When running gdb.python/lib-types.exp, we have an xpass:
...
(gdb) python print (str (typedef_const_typedef_class1_ref_obj.type))^M
typedef_const_typedef_class1_ref^M
(gdb) XPASS: gdb.python/lib-types.exp: \
python print (str (typedef_const_typedef_class1_ref_obj.type)) \
(PRMS gcc/55641)
...
When running the same with gcc 4.8, we have an xfail instead:
...
(gdb) python print (str (typedef_const_typedef_class1_ref_obj.type))^M
const typedef_const_typedef_class1_ref^M
(gdb) XFAIL: gdb.python/lib-types.exp: \
python print (str (typedef_const_typedef_class1_ref_obj.type)) \

Fix the xpass by xfailing only for the gcc 4.8 pattern.

This commit extends the CLI a bit for multi-target, in three ways.
#1 - New "info connections" command.
This is a new command that lists the open connections (process_stratum
targets). For example, if you're debugging two remote connections, a
couple local/native processes, and a core dump, all at the same time,
you might see something like this:
(gdb) info connections
Num What Description
1 remote 192.168.0.1:9999 Remote serial target in gdb-specific protocol
2 remote 192.168.0.2:9998 Remote serial target in gdb-specific protocol
* 3 native Native process
4 core Local core dump file
#2 - New "info inferiors" "Connection" column
You'll also see a new matching "Connection" column in "info
inferiors", showing you which connection an inferior is bound to:
(gdb) info inferiors
Num Description Connection Executable
1 process 18526 1 (remote 192.168.0.1:9999) target:/tmp/a.out
2 process 18531 2 (remote 192.168.0.2:9998) target:/tmp/a.out
3 process 19115 3 (native) /tmp/prog1
4 process 6286 4 (core) myprogram
* 5 process 19122 3 (native) /bin/hello
#3 - Makes "add-inferior" show the inferior's target connection
"add-inferior" now shows you the connection you've just bound the
inferior to, which is the current process_stratum target:
(gdb) add-inferior
[New inferior 2]
Added inferior 2 on connection 1 (extended-remote localhost:2346)

The option framework documentation was speaking about a 'print -raw'
option, but this option does not exist.
This patch implements -raw-values option that tells to ignore the
active pretty printers when printing a value.
As we already have -raw-frame-arguments, I thought -raw-values
was more clear, in particular to differentiate
set print raw-values and set print raw-frame-arguments.

The documentation for make-breakpoint from the Guile API and the `spec'
variant of the gdb.Breakpoint constructor from the Python API state that
the format acceptable for location strings is the same as that accepted
by the break command. However, using the -probe qualifier at the
beginning of the location string causes a GDB internal error as it
attempts to decode a probe location in the wrong code path. Without this
functionality, there doesn't appear to be another way to set breakpoints
on probe points from Python or Guile scripts.
This patch introduces a new helper function that returns a
breakpoint_ops instance appropriate for a parsed location and updates
the Guile and Python bindings to use said function, rather than the
current hard-coded use of bkpt_breakpoint_ops. Since this logic is
duplicated in the handling of the `break' and `trace' commands, those
are also updated to call into the new helper function.

If gdb.lookup_static_symbol is going to return a single symbol then it
makes sense (I think) for it to return a context sensitive choice of
symbol, that is the global static symbol that would be visible to the
program at that point.
However, if the user of the python API wants to instead get a
consistent set of global static symbols, no matter where they stop,
then they have to instead consider all global static symbols with a
given name - there could be many. That is what this new API function
offers, it returns a list (possibly empty) of all global static
symbols matching a given name (and optionally a given symbol domain).

When using gdb.lookup_static_symbol I think that GDB should find
static symbols (global symbol with static linkage) from the current
object file ahead of static symbols from other object files.
This means that if we have two source files f1.c and f2.c, and both
files contains 'static int foo;', then when we are stopped in f1.c a
call to 'gdb.lookup_static_symbol ("foo")' will find f1.c::foo, and if
we are stopped in f2.c we would find 'f2.c::foo'.
Given that gdb.lookup_static_symbol always returns a single symbol,
but there can be multiple static symbols with the same name GDB is
always making a choice about which symbols to return. I think that it
makes sense for the choice GDB makes in this case to match what a user
would get on the command line if they asked to 'print foo'.

