Post subject:  svn vs. trunk ?
I'm thinking of having a test machine where I can load/compile some of the Mythtv developments (like HD-PVR) and play with them a little before the final release of 0.22.

I've been reading what I can find on svn and trunk. What is the difference?

My sense is that svn is a weekly compiled snapshot in time (with a specific version number) which is about as stable as you can get without waiting for the full release and that trunk is a daily-updated untrackable blob of code that is VERY bleeding edge and not very stable.

If I am right, I would want to play in the svn wading pool rather than in the trunk whitewater rapids.

Advice appreciated,
Eric

I'm no expert by any means but I believe that svn (subversion) is the delivery and tracking mechanizm, whereas trunk is a branch of the code your downloading. /branches/release-0-21-fixes/ gives you the latest of version .21 but since .22 has not been released yet you would be required to take from /trunk/. The numbers are revisions based on code changes and patches submitted. Haven't been brave enough to try trunk yet myself but have had fun patching 21-fixes for vdpau support.

http://svn.mythtv.org/trac/ has some information.

Technically, SVN is a tool, just like goofee says.

Practically, when people say SVN, they mean the dynamically changing latest source. i.e. trunk.

Ahh, I see. The branch that you get via SVN is the important factor.

So, if I were to subscribe to the .21 fixes branch via SVN, would the HD-PVR drivers and needed updates for the HD-PVR be in there?

I suspect I would NOT want to subscirbe my "production" Knoppmyth box (the box serving tv to us in our den) to any Mythtv branch via SVN, as parts of Mythtv would get broken, correct?

No. It's only in .22 (aka trunk)

If you know what you're doing, you can run trunk in a production situation. Keep in mind that things may be broken or incomplete, not to mention there will be a schema upgrade to you DB if you run trunk. All your mythboxen will need to run trunk/.22. If you take 0.21-fixes from SVN you likely will not have a problem if all your mythboxen are running some version of 0.21. However, I take no responsibility! :)

Post subject:  what's in .21 fixes?
So, what kinds of things are in the 0.21 fixes branch? Just fixes or does some new stuff find it's way into the fixes branch, too? Is it worth messing with?

Mostly bug fixes and enhancements.

Look at the commits and decide for yourself.

Post subject:  which .21 fixes are already in R5.5 ?
In R5.5, I'm looking at the Versions information in the Mythtv GUI (Knoppmyth menu item, then Version).

It says:

Mythtv version : 17686M,
Mythtv Branch : branches/release-0-21-fixes,
Library API : 0.21.20080304-1.
Network Protocol : 40

Do any of the numbers on that screen tell which slice in time (or SVN rev number) the code set included in R5.5 was taken from?

I'm looking at the .21 fixes branch screen http://svn.mythtv.org/trac/log/branches/release-0-21-fixes/ and trying to match up the R5.5 Versions info with one of those folders.
The closest match I see is a version 17684 (around July 1, 2008) - but no 17686M.

I'm just trying to figure out what .21-fixes we already have in R5.5 and which ones would get added.

I'm not sure why they tack the M on there, but the 17686 is indeed the svn revision number you are running. Go to:

http://svn.mythtv.org/trac/browser

Look under branches and then release-0-21-fixes. That's where the latest fixes resides.

HD-PVR support is only available in trunk. If you want to experiment, I suggest you start with the R6 release and go from there. That's the future.
