9 years agoExpand keyword lexing intelligence in the linespec parser.
Keith Seitz [Mon, 23 Mar 2015 19:59:18 +0000 (12:59 -0700)]
Expand keyword lexing intelligence in the linespec parser.

    This patch changes the heuristic the linespec lexer uses to
    detect a keyword in the input stream.

    Currently, the heuristic is: a word is a keyword if it
    1) points to a string that is a keyword
    2) is followed by a non-identifier character

    This is strictly more correct than using whitespace. For example,
    it allows constructs such as "break foo if(i == 1)". However,
    find_condition_and_thread in breakpoint.c does not support this expanded
    usage. It requires whitespace to follow the keyword.

    The proposed new heuristic is: a word is a keyword if it
    1) points to a string that is a keyword
    2) is followed by whitespace
    3) is not followed by another keyword string followed by whitespace

    This additional complexity allows constructs such as
    "break thread thread 3" and "break thread 3".  In the former case,
    the actual location is a symbol named "thread" to be set on thread #3.
    In the later case, the location is NULL, i.e., the default location,
    to be set on thread #3.

    In order to pass all the new tests added here, I've also had to add a
    new feature to parse_breakpoint_sals, which expands recognition of the
    default location to keywords other than "if", which is the only keyword
    currently permitted with the default (NULL) location, but there is no
    reason to exclude other keywords.

    Consequently, it will be possible to use "break thread 1" or
    "break task 1".

    In addition to all of this, it is now possible to remove the keyword_ok
    state from the linespec parser.

    gdb/ChangeLog

     * breakpoint.c (parse_breakpoint_sals): Use
     linespec_lexer_lex_keyword to ascertain if the user specified

In a previous patch for PR 14675, to fix a problem with
the .eh_frame section when static linking, I added a step to
finalize the .eh_frame section at the end of the first link
pass. This patch caused PR 18152, where a plugin-claimed
object caused a non-claimed object's layout to be deferred
until replacement files were read. The call to
finalize_eh_frame_section() is happening before the layout of
the deferred objects, leading to the internal error in
do_relocate_sections.

This patch moves the finalization of the .eh_frame section to
after deferred objects have been processed.

[gdb/DWARF] Introduce linked list for dynamic attributes

This patch introduces a linked list for dynamic attributes of a type.
This is a pre-work for the Fortran dynamic array support. The Fortran
dynamic array support will add more dynamic attributes to a type.
As only a few types will have such dynamic attributes set, a linked
list is more efficient in terms of memory consumption than adding
multiple attributes to main_type.

  RSRL: resuming stopped-resumed LWP LWP 18461 at 0x3b36af4b51: step=0

The first line shows we had just resumed LWP 18465, which does:

 void *
 child_func (void *dummy)
 {
   kill (pid, SIGKILL);
   exit (1);
 }

So if the kernel manages to schedule that thread fast enough, the
process may be killed before GDB has a chance to resume LWP 18461.

GDBserver has code at the tail end of linux_resume_one_lwp to cope
with this:

~~~
    ptrace (step ? PTRACE_SINGLESTEP : PTRACE_CONT, lwpid_of (thread),
    (PTRACE_TYPE_ARG3) 0,
    /* Coerce to a uintptr_t first to avoid potential gcc warning
       of coercing an 8 byte integer to a 4 byte pointer.  */
    (PTRACE_TYPE_ARG4) (uintptr_t) signal);

    current_thread = saved_thread;
    if (errno)
      {
/* ESRCH from ptrace either means that the thread was already
   running (an error) or that it is gone (a race condition).  If
   it's gone, we will get a notification the next time we wait,
   so we can ignore the error.  We could differentiate these
   two, but it's tricky without waiting; the thread still exists
   as a zombie, so sending it signal 0 would succeed.  So just
   ignore ESRCH.  */
if (errno == ESRCH)
  return;

perror_with_name ("ptrace");
      }
~~~

However, that's not a complete fix, because between starting to handle
the resume request and getting that PTRACE_CONTINUE, we run other
ptrace calls that can also fail with ESRCH, and that end up throwing
an error (with perror_with_name).

In the case above, I indeed sometimes see resume_stopped_resumed_lwps
fail in the registers read:

resume_stopped_resumed_lwps (struct lwp_info *lp, void *data)
{
...
      CORE_ADDR pc = regcache_read_pc (regcache);

Or e.g., in 32-bit mode, i386_linux_resume has several calls that can
throw too.

