a shell would interpret it. A few examples that we now handle correctly
INPUT: "Hello "world
OUTPUT: "Hello World"
INPUT: "Hello "' World'
OUTPUT: "Hello World"
INPUT: Hello" World"
OUTPUT: "Hello World"
This broke the setting of dictionary values for the "settings set" command
for things like:
(lldb) settings set target.process.env-vars ["MY_ENV_VAR"]=YES
since we would drop the quotes. I fixed the user settings controller to use
a regular expression so it can accept any of the following inputs for
dictionary setting:
settings set target.process.env-vars ["MY_ENV_VAR"]=YES
settings set target.process.env-vars [MY_ENV_VAR]=YES
settings set target.process.env-vars MY_ENV_VAR=YES
We might want to eventually drop the first two syntaxes, but I won't make
that decision right now.
This allows more natural setting of the envirorment variables:
settings set target.process.env-vars MY_ENV_VAR=YES ABC=DEF CWD=/tmp

Extend Swig's include search path.
Cover both /usr/include and /usr/local/include. This should allow Swig to find
system headers such as stdint.h on all platforms we currently support.

- Make sure cmd_obj & cmd_obj_sp contain a valid objects before attempting to
dereference, in CommandObjectCommandsAlias::Execute and
CommandInterpreter::HandleCommand.
- Modify CommandInterpreter::GetCommandSPExact to properly handle
multi-word command inputs.
llvm-svn: 121779
- Added new utility function to Arg, GetQuotedCommandString, which re-assembles
the args into a string, replacing quotes that were originally there.
- Modified user settings stuff to always show individual elements when printing out
arrays and dictionaries.
- Added more extensive help to 'settings set', explaining more about dictionaries
and arrays (including current dictionary syntax).
- Fixed bug in user settings where quotes were being stripped and lost, so that
sometimes array or dictionary elements that ought to have been a single element
were being split up.

not the command should take raw input, then handle & dispatch the arguments appropriately.
Also change the 'alias' command to be a command that takes raw input. This is necessary to
allow aliases to be created for other commands that take raw input and might want to include
raw input in the alias itself.
Fix a bug in the aliasing mechanism when creating aliases for commands with 3-or-more words.
Raw input should now be properly handled by all the command and alias mechanisms.
llvm-svn: 121423
- Add logging for command resolution ('log enable lldb commands')
- Fix alias resolution to properly handle commands that take raw input (resolve the alias, but
don't muck up the raw arguments).
Net result: Among other things, 'expr' command can now take strings with escaped characters and
not have the command handling & alias resolution code muck up the escaped characters. E.g.
'expr printf ("\n\n\tHello there!")' should now work properly.
Not working yet: Creating aliases with raw input for commands that take raw input. Working on that.
e.g. 'command alias print_hi expr printf ("\n\tHi!")' does not work yet.

comes from by using a virtual function to provide it from the Module's
SymbolVendor by default. This allows the DWARF parser, when being used to
parse DWARF in .o files with a parent DWARF + debug map parser, to get its
type list from the DWARF + debug map parser so when we go and find full
definitions for types (that might come from other .o files), we can use the
type list from the debug map parser. Otherwise we ended up mixing clang types
from one .o file (say a const pointer to a forward declaration "class A") with
the a full type from another .o file. This causes expression parsing, when
copying the clang types from those parsed by the DWARF parser into the
expression AST, to fail -- for good reason. Now all types are created in the
same list.
Also added host support for crash description strings that can be set before
doing a piece of work. On MacOSX, this ties in with CrashReporter support
that allows a string to be dispalyed when the app crashes and allows
LLDB.framework to print a description string in the crash log. Right now this
is hookup up the the CommandInterpreter::HandleCommand() where each command
notes that it is about to be executed, so if we crash while trying to do this
command, we should be able to see the command that caused LLDB to exit. For
all other platforms, this is a nop.

version); change include statements to use Python.h in the Python framework

all of the calls inlined in the header file for better performance.
Fixed the summary for C string types (array of chars (with any combo if
modifiers), and pointers to chars) work in all cases.
Fixed an issue where a forward declaration to a clang type could cause itself
to resolve itself more than once if, during the resolving of the type itself
it caused something to try and resolve itself again. We now remove the clang
type from the forward declaration map in the DWARF parser when we start to
resolve it and avoid this additional call. This should stop any duplicate
members from appearing and throwing all the alignment of structs, unions and
classes.

it logs the function calls, their arguments and the return values. This is not
complete or polished, but I am committing it now, at the request of someone who
really wants to use it, even though it's not really done. It currently does not
attempt to log all the functions, just the most important ones. I will be
making further adjustments to the API logging code over the next few days/weeks.
(Suggestions for improvements are welcome).
Update the Python build scripts to re-build the swig C++ file whenever
the python-extensions.swig file is modified.
Correct the help for 'log enable' command (give it the correct number & type of
arguments).

