paste

Fixed parsed_formvars potentially locking up on wsgi.input after modification of QUERY_STRING.

Fixed problem where paste.exceptions.errormiddleware didn't expose the .close() method of the app_iter that it wraps (to catch exceptions). This is a problem if the server about the errormiddleware aborts the request; it should then call .close(), but won't necessarily exhaust the iterator to do so.

Added entry point for paste.translogger (egg:Paste#translogger)

Fixed some cases where long data (e.g., a file upload) would show up in the error report, creating a very very large report. Also, put in a monkeypatch for the cgi module so that repr(uploaded_field) won't load the entire field into memory (from its temporary file location).

Added a force_host option to paste.proxy.TransparentProxy, which will force all incoming requests to the same host, but leave the Host header intact.

Added automatic cleanup of old sessions for paste.session, from Amir Salihefendic.

Quote the function name in tracebacks in the exception formatter; Genshi has function names that use <>.

Fixed wsgiwrappers.WSGIResponse.delete_cookie. It also now takes optional path and domain arguments

wsgiwrappers.WSGIResponse now handles generator/iterator content more cleanly, and properly encodes unicode content according to its specified charset

Fixed wsgiwrappers.WSGIResponse mishandling multiple headers of the same name

Added a Paste Deploy entry point for paste.auth.cookie

Moved Paste Deploy dependencies out of top-level modules and into Paste-Deploy-specific entry point functions. This should make Paste more-or-less Paste Deploy independent. paste.urlparser and paste.exceptions.errormiddleware still have some leftover bits.

Added another redirector type to paste.recursive, environ['paste.recursive.include_app_iter'] which gives access to the original app_iter.

Bug with wsgilib.catch_errors and app_iters with no close() method.

Long words in tracebacks weren't being wrapped correctly at all. Also, large data would cause the wrapping routine to give a recursion error. Now large data is truncated (at 1000 characters), and recursion won't be a problem. Also, wrapping shouldn't lose characters.

Better exception if you try to put a non-str into environ when using paste.auth.cookie

paste.exceptions.collector produces an exc_data.exception_type that is a class, not a string. This helps it get formatted better in Python 2.5.

All the tests pass on Python 2.5!

Added paste.proxy.TransparentProxy, which just sends the request described in the WSGI environ on without any modification. More useful for WSGI clients than servers, it effectively allows any WSGI-based request mechanism to act like an httplib-based request mechanism.

Added a cache_max_age argument to paste.urlparser.StaticURLParser, which allows you to encourage the caching of static files. Patch from Brad Clements.

Added suppress_http_headers to paste.proxy.Proxy, which will filter out HTTP headers from the request before passing it on. Patch from Brad Clements.

The EvalException 'full traceback' button is now only displayed when the full traceback differs from the regular (includes hidden frames).

Fixed EvalException returning a Content-type of 'text-html' instead of 'text/html' in some cases.

Fixed a security vulnerability in paste.urlparser's StaticURLParser and PkgResourcesParser where, with some servers, you could escape the document root.

Significantly improved paste.httpserver's (egg:Paste#http) performance. It now uses a thread pool: previously it created a new thread for every request. To revert back to the old, slower behavior, set::

use_threadpool = false

in the [server:main] section of the config file.

More control of where the output of paste.debug.prints goes.

Added a warning to paste.wsgilib.add_close if the upstream app_iter consumer doesn't call the app_iter.close() method.

Fixed testapp.post(params={})

Fixed paste.translogger.TransLogger to log to the Apache combined log format as advertised.

Fixed paste.urlparser classes to handle quoted characters (e.g. %20) in URL paths.

Changed paste.session to allow manipulating a session for the first time after start_response is called.

Added paste.wsgilib.add_start_close which calls a function just before returning the first chunk of the app_iter.

Changed paste.urlmap so that it matches domain-specific mappings before domain-neutral mappings.

Fixed IE 6 potentially receiving the following "400 Bad Request" error on file downloads::

Please check your system clock. According to this server, the time provided in the If-Modified-Since header is in the future.

Added a 'no' keyword argument to TestResponse.mustcontain, so you can assert that a response does contain some strings at the same time that you assert that a response does not contain other strings, like::

res = app.get('/') res.mustcontain('this must be there', no=['error', 'unexpected'])

Fixed fileapp.FileApp to pay attention to the If-None-Match header, which does ETag matching; before only If-Modified-Since was supported, even though an ETag header was being sent; in particular Firefox would then only send If-None-Match and so conditional requests never worked.

