remote & target_extra_thread_info, use cache w/ qThreadExtraInfo and qP too
The following patch will make "info threads" call target_extra_thread_info more frequently. When I looked at the remote implementation, I noticed that if we're not using qXfer:threads:read, then we'd be increasing the remote protocol traffic. This commit prevents that from happening. Also, it removes a gratuitous local static buffer, which seems good on its own. gdb/ChangeLog: 2018-06-29 Pedro Alves <palves@redhat.com> * remote.c (remote_target::extra_thread_info): Delete 'display_buf' and 'n' locals. from the cache, regardless of packet mechanims is in use. Use cache for qThreadExtra and qP methods too. |

gdb: Eliminate the 'stop_pc' global
In my multi-target work, I need to add a few more scoped_restore_current_thread and switch_to_thread calls in some places, and in some lower-level places I was fighting against the fact that switch_to_thread reads/refreshes the stop_pc global. Instead of piling on workarounds, let's just finally eliminate the stop_pc global. We already have the per-thread thread_info->suspend.stop_pc field, so it's mainly a matter of using that more/instead. gdb/ChangeLog: 2018-06-28 Pedro Alves <palves@redhat.com> * gdbthread.h (struct thread_suspend_state) <stop_pc>: Extend comments. (switch_to_thread_no_regs): Adjust comment. * infcmd.c (stop_pc): Delete. (post_create_inferior, info_program_command): Replace references to stop_pc with references to thread_info->suspend.stop_pc. * inferior.h (stop_pc): Delete declaration. * infrun.c (proceed, handle_syscall_event, fill_in_stop_func) (handle_inferior_event_1, handle_signal_stop) (process_event_stop_test, keep_going_stepped_thread) (handle_step_into_function, handle_step_into_function_backward) (print_stop_location): Replace references to stop_pc with references to thread_info->suspend.stop_pc. (struct infcall_suspend_state) <stop_pc>: Delete field.

Use thread_info and inferior pointers more throughout
This is more preparation bits for multi-target support. In a multi-target scenario, we need to address the case of different processes/threads running on different targets that happen to have the same PID/PTID. E.g., we can have both process 123 in target 1, and process 123 in target 2, while they're in reality different processes running on different machines. Or maybe we've loaded multiple instances of the same core file. Etc. To address this, in my WIP multi-target branch, threads and processes are uniquely identified by the (process_stratum target_ops *, ptid_t) and (process_stratum target_ops *, pid) tuples respectively. I.e., each process_stratum instance has its own thread/process number space. As you can imagine, that requires passing around target_ops * pointers in a number of functions where we're currently passing only a ptid_t or an int. E.g., when we look up a thread_info object by ptid_t in find_thread_ptid, the ptid_t alone isn't sufficient. In many cases though, we already have the thread_info or inferior pointer handy, but we "lose" it somewhere along the call stack, only to look it up again by ptid_t/pid. Since thread_info or inferior objects know their parent target, if we pass around thread_info or inferior pointers when possible, we avoid having to add extra target_ops parameters to many functions, and also, we eliminate a number of by ptid_t/int lookups. So that's what this patch does. In a bit more detail: - Changes a number of functions and methods to take a thread_info or inferior pointer instead of a ptid_t or int parameter. - Changes a number of structure fields from ptid_t/int to inferior or thread_info pointers. - Uses the inferior_thread() function whenever possible instead of inferior_ptid. - Uses thread_info pointers directly when possible instead of the is_running/is_stopped etc. routines that require a lookup. - A number of functions are eliminated along the way, such as: int valid_gdb_inferior_id (int num); int pid_to_gdb_inferior_id (int pid); int gdb_inferior_id_to_pid (int num); int in_inferior_list (int pid); - A few structures and places hold a thread_info pointer across inferior execution, so now they take a strong reference to the (refcounted) thread_info object to avoid the thread_info pointer getting stale. This is done in enable_thread_stack_temporaries and in the infcall.c code. - Related, there's a spot in infcall.c where using a RAII object to handle the refcount would be handy, so a gdb::ref_ptr specialization for thread_info is added (thread_info_ref, in gdbthread.h), along with a gdb_ref_ptr policy that works for all refcounted_object types (in common/refcounted-object.h). gdb/ChangeLog: 2018-06-21 Pedro Alves <palves@redhat.com> * ada-lang.h (ada_get_task_number): Take a thread_info pointer instead of a ptid_t.

Remove use of queue from remote.c
This removes a use of the queue data structure (common/queue.h) from remote.c. The queue is replaced with a std::vector. A queue was not needed, as the code never de-queued items. This removes quite a bit of boilerplate code, mostly involved with marshalling arguments to be passed through the queue iterator. Tested by the buildbot. gdb/ChangeLog 2018-06-10 Tom Tromey <tom@tromey.com> * remote.c (stop_reply_p): Remove typedef. Don't declare queue. (class remote_state) <stop_reply_queue>: Now std::vector.

target_ops::beneath -> target_ops::beneath()
This changes target_ops::beneath from a pointer to a method, and adjusts all references throughout. The idea here is to make it easier to change the target stack representation from an intrusive singly linked list to something else without leaking implementation details throughout. The commit does not change the representation yet, that will be done in a following patch. That is why a new target_ops::m_beneath field appears here. That new field isn't really documented properly or made private, simply because it will be removed shortly. Note that target_ops::beneath() is essentially the same as the current find_target_beneath routine. The following patch will eliminate the latter. gdb/ChangeLog: 2018-06-07 Pedro Alves <palves@redhat.com> * target.h (target_ops) <beneath>: Now a method. All references updated.

target_stack -> current_top_target() throughout
The recent C++ification of target_ops replaced references to the old "current_target" squashed target throughout with references to a "target_stack" pointer. I had picked the "target_stack" name very early in the multi-target work, and managed to stick with it, even though it's a bit of a misnomer, since it isn't really a "target stack" object, but a pointer into the current top target in the stack. As I'm splitting more pieces off of the multi-target branch, I've come to think that it's better to rename it now. A following patch will introduce a new class to represent a target stack, and "target_stack" would be _its_ ideal name. (In the branch, the class is called a_target_stack to work around the clash.) Thus this commit renames target_stack to current_top_target and replaces all references throughout. Also, while at it, current_top_target is made a function instead of a pointer, to make it possible to change its internal implementation without leaking implementation details out. In a couple patches, the implementation of the function will change to refer to a target stack object, and then further down the multi-target work, it'll change again to find the right target stack for the current inferior. gdb/ChangeLog: 2018-06-07 Pedro Alves <palves@redhat.com> * target.h (target_stack): Delete.

remote: one struct remote_state per struct remote_target
'struct remote_state' today contains per-connection state, however there's only a single global instance of that type. In order to support multiple connections, we must have one such object per connection. Thus this patch eliminates the 'remote_state' global in favor of having a remote_state instance per remote_target instance. The get_remote_state free function is eliminated as well, by making it a remote_target method instead. The patch then fixes the fallout by making all free functions that refer to get_remote_state() directly or indirectly be methods of remote_target too. Likewise, remote-fileio.c and remote-notif.c routines are parameterized with a remote_target pointer too, so they can call into the right remote_target instance. References to the global 'get_remote_state ()->remote_desc' to tell whether the remote target is open (!= nullptr) must be replaced with something else: - Command implementations use a new get_current_remote_target free function. - remote_target::open_1 checks the exception type instead. Finally, remote_target and extended_remote_target are made heap-allocated targets. As with the earlier core target patches, it still won't be possible to have more than one remote_target instance in practice, but this puts us closer. gdb/ChangeLog: 2018-05-22 Pedro Alves <palves@redhat.com> * remote-fileio.c (remote_fileio_reply, remote_fileio_ioerror) (remote_fileio_badfd, remote_fileio_return_errno) (remote_fileio_return_success, remote_fileio_func_open) (remote_fileio_func_open, remote_fileio_func_close) (remote_fileio_func_read, remote_fileio_func_write) (remote_fileio_func_lseek, remote_fileio_func_rename) (remote_fileio_func_unlink, remote_fileio_func_stat) (remote_fileio_func_fstat, remote_fileio_func_gettimeofday) (remote_fileio_func_isatty, remote_fileio_func_system): Add remote_target parameter.

