[U-Boot-Users] RFC: U-Boot version numbering

[Wolfgang Denk]

Hello,

I would like to get your general opinion about  changing  the  U-Boot
version numbering scheme.

To be honest, I never really understood myself how this  is  supposed
to work and if the next version should be 1.3.4 or 1.4.0 or 2.0.0, i.
e.  which  changes  / additions are important enough to increment the
PATCHLEVEL or even VERSION number.

I therefor suggest to drop this style of version numbering and change
to a timestamp based version  number  system  which  has  been  quite
successfully  used  by  other  projects  (like  Ubuntu)  or  is under
discussion (for Linux).

My suggestion for the new version numbers is as follows:

VERSION = 1	(at least for the time being)

PATCHLEVEL = current year - 2000

SUBLEVEL = current month

Both PATCHLEVEL and SUBLEVEL shall always be 2 digits (at  least  for
the  next 91+ years to come) so listings for example on an FTP server
shall be in a sane sorting order.

If we accept this system, the next release which probably comes out
in October 2008 would be v1.08.10, and assuming the one after that
comes out in January 2009 would be named v1.09.01

Comments?

Best regards,

Wolfgang Denk

Real computer scientists despise the idea of actual  hardware.  Hard-
ware has limitations, software doesn't. It's a real shame that Turing
machines are so poor at I/O.

If we go to date based versions.  I'd prefer we keep year as 4 digits:

v1.2008.10
v1.2009.01

It just seems easier to me at a visual level when I look at try and  
compare versions.

I agree, although doing that makes the third field look like a month
to the uninitiated.  Perhaps use a letter like 'r' for revision
instead of a period for the second separator like so:

v1.2008r06

But it *is* a month...

v1.2008.06 would mean the June release in year 2008.

Just one thing: Verson numbering can be anything you want, but I think 
it should be self-consistent. And on that account, I realize that the 
"v1" part has no real meaning wrt to the rest of the version string, 
which date-related -- unless there is a plan to have simultaneous v1 and 
v2 releases, in which case it makes sense to have "v1".

Yes, in this case the meaning of 'v2' is "new version naming scheme", 
not "new software version".  It probably is superfluous.

A minor :) issue I can see is that there might be *some* confusion 
because of an apparent, numerical rollback from 1.3.4 back to 1.08.xx. 
You're bound to encounter some folks who will ask, again and again, why 
you're  working on 1.02.yy when 1.3.4 is out there.

Now an obvious solution would be to use 2 as the major number. If you're 
serious about not knowing when a major number bump-up is required, then 
you should be fairly ok with starting at 2.08.01 rather than 1.08.01. :)

Joke aside: you'll get questions *anyway*, and the scheme is as fine to 
me as it it.

Another, maybe trickier, issue is: you won't be able to cleanly number 
interim releases if you encounter a really serious bug right after 
you've produced this month's release, will you?

Good point. I have to admit that I was reading "1.08.xx" same as
1.8.xx; the leading 8 is just there to make sure that 1.08.xx sorts
before 1.10.xx.

Well, the "version 2" prefix is kind of already taken by Sascha Hauers
alternative implementation.

Should we go for 2.x.x anyway?

Well, we can always use EXTRAVERSION to add some additional name,  as
we do all the time for our -rc? prereleases.

May I suggest CC.YY.MM?

VERSION = <Century number>
PATCHLEVEL = <Year number>
SUBLEVEL =  <Month number>
EXTRAVERSION = <NULL> or <special purpose>

So this month's release number would become 20.08.08.

Why the extra dot after the century?  That looks like August 20th, 2008
in certain date formats.  And no ability to release more than once a
month?

Of course, we *could* base the version number on RFC 2550... :-)

All such date formats that list smaller units (days) before larger
units (months or years) such that they don't sort properly are
deprecated.

> And no ability to release more than once a month?

The EXTRAVERSION preprocessor symbol can be defined to allow a new
release every picosecond, or more often, if necessary.

> Of course, we *could* base the version number on RFC 2550... :-)

To solve the Y10K, Y100K, Y1M, ... problems, the "CC" in "CC.YY.MM"
shall be defined to be as long as necessary.

OK, reserving VERSION for <Century number> may not be such a good idea
after all.

