Re: [VOTE] Release Apache Tomcat 6.0.52

Rainer Jung Thu, 30 Mar 2017 14:56:12 -0700

Using gdb I see:

Case 1:

#7 impl_pollset_remove (pollset=0xeebf68, descriptor=0xb377f6a4) atpoll/unix/port.c:283

        fd = <optimized out>
        ep = <optimized out>
        rv = 0
        res = <optimized out>
        err = 0
        found = <optimized out>

#8 0xfaddfcdc in apr_pollset_remove (pollset=0xeebf68,descriptor=descriptor@entry=0xb377f6a4) at poll/unix/pollset.c:343

No locals.

#9 0xfaed4b88 in Java_org_apache_tomcat_jni_Poll_maintain (e=0x659884,o=<optimized out>, pollset=<optimized out>, set=0xb377f82c,remove=<optimized out>) at src/poll.c:484fd = {p = 0x0, desc_type = APR_POLL_SOCKET, reqevents = 5,rtnevents = 0, desc = {f = 0x0, s = 0x0}, client_data = 0xe527b8}

        s = <optimized out>
        p = 0x1157648
        i = 0
        num = 1
        now = <optimized out>
        ep = <optimized out>
        ip = <optimized out>

(gdb) print *pollset

$1 = {pool = 0xeebf28, nelts = 0, nalloc = 8193, flags = 6, wakeup_pipe= {0x1157558, 0x11575a8}, wakeup_pfd = {p = 0xeebf28, desc_type =APR_POLL_FILE, reqevents = 1,rtnevents = -16516, desc = {f = 0x1157558, s = 0x1157558},client_data = 0xeebf7c}, p = 0xeebfa0, provider = 0xfadf8838}

(gdb) print *descriptor

$2 = {p = 0x0, desc_type = APR_POLL_SOCKET, reqevents = 5, rtnevents =0, desc = {f = 0x0, s = 0x0}, client_data = 0xe527b8}

(gdb) print *pollset->pool

$3 = {parent = 0x6557d0, child = 0x0, sibling = 0x0, ref = 0x13b8c60,cleanups = 0x1157638, free_cleanups = 0x0, allocator = 0x319d68,subprocesses = 0x0, abort_fn = 0,user_data = 0x0, tag = 0x0, active = 0xde0a50, self = 0xeebf10,self_first_avail = 0xeebf68 "", pre_cleanups = 0x0}



So we crash here:

282     if (descriptor->desc_type == APR_POLL_SOCKET) {
=> 283         fd = descriptor->desc.s->socketdes;
284     }
...

because descriptor->desc.s is NULL.


Case 2:

#8 0xfadd8980 in allocator_free (node=0xb8f170, allocator=0x2d8238) atmemory/unix/apr_pools.c:370

        freelist = 0x0
        max_index = <optimized out>
        max_free_index = <optimized out>
        next = <optimized out>
        index = <optimized out>
        current_free_index = <optimized out>
#9  apr_pool_destroy (pool=0xb8f188) at memory/unix/apr_pools.c:856
        active = 0xb8f170
        allocator = 0x2d8238

(gdb) print *node

$2 = {next = 0x0, ref = 0xb8f170, index = 0, free_index = 1465,first_avail = 0x0, endp = 0xb91170 ""}

(gdb) print *allocator

$1 = {max_index = 7756680, max_free_index = 1601139303,current_free_index = 0, mutex = 0x6368655f, owner = 0x0, free ={0x61745f6a, 0x0, 0x72726f72, 0x5f737472, 0x6572726f,0x7200ffff, 0x4, 0x7a8, 0xffffffff, 0x0, 0x6, 0xb91b20, 0x7,0x765b88, 0xffffffff, 0x0, 0x9, 0xffffffff, 0xffffffff, 0xa}}

(gdb) print *allocator->mutex
Cannot access memory at address 0x6368655f


So we crash here:

 369     if (allocator->mutex)
=>  370         apr_thread_mutex_lock(allocator->mutex);

since the mutex is already invalid.


Case 3:

#8 0xfadd8980 in allocator_free (node=0x5bd138, allocator=0xd7f138) atmemory/unix/apr_pools.c:370

        freelist = 0x0
        max_index = <optimized out>
        max_free_index = <optimized out>
        next = <optimized out>
        index = <optimized out>
        current_free_index = <optimized out>
#9  apr_pool_destroy (pool=0x5bd150) at memory/unix/apr_pools.c:856
        active = 0x5bd138
        allocator = 0xd7f138

(gdb) print *node

$1 = {next = 0x6d1bd8, ref = 0x5bd138, index = 0, free_index = 65,first_avail = 0xf24cf8 "", endp = 0x5bf138 ""}

(gdb) print *allocator

$2 = {max_index = 16381824, max_free_index = 1601139303,current_free_index = 6773064, mutex = 0x6368655f, owner = 0x87cf60, free= {0x61745f6a, 0x0, 0x72726f72, 0x5f737472,0x6572726f, 0x72000c0c, 0xc0c0c01, 0x30, 0x1010100, 0x0, 0x0,0x675948, 0x59b70002, 0x706e10, 0x1204b600, 0x0, 0x5b60006, 0xb700072a,0x1bb50008, 0xd7f130}}

(gdb) print *allocator->mutex
Cannot access memory at address 0x6368655f


So the same as Case 2.


Case 4:

Not easily analyzable with gdb.

Rainer

The proposed Apache Tomcat 6.0.52 release is now available for voting.

Note: This is the last Tomcat 6 release.

It can be obtained from:
https://dist.apache.org/repos/dist/dev/tomcat/tomcat-6/v6.0.52/
The Maven staging repo is:

The svn tag is:

The proposed 6.0.52 release is:
[ ] Broken - do not release
[ ] Stable - go ahead and release as 6.0.52 Stable


I see JVM crashes in APR:

org.apache.catalina.connector.TestSendFile
 testSendFile
org.apache.catalina.core.TestApplicationContext
 testGetRequestDispatcherNullPath02
org.apache.catalina.core.TestApplicationHttpRequest testMergeQueryString02
org.apache.catalina.startup.TestTomcat testSingleWebapp

all result in:

does not reflect the time until the VM exit.
junit.framework.AssertionFailedError: Forked Java VM exited abnormally.
Please note the time in the report does not reflect the time until the
VM exit.

I'd say they happen during shutdown.

Here are the stacks of the crashing threads:
