975249ff4e Remove MI version 1
MI version 1 is long since obsolete.  Several years ago, I filed
PR mi/23170 for this.  I think it's finally time to remove this.
Any users of MI 1 can and should upgrade to a newer version.

b8043d2721 Remove a ui-related memory leak
gdb_setup_readline makes new streams and assigns to the various stream
members of struct ui.  However, these assignments cause the previous
values to leak.  As far as I can, this code is simply unnecessary and
can be removed -- with the exception of the assignment to gdb_stdtarg,
which is not initialized anywhere else.

b2a696a881 Use std::string for interpreter_p
The global interpreter_p is a manually-managed 'char *'.  This patch

7ab2607f97 gdbsupport: make gdb_abspath return an std::string
I'm trying to switch these functions to use std::string instead of char
arrays, as much as possible.  Some callers benefit from it (can avoid
doing a copy of the result), while others suffer (have to make one more
copy).

8839e3f3b0 Style URLs in GDB output
I noticed that GDB will display URLs in a few spots.  This changes
them to be styled.  Originally I thought I'd introduce a new "url"
style, but there aren't many places to use this, so I just reused
filename styling instead.  This patch also changes the debuginfod URL
list to be printed one URL per line.  I think this is probably a bit
easier to read.

ebfc93611b Remove unnecessary calls to wrap_here and gdb_flush
Various spots in gdb currently know about the wrap buffer, and so are
careful to call wrap_here to be certain that all output has been
flushed.

Now that the pager is just an ordinary stream, this isn't needed, and
a simple call to gdb_flush is enough.

Similarly, there are places where gdb prints to gdb_stderr, but first
flushes gdb_stdout.  stderr_file already flushes gdb_stdout, so these
aren't needed.

cfeab26e4d Deprecate dbx mode
GDB has a dbx emulation mode that adds a few aliases and helper
commands.  This mode is barely documented and is very superficial
besides.  I suspect it is rarely used, and I would like to propose
deprecating it for GDB 12, and then removing it in GDB 13.

result.  Much of it was written by a script.

e0700ba44c gdb: make string-like set show commands use std::string variable
String-like settings (var_string, var_filename, var_optional_filename,
var_string_noescape) currently take a pointer to a `char *` storage
variable (typically global) that holds the setting's value.  I'd like to
"mordernize" this by changing them to use an std::string for storage.

An obvious reason is that string operations on std::string are often
easier to write than with C strings.  And they avoid having to do any
manual memory management.

Another interesting reason is that, with `char *`, nullptr and an empty
string often both have the same meaning of "no value".  String settings
are initially nullptr (unless initialized otherwise).  But when doing
"set foo" (where `foo` is a string setting), the setting now points to
an empty string.  For example, solib_search_path is nullptr at startup,
but points to an empty string after doing "set solib-search-path".  This
leads to some code that needs to check for both to check for "no value".
Or some code that converts back and forth between NULL and "" when
getting or setting the value.  I find this very error-prone, because it
is very easy to forget one or the other.  With std::string, we at least
know that the variable is not "NULL".  There is only one way of
representing an empty string setting, that is with an empty string.

I was wondering whether the distinction between NULL and "" would be
important for some setting, but it doesn't seem so.  If that ever
happens, it would be more C++-y and self-descriptive to use
optional<string> anyway.

Actually, there's one spot where this distinction mattered, it's in
init_history, for the test gdb.base/gdbinit-history.exp.  init_history
sets the history filename to the default ".gdb_history" if it sees that
the setting was never set - if history_filename is nullptr.  If
history_filename is an empty string, it means the setting was explicitly
cleared, so it leaves it as-is.  With the change to std::string, this
distinction doesn't exist anymore.  This can be fixed by moving the code
that chooses a good default value for history_filename to
_initialize_top.  This is ran before -ex commands are processed, so an
-ex command can then clear that value if needed (what
gdb.base/gdbinit-history.exp tests).

Another small improvement, in my opinion is that we can now easily
give string parameters initial values, by simply initializing the global
variables, instead of xstrdup-ing it in the _initialize function.

In Python and Guile, when registering a string-like parameter, we
allocate (with new) an std::string that is owned by the param_smob (in
Guile) and the parmpy_object (in Python) objects.

This patch started by changing all relevant add_setshow_* commands to
take an `std::string *` instead of a `char **` and fixing everything
that failed to build.  That includes of course all string setting
variable and their uses.

string_option_def now uses an std::string also, because there's a
connection between options and settings (see
add_setshow_cmds_for_options).

