- may bug fixes.
It contains 537 pages.
Thanks to Alvaro, Bruno, Denes, Felipe, Graham, Jonathan, Hans, Kyle,
Mark, Michele, Richard, Robin, Roman, Scott, Shane, Sharriff, Sriram,
Sterling, Stuart, Thadeus for proofreading this and previous versions
of the book.
It costs one dollar more than 2nd edition, I guess it is because of
the increased number of pages. I actually reduced my cut.
Hopefully it will be available in print soon.
I will take some help in converting to ePub.

I'll be happy to set also form.vars.user.readable = False to hide the field at all, but that's your choice. Feel free to ask more if you're concerned by something or if you didn't understand all.

Re: [web2py] Re: Should we have a feature freeze and stability maintenance period in future?
Hi all, I do develomplent with many different things, different languages architectures and looking for tools for managing software projects is a must for me ;-) I think the problem here is that web2py has started to receive the deserved attention by the user and developer community. Prof. Massimo is doing his best to keep with the growing volume of request. The question is: design of new features is slowed by bugfixing? Well I red from Massimo 2 alerts similar to the following (Massimo feel free to correct me if I am wrong!!): 1. Please remind me of patches to be applied 2. I need to keep track of messages, so no IRC Due to web2py success things will get worse, then I would suggest to start focusing on 2 main points to see if we can find some ideas/solutions. 1) version control I perfectly understand Massimo position: dealing with mercurial (git,bzr) is a pain! Anyhow we must help Massimo delegate some dirty work to others, since we need Massimo to do the important stuff. I think that somehow Massimo's web2py problems resemble those that Linus' Linux faced at the end of '90s. I just remind that Linus to end the thing had written the git system! Please take time to read this chapter: http://hgbook.red-bean.com/read/collaborating-with-other-people.html and this: http://hgbook.red-bean.com/read/collaborating-with-other-people.html#id372519 The model for Linux development IMHO is too much at this time, but some ideas should be taken into consideration. 2) issue tracking We *must* setup a ticket system. Discussion on groups,IRC will eventually lead to a new ticket, but *only* tickets must be taken into account for bugfixing. Code snippets, error log, must be tracked there. ciao, mic 2010/8/23 mart msenecal...@gmail.com: Hi Again, So, spending the day with my 3 girls certainly does provide perspective on requirements and how well attached we can be to them sometimes ;). That in mind, I certainly do understand your personal requirements on keeping what you know and what works for you (I respect old fashion ;) ). We can work with that, while hopefully bringing something efficient, scalable and most certainly flexible, while remaining respectful of what is important to Mr Di Pierro who brought us all here. Although I haven't spent too much time with Mercurial, most concepts don't change, and implementation well... that's all it is really. I had look @ your src repository and I find it is very telling of how you do things and what is important. As I understand, the goal is to meet 2 separate requirements that inevitably impact one another with current structure. The desired outcome: no freeze of the code line while allowing for planned testing iterations to move forward (while enabling Mr Di Pierro to maintain those elements of the current model which are important to him). I think it's entirely doable and please don't hesitate to stop me if I get carried away... I would like to start, if there are no objections, by getting a high level understanding of current practices. So, I'll throw a few questions out there. (I will try t keep the number of questions short – although it may not appear that way). Perhaps, this could be taken to another area to minimize the ruckus? I like the idea of getting a group together and collaborate on developing a proposal. As the more input we have, the better we can serve this type of development model (the concept of contributors) in the web2py dev world in particular. I see that Mr Di Pierro commits all changes to the single branch (default). Here's are a few questions with that: Where do developers check-in or commit their changes while in development? Where does the src going to dev come from and at what frequency does it get synced with the reference code line (if at all) ? Is the reference code line stable (no changes) or is it in constant flux? Since Massimo, is doing the commits, I assume that everybody keeps a sandbox copy of the src? Is there a mechanism in place which makes sure that everyone is working off the same starting point? If not, how are merge conflicts handled presently? Does the code get reviewed before making its way to Massimo who will be committing the changes (or not committing)? As the “release guy”, my first and most important consumer of builds is QA - the testers usually get first dibs on my time ;) - as they are the ones blessing builds and enabling them to move to the next levels. I tend to want to have them in mind when writing automation and making sure they can interface as smoothly as possible to my automation with there own. When going to Test, what get's handed off (src or build)? Is there any regular automated/manual testing? Or is it the case where bigger testing efforts are done later in the release cycle? how are builds identified with those test results? Good release strategies do help, so here are just a few questions on that subject: Have you a
[web2py] filename length bug in sql.py under win32
Hi, I posted some time ago a problem related to uploading a file with a very long filename under window ( it crashes ). I have been able to spot that the issue is in sql.py around line 2799( function store ). So the pb is related to the python interpreter under win32 that doesn't allow the creation of a file descriptor when the path+filename is longer than 255 ( the ntfs filesystem does allow this but it seems to be related to the way python handle it) I don't really know what to do here but may i suggest to change the naming scheme so that generated filename is shorter ( something containing only a uuid and not the encoded part of the filename). Cheers,

anything.

