2019-07-09Rename common to gdbsupportTom Tromey1-2/+2
This is the next patch in the ongoing series to move gdbsever to the top level. This patch just renames the "common" directory. The idea is to do this move in two parts: first rename the directory (this patch), then move the directory to the top. This approach makes the patches a bit more tractable. I chose the name "gdbsupport" for the directory. However, as this patch was largely written by sed, we could pick a new name without too much difficulty. Tested by the buildbot. gdb/ChangeLog 2019-07-09 Tom Tromey <tom@tromey.com> * contrib/ari/gdb_ari.sh: Change common to gdbsupport. * configure: Rebuild. * configure.ac: Change common to gdbsupport. *

2019-03-13Change pid_to_str to return std::stringTom Tromey1-10/+7
Currently the target pid_to_str method returns a const char *, so many implementations have a static buffer that they update. This patch changes these methods to return a std::string instead. I think this is cleaner and avoids possible gotchas when calling pid_to_str on different ptids in a single statement. (Though no such calls exist currently.) This also updates various helper functions, and the gdbarch pid_to_str methods. I also made a best effort to fix all the callers, but I can't build some of the *-nat.c files.

2019-03-05Remove excess calls to gdb_flushTom Tromey1-2/+0
A customer noticed some mildly odd MI output, where CLI output was split into multiple MI strings at unusual boundaries, like this: ~"$1 = (b => true" ~", p => 0x407260" This is technically correct according to the MI spec, but still unusual, in that there's no particular reason for the string to be split where it is. I tracked this down to a call to gdb_flush in generic_val_print. Then, I went through all calls to gdb_flush and removed the ones I thought were superfluous. In particular: * Any call in the value-printing code; * Likewise the type-printing code (just a single call); and * Any call that immediately followed a printf that obviously ended with a newline, my belief being that gdb's standard output streams are line buffered (by inheriting the behavior from stdio) Regression tested on x86-64 Fedora 29. I didn't add a new test case. I tend to think we don't necessarily want to specify this behavior in the tests. Let me know what you think of this. gdb/ChangeLog 2019-03-05 Tom Tromey <tromey@adacore.com> * windows-nat.c (windows_nat_target::attach) (windows_nat_target::detach): Don't call gdb_flush. * valprint.c (generic_val_print, val_print, val_print_string): Don't call gdb_flush. * utils.c (defaulted_query): Don't call gdb_flush. * typeprint.c (print_type_scalar): Don't call gdb_flush. * target.c (target_announce_detach): Don't call gdb_flush. * sparc64-tdep.c (adi_print_versions): Don't call gdb_flush. * remote.c (extended_remote_target::attach): Don't call gdb_flush. * procfs.c (procfs_target::detach): Don't call gdb_flush. * printcmd.c (do_examine): Don't call gdb_flush.

2019-01-24target_pass_signals/target_program_signals: Use gdb::array_viewPedro Alves1-4/+4
This replaces the pointer and length parameters of target_pass_signals and target_program_signals with a gdb::array_view parameter, and fixes the fallout. In infrun.c, the signal_stop, signal_print, signal_program, signal_catch, signal_pass globals are currently pointers to heap-allocated memory. I see no point in that, so I converted them to arrays. This allows simplifying the calls to target_pass_signals/target_program_signals, since we can pass the array directly, which can implicitly convert to gdb::array_view. gdb/ChangeLog: 2019-01-24 Pedro Alves <palves@redhat.com> * infrun.c (signal_stop, signal_print, signal_program) (signal_catch, signal_pass): Now arrays instead of pointers. (update_signals_program_target, do_target_resume) (signal_catch_update, handle_command, _initialize_infrun): Adjust. * linux-nat.c (linux_nat_target::pass_signals) (linux_nat_target::create_inferior, linux_nat_target::attach): Adjust. * linux-nat.h (linux_nat_target::pass_signals): Adjust. * nto-procfs.c (nto_procfs_target::pass_signals): Adjust. * procfs.c (procfs_target::pass_signals): Adjust. * record-full.c (record_full_target::resume): Adjust. * remote.c (remote_target::pass_signals) (remote_target::program_signals): Adjust. * target-debug.h (target_debug_print_signals): Now takes a gdb::array_view as parameter. Adjust. * target.h (target_ops) <pass_signals, program_signals>: Replace pointer and length parameters with gdb::array_view.

