The overall issue here is that we need a better place to put in default webserving logic that is sensible for real-world page serving instead of just raw HTTP. Right now we have a few libraries in this stack: - Cohttp (the low level HTTP protocol) - Mirage-HTTP (the application of Cohttp to the Mirage networking stack) - Mirage-skeleton (sample basic applications) - Opium (a request routing web framework) - Mirage-Seal (a convenient CLI frontend to configuring static web apps) Mirage-Skeleton is being used right now (as Andrew did) to experiment with simple web applications, but shouldn't be the place where logic such as MIME detection is stored, as this should go into a library. Similarly, Mirage-Seal shouldn't have all this either, since it's a thin CLI layer that configures libraries. The right place ultimately for the MIME detection logic is either in Mirage-HTTP, which does very little at the moment aside from combine the CoHTTP and Mirage-TCP functors. The other possible place is Opium; I really enjoyed using Opium as a user for my own website, and so am keen to see that progress.

Interestingly, packet capture on eth0 shows the gw replying to arp requests. Also, removing ctx from HTTP.get that makes use of default resolver builds and runs but results in "name resolution failed unknown endpoint type", however the arp timeout and twice-dhcp process problems do not persist. Help is much appreciated.

I have a similar problem, please find the code (a revised http-fetch version) in the following repo:
https://github.com/lcoviedo/mirage-http-fetch

The unikernel only works fine when runs as a unix backend using socket network stack, otherwise I get the errors below (DHCP full process is run twice, and crashes after ARP timeout).

Interestingly, packet capture on eth0 shows the gw replying to arp requests. Also, removing ctx from HTTP.get that makes use of default resolver builds and runs but results in "name resolution failed unknown endpoint type", however the arp timeout and twice-dhcp process problems do not persist.

Help is much appreciated.

Hello

I am trying to run a static Mirage web server on a local Xen server.  

When I do 
curl 192.168.1.111
from dom0 it works fine.

When I try to access 192.168.1.111 from any other device on the network I get the errors below.

The cfg file includes this:
vif		=3D [ 'mac=3Dc0:ff:ee:aa:ff:ee,bridge=3Dxenbr0=E2=80=99 ]

I have also tried
vif		=3D [ 'bridge=3Dxenbr0=E2=80=99 ]

I have various other domu machines including an Ubuntu web server that have no problem responding to network requests from other devices on the network.

Any hints valued.

Interestingly, packet capture on eth0 shows the gw replying to arp requests. Also, removing ctx from HTTP.get that makes use of default resolver builds and runs but results in "name resolution failed unknown endpoint type", however the arp timeout and twice-dhcp process problems do not persist.

I have a similar problem, please find the code (a revised http-fetch version) in the following repo:
https://github.com/lcoviedo/mirage-http-fetch

The unikernel only works fine when runs as a unix backend using socket network stack, otherwise I get the errors below (DHCP full process is run twice, and crashes after ARP timeout).

Interestingly, packet capture on eth0 shows the gw replying to arp requests. Also, removing ctx from HTTP.get that makes use of default resolver builds and runs but results in "name resolution failed unknown endpoint type", however the arp timeout and twice-dhcp process problems do not persist.

Help is much appreciated.

Hello

I am trying to run a static Mirage web server on a local Xen server.  

When I do 
curl 192.168.1.111
from dom0 it works fine.

When I try to access 192.168.1.111 from any other device on the network I get the errors below.

The cfg file includes this:
vif		=3D [ 'mac=3Dc0:ff:ee:aa:ff:ee,bridge=3Dxenbr0=E2=80=99 ]

I have also tried
vif		=3D [ 'bridge=3Dxenbr0=E2=80=99 ]

I have various other domu machines including an Ubuntu web server that have no problem responding to network requests from other devices on the network.

Any hints valued.

Thanks for your reply Leonard. I opened a new thread since this seems to lead to a conduit related problem.

As it is done on:
https://github.com/mirage/ocaml-conduit/blob/master/tests/mirage/http-fetch/unikernel.ml#L28

create an empty conduit with protocols to be None (see the update unikernel.ml in: https://github.com/lcoviedo/mirage-http-fetch/blob/master/unikernel.ml )

However, when make the build fails with the following error:

File "unikernel.ml", line 30, characters 63-73:
Error: This expression is packed module, but the expected type is
'e Conduit_mirage.stackv4
Command exited with code 2.

Thanks

It looks like you're running two instances of the TCP/IP stack. One is
working and the other is failing. This is probably a bug in the mirage
tool, because you only created a single stack in your config.ml, but
check the generated main.ml to see what it actually did...

As a work-around, you could just pass the stack to your unikernel and
have it create conduit and the resolver.

One is working and the other is failing. This is probably a bug in the mirage tool, because you only created a single stack in your config.ml, but check the generated main.ml to see what it actually did... As a work-around, you could just pass the stack to your unikernel and have it create conduit and the resolver. > ARP: transmitting probe -> 10.0.20.1 > ARP: updating 10.0.20.1 -> 00:1b:d5:f4:1d:c4 > ARP: retrying 10.0.20.1 (n=3D2) > ARP: transmitting probe -> 10.0.20.1 > ARP: updating 10.0.20.1 -> 00:1b:d5:f4:1d:c4 > ARP: retrying 10.0.20.1 (n=3D3) > ARP: transmitting probe -> 10.0.20.1 > ARP: updating 10.0.20.1 -> 00:1b:d5:f4:1d:c4 > IP.output: arp timeout to gw 5.153.225.51 > Fatal error: exception > Ipv4.Make(Ethif)(Clock)(Time).Routing.No_route_to_destination_address(_) > Raised at file "src/core/lwt.ml", line 788, characters 22-23 > Called from file "lib/main.ml", line 58, characters 10-20 > Called from file "main.ml", line 107, characters 2-77 > Mirage exiting with status 2 > Do_exit called! > base is 0x46ff10 caller is 0x23e89d > base is 0x418df0 caller is 0x0 > base is 0x273c9b caller is 0x5241570000000000 > base is 0x65676172696d Page fault at linear address 656761726975, rip > 25a747, regs 000000000046fe28, sp 46fed0, our_sp 000000000046fdf0, code 0 > RIP: e030:[<000000000025a747>] > RSP: e02b:000000000046fed0 EFLAGS: 00010002 > RAX: 0000000000000017 RBX: 000065676172696d RCX: 00000000000004ba > RDX: 00000000000014bb RSI: 000000000046fd20 RDI: 0000000000000004 > RBP: 000000000046ff10 R08: 00000000000014bb R09: 0000000000000020 > R10: 0000000000000017 R11: 0000000000000010 R12: 0000000000000000 > R13: 0000000000000000 R14: 0000000000000000 R15: 0000000000000000 > base is 0x46ff10 caller is 0x23e89d > base is 0x418df0 caller is 0x0 > base is 0x273c9b caller is 0x5241570000000000 > base is 0x65676172696d Page fault in pagetable walk (access to invalid > memory=3F). > > -- Carlos Oviedo PhD student Network Systems Group University of Nottingham This message and any attachment are intended solely for the addressee and may contain confidential information.

Thanks for your reply Leonard. I opened a new thread since this seems to lead to a conduit related problem.

As it is done on:
https://github.com/mirage/ocaml-conduit/blob/master/tests/mirage/http-fetch/unikernel.ml#L28

create an empty conduit with protocols to be None (see the update unikernel.ml in: https://github.com/lcoviedo/mirage-http-fetch/blob/master/unikernel.ml )

However, when make the build fails with the following error:

File "unikernel.ml", line 30, characters 63-73:
Error: This expression is packed module, but the expected type is
'e Conduit_mirage.stackv4
Command exited with code 2.

Thanks

It looks like you're running two instances of the TCP/IP stack. One is
working and the other is failing. This is probably a bug in the mirage
tool, because you only created a single stack in your config.ml, but
check the generated main.ml to see what it actually did...

As a work-around, you could just pass the stack to your unikernel and
have it create conduit and the resolver.

https://github.com/mirage/ocaml-conduit/blob/master/tests/mirag= e/http-fetch/unikernel.ml#L28

create an empty conduit with protocols to be None (see the update unikernel.ml in: https://github.com/lcoviedo/mirage-http-fetch/blob/master/unike= rnel.ml )

However, when make the build fails with the following error:

File "unikernel.ml", line 30, characters 63-73:
Error: This expression is packed module, but the expected type is
'e Conduit_mirage.stackv4
Command exited with code 2.

The = conduit API for 0.8.4 was in flux in the last few days, it should be = stable now (and ready to release). I've just updated the http-fetch and = http-server tests to the latest API, this should work fine = now.

Apologies for the breakages, we = are still stabilising the API for the upcoming mirage 2.5.0 release = (with TLS support) -- almost all good now.

Best,
Thomas


Thanks

It looks like you're running two instances of the TCP/IP stack. One is
working and the other is failing. This is probably a bug in the mirage
tool, because you only created a single stack in your config.ml, = but
check the generated main.ml to see what it actually did...

As a work-around, you could just pass the stack to your unikernel and
have it create conduit and the resolver.

https://github.com/mirage/ocaml-conduit/blob/master/tests/mirag= e/http-fetch/unikernel.ml#L28

create an empty conduit with protocols to be None (see the update unikernel.ml in: https://github.com/lcoviedo/mirage-http-fetch/blob/master/unike= rnel.ml )

However, when make the build fails with the following error:

File "unikernel.ml", line 30, characters 63-73:
Error: This expression is packed module, but the expected type is
'e Conduit_mirage.stackv4
Command exited with code 2.

The = conduit API for 0.8.4 was in flux in the last few days, it should be = stable now (and ready to release). I've just updated the http-fetch and = http-server tests to the latest API, this should work fine = now.

Apologies for the breakages, we = are still stabilising the API for the upcoming mirage 2.5.0 release = (with TLS support) -- almost all good now.

Best,
Thomas


Thanks

It looks like you're running two instances of the TCP/IP stack. One is
working and the other is failing. This is probably a bug in the mirage
tool, because you only created a single stack in your config.ml, = but
check the generated main.ml to see what it actually did...

As a work-around, you could just pass the stack to your unikernel and
have it create conduit and the resolver.

Hi Jyotsna,

You might need to reinstall "mirage-xen-minios", if the compiler = you
originally built it with is no longer available.

It would be nice if it handled this automatically, but gcc doesn't
seem to include a pkg-config file, so it would mean putting the
detection logic in every package, I think.

Hi Jyotsna,

You might need to reinstall "mirage-xen-minios", if the compiler = you
originally built it with is no longer available.

It would be nice if it handled this automatically, but gcc doesn't
seem to include a pkg-config file, so it would mean putting the
detection logic in every package, I think.

Hi,

I would like to improve the API doc= umentation of the Mirage (and xapi-project) libraries, to make them quicker= and easier to understand. Currently I see the following problems:

- some libraries don't have good ocamldoc in .mli file= s (I'm guilty of this)
- we don't often generate the ocam= ldoc and publish it anywhere
- when the API changes, we don't= publish the previous versions or highlight the differences
- we = don't often create tutorial content to complement the API reference

I'd like to gather together ideas for improvement= and links to examples of good API documentation, which we could try to emu= late.