Changed usage of paste.request.MultiDict to paste.util.multidict, particularly in paste.wsgiwrappers where request.GET returns a new style of dictionary interface.

Be more careful in paste.request.parse_formvars not to let the cgi module read from wsgi.input when there are no parsable variables in the input (based on CONTENT_TYPE).

0.9.2 Included a version of MochiKit that was no longer compatible with evalexception; 0.9.3 reverts to a previous version.

Change wsgi.run_once=False for paste.httpserver

Added entry points for debug apps

Fix in paste.urlmap when connecting with host:port.

Added /_debug/summary to evalexception, which gives a JSON-formatted list of all the exceptions in memory.

Added paste.request.WSGIRequest <class-paste.request.WSGIRequest.html>_, a request object that wraps the WSGI environment.

Added paste.registry <module-paste.registry.html>_, which is middleware for registering threadlocal objects in a request.

Avoid annoying warning from paste.recursive

paste.httpserver now removes HTTPServer's transaction logging, which was doing a reverse DNS lookup.

Added has_session to paste.session

Allow for conditional paste.wsgilib.intercept_output which should be slightly faster (and streamable) compared to doing the condition manually.

Added entry point for paste.proxy <module-paste.proxy.html>_, plus improvements from Brad Clements (support path in target, filter request methods)

Added paste.pony <module-paste.pony.html>_ so pony power can be added to any WSGI application.

Added port matching to paste.urlmap.

Added paste.auth.auth_tkt <module-paste.auth.auth_tkt.html>_

Added paste.auth.grantip <module-paste.auth.grantip.html>_

Some bug fixes to the built-in HTTP server <module-paste.httpserver.html>_.

Experimental paste.progress <module-paste.progress.html>_ middleware for tracking upload progress

Some tweaking of how paste.reload <module-paste.reload.html>_ works, especially with respect to shutdown.

Fixed up paste documentation (especially for new packages/modules)

Added paste.auth <module-paste.auth.html>_ package for authentication related WSGI middle-ware components:

• basic and digest HTTP authentication as described by RFC 2617

• support for Yale's Central Authentication System (cas)

• open_id supports single sign-on originally developed for LiveJournal (see http://openid.net)

• cookie digitally signs cookies to record the current authenticated user (REMOTE_USER), session identifier (REMOTE_SESSION), and other WSGI entries in the environ.

• a form module (to be used with cookie or an equivalent) provides a simple HTML based form authentication.

• the multi module is an experimental mechanism for choosing an authentication mechanism based on the WSGI environ

Added paste.httpserver <module-paste.httpserver.html>_ module which provides a very simple WSGI server built upon python's BaseHTTPServer; this server has support for several features:

• support for SSL connections via OpenSSL

• support for HTTP/1.1 100 Continue messages as required by the WSGI specification (many HTTP server implementations don't do this)

• implemented as a Mix-In so that it can be used with other more enchanted versions of BaseHTTPServer

• support for 'Keep-Alive' (standard in HTTP/1.1) by either providing a content-length or closing a connection if one is not available

Improved the paste.httpexceptions <module-paste.httpexceptions.html>_ module:

• added missing exception objects, and better descriptions

• fixed several bugs in how exceptions are caught and propagated

• usage as a wsgi_application() enables exceptions to be returned without throwing or catching the error

• support for plain/text messages for text-only clients such as curl, python's urllib, or Microsoft Excel

• allows customization of the HTML template for higher-level frameworks

Added paste.httpheaders <module-paste.httpheaders.html>_ module to provide a uniform mechanism to access/update standard HTTP headers in a WSGI environ and response_headers collection; it includes specific support for:

• providing "common" header names and sorting them as suggested by RFC 2616

• validated support for Cache-Control header construction

• validated support for Content-Disposition header construction

• parsing of If-Modified-Since and other date oriented headers

• parsing of Range header for partial-content delivery

• composition of HTTP/1.1 digest Authorization responses

Improved paste.fileapp <module-paste.fileapp.html>_ to support:

