First is that features today (EntryUUID, LDAPSsoToken) are both locked behind another language. Rightly so, they shouldn't be hidden here forever. As well, Mark wants to ask what it would take to enable by default. >> >> ** Why did I use the fedse.c to load a plugin entry? >> >> Because we don't (fully) support startup migrations yet. Mark has privately reminded me that he has reviewed https://pagure.io/389-ds-base/pull-request/49579 and that I should revive it. This v4 plugin adds a stateful assertion of entries allowing better migrations beyond what fedse.c's bootstrap can achieve. IE we can create an entry if it does not exist, and modify it partially if an admin has changed it (ie we can tweak defaults but without affecing say pluginEnabled). There was an issue viktor raised about pbkdf2 where it could not be disabled, and this would resolve it. Most likely, I will break the on startup migrations out from the v4 plugin patch set, and make it it's own change, and move some of the content from fedse.c and friends into this. >> >> ** TODO list to get rust enabled by default. >> >> I think there is still a bit of work to do to enable by default, but I think we are pretty close.

The build took a lot longer :-( but it worked ;-) It'll get quicker with some of the cleanups I want to do, but release builds with rust will be a lot slower due to the fact they can perform more aggressive optimisation because of the stronger type rules AND they can also do stuff like LTO where we don't in 389 atm. https://gcc.gnu.org/wiki/LinkTimeOptimization >> - william -> fix the intentional name leak in the rust slapi plugin interface to use lazy_static.

Sure, we'll need to test that at some point to be sure.

I really want to make sure we do this right as a team, and we are all happy with it (I don't want a repeat of nunc-stans ;) ). If we agree on this, I will open some tickets up, add the relevant blocks/ordering and assign out the work. > > Thanks for getting this discussion started! I think we already have most of this in place to use rust by default today, but we need to do some more testing, etc. For sure! Also worth noting that don't have to be the one to do all the "william" items, if other people want to step up they can. I need to tidy up this syncrepl stuff and finish up openldap migration stuff, but I think the rust tools will be a valuable part of that openldap migration so I will do it sooner than later :) > > Thanks, > > Mark > >> >> Thank you all! >> >> — >> Sincerely, >> >> William Brown >> >> Senior Software Engineer, 389 Directory Server >> SUSE Labs >> _______________________________________________ >> 389-devel mailing list -- 389-devel@xxxxxxxxxxxxxxxxxxxxxxx >> To unsubscribe send an email to 389-devel-leave@xxxxxxxxxxxxxxxxxxxxxxx >> Fedora Code of Conduct: https://docs.fedoraproject.org/en-US/project/code-of-conduct/ >> List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines >> List Archives: https://lists.fedoraproject.org/archives/list/389-devel@xxxxxxxxxxxxxxxxxxxxxxx > > -- > > 389 Directory Server Development Team > — Sincerely, William Brown Senior Software Engineer, 389 Directory Server SUSE Labs _______________________________________________ 389-devel mailing list -- 389-devel@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to 389-devel-leave@xxxxxxxxxxxxxxxxxxxxxxx Fedora Code of Conduct: https://docs.fedoraproject.org/en-US/project/code-of-conduct/ List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/389-devel@xxxxxxxxxxxxxxxxxxxxxxx
