I'm not sure how much we claim to support building openSUSE rpm's as source rpm's on there own. openSUSE rpm spec files often depend on variables that are defined in project config files in open build service, as such just using rpmbuild may result in packages not building or building with different configurations.

---- But is *installing* "rpms" from tumbleweed, with "rpm" on a tumbleweed install, supported?

The reason I was trying to build _rpm_ from source is to get an rpm with the "PayloadIsZstd" feature, since my local rpm doesn't have that feature. It really wouldn't help to build rpm on OBS if it would just give me an 'rpm' that I can't install on my machine due to prereqs.

The thing is, is that I was able to get down to building "rpm" but only had PayloadIsZstd as a requirement of a local attempt to build that would run with the packages and libraries I currently have installed.

I don't want to rebuild the same uninstallable binary rpm package that is currently distributed with "encrypted" (using a "secret", new new encoding(compression lib) that can _only_ be built from packages that require the same encoding in order to be installed.

I.e. I can't install the binary rpm, because it has 8 pre-reqs on other rpm packages that expand to some 30+ packages all that cannot be installed due to the fact that they require the "PayloadIsZstd" rpm feature.

I find myself unable to build the binary rpm on my system because it requires 'devel' packages all that require the 'PayloadisZstd'.

I tried building the Zstd lib, but it also requires binary packages that require the same feature -- i.e. a **circular dependency**. This disallows INSTALLING any needed rpm's that one might need to even build those same rpm's from their source rpms. I realize that sources for GNU licensed binaries appears to be included but the sources for those new binaries are inaccessible because they are encoded in the new compression scheme.

I'm pretty sure that requiring a user to only build tools in suse's OBS, as a pre-condition for satisfying GNU's requirement for including source with redistributed binaries is not considered a valid way of establishing a "locally trusted" build environment. _Part_ of the reason the sources are open is that the user may regenerate binaries on their local machines to satisfy various "chain of trust" requirements on the build tools and machine.

This, ultimately, boils down to variations on Ken Thompson's "Reflections on Trusting Trust" (as from: http://www.cs.cmu.edu/~rdriley/487/papers/Thompson_1984_ReflectionsonTrustin gTrust.pdf ).

Perhaps this sounds a bit remote, but being unable to install rpm's because rpm can't read +install the dependency libs it needs to run itself, reminds me a bit of having 'mount' on your root partition and a 'libmount' on a yet-to-be-mounted '/usr/ partition. :-/ Did you ever hear of zypper ?

AFAIK, zypper uses the command rpm or the rpm libraries to do the actual installation. Same problem. -- Cheers / Saludos, Carlos E. R. (from 15.1 x86_64 at Telcontar)

openSUSE Tumbleweed maintains backward compatibility to the latest openSUSE Leap/SLE 15.x release. Compatibility beyond that is not assured in any way. You should update your SLE 12 system to SLE 15, if you can.

She needs forward compatibility. She has to update a TW machine that was not working for two months, so that it missed the rpm upgrade to the new payload compression scheme. Zypper fails because the packages she now downloads are compressed with an algorithm that the zypper and rpm she has in the machine can not decode.

That's why rpm itself is always packaged with bzip2, so that you can upgrade rpm using rpm to a version that knows how to decode zstd.

Well we still support upgrading from Leap to Tumbleweed and upgrading older tumbleweed installs so if people update using the supported method of zypper dup someone has put in the effort to make it work I haven't looked at how they have done that.

  In a supported up to date system we provide all the tools required to view and install source rpm's,

   But not build?

Not without additional effort, there are a number of macro's and definitions here ( https://build.opensuse.org/projects/openSUSE:Factory/prjconf ) for example that you would need to teach rpm about if you were going to do a build outside open build service.

   The point here, is that my linux server was off-the-internet for a couple of months.  Before it went off line, I was able to install rpm's from tumbleweed or build them.  After a few months offline, my system came back online but without my local copies of the tumbleweed repo.  I downloaded a copy and found I wasn't able to install any binary packages due to the binary format changing.  Simply trying to build from the source required I install other binary (all 'devel') packages that were unreadable/inaccessible.    FWIW, system was offline because of main disks becoming corrupted by a flakily repaired RAID card that eventually overheated due to the bad repair -- I didn't know it was bad until I got a replacement and noticed that the older card probably wasn't 'new' -- it was missing pressure screws that held a heat sink on a hot chip -- and to keep it on, someone had used something like superglue -- not a great heat conductor IMO.  While the backup went offline as well and had some problems, I was able, with new enclosures and a new card, to restore OS+most files from those backups.

