Pedro Alves 7f7cc26500 Fix PR gdb/15294: list with unlimited listsize broken
Currently, "set listsize -1" is supposed to mean "unlimited" source
lines, but, alas, it doesn't actually work:

 (gdb) set listsize -1
 (gdb) show listsize
 Number of source lines gdb will list by default is unlimited.
 (gdb) list 1
 (gdb) list 1
 (gdb) list 1
 (gdb) set listsize 10
 (gdb) list 1

Before this patch:

     http://sourceware.org/ml/gdb-patches/2012-08/msg00367.html

was applied, the "set listsize" command was a var_integer command, and
"unlimited" was set with 0.  Internally, var_integer maps 0 to INT_MAX

   case var_integer:
      {
      ...
	if (val == 0 && c->var_type == var_integer)
	  val = INT_MAX;

The change in that patch to zuinteger_unlimited command, meant that -1
is left as -1 in the command's control variable (lines_to_list), and
the code in source.c isn't expecting that -- it only expects positive
numbers.

I previously suggested fixing the code and keeping the new behavior,
but I found that "set listsize 0" is currently used in the wild, and
we do have a bunch of other commands where "0" means unlimited, so I'm
thinking that changing this command alone in isolation is not a good
idea.

So I now strongly prefer reverting back the behavior in 7.6 to the
same behavior the command has had since 2006 (0==unlimited, -1=error).
Before that, set listsize -1 would be accepted as unlimited as well.

After 7.6 is out, in mainline, we can get back to reconsidering
changing this command's behavior, if there's a real need for being
able to suppress output.  For now, let's play it safe.

The "list line 1 with unlimited listsize" test in list.exp was
originally written years and years ago expecting 0 to mean "no
output", but GDB never actually worked that way, even when the tests
were written, so the tests had been xfailed then.  This patch now
adjusts the test to the new behavior, so that the test actually
passes, and the xfail is removed.

Pedro Alves 840a9a1f86 Forbid "set history size (INT_MAX..UINT_MAX)"
The whole readline interface is signed, and works with the 0..INT_MAX
range.

We don't allow setting the size to UINT_MAX directly.  The documented
user visible interface is "use 0 for unlimited".  The UINT_MAX
representation is an implementation detail we could change, e.g., by
keeping a separate flag for "unlimited", which is actually what the
readline interface does (stifled vs non stifled).  Generically
speaking, exposing this detail to clients of the interface may make
our lives complicated when we find the need to extend the range of
some command in the future, and it's better if users
(frontends/scripts) aren't relying on anything but what we tell them
to use for "unlimited".  Making values other than 0 error out is the
way to prevent users from using those ranges inappropriately.  Quite
related, note:

    (gdb) set history size 0xffffffff
    integer 4294967295 out of range

  But,

    (gdb) set history size 0xfffffffe
    (gdb) show history size
    The size of the command history is unlimited.

    (gdb) set history size 0x100000000
    integer 4294967296 out of range

If values over INT_MAX are accepted as unlimited, then there's no good
argument for only accepting [INT_MAX..UINT_MAX) as valid "unlimited"
magic numbers, while not accepting [UINT_MAX..inf).

Making the setting's control variable of different type (unsigned int)
of the rest of the related code (int) adds the need to recall that one
variable among all these is unsigned, and that one need to think about
whether these comparisons are signed or unsigned, along with the
promotion/conversion rules.  Since this is an easy to forget detail,
this patch renames the variable to at least make it more obvious that
this variable is not one of GNU history's public int variables, which
are all signed.  We don't actually need the only code that presently
is affected by this, though, the code that is computing the current
history's length.  We can just use GNU history's history_length
instead:

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Variable: int history_length
    The number of entries currently stored in the history list.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

/* Return the history entry which is logically at OFFSET in the history array.
   OFFSET is relative to history_base. */
HIST_ENTRY *
history_get (offset)
     int offset;
{
  int local_index;

  local_index = offset - history_base;
  return (local_index >= history_length || local_index < 0 || the_history == 0)
		? (HIST_ENTRY *)NULL
		: the_history[local_index];
}
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

At the time this code was added (gdb 4.13 ~1994), 'history_length' was
extern, but not documented in readline's GNU history documents, so I
guess it wasn't considered public then and the loop was the
workaround.

