Sergio Durigan Junior d92f7ee31f This is a simple bug. target_disable_btrace and target_teardown_btrace,
both from gdb/target.c, do a "return" calling another function.  But both
are marked as void.  Despite the fact that the functions being called are
void as well, this is wrong.  This patch fixes this by calling the functions
and then returning in the next line.

Pedro Alves 578d3588ee Stop using errno values around target_xfer interfaces and memory errors.
target_read_memory & friends build on top of target_read (thus on top
of the target_xfer machinery), but turn all errors to EIO, an errno
value.  I think we'd better convert all these to return a
target_xfer_error too, like target_xfer_partial in a previous patch.
The patch starts by doing that.

(The patch does not add a enum target_xfer_error value for '0'/no
error, and likewise does not change the return type of several of
these functions to enum target_xfer_error, because different functions
return '0' with different semantics.)

I audited the tree for memory_error calls, EIO checks, places where
GDB hardcodes 'errno = EIO', and also for strerror calls.  What I
found is that nowadays there's really no need to handle random errno
values, other than the EIOs gdb itself hardcodes.  No doubt errno
values would appear in common code back in the day when
target_xfer_memory was the main interface to access memory, but
nowadays, any errno value that deprecated interface could return is
just absorved by default_xfer_partial:

      else if (xfered == 0 && errno == 0)
	/* "deprecated_xfer_memory" uses 0, cross checked against
           ERRNO as one indication of an error.  */
	return 0;
      else
	return -1;

There are two places in the code that check for EIO and print "out of
bounds", and defer to strerror for other errors.  That's
c-lang.c:c_get_string, and valprint.c.:val_print_string.  AFAICT, the
strerror branch can never be reached nowadays, as the only error
possible to get at those points is EIO, given that it's GDB itself
that set that errno value (in target_read_memory, etc.).

breakpoint.c:insert_bp_location always prints the error val as if an
errno, returned by target_insert_breakpoint, with strerr.  Now the
error here is either always EIO for mem-break.c targets (again
hardcoded by the target_read_memory/target_write_memory functions), so
this always prints "Input/output error" or similar (depending on
host), or, for remote targets (and probably others), this gem:

  Error accessing memory address 0x80200400: Unknown error -1.

This patch makes these 3 places print the exact same error
memory_error prints.  This changes output, but I think this is better,
for making memory error output consistent with other commands, and, it
means we have a central place to tweak for memory errors.

E.g., this changes:

 Cannot insert breakpoint 1.
 Error accessing memory address 0x5fc660: Input/output error.

to:

 Cannot insert breakpoint 1.
 Cannot access memory at address 0x5fc660

Which I find pretty much acceptable.

Surprisingly, only py-prettyprint.exp had a regression, for needing an
adjustment.  I also grepped the testsuite for the old errors, and
found no other hits.

Now that errno values aren't used anywhere in any of these memory
access related routines, I made memory_error itself take a
target_xfer_error instead of an errno.  The new
target_xfer_memory_error function added recently is no longer
necessary, and is thus removed.

Tested on x86_64 Fedora 17, native and gdbserver.

dwarf2_evaluate_loc_desc_full (frame #7) knows to handle
NOT_AVAILABLE_ERROR errors, but read_memory always throws
a generic error.

Presently, only the value machinery knows to handle unavailable
memory.  We need to push the awareness down to the target_xfer layer,
making it return a finer grained error indication.  We can only return
a generic -1 nowadays, which leaves the upper layers with no clue on
why the xfer failed.  Use target_xfer_partial directly, rather than
propagating the error through target_read_memory so as to get a better
address to display in the error message.

(target_read_memory & friends build on top of target_read (thus the
target_xfer machinery), but turn all errors to EIO, an errno value.  I
think this is a mistake, and we'd better convert all these to return a
target_xfer_error too, but that can be done separately.  I looked
around a bit over memory_error calls, and the need to handle random
errno values, other than the EIOs gdb itself hardcodes, probably comes
(only) from deprecated_xfer_memory, which uses errno for error
indication, but I didn't look exhaustively.  We should really get rid
of deprecated_xfer_memory and of passing down errno values as error
indication in target_read & friends methods).

