On linux, you can run ctag= s -x and postprocess the file to append the line number to the file name instead of having i as a separate field. That way, you can locate the symbol in the tags file, and right-click on the file:linenumber<= /a>.

Also, on linux, we have acme-lsp, which in pr= inciple works with any LSP server. I have tested it with go and C/C++.

Hello 9fans,

I've just recently started using the acme editor and am really enjoying
it, and trying to get the hang of the "acme way" of doi= ng things. One
bit of functionality that I'm familiar with from other editors is the
ability to easily look up a function or symbol definition within a
codebase. In Emacs and vi, this is done by generating tags files (etags
or ctags), which those editors can parse and allow you to easily jump to
a definition of the symbol under the point/cursor.

What's the preferred method or workflow for achieving this in acme? I
have tried passing a selected symbol to 'g -n' in the win= dow's tag,
using the Mouse-2 + Mouse-1 chord. That gets me part of the way there
but isn't effective if the file where the symbol is defined happens to
be in another directory. I feel like I'm missing something.
Many thanks!

- Ben

Mine is here: http://9p.io/sources/contrib/anothy/src/ctags/ It is a pretty straight-forward port, just adding an output type suitable for acme (file:n). About a year ago (I think?) someone told me that they did an updated port, but I can't find the reference quickly. Personally, I find ctags (and similar tools) useful only in extreme circumstances, and otherwise rely only on acme's built-in matching and a few scripts similar to what's been posted here. ------------------------------------------ 9fans: 9fans Permalink: https://9fans.topicbox.com/groups/9fans/Tf8ceac12df9da674-M32237c6cd7f205230d8b175a Delivery options: https://9fans.topicbox.com/groups/9fans/subscription From bounce.mM5630d14b408680d32b257869.rf428fd94-eb83-11e9-92f5-7ab8f5b1d025@9fans.bounce.topicbox.com Fri Aug 20 23:38:27 2021 Return-Path: Received: from tb-ob20.topicbox.com (tb-ob20.topicbox.com [173.228.157.66]) by mx.sdf.org (8.15.2/8.14.5) with ESMTPS id 17KNcRZ7012402 (using TLSv1.2 with cipher ECDHE-RSA-AES256-GCM-SHA384 (256 bits) verified NO) for ;

I've spent some time bikeshedding this sickly program, and attached is the sickly result. It does neat things like `seq -w 003` printing out 001, 002, 003. It probably shouldn't do that, though. It also doesn't use exponential notation to print out numbers. This allows seq to not be limited from -999999 to 999999. Even still, the result doesn't feel quite right. Implementing a floating point number parser in seq is weird. Invalid number combinations cause it to crash. The following does not print out 0.3 in either implementation: seq 0.1 0.1 0.3 The only way to correctly print out decimals is by nesting seq: for(i in `{seq 0 9}) for(j in `{seq -w 0 9}) echo $i.$j Therefore, I propose replacing floating point with integers. If we're lucky, seq can count decimals using integers. We can also implement hexadecimal counting.

The best I can tell is that the parser for lynx didn't understand the authn part of the URI. I think libhttpd doesn't have the same problem--it just returns a bad uri, which is better than leaking. I'm looking at /sys/src/libhttpd/parsereq.c:/^parseuri . /sys/src/libhttpd/parse.c parses the mime header, so it's not an issue with requests that are sent with the authorization that way. From httpd(2): BUGS This is a rough implementation and many details are going to change. Webfs(4) looks to handle things properly in parsing ( /sys/src/cmd/webfs/url.c ), but would still generate a URI that libhttpd couldn't handle: /sys/src/cmd/webfs/url.c:^/Ufmt . Questions: if my analysis is correct, should parseuri be made to parse authuser and authpass? Or is libhttpd not used as much and other software is preferred?

I've also added a Readme for the ppc kernel. I gleaned the Readme and some code from the Plan 9 kernel found on github; I assume it was updated after 9front had forked. I made some minor edits to Readme, but otherwise I left the code received as-is (namely, ppc/^(trap.c l.s devce.c) ). I did not see any manual page for devce.

If we live on other OSs than plan9, we cannot do anything other than those device drivers. However, if we consider it more deep, we don't need not so much kinds of running terminals. We need only one cpu/auth/file server machine and many of drawterms, or as Russ is doing plan9port. If we consider it like this, we should discuss what kinds of computer work we want.

I did port a somewhat outdated C library: https://github.com/echoline/fann it isn't nearly as customizable as tensorflow though. I always really liked the "XCPU" and drawterm type ideas of using other OSes for their existing strengths along with Plan 9. maybe drawterm could have a GPU device driver or something... that being said I have sometimes found it ends up surprisingly easier doing it all on Plan 9... - Eli On Sat, Aug 21, 2021 at 7:48 PM wrote: > > I have ended up using 9front more and more, obviously. 9front was > > started specifically to address the fact that Plan 9 from Bell Labs > > didn't run on most computers... > > me, too. > > 9front have many kinds of device drivers.

