Greg Clayton 17499dde46 A while back in revison 244716 we added support for getting the host OS version info from debugserver. We added keys to "qHostInfo" that were "osmajor", "osminor" and "ospatch", but no one ever parsed those, so I am removing them from debugserver. We accidentally also added a "version" key to qHostInfo instead of "os_version". So now we need to support both "version" and "os_version" in qHostInfo since we have debugserver binaries out in the wild that support this old packet type. I have updated debugserver ot use the correct "os_version" for future compatability or correctness.

Sean Callanan 10badfc924 Fixed some #ifdefs. We were erroneously not supporting certain simulators.
We had some #ifdefs that were looking for the wrong #defines and as a result
debugserver didn't have support for certain simulators.  This patch resolves
the problem.

Jason Molenda 77f8935218 Changes to lldb and debugserver to reduce extraneous memory reads
at each public stop to improve performance a bit.  Most of the 
information lldb needed was already in the jThreadsInfo response;
complete that information and catch a few cases where we could still
fall back to getting the information via discrete memory reads.


debugserver adds 'associated_with_dispatch_queue' and 'dispatch_queue_t
keys to the jThreadsInfo response for all the threads.  lldb needs the
dispatch_queue_t value.  And associated_with_dispatch_queue helps to
identify which threads definitively don't have any queue information so
lldb doesn't try to do memory reads to get that information just because
it was absent in the jThreadsInfo response.

Remove the queue information from the questionmark (T) packet.  We'll
get the information for all threads via the jThreadsInfo response -
sending the information for the stopping thread (on all the private
stops, plus the less frequent public stop) was unnecessary information
being sent over the wire.

SystemRuntimeMacOSX will try to get information about queues by asking
the Threads for them, instead of reading memory.  

ProcessGDBRemote changes to recognize the new keys being sent in the
jThreadsInfo response.  Changes to ThreadGDBRemote to track the new
information.  Also, when a thread is marked as definitively not 
associated with a libdispatch queue, don't fall back to the system
runtime to try memory reads to find the queue name / kind / ID etc.

Jason Molenda 0c015c6279 In the questionmark packet ("T"), print the "threads:" and "thread-pcs:"
keys before we print the libdispatch queues keys (qname, qkind, qserialnum)
to make it easier to read the packet by hand.  No function difference, just
reordering the keys in the output.

Jason Molenda 26d84e8097 Change the key name for the libdispatch queue serial number from
"qserial" to "qserialnum" because "qserial" looks a lot like the
queue type (either 'serial' or 'concurrent') and can be confusing
to read through.  debugserver passes these up either in the questionmark
("T") packet, or in the response to the jThreadsInfo packet.

Dawn Perchik 954b40bf63 Add support for "source info" and use it to fix MI's -symbol-list-lines.
This patch adds support the command 'source info' as follows:
    (lldb) help source info
         Display source line information (as specified) based on the current executable's
         debug info.
    
    Syntax: source info <cmd-options>
    
    Command Options Usage:
      source info [-c <count>] [-s <shlib-name>] [-f <filename>] [-l <linenum>] [-e <linenum>]
      source info [-c <count>] [-s <shlib-name>] [-n <symbol>]
      source info [-c <count>] [-a <address-expression>]
    
           -a <address-expression> ( --address <address-expression> )
                Lookup the address and display the source information for the corresponding
                file and line.
    
           -c <count> ( --count <count> )
                The number of line entries to display.
    
           -e <linenum> ( --end-line <linenum> )
                The line number at which to stop displaying lines.
    
           -f <filename> ( --file <filename> )
                The file from which to display source.
    
           -l <linenum> ( --line <linenum> )
                The line number at which to start the displaying lines.
    
           -n <symbol> ( --name <symbol> )
                The name of a function whose source to display.
    
           -s <shlib-name> ( --shlib <shlib-name> )
                Look up the source in the given module or shared library (can be specified
                more than once).
For example:
    (lldb) source info --file x.h
    Lines for file x.h in compilation unit x.cpp in `x
    [0x0000000100000d00-0x0000000100000d10): /Users/dawn/tmp/./x.h:10
    [0x0000000100000d10-0x0000000100000d1b): /Users/dawn/tmp/./x.h:10

The new options are used to fix the MI command:
    -symbol-list-lines <file>
which didn't work for header files because it called:
    target modules dump line-table <file>
which only dumps line tables for a compilation unit.

