Summary:
this also gets rid of a compiler warning in release builds by using a dynamically allocated
buffer. Therefore, a size assertion is not necessary (and probably should have been an error in
the first place).

When launching argdumper, there are a few problems with the
current logic. First, on Windows, the file is called
argdumper.exe, not argdumper. Second, Windows paths have
backslashes in them, and JSON treats <backslash><char> as an
escape sequence. To fix the second problem, on Windows we
convert backslashes to forward slashes, since backslash isn't
a valid filename character anyway this shouldn't be a problem.

llvm::StringRef doesn't make a copy of a string, it just holds a
reference. When special_directions_stream went out of scope,
special_directions was holding on to a stale pointer.

special_directions pointing to a valid string.

CopyContext is necessary to safely get the XState, but LLDB doesn't currently
use the XState. CopyContext is available as of Windows 7 SP1, so it can't be
used on Vista. Furthermore, it requires the Windows 8 SDK it compile,
making the baseline for compiling and running LLDB higher than necessary.

Previously we would create the extension module as a post-build
step of creating liblldb. As part of this process, we created
symlinks and did other stuff.
This had several longstanding issues related to target
dependencies, such as not re-creating the symlink if liblldb.dll
failed to link, or if the build was Ctrl+C'ed from.
Then, the script that creates the symlinks began to grow to
include other things, such as argdumper, and it would try to
create symlinks before it had finished building the targets it
needed to symlink to.
This patches addresses all of these problems by creating an
explicit target for the script to run, and making it have a
dependency on all the targets it needs to create symlinks from/to.

Summary:
Currently we have some settings which treat "\ " on settings set commands specially. E.g., it is
a valid way of specifying an argument of " " to a target. However, this fails if "\ " is the last
argument as CommandObjectSettingsSet strips trailing whitespace. This resulted in a surprising
argument of "\" to the target.
This patch disables the training whitespace removal at a global
level. Instead, for each argument type we locally determine whether whitespace stripping makes
sense. Currently, I strip whitespace for all simple object type except of regex and
format-string, with the rationale that these two object types do their own complex parsing and we
want to interfere with them as least as possible. Specifically, stripping the whitespace of a
regex "\ " will result in a (surprising?) error "trailing backslash". Furthermore, the default
value of dissasembly-format setting already contains a trailing space and there is no way for the
user to type this in manually if we strip whitespace.

GetVariableInfo () collected the values of the variable in a list. But it also
tried to generate the name/value pairs for children. This caused generation of
a wrong value string for may items. This function has been fixed to put value in
the list only.
The handling of --print-value related option has been moved to caller.
GetVariableInfo2 and MIResponseFormVariableInfo3 have been removed. They were
almost the duplicate of functions of similar names. I dont see any difference in
the output of -stack-list-locals and -stack-list-arguments. So these functions
just seemed unnecessary.
Char variable was being printed as a string which caused garbage output. This has

There was a test in the test suite that was triggering the backtrace logging output that requested that the client pass an execution context. Sometimes we need the process for Objective C types because our static notion of the type might not align with the reality when being run in a live runtime.

llvm-svn: 228892
Rules for returning "const char *" from functions in the public lldb::SB* API are that you must constify the string using "ConstString(cstr).GetCString()" and return that. This puts the string into a string pool that never goes away. This is only when there is nothing that can hold onto the string. It is OK to specify that a string value lives as long as its SB class counterpart, but this should be made clear in the API if this is done. Many classes already constify their strings (symbol mangled and demangled names, variable names, type names, etc), so be sure to verify you string isn't already constified before you re-constify it. It won't do any harm to re-constify it, it will just cause you a little performance by having to rehash the string.
llvm-svn: 228867
This removes the rule from the LLDB coding standard about putting

A runtime support value is a ValueObject whose only purpose is to support some language runtime's operation, but it does not directly provide any user-visible benefit
As such, unless the user is working on the runtime support, it is mostly safe for them not to see such a value when debugging
It is a language runtime's job to check whether a ValueObject is a support value, and that - in conjunction with a target setting - is used by frame variable and target variable
SBFrame::GetVariables gets a new overload with yet another flag to dictate whether to return those support values to the caller - that which defaults to the setting's value

Because types are not reliably protected against the death of their owners, having ValueObjects lurking around like that past the useful lifetime of their owner processes is a potential source of crashes

llvm-svn: 228393
Summary:
After closing all the leaked file descriptors to the inferior tty, the following problem occured:
- when stdin, stdout and stderr are redirected, there are no slave descriptors open (which is good)
- lldb has a reader thread, which attempts to read from the master end of the tty
- this thread receives an EOF
- in response, it closes it's master end
- as this is the last open file descriptor for the master end, this deletes the tty and sends
SIGHUP to the inferior (this is bad)
I fix this problem by making sure the master end remains open for the duration of the inferior
process by storing a copy of the file descriptor in ProcessMonitor. I create a copy to avoid
ownership issues with the reading thread.