That's also something I thought about a few times already: drawterm with GPU support. The only issue I see is, for realtime applications like games the draw times would be network bound and thus pretty slow. It would work for heavy GPU applications where almost no draw calls will exist (no textures, very low poly meshes, ...), but for heavier stuff we'd need to address that. That's the benefit of a native driver: you could calculate the server side (heavy CPU calculations) on a cpu server, the client/frontend side (including draw calls) on a terminal and the pure graphics on the GPU. I'd still give the drawterm GPU a shot. Maybe I can set drawterm up for compilation on my work PC (two GTX 1080Ti) and try figuring out how to do all that stuff. However, I've never done graphics applications on windows or somewhere else that uses OpenGL or DirectX (I'd try OpenGL because portability), only written shaders so far. I'll surely need some time (which is always rare as a game developer). Btw I don't know the exact specifications for GPU usage for neural networks. I assume it's all compute shaders? Maybe it's even a kinda blackbox, put stuff in (draw call), read things out. I assume this can work perfectly fine for draw times, depending on the data. sirjofri ------------------------------------------ 9fans: 9fans Permalink:

instead of 6 so fw doesn't > spit us an ADVANCED_SYSASSERT, it was reading 2 more > extra bytes. apparently those 2 extra bytes were put to > the first 2 bytes of our buffer, so we got to skip that. some more thoughts on this, i think as 0x15*2 is not multiple of 8, fw rounds the offset to 0x14*2. i have touched to code to read data from 0x14*2 then ignore the first 2 bytes, just so it's not confusing. if this causes mac to be read wrong again, report. also, some more changes: 1. set the fwname at iwlpci, just to align the behavior with 8000+. this is a cosmetic change. 2. i have discovered that on device boot/reset/shutdown functions, our driver slept way much more than it should. the reason for that is, driver used the function delay() on places where it needs to use microdelay() instead. i have modified the code to use microdelay(). wpi likely needs similar changes too. i hope that this does not break the code. 3. zzz a bit more on tx/rx scheduler shutdowns and niclock. 4. openbsd's iwm and linux apparently does not check if ownership was obtained anymore in their handover functions. instead they just loop until the hw is ready. aligned the behavior. see linux commit: 289e5501c3141191dd830957f1d764d3dc14a54f 5. don't take antenna masks from nvm. it's apparently empty in some cards from 7k family. we will rely on what the fw file gives us. 6. when the calibration is completed, wakeup the proc that runs postboot. otherwise that thing sleeps for like 2 whole seconds even if calibration completed earlier. i honestly don't think any of these changes will fix 7260 not being able to get calibration results, but i don't see anything wrong at all in postboot7000 at this point. i will just hope these changes somehow make it get calibration results.

The ability to leverage GPU resources across CPU servers for computation purposes would be of great benefit to the platform, and working out a driver interface by starting the process remotely via drawterm seems like a sensible step in that direction.

I just lack lots of knowledge about this, the gist was to write shader (code or compiled?) into some files, also write image data and mesh data to other files, abd reading results from other files. But as I said, I lack lots of knowledge about how GPUs work and never wrote any OpenGL code myself, only shader code. It always seemed like it's hundreds of hundreds of lines of code to draw a triangle (which is the basic hello world program). sirjofri 22.08.2021 12:04:41 Frank D.

There's virtio_gpu, which I assume is less hairy and better-documented than real hardware. I think it's graphics-purpose-only. Maybe you'd be better-off just supporting cards that *only* do ML/NN acceleration? There's open-source ones. Also: > people have discussed that for years They have? I mean I might have seen occasionally someone vaguely going "some sort of GPU support would be cool to have". That isn't discussion. ------------------------------------------ 9fans: 9fans Permalink: https://9fans.topicbox.com/groups/9fans/Tad29bfc223dc4fbe-M3cda662328b544acbd9fd894 Delivery options: https://9fans.topicbox.com/groups/9fans/subscription From bounce.mM2811fbdfd8c6710bf58ff059.rf428fd94-eb83-11e9-92f5-7ab8f5b1d025@9fans.bounce.topicbox.com Sun Aug 22 12:33:07 2021 Return-Path: Received: from tb-ob0.topicbox.com (tb-ob0.topicbox.com [64.147.108.117]) by mx.sdf.org (8.15.2/8.14.5) with ESMTPS id 17MCX68W006131 (using TLSv1.2 with cipher ECDHE-RSA-AES256-GCM-SHA384 (256 bits) verified NO) for ;

I've even heard of someone actually making GPU stuff work on plan 9. I&= #39;ve
only heard from their partner, who made a cute glenda thing on a piece of <= br /> cloth. I chatted with her a little and told her she should encourage her partner for some discussion about this in our channels. It looked like
it's some academic work, but I don't know any details about it.

Worst case, someone already has a proper and good GPU implementation for Plan 9 and nobody knows about it.

sirjofri

Btw if the said person reads this: it would be nice to learn some
details.

I'm not sure where I saw that or thought that... that was more what I was thinking, though. On Sun, Aug 22, 2021 at 6:46 AM Paul Lalonde wrote: > > I'd love to see GPU support for Plan9. This discussion falls right into my professional capacity. I'll say that people generally *grossly* underestimate the complexity of a modern GPU and of its supporting software stack. The GPU driver is effectively a second operating system with shared memory and DMA interfaces to the host. Even bringing up a modern GPU for just compute tasks is a very large endeavour. > > That being said, if you want real hardware support, the best place to start is currently AMD's open-source stack. Ignoring the Vulkan bit, understanding their platform abstraction layer (PAL) and shader ISA (https://developer.amd.com/wp-content/resources/Vega_Shader_ISA_28July2017.pdf) is the base. The lower hardware levels are reasonably well-described in linux's libdrm and its AMD support in amdgpu. > > Opinions on how to bring this to Plan9? I don't really have any - it's a huge pile of work with minimal benefit. If you're looking for lightweight graphics, WebGL is a doable path, and almost certainly the right way to experiment with Plan9-like interfaces to graphics hardware. > > Paul > > > > On Sun, Aug 22, 2021 at 5:30 AM sirjofri wrote: >> >> >> 22.08.2021 14:10:20 Stuart Morrow : >> > Also: >> >> people have discussed that for years >> > >> > They have?

