web2py 1.96.1 is OUT

[Massimo Di Pierro]

I could not wait any longer. We had so many changes that we need to
move on.
I do not recall any other release with so many new features. Thanks to
all those who have contributed with patches and testing.

Changelog:

- "from gluon import *" imports in every python module a web2py
environment (A, DIV,..SQLFORM, DAL, Field,...) including
current.request, current.response, current.session, current.T,
current.cache, thanks Jonathan.
- conditional models in
models/<controller>/a.py and models/<controller>/<function>/a.py
- from mymodule import *, looks for mymodule in applications/thisapp/
modules first and then in sys.path. No more need for local_import.
Thanks Pierre.
- usage of generic.* views is - by default - restricted to localhost
for security. This can be changed in a granular way with:
response.generic_patterns=['*']. This is a slight change of behavior
for new app but a major security fix.

- all applications have cas 2.0 provider at http://.../user/cas/login
- all applications can delegate to login to external provider
Auth(...,cas_provider='http://.../other_app/default/user/cas')
- A(...,callback=URL(...),larget='id') does Ajax
- URL(...,user_signature=True), LOAD(...,user_signature=True) can sign
urls and @auth.requires_signature() will check the signature for any
decorated action.

- DAL(...,migrate_enabled=False) to disable all migrations
- DAL(...,fake_migrate_all=True) to rebuild all corrupted metadata
- new DAL metadata format (databases/*.table)
- DAL(...,adapter_arg={}) allows support for alternate drivers
- DAL now allows circular table defintions
- DAL(..,auto_import=True) automatically imports tables from metadata
without need to db.define_table(...)s.
- new alterante syntax for inner joins: db(...).select(join=...)
- experimental cubrid database support
- DAL 'request_tenant' fields are special, the altomatically filer all
records based on their default value.
- db._common_fields.append(Field('owner')) allows to add fields to ALL
tables
- DAL ignores repeated fields with same names

- web2py_ajax.html is more modular, thanks Anthony
- request.is_local
- request.is_http
- new sessions2trash.py thanks Jim Karsten
- corrupted cache files are automatically deleted
- new simpler API gluon.contrib.AuthorizeNet.procss(...)
- fixed recaptcha (as they released new API)
- messages in validators have default internationalization
- No more Auth(globals(),db), just Auth(db). Same for Crud and
Service.
- scripts/access.wsgi allows apache+mod_wsgi to delegate
authentication of any URL to any web2py app
- json now supports T(...)
- scripts/setup-web2py-nginx-uwsgi-ubuntu.sh
- web2py HTTP responses now set: "X-Powered-By: web2py", thanks Bruno
- mostly fixed generic.pdf. You can view any page in PDF if you have
pdflatex installed or if your html follows the pyfpdf convention.
- auth.settings.extra_fields['auth_user'].append(Field('country'))
allows to extend auth_* tables without need of definiting a custom
auth_* table. Must be placed before auth.define_tables()
- {{=response.toolbar()}} to help you debug applications
- web based shell now supports object modifications (but no
redefinitions of non-serializable types)
- jQuery 1.6.1
- Lots of bug fixes

Great release. I've been waiting for a stable release to move into production which I will probably stay with for awhile.

[Massimo Di Pierro]

Give it a day or to since new bugs always popup after a release with
so many changes.

[szimszon]

- URL(...,user_signature=True), LOAD(...,user_signature=True) can sign
urls and @auth.requires_signature() will check the signature for any
decorated action.

Sorry for a stupid question but what is an url signature how does it work?

[Massimo Di Pierro]

Not a stupid question. Consider this code:

def index():
if user_has_permission_to_call_other():
link = A('click',_href=URL('other'))
else:
link = DIV('do nothing')
return dict()

def other():
if not user_has_permission_to_call_other():
redirect(URL('index'))
return dict()

The code is checking twice whether the
user_has_permission_to_call_other. You must check twice else you
display the link to users who do not have access or you expose the url
to users who do not have access. The same problem applies to
callbacks. Now you can do:

def index():
if user_has_permission_to_call_other():
link = A('click',_href=URL('other',user_signature=True))
else:
link = DIV('do nothing')
return dict()

@auth.requires_signature()
def other():
return dict()

Now the check is done in one single place. The code is faster and
cleaner.

The url in the link is "signed" by appending a ?_signature=<code> that
is only valid for this user during this session. Even if URL('other')
where to be made public accidentally, nobody else could access it. The
signature (the <code> string) is a HMAC hash using private key for the
session. It contains a hash of the full url including all parameters
passed to it.