The patch also fixes a bug in the error reporting when no files were supplied to the command. Previously you'd get:
    (lldb) target modules dump line-table
    error:
    Syntax:
    error: no source filenames matched any command arguments
Now you get:
    error: file option must be specified.

Jason Molenda 7e9bd599a2 Add a new "thread-pcs" key-value pair to the T packet response from
debugserver.  thread-pcs has a comma separated list of base 16
addresses - the current pc value for every thread in the process.
It is a partner of the "threads:" key where a list of thread IDs
is given.  The pc values in thread-pcs correspond one-to-one with
the thread IDs in the threads list.

This is a part of performance work.  When lldb is instruction
stepping / fast stepping over a range of addresses for e.g. a "next"
command, and it steps in to another function, lldb will put a
breakpoint on the return address and continue the process.  Before
it calls continue, it calls Thread::SetupForResume on all the
threads, and SetupForResume needs to get the current pc value for
every thread to see if any are at a breakpoint site.

The result is that issuing a "c" continue requires that we send
"read pc register" packets for every thread.

We may do this sequence of step-into-function / continue-to-get-out
many times for a single user-visible "next" or "step" command, and
with highly multithreaded programs, we are sending many extra
packets to get all the thread values.

I looked at including this data in the "jstopinfo" JSON that
we already have in the T packet.  But there are three problems that
would make this increase the size of the T packet significantly.
First, numbers in JSON are base 10.  Second, a proper JSON would
have something like "thread_pcs": { "34224331112":383772734222, ...}
for thread-id 34224331112 and pc 383772734222 - so we're including
a whole extra copy of the thread id in addition to the pc.  Third,
the JSON text is hex-ascii'fied so the size of it is doubled.
In one example, 

threads:585db8,585dc7,585dc8,585dc9,585dca,585dce;thread-pcs:100001400,7fff8badc6de,7fff8badcff6,7fff8badc6de,7fff8badc6de,7fff8badc6de;

The "thread-pcs" adds 86 characters - 136 characters for both 
threads and thread-pcs.  Doing this in JSON would look like

threads={"5791160":4294972416,"5791175":140735536809694,"5791176":140735536812022,"5791177":140735536809694,"5791178":140735536809694,"5791182":140735536809694}

or 160 characters -- or 320 characters once it is hex-asciified.

Given that it's 86 characters vrs 320, I went with the old style
approach.  I've seen real world programs that have up to 60 threads
in them, so this could result in vastly larger packets if it
was all done in the JSON with hex-ascii expansion.

If we had an all-JSON T packet, where we didn't need to hex-ascii
encode anything, that would have been the better approach.  But
we'd already have a list of threads in JSON at that point so
the additional text wouldn't be too bad.

I'm working on finishing the patches to lldb to use this data;
will commit those once I've had a chance to test them more.  But
I wanted to commit the debugserver bits which are more
straightforward.

Jason Molenda 0071be6590 When supplying memory to expedite the unwinds in the T packet,
include two stack frames worth of unwind information instead of
just one -- the unwinder is trying to fetch two stack frames in
more instances now and we're sending extra memory reads resulting
in a performance degredation while stepping.

Tamas Berghammer ccd6cffba3 Modify "platform connect" to connect to processes as well
The standard remote debugging workflow with gdb is to start the
application on the remote host under gdbserver (e.g.: gdbserver :5039
a.out) and then connect to it with gdb.

The same workflow is supported by debugserver/lldb-gdbserver with a very
similar syntax but to access all features of lldb we need to be
connected also to an lldb-platform instance running on the target.

Before this change this had to be done manually with starting a separate
lldb-platform on the target machine and then connecting to it with lldb
before connecting to the process.

This change modifies the behavior of "platform connect" with
automatically connecting to the process instance if it was started by
the remote platform. With this command replacing gdbserver in a gdb
based worflow is usually as simple as replacing the command to execute
gdbserver with executing lldb-platform.