Handle "show remote memory-write-packet-size" when not connected
Currently "show remote memory-write-packet-size" says that the packet
size is limited to whatever is stored in the remote_state global, even
if not connected to a target.
When we get to support multiple instances of remote targets, there
won't be a remote_state global anymore, so that must be replaced by
something else.
Since it doesn't make sense to print the limit of the packet size of a
non-existing connection, this patch makes us say that the limit will
be further reduced when we connect.
The text is taken from the command's online help, which says:
"The actual limit is further reduced dependent on the target."
Note that a value of "0" is special, as per "help set remote
memory-write-packet-size":
~~~
Specify the number of bytes in a packet or 0 (zero) for the
default packet size.
~~~
I've tweaked "show remote memory-write-packet-size" to include
"(default)" in the output in that case, like this:
(gdb) show remote memory-write-packet-size
The memory-write-packet-size is 0 (default). The actual limit will be further reduced dependent on the target.
While working on this, I noticed that an explicit "set remote
write-packet-size 0" does not makes GDB go back to the exact same
state as the default state when GDB starts up:
(gdb) show remote memory-write-packet-size
The memory-write-packet-size is 0. [...]
^^
(gdb) set remote memory-write-packet-size 0
(gdb) show remote memory-write-packet-size
The memory-write-packet-size is 16384. [...]
^^^^^
The "16384" number comes from DEFAULT_MAX_MEMORY_PACKET_SIZE.
This happens because git commit

remote: Move discard_pending_stop_replies call
This helps because discard_pending_stop_replies will later become a method of remote_target.

remote: multiple remote_arch_state instances per arch
Currently, we associate gdbarch-related remote protocol state on a per-gdbarch data object. Things like the size of the g/G packet, and the max remote packet size. If we'll support being connected to different remote servers at the same time, then we need to cope with each having their own packet sizes, even if they are each debugging programs of the same architecture. I.e., a single instance of remote_arch_state per arch is not sufficient. This patch moves the remote_arch_state object to a map of gdbarch-to-remote_arch_state saved in the remote_state structure. Usually there will only be one entry in the map, though we may see more with stubs that support multi-process and/or archs with multiple ABIs (e.g, one remote_arch_state for 64-bit inferiors and another for 32-bit inferiors). gdb/ChangeLog: 2018-05-22 Pedro Alves <palves@redhat.com> * remote.c: Include <unordered_map>.

Use counted_command_line everywhere
Currently command lines are reference counted using shared_ptr only when attached to breakpoints. This patch changes gdb to use shared_ptr in commands as well. This allows for the removal of copy_command_lines. Note that the change to execute_user_command explicitly makes a new reference to the command line. This will be used in a later patch. This simplifies struct command_line based on the observation that a given command can have at most two child bodies: an "if" can have both "then" and "else" parts. Perhaps the names I've chosen for the replacements here are not very good -- your input requested.

target factories, target open and multiple instances of targets
Currently, to open a target, with "target TARGET_NAME", GDB finds the target_ops instance with "TARGET_NAME" as short name, and then calls its target_ops::open virtual method. In reality, there's no actual target/name lookup, a pointer to the target_ops object was associated with the "target TARGET_NAME" command at add_target time (when GDB is initialized), as the command's context. This creates a chicken and egg situation. Consider the case of wanting to open multiple remote connections. We want to be able to have one remote target_ops instance per connection, but, if we're not connected yet, so we don't yet have an instance to call target->open() on... This patch fixes this by separating out common info about a target_ops to a separate structure (shortname, longname, doc), and changing the add_target routine to take a reference to such an object instead of a pointer to a target_ops, and a pointer to a factory function that is responsible to open an instance of the corresponding target when the user types "target TARGET_NAME". -extern void add_target (struct target_ops *); +extern void add_target (const target_info &info, target_open_ftype *func); I.e. this factory function replaces the target_ops::open virtual method. For static/singleton targets, nothing changes, the target_open_ftype function pushes the global target_ops instance on the target stack. At target_close time, the connection is tor down, but the global target_ops object remains live. However, targets that support being open multiple times will make their target_open_ftype routine allocate a new target_ops instance on the heap [e.g., new remote_target()], and push that on the stack. At target_close time, the new object is destroyed (by the target_ops::close virtual method). Both the core target and the remote targets will support being open multiple times (others could/should too, but those were my stopping point), but not in this patch yet. We need to get rid of more globals first before that'd be useful. Native targets are somewhat special, given find_default_run_target & friends. Those routines also expect to return a target_ops pointer, even before we've open the target. However, we'll never need more than one instance of the native target, so we can assume/require that native targets are global/simpletons, and have the backends register a pointer to the native target_ops. Since all native targets inherit inf_child_target, we can centralize that registration. See add_inf_child_target, get_native_target/set_native_target and find_default_run_target. gdb/ChangeLog: 2018-05-02 Pedro Alves <palves@redhat.com> * aarch64-fbsd-nat.c (_initialize_aarch64_fbsd_nat): Use add_inf_child_target. * aarch64-linux-nat.c (_initialize_aarch64_linux_nat): Use add_inf_child_target. * aix-thread.c (aix_thread_target_info): New.

