Subject: [rfc patch] nomem: internal_error -> error
Hi,
unfortunately I see this problem reproducible only with the
archer-jankratochvil-vla branch (VLA = Variable Length Arrays - char[var]).
OTOH this branch I hopefully submit in some form for FSF GDB later.
In this case (a general problem but tested for example on Fedora 13 i686):
int
main (int argc, char **argv)
{
char a[argc];
return a[0];
}
(gdb) start
(gdb) print a
../../gdb/utils.c:1251: internal-error: virtual memory exhausted: can't allocate 4294951689 bytes.
It is apparently because boundary for the variable `a' is not initialized
there. Users notice it due to Eclipse-CDT trying to automatically display all
the local variables on each step.
Apparentl no regressions on {x86_64,x86_64-m32,i686}-fedora13-linux-gnu.
But is anone aware of the reasons to use internal_error there?
I find simple error as a perfectly reasonable there.
(history only tracks it since the initial import)
IIRC this idea has been discussed with Tom Tromey, not sure of its origin.
I understand it may be offtopic for FSF GDB but from some GDB crashes I am not
sure if it can happen only due to the VLA variables.
Thanks,
Jan

Subject: [patch 3/4]#3 linux-nat: Do not respawn signals
Hi,
linux-nat.c is fixed to never respawn signals; possibly keeping SIGSTOP
pending, as is done in current in FSF gdbserver and as suggested by Pedro:
http://sourceware.org/ml/gdb-patches/2010-08/msg00544.html
The last linux-nat.c removed patch chunk comes from the initial implementation
by Mark Kettenis:
[PATCH] New Linux threads support
http://sourceware.org/ml/gdb-patches/2000-09/msg00020.html
92280a75e017683bf8e4f339f4f85640b0700509
It gets in part reimplemented into the new stop_wait_callback <if (lp->step)>
part and partially just not needed as currently GDB never drops the signals as
it does not PTRACE_CONT the thread; signal is kept for processing:
"RC: Not resuming sibling %s (has pending)\n"
In stop_wait_callback I believe breakpoints cancellation is not needed here,
it would be done later.
The testcase sigstep-threads.exp was written to catch a regression-like
appearance then the new <if (lp->step)> part of stop_wait_callback gets
removed. Still the tecase fails even with FSF HEAD:
32 var++; /* step-1 */
(gdb) step
Program received signal SIGUSR1, User defined signal 1.
Program received signal SIGUSR1, User defined signal 1.
31 { /* step-0 */
There is no reason why it shouldn't stop on line 33, between line 32 and line
33 no signal would occur. Stepping of the current thread should not be
affected by whatever happens in the other threads as select_event_lwp has:
/* Give preference to any LWP that is being single-stepped. */
There is a problem that with FSF HEAD GDB does PTRACE_SINGLESTEP for thread A,
PTRACE_CONT for thread B (because of set scheduler-locking off), thread B hits
SIGUSR1, so GDB tkills thread A with SIGSTOP and it can receive SIGSTOP for
thread A before the SIGTRAP for completed PTRACE_SINGLESTEP. At that moment
select_event_lwp. forgets it was stepping thread A because there is no pending
SIGTRAP event. currently_stepping still remembers thread A was stepping so it
will later stop but as thread A was PTRACE_CONT-ed in the meantime it is too
late.
There is the new <if (lp->step)> part of stop_wait_callback to always track
thread A is stepping. Due to different scheduling without this part the
changed GDB would very rarely stop in this testcase otherwise, making it look
as a regression.
I have some another patch I may post separately as if multiple signals happen
besides SIGTRAP GDB still may switch from thread A away (as not considering it
stepping) to thread B for SIGUSR and accidentally PTRACE_CONT thread A.
But I do not find this as a prerequisite for this patchset.
Thanks,
Jan

* linux-nat.c (stop_wait_callback): New gdb_assert. Remove signals
respawning; keep TP with SIGNALLED. New debugging message "SWC:
Delayed SIGSTOP caught for %s.". Catch next signal if SIGSTOP has
been caught and LP->STEP is set.
(linux_nat_wait_1) <lp && lp->signalled>: Remove.

