try:
rv = url_adapter.build(endpoint, values, method=method,
force_external=external)
except BuildError, error:
# We need to inject the values again so that the app callback can
# deal with that sort of stuff.
values['_external'] = external
values['_anchor'] = anchor
values['_method'] = method
return appctx.app.handle_url_build_error(error, endpoint, values)
rv = url_adapter.build(endpoint, values, method=method,
force_external=external)
If no exception was raised for url_adapter.build(...) then the same method call
would be made after the try...except block. This is unnecessary.
The implementation was not clean and generally the needs for padded json
are disappearing now that all browsers support cross site communication
with the regular xmlhttprequest.
Prior to this commit, the send_file max-age hook and config were only
used for the static file handler. Now they are used when calling
helpers.send_file directly.
This method receives the name of a static file that is going to be served
up and generates a dict of options to use when serving the file. The
default set is empty so code will fall back to the existing behavior if
the method is not overridden.
I needed this method to adjust the cache control headers for .js files that
one of my applications was statically serving. The default expiration is
buried in an argument to send_file and is set to 12 hours. There was no
good way to adjust this value previously.
In the snippet 'session.setdefault(...).append(...)', it was being
assumed that changes made to mutable structures in the session are
are always in sync with the session object, which is not true for
session implementations that use a external storage for keeping their
keys/values.
This avoids errors in creating Flask instances where there are import
errors in the module or package matching the import name. Those runtime
errors will be apparent to the user soon enough, but tools which build
Flask instances meta-programmatically benefit from a Flask which does
not __import__.