Convert struct target_ops to C++
I.e., use C++ virtual methods and inheritance instead of tables of
function pointers.
Unfortunately, there's no way to do a smooth transition. ALL native
targets in the tree must be converted at the same time. I've tested
all I could with cross compilers and with help from GCC compile farm,
but naturally I haven't been able to test many of the ports. Still, I
made a best effort to port everything over, and while I expect some
build problems due to typos and such, which should be trivial to fix,
I don't expect any design problems.
* Implementation notes:
- The flattened current_target is gone. References to current_target
or current_target.beneath are replaced with references to
target_stack (the top of the stack) directly.
- To keep "set debug target" working, this adds a new debug_stratum
layer that sits on top of the stack, prints the debug, and delegates
to the target beneath.
In addition, this makes the shortname and longname properties of
target_ops be virtual methods instead of data fields, and makes the
debug target defer those to the target beneath. This is so that
debug code sprinkled around that does "if (debugtarget) ..." can
transparently print the name of the target beneath.
A patch later in the series actually splits out the
shortname/longname methods to a separate structure, but I preferred
to keep that chance separate as it is associated with changing a bit
the design of how targets are registered and open.
- Since you can't check whether a C++ virtual method is overridden,
the old method of checking whether a target_ops implements a method
by comparing the function pointer must be replaced with something
else.
Some cases are fixed by adding a parallel "can_do_foo" target_ops
methods. E.g.,:
+ for (t = target_stack; t != NULL; t = t->beneath)
{
- if (t->to_create_inferior != NULL)
+ if (t->can_create_inferior ())
break;
}
Others are fixed by changing void return type to bool or int return
type, and have the default implementation return false or -1, to
indicate lack of support.
- make-target-delegates was adjusted to generate C++ classes and
methods.
It needed tweaks to grok "virtual" in front of the target method
name, and for the fact that methods are no longer function pointers.
(In particular, the current code parsing the return type was simple
because it could simply parse up until the '(' in '(*to_foo)'.
It now generates a couple C++ classes that inherit target_ops:
dummy_target and debug_target.
Since we need to generate the class declarations as well, i.e., we
need to emit methods twice, we now generate the code in two passes.
- The core_target global is renamed to avoid conflict with the
"core_target" class.
- ctf/tfile targets
init_tracefile_ops is replaced by a base class that is inherited by
both ctf and tfile.
- bsd-uthread
The bsd_uthread_ops_hack hack is gone. It's not needed because
nothing was extending a target created by bsd_uthread_target.
- remote/extended-remote targets
This is a first pass, just enough to C++ify target_ops.
A later pass will convert more free functions to methods, and make
remote_state be truly per remote instance, allowing multiple
simultaneous instances of remote targets.
- inf-child/"native" is converted to an actual base class
(inf_child_target), that is inherited by all native targets.
- GNU/Linux
The old weird double-target linux_ops mechanism in linux-nat.c, is
gone, replaced by adding a few virtual methods to linux-nat.h's
target_ops, called low_XXX, that the concrete linux-nat
implementations override. Sort of like gdbserver's
linux_target_ops, but simpler, for requiring only one
target_ops-like hierarchy, which spares implementing the same method
twice when we need to forward the method to a low implementation.
The low target simply reimplements the target_ops method directly in
that case.
There are a few remaining linux-nat.c hooks that would be better
converted to low_ methods like above too. E.g.:
linux_nat_set_new_thread (t, x86_linux_new_thread);
linux_nat_set_new_fork (t, x86_linux_new_fork);
linux_nat_set_forget_process
That'll be done in a follow up patch.
- We can no longer use functions like x86_use_watchpoints to install
custom methods on an arbitrary base target.
The patch replaces instances of such a pattern with template mixins.
For example memory_breakpoint_target defined in target.h, or
x86_nat_target in x86-nat.h.
- linux_trad_target, MIPS and Alpha GNU/Linux
The code in the new linux-nat-trad.h/c files which was split off of
inf-ptrace.h/c recently, is converted to a C++ base class, and used
by the MIPS and Alpha GNU/Linux ports.
- BSD targets
The
$architecture x NetBSD/OpenBSD/FreeBSD
support matrix complicates things a bit. There's common BSD target
code, and there's common architecture-specific code shared between
the different BSDs. Currently, all that is stiched together to form
a final target, via the i386bsd_target, x86bsd_target,
fbsd_nat_add_target functions etc.
This introduces new fbsd_nat_target, obsd_nat_target and
nbsd_nat_target classes that serve as base/prototype target for the
corresponding BSD variant.
And introduces generic i386/AMD64 BSD targets, to be used as
template mixin to build a final target. Similarly, a generic SPARC
target is added, used by both BSD and Linux ports.
- bsd_kvm_add_target, BSD libkvm target
I considered making bsd_kvm_supply_pcb a virtual method, and then
have each port inherit bsd_kvm_target and override that method, but
that was resulting in lots of unjustified churn, so I left the
function pointer mechanism alone.

Fix remote 'g' command error handling (PR remote/9665)
'g' command returns hex-string as response so simply checking for 'E' to determine if it failed is not enough and can trigger spurious error messages. For example, invalid behaviour can be easily triggered on Cortex-M as follows: (gdb) set $r0 = 0xe0 Sending packet: $P0=e0000000#72...Packet received: OK Packet P (set-register) is supported Sending packet: $g#67...Packet received: E0000000849A0020... Remote failure reply: E0000000849A0020... This patch fixes the problem by calling putpkt()/getpkt() directly and checking result with packet_check_result(). This works fine since Enn response has odd number of bytes while proper response has even number of bytes. Also, remote_send() is now not used anywhere so it can be removed. gdb/Changelog: 2018-04-26 Andrzej Kaczmarek <andrzej.kaczmarek@codecoup.pl> PR remote/9665 * remote.c (send_g_packet): Use putpkt/getpkt/packet_check_result instead of remote_send. (remote_send): Remove. |

Enable 'set print inferior-events' and improve detach/fork/kill/exit messages
This patch aims to turn 'set print inferior-events' always on, and do
some cleanup on the messages printed by GDB when various inferior
events happen (attach, detach, fork, kill, exit).
To make sure that the patch is correct, I've tested it with a handful
of combinations of 'set follow-fork-mode', 'set detach-on-fork' and
'set print inferior-events'. In the end, I decided to make my
hand-made test into an official testcase. More on that below.
Using the following program as an example:
#include <unistd.h>
int main ()
{
fork ();
return 0;
}
We see the following outputs from the patched GDB:
- With 'set print inferior-events on':
(gdb) r
Starting program: a.out
[Detaching after fork from child process 27749]
[Inferior 1 (process 27745) exited normally]
(gdb)
- With 'set print inferior-events off':
(gdb) r
Starting program: a.out
[Inferior 1 (process 27823) exited normally]
(gdb)
Comparing this against an unpatched GDB:
- With 'set print inferior-events off' and 'set follow-fork-mode
child':
(gdb) r
Starting program: a.out
[Inferior 2 (process 5993) exited normally]
(gdb)
Compare this against an unpatched GDB:
(unpatched-gdb) r
Starting program: a.out
[New process 5702]
[Inferior 2 (process 5702) exited normally]
(unpatched-gdb)
It is possible to notice that, in this scenario, the patched GDB
will lose the '[New process %d]' message.
- With 'set print inferior-events on', 'set follow-fork-mode child'
and 'set detach-on-fork on':
(gdb) r
Starting program: a.out
[Attaching after process 27905 fork to child process 27909]
[New inferior 2 (process 27909)]
[Detaching after fork from parent process 27905]
[Inferior 1 (process 27905) detached]
[Inferior 2 (process 27909) exited normally]
(gdb)
Compare this output with an unpatched GDB, using the same settings:
(unpatched-gdb) r
Starting program: a.out
[New inferior 28033]
[Inferior 28029 detached]
[New process 28033]
[Inferior 2 (process 28033) exited normally]
[Inferior 28033 exited]
(unpatched-gdb)
As can be seen above, I've also made a few modifications to messages
that are printed when 'set print inferior-events' is on. For example,
a few of the messages did not contain the '[' and ']' as
prefix/suffix, which led to a few inconsistencies like:
Attaching after process 22995 fork to child process 22999.
[New inferior 22999]
Detaching after fork from child process 22999.
[Inferior 22995 detached]
[Inferior 2 (process 22999) exited normally]
So I took the opportunity and included the square brackets where
applicable. I have also made the existing messages more uniform, by
always printing "Inferior %d (process %d)..." where applicable. This
makes it easier to identify the inferior number and the PID number
from the messages.
As suggested by Pedro, the "[Inferior %d exited]" message from
'exit_inferior' has been removed, because it got duplicated when
'inferior-events' is on. I'm also using the
'add_{thread,inferior}_silent' versions (instead of their verbose
counterparts) on some locations, also to avoid duplicated messages.
For example, a patched GDB with 'set print inferior-events on', 'set
detach-on-fork on' and 'set follow-fork-mode child', but using
'add_thread', would print:
(gdb) run
Starting program: a.out
[Attaching after process 25088 fork to child process 25092.]
[New inferior 25092] <--- duplicated
[Detaching after fork from child process 25092.]
[Inferior 25088 detached]
[New process 25092] <--- duplicated
[Inferior 2 (process 25092) exited normally]
But if we use 'add_thread_silent' (with the same configuration as
before):
(gdb) run
Starting program: a.out
[Attaching after process 31606 fork to child process 31610]
[New inferior 2 (process 31610)]
[Detaching after fork from parent process 31606]
[Inferior 1 (process 31606) detached]
[Inferior 2 (process 31610) exited normally]
As for the tests, the configuration options being exercised are:
- follow-fork-mode: child/parent
- detach-on-fork: on/off
- print inferior-events: on/off
It was also necessary to perform adjustments on several testcases,
because the expected messages changed considerably.
Built and regtested on BuildBot, without regressions.