Regarding ocamldoc content, I think librarie= s like Daniel B=C3=BCnzli's (cc:d)=C2=A0cmdliner[0] show how nice it ca= n be. I also notice that the examples given in the docs are also in the tes= ts/ directory i.e. the same code was written both to test the library and d= ocument it -- this seems quite efficient.

As a= nother example Simon Beaumont (cc:d) pointed me at his ocaml-pci library[1]= which rebuilds the ocamldoc from travis and auto-uploads to github pages[2= ]-- is this the kind of thing we should attempt to standardise, say by addi= ng support for it into the common boilerplate ocaml-travisci-skeleton scrip= ts? Perhaps we should embed the version in the URL so we could publish mult= iple versions simultaneously?

I'm also a big f= an of the iocamljs notebooks (e.g. the coolest notebook ever[3]). It would = be really nice to write tutorials for each library to complement the API re= ference. Perhaps the notebooks should also be regenerated by the CI?

Note that the ocaml-travisci-skeleton scripts are moving toward being .ml files rather than pure scripts-- the sh front-ends now simply pull the necessary bits, install ocaml, and then build and execute their .ml counterpart. The .travis-mirage.ml contains the usual boilerplate for pushing build outputs back to Travis (per the various website examples). Ought to be straightforward to extend to also push doc build output.

Note that the ocaml-travisci-skeleton scripts are moving toward being .ml files rather than pure scripts-- the sh front-ends now simply pull the necessary bits, install ocaml, and then build and execute their .ml counterpart. The .travis-mirage.ml contains the usual boilerplate for pushing build outputs back to Travis (per the various website examples). Ought to be straightforward to extend to also push doc build output.

If not, creating one would be appreciated Carlos -- we do need to make sure that the Mirage tool handles multiple interfaces cleanly. -anil _______________________________________________ MirageOS-devel mailing list MirageOS-devel@lists.xenproject.org http://lists.xenproject.org/cgi-bin/mailman/listinfo/mirageos-devel From mirageos-devel-bounces@lists.xenproject.org Thu Jun 04 00:37:46 2015 Return-path: Envelope-to: archives@lists.xenproject.org Delivery-date: Thu, 04 Jun 2015 00:37:46 +0000 Received: from localhost ([127.0.0.1] helo=lists.xen.org) by lists.xen.org with esmtp (Exim 4.72) (envelope-from ) id 1Z0JA9-0007F3-Pw; Thu, 04 Jun 2015 00:37:37 +0000 Received: from mail6.bemta3.messagelabs.com ([195.245.230.39]) by lists.xen.org with esmtp (Exim 4.72) (envelope-from ) id 1Z0JA8-0007Ey-OS for mirageos-devel@lists.xenproject.org; Thu, 04 Jun 2015 00:37:36 +0000 Received: from [85.158.137.68] by server-9.bemta-3.messagelabs.com id 12/A7-17050-0DD9F655; Thu, 04 Jun 2015 00:37:36 +0000 X-Env-Sender: anil@recoil.org X-Msg-Ref: server-4.tower-31.messagelabs.com!1433378255!11663165!1 X-Originating-IP: [5.153.225.51] X-SpamReason: No, hits=1.4 required=7.0 tests=BODY_RANDOM_LONG, DATE_IN_PAST_03_06,RCVD_ILLEGAL_IP X-StarScan-Received: X-StarScan-Version: 6.13.16; banners=-,-,- X-VirusChecked: Checked Received: (qmail 19894 invoked from network); 4 Jun 2015 00:37:35 -0000 Received: from bark.recoil.org (HELO bark.recoil.org) (5.153.225.51) by server-4.tower-31.messagelabs.com with DHE-RSA-AES256-SHA encrypted SMTP; 4 Jun 2015 00:37:35 -0000 Received: from [172.31.52.75] (216.9.110.13 [216.9.110.13]); by bark.recoil.org (OpenSMTPD) with ESMTPSA id 63c0dff4; TLS version=TLSv1/SSLv3 cipher=ECDHE-RSA-AES256-SHA bits=256 verify=NO; Thu, 4 Jun 2015 01:37:33 +0100 (BST) Mime-Version: 1.0 (Mac OS X Mail 8.2 \(2098\)) From: Anil Madhavapeddy In-Reply-To: Date: Wed, 3 Jun 2015 19:59:06 +0100 Message-Id: <6DF912B4-75F0-4180-B3FC-0D230A82A4D9@recoil.org> References: <3205CE93-4104-4D5D-A8BE-4B854A97E1C4@recoil.org> To: Ahmed Ismail X-Mailer: Apple Mail (2.2098) Cc: mirageos-devel Subject: Re: [MirageOS-devel] CT 'xl create' - Loops and Device Model X-BeenThere: mirageos-devel@lists.xenproject.org X-Mailman-Version: 2.1.13 Precedence: list List-Id: Developer list for MirageOS List-Unsubscribe: , List-Post: List-Help: List-Subscribe: , Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit Sender: mirageos-devel-bounces@lists.xenproject.org Errors-To: mirageos-devel-bounces@lists.xenproject.org Hi Ahmed, That behaviour is indeed confusing, but at least explainable. When you specify a file, the toolstack is probably spinning up a qemu PV disk backend, and the direct device is probably going through blkback directly in the dom0 kernel. The exact behaviours for filesystem mounts have changed many many times in Xen in the past few years, so Dave Scott or Jon Ludlam could confirm this hypothesis better than me :-) -anil > On 2 Jun 2015, at 10:07, Ahmed Ismail wrote: > > Hi Anil, > > Thank you for your input. > Unfortunately, the img-based guest didn't get as far as needed for xenstore-ls to be able to give me any info. > I had checked Magnus' script, and it was really puzzling because it was the same way with which I had went about creating the non-working img file, and the working LV-based guest. > > Long story short, I finally figured it out. > It turns out that, for some reason, guest creation fails if you reference a file (the img) but works if you reference it as a device (i.e. the mounted img). > I don't mind the extra step ;). > > Thank you all for your help!

When you specify a file, the toolstack is probably spinning up a qemu PV disk backend, and the direct device is probably going through blkback directly in the dom0 kernel. The exact behaviours for filesystem mounts have changed many many times in Xen in the past few years, so Dave Scott or Jon Ludlam could confirm this hypothesis better than me :-) -anil > On 2 Jun 2015, at 10:07, Ahmed Ismail wrote: > > Hi Anil, > > Thank you for your input. > Unfortunately, the img-based guest didn't get as far as needed for xenstore-ls to be able to give me any info. > I had checked Magnus' script, and it was really puzzling because it was the same way with which I had went about creating the non-working img file, and the working LV-based guest. > > Long story short, I finally figured it out. > It turns out that, for some reason, guest creation fails if you reference a file (the img) but works if you reference it as a device (i.e. the mounted img). > I don't mind the extra step ;). > > Thank you all for your help! > > Best wishes, > -- > Ahmed > _______________________________________________ > MirageOS-devel mailing list > MirageOS-devel@lists.xenproject.org > http://lists.xenproject.org/cgi-bin/mailman/listinfo/mirageos-devel _______________________________________________ MirageOS-devel mailing list MirageOS-devel@lists.xenproject.org http://lists.xenproject.org/cgi-bin/mailman/listinfo/mirageos-devel From mirageos-devel-bounces@lists.xenproject.org Thu Jun 04 00:38:04 2015 Return-path: Envelope-to: archives@lists.xenproject.org Delivery-date: Thu, 04 Jun 2015 00:38:04 +0000 Received: from localhost ([127.0.0.1] helo=lists.xen.org) by lists.xen.org with esmtp (Exim 4.72) (envelope-from ) id 1Z0JAa-0007Hb-04; Thu, 04 Jun 2015 00:38:04 +0000 Received: from mail6.bemta3.messagelabs.com ([195.245.230.39]) by lists.xen.org with esmtp (Exim 4.72) (envelope-from ) id 1Z0JAY-0007HR-Oy for mirageos-devel@lists.xenproject.org; Thu, 04 Jun 2015 00:38:02 +0000 Received: from [85.158.137.68] by server-4.bemta-3.messagelabs.com id E7/DE-32406-AED9F655; Thu, 04 Jun 2015 00:38:02 +0000 X-Env-Sender: anil@recoil.org X-Msg-Ref: server-14.tower-31.messagelabs.com!1433378280!10485383!1 X-Originating-IP: [5.153.225.51] X-SpamReason: No, hits=2.5 required=7.0 tests=DATE_IN_PAST_03_06, GAPPY_SUBJECT,RCVD_ILLEGAL_IP X-StarScan-Received: X-StarScan-Version: 6.13.16; banners=-,-,- X-VirusChecked: Checked Received: (qmail 25776 invoked from network); 4 Jun 2015 00:38:00 -0000 Received: from bark.recoil.org (HELO bark.recoil.org) (5.153.225.51) by server-14.tower-31.messagelabs.com with DHE-RSA-AES256-SHA encrypted SMTP; 4 Jun 2015 00:38:00 -0000 Received: from [172.31.52.75] (216.9.110.13 [216.9.110.13]); by bark.recoil.org (OpenSMTPD) with ESMTPSA id 1b73fc02; TLS version=TLSv1/SSLv3 cipher=ECDHE-RSA-AES256-SHA bits=256 verify=NO; Thu, 4 Jun 2015 01:38:00 +0100 (BST) Mime-Version: 1.0 (Mac OS X Mail 8.2 \(2098\)) From: Anil Madhavapeddy In-Reply-To: <555778B0.9010309@luminar.eu.org> Date: Wed, 3 Jun 2015 20:37:03 +0100 Message-Id: References: <20150515.221024.1912056849687288780.Christophe.Troestler@umons.ac.be> <479284556.115403.1431776902075.JavaMail.yahoo@mail.yahoo.com> <555778B0.9010309@luminar.eu.org> To: Vincent Bernardoff X-Mailer: Apple Mail (2.2098) Cc: mirageos-devel@lists.xenproject.org Subject: Re: [MirageOS-devel] C.H.I.P.

