Port to GDB-6.8pre. |
||||
|
||||
currently for trivial nonthreaded helloworld with no debug info up to -ggdb2 you |
||||
will get: |
||||
(gdb) p errno |
||||
[some error] |
||||
|
||||
* with -ggdb2 and less "errno" in fact does not exist anywhere as it was |
||||
compiled to "(*__errno_location ())" and the macro definition is not present. |
||||
Unfortunately gdb will find the TLS symbol and it will try to access it but |
||||
as the program has been compiled without -lpthread the TLS base register |
||||
(%gs on i386) is not setup and it will result in: |
||||
Cannot access memory at address 0x8 |
||||
|
||||
Attached suggestion patch how to deal with the most common "errno" symbol |
||||
for the most common under-ggdb3 compiled programs. |
||||
|
||||
Original patch hooked into target_translate_tls_address. But its inferior |
||||
call invalidates `struct frame *' in the callers - RH BZ 690908. |

While thinking about it overriding some GDB _commands_ was not my intention. |
||||
|
||||
There is a general assumption if I have a shell COMMAND and some FILE I can do |
||||
$ COMMAND FILE |
||||
and COMMAND will appropriately load the FILE. |
||||
|
||||
FSF GDB currently needs to specify also the executable file for core files |
||||
which already inhibits this intuitive expectation. OTOH with the build-id |
||||
locating patch which could allow such intuitive start notneeding the |
||||
executable file. Still it currently did not work due to the required "-c": |
||||
$ COMMAND -c COREFILE |
||||
|
||||
Entering "file", "core-file" or "attach" commands is already explicit enough |
||||
so that it IMO should do what the command name says without any |
||||
autodetections. The second command line argument |
||||
(captured_main->pid_or_core_arg) is also autodetected (for PID or CORE) but |
||||
neither "attach" accepts a core file nor "core-file" accepts a PID. |
||||
|
||||
|
||||
The patch makes sense only with the build-id patchset so this is not submit |
||||
for FSF GDB inclusion yet. I am fine with your patch (+/- Hui Zhu's pending |
||||
bfd_check_format_matches) as the patch below is its natural extension. |
||||

Subject: [patch 3/3] attach-fail-reasons: SELinux deny_ptrace |
||||
|
||||
Hi, |
||||
|
||||
and here is the last bit for new SELinux 'deny_ptrace': |
||||
https://bugzilla.redhat.com/show_bug.cgi?id=786878 |
||||
|
||||
As even PTRACE_TRACEME fails in such case it needs to install hook for even |
||||
that event. |
||||
|
||||
|
||||
Thanks, |
||||
Jan |

Subject: [PATCH 2/2] PR 15231: import bare DW_TAG_lexical_block |
||||
|
||||
Local variables in lambdas are not accessible |
||||
https://sourceware.org/bugzilla/show_bug.cgi?id=15231 |

if (!dwarf2_get_pc_bounds (die, &lowpc, &highpc, cu, NULL)) |

Where DW_TAG_lexical_block has no attributes. Such whole subtree is currently |
||||
dropped by GDB while I think it should just import all its children DIEs. |
||||
|
||||
It even XFAIL->XPASSes gdb.ada/out_of_line_in_inlined.exp: |