FreeBSD: Fix 'Couldn't get registers: Device busy' error (PR gdb/23077)
As Rajendra SY reported at <https://sourceware.org/ml/gdb-patches/2018-04/msg00399.html>, several attach-related tests are failing on FreeBSD. The "attach" command errors with "Couldn't get registers: Device busy". When the "attach" command is executed, it calls target_attach -> inf_ptrace_attach, which just does the ptrace(PT_ATTACH), it does not wait for the child to stop with SIGSTOP. Afterwards, the command is complete and we go back to the event loop. The event loop wakes up and we end up in target_wait -> fbsd_wait, and handle the SIGSTOP stop. At the end of execute_command, though, before going back to the event loop, we check if the frame language changed via check_frame_language_change(). That reads the current PC, which is what leads to the registers read that fails. The problem is that we fail to mark the attached-to thread as executing between the initial attach, and the subsequent target_wait. Until we see the thread stop with SIGSTOP, we shouldn't try to read registers off of it. I guess there may a timing issue here - if you're "lucky", the thread may stop before gdb reads its registers, masking the problem. With that fixed, check_frame_language_change() becomes a nop until the thread is marked not-executing again, after target_wait is called and we go through handle_inferior_event -> normal_stop. We haven't seen the problem on Linux because there, the target_attach implementation waits for the thread to stop before returning. Still, that's supposedly hidden from the core, since the Linux target, like most targets, is a '!to_attach_no_wait' target. This fixes: FAIL: gdb.base/attach.exp: attach1, after setting file FAIL: gdb.base/attach.exp: attach2, with no file FAIL: gdb.base/attach.exp: load file manually, after attach2 (re-read) (got interactive prompt) FAIL: gdb.base/attach.exp: attach when process' a.out not in cwd FAIL: gdb.base/dprintf-detach.exp: bai=on ds=gdb dd=on: re-attach to inferior FAIL: gdb.base/dprintf-detach.exp: bai=on ds=gdb dd=off: re-attach to inferior FAIL: gdb.base/dprintf-detach.exp: bai=on ds=call dd=on: re-attach to inferior FAIL: gdb.base/dprintf-detach.exp: bai=on ds=call dd=off: re-attach to inferior FAIL: gdb.base/dprintf-detach.exp: bai=on ds=agent dd=on: re-attach to inferior FAIL: gdb.base/dprintf-detach.exp: bai=on ds=agent dd=off: re-attach to inferior FAIL: gdb.base/dprintf-detach.exp: bai=off ds=gdb dd=on: re-attach to inferior FAIL: gdb.base/dprintf-detach.exp: bai=off ds=gdb dd=off: re-attach to inferior FAIL: gdb.base/dprintf-detach.exp: bai=off ds=call dd=on: re-attach to inferior FAIL: gdb.base/dprintf-detach.exp: bai=off ds=call dd=off: re-attach to inferior FAIL: gdb.base/dprintf-detach.exp: bai=off ds=agent dd=on: re-attach to inferior FAIL: gdb.base/dprintf-detach.exp: bai=off ds=agent dd=off: re-attach to inferior gdb/ChangeLog: 2018-04-21 Pedro Alves <palves@redhat.com> Rajendra SY <rajendra.sy@gmail.com> * inf-ptrace.c (inf_ptrace_attach): Mark the thread as executing. * remote.c (extended_remote_attach): In all-stop mode, mark the thread as executing. |

File I/O file handles after target closes
A future patch will propose making the remote target's target_ops be heap-allocated (to make it possible to have multiple instances of remote targets, for multiple simultaneous connections), and will delete/destroy the remote target at target_close time. That change trips on a latent problem, though. File I/O handles remain open even after the target is gone, with a dangling pointer to a target that no longer exists. This results in GDB crashing when it calls the target_ops backend associated with the file handle: (gdb) Disconnect Ending remote debugging. * GDB crashes deferencing a dangling pointer Backtrace: #0 0x00007f79338570a0 in main_arena () at /lib64/libc.so.6 #1 0x0000000000858bfe in target_fileio_close(int, int*) (fd=1, target_errno=0x7ffe0499a4c8) at src/gdb/target.c:2980 #2 0x00000000007088bd in gdb_bfd_iovec_fileio_close(bfd*, void*) (abfd=0x1a631b0, stream=0x223c9d0) at src/gdb/gdb_bfd.c:353 #3 0x0000000000930906 in opncls_bclose (abfd=0x1a631b0) at src/bfd/opncls.c:528 #4 0x0000000000930cf9 in bfd_close_all_done (abfd=0x1a631b0) at src/bfd/opncls.c:768 #5 0x0000000000930cb3 in bfd_close (abfd=0x1a631b0) at src/bfd/opncls.c:735 #6 0x0000000000708dc5 in gdb_bfd_close_or_warn(bfd*) (abfd=0x1a631b0) at src/gdb/gdb_bfd.c:511 #7 0x00000000007091a2 in gdb_bfd_unref(bfd*) (abfd=0x1a631b0) at src/gdb/gdb_bfd.c:615 #8 0x000000000079ed8e in objfile::~objfile() (this=0x2154730, __in_chrg=<optimized out>) at src/gdb/objfiles.c:682 #9 0x000000000079fd1a in objfile_purge_solibs() () at src/gdb/objfiles.c:1065 #10 0x00000000008162ca in no_shared_libraries(char const*, int) (ignored=0x0, from_tty=1) at src/gdb/solib.c:1251 #11 0x000000000073b89b in disconnect_command(char const*, int) (args=0x0, from_tty=1) at src/gdb/infcmd.c:3035 This goes unnoticed in current master, because the current remote target's target_ops is never destroyed nowadays, so we end up calling: remote_hostio_close -> remote_hostio_send_command which gracefully fails with FILEIO_ENOSYS if remote_desc is NULL (because the target is closed). Fix this by invalidating a target's file I/O handles when the target is closed. With this change, remote_hostio_send_command no longer needs to handle the case of being called with a closed remote target, originally added here: <https://sourceware.org/ml/gdb-patches/2008-08/msg00359.html>. gdb/ChangeLog: 2018-04-11 Pedro Alves <palves@redhat.com> * target.c (fileio_fh_t::t): Add comment.