I have a basic update form code that is called via a HREF form another view and form a menu. The problem is the redirect to the referrer is not working. I looked in the forums and have tried to debug. I understand the form is posting back to itself which is why the form is redirected to itself. The forums offer several solutions that depend on a hidden form element embedded in the calling view which are save as request.vars. I am not sure how to make this work with a menu. I hope there is a clean elegant way to accomplish this. Any help would be apprecaited.. @auth.requires_login() def editmeeting(): if not request.args: session.flash = 'Invalid parameter' redirect(URL(r=request, c='default', f='index')) meeting = db(db.meeting.id == request.args(0)).select() if len(meeting): meeting = meeting[0] else: session.flash = 'Invalid meeting' redirect(URL(r=request,c='default',f='index')) form=SQLFORM(db.meeting,meeting, submit_button='Update Meeting') if form.accepts(request.vars, session): redirect(request.env.http_referer) elif form.errors: response.flash = 'Invalid data.' return dict(form=form)

In fact, I am not expert in anything :) I think that a good beginning to create a list of possible features that, in my opinion, it should haveWeb2pyin reference toSEO, would be the Google’s doc Google's Search Engine Optimization. Starter Guide , and it can be found in http: //www.google.com/webmasters/docs/search-engine-optimization-starter-gui... . It is a brief document, of only 22 pages, but very interesting and whose reading I recommend. In addition, it has links to go deeper into some treated topics, as well as to tools for webmaster related toSEO. What I am going to expose is a small summary of the document, as a list, of the elements that a web site must have in order that it could obtain a good positioning. I think that in some of them,web2pymight facilitate the fulfilment of these elements. 1.- Create unique, accurate page titles, Create unique title tags for each page, Make use of the 'description' meta tag, Use unique descriptions for each page, Improve the structure of your URLs. When Google presents us a list of webs as result of a search, he presents first the title of the web, a small text, which can - or not - match with the text of the meta tag description, and a url link to the web. So is very important put the major care in refilling this meta tags. So I think thatWeb2pymust to ask for title and description when created a new application. In order that every page has a title and a different description, depending on his content, maybe doing that the controller returning variables title and description?? URL’s must included words that can be found in a user search. And reflected the web’s structure, if possible, clean and ordered. Also, if a user “cuts” some parts of a url, (www.exemple.com/an/url/very/ large/ and user cuts /large, for example) the reply not would be an stranger message. About url’s, I thinkweb2pydoes a good job. 2.- Make your site easier to navigate Everything related to the user ease of navigation will be appreciated by the search engines. In fact, inSEO, accessibility and usability counts. So it's recommended a sitemap (lower case), that is a html file, generally located in the root, and with a hierarchy links of the pages of the site, maybe with its title and description. This file is aimed to human visitors. Also, it's recommended a Sitemap (upper case), That’s a xml file, aimed to search engines. With this file, the webmaster can inform to search engines about the frequency of changes of the web, or what are the most important pages of our sites. In both files, I think thatweb2pyhas job to do. Another interesting element would be a “breadcrumb”. That’s a row of internal links, located in top or/and bottom of the page as title.site title.page1 title.page2 title.page3. There a lot of snippets of code in Django that implements a breadcrumb. Also, there a project in google code in http://code.google.com/p/django-breadcrumbs/ ;. Whats aboutWeb2py?? And last, a 404 personalized page, that kindly redirects users to the root, or show a list of links of the most visited pages, its very appreciated. 3.- Offer quality content and services , Write better anchor text, “Use heading tags appropriately” “Optimize your use of images” Well, I think with that, any framework has nothing to do. :) 4.- “Make effective use of robots.txt”. Maybe allweb2pyapplication would be, by default, a robots.txt file with, at least, this content: User-agent: “ Disallow: /static/ A robots.txt is a good practice, simple to follow. 5. “Be aware of rel=nofollow for links”. As example of use, the google’s document example: a href=http://www.shadyseo.com/rel=”nofollow”Comment spammer/a Maybe interesting. As point the google doc: “Setting the value of the rel attribute of a link to nofollow will tell Google that certain links on your site shouldn't be followed or pass your page's reputation to the pages linked to. […]If your site has a blog with public commenting turned on, links within those comments could pass your reputation to pages that you may not be comfortable vouching for. Blog comment areas on pages are highly susceptible to comment spam. Nofollowing these user- added links ensures that you're not giving your page's hard-earned reputation to a spammy site.

