Zachary Turner 54695a339f Convert GetNameColonValue to return StringRefs.
StringExtractor::GetNameColonValue() looks for a substring of the
form "<name>:<value>" and returns <name> and <value> to the caller.
This results in two unnecessary string copies, since the name and
value are not translated in any way and simply returned as-is.

By converting this to return StringRefs we can get rid of hundreds
of string copies.

Zachary Turner 44c35e80b1 Copy StringExtractor to StdStringExtractor.
I have some improvements to make to StringExtractor that require
using LLVM.  debugserver can't take a dependency on LLVM but uses
this file, so I'm forking it off into StdStringExtractor and
StringExtractor, so that StringExtractor can take advantage of
some performance improvements and readability improvements that
LLVM can provide.

Zachary Turner 9b1669ae35 Remove std::atomic from lldb::Address.
std::atomic<uint64_t> requires 64-bit alignment in order to
guarantee atomicity.  Normally the compiler is pretty good about
aligning types, but an exception to this is when the type is
passed by value as a function parameter.  In this case, if your
stack is 4-byte aligned, most modern compilers (including clang
as of LLVM 4.0) fail to align the type, rendering the atomicity
ineffective.

A deeper investigation of the class's implementation suggests
that the use of atomic was in vain anyway, because if the class
were to be shared amongst multiple threads, there were already
other data races present, and that the proper way to ensure
thread-safe access to this data would be to use a mutex from a
higher level.

Since the std::atomic was not serving its intended purpose anyway,
and since the presence of it generates compiler errors on some
platforms that cannot be workaround, we remove std::atomic from
Address here.  Although unlikely, if data races do resurface
the proper fix should involve a mutex from a higher level, or an
attempt to limit the Address's access to a single thread.

Zachary Turner 26709df81d Convert some functions to use StringRef instead of c_str, len
This started as an effort to change StringExtractor to store a
StringRef internally instead of a std::string.  I got that working
locally with just 1 test failure which I was unable to figure out the
cause of.  But it was also a massive changelist due to a trickle
down effect of changes.

So I'm starting over, using what I learned from the first time to
tackle smaller, more isolated changes hopefully leading up to
a full conversion by the end.

At first the changes (such as in this CL) will seem mostly
a matter of preference and pointless otherwise.  However, there
are some places in my larger CL where using StringRef turned 20+
lines of code into 2, drastically simplifying logic.  Hopefully
once these go in they will illustrate some of the benefits of
thinking in terms of StringRef.

Kate Stone ac9c3a62a1 Tables of command options in LLDB benefit from hand-formatting to make it
easier to scan a set of options with a relatively large number of positional
arguments. This commit standardizes their formatting throughout LLDB and
applies surrounding directives to exempt them from being formatted by
clang-format.

These kinds of exemptions should be rare cases that benefit significantly
from alternative formatting. They also imply a long-term obligation to
maintain their format since the automated tools will not do so.

Pavel Labath 0e947eb636 Add cmake option to choose whether to use the builtin demangler
Summary:
Previously the builting demangler was on for platforms that explicitly set a flag by modifying
Mangled.cpp (windows, freebsd). The Xcode build always used builtin demangler by passing a
compiler flag. This adds a cmake flag (defaulting to ON) to configure the demangling library used
at build time. The flag is only available on non-windows platforms as there the system demangler
is not present (in the form we're trying to use it, at least).
The impact of this change is:
- linux: switches to the builtin demangler
- freebsd, windows: NFC (I hope)
- netbsd: switches to the builtin demangler
- osx cmake build: switches to the builtin demangler (matching the XCode build)

The main motivation for this is the cross-platform case, where it should bring more consistency
by removing the dependency on the host demangler (which can be completely unrelated to the debug
target).

Jim Ingham 1bf7d30469 Make all the Function implementations different so the compiler won't share them.
Clang on ARM64 was making the three Function methods with identical bodies have
one implementation that was shared.  That threw off the count of breakpoints, since
we don't count as separate locations three functions with the same address.

I also cleaned up the test case while I was at it.

