When debugging a script using a local VM (i.e. when there is no remote VM),
the cleanup actions performed by the run command caused the debugger client
to shut down as well. Since this seems to be intentional, processing of the
run command now restarts the debugger client and proxy. Also, following a
ctrl-C, the m_lastLocFilter field must be cleared, otherwise an empty endless
loop cannot be broken into for a second time.
Hphpd's Jump command has been fundamentally broken for a long time. It was originally implemented to run the byte code in a modified way which didn't make state changes, and wait for the destination offset to be reached. We lost the ability to do that long ago, and the implementation of this command has atrophied since. As it stands now, if you're lucky it might act like "run until", which is the opposite of what it is documented to do.
I've removed the command entirely. Fixing it is a very large effort which we might consider some time in the future.
I found myself getting confused, thinking that proxy->send(cmd) sends a command to the proxy, when in fact it causes the proxy to send the command to the client. These are now named sendToClient, sendToServer and recvFromServer so that future readers (including my future self) will not make this mistake again.
It's enabled if the HPHP_TRACE_FILE is "/dev/stdout" or
"/dev/stderr" and also isatty(), or you can set HPHP_TRACE_TTY in your
environment to override it (e.g. if you like to pass to less -R).
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.
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.
