WSGI application for the zope.publisher

## Project description

This package provides the WSGIPublisherApplication class which exposes the object publishing machinery in zope.publisher as a WSGI application. It also lets us bring up the Zope application server (parsing zope.conf and site.zcml) with a mere function call:

>>> db = zope.app.wsgi.config('zope.conf')

This is especially useful for debugging.

To bring up Zope and obtain the WSGI application object at the same time, use the getWSGIApplication function.

This package also provides an easy to use application factory for PasteDeploy. You can simply specify an application configuration like this in your Paste configuration file:

[app:main]
use = egg:zope.app.wsgi
config_file = %(here)s/zope.conf

Look for more documentation inside the package itself.

## CHANGES

### 5.0 (2023-01-19)

• Add support for Python 3.11.

• Add support for Python 3.10.

• Drop support for Python 2.7, 3.5, 3.6.

### 4.4 (2022-07-13)

• Add support for Python 3.9.

• Remove unused dependencies on zope.configuration, zope.error, zope.lifecycleevent, zope.session, zope.testing, and unused test dependencies on zope.annotation, zope.login, and zope.password.

### 4.3.0 (2020-07-06)

• Fix the testlayer’s http() to pass through the request protocol as the response protocol, for compatibility with zope.app.testing.functional’s HTTPCaller. See PR 21.

### 4.2.0 (2020-03-23)

• Add support for Python 3.7 and 3.8.

• Drop support for Python 3.3 and 3.4.

• Fix the testlayer’s http() to accept leading whitespace in HTTP requests, for compatibility with zope.app.testing.functional’s HTTPCaller.

• Add a server_protocol attribute to FakeResponse so you can customize the output to be more compatible with zope.app.testing.functional’s HTTPCaller.

• Drop support for running the tests using python setup.py test.

### 4.1.0 (2017-04-27)

• Use base64.b64encode to avoid deprecation warning with Python 3.

• Add support for Python 3.6.

• Fix the testlayer’s FakeResponse assuming that headers were in unicode on Python 2, where they should usually be encoded bytes already. This could lead to UnicodeDecodeError if the headers contained non-ascii characters. Also make it implement __unicode__ on Python 2 and __bytes__ on Python 3 to ease cross version testing. See issue 7.

### 4.0.0 (2016-08-08)

• Update dependencies to no longer pin alpha versions of packages which already have final releases.

• Drop support for Python 2.6.

• Claim support for Python 3.4 and 3.5. This requires to update to

• zope.app.appsetup >= 4.0

• zope.app.publication >= 4.0

• Fix a bug occurring in Python 3 when the principal could not be adapted to ILoggingInfo.

### 4.0.0a4 (2013-03-19)

• Improve Trove classifiers.

• Fix BrowserLayer(allowTearDown=True) to actually allow tear downs.

### 4.0.0a3 (2013-03-03)

• You can now specify additional WSGI middleware components wihtout subclassing the BrowserLayer class.

• tox now uses the Zope test runner’s ftest command to execute tests, since setup tests cannot deal with layers, especially when they need to spawn sub-proceeses.

• Switched all functional tests to use WebTest instead of zope.testbrowser. Set up proper layering.

• Do not rely on zope.testbrowser.wsgi WSGI layer support. It was not needed anyways.

• Minimized the ftesting.zcml setup.

• Backwards incompatibility: if you depend on zope.app.wsgi.testlayer, you will need to require zope.app.wsgi[testlayer] >= 4.0 (version constraint is there because older zope.app.wsgi releases did not define a testlayer extra).

### 4.0.0a2 (2013-03-02)

• Fixed a bug in WSGI Test Layer setup, where the DB is not correctly set.

### 4.0.0a1 (2013-02-28)

• Added support for Python 3.3.

• Replaced deprecated zope.interface.implements usage with equivalent zope.interface.implementer decorator.

• Dropped support for Python 2.4 and 2.5.

### 3.15.0 (2012-01-19)

• Fixed: zope.app.wsgi.paste.ZopeApplication didn’t emit ProcessStarting events.

NOTE

If an application compensated for this by generating the event, it will need to stop or there will be multiple events emited. (Whether or not multiple events will do any harm is application specific.)

### 3.14.0 (2012-01-10)

• Set the WSGI environment’s REMOTE_USER item (if not already set) with the Zope principal label. (This is the same data set in the wsgi.logging_info environment item.)

This change allows user info to be used by paste.translogger middleware (or any similar middleware that uses REMOTE_USER), which provides access logging.

### 3.13.0 (2011-03-15)

• Update to zope.testbrowser 4.0.0 which uses WebTest instead of wsgi_intercept.

### 3.12.0 (2011-01-25)

• Fixed zope.app.wsgi.testlayer.http to work with changes made in version 3.11.0.