   The problem was keeping my system "up-to-date" when the primary disks were down -- obviously that was not possible.  This was an up-to-date system, that got out of sync as a transition was made to a new rpm format.    One of the problems I am highlighting is the inability to resync a local installation after being forced offline for a few months.  This is being complicated by suse-rpms's that, it seems, are no longer supported being used to rebuild rpms locally, primarily because there is no stand-alone converter to convert binary-rpms to a readable format for systems more than a few months old (more like 6 months, now) that only have the old rpm installed and don't have a matching set of binary-rpms for what is installed.  They were on a disk that wasn't part of the backups because I had just downloaded them and thought I'd be able to do so again.

From our build service you can find and inspect all the build logs along with the source tarballs, beyond that obs has the ability to verify that upstream tarballs have been used along with signature checking. The Reproducible builds team has also done a lot of work in this area so generally i'd say we are doing better then most distro's.  

---

   That may be true, I haven't examined enough others to say, but that doesn't address the ability to build locally or examine which patches get applied to various rpms during the build process.  Some of suse's rpm's apply huge numbers of unsigned patches...for example, in looking at opensuse's rpm source for 4.15.1, there are 63 patches.

   Then there are: ..."the spec files" that include dependencies and variables "that are [only] defined in project config files in in the open build service".  <<< Some or most of those should be able to be set in a script as part of a non-obs build phase.  Otherwise, you have: "just using rpmbuild may result in packages not building or building with different configurations".    It's the "not building" part that I'm hitting right now.

   As for zypper -- will try it again, but last try had it trying to switch in over 200 packages  -- just to upgrade 'rpm' -- and that was after I  ignored some problems. Sigh.

I would expect that if rpm and its dependencies all came from the standard repo and that you had been updating your system with `zypper dup` in the past you should be able to still upgrade your system with `zypper dup` not being able to would be a bug worth reporting.

YES - But: as the payload compression changed, we have always been aware that no matter how long we will make the payload change, there will be some user takign n+1 days until they will update.

To be clear: we enabled zstd support in RPM in Tumbleweed before we switched to zstd compresson method. And the timing was already quite conservative:

RPM had zstd support in Tumbleweed since July 2019 (2019 - aka > 1 year ago) TW changed the default compression scheme to zstd on August 25 2020 (i.e. more than a tear after we added support to rpm reading those payloads)

Leap 15.2 also received a maintenannce update to be able to read those zstd payloaded rpms. Upgrading to TW has always been supported from the 'latest openSUSE stable release and from Tumbleweed'

A TW user that actually managed to miss the 1-year period to upgrade

She said the machine was current, then had hard disk trouble for two months. Then it failed to update.

RPM to support zstd payload, still is not lost: the TW instance cna be 'offline upgraded' (i.e. boot the NET install/DVD and pick 'upgrade' in the bootloader. This will use RPM on the DVD/NEt and allow to move to a current TW snapshot).

This is one of the procedures I recommended. She has not commented back yet.

Anything else you're trying to do, is out of the supported scenarios,

   Of course!  Though am making progress -- am able to build a copy of zstd from the source rpm, but the source rpm gets errors which I haven't sorted out yet.

No, this is a documented procedure. It is the same procedure as used to upgrade a machine from 13.1 to 13.2 before zypper dup was invented. And, it can be used as well for emergency recovery of broken systems. Try it out in a virtual machine.

I think I need a libzstd.sa from the devel pckg as well as well as some needed header. I tried using the zstd.h from the package build, but don't know if it is what is needed.

  Well it installs no prob, (no conflicts), but I think I also need the -devel rpm: I tried: libzstd1-devel-1.4.5-2.2.x86_64.rpm, but that returns a

      pkgconfig(libzstd) is needed by rpm-4.15.1-7.2.x86_64

Does the devel hold that info?

Yes, its looking for /usr/lib64/pkgconfig/libzstd.pc (or something similar).

I tried finding the "-devel" package, by using a similar version as the rpm for the 'libzstd', but couldn't  find it. Do you know the name of the corresponding 'devel' rpm that would install libzstd.pc (as well as libzstd.a  & libzstd.h)?

Finding which package provides something is easily done with zypper

    zypper se --provides "pkgconfig(libzstd)"

So you probably need to install 'libzstd-devel'

Yeah rpm automatically adds this provides as part of the build process. So its checking for the rpm that provides that rather then for something on the filesystem. -- Simon Lees (Simotek) http://simotek.net Emergency Update Team keybase.io/simotek SUSE Linux Adelaide Australia, UTC+10:30 GPG Fingerprint: 5B87 DB9D 88DC F606 E489 CEC5 0922 C246 02F0 014B
