Invariant failure !driverName.empty() && !driverVersion.empty() ...

[Christopher Baines]

Hey,

I'm having a problem with the mongo command, I've included the details
[1] below. looking at the source code for this I think it's the OS name
that is empty, as it can't open any of the files listed in the source
code [2].

Any ideas on working around this? Also, does anyone know why this
information is being collected, and what is done with it?

Thanks,

Chris

Hi -

Thanks for letting us know that you are experiencing this crash.

That seems plausible. Since you seem comfortable running strace, I think you could confirm your hypothesis by running under GDB and printing the values for the various values. If you confirm that it is in fact he OS value that is missing (or some other one), I'd suggest filing a ticket in the SERVER project describing your findings, since I would consider this a bug.

I think it would also be valuable to include information on what OS you are running.

 

Any ideas on working around this?

Well, you could, temporarily, as a workaround, create one of those files and populate it with something, but I realize that may not be very satisfactory.

 

Also, does anyone know why this
information is being collected, and what is done with it?

This is a new feature in MongoDB 3.4 and associated drivers.

Information about the local system is collected by the shell (and other drivers) and sent to the server on connection establishment. The server logs that information, and also makes some of it programmatically available via the currentOp command, and I think also for slow queries.

As an example, if you look in your database logs, for each connection established to the server you should see lines that look like:

2017-08-24T04:10:59.461+0000 d20761| 2017-08-24T04:10:59.460+0000 I NETWORK  [conn4] received client metadata from www.xxx.yyy.zzz:NNNNN conn: { driver: { name: "Something", version: "x.y.z" }, os: { type: "Linux", name: "Red Hat Enterprise Linux Server release 6.2 (Santiago)", architecture: "x86_64", version: "Kernel 2.6.32-220.el6.x86_64" } }

Documentation is available:

- https://docs.mongodb.com/manual/reference/log-messages/#client-data

- https://docs.mongodb.com/manual/reference/command/currentOp/#iddup.currentOp.appName

You can read the client side specification here:

- https://github.com/mongodb/specifications/blob/master/source/mongodb-handshake/handshake.rst

You may find the motivation section of that specification useful:

- https://github.com/mongodb/specifications/blob/master/source/mongodb-handshake/handshake.rst#motivation-for-change

This information is diagnostic only, and is scoped to your database instance, so you control if/how it is used.

Please let me know if I can provide any more information.

Thanks,

Andrew

Thanks for your prompt response Andrew and all the information you've
provided, I've now got around to looking at this again, and creating a
ticket [1].

https://jira.mongodb.org/browse/SERVER-31105

[Andrew Morrow]

Hi -

Thanks for filing that ticket. We ended up closing is a duplicate, because between when you posted first here and when you filed the ticket, someone else encountered the same issue. I recommend watching https://jira.mongodb.org/browse/SERVER-30857 for a fix (one is already in code review for master, and we will backport this to an upcoming 3.4 release).

Thanks,

Andrew