This commit applies all changes made after running the gdb/copyright.py script. Note that one file was flagged by the script, due to an invalid copyright header (gdb/unittests/basic_string_view/element_access/char/empty.cc). As the file was copied from GCC's libstdc++-v3 testsuite, this commit leaves this file untouched for the time being; a patch to fix the header was sent to gcc-patches first. gdb/ChangeLog: Update copyright year range in all GDB files.
2018-11-22Per-inferior thread list, thread ranges/iterators, down with ALL_THREADS, etc.Pedro Alves1-2/+0
As preparation for multi-target, this patch makes each inferior have its own thread list. This isn't absolutely necessary for multi-target, but simplifies things. It originally stemmed from the desire to eliminate the init_thread_list calls sprinkled around, plus it makes it more efficient to iterate over threads of a given inferior (no need to always iterate over threads of all inferiors). We still need to iterate over threads of all inferiors in a number of places, which means we'd need adjust the ALL_THREADS / ALL_NON_EXITED_THREADS macros. However, naively tweaking those macros to have an extra for loop, like: #define ALL_THREADS (thr, inf) \ for (inf = inferior_list; inf; inf = inf->next) \ for (thr = inf->thread_list; thr; thr = thr->next) causes problems with code that does "break" or "continue" within the ALL_THREADS loop body. Plus, we need to declare the extra "inf" local variable in order to pass it as temporary variable to ALL_THREADS (etc.) It gets even trickier when we consider extending the macros to filter out threads matching a ptid_t and a target. The macros become tricker to read/write. Been there. An alternative (which was my next attempt), is to replace the ALL_THREADS etc. iteration style with for_each_all_threads, for_each_non_exited_threads, etc. functions which would take a callback as parameter, which would usually be passed a lambda. However, I did not find that satisfactory at all, because the resulting code ends up a little less natural / more noisy to read, write and debug/step-through (due to use of lambdas), and in many places where we use "continue;" to skip to the next thread now need to use "return;". (I ran into hard to debug bugs caused by a continue/return confusion.) I.e., before: ALL_NON_EXITED_THREADS (tp) { if (tp->not_what_I_want) continue; // do something } would turn into: for_each_non_exited_thread ([&] (thread_info *tp) { if (tp->not_what_I_want) return; // do something }); Lastly, the solution I settled with was to replace the ALL_THREADS / ALL_NON_EXITED_THREADS / ALL_INFERIORS macros with (C++20-like) ranges and iterators, such that you can instead naturaly iterate over threads/inferiors using range-for, like e.g,.: // all threads, including THREAD_EXITED threads. for (thread_info *tp : all_threads ()) { .... } // all non-exited threads. for (thread_info *tp : all_non_exited_threads ()) { .... } // all non-exited threads of INF inferior. for (thread_info *tp : inf->non_exited_threads ()) { .... } The all_non_exited_threads() function takes an optional filter ptid_t as parameter, which is quite convenient when we need to iterate over threads matching that filter. See e.g., how the set_executing/set_stop_requested/finish_thread_state etc. functions in thread.c end up being simplified. Most of the patch thus is about adding the infrustructure for allowing the above. Later on when we get to actual multi-target, these functions/ranges/iterators will gain a "target_ops *" parameter so that e.g., we can iterate over all threads of a given target that match a given filter ptid_t. The only entry points users needs to be aware of are the all_threads/all_non_exited_threads etc. functions seen above. Thus, those functions are declared in gdbthread.h/inferior.h. The actual iterators/ranges are mainly "internals" and thus are put out of view in the new thread-iter.h/thread-iter.c/inferior-iter.h files. That keeps the gdbthread.h/inferior.h headers quite a bit more readable. A common/safe-iterator.h header is added which adds a template that can be used to build "safe" iterators, which are forward iterators that can be used to replace the ALL_THREADS_SAFE macro and other instances of the same idiom in future. There's a little bit of shuffling of code between gdbthread.h/thread.c/inferior.h in the patch. That is necessary in order to avoid circular dependencies between the gdbthread.h/inferior.h headers. As for the init_thread_list calls sprinkled around, they're all eliminated by this patch, and a new, central call is added to inferior_appeared. Note how also related to that, there's a call to init_wait_for_inferior in remote.c that is eliminated. init_wait_for_inferior is currently responsible for discarding skipped inline frames, which had to be moved elsewhere. Given that nowadays we always have a thread even for single-threaded processes, the natural place is to delete a frame's inline frame info when we delete the thread. I.e., from clear_thread_inferior_resources. gdb/ChangeLog: 2018-11-22 Pedro Alves <palves@redhat.com> * Makefile.in (COMMON_SFILES): Add thread-iter.c. * breakpoint.c (breakpoints_should_be_inserted_now): Replace ALL_NON_EXITED_THREADS with all_non_exited_threads.