[Niphlod]

from what I can see it pushes further variuos uses of the "old"
functions "from gluon.html import verifyURL" to verify the hashed URL
and URL(hmac_key='...') to generate the hashed one. Basically it's a
method that "appends" a variable (as
"_signature=djhdsajhdasjhdasjhdas" parameter in the URL) to allow only
the designated user access the specified URL. (nice for protecting
some ajax calls, for example ^_^)

[Pystar]

auth.settings.extra_fields['auth_user'].append(Field('country'))

does this new release allow me to remove fields from the auth table?
e.g. auth.settings.extra_fields['auth_user'].remove(Field('country'))?
Thanks Max, great release.

[Massimo Di Pierro]

You can add fields before the table is defined. You cannot add or
remove fields after the table is defined. You also cannot remove
fields before the table is defined. I could add this but it would be
less transparent that just make a custom table.

[pbreit]

I saw in the changesets some notes about salts and smart_hashes. Is it now possible to salt password hashes?

[Pystar]

Ok, if I can not do

"auth.settings.extra_fields['auth_user'].remove(Field('country'))? "

can I do something like similar to this "SQLFORM(database.table,
fields["a", "b"])"?
Since I can not remove fields from the auth table, then I can add the
fields I want and display them only.
Thanks

[Massimo Di Pierro]

There is nothing new in this respect. I think you can salt the
password in this way:

import uuid
session._salt = session._salt or str(uuid.uuid4()
auth.settings.extra_fields['auth_user'].append(Field('salt',writable=False,readable=False,default=session._salt))
auth.define_tables()
...
if auth.user: session._salt=auth.user.salt
db.auth_user.password.requires=CRYPT(auth.settings.hmac_key
+session._salt)

give it a try.

Hi, please, give some comments about new features:

While using ide's like pycharm, there are some problems with
completion and discover of web2py internal variables like request,
response, this new feature should improve ide support, but it's
happened so that in the code we use response and request, and "from
gluon import *" feature imports current.response and current.request.
How can I fix this? I mean what should I place in gluon to help ide
understand "request" without "current"?


> - request.is_local
If I understand correctly this function checks whether app is working
on localhost, if so, then maybe it will be really simple to add
another feature - while working on localhost(mostly development mode),
when something raises an error, show not link to ticket, but straight
debug info page, just skip "clicking on ticket link" step - this will
speed up dev process.

Thank you for making web2py better )

I think you can do

if False:
from gluon import *; globals().update(current.__dict__)

but I did not try.

The problem is that one cannot reliably determine whether the client
is on localhost.
request.is_local is a guess, not a certainty. Moreover the user may be
local but not the administrator since there may be more users local on
the same machine.

[Pierre Thibault]

But there is another cool feature in the trunk. If you look in gluon/custom_import.py, you will see two new functions: is_tracking_changes and track_changes. Call track_changes with True and web2py will track the changes made to all Python module source files you are using. The new importer will automatically reload the last version available at the next import statement. Of course, is_tracking_changes() gives the current status.

What could be better? Well, the import tracking feature is generic so you can use it in any Python project. If you want to use it outside web2py, use the version available at http://code.google.com/p/neo-i...

Take a look at Martin's blog: http://martin.tecnodoc.com.ar/default/post/2011/05/13/20_optimize-your-web2py-app-using-the-new-import-method

some really nice features there that make web2py more like typical python scripts. Fantastic!  

[Alessandro Iob]

I have tried the new modules import feature (from mymodule import *, looks for mymodule in applications/thisapp/ modules first and then in sys.path. No more need for local_import) and it works wonderfully on OS/X but not at all on Windows. Below you can find the traceback.

Hello Alessandro,

I wrote this code but I don't have Windows to do testing. I suspect it is a problem related to os.stat.

Can you run this code on your machine and gave me the result?

import os
print os.stat("path to the module you want to import").st_mtime

[Alessandro Iob]

Hi Pierre,

this is the output of the code from the web2py application shell:

web2py Shell Version 1.96.2 (2011-06-03 16:11:39)

In [1] : from selfgroup.castalia import config

In [3] : print os.stat("C:\web2py\\applications\Castalia\modules\selfgroup\castalia\__init__.py").st_mtime

.

Thank you very much,

Alessandro

[weheh]

Amazing release! Congrats to all who helped. I came across some stuff
while testing:

- If I change auth=Auth(globals(),db) to auth=Auth(db) I get a ticket:

Traceback (most recent call last):

File "N:\web2py\gluon\restricted.py", line 188, in restricted
exec ccode in environment
File "N:/web2py/applications/YAKiToMe/models/0_1_db.py", line 15, in
<module>
auth=Auth(db)
File "N:\web2py\gluon\tools.py", line 782, in __init__
auth = session.auth
AttributeError: 'NoneType' object has no attribute 'auth'

- Where do you recommend I put the gluon import *? Does it belong in
every controller or just one of the models? I tried a couple of
different places but the results in Eclipse were confusing.

