[1.8.2] ValueError: dictionary update sequence element #0 has length 1; 2 is required

[Maxime Chambreuil (http://www.savoirfairelinux.com)]

Using the 1.8.2 recipe and OpenERP trunk branches, I am getting this error message building out :

Hi Maxime,

you most probably have a syntax problem in the 'addons' option. Maybe a missing destination directory or wished revision.
The recipe should catch an reraise this as a UserError.

[Maxime Chambreuil (http://www.savoirfairelinux.com) (max3903)]

Here is my addons options. It works with version 1.7.3 of the recipe.

addons = bzr lp:openerp-web ../../../bzr/web last:1 subdir=addons
         bzr lp:openobject-addons ../../../bzr/addons last:1
         # bzr lp:openerp-canada/8.0 ../../../bzr/canada last:1
         local ../addons

Hi Maxime

Can you test without the comment line

[Georges Racinet (gracinet)]

Thanks for the excerpt, I could reproduce this in the unit test I'm writting for the UserError rewrapping.

The culprit is the commented out line : one may not comment with a dash within an option (the whole is considered by buildout as a single line, hence this dash is not considered to be at the beginning of the line, which is in turn the only allowed case of dash commenting)

This is a common enough annoyance that I'm considering implementing the dash leading comments for this option. But that would create ambiguity for the other ones. There's already something similar in the 'revisions' option (semicolon end-of-line comments are directly supported)

[Maxime Chambreuil (http://www.savoirfairelinux.com) (max3903)]

I moved the dash to the start of the line and it is working now.

Thank you very much Georges.

Have a great day.

[Georges Racinet (gracinet)]

That was not really a bug. Still, a change has been done so that these kind of syntax problems don't look as bugs (now it's UserError).