Remove VEC(tsv_s), use std::vector instead
This patch removes VEC(tsv_s), using an std::vector instead. I C++ified trace_state_variable a bit in the process, using std::string for the name. I also thought it would be nicer to pass a const reference to target_download_trace_state_variable, since we know it will never be NULL. This highlighted that the make-target-delegates script didn't handle references well, so I adjusted this as well. It will surely be useful in the future. gdb/ChangeLog: * tracepoint.h (struct trace_state_variable): Add constructor. <name>: Change type to std::string. * tracepoint.c (tsv_s): Remove.

Make target_read_alloc & al return vectors
This patch started by changing target_read_alloc_1 to return a byte_vector, to avoid manual memory management (in target_read_alloc_1 and in the callers). To communicate failures to the callers, it actually returns a gdb::optional<gdb::byte_vector>. Adjusting target_read_stralloc was a bit more tricky, since it wants to return a buffer of char, and not gdb_byte. Since you can't just cast a gdb::byte_vector into a gdb::def_vector<char>, I made target_read_alloc_1 templated, so both versions (that return vectors of gdb_byte and char) are generated. Since target_read_stralloc now returns a gdb::char_vector instead of a gdb::unique_xmalloc_ptr<char>, a few callers need to be adjusted. gdb/ChangeLog: * common/byte-vector.h (char_vector): New type. * target.h (target_read_alloc): Return gdb::optional<byte_vector>.

Convert observers to C++
This converts observers from using a special source-generating script to be plain C++. This version of the patch takes advantage of C++11 by using std::function and variadic templates; incorporates Pedro's patches; and renames the header file to "observable.h" (this change eliminates the need for a clean rebuild). Note that Pedro's patches used a template lambda in tui-hooks.c, but this failed to compile on some buildbot instances (presumably due to differing C++ versions); I replaced this with an ordinary template function.

btrace, gdbserver: remove the to_supports_btrace target method
Remove the to_supports_btrace target method and instead rely on detecting errors when trying to enable recording. This will also provide a suitable error message explaining why recording is not possible. For remote debugging, gdbserver will now always advertise branch tracing related packets. When talking to an older GDB, this will cause GDB to try to enable branch tracing and gdbserver to report a suitable error message every time. An older gdbserver will not advertise branch tracing related packets if the one-time check failed, so a newer GDB with this patch will fail to enable branch tracing at remote_enable_btrace() rather than at btrace_enable(). The error message is the same in both cases so there should be no user-visible change. gdb/ * btrace.c (btrace_enable): Remove target_supports_btrace call. * nat/linux-btrace.c (perf_event_pt_event_type): Move.

Per-inferior target_terminal state, fix PR gdb/13211, more
In my multi-target branch I ran into problems with GDB's terminal
handling that exist in master as well, with multi-inferior debugging.
This patch adds a testcase for said problems
(gdb.multi/multi-term-settings.exp), fixes the problems, fixes PR
gdb/13211 as well (and adds a testcase for that too,
gdb.base/interrupt-daemon.exp).
The basis of the problem I ran into is the following. Consider a
scenario where you have:
- inferior 1 - started with "attach", process is running on some
other terminal.
- inferior 2 - started with "run", process is sharing gdb's terminal.
In this scenario, when you stop/resume both inferiors, you want GDB to
save/restore the terminal settings of inferior 2, the one that is
sharing GDB's terminal. I.e., you want inferior 2 to "own" the
terminal (in target_terminal::is_ours/target_terminal::is_inferior
sense).
Unfortunately, that's not what you get currently. Because GDB doesn't
know whether an attached inferior is actually sharing GDB's terminal,
it tries to save/restore its settings anyway, ignoring errors. In
this case, this is pointless, because inferior 1 is running on a
different terminal, but GDB doesn't know better.
And then, because it is only possible to have the terminal settings of
a single inferior be in effect at a time, or make one inferior/pgrp be
the terminal's foreground pgrp (aka, only one inferior can "own" the
terminal, ignoring fork children here), if GDB happens to try to
restore the terminal settings of inferior 1 first, then GDB never
restores the terminal settings of inferior 2.
This patch fixes that and a few things more along the way:
- Moves enum target_terminal::terminal_state out of the
target_terminal class (it's currently private) and makes it a
scoped enum so that it can be easily used elsewhere.
- Replaces the inflow.c:terminal_is_ours boolean with a
target_terminal_state variable. This allows distinguishing is_ours
and is_ours_for_output states. This allows finally making
child_terminal_ours_1 do something with its "output_only"
parameter.
- Makes each inferior have its own copy of the
is_ours/is_ours_for_output/is_inferior state.
- Adds a way for GDB to tell whether the inferior is sharing GDB's
terminal. Works best on Linux and Solaris; the fallback works just
as well as currently.
- With that, we can remove the inf->attach_flag tests from
child_terminal_inferior/child_terminal_ours.
- Currently target_ops.to_ours is responsible for both saving the
current inferior's terminal state, and restoring gdb's state.
Because each inferior has its own terminal state (possibly handled
by different targets in a multi-target world, even), we need to
split the inferior-saving part from the gdb-restoring part. The
patch adds a new target_ops.to_save_inferior target method for
that.
- Adds a new target_terminal::save_inferior() function, so that
sequences like:
scoped_restore_terminal_state save_state;
target_terminal::ours_for_output ();
... restore back inferiors that were
target_terminal_state::is_inferior before back to is_inferior, and
leaves inferiors that were is_ours alone.
- Along the way, this adds a default implementation of
target_pass_ctrlc to inflow.c (for inf-child.c), that handles
passing the Ctrl-C to a process running on GDB's terminal or to
some other process otherwise.
- Similarly, adds a new target default implementation of
target_interrupt, for the "interrupt" command. The current
implementation of this hook in inf-ptrace.c kills the whole process
group, but that's incorrect/undesirable because we may not be
attached to all processes in the process group. And also, it's
incorrect because inferior_process_group() doesn't really return
the inferior's real process group id if the inferior is not a
process group leader... This is the cause of PR gdb/13211 [1],
which this patch fixes. While at it, that target method's "ptid"
parameter is eliminated, because it's not really used.
- A new test is included that exercises and fixes PR gdb/13211, and
also fixes a GDB issue reported on stackoverflow that I ran into
while working on this [2]. The problem is similar to PR gdb/13211,
except that it also triggers with Ctrl-C. When debugging a daemon
(i.e., a process that disconnects from the controlling terminal and
is not a process group leader, then Ctrl-C doesn't work, you just
can't interrupt the inferior at all, resulting in a hung debug
session. The problem is that since the inferior is no longer
associated with gdb's session / controlling terminal, then trying
to put the inferior in the foreground fails. And so Ctrl-C never
reaches the inferior directly. pass_signal is only used when the
inferior is attached, but that is not the case here. This is fixed
by the new child_pass_ctrlc. Without the fix, the new
interrupt-daemon.exp testcase fails with timeout waiting for a
SIGINT that never arrives.
[1] PR gdb/13211 - Async / Process group and interrupt not working
https://sourceware.org/bugzilla/show_bug.cgi?id=13211
[2] GDB not reacting Ctrl-C when after fork() and setsid()
https://stackoverflow.com/questions/46101292/gdb-not-reacting-ctrl-c-when-after-fork-and-setsid
Note this patch does _not_ fix:
- PR gdb/14559 - The 'interrupt' command does not work if sigwait is in use
https://sourceware.org/bugzilla/show_bug.cgi?id=14559
- PR gdb/9425 - When using "sigwait" GDB doesn't trap SIGINT. Ctrl+C terminates program when should break gdb.
https://sourceware.org/bugzilla/show_bug.cgi?id=9425
The only way to fix that that I know of (without changing the kernel)
is to make GDB put inferiors in a separate session (create a
pseudo-tty master/slave pair, make the inferior run with the slave as
its terminal, and have gdb pump output/input on the master end).

