"SyntaxWarning: invalid escape sequence")
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.

* gdb.python/py-xmethods.exp: Use raw strings when passing

This patch fixes several test ERRORs and FAILs seen from running
gdb.python tests on a remote Windows host. The problems fixed
generally fall into these categories:
- Failure to copy the .py script to the host.
- Confusion between build and host pathnames.
- Assuming pathnames printed on the host include "/" as a directory
separator.
- Tests that need to be conditionally disabled due to missing features
on the host, etc.

when running python/python.exp with check-read1, we get:
...
(gdb) PASS: gdb.python/python.exp: prompt substitution readline - end
python gdb.prompt_hook = error_prompt^M
Python Exception <type 'exceptions.RuntimeError'> Python exception calledPASS: gdb.python/python.exp: set hook

(gdb) PASS: gdb.python/python.exp: set the hook to default
python gdb.prompt_hook = None^M
(gdb) PASS: gdb.python/python.exp: set print-stack full for prompt error test

(gdb) FAIL: gdb.python/python.exp: set the hook
python gdb.prompt_hook = error_prompt^M
Traceback (most recent call last):^M
File "<string>", line 3, in error_prompt^M
RuntimeError: Python exception called^M
(gdb) FAIL: gdb.python/python.exp: set the hook to default
...
The problem is that gdb_test_multiple here:
...
gdb_test_multiple "python gdb.prompt_hook = error_prompt" "set the hook" {
-re "Python Exception (exceptions.RuntimeError|<(type 'exceptions.|class ')RuntimeError'>) Python excepti
on called.*" {
pass "set hook"
}
}
...
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.*" {
pass "set hook"
}
}
...
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.
Fix the regexps in both gdb_test_multiple calls.
Tested on x86_64-linux.
gdb/testsuite/ChangeLog:
2019-07-29 Tom de Vries <tdevries@suse.de>

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
gdb.InferiorThread.handle method. I had initially named it "thread_handle"
but Tom Tromey suggested just "handle".

I have some code which uses these functions. I very much like the

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.

The str () function, called on a gdb.Value instance, produces a string
representation similar to what can be achieved with the print command,
but it doesn't allow to specify additional formatting settings, for
instance disabling pretty printers.
This patch introduces a new format_string () method to gdb.Value which
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.

display_hint.

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.
gdb/testsuite/ChangeLog:
* gdb.python/py-prettyprint.exp: Use gdb_breakpoint and
gdb_continue_to_breakpoint more throughout this test.
(run_lang_tests) Supply unique test names, and use

A while back I typed "info pretty-printers" with a large number of
printers installed, and I typed "q" to stop the pagination. I noticed
that gdb printed a Python exception in this case.
It seems to me that, instead, quitting pagination (or control-c'ing a
Python command generally) should be handled the same way that gdb
normally handles a quit.
This patch implements this idea by changing gdbpy_handle_exception to
treat PyExc_KeyboardInterrupt specially.

Since commit
56bcdbea2bed ("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
gdb prompt. readline_is_used then reads in the prompt causing it to fail
and the final chunk of tests to be skipped.
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
no frame.)
This patch adds Inferior.architecture to allow this. Normally I think
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
consistency.

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.
After this change the output from "./gdb -iex 'set complaint 1' -nx ./gdb"
reads:

PR python/18170 questions why it's not possible to convert a pointer

Digging a bit shows that the Python 2.7 int() constructor will happily
return a long in some cases. And, it seems gdb already understands

Since commit
56bcdbea2bed ("Let gdb.execute handle multi-line commands")
trying to use a command like gdb.execute("show commands") in Python
fails. GDB ends up trying to run the "commands" command.
The reason is that GDB gets confused with the special "commands"
command. In process_next_line, the lookup_cmd_1 function returns the
cmd_list_element representing the "commands" sub-command of "show".
Lower, we check the cmd_list_element to see if it matches various
control commands by name, including the "commands" command. This is
where we wrongfully conclude that the executed command must be
"commands", when in reality it was "show commands".
The fix proposed in this patch removes the comparisons by name, instead
comparing the cmd_list_element object by pointer with the objects
created at initialization time.
Tested on the buildbot, though on a single builder (Fedora-x86_64-m64).

