We now spawn a thread to accept a unix socket connection from the inferior
when it spawns in the terminal, then we launch the process, then we get
the pid back through the unix socket, and then wait for it to SIGSTOP.
darwin-debug now clears the terminal screen and prints out the program and
arguments that are about to be launched.
llvm-svn: 116841
sockets so the driver doesn't just crash.
Added support for connecting to named sockets (unix IPC sockets) in
ConnectionFileDescriptor.
Modified the Host::LaunchInNewTerminal() for MacOSX to return the process
ID of the inferior process instead of the process ID of the Terminal.app. This
was done by modifying the "darwin-debug" executable to connect to lldb through
a named unix socket which is passed down as an argument. This allows a quick
handshake between "lldb" and "darwin-debug" so we can get the process ID
of the inferior and then attach by process ID and avoid attaching to the
inferior by process name since there could be more than one process with
that name. This still has possible race conditions, those will be fixed
in the near future. This fixes the SIGPIPE issues that were sometimes being
seen when task_for_pid was failing.
llvm-svn: 116792
now goes into a timestamp-specific directory instead of the previous .session-*
files.

Also, the dumping happens when a test errored in additioned to when it failed.

but something is still killing our inferior.
Fixed an issue with darwin-debug where it wasn't passing all needed arguments
to the inferior.
Fixed a race condition with the attach to named process code.
llvm-svn: 116697
"vAttachName;<PROCNAME>" packet, and wait for a new process by name to launch
with the "vAttachWait;<PROCNAME>".
Fixed a few issues with attaching where if DoAttach() returned no error, yet
there was no valid process ID, we would deadlock waiting for an event that
would never happen.
Added a new "process launch" option "--tty" that will launch the process
in a new terminal if the Host layer supports the "Host::LaunchInNewTerminal(...)"
function. This currently works on MacOSX and will allow the debugging of
terminal applications that do complex operations with the terminal.
Cleaned up the output when the process resumes, stops and halts to be
consistent with the output format.
llvm-svn: 116693
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 '$' prefix
that should have been added.
llvm-svn: 116690
suspended, we would call "int ::task_resume (task_t task);" as many times as
it took to resume the task which isn't what we want to do.
llvm-svn: 116674
pass in a 'sender' arg to the buildDefault(), buildDsym(), buildDwarf(), and
cleanup() functions. The sender arg will be the test instance itself (i.e.,
an instance of TestBase). This is so that the relevant command execution can be
recorded in the TestBase.session object if sender is available.
The lldbtest.system() command has been modified to pop the 'sender' arg out of
the keyword arguments dictionary and use it as the test instance to facilitate
seesion recordings. An example is in test/types/AbstractBase.py:
def generic_type_tester(self, atoms, quotedDisplay=False):
"""Test that variables with basic types are displayed correctly."""
# First, capture the golden output emitted by the oracle, i.e., the
# series of printf statements.
go = system("./a.out", sender=self)
There are cases when sender is None. This is the case when the @classmethod is
involved in the use of these APIs. When this happens, there is no recording
into a session object, but printing on the sys.stderr is still honored if the
trace flag is ON.
An example is in test/settings/TestSettings.py:
@classmethod
def classCleanup(cls):
system(["/bin/sh", "-c", "rm -f output.txt"])
system(["/bin/sh", "-c", "rm -f stdout.txt"])
llvm-svn: 116648
Changed all of our synthesized "___clang" functions, types and variables
that get used in expressions over to have a prefix of "$_lldb". Now when we
do name lookups we can easily switch off of the first '$' character to know
if we should look through only our internal (when first char is '$') stuff,
or when we should look through program variables, functions and types.
Converted all of the clang expression code over to using "const ConstString&"
values for names instead of "const char *" since there were many places that
were converting the "const char *" names into ConstString names and them
throwing them away. We now avoid making a lot of ConstString conversions and
benefit from the quick comparisons in a few extra spots.
Converted a lot of code from LLVM coding conventions into LLDB coding
conventions.
llvm-svn: 116634
'breakpoint delete 1' from 'breakpoint delete'. With 'breakpoint delete', the
command interpreter was asking for a confirmation from the user, which there
isn't any.
llvm-svn: 116610
breakpoint modify -c 'val == 3' 1
after:
breakpoint set -n c
which sets a breakpoint on function 'c'. The breakpoint should only stop if
expression 'val == 3' evaluates to true.
llvm-svn: 116607
since we can't parse DW_TAG_namespace DIEs as types. They are only decls in
clang. All of the types we handle right now have both clang "XXXType" classes
to go with the "XXXDecl" classes which means they can be used within the
lldb_private::Type class. I need to check to see which other decls that don't
have associated type objects need to float around the debugger and possibly
make a lldb_private::Decl class to manage them.
llvm-svn: 116558
session info after a test case failure, allowing more direct inspection of
debugger session which leads to the test failure.
For a simple usage scenario:

