Template for Post Commit Hook Script to Get Files

[Jo...@sungard.com]

I am looking for an example of a post commit hook script that will 'get' a copy of the files that have changed in the revision being committed.  The intent is to populate a set of unix directories with the latest version of source code files.  These directories are in the "PROPATH"  used in our PROGRESS database test systems.  I would prefer examples of unix shell scripts but will also take a look at python or perl scripts. 

I googled a bit on this and I see a script that in turn calls a Hudson build script but we are not quite ready to do complete system builds. I also think a "bulk" svn export will not work for us either as we really only want the files that have changed in that revision.

Thanks.

Joe

Try "svn diff --summarize". For example here is a list of the files and directories changed in the 2.0 branch of MacPorts in December (apologies if my email client inserts any erroneous linebreaks):

$ svn diff --summarize https://svn.macosforge.org/repository/macports/branches/release_2_0 -r{2011-12-01}:{2011-12-31}
M       https://svn.macosforge.org/repository/macports/branches/release_2_0/base/src/pextlib1.0/tests/curl.tcl
M       https://svn.macosforge.org/repository/macports/branches/release_2_0/base/src/pextlib1.0/curl.c
 M      https://svn.macosforge.org/repository/macports/branches/release_2_0/base

svnlook changed

I am trying to figure out a way to get a list of files that have changed in a particular code line (branch or project) since a date or a revision.  Svnlook changed does not appear to accept a range of revisions. 

gold:/opt/subversion-1.7.1/bin> svnlook changed -r11034:11035 /dsi/subversion/test17/itrepos
svn: E205000: Invalid revision number supplied
gold:/opt/subversion-1.7.1/bin> svnlook changed -r11034:HEAD /dsi/subversion/test17/itrepos
svn: E205000: Invalid revision number supplied
gold:/opt/subversion-1.7.1/bin> svnlook changed -r11034 /dsi/subversion/test17/itrepos
UU  13.007/p.dev/buildTrade.p

Am I using the wrong syntax?  Is there a better way to get this information?

I suppose I could write a script that would recursively use svnlook on a series of revision numbers to build a complete list of changed paths between a selected revision and the HEAD revision of the repos.

Thanks

If you maintained a server-side working copy, running "svn update" on that working copy would only pull the changes. But if you really only want the files that have been changed, in order to do something special with them, then a different approach using svnlook may be desirable. You use "svnlook changed" to see what files changed, and you can use "svnlook cat" to extract them from the transaction to do things with them.

There have been a few such scripts posted here over the years. Here's one that tries to do a PHP syntax check on each PHP script committed:

http://svn.haxx.se/dev/archive-2008-01/0277.shtml

Perhaps that's a useful example to start with. This is a pre-commit hook but a post-commit hook is similar (you just deal with a revision instead of a transaction).