The add_path function in source.c is really complex and twisted, I'd
rather not try to change it to work on an std::string right now.
Instead, I added an overload that copies the std:string to a `char *`
and back.  This means more copying, but this is not used in a hot path
at all, so I think it is acceptable.

041ca48e97 gdb: extension languages finish_initialization to initialize
Now that both Python and Guile are fully initialized from their
respective finish_initialization methods, the "finish" in the method
name doesn't really make sense; initialization starts _and_ finishes
with that method.

As such, this commit renames finish_initialization to just initialize.

There should be no user visible changes after this commit.

	'finish_initialization' to 'initialize'.

1178f01adf gdb: initialise extension languages after processing early startup files
Now (thanks to the last few commits) all extension languages are
fully initialised in their finish_initialization method, this commit
delays the call to this method until after the early initialization
files have been processed.

Right now there's no benefit from doing this, but in a later commit I
plan to add new options for Python that will control how Python is
initialized.

With this commit in place, my next commits will allow the user to add
options to their early initialization file and alter how Python starts
up.

	finish_ext_lang_initialization.

92e4e97a9f gdb: process early initialization files and command line options
Adds the ability to process commands at a new phase during GDB's
startup.  This phase is earlier than the current initialisation file
processing, before GDB has produced any output.

The number of commands that can be processed at this early stage will
be limited, and it is expected that the only commands that would be
processed at this stage will relate to some of the fundamentals of how
GDB starts up.

Currently the only commands that it makes sense to add to this early
initialization file are those like 'set style version ....' as the
version string is displayed during startup before the standard
initialization files are parsed.  As such this commit fully resolved
bug cli/25956.

This commit adds a mechanism to execute these early initialization
files from a users HOME directory, as well as some corresponding
command line flags for GDB.

The early initialization files that GDB will currently check for are
~/.config/gdb/gdbearlyinit (on Linux like systems) or ~/.gdbearlyinit
if the former is not found.

The output of 'gdb --help' has been extended to include a list of the
early initialization files being processed.

	PR cli/25956
	* NEWS: Mention new early init files and command line options.

a59902a7c1 gdb: convert auto-load to new-style debug macros
Function file_is_auto_load_safe was taking a format string and varargs
just to output a debug print.  This is probably because that function is
used in linux-thread-db.c and main.c, but debug_auto_load is static in
auto-load.c.  I simplified that, making debug_auto_load visible outside
of auto-load.c, and making the callers of file_is_auto_load_safe output
the debug print themselves.

This file uses _() for internationalization of the debug messages.  This
is not necessary, as these are mostly messages for GDB developers, and
it's not used in other files anyway.  So I removed them.

The rest is pretty much standard.

gdb/ChangeLog:

	* auto-load.h (debug_auto_load): Move here.
	(auto_load_debug_printf): New.
	* auto-load.c: Use auto_load_debug_printf.
	(debug_auto_load): Move to header.
	* linux-thread-db.c (try_thread_db_load): Use
	auto_load_debug_printf.
	* main.c (captured_main_1): Likewise.

21e051b3d6 gdb/main: execute breakpoint commands for '-iex' and '-ex' commands
Suppose we have the script file below:

  break main
  commands
    print 123
  end
  run

If started with this script file, GDB executes the breakpoint command:

  $ gdb -q -x myscript --args ./test
  Reading symbols from ./test...
  Breakpoint 1 at 0x114e: file test.c, line 2.

  Breakpoint 1, main () at test.c:2
  2         return 0;
  $1 = 123
  (gdb)

However, if we remove the "run" line from the script and pass it with
the '-ex' option instead, the command is not executed:

  $ gdb -q -x myscript_no_run --args ./test
  Reading symbols from ./test...
  Breakpoint 1 at 0x114e: file test.c, line 2.
  Starting program: /path/to/test

  Breakpoint 1, main () at test.c:2
  2         return 0;
  (gdb)

If the user enters a command at this point, the breakpoint command
is executed, yielding weird output:

  $ gdb -q -x myscript_no_run --args ./test
  Reading symbols from ./test...
  Breakpoint 1 at 0x114e: file test.c, line 2.
  Starting program: /path/to/test

  Breakpoint 1, main () at test.c:2
  2         return 0;
  (gdb) print "a"
  $1 = "a"
  $2 = 123

When consuming script files, GDB runs bp actions after executing a
command.  See `command_handler` in event-top.c:

  if (c[0] != '#')
    {
      execute_command (command, ui->instream == ui->stdin_stream);

      /* Do any commands attached to breakpoint we stopped at.  */
      bpstat_do_actions ();
    }

However, for '-ex' commands, `bpstat_do_actions` is not invoked.
Hence, the misaligned output explained above occurs.  To fix the
problem, add a call to `bpstat_do_actions` after executing a command.