The test case which failed will have its recorded session info dumped to a
.session-* file in the current working directory. For test suite using
relocated directory, expect to find the .session-* files there.
In this checkin, I also add @skip decorator to the two test methods in
test/foundation/TestObjCMethods.py as it looks like the test suite is
deadlocking when running the tests. More investigations are needed.
llvm-svn: 116552
debug information and you evaluated an expression, a crash would occur as a
result of an unchecked pointer.
Added the ability to get the expression path for a ValueObject. For a rectangle
point child "x" the expression path would be something like: "rect.top_left.x".
This will allow GUI and command lines to get ahold of the expression path for
a value object without having to explicitly know about the hierarchy. This
means the ValueObject base class now has a "ValueObject *m_parent;" member.
All ValueObject subclasses now correctly track their lineage and are able
to provide value expression paths as well.
Added a new "--flat" option to the "frame variable" to allow for flat variable
output. An example of the current and new outputs:
(lldb) frame variable
argc = 1
argv = 0x00007fff5fbffe80
pt = {
x = 2
y = 3
}
rect = {
bottom_left = {
x = 1
y = 2
}
top_right = {
x = 3
y = 4
}
}
(lldb) frame variable --flat
argc = 1
argv = 0x00007fff5fbffe80
pt.x = 2
pt.y = 3
rect.bottom_left.x = 1
rect.bottom_left.y = 2
rect.top_right.x = 3
rect.top_right.y = 4
As you can see when there is a lot of hierarchy it can help flatten things out.
Also if you want to use a member in an expression, you can copy the text from
the "--flat" output and not have to piece it together manually. This can help
when you want to use parts of the STL in expressions:
(lldb) frame variable --flat
argc = 1
argv = 0x00007fff5fbffea8
hello_world._M_dataplus._M_p = 0x0000000000000000
(lldb) expr hello_world._M_dataplus._M_p[0] == '\0'
llvm-svn: 116532
if no update commands are specified it just lists the current values, and show that
it always shows the new values for a signal after it has been updated. Also updated
the help text to match the new functionality.
llvm-svn: 116520
Inside the lldb module, there's no need (and as a matter of fact, incorrect) to specify the 'lldb'
module name.
Comment out the call to lldb.SBDebugger.Initialize() within the test driver itself, since it is
already done when we import the lldb.py module.
llvm-svn: 116485
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).
llvm-svn: 116430
artifical members (like the vtable pointer member that shows up in the DWARF).
We were adding this to each class which was making all member variables be off
by a pointer size.
Added a test case so we can track this with "test/forward".
Fixed the type name index in DWARF to include all the types after finding
some types were being omitted due to the DW_AT_specification having the
DW_AT_declaration attribute which was being read into the real type instances
when there were forward declarations in the DWARF, causing the type to be
omitted. We now check to make sure any DW_AT_declaration values are only
respected when parsing types if the attribute is from the current DIE.
After fixing the missing types, we ran into some issues with the expression
parser finding duplicate entries for __va_list_tag since they are built in
types and would result in a "duplicate __va_list_tag definition" error. We
are now just ignoring this name during lookup, but we will need to see if
we can get the name lookup function to not get called in these cases.
Fixed an issue that would cause an assertion where DW_TAG_subroutine_types
that had no children, would not properly make a clang function type of:
"void (*) (void)".
llvm-svn: 116392
function to get the line numbers for breakpoints 1-5 during setUp().
Use a pattern to match the output from both gcc-compiled and clang-compiled binary.
This finishes the conversion of the test suite to avoid hardcoded line numbers
when setting breakpoints with either the lldb command:
breakpoint set -f filename -l lineno
or the Python API:
target.BreakpointCreateByLocation(filename, lineno)
llvm-svn: 116378
function to get the line number to break on during setUp().
Use a pattern to match the output from both gcc-compiled and clang-compiled binary.
llvm-svn: 116374

different configuration-based files using the config file. For example:
sys.stderr = open("/tmp/lldbtest-stderr", "w")
sys.stdout = open("/tmp/lldbtest-stdout", "w")
compilers = ["gcc", "llvm-gcc"]
archs = ["x86_64", "i386"]
split_stderr = True # This will split the stderr into configuration-specific file
split_stdout = True # This will split the stdout into configuration-specific file
will produce:
/tmp/lldbtest-stderr
/tmp/lldbtest-stderr.arch=i386-compiler=gcc
/tmp/lldbtest-stderr.arch=i386-compiler=llvm-gcc
/tmp/lldbtest-stderr.arch=x86_64-compiler=gcc
/tmp/lldbtest-stderr.arch=x86_64-compiler=llvm-gcc
/tmp/lldbtest-stdout
/tmp/lldbtest-stdout.arch=i386-compiler=gcc
/tmp/lldbtest-stdout.arch=i386-compiler=llvm-gcc
/tmp/lldbtest-stdout.arch=x86_64-compiler=gcc
/tmp/lldbtest-stdout.arch=x86_64-compiler=llvm-gcc
as a result of splitting stderr and stdout. In addition, each configuration can have
its individual top level relocated directory to house the test files as well as the
intermediate files by using '-r dir' to relocate the tests into a new relocated directory
instead of running the tests in place.

