2024-05-10Implement tp_richcompare for gdb.BlockTom Tromey1-1/+23
I noticed that two gdb.Block objects will never compare as equal with '=='. This patch fixes the problem by implementing tp_richcompare, as was done for gdb.Frame.
2024-03-26gdb, gdbserver, gdbsupport: remove includes of early headersSimon Marchi1-1/+0
Now that defs.h, server.h and common-defs.h are included via the `-include` option, it is no longer necessary for source files to include them. Remove all the inclusions of these files I could find. Update the generation scripts where relevant. Change-Id: Ia026cff269c1b7ae7386dd3619bc9bb6a5332837 Approved-By: Pedro Alves <pedro@palves.net>
2024-01-12Update copyright year range in header of all files managed by GDBAndrew Burgess1-1/+1
This commit is the result of the following actions: - Running gdb/copyright.py to update all of the copyright headers to include 2024, - Manually updating a few files the copyright.py script told me to update, these files had copyright headers embedded within the file, - Regenerating gdbsupport/Makefile.in to refresh it's copyright date, - Using grep to find other files that still mentioned 2023. If these files were updated last year from 2022 to 2023 then I've updated them this year to 2024. I'm sure I've probably missed some dates. Feel free to fix them up as you spot them.
2024-01-12gdb/python: hoist common invalid object repr code into py-utils.cAndrew Burgess1-1/+1
Many object types now have a __repr__() function implementation. A common pattern is that, if an object is invalid, we print its representation as: <TYPENAME (invalid)>. I thought it might be a good idea to move the formatting of this specific representation into a utility function, and then update all of our existing code to call the new function. The only place where I haven't made use of the new function is in unwind_infopy_repr, where we currently return a different string. This case is a little different as the UnwindInfo is invalid because it references a frame, and it is the frame itself which is invalid. That said, I think it would be fine to switch to using the standard format; if the UnwindInfo references an invalid frame, then the UnwindInfo is itself invalid. But changing this would be an actual change in behaviour, while all the other changes in this commit are just refactoring. Approved-By: Tom Tromey <tom@tromey.com>
2023-07-04gdb: add __repr__() implementation to a few Python typesMatheus Branco Borella1-1/+36
Only a few types in the Python API currently have __repr__() implementations. This patch adds a few more of them. specifically: it adds __repr__() implementations to gdb.Symbol, gdb.Architecture, gdb.Block, gdb.Breakpoint, gdb.BreakpointLocation, and gdb.Type. This makes it easier to play around the GDB Python API in the Python interpreter session invoked with the 'pi' command in GDB, giving more easily accessible tipe information to users. An example of how this would look like: (gdb) pi >> gdb.lookup_type("char") <gdb.Type code=TYPE_CODE_INT name=char> >> gdb.lookup_global_symbol("main") <gdb.Symbol print_name=main> The gdb.Block.__repr__() method shows the first 5 symbols from the block, and then a message to show how many more were elided (if any).
2023-05-05gdb/python: add mechanism to manage Python initialization functionsAndrew Burgess1-1/+3
Currently, when we add a new python sub-system to GDB, e.g. py-inferior.c, we end up having to create a new function like gdbpy_initialize_inferior, which then has to be called from the function do_start_initialization in python.c. In some cases (py-micmd.c and py-tui.c), we have two functions gdbpy_initialize_*, and gdbpy_finalize_*, with the second being called from finalize_python which is also in python.c. This commit proposes a mechanism to manage these initialization and finalization calls, this means that adding a new Python subsystem will no longer require changes to python.c or python-internal.h, instead, the initialization and finalization functions will be registered directly from the sub-system file, e.g. py-inferior.c, or py-micmd.c. The initialization and finalization functions are managed through a new class gdbpy_initialize_file in python-internal.h. This class contains a single global vector of all the initialization and finalization functions. In each Python sub-system we create a new gdbpy_initialize_file object, the object constructor takes care of registering the two callback functions. Now from python.c we can call static functions on the gdbpy_initialize_file class which take care of walking the callback list and invoking each callback in turn. To slightly simplify the Python sub-system files I added a new macro GDBPY_INITIALIZE_FILE, which hides the need to create an object. We can now just do this: GDBPY_INITIALIZE_FILE (gdbpy_initialize_registers); One possible problem with this change is that there is now no guaranteed ordering of how the various sub-systems are initialized (or finalized). To try and avoid dependencies creeping in I have added a use of the environment variable GDB_REVERSE_INIT_FUNCTIONS, this is the same environment variable used in the generated init.c file. Just like with init.c, when this environment variable is set we reverse the list of Python initialization (and finalization) functions. As there is already a test that starts GDB with the environment variable set then this should offer some level of protection against dependencies creeping in - though for full protection I guess we'd need to run all gdb.python/*.exp tests with the variable set. I have tested this patch with the environment variable set, and saw no regressions, so I think we are fine right now. One other change of note was for gdbpy_initialize_gdb_readline, this function previously returned void. In order to make this function have the correct signature I've updated its return type to int, and we now return 0 to indicate success. All of the other initialize (and finalize) functions have been made static within their respective sub-system files. There should be no user visible changes after this commit.

