[1.3beta12] Cannot downgrade

[Obiwarn]

After a brave

meteor update --release 1.3-beta.11

I wanted to downgrade with

meteor update --release 1.2.1

but got lots of errors:

Update to release METEOR@1.2.1 is impossible: 
While selecting package versions:             
error: Conflict: Constraint meteor@1.1.11-beta.11 is not satisfied by meteor 1.1.10.
Constraints on package "meteor":
* meteor@=1.1.10 <- top level
* meteor@1.1.0 <- iron:router 1.0.12
* meteor@1.1.7 <- underscore 1.0.4 <- accounts-base 1.2.2 <- service-configuration
1.0.5
* meteor@1.1.7 <- underscore 1.0.4 <- appcache 1.0.6
* meteor@1.1.10 <- reactive-dict 1.1.3 <- iron:controller 1.0.12 <- iron:router
1.0.12

... and so on.

Check your code out from source control. You shouldn't really be downgrading this way. That's what git is for.

@Obiwarn Hi, if you have a backup of your project, revert to your old version code.

Then you just need to downgrade the meteor. The easiest way is to reinstall meteor.
Check here: #6387

[Obiwarn]

Thank you @hongbo-miao.

So the update is global? I hoped that the meteor update is local, i.e. I can have different repos with different versions.

[hongbo-miao]

@Obiwarn yeah, it is global.
Because what updated for your project is just versions release packages files in your .meteor folder.

[benjamn]

@Obiwarn can you paste in the rest of the error output? All of the visible version constraints look ok for the downgrade…

I found this was an issue on other production apps too. Tested it with a skeleton app also. Removing .meteor/versions didn't help. Repro below:

$ meteor create --release 1.3-beta.12 downgrade-test
Created a new Meteor app in 'downgrade-test'. 

To run your new app:                          
  cd downgrade-test                           
  meteor                                      

If you are new to Meteor, try some of the learning resources here:
  https://www.meteor.com/learn

This project is at the latest release which is compatible with your current package constraints.

[huttonr]

I believe this is caused by standard-minifiers being split into standard-minifier-js and standard-minifier-css.

When you try to downgrade the packages remain but these demand beta versions.

CURRENT SOLUTION
Replace standard-minifier-js and standard-minifier-css with standard-minifiers in packages.

Then remove 1.3.0-split-minifiers-package from .finished-upgraders

You may also need to delete your versions file, but I've not tested omitting this.

Do a meteor update.

If needed, a meteor reset. (Warning: This will reset/delete your database and build cache.)

Would love an official fix in the meteor tool though for the 1.3 release.

[benjamn]

Looks like this is due to the standard-minifier-{js,css} changes, as @huttonr points out. Can we release those packages for 1.2.x, too, @stubailo?

[stubailo]

I don't think we have every done this before in the case of changing packages.

IMO the preferred way to downgrade should be to use version control or just back up the application before upgrading.

If we really want to publish them for old Meteor we can, but personally I wouldn't be excited about establishing the precedent that we expect downgrading to work, because that severely limits the transformations we can do inside the upgrade.

[huttonr]

Could upgraders as in `.finished-upgraders` not be used in reverse when downgrading? It is more a use case for beta testing as I don't believe many downgrade stable versions. And the problem is only caused by upgraders such as the minifiers split.

[stubailo]

Could upgraders as in .finished-upgraders not be used in reverse when downgrading?

If we wrote reliable reversible versions of every single one, then yes.

[Obiwarn]

@stubailo If it is one global Meteor version as @hongbo-miao said. What about enabling "per Project" Meteor versions?

[stubailo]

What about enabling "per Project" Meteor versions?

That's already the case. If you upgrade one app to Meteor 1.3 all of your other apps are unaffected and still run Meteor 1.2.
