Greg Clayton 1b65488229 Added code that will allow completely customizable prompts for use in
replacing the "(lldb)" prompt, the "frame #1..." displays when doing
stack backtracing and the "thread #1....". This will allow you to see 
exactly the information that you want to see where you want to see it.
This currently isn't hookup up to the prompts yet, but it will be soon.

So what is the format of the prompts? Prompts can contain variables that
have access to the current program state. Variables are text that appears
in between a prefix of "${" and ends with a "}". Some of the interesting
variables include:

// The frame index (0, 1, 2, 3...)
${frame.index}

// common frame registers with generic names
${frame.pc}
${frame.sp}
${frame.fp}
${frame.ra}
${frame.flags}

// Access to any frame registers by name where REGNAME is any register name:
${frame.reg.REGNAME}

// The current compile unit file where the frame is located
${file.basename}
${file.fullpath}

// Function information
${function.name}
${function.pc-offset}

// Process info
${process.file.basename}
${process.file.fullpath}
${process.id}
${process.name}

// Thread info
${thread.id}
${thread.index}
${thread.name}
${thread.queue}
${thread.stop-reason}

// Target information
${target.arch}

// The current module for the current frame (the shared library or executable
// that contains the current frame PC value):
${module.file.basename}
${module.file.fullpath}

// Access to the line entry for where the current frame is when your thread
// is stopped:
${line.file.basename}
${line.file.fullpath}
${line.number}
${line.start-addr}
${line.end-addr}

Many times the information that you might have in your prompt might not be
available and you won't want it to print out if it isn't valid. To take care
of this you can enclose everything that must resolve into a scope. A scope
is starts with '{' and ends with '}'. For example in order to only display
the current file and line number when the information is available the format
would be:

"{ at {$line.file.basename}:${line.number}}"

Broken down this is:

start the scope: "{"

format whose content will only be displayed if all information is available:
        "at {$line.file.basename}:${line.number}"

end the scope: "}"

We currently can represent the infomration we see when stopped at a frame:

frame #0: 0x0000000100000e85 a.out`main + 4 at test.c:19

with the following format:

"frame #${frame.index}: ${frame.pc} {${module.file.basename}`}{${function.name}{${function.pc-offset}}{ at ${line.file.basename}:${line.number}}\n"

This breaks down to always print:

        "frame #${frame.index}: ${frame.pc} "

only print the module followed by a tick if we have a valid module:

        "{${module.file.basename}`}"
        
print the function name with optional offset:
        "{${function.name}{${function.pc-offset}}"

print the line info if it is available:
        
        "{ at ${line.file.basename}:${line.number}}"

then finish off with a newline:

        "\n"

Notice you can also put newlines ("\n") and tabs and everything else you
are used to putting in a format string when desensitized with the \ character.

Cleaned up some of the user settings controller subclasses. All of them 
do not have any global settings variables and were all implementing stubs
for the get/set global settings variable. Now there is a default version
in UserSettingsController that will do nothing.

Greg Clayton ed8a705cea General command line help cleanup:
- All single character options will now be printed together
- Changed all options that contains underscores to contain '-' instead
- Made the help come out a little flatter by showing the long and short
  option on the same line.
- Modified the short character for "--ignore-count" options to "-i"

Greg Clayton 6ba7815115 Bug #: 8447030
Fixed an issue with ClangASTContext::GetIndexOfChildMemberWithName() 
where objective C ivars were not being found correctly if they were
the second or higher child.

Greg Clayton a701509229 Fixed the way set/show variables were being accessed to being natively
accessed by the objects that own the settings. The previous approach wasn't
very usable and made for a lot of unnecessary code just to access variables
that were already owned by the objects.

While I fixed those things, I saw that CommandObject objects should really
have a reference to their command interpreter so they can access the terminal
with if they want to output usaage. Fixed up all CommandObjects to take
an interpreter and cleaned up the API to not need the interpreter to be
passed in.

Fixed the disassemble command to output the usage if no options are passed
down and arguments are passed (all disassebmle variants take options, there
are no "args only").

Johnny Chen 49b415de1f Added a hook for the test driver to take an optional config file to customize
the running of the test suite.  Right now, it doesn't do anything with the
config file.

Pass "-c myConfigFile" to specify the config file.

Johnny Chen b330786d1f Added test cases to FoundationTestCase to exercise lookup of objc data types and
to evaluate expressions.  Marked with @expectedFailure decorators for the time
being.

Enhanced the lldbtest.TestBase.expect() API to allow an additional keyword arg
named "error".  If the client passes "error=True", it signifies that an error
while running the command is expected.  The golden input is then compared
against the return object's error output.

Johnny Chen 2756d60563 Added extra test scenarios to break on a selector with:

llvm-svn: 114124
2010-09-16 22:32:47 +00:00

2010-09-16 17:37:05 +00:00
Johnny Chen df80a4cf25 Cleaned up the option processing logic and added a '-i' option to ignore the
build tree relative search path in order to locate the lldb.py module.  When
'-i' is present, the test driver relies on the PYTHONPATH environment variable
to locate the lldb.py module.

llvm-svn: 114087
2010-09-16 16:23:16 +00:00
Benjamin Kramer b12ec91a3d Make this method static. Bad things(tm) happen when a non-static method is called in a constructor's initializer list.