2023-02-19Convert block_static_block and block_global_block to methodsTom Tromey1-2/+2
This converts block_static_block and block_global_block to be methods. This was mostly written by script. It was simpler to convert them at the same time because they're often used near each other.
2023-01-01Update copyright year range in header of all files managed by GDBJoel Brobecker1-1/+1
This commit is the result of running the gdb/copyright.py script, which automated the update of the copyright year range for all source files managed by the GDB project to be updated to include year 2023.
2022-07-28Rewrite registry.hTom Tromey1-42/+28
This rewrites registry.h, removing all the macros and replacing it with relatively ordinary template classes. The result is less code than the previous setup. It replaces large macros with a relatively straightforward C++ class, and now manages its own cleanup. The existing type-safe "key" class is replaced with the equivalent template class. This approach ended up requiring relatively few changes to the users of the registry code in gdb -- code using the key system just required a small change to the key's declaration. All existing users of the old C-like API are now converted to use the type-safe API. This mostly involved changing explicit deletion functions to be an operator() in a deleter class. The old "save/free" two-phase process is removed, and replaced with a single "free" phase. No existing code used both phases. The old "free" callbacks took a parameter for the enclosing container object. However, this wasn't truly needed and is removed here as well.

2021-09-09gdb/python: remove all uses of Py_TPFLAGS_HAVE_ITERAndrew Burgess1-2/+2
Python 2 has a bit flag Py_TPFLAGS_HAVE_ITER which can be passed as part of the tp_flags field when defining a new object type. This flag is not defined in Python 3 and so we define it to 0 in python-internal.h (when IS_PY3K is defined). The meaning of this flag is that the object has the fields tp_iter and tp_iternext. Note the use of "has" here, the flag says nothing about the values in those fields, just that the type object has the fields. In early versions of Python 2 these fields were no part of the PyTypeObject struct, they were added in version 2.2 (see https://docs.python.org/release/2.3/api/type-structs.html). And so, there could be a some code compiled out there which has a PyTypeObject structure within it that doesn't even have the tp_iter and tp_iternext fields, attempting to access these fields would be undefined behaviour. And so Python added the Py_TPFLAGS_HAVE_ITER flag. If the flag is present then Python is free to access the tp_iter and tp_iternext fields. If we consider GDB then we always assume that the tp_iter and tp_iternext fields are part of PyTypeObject. If someone was crazy enough to try and compile GDB against Python 2.1 then we'd get lots of build errors saying that we were passing too many fields when initializing PyTypeObject structures. And so, I claim, we can be sure that GDB will always be compiled with a version of Python that has the tp_iter and tp_iternext fields in PyTypeObject. Next we can look at the Py_TPFLAGS_DEFAULT flag. In Python 2, each time additional fields are added to PyTypeObject a new Py_TPFLAGS_* flag would be defined to indicate whether those flags are present or not. And, those new flags would be added to Py_TPFLAGS_DEFAULT. And so, in the latest version of Python 2 the Py_TPFLAGS_DEFAULT flag includes Py_TPFLAGS_HAVE_ITER (see https://docs.python.org/2.7/c-api/typeobj.html). In GDB we pass Py_TPFLAGS_DEFAULT as part of the tp_flags for all objects we define. And so, in this commit, I propose to remove all uses of Py_TPFLAGS_HAVE_ITER from GDB, it's simply not needed. There should be no user visible changes after this commit.
