could identify with certainty to be errors. All of these

o Remove the race between stat(2) & fopen(3) when creating
a unique file.
o Improve bound checking when generating a unique name from
a given pathname.
o Ignore REST marker on APPE. No RFC specifies this case,
but the idea of resuming APPE's implies this.
o By default, deny upload resumes and appends by anonymous users.
Previously these commands were translated to STOU silently,
which led to broken files on server without any notification
to the user.
o Add an option, -m, to allow anonymous users to modify
existing files (e.g., to resume uploads) if filesystem
permissions permit.

objects' reference counts. This function is called by the atexit
mechanism at program shutdown. I don't think the locking is necessary
here. It caused OpenOffice builds to hang more often than not.
Credit to Martin Blapp and Matt Dillon for helping to diagnose this
problem and for testing the fix.
Earlier, a decimal number (e.g., 890) could be passed

accept "void *" in that arguments and have prototypes. Thus, the
casts are useless under the normal circumstances (and would be harmful
if the functions had no prototypes.)

Thus lines of any length can be handled, unlike before.
Don't assume that each line read from the files ends with a newline.
As a side effect in inithosts(), don't use automatic buffer at all,
utilize malloc(3) when getting local host name instead.

They provided little benefit (if any) and they caused some problems
in OpenOffice, at least in post-KSE -current and perhaps in other
environments too. The nanosleep calls prevented the profiling timer
from advancing during the spinloops, thereby preventing the thread
scheduler from ever pre-empting the spinning thread. Alexander
Kabaev diagnosed this problem, Martin Blapp helped with testing,
and Matt Dillon provided some helpful suggestions.
This is a short-term fix for a larger problem. The use of spinlocking
isn't guaranteed to work in all cases. For example, if the spinning
thread has higher priority than all other threads, it may never be
pre-empted, and the thread holding the lock may never progress far
enough to release the lock. On the other hand, spinlocking is the
only locking that can work with an arbitrary unknown threads package.
I have some ideas for a much better fix in the longer term. It
would eliminate all locking inside the dynamic linker by making it
safe for symbol lookups and lazy binding to proceed in parallel
with a call to dlopen or dlclose. This means that the only mutual
exclusion needed would be to prevent multiple simultaneous calls
to dlopen and/or dlclose. That mutual exclusion could be put into
the native pthreads library. Applications using foreign threads
packages would have to make their own arrangements to ensure that
they did not have multiple threads in dlopen and/or dlclose -- a
reasonable requirement in my opinion.

so that the process can use it to behave differently depending on the
origin on the request. We use this to implement rudimentary visibility
control on our user information.
Make sure that the child process's standard error goes through the same
NVT-ASCII filter as is applied to the standard output.
Don't attempt to call logerr() from the child since stdio is not safe in
a vforked process. Just write a message to fd 2 instead. (Ideally, the
parent would open two pipes, and siphon off our stderr to some place less
public, but I have not attempted to do so in this implementation.)

Thanks to Bruce Evans for identifying the cause of the build

Untested (testing request went unanswered), but sparc64 is not expected to
cause problems. IA64 is not expected to cause problems but the patch was
slightly more complex so the possibility exists.