It's worth noting that Martin Lucina's recent work on bare metal booting will eventually let us run on these A8 chips. The first target for this is x86 only, as ARM requires some extra work to wire up interrupts and so on, but it's all heading in the right direction. It seems fairly clear that most ARM chips wont have hardware virt support in the next few years (unlike x86 which picked up VT/SVM fairly rapidly), so this is something well worth continuing to work on. -anil _______________________________________________ MirageOS-devel mailing list MirageOS-devel@lists.xenproject.org http://lists.xenproject.org/cgi-bin/mailman/listinfo/mirageos-devel From mirageos-devel-bounces@lists.xenproject.org Thu Jun 04 00:38:04 2015 Return-path: Envelope-to: archives@lists.xenproject.org Delivery-date: Thu, 04 Jun 2015 00:38:04 +0000 Received: from localhost ([127.0.0.1] helo=lists.xen.org) by lists.xen.org with esmtp (Exim 4.72) (envelope-from ) id 1Z0JAa-0007Hb-04; Thu, 04 Jun 2015 00:38:04 +0000 Received: from mail6.bemta3.messagelabs.com ([195.245.230.39]) by lists.xen.org with esmtp (Exim 4.72) (envelope-from ) id 1Z0JAY-0007HR-Oy for mirageos-devel@lists.xenproject.org; Thu, 04 Jun 2015 00:38:02 +0000 Received: from [85.158.137.68] by server-4.bemta-3.messagelabs.com id E7/DE-32406-AED9F655; Thu, 04 Jun 2015 00:38:02 +0000 X-Env-Sender: anil@recoil.org X-Msg-Ref: server-14.tower-31.messagelabs.com!1433378280!10485383!1 X-Originating-IP: [5.153.225.51] X-SpamReason: No, hits=2.5 required=7.0 tests=DATE_IN_PAST_03_06, GAPPY_SUBJECT,RCVD_ILLEGAL_IP X-StarScan-Received: X-StarScan-Version: 6.13.16; banners=-,-,- X-VirusChecked: Checked Received: (qmail 25776 invoked from network); 4 Jun 2015 00:38:00 -0000 Received: from bark.recoil.org (HELO bark.recoil.org) (5.153.225.51) by server-14.tower-31.messagelabs.com with DHE-RSA-AES256-SHA encrypted SMTP; 4 Jun 2015 00:38:00 -0000 Received: from [172.31.52.75] (216.9.110.13 [216.9.110.13]); by bark.recoil.org (OpenSMTPD) with ESMTPSA id 1b73fc02; TLS version=TLSv1/SSLv3 cipher=ECDHE-RSA-AES256-SHA bits=256 verify=NO; Thu, 4 Jun 2015 01:38:00 +0100 (BST) Mime-Version: 1.0 (Mac OS X Mail 8.2 \(2098\)) From: Anil Madhavapeddy In-Reply-To: <555778B0.9010309@luminar.eu.org> Date: Wed, 3 Jun 2015 20:37:03 +0100 Message-Id: References: <20150515.221024.1912056849687288780.Christophe.Troestler@umons.ac.be> <479284556.115403.1431776902075.JavaMail.yahoo@mail.yahoo.com> <555778B0.9010309@luminar.eu.org> To: Vincent Bernardoff X-Mailer: Apple Mail (2.2098) Cc: mirageos-devel@lists.xenproject.org Subject: Re: [MirageOS-devel] C.H.I.P.

You can already do something similar: opam pin add foo https://github.com/mirage/foo.git#SHA1 Libraries in mirage-dev are in flux and people using it should expect breakage -- reporting these breakages on the list or on GitHub is *very* useful to converge to a stable state. Once stabilised, libraries are supposed to be properly release and migrate (in bulk) to opam-repository. Or we can have a mirage-dev-dev repository to avoid this but I would rather avoid this :p Thomas _______________________________________________ MirageOS-devel mailing list MirageOS-devel@lists.xenproject.org http://lists.xenproject.org/cgi-bin/mailman/listinfo/mirageos-devel From mirageos-devel-bounces@lists.xenproject.org Thu Jun 04 07:50:02 2015 Return-path: Envelope-to: archives@lists.xenproject.org Delivery-date: Thu, 04 Jun 2015 07:50:02 +0000 Received: from localhost ([127.0.0.1] helo=lists.xen.org) by lists.xen.org with esmtp (Exim 4.72) (envelope-from ) id 1Z0PuT-0000X0-Ft; Thu, 04 Jun 2015 07:49:53 +0000 Received: from mail6.bemta5.messagelabs.com ([195.245.231.135]) by lists.xen.org with esmtp (Exim 4.72) (envelope-from ) id 1Z0PuR-0000Wv-M0 for MirageOS-devel@lists.xenproject.org; Thu, 04 Jun 2015 07:49:51 +0000 Received: from [85.158.139.211] by server-12.bemta-5.messagelabs.com id 66/A5-25925-E1300755; Thu, 04 Jun 2015 07:49:50 +0000 X-Env-Sender: thomas.gazagnaire@gmail.com X-Msg-Ref: server-10.tower-206.messagelabs.com!1433404190!6422387!1 X-Originating-IP: [209.85.212.180] X-SpamReason: No, hits=0.0 required=7.0 tests= X-StarScan-Received: X-StarScan-Version: 6.13.16; banners=-,-,- X-VirusChecked: Checked Received: (qmail 24746 invoked from network); 4 Jun 2015 07:49:50 -0000 Received: from mail-wi0-f180.google.com (HELO mail-wi0-f180.google.com) (209.85.212.180) by server-10.tower-206.messagelabs.com with RC4-SHA encrypted SMTP; 4 Jun 2015 07:49:50 -0000 Received: by wiga1 with SMTP id a1so38553639wig.0 for ; Thu, 04 Jun 2015 00:49:50 -0700 (PDT) DKIM-Signature: v=1; a=rsa-sha256; c=relaxed/relaxed; d=gmail.com; s=20120113; h=sender:from:content-type:mime-version:subject:in-reply-to:date:cc :content-transfer-encoding:message-id:references:to; bh=asRSSUzTkuPutX+V9Ut0bWWLlFGrqbdmhzbJuozBUV4=; b=Lp3pIOiitKSQ8Xloop0R18puyvHokXrQSouD41wk/ewjyuJDV7YtCRAONJWykIRLYT hiHigVXhYh4ajJQ2ZaqKQpqECulNsZMET1zwQXgtOa+30YY/ZBr/JRKqIAvfjoFCG1eg bSLA1XYbO+seDlKcnFNmyCaERnN7+gRh7Yw+zwmvyRIcWR7v2GFDbHH9+0lwN3vjOXjw 260o5oEx0blI34J9ogyrwqkfHSzYhGIIlpT2pn7i1BgRt0VLpJEM9QG4t0dLIXNXZRjo ypzVXCbdKkKOs8Bp9OG5Pgf/m8VymGZDThsgN4B+zZQFucSCnVqco8txDFTQfkcORhl8 LCBA== X-Received: by 10.194.57.109 with SMTP id h13mr65781217wjq.67.1433404190051; Thu, 04 Jun 2015 00:49:50 -0700 (PDT) Received: from eduroam-138a.sophia.inria.fr (eduroam-138a.sophia.inria.fr.

You can already do something similar: opam pin add foo https://github.com/mirage/foo.git#SHA1 Libraries in mirage-dev are in flux and people using it should expect breakage -- reporting these breakages on the list or on GitHub is *very* useful to converge to a stable state. Once stabilised, libraries are supposed to be properly release and migrate (in bulk) to opam-repository. Or we can have a mirage-dev-dev repository to avoid this but I would rather avoid this :p Thomas _______________________________________________ MirageOS-devel mailing list MirageOS-devel@lists.xenproject.org http://lists.xenproject.org/cgi-bin/mailman/listinfo/mirageos-devel From mirageos-devel-bounces@lists.xenproject.org Thu Jun 04 08:22:56 2015 Return-path: Envelope-to: archives@lists.xenproject.org Delivery-date: Thu, 04 Jun 2015 08:22:56 +0000 Received: from localhost ([127.0.0.1] helo=lists.xen.org) by lists.xen.org with esmtp (Exim 4.72) (envelope-from ) id 1Z0QQO-0002VN-WC; Thu, 04 Jun 2015 08:22:52 +0000 Received: from mail6.bemta5.messagelabs.com ([195.245.231.135]) by lists.xen.org with esmtp (Exim 4.72) (envelope-from ) id 1Z0QQN-0002VI-0u for mirageos-devel@lists.xenproject.org; Thu, 04 Jun 2015 08:22:51 +0000 Received: from [85.158.139.211] by server-17.bemta-5.messagelabs.com id 86/12-01139-ADA00755; Thu, 04 Jun 2015 08:22:50 +0000 X-Env-Sender: buzzheavyyear@hotmail.com X-Msg-Ref: server-2.tower-206.messagelabs.com!1433406169!11716759!1 X-Originating-IP: [157.55.2.41] X-SpamReason: No, hits=0.2 required=7.0 tests=FORGED_HOTMAIL_RCVD, HTML_30_40,HTML_MESSAGE X-StarScan-Received: X-StarScan-Version: 6.13.16; banners=-,-,- X-VirusChecked: Checked Received: (qmail 6900 invoked from network); 4 Jun 2015 08:22:49 -0000 Received: from dub004-omc3s32.hotmail.com (HELO DUB004-OMC3S32.hotmail.com) (157.55.2.41) by server-2.tower-206.messagelabs.com with AES256-SHA encrypted SMTP; 4 Jun 2015 08:22:49 -0000 Received: from DUB128-W75 ([157.55.2.8]) by DUB004-OMC3S32.hotmail.com over TLS secured channel with Microsoft SMTPSVC(7.5.7601.22751); Thu, 4 Jun 2015 01:22:49 -0700 X-TMN: [8m//E9MFTt5u61yMh4PLizctO+1uxTj9] X-Originating-Email: [buzzheavyyear@hotmail.com] Message-ID: From: Nick Betteridge To: "mirageos-devel@lists.xenproject.org" Date: Thu, 4 Jun 2015 08:22:48 +0000 Importance: Normal MIME-Version: 1.0 X-OriginalArrivalTime: 04 Jun 2015 08:22:49.0255 (UTC) FILETIME=[A49DFB70:01D09E9F] Subject: [MirageOS-devel] cubie2 arm image loses mac X-BeenThere: mirageos-devel@lists.xenproject.org X-Mailman-Version: 2.1.13 Precedence: list List-Id: Developer list for MirageOS List-Unsubscribe: , List-Post: List-Help: List-Subscribe: , Content-Type: multipart/mixed; boundary="===============7668787597311937792==" Sender: mirageos-devel-bounces@lists.xenproject.org Errors-To: mirageos-devel-bounces@lists.xenproject.org --===============7668787597311937792== Content-Type: multipart/alternative; boundary="_608c7387-ec22-4cff-8181-059f4a51095a_" --_608c7387-ec22-4cff-8181-059f4a51095a_ Content-Type: text/plain; charset="iso-8859-1" Content-Transfer-Encoding: quoted-printable Each time I fire up a '2 and leave it on overnight and then try and ssh int= o the board the following morning=2C I get a no route to host.