2021-04-28gdb: delay python initialisation until gdbpy_finish_initializationAndrew Burgess1-6/+11
Delay Python initialisation until gdbpy_finish_initialization. This is mostly about splitting the existing gdbpy_initialize_* functions in two, all the calls to register_objfile_data_with_cleanup, gdbarch_data_register_post_init, etc are moved into new _initialize_* functions, but everything else is left in the gdbpy_initialize_* functions. Then the call to do_start_initialization (in python/python.c) is moved from the _initialize_python function into gdbpy_finish_initialization. There should be no user visible changes after this commit. gdb/ChangeLog: * python/py-arch.c (_initialize_py_arch): New function.

2020-12-04Remove redundant typedefsTom Tromey1-8/+8
I was inspired by this patch of Simon's: https://sourceware.org/pipermail/gdb-patches/2020-November/173522.html ... to remove other typedefs that are no longer necessary now that gdb uses C++. I didn't remove absolutely every one -- I didn't touch the tdep files. However, I removed many of them.

2017-04-05-Wwrite-strings: Wrap PyGetSetDef for construction with string literalsPedro Alves1-1/+1
Unfortunately, PyGetSetDef's 'name' and 'doc' members are 'char *' instead of 'const char *', meaning that in order to list-initialize PyGetSetDef arrays using string literals requires writing explicit 'char *' casts. For example: static PyGetSetDef value_object_getset[] = { - { "address", valpy_get_address, NULL, "The address of the value.", + { (char *) "address", valpy_get_address, NULL, + (char *) "The address of the value.", NULL }, - { "is_optimized_out", valpy_get_is_optimized_out, NULL, - "Boolean telling whether the value is optimized " + { (char *) "is_optimized_out", valpy_get_is_optimized_out, NULL, + (char *) "Boolean telling whether the value is optimized " "out (i.e., not available).", NULL }, - { "type", valpy_get_type, NULL, "Type of the value.", NULL }, - { "dynamic_type", valpy_get_dynamic_type, NULL, - "Dynamic type of the value.", NULL }, - { "is_lazy", valpy_get_is_lazy, NULL, - "Boolean telling whether the value is lazy (not fetched yet\n\ + { (char *) "type", valpy_get_type, NULL, + (char *) "Type of the value.", NULL }, + { (char *) "dynamic_type", valpy_get_dynamic_type, NULL, + (char *) "Dynamic type of the value.", NULL }, + { (char *) "is_lazy", valpy_get_is_lazy, NULL, + (char *) "Boolean telling whether the value is lazy (not fetched yet\n\ from the inferior). A lazy value is fetched when needed, or when\n\ the \"fetch_lazy()\" method is called.", NULL }, {NULL} /* Sentinel */ We have ~20 such arrays, and I first wrote a patch that fixed all of them like that... It's not pretty... One way to make these a bit less ugly would be add a new macro that hides the casts, like: #define GDBPY_GSDEF(NAME, GET, SET, DOC, CLOSURE) \ { (char *) NAME, GET, SET, (char *) DOC, CLOSURE } and then use it like: static PyGetSetDef value_object_getset[] = { GDBPY_GSDEF ("address", valpy_get_address, NULL, "The address of the value.", NULL), GDBPY_GSDEF ("is_optimized_out", valpy_get_is_optimized_out, NULL, "Boolean telling whether the value is optimized ", NULL), {NULL} /* Sentinel */ }; But since we have C++11, which gives us constexpr and list initialization, I thought of a way that requires no changes where the arrays are initialized: We add a new type that extends PyGetSetDef (called gdb_PyGetSetDef), and add constexpr constructors that accept const 'name' and 'doc', and then list/aggregate initialization simply "calls" these matching constructors instead. I put "calls" in quotes, because given "constexpr", it's all done at compile time, and there's no overhead either in binary size or at run time. In fact, we get identical binaries, before/after this change. Unlike the fixes that fix some old Python API to match the API of more recent Python, this switches to using explicit "gdb_PyGetSetDef" everywhere, just to be clear that we are using our own version of it. gdb/ChangeLog: 2017-04-05 Pedro Alves <palves@redhat.com> * python/python-internal.h (gdb_PyGetSetDef): New type. * python/py-block.c (block_object_getset) (breakpoint_object_getset): Now a gdb_PyGetSetDef array. * python/py-event.c (event_object_getset) (finish_breakpoint_object_getset): Likewise. * python/py-inferior.c (inferior_object_getset): Likewise. * python/py-infthread.c (thread_object_getset): Likewise. * python/py-lazy-string.c (lazy_string_object_getset): Likewise. * python/py-linetable.c (linetable_entry_object_getset): Likewise. * python/py-objfile.c (objfile_getset): Likewise. * python/py-progspace.c (pspace_getset): Likewise. * python/py-record-btrace.c (btpy_insn_getset, btpy_call_getset): Likewise. * python/py-record.c (recpy_record_getset): Likewise. * python/py-symbol.c (symbol_object_getset): Likewise. * python/py-symtab.c (symtab_object_getset, sal_object_getset): Likewise. * python/py-type.c (type_object_getset, field_object_getset): Likewise. * python/py-value.c (value_object_getset): Likewise.