[web2py] Re: IS_IMAGE() broke?
I was also experiencing this issue, but found that rebuilding the
database only worked until the first valid upload, after which it is
broken again.
In my case, I am using:
Field('photo', 'upload', uploadfield='photo_data',
requires=IS_IMAGE(extensions=('jpeg'))),
Field('photo_data', 'blob', requires=IS_IMAGE(extensions=('jpeg'))),
And was using SQLFORM to display the update form.
When I first added this, it was accepting absolutely everything (pdf,
odt, zip) as an upload. I deleted my database entirely, and had it
rebuilt. I first noticed that it started rejecting non-image uploads.
However, once I had uploaded an image, all subsequent uploads of non-
image types were allowed again. A second database build showed the
exact same behaviour; proper rejection until the first valid upload.
I then made a backup of my web2py folder, and extracted today's
nightly build over my folder. Rebuilding my database one last time, it
shows the exact same behaviour.

[web2py] Model with many to many defined across multiple database instances

# Global table of known servers

update=request.now, writable=False, readable=False),
Field('hostname', 'string', length=64, required=True,
notnull=True, unique=True, label='Hostname:'),
format='%(hostname)s'
)
# Global table showing which servers perform known functions for which
sites.
# The default is a server provides all services.
db.define_table('site_servers',
Field('uuid', 'string', length=64, default=str(uuid.uuid4()),

Field('last_modified', 'datetime', default=request.now,

Field('site_uuid', 'string', length=64),
Field('server_uuid', 'string', length=64),
Field('web_server', 'boolean', default=True),
Field('archiver', 'boolean', default=True)
)
db.site_servers.site_uuid.requires = IS_IN_DB(db, 'sites.uuid', '%

db.site_servers.server_uuid.requires = IS_IN_DB(db, 'servers.uuid', '%
(hostname)s')
sites_and_servers = db((db.sites.uuid==db.site_servers.site_uuid)
(db.servers.uuid==db.site_servers.server_uuid))
The problem is this line that should be used to test for uniqueness of
the site_servers rows so I don't get duplicate entries in the join
table causes the server line of the site_servers insert form to change
from a drop down selecting from existing servers to a text input line.
# Test for uniqueness across site_uuid and server_uuid
db.site_servers.server_uuid.requires = IS_NOT_IN_DB(db
(db.site_servers.site_uuid==request.vars.site_uuid),db.site_servers.server_uuid)
I took thie problem line from several other posts, however they were
not involving uuid and timestamp tables meant for global use across
multiple installations of the database.
I have trimmed some fields from the model to simplify the definition.
Also the example in the DAL chapter third edition of the book under
the heading CSV and Remote Database Synchronization shows the
'modified_on' field setting of default=now which results in undefined
variable now. I believe that should be default=request.now
Thanks for any advice

A much more sophisticated solution Massimo! I completely missed the

Going back to the original question, the point here is that when you
have a 'normalised' table of question/answers, you need to decouple
from SQLFORM (with SQLFORM.factory) and handle the db interactions
more explicitly.

We need to clarify the goal. The goal is not to propose questions to

score be computed? What is the answer is Darwin and he answers
darwin or Charles Darwin?
Anyway, the above code can be simplified in:
db.define_table('q_and_a',
Field('question'),
Field('answer'))
def check(correct_answer,answer):
if correct_answer.lower() in answer.lower(): return 1

[web2py] Re: Model with many to many defined across multiple database instances
To simplify I just used standard id fields, copied the scaffold
(welcome) application with create new application in admin and then
in db.py
changed the db line to match MySQL and created the database
else: # else use a normal
relational database
# db = DAL('sqlite://storage.sqlite') # if not, use SQLite or
other DB
db = DAL('mysql://xxx:y...@localhost/testing') # testing
then added the following to the bottom of the model file db.py
# Global table of known sites
db.define_table('sites',
Field('name', 'string', length=16, required=True, notnull=True,
unique=True, label='Site name'),
Field('long_name', 'string', length=64, unique=True, label='Site
full name'),
format='%(name)s'
)
# Global table of known servers
db.define_table('servers',
Field('hostname', 'string', length=64, required=True,
notnull=True, unique=True, label='Hostname:'),
format='%(hostname)s'
)
# Global table showing which servers perform known functions for which
sites.
# The default is a server provides all services.
db.define_table('site_servers',
Field('site_id', db.sites),
Field('server_id', db.servers),
Field('web_server', 'boolean', default=True),
Field('archiver', 'boolean', default=True)
)
db.site_servers.site_id.requires = IS_IN_DB(db, 'sites.id', '%
(name)s')
db.site_servers.server_id.requires = IS_IN_DB(db, 'servers.id', '%
(hostname)s')
sites_and_servers = db((db.sites.id==db.site_servers.site_id)
(db.servers.id==db.site_servers.server_id))
Commenting out the following lines shows servers as a drop down list
on the insert site_servers form, leaving the line active causes the
servers line to be a text input field.
# Test for uniqueness across site_id and server_id
db.site_servers.server_id.requires = IS_NOT_IN_DB(db
(db.site_servers.site_id==request.vars.site_id),db.site_servers.server_id)

