gdal building is failing on F27 due to another reason (not mariadb
related)...

There is an open bug:

Rex, the 10.2.7-2 version is finally out (after 20h of building :/ )

I did a scratch build of the 'os-autoinst' package and it looks like it
does not complain about the missing symbols anymore:
https://koji.fedoraproject.org/koji/taskinfo?taskID=20519110

Did that solved the issue, or am I just looking to the wrong place?

Look, I'm just trying to fix what the maintainer did. I'm not
interested in creating an entire new compat package, I'd rather just
work on rebuilds than do that.

The point is, if we get the 'compatibility' stuff right, *nothing*
should *need* rebuilding - the intent of the compatibility bits was to
make packages built against MariaDB 10.1 keep working fine, while
things that did get rebuilt would be linked against the new soname.
Then once everything was rebuilt, we could remove the compat bits. At
least, I think that's what Michal was aiming for. If it all worked
right, it should be possible to build os-autoinst fine without gdal
being rebuilt for the new mariadb soname at all.

It turns out there was one rather embarrassing problem with my attempt
to fix the compat bits: I moved the versioned symlink into the -libs
subpackage, but didn't change its target from the unversioned library
to the versioned one, so unless you had the -devel package installed,
it was just a dangling symlink :/

Michal caught that and sent a fixed build, but it got caught up in the
mess that's happening today with the s390 builders so it hasn't
actually made it out yet. Once all that mess gets resolved, we'll be
able to see if the compat stuff is working.

I've also started working on fixing things that failed to rebuild
against the new soname.

non-verbose build.log aside, I'm pretty sure that:
usr/lib64/libgdal.so.20: undefined reference to 
`mysql_error@libmysqlclient_18'
type errors, means libgdal likely needs rebuilding first, before any of it's 
dependencies.

I'm afraid even this build doesn't entirely work right, for some
reason: see this build failure I just got notified about by koschei:

https://apps.fedoraproject.org/koschei/build/3070598
https://kojipkgs.fedoraproject.org/work/tasks/3960/20493960/build.log

Note the errors at the end all relate to libmysqlclient and one claims
it cannot be found, though the root.log shows the 10.2.6-4 package was
installed. I think we need to do something else: revert back to 10.1
till we're ready, set up a proper compat- package, or ditch the compat
stuff and just get all the dependent stuff fixed and rebuilt ASAP.

[Michal Schorm]

A new version of MariaDB 10.2-4 is out, it now has fixed symlinks and
Provides.
Bugzilla tracker of issues in other packages should be filled up soon.

The symlinks should stay around for a while, so all packages will have a
time for transfer to the new library. However they will be removed (planned
sometimes before f27 release)

So this is now happening, but I'm a bit confused - specifically about
these two bits from the text:

"Either the rebuild of all depending packages is inevitable."
"this means also drop of symlinks to "libmysqlclient.so.18.0.0"
library"

However, the recent mariadb package builds by mschorm - mariadb-10.2.6-
1.fc27 and mariadb-10.2.6-2.fc27 - included symlinks from
'libmariadb.so' to 'libmysqlclient.so' and 'libmysqlclient.so.18'.
Which seems to imply that the library *should* still be ABI-compatible
with libmysqlclient.so.18 and that things built against that library
should *not* need rebuilding.

The libmysqlclient.so.18 symlink was initially put in the -devel
subpackage, which was clearly wrong, and after discussion with mschorm
I moved it to the -libs subpackage. But after reading some more on this
I'm really not at all clear on why this symlink exists, whether it was
intended to, whether it's *correct* that it exists, whether it's only a
temporary stopgap, etc. etc. So I thought I'd send out a mail about the
situation so we can discuss it on the public record.

There's still a problem with the -3 build I did, with the symlink
moved: the -libs package does not automatically get a Provides: for the
libmysqlclient.so.18 symlink, for some reason. I *could* do a rebuild
with the Provides: manually added, but now I'm unsure whether that's
the right thing to do.

This is a bit of a problem because it prevents various things from
building; the one that got me into this mess is initial-setup , which
needs rebuilding to fix a blocker bug, but the build failed because
somehow on s390 (only) initial-setup build requires net-snmp and net-
snmp requires libmysqlclient.so.18...

Can we sort this out, one way or another? Thanks!

Yeah MariaDB 10.2.6 Stable (GA) finally implemented features from MySQL
5.6 and 5.7.

As a PostgreSQL user, I have no idea about this.

Is one better than the other?

It seems as if from the last link that we decided to replace MySQL
with MariaDB (and for good reason if Oracle are not providing CVE
information).  Has that decision been rolled back so now we'll package
both in parallel indefinitely?

Are there any stats on which of the forks is more popular?

Rich.

I'm not sure how the Provides have been tweaked, but
community-mysql-devel and mariadb-devel provide the same resources. In
fact, they conflict with each other.

We have both today, so I think that's now necessary...

Are we also going to package MySQL?  And if so, will that mean that
packages like ocaml-mysql (MySQL bindings for OCaml) will have to be
forked into ocaml-{mysql,mariadb}?

At least is behind schedule,  mysql-community supports json fields
while in MariaDB we are waiting

What you wrote is an API change
=> MariaDB is not a drop-in replacement for MySQL anymore.

The "many ṕackages requiring changes" you mentioned furtherly manifest this.

Nope.

MariaDB is a drop-in replacement. In version 5.5.

For quite a time we use MariaDB 10.1, which openly declared "Now we know
what we are doing and now we know where do we want to go".
MariaDB 10.2 just take another step forward in technology and away from
MySQL.

[SONAME change] MySQL, MariaDB

[Michal Schorm]

Hello everybody!

Since MariaDB 10.2 is finally stable and I resolved all issues that blocked
it for Fedora, I'd like to propose an update for Rawhide.

Current version of MariaDB: 10.1.24
Update planned to: 10.2.6 (or newer)

*This change introduces change of library name from "libmysqlclient.so" to
"libmariadb.so".*
*There are many dependant packages affected.*

The current (optimistic) plan is to deliver the update before Fedora 27 mass
rebuild  at 12.7.2017.
Either the rebuild of all depending packages is inevitable.

-

We actively track the issue here
. There is also a list
of affected packages.
We have a work repository in COPR, where you can find builds of your
packages here
.

We go through all of the issues and we are trying to solve all of those,
which are caused by the library change. More information will appear in
bugzillas connected to the tracker.

Issues are also consulted with MariaDB upstream.
I was told, that there should be strong API and ABI compatibility.

-

Notes:
 - this means also drop of symlinks to "libmysqlclient.so.18.0.0" library.
 - the version of the library in MariaDB 10.2.6 is "mariadb.so.3", however
in mariadb-connector-c it is only "mariadb.so.2". That should sync in next
big update in about a month, I believe.

-

Feel free to ask any questinos here or in tracker BZ, I'll try to search
for all answers.
