bug#1079: GNUstep port segfaults making autoloads on x86_64

[Glenn Morris]

Trying to bootstrap the GNUStep port on x86_64 GNU/Linux, it segfaults
making autoloads. The problem can be reduced to anything that tries to
set a variable, eg:

../src/bootstrap-emacs -batch --no-site-file \
  --eval '(setq make-backup-files nil)' 

Disclaimer: I know nothing about GNUStep, I just grabbed a tarball and
made a local installation of it.

Hmm, not sure if this ns_init_paths() is needed during the bootstrap  
-- i.e., should the conditional be different, or should it be moved  
after the init_...() calls?  Unf I cannot test this stuff myself.

I tried commenting it out; then I get a segfault loading
term/ns-win.el from the ns-list-colors call.

I tried (randomly) moving it after init_cmdargs; didn't make a
difference.

Since it works (for this stage at least) on 32-bit, but not 64, I
don't think something like that can be the answer.

It's the very first line of ns_init_paths that is the problem, does
this suggest anything?

NSBundle *bundle = [NSBundle mainBundle];

It's just an ordinary API call, but it's not meant to be run from an  
app that is not inside a "bundle".  That is, once packaged into  
Emacs.app directory structure, it's OK to run this call, but the  
behavior would be undefined if just being run as src/[t]emacs.  From  
your stack trace it looked like GNUstep tried to initialize some of  
its internals and ran into an unexpected condition causing the crash.

So, if there were some way to run ns_init_paths() only in either  
dumped emacs, or CANNOT_DUMP emacs but NOT during bootstrapping, I  
think that would be best.

(I may not have fully thought this through when I first wrote that  
conditional, probably since the ns_init_paths impl originally didn't  
call -mainBundle.)

As for the location before or after init_ calls, on second thought I'm  
not sure this matters a lot.  I believe I put it the same place the  
Carbon port had its equivalent call.

Regarding the later segfault after commenting out, ns_init_paths only  
sets environment variables affecting emacs lisp load paths, does not  
initialize anything else.  So I'd say this is a separate bug.

Which version of GNUstep Base is this?

Can you run the testsuite on that machine, e.g.

svn co http://svn.gna.org/svn/gnustep/tests/testsuite/trunk gnustep-testsuite
cd gnustep-testsuite
make

and post the output of the failed tests and the summary?

If the -mainBundle method call fails because the app is not yet
installed, it should fail on other architectures too.  Perhaps there's
something else here.

I was going to ask if my GNUstep installation could be messed up somehow...

Disclosure: my GNUstep.conf file is not in /etc, so I patched
configure to accept a path to GNUstep.conf. I haven't submitted that
yet since I don't know if am doing the right thing. But I don't see
that it would make a difference to this.

Emacs's configure, in case that was unclear, ie will not affect these tests.

You also wanted the tests.log output. Here are the failed pieces from
x86_64:

That should contain the latest stable releases, so it must be OK (I've
never installed this way, though.)

This is a bit worrisome.  Just to rule out the possibility, can you
compile gnustep-base against libffi in case it was built with
libffcall (and vice-versa -- rebuild it with libffcall if it was with
libffi).  There were numerous problems with both, and libffi became
preferred by upstream a few months ago.

Oh, of course not; this file is not being read at all at this point.
Nevertheless, still fixes a harmless runtime warning.

Thanks.  I can't see how this can be a bug in Emacs.  The arguments of
bootstrap-emacs are evaluated as property lists and since "(setq foo
1)" (or whatever is passed to --batch in such form) is not a validly
formatted array, an NSException is raised here:

#5  0x00002b51204f9fbb in GSPropertyListFromStringsFormat (string=0x1b392730)
    at NSPropertyList.m:1505
        dict = (class NSMutableDictionary *) 0x0
        _pld = {
  ptr = 0x1b281c70 "(setq foo 1)", 
  end = 12, 
  pos = 0, 
  lin = 0, 
  err = 0x2b512095f000, 
  opt = NSPropertyListImmutable, 
  key = 0 '\000', 
  old = 1 '\001'
}

However, this exception should be caught and handled by the parent
exception handler at NSUserDefaults.m:1814 -- note the comment there:

          else

This is precisely the case here, and it's handled properly on i386.

