How to fix FreeBSD for cor­por­a­tions (and user with smal­ler in­stall­a­tions), the tools-​viewpoint

There is a huge dis­cus­sion go­ing on on hackers@ about how FreeBSD is not suit­able for large in­stall­a­tions (any­more?). As of this writ­ing, the dis­cus­sion seems to get some discussion-​clusters. We have some sub-​topics which could lead to some good im­prove­ments.

One sub­topic is the re­lease en­gin­eer­ing. Some changes like a more guided ap­proach of what should be merged to which branch, the fre­quency of re­leases and maybe some kind of long-term-branch(es). There is some dis­cus­sion to get maybe some joined-​funding in some way from in­ter­ested parties to pay someone to take care about long-term-branch(es).

An­other sub­topic is the way bugs are handled in our old bugtrack­ing soft­ware and how patches go un­noticed there.

And both of them are con­nec­ted (parts more, parts less) by what can be done in a vo­lun­teer pro­ject.

To me it looks like the pro­pos­als “just” need some re­fine­ments and some “vo­lun­teers” to put value (this means man power and/​or money) to what they said.

What I want to dis­cuss here is, how tools could help with mak­ing PRs/​patches more vis­ible to de­velopers (there is already the pos­sib­il­ity to get emails from the small bugbuster-​team about patches in PR data­base, but you have to ask them to get them) and how to make it more easy to get patches into FreeBSD.

Mak­ing bugs more vis­ible to de­velopers

The ob­vi­ous first: We need a dif­fer­ent bugtrack­ing sys­tem. We already know about it. There is (or was…) even someone work­ing IIRC on an eval­u­ation of what could be done and how easy/​hard it would be. I am not aware of any out­come, des­pite the fact that it is months (or even a year) since this was an­nounced. I do not blame any­one here, I would like to get time to fin­ish some FreeBSD vo­lun­teer work my­self.

In my opin­ion this needs to be handled in a com­mer­cial way. Someone needs to be of­fi­cially paid (with a dead­line) to pro­duce a res­ult. Un­for­tu­nately there is the prob­lem that the re­quire­ments are in a way, that people do not have to change their workflows/​procedures.

IIRC people ask that they should be able to send a mail to the bugtracker without the need for au­then­tic­a­tion. Per­son­ally I think the bugtrack­ing is­sue is in a state where we need to change our workflows/​procedures. It is con­veni­ent to get mails from the bugtracker and only have to reply to the mail to add some­thing. On the other hand, if I re­port bugs some­where, and if I really care about the prob­lem res­ol­u­tion, I am will­ing lo­gin to whatever in­ter­face to get this damn prob­lem solved.

Send­ing a prob­lem re­port from the sys­tem where I have the is­sue in an easy way is a very use­ful fea­ture. Cur­rently we have send-​pr for this and it uses emails. This means it re­quires a work­ing email setup. As an user I do not care if the tool uses email or HTTP or HTTPS, I just want to have an easy way to sub­mit the prob­lem. I would not mind if I first have to do a “send-​problem re­gister me@tld” (once), “send-​problem lo­gin me@tld” (once per system+user I want to send from) and then maybe a “send-​problem tem­plate write_template_here.txt” (to get some tem­plate text to fill out), edit the tem­plate file and then run “send-​problem send my_report.txt file1 file2 …”. That would be a dif­fer­ent work­flow, but still easy.

Email no­ti­fic­a­tions are surely needed, but if I really care about a prob­lem, I can be bothered to re­gister first. So in my opin­ion, we need a dif­fer­ent bugtracker des­per­ately enough that we need to drop our re­quire­ments re­gard­ing our cur­rent workflow/​procedures (even if it means we can not get a com­mand line way of sub­mit­ting bugs at all). The primary goal of the soft­ware needs to be to make it easy to track and re­solve bugs. The sub­mis­sion of bugs shall be not hard too. If I look at the state of the world as it is ATM, I would say a webin­ter­face with au­then­tic­a­tion is not a big bur­den to take if I really want to get my prob­lem fixed. Some com­mand line tool would be nice to have, but re­gard­ing the cur­rent state of our bugtracker it needs to be op­tional in­stead of a hard re­quire­ment.

