improve REST interface security
When using REST, we reflect the client's origin. If the wildcard '*'
is used in allowed_api_origins all origins are allowed. When this is
done, it also added an 'Access-Control-Allow-Credentials: true'
header.
This Credentials header should not be added if the site is matched
only by '*'. This header should be provided only for explicit origins
(e.g. https://example.org) not for the wildcard.
This is now fixed for CORS preflight OPTIONS request as well as normal
GET, PUT, DELETE, POST, PATCH and OPTIONS requests.
A missing Access-Control-Allow-Credentials will prevent the tracker
from being accessed using credentials. This prevents an unauthorized
third party web site from using a user's credentials to access
information in the tracker that is not publicly available.
Added test for this specific case.
In addition, allowed_api_origins can include explicit origins in
addition to '*'. '*' must be first in the list.
Also adapted numerous tests to work with these changes.

TAL - Template Attribute Language --------------------------------- This is an implementation of TAL, the Zope Template Attribute Language. For TAL, see the Zope Presentation Templates ZWiki: http://dev.zope.org/Wikis/DevSite/Projects/ZPT/FrontPage It is not a Zope product nor is it designed exclusively to run inside of Zope, but if you have a Zope checkout that includes Products/ParsedXML, its Expat parser will be used. Prerequisites ------------- You need: - A recent checkout of Zope2; don't forget to run the wo_pcgi.py script to compile everything. (See above -- this is now optional.) - A recent checkout of the Zope2 product ParsedXML, accessible throught <Zope2>/lib/python/Products/ParsedXML; don't forget to run the setup.py script to compiles Expat. (Again, optional.) - Python 1.5.2; the driver script refuses to work with other versions unless you specify the -n option; this is done so that I don't accidentally use Python 2.x features. - Create a .path file containing proper module search path; it should point the <Zope2>/lib/python directory that you want to use. How To Play ----------- (Don't forget to edit .path, see above!) The script driver.py takes an XML file with TAL markup as argument and writes the expanded version to standard output. The filename argument defaults to tests/input/test01.xml. Regression test --------------- There are unit test suites in the 'tests' subdirectory; these can be run with tests/run.py. This should print the testcase names plus progress info, followed by a final line saying "OK". It requires that ../unittest.py exists. There are a number of test files in the 'tests' subdirectory, named tests/input/test<number>.xml and tests/input/test<number>.html. The Python script ./runtest.py calls driver.main() for each test file, and should print "<file> OK" for each one. These tests are also run as part of the unit test suites, so tests/run.py is all you need. What's Here ----------- DummyEngine.py simple-minded TALES execution engine TALInterpreter.py class to interpret intermediate code TALGenerator.py class to generate intermediate code XMLParser.py base class to parse XML, avoiding DOM TALParser.py class to parse XML with TAL into intermediate code HTMLTALParser.py class to parse HTML with TAL into intermediate code HTMLParser.py HTML-parsing base class driver.py script to demonstrate TAL expansion timer.py script to time various processing phases setpath.py hack to set sys.path and import ZODB __init__.py empty file that makes this directory a package runtest.py Python script to run file-comparison tests ndiff.py helper for runtest.py to produce diffs tests/ drectory with test files and output tests/run.py Python script to run all tests Author and License ------------------ This code is written by Guido van Rossum (project lead), Fred Drake, and Tim Peters. It is owned by Digital Creations and can be redistributed under the Zope Public License. TO DO ----- (See also http://www.zope.org/Members/jim/ZPTIssueTracker .) - Need to remove leading whitespace and newline when omitting an element (either through tal:replace with a value of nothing or tal:condition with a false condition). - Empty TAL/METAL attributes are ignored: tal:replace="" is ignored rather than causing an error. - HTMLTALParser.py and TALParser.py are silly names. Should be HTMLTALCompiler.py and XMLTALCompiler.py (or maybe shortened, without "TAL"?) - Should we preserve case of tags and attribute names in HTML?
