Ah, I was working from miller's pi image. I've not been following what the differences between the various images are; I assumed that 9legacy and the pi image were close enough. What's the best way to get in sync on the pi? > I've installed the commands in a "git9" directory instead of "git", so it > doesn't conflict with the 9legacy git script ( > http://www.9legacy.org/9legacy/tools/git), which I still want to have > around for 'go get'.

I've thought about this a bit, and I think the approach I like most is a 'git/compat' script, which would leave you in a namespace where 'git' is a git-compatible-enough script that you could use for foreign software like go. Something like: #!/bin/rc bind -b /sys/lib/git/compat /bin Where /sys/lib/git/compat is a directory containing a 'git' script with all of the compatibility switches and mangling that's needed. But I don't have the 'git' script that we'd put there, and I don't know what sufficient compatibility looks like, so I'd need someone else to help out on that end. One notable omission in git9, by the way, is http clones. This is something go may want. I personally don't miss them, so I'm unlikely to get around to them soon, but I have a good idea of how to go about them, and I'd be happy to help out anyone interested in getting it done. -- 9fans: 9fans Permalink: https://9fans.topicbox.com/groups/9fans/T8be5c9b686015974-M7bd4cfb938079cb3351a52ee Delivery options: https://9fans.topicbox.com/groups/9fans/subscription
Re: [9fans] git9 on 9legacy
Very cool. I just tried and it seems to work. patch/apply rc-line-split This patch does not apply cleanly on 9legacy because of conflict with rc-badrunes patch (see http://www.9legacy.org/patch.html) which is included in 9legacy CD image. I've installed the commands in a "git9" directory instead of "git", so it doesn't conflict with the 9legacy git script ( http://www.9legacy.org/9legacy/tools/git), which I still want to have around for 'go get'. It's possible we can have a more complete git script with the help of git9. fhs -- 9fans: 9fans Permalink: https://9fans.topicbox.com/groups/9fans/T8be5c9b686015974-Mba1fca18cabf0967551ce54f Delivery options: https://9fans.topicbox.com/groups/9fans/subscription
[9fans] along the way...
I realized that the ape-erik patch was only available as a diff on 9legacy.org, and was missing inttypes.h for arm, so I fixed that omission, and imported it as something that you can get with patch/apply: patch/apply ape-erik I also ran into an issue with bad assembly in ape causing crashes with any code that called getfcr(). There was a variant of the code that implemented getfcr() uising VFP sitting in /sys/src/libc/getfcr.vfp.s, so I replaced the implementations in both libc and ape with it. It seems to work, and matches what we have on 9front. It's certainly no more wrong than what was there, but an extra pair of arm-familiar eyes would be appreciated on that patch. patch/apply rpi-getfcr-vfp Talking with miller off-list, making the default arm floating point use vfp seems like a good idea, which would probably make this patch the right choice. I couldn't figure out how to delete files with patch/create, so there will probably be a bit of junk left laying around from the ape-erik patch application. -- 9fans: 9fans Permalink: https://9fans.topicbox.com/groups/9fans/T12f163bbd73cfb63-M8302ba5adc55f0717dc94195 Delivery options: https://9fans.topicbox.com/groups/9fans/subscription

[9fans] git9 on 9legacy
I got a box running 9legacy running, and fixed the portability
issues in git9, since it didn't seem like anyone else was going
to do the work.
There are two patches needed which I put on sources:
- rc-line-split:
implement `delim{...} syntax for rc
- walk
port walk command to 9legacy.
Other than that, there were a couple of tweaks needed to
git9 itself: 9legacy has no '%z' format specifier, which
means that there's no way of printing pointer differences;
that's ok, they weren't really used for anything important.
And 9legacy awk is still an ape program, which means that
it uses /bin/sh. Some of the system calls that git9 was
doing from within awk used rc syntax. I pulled the code
up into awk, and made the commands shell agnostic.
So, to summarize:
# get dependencies
patch/apply rc-line-split
patch/apply walk
cd /sys/src
mk all
mk install
# get bootstrap version of git9
cd /tmp
hget http://github.com/oridb/git9/archive/master.tar.gz | tar xvz
cd git9-master
mk all
mk install
# now you can get stuff with git
git/clone git://github.com/oridb/git9
cd git9
mk install
