2015-01-31Add max-completions parameter, and implement tab-completion limiting.Gary Benson1-0/+6
This commit adds a new exception, MAX_COMPLETIONS_REACHED_ERROR, to be thrown whenever the completer has generated too many candidates to be useful. A new user-settable variable, "max_completions", is added to control this behaviour. A top-level completion limit is added to complete_line_internal, as the final check to ensure the user never sees too many completions. An additional limit is added to default_make_symbol_completion_list_break_on, to halt time-consuming symbol table expansions. gdb/ChangeLog: PR cli/9007 PR cli/11920 PR cli/15548 * cli/cli-cmds.c (complete_command): Notify user if max-completions reached. * common/common-exceptions.h (enum errors) <MAX_COMPLETIONS_REACHED_ERROR>: New value. * completer.h (get_max_completions_reached_message): New declaration.

2015-01-15Move code to disable ASR to nat/Sergio Durigan Junior1-0/+1
This patch moves the shared code present on gdb/linux-nat.c:linux_nat_create_inferior and gdb/gdbserver/linux-low.c:linux_create_inferior to nat/linux-personality.c. This code is responsible for disabling address space randomization based on user setting, and using <sys/personality.h> to do that. I decided to put the prototype of the maybe_disable_address_space_randomization on nat/linux-osdata.h because it seemed the best place to put it. I regression-tested this patch on Fedora 20 x86_64, and found no regressions. gdb/ChangeLog 2015-01-15 Sergio Durigan Junior <sergiodj@redhat.com> * Makefile.in (HFILES_NO_SRCDIR): Add nat/linux-personality.h.

2014-11-21Include alloca.h unconditionallyYao Qi1-0/+1
Since gnulib alloca module was imported, we can include alloca.h in both gdb and gdbserver unconditionally, so this patch adds inclusion of alloca.h in common-defs.h. This patch also removes AC_FUNC_ALLOCA in configure.ac because we don't need to check alloca any more. This patch below is removed in fact. [RFA/commit] include alloca.h if available. https://www.sourceware.org/ml/gdb-patches/2010-08/msg00566.html Since alloca.h is from gnulib now, we don't have to check malloc.h in configure and include malloc.h in code. This patch also remove them too. gdb: 2014-11-21 Yao Qi <yao@codesourcery.com> * common/common-defs.h: Include alloca.h * configure.ac: Don't invoke AC_FUNC_ALLOCA. * configure: Re-generated. * defs.h: Remove code handling alloca. * utils.c (gdb_realpath): Don't check HAVE_ALLOCA is defined or not. gdb/gdbserver: 2014-11-21 Yao Qi <yao@codesourcery.com> * configure.ac: Don't invoke AC_FUNC_ALLOCA. (AC_CHECK_HEADERS): Remove malloc.h. * configure: Re-generated. * config.in: Re-generated. * server.h: Don't include alloca.h and malloc.h. * gdbreplay.c: Don't check HAVE_ALLOCA_H is defined. Don't include malloc.h.
2014-11-14common-defs.h: include <stdarg.h> before <stdio.h>Joel Brobecker1-1/+1
When trying to build gdbserver on ppc-lynx178, the compiler reports while trying to compile gdbserver/ax.c that vsprintf is not declared. Looking at my C99 reference manual (a draft), I see the following synopsis: #include <stdarg.h> #include <stdio.h> int vsprintf(char * restrict s, [etc]); Looking at stdio.h on LynxOS-178, if found where vsprintf gets declared: #if defined(__varargs_h) || defined(__stdarg_h) \ || defined(_VARARGS_H) || defined(_STDARG_H) extern int vsprintf _AP((char *, const char *, va_list)); #endif Digging further, I noticed that common-defs.h, which is included via server.h, includes stdarg.h after including stdio, explaining why vsprintf does not get declared in this case. This patch fixes the problem by including stdarg.h before stdio.h. gdb/ChangeLog: * common/common-defs.h: Move <stdarg.h> #include ahead of <stdio.h> #include. Tested on x86_64-linux.

2014-09-12Include common-defs.h instead of defs.h/server.h in shared codeGary Benson14-77/+14
This commit makes 19 of the 22 shared .c files in common, nat and target include common-defs.h instead of defs.h/server.h.