Pass inferior down to target_detach and to_detach
The to_detach target_ops method implementations are currently expected to work on current_inferior/inferior_ptid. In order to make things more explicit, and remove some "shadow" parameter passing through globals, this patch adds an "inferior" parameter to to_detach. Implementations will be expected to use this instead of relying on the global. However, to keep things simple, this patch only does the minimum that is necessary to add the parameter. The following patch gives an example of how one such implementation would be adapted. If the approach is deemed good, we can then look into adapting more implementations. Until then, they'll continue to work as they do currently. gdb/ChangeLog: * target.h (struct target_ops) <to_detach>: Add inferior parameter. (target_detach): Likewise. * target.c (dispose_inferior): Pass inferior down. (target_detach): Pass inferior down.

Remove args from target detach
I was looking into adding a parameter to target_detach, and was
wondering what the args parameter was. It seems like in the distant
past, it was possible to specify a signal number when detaching. That
signal was injected in the process before it was detached. There is an
example of code handling this in linux_nat_detach. With today's GDB, I
can't get this to work. Doing "detach 15" (15 == SIGTERM) doesn't work,
because detach is a prefix command and doesn't recognize the sub-command
15. Doing "detach inferiors 15" doesn't work because it expects a list
of inferior id to detach. Therefore, I don't think there's a way of
invoking detach_command with a non-NULL args. I also didn't find any
documentation related to this feature.
I assume that this feature stopped working when detach was made a prefix
command, which is in

Create private_thread_info hierarchy
There are multiple definitions of the private_thread_info structure
compiled in the same GDB build. Because of the one definition rule, we
need to change this if we want to be able to make them non-POD (e.g. use
std::vector fields). This patch creates a class hierarchy, with
private_thread_info being an abstract base class, and all the specific
implementations inheriting from it.
In order to poison XNEW/xfree for non-POD types, it is also needed to
get rid of the xfree in thread_info::~thread_info, which operates on an
opaque type. This is replaced by thread_info::priv now being a
unique_ptr, which calls the destructor of the private_thread_info
subclass when the thread is being destroyed.
Including gdbthread.h from darwin-nat.h gave these errors:
/Users/simark/src/binutils-gdb/gdb/gdbthread.h:609:3: error: must use 'class' tag to refer to type 'thread_info' in this scope
thread_info *m_thread;
^
class
/usr/include/mach/thread_act.h:240:15: note: class 'thread_info' is hidden by a non-type declaration of 'thread_info' here
kern_return_t thread_info
^
It turns out that there is a thread_info function in the Darwin/XNU/mach API:
http://web.mit.edu/darwin/src/modules/xnu/osfmk/man/thread_info.html
Therefore, I had to add the class keyword at a couple of places in gdbthread.h,

remote: C++ify thread_item and threads_listing_context
This patch C++ifies the thread_item and threads_listing_context
structures in remote.c. thread_item::{extra,name} are changed to
std::string. As a result, there's a bit of awkwardness in
remote_update_thread_list, where we have to xstrdup those strings when
filling the private_thread_info structure. This is removed in the
following patch, where private_thread_info is also C++ified and its
corresponding fields made std::string too. The xstrdup then becomes an
std::move.
Other than that there's nothing really special, it's a usual day-to-day
VEC -> vector and char* -> std::string change. It allows removing a
cleanup in remote_update_thread_list.
Note that an overload of hex2bin that returns a gdb::byte_vector is
added, with corresponding selftests.
gdb/ChangeLog:
* remote.c (struct thread_item): Add constructor, disable copy
construction and copy assignment, define default move
construction and move assignment.
<extra, name>: Change type to std::string.
<core>: Initialize.
<thread_handle>: Make non-pointer.
(thread_item_t): Remove typedef.
(DEF_VEC_O(thread_item_t)): Remove.
(threads_listing_context) <contains_thread>: New method.
<remove_thread>: New method.
<items>: Change type to std::vector.
(clear_threads_listing_context): Remove.
(threads_listing_context_remove): Remove.
(remote_newthread_step): Use thread_item constructor, adjust to
change to std::vector.
(start_thread): Use thread_item constructor, adjust to change to
std::vector.
(end_thread): Adjust to change to std::vector and std::string.
(remote_get_threads_with_qthreadinfo): Use thread_item

std::string, use threads_listing_context methods.

(remove_new_fork_children): Adjust.
* Makefile.in (SUBDIR_UNITTESTS_SRCS): Add rsp-low-selftests.c.

Create private_inferior class hierarchy
There are currently multiple definitions of private_inferior, defined in remote.c and darwin-nat.h. The patch that poisons XNEW and friends for non-POD types trips on that, because private_inferior is freed in ~inferior(), where it is an opaque type. Since the compiler can't tell whether the type is POD, it gives an error. Also, we can't start using C++ features in these structures (make them non-POD) as long as there are multiple definitions with the same name. For these reasons, this patch makes a class hierarchy, with private_inferior being the abstract base class, and darwin_inferior & remote_inferior inheriting from it. Destruction is done through the virtual destructor. I stumbled on some suspicious code in the darwin implementation though. darwin_check_new_threads does an XCNEW(darwin_thread_t) when it finds a new thread, allocating a new structure for it (darwin_thread_t is a typedef for private_thread_info). It then VEC_safe_pushes it in a vector defined as DEF_VEC_O (a vector of objects). This means that the structure content gets copied in the vector. The thread_info object is created with the XCNEW'ed structure as the private thread info, while the rest of the code works with the instance in the vector. We have therefore two distinct instances of darwin_thread_t/private_thread_info for each thread. This is not really a problem in practice, because thread_info::priv is not used in the darwin code. I still find it weird and far from ideal, so I tried to fix it by changing the vector to be a vector of pointers. There should now be a single instance of the structure for each thread. The deallocation of the darwin_thread_t/private_thread_info structure is done by the thread_info destructor. I am able to build on macOS, but not really test, since the port seems a bit broken. I am not able to debug reliably on the machine I have access to, which runs macOS 10.12.6. gdb/ChangeLog: * inferior.h (private_inferior): Define structure type, add virtual pure destructor. (inferior) <priv>: Change type to unique_ptr. * inferior.c (private_inferior::~private_inferior): Provide default implementation. (inferior::~inferior): Don't free priv field.

