Unable to run on latest master

[gjaldon]

I tried running latest master of Canopy on my new Arch Linux install but get the ff error when trying to run ./main.native:

I checked the default engil/__blog repo and it has the .config/uuid file that it is looking for. Any idea what may have caused this? Is there additional setup I should beyond the following?

$ mirage configure
$ make depend
$ make

Which git (and mirage-git) are you using? Which remote protocol? Does it work if you use git://github.com/Engil/__blog.git (i.e. not smart http, but git protocol)?

[gjaldon]

I'm using git 1.10.0 and mirage-git 1.6.0 with OCaml 4.03.0. I tried using both http and git but get roughly the same errors. With git I'm getting the additional error:

WRN [canopy-store] failed pull Unix.Unix_error(Unix.EBADF, "check_descriptor", "")

Reported this issue at mirage/ocaml-git#205.

It seems that the problem is at least not in ocaml-git unix, since ogit cloning both URL seems to work on my station.
However I just encountered the same issue (5 is reserved) while trying to run latest Canopy/ocaml-git/mirage on Xen.
I suspect our dear old inflator.ml and latest Decompress release to be at play in this issue.
@dinosaure: Can you take a look at it ?
Do we have a proper alternative to our inflator somewhere upstream ?

//ping @dinosaure (see @Engil comment above)

[dinosaure]

Yes, I will check this day 👍 (sorry for the delay but, I have lot of work in other side).

See #87

If someone has time to adapt the new ocaml-git/irmin to canopy that would be super helpful. To get this going:

$ opam pin add git -n --dev
$ opam pin add git-http -n --dev
$ opam pin add git-mirage -n --dev
$ opam pin add irmin https://github.com/samoht/irmin.git#ngit
$ opam pin add irmin-git https://github.com/samoht/irmin.git#ngit
$ opam pin add irmin-mem https://github.com/samoht/irmin.git#ngit
$ opam pin add irmin-mirage https://github.com/samoht/irmin.git#ngit

I have a Canopy branch with compile with these patches: #95

No idea if that works fine, I haven't even started the unikernel.

No idea if that works fine, I haven't even started the unikernel.

So there's an issue in resolving Git uris.