Here's another suggestion that most may agree with:

VERSION =    <Year number  = 2008..10**30-1>
PATCHLEVEL = <Month number = 1..12>
SUBLEVEL =   <Day number   = 1..31>
EXTRAVERSION = <NULL> or <special purpose>

A release on the opening day of the Olympics would be:

2008.08.08

Perhaps the Version itself can be removed, there doesn't seems to be a 
point about it.
You can just do v2008.1. You can add a third field for the day for those 
really serious
bugs:)

That would be v2008.01, then, lest we want FTP sites to put november and 
december releases between january and february. :)

What, and not be able to crank out several releases in a single day? I 
vote for iso-8601 compliance (up to the second and including TZ).

Partially ack.
In principle, the version prefix is unnecessary, because year and month 
are clear. But it helps when sorting the version due to the existing 
"v1". For subversions I suggest a sequential number as suffix or an 
arbitrary string, e.g.:
v2.2008.10-001
v2.2008.10-rc2
v2.2008.10-projectX
v2.2008.10-experimental_091

Any opinions about upper case / lower case notation?

Kind regards,
Jens

Hi,
IMHO I think it is best to stick with the same version numbering scheme that you started with, even if it is not perfect. The alternative timestamp  scheme is not perfect either. You can probably find as many advantages for one as for the other, and the same goes for the disadvantages.

Even when using timestamp schemes, people often attach numerical version numbers when refering to some releases. That would probably the case for the U-Boot V2 that is currently under developement. That just adds up to the confusion.

Then in some time, maybe someone will propose to switch to a name based version scheme, and so on, and so on... :)

Well, obvious advantages of the timestamp based version number
include:

* It better matches our current development model, which is planning
  for a more or less fixed relese cycle (versus foir example feature
  based releases).

* It makes it much more easy to find out how old a version is. At the
  moment, if someone reports problems with version 1.1.2 you probably
  know that this is old stuff, but how old exactly? If the  name  was
  1.04.04  you  would  have  seen immediately that this was a version
  from April 2004, and this is *really* old.

Wolfgang Denk

[U-Boot-Users] 1.3.4-rc2 autoboot timeout - MPC8548

[Zach Sadecki]

Autoboot timeout in 1.3.4-rc2 prints incorrectly on my system.

We have a system based closely off of the mpc8548cds system.  Prior 
builds (1.3.4-rc1) didn't have this problem.  Now during boot, the 
autoboot announcement is incorrect.  It is set for 1 second and actually 
works in 1 second, but the printed statement is wrong.  It says, 
"Autoboot in 2146991868 seconds..."

Any ideas for me?

Thanks,
Zach

That's the price you have to pay  for  maintaining  an  out  of  tree
version. If your code had been merged into mainline, it would have
continued to work, I bet.

I guess (and I can only guess, as you did not  provide  any  relevant
information)  that  you  might  be  using  the CONFIG_AUTOBOOT_PROMPT
feature in your config file, and that you  did  not  fix  your  board
config file afterpulling in the latest versions.

Please see the (changed) description of CONFIG_AUTOBOOT_PROMPT in the
README, and check what commit c37207d7 is  doing;  then  implement  a
similar change in your board config file.

Best regards,

Wolfgang Denk

Lots of folks confuse bad management with destiny.   -- Frank Hubbard

[U-Boot-Users] RFC: U-Boot version numbering

[Adrian Filipi]

Like a lot of others, I think v1.08.xx will be confusing alongside the existing 
1.x.y releases.

As to the v1/v2 issues, the problem is that it's just a number and a greater 
number implies progress and a unidirectional relationship.  Given that v2 
already exists concurrent with v1, it's misleading.  People won't know that one 
might not be for production.

Instead of v1/v2, I'd prefer that the first field be related to the version 
control branch name.  i.e. u-boot-stable-yyyy.mm for the master git branch and 
maybe u-boot-experimental-yyyy.mm, should there ever be concurrent releases.

[U-Boot-Users] RFC: U-Boot version numbering

[Matthias Fuchs]

Hi,

in general I totally ack to a new version numbering scheme.

When we are releasing U-Boot for some of our hardware this is typically done
asynchronous to the U-Boot release cycle. We (often) cannot wait until a new
U-Boot is released. So we take the current U-Boot version + build date/time
as effective version.

We also used CONFIG_IDENT_STRING to identify a special version some time ago.
But I do not like it much.

Do you see a better way to identify a special U-Boot version?
EXTRAVERSION could be fine, but it is already used to release candidates etc.

What is common practice in other companies?

Matthias
