy-lamp-field) for an Asterisk PBX which would include phone extension status, employee presence and possibly some IM features. I'd like to test Comet instead of polling for updates. Are you talking about using asyncore (which I don't know yet, will read up on it after this email :o) and this code from medusa instead of Twisted, or as a complement?

Yeah I'm well aware, thanks. I'm also well aware that select id from foo limit 10; select * from foo where id='1'; select * from foo where id='2'; etc will never be fast. I'm all for saving memory. But most of the time I just want to output a page in under 5 seconds. Also this methodology assumes that either your SQL server and webserver share the same memory or the SQL server is otherwise short of memory. In my experience this is rarely the case. Even on shared servers the SQL server is free to have over 80% of the available memory. -Rob Joost Moesker wrote: From the SQLObject documentation: Select results are generators, which are lazily evaluated. So the SQL is only executed when you iterate over the select results, or if you use list() to force the result to be executed. When you iterate over the select results, rows are fetched one at a time. This way you can iterate over large results without keeping the entire result set in memory. You can also do things like .reversed() without fetching and reversing the entire result -- instead, SQLObject can change the SQL that is sent so you get equivalent results. You can also slice select results. This modifies the SQL query, so peeps[:10] will result in LIMIT 10 being added to the end of the SQL query. If the slice cannot be performed in the SQL (e.g., peeps[:-10]), then the select is executed, and the slice is performed on the list of results. This will generally only happen when you use negative indexes. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups TurboGears group.

[TurboGears] Re: SQLAlchemy or SQLObject?
I have to say, I have serious problems with SO and heavy-database projects. The main ones are: 1. Maintaining object references, or rather, removing them if an object is destroyed. You can't do Object.destroySelf(), you need to remove all references to it first. This is because SO crashes badly if it comes across a reference to a non-existant object. Which leads me on to: 2. SO pulls too much stuff from the database But also: 3. If SO comes across some bad Unicode data in a database it crashes badly. It provides no method to catch the exception AND find out where the bad data is. I was recently tasked with scanning a 4gb database which I converted to work with SO to find out which of the millions of records had problems. I think SO has an excellent API, but the programming is too unmaintainable and incomplete to make me want to try doing anything with it in the future. Bring on the SA compat layer! -Rob Max Ischenko wrote: For a short-term project (say, a couple of months) SQLObject is probably a better choice - easier to get started, most things you may need will work. For a longer term project I'd seriously consider SQLAlchemy - quality of developemnt docs yields more benefits than SO' familiarity.

FWIW the only search solution I managed to get flying after trying all of the proposals in this thread was a PyLucene based search servce running on an XML-RPC server (using SimpleXMLRPCServer).

[TurboGears] Re: lighttpd and ws/scgi
I also had lots of problems with flup for SCGI deployment, so we wrote our own asyncore-based WSGI/SCGI server. Hi, Mini thread-jack, but I recently wrote a server with asyncore and found it to be less than good as I couldn't get full network i/o because of the amount of time being spent in my dispatcher.handle methods. How did you get this to work? I ended up porting my code to something similar to Apache's prefork mpm, based on SocketServer, which works beautifully. The only difference is my parent and children talk to each other with sockets and not SHM (My app isn't actually a server - it's feed consumer, but I needed multiprocessing to fully utilise my bandwidth) Cheers -Rob --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups TurboGears group.

But, that's not usable yet, and we haven't really started working on 1.1. There are two big issues when it comes to multiple application mounting that you'll have to deal with on your own right now (unless you want to help out with 1.1, but you'll probably be able to move more quickly if you're just using your own interim solution). You're right, but I would like to help on 1.1 if I finished my paid projects any time soon The two issues are: 1) configuration 2) templating #1 is actually somewhat dealt with by cherrypy.tree.mount (what you were remembering). To use that, you just do cherrypy.tree.mount(/foo/bar, YourAppRoot()) Is there any way to add a config file to this so I can use a different sqlobject.dburi? #2 is that there is basically no way to override the master template for an app. Your only standard TurboGears route for customization is the sitetemplate, which may be enough for you.

[TurboGears] Best way to handle sub-project - creating and mounting
Hey guys I was wondering what the best way of handling sub-projects would be, both creating and mounting. In essence I want to create lots of in-house tools with TG (bcoz it rox), yet keep them as discrete as possible so we could pass them on to friends/partners. I know you can mount a controller in the method described for Catwalk, but I really want each one to be able to use a (possibly) different set of database credentials. I remember someone mentioning an alternative method of mounting - I think it was cherrypy.mount or something similar, but I can't remember enough to get anything out of Google :'( Also would you recommend quickstarting a sub-project (so it could also be used standalone), or just creating a directory tree that is suitable? Could anyone provide some advice please? Cheers -Rob --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups TurboGears group.

Hey there You can use PyPAM from http://www.pangalactic.org/PyPAM/ to authenticate against Shadow. There are debian packages. I dunno if you're going to have much luck though - TG requests the user data by username and compares the password with the supplied value, possibly hashed - with PAM you need to know the hashed password before you hash the supplied password - because you need to know what the salt that was used is.

