Change install_breakpoint to take a std::unique_ptr
This changes install_breakpoint to take a std::unique_ptr rvalue-ref argument. This makes it clear that install_breakpoint takes ownership of the pointer, and prevents bugs like the one fixed by the previous patch. ChangeLog 2017-08-22 Tom Tromey <tom@tromey.com> * breakpoint.h (install_breakpoint): Update. * breakpoint.c (add_solib_catchpoint): Update.

Fix erroneous cleanup use in add_solib_catchpoint
I happened to notice that add_solib_catchpoint allocated the new catchpoint with "new" but installed a cleanup using "xfree". This patch fixes the bug by changing the function to use std::unique_ptr instead. ChangeLog 2017-08-22 Tom Tromey <tom@tromey.com> * breakpoint.c (add_solib_catchpoint): Use std::unique_ptr. |

Remove save_inferior_ptid
This removes save_inferior_ptid, a cleanup function, in favor of scoped_restore. This also fixes a possible (it seems unlikely that it could happen in practice) memory leak -- save_inferior_ptid should have used make_cleanup_dtor, because it allocated memory. I tested this on the buildbot. However, there are two caveats to this. First, sometimes it seems I misread the results. Second, I think this patch touches some platforms that can't be tested by the buildbot. So, extra care seems warranted. ChangeLog 2017-08-18 Tom Tromey <tom@tromey.com> Pedro Alves <palves@redhat.com> * spu-multiarch.c (parse_spufs_run): Use scoped_restore. * sol-thread.c (sol_thread_resume, sol_thread_wait) (sol_thread_xfer_partial, rw_common): Use scoped_restore. * procfs.c (procfs_do_thread_registers): Use scoped_restore. * proc-service.c (ps_xfer_memory): Use scoped_restore. * linux-tdep.c (linux_corefile_thread): Remove a cleanup.

Use gdb::unique_xmalloc_ptr when calling tilde_expand
This patch changes most sites calling tilde_expand to use gdb::unique_xmalloc_ptr, rather than a cleanup. It also changes scan_expression_with_cleanup to return a unique pointer, because the patch was already touching code in that area. Regression tested on the buildbot.

Introduce and use ui_out_emit_table
This introduces ui_out_emit_table, similar to the other existing ui_out RAII classes, and then uses it in a number of places. This replaces some cleanups.

Introduce class completion_tracker & rewrite completion<->readline interaction
This patch reworks the whole completion machinery, and prepares it for later enhancements. Adds a new "completion_tracker" class that is meant to hold everything about the state of the current completion operation. This class now has the responsibility of tracking the list of completion matches, and checking whether the max completions limit has been reached. You can look at this as this patch starting out by C++fying the existing "completion_tracker" in symtab.c (it's just an htab_t typedef currently), moving it to completer.h/c, and then making it a class/generalizing/enhancing it. Unlike with the current tracking, completion_tracker now checks whether the limit has been reached on each completion match list insertion. This both simplifies the max-completions handling code (maybe_add_completion_enum is gone, for example), and is a prerequisite for follow up patches. The current completion_tracker is only used for symbol completions, and the symbol code gets at the current instance via globals. This patch cleans that up by adding a completion_tracker reference to the signature of the completion functions, and passing the tracker around everywhere necessary. Then, the patch changes how the completion match list is handed over to readline. Currently, we're using the rl_completion_entry_function readline entry point, and the patch switches to rl_attempted_completion_function. A following patch will want to let GDB itself decide the common completion prefix between all matches (what readline calls the "lowest common denominator"), instead of having readline compute it, and that's not possible with the rl_completion_entry_function entry point. Also, rl_attempted_completion_function lets GDB hand over the match list to readline as an array in one go instead of passing down matches one by one, so from that angle it's a nicer entry point anyway. Lastly, the patch catches exceptions around the readline entry points, because we can't let C++ exceptions cross readline. We handle that in the readline input entry point, but the completion entry point isn't guarded, so GDB can abort if completion throws. E.g., in current master: (gdb) b -function "fun<tab> terminate called after throwing an instance of 'gdb_exception_RETURN_MASK_ERROR' Aborted (core dumped) This patch fixes that. This will be exercised in the new tests added later on in the series. gdb/ChangeLog: 2017-07-17 Pedro Alves <palves@redhat.com> * ada-lang.c (symbol_completion_match): Adjust comments.

