Somewhat resolved -- Re: [Vm-dev] when the vm crashes...

I've come to understand a bit about why the VM was crashing when making requests via SqueakSSL. For some sites I could make request after request with no ill effects. A successful request/response looks like this:

Mar 30 14:05:47 *user*: sqEncryptSSL: Encrypting 91 bytes Mar 30 14:05:47 *user*: SqueakSSLWrite: Writing 117 bytes, having 191 free === the encrypted request to be sent Mar 30 14:05:47 *user*: sqDecryptSSL: Input data 2896 bytes Mar 30 14:05:47 *user*: sqDecryptSSL: Decrypting 2896 bytes Mar 30 14:05:47 *user*: SqueakSSLRead: Requesting 5 bytes, having 2896 bytes Mar 30 14:05:47 *user*: SqueakSSLRead: Requesting 13168 bytes, having 2891 bytes Mar 30 14:05:47 *user*: sqDecryptSSL: Input data 2896 bytes Mar 30 14:05:47 *user*: sqDecryptSSL: Decrypting 2896 bytes Mar 30 14:05:47 *user*: SqueakSSLRead: Requesting 10277 bytes, having 2896 bytes Mar 30 14:05:47 *user*: sqDecryptSSL: Input data 1448 bytes Mar 30 14:05:47 *user*: sqDecryptSSL: Decrypting 1448 bytes Mar 30 14:05:47 *user*: SqueakSSLRead: Requesting 7381 bytes, having 1448 bytes Mar 30 14:05:47 *user*: sqDecryptSSL: Input data 4096 bytes Mar 30 14:05:47 *user*: sqDecryptSSL: Decrypting 4096 bytes Mar 30 14:05:47 *user*: SqueakSSLRead: Requesting 5933 bytes, having 4096 bytes Mar 30 14:05:47 *user*: sqDecryptSSL: Input data 3144 bytes Mar 30 14:05:47 *user*: sqDecryptSSL: Decrypting 3144 bytes Mar 30 14:05:47 *user*: SqueakSSLRead: Requesting 1837 bytes, having 3144 bytes Mar 30 14:05:47 *user*: sqDecryptSSL: Input data 0 bytes Mar 30 14:05:47 *user*: sqDecryptSSL: Decrypting 1307 bytes Mar 30 14:05:47 *user*: sqDecryptSSL: Input data 0 bytes Mar 30 14:05:47 *user*: sqDecryptSSL: Decrypting 1307 bytes Mar 30 14:05:47 *user*: sqDecryptSSL: Input data 0 bytes Mar 30 14:05:47 *user*: sqDecryptSSL: Decrypting 1307 bytes Mar 30 14:05:47 *user*: SqueakSSLRead: Requesting 5 bytes, having 1307 bytes Mar 30 14:05:47 *user*: SqueakSSLRead: Requesting 7488 bytes, having 1302 bytes Mar 30 14:05:47 *user*: sqDecryptSSL: Input data 0 bytes Mar 30 14:05:47 *user*: sqDecryptSSL: Decrypting 0 bytes Mar 30 14:05:47 *user*: SqueakSSLRead: Requesting 6186 bytes, having 0 bytes Mar 30 14:05:47 *user*: sqDecryptSSL: Input data 2896 bytes Mar 30 14:05:47 *user*: sqDecryptSSL: Decrypting 2896 bytes Mar 30 14:05:47 *user*: SqueakSSLRead: Requesting 6186 bytes, having 2896 bytes Mar 30 14:05:47 *user*: sqDecryptSSL: Input data 3290 bytes Mar 30 14:05:47 *user*: sqDecryptSSL: Decrypting 3290 bytes Mar 30 14:05:47 *user*: SqueakSSLRead: Requesting 3290 bytes, having 3290 bytes Mar 30 14:05:47 *user*: sqDecryptSSL: Input data 0 bytes Mar 30 14:05:47 *user*: sqDecryptSSL: Decrypting 0 bytes Mar 30 14:05:47 *user*: SqueakSSLRead: Requesting 5 bytes, having 0 bytes Mar 30 14:05:47 *user*: sqDecryptSSL: Input data 0 bytes Mar 30 14:05:47 *user*: sqDecryptSSL: Decrypting 0 bytes Mar 30 14:05:47 *user*: SqueakSSLRead: Requesting 5 bytes, having 0 bytes and this can repeat many times as request after request succeeds.

Other sites would crash the vm after a small number of requests. With the insertion of enough "String new" calls in the right place, the crash could almost be guaranteed to occur on the first attempt. A failure looks like this:

22 bytes, having 22 bytes

data all received now, but what's this:

Mar 30 13:54:36 *user* SqueakSSLWrite: Writing 27 bytes, having 75 free Mar 30 13:54:36 *user* sqDecryptSSL: SSLRead returned -9805 Mar 30 13:54:36 *user* last object overwritten

errSSLClosedGraceful -9805 The connection closed gracefully. Available in OS X v10.2 and later.

this is the only SqueakSSLWrite: not immediately following a sqEncryptSSL, so where did it come from? I don't know, but I do know it's using the same buffer provided in the last sqEncryptSSL call. The problem is that this buffer was a method temp and may well have moved or been gc'd in the interim. My hack was to make the buffer used by encrypt and connect a permanent one to minimize the chance of movement. Just to verify, I zeroed this buffer once the request had been sent and checked it after the response had been received. This is what it looked like:

#[0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 21 3 1 0 22 183 80 173 250 155 255 108 25 132 220 40 109 216 134 178 73 243 155 35 75 231 89 0 0 0...

the 27 bytes indicated in the squeakssl log output were inserted in this buffer at the next output position. Not sure why this extra write happens where it does or if it happens in other OS configurations, so the real fix is still a mystery. I think I can live with the global buffer for my purposes.

Eliot,

I figured out where the "console" ends up and you are right - is
was last object overwritten. File attached if it's of any use. My
testing has proceeded to the point that repeated calls to
"SqueakSSL google: 'squeak'" work fine, but calls to a very
similar method connecting to a different host will crash the vm
after a few iterations.

At this point I would switch to gdb, set a breakpoint in error, run the reproducible case, then use

call printOop(objectBefore(freeStart))

to find out which object was overwritten. That may be a good enough clue to find out where the overwriting is occurring. You can try

call longPrintOop(objectBefore(freeStart))

which may give you more info.

Cheers,
Bob

    Is there enough information in the attached file to point to

Yes.  But there should hopefully be the output of error on the
console and that would disambiguate between the two possible
causes.  This is the stack:

2   libsystem_c.dylib 0x9b609bdd abort + 167
3   org.squeak.SqueakAllInOne45 0x000703be error + 94
4   org.squeak.SqueakAllInOne45 0x000d1c4f
eeInstantiateSmallClasssizeInBytes + 95
5   org.squeak.SqueakAllInOne45 0x000d31a0
createClosureNumArgsnumCopiedstartpc + 80
6   org.squeak.SqueakAllInOne45 0x000c6e69
ceClosureCopyDescriptor + 41
There are two possible errors in eeInstantiateSmallClasssizeInBytes
error("last object overwritten");
error("out of memory");


The first means that something wrote past the end of an object
and this was detected when a new object was allocated, seeing
that freeSpace did not contain the pattern expected.  This e.g.
happens when passing buffer objects to foreign code which writes
beyond the object.

The second usually means infinite recursion.  Looking at the
memory map at the end of the error report I think that the error
is last object overwritten.


    Cheers,
    Bob