Not sure if it's related, but when I tried customising my network settings I had various network problems that were fixed by 'apt-get purge xapi-xe xcp-networkd'. I didn't have time to look into the cause properly, but I think xcp-networkd fights with the OS for control of the network settings if you're not careful (try "xe pif-list params=all"). Probably one of the xapi people can explain what it's up to, if so. -- Dr Thomas Leonard http://roscidus.com/blog/ GPG: DA98 25AE CAD0 8975 7CDA BD8E 0713 3F96 CA74 D8BA _______________________________________________ MirageOS-devel mailing list MirageOS-devel@lists.xenproject.org http://lists.xenproject.org/cgi-bin/mailman/listinfo/mirageos-devel From mirageos-devel-bounces@lists.xenproject.org Thu Jun 04 08:31:19 2015 Return-path: Envelope-to: archives@lists.xenproject.org Delivery-date: Thu, 04 Jun 2015 08:31:19 +0000 Received: from localhost ([127.0.0.1] helo=lists.xen.org) by lists.xen.org with esmtp (Exim 4.72) (envelope-from ) id 1Z0QYY-00031S-OD; Thu, 04 Jun 2015 08:31:18 +0000 Received: from mail6.bemta3.messagelabs.com ([195.245.230.39]) by lists.xen.org with esmtp (Exim 4.72) (envelope-from ) id 1Z0QYX-00031N-Jx for mirageos-devel@lists.xenproject.org; Thu, 04 Jun 2015 08:31:17 +0000 Received: from [85.158.137.68] by server-13.bemta-3.messagelabs.com id 93/47-11060-4DC00755; Thu, 04 Jun 2015 08:31:16 +0000 X-Env-Sender: talex5@gmail.com X-Msg-Ref: server-10.tower-31.messagelabs.com!1433406675!12992603!1 X-Originating-IP: [209.85.217.178] X-SpamReason: No, hits=0.3 required=7.0 tests=RCVD_BY_IP X-StarScan-Received: X-StarScan-Version: 6.13.16; banners=-,-,- X-VirusChecked: Checked Received: (qmail 13203 invoked from network); 4 Jun 2015 08:31:16 -0000 Received: from mail-lb0-f178.google.com (HELO mail-lb0-f178.google.com) (209.85.217.178) by server-10.tower-31.messagelabs.com with RC4-SHA encrypted SMTP; 4 Jun 2015 08:31:16 -0000 Received: by lbcmx3 with SMTP id mx3so22610056lbc.1 for ; Thu, 04 Jun 2015 01:31:15 -0700 (PDT) DKIM-Signature: v=1; a=rsa-sha256; c=relaxed/relaxed; d=gmail.com; s=20120113; h=mime-version:in-reply-to:references:date:message-id:subject:from:to :cc:content-type; bh=21Xh63dW/Rql0v1BFvTcutie8+GsAGS5K0fapL1p86k=; b=gb4nvxmla2x2naXG3OkQujOyoXr9AGVHmwYiin9MhB8pEtNreDBvsH+APmG6YF3RI3 bIb8rG9u5Co2H2Xay7iMFBO8mQhZ00zhaAedqVHODpzZsCuyu0eqIQBXeNdh7hB5wwGK gT27d+yFiRZ/CrQKqreEOfm2nOVL43UPwbfnFI7qw0C8onQRCNkShd8p2WR4KoUSt7JZ 3DCgDEhE8ZTzbCWklZJyDG7nNk/gPnp3V1A6Ib8s3HIsHWC3fY/gIZcKjTEer75FWV3d 0I70nsT3Q9p4hMXIHTMVQcg+rjUV/6Nb+xcx89/EpOrjUTN6SnjZWO7DyzuZn0pEtMUF B5qA== MIME-Version: 1.0 X-Received: by 10.152.43.110 with SMTP id v14mr13281344lal.4.1433406675476; Thu, 04 Jun 2015 01:31:15 -0700 (PDT) Received: by 10.25.146.129 with HTTP; Thu, 4 Jun 2015 01:31:15 -0700 (PDT) In-Reply-To: References: Date: Thu, 4 Jun 2015 09:31:15 +0100 Message-ID: From: Thomas Leonard To: Nick Betteridge Cc: "mirageos-devel@lists.xenproject.org" Subject: Re: [MirageOS-devel] cubie2 arm image loses mac X-BeenThere: mirageos-devel@lists.xenproject.org X-Mailman-Version: 2.1.13 Precedence: list List-Id: Developer list for MirageOS List-Unsubscribe: , List-Post: List-Help: List-Subscribe: , Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit Sender: mirageos-devel-bounces@lists.xenproject.org Errors-To: mirageos-devel-bounces@lists.xenproject.org On 4 June 2015 at 09:22, Nick Betteridge wrote: > Each time I fire up a '2 and leave it on overnight and then try and ssh into > the board the following morning, I get a no route to host.

Not sure if it's related, but when I tried customising my n= etwork
settings I had various network problems that were fixed by 'apt-get
purge xapi-xe xcp-networkd'. I didn't have time to look into the ca= use
properly, but I think xcp-networkd fights with the OS for control of
the network settings if you're not careful (try "xe pif-list
params=3Dall"). Probably one of the xapi people can explain what it= 9;s up
to, if so.

I've not seen that mysel= f, but perhaps someone on the xen-api list (cc:d) could come up with a theo= ry?

I agree this feature would be very useful. Date is a reasonable way, but it would be better to use it to generate a manifest of package revisions and store that instead. I.e. the output of "opam install --show-actions" that tells you precisely what would be installed, except that you also want to see the full dependency tree. > There are times when it's useful to have as-yet-unreleased > packages/features available without wanting to be on the bleeding edge > of everything; or at least to have a convenient way to pull back from > the bleeding edge temporarily. Yeah. I think this should be possible to build as an OPAM plugin just by querying the package db. In Xen, I did something similar in 2007 with a 'manifest.hg' which collected together a forest of revisions from the 150 Mercurial repositories that formed the full XenServer distribution. We need something similar here now, with the ability to generate a precise dependency manifest for a mirage-app without doing so manually. -anil _______________________________________________ MirageOS-devel mailing list MirageOS-devel@lists.xenproject.org http://lists.xenproject.org/cgi-bin/mailman/listinfo/mirageos-devel From mirageos-devel-bounces@lists.xenproject.org Sat Jun 06 16:01:40 2015 Return-path: Envelope-to: archives@lists.xenproject.org Delivery-date: Sat, 06 Jun 2015 16:01:40 +0000 Received: from localhost ([127.0.0.1] helo=lists.xen.org) by lists.xen.org with esmtp (Exim 4.72) (envelope-from ) id 1Z1GXU-0001oe-Hp; Sat, 06 Jun 2015 16:01:40 +0000 Received: from mail6.bemta14.messagelabs.com ([193.109.254.103]) by lists.xen.org with esmtp (Exim 4.72) (envelope-from ) id 1Z1GXS-0001oZ-Sw for MirageOS-devel@lists.xenproject.org; Sat, 06 Jun 2015 16:01:38 +0000 Received: from [193.109.254.147] by server-11.bemta-14.messagelabs.com id E7/D3-30658-26913755; Sat, 06 Jun 2015 16:01:38 +0000 X-Env-Sender: anil@recoil.org X-Msg-Ref: server-10.tower-27.messagelabs.com!1433606497!20872600!1 X-Originating-IP: [5.153.225.51] X-SpamReason: No, hits=0.2 required=7.0 tests=RCVD_ILLEGAL_IP X-StarScan-Received: X-StarScan-Version: 6.13.16; banners=-,-,- X-VirusChecked: Checked Received: (qmail 3900 invoked from network); 6 Jun 2015 16:01:37 -0000 Received: from bark.recoil.org (HELO bark.recoil.org) (5.153.225.51) by server-10.tower-27.messagelabs.com with DHE-RSA-AES256-SHA encrypted SMTP; 6 Jun 2015 16:01:37 -0000 Received: from [192.168.0.119] (c-98-248-38-18.hsd1.ca.comcast.net [98.248.38.18]); by bark.recoil.org (OpenSMTPD) with ESMTPSA id 8f64df7c; TLS version=TLSv1/SSLv3 cipher=ECDHE-RSA-AES256-SHA bits=256 verify=NO; Sat, 6 Jun 2015 17:01:36 +0100 (BST) Mime-Version: 1.0 (Mac OS X Mail 8.2 \(2098\)) From: Anil Madhavapeddy In-Reply-To: Date: Sat, 6 Jun 2015 09:01:34 -0700 Message-Id: <5CF71249-6D64-41AA-8A1C-523F79CD1D2D@recoil.org> References: <7B0F0926-1372-4645-99A1-E9AA677A7F16@cl.cam.ac.uk> To: Richard Mortier X-Mailer: Apple Mail (2.2098) Cc: Thomas Gazagnaire , mirageos-devel Subject: Re: [MirageOS-devel] Random thought for an OPAM feature X-BeenThere: mirageos-devel@lists.xenproject.org X-Mailman-Version: 2.1.13 Precedence: list List-Id: Developer list for MirageOS List-Unsubscribe: , List-Post: List-Help: List-Subscribe: , Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit Sender: mirageos-devel-bounces@lists.xenproject.org Errors-To: mirageos-devel-bounces@lists.xenproject.org On 4 Jun 2015, at 03:34, Richard Mortier wrote: > > I think what I'm really saying is: a lightweight way to request a > consistent set of packages without needing to setup a dev opam repo. > Date seemed a reasonable way to index into that as I can usually > remember approximately the last time it worked (certainly better than > I can remember a set of package versions).

I agree this feature would be very useful. Date is a reasonable way, but it would be better to use it to generate a manifest of package revisions and store that instead. I.e. the output of "opam install --show-actions" that tells you precisely what would be installed, except that you also want to see the full dependency tree. > There are times when it's useful to have as-yet-unreleased > packages/features available without wanting to be on the bleeding edge > of everything; or at least to have a convenient way to pull back from > the bleeding edge temporarily.

Because these 6 bytes aren't expected, they're not actually given in the sequence number space (sent in a segment from .104 with ACK=true, seqno=1, ackno=1), and so when the server (.114) explicitly ACKs (ACK=true, seqno=1, ackno=7) them, things subsequently get confused with duplicate ACKs, apparently spurious retransmissions, etc. This is a bit weird because the client is CURL which one assumes is using the local stack which ought to be roughly correct (!)

Best wishes, Nicolas ---------- Forwarded message ---------- From: Nicolas Ojeda Bar Date: Sun, Jun 7, 2015 at 11:14 PM Subject: [ANN] RISC-V backend for the native-code OCaml compiler To: caml-list@inria.fr Dear list, I am happy two announce an ALPHA release of a new native-code backend for the OCaml compiler. It targets the RISC-V instruction set (http://riscv.org) being developed at UC Berkeley. The lowRISC project at the University of Cambridge (http://www.lowrisc.org) is developing open-source SoCs based on this instruction set. This release is in the form of a cross-compiler. It depends on the cross-compiling support recently added to 4.02.0+trunk. It outputs ELF binaries that can be simulated directly on the RISC-V ISA simulator (spike) or run natively in a suitable virtual machine. For detailed installation instructions, please visit: https://github.com/nojb/riscv-ocamlopt. The new backend is based on the old 3.12 MIPS backend and the currently shipping arm64 backend. Most compiler tests that can compile in the RISC-V environment pass successfully (including the "big" ones such as misc-bk, misc/hamming, misc/boyer, misc/nucleic, misc/bdd, etc.).