2014-09-12Introduce common-regcache.hGary Benson1-0/+36
This introduces common-regcache.h. This contains two functions that allow nat/linux-btrace.c to be simplified. A better long term solution would be unify the regcache code, but this is sufficient for now. gdb/ChangeLog: * common/common-regcache.h: New file. * Makefile.in (HFILES_NO_SRCDIR): Add common/common-regcache.h. * regcache.h: Include common-regcache.h.

2014-09-11Introduce target_{stop,continue}_ptidGary Benson1-35/+2
This commit introduces two new functions to stop and restart target processes that shared code can use and that clients must implement. It also changes some shared code to use these functions. gdb/ChangeLog: * target/target.h (target_stop_ptid, target_continue_ptid): Declare. * target.c (target_stop_ptid, target_continue_ptid): New functions. * common/agent.c [!GDBSERVER]: Don't include infrun.h.

2014-09-11Introduce target/target.hGary Benson1-44/+8
This introduces target/target.h. This file declares some functions that the shared code can use and that clients must implement.

2014-09-11Introduce show_debug_regsGary Benson2-0/+9
This commit adds a new global flag show_debug_regs to common-debug.h to replace the flag debug_hw_points used by gdbserver and by the Linux x86 and AArch64 ports, and to replace the flag maint_show_dr used by the Linux MIPS port. Note that some debug printing in the AArch64 port was enabled only if debug_hw_points > 1 but no way to set debug_hw_points to values other than 0 and 1 was provided; that code was effectively dead. This commit enables all debug printing if show_debug_regs is nonzero, so the AArch64 output will be more verbose than previously. gdb/ChangeLog: * common/common-debug.h (show_debug_regs): Declare. * common/common-debug.c (show_debug_regs): Define. * aarch64-linux-nat.c (debug_hw_points): Don't define. Replace all uses with show_debug_regs. Replace all uses that considered debug_hw_points as a multi-value integer with straight boolean uses. * x86-nat.c (debug_hw_points): Don't define. Replace all uses with show_debug_regs. * nat/x86-dregs.c (debug_hw_points): Don't declare. Replace all uses with show_debug_regs. * mips-linux-nat.c (maint_show_dr): Don't define. Replace all uses with show_debug_regs. gdb/gdbserver/ChangeLog: * server.h (debug_hw_points): Don't declare. * server.c (debug_hw_points): Don't define.

2014-09-02Rename 32- and 64-bit Intel files from "i386" to "x86"Gary Benson2-67/+67
This commit renames nine files that contain code used by both 32- and 64-bit Intel ports such that their names are prefixed with "x86" rather than "i386". All types, functions and variables within these files are likewise renamed such that their names are prefixed with "x86" rather than "i386". This makes GDB follow the convention used by gdbserver such that 32-bit Intel code lives in files called "i386-*", 64-bit Intel code lives in files called "amd64-*", and code for both 32- and 64-bit Intel lives in files called "x86-*". This commit only renames OS-independent files. The Linux ports of both GDB and gdbserver now follow the i386/amd64/x86 convention fully. Some ports still use the old convention where "i386" in file/function/ type/variable names can mean "32-bit only" or "32- and 64-bit" but I don't want to touch ports I can't fully test except where absolutely necessary. gdb/ChangeLog: * i386-nat.h: Renamed as... * x86-nat.h: New file.

This commit moves cleanups.[ch] into gdb/common/. The only change to the content of the files is that cleanups.c's include list was altered to match its new location. gdb/ChangeLog: * cleanups.h: Moved to... * common/cleanups.h: New file. * cleanups.c: Moved to... * common/cleanups.c: New file.

2014-08-19Introduce common-debug.hGary Benson4-9/+89
This introduces common-debug.h. This holds the functions debug_printf and debug_vprintf, two functions that the common code can use to print debugging messages. Clients of the common code are expected to implement debug_vprintf; a debug_vprintf function is written from scratch for GDB, and gdbserver's existing debug_printf is repurposed as debug_vprintf. common/agent.c is changed to use debug_vprintf rather than defining the macro DEBUG_AGENT depending on GDBSERVER. nat/i386-dregs.c is changed to use the externally-implemented debug_printf, rather than defining it itself. gdb/ChangeLog: * common/common-debug.h: New file. * common/common-debug.c: Likewise. * debug.c: Likewise. * Makefile.in (SFILES): Add common/common-debug.c.

