SVN Log Made Easier

Erik — Thu, 03 May 2007 18:16:00 +0000

So, I got tired of typing in the dates to find a range of log messages. Here’s my solution:


# In ~/.bashrc
svn-log() {
  case $1 in
    yesterday | yes | y) svn log -r {`date -d yesterday +"%Y-%m-%d"`}:{`date +"%Y-%m-%d"`};;
    *) echo "Invalid Option: $1";;
  esac
}

I plan to add more to this later.

Ignoring SVN and CVS files with rsync

Erik — Tue, 06 Mar 2007 21:07:00 +0000

I found out how to get rid of those pesky Subversion and CVS files as well as some other crappy files laying around when rsyncing. It’s really quite simple. It turns out the *-C* switch does this for you:


rsync -Cavrx ...

Very nice.

Switching SVN Locations

Erik — Wed, 21 Feb 2007 06:38:18 +0000

I moved some crap around in my repository the other day, and I felt the pain when I tried to update. Thankfully, the svn people have thought this thru already.


svn sw https://modzer0.cs.uaf.edu/repos/hank/code/rails/stockmaster .

At first this broke, so I had to do a temporary svn cp to resolve some missing crap. After that, it moved right over to the new location and I could update again.

If I had changed servers and not paths, I could have done this:


svn sw --relocate https://modzer0.cs.uaf.edu/repos/hank/code/rails/stockmaster \
https://modher0.cs.uaf.edu/repos/hank/code/rails/stockmaster .

All documented here.

Easy ACL Making for Subversion

Erik — Sun, 03 Sep 2006 12:51:43 +0000

So, I was messing around with Access Control Lists in svn today, and I needed
to fund out who the commiters were on each repository. I used svn log to do
this:


svn log https://modzer0.cs.uaf.edu/repos/hank | grep '^r[0-9]\{1,\}' | cut -d\| -f 2 | sort | uniq -c

This gets all the users and the number of commits they have:


      1  DevastatorIIC
     73  hank
     37  hardwarehank

How helpful.

Typo is broken, but I fixed Firefox

Erik — Wed, 23 Aug 2006 11:14:04 +0000

So, I upgraded Typo a few days ago, and just noticed today that all my links are broken because my relative_url_root is busted. I wonder what caused that. Anyway, on a better note, I fixed Firefox to open all new windows in new tabs instead. So much better. Here’s the fix:


browser.link.open newwindow.restriction = 0
browser.link.open newwindow = 3

Now, all the calls even from javascript will divert into the newwindow setting, which opens new tabs for everything. YAY!

This info was stolen from here

Update

Well, I contacted the #typo channel on freenode, and here’s the answer I got:


[11:39am|sprewell> hardwarehank, you should not be on trunk
[11:39am|sprewell> go back to 1230

So, here’s the solution I came to after screwing up a few times:

Move all your custom plugins (if any) from components/plugins to somewhere safe
Delete the components/plugins directory
rake migrate VERSION=50
svn up -r 1230
If it complains about not being able to create directories, just blow away those directories too after you back up anything custom.
Move things back in place
mongrel_rails restart

Magical SVN Remove

Erik — Sun, 06 Aug 2006 15:37:52 +0000

Have you ever wanted to batch remove some Subversion files? Try this on for size:


svn rm `svn stat | grep ! | sed -e 's/^\!\s\+//;s/$/ /' | tr -d '\n'`

That will remove all the entries from svn stat that start with !. Very handy. Took a few minutes to write (sed wouldn’t get rid of my newline, so I used tr …), but it’s worth it.

Fixed httpd hangings

Erik — Fri, 23 Jun 2006 02:34:30 +0000

So, Apache (httpd) was hanging for some reason, and it was really perplexing. I turned on the mod_status stuff and looked at the results, and found that the hung processes were caused when requests went to certain Subversion repositories. All I had to do was svnadmin recover them, and all was well.

Otherwise, I found an interesting function for ruby today…


#number_with_delimiter(number, delimiter)
number_with_delimiter(2000000)

Makes 2000000 look like 2,000,000. Amazing!

Simultaneous SVN Dump and Load with Netcat

Erik — Mon, 19 Jun 2006 01:17:35 +0000

I started by looking at the code from here.
Then, I decided I should use netcat instead of scp. Here’s the result:


cd 
svnadmin dump reponame | nc6 -x  7676


cd 
svnadmin create reponame
nc6 -x -l -p 7676 | svnadmin load reponame

Works like a charm – it’s awesome to have 2 windows open and watch the simultaneous dump and import – how hot.