Best wishes, Nicolas ---------- Forwarded message ---------- From: Nicolas Ojeda Bar Date: Sun, Jun 7, 2015 at 11:14 PM Subject: [ANN] RISC-V backend for the native-code OCaml compiler To: caml-list@inria.fr Dear list, I am happy two announce an ALPHA release of a new native-code backend for the OCaml compiler. It targets the RISC-V instruction set (http://riscv.org) being developed at UC Berkeley. The lowRISC project at the University of Cambridge (http://www.lowrisc.org) is developing open-source SoCs based on this instruction set. This release is in the form of a cross-compiler. It depends on the cross-compiling support recently added to 4.02.0+trunk. It outputs ELF binaries that can be simulated directly on the RISC-V ISA simulator (spike) or run natively in a suitable virtual machine. For detailed installation instructions, please visit: https://github.com/nojb/riscv-ocamlopt. The new backend is based on the old 3.12 MIPS backend and the currently shipping arm64 backend. Most compiler tests that can compile in the RISC-V environment pass successfully (including the "big" ones such as misc-bk, misc/hamming, misc/boyer, misc/nucleic, misc/bdd, etc.). Limitations (some are due to the state of RISC-V software tools, some are due to limitations of the cross-compiling support in the current OCaml compiler, some just need work): - Only 64-bit for now (in particular the host has to be 64-bit as well) - Unix module is not yet supported - The current version uses the Newlib C library, which is somewhat less capable than glibc. - Shared library support may or may not work (has not been tested) Planned short term improvements (patches welcome!): - 32-bit support - cfi directives (and/or frame pointer inclusion) for easier debugging - switch to glibc - soft float support - Unix support Development is ongoing.

I was wondering, since you based your work on the old MIPS backend, how much work would it be to have a working mips32 native for ocaml ?

Would be interested to know if there also issues related to OCaml itself. No, it builds ocaml ok, but most of the mirage requirements wont build, some because eg it can't find libev that works with Musl, some things seem to want dynamic linking, some other less clear issues. Trying to build using the musl-gcc wrapper on a non Musl based distro is probably not going to work as there is no nice way to eg build libev against Musl. Fixing it to build ona Musl distro and then turning on static linking seems a better option.

Would be interested to know if there also issues related to OCaml itself. No, it builds ocaml ok, but most of the mirage requirements wont build, some because eg it can't find libev that works with Musl, some things seem to want dynamic linking, some other less clear issues. Trying to build using the musl-gcc wrapper on a non Musl based distro is probably not going to work as there is no nice way to eg build libev against Musl. Fixing it to build ona Musl distro and then turning on static linking seems a better option.

There are new releases of mirage-trace-viewer and mirage-profile, and updates to the Lwt tracing branch. Here's an example trace showing the new features: http://openmirage.org/html/trace-viewer.html?trace=good If you're using the 0install binary [2] of the trace viewer, you can update with: 0install update mtv The new viewer can still read old traces, but to use some of the new features you should "opam upgrade" to mirage-profile 0.5 and recompile your test program. Main new features - If a thread is marked with the new MProf.Trace.should_resolve call, then mark it as failed if it never resolved and set its end time to the end of the trace to make it more visible. This makes it much easier to find a thread when something was supposed to happen but didn't. - If one thread attempts to read from another, but it never completes, show a yellow arrow at the attempt to show what it's waiting for. By following these arrows you can discover the original stuck thread. - Double-click a thread to highlight it. This makes it easier to keep track of it when moving around. It also highlights any thread which this one merges into, and any threads which merge into this one, recursively. - The metric lines are now more visible, with a black outline. No more squinting :-) - The GTK viewer has a right-click pop-up menu, and the HTML viewer has a corresponding side panel that can be opened by clicking the new hamburger icon in the bottom left. - Display of metric lines can be toggled, either all at once by pressing Space, or individually via the menu/panel. - You can search for threads with a label matching some string (keyboard short-cut: '/'). I've updated the documentation page's example using the new version: http://openmirage.org/wiki/profiling Before, spotting the bug relied on comparing good and bad traces, but I think you could now reasonably find the bug using just the failed trace. I was also able to remove the apology about the unresolved threads being hard to see. Other changes - Some metrics now share their scales. e.g. tcp-to-ip and tcp-ackd-segs share a single scale. By default, the scale name is the metric name with any trailing '#...' part removed. So, 'tx_window#445' and 'tx_window#446' (the transmit window for two separate TCP connections) will share the same scale. - Trace files can now report absolute counter values, not just deltas. Scales now always go down to zero. - There are new callback thread types for Lwt.on_success, on_failure, etc. Previously, events from such callbacks were shown against the thread that registered the callback. This was confusing, and could cause redraw glitches if that thread ended before the callback events occured. - You can restrict the default metrics shown when using the HTML viewer API. - Updated opam file to use new configure option name. Reported by Luke Dunstan. - Adapt to latest io-page (Thomas Gazagnaire). - Install the xen plugin (Thomas Gazagnaire). - Updated Lwt repository link in mirage-profile README. Reported by Mindy Preston. - Failed threads are now drawn in red. - Positioning of metric lines was improved. - The view no longer aborts on unknown thread types (allows upgrading the format more easily).

This version fixes a few "interesting" issues: - [1] extra trailing bits in packets (produced by some misbehaving network drivers?) are now removed (and are not ACKed anymore by the stack) - [2] RST packets are now handled properly: related resources are now garbage collected, writes in a reset flow returns an error, packets are not ACKed anymore after a RST has been received, etc. - [3] the computation of the window size for out-of-order packets is fixed. This fixes weird retransmissions issues which happened sometimes. Moreover, there is a new logging system which can let the application turn on/off debug statements at runtime, for most of the Tcp modules (see [4] for the API and [5] for an example of use).

I'm = keeping the list in /cc as maybe other can hit the same problem and = might be interested in the (possible) solution.

I've = tried "ocamlfind query bytes" and find the bytes module. And I've tried = to add the library manually. It worked too.

Could I modify any config file to make the installation = through?
Or I have to wait for the new = version?

What= is your version of ocamlfind? (`opam info ocamlfind`) I think old = versions do not add the magic runes to do this automatically.  Can = you try to upgrade?

Best,
Thomas

I really appreciate your time = and patience. Thanks!

# Error: = Unbound module Bytes

Actually, I have installed the Bytes module. Here is "opam = list":

You seem to not have the "bytes" ocamlfind library = installed. You should have:

$ ocamlfind query bytes
/Users/thomas/.opam/mirage/lib/bytes

If not, try to reinstall = ocamlfind.
if yes, can you try to go in the build = directory of the package and try to add the library manually?

eval `opam config = env`
cd /root/.opam/4.01.0/build/hex.0.2.0/_build
ocamlfind ocamlc -c -g -annot -bin-annot = -package cstruct,bytes -I lib -o lib/hex.cmo lib/hex.m

If it works, I can release a new version of `ocaml-hex` with = an explicit dependency to bytes.

Best,
Thomas


# Installed packages for 4.01.0:
asn1-combinators       =  0.1.2  Combinators for expressing ASN.1 grammars in = OCaml

base-bytes =             legacy  Bytes = compatibility library distributed with ocamlfind
base-no-ppx           =    base  A pseudo-library to indicate lack of extension = points support

I think base-bytes is supposed to be the Bytes = module.  I googled this problem and nothing helped. Could anyone = help me out of this? I'm truly grateful for your = time!

How did you install OPAM (I notice it's 1.2.1rc2), and do you have the 'aspcud' binary installed? thanks, Anil _______________________________________________ MirageOS-devel mailing list MirageOS-devel@lists.xenproject.org http://lists.xenproject.org/cgi-bin/mailman/listinfo/mirageos-devel From mirageos-devel-bounces@lists.xenproject.org Thu Jun 11 14:05:20 2015 Return-path: Envelope-to: archives@lists.xenproject.org Delivery-date: Thu, 11 Jun 2015 14:05:20 +0000 Received: from localhost ([127.0.0.1] helo=lists.xen.org) by lists.xen.org with esmtp (Exim 4.72) (envelope-from ) id 1Z336R-0003iC-K1; Thu, 11 Jun 2015 14:05:07 +0000 Received: from mail6.bemta3.messagelabs.com ([195.245.230.39]) by lists.xen.org with esmtp (Exim 4.72) (envelope-from ) id 1Z336Q-0003hs-2d for mirageos-devel@lists.xenproject.org; Thu, 11 Jun 2015 14:05:06 +0000 Received: from [85.158.137.68] by server-1.bemta-3.messagelabs.com id 23/D7-10437-19599755; Thu, 11 Jun 2015 14:05:05 +0000 X-Env-Sender: martin@lucina.net X-Msg-Ref: server-7.tower-31.messagelabs.com!1434031504!15364320!1 X-Originating-IP: [62.176.169.44] X-SpamReason: No, hits=0.0 required=7.0 tests= X-StarScan-Received: X-StarScan-Version: 6.13.16; banners=-,-,- X-VirusChecked: Checked Received: (qmail 21826 invoked from network); 11 Jun 2015 14:05:04 -0000 Received: from smtp.lucina.net (HELO smtp.lucina.net) (62.176.169.44) by server-7.tower-31.messagelabs.com with DHE-RSA-AES256-SHA encrypted SMTP; 11 Jun 2015 14:05:04 -0000 Received: from nodbug.lucina.net (chello089173222227.chello.sk [89.173.222.227]) by smtp.lucina.net (Postfix) with ESMTPSA id 0D6F8122803 for ; Thu, 11 Jun 2015 16:04:54 +0200 (CEST) DKIM-Signature: v=1; a=rsa-sha256; c=relaxed/simple; d=lucina.net; s=dkim-201309; t=1434031494; bh=EsmeLGVy8NWwSJ0yPkksMp1+f/Gb8GptqK6E0wia4iU=; h=Date:From:To:Subject:From; b=PzmfahUWptHfS2riJbPoAHaAMz3yLY4DBFjbtbzIta5sge2PE7BbTtKoSj8vinYXv WfrkH+dsIIgR5cDJKeqlC/3ceIqb2LWf3EGgQlYIy/9mOK8TN9KrmYfDsJH9o6LczO b9LJ5tEGYZjQ18sK4ApCLnlj7hjfePJ6EleL9EFHI70xrmfcvZdqwjUhp61JNKO2bC ilqee+mp7a8lg3+Cn3+b1H1C6hJDZLE7CZyY9ZQ4p6vghSxVy8ToAoUBcVf+MtDhhI MFYYVyhsh6t8i4w1entg0pbeaQSahxSHioDr+lZoTmE9XvmytJh4bXpc5Xk37MtPJ5 3RD0/RqWlVjDw== Received: by nodbug.lucina.net (Postfix, from userid 1000) id 9D32D4C0E30; Thu, 11 Jun 2015 16:05:22 +0200 (CEST) Date: Thu, 11 Jun 2015 16:05:22 +0200 From: Martin Lucina To: mirageos-devel@lists.xenproject.org Message-ID: <20150611140522.GB30824@nodbug.lucina.net> Mail-Followup-To: mirageos-devel@lists.xenproject.org MIME-Version: 1.0 Content-Disposition: inline User-Agent: Mutt/1.5.21 (2010-09-15) Subject: [MirageOS-devel] "Unbound type constructor Conduit.ctx" building mirage-http for rumprun X-BeenThere: mirageos-devel@lists.xenproject.org X-Mailman-Version: 2.1.13 Precedence: list List-Id: Developer list for MirageOS List-Unsubscribe: , List-Post: List-Help: List-Subscribe: , Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit Sender: mirageos-devel-bounces@lists.xenproject.org Errors-To: mirageos-devel-bounces@lists.xenproject.org Hi all, I've been steadily adding more packages to my opam-rumprun repository [1] as I fix cross-compilation issues in the various build systems.

If you wait a little bit more, all these package w= ill be in opam. Thanks. I updated my -rumprun packages to those versions manually and I now have mirage-http built.