commit 0fa7fe506c242b459c4c05d331e7c7d66fb52390 |

Author: Joel Brobecker <brobecker@adacore.com> |
||||

Subject: [PATCH 1/3] Never kill PID on: gdb exec PID |
||||
|
||||
Hi, |
||||
|
||||
in some cases with deleted main executable GDB will want to kill the inferior. |
||||
|
||||
$ cp /bin/sleep /tmp/sleep;/tmp/sleep 1h&p=$! |
||||
$ rm /tmp/sleep |
||||
$ gdb /tmp/sleep $p |
||||
GNU gdb (GDB) 7.10.50.20151016-cvs |
||||
/tmp/sleep: No such file or directory. |
||||
Attaching to process 9694 |
||||
/tmp/sleep (deleted): No such file or directory. |
||||
A program is being debugged already. Kill it? (y or n) _ |
||||
|
||||
The first attachment of "/tmp/sleep" commandline argument errors at: |
||||
|
||||
#0 throw_error (error=GENERIC_ERROR, fmt=0x116d135 "%s.") at ./common/common-exceptions.c:371 |
||||
#1 in throw_perror_with_name (errcode=GENERIC_ERROR, string=0x7fffffffdb96 "/dfsfds") at utils.c:974 |
||||
#2 in perror_with_name (string=0x7fffffffdb96 "/dfsfds") at utils.c:982 |
||||
#3 in exec_file_attach (filename=0x7fffffffdb96 "/dfsfds", from_tty=1) at exec.c:268 |
||||
267 if (scratch_chan < 0) |
||||
268 perror_with_name (filename); |
||||
#4 in catch_command_errors_const (command=0x80f59f <exec_file_attach>, arg=0x7fffffffdb96 "/dfsfds", from_tty=1) at main.c:395 |

||||
1051 if (catch_command_errors_const (exec_file_attach, execarg, |
||||
1052 !batch_flag)) |
||||
|
||||
Then GDB tries to attach to the process $p: |
||||
|
||||
#0 inferior_appeared (inf=0x240e0b0, pid=29210) at inferior.c:305 |
||||

||||
1082 if (catch_command_errors (attach_command, pid_or_core_arg, |
||||

||||
|
||||
This succeeds and since this moment GDB has a valid inferior. But despite that |
||||
the lines |
||||
1082 if (catch_command_errors (attach_command, pid_or_core_arg, |
||||

I find it a bug in DWARF and gdb behaves correctly according to it. From the |
||||
current DWARF's point of view the is a function call which you skip by "next". |
||||
|
||||
If you hide any /usr/lib/debug such as using: |
||||
gdb -nx -ex 'set debug-file-directory /qwe' -ex 'file ./tpcommon_gfortran44' |
||||
and use "step" command instead of "next" there it will work. |
||||
(You need to hide debuginfo from libgomp as you would step into libgomp sources |
||||
to maintain the threads for execution.) |
||||
|
||||
There should be some DWARF extension for it, currently tried to detect |
||||
substring ".omp_fn." as this function is called "MAIN__.omp_fn.0" and do not |
||||
consider such sub-function as a skippable by "next". |
||||
|
||||
Another problem is that with "set scheduler-locking" being "off" (default |
||||
upstream) or "step" (default in F/RHEL) the simultaneous execution of the |
||||
threads is inconvenient. Setting it to "on" will lockup the debugging as the |
||||
threads need to get synchronized at some point. This is a more general |
||||
debugging problem of GOMP outside of the scope of this Bug. |

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, |
||||

Subject: [PATCH] "enable count" user input error handling (PR gdb/15678) |
||||
|
||||
Typing "enable count" by itself crashes GDB. Also, if you omit the |
||||
breakpoint number/range, the error message is not very clear: |
||||
|
||||
(gdb) enable count 2 |
||||
warning: bad breakpoint number at or near '' |
||||
(gdb) enable count |
||||
Segmentation fault (core dumped) |
||||
|
||||
With this patch, the error messages are slightly more helpful: |
||||
|
||||
(gdb) enable count 2 |
||||
Argument required (one or more breakpoint numbers). |
||||
(gdb) enable count |
||||
Argument required (hit count). |
||||
|
||||
They are not as helpful to the user as I would like, but it's better |
||||
than crashing. Suggestions are welcome. |

||||
+When GDB finds a symbol file, it scans the symbols in the file in order |
||||
+to construct an internal symbol table. This lets most GDB operations |
||||
+work quickly--at the cost of a delay early on. For large programs, |
||||
+this delay can be quite lengthy, so GDB provides a way to build an |
||||
+index, which speeds up startup. |
||||
+ |
||||
+To determine whether a file contains such an index, use the command |
||||
+@command{readelf -S filename}: the index is stored in a section named |
||||
+@code{.gdb_index}. Note that the index is never generated for files that do |
||||
+not contain DWARF debug information (sections named @code{.debug_*}). |