function. It will inspect NAME and do the following:
- if the name contains '(' or starts with "-[" or "+[" then a full name search
will happen to match full function names with args (C++ demangled names) or
full objective C method prototypes.
- if the name contains "::" and no '(', then it is assumed to be a qualified
function name that is in a namespace or class. For "foo::bar::baz" we will
search for any functions with the basename or method name of "baz", then
filter the results to only those that contain "foo::bar::baz". This allows
setting breakpoint on C++ functions and methods without having to fully
qualify all of the types that would appear in C++ mangled names.
- if the name contains ":" (not "::"), then NAME is assumed to be an ObjC
selector.
_ otherwise, we assume just a plain function basename.
Now that "--name" is our "auto" mode, I introduced the new "--basename" option
("breakpoint set --basename NAME") to allow for function names that aren't
methods or selectors, just basenames. This can also be used to ignore C++
namespaces and class hierarchies for class methods.
Fixed clang enumeration promotion types to be correct.
llvm-svn: 116293
being chopped up correctly). The DWARF plug-in also keeps a map of the ObjC
class names to selectors for easy parsing of all class selectors when we parse
the class type.

files to a different top level directory than those specified on the command line.
When relocated, the test clanups normally performed afterwards after each test method
and after each test class will not be exercised at all. This allows for an easier
postmortem analysis of test failures.
Example:
./dotest.py -v -t -r /tmp/lldbtest types
will create a /tmp/lldbtest directory which houses the types directory and its supported
files.
Files modified:
o dotest.py, lldbtest.py:
Add logic to process '-r dir' option to support relocating the tests to a different
top level directory instead of exected in place.
o darwin.py, test/types/Makefile:
The 'make clean' should only clean the minimum .o and .d files.
llvm-svn: 116255
lldb_private::RegularExpression compiles and matches with:
size_t
RegularExpression::GetErrorAsCString (char *err_str,
size_t err_str_max_len) const;
Added the ability to search a variable list for variables whose names match
a regular expression:
size_t
VariableList::AppendVariablesIfUnique (const RegularExpression& regex,
VariableList &var_list,
size_t& total_matches);
Also added the ability to append a variable to a VariableList only if it is
not already in the list:
bool
VariableList::AddVariableIfUnique (const lldb::VariableSP &var_sp);
Cleaned up the "frame variable" command:
- Removed the "-n NAME" option as this is the default way for the command to
work.
- Enable uniqued regex searches on variable names by fixing the "--regex RE"
command to work correctly. It will match all variables that match any
regular expressions and only print each variable the first time it matches.
- Fixed the option type for the "--regex" command to by eArgTypeRegularExpression
instead of eArgTypeCount
llvm-svn: 116178
Added frame relative frame selection to "frame select". You can now select
frames relative to the current frame (which defaults to zero if the current
frame hasn't yet been set for a thread):
The gdb "up" command can be done as:
(lldb) frame select -r 1
The gdb "down" command can be done as:
(lldb) frame select -r -1
Place the following in your ~/.lldbinit file for "up" and "down":
command alias up frame select -r 1
command alias down frame select -r -1
llvm-svn: 116176
as binary bytes or as an ASCII text dump.
- The output file is specified with the "--outfile FILE" option.
- The memory can be appended to an existing file using the "--append" option.
- The memory will be written as an ASCII text dump by default, or as
binary with the "--binary" option.
Added new options to memory write to allow writing all or part of
a file on disk to target memory:
- The input file is specified using the "--infile FILE" option
- The offset at which to start in the file defaults to zero, but
can be overridden using the "--offset OFFSET" option. If the
size is not specified, the remaining number of bytes in the file
will be used as the default byte size.
- The number of bytes to write defaults to the entire file byte
size, but can be changed with the "--size COUNT" option.
llvm-svn: 116172

Update the expected match string.
o lldbtest.py:
Indicate when a command fails, even if there is nothing in the error stream.
o TestHelp.py:
Add a regression test case for 'help image dump symtab'.
o CommandObjectHelp.cpp:
Some of the logic branches with successful help command results were not tagged
with a Success Status. They are fixed now. This is important for Python
interaction.
llvm-svn: 116062
Added a new SortOrder enumeration and hooked it up to the "image dump symtab"

tricks to get types to resolve. I did this by correctly including the correct
files: stdint.h and all lldb-*.h files first before including the API files.
This allowed me to remove all of the hacks that were in the lldb.swig file
and it also allows all of the #defines in lldb-defines.h and enumerations
in lldb-enumerations.h to appear in the lldb.py module. This will make the
python script code a lot more readable.
Cleaned up the "process launch" command to not execute a "process continue"
command, it now just does what it should have with the internal API calls
instead of executing another command line command.
Made the lldb_private::Process set the state to launching and attaching if
WillLaunch/WillAttach return no error respectively.
llvm-svn: 115902
Temporarily commenting out the deprecated LaunchProcess() method.
SWIG is not able to handle the overloaded functions.
o dotest.py/lldbtest.py:
Add an '-w' option to insert some wait time between consecutive test cases.
o TestClassTypes.py:
Make the breakpoint_creation_by_filespec_python() test method more robust and
more descriptive by printing out a more insightful assert message.
o lldb.swig: Coaches swig to treat StateType as an int type, instead of a C++ class.
