One needs transaction semantics when working on packages:

This isn't there by intention. Basically no scm implements it because it
blocks other people and slow downs development. Usually first submitter wins
and followers need to adapt.
I can not imagine any system right now, which solves social problems, in the
end people need always to talk to each other if they work on same code.
A weak synchronization point preferably with a kind of weak locking
before someone starts to change it (so that all others who also
work on it are at least informed) and a strong synchronization point
preferably with a kind of three way merge when changes are committed.
I do not understand how a weak synchronization point before
blocks other people and slow downs development.
The problem with the current build service is not the
optimistic concurrency control policy at commit time,
the problem is that nobody knows about others who may also work
on a package until it is too late to start collaborating.
Remember Coolo's mass-changes of packages.
All others notice what Coolo did only when it was already done.
If there was a "begin of transaction" the others could get
at least informed before.
But as you wrote - and as other threads here show - mutual information
is not really within the scope of the build service but is left to the
users of the build service to do it somehow on their own beside the
build service via manual mails.
The build service is just what it is called, a plain build service
but nothing more.
This is o.k. for me - I did just misinterpret what it actually is.
As far as I know the current build service does even not implementit does, check "osc log".
real revision control (like e.g. SVN).
This is mostly useless for me:
jsmeix@nelson:/obs $ osc log openSUSE:Factory cups
shows all entries with "unknown" and "<no message>" but I know
that I explicitely provided messages while I did "osc commit".
In contrast in my own working copy directory
jsmeix@nelson:/obs/Printing/cups $ osc log
shows more info but still not my "osc commit" messages.
In my own working copy directory I do not need such information
very much because in my own working copy directory I know well
what I did there.
In contrast it is crucial to have meningful "osc log" messages
when I query whatever package on the server to find out which
revisions are of particular interest regarding a particular issue.