Printing a GDB Python object is notoriously not helpful:
>>> print(gdb.selected_inferior())
<gdb.Inferior object at 0x7fea59aed198>
>>> print(gdb.objfiles())
[<gdb.Objfile object at 0x7fea59b57c90>]
This makes printing debug traces more difficult than it should be. This
patch provides some repr() implementation for these two types (more to
come if people agree with the idea, but I want to test the water first).
Here's the same example as above, but with this patch:
>>> print(gdb.selected_inferior())
<gdb.Inferior num=1>
>>> print(gdb.objfiles())
[<gdb.Objfile filename=/home/emaisin/build/binutils-gdb-gcc-git/gdb/test>]
I implemented repr rather than str, because when printing a list (or
another container I suppose), Python calls the repr method of the
elements. This is useful when printing a list of inferiors or objfiles.
The print(gdb.objfiles()) above would not have worked if I had
implemented str.

str:

anymore. We expect an exception to be thrown.
gdb/testsuite/ChangeLog:
* gdb.python/py-inferior.exp: Test using an invalid gdb.Inferior
object.

I noticed that the py-prettyprint.exp test names were not unique.
This patch fixes the problem via with_test_prefix.

PR python/16047 points out that, while the documentation says that the
to_string method is optional for a pretty-printer, the code disagrees
and throws an exception. This patch fixes the problem. varobj is
already ok here.
Tested on x86-64 Fedora 26.

Commit 6d52907e226a (MI: Print frame architecture when printing frames
on an MI channel) added frame's architecture to MI frame output. However
the frame architecture was not correctly printed in the output of
"-stack-list-frames" with frame filters enabled (via "-enable-frame-filters").
This was because with frame filters enabled, the actual frame printing is
done in "py_print_frame" rather than "print_frame". This issue is now fixed.
gdb/Changelog:

* python/py-framefilter.c (py_print_frame): Print frame architecture
when printing on an MI output.
gdb/testsuite/Changelog:

* gdb.python/py-framefilter-mi.exp: Update regexp to
check for "arch" field in frame output.

This fails for me on openSUSE leap 15.0:
...
FAIL: gdb.python/py-rbreak.exp: check number of returned breakpoints is 11
...
The rbreak "" command expects 11 breaks, but I see two extra for
__libc_csu_fini and __libc_csu_init:
...
Breakpoint 13 at 0x4005b0: file elf-init.c, line 106.^M
Breakpoint 14 at 0x400540: file elf-init.c, line 68.^M
...
This patch fixes the failing test by excluding functions starting with an
underscore.
Tested on x86_64-linux.

Invoking -var-info-path-expression on a dynamic varobj lead either in wrong
(nonsense) result or to a segmentation fault in cplus_describe_child().
This was caused by the fact that varobj_get_path_expr() called
cplus_path_expr_of_child() ignoring the fact the parent of the variable
is dynamic. Then, cplus_describe_child() accessed the underlaying C type
members by index, causing (i) either wrong (nonsense) expression being
returned (since dynamic child may be completely arbibtrary value)
or (ii) segmentation fault (in case the index higher than number of
underlaying C type members.
This fixes the problem by checking whether a varobj is a child of a dynamic
varobj and, if so, reporting an error as described in documentation.
gdb/ChangeLog:
* varobj.c (varobj_get_path_expr_parent): Report an error if
parent is a dynamic varobj.
gdb/testsuite/Changelog:
* gdb.python/py-mi-var-info-path-expression.c: New file.
* gdb.python/py-mi-var-info-path-expression.py: New file.
* gdb.python/py-mi-var-info-path-expression.exp: New file.