Pavel Labath 0faf37333c gdb-remote: Make the sequence mutex non-recursive
Summary:
This is a preparatory commit for D22914, where I'd like to replace this mutex by an R/W lock
(which is also not recursive). This required a couple of changes:
- The only caller of Read/WriteRegister, GDBRemoteRegisterContext class, was already acquiring
  the mutex, so these functions do not need to. All functions which now do not take a lock, take
  an lock argument instead, to remind the caller of this fact.
- GetThreadSuffixSupported() was being called from locked and unlocked contexts (including
  contexts where the process was running, and the call would fail if it did not have the result
  cached). I have split this into two functions, one which computes the thread suffix support and
  caches it (this one always takes the lock), and another, which returns the cached value (and
  never needs to take the lock). This feels quite natural as ProcessGdbRemote was already
  pre-caching this value at the start.

When, for instance, "step-in" steps into a function that it doesn't want

the step out so it can then continue stepping.  These step out's don't use

Pavel Labath b42b48e051 Remove the last manually constructed packet from gdb-remote register context + small refactor
Summary:
The tricky part here was that the exisiting implementation of WriteAllRegisters was expecting
hex-encoded data (as that was what the first implementation I replaced was using, but here we had
binary data to begin with. I thought the read/write register functions would be more useful if
they handled the hex-encoding themselves (all the other client functions provide the responses in
a more-or-less digested form). The read functions return a DataBuffer, so they can allocate as
much memory as they need to, while the write functions functions take an llvm::ArrayRef, as that
can be constructed from pretty much anything.

Summary:

everyone else use that. The function takes the partial packet as a StreamString rvalue reference,
to avoid a copy and to remind the users that the packet will have undeterminate contents after
the call.

This also fixes the incorrect formatting of the QRestoreRegisterState packet in case thread
suffix is not supported.

Pavel Labath 56d7262b69 Move packet construction from GDBRemoteRegisterContext go the communication class
Summary:
When saving/restoring registers the GDBRemoteRegisterContext class was manually constructing
the register save/restore packets. This creates appropriate helper functions in
GDBRemoteCommunicationClient, and switches the class to use those. It also removes what a
duplicate packet send in some of those functions, a thing that I can only attribute to a bad
merge artefact.

I also add a test framework for testing gdb-remote client functionality and add tests for the new
functions I introduced. I'd like to be able to test the register context changes in isolation as
well, but currently there doesn't seem to be a way to reasonably construct a standalone register
context object, so we'll have to rely on the end-to-end tests to verify that.

Pavel Labath 1ac2b20d25 Fix expression evaluation with operator new
Summary:
referencing a user-defined operator new was triggering an assert in clang because we were
registering the function name as string "operator new", instead of using the special operator
enum, which clang has for this purpose. Method operators already had code to handle this, and now
I extend this to cover free standing operator functions as well. Test included.

Pavel Labath 8749089c8c Fix a race in Broadcaster/Listener interaction
Summary:
The following problem was occuring:
- broadcaster B had two listeners: L1 and L2 (thread T1)
- (T1) B has started to broadcast an event, it has locked a shared_ptr to L1 (in
  ListenerIterator())
- on another thread T2 the penultimate reference to L1 was destroyed (the transient object in B is
  now the last reference)
- (T2) the last reference to L2 was destroyed as well
- (T1) B has finished broadcasting the event to L1 and destroyed the last shared_ptr
- (T1) this triggered the destructor, which called into B->RemoveListener()
- (T1) all pointers in the m_listeners list were now stale, so RemoveListener emptied the list
- (T1) Eventually control returned to the ListenerIterator() for doing broadcasting, which was
  still in the middle of iterating through the list
- (T1) Only now, it was holding onto a dangling iterator. BOOM.

I fix this issue by making sure nothing can interfere with the
iterate-and-remove-expired-pointers loop, by moving this logic into a single function, which
first locks (or clears) the whole list and then returns the list of valid and locked Listeners
for further processing. Instead of std::list I use an llvm::SmallVector which should hopefully
offset the fact that we create a copy of the list for the common case where we have only a few
listeners (no heap allocations).