Eg for the windows version you can just write the software that uses the GPU driver. All programming effort will just be writing a graphics implementation and a proper 9p interface. Basically just a driver bridge between 9p and OpenGL for example. sirjofri 22.08.2021 15:44:45 Paul Lalonde : > I'd love to see  GPU support for Plan9.  This discussion falls right > into my professional capacity.  I'll say that people generally > *grossly* underestimate the complexity of a modern GPU and of its > supporting software stack.  The GPU driver is effectively a second > operating system with shared memory and DMA interfaces to the host.  > Even bringing up a modern GPU for just compute tasks is a very large > endeavour. > > That being said, if you want real hardware support, the best place to > start is currently AMD's open-source stack.  Ignoring the Vulkan bit, > understanding their platform abstraction layer (PAL) and shader ISA > (https://developer.amd.com/wp-content/resources/Vega_Shader_ISA_28July2017.pdf) > is the base.  The lower hardware levels are reasonably > well-described in linux's libdrm and its AMD support in amdgpu. > > Opinions on how to bring this to Plan9?  I don't really have any - it's > a huge pile of work with minimal benefit.  If you're looking for > lightweight graphics, WebGL is a doable path, and almost certainly the > right way to experiment with Plan9-like interfaces to graphics > hardware. > > Paul > > > > On Sun, Aug 22, 2021 at 5:30 AM sirjofri > wrote: >> >> 22.08.2021 14:10:20 Stuart Morrow : >>> Also: >>>> people have discussed that for years >>> >>> They have?  I mean I might have seen occasionally someone vaguely >>> going "some sort of GPU support would be cool to have".  That isn't >>> discussion. >> >> I've even heard of someone actually making GPU stuff work on plan 9. >> I've >> only heard from their partner, who made a cute glenda thing on a piece >> of >> cloth.

I've even heard of someone actually making GPU stuff work on plan 9. I&= #39;ve
only heard from their partner, who made a cute glenda thing on a piece of <= br class=3D"" /> cloth. I chatted with her a little and told her she should encourage her partner for some discussion about this in our channels. It looked like
it's some academic work, but I don't know any details about it.

Worst case, someone already has a proper and good GPU implementation for Plan 9 and nobody knows about it.

sirjofri

Btw if the said person reads this: it would be nice to learn some
details.

I've even heard of someone actually making GPU stuff work on plan 9. I&= #39;ve
only heard from their partner, who made a cute glenda thing on a piece of <= br /> cloth. I chatted with her a little and told her she should encourage her partner for some discussion about this in our channels. It looked like
it's some academic work, but I don't know any details about it.

Worst case, someone already has a proper and good GPU implementation for Plan 9 and nobody knows about it.

sirjofri

Btw if the said person reads this: it would be nice to learn some
details.

It seems like the interesting part of GPUs is the general purpose computation. Writing an interface for pure computation seems like the way to go. Hardware rendering is a restricted case of software rendering; it seems like it would be better to write code that could do software rendering, and run it on the general purpose compute engine of the GPU. The same goes for basically everything else you may want to do with a GPU. It also seems like it may be both a more useful and more long-lived tool. Spitballing a while ago on the grid, I came up with something that looked a bit like a batch job interface, with a heirarchy that looks something like this: /dev/compute new $func/new $func/$job/data $func/$job/result which you could use from a script like so: #!/bin/rc # example: # # runs the neural net for finding cats, # which is compiled using some sort of # compiler backend that generates spirv, <[3=1] <>/dev/compute/new{ # upload the code which can then # be run by the compute engine; # statically allocating resources # can simplify the driver. # # protocol would look something # like: # "config param\n" # "config param\n" # "code\n" # # EOF filtdir=/dev/compute/`{sed 1q} echo alloc 8g echo code cat /bin/spir/catfinder # then launch a job, sending it # the arguments over the data # channel. # # it's up to the submitter and # the compute job to agreee on a # format; in this case, a single # uncompressed plan9 image is # written, and the result file # could contain a single string: # 'cat', 'not cat', or 'rifle' <>$dir/new{ jobdir=/dev/compute/`{sed 1q} jpg -9 $i >$jobdir/data cat $jobdir/result >[3] } } Prototyping something like this as a 9p server on unix would be interesting. So would providing this kind of cpu interface in software. Vmx could be extended with device passthrough if you want to fit the entire thing on one box, and then you may be able to find someone with a bunch of time on their hands to write a basic driver... maybe. Hooking this up to devdraw would probably be interesting for doing "hardware" rendering, though latency may be an issue if it's not implemetned as a local '#' device. Anyways, this is fun to consider, but I've got other more quotidian tools to work on before I even think about thinking about this more :) ------------------------------------------ 9fans: 9fans Permalink: https://9fans.topicbox.com/groups/9fans/Tad29bfc223dc4fbe-Mc5753788883d2ed17e4acdbd Delivery options: https://9fans.topicbox.com/groups/9fans/subscription From bounce.mM669861f673e387c2799da01b.rf428fd94-eb83-11e9-92f5-7ab8f5b1d025@9fans.bounce.topicbox.com Sun Aug 22 16:54:16 2021 Return-Path: Received: from tb-ob1.topicbox.com (tb-ob1.topicbox.com [64.147.108.173]) by mx.sdf.org (8.15.2/8.14.5) with ESMTPS id 17MGsFH6016117 (using TLSv1.2 with cipher ECDHE-RSA-AES256-GCM-SHA384 (256 bits) verified NO) for ;