This patch splits the TRY_CATCH macro into three, so that we go from this: ~~~ volatile gdb_exception ex; TRY_CATCH (ex, RETURN_MASK_ERROR) { } if (ex.reason < 0) { } ~~~ to this: ~~~ TRY { } CATCH (ex, RETURN_MASK_ERROR) { } END_CATCH ~~~ Thus, we'll be getting rid of the local volatile exception object, and declaring the caught exception in the catch block. This allows reimplementing TRY/CATCH in terms of C++ exceptions when building in C++ mode, while still allowing to build GDB in C mode (using setjmp/longjmp), as a transition step. TBC, after this patch, is it _not_ valid to have code between the TRY and the CATCH blocks, like: TRY { } // some code here. CATCH (ex, RETURN_MASK_ERROR) { } END_CATCH Just like it isn't valid to do that with C++'s native try/catch. By switching to creating the exception object inside the CATCH block scope, we can get rid of all the explicitly allocated volatile exception objects all over the tree, and map the CATCH block more directly to C++'s catch blocks. The majority of the TRY_CATCH -> TRY+CATCH+END_CATCH conversion was done with a script, rerun from scratch at every rebase, no manual editing involved. After the mechanical conversion, a few places needed manual intervention, to fix preexisting cases where we were using the exception object outside of the TRY_CATCH block, and cases where we were using "else" after a 'if (ex.reason) < 0)' [a CATCH after this patch]. The result was folded into this patch so that GDB still builds at each incremental step. END_CATCH is necessary for two reasons: First, because we name the exception object in the CATCH block, which requires creating a scope, which in turn must be closed somewhere. Declaring the exception variable in the initializer field of a for block, like: #define CATCH(EXCEPTION, mask) \ for (struct gdb_exception EXCEPTION; \ exceptions_state_mc_catch (&EXCEPTION, MASK); \ EXCEPTION = exception_none) would avoid needing END_CATCH, but alas, in C mode, we build with C90, which doesn't allow mixed declarations and code. Second, because when TRY/CATCH are wired to real C++ try/catch, as long as we need to handle cleanup chains, even if there's no CATCH block that wants to catch the exception, we need for stop at every frame in the unwind chain and run cleanups, then rethrow. That will be done in END_CATCH. After we require C++, we'll still need TRY/CATCH/END_CATCH until cleanups are completely phased out -- TRY/CATCH in C++ mode will save/restore the current cleanup chain, like in C mode, and END_CATCH catches otherwise uncaugh exceptions, runs cleanups and rethrows, so that C++ cleanups and exceptions can coexist. IMO, this still makes the TRY/CATCH code look a bit more like a newcomer would expect, so IMO worth it even if we weren't considering C++. gdb/ChangeLog. 2015-03-07 Pedro Alves <palves@redhat.com> * common/common-exceptions.c (struct catcher) <exception>: No longer a pointer to volatile exception.