* gdb.python/py-symbol.c: Declare and call function from new

The documentation for Progspace.block_for_pc says:
Return the innermost gdb.Block containing the given pc value. If the
block cannot be found for the pc value specified, the function will
return None.
However, the implementation actually throws an error for invalid
addresses, like this:
(gdb) python print gdb.current_progspace ().block_for_pc (1)
Traceback (most recent call last):
File "<string>", line 1, in <module>
RuntimeError: Cannot locate object file for block.
Error while executing Python code.
(gdb)
This has been the behaviour since the command was first added (when
the documentation was still as above) in this commit:
commit f3e9a8177c
Date: Wed Feb 24 21:18:28 2010 +0000
Since that commit the code in question has moved around, but the
important parts are largely unchanged. The function in question is
now in py-progspace.c:pspy_block_for_pc.
Examining the code shows that the real state is more complex than just
the function throws an error instead of returning None, instead the
real situation is:
1. If we can't find a compilation unit for the $pc value then we
throw an error, but
2. If we can find a compilation unit, but can't find a block within
the compilation unit for the $pc then return None.
I suspect for most users of the Python API this distinction is
irrelevant, and I propose that we standardise on one single failure
mechanism.
Given the function can currently return None in some cases, and is
documented to return None on error, I propose we make that the case
for all error paths, which is what this patch does.
As the Progspace.block_for_pc method is currently untested, I've added
some basic tests including for a call with an invalid $pc.
This is potentially an API breaking change, though an undocumented
part of the API. Also, users should have been checking and handling a
None return value anyway, so my hope is that this shouldn't be too
disruptive.

* python/py-progspace.c (pspy_block_for_pc): Return None for all
error paths.

This commit removes some, but not all, of the test name duplication
within the gdb.python tests. On my local machine this takes the
number of duplicate test names in this set of tests from 174 to 85.
It is possible that different setups might encounter more duplicate
tests.

* gdb.python/py-value.exp: Likewise.
GDB's py-format-string test case depends on endianness. In particular it
relies on the first byte of the machine representation of 42 (as an int)
to be 42 as well. While this is indeed the case for little-endian
machines, big-endian machines store a zero in the first byte instead. The
wrong assumption leads to lots of FAILs on such architectures.
Fix this by filling the affected union with bytes of the same value, such
that endianness does not matter. Use the value 42, to keep the character
in the first byte unchanged.
gdb/testsuite/ChangeLog:
* gdb.python/py-format-string.c (string.h): New include.
(main): Fill a_struct_with_union.the_union.an_int with bytes of
the same value, for endianness-independence.
* gdb.python/py-format-string.exp (default_regexp_dict)
(test_pretty_structs, test_format): Adjust expected output to the
changed initialization.
The way unrecognized escape sequences are handled has changed in
Python 3.8: users now see a SyntaxWarning message, which will
eventually become a SyntaxError in future versions of Python:
(gdb) source /blabla/gdb.python/py-xmethods/py-xmethods.py
/blabla/gdb.python/py-xmethods/py-xmethods.py:204: SyntaxWarning: invalid escape seque
nce \+
'operator\+',
/blabla/gdb.python/py-xmethods/py-xmethods.py:211: SyntaxWarning: invalid escape seque
nce \+
'operator\+\+',
One of our testcases, gdb.python/py-xmethods.exp, contains strings in
the form of "operator\+". This is not recognized by Python, but is
still needed by the testsuite to work properly. The solution is
simple: we just have to make sure these strings are marked as
raw (i.e, r""). This is what this patch does. I took the opportunity
to also convert other strings to raw, which, in two cases, allowed the
removal of an extra backslash.
I tested this using Python 3.7 and Python 3.8, and everything works
fine.
I think I could push this as obvious, but decided to send it to
gdb-patches just in case.

The problem is that gdb_test_multiple here:

}
...
specifies a regexp that ends with ".*" but doesn't specify the expected
$gdb_prompt.
Consequently, due to check-read1, the ".*" is matched to "" and the remaining
$gdb_prompt is read by the the following gdb_py_test_silent_cmd, which has
its own $gdb_prompt read by the following gdb_py_test_silent_cmd, which has
its own $gdb_prompt causing a mismatch for the following gdb_test_multiple:

gdb_test_multiple "python gdb.prompt_hook = error_prompt" "set the hook" {
-re "Traceback.*File.*line.*RuntimeError.*Python exception called.*" {

which causes both FAILs.
The second gdb_test_multiple has the same problem as the first, but it happens
not to cause a FAIL because it's followed by a gdb_py_test_silent_cmd and a
clean_restart.

