Cluster abended test 254 #100

This adds an explicit test for the Abended behavior that was added in issue #255. I'm not entirely sure what Copyright to assign, and I feel a little bad about peeking under the covers, but it wasn't clear if there was another way to actually test the behavior.

I was able to reproduce this manually using "tcpkill".
I essentially had live connections to mongo, and used "lsof -i 27017" to find what sockets were connected to mongo. I then ran "tcpkill -i lo 'port 54321'" (you can use the mongo port, but it causes all connections to die, rather than just targeting a single one.)

By killing a single connection, the client side flags the server as "abended" and triggers the bad behavior.

Hi @jameinel

I'm going to sort out the development/master branch diff - it's getting confusing! I'll get back to you regarding this PR (the conflict might not be an issue).

Thanks!

Hi John,

Yes please, that would be great! I think there's something weird going on with this diff though - I've already added a fix for this:

mgo/cluster.go

Line 664 in 896bbb8

server.abended = false

I'll still happily take the test that goes with it though!

Rebased. I had to replay your patch on the branch I had started on, and I added a comment to justify why it was ok to do.

Hey @jameinel

There's a rouge import for the old mgo in server_test.go that's causing tests to fail - can you swap it for this repo and we'll get this merged?

Thanks!

This brings in a test which fails without the patch, and passes with the
patch. Still to be tested, manual tcpkill of a socket.

It looks like you changed 'development' so I rebased again rather than bring in all the other 'master' patches.

* fix(dbtest): Use os.Kill on windows instead of Interrupt 🐛

I've added a use for os.Kill, instead of os.Interrupt signal, when using
Windows. I'm current developing my project on Windows, and using
DBServer.Stop() was resulting in: "timeout waiting for mongod process to
die". After investigating, I've discovered that os.Interrupt isn't
implemented on Windows, and it seems golang has Frozen this issue due to
age (2013). They instruct to use os.Kill instead. Using this, the
DBServer on my project works with no problem.

* socket: only send client metadata once per socket

Periodic cluster synchronisation calls isMaster() which currently resends the

This hotfix prevents subsequent isMaster calls from sending the client metadata

* Release/r2018.06.15 (#191)

* allow ptr in inline structs

* inline pointer_to_struce mode: update comments. return error on pointer not to struct

* fix(dbtest): Use os.Kill on windows instead of Interrupt 🐛

I've added a use for os.Kill, instead of os.Interrupt signal, when using
Windows. I'm current developing my project on Windows, and using
DBServer.Stop() was resulting in: "timeout waiting for mongod process to
die". After investigating, I've discovered that os.Interrupt isn't
implemented on Windows, and it seems golang has Frozen this issue due to
age (2013). They instruct to use os.Kill instead. Using this, the
DBServer on my project works with no problem.

* readme: credit @dvic and @KJTsanaktsidis

* added support for marshalling/unmarshalling maps with non-string keys

* refactor method receiver

* added support for json-compatible support for slices and maps Marshal() func: nil slice or map converts to nil, not empty (initialized with len=0)

* fix IsNil on slices and maps

* Separate read/write network timeouts (#161)

* socket: separate read/write network timeouts

Splits DialInfo.Timeout (defaults to 60s when using mgo.Dial()) into ReadTimeout
and WriteTimeout to address #160. Read/write timeout defaults to
DialInfo.Timeout to preserve existing behaviour.

* cluster: remove AcquireSocket

Only used by tests, replaced by the pool-aware acquire socket functions:
	* AcquireSocketWithPoolTimeout
	* AcquireSocketWithBlocking

* cluster: use configured timeouts for cluster operations

* `mongoCluster.syncServer()` no longer uses hard-coded 5 seconds
* `mongoCluster.isMaster()` no longer uses hard-coded 10 seconds

* tests: use DialInfo for internal timeouts

* server: fix fantastic serverTags nil slice bug

When unmarshalling serverTags, it is now an empty slice, instead of a nil slice.

`len(thing) == 0` works all the time, regardless.

* cluster: remove unused duplicate pool config

* session: avoid calculating default values in hot path

Changes `DialWithInfo` to handle setting default values by setting the relevant
`DialInfo` field, rather than calling the respective methods in the hot path for:

	* `PoolLimit`
	* `ReadTimeout`
	* `WriteTimeout`

* session: remove unused consts

* session: update docs

* add URI options: "w", "j", "wtimeoutMS" (#162)

* add URI options: "w", "j", "wtimeoutMS"

* change "w" to "j"

The documentation now explains the difference between calling Err and
Close after Next returns false.

The example code has been expanded to include checking for timeout.

* add NewMongoTimestamp() and MongoTimestamp.Time(),Counter() (#171)