2014-08-19Move print-utils.h to common-defs.hGary Benson1-0/+1
This commit moves the inclusion of print-utils.h to common-defs.h and removes all other inclusions. gdb/ChangeLog: * common/common-defs.h: Include print-utils.h. * utils.h: Do not include print-utils.h. gdb/gdbserver/ChangeLog: * utils.h: Do not include print-utils.h.
2014-08-19Introduce common-types.hGary Benson2-0/+62
This introduces common-types.h. This file defines various standard types used by gdb and gdbserver. Currently these types are conditionally defined based on GDBSERVER. The long term goal is to remove all such tests; however, this is difficult as currently gdb uses definitions from BFD. In the meantime this is still a step in the right direction. gdb/ChangeLog: * common/common-types.h: New file. * Makefile.in (HFILES_NO_SRCDIR): Add common/common-types.h. * common/common-defs.h: Include common-types.h. * defs.h (gdb_byte, CORE_ADDR, CORE_ADDR_MAX, LONGEST) (ULONGEST): Remove. gdb/gdbserver/ChangeLog: * server.h: Add static assertion. (gdb_byte, CORE_ADDR, LONGEST, ULONGEST): Remove.
2014-08-19Introduce common/errors.hGary Benson4-4/+137
This introduces common/errors.h. This holds some error- and warning- related declarations that can be used by the code in common, nat and target. Some of the declared functions must be provided by the client as documented by the header file comments. gdb/ChangeLog: * common/errors.h: New file. * common/errors.c: Likewise. * Makefile.in (SFILES): Add common/errors.c. (HFILES_NO_SRCDIR): Add common/errors.h. (COMMON_OBS): Add errors.o. (errors.o): New rule. * common/common-defs.h: Include errors.h. * utils.h (perror_with_name, error, verror, warning, vwarning): Don't declare. * common/common-utils.h: (malloc_failure, internal_error): Likewise. gdb/gdbserver/ChangeLog: * Makefile.in (SFILES): Add common/errors.c. (OBS): Add errors.o. (IPA_OBS): Add errors-ipa.o. (errors.o): New rule.

2014-08-07Move errno.h to common-defs.hGary Benson1-0/+1
This commit moves the inclusion of errno.h to common-defs.h and removes all other inclusions. Note that prior to this commit server.h included errno.h protected by "#ifdef HAVE_ERRNO_H". This protection was added with the Windows CE port, which is currently broken. Since no other platform needs this, I have removed the protection and the configury to support it. gdb/ 2014-08-07 Gary Benson <gbenson@redhat.com> * common/common-defs.h: Include errno.h. * defs.h: Do not include errno.h. * ada-typeprint.c: Likewise. * c-typeprint.c: Likewise. * core-regset.c: Likewise. * corefile.c: Likewise. * corelow.c: Likewise. * event-loop.c: Likewise. * f-typeprint.c: Likewise. * gnu-nat.c: Likewise. * go32-nat.c: Likewise. * i386gnu-nat.c: Likewise. * m2-typeprint.c: Likewise. * nat/linux-btrace.c: Likewise. * p-typeprint.c: Likewise. * procfs.c: Likewise. * remote-sim.c: Likewise. * rs6000-nat.c: Likewise. * target.c: Likewise. * typeprint.c: Likewise. * ui-file.c: Likewise. * valops.c: Likewise. * valprint.c: Likewise. gdb/gdbserver/ 2014-08-07 Gary Benson <gbenson@redhat.com> * configure.ac (AC_CHECK_HEADERS): Remove errno.h. * configure: Regenerate. * config.in: Likewise. * server.h: Do not include errno.h. * event-loop.c: Likewise. * hostio-errno.c: Likewise. * linux-low.c: Likewise. * remote-utils.c: Likewise. * spu-low.c: Likewise. * utils.c: Likewise. * gdbreplay.c: Unconditionally include errno.h.

2014-07-30Introduce common/common-defs.hGary Benson1-0/+30
This commit creates a new header, common/common-defs.h, to hold definitions common to all code under gdb/. Both gdb/defs.h and gdb/gdbserver/server.h are modified to include common-defs.h as their first non-comment line; all code under gdb/ includes either defs.h or server.h as appropriate, so common-defs.h will be the first actual code the compiler sees. For this initial commit common-defs.h includes only the two config.h files. Future commits will move more code currently duplicated across defs.h and server.h such that shared code in gdb/{common,target,nat} can be modified to include common-defs.h rather than defs.h or server.h. gdb/ 2014-07-30 Gary Benson <gbenson@redhat.com> * common/common-defs.h: New file. * Makefile.in (HFILES_NO_SRCDIR): Add common/common-defs.h. * defs.h: Include common-defs.h.