Tested on x86_64 Fedora 17, native and gdbserver.  Fixes the test in
the PR, which will be added to the testsuite later.

Tom Tromey 7fdc15218d remove pop_target
This patch fixes the target double-close problem (PR remote/15266),
and in the process removes pop_target entire (PR remote/15256).

The first issue is that pop_target calls target_close.  However, it
then calls unpush_target, which also calls target_close.  This means
targets must be able to be closed twice.  Not only is this strange,
but it also directly contradicts the contract of to_xclose targets.
(We currently have just a single such target, and it is never pushed;
but I plan to add more, and so this latent bug is triggered.)

The second issue is that it seems to me that calling pop_target is
often unsafe.  This is what cropped up in 15256, where the remote
target assumed that it could pop_target -- but there was another
target higher on the stack, leading to confusion.

But, it is always just as easy to call unpush_target as it is to call
pop_target; and it is also safer.  So, removing pop_target seemed like
an improvement.

Finally, this adds an assertion to target_close to ensure that no
currently-pushed target can be closed.

Built and regtested on x86-64 Fedora 18; both natively and using the
native-gdbserver board file.

Tom Tromey c22a2b88fe don't call add_target for thread_db_ops
Right now, "help target" will include this line:

    target multi-thread -- Threads and pthreads support

However, it doesn't make sense to invoke "target multi-thread".

This patch fixes the problem by not registering the multi-thread
target.  add_target does some needed initialization of the target_ops,
so I broke this out into a new function.

It isn't clear to me whether this patch requires a test case or not.
I'm not sure whether there are other unregistered targets; but if
there are, it seems unlikely that we test for their absence from the
help.

Pedro Alves 39086a0e13 Avoid invalid pointer to pointer conversions.
Casts between 'char **' <-> 'unsigned char **' and 'char **' <-> const
char **' are actually invalid:

  http://gcc.gnu.org/ml/gcc-help/2013-03/msg00118.html

In a nutshell, char (and variants) can alias anything, but pointers to
chars get no special treatment (cf. C99/N1256, 6.5/7).

Turns out older gcc's actually warn/complain on these constructs,
though newer one's don't:

  http://sourceware.org/ml/gdb-patches/2013-03/msg00429.html
  http://sourceware.org/ml/gdb-patches/2013-03/msg00430.html

This patch fixes the cases I added last week.  It also fixes one other
preexisting case in charset.c, though it seems even older gccs don't
complain of char * <-> const char * aliasing.

Tested on x86_64 Fedora 17.

gdb/
2013-03-11  Pedro Alves  <palves@redhat.com>

	* charset.c (convert_between_encodings): Don't cast between
	different pointer to pointer types.  Instead, make the 'inp' local
	be of the type iconv expects.
	(wchar_iterate): Don't cast between different pointer to pointer
	types.  Instead, use new pointer local of the type iconv expects.
	* target.c (target_read_stralloc, target_fileio_read_stralloc):
	Add new local of type char pointer, and use it to get a
	char/string view of the byte buffer, instead of casting between
	pointer to pointer types.

../../src/gdb/target.c: In function ‘target_read_stralloc’:

...

This is about the same as the previous patch.

Functions that take or return ascii-ish string arguments usually use
char* for parameters/return.  That means that at points we call into
target methods that work with binary blobs, we need casts to/from
gdb_byte*/char*.  To choose which type for the variables, I usually go
based on which requires the fewer casts, and what the contents of the
variable are supposed to hold, which often gives the same answer.

Pedro Alves e362b51003 Use gdb_byte for bytes from the program being debugged.
gdb_byte should be used for bytes from the program being debugged.  We
have many places using char or unsigned char instead all over the
existing ports, and more ends up added over time due to copy/paste as
new code is based on old code.