### 3.11.0 (2011-01-24)

• Moved wsgi_intercept support to zope.testbrowser.wsgi, thus requiring at least version 3.11 of this package:

• Moved zope.app.wsgi.testlayer.Browser to zope.testbrowser.wsgi.Browser, but left BBB import here.

• Split up zope.app.wsgi.testlayer.BrowserLayer into generic WSGI browser layer (zope.testbrowser.wsgi.Layer) and ZODB/ZOPE specific part (zope.app.wsgi.testlayer.BrowserLayer as before).

### 3.10.0 (2010-11-18)

• Add pluggability for setting up WSGI middleware in testlayer.

### 3.9.3 (2010-10-14)

• Python 2.7 compatibility for xmlrpc. Transplant of zope.app.testing r116141.

### 3.9.2 (2010-05-23)

• Fixed test breakage due to changes in mechanize 0.2.0.

### 3.9.1 (2010-04-24)

• Add support for testing XMLRPC using zope.app.wsgi.testlayer.

• Fix a bug in the status string handling in zope.app.wsgi.testlayer’s FakeResponse.

### 3.9.0 (2010-04-19)

• Return a FakeResponse object in zope.app.wsgi.testlayer.http, so it becomes easier to port over tests from zope.app.testing’s HTTPCaller.

• X-Powered-By header is now stripped by zope.app.wsgi.testlayer as it is by zope.app.testing.

• Bugfix: initialize any <logger> defined in the config, as zope.app.server does. (Fixes #291147)

### 3.8.0 (2010-04-14)

• zope.app.wsgi.testlayer is now a lot more compatible with the HTTPCaller() functionality in zope.app.testing, which it can replace:

• same transaction behavior - pending transactions are committed before request and synchronized afterwards.

• support for browser.handleErrors (for zope.testbrowser).

• support for clear-text (non-base64) Basic authentication headers, which are easier to read in the tests (though not correct in actual HTTP traffic).

### 3.7.0 (2010-04-13)

• Rewrite tests in order not to dependent on zope.app.testing and zope.app.zcmlfiles.

• zope.app.wsgi.testlayer introduces new testing functionality that can replace the old functionality in zope.app.testing. In addition, it supports using zope.testbrowser with WSGI directly (instead of relying on zope.app.testing, which pulls in a lot of dependencies).

The interesting parts are:

• zope.app.wsgi.testlayer.BrowserLayer: this sets up a minimal layer that allows you to use the new WSGI-enabled Browser.

• zope.app.wsgi.testlayer.Browser: this is a subclass of Browser from zope.testbrowser.browser. Use it instead of zope.testbrowser.browser directly to use the test browser with WSGI. You need to use BrowserLayer with your tests for this to work.

• zope.app.wsgi.testlayer.http: this is the equivalent to the http() function in zope.app.testing. It allows low-level HTTP access through WSGI. You need to use BrowserLayer with your tests for this to work.

### 3.6.1 (2010-01-29)

• Support product configuration sections in Zope configuration files.

### 3.6.0 (2009-06-20)

• Import database events directly from zope.processlifetime instead of using BBB imports in zope.app.appsetup.

### 3.5.2 (2009-04-03)

• The WSGIPublisherApplication uses now the ILoggingInfo concept given from zope.publisher.interfaces.logginginfo for log user infos usable for access logs. This allows you to implement your own access log user info message. See zope.publisher.interfaces.logginginfo.ILoggingInfo for more information.

### 3.5.1 (2009-03-31)

• The WSGIPublisherApplication call now provides a user name in the environment meant for use in logs.

### 3.5.0 (2009-02-10)

• Make devmode warning message more generic. We don’t nesessary have the etc/zope.conf file nowadays when using buildout-based setups.

• Add an application factory for Paste. So Zope application can now be easily deployed with Paste .ini configuration like this:

[app:main]
use = egg:zope.app.wsgi
config_file = %(here)s/zope.conf
handle_errors = false

The config_file is a required argument, however the handle_errors defaults to True if not specified. Setting it to False allows you to make WSGIPublisherApplication not handle exceptions itself but propagate them to an upper middleware, like WebError or something.

• The WSGIPublisherApplication constructor and getWSGIApplication function now accept optional handle_errors argument, described above.

• Change mailing list address to zope-dev at zope.org instead of retired one.

### 3.4.1 (2008-07-30)

• Notify WSGIPublisherApplicationCreated event when WSGI application is created.

• Fixed deprecation warning in ftesting.zcml: ZopeSecurityPolicy moved to zope.securitypolicy.

### 3.4.0 (2007-09-14)

• Fixed the tests to run on Python 2.5 as well as Python 2.4.

• Split getApplication into config and getApplication so that config could be reused, for example for debugging.

### 3.4.0a1 (2007-04-22)

Initial release as a separate project, corresponds to zope.app.wsgi from Zope 3.4.0a1