• static in-memory resources

• incremental downloading of files from disk

• responding to 'Range' requests to handle partial downloads

• allowing cache settings to be easily provided; including support for HTTP/1.0 'Expires' and HTTP/1.1 'Cache-Control'

Added an experimental paste.transaction <module-paste.transaction.html>_ module for handling commit/rollback of standard DBAPI database connections

Added a paste.util.datetimeutil <module-paste.util.datetimeutil.html>_ module for parsing standard date/time user-generated text values

Added a debug <module-paste.debug.html>_ package, which includes:

• previous top-level modules prints, profile, wdg_validate and doctest_webapp

• a testserver module suitable to test HTTP socket connections via pytest

Re-factored paste.wsgilib <module-paste.wsgilib.html>_ into several other modules:

• functions regarding header manipulation moved to paste.response <module-paste.response.html>_

• functions regarding cookies and arguments moved to paste.request <module-paste.request.html>_

Significant improvements to wsgiutils.wsgilib module:

• added a dump_environ application to help debugging

• fixes to raw_interactive to comply with WSGI specifications

• raw_interactive now logs all 5xx exceptions and sets HTTP_HOST

Added an argument no_profile to paste.debug.profile.profile_decorator <module-paste.debug.profile.html#profile_decorator>_; if that option is false, then don't profile the function at all.

Changed paste.lint <module-paste.lint.html>_ to check that the status contains a message (e.g., "404 Not Found" instead of just "404"). Check that environmental variables HTTP_CONTENT_TYPE and HTTP_CONTENT_LENGTH are no present. Made unknown REQUEST_METHOD a warning (not an error).

Added parameter cwd to TestFileEnvironment.run <class-paste.fixture.TestFileEnvironment.html#run>_

paste.fixture.TestApp <class-paste.fixture.TestApp.html>_:

• Form filling code (use response.forms[0] to get a form object <class-paste.fixture.Form.html>_)

• Added click method <class-paste.fixture.TestResponse.html#click>_.

• Better attribute errors.

• You can force set hidden fields using form.fields[name].force_value(value) (normally setting the value of a hidden field is an error).

• Frameworks can now add custom attributes to the response object.

paste.wsgilib.capture_output is deprecated in favor of paste.wsgilib.intercept_output <module-paste.wsgilib.html#intercept_output>_

Remove use of exceptions in paste.cascade.Cascade <class-paste.cascade.Cascade.html>_, which causes weird effects in some cases. Generally we aren't using exceptions internally now, only return status codes. Also in cascade, be careful to keep cascaded requests from sharing the same environment.

paste.wsgilib.error_response is deprecated (paste.httpexceptions <module-paste.httpexceptions.html>_ replaces this with exception's .wsgi_application method).

Moved paste.login to the attic, since paste.auth <module-paste.auth.html>_ pretty much replaces it.

paste.urlparser <module-paste.urlparser.html>_ improvements:

• Added an application urlparser.StaticURLParser <class-paste.urlparser.StaticURLParser.html>_ for serving static files.

• Added an application urlparser.PkgResourcesParser <class-paste.urlparser.PkgResourcesParser.html>_ for serving static files found with pkg_resources (e.g., out of zipped Eggs).

• Be less picky about ambiguous filenames when using URLParser <class-paste.urlparser.URLParser.html>_; if an exact file match exists, use that. (file.gif.bak would cause a request for file.gif to be ambiguous before)

• Now looks for a .wsgi_application attribute when serving Python files/modules, as a general hook for returning a WSGI application version of an object.

The ErrorMiddleware <class-paste.exceptions.errormiddleware.ErrorMiddleware.html>_:

• Returns trimmed-down exceptions if there is a _ GET variable in the request (which is meant to signal an XMLHttpRequest). Exceptions displayed in this context are best when they are smaller and easier to display.

• Includes a text version of the traceback, for easier copy-and-paste.

• Avoid printing exceptions to wsgi.errors if they are already displayed elsewhere (at least by default).

• Highlight Python code.

Use pkg_resources.declare_namespace so that there are less problems about confusing the paste package that is provided by Paste, Paste Script, Paste Deploy, and Paste WebKit. Before you could get one of these at random if you didn't use pkg_resources.require first.

Cleaned up use of exc_info argument in start_response calls (both accepting and producing), in a variety of places.