One of the warts of GDB choosing 0 to mean unlimited is that "set
history size 0" behaves differently from 'HISTSIZE=0 gdb'.  The latter
leaves GDB with no history, while the former means "unlimited"...

 $ HISTSIZE=0 ./gdb
 ...
 (gdb) show history size
 The size of the command history is 0.

We shouldn't really change what HISTSIZE=0 means, as bash, etc. also
handle 0 as real zero, and zero it's what really makes sense.

Pedro Alves 2c619be216 ser-tcp.c: Small signed->unsigned cleanup.
The "set tcp connect-timeout" variable is unsigned:

  /* Timeout period for connections, in seconds.  */

  static unsigned int tcp_retry_limit = 15;

  if (*polls > tcp_retry_limit * POLL_INTERVAL)
    {
      errno = ETIMEDOUT;

Pedro Alves 1b49319248 Make "set/show remoteaddresssize" a zuinteger command instead of uinteger.
It makes no sense to talk about an "unlimited" address size in this
context.

 (gdb) show remoteaddresssize
 The maximum size of the address (in bits) in a memory packet is 0.
 (gdb) set remoteaddresssize 0
 (gdb) show remoteaddresssize
 The maximum size of the address (in bits) in a memory packet is unlimited.

"set remoteaddresssize 0" mapping to UINT_MAX means you can't
force gdb through this path twice in the same GDB run:

  static CORE_ADDR
  remote_address_masked (CORE_ADDR addr)
  {
    unsigned int address_size = remote_address_size;

    /* If "remoteaddresssize" was not set, default to target address size.  */

Pedro Alves 7ee70bf518 record-full.c: Remove always true checks.
The "set record full insn-number-max" command is an uinteger command.
If the variable that holds the maximum count of logged instructions is
unsigned, it's better if the variable that holds the current number of
logged instructions is also unsigned.  Looking over the code, there's
no case the variable could end up negative.

Then, tests like "if (record_full_insn_max_num)" are always true,
because being a uinteger command means that "set record full
insn-number-max 0" is actually mapped to UINT_MAX internally.  IOW,
the command's variable is never 0.  The checks might make some sense
if 0 wasn't mapped to UINT_MAX, and 0 meant unlimited, but, that's not
how things work.

Pedro Alves dfd1f9bbf2 Make "set/show dcache line-size" and "set/show dcache size" zinteger commands instead of uinteger.
It doesn't make sense to request an "unlimited" dcache.  You want to
configure the cache with specific lines and length of lines.

It doesn't actually work anyway:

  (gdb) set dcache line-size 0
  Invalid dcache line size: 4294967295 (must be power of 2).

  (gdb) set dcache size 0
  (gdb) show dcache size
  Number of dcache lines is unlimited.

  (gdb) info dcache
  Dcache 4294967295 lines of 64 bytes each.
  No data cache available.

The code already has guards in place to forbid 0s:

static void
set_dcache_size (char *args, int from_tty,
		 struct cmd_list_element *c)
{
  if (dcache_size == 0)
    {
      dcache_size = DCACHE_DEFAULT_SIZE;
      error (_("Dcache size must be greater than 0."));
    }
  if (last_cache)
    dcache_invalidate (last_cache);
}

static void
set_dcache_line_size (char *args, int from_tty,
		      struct cmd_list_element *c)
{
  if (dcache_line_size < 2
      || (dcache_line_size & (dcache_line_size - 1)) != 0)
    {
      unsigned d = dcache_line_size;
      dcache_line_size = DCACHE_DEFAULT_LINE_SIZE;
      error (_("Invalid dcache line size: %u (must be power of 2)."), d);
    }
  if (last_cache)
    dcache_invalidate (last_cache);
}

So we now get:

  (gdb) set dcache line-size 0
  Invalid dcache line size: 0 (must be power of 2).
  (gdb) set dcache size 0
  Dcache size must be greater than 0.

Oleg Nesterov told me that the Linux kernel copies the parent's ptrace
options to fork/clone children, so there's no need for GDB to do that
manually.