Hafiz Abid Qadeer d122fd8d06 Better handle the arguments common to all MI commands.
Summary:
I observed that eclipse was passing --thread-group for many other commands
then we are currently handling. Looking at the MI documentation, the
following link states that each MI command accept the --thread and
--frame option. Looking at the GDB implementation, it seems that apart
from these 2, --thread-group is also handled the same way.

https://sourceware.org/gdb/onlinedocs/gdb/Context-management.html#Context-management

So instead of handling those arguments in every comamnds, I have moved
them into the base class and removed them from elsewhere. Now any command
can use these arguments. The patch seems big but most of the changes are
mechanical.

           unsigned u1;

variable name to each of the unnamed unions after "-var-list-children" command.
Also '??' incorrectly goes to 'exp' field which is treated by IDE as a
structure field name and is displayed in watch window.

The patch fixes this returning empty string as type name for unnamed union and
assigning $N to variable name, where N is the field number in the parent entity.

LLVMSupport symbols without causing duplication in the dynamic library
case.

Bruce Mitchener 6ec5d61bda Fix handling of LLDB_VERS_GENERATED_FILE.
Summary:
This is Darwin only.

The symbol defined by ${LLDB_VERS_GENERATED_FILE} is used by
source/lldb.cpp, so anything that uses lldb.cpp (which is in
lldbBase) should also have the generated symbol. This means
that the entire process can be centralized within source/CMakeLists.txt
where lldbBase is constructed.

Additionally, the custom command should have dependencies on the
project file as well as the generation script so that if either
changes, the version file is correctly re-generated and everything
is re-linked appropriately.

* cmake/LLDBDependencies.cmake: Remove everything related to
  the generated version file from here.

* source/CMakeLists.txt: On Darwin, add the generated version
  file to the sources that make up lldbBase.  Also, create a
  custom target and make lldbBase depend on it to re-generate
  the generated file as needed.

* source/API/CMakeLists.txt: Don't need to build the generated
  version file here or use it to control linking against swig_wrapper.

* tools/lldb-server/CMakeLists.txt: Likewise.

Summary:
Allow to construct CMIUtilString using std::string directly + cleanup CMIUtilString (MI)

This patch cleans up lldb-mi code, and serves to simplify
the following case:
```
  std::string strGoodbye = "!Hello";
  CMIUtilString strHello(strGoodbye.substr(1).c_str());
```

With CMIUtilString(std::string) we can omit .c_str():
```
  std::string strGoodbye = "!Hello";
  CMIUtilString strHello(strGoodbye.substr(1));
```

Also, it removes 2 ctors because they aren't needed:
# CMIUtilString::CMIUtilString(const char *const *vpData)
# CMIUtilString::CMIUtilString(const char *vpData, size_t nLen)
and cleans up CMIUtilString::operator=(const std::string &vrRhs).

Jason Molenda 9878e3b4b5 A partner to the cleanup in r247741, change the variables names in
debugserver to match.  "gcc" is now "ehframe" and "gdb" is now
"debugserver".  Because this is debugserver, what we call the Process
Plugin register numbers up in lldb are the debugserver register
numbers down here - they are the register numbers that debugserver
will use to refer to these registers over the gdb-remote protocol.

debugserver was already reporting the registers with the key
"ehframe"; this change is just cleaning up the internal variable
names to match.

llvm-svn: 247751
2015-09-15 23:49:57 +00:00
Jason Molenda 63bd0db071 Clean up register naming conventions inside lldb.
"gcc" register numbers are now correctly referred to as "ehframe"
register numbers.  In almost all cases, ehframe and dwarf register
numbers are identical (the one exception is i386 darwin where ehframe
regnums were incorrect).

The old "gdb" register numbers, which I incorrectly thought were
stabs register numbers, are now referred to as "Process Plugin"
register numbers.  This is the register numbering scheme that the
remote process controller stub (lldb-server, gdbserver, core file
support, kdp server, remote jtag devices, etc) uses to refer to the
registers.  The process plugin register numbers may not be contiguous
- there are remote jtag devices that have gaps in their register
numbering schemes.

I removed all of the enums for "gdb" register numbers that we had
in lldb - these were meaningless - and I put LLDB_INVALID_REGNUM
in all of the register tables for the Process Plugin regnum slot.

This change is almost entirely mechnical; the one actual change in
here is to ProcessGDBRemote.cpp's ParseRegisters() which parses the
qXfer:features:read:target.xml response.  As it parses register
definitions from the xml, it will assign sequential numbers as the
eRegisterKindLLDB numbers (the lldb register numberings must be
sequential, without any gaps) and if the xml file specifies register
numbers, those will be used as the eRegisterKindProcessPlugin
register numbers (and those may have gaps).  A J-Link jtag device's
target.xml does contain a gap in register numbers, and it only 
specifies the register numbers for the registers after that gap.
The device supports many different ARM boards and probably selects
different part of its register file as appropriate.