MIPS has actually got better recently, there are only two major ABIs that are supported, which are the two supported for Android, which are o32 on mips32r2, and n64. The Imagination CI20 is a reasonable dev board for the o32 target, easily available, n64 is still harder to get. n32 is not really important any more, most 64 bit targets run with full 64 bit userspace. OpenWrt is unfortunately largely on hardware without *any* floating point though, which makes it less compelling.

Detailed instructions for building "MiRump" unikernels can be found in the README in my opam-rumprun repository: https://github.com/mato/opam-rumprun Obligatory screenshot from running on KVM: http://ibin.co/24yZp6GhHCFU I've also added support to the mirage-seal tool for the rumprun target: https://github.com/mato/opam-rumprun#example-mirage-seal Next steps are getting the Ocaml-TLS stack working (builds, but not functional yet) and adding support for the OCaml TCP stack (requires integration with rumprun).

Very cool! I got the OCaml hello world example working, building in an Ubuntu 15.04 docker container and running on the host under kvm. Note: I had to "apt-get install gcc-4.8-multilib", otherwise the initial "opam sw" failed. I was able to run it with: $ qemu-system-i386 -kernel ./hello.bin -append '{"cmdline": "../../hello.bin"}' (the "rumprun" script worked too, but running it this way made things clearer to me) I also tested mirage-skeleton/console, which worked but ran rather fast (it's supposed to wait 1s between each print).

I've started making a patch to try to use the RRD code-- I think it's possible, but the interface needs a bit of tidying (for example, some of the functions take a "domid" which is clearly part of the xapi application logic, but it's ended up in slightly the wrong place.)

After refactoring the server code to use the mirage interfaces rather than Unix & friends directly, I've got it compiling to the xen backend. I've been using nix[1] to build my project, so while getting stuff working I have been using opam instead to maximise my chance of it working. But now that it does, I'd like to get it working under `nix` as well. Most of it is just grunt work, as the mirage libraries & dependencies seem to build without issue (yay!), but when it comes to linking stub libraries I'm having some trouble. As I understand it, some (most?) c stubs will need cross-compilation for a xen (minios?) target before they can be linked into a xen unikernel. You've made *-xen opam package variants for the libraries needed for nocrypto - zarith, gmp, etc. In trying to recreate these I feel like I'm doing just the same as the opam packages - based on the opam repo I'm applying the exact same patches, running the same build script (modulo $PKG_CONFIG_PATH), etc. But I still can't get gmp to build. It gets to the linking stage, and I get a screenful of undefined symbols, primarily "_ctype" and "printk". I've uploaded the full log[2]. if that helps. I can't really tell which side of the problem this is - should gmp not be referencing these symbols (maybe I'm missing some compile flags)? or should the symbols be found somewhere, and I'm failing to link in some important library? In either case it's hard to tell where to go from here, since I can't see anything too suspicious in the logs, and I'm trying my best to do the same thing as `opam` would. Any pointers?

After refactoring the server code to use the mirage interfaces rather than Unix & friends directly, I've got it compiling to the xen backend. I've been using nix[1] to build my project, so while getting stuff working I have been using opam instead to maximise my chance of it working. But now that it does, I'd like to get it working under `nix` as well. Most of it is just grunt work, as the mirage libraries & dependencies seem to build without issue (yay!), but when it comes to linking stub libraries I'm having some trouble. As I understand it, some (most?) c stubs will need cross-compilation for a xen (minios?) target before they can be linked into a xen unikernel. You've made *-xen opam package variants for the libraries needed for nocrypto - zarith, gmp, etc. In trying to recreate these I feel like I'm doing just the same as the opam packages - based on the opam repo I'm applying the exact same patches, running the same build script (modulo $PKG_CONFIG_PATH), etc. But I still can't get gmp to build. It gets to the linking stage, and I get a screenful of undefined symbols, primarily "_ctype" and "printk". I've uploaded the full log[2]. if that helps. I can't really tell which side of the problem this is - should gmp not be referencing these symbols (maybe I'm missing some compile flags)? or should the symbols be found somewhere, and I'm failing to link in some important library? In either case it's hard to tell where to go from here, since I can't see anything too suspicious in the logs, and I'm trying my best to do the same thing as `opam` would. Any pointers? Cheers, - Tim.

Any pointers? Hi Tim, I don't know much about the gmp build process, but if you have a good (opam) build and a bad (nix) one, I guess you can just compare the two environments. e.g. are the missing symbols present in the good build? Does the nix one build if you point PKG_CONFIG_PATH at the opam installation, etc? Many of the errors are coming from libtests.a - should it even be building the tests for a cross-compile (I don't know)? > Cheers, > - Tim. > > > [0]: https://github.com/gfxmonk/passe > [1]: http://nixos.org/nix/ > [2]: https://gist.github.com/gfxmonk/e981bfb381328cb11af8 > > _______________________________________________ > MirageOS-devel mailing list > MirageOS-devel@lists.xenproject.org > http://lists.xenproject.org/cgi-bin/mailman/listinfo/mirageos-devel -- Dr Thomas Leonard http://roscidus.com/blog/ GPG: DA98 25AE CAD0 8975 7CDA BD8E 0713 3F96 CA74 D8BA _______________________________________________ MirageOS-devel mailing list MirageOS-devel@lists.xenproject.org http://lists.xenproject.org/cgi-bin/mailman/listinfo/mirageos-devel From mirageos-devel-bounces@lists.xenproject.org Mon Jun 15 16:48:55 2015 Return-path: Envelope-to: archives@lists.xenproject.org Delivery-date: Mon, 15 Jun 2015 16:48:55 +0000 Received: from localhost ([127.0.0.1] helo=lists.xen.org) by lists.xen.org with esmtp (Exim 4.72) (envelope-from ) id 1Z4XYt-0001my-UJ; Mon, 15 Jun 2015 16:48:39 +0000 Received: from mail6.bemta3.messagelabs.com ([195.245.230.39]) by lists.xen.org with esmtp (Exim 4.72) (envelope-from ) id 1Z4XYt-0001mp-4S for mirageos-devel@lists.xenproject.org; Mon, 15 Jun 2015 16:48:39 +0000 Received: from [85.158.137.68] by server-4.bemta-3.messagelabs.com id 97/B1-32406-6E10F755; Mon, 15 Jun 2015 16:48:38 +0000 X-Env-Sender: talex5@gmail.com X-Msg-Ref: server-7.tower-31.messagelabs.com!1434386916!16441459!1 X-Originating-IP: [209.85.213.43] X-SpamReason: No, hits=0.3 required=7.0 tests=RCVD_BY_IP X-StarScan-Received: X-StarScan-Version: 6.13.16; banners=-,-,- X-VirusChecked: Checked Received: (qmail 14607 invoked from network); 15 Jun 2015 16:48:37 -0000 Received: from mail-yh0-f43.google.com (HELO mail-yh0-f43.google.com) (209.85.213.43) by server-7.tower-31.messagelabs.com with RC4-SHA encrypted SMTP; 15 Jun 2015 16:48:37 -0000 Received: by yhid80 with SMTP id d80so46880201yhi.1 for ; Mon, 15 Jun 2015 09:48:36 -0700 (PDT) DKIM-Signature: v=1; a=rsa-sha256; c=relaxed/relaxed; d=gmail.com; s=20120113; h=mime-version:in-reply-to:references:date:message-id:subject:from:to :cc:content-type; bh=+N5D9yVOmnBgFWfw5s47K3vzPqVFbeZfL9Orgw9UjDs=; b=JGRDH0PcYFZW+LyuR+Rj0+wgmLwdqYd20w3pTYhEtNive+//UNGVYT/m5yIF2g09Vv g3NFHN0aP9fh2fjuDlJk7plXs+qjTyD1kus/02JLoLJvMvhSMc8DKKRARIPkMaLJ/5t/ CRmmGnv+d09mDflUQqJcKjI/k2aurfeLhk0D7diOq8esBaHjdqj7buh52hmG8YlV12EP JYAzZuYSv4Y4l5ZFIwwRp3voammUNTqDG6plmRqOUlRlq3OrWdeZn3ds8yc3qP4/OdCo LXK2svJrxEHCt0UZD2LPDtN4Kxo+nffvRKqDw4K31VVNEEAUlqYoR52vs8sVwdVLvU98 tQsQ== MIME-Version: 1.0 X-Received: by 10.52.129.100 with SMTP id nv4mr41546679vdb.43.1434386916302; Mon, 15 Jun 2015 09:48:36 -0700 (PDT) Received: by 10.31.95.6 with HTTP; Mon, 15 Jun 2015 09:48:36 -0700 (PDT) In-Reply-To: References: Date: Mon, 15 Jun 2015 17:48:36 +0100 Message-ID: From: Thomas Leonard To: Tim Cuthbertson Cc: "mirageos-devel@lists.xenproject.org" Subject: Re: [MirageOS-devel] Compiling gmp-xen with nixpkgs X-BeenThere: mirageos-devel@lists.xenproject.org X-Mailman-Version: 2.1.13 Precedence: list List-Id: Developer list for MirageOS List-Unsubscribe: , List-Post: List-Help: List-Subscribe: , Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit Sender: mirageos-devel-bounces@lists.xenproject.org Errors-To: mirageos-devel-bounces@lists.xenproject.org On 15 June 2015 at 13:58, Tim Cuthbertson wrote: > Hi all, > > After getting acquainted with some of the sample applications, I've > been trying to get the server component of a relatively small project > of mine[0] running under mirage. > > After refactoring the server code to use the mirage interfaces rather > than Unix & friends directly, I've got it compiling to the xen > backend. > > I've been using nix[1] to build my project, so while getting stuff > working I have been using opam instead to maximise my chance of it > working.

I tracked down where `opam` stored its build logs (which doesn't seem to be documented anywhere, so I resorted to `lsof`), and did a diff of the outputs. Turns out I was doing exactly what `opam` does, but I forgot that `nix` by default runs `make test` after building. So actually it had built fine, but the tests (as Thomas suspected) simply don't compile in this configuration. So that built just fine once I disabled the tests - I can't tell if it all works yet as I've got some more missing dependencies to deal with, but it's looking good. When I'm done, how do you folks feel about me submitting these nix packages to the official nixpkgs repo? I assume you only want to support `opam` officially, but nix users are used to being on an unsupported environment ;). I'm hoping the churn of new packages shouldn't be too hard for me to keep up with at this point? Making the 20+ new packages I needed for this took me less than a day, and updates to existing packages should be pretty simple. Cheers, - Tim.

