Using usr.sbin/trim as an example. If it's external it should should live in ports and be installed in $LOCALBASE. A quasi src repo in ports to install software outside of $LOCALBASE doesn't make any sense. ALso see my comment about pkgbase. I expect pkgbase to homogenize base and ports into a seamless install. Alternatively pkgbase and ports could use different package repos. For example when I was an MVS sysprog, MVS and JES were installed in one repo while CICS and IMS were installed each in their own repos. That was site specific but not out of the realm of possibilities here either. -- Cheers, Cy Schubert FreeBSD UNIX: Web: http://www.FreeBSD.org The need of the many outweighs the greed of the few. ___ svn-src-all@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/svn-src-all To unsubscribe, send any mail to "svn-src-all-unsubscr...@freebsd.org"

If it must live in one of our repositories, then a users, projects or other hierarchy in ports might be acceptable. However there would be too great a temptation to fork a random piece of software on the internet. baseports/usr.bin/whatever doesn't make much sense. If it's in ports it should use the ports infrastructure and install in $LOCALBASE. If it's in ports, it's not in base and should not be installed outside of $LOCALBASE. If it's to be installed in for instance, /usr/bin, then it must live in usr.bin. > > I really really dislike the idea of putting stuff from base in > external repositories and then fetching them, something just > feels fundementally wrong about that. Trim should not be in base/. If it's in ports it should be installed in $LOCALBASE not outside it. The point is, trim should not be in base. It should not live in /usr/src nor should it be installed outside of $LOCALBASE. If anything, as is it could be a port. It should not live in a user or project branch of base nor should it be sourced out of some hypothetical quasi FreeBSD source repository in ports or any other FreeBSD repo for that matter. It doesn't belong here at all. It's function can however be provided by dd. -- Cheers, Cy Schubert FreeBSD UNIX: Web: http://www.FreeBSD.org The need of the many outweighs the greed of the few. ___ svn-src-all@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/svn-src-all To unsubscribe, send any mail to "svn-src-all-unsubscr...@freebsd.org"

I don't have any hard numbers on hand but my recollection is it caps out at about 5 GB/s, total, on Broadwell. Our workload with it is predominantly unmapped 8kB copies but includes some 512 byte copies as well. My recollection is that the channels are logical and share a single DMA engine, so there's not much reason to use more than one of them. It may improve on future microarchs but I can't speak to those.

I strongly disagree that dd is the proper place for this tool, dd is far to easy a way to destroy data when trying to do this type of operation and should be the last choice for implementing what is normally a very safe thing to do. And as eugene points out dd can not easily be made to do "trim ada0 ada1 ada4" which is probably the far more common use of this command. dd's ability to do sparse(ing) of a file should NOT be overloaded with a device layer block trimming function. > > > > If you want to socialize, revive, or expedite someone else's review, > > maybe add a new comment to the review, or post a discussion hackers@, > > or something like that.

Correct me if I am wrong, but you seem suggesting that every src developer would also need some external account (github in this example) to maintain his or her chunk of code independently of everyone else's. This is pretty much a no-go from starters. There are also many more major issues with such approach, such as completely different branching model for src and ports as an example. ports is a good framework in general, for maintaining software produced by external entities. I don't feel it's very appropriate for maintaining software produced by the Project itself, though, due to complexity inherited with that. We need something simpler and more self-consistent, at the same time I see no reasons why it could not utilize some if not all tooling with we build around ports/Mk over the years. IMHO. -Max ___ svn-src-all@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/svn-src-all To unsubscribe, send any mail to "svn-src-all-unsubscr...@freebsd.org"

Your response does not address *any* of the above concerns. It's just unrelated. The review you linked to isn't one you submitted for this change; it's Warner's, and that one stalled because you were such a jerk to him last time that he needed time off from you.

Ports supports GitHub out of the box, so this seems like a low barrier for entry (the bonus of doing this is that the projects could potentially be used by other non-FreeBSD projects, and contributed by others outside the FreeBSD project; the downside is having to deal with FreeBSD CI, as Travis CI only supports Linux (IIRC making Travis support FreeBSD is a non-trivial project, but it’s likely a very worthwhile goal, as it would make it easier to catch issues upfront with third-party projects that FreeBSD consumes, like llvm), enforcing style (can be done with git commit hooks and GitHub checks), etc. I would really like to do these things because it’s difficult getting folks to support FreeBSD in third-party projects as-is. Lowering the barrier of entry would allow FreeBSD and its developers to better scale (and make FreeBSD more of a first-class OS). > Perhaps even by forking the whole ports idea into a smaller closely-guarged > subset.

Re: svn commit: r343118 - in head/usr.sbin: . trim
What I think we really need is some way to easily porti-ze useful stuff that would otherwise go into /usr/[s]bin, so adding things would be just as easy as hooking up SUBDIR into usr.[s]bin/Makefile. Yes, I know, this is topic almost as old as the FreeBSD Project itself, but perhaps we just did not approach it the right way. It was always the idea that we would just move bunch of stuff from src/usr.[s]bin repo into ports/. Which brings several important question such as "who is to host the distfile"? "where sources hosted", "who is to update the port when changes happen?" etc. Perhaps even by forking the whole ports idea into a smaller closely-guarged subset. Something like a new baseports repository, which might have structure like baseports/usr.bin/xxx, baseports/usr.sbin/yyy etc. Then add some automagic glue to kick in on every commit and transfer this into valid ports, which is going to be packaged by the poudriere and such. This way we could reduce amount of port-foo average src committer needs in order to maintain code. I am almost tempted to sit and write something over the next weekend or few of thereofs. Using usr.sbin/trim as an example. -Max On Thu, Jan 17, 2019 at 12:47 PM Cy Schubert wrote: > In message il.com> > , Conrad Meyer writes: > > On Thu, Jan 17, 2019 at 12:22 PM Cy Schubert > wrot > > e: > > > This is wrong.

There is already https://reviews.freebsd.org/D18382 that had no code updates over 6 weeks and latest revision needs a fix as it is broken.

Please back it out; stop attributing code review to "hackers@," which can not (it's a list, not individuals) and did not review this changeset; and put it on phabricator for actual review. I think summary backout is warranted on the basis of your handling of this last time around and lack of attempt to solicit review for this time.

Revert r343095
This was intended to fix the soft reset timeout on boot for OrangePi One/R1
with internal PHY, but seems to cause other problems later on due to soft
resetting around some state changes that may or may not make the NIC
non-functional.
Reverting this for now while a better solution is sought out.

svn commit: r343117 - head/usr.bin/cmp
Author: markj
Date: Thu Jan 17 17:36:18 2019
New Revision: 343117
URL: https://svnweb.freebsd.org/changeset/base/343117
Log:
Fix handling of rights on stdio streams.
- Limit rights on stdio before opening input files. Otherwise, open()
may return one of the standard descriptors and we end up limiting
rights such that we cannot read from one of the input files.
- Use caph_limit_stdio(), which suppresses EBADF, to ensure that
we don't emit an error if one of the stdio streams is closed.
- Don't bother further limiting rights on stdin when stdin isn't going
to be used. Doing so correctly requires checking for a number of
edge cases, and it doesn't provide any significant benefit.