Bruce Mitchener 7dd8c12d84 [lldb-mi] Clean up CMICmdArgSet usage.
Summary:
CMICmdArgSet stores a vector of non-const pointers to the arguments
that it is validating. It owns them and is responsible for deleting
them.

We don't need to pass a const reference to the argument to
CMICmdArgSet::Add and then take the address and const_cast it
when we can just pass the argument pointer in directly.

This lets us remove some noise at every call site for CMICmdArgSet::Add
and then clean up a couple of bits inside CMICmdArgSet to remove
const_casts.

Summary:
This also moves the xcode support files to be near or the same

The source/API/liblldb.xcodes.exports differs from the
source/API/liblldb.exports in that one contains the actual
symbol names (_ prefixed) while the other contains the symbol
names as they are in the code. The liblldb.exports file is
preprocessed by the cmake scripts into the correct per-platform
file needed (like a linker script on Linux).

This is not enabled on Windows as Windows doesn't use the same
name mangling and so it won't be valid there. Also, this is handled
already in a different way on Windows (via dll exports).

This test succeeds incorrectly when the pointer is to a structured type with a char type as its first field. Fix this by switching the test to retrieve the pointee type and checking that it is a char type.

Jason Molenda 752e1e833b When debugserver fails to attach to a process on a Darwin
system, make a couple of additional checks to see if the
attach was denied via the System Integrity Protection that
is new in Mac OS X 10.11.  If so, return a special E87
error code to indicate this to lldb.

Up in lldb, if we receive the E87 error code, be specific
about why the attach failed.

Also detect the more common case of general attach failure
and print a better error message than "lost connection".

I believe this code will all build on Mac OS X 10.10 systems.
It may not compile or run on earlier versions of the OS.
None of this should build on other non-darwin systems.

Greg Clayton 2e309076f2 More packet performance improvements.
Changed the "jthreads" key/value in the stop reply packets to be "jstopinfo". This JSON only contains threads with valid stop reasons and allows us not to have to ask about other threads via qThreadStopInfo when we are stepping. The "jstopinfo" only gets sent if there are more than one thread since the stop reply packet contains all the info needed for a single thread.

Added a Process::WillPublicStop() in case process subclasses want to do any extra gathering for public stops. For ProcessGDBRemote, we end up sending a jThreadsInfo packet to gather all expedited registers, expedited memory and MacOSX queue information. We only do this for public stops to minimize the packets we send when we have multiple private stops. Multiple private stops happen when a source level single step, step into or step out run the process multiple times while implementing the stepping, and none of these private stops make it out to the UI via notifications because they are private stops.

Jason Molenda d25d72fb79 Only include the stack memory for the caller stack
frame, don't go any further, in RNBRemote::SendStopReplyPacketForThread.

These are the memory pre-fetches in the T05 packet and are
included in every private stop that lldb does.  lldb needs, at most,
the caller stack frame so we're sending more data than needed by
including additional stack memory prefetches in this reply packet.

Once we've stopped for a public stop, we're going to do a jThreadsInfo
which will include the stack memory prefetches for all threads, 
including the one which had the stop reason.

Greg Clayton a5801ade5a Added the ability to get JSON thread stop info with thread ID and stop info only in the normal stop reply packets using the new "jthreads" key value pair.
This allows stepping operations that don't ever do a public stop to get all the info they need without having to send a jThreadsInfo packet since those tend to be large.

This patch will be followed by a patch that will detect when we do a public stop, and when that happens we will send a jThreadsInfo packet at that time to get all expedited registers and memory.

Pavel Labath 77dc9569c6 Introduce a MainLoop class and switch llgs to use it
Summary:
This is the first part of our effort to make llgs single threaded. Currently, llgs consists of
about three threads and the synchronisation between them is a major source of latency when
debugging linux and android applications.

In order to be able to go single threaded, we must have the ability to listen for events from
multiple sources (primarily, client commands coming over the network and debug events from the
inferior) and perform necessary actions. For this reason I introduce the concept of a MainLoop.
A main loop has the ability to register callback's which will be invoked upon receipt of certain
events. MainLoopPosix has the ability to listen for file descriptors and signals.

