Subject: [patch] auto-load safe-path default=$ddir/auto-load [Re: [patch] auto-load safe-path reset back by set ""]

This is unrelated to this patch but thanks for the suggestion.

Made it therefore $ddir/auto-load, on an ideal system/distro we can change all
the auto-loaded GDB files to be located under $ddir/auto-load. I have filed
for the only remaining violation (/usr/bin/mono-gdb.py) known to me:
https://bugzilla.redhat.com/show_bug.cgi?id=815501
(Sure I will ask about upstreaming of the change.)

Done. Unfortunately this still does not fix the "./gdb" run for a newly built
GDB. Newly built GDB probably could use "-data-directory $PWD/data-directory"
(if GDB's program dir contains "data-directory" sort of relocation).
We could then change current
gdb-gdb.gdb.in -> gdb-gdb.gdb
to
gdb-gdb.gdb.in -> data-directory/auto-load/$PWD/gdb-gdb.gdb
and even install the file (with proper installation directories) as:
/usr/share/gdb/usr/bin/gdb-gdb.gdb
(additionally ensuring for example in Fedora - in its .spec file
@srcdir@ gets substituted right for Fedora *-debuginfo.rpm)
Would it make everyone happy?
Thanks,

* auto-load.c (auto_load_safe_path_vec_update): Call
substitute_path_component for $ddir.
* configure: Regenerate.
* configure.ac (--with-auto-load-safe-path): Suggest $ddir syntax.
Change the default to \\\$ddir/auto-load.
* defs.h (substitute_path_component): New declaration.

Subject: [patch] auto-load fix multi-dir debug-file-directory
Hi,
I forgot to fix this case myself, Python auto-load was implemented by:
commit 1e5e2afd7cfa6bb62abb9493a514c70489e19c32
Author: Tom Tromey <tromey@redhat.com>
Date: Thu May 28 00:40:23 2009 +0000
while multi-dir debug-file-directory was implemented by
commit 36ae52d16cc9d38cfe317a79bb5d63c624359154
Author: Jan Kratochvil <jan.kratochvil@redhat.com>
Date: Mon Nov 2 14:59:48 2009 +0000
No regressions on {x86_64,x86_64-m32,i686}-fedora17-linux-gnu.
And debug_file_directory really cannot be NULL after GDB initialization code.
Thanks,
Jan

Implement multi-component --with-auto-load-dir.
* NEWS (set auto-load scripts-directory, --with-auto-load-dir): New
entries.
(--with-auto-load-safe-path): Update the default value description.
* auto-load.c (auto_load_dir, set_auto_load_dir, show_auto_load_dir):
New.
(auto_load_objfile_script): Add DEBUG_AUTO_LOAD output. Remove
GDB_DATADIR NULL check. Replace GDB_DATADIR/auto-load by
AUTO_LOAD_DIR. Support $ddir and multiple components in it.
(_initialize_auto_load): Initialize also auto_load_dir. Install new
"set auto-load scripts-directory".
* config.in: Regenerate.
* configure: Regenerate.
* configure.ac (--with-auto-load-dir): New configure option.
(--auto-load-safe-path): Change the default to --with-auto-load-dir.
gdb/doc/
2012-05-09 Jan Kratochvil <jan.kratochvil@redhat.com>
Implement multi-component --with-auto-load-dir.
* gdb.texinfo (Auto-loading): New references
for 'set auto-load scripts-directory'
and 'show auto-load scripts-directory'.
(Auto-loading safe path): Describe the new default. Move $ddir
substituation reference to 'objfile-gdb.py file'.
(objfile-gdb.py file): Describe script-name alias. Change real-name to
script-name. Describe new 'set auto-load scripts-directory'
and 'show auto-load scripts-directory'.