2014-06-08Fix gdb.base/watch-vfork.exp: Watchpoint triggers after vfork (sw) (timeout) ↵Hui Zhu2-0/+10
with Linux 2.6.32 and older version https://sourceware.org/ml/gdb-patches/2014-04/msg00047.html Got gdb.base/watch-vfork.exp: Watchpoint triggers after vfork (sw) (timeout) with Linux 2.6.32 and older version. The rootcause is after the test use "set can-use-hw-watchpoints 0" let GDB doesn't use hardware breakpoint and set a watchpoint on "global", GDB continue will keep single step inside function "vfork". The Linux 2.6.32 and older version doesn't have commit 6580807da14c423f0d0a708108e6df6ebc8bc83d (get more info please goto http://git.kernel.org/cgit/linux/kernel/git/stable/linux-stable.git/commit/?id=6580807da14c423f0d0a708108e6df6ebc8bc83d). When the function "vfork" do syscall, the single step flag TIF_SINGLESTEP will copy to child process. Then GDB detach it, child process and parent process will be hanged. So I make a patch that do a single step before detach. Then TIF_SINGLESTEP of child process in old Linux kernel will be cleared before detach. Child process in new Linux kernel will not be affected by this single step. 2014-06-08 Hui Zhu <hui@codesourcery.com> * common/linux-ptrace.c (linux_disable_event_reporting): New function. * common/linux-ptrace.h (linux_disable_event_reporting): New declaration. * linux-nat.c (linux_child_follow_fork): Do a single step before detach.

2014-04-25PR server/16255: gdbserver cannot attach to a second inferior that is ↵Pedro Alves2-9/+9
multi-threaded. On Linux, we need to explicitly ptrace attach to all lwps of a process. Because GDB might not be connected yet when an attach is requested, and thus it may not be possible to activate thread_db, as that requires access to symbols (IOW, gdbserver --attach), a while ago we make linux_attach loop over the lwps as listed by /proc/PID/task to find the lwps to attach to. linux_attach_lwp_1 has: ... if (initial) /* If lwp is the tgid, we handle adding existing threads later. Otherwise we just add lwp without bothering about any other threads. */ ptid = ptid_build (lwpid, lwpid, 0); else { /* Note that extracting the pid from the current inferior is safe, since we're always called in the context of the same process as this new thread. */ int pid = pid_of (current_inferior); ptid = ptid_build (pid, lwpid, 0); } That "safe" comment referred to linux_attach_lwp being called by thread-db.c. But this was clearly missed when a new call to linux_attach_lwp_1 was added to linux_attach. As a result, current_inferior will be set to some random process, and non-initial lwps of the second inferior get assigned the pid of the wrong inferior. E.g., in the case of attaching to two inferiors, for the second inferior (and so on), non-initial lwps of the second inferior get assigned the pid of the first inferior. This doesn't trigger on the first inferior, when current_inferior is NULL, add_thread switches the current inferior to the newly added thread. Rather than making linux_attach switch current_inferior temporarily (thus avoiding further reliance on global state), or making linux_attach_lwp_1 get the tgid from /proc, which add extra syscalls, and will be wrong in case of the user having originally attached directly to a non-tgid lwp, and then that lwp spawning new clones (the ptid.pid field of further new clones should be the same as the original lwp's pid, which is not the tgid), we note that callers of linux_attach_lwp/linux_attach_lwp_1 always have the right pid handy already, so they can pass it down along with the lwpid. The only other reason for the "initial" parameter is to error out instead of warn in case of attach failure, when we're first attaching to a process. There are only three callers of linux_attach_lwp/linux_attach_lwp_1, and each wants to print a different warn/error string, so we can just move the error/warn out of linux_attach_lwp_1 to the callers, thus getting rid of the "initial" parameter. There really nothing gdbserver-specific about attaching to two threaded processes, so this adds a new test under gdb.multi/. The test passes cleanly against the native GNU/Linux target, but fails/triggers the bug against GDBserver (before the patch), with the native-extended-remote board (as plain remote doesn't support multi-process).