I was actually a bit surprised, since I thought the ptracer had to
always set the ptrace options itself, and GDB is indeed calling
PTRACE_SETOPTIONS for each new fork child, if it'll stay attached.

Looking at the history of that code, I found that is was actually I
who added that set-ptrace-options-in-children bit, back in
http://sourceware.org/ml/gdb-patches/2009-05/msg00656.html.  But,
honestly, I don't recall why I needed that.  I think I may have just
blindly believed it was necessary.

I then looked back at the history of all the PTRACE_SETOPTIONS code we
have, and found that gdb never did copy the ptrace options before my
patch.  But, when gdbserver learnt to use PTRACE_EVENT_CLONE, at
http://sourceware.org/ml/gdb-patches/2007-10/msg00547.html, it was
made to do 'ptrace (PTRACE_SETOPTIONS, new_pid, 0,
PTRACE_O_TRACECLONE)' for all new clones.  Hmmm.  But, GDB itself
never did that, so it can't really ever have been necessary, I
believe, otherwise GDB should have been doing it too.

(GDBserver doesn't support following forks, and so naturally doesn't
do any PTRACE_SETOPTIONS on fork children.)

So this patch removes the -I believe- unnecessary ptrace syscalls.

Tested on x86_64 Fedora 17, native/gdbserver, and on x86_64 RHEL5
native/gdbserver (Linux 2.6.18, I think a ptrace-on-utrace kernel).
No regressions.

Casting to gdb_byte would fix it, however, writing an
unsigned int array like this

      static unsigned int hppa64_tramp[] = {
        0xeac0f000, /* bve,l (r22),%r2 */
        0x0fdf12d1, /* std r31,-8(,sp) */
        0x0fd110c2, /* ldd -8(,sp),rp */
        0xe840d002, /* bve,n (rp) */
        0x08000240  /* nop */
        ...

directly to target memory assumes the host endianness is the same as
the target's.  hppa is big endian, so I believe this patch should be
correct -- it defines the array as a gdb_byte array.  It uses a macro
to make the insn bytes a little more readable.  I thought of using
write_memory_unsigned_integer once for each element of the unsigned
int array, but this way keeps issuing a single target memory write /
roundtrip for the whole trampoline.

Pedro Alves ef0026f03b Fix PR gdb/15289 - "set remote hardware-watchpoint-limit" broken (zinteger commands)
This is a regression from 7.5, introduced/exposed by:
  http://sourceware.org/ml/gdb-patches/2012-07/msg00259.html

There are a series of issues with this code.

It does:

	unsigned int val = parse_and_eval_long (arg);
	^^^^^^^^^^^^

(unsigned, usually 32-bit) while parse_and_eval_long returns a LONGEST
(usually 64-bit), so we lose precision without noticing:

  (gdb) set remote hardware-watchpoint-limit 0x100000000
  (gdb) show remote hardware-watchpoint-limit 0x100000000
  The maximum number of target hardware watchpoints is 0.

While at it, print the invalid number with plongest, so the user sees
what GDB thought the number was:

  (gdb) set remote hardware-watchpoint-limit 0x100000000
  integer 4294967296 out of range

So with "set remote hardware-watchpoint-limit -1", val ends converted
to 0xffffffff, which then fails the

	else if (val >= INT_MAX)
	  error (_("integer %u out of range"), val);

test.

Looking at that INT_MAX check, we forbid INT_MAX itself, but we
shouldn't, as that does fit in 'int' -- we want to forbid values
_greater_ than INT_MAX (and less than INT_MIN, while at it):

  (gdb) set remote hardware-watchpoint-limit 2147483647
  integer 2147483647 out of range

The same problem is in the new var_zuinteger_unlimited code, which
also uses "int" for variable.

Also, when printing a 'signed int', we should use %d, not %u.

This adds a couple regression tests.  Not completely thorough in checking
all kinds of invalid input; I'm saving more exaustive testing around
zXXinteger commands for something like new test-assisting commands
like "maint test cmd-zinteger -1", where testing would focus on the
command types, and thus be independent of particular user commands of
particular GDB features.

Tested on x86_64 Fedora 17.
