Fix crash in "run" on macOS when gdb is not signed
On macOS, when gdb is not code-signed, it will throw an exception from darwin_attach_pid. However, gdb also then crashes: thread.c:93: internal-error: struct thread_info *inferior_thread(): Assertion `tp' failed. I think the problem here is that darwin_attach_pid does not clean up inferior_ptid and inf->pid on failure. This leads to a situation where gdb tries to find a thread, but cannot. In other cases, gdb would mourn the inferior at this point; but here this is not possible because the target has not been pushed. Instead this patch works by simply updating the inferior and inferior_ptid on failure. Tested by building an unsigned gdb on macOS and trying to run an inferior. gdb/ChangeLog 2018-07-03 Tom Tromey <tom@tromey.com> PR cli/23340: * darwin-nat.c (darwin_attach_pid): Reset inferior and inferior_ptid on error. |

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. gdb/ChangeLog: 2018-05-02 Pedro Alves <palves@redhat.com> John Baldwin <jhb@freebsd.org> * target.h (enum strata) <debug_stratum>: New.

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. Assert that it is equal to the current inferior. * aix-thread.c (aix_thread_detach): Pass inferior down. * corefile.c (core_file_command): Pass current_inferior() down. * corelow.c (core_detach): Add inferior parameter. * darwin-nat.c (darwin_detach): Likewise. * gnu-nat.c (gnu_detach): Likewise. * inf-ptrace.c (inf_ptrace_detach): Likewise. * infcmd.c (detach_command): Pass current_inferior() down to target_detach. * infrun.c (follow_fork_inferior): Pass parent_inf to target_detach.

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, I don't really see a way around it. gdb/ChangeLog: * gdbthread.h (private_thread_info): Define structure type, add virtual pure destructor.

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.

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 (). On the other hand, this patch shortens the code a little bit. gdb: 2017-10-25 Yao Qi <yao.qi@linaro.org> * aarch32-linux-nat.c (aarch32_gp_regcache_supply): Use regcache->arch () instead get_regcache_arch. * aarch64-fbsd-nat.c (aarch64_fbsd_fetch_inferior_registers): Likewise.

darwin: Do not add a dummy thread
Starting a process on macOS/Darwin currently leads to this error: /Users/simark/src/binutils-gdb/gdb/darwin-nat.c:383: internal-error: void darwin_check_new_threads(struct inferior *): Assertion `tp' failed. with the corresponding partial backtrace (sorry, taken with lldb, because well, gdb is broken :)): frame #9: 0x000000010004605a gdb`darwin_check_new_threads(inf=0x0000000100edf670) at darwin-nat.c:383 frame #10: 0x0000000100045848 gdb`darwin_init_thread_list(inf=0x0000000100edf670) at darwin-nat.c:1710 frame #11: 0x00000001000452f8 gdb`darwin_ptrace_him(pid=8375) at darwin-nat.c:1792 frame #12: 0x0000000100041d95 gdb`fork_inferior(...) at fork-inferior.c:440 frame #13: 0x0000000100043f82 gdb`darwin_create_inferior(...) at darwin-nat.c:1841 frame #14: 0x000000010034ac32 gdb`run_command_1(args=0x0000000000000000, from_tty=1, tbreak_at_main=1) at infcmd.c:611 The issue was introduced by commit "Share fork_inferior et al with gdbserver" because it changed the place where the dummy thread (pid, 0, 0) is added, relative to the call to the init_trace_fun callback. In this callback, darwin checks for new threads in the program (there should be exactly one) in order to update this dummy thread with the right tid. Previously, things happened in this order: - fork_inferior calls fork() - fork_inferior adds dummy thread - fork_inferior calls init_trace_fun callback, which updates the dummy thread info Following the commit mentioned above, the new thread is added in the darwin-nat code, after having called fork_inferior (in darwin_create_inferior). So gdb tries to do things in this order: - fork_inferior calls fork() - fork_inferior calls init_trace_fun callback, which tries to update the dummy thread info - darwin_create_inferior adds the dummy thread The error happens while trying to update the dummy thread that has not been added yet. I don't think this dummy thread is necessary for darwin. Previously, it was fork_inferior that was adding this thread, for all targets, so darwin had to deal with it. Now that it's done by targets themselves, we can just skip that on darwin. darwin_check_new_threads called indirectly by init_trace_fun/darwin_ptrace_him will simply notice the new thread and add it with the right information. My level of testing was: try to start a process and try to attach to a process, and it seems to work somewhat like it did before. I tried to run the testsuite, but it leaves a huge amount of zombie processes that launchd doesn't seem to reap, leading to exhaustion of system resources (number of processes). gdb/ChangeLog: * darwin-nat.c (darwin_check_new_threads): Don't handle dummy thread. (darwin_init_thread_list): Don't update dummy thread. (darwin_create_inferior, darwin_attach): Don't add a dummy thread. |

darwin-nat: Add missing include
I forgot this one, which is kind of related. The function trace_start_error_with_name has moved in commit "Share fork_inferior et al with gdbserver", so this additional include is needed. Fixes: darwin-nat.c:1735:5: error: use of undeclared identifier 'trace_start_error_with_name' trace_start_error_with_name ("close"); gdb/ChangeLog: * darwin-nat.c: Include "nat/fork-inferior.h". |