For the moment, I have merely made the GDBRemoteCommunicationServerLLGS class use MainLoop
instead of waiting on the network socket directly, but the other threads still remain. In the
followup patches I indend to migrate NativeProcessLinux to this class and remove the remaining
threads.

Jason Molenda 20ee21bde6 Add a another packet to the gdb-remote protocol,
jGetLoadedDynamicLibrariesInfos.  This packet is similar to
qXfer:libraries:read except that lldb supplies the number of solibs
that should be reported about, and the start address for the list
of them.  At the initial process launch we'll read the full list
of solibs linked by the process -- at this point we could be using
qXfer:libraries:read -- but on subsequence solib-loaded notifications,
we'll be fetching a smaller number of solibs, often only one or two.

A typical Mac/iOS GUI app may have a couple hundred different 
solibs loaded  - doing all of the loads via memory reads takes 
a couple of megabytes of traffic between lldb and debugserver.
Having debugserver summarize the load addresses of all the solibs
and sending it in JSON requires a couple of hundred kilobytes
of traffic.  It's a significant performance improvement when 
communicating over a slower channel.

This patch leaves all of the logic for loading the libraries
in DynamicLoaderMacOSXDYLD -- it only call over ot ProcesGDBRemote
to get the JSON result.

If the jGetLoadedDynamicLibrariesInfos packet is not implemented,
the normal technique of using memory read packets to get all of
the details from the target will be used.

Keno Fischer 121c1c54bf Add -lpthread to LLDB shared lib link line unconditionally
Usually -lpthread is included due to LLVM link options,
but when LLVM threading is disabled, this does not happen.
pthread is still needed however because LLDB uses threading
regardless of whether LLVM is built with threading support or not.

Greg Clayton 2e59d4fffe More packet reduction when debugging with GDB server.
- Avoid sending the qfThreadInfo, qsThreadInfo packets if we have a stop reply packet with the threads already (save 2 round trip packets)
- Include the qname, qserial and qkind in the JSON info
- Report the qname, qserial and qkind to the thread so it can cache it to avoid many packets on MacOSX and iOS
- Don't clear all discoverable settings when we exec, just the ones we need to saves 1-5 packets for each exec.

Greg Clayton 358cf1ea30 Resubmitting 240466 after fixing the linux test suite failures.
A few extras were fixed

- Symbol::GetAddress() now returns an Address object, not a reference. There were places where people were accessing the address of a symbol when the symbol's value wasn't an address symbol. On MacOSX, undefined symbols have a value zero and some places where using the symbol's address and getting an absolute address of zero (since an Address object with no section and an m_offset whose value isn't LLDB_INVALID_ADDRESS is considered an absolute address). So fixing this required some changes to make sure people were getting what they expected. 
- Since some places want to access the address as a reference, I added a few new functions to symbol:
    Address &Symbol::GetAddressRef();
    const Address &Symbol::GetAddressRef() const;

Linux test suite passes just fine now.

Greg Clayton 0b90be1c4f Implement the "qSymbol" packet in order to be able to read queue information in debugserver and return the info in the stop reply packets.
A "qSymbol::" is sent when shared libraries have been loaded by hooking into the Process::ModulesDidLoad() function from within ProcessGDBRemote. This function was made virtual so that the ProcessGDBRemote version is called, which then first calls the Process::ModulesDidLoad(), and then it queries for any symbol lookups that the remote GDB server might want to do.

This allows debugserver to request the "dispatch_queue_offsets" symbol so that it can read the queue name, queue kind and queue serial number and include this data as part of the stop reply packet. Previously each thread would have to do 3 memory reads in order to read the queue name.

This is part of reducing the number of packets that are sent between LLDB and the remote GDB server.

Greg Clayton ffb2d44ab9 Reduced packet counts to the remote GDB server where possible.
We have been working on reducing the packet count that is sent between LLDB and the debugserver on MacOSX and iOS. Our approach to this was to reduce the packets required when debugging multiple threads. We currently make one qThreadStopInfoXXXX call (where XXXX is the thread ID in hex) per thread except the thread that stopped with a stop reply packet. In order to implement multiple thread infos in a single reply, we need to use structured data, which means JSON. The new jThreadsInfo packet will attempt to retrieve all thread infos in a single packet. The data is very similar to the stop reply packets, but packaged in JSON and uses JSON arrays where applicable. The JSON output looks like:


[
  { "tid":1580681,
    "metype":6,
    "medata":[2,0],
    "reason":"exception",
    "qaddr":140735118423168,
    "registers": {
      "0":"8000000000000000",
      "1":"0000000000000000",
      "2":"20fabf5fff7f0000",
      "3":"e8f8bf5fff7f0000",
      "4":"0100000000000000",
      "5":"d8f8bf5fff7f0000",

      "7":"20f4bf5fff7f0000",
      "8":"8000000000000000",
      "9":"61a8db78a61500db",

      "20":"0000000000000000"},
    "memory":[
      {"address":140734799804592,"bytes":"c8f8bf5fff7f0000c9a59e8cff7f0000"},
      {"address":140734799804616,"bytes":"00000000000000000100000000000000"}
    ]
  }
]

It contains an array of dicitionaries with all of the key value pairs that are normally in the stop reply packet. Including the expedited registers. Notice that is also contains expedited memory in the "memory" key. Any values in this memory will get included in a new L1 cache in lldb_private::Process where if a memory read request is made and that memory request fits into one of the L1 memory cache blocks, it will use that memory data. If a memory request fails in the L1 cache, it will fall back to the L2 cache which is the same block sized caching we were using before these changes. This allows a process to expedite memory that you are likely to use and it reduces packet count. On MacOSX with debugserver, we expedite the frame pointer backchain for a thread (up to 256 entries) by reading 2 pointers worth of bytes at the frame pointer (for the previous FP and PC), and follow the backchain. Most backtraces on MacOSX and iOS now don't require us to read any memory!

We will try these packets out and if successful, we should port these to lldb-server in the near future.

Jason Molenda 91ffe0a570 Add a new wart, I mean feature, on to gdb-remote protocol: compression.
For some communication channels, sending large packets can be very 
slow.  In those cases, it may be faster to compress the contents of
the packet on the target device and decompress it on the debug host
system.  For instance, communicating with a device using something
like Bluetooth may be an environment where this tradeoff is a good one.

This patch adds a new field to the response to the "qSupported" packet
(which returns a "qXfer:features:" response) -- SupportedCompressions
and DefaultCompressionMinSize.  These tell you what the remote
stub can support.

lldb, if it wants to enable compression and can handle one of those 
algorithms, it can send a QEnableCompression packet specifying the
algorithm and optionally the minimum packet size to use compression
on.  lldb may have better knowledge about the best tradeoff for
a given communication channel.

I added support to debugserver an lldb to use the zlib APIs
(if -DHAVE_LIBZ=1 is in CFLAGS and -lz is in LDFLAGS) and the
libcompression APIs on Mac OS X 10.11 and later 
(if -DHAVE_LIBCOMPRESSION=1).  libz "zlib-deflate" compression.
libcompression can support deflate, lz4, lzma, and a proprietary
lzfse algorithm.  libcompression has been hand-tuned for Apple
hardware so it should be preferred if available.

debugserver currently only adds the SupportedCompressions when
it is being run on an Apple watch (TARGET_OS_WATCH).  Comment
that #if out from RNBRemote.cpp if you want to enable it to
see how it works.  I haven't tested this on a native system
configuration but surely it will be slower to compress & decompress
the packets in a same-system debug session.

I haven't had a chance to add support for this to 
GDBRemoteCommunciationServer.cpp yet.

Bruce Mitchener 1425b47773 [LLDB-MI] Properly detect missing mandatory arguments to MI commands
Summary:
Previously if an MI command had **X** mandatory and **Y** optional arguments you could provide **X** or more optional arguments without providing any of the mandatory arguments, and the argument validation code wouldn't complain.

For example this would pass argument validation even though the mandatory **address** and **count** arguments are missing:

-data-read-memory-bytes --thread 1 --frame 0

Part of the problem was that an empty string was considered a valid value for a mandatory argument, which didn't make much sense.

Since interaction with the python interpreter is moving towards
being more isolated, we won't be able to include this header from
normal files anymore, all includes of it should be localized to
the python library which will live under source/bindings/API/Python

Greg Clayton b30c50c8fa Add a new "qEcho" packet with the following format:
qEcho:%s

where '%s' is any valid string. The response to this packet is the exact packet itself with no changes, just reply with what you received!