Adding to mytables some strings to see the list of them in example
code.
Clicking on 'show me' give a list of table rows.
Clicking on any of row shows form for string update.
But if you submit changes, they does not reflect in list of items (but
the same time db table row was updated)
Next time submit updates the list of items was made last time.
Question: how to make update of db table before updating list of item
of the same table?

[web2py] Re: How to start server from within a python file ?
It does not hang. It starts the server. The server blocks. If you want
to start the server is a new thread:
import os, sys, thread, time
filepath = r'P:/Web2Py/web2py_src/web2py'
sys.path.append ( filepath )
os.chdir ( filepath ) ## == absolutely necessary to
get the version number !!!
from gluon.main import HttpServer
server = HttpServer ( password='xxx' ) #ip,port,admin_password)
thread.start_new_thread(server.start,(,))
print 'piep'
time.sleep(1)
will print piep but will only live for 1. It is up to you to
handle concurrency.

[web2py] Re: filename length bug in sql.py under win32
This is a complex issue. The length of a filename is limited to 200 chars + extension. There is no way to limit the length of path+filename since the path depends on where web2py is installed and it outside web2py control. Even we were to limit len(filename) to 1 character, this function may still fail if len(path+filename)255. I say this is a major windows bug. Massimo On Aug 23, 5:11 am, Sw1 swel...@gmail.com wrote: Hi, I posted some time ago a problem related to uploading a file with a very long filename under window ( it crashes ). I have been able to spot that the issue is in sql.py around line 2799( function store ). So the pb is related to the python interpreter under win32 that doesn't allow the creation of a file descriptor when the path+filename is longer than 255 ( the ntfs filesystem does allow this but it seems to be related to the way python handle it) I don't really know what to do here but may i suggest to change the naming scheme so that generated filename is shorter ( something containing only a uuid and not the encoded part of the filename).

[web2py] crud.archive issue with unique
Hello, if I have unique field in mytable. How should crud.archive deal with it? I tried setting it after mytable and mytable_archive declaration, but then it doesn't apply it to mytable... db.mytable.name.unique=True ps.: in http://web2py.com/book/default/chapter/07#Record-Versioning and in docstrings there is said, thtat crud.archive creates mytable_history, but it creates mytable_archive ..
[web2py] Re: crud.archive issue with unique
you cannot set the unique attribute after the table definition. Moreover it would be a problem with archive unless you make the archive table manually with fields that corrspond to the table to be archived but with unique=False.

[web2py] Web2py and threads
Hello, I would like to know how Web2py is managing threads. Is it like Java servlets where requests are mapped to servlets while one servlet object can be used by multiple threads at the same time to serve many requests? Are some users here using Jython with Web2py to get around the ugly Pyhton GIL? I would to know about your experience. -- Pierre
[web2py] Re: My editor ...
Is it possible to post a free version of this _as it is_ ? Some of us my find it very useful. Or even, a version without the wysiwyg, if that's the problem.
[web2py] Re: Web2py and threads
In Java a serverlet, as far as I understand, is a class which conforms to some API that allows it to serve one http request. Each instance is executed in its own thread. The Python equivalent of the serverlet API is a WSGI application and web2py is based on WSGI, therefore the parallelization mechanism is equivalent to Java serverlets. In web2py (the same in Django, Pylons, any any WSGI app) each http request is executed in its own thread. Threads are recycled to server non-concurrent requests and reuse database connections (pooling) without need to close and reopen them. The web server can be configured for a min number and a max number of threads. I think the GIL in this context is a false problem. In fact in production you can use Apache and run as many processes as the number of cores that you have. Each process will create as many threads as it needs to server multiple requests. The GIL is a problems only if one process runs multiple threads on multiple cores. It is possible there are some caveats with many cores but I have not really played with apache configurations and benchmarks. I do not think using Jython helps anything. According to these tests: http://blog.dhananjaynene.com/2008/07/performance-comparison-c-java-python-ruby-jython-jruby-groovy/ http://pyevolve.sourceforge.net/wordpress/?p=1189 Jython is 2x-3x slower than cpython. So you may get better scaling with multiple cores but you pay huge perfomance hit. Web2py runs on Jython but there is a known bug in Java regular expressions that Sun marked as won'tfix that can cause runaway problems when parsing complex templates. This is not a web2py specific problem but we have seen effects of the bug in some web2py apps.