This changes git/diff and git/import so that things will generally work even when assembling diffs by hand: 1. git/import becomes slightly more lax: ^diff ... ^--- ... will both be detected as the start of a patch. 2. git/diff produces the same format of diff as git/export, starting with paths: --- a/path/to/file +++ b/path/to/file which means that the 'ape/patch -p1' used within git/import will just work. So with this, if you send an email to the mailing list, write up a committable description, and append the output of git/diff to the end of the email, git/import should just work. [this patch was send through the mailing list using the above procedure, and will be committed with git/import to verify that it works as advertised] diff 8c228a123fa0c6062570964011854302bbf57242 uncommitted --- a/sys/src/cmd/git/diff +++ b/sys/src/cmd/git/diff @@ -26,12 +26,16 @@ git/query -c $commit HEAD | subst '^..' } +mntgen /mnt/scratch +bind $branch/tree/ /mnt/scratch/a +bind . /mnt/scratch/b +echo diff `{git/query $commit} uncommitted for(f in `$nl{lsdirty | sort | uniq}){ - orig=$branch/tree/$f - if(! test -f $orig) + cd /mnt/scratch + if(! test -f a/$f) orig=/dev/null - if(! test -f $f) + if(! test -f b/$f) f=/dev/null - diff -u $orig $f + diff -u a/$f b/$f } exit '' --- a/sys/src/cmd/git/import +++ b/sys/src/cmd/git/import @@ -45,7 +45,7 @@ state="body" next } - (state=="headers" || state=="body") && (/^diff/ || /^---[ ]*$/){ + (state=="headers" || state=="body") && (/^diff / || /^--- /){ state="diff" } state=="body" { ------------------------------------------ 9fans: 9fans Permalink: https://9fans.topicbox.com/groups/9fans/T403f90e3b0509704-Md1cc4902bb399c16511e2f9b Delivery options: https://9fans.topicbox.com/groups/9fans/subscription From bounce.mM300dfe7499e5b62ca9db9bbf.rf428fd94-eb83-11e9-92f5-7ab8f5b1d025@9fans.bounce.topicbox.com Sun Aug 22 17:23:27 2021 Return-Path: Received: from tb-ob20.topicbox.com (tb-ob20.topicbox.com [173.228.157.66]) by mx.sdf.org (8.15.2/8.14.5) with ESMTPS id 17MHNRBZ026701 (using TLSv1.2 with cipher ECDHE-RSA-AES256-GCM-SHA384 (256 bits) verified NO) for ;

The same goes for > basically everything else you may want to do > with a GPU. Basically do software rendering on the GPU? Well, it's totally possible. Even Nanite (the new system in Unreal Engine 5) has its own rasterizer and I believe even its own base pass. Also Lumen does software rendering for global illumination. But for serious 3d AAA stuff we'd have to consider: Lumen is for next-gen GPUs and Nanite for newer GPUs. We'll never reach their quality in realtime if we don't use the GPU features (built-in rasterizer, ...) to have enough free power for crazy software calculation. On the other hand, getting _any_ GPU computation running on Plan 9 would be great, even if it's just compatible pure-CPU implementation (aka gpufs without a GPU). > Spitballing a while ago on the grid, I came > up with something that looked a bit like a > batch job interface, with a heirarchy that > looks something like this: > >         /dev/compute >                 new >                 $func/new >                 $func/$job/data >                 $func/$job/result I like that /dev/compute approach, but may I suggest putting it below another directory /dev/gpu/compute so we have the ability to add /dev/gpu/{vertex,geometry,fragment,tessellation,pixel} later? I haven't looked at your sample script in more detail, but on the first glance it seems solid. > Prototyping something like this as a 9p server > on unix would be interesting. So would providing > this kind of cpu interface in software. This is also a great idea, instead of tweaking drawterm. I don't have a linux machine with a GPU (I'm full 9front and only windows for work), but I guess if this prototype uses OpenGL (or alt) it could also work with software GPU emulation. I'd really like to try something like that, but writing filesystems is (still, sadly) new to me and I also don't have much time, being a full-time game developer. If someone else wants to try it please make development open source so we can provide patches, and I'm also happy to at least test things. > Hooking this up to devdraw would probably be > interesting for doing "hardware" rendering, though > latency may be an issue if it's not implemetned as > a local '#' device. I'm not sure about the latency (I would just try it once it's done), but can't we use the hwdraw stub function for interfacing with this? I also doubt we'll draw many complex shaders for /dev/draw. sirjofri ------------------------------------------ 9fans: 9fans Permalink: https://9fans.topicbox.com/groups/9fans/Tad29bfc223dc4fbe-Mf5ef60c88b77f937e3cd7c38 Delivery options: https://9fans.topicbox.com/groups/9fans/subscription From bounce.mM9436d5323abdd3522e9996aa.rf428fd94-eb83-11e9-92f5-7ab8f5b1d025@9fans.bounce.topicbox.com Sun Aug 22 18:33:49 2021 Return-Path: Received: from tb-ob21.topicbox.com (tb-ob21.topicbox.com [173.228.157.67]) by mx.sdf.org (8.15.2/8.14.5) with ESMTPS id 17MIXmnC029725 (using TLSv1.2 with cipher ECDHE-RSA-AES256-GCM-SHA384 (256 bits) verified NO) for ;

Yes. Or software neural net evaluation on the GPU. Or software video decoding on the GPU. Or software image transforms on the GPU. Or software signal processing on the GPU. If there's an interface to be selected, it needs to be tractable to implement, *and* general purpose enough for everything that wants to use it. > Well, it's totally possible.

