problems building trunk in OpenBSD/i386

problems building trunk in OpenBSD/i386

[Ryan Yeske]

cvs update -A
./configure
make bootstrap

I get the error:

./temacs --batch --load loadup bootstrap
pid 17656: Fatal error 'Cannot create kernel pipe' at line 200 in file /usr/src/lib/libpthread/uthread/uthread_init.c (errno = 24)
*** Signal 6

EMACS_22_BASE is the last version that I know builds fine on this platform.

Advice on how to proceed in debugging this appreciated.

The backtrace indicates there's infinite recursion in gmalloc.c:

> #365 0x08184f6d in __malloc_initialize () at gmalloc.c:615

These two lines repeat themselves again and again, with calls to other
functions interspersed in between.

I'm guessing that the infinite recursion causes Emacs to eventually
run out of runtime stack, and then it dies with the above weird
message, which really tells you that the program is in deep trouble.

If you can step through the code in question with GDB and try to
understand why it recurses, it will help.

The other parts of the stack trace indicate that the rest of the loop  
is in the C library -- pthread_once calls pthread_mutex_lock, which  
initializes some thread support code, which is causing some priority  
queue code to try to allocate storage, which winds up calling into  
gmalloc, which again ensures that initialization has been done by  
calling pthread_once.

The thread support in gmalloc.c appears to be turned on when gtk is  
available and selected and has the new file chooser interface, and  
pthread support is available.

As to how to fix it... I have no good idea at the moment.  I assume  
OpenBSD uses GCC exclusively; if the platform supports constructor  
attributes on functions, perhaps we could force __malloc_initialize  
to be called at program startup, without thread protection, and hope  
that threads don't get created before main starts.  It seems a bit  
dicey, but hey, so is replacing malloc. :-)  Trying to detect  
recursive calls as opposed to simultaneous calls from multiple  
threads seems tricky, with some of the thread support unavailable  
until after we finish.

It could probably be worked around by specifying a toolkit other than  
gtk, or turning off x11 support altogether, at configure time, until  
we get a real fix.

This sounds like a bug in pthread_once.

I think we safely can call malloc_initialize from main itself without thread 
protection.  The protection is from threads created by the file dialog, and 
they get created when the dialog is first used.  So we should be safe.

Which part?  I think having it allocate storage is perfectly  
acceptable, though if you're explicitly linking against the thread  
library it'd probably be quicker for stuff that'll always be needed  
to be allocated in static storage.  One might argue that internal  
uses of standard C library functions by the system library functions  
should use specially named internal versions of the C library  
functions so as to prevent overriding them, but then you get into  
questions of where you draw the line(s), and what "overriding" is  
really supposed to do.

That sounds like it'll probably work, yes... guess I was looking for  
a too-general solution, suitable for other uses of this gmalloc.c.   
The semantics of some pthread operations and their interactions with  
the language specs are sufficiently vague and subtle[1] that I'd be  
wary of removing any pthread operations, but since malloc_initialize  
and then malloc (with its mutex locking) would be called in the main  
thread before any other threads are created, I think it's probably safe.

I meant the fact that pthread_once tries to initialize stuff twice.  After 
all, it should only do things once.  But I admit that this recursive calling 
of pthread_once is not very well specified as how it should behave.

Maybe all this hooks and stuff can be removed if we switch to SYNC_INPUT.  I 
haven't checked all the details.
