--000000000000feca5b060cba3bd4 Content-Type: text/plain; charset="UTF-8" Content-Transfer-Encoding: quoted-printable ---------- Forwarded message --------- From: Luca Pizzamiglio <pizzamig@freebsd.org> Date: Sat, Dec 16, 2023 at 7:36=E2=80=AFPM Subject: Support for subpackages in the portstree is going to land soon! To: developers <developers@freebsd.org> Hi everyone. It's with pleasure that we are announcing that soon the portstree will support subpackages. Subpackage is the feature to create multiple packages from one port. There has been a lighting talk at EuroBSD 2023 ( https://youtu.be/e-FUYbGNdBg?t=3D824) introducing the topic. While this feature is used in many Linux distro to split packages (i.e. -docs, -srcs, -devel, -man or similar), this is *not* the intended goal we have. Our primary goal is to get rid of ports that are currently compiled separately in order to be packaged separately. Examples are php modules or qt libraries, currently using the so called master/slave port approach. Build time will benefit from it. The slave ports will become subpackages of the master port (we can keep the build optional via OPTIONS). This doesn't mean that all ports based on master/slave need to adopt subpackages, there will be situations where it won't be possible. We want to merge the feature in the framework now (end of the year), but adopt it in ports slowly over the next quarters. To limit the adoption, we will deploy a git hook server-side to request approval from portmgr before introducing subpackages for specific ports. While poudriere (3.4.x) already supports subpackages, other tools don't, and we want to give time to their maintainer to add support. The slow adoption will also allow us to catch problems one at a time and fix them. The patch is available for review here: https://reviews.freebsd.org/D40549 This implementation is heavily based on mat@ (7 years) old implementation ( https://reviews.freebsd.org/D16457) We don't have documentation yet, but another patch ( https://reviews.freebsd.org/D43079) containing two fake ports, used to build and test this feature. They provide the best example of how subpackages would look like and they will be used to write the documentation. The roadmap * successful EXP-RUN to not introduce regressions ( https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D275735#h0) * add a git hook server-side to allow only controlled adoption * merge the support of subpackages in the portstree (before 2023.12.31) * prepare and update the handbook * success! There will be a lot of questions, I will answer to all of them, but give me some time, I could be AFK from time to time during holiday season. Best regards, pizzamig on behalf of portmgr --000000000000feca5b060cba3bd4 Content-Type: text/html; charset="UTF-8" Content-Transfer-Encoding: quoted-printable <div dir=3D"ltr"><br><br><div class=3D"gmail_quote"><div dir=3D"ltr" class= =3D"gmail_attr">---------- Forwarded message ---------<br>From: <b class=3D= "gmail_sendername" dir=3D"auto">Luca Pizzamiglio</b> <span dir=3D"auto"><= ;<a href=3D"mailto:pizzamig@freebsd.org">pizzamig@freebsd.org</a>></span= ><br>Date: Sat, Dec 16, 2023 at 7:36=E2=80=AFPM<br>Subject: Support for sub= packages in the portstree is going to land soon!<br>To: developers <<a h= ref=3D"mailto:developers@freebsd.org">developers@freebsd.org</a>><br></d= iv><br><br><div dir=3D"ltr"><div>Hi everyone.<br><br></div><div>It's wi= th pleasure that we are announcing that soon the portstree will support sub= packages.</div><div><br></div><div>Subpackage is the feature to create mult= iple packages from one port.</div><div>There has been a lighting talk at Eu= roBSD 2023 (<a href=3D"https://youtu.be/e-FUYbGNdBg?t=3D824" target=3D"_bla= nk">https://youtu.be/e-FUYbGNdBg?t=3D824</a>) introducing the topic.<br></d= iv><div>While this feature is used in many Linux distro to split packages (= i.e. -docs, -srcs, -devel, -man or similar), this is <b>not</b> the intende= d goal we have.<br></div><div>Our primary goal is to get rid of ports that = are currently compiled separately in order to be packaged separately.