Benjamin Kramer 7309e6c7f1 Unbreak build, you can't take a pointer from a "register" variable. Most compilers ignore this keyword anyways.
Also remove a typedef that typedefs nothing.

llvm-svn: 114081
2010-09-16 15:44:23 +00:00
Johnny Chen 1a9f4dd5a0 Provided a mechanism for the test class to cleanup after itself once it's done.
This will remove the confusion experienced when previous test runs left some
files (both intermediate or by-product as a result of the test).

lldbtest.TestBase defines a classmethod tearDownClass(cls) which invokes the
platform-specific cleanup() function as defined by the plugin; after that, it
invokes a subclass-specific function classCleanup(cls) if defined; and, finally,
it restores the old working directory.

An example of classCleanup(cls) is in settings/TestSettings.py:

    @classmethod
    def classCleanup(cls):
        system(["/bin/sh", "-c", "rm output.txt"])

where it deletes the by-product "output.txt" as a result of running a.out.

2010-09-16 00:58:09 +00:00
Jim Ingham 0909e5f4df Add the ability to not resolve the name passed to FileSpec. Then don't resolve the names of compilation units found in DWARF.

2010-09-15 22:48:40 +00:00
Johnny Chen d5e111c2c1 Added two test cases to TestSettings.py which exercise the lldb's:
(lldb) settings set process.run-args A B C
(lldb) settings set process.env-vars ["MY_ENV_VAR"]=YES

commands.  The main.cpp checks whether A, B, C is passed to main and whether
the $MY_ENV_VAR env variable is defined and outputs the findings to a file.

llvm-svn: 114031
2010-09-15 22:27:29 +00:00
Caroline Tice 3f12e8efc1 Remove unnecessary/inappropriate output-printing functions from
the API.

llvm-svn: 113993
2010-09-15 18:29:06 +00:00
Johnny Chen 73982b94e3 Also added BuildAndIntegration to the directories to search for an existing
lldb.py module.  The priorities to search for are Debug, Release, then
BuildAndIntegration.  You can always override this with a valid PYTHONPATH
environment variable before running the test driver.

For example:

$ PYTHONPATH=/Find/My/LLDB/Module/Here ./dotest.py -v .

Python runtime will try to locate the lldb.py module from
/Find/My/LLDB/Module/Here first before trying the Debug, Release, and then
BuildAndIntegration directories.

Johnny Chen f7f0cabe9f We believed the intermittent process launch failure while running the test suite

2010-09-15 17:33:57 +00:00
Johnny Chen bce48fb06f Removed the @expectedFailure decorator for test_with_dwarf() test case. It has

Greg Clayton d88d759a74 15-20% speed improvement when parsing DWARF. I used instruments to
find the hotspots in our code when indexing the DWARF. A combination of
using SmallVector to avoid collection allocations, using fixed form
sizes when possible, and optimizing the hot loops contributed to the
speedup.

llvm-svn: 113961
2010-09-15 08:33:30 +00:00
Caroline Tice 7d9edf670b Modify "settings list" so you can specify a particular instance setting name,
or a settings prefix, and it will list information about the subset of settings
you requested.  Also added tab-completion (now that it takes an optional argument).

llvm-svn: 113952
2010-09-15 06:56:39 +00:00
Greg Clayton 6dbd39838d Fixed a missing newline when dumping mixed disassembly.
Added a "bool show_fullpaths" to many more objects that were
previously always dumping full paths.

Fixed a few places where the DWARF was not indexed when we
we needed it to be when making queries. Also fixed an issue
where the DWARF in .o files wasn't searching all .o files
for the types.

Fixed an issue with the output from "image lookup --type <TYPENAME>"
where the name and byte size might not be resolved and might not
display. We now call the accessors so we end up seeing all of the
type info.

Caroline Tice ded2fa3991 Remove all visible uses of "[DEFAULT]" instance name.

2010-09-15 05:35:14 +00:00
Greg Clayton 86c3f345c6 Fixed a race condition that was sometimes stopping our command line
interpreter from working. The communication read thread could
startup and immediately exit if m_read_thread_enabled was
checked in the thread function before it was set by the
thread that spawns the read thread. Now m_read_thread_enabled is set
to true prior to spawning the read thread to avoid this issue.

Hopefully this will clear up the sporatic failures in our test suite.

2010-09-15 05:19:45 +00:00
Greg Clayton c685f8e540 So we can't use .debug_pubtypes as it, as designed, does not tell us about
all types in all compile units. I added a new kind of accelerator table to
the DWARF that allows us to index the DWARF compile units and DIEs in a way
that doesn't require the data to stay loaded. Currently when indexing the
DWARF we check if the compile unit had parsed its DIEs and if it hasn't we
index the data and free all of the DIEs so we can reparse later when we need
to after using one of our complete accelerator tables to determine we need
to reparse some DWARF. If the DIEs had already been parsed we leave them 
loaded. The new accelerator table uses the "const char *" pointers from our
ConstString class as the keys, and NameToDIE::Info as the value. This info
contains the compile unit index and the DIE index which means we are pointed
right to the DIE we need unlike the other DWARF accelerator tables that often
just point us to the compile unit we would find our answer in.
