The above files are captured from the dbx build environment.
Rather then use a -I that points to stuff in .eng domain that
may not be accessible in other domains these files are just
copied here so local builds in other domains will work.
These files rarely change so the fact that we might have to
strobe in new ones on rare occasions is no big deal.

This import module uses a largely text-based protocol, except for
certain bulk data transfer operations. All text is in single-byte
US-ASCII.
Commands understood:
address_size ::= <int result>
Returns 32 if attached to 32-bit process, 64 if 64-bit.
peek_fail_fast <bool arg> ::=
Indicates whether "peek" requests should "fail fast"; that is, if
any of the addresses in the requested range are unmapped, report
the entire range as unmapped. This is substantially faster than
the alternative, which is to read the entire range byte-by-byte.
However, it should only be used when it is guaranteed by the
client application that peeks come from at most one page. The
default is that peek_fast_fail is not enabled.
peek <address addr> <unsigned int numBytes> ::=
B<binary char success>
[<binary unsigned int len> <binary char isMapped> [<binary char data>]...]...
NOTE that the binary portion of this message is prefixed by the
uppercase US-ASCII letter 'B', allowing easier synchronization by
clients. There is no data between the 'B' and the rest of the
message.
May only be called once attached. Reads the address space of the
target process starting at the given address (see below for format
specifications) and extending the given number of bytes. Whether
the read succeeded is indicated by a single byte containing a 1 or
0 (success or failure). If successful, the return result is given
in a sequence of ranges. _len_, the length of each range, is
indicated by a 32-bit unsigned integer transmitted with big-endian
byte ordering (i.e., most significant byte first). _isMapped_
indicates whether the range is mapped or unmapped in the target
process's address space, and will contain the value 1 or 0 for
mapped or unmapped, respectively. If the range is mapped,
_isMapped_ is followed by _data_, containing the raw binary data
for the range. The sum of all ranges' lengths is guaranteed to be
equivalent to the number of bytes requested.
poke <address addr> <int numBytes> B[<binary char data>]... ::= <bool result>
NOTE that the binary portion of this message is prefixed by the
uppercase US-ASCII letter 'B', allowing easier synchronization by
clients. There is no data between the 'B' and the rest of the
message.
Writes the given data to the target process starting at the given
address. Returns 1 on success, 0 on failure (i.e., one or more of
target addresses were unmapped).
mapped <address addr> <int numBytes> ::= <bool result>
Returns 1 if entire address range [address...address + int arg) is
mapped in target process's address space, 0 if not
lookup <symbol objName> <symbol sym> ::= <address addr>
First symbol is object name; second is symbol to be looked up.
Looks up symbol in target process's symbol table and returns
address. Returns NULL (0x0) if symbol is not found.
thr_gregs <int tid> ::= <int numAddresses> <address...>
Fetch the "general" (integer) register set for the given thread.
Returned as a series of hexidecimal values. NOTE: the meaning of
the return value is architecture-dependent. In general it is the
contents of the prgregset_t.
exit ::=
Exits the serviceability agent dbx module, returning control to
the dbx prompt.
// Data formats and example values:
<address> ::= 0x12345678[9ABCDEF0] /* up to 64-bit hex value */
<unsigned int> ::= 5 /* up to 32-bit integer number; no leading sign */
<bool> ::= 1 /* ASCII '0' or '1' */

This debug server uses a largely text-based protocol, except for
certain bulk data transfer operations. All text is in single-byte
US-ASCII except for the strings returned in "proclist".
NOTE that the character '|' (vertical bar) is used as an escape
character to switch the incoming data stream to the debug server into
binary mode, so no text command may contain that character.
Commands understood:
ascii <EOL> ::=
Changes to ASCII mode. This affects all outgoing strings. At
startup the system is in unicode mode.
unicode <EOL> ::=
Changes to UNICODE mode. This affects all outgoing strings. This
is the default mode upon startup.
proclist <EOL> ::=
<int num> [<unsigned int pid> <int charSize> <int numChars> [<binary char_t name>]...]... <EOL>
Returns integer indicating number of processes to follow, followed
by (pid, name) pairs. Names are given by (charSize, numChars,
[char_t]...) tuples; charSize indicates the size of each character
in bytes, numChars the number of characters in the string, and
name the raw data for the string. Each individual character of the
string, if multi-byte, is transmitted in network byte order.
numChars and name are guaranteed to be separated by precisely one
US-ASCII space. If process list is not available because of
limitations of the underlying operating system, number of
processes returned is 0.
attach <int pid> <EOL> ::= <bool result> <EOL>
Attempts to attach to the specified process. Returns 1 if
successful, 0 if not. Will fail if already attached or if the
process ID does not exist. Attaching to a process causes the
process to be suspended.
detach <EOL> ::= <bool result> <EOL>
Detaches from the given process. Attaching and detaching multiple
times during a debugging session is allowed. Detaching causes the
process to resume execution.
libinfo <EOL> ::=
<int numLibs> [<int charSize> <int numChars> [<binary char_t name>]... <address baseAddr>]... <EOL>
May only be called once attached and the target process must be
suspended; otherwise, returns 0. Returns list of the full path
names of all of the loaded modules (including the executable
image) in the target process, as well as the base address at which
each module was relocated. See proclist for format of strings, but
NOTE that charSize is ALWAYS 1 for this particular routine,
regardless of the setting of ASCII/UNICODE.
peek <address addr> <unsigned int numBytes> <EOL> ::=
B<binary char success>
[<binary unsigned int len> <binary char isMapped> [<binary char data>]...]...
