The message below describes the bug  and a fix for a problem building the 
whitepages database on machines running Solaris 2.x.


\bold{\quotation{Excerpts from andrew: 28-Mar-96 Re: need help building wp 
Craig_Everhart@transarc. (1791*)}}

\quotation{***I just found the bug.  In the file

}\quotation{\{ANDREW\}/src/overhead/util/lib/btw.c, function LockFile(), 
the code

}\quotation{tries locking the given file with fcntl() (hiding under

}\quotation{osi_ExclusiveLockNoBlock in that function).  It expects to be 
able to

}\quotation{recognize errors due to a file's not being open in the correct 
mode, and

}\quotation{to recover; but it doesn't recognize what Solaris returns in 
this case,

}\quotation{which is EBADF.  It recognizes EWOULDBLOCK and EINVAL and 
EACCES, but

}\quotation{not EBADF. \


}
Solaris users have to apply this patch to make it work:


diff btw.c_ori btw.c

410c410

<     if (errno != EWOULDBLOCK && errno != EINVAL && errno != EACCES) 
return (bterr_FileSystemErrorBegin + errno);

---

>     if (errno != EWOULDBLOCK && errno != EINVAL && errno != EACCES && 
errno != EBADF) return (bterr_FileSystemErrorBegin + errno);



Tested it on an UFS, not AFS. \