2015-02-11Fix redefinition errors in C++ modeTom Tromey1-2/+2
In C, we can forward declare static structure instances. That doesn't work in C++ though. C++ treats these as definitions. So then the compiler complains about symbol redefinition, like: src/gdb/elfread.c:1569:29: error: redefinition of ‘const sym_fns elf_sym_fns_lazy_psyms’ src/gdb/elfread.c:53:29: error: ‘const sym_fns elf_sym_fns_lazy_psyms’ previously declared here The intent of static here is naturally to avoid making these objects visible outside the compilation unit. The equivalent in C++ would be to instead define the objects in the anonymous namespace. But given that it's desirable to leave the codebase compiling as both C and C++ for a while, this just makes the objects extern. (base_breakpoint_ops is already declared in breakpoint.h, so we can just remove the forward declare from breakpoint.c) gdb/ChangeLog: 2015-02-11 Tom Tromey <tromey@redhat.com> Pedro Alves <palves@redhat.com> * breakpoint.c (base_breakpoint_ops): Delete. * dwarf2loc.c (dwarf_expr_ctx_funcs): Make extern. * elfread.c (elf_sym_fns_gdb_index, elf_sym_fns_lazy_psyms): Make extern. * guile/guile.c (guile_extension_script_ops, guile_extension_ops): Make extern. * ppcnbsd-tdep.c (ppcnbsd2_sigtramp): Make extern. * python/py-arch.c (arch_object_type): Make extern. * python/py-block.c (block_syms_iterator_object_type): Make extern. * python/py-bpevent.c (breakpoint_event_object_type): Make extern. * python/py-cmd.c (cmdpy_object_type): Make extern. * python/py-continueevent.c (continue_event_object_type) * python/py-event.h (GDBPY_NEW_EVENT_TYPE): Remove 'qual' parameter.

2014-11-20Split struct symtab into two: struct symtab and compunit_symtab.Doug Evans1-7/+5
Currently "symtabs" in gdb are stored as a single linked list of struct symtab that contains both symbol symtabs (the blockvectors) and file symtabs (the linetables). This has led to confusion, bugs, and performance issues. This patch is conceptually very simple: split struct symtab into two pieces: one part containing things common across the entire compilation unit, and one part containing things specific to each source file. Example. For the case of a program built out of these files: foo.c foo1.h foo2.h bar.c foo1.h bar.h Today we have a single list of struct symtabs: objfile -> foo.c -> foo1.h -> foo2.h -> bar.c -> foo1.h -> bar.h -> NULL where "->" means the "next" pointer in struct symtab. With this patch, that turns into: objfile -> foo.c(cu) -> bar.c(cu) -> NULL | | v v foo.c bar.c | | v v foo1.h foo1.h | | v v foo2.h bar.h | | v v NULL NULL where "foo.c(cu)" and "bar.c(cu)" are struct compunit_symtab objects, and the files foo.c, etc. are struct symtab objects. So now, for example, when we want to iterate over all blockvectors we can now just iterate over the compunit_symtab list. Plus a lot of the data that was either unused or replicated for each symtab in a compilation unit now lives in struct compunit_symtab. E.g., the objfile pointer, the producer string, etc. I thought of moving "language" out of struct symtab but there is logic to try to compute the language based on previously seen files, and I think that's best left as is for now. With my standard monster benchmark with -readnow (which I can't actually do, but based on my calculations), whereas today the list requires 77MB to store all the struct symtabs, it now only requires 37MB. A modest space savings given the gigabytes needed for all the debug info, etc. Still, it's nice. Plus, whereas today we create a copy of dirname for each source file symtab in a compilation unit, we now only create one for the compunit. So this patch is basically just a data structure reorg, I don't expect significant performance improvements from it. Notes: 1) A followup patch can do a similar split for struct partial_symtab. I have left that until after I get the changes I want in to better utilize .gdb_index (it may affect how we do partial syms). 2) Another followup patch *could* rename struct symtab. The term "symtab" is ambiguous and has been a source of confusion. In this patch I'm leaving it alone, calling it the "historical" name of "filetabs", which is what they are now: just the file-name + line-table. gdb/ChangeLog: Split struct symtab into two: struct symtab and compunit_symtab. * amd64-tdep.c (amd64_skip_xmm_prologue): Fetch producer from compunit. * block.c (blockvector_for_pc_sect): Change "struct symtab *" argument to "struct compunit_symtab *".