By the time any code is written, next-gen GPUs will be previous-gen GPUs. General compute is what any hardware you buy a few years from now will be doing -- and it's far more intersting in terms of what capabilities it allows. > I like that /dev/compute approach, but may I suggest putting it below > another directory /dev/gpu/compute so we have the ability to add > /dev/gpu/{vertex,geometry,fragment,tessellation,pixel} later? I think supporting those is a cost we should not pay. It's fundamentally solving a less general problem, and adds a lot of complexity for the potential of a small performance boost. We already have zero people sinking time into the slim interface; sinking time into a fatter interface seems like a bad idea. ------------------------------------------ 9fans: 9fans Permalink: https://9fans.topicbox.com/groups/9fans/Tad29bfc223dc4fbe-M9436d5323abdd3522e9996aa Delivery options: https://9fans.topicbox.com/groups/9fans/subscription From bounce.mM3c0e76a0b437dd9071c6f579.rf428fd94-eb83-11e9-92f5-7ab8f5b1d025@9fans.bounce.topicbox.com Sun Aug 22 18:58:06 2021 Return-Path: Received: from tb-ob0.topicbox.com (tb-ob0.topicbox.com [64.147.108.117]) by mx.sdf.org (8.15.2/8.14.5) with ESMTPS id 17MIw54g011054 (using TLSv1.2 with cipher ECDHE-RSA-AES256-GCM-SHA384 (256 bits) verified NO) for ;

I've even heard of someone actually making GPU stuff work on plan 9. I&= #39;ve
only heard from their partner, who made a cute glenda thing on a piece of <= br class=3D"" /> cloth. I chatted with her a little and told her she should encourage her partner for some discussion about this in our channels. It looked like
it's some academic work, but I don't know any details about it.

Worst case, someone already has a proper and good GPU implementation for Plan 9 and nobody knows about it.

sirjofri

Btw if the said person reads this: it would be nice to learn some
details.

I've even heard of someone actually making GPU stuff work on plan 9. I&= #39;ve
only heard from their partner, who made a cute glenda thing on a piece of <= br /> cloth. I chatted with her a little and told her she should encourage her partner for some discussion about this in our channels. It looked like
it's some academic work, but I don't know any details about it.

Worst case, someone already has a proper and good GPU implementation for Plan 9 and nobody knows about it.

sirjofri

Btw if the said person reads this: it would be nice to learn some
details.

I wrote a patch to add oauth support to upas/fs -- see attached: To use the patch, I followed this kind of clunky process: https://developers.google.com/identity/protocols/oauth2 I went to the 'credentials' section on the sidebar and I created a key for a 'desktop application'; Then I went to the 'oauth consent screen' and added my work email account as a 'test user'. I grabbed the keys, and on my unix box, went to the patched oauth: % cd $HOME/src/plan9port/src/cmd/oauth and generated a key using the full, browser based auth flow: % python httpd.py % ./oauth https://accounts.google.com https://mail.google.com/ $clientkey $clientsecret key proto=oauth issuer=https://accounts.google.com client_id=72... then edited the resulting output to include the appropriate attributes, adding the attributes in >>...<< for upas/fs: key proto=oauth >>service=imap server=imap.gmail.com user=ori@pingthings.io<< issuer=https://accounts.google.com client_id= token_type=Bearer exptime=1629662303 scope=... and then added that to factotum: echo key=... >/mnt/factotum/ctl With that, upas/fs just worked with my work email: upas/fs -f /imaps/imap.gmail.com/ori@pingthings.io Bugs: there are way too many steps. Unfortunately, the most annoying one is generating and adding an oauth client key/secret, and short of shipping a pregenerated one (is that a good idea?), I don't think there's a solution. Beyond that, 2 small bits of polish which I think we can do: - Adding a '-t' flag to oauth (the way auth/rsa does) to add type information to auth/oauth login would make it more convenient to use: the output could be stored directly rather than needing editing. - Adding a script that allows spawning a browser and http listener on unix (or redirecting thigns through to plan 9) would make it easier to drive the auth process from plan 9.

Don't forget to add type is text dst is oauth plumb to oauth to your plumber's rules file to create the oauth port. I have also added the authorization code flow to the factotum module (can be enabled by adding `flow=auth` to the key), but it requires the user to import the plan9port plumber into factotum's namespace. I am unsure what the best way to do this is. Plan9port provides import(4) which relies on SSH, but 9front does not provide an SSH server. -- Demetrius From bounce.mM0301c221a9c86a5cd726882d.rf428fd94-eb83-11e9-92f5-7ab8f5b1d025@9fans.bounce.topicbox.com Sun Aug 22 20:39:15 2021 Return-Path: Received: from tb-ob1.topicbox.com (tb-ob1.topicbox.com [64.147.108.173]) by mx.sdf.org (8.15.2/8.14.5) with ESMTPS id 17MKdFqm016866 (using TLSv1.2 with cipher ECDHE-RSA-AES256-GCM-SHA384 (256 bits) verified NO) for ;