64aaad6349 gdb: use get_standard_config_dir when looking for .gdbinit
This commit effectively changes the default location of the .gdbinit
file, while maintaining backward compatibility.

For non Apple hosts the .gdbinit file will now be looked for in the
following locations:

  $XDG_CONFIG_HOME/gdb/gdbinit
  $HOME/.config/gdb/gdbinit
  $HOME/.gdbinit

On Apple hosts the search order is instead:

  $HOME/Library/Preferences/gdb/gdbinit
  $HOME/.gdbinit

I've performed an extensive rewrite of the documentation, moving all
information about initialization files and where to find them into a
new @node, text from other areas has been moved into this one
location, and other areas cross-reference to this new @node as much as
possible.

dda83cd783 gdb, gdbserver, gdbsupport: fix leading space vs tabs issues
Many spots incorrectly use only spaces for indentation (for example,
there are a lot of spots in ada-lang.c).  I've always found it awkward
when I needed to edit one of these spots: do I keep the original wrong
indentation, or do I fix it?  What if the lines around it are also
wrong, do I fix them too?  I probably don't want to fix them in the same
patch, to avoid adding noise to my patch.

So I propose to fix as much as possible once and for all (hopefully).

One typical counter argument for this is that it makes code archeology
more difficult, because git-blame will show this commit as the last
change for these lines.  My counter counter argument is: when
git-blaming, you often need to do "blame the file at the parent commit"
anyway, to go past some other refactor that touched the line you are
interested in, but is not the change you are looking for.  So you
already need a somewhat efficient way to do this.

Using some interactive tool, rather than plain git-blame, makes this
trivial.  For example, I use "tig blame <file>", where going back past
the commit that changed the currently selected line is one keystroke.
It looks like Magit in Emacs does it too (though I've never used it).
Web viewers of Github and Gitlab do it too.  My point is that it won't
really make archeology more difficult.

The other typical counter argument is that it will cause conflicts with
existing patches.  That's true... but it's a one time cost, and those
are not conflicts that are difficult to resolve.  I have also tried "git
rebase --ignore-whitespace", it seems to work well.  Although that will
re-introduce the faulty indentation, so one needs to take care of fixing
the indentation in the patch after that (which is easy).

05779d57f9 Make {get,set}_inferior_io_terminal inferior methods
This converts the get_inferior_io_terminal and
set_inferior_io_terminal free functions to inferior methods.

Since the related commands are called "tty", "{set,show}
inferior-tty", and MI's "-inferior-tty-{set,show}", to make the
connection between the commands and the code more obvious, the methods
are named set_tty/tty instead of set_io_terminal/io_terminal.

	* fork-child.c (prefork_hook): Adjust.
	* infcmd.c (set_inferior_io_terminal, get_inferior_io_terminal):

	* inferior.c (inferior::set_tty, inferior::tty): New methods.
	* inferior.h (set_inferior_io_terminal, get_inferior_io_terminal):
	Remove declarations.
	(struct inferior) <set_tty, tty>: New methods.
	(struct inferior) <terminal>: Rename to ...
	(struct inferior) <m_terminal>: ... this and make private.

58cf28e860 Move start_event_loop out of event-loop.c
A subsequent patch is going to move event-loop.c to gdbsupport.  In a
review of an earlier version of this series, Pedro pointed out that
the resulting code would be cleaner if start_event_loop were not
shared -- because gdb and gdbserver have some different needs here --
and so this moves start_event_loop to main.c.  Because the only caller
is there, it is also now static.

d13c7322fe gdb: Allow more control over where to find python libraries
The motivation behind this commit is to make it easier to bundle the
Python *.py library files with GDB when statically linking GDB against
libpython.  The Python files will be manually added into the GDB
installation tree, and GDB should be able to find them at run-time.
The installation tree will look like this:

  .
  |-- bin/
  |-- include/
  |-- lib/
  |   `-- python3.8/
  `-- share/

The benefit here is that the entire installation tree can be bundled
into a single archive and copied to another machine with a different
version of Python installed, and GDB will still work, including its
Python support.