NOTE that the binary portion of this message is prefixed by the
uppercase US-ASCII letter 'B', allowing easier synchronization by
clients. There is no data between the 'B' and the rest of the
message.
May only be called once attached. Reads the address space of the
target process starting at the given address (see below for format
specifications) and extending the given number of bytes. Whether
the read succeeded is indicated by a single byte containing a 1 or
0 (success or failure). If successful, the return result is given
in a sequence of ranges. _len_, the length of each range, is
indicated by a 32-bit unsigned integer transmitted with big-endian
byte ordering (i.e., most significant byte first). _isMapped_
indicates whether the range is mapped or unmapped in the target
process's address space, and will contain the value 1 or 0 for
mapped or unmapped, respectively. If the range is mapped,
_isMapped_ is followed by _data_, containing the raw binary data
for the range. The sum of all ranges' lengths is guaranteed to be
equivalent to the number of bytes requested.
poke <address addr> |[<binary unsigned int len> [<binary char data>]] <EOL> ::=
<bool result> <EOL>
NOTE that the binary portion of this message is prefixed by the
uppercase US-ASCII character '|' (vertical bar), allowing easier
synchronization by the server. There is no data between the '|'
and the rest of the message. ('B' is not used here because
addresses can contain that letter; no alphanumeric characters are
used because some of the parsing routines are used by the Solaris
SA port, and in that port any alphanumeric character can show up
as a part of a symbol being looked up.)
May only be called once attached. Writes the address space of the
target process starting at the given address (see below for format
specifications), extending the given number of bytes, and
containing the given data. The number of bytes is a 32-bit
unsigned integer transmitted with big-endian byte ordering (i.e.,
most significant byte first). This is followed by the raw binary
data to be placed at that address. The number of bytes of data
must match the number of bytes specified in the message.
Returns true if the write succeeded; false if it failed, for
example because a portion of the region was not mapped in the
target address space.
threadlist <EOL> ::= <int numThreads> [<address threadHandle>...] <EOL>
May only be called once attached and the target process must be
suspended; otherwise, returns 0. If available, returns handles for
all of the threads in the target process. These handles may be
used as arguments to the getcontext and selectorentry
commands. They do not need to be (and should not be) duplicated
via the duphandle command and must not be closed via the
closehandle command.
duphandle <address handle> <EOL> ::=
<bool success> [<address duplicate>] <EOL>
Duplicates a HANDLE read from the target process's address space.
HANDLE is a Windows construct (typically typedef'd to void *).
The returned handle should ultimately be closed via the
closehandle command; failing to do so can cause resource leaks.
The purpose of this command is to allow the debugger to read the
value of a thread handle from the target process and query its
register set and thread selector entries via the getcontext and
selectorentry commands, below; such use implies that the target
program has its own notion of the thread list, and further, that
the debugger has a way of locating that thread list.
closehandle <address handle> <EOL> ::=
Closes a handle retrieved via the duphandle command, above.
getcontext <address threadHandle> <EOL> ::= <bool success> [<context>] <EOL>
Returns the context for the given thread. The handle must either
be one of the handles returned from the threadlist command or the
result of duplicating a thread handle out of the target process
via the duphandle command. The target process must be suspended.
The context is returned as a series of hex values which represent
the following x86 registers in the following order:

FIXME: needs to be generalized and/or specified for other
architectures.
setcontext <address threadHandle> <context> ::= <bool success> <EOL>
Sets the context of the given thread. The target process must be
suspended. See the getcontext command for the ordering of the
registers in the context.
Even if the setcontext command succeeds, some of the bits in some
of the registers (like the global enable bits in the debug
registers) may be overridden by the operating system. To ensure
the debugger's notion of the register set is up to date, it is
recommended to follow up a setcontext with a getcontext.
selectorentry <address threadHandle> <int selector> <EOL> ::=
<bool success>
[<address limitLow> <address baseLow>
<address baseMid> <address flags1>
<address flags2> <address baseHi>] <EOL>
Retrieves a descriptor table entry for the given thread and
selector. This data structure allows conversion of a
segment-relative address to a linear virtual address. It is most
useful for locating the Thread Information Block for a given
thread handle to be able to find that thread's ID, to be able to
understand whether two different thread handles in fact refer to
the same underlying thread.
