Merge lp:~akretion-team/partner-contact-management/base-location-geonames-import into lp:~partner-contact-core-editors/partner-contact-management/7.0

[Alexis de Lattre]

Add module base_location_geonames_import ; this module adds a wizard to import better zip entries from Geonames (http://download.geonames.org/export/zip/).

Nicolas Bessi suggested on twitter that it should be part of the geospacial addons. But, after thinking about it, my opinion is that this module would be better here, because users of the "base_location" module would have a higher chance of finding this module here than in the geospacial addons.

Allow to skip entries in the _prepare method.

Hello thanks for the patch.

Is there a good reason not to merge it here: https://launchpad.net/geospatial-addons ?
Some tests would also be a nice addition.

@Nicolas

As I said in my comment, I think that it's better for the module "base_location_geonames_import" to sit right next to the "base_location" module, so that it's easier to find for users of the "base_location" module. We could even imagine that the wizard that is provided by "base_location_geonames_import" could be provided inside "base_location" and not in a separate module.

[Nicolas Bessi - Camptocamp (nbessi-c2c-deactivatedaccount)]

Oups I missed that.

Actually, I do not agrees with you, but I won't argue too long on this as for me the branch organisation problem is more deep. Let's see what other think about it.

Some comments Belows:
Some PEP8 in manifest:

328 + _("The content of the file doesn't correspond to the "
329 + "selected country."))

I will add row value and country info it will be more easy for support.

A question with :
+ if res_request.status_code != requests.codes.ok:
349 + raise orm.except_orm(
350 + _('Error:'),
351 + _('Got an error %d when trying to download the file %s.')
352 + % (res_request.status_code, url))

It's been a long time since I used geonames, if I'm correct in case of wrong country it returns 404 that right. If it the case I'm ok with this else we may have to treat a 200 with a message

+ if bzip_ids_to_delete:
356 + bzip_obj.unlink(cr, uid, bzip_ids_to_delete, context=context)
357 + logger.info(
358 + '%d better zip entries deleted for country %s'
359 + % (len(bzip_ids_to_delete), wizard.country_id.name))

This is a quite a direct approach, I agree create, update, unactivate is quite not easy to put in place, but as other development can depends on base location model there should at least be a Big warning in manifest.

Also it would be a good idea to add a small lock to ensure atomicity during the import.
A query "for update no wait" a the begining of transaction would be nice.

Tests are also missing. Without depending on the geoname services having a local excrept to base the tests would be great.

Thanks for the contributions, keep up the good work.

Regards

Nicolas

Insist on the fact that the wizard deletes current better zip entries in the module description and in the wizard itself.
Better error message when the country code inside the file is wrong.

42. By Alexis de Lattre on 2014-04-11

Add a FOR UPDATE NOWAIT at the beginning of the transaction.

[Alexis de Lattre (alexis-via)]

@Nicolas:

I confirm that it returns 404 if you try to download a wrong country.

I have taken into account your other remarks in my last commits (unless the tests ; I don't have experience in this). I am not sure I fully understand the benefit of the FOR UPDATE NOWAIT in this particular case... at least I hope I implemented it as you wanted.

[Nicolas Bessi - Camptocamp (nbessi-c2c-deactivatedaccount)]

Hello,

Thank for the fixes.
The "UPDATE NO WAIT" will lock the selected rows at postgres database level.
It will avoid a process using the base_location data to alter flushed entries.
It will also avoiding having many concurrent instance of the wizard running on the same rows.
In this case I wonder if we may not want to put a lock on the whole table has we add new entries.

For the test I will see ifI can provide some but I'm in holiday next week, so it have to wait a little.

Regards

Nicolas

[MERGE] merge with trunk revno 40.

[Lorenzo Battistini (elbati)]

Hello Alexis, many thanks for the module.

What do you think about creating the res.country.state records if they don't exist, before mapping them in the 'states' dictionary?

The current version is supposed to correctly work with states if you first create states data by modules like l10n_fr_state.
But if base_location_geonames_import also imported states data from geonames (creating records if they don't exist yet) we would not need an extra module just to create states data.