Currently, with:
(gdb) catch catch
Catchpoint 1 (catch)
(gdb) catch throw
Catchpoint 2 (throw)
(gdb) catch rethrow
Catchpoint 3 (rethrow)
You get:
(gdb) info breakpoints
Num Type Disp Enb Address What
1 breakpoint keep y 0x0000000000b122af exception catch
2 breakpoint keep y 0x0000000000b1288d exception throw
3 breakpoint keep y 0x0000000000b12931 exception rethrow
I think it doesn't make much sense usability-wise, to show a
catchpoint as a breakpoint. The fact that GDB sets a breakpoint at
some magic address in the C++ run time is an implementation detail,
IMO. And as seen in the previous patch, such a catchpoint can end up
with more than one location/address even, so showing a single address
isn't entirely accurate.
This commit hides the addresses from view, and makes GDB show
"catchpoint" for type as well:
(gdb) info breakpoints
Num Type Disp Enb Address What
1 catchpoint keep y exception catch
2 catchpoint keep y exception throw
3 catchpoint keep y exception rethrow
This comment in the code seems telling:
/* We need to reset 'type' in order for code in breakpoint.c to do
the right thing. */
cp->type = bp_breakpoint;
It kind of suggests that the reason catchpoints end up shown as
breakpoints was that it was easier to implement them that way, rather
than a desired property.
This commit fixes things up to make it possible to have bp_catch
breakpoints have software/hardware breakpoint locations, thus
eliminating the need for that hack:
- redo breakpoint_address_is_meaningful in terms of the location's
type rather than breakpoint type.
- teach bpstat_what about stepping over the catchpoint locations.
- install a allocate_location method for "catch catch/throw/rethrow",
one that forces the location type.
Note that this also reverts the gdb hunk from:

A following patch will introduce options for the "backtrace" command,
based on some "set print" and "set backtrace" settings. There's one
setting in particular that is a bit annoying if we want to describe
the backtrace options and the settings commands using the same data
structures:
"set print raw frame-arguments"
The problem is that space between "raw" and "frame-arguments".
Calling the option
"bt -raw frame-arguments"
would be odd. So I'm calling the option
"bt -raw-frame-arguments"
instead.
And for consistency, this patch renames the set/show commands to:
"set print raw-frame-arguments"
"show print raw-frame-arguments"
I.e., dash instead of space. The old commands are left in place, but
marked deprecated.
We need to adjust a couple testcases, because the relevant tests use
gdb_test_no_output and the old commands are no longer silent:
(gdb) set print raw frame-arguments on
Warning: command 'set print raw frame-arguments' is deprecated.
Use 'set print raw-frame-arguments'.

A user here noticed that the Python Value.string method did not work
for Ada arrays. I tracked this down to an oddity in value_as_address
-- namely, it calls coerce_array, but that function will not force
array coercion when the language has c_style_arrays=false, as Ada
does.
This patch fixes the problem by changing c_get_string so that arrays
take the "in GDB's memory" branch. The actual patch is somewhat more
complicated than you might think, because the caller can request more
array elements than the type allows. This is normal when the type is
using the C struct hack.
Tested on x86-64 Fedora 29.

Introduce a new print setting max-depth which can be set with 'set
print max-depth DEPTH'. The default value of DEPTH is 20, but this
can also be set to unlimited.
When GDB is printing a value containing nested structures GDB will
stop descending at depth DEPTH. Here is a small example:
typedef struct s1 { int a; } s1;
typedef struct s2 { s1 b; } s2;
typedef struct s3 { s2 c; } s3;
typedef struct s4 { s3 d; } s4;
s4 var = { { { { 3 } } } };
The following table shows how various depth settings affect printing
of 'var':
| Depth Setting | Result of 'p var' |
|---------------+--------------------------------|
| Unlimited | $1 = {d = {c = {b = {a = 3}}}} |
| 4 | $1 = {d = {c = {b = {a = 3}}}} |
| 3 | $1 = {d = {c = {b = {...}}}} |
| 2 | $1 = {d = {c = {...}}} |
| 1 | $1 = {d = {...}} |
| 0 | $1 = {...} |
Only structures, unions, and arrays are replaced in this way, scalars
and strings are not replaced.
The replacement is counted from the level at which you print, not from
the top level of the structure. So, consider the above example and
this GDB session:
(gdb) set print max-depth 2
(gdb) p var
$1 = {d = {c = {...}}}
(gdb) p var.d
$2 = {c = {b = {...}}}
(gdb) p var.d.c
$3 = {b = {a = 3}}
Setting the max-depth to 2 doesn't prevent the user from exploring
deeper into 'var' by asking for specific sub-fields to be printed.
The motivation behind this feature is to try and give the user more
control over how much is printed when examining large, complex data
structures.
The default max-depth of 20 means that there is a change in GDB's
default behaviour. Someone printing a data structure with 20 levels
of nesting will now see '{...}' instead of their data, they would need
to adjust the max depth, or call print again naming a specific field
in order to dig deeper into their data structure. If this is
considered a problem then we could increase the default, or even make
the default unlimited.
This commit relies on the previous commit, which added a new field to
the language structure, this new field was a string that contained the
pattern that should be used when a structure/union/array is replaced
in the output, this allows languages to use a syntax that is more
appropriate, mostly this will be selecting the correct types of
bracket '(...)' or '{...}', both of which are currently in use.
This commit should have no impact on MI output, expressions are
printed through the MI using -var-create and then -var-list-children.
As each use of -var-list-children only ever displays a single level of
an expression then the max-depth setting will have no impact.
This commit also adds the max-depth mechanism to the scripting
language pretty printers following basically the same rules as for the
built in value printing.
One quirk is that when printing a value using the display hint 'map',
if the keys of the map are structs then GDB will hide the keys one
depth level after it hides the values, this ensures that GDB produces
output like this:
$1 = map_object = {[{key1}] = {...}, [{key2}] = {...}}
Instead of this less helpful output:
$1 = map_object = {[{...}] = {...}, [{...}] = {...}}
This is covered by the new tests in gdb.python/py-nested-maps.exp.