This will help us to recover from packets timing out much more gracefully. Currently if a packet times out, LLDB quickly will hose up the debug session. For example, if we send a "abc" packet and we expect "ABC" back in response, but the "abc" command takes longer than the current timeout value this will happen:


--> "abc"
<-- <<<error: timeout>>>

Now we want to send "def" and get "DEF" back:

--> "def"
<-- "ABC"

We got the wrong response for the "def" packet because we didn't sync up with the server to clear any current responses from previously issues commands.

The fix is to modify GDBRemoteCommunication::WaitForPacketWithTimeoutMicroSecondsNoLock() so that when it gets a timeout, it syncs itself up with the client by sending a "qEcho:%u" where %u is an increasing integer, one for each time we timeout. We then wait for 3 timeout periods to sync back up. So the above "abc" session would look like:

--> "abc"
<-- <<<error: timeout>>> 1 second
--> "qEcho:1"
<-- <<<error: timeout>>> 1 second
<-- <<<error: timeout>>> 1 second
<-- "abc"
<-- "qEcho:1"

The first timeout is from trying to get the response, then we know we timed out and we send the "qEcho:1" packet and wait for 3 timeout periods to get back in sync knowing that we might actually get the response for the "abc" packet in the mean time...

In this case we would actually succeed in getting the response for "abc". But lets say the remote GDB server is deadlocked and will never response, it would look like:

--> "abc"
<-- <<<error: timeout>>> 1 second
--> "qEcho:1"
<-- <<<error: timeout>>> 1 second
<-- <<<error: timeout>>> 1 second
<-- <<<error: timeout>>> 1 second

We then disconnect and say we lost connection.

We might also have a bad GDB server that just dropped the "abc" packet on the floor. We can still recover in this case and it would look like:

--> "abc"
<-- <<<error: timeout>>> 1 second
--> "qEcho:1"
<-- "qEcho:1"

Then we know our remote GDB server is still alive and well, and it just dropped the "abc" response on the floor and we can continue to debug.

Greg Clayton d04f0edad9 Added XML to the host layer.
We know have on API we should use for all XML within LLDB in XML.h. This API will be easy back the XML parsing by different libraries in case libxml2 doesn't work on all platforms. It also allows the only place for #ifdef ...XML... to be in XML.h and XML.cpp. The API is designed so it will still compile with or without XML support and there is a static function "bool XMLDocument::XMLEnabled()" that can be called to see if XML is currently supported. All APIs will return errors, false, or nothing when XML isn't enabled.

Converted all locations that used XML over to using the host XML implementation.

Added target.xml support to debugserver. Extended the XML register format to work for LLDB by including extra attributes and elements where needed. This allows the target.xml to replace the qRegisterInfo packets and allows us to fetch all register info in a single packet.

Vince Harron 9753dd98b3 Add support for ./dotest.py --channel and --log-success
Summary:
New dotest options that allow arbitrary log channels and
categories to be enabled.  Also enables logging for locally run
debug servers.
    
Log messages are separated into separate files per test case.
(this makes it possible to log in dosep runs)
    
These new log files are stored side-by-side with trace files in the
session directory.
    
These files are deleted by default if the test run is successful.
    
If --log-success is specified, even successful logs are retained.
    
--log-success is useful for creating reference log files.
    
Test Plan:
add '--channel "lldb all" --channel "gdb-remote packets" --log-success'
to your dotest options

Tested on OSX and Linux

Greg Clayton 3d415cd2cd qProcessInfo was not correctly detecting the sysctl value for "hw.cpu64bit_capable".
It was just detecting the existance of the value. If it gets the value correctly, we need to check that it is non-zero to see if cpu64bit_capable should be true.

Ilia K 7bb59b360b Implement -target-attach and -target-detach
Summary:
This changes add -target-attach and -target-detach. 

-target-attach allows lldb-mi to attach to an existing process by it's process id, matching gdb mi's syntax of '-target-attach <pid'. Additionally, support has been added for attaching to a process by name using '-target-attach -n <name>'. Combining this with --waitfor will allow lldb mi to attach to a process by name when the process starts. 

-target-detach simply detaches from the current process

Patch from chuckr@microsoft.com

Test Plan: I have added three tests, one each for -target-attach <pid>, -target-attach -n <name>, and -target-attach -n <name> --waitfor

- The -o (offset) option is now properly handled, not just silently ignored.
- The --thread option is now properly handled.
- A new --frame option has been added for consistency with GDB.
- Added a new test to verify old and new functionality.