This command will only work on the X86 architecture and will
return false for the success flag (with no additional information
sent) on other architectures.
suspend ::=
Suspends the target process. Must be attached to a target process.
A process is suspended when attached to via the attach command. If
the target process is already suspended then this command has no
effect.
resume ::=
Resumes the target process without detaching from it. Must be
attached to a target process. After resuming a target process, the
debugger client must be prepared to poll for events from the
target process fairly frequently in order for execution in the
target process to proceed normally. If the target process is
already resumed then this command has no effect.
pollevent ::=
<bool eventPresent> [<address threadHandle> <unsigned int eventCode>]
Additional entries in result for given eventCode:
LOAD/UNLOAD_DLL_DEBUG_EVENT: <address baseOfDLL>
EXCEPTION_DEBUG_EVENT: <unsigned int exceptionCode> <address faultingPC>
Additional entries for given exceptionCode:
EXCEPTION_ACCESS_VIOLATION: <bool wasWrite> <address faultingAddress>
<EOL>
Polls once to see whether a debug event has been generated by the
target process. If none is present, returns 0 immediately.
Otherwise, returns 1 along with a series of textual information
about the event. The event is not cleared, and the thread resumed,
until the continueevent command is sent, or the debugger client
detaches from the target process.
Typically a debugger client will suspend the target process upon
reception of a debug event. Otherwise, it is not guaranteed that
all threads will be suspended upon reception of a debug event, and
any operations requiring that threads be suspended (including
fetching the context for the thread which generated the event)
will fail.
continueevent <bool passEventToClient> ::= <bool success> <EOL>
Indicates that the current debug event has been used by the
debugger client and that the target process should be resumed. The
passEventToClient flag indicates whether the event should be
propagated to the target process. Breakpoint and single-step
events should not be propagated to the target. Returns false if
there was no pending event, true otherwise.
exit <EOL>
Exits this debugger session.
Format specifications:
// Data formats and example values:
<EOL> ::= end of line (typically \n on Unix platforms, or \n\r on Windows)
<address> ::= 0x12345678[9ABCDEF0] /* up to 64-bit hex value */
<unsigned int> ::= 5 /* up to 32-bit integer number; no leading sign */
<bool> ::= 1 /* ASCII '0' or '1' */
<context> ::= <address> ...

This is a "Simple Windows Debug Server" written for the purpose of
enabling the Serviceability Agent on Win32. It has backends both for
Windows NT 4.0 (using internal Windows APIs for a few routines) as
well as for 95/98/ME/2000 via the Tool Help APIs.
The reason this debug server is necessary is that the Win32 debug APIs
by design tear down the target process when the debugger exits (see
knowledge base article Q164205 on msdn.microsoft.com). On Solaris, one
can attach to and detach from a process with no effect; this is key to
allowing dbx and gcore to work.
The Simple Windows Debug Server effectively implements attach/detach
functionality for arbitrary debug clients. This allows the SA to
attach non-destructively to a process, and will enable gcore for Win32
to be written shortly. While the debugger (the "client" in all of the
source code) is attached, the target process is suspended. (Note that
the debug server could be extended to support resumption of the target
process and transmission of debug events over to the debugger, but
this has been left for the future.)
The makefile (type "nmake") builds two executables: SwDbgSrv.exe,
which is the server process, and SwDbgSub.exe, which is forked by the
server and should not be directly invoked by the user.
The intent is that these two executables can be installed into
C:\WINNT\SYSTEM32 and SwDbgSrv installed to run as a service (on NT),
for example using ServiceInstaller (http://www.kcmultimedia.com/smaster/).
However, SwDbgSrv can also be run from the command line. It generates
no text output unless the source code is changed to enable debugging
printouts. As long as any processes which have been attached to by the
SA are alive, the SwDbgSrv and any forked SwDbgSub processes must be
left running. Terminating them will cause termination of the target
processes.
The debug server opens port 27000 and accepts incoming connections
from localhost only. The security model assumes that if one can run a
process on the given machine then one basically has access to most or
all of the machine's facilities; this seems to be in line with the
standard Windows security model. The protocol used is text-based, so
one can debug the debug server using telnet. See README-commands.txt
for documentation on the supported commands.
Testing indicates that the performance impact of attaching to a
process (and therefore permanently attaching a debugger) is minimal.
Some serious performance problems had been seen which ultimately
appeared to be a lack of physical memory on the machine running the
system.
Bugs:
This debug server is fundamentally incompatible with the Visual C++
debugger. Once the debug server is used to attach to a process, the
Visual C++ IDE will not be able to attach to the same process (even if
the debug server is "detached" from that process). Note that this
system is designed to work with the same primitives that C and C++
debuggers use (like "symbol lookup" and "read from process memory")
and exposes these primitives to Java, so in the long term we could
solve this problem by implementing platform-specific debug symbol
parsing and a platform-independent C++ debugger in Java.
Note:
The files IOBuf.cpp and IOBuf.hpp are also used in
building src/os/solaris/agent.