Another solution could be to define an ocamlfind predicate such as "notebook" which will automatically add the printers from the META file. archive(notebook) += "xyz_iocaml_printers.cma" For iocamljs the kernel would then need to be compiled with "-predicates notebook" added to the ocamlfind build command. For bytecode iocaml you would need to add "Topfind.add_predicates [ "notebook" ];" to the init file. I am not so sure this second solution will play all that nicely with the likes of oasis though - to do it properly the tools will need to be taught about the notebook predicate in the same way they handle the toploop predicate currently. -Andy _______________________________________________ MirageOS-devel mailing list MirageOS-devel@lists.xenproject.org http://lists.xenproject.org/cgi-bin/mailman/listinfo/mirageos-devel From mirageos-devel-bounces@lists.xenproject.org Wed Jun 17 10:29:38 2015 Return-path: Envelope-to: archives@lists.xenproject.org Delivery-date: Wed, 17 Jun 2015 10:29:38 +0000 Received: from localhost ([127.0.0.1] helo=lists.xen.org) by lists.xen.org with esmtp (Exim 4.72) (envelope-from ) id 1Z5AbA-0004JD-Qs; Wed, 17 Jun 2015 10:29:36 +0000 Received: from mail6.bemta3.messagelabs.com ([195.245.230.39]) by lists.xen.org with esmtp (Exim 4.72) (envelope-from ) id 1Z5Ab9-0004Iq-UH for mirageos-devel@lists.xenproject.org; Wed, 17 Jun 2015 10:29:36 +0000 Received: from [85.158.137.68] by server-11.bemta-3.messagelabs.com id 4B/E7-16518-F0C41855; Wed, 17 Jun 2015 10:29:35 +0000 X-Env-Sender: andy.ray@ujamjar.com X-Msg-Ref: server-14.tower-31.messagelabs.com!1434536974!14629275!1 X-Originating-IP: [31.172.243.2] X-SpamReason: No, hits=0.3 required=7.0 tests=RCVD_BY_IP X-StarScan-Received: X-StarScan-Version: 6.13.16; banners=-,-,- X-VirusChecked: Checked Received: (qmail 20864 invoked from network); 17 Jun 2015 10:29:34 -0000 Received: from vm12460.vps.tagadab.com (HELO www.ujamjar.com) (31.172.243.2) by server-14.tower-31.messagelabs.com with DHE-RSA-AES256-SHA encrypted SMTP; 17 Jun 2015 10:29:34 -0000 Received: from mail-wi0-f172.google.com (mail-wi0-f172.google.com [209.85.212.172]) (using TLSv1 with cipher RC4-SHA (128/128 bits)) (No client certificate requested) by www.ujamjar.com (Postfix) with ESMTPSA id 7B6CF1243B4 for ; Wed, 17 Jun 2015 11:29:07 +0100 (BST) Received: by wifx6 with SMTP id x6so47993463wif.0 for ; Wed, 17 Jun 2015 03:29:13 -0700 (PDT) MIME-Version: 1.0 X-Received: by 10.180.7.169 with SMTP id k9mr16595151wia.84.1434536953494; Wed, 17 Jun 2015 03:29:13 -0700 (PDT) Received: by 10.27.63.70 with HTTP; Wed, 17 Jun 2015 03:29:13 -0700 (PDT) In-Reply-To: <1CD19A34-8D56-48F9-98C8-375AAACC28C8@recoil.org> References: <1CD19A34-8D56-48F9-98C8-375AAACC28C8@recoil.org> Date: Wed, 17 Jun 2015 11:29:13 +0100 Message-ID: From: Andy Ray To: Anil Madhavapeddy Cc: "mirageos-devel@lists.xenproject.org" Subject: Re: [MirageOS-devel] pretty charts from OCaml and js_of_ocaml X-BeenThere: mirageos-devel@lists.xenproject.org X-Mailman-Version: 2.1.13 Precedence: list List-Id: Developer list for MirageOS List-Unsubscribe: , List-Post: List-Help: List-Subscribe: , Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit Sender: mirageos-devel-bounces@lists.xenproject.org Errors-To: mirageos-devel-bounces@lists.xenproject.org > > Andy: this seems like a good time to figure out how to best embed HTML > toplevel printers in IOCamlJS from these sorts of libraries (it also came up > in the URI library, which wanted to embed a hyperlink).

I've updated CueKeeper to run against Irmin master, and it now works without any hacks :-) Thanks! >> [1] https://github.com/mirage/irmin/issues/204 >> [2] https://github.com/mirage/irmin/issues/205 > [3] https://github.com/mirage/irmin/issues/117 -- Dr Thomas Leonard http://roscidus.com/blog/ GPG: DA98 25AE CAD0 8975 7CDA BD8E 0713 3F96 CA74 D8BA _______________________________________________ MirageOS-devel mailing list MirageOS-devel@lists.xenproject.org http://lists.xenproject.org/cgi-bin/mailman/listinfo/mirageos-devel From mirageos-devel-bounces@lists.xenproject.org Fri Jun 19 12:12:47 2015 Return-path: Envelope-to: archives@lists.xenproject.org Delivery-date: Fri, 19 Jun 2015 12:12:47 +0000 Received: from localhost ([127.0.0.1] helo=lists.xen.org) by lists.xen.org with esmtp (Exim 4.72) (envelope-from ) id 1Z5vA1-0002cj-EY; Fri, 19 Jun 2015 12:12:41 +0000 Received: from mail6.bemta5.messagelabs.com ([195.245.231.135]) by lists.xen.org with esmtp (Exim 4.72) (envelope-from ) id 1Z5v9z-0002bz-Rs; Fri, 19 Jun 2015 12:12:39 +0000 Received: from [85.158.139.211] by server-9.bemta-5.messagelabs.com id 7D/B7-21325-73704855; Fri, 19 Jun 2015 12:12:39 +0000 X-Env-Sender: lars.kurth.xen@gmail.com X-Msg-Ref: server-13.tower-206.messagelabs.com!1434715957!15498439!1 X-Originating-IP: [209.85.212.177] X-SpamReason: No, hits=0.1 required=7.0 tests=HTML_50_60,HTML_MESSAGE X-StarScan-Received: X-StarScan-Version: 6.13.16; banners=-,-,- X-VirusChecked: Checked Received: (qmail 15478 invoked from network); 19 Jun 2015 12:12:37 -0000 Received: from mail-wi0-f177.google.com (HELO mail-wi0-f177.google.com) (209.85.212.177) by server-13.tower-206.messagelabs.com with RC4-SHA encrypted SMTP; 19 Jun 2015 12:12:37 -0000 Received: by wicgi11 with SMTP id gi11so16803299wic.0; Fri, 19 Jun 2015 05:12:37 -0700 (PDT) DKIM-Signature: v=1; a=rsa-sha256; c=relaxed/relaxed; d=gmail.com; s=20120113; h=from:content-type:subject:message-id:date:to:mime-version; bh=3OzPmVVvqESqAROl72tI7L+TeqUyHkB6+D0W+w0nf8U=; b=x6MJLslv0banfGNoR76sU24IBN16GZEj48zumiMRrqQwfOF4TKfdDLF4gnQL8O7dd0 9vcc3fQT0IbkE9p1iIBQQzWeDqT5w0yOnzfHuvV/+hGxdfj4GbyrhjHM+FWnRFW4+QKl JlfGWVC2wvjtgSj+S/DXSz4HsV3TeMNWNhioZFVRFFNRmrtmvsv3iZAOdrN166STn+W/ qJJA3awV1HLlp46QQM1FEEJk6uqUyOsBYPznwv3QMbpr0USiz869rjzieOMMV88le+Ks sleLm/1t2lfMNDzyTyjCwOJ51qkhr70Ug+vrkX+i61hghvKZCasO3iY8e3PxdmYhTxtP 4u8A== X-Received: by 10.180.205.139 with SMTP id lg11mr6050508wic.62.1434715957467; Fri, 19 Jun 2015 05:12:37 -0700 (PDT) Received: from [192.168.0.8] (97e3cdda.skybroadband.com.

The notebook (or perhaps toploop_js to be more specific?) predicate
does seem like the right way to do things, despite the OASIS tooling
issue.  We may be able to do something in the iocaml build loop to
do a separate query for the new predicate based on the results from a
search for toploop.

I'm just wondering how likely it is that a package will want to have
multiple toploop printers (a dumb HTML one would just be the normal
toploop wrapped in `
`, or a fancy IOCamlJS interactive one).

Hi,

is there a minimal invasive way to refer to Unix.tm inside of a
library which should also be usable on mirage? I know that mirage
provides the same type via CLOCK.tm, but I also do not want to depend
on mirage just for the type.

I provided sensible default values for validity times of a X.509
certificate using Unix.tm/gmtime/time -- all of which are also
available in the mirage CLOCK module type. Is there a way that the
X.509 library uses these symbols from the Unix module, and mirage
takes care that they're available (trivial in the non-xen case, in the
xen case I believe the OCaml runtime from mirage-xen-ocaml needs to be
modified slightly!?)?

I cannot come up with clean solutions off the top of my head atm, but
I'd be glad if there is a simple solution. Maybe a lightweight
calendar/date library providing functionality such as Unix.tm and
Unix.gmtime would be sufficient? (ASN.1 combinators already provide
some basics (float -> t, t -> float where t is similar to Unix.tm):
https://github.com/mirleft/ocaml-asn1-combinators/blob/master/src/asn_time.mli


Ideas? Thoughts?

Finally got around to writing this up:

I'd be particularly interested to hear about suggestions for avoiding
the React GC issues.

Finally got around to writing this up:

I'd be particularly interested to hear about suggestions for avoiding
the React GC issues.

Very nice write up! I was eagerly waiting for it; especially the 
tyxml/react part, since we didn't got much feedback on that. I'm rather 
happy to see that you used it and enjoyed the convenient combinators and 
the additional type safety. I agree that the documentation is less than 
satisfactory, I have yet to find a nice way to document such complex 
typing.
I'm surprised you understand it by *reading the code* given the 
functorization and the typing. :D

Apart from the typical react issues, what was your feeling on the tyxml 
react things, from a GUI building aspect ?

For the GC issues, Lwt_react[1] helps a bit, in particular E.keep and 
S.keep. It basically implements your "global sink" idea. Doesn't solve 
the space leaks in javascript, though. Lwt_react in general is a very 
nice improvement over React when used in conjunction with Lwt.

You didn't seem to use Lwt_js_events (or just didn't talked about it) in 
jsoo, is there a reason ?

Otherwise, the contribution of the indexedDB api to jsoo's api would be 
very welcome. ;)
The bigstring and bin_prot primitives have been implemented in js now 
(part of hhugo's effort to make Async work on jsoo), so you shouldn't 
need them any more.

A lightweight time library would be useful.  The issue with the current
CLOCK interface is that it defines a record type within a module type,
which is a little pointless -- it should be defined somewhere else such
as a library.

Two of Daniel's library's may help here:
- Mtime defines monotonic time (and maps it to POSIX/Js and could easily
  also be mapped to Xen PV)
- Bos defines OS interactions, such as seconds-since-1970:
  http://erratique.ch/software/bos/doc/Bos.OS.Time.html

The missing one here is something that breaks down the time into
something consumable by a calendar library, and ideally not specifically
tied to Unix.tm (which requires all the fields to be filled in, often
with weird offsets in some of the members).

A lightweight time library would be useful.  The issue with the current
CLOCK interface is that it defines a record type within a module type,
which is a little pointless -- it should be defined somewhere else such
as a library.

Two of Daniel's library's may help here:
- Mtime defines monotonic time (and maps it to POSIX/Js and could easily
  also be mapped to Xen PV)
- Bos defines OS interactions, such as seconds-since-1970:
  http://erratique.ch/software/bos/doc/Bos.OS.Time.html

The missing one here is something that breaks down the time into
something consumable by a calendar library, and ideally not specifically
tied to Unix.tm (which requires all the fields to be filled in, often
with weird offsets in some of the members).