C++ify breakpoint class hierarchy (destructors only)
Breakpoints are currently in a limbo state between C and C++. There is
a pseudo class hierarchy implemented using struct fields. Taking
watchpoint as an example:
struct watchpoint
{
/* The base class. */
struct breakpoint base;
...
}
and it is instantianted with "new watchpoint ()". When destroyed, a
destructor is first invoked through the breakpoint_ops, and then the
memory is freed by calling delete through a pointer to breakpoint.
Address sanitizer complains about this, for example, because we new and
delete the same memory using different types.
This patch takes the logical step of making breakpoint subclasses extend
the breakpoint class for real, and converts their destructors to actual
C++ destructors.
Regtested on the buildbot.

Create struct type for longjmp breakpoint
The longjmp kind of breakpoint has a destructor, but doesn't have an associated structure. The next patch converts breakpoint destructors from breakpoint_ops::dtor to actual destructors, but to do that it is needed for longjmp_breakpoint to have a structure that will contain such destructor. This patch adds it. According to initialize_breakpoint_ops, a longjmp breakpoint derives from "momentary breakpoints", so eventually a momentary_breakpoint struct/class should probably be created. It's not necessary for the destructor though, so a structure type for this abstract kind of breakpoint can be added when we fully convert breakpoint ops into methods of the breakpoint type hierarchy. It is now necessary to instantiate different kinds of breakpoint objects in set_raw_breakpoint_without_location based on bptype (sometimes a breakpoint, sometimes a longjmp_breakpoint), so it now uses new_breakpoint_from_type to do that. I also changed set_raw_breakpoint to use it, even though I don't think that it can ever receive a bptype that actually requires it. However, I think it's good if all breakpoint object instantion is done in a single place. gdb/ChangeLog: * breakpoint.c (struct longjmp_breakpoint): New struct. (is_tracepoint_type): Change return type to bool. (is_longjmp_type): New function. (new_breakpoint_from_type): Handle longjmp kinds of breakpoints.

Introduce and use new_breakpoint_from_type
This is a small preparatory patch to factor out a snippet that appears twice. More kinds of breakpoints will need to be created based on bptype, so I think it's a good idea to centralize the instantiation of breakpoint objects. gdb/ChangeLog: * breakpoint.c (new_breakpoint_from_type): New function. (create_breakpoint_sal): Use new_breakpoint_from_type and unique_ptr. (create_breakpoint): Likewise. |

Use watchpoint's language when re-parsing expression
PR rust/21484 notes that watch -location does not work with Rust:
(gdb) watch -location a
syntax error in expression, near `) 0x00007fffffffe0f4'.
update_watchpoint tries to tell gdb that the new expression it creates
has C syntax:
/* The above expression is in C. */
b->language = language_c;
However, update_watchpoint doesn't actually use this language when
re-parsing the expression.
Originally I was going to fix this by saving and restoring the
language in update_watchpoint, but this regressed
gdb.dlang/watch-loc.exp, because the constructed expression actually
has D syntax (specifically the name is not parseable by C).
Next I looked at directly constructing an expression, and not relying
on the parser at all; but it seemed to me that upon a re-set, we'd
want to reparse the type, and there is no existing API to do this
correctly.
So, in the end I made a hook to let each language choose what
expression to use. I made all the languages other than Rust use the C
expression, because that is the status quo ante. However, this is
probably not truly correct. After this patch, at least, it is easy to
correct by someone who knows the language(s) in question.
Regtested by the buildbot.

watch_command_1: Fix dangling frame access
While working on some changes to switch_to_thread, I inadvertently make switch_to_thread call reinit_frame_cache more frequently, even when the thread didn't change. This exposed a latent bug in watch_command_1, where we're referencing a frame after creating/inserting breakpoints, which potentially calls reinit_frame_cache if it needs to install breakpoints with a different thread selected. Handle this similarly to how it's already handled in other similar cases. I.e., save any frame-related information we might need before creating a breakpoint. gdb/ChangeLog: 2017-04-13 Pedro Alves <palves@redhat.com> * breakpoint.c (watch_command_1): Save watchpoint-frame info before calling create_internal_breakpoint. |

-Wwrite-strings: Some constification in gdb/breakpoint.c
The main motivation here is avoiding having to write a couple casts
like these:
if (!arg)
- arg = "";
+ arg = (char *) "";
in catch_exception_command_1 and catch_exec_command_1.
That requires making ep_parse_optional_if_clause and
check_for_argument take pointers to const strings. I then tried
propagating the resulting constification all the way, but that was
spiraling out of control, so instead I settled for keeping const and
non-const overloads.