Fix 'xfered>0' assertion in target.c for remote connection
We have a customer who is using a Corelis gdb server to connect to gdb. Occasionally, the gdb server will send a 0-byte block of memory for a read. When this happens, gdb gives an assertion from target.c: internal-error: target_xfer_partial: Assertion `*xfered_len > 0' failed. This problem is almost identical to that fixed in https://sourceware.org/ml/gdb-patches/2014-02/msg00636.html In this case, remote.c needs to be modified to return TARGET_XFER_EOF instead of TARGET_XFER_OK or TARGET_XFER_UNAVAILABLE when 0 bytes are transferred. gdb/ChangeLog: PR gdb/22388 * remote.c (remote_write_bytes_aux, remote_read_bytes_1, remote_read_bytes, remote_write_qxfer, remote_xfer_partial): Return TARGET_XFER_EOF if size of returned data is 0. |

s/get_regcache_arch (regcache)/regcache->arch ()/g
This patches removes get_regcache_arch, and use regache->arch () instead. The motivation of this change is that I am going to move some basic stuff into a base class of regcache. I don't need to update "client" code regcache->arch ().

Get rid of VEC (mem_region)
This patch removes VEC (mem_region). Doing so requires touching a lot of little things here and there. The fields in mem_attrib are now initialized during construction. The values match those that were in default_mem_attrib (now removed). unknown_mem_attrib is also removed, and replaced with a static method (mem_attrib::unknown) that returns the equivalent. mem_region is initialized in a way similar to mem_region_init (now removed) did. I found the organization of mem_region_list and target_mem_region_list a bit confusing. Sometimes mem_region_list points to the same vector as target_mem_region_list (and therefore does not own it), and sometimes (when the user manually edits the mem regions) points to another vector, and in this case owns it. To avoid this ambiguity, I think it is simpler to have two vectors, one for target-defined regions and one for user-defined regions, and have mem_region_list point to one or the other. There are now no vector objects dynamically allocated, both are static. The make-target-delegates script does not generate valid code when a target method returns a type with a parameter list. For this reason, I created a typedef (mem_region_vector) that's only used in the target_ops structure. If you speak perl, you are welcome to improve the script! Regtested on the buildbot. gdb/ChangeLog: * memattr.h: Don't include vec.h. (struct mem_attrib): Initialize fields. <unknown>: New static method.

Return unique_xmalloc_ptr from target_read_stralloc

Get rid of VEC(mem_range_s)
This patch replaces the last usages of VEC(mem_range_s) with std::vector<mem_range>. This allows getting rid of a few cleanups and of the DEF_VEC_O(mem_range_s). I added a test for normalize_mem_ranges to make sure I didn't break anything there. Regtested on the buildbot. gdb/ChangeLog: * memrange.h (struct mem_range): Define operator< and operator==. (mem_range_s): Remove. (DEF_VEC_O (mem_range_s)): Remove. (normalize_mem_ranges): Change parameter type to std::vector. * memrange.c (compare_mem_ranges): Remove. (normalize_mem_ranges): Change parameter type to std::vector, adjust to vector change. * exec.c (section_table_available_memory): Return vector, remove parameter. (section_table_read_available_memory): Adjust to std::vector change. * remote.c (remote_read_bytes): Adjust to std::vector change. * tracepoint.h (traceframe_available_memory): Change parameter type to std::vector. * tracepoint.c (traceframe_available_memory): Change parameter type to std::vector, adjust. * gdb/mi/mi-main.c (mi_cmd_trace_frame_collected): Adjust to std::vector change. * gdb/Makefile.in (SUBDIR_UNITTESTS_SRCS): Add unittests/memrange-selftests.c.

Make to_traceframe_info return a unique_ptr
Since this target method returns an allocated object, return a unique_ptr. It allows getting rid a some cleanups here and there. I had to shuffle the includes around. First, target.h now needs to include tracepoint.h, to get the definition of traceframe_info_up. However, the definition of enum trace_find_type was later in target, so I had to move it to tracepoint.h, so that the declaration of tfind_1 could know about it. I then had to remove the include of target.h from tracepoint.h, which caused a circular dependency (it was probably included to get enum trace_find_type in the first place anyway). Regression tested on the buildbot. gdb/ChangeLog: * target.h: Include tracepoint.h. (enum trace_find_type): Move to tracepoint.h. (struct target_ops) <to_traceframe_info>: Return a unique ptr. * tracepoint.h: Don't include target.h (enum trace_find_type): Move from target.h. (parse_traceframe_info): Return a unique ptr. * tracepoint.c (current_traceframe_info): Change type to unique ptr. (free_traceframe_info): Remove. (clear_traceframe_info): Don't manually free current_traceframe_info. (free_result): Remove. (parse_traceframe_info): Return a unique ptr. (get_traceframe_info): Adjust to unique ptr. * ctf.c (ctf_traceframe_info): Return a unique ptr. * remote.c (remote_traceframe_info): Return a unique ptr. * tracefile-tfile.c (tfile_traceframe_info): Return a unique ptr. * target-debug.h (target_debug_print_traceframe_info_up): New macro. * target-delegates.c: Regenerate. |

Constify add_prefix_cmd
This changes add_prefix_cmd to accept a const-taking function as an argument; then fixes up all the callers. In a couple of spots I had to add a non-const overload of a function, because the function is passed to two different command-adding "constructors". These overloads are temporary; once constification is complete they can be removed. This patch also fixes a typo I happened to notice while constifying. Note that this touches a couple of files (gnu-nat.c and go32-nat.c) that I can't build. So, while I made a best-effort there, I am not certain they will still compile.

Fix "Remote 'g' packet reply is too long" problems with multiple inferiors
When debugging two inferiors (or more) against gdbserver, and the inferiors have different architectures, such as e.g., on x86_64 GNU/Linux and one inferior is 64-bit while the other is 32-bit, then GDB can get confused with the different architectures in a couple spots. In both cases I ran into, GDB incorrectly ended up using the architecture of whatever happens to be the selected inferior instead of the architecture of some other given inferior: #1 - When parsing the expedited registers in stop replies. #2 - In the default implementation of the target_thread_architecture target method. These resulted in instances of the infamous "Remote 'g' packet reply is too long" error. For example, with the test added in this commit, we get: ~~~ Continuing. Remote 'g' packet reply is too long (expected 440 bytes, got 816 bytes): ad064000000000000[snip] (gdb) FAIL: gdb.multi/multi-arch.exp: inf1 event with inf2 selected: continue to hello_loop c Continuing.

Extend "set cwd" to work on gdbserver
This is the "natural" extension necessary for the "set cwd" command (and the whole "set the inferior's cwd" logic) to work on gdbserver. The idea here is to have a new remote packet, QSetWorkingDir (name adopted from LLDB's extension to the RSP, as can be seen at <https://raw.githubusercontent.com/llvm-mirror/lldb/master/docs/lldb-gdb-remote.txt>), which sends an hex-encoded string representing the working directory that the remote inferior will use. There is a slight difference from the packet proposed by LLDB: GDB's version will accept empty arguments, meaning that the user wants to clear the previously set working directory for the inferior (i.e., "set cwd" without arguments on GDB). For UNIX-like targets this feature is already implemented on nat/fork-inferior.c, and all gdbserver has to do is to basically implement "set_inferior_cwd" and call it whenever such packet arrives. For other targets, like Windows, it is possible to use the existing "get_inferior_cwd" function and do the necessary steps to make sure that the inferior will use the specified working directory. Aside from that, the patch consists basically of updates to the testcase (making it available on remote targets) and the documentation. No regressions found. gdb/ChangeLog: 2017-10-04 Sergio Durigan Junior <sergiodj@redhat.com> * NEWS (Changes since GDB 8.0): Add entry about new 'set-cwd-on-gdbserver' feature.