A slight difference in behaviour is that now RemoveListener does not remove an element from the
list -- it only sets it's mask to 0, which means it will be removed during the next iteration of
GetListeners(). This is purely an implementation detail and it should not be externally
noticable.

I was not able to reproduce this bug reliably without inserting sleep statements into the code,
so I do not add a test for it. Instead, I add some unit tests for the functions that I do modify.

Change r278527 was filtering out too many libraries.
The Xcode lldb-gtest target depends on linking libgtest*.a,
but those were not being included.  This caused the lldb-gtest

Greg Clayton c6c420fca1 Switch over to using socketpair for local debugserver connections as they are twice as fast as TCP sockets (on macOS at least).
This change opens a socket pair and passes the second socket pair file descriptor down to the debugserver binary using a new option: "--fd=N" where N is the file descriptor. This file descriptor gets passed via posix_spawn() so that there is no need to do any bind/listen or bind/accept calls and eliminates the hanshake unix socket that is used to pass the result of the actual port that ends up being used so it can save time on launch as well as being faster.

This is currently only enabled on __APPLE__ builds. Other OSs should try modifying the #define from ProcessGDBRemote.cpp but the first person will need to port the --fd option over to lldb-server. Any OSs that enable USE_SOCKETPAIR_FOR_LOCAL_CONNECTION in their native builds can use the socket pair stuff. The #define is Apple only right now, but looks like:

#if defined (__APPLE__)
#define USE_SOCKETPAIR_FOR_LOCAL_CONNECTION 1

Pavel Labath fdb2d99eaf Fix-up r278299 for windows
FD_SETSIZE on windows limits the number of file descriptors, rather than their individual
magnitude (the underlying implementation uses an array rather than a bitset). This meant that the
assert in the SelectHelper was incorrect, and failing all the time. Fix that.

I am not sure whether this should be #ifdef MSVC, or #ifdef WINDOWS, but my feeling is that a
more posix-conforming implementation on windows would choose the bitset implementation, so I'm
sticking with the former.

A number like 0xf000000000000000L could be placed into a dictionary, and sent to LLDB and it would end up being 0xffffffffffffffff since it would overflow a int64_t. We leave the old code there, but if it overflows, we treat the number like a uint64_t and get it to decode correctly. Added a gtest to cover this so we don't regress. I verified the gtest failed prior to the fix, and it succeeds after it.

It's always hard to remember when to include this file, and
when you do include it it's hard to remember what preprocessor
check it needs to be behind, and then you further have to remember
whether it's windows.h or win32.h which you need to include.

This patch changes the name to PosixApi.h, which is more appropriately
named, and makes it independent of any preprocessor setting.

There's still the issue of people not knowing when to include this,
because there's not a well-defined set of things it exposes other
than "whatever is missing on Windows", but at least this should
make it less painful to fix when problems arise.

This patch depends on LLVM revision r278170.

Due to internal reuse of buffers in the RenderScript runtime by the system allocator,
comparing pointers is not a safe way to check whether an allocation is tracked by lldb.

Dimitar Vlahovski 023dd64f25 Add/fix support for i386 elf core files
Summary:
There were places in the code, assuming(hardcoding) offsets
and types that were only valid for the x86_64 elf core file format.

The NT_PRSTATUS and NT_PRPSINFO structures are with the 64 bit layout.
I have reused them and parse i386 files manually, and fill them in the
same struct.

Also added some error handling during parsing that checks if the
available bytes in the buffer are enough to fill the structures.

The i386 core file test case now passes.

For reference on the structures layout, I generally used the
source of binutils (bfd, readelf)

Pavel Labath e768c4b858 Rewrite gdb-remote's SendContinuePacketAndWaitForResponse
SendContinuePacketAndWaitForResponse was huge function with very complex interactions with
several other functions (SendAsyncSignal, SendInterrupt, SendPacket). This meant that making any
changes to how packet sending functions and threads interact was very difficult and error-prone.