Share fork_inferior et al with gdbserver
This is the most important (and the biggest, sorry) patch of the series. It moves fork_inferior from gdb/fork-child.c to nat/fork-inferior.c and makes all the necessary adjustments to both GDB and gdbserver to make sure everything works OK. There is no "most important change" with this patch; all changes are made in a progressive way, making sure that gdbserver had the necessary features while not breaking GDB at the same time. I decided to go ahead and implement a partial support for starting the inferior with a shell on gdbserver, although the full feature comes in the next patch. The user won't have the option to disable the startup-with-shell, and also won't be able to change which shell gdbserver will use (other than setting the $SHELL environment variable, that is). Everything is working as expected, and no regressions were present during the tests. gdb/ChangeLog: 2017-06-07 Sergio Durigan Junior <sergiodj@redhat.com> Pedro Alves <palves@redhat.com> * Makefile.in (HFILES_NO_SRCDIR): Add "common/common-inferior.h" and "nat/fork-inferior.h". * common/common-inferior.h: New file, with contents from "gdb/inferior.h". * commom/common-utils.c: Include "common-utils.h".

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).

PR gdb/16188: Verify PTRACE_TRACEME succeeded
This patch fixes PR gdb/16188, which is about the fact that fork_inferior doesn't verify the return value of the "traceme_fun" callback. On most targets, this callback is actually a wrapper to a ptrace call that does a PTRACE_TRACEME on the forked GDB process that will eventually become the inferior. Thanks to Pedro, this second version of the patch is simpler and more more logical. Basically, two helper functions are added: trace_start_error and trace_start_error_with_name. The former can be used when there is a customized error message to be printed to the user. The latter works like perror_with_name, so you just need to pass the function that error'd. Both helper functions mentioned above do basically the same thing: print the error message to stderr and call _exit, properly terminating the forked inferior. Most of the patch takes care of guarding the necessary system calls against errors on the "traceme_fun" callbacks. It is not right to call error on these situations, so I've replaced these calls with the proper helper function call. Regression-tested on BuildBot.

Consolidate target_mourn_inferior between GDB and gdbserver
This patch consolidates the API of target_mourn_inferior between GDB and gdbserver, in my continuing efforts to make sharing the fork_inferior function possible between both. GDB's version of the function did not care about the inferior's ptid being mourned, but gdbserver's needed to know this information. Since it actually makes sense to pass the ptid as an argument, instead of depending on a global value directly (which GDB's version did), I decided to make the generic API to accept it. I then went on and extended all calls being made on GDB to include a ptid argument (which ended up being inferior_ptid most of the times, anyway), and now we have a more sane interface. On GDB's side, after talking to Pedro a bit about it, we decided that just an assertion to make sure that the ptid being passed is equal to inferior_ptid would be enough for now, on the GDB side. We can remove the assertion and perform more operations later if we ever pass anything different than inferior_ptid. Regression tested on our BuildBot, everything OK. I'd appreciate a special look at gdb/windows-nat.c's modification because I wasn't really sure what to do there. It seemed to me that maybe I should build a ptid out of the process information there, but then I am almost sure the assertion on GDB's side would trigger. gdb/ChangeLog: 2016-09-19 Sergio Durigan Junior <sergiodj@redhat.com> * darwin-nat.c (darwin_kill_inferior): Adjusting call to target_mourn_inferior to include ptid_t argument. * fork-child.c (startup_inferior): Likewise. * gnu-nat.c (gnu_kill_inferior): Likewise. * inf-ptrace.c (inf_ptrace_kill): Likewise. * infrun.c (handle_inferior_event_1): Likewise. * linux-nat.c (linux_nat_attach): Likewise.

The issue is that we don't currently distinguish send "interrupt/ctrl-c" to target terminal vs "stop/pause" thread well; both cases go through "target_stop". And then, the native Linux backend (linux-nat.c) implements target_stop with SIGSTOP in non-stop mode, and SIGINT in all-stop mode. Since "maint set target-non-stop on" forces the backend to be always running in non-stop mode, even though the user-visible behavior is "set non-stop" is "off", "interrupt" causes a SIGSTOP instead of the SIGINT the test expects. Fix this by introducing a target_interrupt method to use in the "interrupt/ctrl-c" case, so "set non-stop off" can always work the same irrespective of "maint set target-non-stop on/off". I'm explictly considering changing the "set non-stop on" behavior as out of scope here. Most of the patch is an across-the-board rename of to_stop hook implementations to to_interrupt. The only targets where something more than a rename is being done are linux-nat.c and remote.c, which are the only targets that support async, and thus are the only ones the core side calls target_stop on. gdb/ChangeLog: 2015-08-07 Pedro Alves <palves@redhat.com> * darwin-nat.c (darwin_stop): Rename to ...

