Benno Fünfstück	1c97054b87	Make command-repeat work after gdb.execute 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). gdb/ChangeLog: PR python/23714 * gdb/python/python.c (execute_gdb_command): Call prevent_dont_repeat earlier to avoid affecting dont_repeat. gdb/testuite/ChangeLog: PR python/23714 * gdb.python/python.exp: Test command repetition after gdb.execute.	8 years ago

Tom Tromey	39a24317ac	Report Python errors coming from gdb.post_event PR python/14062 points out that errors coming from the gdb.post_event callback are not reported.

Simon Marchi	8588b35692	python: Make gdb.execute("show commands") work (PR 23669) Since commit `56bcdbea2b` ("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). gdb/ChangeLog: PR python/23669 * breakpoint.c (commands_cmd_element): New.

Tom Tromey	12973681f5	Use counted_command_line everywhere Currently command lines are reference counted using shared_ptr only when attached to breakpoints. This patch changes gdb to use shared_ptr in commands as well. This allows for the removal of copy_command_lines. Note that the change to execute_user_command explicitly makes a new reference to the command line. This will be used in a later patch. This simplifies struct command_line based on the observation that a given command can have at most two child bodies: an "if" can have both "then" and "else" parts. Perhaps the names I've chosen for the replacements here are not very good -- your input requested.

Simon Marchi	ba18742c3a	C++ify xmethod_worker, get rid of VEC(xmethod_worker_ptr) The initial goal of this patch was to remove the usage of VEC(xmethod_worker_ptr) and corresponding cleanups. I ended up having to C++ify the xmethod_worker code, to be able to have xmethod_workers free their data in destructors, and therefore be able to use vectors of xmethod_worker unique_ptr. The operations in extension_language_ops that act on one instance of xmethod_worker (get result type, get args type, invoke) are transformed to methods of xmethod_worker. xmethod_worker becomes an abstract base class with virtual pure methods which python_xmethod_worker implements. The only xmethod-related operation left in extension_language_ops is get_matching_xmethod_workers, which returns a list of xmethod_workers. The changes are relatively straightforward, but here are some notes on things that may raise eyebrows: - I was not really comfortable with the value_of_xmethod function. At first it looks like a simple getter, so I considered making it a method of xmethod_worker. But actually it creates a value and transfers the ownership of the xmethod_worker to it. It would be a bit weird and error-prone if calling a method on an object silently removed the ownership of the object from the caller. To reflect the behavior more accurately, I renamed it to value_from_xmethod and made it accept an rvalue-reference (so the caller knows it gives away the ownership). I noticed the backlink from xmethod_worker to its owning value was not used, so I removed it. - Some code, like get_matching_xmethod_workers, made each callee fill a new vector, which was then merged in the result vector. I think it's safe if we always pass the same vector around, and each implementation just appends to it. - The clone operation does not seem particularly useful, it is removed in the following patch. gdb/ChangeLog: * extension-priv.h (enum ext_lang_rc): Remove, move to extension.h.

