Binary connection factory will not recover from a failed connection #189

Open GoogleCodeExporter opened 8 years ago

GoogleCodeExporter commented 8 years ago 
What version of the product are you using? On what operating system?
spymemcached 2.7, jmemcached 1.0.0, Mac OS X

If a memcached crashes, the default (text) connection will recover after 
failing a single operation.  The binary connection will not recover, and will 
continue to throw RuntimeExceptions.

I've attached a test case that runs three different tests, all with 
FailureMode.Retry.  First, it sets a key.  Then it "power cycles" the 
memcached.  Then it attempts to set and get a key.

testCrashedCacheDefaultStrict -- ASCII factory, no failures allowed (fail)
testCrashedCacheDefaultLoose -- ASCII factory, one failure allowed (pass)
testCrashedCacheBinary -- binary factory, one failure allowed (fail)

I would expect all three to pass.  I have explicitly told spymemcached that I 
am okay with retries, and no operations were in flight at the time of the 
"power cycle"

Note that this is likely related to Issue #108 and Issue #181, however I have 
chosen to create a new issue because this one has a self-contained test case 
that only involves one server (rather than an entire cluster, like the other 
issues) and so may be clearer to work in isolation.

Thank you for taking a look at this!

Oops, there is a small typo in that the binary test actually uses 
DefaultConnectionFactory rather than BinaryConnectionFactory.

Thanks for the test!  I hope this has actually already been fixed with recent 
updates, but we'll find out.

This still seems to be a problem :-(

Which version did you re-observe it with @stevenschlansker?

My test still does not pass against master of dustin/java-memcached-client

Hi Steven,

so you are running 2.8.11?