C++ keyword cleanliness, mostly auto-generated
This patch renames symbols that happen to have names which are reserved keywords in C++. Most of this was generated with Tromey's cxx-conversion.el script. Some places where later hand massaged a bit, to fix formatting, etc. And this was rebased several times meanwhile, along with re-running the script, so re-running the script from scratch probably does not result in the exact same output. I don't think that matters anyway. gdb/ 2015-02-27 Tom Tromey <tromey@redhat.com> Pedro Alves <palves@redhat.com> Rename symbols whose names are reserved C++ keywords throughout. gdb/gdbserver/ 2015-02-27 Tom Tromey <tromey@redhat.com> Pedro Alves <palves@redhat.com> Rename symbols whose names are reserved C++ keywords throughout. |

constify to_attach
This constifies the "args" argument to the target_ops to_attach method. I updated all instances of the method. I could not compile all of them but I hand-inspected them. In all cases either the argument is ignored, or it is passed to parse_pid_to_attach. (linux-nat does some extra stuff, but that one I built...) If you want to try it on your host of choice, please do so. The code in parse_pid_to_attach seems a little bogus to me. If there is a platform with a broken strtoul, we have better methods for fixing the issue now. However, I left the code as is since it is clearly ok to do so.

Native targets: Add inf-child.c:inf_child_mourn_inferior and use it.
Most ports do the same thing in the tail of their mourn routine - call generic_mourn_inferior+inf_child_maybe_unpush_target. This factors that out to a convenience function. More could be done, but this converts only the really obvious ones. Tested by building GDB on x86_64 Fedora 20, mingw32 and djgpp. The rest is untested, but I think a patch can't get more obvious. gdb/ 2014-05-21 Pedro Alves <palves@redhat.com> * inf-child.c (inf_child_mourn_inferior): New function. * inf-child.h (inf_child_mourn_inferior): New declaration. * darwin-nat.c (darwin_mourn_inferior): Use inf_child_mourn_inferior. * gnu-nat.c (gnu_mourn_inferior): Likewise. * inf-ptrace.c (inf_ptrace_mourn_inferior): Likewise. * inf-ttrace.c (inf_ttrace_mourn_inferior): Likewise. * nto-procfs.c (procfs_mourn_inferior): Likewise. * windows-nat.c (windows_mourn_inferior): Likewise. |

Allow making GDB not automatically connect to the native target.
Sometimes it's useful to be able to disable the automatic connection to the native target. E.g., sometimes GDB disconnects from the extended-remote target I was debugging, without me noticing it, and then I do "run". That starts the program locally, and only after a little head scratch session do I figure out the program is running locally instead of remotely as intended. Same thing with "attach", "info os", etc. With the patch, we now can have this instead: (gdb) set auto-connect-native-target off (gdb) target extended-remote :9999 ... *gdb disconnects* (gdb) run Don't know how to run. Try "help target". To still be able to connect to the native target with auto-connect-native-target set to off, I've made "target native" work instead of erroring out as today. Before: (gdb) target native Use the "run" command to start a native process. After: (gdb) target native Done. Use the "run" command to start a process. (gdb) maint print target-stack The current target stack is: - native (Native process) - exec (Local exec file) - None (None) (gdb) run Starting program: ./a.out ... I've also wanted this for the testsuite, when running against the native-extended-gdbserver.exp board (runs against gdbserver in extended-remote mode). With a non-native-target board, it's always a bug to launch a program with the native target. Turns out we still have one such case this patch catches: (gdb) break main Breakpoint 1 at 0x4009e5: file ../../../src/gdb/testsuite/gdb.base/coremaker.c, line 138. (gdb) run Don't know how to run. Try "help target". (gdb) FAIL: gdb.base/corefile.exp: run: with core On the patch itself, probably the least obvious bit is the need to go through all targets, and move the unpush_target call to after the generic_mourn_inferior call instead of before. This is what inf-ptrace.c does too, ever since multi-process support was added. The reason inf-ptrace.c does things in that order is that in the current multi-process/single-target model, we shouldn't unpush the target if there are still other live inferiors being debugged. The check for that is "have_inferiors ()" (a misnomer nowadays...), which does: have_inferiors (void) { for (inf = inferior_list; inf; inf = inf->next) if (inf->pid != 0) return 1; It's generic_mourn_inferior that ends up clearing inf->pid, so we need to call it before the have_inferiors check. To make all native targets behave the same WRT to explicit "target native", I've added an inf_child_maybe_unpush_target function that targets call instead of calling unpush_target directly, and as that includes the have_inferiors check, I needed to adjust the targets. Tested on x86_64 Fedora 20, native, and also with the extended-gdbserver board. Confirmed a cross build of djgpp gdb still builds. Smoke tested a cross build of Windows gdb under Wine.

Due to a thinko, a message could be not understood and ignored. The result was a dead-lock (gdb is waiting for an event that never happen).