Pedro Alves	a20714ff39	Make "break foo" find "A::foo", A::B::foo", etc. [C++ and wild matching] This patch teaches GDB about setting breakpoints in all scopes (namespaces and classes) by default. Here's a contrived example: (gdb) b func<tab> (anonymous namespace)::A::function() Bn::(anonymous namespace)::B::function() function(int, int) (anonymous namespace)::B::function() Bn::(anonymous namespace)::function() gdb::(anonymous namespace)::A::function() (anonymous namespace)::B::function() const Bn::(anonymous namespace)::function(int, int) gdb::(anonymous namespace)::function() (anonymous namespace)::function() Bn::B::func() gdb::(anonymous namespace)::function(int, int) (anonymous namespace)::function(int, int) Bn::B::function() gdb::A::func() A::func() Bn::func() gdb::A::function() A::function() Bn::function() gdb::func() B::func() Bn::function(int, int) gdb::function() B::function() Bn::function(long) gdb::function(int, int) B::function() const func() gdb::function(long) B::function_const() const function() (gdb) b function Breakpoint 1 at 0x4005ce: function. (26 locations) (gdb) b B::function<tab> (anonymous namespace)::B::function() B::function() const Bn::B::function() (anonymous namespace)::B::function() const B::function_const() const B::function() Bn::(anonymous namespace)::B::function() (gdb) b B::function Breakpoint 1 at 0x40072c: B::function. (6 locations) To get back the original behavior of interpreting the function name as a fully-qualified name, you can use the new "-qualified" (or "-q") option/flag (added by this commit). For example: (gdb) b B::function (anonymous namespace)::B::function() B::function() const Bn::B::function() (anonymous namespace)::B::function() const B::function_const() const B::function() Bn::(anonymous namespace)::B::function() vs: (gdb) b -qualified B::function B::function() B::function() const B::function_const() const I've chosen "-qualified" / "-q" because "-f" (for "full" or "fully-qualified") is already taken for "-function". Note: the "-qualified" option works with both linespecs and explicit locations. I.e., these are equivalent: (gdb) b -q func (gdb) b -q -f func and so are these: (gdb) b -q filename.cc:func (gdb) b -q -s filename.cc -f func (gdb) b -s filename.cc -q -f func (gdb) b -s filename.cc -f func -q To better understand why I consider wild matching the better default, consider what happens when we get to the point when _all_ of GDB is wrapped under "namespace gdb {}". I have a patch series that does that, and when I started debugging that GDB, I immediately became frustrated. You'd have to write "b gdb::internal_error", "b gdb::foo", "b gdb::bar", etc. etc., which gets annoying pretty quickly. OTOH, consider how this makes it very easy to set breakpoints in classes wrapped in anonymous namespaces. You just don't think of them, GDB finds the symbols for you automatically. (At the Cauldron a couple months ago, several people told me that they run into a similar issue when debugging other C++ projects. One example was when debugging LLVM, which puts all its code under the "llvm" namespace.) Implementation-wise, what the patch does is: - makes C++ symbol name hashing only consider the last component of a symbol name. (so that we can look up symbol names by last-component name only). - adds a C++ symbol name matcher for symbol_name_match_type::WILD, which ignores missing leading specifiers / components. - adjusts a few preexisting testsuite tests to use "-qualified" when they mean it. - adds new testsuite tests. - adds unit tests. Grows the gdb.linespec/ tests like this: -# of expected passes 7823 +# of expected passes 8977 gdb/ChangeLog: 2017-11-29 Pedro Alves <palves@redhat.com> * NEWS: Mention that breakpoints on C++ functions are now set on on all namespaces/classes by default, and mention "break -qualified". * ax-gdb.c (agent_command_1): Adjust to pass a symbol_name_match_type to new_linespec_location. * breakpoint.c (parse_breakpoint_sals): Adjust to get_linespec_location's return type change.

Simon Marchi	e8e7d10c39	python: Fix memleak in do_start_initialization While playing with valgrind, I noticed that with Python 3, the progname variable in do_start_initialization is not being freed (concat returns a malloc'ed string). This patch uses unique_xmalloc_ptr to manage it. With Python 2, we pass progname it directly to Py_SetProgramName, so it should not be freed. We therefore release it before passing it. gdb/ChangeLog: * python/python.c (do_start_initialization): Change progname type to gdb::unique_xmalloc_ptr.

Tom Tromey	981a3fb359	Constify add_prefix_cmd This changes add_prefix_cmd to accept a const-taking function as an argument; then fixes up all the callers. In a couple of spots I had to add a non-const overload of a function, because the function is passed to two different command-adding "constructors". These overloads are temporary; once constification is complete they can be removed. This patch also fixes a typo I happened to notice while constifying. Note that this touches a couple of files (gnu-nat.c and go32-nat.c) that I can't build. So, while I made a best-effort there, I am not certain they will still compile.

Tom Tromey	7d221d749c	Make it simpler to add events to Python The first patch in this series went through several iterations as I'd forgotten how many places had to be touched to add a new event and a new event type. This patch simplifies the process using two new ".def" files. Now, a new event type can be added by adding a line to "py-event-types.def", and a new event registry can be added by adding a line to "py-all-events.def".

Pedro Alves	6c5b2ebeac	struct symtabs_and_lines -> std::vector<symtab_and_line> This replaces "struct symtabs_and_lines" with std::vector<symtab_and_line> in most cases. This removes a number of cleanups. In some cases, the sals objects do not own the sals they point at. Instead they point at some sal that lives on the stack. Typically something like this: struct symtab_and_line sal; struct symtabs_and_lines sals; // fill in sal sals.nelts = 1; sals.sals = &sal; // use sals Instead of switching those cases to std::vector too, such usages are replaced by gdb::array_view<symtab_and_line> instead. This avoids introducing heap allocations. gdb/ChangeLog: 2017-09-04 Pedro Alves <palves@redhat.com> * ax-gdb.c (agent_command_1): Use range-for. * break-catch-throw.c (re_set_exception_catchpoint): Update. * breakpoint.c: Include "common/array-view.h".

Tom Tromey	ffc2605c41	Introduce event_location_up This removes make_cleanup_delete_event_location and instead changes the various location functions to return an event_location_up, a new unique_ptr typedef. This is largely straightforward, but be sure to examine the init_breakpoint_sal change. I believe the code I deleted there is dead, because "location != NULL" can never be true in that branch; but you should double-check. gdb/ChangeLog 2017-04-12 Tom Tromey <tom@tromey.com> * tracepoint.c (scope_info): Update. * spu-tdep.c (spu_catch_start): Update. * python/python.c (gdbpy_decode_line): Update. * python/py-finishbreakpoint.c (bpfinishpy_init): Update. * python/py-breakpoint.c (bppy_init): Update. * probe.c (parse_probes): Update. * mi/mi-cmd-break.c (mi_cmd_break_insert_1): Update. * location.h (event_location_deleter): New struct.

Pedro Alves	2adadf5170	-Wwrite-strings: Add a PyArg_ParseTupleAndKeywords "const char " overload -Wwrite-strings flags code like: static char keywords[] = {"command", "from_tty", "to_string", NULL }; as needing "(char )" casts, because string literals are "const char []". We can get rid of the casts by changing the array type like this: - static char keywords[] = {"command", "from_tty", "to_string", NULL }; + static const char keywords[] = {"command", "from_tty", "to_string", NULL }; However, passing the such array to PyArg_ParseTupleAndKeywords no longer works OOTB, because PyArg_ParseTupleAndKeywords expects a "char ": PyArg_ParseTupleAndKeywords(PyObject args, PyObject kw, const char format, char keywords[], ...); and "const char " is not implicitly convertible to "char ". C++ is more tolerant that C here WRT aliasing, and a const_cast<char > is fine. However, to avoid having all callers do the cast themselves, this commit defines a gdb_PyArg_ParseTupleAndKeywords function here with a corresponding 'keywords' parameter type that does the cast in a single place. gdb/ChangeLog: 2017-04-05 Pedro Alves <palves@redhat.com> python/python-internal.h (gdb_PyArg_ParseTupleAndKeywords): New static inline function. * python/py-arch.c (archpy_disassemble): Constify 'keywords' array and use gdb_PyArg_ParseTupleAndKeywords. * python/py-cmd.c (cmdpy_init): Likewise. * python/py-finishbreakpoint.c (bpfinishpy_init): Likewise. * python/py-inferior.c (infpy_read_memory, infpy_write_memory) (infpy_search_memory): Likewise. * python/py-objfile.c (objfpy_add_separate_debug_file) (gdbpy_lookup_objfile): Likewise. * python/py-symbol.c (gdbpy_lookup_symbol) (gdbpy_lookup_global_symbol): Likewise. * python/py-type.c (gdbpy_lookup_type): Likewise. * python/py-value.c (valpy_lazy_string, valpy_string): Likewise. * python/python.c (execute_gdb_command, gdbpy_write, gdbpy_flush): Likewise.	9 years ago

Andreas Arnez	1a5e158b68	Remove constness of libdir in do_start_initialization The patch "Fix memory leak in python.c:do_start_initialization" (https://sourceware.org/ml/gdb-patches/2017-03/msg00407.html) introduced a compilation error on some platforms: ../../binutils-gdb/gdb/python/python.c: In function bool do_start_initialization(): ../../binutils-gdb/gdb/python/python.c:1556:16: error: invalid conversion from const void* to void* [-fpermissive] xfree (libdir); ^ This is fixed by removing the constness of libdir's data type. gdb/ChangeLog: * python/python.c (do_start_initialization): Remove 'const' from data type of libdir.	9 years ago
Philipp Rudo	3f2a3564b1	Fix memory leak in python.c:do_start_initialization When intializing Python the path to the python binary is build the following way progname = concat (ldirname (python_libdir), SLASH_STRING, "bin", SLASH_STRING, "python", (char *) NULL); This is problematic as both concat and ldirname allocate memory for the string they return. Thus the memory allocated by ldirname cannot be accessed afterwards causing a memory leak. Fix it by temporarily storing libdir in a variable and xfree it after concat. gdb/ChangeLog: python/python.c (do_start_initialization): Fix memory leak.	9 years ago