In use the new configure options would be used something like this,
first build and install a static Python library:

  mkdir python
  cd python
  # Clone or download Python into a src/ directory.
  mkdir build
  export PYTHON_INSTALL_PATH=$PWD/install
  cd build
  ../src/configure --disable-shared --prefix=$PYTHON_INSTALL_PATH
  make
  make install

Now build and install GDB:

  mkdir binutils-gdb
  cd binutils-gdb
  # Clone or download GDB into a src/ directory.
  mkdir build
  export GDB_INSTALL_DIR=$PWD/install
  cd build
  ../src/configure \
      --prefix=$GDB_INSTALL_DIR \
      --with-python=$PYTHON_INSTALL_PATH/bin/python3 \
      --with-python-libdir=$GDB_INSTALL_DIR/lib
  make all-gdb
  make install-gdb

Finally, copy the Python libraries into the GDB install:

  cp -r $PYTHON_INSTALL_DIR/lib/python3.8/ $GDB_INSTALL_DIR/lib

After this the Python src, build, and install directories are no
longer needed and can be deleted.

If the new --with-python-libdir option is not used then the existing
behaviour is left unchanged, GDB will look for the Python libraries in
the lib/ directory within the python path.  The concatenation of the
python prefix and the string 'lib/' is now done at configure time,
rather than at run time in GDB as it was previous, however, this was
never something that the user had dynamic control over, so there's no
loss of functionality.

gdb/ChangeLog:

	* config.in: Regenerate.
	* configure: Regenerate.
	* configure.ac: Add --with-python-libdir option.
	* main.c: Use WITH_PYTHON_LIBDIR.

6ec1d75e05 Ensure GDB warnings are styled.
While handling the comments of Tom related to
  [RFC] Have an option to tell GDB to detect and possibly handle mismatched exec-files.
  https://sourceware.org/ml/gdb-patches/2019-12/msg00621.html
I saw that GDB warnings are produced ignoring the given styles.

This patch:
  * ensures that style markups are properly handled by "warning".
  * changes 'set/show data-directory' so that file style is used
    in warnings and in 'show message'
  * changes all other messages in top.c to use file style when appropriate.
  * Uses the above data-directory changes in gdb.base/style.exp

2020-01-03  Philippe Waroquiers  <philippe.waroquiers@skynet.be>

	* ui-file.c (stdio_file::can_emit_style_escape)
	(tee_file::can_emit_style_escape): Ensure style is used also on
	gdb_stderr when gdb_stderr is a tty supporting styling, similarly
	to gdb_stdout.
	* main.c (set_gdb_data_directory): Use file style to output the
	warning that the given pathname is not a directory.
	* top.c (show_history_filename, gdb_safe_append_history)
	(show_gdb_datadir): Use file style.

2020-01-03  Philippe Waroquiers  <philippe.waroquiers@skynet.be>

ed2a222951 Load system gdbinit files from a directory
Adds a configure option --with-system-gdbinit-dir to specify a directory
in which to look for gdbinit files.  All files in this directory are
loaded on startup (subject to -n/-nx as usual) as long as the extension
matches a known and enabled scripting language (.gdb/.py/.scm).

This also changes get_ext_lang_of_file to support ".gdb" files, similar
to get_ext_lang_defn's handling of EXT_LANG_GDB.

cd7c32c36a Fix leak due to assigning a xstrdup-ed string to the std::string gdb_datadir
Valgrind reports the following leak:
==32623== 56 bytes in 1 blocks are definitely lost in loss record 1,099 of 6,654
==32623==    at 0x4835753: malloc (vg_replace_malloc.c:307)

==32623==    by 0x22531A: main (gdb.c:32)

Commit f2aec7f6d1 changed gdb_datadir to std::string.
So, xstrdup-ing the result of relocate_gdb_directory (returning a std::string)
is not needed and creates a leak.

Fix the leak by removing the xstrdup and the not needed c_str ().
Also removes a useless conversion of gdb_datadir to std::string.

ead0e69a4a Change int to bool for the relocate_* functions
These parameters are only used as bools. This also
renames "flag" to "relocatable" to make it clearer
what it does.

b777eb6de2 Remove init_cli_cmds
I noticed that init_cli_cmds only installs a command, and so doesn't
need to be handled specially.  This patch merges it into
_initialize_cli_cmds.

The help text is constructed dynamically, which is sometimes an
indication that special treatment is needed; but in this case it is
just to insert the value of "gdbinit", which is created at
compile-time and not modified; so this doesn't affect the result.

This version also removes the "gdbinit" global.  There's no need for
it, as GDBINIT can be used instead.  Note, though, that the help text
in question must still be dynamically constructed, in order to be
i18n-friendly.
