The Trouble Ticket

When I first started a job at a recent employer, I was quickly assigned The Ticket. This ticket had been in the system since time immemorial, and had been passed around all of the administrators in the team. The comment history scrolled for pages and pages.

On the surface, it didn't really look all that bad. There was a small development company who were dissatisfied with their current revision control system and practices, and who wanted a new system put in place and some training in how to use it. They were very happy with open source solutions and they were using a revision control system old enough there were a lot of scripts to migrate from it to almost any of the newer systems.

Apart from everyone having a different opinion on which system to migrate them to, I was fairly hopeful it was going to be an interesting project, or at the very least not terribly difficult.

To start with, I brought the discussion around to the customer's current usage patterns.

'Well, one of the problems that we have is disk space on the local developer workstations. We don't want a checkout of the code on every system, so we check out the code onto a file server and then everyone edits it from there'

This sounded extremely odd to me, but I assumed naively that people had their own checkouts in their own shell accounts.

'Oh no, we share the code out on a Samba share, and everyone maps it as a drive on their workstations'

Oh no.

It turns out that the entire office were mounting the same samba share read/write all using the same username and password, and all editing the files as the same user in the revision control system. There was absolutely no ability to figure out who was editing what, and conflicts happened regularly. When they did, work would grind to a halt for hours while everyone tried to figure out a compromise. What was worse, the disk space problem that had prompted this odd solution was mostly a factor of their lack of understanding of how their revision control system worked. Not everyone needed a full checkout of the repository but they hadn't seemed to yet figure out that you didn't need to pull the whole thing.

I made my escape quickly and when I got back to the office I ignored The Ticket.

Until the next new Sysadmin started, and then I assigned it to him.