2018-05-03target factories, target open and multiple instances of targetsPedro Alves1-17/+21
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.

2018-05-03Convert struct target_ops to C++Pedro Alves1-159/+173
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.

2018-01-30Per-inferior target_terminal state, fix PR gdb/13211, morePedro Alves1-2/+2
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.

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). gdb/ChangeLog: 2018-01-30 Pedro Alves <palves@redhat.com> PR gdb/13211 * config.in, configure: Regenerate. * configure.ac: Check for getpgid. * go32-nat.c (go32_pass_ctrlc): New.

2018-01-19Pass inferior down to target_detach and to_detachSimon Marchi1-1/+1
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.

2018-01-19Remove args from target detachSimon Marchi1-6/+2
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 f73adfeb8bae36885e6ea248d12223ab0d5eb9cb (sorry, there's no commit title) from 2006. Given that this feature was broken for such a long time and we haven't heard anything (AFAIK, I did not find any related bug), I think it's safe to remove it, as well as the args parameter to target_detach. If someone wants to re-introduce it, I would suggest rethinking the user interface, and in particular would suggest using signal name instead of numbers. I tried to fix all the impacted code, but I might have forgotten some spots. It shouldn't be hard to fix if that's the case. I also couldn't build-test everything I changed, especially the nto and solaris stuff. gdb/ChangeLog: * target.h (struct target_ops) <to_detach>: Remove args parameter.

gdb/ChangeLog: Update copyright year range in all GDB files
2017-11-24Create private_thread_info hierarchySimon Marchi1-22/+8
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.

2017-09-20Remove make_cleanup_restore_target_terminalTom Tromey1-1/+1
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. Regression tested by the buildbot. gdb/ChangeLog 2017-09-20 Tom Tromey <tom@tromey.com> * windows-nat.c (get_windows_debug_event, windows_wait) (do_initial_windows_stuff, windows_attach): Update. * utils.c (vwarning, internal_vproblem): Update.

2017-04-12C++-fy and prepare for sharing fork_inferiorSergio Durigan Junior1-4/+5
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).

2016-09-19Consolidate target_mourn_inferior between GDB and gdbserverSergio Durigan Junior1-2/+2
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.

(_initialize_nto_tdep): New forward declaration, new function. * nto-tdep.h (struct nto_inferior_data): New struct. (nto_inferior_data): New function declaration.
2015-10-20[nto] Implement procfs_pid_to_exec_file.Aleksandar Ristovski1-0/+28
gdb/ChangeLog: * gdb/nto-procfs.c (procfs_pid_to_exec_file): New function. (init_procfs_targets): Wire new function.
2015-10-20[nto] Implement TARGET_OBJECT_AUXV.Aleksandar Ristovski1-0/+34
Fix 'info auxv' for nto. gdb/ChangeLog: * nto-procfs.c (sys/auxv.h): Include. (procfs_xfer_partial): Implement TARGET_OBJECT_AUXV. * nto-tdep.c (nto_read_auxv_from_initial_stack): New function. * nto-tdep.h (nto_read_auxv_from_initial_stack): New declaration.
2015-10-20[nto] Fixes for nto procfs.Aleksandar Ristovski1-25/+38
Fix errnoeus construction of procfs path. The issue is, after the first info pidlist or first run, the path for local node (the most common node) will be reset to empty which makes subsequent queries and runs impossible. gdb/ChangeLog: * nto-procfs.c (nto_procfs_path): Rename to... (nodestr): ... this, and change type. (nto_node): Use new variable and logic accordingly. (procfs_open_1): Use new variable name. Use local buffer to construct procfrs path. (procfs_pidlist): Use NODESTR to construct procfs path. (procfs_files_info): Use NODESTR to output meaningful text. (do_attach): Construct procfs using NODESTR. (procfs_create_inferior): Compare pointer to NULL.
2015-10-16[nto] Fix nto build.Aleksandar Ristovski1-14/+11