Remove make_cleanup_restore_target_terminal
This removes make_cleanup_restore_target_terminal and generally C++-ifies target terminal handling. It changes all target_terminal_* functions to be static members of a new target_terminal class and changes the cleanup to be a scoped_* class. make_cleanup_override_quit_handler is also removed in favor of simply using scoped_restore. Note that there are some files in this patch that I could not compile. Considering that some of the rewrites were automated, and that none of these files involed cleanups, I feel that this is relatively safe.

Implement the ability to set/unset environment variables to GDBserver when starting the inferior
This patch implements the ability to set/unset environment variables on the remote target, mimicking what GDB already offers to the user. There are two features present here: user-set and user-unset environment variables. User-set environment variables are only the variables that are explicitly set by the user, using the 'set environment' command. This means that variables that were already present in the environment when starting GDB/GDBserver are not transmitted/considered by this feature. User-unset environment variables are variables that are explicitly unset by the user, using the 'unset environment' command. The idea behind this patch is to store user-set and user-unset environment variables in two separate sets, both part of gdb_environ. Then, when extended_remote_create_inferior is preparing to start the inferior, it will iterate over the two sets and set/unset variables accordingly. Three new packets are introduced: - QEnvironmentHexEncoded, which is used to set environment variables, and contains an hex-encoded string in the format "VAR=VALUE" (VALUE can be empty if the user set a variable with a null value, by doing 'set environment VAR='). - QEnvironmentUnset, which is used to unset environment variables, and contains an hex-encoded string in the format "VAR". - QEnvironmentReset, which is always the first packet to be transmitted, and is used to reset the environment, i.e., discard any changes made by the user on previous runs. The QEnvironmentHexEncoded packet is inspired on LLDB's extensions to the RSP. Details about it can be seen here: <https://raw.githubusercontent.com/llvm-mirror/lldb/master/docs/lldb-gdb-remote.txt> I decided not to implement the QEnvironment packet because it is considered deprecated by LLDB. This packet, on LLDB, serves the same purpose of QEnvironmentHexEncoded, but sends the information using a plain text, non-hex-encoded string. The other two packets are new. This patch also includes updates to the documentation, testsuite, and unit tests, without introducing regressions. gdb/ChangeLog: 2017-08-31 Sergio Durigan Junior <sergiodj@redhat.com> * NEWS (Changes since GDB 8.0): Add entry mentioning new support for setting/unsetting environment variables on the remote target.

Fix PR remote/21852: Remote run without specifying a local binary crashes GDB
There is an assertion that is triggering when we start GDB and
instruct it to debug a remote inferior, but don't provide a local
binary, like:
./gdb -nx -q --data-directory=data-directory -ex "tar ext :1234" \
-ex "set remote exec-file /bin/ls" -ex r
In this case, when calling exec_file_locate_attach to locate the
inferior, GDB is incorrectly resetting the breakpoints without a
thread/inferior even running, which causes an assertion to be
triggered:
binutils-gdb/gdb/thread.c:1609: internal-error: scoped_restore_current_thread::scoped_restore_current_thread(): Assertion `tp != NULL' failed.
A problem internal to GDB has been detected,
further debugging may prove unreliable.
Quit this debugging session? (y or n)
This happens because add_current_inferior_and_thread (on remote.c) is
breaking an invariant: making inferior_ptid point to a non-existing
thread and then calling common code, which in this case is
breakpoint_re_set. The fix is to make sure that inferior_ptid points
to null_ptid if there is no thread present.
A testcase is provided. Regtested on buildbot.

Implement proper "startup-with-shell" support on gdbserver
This patch implements the proper support for the "startup-with-shell" feature on gdbserver. A new packet is added, QStartupWithShell, and it is sent on initialization. If the host sends a "QStartupWithShell:1", it means the inferior shall be started using a shell. If the host sends a "QStartupWithShell:0", it means the inferior shall be started without using a shell. Any other value is considered an error. There is no way to remotely set the shell that will be used by the target to start the inferior. In order to do that, the user must start gdbserver while providing a shell via the $SHELL environment variable. The same is true for the host side. The "set startup-with-shell" setting from the host side is used to decide whether to start the remote inferior using a shell. This same setting is also used to decide whether to use a shell to start the host inferior; this means that it is not really possible to start the inferior using different mechanisms on target and host. A documentation patch is included, along with a new testcase for the feature. gdb/ChangeLog: 2017-06-07 Sergio Durigan Junior <sergiodj@redhat.com> * NEWS (Changes since GDB 8.0): Announce that GDBserver is now able to start inferiors using a shell.

C++ify breakpoint class hierarchy (destructors only)
Breakpoints are currently in a limbo state between C and C++. There is
a pseudo class hierarchy implemented using struct fields. Taking
watchpoint as an example:
struct watchpoint
{
/* The base class. */
struct breakpoint base;
...
}
and it is instantianted with "new watchpoint ()". When destroyed, a
destructor is first invoked through the breakpoint_ops, and then the
memory is freed by calling delete through a pointer to breakpoint.
Address sanitizer complains about this, for example, because we new and
delete the same memory using different types.
This patch takes the logical step of making breakpoint subclasses extend
the breakpoint class for real, and converts their destructors to actual
C++ destructors.
Regtested on the buildbot.

C++-fy and prepare for sharing fork_inferior
As a preparation for the next patch, which will move fork_inferior from GDB to common/ (and therefore share it with gdbserver), it is interesting to convert a few functions to C++. This patch touches functions related to parsing command-line arguments to the inferior (see gdb/fork-child.c:breakup_args), the way the arguments are stored on fork_inferior (using std::vector instead of char **), and the code responsible for dealing with argv also on gdbserver. I've taken this opportunity and decided to constify a few arguments to fork_inferior/create_inferior as well, in order to make the code cleaner. And now, on gdbserver, we're using xstrdup everywhere and aren't checking for memory allocation failures anymore, as requested by Pedro: <https://sourceware.org/ml/gdb-patches/2017-03/msg00191.html> Message-Id: <025ebdb9-90d9-d54a-c055-57ed2406b812@redhat.com> Pedro Alves wrote: > On the "== NULL" check: IIUC, the old NULL check was there to > handle strdup returning NULL due to out-of-memory. > See NULL checks and comments further above in this function. > Now that you're using a std::vector, that doesn't work or make > sense any longer, since if push_back fails to allocate space for > its internal buffer (with operator new), our operator new replacement > (common/new-op.c) calls malloc_failure, which aborts gdbserver. > > Not sure it makes sense to handle out-of-memory specially in > the gdb/rsp-facing functions nowadays (maybe git blame/log/patch > submission for that code shows some guidelines).

IMO this refactoring was very good to increase the readability of the code as well, because some parts of the argument handling were unnecessarily confusing before. gdb/ChangeLog: 2017-04-12 Sergio Durigan Junior <sergiodj@redhat.com> * common/common-utils.c (free_vector_argv): New function. * common/common-utils.h: Include <vector>.

-Wwrite-strings: Constify target_pid_to_str and target_thread_extra_thread_info
-Wwrite-strings flagged a missing cast for example here:
static char *
ravenscar_extra_thread_info (struct target_ops *self, struct thread_info *tp)
{
return "Ravenscar task";
Since callers are not supposed to free the string returned by these
methods, change the methods' signature to return const strings.
