[REF] product: Set max iterations to look for product combinations

[moylop260]

Sometimes the products are stuck for a long time looking for combinations

This patch set max iterations for this infinite loop

It is reproduced with the following script

self.env.cr.execute("""
    SELECT ptal.product_tmpl_id,
        ARRAY_AGG(ptav.id) AS ptav2del
    FROM product_template_attribute_line AS ptal
    JOIN product_attribute AS pa
      ON ptal.attribute_id = pa.id
    JOIN product_template_attribute_value AS ptav
      ON ptal.id = ptav.attribute_line_id
    WHERE pa.create_variant = 'always'
      AND ptav.id IS NOT NULL
      AND ptal.active IS TRUE
    GROUP BY ptal.product_tmpl_id
""")
res = self.env.cr.fetchall()

for r in res:
    product_tmpl = self.env["product.template"].browse(r[0])
    product_templ_attr_vals = self.env["product.template.attribute.value"].browse(r[1])
    product_templ_attr_vals.unlink()
    print(product_tmpl)
    combination = product_tmpl._get_first_possible_combination()

Maybe this could be a fix to Odoo.

Maybe this could be a fix to Odoo.

I thought that, too

However, we need to justify it very well, and the current way to reproduce it is by deleting the product_template_attribute_value records and it is not reproduced functionally

The first impression looks like a migration issue for this database not reproducible from Odoo itself

But we keep checking...

BTW could you check the migration script used for this case, please?

What about ese similar technique than the dynamic_variant_limit?

odoo/addons/product/models/product_template.py

Line 783 in 8a64fdd

variant_limit = self.env['ir.config_parameter'].sudo().get_param('product.dynamic_variant_limit', 1000)