2015-08-27gdb: Use sighandler_t everywherePedro Alves1-2/+2
This fixes 14 build errors like these in C++ mode: src/gdb/extension.c: In function ‘void install_sigint_handler(const signal_handler*)’: src/gdb/extension.c:698:41: error: invalid conversion from ‘void (*)()’ to ‘__sighandler_t {aka void (*)(int)}’ [-fpermissive] signal (SIGINT, handler_state->handler); ^ In file included from build-gnulib/import/signal.h:52:0, from ../../src/gdb/extension.c:24: /usr/include/signal.h:102:23: error: initializing argument 2 of ‘void (* signal(int, __sighandler_t))(int)’ [-fpermissive] extern __sighandler_t signal (int __sig, __sighandler_t __handler) ^ Instead of this everywhere: - RETSIGTYPE (*handle_sigint_for_compare) () = handle_sigint; + RETSIGTYPE (*handle_sigint_for_compare) (int) = handle_sigint; Use sighandler_t (a GNU extension). That's OK to use unconditionaly because gnulib's signal.h replacement makes sure that it is available. gdb/ChangeLog: 2015-08-27 Pedro Alves <palves@redhat.com> * cp-support.c (gdb_demangle): Use sighandler_t. Remove cast. * extension-priv.h: Include signal.h.

(procfs_wait): Remove casts. * remote-m32r-sdi.c (m32r_wait, m32r_load): Use sighandler_t. * remote-sim.c (gdbsim_wait): Use sighandler_t. * utils.c (wait_to_die_with_timeout): Use sighandler_t.
2015-08-26Replace some xmalloc-family functions with XNEW-family onesSimon Marchi1-1/+1
This patch is part of the make-gdb-buildable-in-C++ effort. The idea is to change some calls to the xmalloc family of functions to calls to the equivalents in the XNEW family. This avoids adding an explicit cast, so it keeps the code a bit more readable. Some of them also map relatively well to a C++ equivalent (XNEW (struct foo) -> new foo), so it will be possible to do scripted replacements if needed. I only changed calls that were obviously allocating memory for one or multiple "objects". Allocation of variable sizes (such as strings or buffer handling) will be for later (and won't use XNEW). - xmalloc (sizeof (struct foo)) -> XNEW (struct foo) - xmalloc (num * sizeof (struct foo)) -> XNEWVEC (struct foo, num) - xcalloc (1, sizeof (struct foo)) -> XCNEW (struct foo) - xcalloc (num, sizeof (struct foo)) -> XCNEWVEC (struct foo, num) - xrealloc (p, num * sizeof (struct foo) -> XRESIZEVEC (struct foo, p, num) - obstack_alloc (ob, sizeof (struct foo)) -> XOBNEW (ob, struct foo) - obstack_alloc (ob, num * sizeof (struct foo)) -> XOBNEWVEC (ob, struct foo, num) - alloca (sizeof (struct foo)) -> XALLOCA (struct foo) - alloca (num * sizeof (struct foo)) -> XALLOCAVEC (struct foo, num) Some instances of xmalloc followed by memset to zero the buffer were replaced by XCNEW or XCNEWVEC. I regtested on x86-64, Ubuntu 14.04, but the patch touches many architecture-specific files. For those I'll have to rely on the buildbot or people complaining that I broke their gdb. gdb/ChangeLog: * aarch64-linux-nat.c (aarch64_add_process): Likewise. * aarch64-tdep.c (aarch64_gdbarch_init): Likewise. * ada-exp.y (write_ambiguous_var): Likewise. * ada-lang.c (resolve_subexp): Likewise.

2015-08-07Fix interrupt-noterm.exp on targets always in non-stopPedro Alves1-8/+8

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 ...

2015-07-31Mostly trivial enum fixesSimon Marchi1-9/+14
This is a patch I extracted from Pedro's C++ branch. It contains the most trivial enum fixes, where an integer type/value was used instead of the appropriate enum type/value. It fixes many C++ errors, since in C++ you can't mix integers and enums implicitely. Regardless of the C++ conversion, I think this is a good cleanup to make use of the appropriate enum types. Regression-tested on native x86_64. gdb/ChangeLog: * aarch64-linux-nat.c (aarch64_linux_can_use_hw_breakpoint): Use enum type or value instead of integer. (aarch64_linux_insert_watchpoint): Likewise.