Don't forget to add type is text dst is oauth plumb to oauth to your plumber's rules file to create the oauth port. I have also added the authorization code flow to the factotum module (can be enabled by adding `flow=auth` to the key), but it requires the user to import the plan9port plumber into factotum's namespace. I am unsure what the best way to do this is. Plan9port provides import(4) which relies on SSH, but 9front does not provide an SSH server. -- Demetrius ------------------------------------------ 9fans: 9fans Permalink: https://9fans.topicbox.com/groups/9fans/T6899bf3f0654295d-M0301c221a9c86a5cd726882d Delivery options: https://9fans.topicbox.com/groups/9fans/subscription From 9front-bounces@1ess.inri.net Sun Aug 22 20:42:44 2021 Return-Path: <9front-bounces@1ess.inri.net> Received: from 1ess.inri.net (1ess.inri.net [216.126.196.35]) by mx.sdf.org (8.15.2/8.14.5) with ESMTP id 17MKghpc017405 for ; Sun, 22 Aug 2021 20:42:43 GMT Received: from mimir.eigenstate.org ([206.124.132.107]) by 1ess; Sun Aug 22 16:38:23 -0400 2021 Received: from abbatoir.myfiosgateway.com (pool-74-108-56-225.nycmny.fios.verizon.net [74.108.56.225]) by mimir.eigenstate.org (OpenSMTPD) with ESMTPSA id a9245927 (TLSv1.2:ECDHE-RSA-AES256-SHA:256:NO); Sun, 22 Aug 2021 13:38:14 -0700 (PDT) Message-ID: To: 9fans@9fans.net CC: 9front@9front.org Date: Sun, 22 Aug 2021 16:38:13 -0400 From: ori@eigenstate.org In-Reply-To: MIME-Version: 1.0 Content-Type: text/plain; charset="US-ASCII" Content-Transfer-Encoding: 7bit List-ID: <9front.9front.org> List-Help: X-Glyph: ➈ X-Bullshit: core realtime-java module Subject: [9front] Re: [9fans] OAuth2 in factotum Reply-To: 9front@9front.org Precedence: bulk Quoth Demetrius Iatrakis : > > type is text > dst is oauth > plumb to oauth > > to your plumber's rules file to create the oauth port. Ah -- right. This is in the plan9port side, and it's used to send the oauth verification request to the browser. (iirc, it's not currently used for anything on the plan 9 side, though it wil be once we figure out how to glue together auth flows to either vmx or some unix browser) From bounce.mMbcaea13458be56f2909ea6c3.rf428fd94-eb83-11e9-92f5-7ab8f5b1d025@9fans.bounce.topicbox.com Sun Aug 22 20:43:27 2021 Return-Path: Received: from tb-ob20.topicbox.com (tb-ob20.topicbox.com [173.228.157.66]) by mx.sdf.org (8.15.2/8.14.5) with ESMTPS id 17MKhRgn018039 (using TLSv1.2 with cipher ECDHE-RSA-AES256-GCM-SHA384 (256 bits) verified NO) for ;

Ah -- right. This is in the plan9port side, and it's used to send the oauth verification request to the browser.

I wrote a patch to add oauth support to upas/fs -- see attached: To use the patch, I followed this kind of clunky process: https://developers.google.com/identity/protocols/oauth2 I went to the 'credentials' section on the sidebar and I created a key for a 'desktop application'; Then I went to the 'oauth consent screen' and added my work email account as a 'test user'. I grabbed the keys, and on my unix box, went to the patched oauth: % cd $HOME/src/plan9port/src/cmd/oauth and generated a key using the full, browser based auth flow: % python httpd.py % ./oauth https://accounts.google.com https://mail.google.com/ $clientkey $clientsecret key proto=oauth issuer=https://accounts.google.com client_id=72... then edited the resulting output to include the appropriate attributes, adding the attributes in >>...<< for upas/fs: key proto=oauth >>service=imap server=imap.gmail.com user=ori@pingthings.io<< issuer=https://accounts.google.com client_id= token_type=Bearer exptime=1629662303 scope=... and then added that to factotum: echo key=... >/mnt/factotum/ctl With that, upas/fs just worked with my work email: upas/fs -f /imaps/imap.gmail.com/ori@pingthings.io Bugs: there are way too many steps. Unfortunately, the most annoying one is generating and adding an oauth client key/secret, and short of shipping a pregenerated one (is that a good idea?), I don't think there's a solution. Beyond that, 2 small bits of polish which I think we can do: - Adding a '-t' flag to oauth (the way auth/rsa does) to add type information to auth/oauth login would make it more convenient to use: the output could be stored directly rather than needing editing. - Adding a script that allows spawning a browser and http listener on unix (or redirecting thigns through to plan 9) would make it easier to drive the auth process from plan 9.

I've even heard of someone actually making GPU stuff work on plan 9. I&= #39;ve
only heard from their partner, who made a cute glenda thing on a piece of <= br class=3D"" /> cloth. I chatted with her a little and told her she should encourage her partner for some discussion about this in our channels. It looked like
it's some academic work, but I don't know any details about it.

Worst case, someone already has a proper and good GPU implementation for Plan 9 and nobody knows about it.

sirjofri

Btw if the said person reads this: it would be nice to learn some
details.