It is getting too complicated for me, but can you compile this test
program (it should never crash):

test.m:
=======
#import	<Foundation/Foundation.h>

int
main (int argc, char** argv, char **env)
{
  NSAutoreleasePool *pool = [NSAutoreleasePool new];
  NSProcessInfo	    *proc = [NSProcessInfo processInfo];
  NSBundle        *bundle = [NSBundle mainBundle];
  NSArray	    *args;
  unsigned		i;
  int              retval = 0;

  [NSProcessInfo initializeWithArguments:argv
		 count:argc
		 environment:env];

  args = [proc arguments];
  GSPrintf (stderr, @"Useless info about bundle: %@\n", bundle);

  if ([args count] <= 1)
    {
      GSPrintf (stderr, @"Please specify some arguments.\n");
      RELEASE (pool);
      exit (EXIT_FAILURE);
    }
  else if ([[proc environment] valueForKey:@"NOHANDLE"] != nil)
    GSPrintf (stderr, @"NOHANDLE defined; should exit with success.\n");
  else
    {
      for (i = 1; i < [args count]; i++)
	{
	  NSString	*opt = [args objectAtIndex: i];

 	  NS_DURING
	    {
	      NSString	*tempString;
	      id	result;

	      tempString = [NSString stringWithString: opt];
	      if (tempString == nil)
		GSPrintf (stderr, @"This should not happen.\n");
	      /* Exception handler taking care here.  */
	      else if (![tempString propertyList]); 
	      else if ((result = [tempString propertyList]) == nil)
	       	GSPrintf (stderr, @"'%@' - a nil property list.\n", opt);
	      else if ([result isKindOfClass: [NSDictionary class]] == YES)
		GSPrintf (stderr, @"'%@' - a dictionary.\n", opt);
	      else if ([result isKindOfClass: [NSArray class]] == YES)
		GSPrintf (stderr, @"'%@' - an array.\n", opt);
	      else if ([result isKindOfClass: [NSString class]] == YES)
		GSPrintf (stderr, @"'%@' - a string.\n", opt);
	      else
		GSPrintf (stderr, @"'%@' - unknown class %@.\n",
		  opt, [[result class] description]);
	    }
	  NS_HANDLER
	    {
	      GSPrintf (stderr, @"'%@' failed with:\n%@.\n", opt,
		[localException reason]);
	      GSPrintf (stderr, @"Failure.\n");
	      retval = 1;
	    }
	  NS_ENDHANDLER
	}
    }
  RELEASE (pool);
  return retval;
}

You can use this simple makefile to build it:

GNUmakefile:
============
include $(GNUSTEP_MAKEFILES)/common.make
TOOL_NAME = test
test_OBJC_FILES = test.m
include $(GNUSTEP_MAKEFILES)/tool.make

Just type `make'.

Then test it as follows (the executable should be /obj/test):

(gdb) r '{a=b; c=d}' '(foo, bar)' --batch '(setq foo 1)'
...
(gdb) set environment NOHANDLE=yes
(gdb) r	  (with the same arguments)

Thanks.

I don't have either. gnustep-startup provides both, but uses ffcall by
default. I tried to get it to use ffi instead, but it did not work out
of the box and I haven't had time to look into it yet.

Installed.

bug#1079: GNUstep port segfaults making autoloads on x86_64

AFAICS ./InstallGNUstep --ffi=libffi should DTRT.
Failing that, ./configure --enable-libffi --disable-ffcall in the
gnustep-base tree should suffice (after installing libffi).  It is
enough to recompile only GNUstep Base, not the whole thing.

Maybe someone else with access on a x86_64 machine can try this.

It is excellent that it crashes, this confirms it's a GNUstep bug.  It
looks like it is unable to pass the exception up to the call stack or
something like that.

Before reporting it to the GNUstep developers, it would be useful to:

1) Check if it still crashes with -base built against libffi.
2) Check if the problem persists in SVN trunk:
   svn co http://svn.gna.org/svn/gnustep/libs/base/trunk gnustep-base

bug#1079: GNUstep port segfaults making autoloads on x86_64

reassign 1079 gnustep
stop

It doesn't work, it builds libffcall anyway.

Reassigned as such.

Still crashes with trunk gnustep-base built against libffi.

Maybe that's the culprit; -[NSString propertyList] is called,
resulting in NSException, because the .plist file is not a valid
dictionary (at least according to the plparse tool).

Does the naive patch below eliminate this problem?

	* GNUstep/Emacs.base/Resources/Info-gnustep.plist: Add missing
