Hi, Currently I do not even have a working fg on my machine, but I continue to peek at the flightgear-devel list occasionally. Today I saw this discussion of moving the aircraft directories to individual SVN repos instead of git.
My experience with both svn and git is both minimal and old, and I may be misinterpreting what the problem is that needs solving. However, if you're going to consider creating separate repos in SVN for each aircraft, when everything else has been converted to git now, perhaps you should consider instead using "fossil", which is very git-like in some ways (clone,push,pull) but also like a traditional centralized VCS in some other ways. In particular, fossil's repository is a single, sqlite file. Although cloning is the normal method for copying it, you can copy that file just fine (as long as no one else is updating it at that instant) and it works fine. Afterwards, updating a local repo, using pull, involves an rsync-like protocol so it's fast. Fossil repositories can be converted to/from git repositories with a one-liner. (However I don't know how you would isolate, say, just the c172p directory from all the rest of the stuff in git.) If anyone thinks this might be relevant, just take a look at https://www.fossil-scm.org/index.html/doc/trunk/www/index.wiki This is a living instance of a fossil repository, BTW: the fossil binary, statically-linked except for libz, is ~900KB. Yet it includes a simple wiki, a *very* nice issue-tracking system, and a tiny web-server(!). Normally a developer interacts with fossil from the commandline, but the built-in web-server makes *exploring* what is in the repository, as well as creating bug reports and some documentation, a joy. Just for fun, and understanding that this would have to be done properly by someone with access to the full git repo with all its history, I yum-installed FlightGear-data on my Fedora system, and then did cp -r /usr/share/FlightGear/Aircraft /tmp and created Fossil repos for each of the included directories: shrdlu tmp $ ls Aircraft 777-200 bo105 dhc2 Generic j3cub ufo A6M2 c172p Dragonfly Instruments SenecaII UIUC b1900d CitationX f-14b Instruments-3d sopwithCamel ZLT-NT shrdlu tmp $ mkdir Repos shrdlu tmp $ cd Aircraft shrdlu Aircraft $ for i in * > do > echo "$i:" > fossil new ../Repos/$i.fossil > cd $i > fossil open ../../Repos/$i.fossil > fossil add . > fossil commit -m "Initial checkin" > fossil close > cd .. > done #Five times it paused to ask a question like this: # ./Models/Liveries/KLM.xml contains CR/NL line endings; commit anyhow (yes/no/all)?all #Otherwise it would have taken perhaps 30 seconds for all 18 repositories, #on my 5-year-old machine. shrdlu Aircraft $ cd .. shrdlu tmp $ du -sh Aircraft 12M Aircraft/777-200 4.5M Aircraft/A6M2 6.0M Aircraft/b1900d 3.0M Aircraft/bo105 17M Aircraft/c172p 5.8M Aircraft/CitationX 5.9M Aircraft/dhc2 1.6M Aircraft/Dragonfly 23M Aircraft/f-14b 816K Aircraft/Generic 14M Aircraft/Instruments 11M Aircraft/Instruments-3d 1.1M Aircraft/j3cub 6.6M Aircraft/SenecaII 22M Aircraft/sopwithCamel 216K Aircraft/ufo 8.2M Aircraft/UIUC 4.1M Aircraft/ZLT-NT shrdlu tmp $ ls -lh Repos total 68M -rw-r--r-- 1 dns dns 7.5M Jun 25 13:43 777-200.fossil -rw-r--r-- 1 dns dns 1.6M Jun 25 13:43 A6M2.fossil -rw-r--r-- 1 dns dns 3.3M Jun 25 13:43 b1900d.fossil -rw-r--r-- 1 dns dns 1.4M Jun 25 13:43 bo105.fossil -rw-r--r-- 1 dns dns 11M Jun 25 13:43 c172p.fossil -rw-r--r-- 1 dns dns 3.4M Jun 25 13:43 CitationX.fossil -rw-r--r-- 1 dns dns 3.2M Jun 25 13:43 dhc2.fossil -rw-r--r-- 1 dns dns 836K Jun 25 13:43 Dragonfly.fossil -rw-r--r-- 1 dns dns 11M Jun 25 13:44 f-14b.fossil -rw-r--r-- 1 dns dns 464K Jun 25 13:44 Generic.fossil -rw-r--r-- 1 dns dns 3.9M Jun 25 13:44 Instruments-3d.fossil -rw-r--r-- 1 dns dns 5.4M Jun 25 13:44 Instruments.fossil -rw-r--r-- 1 dns dns 457K Jun 25 13:44 j3cub.fossil -rw-r--r-- 1 dns dns 2.4M Jun 25 13:44 SenecaII.fossil -rw-r--r-- 1 dns dns 8.7M Jun 25 13:44 sopwithCamel.fossil -rw-r--r-- 1 dns dns 96K Jun 25 13:44 ufo.fossil -rw-r--r-- 1 dns dns 2.8M Jun 25 13:44 UIUC.fossil -rw-r--r-- 1 dns dns 1.4M Jun 25 13:44 ZLT-NT.fossil shrdlu tmp $ file Repos/777-200.fossil Repos/777-200.fossil: SQLite 3.x database shrdlu tmp $ du -sh Aircraft Repos 144M Aircraft 68M Repos shrdlu tmp $ Of course this is equivalent to just the "tip" of the git repository. Fossil uses deltas for versions internally, so it ought to be "competitive" on the full history, but only an experiment will prove that. Perhaps this is of some interest.