Subject: [patch 4/4]#3 Remove redundant lp->siginfo
Hi,
this is a simplification which should not affect GDB behavior. As linux-nat
now stops on each received signal without any reordering of them then
PTRACE_GETSIGINFO is enough to access siginfo, without any need to copy it in
advance.
Thanks,
Jan
gdb/
2010-09-20 Jan Kratochvil <jan.kratochvil@redhat.com>
* linux-nat.c (resume_callback) <lp->stopped && lp->status == 0>
(linux_nat_resume): Remove LP->SIGINFO clearing.
(save_siginfo): Remove.
(stop_wait_callback) <WSTOPSIG (status) != SIGSTOP>
(linux_nat_filter_event) <linux_nat_status_is_event (status)>: Remove
the save_siginfo call.
(resume_stopped_resumed_lwps): Remove LP->SIGINFO clearing.
(linux_nat_set_siginfo_fixup): Use PTRACE_GETSIGINFO.
* linux-nat.h (struct lwp_info) <siginfo>: Remove.

Subject: [patch] Fix infinite loop crash on self-referencing class
Hi,
class C { static C s; }; is a problem for GDB as it references itself and it
can crash. Downstream Bug:
https://bugzilla.redhat.com/show_bug.cgi?id=627432
#3 0x00000000005b2cc5 in gnuv3_pass_by_reference (type=0x1044d3c8) at ../../gdb/gnu-v3-abi.c:840
#4 0x00000000005b2cc5 in gnuv3_pass_by_reference (type=0x1044d3c8) at ../../gdb/gnu-v3-abi.c:840
[...]
No regressions on {x86_64,x86_64-m32,i686}-fedora13-linux-gnu.
FYI the .cc file is not reproducible on - and only on - Fedora 14 GCC, filed:
https://bugzilla.redhat.com/show_bug.cgi?id=637315
I would even check it in in some time.
Thanks,
Jan

Subject: [patch] .gdb_index: Do not crash on NOBITS
Hi,
elfutils-0.148 still do not contain patch of its GIT
804e9ca4d644e64a6125307cbf0a0b89477d7611 where the .gdb_index section has been
also split into the separate debug info file.
Due to it binaries split using elfutils-0.148 contain
[38] .gdb_index NOBITS 0000000000000000 0000338c
instead of expected
[28] .gdb_index PROGBITS 0000000000000000 0000211c
and due to it GDB while reading the file can error() by:
Reading symbols from x.debug...Dwarf Error: Can't read DWARF data from 'x.debug'
which should not be fatal but due to some other bugs therein it can crash GDB.
The wrong separate debug info file is for example:
http://kojipkgs.fedoraproject.org/packages/glibc/2.12.90/10/x86_64/glibc-debuginfo-2.12.90-10.x86_64.rpm
/usr/lib/debug/lib64/libutil-2.12.90.so.debug
OK to check-in?
It does not attempt to use .gdb_index from the main binary, it will just
disable .gdb_index usage on these binaries.
Thanks,
Jan

Hi,
currently if you attach to or load a core file for executable, its -gdb.py
script is loaded. But none -gdb.py for the shared libraries.
Spawned or with the fix (libstdc++-gdb.py):
#1 0x00000000004007b5 in f (s="a") at 1.C:4
^ is std::string
Attached/core without the fix:
#1 0x00000000004007b5 in f (s=...) at 1.C:4
No regressions on {x86_64,x86_64-m32,i686}-fedora13-linux-gnu.
Mostly obvious, I will check it in later.

That is from:
#0 in elf_slurp_reloc_table_from_section (abfd, asect, rel_hdr, reloc_count=1170, relents, symbols, dynamic=1) at elfcode.h:1482
#1 in bfd_elf64_slurp_reloc_table (abfd, asect, symbols, dynamic=1) at elfcode.h:1563
#2 in _bfd_elf_get_synthetic_symtab (abfd, symcount=0, syms, dynsymcount=1792, dynsyms, ret) at elf.c:9269
#3 in elf_symfile_read (objfile, symfile_flags=6) at elfread.c:809
Where
elfcode.h:elf_slurp_reloc_table_from_section
contains
ps = symbols + ELF_R_SYM (rela.r_info) - 1;
relent->sym_ptr_ptr = ps;
`symbols' here is elf_symfile_read's `dyn_symbol_table'. `dyn_symbol_table'
got immediately xfree'd but the freed memory remained referenced by
asect->relocation (containing the RELENT memory above, stored there by
elf_slurp_reloc_table).
asect->relocation probably does not get used if ABFD is not being read-in the
second time, which happens only if OBJFILE is being created the second time,
which happens due to the error call in the previous mail.
I was curious there elf_symfile_read uses 0 for COPY_NAMES in a similar case:
elf_symtab_read (objfile, ST_REGULAR, symcount, symbol_table, 0);
where SYMBOL_TABLE is also immediately xfreed. But that seems to be correct as
elf_slurp_symbol_table uses
symbase = (elf_symbol_type *) bfd_zalloc (abfd, amt);
for the content where later elfread.c's SYMBOL_TABLE points to. Only the
pointers get xfreed which is OK.
No regressions on {x86_64,x86_64-m32,i686}-fedora14snapshot-linux-gnu.