So the issue here was that we have lldb_private::FileSpec that by default was
always resolving a path when using the:
FileSpec::FileSpec (const char *path);
and in the:
void FileSpec::SetFile(const char *pathname, bool resolve = true);
This isn't what we want in many many cases. One example is you have "/tmp" on
your file system which is really "/private/tmp". You compile code in that
directory and end up with debug info that mentions "/tmp/file.c". Then you
type:
(lldb) breakpoint set --file file.c --line 5
If your current working directory is "/tmp", then "file.c" would be turned
into "/private/tmp/file.c" which won't match anything in the debug info.
Also, it should have been just a FileSpec with no directory and a filename
of "file.c" which could (and should) potentially match any instances of "file.c"
in the debug info.
So I removed the constructor that just takes a path:
FileSpec::FileSpec (const char *path); // REMOVED
You must now use the other constructor that has a "bool resolve" parameter that you must always supply:
FileSpec::FileSpec (const char *path, bool resolve);
I also removed the default parameter to SetFile():
void FileSpec::SetFile(const char *pathname, bool resolve);
And fixed all of the code to use the right settings.

static bool
Host::GetLLDBPath (lldb::PathType path_type, FileSpec &file_spec);
This will fill in "file_spec" with an appropriate path that is appropriate
for the current Host OS. MacOSX will return paths within the LLDB.framework,
and other unixes will return the paths they want. The current PathType
enums are:
typedef enum PathType
{
ePathTypeLLDBShlibDir, // The directory where the lldb.so (unix) or LLDB mach-o file in LLDB.framework (MacOSX) exists
ePathTypeSupportExecutableDir, // Find LLDB support executable directory (debugserver, etc)
ePathTypeHeaderDir, // Find LLDB header file directory
ePathTypePythonDir // Find Python modules (PYTHONPATH) directory
} PathType;
All places that were finding executables are and python paths are now updated
to use this Host call.
Added another new host call to launch the inferior in a terminal. This ability
will be very host specific and doesn't need to be supported on all systems.
MacOSX currently will create a new .command file and tell Terminal.app to open
the .command file. It also uses the new "darwin-debug" app which is a small
app that uses posix to exec (no fork) and stop at the entry point of the
program. The GDB remote plug-in is almost able launch a process and attach to
it, it currently will spawn the process, but it won't attach to it just yet.
This will let LLDB not have to share the terminal with another process and a
new terminal window will pop up when you launch. This won't get hooked up
until we work out all of the kinks. The new Host function is:
static lldb::pid_t
Host::LaunchInNewTerminal (
const char **argv, // argv[0] is executable
const char **envp,
const ArchSpec *arch_spec,
bool stop_at_entry,
bool disable_aslr);
Cleaned up FileSpec::GetPath to not use strncpy() as it was always zero
filling the entire path buffer.
Fixed an issue with the dynamic checker function where I missed a '$' prefix
that should have been added.

and 'process handle'. The test suite would like to control the asynch/sync
execution of the interpreter during the middle of the test method, so the
CommandInterpreter::SetSynchronous(bool value) is modified to allow the mode to
be changed more than once.
In practice, it would be advisable to control the process and to set the
async/sync mode from a single thread, too.
llvm-svn: 116467
Add missing break statment to case statement in Process::ShouldBroadcastEvent.
Add new command, "process handle" to allow users to control process behavior on
the receipt of various Unix signals (whether the process should stop; whether the
process should be passed the signal; whether the debugger user should be notified
that the signal came in).

arguments are specified in a standardized way, will have a standardized name, and

The next step is to start writing useful help for all the argument types.
llvm-svn: 115335
command options; makes it easier to ensure that the same type of
argument will have the same name everywhere, hooks up help for command
arguments, so that users can ask for help when they are confused about
what an argument should be; puts in the beginnings of the ability to
do tab-completion for certain types of arguments, allows automatic
syntax help generation for commands with arguments, and adds command
arguments into command options help correctly.
Currently only the breakpoint-id and breakpoint-id-range arguments, in
the breakpoint commands, have been hooked up to use the new mechanism.
The next steps will be to fix the command options arguments to use
this mechanism, and to fix the rest of the regular command arguments
to use this mechanism. Most of the help text is currently missing or
dummy text; this will need to be filled in, and the existing argument
help text will need to be cleaned up a bit (it was thrown in quickly,
mostly for testing purposes).
Help command now works for all argument types, although the help may not
be very helpful yet.
Those commands that take "raw" command strings now indicate it in their
help text.
