This reverts commit 2e9677b7c3f37e9627b9cbc9a6ddec82a10e7215.
Third time is the charm. I hid it from reflection, but I missed `get_class_methods`.
The diff betweenn this and what was reverted is https://phabricator.fb.com/P2217891 and then I did https://phabricator.fb.com/P2217904 because it looked like it should be done.
Closures and generators are really hard to reason about in backtraces.
For generators, I took the exact name of the method and put ##$continuation##. I put it at the end so it reads exactly like a method name since in WWW we use them almost the same as the method itself.
For closures, I named the class ##Closue$Class::method#num## where num is an optional autoincrementing number.
I decided to stop prefixing the methods with ##0## which is breaking the reflection tests.
This basically redoes D782498 and D750608 but it works in repo mode.
I was learning from @jdelong and he said that you should use
double quotes for local includes and angle brackets for library
includes. I asked why our code was the way it was, and he said he wanted
to clean it up. I beat him to it :)

Update a number of things to make optionally generating the parser at
build time possible. @sgolemon will add the OSS pieces of this in a
separate commit.
The unserialization of random objects may be dangerous because the destructor of the object will be called when the unserialized objects are out of scope. However, the person who wrote the class may not be aware of the danger of unserialization. Therefore, we would like to require every users of the unserialize() to provide a whitelist of the class names that are authorized to be unserialized so that we can make sure the object is safe to be unserialized.
Add a parameter 'class_whitelist' to unserialize() function to determine whether to raise warnings for unsafe unserialization. If the class to be unserialized is not an instance of Serilizable or not in the whitelist, warnings will be raised. For the detailed reason why we need this, please see http://fburl.com/SafeSerializable for more information.
Add a parameter 'all_classes_enabled' to allow those hphp functions that need to unserialize any class. For example, fb_call_user_func_async() will need to serialize and nserialize the given parameters.
A small change to optimize very simple binary operators in the parser. This avoids building very large parse trees for super-large expressions and folds binary operators involving two scalars directly in the parser. I've limited this to simple scalars since it's easy to prove they don't have anything too interesting going on in the other analysis phases leading up to BinaryOpExpression's normal folding. This works for all binary operators.
unserialize() and call_user_func_array() were straightforward. They were
called from all over the runtime, but I renamed those implementations
and codemodded the runtime.
The is_* functions were only ever being called by the CVarRef signature,
so I deleted all the other ones (same for f_gettype). Only some of the
is_* functions were being called from the runtime, so I made inline
versions of those without the f_ prefix.
Instead of having the body of the closure be in the ##__invoke()## on the ##Closure## class, instead we make an anonymous function on the real class and put the body there. The signature for this function is:
function methodForClosure$1234($arg1, $arg2, ..., $use1, $use2, ...)
and then ##__invoke## now just takes all the params that were passed to it, puts them as the first args to the anonymous function, then takes all the use variables it had saved up and passed them in as the next params.
I tried to not have an ##__invoke## at all, but I ended up basically doing the same parameter and use var repacking in iopFCall (and would have had to do it in x86 code too). I opted for doing the rejiggering in bytecode. If I did it in raw PHP I think it would have been much slower with many ##func_get_args()## and array operations.
g++-4.7.1 treats "FOO"bar as a c++-11 literal operator, even
if bar is a macro with an expansion such as "BAR" - so add a space
after the quote (this seems like a bug, and I fixed a bunch of these
a while ago, but we just added a slew of PRI*64 macros which break
under 4.7.1).
Also, it warned that "explicit by-copy capture of 'this' redundant"
for a lambda declared [=, this] - so I removed the this.
We also needed more than the 60 levels of template expansion that was
allowed by the makefile.
For "$obj->{__FUNCTION__}" and "$obj->{__CLASS__}", we currently don't
recognize __FUNCTION__ and __CLASS__ as "magic constants" and we just use
the literal strings "__FUNCTION__" and "__CLASS__" for the property names.
This is wrong. Same goes for object method calls (ex. "$obj->{..}(..)").
This diff fixes HipHop to recognize magic constants for properties names in
"$obj->{..}" expressions and method names in "$obj->{..}(..)" expressions.
Per @mwilliams' suggestion, this is the first stage in a staggered approach to replacing int64 with int64_t. More precisely I inserted "typedef ::int64_t int64;" in util/base.h and dealt with the consequences.
This change is mostly for FB internal organizational reasons.
Building is not effected beyond the fact that the target now
lands in hphp/hhvm/hhvm rather than src/hhvm/hhvm.