Whether to ignore ptrace errors or not depends on context that is only
available somewhere up the call chain.  So the fix is to let ptrace
errors throw as they do today, and wrap the resume request in a
TRY/CATCH that swallows it iff the lwp that we were trying to resume
is no longer ptrace-stopped.

gdbserver/Linux: unbreak thread event randomization

Wanting to make sure the new continue-pending-status.exp test tests
both cases of threads 2 and 3 reporting an event, I added counters to
the test, to make it FAIL if events for both threads aren't seen.
Assuming a well behaved backend, and given a reasonable number of
iterations, it should PASS.

However, running that against GNU/Linux gdbserver, I found that
surprisingly, that FAILed.  GDBserver always reported the breakpoint
hit for the same thread.

Turns out that I broke gdbserver's thread event randomization
recently, with git commit 582511be ([gdbserver] linux-low.c: better
starvation avoidance, handle non-stop mode too).  In that commit I
missed that the thread structure also has a status_pending_p field...
The end result was that count_events_callback always returns 0, and
then if no thread is stepping, select_event_lwp always returns the
event thread.  IOW, no randomization is happening at all.  Quite
curious how all the other changes in that patch were sufficient to fix
non-stop-fair-events.exp anyway even with that broken.

20, I get:

 Running /home/pedro/gdb/mygit/src/gdb/testsuite/gdb.base/disp-step-syscall.exp ...

 FAIL: gdb.base/disp-step-syscall.exp: vfork: continue to marker (vfork) (the program is no longer running)

And with --target=native-gdbserver, I get:

 Running /home/pedro/gdb/mygit/src/gdb/testsuite/gdb.base/disp-step-syscall.exp ...
 KPASS: gdb.base/disp-step-syscall.exp: vfork: single step over vfork (PRMS server/13796)

 FAIL: gdb.base/disp-step-syscall.exp: vfork: continue to marker (vfork) (the program is no longer running)

First, the lack of fork support on remote targets is supposed to be
kfailed, so the KPASS is obviously bogus.  The extended-remote board
should have KFAILed too.

The problem is that the test is using "is_remote" instead of
gdb_is_target_remote.

And then, I get:

 (gdb) PASS: gdb.base/disp-step-syscall.exp: vfork: set displaced-stepping on
 stepi

 Program terminated with signal SIGSEGV, Segmentation fault.
 The program no longer exists.
 (gdb) PASS: gdb.base/disp-step-syscall.exp: vfork: single step over vfork

Obviously, that should be a FAIL.  The problem is that the test only
expects SIGILL, not SIGSEGV.  It also doesn't bail correctly if an
internal error or some other pattern caught by gdb_test_multiple
matches.  The test doesn't really need to match specific exits/crashes
patterns, if the PASS regex is improved, like in ...

... this and the other "stepi" tests are a bit too lax, passing on
".*".  This tightens those up to expect "x/i" and the "=>" current PC
indicator, like in:

 1: x/i $pc
 => 0x3b36abc9e2 <vfork+34>:     syscall

On x86_64 Fedora 20, I now get a quick KFAIL instead of timeouts with
both the native-extended-gdbserver and native-gdbserver boards:

 PASS: gdb.base/disp-step-syscall.exp: vfork: delete break vfork

 KFAIL: gdb.base/disp-step-syscall.exp: vfork: single step over vfork (PRMS: server/13796)

implement gdbarch method get_syscall_number for aarch64-linux,
and add aarch64-linux.xml file, which looks straightforward, however
the changes to test case doesn't.

First of all, we enable catch-syscall.exp on aarch64-linux target,
but skip the multi_arch testing on current stage.  I plan to touch
multi arch debugging on aarch64-linux later.

Then, when I run catch-syscall.exp on aarch64-linux, gcc errors that
SYS_pipe isn't defined.  We find that aarch64 kernel only has pipe2
syscall and libc already convert pipe to pipe2.  As a result, I change
catch-syscall.c to use SYS_pipe if it is defined, otherwise use
SYS_pipe2 instead.  The vector all_syscalls in catch-syscall.exp can't
be pre-determined, so I add a new proc setup_all_syscalls to fill it,
according to the availability of SYS_pipe.

Regression tested on {x86_64, aarch64}-linux x {native, gdbserver}.

9 years agoFetch all registers before writing the core register notes.

Fetch all registers before writing the core register notes.

Without this, not all registers were present in the core generated by
gcore.  For example, running 'gcore' on a program without examining
the vector registers (SSE or AVX) would store all the vector registers
as zeros because they were not pulled into the regcache.  Running
'info vector' before 'gcore' would store the correct values in the
core since it populated the regcache.  For Linux processes, a similar
operation is achieved by having the thread iterator callback invoke
target_fetch_registers on each thread before its corresponding
register notes are dumped.