The hundreds of cores are great for highly parallel calculation. In GLSL/HLSL I can write a program which is calculated for a very small set of pixels (usually 2x2 or 1x1). So if you have  a resolution of 10x10 the program is basically run 5x5=25 or 10x10=100 times in parallel. Boost the resolution to more real values like 1080p you see how the many cores benefit the whole calculation. This high parallelization can only really happen because most stuff is independent. For example, when raytracing each ray is (almost) independent of other rays. Still, the 2x2 matrix is often calculated dependently because for texturing (and mip mapping) you need the "distance" between two pixels in a fragment shader. This is why (for texturing) you may end up having slower programs and some waiting time between some threads, because sometimes you need the value of the neighbor thread and have to wait until it's calculated. Well, these are very language-specific details that are important for graphics, but apply similarly to other use cases. I can imagine that for neural networks you can just write the code for one node nad execute it 500 times for 500 nodes in parallel. Imagine having this beast on the CPU with just 4 cores... I hope this helps you understand how GPU cores ("shaders") work. Vulkan would indeed be interesting. Since we are only interested in the compute part it might even make our programs really small, the "hello world" part of drawing triangles would be the "client" side (writing a rasterizer, raymarcher, tracer, whatever). It could still be a lot lines of code, but maybe we still benefit from the 10% speedup. I still have to understand how all this "shader compilation" stuff works. In webgl it's like, "here's my code, make a shader from it, then I tell you it's a fragment shader". Shader compilation happens automatically. In UE shader compilation takes a long time, and I believe also in blender shaders are stored in a precompiled binaries. sirjofri 23.08.2021 06:13:53 Bakul Shah : > Don't high end GPUs have thousands of "cores"?

This changes git/diff and git/import so that things will generally work even when assembling diffs by hand: 1. git/import becomes slightly more lax: ^diff ... ^--- ... will both be detected as the start of a patch. 2. git/diff produces the same format of diff as git/export, starting with paths: --- a/path/to/file +++ b/path/to/file which means that the 'ape/patch -p1' used within git/import will just work. So with this, if you send an email to the mailing list, write up a committable description, and append the output of git/diff to the end of the email, git/import should just work.

I'd fix them as well all at once. I'm sure there are all of sorts of inconsistencies all over the place, but expecting anyone to review and fix everything at once is too much, it won't happen. If you see any others right now, it would be nice to fix them too, in my opinion.

person who creates a commit separately from the person who wrote the commit. For git9, we ignored this feature. However, as we start using git/import more, it will be useful to figure out who imported a commit, as well as who wrote it. This change adds support for seeing this information in git, as well as setting the author and committer separately in git/import. diff ad26f82e44a5f59383edfde5f4c3727c225f4b0a uncommitted --- a//sys/lib/git/common.rc +++ b//sys/lib/git/common.rc @@ -38,7 +38,22 @@ status=() } -# merge1 out theirs base ours +fn whoami{ + name=`{git/conf user.name} + email=`{git/conf user.email} + if(test -f /adm/keys.who){ + if(~ $name '') + name=`{awk -F'|' '$1=="'$user'" {x=$3} END{print x}' mode = 0755 | DMDIR;

So, lots of these look like some bike-shedding for the sake of bike-shedding, without really improving the quality of the documentation. For example, is 'foreign-character-set' really an improvement over 'foreign character-set'? Is character-set an improvement over character set? I think both changes are worse. On the other hand, there are actual fixes for omissions, like: -.B "newdev {low|full|high} \fIport\fP +.B "newdev {low|full|high|super} \fIport\fP and styling issues like: -.I str , +.IR str , If I could have this without the bikeshedding, that would have been ideal. Anyways, I think qwx is looking at this patch, so I'll let them handle it.

Thanks Amavect From: Amavect Date: Sat, 21 Aug 2021 18:41:01 +0000 Subject: [PATCH] cmd/mkfile: major cleanup Target generation is revised, split into $YTARG and $TARG. $PROGS is inlined to the cmd target. %.cpus is added to allow chaining: mk all.cpus $POWERLESS is added, since dtracy doesn't build yet on ppc. $cpuobjtype is replaced with cp's recipe for copying itself on $cputype. $APEDIRS is removed. The none target is renamed to usage, since it prints out usage. The ape target is removed. The dirs target is replaced by all.dirs %.directories is replaced by %.dirs The all target serializes directories after cmds to match the install target recipe.

Chatted with ori yesterday. He had some good ideas with simplifying $NOMK and $DIRS generation. TODO: init.c doesn't really belong in cmd/ and should probably be moved to /sys/src/boot/ since it complicates cmd/mkfile. That will be a separate patch.

