SVN to Git hash

In debugging, we often find a need to dial way back in the code to the Subversion (SVN) days. The repo that houses this code is in firemodels/fds-smv_deprecated. But it is hard in Git to find the old SVN numbers. This page provides a trick for getting there. Suppose you know the SVN number from running, say, version 6.1.2 of FDS and looking at the error file. It says, SVN 20564. You can look this number up in a list tracked in the current FDS repo store here:

Utilities/Misc/GoogleCode_Commit_Log.txt

Note that this log file is large and so GitHub will not display it. You will need to clone the repo and look at the file locally. When you do you can find the following:

r20564 | mcgratta | 2014-09-26 15:27:10 -0400 (Fri, 26 Sep 2014) | FDS Source: Revert change in 20337 and fix ADJUST_BURN_RATE problem.
