Generator::throw($exception) throws an exception into the generator. The
exception is thrown at the current point of suspension within the generator.
It basically behaves as if the current yield statement were replaced with
a throw statement and the generator subsequently resumed.
I know that in general NEWS is a very punchy "this is what happened" log, but
Chris e-mailed me off-list to ask if it could be added to avoid any FUD — this
merely brings the NEWS post into line with UPGRADING, the migration guide, and
every other piece of advice we're giving out.
I also forgot to add the RFC URL last night, so added that.
Per https://wiki.php.net/rfc/mysql_deprecation, connecting to a MySQL database
via ext/mysql now generates an E_DEPRECATED error. This commit includes the
minimal EXPECTF updates required for the test suite to pass: it may be
preferable to refactor some of the tests to suppress deprecation errors in
situations where no other error is expected from mysql_[p]connect(), but I'm
not enough of a MySQL expert to want to get my hands that dirty in a long
standing test suite.
Added 2nd, optional, param to assert. When passed in it will be added
to the printed warnings and passed as a 4th param to a callback. PR 150
by Lonny Kapelushnik
This change is as per RFC https://wiki.php.net/rfc/empty_isset_exprs.
The change allows passing the result of function calls and other
expressions to the empty() language construct. This is accomplished by
simply rewriting empty(expr) to !expr.
The change does not affect the suppression of errors when using empty()
on variables. empty($undefinedVar) will continue not to throw errors.
When an expression is used inside empty() on the other hand, errors will
not be suppressed. Thus empty($undefinedVar + $somethingElse) *will*
throw a notice.
The change also does not make empty() into a real function, so using
'empty' as a callback is still not possible.
In addition to the empty() changes the commit adds nicer error messages
when isset() is used on function call results or other expressions.