We actually ran into this once in the 9front repo: commit 185fe31de404b67441248d91e6321645278ba92a will request a supurious merge if you pull from it. This is because when faced with a commit graph like this: ---a---b---c---d---e \ / +-----f----+ and we want to find the least common ancestor of commits 'b' and 'e', we will return commit 'a'. This is technically the correct answer: we can get to 'a' with 1 step from 'e', and 2 from 'e', for a total of 3 steps, which is shorter than the number of steps to get from 'e' to 'b' directly However, for every practical purpose of the LCA algorithm, if a node is an ancestor of another, we want to return that ancestor, rather than the node which can be reached from all parents in the smallest number of steps. This means that we need to keep scanning until we've visited all potential ancestors between the two nodes, and picking the shortest distance between nodes reachable from 'e' and the nodes reachable from 'b'. We already have code that almost does this, in our findtwixt() code, painting backwards from a set of 'head' and 'tail' nodes in parallel until there are no more nodes reachable from 'head' without crossing over 'tail'. Since we paint until all nodes reachable from head are painted, we're guaranted to encounter the ancestor we want to return if it's present. This change takes findtwixt() and refactors it into a paint function which, when passed 'ancestor=1', will return the lca rather than the full set of covered nodes. Along with these changes are a few refactors to prevent exponential blowups in time when repainting a graph of mostly-done nodes, by bailing out early: this made pulling git (commits a5fa49ff0 => c4203212e36) take tens of seconnds instead of more than tens of minutes. As a bonus, we delete some code by doing this refactor. Since bugs here can lead to issues sysupdating, I'd like some extra eyeballs, testing, and review on this before I commit. diff e6f0abc25e4e237fff97ef9bdd1dc98ee519def8 uncommitted --- a/sys/src/cmd/git/ref.c +++ b/sys/src/cmd/git/ref.c @@ -22,17 +22,11 @@ int stksz; }; -struct XObject { - Object *obj; - Object *mark; - XObject *queue; - XObject *next; -}; - struct Objq { Objq *next; Object *o; int color; + int dist; }; static Object zcommit = { @@ -128,110 +122,6 @@ return 1; } -XObject* -hnode(XObject *ht[], Object *o) -{ - XObject *h; - int hh; - - hh = o->hash.h[0] & 0xff; - for(h = ht[hh]; h; h = h->next) - if(hasheq(&o->hash, &h->obj->hash)) - return h; - - h = emalloc(sizeof(*h)); - h->obj = o; - h->mark = nil; - h->queue = nil; - h->next = ht[hh]; - ht[hh] = h; - return h; -} - -Object* -ancestor(Object *a, Object *b) -{ - Object *o, *p, *r; - XObject *ht[256]; - XObject *h, *q, *q1, *q2; - int i; - - if(a == b) - return a; - if(a == nil || b == nil) - return nil; - r = nil; - memset(ht, 0, sizeof(ht)); - q1 = nil; - - h = hnode(ht, a); - h->mark = a; - h->queue = q1; - q1 = h; - - h = hnode(ht, b); - h->mark = b; - h->queue = q1; - q1 = h; - - while(1){ - q2 = nil; - while(q = q1){ - q1 = q->queue; - q->queue = nil; - o = q->obj; - for(i = 0; i < o->commit->nparent; i++){ - p = readobject(o->commit->parent[i]); - if(p == nil) - goto err; - h = hnode(ht, p); - if(h->mark != nil){ - if(h->mark != q->mark){ - r = h->obj; - goto done; - } - } else { - h->mark = q->mark; - h->queue = q2; - q2 = h; - } - } - } - if(q2 == nil){ -err: - werrstr("no common ancestor"); - break; - } - q1 = q2; - } -done: - for(i=0; inext; - free(h); - } - } - return r; -} - -int -lca(Eval *ev) -{ - Object *a, *b, *o; - - if(ev->nstk < 2){ - werrstr("ancestor needs 2 objects"); - return -1; - } - a = pop(ev); - b = pop(ev); - o = ancestor(a, b); - if(o == nil) - return -1; - push(ev, o); - return 0; -} - static int repaint(Objset *keep, Objset *drop, Object *o) { @@ -249,29 +139,57 @@ for(i = 0; i < o->commit->nparent; i++){ if((p = readobject(o->commit->parent[i])) == nil) return -1; + if(oshas(drop, p->hash)) + goto next; if(repaint(keep, drop, p) == -1) return -1; +next: unref(p); } return 0; } -int -findtwixt(Hash *head, int nhead, Hash *tail, int ntail, Object ***res, int *nres) +static int +haskeep(Objq *q) { + for(; q != nil; q = q->next) + if(q->color == Keep) + return 1; + return 0; +} + +static int +bestpick(Hash *head, int nhead, Hash *tail, int ntail, Objq *q, int dist) +{ + int i; + + if(q->dist < dist) + return 1; + for(i = 0; i < nhead; i++) + if(hasheq(&head[i], &q->o->hash)) + return 1; + for(i = 0; i < ntail; i++) + if(hasheq(&tail[i], &q->o->hash)) + return 1; + return 0; +} + +static int +paint(Hash *head, int nhead, Hash *tail, int ntail, Object ***res, int *nres, int ancestor) +{ Objq *q, *e, *n, **p; Objset keep, drop; - Object *o, *c; - int i, ncolor; + Object *o, *c, *best; + int i, dist, ncolor; e = nil; q = nil; p = &q; + best = nil; + dist = 1<<30; osinit(&keep); osinit(&drop); for(i = 0; i < nhead; i++){ - if(hasheq(&head[i], &Zhash)) - continue; if((o = readobject(head[i])) == nil){ fprint(2, "warning: %H does not point at commit\n", o->hash); werrstr("read head %H: %r", head[i]); @@ -286,13 +204,12 @@ e = emalloc(sizeof(Objq)); e->o = o; e->color = Keep; + e->dist = 0; *p = e; p = &e->next; unref(o); } for(i = 0; i < ntail; i++){ - if(hasheq(&tail[i], &Zhash)) - continue; if((o = readobject(tail[i])) == nil){ werrstr("read tail %H: %r", tail[i]); return -1; @@ -306,6 +223,7 @@ e = emalloc(sizeof(Objq)); e->o = o; e->color = Drop; + e->dist = 0; *p = e; p = &e->next; unref(o); @@ -312,7 +230,7 @@ } dprint(1, "finding twixt commits\n"); - while(q != nil){ + while(haskeep(q)){ if(oshas(&drop, q->o->hash)) ncolor = Drop; else if(oshas(&keep, q->o->hash)) @@ -319,18 +237,36 @@ ncolor = Keep; else ncolor = Blank; - if(ncolor == Drop || ncolor == Keep && q->color == Keep) + dprint(2, "visit: ncolor=%s, qcolor=%s %H\n", + ncolor == Keep ?
