| Description: |
Tcl can crash during shutdown in multithreaded applications on systems
using pthreads. This applies to e.g. Linux or Mac OS X when compiled without
-DPUFIY. In Tcl (e.g. core-8-6-branch, AFIKT since "ever") the function
TclpFreeAllocCache() is called twice during thread shutdowns, once via
"manual" call indirectly via Tcl_FinalizeThread(), and once via pthreads.
The automatic call happens, since Tcl registers TclpFreeAllocCache() with
pthread_key_create(&key, TclpFreeAllocCache);
The duplicated call itself is usually not harmful (but useless), but poses a
serious problem when a multi-threaded C program registers a thread-shutdown
callback via
pthread_key_create(&key, CleanupFunction);
where typically CleanupFunction() calls some Tcl-script and then
Tcl_FinalizeThread(). In such cases, the order of calls of
TclpFreeAllocCache() and CleanupFunction() is random, since
http://pubs.opengroup.org/onlinepubs/009695399/functions/pthread_key_create.html
states that the order of destructor calls is unspecified, when more
than one destructor exists for a thread when it exits. After a call to
TclpFreeAllocCache() no Tcl eval can be performed in this
thread. Attempts are likely to crash. The problem is quite old but has
intensified in tcl 8.6 due to the NRE machinery (TclNRAddCallback(),
TclNREvalObjv()) which puts more stress on memory management.
I would argue, that every larger threaded C program has to register a
per-thread exit handler for per-thread cleanups. This happens as well
in NaviSever/AOLserver, where tcl-based callbacks can be registered
for interp destroys.
One simple fix is to prevent the double invocation of
TclpFreeAllocCache() and to rely on the manual call in
Tcl_FinalizeThread(). This is actually nothing new and corresponds to
current behavior under windows (there is not "automatic" call either).
Note that the problem does not exist on unix systems when compiled
with -DPURIFY, since in such cases, TclpFreeAllocCache() is never
called.

Note, that the source code documentation was not correctly describing
the current behavior either. The attached patch suggests some
improvements.
See below for evidence of crashes and the sketched behavior. The first
listings shows printf-traces with thread-IDs, where the intersting
lines of the thread with ID 7000003a6000 are marked with "A". It shows
a case, where TclpFreeAllocCache() is called automatically via
pthreads, before the thread exit handler NaviServer could call
Tcl_FinalizeThread().
The second listing shows a backtrace of such a crash. Since
TclpFreeAllocCache() was called before, tcl crashes in TclNREvalObjv(),
or more precisely in
TclNRAddCallback(interp, NRCommand, NULL, NULL, NULL, NULL);
where it attempts to obtain memory. This crash happens before Tcl_FinalizeThread(). The patch will not cause any difference on systems
where Tcl_FinalizeThread() is called.
All said applies to Tcl 8.5 as well.

===================================================
In order to reproduce this crashes, get e.g. the actual version of NaviServer
from bitbucket [1], compile it, and run
make test TESTFLAGS="-file ns_parseurl.test"
a few times from its install directory. The crash happens even more often,
when the final cleanup call is not omitted [2].

Fix committed to core-8-5-branch, core-8-6-branch and trunk. Thanks, Gustaf! gustafn2 added on 2016-10-07 13:14:55: found a second documentation flaw related to the allocator cache, and added an additional patch file. gustafn2 added on 2016-09-26 18:24:48: here is the patch... jan.nijtmans added on 2016-09-26 14:47:48: > Note, that the source code documentation was not correctly describing > the current behavior either. The attached patch suggests some > improvements. Where can I find this documentation patch? Indeed, I think the best thing to do is rely on the TclpFreeAllocCache() call in Tcl_FinalizeThread(). So I agree with your patch, and welcome your suggestions for documentation improvement. | |||
