13:29 <yoyo[RKN]> moin

13:29 <yoyo[RKN]> is boinc source now official on github?

13:29 <yoyo[RKN]> so to fetch the latest version I must use git?

13:29 <MTughan> If Rom's announcement is anything to go by, yes.

13:29 <MTughan> Which I guess I'll have to do too...

13:30 <PovAddict> it will not be on github

13:30 <PovAddict> it's a git repository hosted on boinc.berkeley.edu

13:30 <yoyo[RKN]> ah, ok

13:31 <PovAddict> they have been using it for a few days and already made a mess in it

13:31 <yoyo[RKN]> to update my project I use git now, right?

13:36 <yoyo[RKN]> last svn checkin_notes are from 15. of October

13:37 * Tank_Master wonders when they will move to mericual

13:44 *** freakazoid0223 has quit IRC

14:01 <RomW> @Pov, only one mistake so far.  I'm still not sure how I managed to initiate a merge with the wxWidget30 branch.

14:01 <RomW> @Tank, hopefully never

14:03 <PovAddict> http://boinc.berkeley.edu/trac/changeset/c99db95/boinc http://boinc.berkeley.edu/trac/changeset/1365018/boinc

14:03 <Romulus> <http://tinyurl.com/9nrpvp9> (at boinc.berkeley.edu)

14:08 <RomW> okay, did not notice that

14:13 <yoyo[RKN]> to get now the sources, I must run git clone http://boinc.berkeley.edu/git/boinc.git ?

14:13 <Romulus> Title: Index of /git/boinc.git (at boinc.berkeley.edu)

14:13 <Tank_Master> what was that a responce to, Romulus?

14:14 <Tank_Master> RomW

14:15 <PovAddict> Tank_Master: moving to mercurial

14:15 <PovAddict> yoyo[RKN]: it's faster if you use the git:// URL

14:16 <Tank_Master> ah right :P

14:17 <yoyo[RKN]> ok

14:36 <yoyo[RKN]> how big is the git clone?

14:36 <yoyo[RKN]> I downloaded already 200MB and this is only 30% :(

14:37 *** si has quit IRC

14:40 <PovAddict> it's like 700MB

14:40 <yoyo[RKN]> why so much, my boinc svn folder is only 334M after compilation

14:41 <PovAddict> well, you're downloading the whole history, not the last version

14:41 <PovAddict> but I don't know why it's so big, my conversion attempts were always <300MB

14:42 <yoyo[RKN]> is there a way to get only the latest version

14:43 <PovAddict> yes, but I think then you can't update it

14:58 <yoyo[RKN]> will then the next clone be faster?

14:58 <PovAddict> next time you won't clone :)

14:59 <yoyo[RKN]> what will I do to get the latest version?

14:59 <PovAddict> "git fetch" downloads new changes from the server (taking deltas against *whatever* in the whole history you downloaded that helps the delta be smaller)

15:00 <PovAddict> "git pull" does "git fetch" plus actually merging what it downloaded into your working copy

15:02 <RomW> I think the download is more like 325mb, expands after that as the working copy is created

15:03 <yoyo[RKN]> Receiving objects:  56% (105801/188817), 506.83 MiB | 190 KiB/s

15:04 <RomW> what the heck

15:05 <RomW> I only uploaded a 350MB zip file to BOINC server after migration

15:05 <RomW> The pack file itself was just a few MB smaller

15:06 <PovAddict> could you run "git count-objects -v" on the server's repo?

15:08 <RomW> sh-4.2$ git count-objects -v

15:08 <RomW> count: 168

15:08 <RomW> size: 1916

15:08 <RomW> in-pack: 188984

15:08 <RomW> packs: 4

15:08 <RomW> size-pack: 885941

15:08 <RomW> prune-packable: 99

15:08 <RomW> garbage: 0

15:08 <PovAddict> there's 4 pack files adding up to 886MB

15:09 <RomW> Its grown

15:09 <RomW> that was quick

15:10 <PovAddict> hmm

15:10 <RomW> Is there supposed to be a regular script you are supposed to run to prune exess?

15:10 <RomW> excess?

15:11 <PovAddict> it shouldn't have grown this fast

15:11 <RomW> prune implies something can be deleted

15:11 <PovAddict> I mean, fe28a6b was probably big-ish because of the old checkin_notes files, but not 100MB

15:12 <RomW> even those were only 100k a pop

15:12 <PovAddict> are you sure the unpacked zip wasn't 800MB?

15:13 <RomW> I'll need to boot up the VM i used for the migration

15:13 <PovAddict> hmm

15:13 <PovAddict> check the timestamps of objects/pack/* in the server's repo?

15:15 *** mapreri has joined #boinc

15:19 <RomW> What the heck

15:21 *** paul_l has quit IRC

15:21 <PovAddict> ok, I'll assume the conversion did end up in those files :)

15:22 <PovAddict> run "git gc", it will put everything back into a single pack (including the 168 small unpacked objects)

15:23 *** mapreri has quit IRC

15:24 <RomW> Is there a way to specifically look at the contents of each pack file?

15:25 <RomW> Two pack files on the 15th is a bit fisky to me

15:25 <RomW> fishy

15:26 <Tank_Master> seem frisky? :P

15:26 <RomW> haha

15:27 <PovAddict> well either way I bet they are both badly compressed

15:27 <Tank_Master> and yes, thats how i read it :D

15:27 *** paul_l has joined #boinc

15:28 <PovAddict> git-fast-import makes crappy packfiles

15:29 <PovAddict> bah

15:29 <PovAddict> it keeps existing deltas

15:30 <PovAddict> git gc --aggressive # will ignore any existing deltas and make new ones from the raw objects, *and* will use a more aggressive delta-source-searching window than normal

15:43 <RomW> thats a huge change

15:43 <PovAddict> that's... better than I expected

15:44 <yoyo[RKN]> should I clone again or just pull?

15:44 <PovAddict> yoyo[RKN]: did you finish cloning?

15:44 <yoyo[RKN]> yes

15:45 <PovAddict> yoyo[RKN]: nothing changed in the repository content-wise

15:45 <PovAddict> yoyo[RKN]: if you want your local clone to be smaller, run git gc yourself

15:49 <PovAddict> "When packing a blob, fast-import always attempts to deltify against the last blob written. Unless specifically arranged for by the frontend [which svn-all-fast-export doesn't, btw], this will probably not be a prior version of the same file, so the generated delta will not be the smallest possible."

15:51 <RomW> cool

15:51 <RomW> repo down to 200mb with a current working tree

15:52 <Tank_Master> much more gooder

15:52 <RomW> well, clones are much faster anyway

15:52 <RomW> :)

15:52 <Tank_Master> lol and less server bandwith is used

16:02 <RomW> guess I better do that with all the other repos
