Hi @jameinel Thanks for taking the time to open a PR - this is definitely important. Do you have a test case we can use to reproduce? I suppose run a txn and kill half way through? Dom |

This was a patch we put together quite a while ago, and have been running.
I've been trying to clear out our backlog of patches.
I will see if I can get anyone who has/had more context to think about
doing a patch. I do think it is a case of needing to have a disconnect
trigger at exactly the right time. Maybe we could do something with the
Chaos code. Use the 'set-applying' chaos point to create a disconnect to
Mongo and then see that you get an error bubbling up instead of cycling and
endless looping.

(the other one I'm looking to bring in is go-mgo#303, I'll look to get that polished as well.) |

That would be great, thanks very much! Could you retarget this to development and I'll get it merged and tested manually for now. Thanks again! |

Changed the target to develop, and rebased to just the simple patch. |
|
Should development merge in all of master? there seems to be a few missing revisions |

Thanks for taking the time to upstream your changes @jameinel - it's really appreciated. There's something odd going on with the github diff - if you check the I'll look forward to your other PRs! Dom |

* 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. * Respect nil slices, maps in bson encoder (globalsign#147) * socket: only send client metadata once per socket (globalsign#105) Periodic cluster synchronisation calls isMaster() which currently resends the "client" metadata every call - the spec specifies: isMaster commands issued after the initial connection handshake MUST NOT contain handshake arguments https://github.com/mongodb/specifications/blob/master/source/mongodb-handshake/handshake.rst#connection-handshake This hotfix prevents subsequent isMaster calls from sending the client metadata again - fixes globalsign#101 and fixes globalsign#103.

This brings forward a patch that we created for mgo a while ago.
It is possible that if the connection dies in the middle of flushing a transaction, you can get into an endless loop. This causes it to fail with an error instead.
Original PR was here: go-mgo#360