Apart from mak­ing it easy to track and re­solve prob­lems, the soft­ware also needs to be able to make us aware of the biggest prob­lems. Now… you may ask what is a big prob­lem. Well… IMO it does not mat­ter to you what I think is big or small here. The per­son with a prob­lem needs to de­cide what is a big prob­lem to him. And people with the same prob­lem need to be able to tell that it is also a big prob­lem for them. So a fea­ture which al­lows to “vote” or “+1” or “AOL” (or how­ever you want to call it) would al­low to let users with prob­lems voice their opin­ion upon the rel­ev­ance of the prob­lem to our userbase. This also means there needs to be a way to see the highest voted prob­lems. An auto­matic mail would be best, but as above this is op­tional. If I as a de­veloper really care about this, I can be bothered to lo­gin to a webin­ter­face (or maybe someone vo­lun­teers to make a copy & paste and send a mail… we need to be will­ing to re­think our pro­ced­ures).

Get­ting patches more easy into a FreeBSD branch

It looks to me that this topic is re­quires a little bit more in­volve­ment from mul­tiple tools. In my opin­ion we need to switch to a dis­trib­uted ver­sion con­trol sys­tem. One which al­lows to eas­ily cre­ate my own branch of FreeBSD on my own hard­ware, and which al­lows to let other users use my branch eas­ily (if I want to al­low other to branch from my branch). It also needs to be able to let me push my changes to­wards FreeBSD. Ob­vi­ously not dir­ectly into the of­fi­cial sources, but into some kind of sta­ging area. Other people should be able to have a look at this sta­ging area and be able to re­view what I did. They need to be able to make some com­ments for oth­ers to see, or give some kind of (multi-dimensional?-)rating for the patch (code qual­ity /​ works for me /​ does not work /​ …). Based upon the review/​rating and maybe some auto­mated eval­u­ation (com­pile test /​ re­gres­sion test /​ bench­mark run) a com­mit­ter could push the patch into the of­fi­cial FreeBSD tree (ideal would be some auto­mated no­ti­fic­a­tion sys­tem, a push but­ton solu­tion for in­teg­ra­tion and so on, but as above we should not be afraid if we do not get all the bells and whistles).

If we would have some­thing like this in place, cre­at­ing some kind of long-​term-​release branch could be used more eas­ily in a col­ab­or­at­ive man­ner. Com­pan­ies which use the same long-​term-​release branch could sub­mit their back­ports of fixes/​features this way. They also could see if sim­ilar branches (there could be re­lated but dif­fer­ent branches, like 9.4–se­cur­ity–fixes-​only <= 9.4-official-errata-only <= 9.4-bugfixes <= 9.4-bugfixes-and-driverupdates <= …) could be merged to their in-​house branch (and maybe con­sequently push-​back to the of­fi­cial branch they branched from if the patch comes from a dif­fer­ent branch).

It does not mat­ter here if we would cre­ate a fixed set of branches for each re­lease, or if we only cre­ate some special-​purpose branches based upon the phase of the moon (ideally we would cre­ate a lot of branches for every re­lease, companies/​users can cherry pick/​submit what they want, and the status of a long-​term-​branch is solely based upon the in­flow of patches and not by what the se­cur­ity team or re­lease man­ager or a ran­dom de­veloper thinks it should be… but the real­ity will prob­ably be some­where in the middle).

I do not know if tools ex­ists to make all this hap­pen, or which tools could be put to­gether to make it hap­pen. I also did not men­tion on pur­pose tools I am aware of which already provide (small) parts of this. These are just some ideas to think about. In­ter­ested parties are in­vited to join the dis­cus­sion on hackers@ (which is far away from dis­cuss­ing spe­cific tools or fea­tures), but you are also free to add some com­ments here.