Yeah, it's really nice! I think it just needs a little introduction
(maybe not much more than is in the blog post).

The only other (very minor) problems I had were:

1. Wanting to refer back to an element in a callback, for animations
or form values. There is some code like this:

    let item_ref = ref None in
    let callback ev = ... (use !item_ref) ... in
    let item = a ~a:[a_onclick callback] [...] in
    item_ref := Some item;

2. Some workarounds were needed for MSIE. e.g.

  https://github.com/talex5/cuekeeper/blob/90a12e71834ae10416e0ec86ce15408ec25d33e6/js/ck_template.ml#L27

Yes, but the global sink is only useful if unused handlers get freed.
Otherwise, it just stops things getting GC'd at all.

Handling events seemed simple enough with a_onclick attributes. I only
used Lwt_js_events for the "async" method. Would it have helped?

The problem here is I only implemented the bits I used. But if anyone
wants to take it forward the skeleton is here:

https://github.com/talex5/cuekeeper/blob/master/js/indexedDB.mli

BTW, that reminds me: there's a typo in the HTML storage (dom_html.ml):

  method keynewValue : js_string t opt readonly_prop

(should be just "newValue").

Really nice!  I'm curious about whether this is a good time to pull out
the IndexedDB bindings into their own mini-library?  They would be useful
to provide a minimal Irmin backend without the rest of the CueKeeper code
to act as a guide.  Spiros (CCed) may be interested in this for a project
he's working on.

These GC issues seem to be as old as FRP itself. A slightly higher-level
question: do you have any sense as to how well this model could be mapped
onto React.js and its virtual DOM model?
http://facebook.github.io/react/

There seem to be a growing set of UI components that only use one-way data
flow and hence avoid the trap of leaking signals that seem to be quite
common when using  FRP.

Really nice!  I'm curious about whether this is a good time to pull out
the IndexedDB bindings into their own mini-library?  They would be useful
to provide a minimal Irmin backend without the rest of the CueKeeper code
to act as a guide.  Spiros (CCed) may be interested in this for a project
he's working on.

These GC issues seem to be as old as FRP itself. A slightly higher-level
question: do you have any sense as to how well this model could be mapped
onto React.js and its virtual DOM model?
http://facebook.github.io/react/

There seem to be a growing set of UI components that only use one-way data
flow and hence avoid the trap of leaking signals that seem to be quite
common when using  FRP.

This is the typical example where you want to use Lwt_js_events, which 
avoids the recursion (and the reference)

     let item = a [ ... ] in
     let dom_item = Tyxml_js.To_dom.of_a item in
     Lwt.async (fun () -> Lwt_js_events.clicks dom_item (fun _ev 
_handler -> .... use dom_item/item ...))

We could implement Lwt_js_event (and a mutation module similar to 
Eliom_content.Manip[2]) directly on Tyxml_js's nodes, but it's not done 
right now.
And it would need more functors...

Well, here is the implementation of keep:

     let keeped = ref []
     let keep e = keeped := map ignore e :: !keeped

(that's React's ignore)

So you should be able to have several "keepers" like that, and the 
lifetime of signals would be the lifetime of the keeper.

It avoids recursion issues (see earlier) and occasionally offer very 
interesting control over the buffering and the sequentiality of events.
You can also do complex stuff very easily, like receive event A, wait 
for event B, then on receiving B, start waiting for A again.
That's quite useful sometimes.

Our next Document Day is this Wednesday.  This month, we'd like to
catch up with the latest advances in the project.  Some topics to
address include:
- Mirage OS: we need current information about Mirage, with links to
key pages on the Mirage wiki
- XAPI: The latest docs from the XenServer crew need to be referenced
from our wiki
- Unikernels: Beyond Mirage OS, lots of other Unikernels leverage Xen
Project; we need them properly linked in to our wiki
- Raisin: the new effort has a new wiki page which needs review
- anything else which need to be brought up to date

All the information you need to participate in Document Day is here:

http://wiki.xenproject.org/wiki/Xen_Document_Days

Also take a look at the current TODO list to see other items which
need attention:

http://wiki.xenproject.org/wiki/Xen_Document_Days/TODO

Please think about how you can help out.  If you haven't requested
to be made a Wiki editor, save time and do it now so you are ready to
go on Document Day.  Just fill out the form below:

We hope to see you Wednesday in #xendocs!

TL;DR Test the MirageOS/TLS stuff now!

Rest of message follows :)

Hi folks,

As some of you may have noticed, we're planning a short series of blog posts about the recent work on TLS integration for MirageOS [1].

We've released a number of packages into mainstream OPAM so this work is already available to everyone.  I previously asked folks to try out the stack and give feedback [2] and since packages are out, I hope we see more live deployments. 

If you've already tried out the stack, or have it running live, please do share!  If you've been thinking about it, then now is a great time to get involved (you might find the draft blog post on mirage-seal useful to look at.  The PR is at [3] but do read the thread first).

Thanks!
Amir

PS We also added a page on breaking changes, which you might like to be aware of [4].

Yay!

- https://mirage.io is running the Xen version (and will be running the released packages below very soon). 

- https://realwordocaml.org is running Unix tlstunnel.  This is a really easy way to use a good portion of the stack without having to use Xen.  If you have stunnel or stud in use somewhere, then replacing it with the tlstunnel binary and giving positive/negative reports would be appreciated.

I have now settled down on an interface for Ptime and would welcome feedback about it. Here's the documentation:


http://erratique.ch/software/ptime/doc/Ptime

A few notes 

* Some of the names may seem verbose or long-winded. This is out of frustration of reading code that is confusingly quiet about the units and time scales it considers. I think that whenever time is handled it's better to be explicit so that it's easier to understand if functions are being fed with the right data.

* At the moment Ptime doesn't provide a way to access the current POSIX timestamp/tz_offset on your OS. This will be provided later via a Ptime_os module with this [1] interface through platform dependent subpackages. The Ptime module itself will remain free from any interaction with the OS.

* I would be glad like to get feedback on the way the library decides to handle leap seconds (see the basics section). The design rationale here is that by not having a leap second table we do handle very few edge cases in a suboptimal fashion and we cannot measure the number of SI seconds that occur between two timestamps. These cases are precisely specified and force you to program with that knowledge, by mostly doing nothing about it... If the library did include a leap seconds table we could handle these cases, however the correctness of the implementation would be challenged every six month by the potential addition or subtraction of a leap second (e.g. one is being added on the 1rst of july). Effectively this means that correctness depends on conditions external to the software itself and regaining it requires an update of the module and its dependent. Since in practice software tends to run for very long time without being updated I prefer the idea that the API impleme
 ntation 
remains correct at all points in time. Note also that the way this is handled is equivalent to what gmtime/mktime do.

* Regarding the preceeding point I'm tempted to remove the `{add,sub,diff}_posix_s` as it would reduce the problematic cases. OTOH if I remove them I'm almost sure that people are then going to simply use `to_posix_s` and add floats and come back with `of_posix_s`. At least having the functions in the API we can warn users in the docs that they are very likely trying to do something wrong. 

* Supporting POSIX timestamps representing point in time in BCE means that we get option results on to_date_utc_time (the well-sourced calendar calculation i use only work until -4800 BCE, I'll see if I can find another well-sourced alternative) and to_rfc3339 (which cannot represent BCE dates at all). We could require timestamps to start at 0001-01-01 00:00:00 UTC, while this would remove the options from these two functions, it would introduce one in of_posix_s (in which we could also put the nan case rather than raise invalid_argument). Also as mentioned in [2] the gmtime function of other major platforms does actually handle these kind of time stamps so it may be better to support them aswell. 

* The package depends on rresult at the moment but it is planned to drop that dependency once Pervasives.result is in. 

Best,

Daniel

Hi,

> - https://mirage.io is running the Xen version (and will be running the released packages below very soon). 

I've just updated the live website to use the new software stack, and to be automatically updated on every merge of mirage-www. Please report any issues to the bug-tracker (if possible with a PCAP file to help us understand what happen). 

Best,
Thomas

> 
> - https://realwordocaml.org is running Unix tlstunnel.  This is a really easy way to use a good portion of the stack without having to use Xen.  If you have stunnel or stud in use somewhere, then replacing it with the tlstunnel binary and giving positive/negative reports would be appreciated.

Hi,

> - https://mirage.io is running the Xen version (and will be running the released packages below very soon). 

I've just updated the live website to use the new software stack, and to be automatically updated on every merge of mirage-www. Please report any issues to the bug-tracker (if possible with a PCAP file to help us understand what happen). 

Best,
Thomas

> 
> - https://realwordocaml.org is running Unix tlstunnel.  This is a really easy way to use a good portion of the stack without having to use Xen.  If you have stunnel or stud in use somewhere, then replacing it with the tlstunnel binary and giving positive/negative reports would be appreciated.

Why not delay the connection until the map signal is ref'd? Othe=
rwise

(as you note below) it will leak.

up in the update step but since it has a ref count of 0 we don't update=
 it and remove it from x's dependents and decrease `x`'s ref count =

 a node's dependents array, except for the ability to specify that you =
would like to retain/release or subscribe/unsubscribe a node at the leaves)=

Why not delay the connection until the map signal is ref'd? Othe=
rwise

(as you note below) it will leak.

up in the update step but since it has a ref count of 0 we don't update=
 it and remove it from x's dependents and decrease `x`'s ref count =

 a node's dependents array, except for the ability to specify that you =
would like to retain/release or subscribe/unsubscribe a node at the leaves)=

This one came out of the blue to me, but I noticed it in a tweet from Ranjit Jhala. MPI folk have combined refinement types and (concurrent) separation logic in order to verify properties about Lwt.

Their test case? Dave Scott's OCaml FAT implementation that we use in MirageOS. Spoiler: they found bugs :-)

I'm still reading through it but thought I'd get it out to the list early...

It look that I've been bitten by partial applications ... the dispatch =
function were memoizing *all* the web-pages on every requests, ie. =
parsing all the templates, converting mardown to HTML, creating the atom =
feed, etc... for every element loaded (the page itself, the JS scripts, =
the CSS, the images, etc). This stupid mistake was introduced when I've =
refactored the website last week and is now fixed by [1]. I'm really =
surprised (and almost quite happy) to see how "well" the server =
responded to the big CPU load.

The fix is now live and the website starts to be much more responsive =
again, and the number of page served per second[2] is increasing =
steadily.

Best,
Thomas

Yup, just noticed too. Thanks =
for taking a look. 

Will have to look into this and figure out what's up. I think =
Magnus and Thomas are aware of retransmissions. 

It look that I've been bitten by partial =
applications ... the dispatch function were memoizing *all* the =
web-pages on every requests, ie. parsing all the templates, converting =
mardown to HTML, creating the atom feed, etc... for every element loaded =
(the page itself, the JS scripts, the CSS, the images, etc). This stupid =

how "well" the server responded to the big CPU load.

The fix is now live and the website starts to be =
much more responsive again, and the number of page served per second[2] =
is increasing steadily.

Best,
Thomas
