What if change the name `main' to other fs name like `other',
create new `main' on some other fossil partition (could be a 1MB
file on kfs), change /active/adm/users on `other'?

An approach like that should also work. There's no need to
have a filesystem "main", just boot and use "other" directly.
Having a filesystem "main" just introduces some shortcuts
for the common attaches and, as we now know, an automatic
read on the users file.

[9fans] duplicate uid in fossil

[Kenji Arisawa]

Hello,

I'm stupid enough to add a user that is already registered in fossil.
The result is:

hera# fossil/fossil -c '. '$v/flproto
nuser 4
diskThread 782
fs->ehi 4789 fs->elo 1 active=76750
got fs source
got file root
nuser 28
duplicate uid 'alice'
assert failed: box->nuser == nuser
fossil 777: suicide: sys: trap: fault read addr=0x0 pc=0x0002a89f

How can I remove duplicate uid?

Re: [9fans] duplicate uid in fossil

[andrey mirtchovski]

do you have a venti to restore from? or scores from fossil snapshots?

by the way, fossil-related man pages don't appear on the web at the moment
(http://plan9.bell-labs.com/sys/man/index.html) but i think it may be
possible to reset the user groups with '-d'(?).. or somesuch argument to
fossil. sorry, no access to a plan9 installation to verify right now.

Hello,

Thanks, but it seems '-d' is no help because:
	Users -r /active/adm/users is automatically executed when
           the file system main is opened.
and then suicide.

I think duplicate lines in adm/users should be ignored by fossil.

Re: [9fans] duplicate uid in fossil

[jmk]

If you can recompile fossil somewhere, then just take that assert out.
The code for reading the users file strips out duplicates so only the first
instance will be used. Once the system is up you will have to write the
file back out with 'users -w' to permanently remove the duplicate. The
decision to automatically read the users file on opening main was arguably
wrong.

However, you are not supposed to be able to create duplicate entries
if you use the console commands - how did you do it?

That's curious (no offence intended).  You'd think duplication would
be easy to spot, but perhaps you have a large number of users?  In
which case, can I recommend that you keep the file sorted, at least
below the default users?  It will make spotting duplications a whole
lot easier.  And with the new string identifiers instead of numeric
ones, it is less jarring to the eye.

fossil keeps the file sorted (look at /adm/users on sources).

Not at all.  You made a mistake and it may be beneficial for others to
avoid making the same mistake.  Hence my curiosity.  It could easily
have happened to anyone else (I have a single user of my system, so
I'm an unlikely one, at least in the foreseeable future).

To be honest, I would not have figured out a solution, so I'm pleased
you raised the flag in the first place.