This change does not add any functionality yet, it merely paves the way for future changes. In a
follow-up, I plan to add the ability to have multiple query packets in flight (i.e.,
request,request,response,response instead of the usual request,response sequences) and use that
to speed up qModuleInfo packet processing.

Here, I introduce two special kinds of locks: ContinueLock, which is used by the continue thread,
and Lock, which is used by everyone else. ContinueLock (atomically) sends a continue packet, and
blocks any other async threads from accessing the connection. Other threads create an instance of
the Lock object when they want to access the connection. This object, while in scope prevents the
continue from being send. Optionally, it can also interrupt the process to gain access to the
connection for async processing.

Most of the syncrhonization logic is encapsulated within these two classes. Some of it still
had to bleed over into the SendContinuePacketAndWaitForResponse, but the function is still much
more manageable than before -- partly because of most of the work is done in the ContinueLock
class, and partly because I have factored out a lot of the packet processing code separate
functions (this also makes the functionality more easily testable). Most importantly, there is
none of syncrhonization code in the async thread users -- as far as they are concerned, they just
need to declare a Lock object, and they are good to go (SendPacketAndWaitForResponse is now a
very thin wrapper around the NoLock version of the function, whereas previously it had over 100
lines of synchronization code).  This will make my follow up changes there easy.

I have written a number of unit tests for the new code and I have ran the test suite on linux and
osx with no regressions.

Abhishek Aggarwal f605c198c9 Improve code of loading plugins that provide cmnds
Summary:
 - Modified code that enables writing new user-defined commands
   and use them through LLDB CLI. Modifications are:

  -- Define the 'syntax' for each user-defined command
    --- Added an argument in SBCommandInterpreter::AddCommand()
        and SBCommand::AddCommand() API
    --- Allow passing syntax for each user-defined command
    --- Earlier, only 'help' could be defined and passed for commands

  -- Passed 'number of arguments' entered on CLI for user-defined commands
    --- Added an argument (number of options) in SBCommandPluginInterface::DoExecute()
        API to know the number of arguments passed for commands

  -- In CommandPluginInterfaceImplementation class:
    --- Make the data member m_backend a shared_ptr
    --- Avoids memory leaks of dynamically allocated SBCommandPluginInterface instances
        created in lldb::PluginInitialize() API

Jason Molenda 8129255e76 PlatformDarwinKernel maintains a list of kexts and kernels
that it finds on the local computer in "well known" locations
when we start up the darwin-kernel platform.  It did not 
distinguish between kexts/kernels with dSYMs from others -
when it needed a kernel/kext with a given UUID, it would grab
the first one it finds.

This change separates these into two vectors -- a collection
of kexts and kernels with dSYMs next t othem, and a collection
of kexts and kernels without dSYMs.  When we have a bundle ID
and uuid to search for, we first try the collections with
dSYMs, and if that fails, then we try the collections that
did not have dSYMs next to them.

Often times we'll have a situation where a kext will be 
installed in multiple locations on a system, but only one
of them will have a dSYM next to it, where the dev just copied
it to a local directory.  This fixes that problem, giving
precedence to those binaries with debug information.

Jason Molenda 13becd4f43 Move the code which knows how to get information about the shared
cache from ObjectFileMachO (very wrong place) to the DynamicLoader
plugins (better place).  Not much change to the code itself, although
the old ObjectFileMachO method would try both the new dyld SPI and
reading the dyld_all_image_infos structure.  In the new methods,
I've separated those into the appropriate DynamicLoader plugins.

Saleem Abdulrasool 2d6a9ec935 Clean up vestigial remnants of locking primitives
This finally removes the use of the Mutex and Condition classes. This is an
intricate patch as the Mutex and Condition classes were tied together.
Furthermore, many places had slightly differing uses of time values. Convert
timeout values to relative everywhere to permit the use of
std::chrono::duration, which is required for the use of
std::condition_variable's timeout. Adjust all Condition and related Mutex
classes over to std::{,recursive_}mutex and std::condition_variable.

This change primarily comes at the cost of breaking the TracingMutex which was
based around the Mutex class. It would be possible to write a wrapper to
provide similar functionality, but that is beyond the scope of this change.