-Wwrite-strings: Don't initialize string command variables to empty string
-Wwrite-strings flags these initializations as requiring a cast.
However, these variables are command variables, and as such point to
heap-allocated memory. The initial allocation is always done when the
corresponding command is registered. E.g.,:
dprintf_function = xstrdup ("printf");
add_setshow_string_cmd ("dprintf-function", class_support,
&dprintf_function, _("\
Set the function to use for dynamic printf"), _("\
Show the function to use for dynamic printf"), NULL,
update_dprintf_commands, NULL,
&setlist, &showlist);
That's why we never reach a bogus attempt to free these string
literals.
So, just drop the incorrect initializations.
gdb/ChangeLog:
2017-04-05 Pedro Alves <palves@redhat.com>
* breakpoint.c (dprintf_function, dprintf_channel): Don't initialize.
* tracepoint.c (default_collect): Don't initialize.

PR gdb/21122: Fix documentation mistakes for breakpoint commands
Currently, the breakpoint documentation refers to some commands taking breakpoint "ranges" as arguments. We discussed this with Pedro and concluded that it would be more accurate to speak in terms of breakpoint "lists", whose elements can optionally be ranges. I also fixed a couple of minor mistakes in the docs. gdb/ChangeLog: * breakpoint.c (_initialize_breakpoint): Update the help description of the 'commands' command to indicate that it takes a list argument. gdb/doc/ChangeLog: * gdb.texinfo (Breakpoints): Reword documentation to speak in terms of space-separated breakpoint lists. Also add a missing @table command and @cindex for breakpoint lists. gdb/testsuite/ChangeLog: * gdb.base/help.exp: Update match pattern for testing 'help commands'. |

Eliminate make_cleanup_ui_file_delete / make ui_file a class hierarchy
This patch starts from the desire to eliminate
make_cleanup_ui_file_delete, but then goes beyond. It makes ui_file &
friends a real C++ class hierarchy, and switches temporary
ui_file-like objects to stack-based allocation.
- mem_fileopen -> string_file
mem_fileopen is replaced with a new string_file class that is treated
as a value class created on the stack. This alone eliminates most
make_cleanup_ui_file_delete calls, and, simplifies code a whole lot
(diffstat shows around 1k loc dropped.)
string_file's internal buffer is a std::string, thus the "string" in
the name. This simplifies the implementation much, compared to
mem_fileopen, which managed growing its internal buffer manually.
- ui_file_as_string, ui_file_strdup, ui_file_obsavestring all gone
The new string_file class has a string() method that provides direct
writable access to the internal std::string buffer. This replaced
ui_file_as_string, which forced a copy of the same data the stream had
inside. With direct access via a writable reference, we can instead
move the string out of the string_stream, avoiding deep string
copying.
Related, ui_file_xstrdup calls are replaced with xstrdup'ping the
stream's string, and ui_file_obsavestring is replaced by
obstack_copy0.
With all those out of the way, getting rid of the weird ui_file_put
mechanism was possible.
- New ui_file::printf, ui_file::puts, etc. methods
These simplify / clarify client code. I considered splitting
client-code changes, like these, e.g.:
- stb = mem_fileopen ();
- fprintf_unfiltered (stb, "%s%s%s",
- _("The valid values are:\n"),
- regdesc,
- _("The default is \"std\"."));
+ string_file stb;
+ stb.printf ("%s%s%s",
+ _("The valid values are:\n"),
+ regdesc,
+ _("The default is \"std\"."));
In two steps, with the first step leaving fprintf_unfiltered (etc.)
calls in place, and only afterwards do a pass to change all those to
call stb.printf etc.. I didn't do that split, because (when I tried),
it turned out to be pointless make-work: the first pass would have to
touch the fprintf_unfiltered line anyway, to replace "stb" with
"&stb".
- gdb_fopen replaced with stack-based objects
This avoids the need for cleanups or unique_ptr's. I.e., this:
struct ui_file *file = gdb_fopen (filename, "w");
if (filename == NULL)
perror_with_name (filename);
cleanups = make_cleanup_ui_file_delete (file);
// use file.
do_cleanups (cleanups);
is replaced with this:
stdio_file file;
if (!file.open (filename, "w"))
perror_with_name (filename);
// use file.
- odd contorsions in null_file_write / null_file_fputs around when to
call to_fputs / to_write eliminated.
- Global null_stream object
A few places that were allocating a ui_file in order to print to
"nowhere" are adjusted to instead refer to a new 'null_stream' global
stream.
- TUI's tui_sfileopen eliminated. TUI's ui_file much simplified
The TUI's ui_file was serving a dual purpose. It supported being used
as string buffer, and supported being backed by a stdio FILE. The
string buffer part is gone, replaced by using of string_file. The
'FILE *' support is now much simplified, by making the TUI's ui_file
inherit from stdio_file.

