Re: Migrating from Perforce to Subversion

Hi Jagtar, that line was commented out since it will fail if you've already done it (e.g., if you're already using git p4).

Looks like "svn: E205009: Local, non-commit operations do not take a log message or revision properties" is the first error. Try taking the -m option off the svn mkdir command. This script is > 5 years old so entirely possible some of the args have changed but I suspect the process is still usable.

Hello Mat,

I got a task to migrate P4 to SVN. I first tried with the p42svn, but it fails at one point or another. Now I am trying to do the same with your script, but getting errors.

1. Why (git p4 clone "${P4PATH}@all" "${PROJECT}.gitp4") is commented in your script. With comment it fails, but when i uncomment, it works but fails at later stage

2. Now if i run the script, it gives me errors. See the log

Here //depotv1.3 is my P4 Depot
svnwork/myproj is working directory of empty project

[root@IP]# bash -x p4togittosvn.sh //depotv1.3 svnwork/myproj
+ P4PATH=//depotv1.3
+ SVNPATH=svnwork/myproj
++ basename svnwork/myproj
+ PROJECT=myproj
+ git p4 clone //depotv1.3@all myproj.gitp4

Fantastic! I'm surprised it still works after all these years. Enjoy!

very nice - worked for me. I'll probably also use the git mirror to work locally but other corporate users like SVN so I'm good to go.

We haven't had to go as far as archiving yet, but I could see doing that once we finish our Rev1 and we want "pop the stack" as it were. The done column is handy since you can easily move tickets back if you realize there's a reason it's not quite done yet.

As for the color choice, it worked out that way because I picked the first one on the list as "In progress" and then decided easy/hard should be separate so I started at the end of the list. Not a lot of deep thought there :)

Estimate in the summary could work too, though the colors help make it very easy to get an idea of how much work you're looking at a glance. I worry that text wouldn't be as quickly parsable. Now, emoji on the other hand.... if only Trello would support that on summaries.

Evgeny Zislis — Fri, 27 Jun 2014 19:10:13 -0000

Would you archive the tasks that are done?
Also, why not use the red/orange/yellow for hard/easy? or add time estimates in the summaries for example.

Absolutely! I'll shoot you an email.

Mat, I love it. We should definitely talk since a few of us have conducted some similar Trello experiments. Would love to share notes.

Absolutely. I suppose that is a peril of having a comment on a 4 year old article! :-)

I hope they made it to git

The choice is about the team not the tool. This particular case was a team with a lot of context and infrastructure around subversion (this article was from 2009, btw. Pretty sure they're on git now). We picked up a project from a company that used perforce and this did the trick to pull it into the ecosystem.

"decided to use Git as an intermediary [to get to Subversion]" OK, that's properly messed up. Once you have migrated to git, you've arrived where you need to be. Why take the retrograde step to go down to (sucky old) Subversion?

Think: Why does git have such a wealth of good import tools?

It is because a lot of people want to be there, and to be there, they have to get there, and to get there, they need import tools.

Thanks! I should do some more blogging. Between work and devopscasts.com I've been pretty busy though. Working on a service-discovery-shootout episode now. Should be fun.

I know this is late, but congratulations on your move. Looking forward to some more "high-scale" posts.

Thanks, Mike! Yeah, seems that the only constant is change. :)

Re: A paragraph on sexism in computer science

Shantal — Mon, 03 Dec 2012 22:17:41 -0000

As a woman who has worked in the computer field/s for quite some time I would agree with the above post. Gender has nothing to do with graphic design or programming and its time that people stopped acting like it does. I wish I could count on one hand the number of times my presence has been requested in terms of the 'computer guy' or the 'graphic guy'. They are always a bit red faced when I declare 'that would be me'. Inaccurate conceptualizing often leads to an interesting reaction of shock.

Hehe... Well it was partly tongue-in-cheek. But it _is_ getting about due time for a new blog post.