[TurboGears] SQLObject: Accessing a RelatedJoin as as Select results object + memory things
Hey there I have item in my model which have tens of thousands of RelatedJoin members. In the example: class A(SQLObject): bees = RelatedJoin(B) class B(SQLObject): ayes = RelatedJoin(A) Say len(A.get(1).bees) 10,000, and obj = A.get(1) Accessing obj.bees in any way at all causes SO to immediately select every single B that belongs to A - with 10,000 individual queries!! And worse, afterwards it keeps them all in *memory* !! Anyway this is unacceptable. So.. I was wondering if someone could help me with my two problems: 1. I need to be able to select each obj.bees in turn, process it, and move on. This would be acceptable 2. I want to be able to do bob = B.get(x), work on bob, then remove bob from the memory. Performing del bob doesn't work - if I enable debugging and do bob = B.get(1); del bob; bob = B.get(1) only one query is performed. I think the solution is to get obj.bees as a SelectResults object - that way I can perform slice operations to get the data I need. However I have no idea how to do this - I can't seem to get SO to reference the a_b table, and SO documentation is a bit lacking. If 1) and 2) can't be solved, could anyone tell me how to get a regular MySQLdb cursor from turbogears? I can do it all manually but not with A._connection.query*.

It's the same API for two essentially identical tasks 2. Threading/forking is scary for n00bs - I dunno how TG does it, but I know I would be worried about forking or threading a webserver, because forking it is going to leave two copies in memory, and threading while a DB connection is open brings back scary nightmares from projects past.

[TurboGears] Search options: Are there any, should we be considering them?
Hey guys Let's face it, every application on the web these days need some form of search, and as far as I can see, TG + SO/any ORM is going to make that tricky. So I was wondering, should we be thinking about a portable way of providing search for TG apps? Or at least, I think we should provide an integration method for something which is quite easily obtainable, if not shipped with TG itself. I think we have at least two options: 1. PyLucene (http://pylucene.osafoundation.org/) Pros * Stable, well-maintained project * Core engine used in a billion different things * Lots of packages Cons * Appears to be a Java hack * Stems from a Java project * Did I mention Java? * Looks a bit heavyweight 2. XapWrap (http://divmod.org/projects/xapwrap) Pros * Looks quite simple to use * Very Pythonic * Under active development * Cool name Cons * Somewhat immature at the moment * Not full-featured (eg no stemming - do we care?) * Current documentation appears to consist of a few docstrings Personally I would prefer XapWrap, however I need a search engine right now and for internal reasons I'm going to give PyLucene a spin. I'll report back what I think of it. Anyway that's my $0.02 - I hope we can have a good discussion about this. -Rob --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups TurboGears group.

In the past I've also used Lupy (combining the slowness of a pure-python implementation with the awkwardness of a Java style API. With bonus bugginess!) and MySQL's full-text search (if it doesn't have stemming, I have a hard time considering it real full-text search). Our MySQL 4.1 definitely supports stemming, I was just talking to a client about an hour ago about why her search does return result for quickgrin but does for quickgrinder (and likewise for bags - bag) -Rob --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups TurboGears group.

is the app's root on the web?, in the context of a request you can

Well I've wasted a midday and I can tell you PyLucene is a big no-no. A google for cherrypy pylucene brings too many horror stories to mention. Basically something in PyLucene causes CP to bomb out - on my dev setup, insantiating (sp) PyLucene.IndexSearcher() causes an immediat autoreload. There is no configuration solution. Someone mentioned something about using PythonThread but no details on implementation, I'm looking in to that now (http://www.mail-archive.com/pylucene-dev@osafoundation.org/msg00377.html) It does in fact appear that Lucene won't work in-process with CherryPy at all. You need to either write some sort of service for it, or run it as a subprocess which is just nasty.

If the user on the other side has a 56K modem, it will take them longer to download the page (if they're hitting CherryPy directly). I think it's more interesting to measure the time it takes the server to generate the page, because that's the part that is reasonably optimizable. Yeah you're right, we just need up until the end of KID processing. AFAIK the old time display was quite wrong because Kid is a significant bottleneck when generating a page.

You can do this: from cgi import escape escaped = escape(original_string) ...do your regex to put in strongs and whatnot... XML(the result) profit!

I won't indeed. ;-) Oh, my pet hate about GNOME is that their idea of user friendliness is drastically slashing features and functionality that users are crying out for (and ignoring pleas for re-inclusion).

I prefer maintaining an English template -- even though English is not my primary language -- than working with regular expressions (and I have a Perl (!!!) background... ;-)). I believe that there's some way to declare it like this: #if python23 #def expose_decorator [turbogears.expose()] #end def #def identity_decorator [identity.require(...)] #end def #else if python24 #def expose_decorator @turbogears.expose() #end def #def identity_decorator @identity.require(...) #end def #end if and then use it like: #expose_decorator or #insert expose_decorator Something like this looks much more maintainable to me and it is easy to use... BUT, I don't know the syntax for this template, so... I don't think this scales.. if decorators transformations really are as simple as my regular expression, then using an intermediate syntax for a decorator and then doing the appropriate substitutions would be better. Just as an example, something like: class Something(controller.Root): $[[[expose(template=...)]]] def index(self): ... pass Then when we write the template we can change those to the correct form. ... with a regular expression ;-) -Rob --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups TurboGears group.

[TurboGears] Re: KID got error while process javascript operator
Using comments to wrap something that you want to keep in the document is a bad idea. Sure, it might happen to work with Kid, but I still wouldn't do it or recommend it. That technique has been recommended for JS since day 1. It's the standard way of hiding JS from non-javascript-aware browser. You wrap it in a comment so if your user agent doesn't understand JS, it doesn't go printing it everywhere. Not that you should be putting JS in your body/ though. I'm fine with JS on-page when it only affects that page. Including it in a global JS file increases bandwidth. Including it in its own external file causes connection overhead (in HTTP/1.0) -bob -Rob --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups TurboGears group.