Subject: [new testcase] Regression 7.1->7.2 for iFort [Re: [RFA-v2] dwarf debug format: Support DW_AT_variable_parameter attribute]

* dwarf2read.c (new_symbol): Handle DW_AT_variable_parameter
attribute.
Please revert this patch.

changes the data structures meaning in any way. It just states which data can
be modified by whom. I do not think this is useful for GDB in any way.

I believe the Pascal compiler should generate different debug info. For the
`var' keyword you can either (a) use DW_TAG_reference_type and point
DW_AT_location at the pointer or (b) use DW_OP_deref (as iFort does) on the
passed pointer and point DW_AT_location at the value itself.
DW_AT_variable_parameter would be true only for the (a) choice.
1 subroutine f (i)
2 integer i
3 i = 2
4 end
5 program varparam
6 integer m
7 m = 1
8 call f (m)
9 write(*,*) m
10 end
for iFort 11.1 20100806 it regressed this code, GDB-7.1 displayed:
Breakpoint 1, f (i=1) at varparam.f90:3
3 i = 2
(gdb) p i
$1 = 1
while GDB-7.2 displays:
Breakpoint 2, f (i=@0x1) at varparam.f90:3
3 i = 2
(gdb) p i
$1 = (REF TO -> ( INTEGER(4) )) @0x1: <error reading variable>
(note that `0x1' GDB considers as an address here)
A new testcase for the iFort usage case is attached.
No regressions on {x86_64,x86_64-m32,i686}-fedora14snapshot-linux-gnu.
I will then check-in the testcase or you can or so.

iFort (Intel Fortran compiler) produces DIEs like:
<1><1dc>: Abbrev Number: 6 (DW_TAG_module)
<1e0> DW_AT_name : MOD1
But Fortran is case insensitive, therefore GDB lowercases any user input
first. Symbols cannot match. gfortran always produces lowercased DIE names.
I was told by Jakub Jelinek GCC frontend will never be properly case
preserving - to output "Mod1" if user stated it in such case in the sources.
Therefore GDB will now lowercase any case insensitive symbol names on their
read-in from DWARF.
ELF symbol tables are currently not touched - their matching to their CU (and
thus to their DW_AT_identifier_case / DW_AT_language) is expensive and it does
not seem to me to be needed for iFort as only the module names are uppercased
there.
For the iFort compatibility there is also needed:
[new testcase] Regression 7.1->7.2 for iFort [Re: [RFA-v2] dwarf debug format: Support DW_AT_variable_parameter attribute]
http://sourceware.org/ml/gdb-patches/2010-11/msg00084.html
No regressions on {x86_64,x86_64-m32,i686}-fedora14snapshot-linux-gnu.

Jan

I understand this hack is not nice, the correct way would be to unify more

Subject: [patch] .gdb_index: Fix Ada regression
Hi,
on a system with libraries using .gdb_index all the Ada testcases FAIL:
Running ./gdb.ada/print_pc.exp ...
FAIL: gdb.ada/print_pc.exp: start inferior (GDB internal error)
FAIL: gdb.ada/print_pc.exp: p /x $pc
dwarf2read.c:2374: internal-error: map_ada_symtabs called via index method
FAIl is on Fedora 14 snapshot using gcc-debuginfo-4.5.1-3.fc14.x86_64 file:
/usr/lib/debug/lib64/libgcc_s-4.5.1-20100907.so.1.debug
The regressions get fixed on x86_64-fedora14snapshot-linux-gnu by the attached
patch. No regressions on {x86_64,x86_64-m32,i686}-fedora14snapshot-linux-gnu.
During my tests with `set language ada' I could not lookup non-Ada symbols
anyway so I believe the patch is OK but sure it needs an Ada-wise review.
Thanks,
Jan

This comment is right, Python has no bug there, other gdb/python/ code has
bugs. That is some gdb/python/ code returned success value while still
leaving the python exception set. Such case is undefined and unchecked by
Python. Python error state does not follow the errno POSIX semantics
The setting of errno after a successful call to a function is
unspecified [...].
as Python requires instead:
The Python error state after a successful call to a function must be
cleared.
I have checked callers of these functions, as a closure on the callers of the
top py-utils.c functions. That does not mean this Python error state handling
verification is complete:
python_string_to_unicode unicode_to_encoded_string
unicode_to_encoded_python_string unicode_to_target_string
unicode_to_target_python_string python_string_to_target_string
python_string_to_target_python_string python_string_to_host_string

Therefore I have removed the check after PyRun_SimpleFile.