Remove cleanups from execute_gdb_command
This replaces a cleanup in execute_gdb_command with an instance of std::string. Testing showed that this originally missed a cleanup that was returned by prevent_dont_repeat. This version of the patch changes prevent_dont_repeat to return a scoped_restore rather than a cleanup. 2017-01-10 Tom Tromey <tom@tromey.com> * top.c (prevent_dont_repeat): Change return type. * python/python.c (execute_gdb_command): Use std::string. Update. * guile/guile.c (gdbscm_execute_gdb_command): Update. * command.h (prevent_dont_repeat): Change return type. * breakpoint.c (bpstat_do_actions_1): Update. |

Class-ify ui_out
This patch finalizes the C++ conversion of the ui-out subsystem, by
turning the ui_out and ui_out_impl structures into a single class
hierarchy. ui_out functions are turned into virtual methods of that new
class, so as a result there are a lot of call sites to update.
In the previous version of the patchset, there were separate ui_out and
ui_out_impl classes, but it wasn't really useful and added boilerplate.
In this version there is simply an ui_out base class that is
extended for CLI, TUI and MI.
It's a bit hard to maintain a ChangeLog for such a big patch, I did my
best but I'm sure there are some missing or outdated info in there...

Use ui_file_as_string throughout more
This replaces most of the remaining ui_file_xstrdup calls with ui_file_as_string calls. Whenever a call was replaced, that led to a cascade of other necessary adjustments throughout, to make the code use std::string instead of raw pointers. And then whenever I added a std::string as member of a struct, I needed to adjust allocation/destruction of said struct to use new/delete instead of xmalloc/xfree. The stopping point was once gdb built again. These doesn't seem to be a way to reasonably split this out further. Maybe-not-obvious changes: - demangle_for_lookup returns a cleanup today. To get rid of that, and avoid unnecessary string dupping/copying, this introduces a demangle_result_storage type that the caller instantiates and passes to demangle_for_lookup. - Many methods returned a "char *" to indicate that the caller owns the memory and must free it. Those are switched to return a std::string instead. Methods that return a "view" into some internal string return a "const char *" instead. I.e., we only copy/allocate when necessary. gdb/ChangeLog: 2016-11-08 Pedro Alves <palves@redhat.com> * ada-lang.c (ada_name_for_lookup, type_as_string): Use and return std::string.

'struct expression *' -> gdb::unique_xmalloc_ptr<expression>
This patch makes parse_expression and friends return a unique_ptr
instead of raw pointer [1]:
typedef gdb::unique_malloc_ptr<expression> expression_up;
and then adjusts the codebase throughout to stop using cleanups to
manage lifetime of expression pointers.
Whenever I found a structure owning an expression pointer, I made it
store a unique_ptr instead of a raw pointer, which then requires using
new/delete of the holding structure, instead of XNEW/xfree.
[1] - I'd like to set the rule that types named with an "_up" suffix
are unique_ptr typedefs.
Note I used gdb::unique_xmalloc_ptr instead of gdb::unique_ptr, simply
because we still use xmalloc instead of new to allocate expression
objects. Once that's changed, all we need to do is change the
expression_up typedef and the smart pointer will then call delete
instead of xfree.

breakpoint.c:commands_command_1 constification and cleanup
This is constification needed for next patch. Adjust commands_command_1 to use std::string too because the "arg" parameter is currently overwritten and then passed to make_cleanup. The constification alone would trigger a compile error in the make_cleanup call otherwise (passing const char * to void * parameter). Using std::string gets rid of the cleanup in the first place, resulting in simpler code. gdb/ChangeLog: 2016-11-08 Pedro Alves <palves@redhat.com> * breakpoint.c (struct commands_info) <arg>: Constify. (commands_command_1): Constify 'arg' parameter. Use std::string and string_printf. (commands_from_control_command): Constify 'arg' parameter. (map_breakpoint_numbers): Constify 'args' parameter. * breakpoint.h (commands_from_control_command): Constify 'arg' parameter. |