[pbreit]

I have this:

from gluon.tools import Auth

auth = Auth(db)

[weheh]

I already had

from gluon.tools import *

# the new way
auth=Auth(db) # this causes error

# the old way
auth=Auth(globals(),db) # still works

That seems OK. I don't know. My power is very limited here because I don't have a Windows machine. I guess someone else will have to debug it. In that case, I'll be happy to assist.  What else can I say??

[Alessandro Iob]

If I'll find some free time I'll have a look at the code.

Thank you very much for the help!

No, it does not work. And the problem is not related to the _DateTrackerImporter as I'm not using the track_changes options.

I've made some tests and I've found that in _Web2pyImporter.__call__ the code reaches the "import like 'from x import a, b, ...'" section with the vars set to:

name = selfgroup.castalia 

caller_file_name = C:\w2p\web2py\applications\castalia\controllers/default.py 

self.web2py_path = C:\w2p\web2py 

match_app_dir = <_sre.SRE_Match object at 0x018B7420> 

modules_prefix = applications.castalia.modules

module_prefix + '.' + name = applications.castalia.modules.selfgroup.castalia 

fromlist = ('config',) 

level = -1

then the call to

super(_Web2pyImporter, self).__call__(

modules_prefix+"."+name, globals, locals, fromlist, level

)

raises the ImportError exception (No module named castalia.modules.selfgroup.castalia).

The sys.path seems correct:

['', 'C:\\w2p\\web2py\\site-packages', 'C:\\w2p\\web2py', 'C:\\w2p\\web2py\\gluon', 'C:\\w2p\\web2py\\library.zip']

No clue.

There is something weird here. You said that:

module_prefix + '.' + name = applications.castalia.modules.selfgroup.castalia

super(_Web2pyImporter, self).__call__(

modules_prefix+"."+name, globals, locals, fromlist, level

)

But the error is:

raises the ImportError exception (No module named castalia.modules.selfgroup.castalia).

I would expect "No module named applications.castalia.modules.selfgroup.castalia".

Why is "applicaitons" missing?

"applications.castalia.modules.selfgroup.castalia" is just the value you
get from "module_prefix + '.' + name", that's the value passed to the
__import__ call.

I've tested it with a python 2.6 interpreter. It returns the same error
as in web2py.

I've also created a simple module under applications/castalia/modules
but I can not import it too.

[Alessandro Iob]

Found something: the application folder is named 'Castalia' with the
first char in uppercase, while the importer tries to import it as
'applications.castalia....', in lowercase.

I've tried from the python shell to import using
applications.Castalia..... and it worked.

I've tried from the python shell to import using applications.Castalia..... and it worked.

Problem solved?

No, because the web2py code (under Windows only) keeps trying to import
it in lowercase. I can just rename the application (and it works that
way), but I think this is just a workaround and not a solution to a
problem that should not exist.

No, it does not work. And the problem is not related to the _DateTrackerImporter as I'm not using the track_changes options.

I've made some tests and I've found that in _Web2pyImporter.__call__ the code reaches the "import like 'from x import a, b, ...'" section with the vars set to:

name = selfgroup.castalia 

caller_file_name = C:\w2p\web2py\applications\castalia\controllers/default.py 

self.web2py_path = C:\w2p\web2py 

match_app_dir = <_sre.SRE_Match object at 0x018B7420> 

modules_prefix = applications.castalia.modules

module_prefix + '.' + name = applications.castalia.modules.selfgroup.castalia 

fromlist = ('config',) 

level = -1

then the call to

super(_Web2pyImporter, self).__call__(

modules_prefix+"."+name, globals, locals, fromlist, level

)

raises the ImportError exception (No module named castalia.modules.selfgroup.castalia).

The sys.path seems correct:

['', 'C:\\w2p\\web2py\\site-packages', 'C:\\w2p\\web2py', 'C:\\w2p\\web2py\\gluon', 'C:\\w2p\\web2py\\library.zip']

No clue.

When you are using "Castalia" as the name of your application, is all code values above appears with "castalia" in lower case?

I have fixed the problem adding the following code in one of my models:

import os
os.environ['PYTHONCASEOK'] = '1'

It makes ignore path case on operating systems with case-insensitive
file-systems (namely Win32 and OS/X with the default fs).

Do you think it should be added, with a proper os test, to the importer
code?

No. Now that we know the problem, or that we have enough information to easily locate the lines of code in problem, we can fix these lines. We need someone who can do it on Windows.

I don't like the idea of global change of the Python environment. A local fix is far better solution and it should not very difficult to do in this case.

Thank you for your collaboration.