Summary:
Mac-only tests were leaving .d.$$$$ dependency files left in the test tree. This happened
because:
1) "make clean" was invoked although no tests in the folder were run
2) The Makefile had main.d as a dependency, which meant it tried to compile the source file (to extract
dependencies).
3) The compile failed (does not compile on linux) and left behind a main.d.$$$$ temporary file.
4) "make clean" tried to clean up these temporary files, but the expansion $(wildcard *.d.[0-9]*)
was performed before the temporary file was created, so this file was not caught.
I fix this by giving all the temporary files deterministic names, which makes it easier to clean
them up afterwards. I also make the rules for generating the dependency files more robust and
less likely to leak files in the first place.

Background: dyld binaries often have extra symbols in their symbol table like "malloc" and "free" for the early bringup of dyld and we often don't want to set breakpoints in dynamic linker binaries. We also don't want to call the "malloc" or "free" function in dyld when a user writes an expression like "(void *)malloc(123)" so we need to avoid doing name lookups in dyld. We mark Modules as being dynamic link editors and this helps do correct lookups for breakpoints by name and function lookups.

Why? Debugger::FormatPrompt() would run through the format prompt every time and parse it and emit it piece by piece. It also did formatting differently depending on which key/value pair it was parsing.
The new code improves on this with the following features:
1 - Allow format strings to be parsed into a FormatEntity::Entry which can contain multiple child FormatEntity::Entry objects. This FormatEntity::Entry is a parsed version of what was previously always done in Debugger::FormatPrompt() so it is more efficient to emit formatted strings using the new parsed FormatEntity::Entry.
2 - Allows errors in format strings to be shown immediately when setting the settings (frame-format, thread-format, disassembly-format
3 - Allows auto completion by implementing a new OptionValueFormatEntity and switching frame-format, thread-format, and disassembly-format settings over to using it.
4 - The FormatEntity::Entry for each of the frame-format, thread-format, disassembly-format settings only replaces the old one if the format parses correctly
5 - Combines all consecutive string values together for efficient output. This means all "${ansi.*}" keys and all desensitized characters like "\n" "\t" "\0721" "\x23" will get combined with their previous strings
6 - ${*.script:} (like "${var.script:mymodule.my_var_function}") have all been switched over to use ${script.*:} "${script.var:mymodule.my_var_function}") to make the format easier to parse as I don't believe anyone was using these format string power user features.
7 - All key values pairs are defined in simple C arrays of entries so it is much easier to add new entries.
These changes pave the way for subsequent modifications where we can modify formats to do more (like control the width of value strings can do more and add more functionality more easily like string formatting to control the width, printf formats and more).

Summary:
Both LLDB and LLGS are leaking file descriptors into the debugged process. This plugs the leak by
closing the unneeded descriptors. In one case I use O_CLOEXEC, which I hope is supported on
relevant platforms. I also added a regression test and plugged a fd leak in dosep.py.

lldb-mi has 3 threads.
1. One that waits for user intput.
2. Another waits for 1st thread to get input command.
3. Waits for events from lldb.
2 & 3 needs to be synchronized so that they don't end up
doing things at same time. For example, while "break insert" is
processing, we can get a breakpoint event. Depending on where we
are in "break-insert", it can have different behavior. In some
cases, it can cause breakpoint to be deleted too. I have added a
mutex so that command processing and event processing are done
exclusively and they are not running at the same time.
In longer term, I think thread 2 & 3 should be merged to be only
one thread which can wait on command or events.

In that case, we want to copy the entire file into memory. The code was looking for
a default byte size of 0 to indicate that the user had not provided a specific # of
bytes to copy; adjust that to 1 to match the actual default value.

Summary:
The Android dynamic linker reports only the basename of each SO entry, so for
the above check to be successful, we need to compare it to the basename of the
main executable.
This also has a nasty side-effect when working with older version of
Android (verified on platform version 16), and debugging PIE
executables: the dynamic linker has a bug and reports the load address
of the main executable (which is a shared object, because PIE) to be 0.
We then try to update the list of loaded sections for all shared
objects, including the main executable, and set the load address to 0,
which breaks everything that relies on resolving addresses in the main
executable (breakpoints, stepping, etc). This commit also fixes that broken
behavior when debugging on older Androids. This bug doesn't happen on newer
Android versions (verified for Android L).
Test Plan: Run test suite on linux.

On windows, signal handler is reset to default once a signal is received.
This causes doing ctrl-c twice on console (or pressing suspend button twice
in eclipse ide which uses SIGINT to stop the debuggee) to crash lldb-mi on
windows. Although there is very tiny window (after signal handler is called
and before we restore the handler) where default handler will be in place.
But this is hardly a problem in practice as IDEs generally disable their suspend
button once it has been presses.

This patch fixes execution of CLI commands in MI mode. The CLI commands are
executed using "-interpreter-exec" command. The bug was in the
CMICmnLLDBDebugSessionInfo class which contained the following members:
SBProcess, SBTarget, SBDebugger and SBListener, but CLI commands don't affect
them and they aren't updated. Therefore some members can contain incorrect
(or obsolete) reference and it can cause an error. My patch removes these
members and uses getters that provides the updated instance every time it is used.
