I can modify the code in the tree and push. This is mainly for kernel development. for that you can pass protocol=file to make the git fetcher use the file transport, see http://ao2.it/en/blog/2010/05/27/neat-compilerun-cycle-git-and-openembedded basically, in the .bb recipe, you can fetch from a local clone where you do your normal work. 2. If I work on a prerelease of some S/W drivers/Applications under NDA, then I cannot make that code publicly available but I still want to put that on my Internet accessible git server. Typicailly this is before the release of a new chip and info about the chip should not be made public before the chip is released. 3. I want to be able to ship something similar to the Angstrom setup scripts to someone else, and have them build an image, but it should not be available to anyone not accepted (without public key at the git server). maybe you can pass protocol=ssh as well to the git fetcher as well, but I haven't tried that, when you say R/W mode you are basically saying ssh transport for git, right? Let us know if that works. Ulf, any comments on Antonios ideas? I've just checked our own git repos and recipes; we're using SRC_URI's like: SRC_URI = git://gitosis@server-url/linux;protocol=ssh Then it is possible to work in that git clone as usual. Though, I've to mention that this is using oe-core, so there might be some differences in fetchers etc. /Anders ___ Openembedded-devel mailing list Openembedded-devel@lists.openembedded.org http://lists.linuxtogo.org/cgi-bin/mailman/listinfo/openembedded-devel

I do see the use of it though. externalsrc should handle everything except automatically fetching the source; for that you need to have your own local git clone (which of course can be r/w). I guess it depends on whether you expect to be sending such recipes to non-developers; for developers it ought not to be too much of a hassle to have their own local git clone. The only problem with having an r/w checkout you are doing development in under WORKDIR is that if you bitbake -c clean the recipe you will lose whatever you are working on - externalsrc avoids this.

Cheers, Paul I am working with a company, which OEMs their solution to other companies. They get tons of questions from those customers, and based on that I would like to avoid anything which requires manual intervention of the developer. As for cleaning out changes, it might happen, but I am prepared to take the risk. Today I am initializing a git after the extract anyway. I am sure I will use externalsrc for something. -- Best Regards Ulf Samuelsson u...@emagii.com +46 722 427437 ___ Openembedded-devel mailing list Openembedded-devel@lists.openembedded.org http://lists.linuxtogo.org/cgi-bin/mailman/listinfo/openembedded-devel
[oe] RFC: Support for R/W git in bitbake
Today bitbake supports read only git access in recipes. For various reasons, I would like to be able to do recipes which would check out in a read/write mode. I.E: have bitbake do git clone g...@emagii.com:myproject Did a prototype extension to bitbake that assumes the following URI wgit://emagii.com/myproject Any objections to such an extension? Suggestions for an alternative implementation? -- Best Regards Ulf Samuelsson u...@emagii.com ___ Openembedded-devel mailing list Openembedded-devel@lists.openembedded.org http://lists.linuxtogo.org/cgi-bin/mailman/listinfo/openembedded-devel
