2016-08-09Fix PR gdb/20418 - Problems with synchronous commands and new-uiPedro Alves11-30/+238
When executing commands on a secondary UI running the MI interpreter, some commands that should be synchronous are not. MI incorrectly continues processing input right after the synchronous command is sent, before the target stops. The problem happens when we emit MI async events (=library-loaded, etc.), and we go about restoring the previous terminal state, we end up calling target_terminal_ours, which incorrectly always installs the current UI's input_fd in the event loop... That is, code like this: old_chain = make_cleanup_restore_target_terminal (); target_terminal_ours_for_output (); fprintf_unfiltered (mi->event_channel, "library-loaded"); ... do_cleanups (old_chain); The fix is to move the add_file_handler/delete_file_handler calls out of target_terminal_$foo, making these completely no-ops unless called with the main UI as current UI. gdb/ChangeLog: 2016-08-09 Pedro Alves <palves@redhat.com> PR gdb/20418 * event-top.c (ui_register_input_event_handler) (ui_unregister_input_event_handler): New functions.

2016-08-09Fix PR mi/20431 - Missing MI prompts after sync execution MI command ↵Pedro Alves4-0/+98
(-exec-continue, etc.) errors gdb 7.11 introduced an MI regression: a failing MI sync execution command misses printing the MI prompt, and then all subsequent command miss it too: $ gdb-7.11.1 -i=mi [...] p 1 &"p 1\n" ~"$1 = 1" ~"\n" ^done (gdb) <<< prompted ok -exec-continue ^error,msg="The program is not being run." <<< missing prompt after this print 1 &"print 1\n" ~"$2 = 1" ~"\n" ^done <<< missing prompt after this gdb 7.10.1 behaved correctly, even with "set mi-async on": -exec-continue ^error,msg="The program is not being run."

It used to work because before that patch, we happened to skip disabling stdin if the current target didn't do async (which it never does before execution). I was surprised to find that this bug isn't caught by the testsuite, so I made a thorough test that tests all combinations of pairs of: - a failing synchronous execution command - a failing non-execution command - a non-failing command gdb/ChangeLog: 2016-08-09 Pedro Alves <palves@redhat.com> PR mi/20431 * mi/mi-main.c (mi_execute_command): Enable input and set prompt state to PROMPT_NEEDED. gdb/testsuite/ChangeLog: 2016-08-09 Pedro Alves <palves@redhat.com> PR mi/20431 * gdb.mi/mi-cmd-error.exp: New file.
2016-08-09Fix PR gdb/18653: gdb disturbs inferior's inherited signal dispositionsPedro Alves18-7/+386
gdb's (or gdbserver's) own signal handling should not interfere with the signal dispositions their spawned children inherit. However, it currently does. For example, some paths in gdb cause SIGPIPE to be set to SIG_IGN, and as consequence, the child starts with SIGPIPE to set to SIG_IGN too, even though gdb was started with SIGPIPE set to SIG_DFL. This is because the exec family of functions does not reset the signal disposition of signals that are set to SIG_IGN: http://pubs.opengroup.org/onlinepubs/7908799/xsh/execve.html Signals set to the default action (SIG_DFL) in the calling process image are set to the default action in the new process image. Signals set to be ignored (SIG_IGN) by the calling process image are set to be ignored by the new process image. Signals set to be caught by the calling process image are set to the default action in the new process image (see <signal.h>). And neither does it reset signal masks or flags. In order to be transparent, when spawning new child processes to debug (with "run", etc.), reset signal actions and mask back to what was originally inherited from gdb/gdbserver's parent, just before execing the target program to debug. gdb/ChangeLog: 2016-08-09 Pedro Alves <palves@redhat.com> PR gdb/18653 * Makefile.in (SFILES): Add common/signals-state-save-restore.c.

Nowadays, we are using some entries AT_PHENT and AT_HWCAP in auxv to determine whether the process is a 32-bit arm one or 64-bit aarch64 one, and get the right gdbarch. However, in the process of parsing auxv (in inf_ptrace_auxv_parse), the size of int and data pointer of target_gdbarch is used. If debug program exists (in most of cases), target_gdbarch is already set according to the debug program, which is arm in my case. Then, GDB can parse auxv successfully. However, in gdb.base/attach-pie-noexec.exp, the debug program is removed, target_gdbarch is aarch64 when GDB parse auxv, so GDB can't parse it successfully. Instead of using auxv, we check the return value of ptrace NT_ARM_VFP. If the program is an arm process, NT_ARM_VFP is OK, otherwise, error is returned.