This renaming was done to stay consistent with the naming of the new

If an convenience function is defined in python (or guile), then
currently this will not work in Fortran, instead the user is given
this message:
(gdb) set language fortran
(gdb) p $myfunc (3)
Cannot perform substring on this type
Compare this to C:
(gdb) set language c
(gdb) p $myfunc (3)
$1 = 1
After this patch we see the same behaviour in both C and Fortran.
I've extended the test to check that all languages can call the
convenience functions - only Fortran was broken.
When calling convenience functions in Fortran we don't need to perform
the same value preparation (passing by pointer) that we would for
calling a native function - passing the real value is fine.

but it doesn't allow to specify additional formatting settings, for

allows specifying more formatting options, thus giving access to more
features provided by the internal C function common_val_print ().

The documentation say that the display_hint method must return a
string to serve as a display hint, and then goes on to list some
acceptable strings.
However, if we don't supply the display_hint method then we get a
default display style behaviour and there's currently no way (in the
python api) to force this default behaviour.
The guile api allows #f to be used in order to force the default
display style behaviour, and this is documented.
Currently, using None in the python api also forces the default
display behaviour.
This commit extends the documentation to make returning None from the
display_hint method an official mechanism by which the user can get
the default display style.
I've extended one of the existing tests to cover this case.

This makes the test names unique in gdb.python/py-prettyprint.exp, it
also switches to use gdb_breakpoint and gdb_continue_to_breakpoint
more so that we avoid test names with the source line number in - this
is bad if the test source ever changes as the test names will then
change.
One final change is to switch from using gdb_py_test_silent_cmd to use
gdb_test_no_output, the former should be used for running python
commands and can catch any thrown exception. However, in this case
the command being run is not a python command, its just a normal GDB
CLI command that produces no output, so lets use the appropriate
wrapper function.

A while back I typed "info pretty-printers" with a large number of

that gdb printed a Python exception in this case.
It seems to me that, instead, quitting pagination (or control-c'ing a

normally handles a quit.

Since commit
56bcdbea2b ("Let gdb.execute handle multi-line commands")
command repetition after using the `gdb.execute` Python function
fails (the previous command is not repeated anymore). This happens
because read_command_lines_1 sets dont_repeat, but the call to
prevent_dont_repeat in execute_gdb_command is later.
The fix is to move the call to prevent_dont_repeat to the beginning of
the function.
Tested on my laptop (ArchLinux-x86_64).

The test loop in test_python_inline_or_multiline was not checking for the

Spotted this error because sometimes the gdb prompt does get processed
correctly and the final tests are run, causing it to show up in the
racy tests script output.
Fix by ensuring the prompt is always checked for. To do this the list
style needs reformatting so that variables get expanded.

I've written a couple of gdb unwinders in Python, and while doing so,
I wanted to find the architecture of the inferior. (In an unwinder in
particular, one can't use the frame's architecture, because there is

I would have chosen an attribute and not a method here, but seeing
that Frame.architecture is a method, I chose a method as well, for

This patch is another attempt to fix PR cli/19551. Unlike my previous
attempt, it doesn't print progress. Instead, it just changes some
messages and adds newlines to make the output a bit nicer.
It also removes the "done." text that was previously emitted. The
idea here is that it is obvious when gdb is done reading debug info,
as it starts then doing something else; and that while this message
did not provide much benefit to users, it did make it harder to make
the output clean.

A convention in the Python layer is that raising a gdb.GdbError will
not print the Python stack -- instead the exception is treated as any
other gdb exception.
PR python/18852 asks that this treatment be extended the the
get_set_value method of gdb.Parameter. This makes sense, because it
lets Python-created parameters act like gdb parameters.

typy_template_argument did not check if the template argument was
non-negative. A negative value could cause a gdb crash.
