Aggiornamento fallito con errore "duplicate key value violates unique constraint"

morevnaproject · 27 Febbraio 2020, 10:54am

Hi!

Today I tried to upgrade my Discourse instance from “2.1.0.beta6” to latest one - “2.5.0.beta1”.

But web upgrade failed in the middle and after that my server displayed recommendation to update by executing ./launcher rebuild app.

I did that, but upgrade failed with error:

root@cloud:/var/discourse# ./launcher rebuild synfig-forums

./discourse-doctor may help diagnose the problem.

Note: I am intentionally used ./launcher rebuild synfig-forums command, because my instance is described in synfig-forums.yml file, not app.yml.

As I understand, the problem described by this line:

DETAIL:  Key (poll_id, digest)=(30, 399fc6670871474cd7ce0458401fd299) already exists.

What can I do in this situation? Any assistance is much appreciated!

morevnaproject · 27 Febbraio 2020, 1:32pm

Okay, volevo esaminare il contenuto del database, quindi ho eseguito le seguenti operazioni:

cd /var/discourse
./launcher start synfig-forums
./launcher enter synfig-forums
su - postgres
psql

Ho ricevuto un errore:

psql: impossibile connettersi al server: Nessuno di tali file o directory
	Il server è in esecuzione localmente e accetta
	connessioni sul socket di dominio Unix "/var/run/postgresql/.s.PGSQL.5432"?

pfaffman · 27 Febbraio 2020, 1:38pm

Hai un indice danneggiato. Consulta Can't restore due to corrupt indexes (with some clues on how to deal with corrupt indexes) per alcuni suggerimenti.

Hai un contenitore del database separato? Immagino di sì e che tu debba accedere a quel contenitore invece.

morevnaproject · 27 Febbraio 2020, 1:39pm

Grazie per i suggerimenti!

No, ho un’installazione con contenitore autonomo (immagino sia così che si chiami).

Ho provato ad avviare il servizio postgresql (dal contenitore docker) e ho ottenuto quanto segue:

root@cloud-synfig-forums:/var/www/discourse# service postgresql start
 * Starting PostgreSQL 10 database server                                        * Error: Config owner (postgres:107) and data owner (syslog:106) do not match, and config owner is not root
                                                                         [fail]

morevnaproject · 27 Febbraio 2020, 1:47pm

Ok, sono riuscito ad avviare il servizio PostgreSQL, ho eseguito il backup del database ed è entrato nel database:

# chown -R postgres /shared/postgres_data
# service postgresql start
 * Starting PostgreSQL 10 database server                                                                                        [ OK ]

# su - postgres
$ psql discourse
psql (10.4 (Ubuntu 10.4-2.pgdg16.04+1))
Type "help" for help.

discourse=#

Ora, cosa posso fare per ripristinare la mia installazione?

pfaffman · 27 Febbraio 2020, 1:48pm

Non sembra una buona notizia.

Quando hai eseguito la ricostruzione, ha menzionato qualcosa riguardo all’aggiornamento di PostgreSQL? L’hai eseguita più di una volta?

Hai un backup recente? Potrebbe essere più semplice provare a ripristinarlo da quello, ma sarà comunque difficile.

morevnaproject · 27 Febbraio 2020, 1:57pm

Non me lo ricordo. C’erano troppi messaggi mentre stavo aggiornando tramite l’interfaccia web.

Sì, ho eseguito l’aggiornamento più di una volta: la prima volta dall’interfaccia web (è fallito), poi dalla riga di comando (più volte).

Sì, ho un backup creato 24 ore fa. Posso ripristinarlo, ma perderò alcuni messaggi (quelli pubblicati dopo il backup).

Falco · 27 Febbraio 2020, 2:43pm

Non si tratta di un indice corrotto.

Tra la versione 2.1 e la 2.5, abbiamo spostato i pool da PluginStore a tabelle dedicate. Uno dei motivi di questo spostamento è garantire la coerenza dei dati, che è esattamente il problema che stai riscontrando.

Hai un valore duplicato nella tabella poll_options. Puoi andare lì ed eliminare le voci duplicate?

morevnaproject · 27 Febbraio 2020, 2:46pm

Grazie per il chiarimento!
Non sono un esperto di PostgreSQL… puoi aiutarmi con i comandi necessari da eseguire? (considerando che sono già dentro psql).

morevnaproject · 27 Febbraio 2020, 4:03pm

Ok, ho eseguito questo:

discourse=# SELECT * FROM poll_options;
 id | poll_id | digest | html | anonymous_votes | created_at | updated_at 
----+---------+--------+------+-----------------+------------+------------
(0 rows)

Come è possibile che questa tabella sia vuota?

Le altre tabelle non sono vuote:

discourse=# SELECT name FROM badges WHERE id = 13;
    name    
------------
 First Flag
(1 row)

morevnaproject · 27 Febbraio 2020, 4:09pm

Sospetto che la voce duplicata provenga da Plugin Store. Ma dove si trova e come posso visualizzarla/modificarla?

RGJ · 27 Febbraio 2020, 4:47pm

È solo un’altra tabella (plugin_store_rows).

Falco · 27 Febbraio 2020, 4:59pm

Sembra che i voti del sondaggio siano effettivamente nella tabella post_custom_fields, dove la colonna name è ‘polls’.

RGJ · 27 Febbraio 2020, 5:46pm

Ciò è stato modificato da questo commit e la migrazione corrispondente popola la tabella poll_options. Quindi potrebbe essere in corso un tentativo di inserire un record duplicato.

https://github.com/discourse/discourse/blob/master/plugins/poll/db/post_migrate/20180820080623_migrate_polls_data.rb#L132-L138

morevnaproject · 28 Febbraio 2020, 6:29am

Quindi, vedo due opzioni per me:

Rimuovere tutti i dati dei sondaggi dal mio database ed eseguire di nuovo il processo di aggiornamento. In questo modo perderò tutti i sondaggi, ma va bene così.
Modificare il codice di migrate_polls_data.rb in modo che salti l’inserimento di voci duplicate. Soluzione migliore, ma non so come farlo.

morevnaproject · 28 Febbraio 2020, 6:49am

Come posso modificare il codice per permettere a questa parte di fallire silenziosamente?

morevnaproject · 28 Febbraio 2020, 6:57am

Ok, penso che sia sufficiente modificare l’istruzione SQL aggiungendo ON CONFLICT DO NOTHING - https://stackoverflow.com/a/31742830
Funzionerebbe?

Ok, ho eseguito quanto segue da pgsql:

SELECT *
	FROM post_custom_fields
	WHERE name = 'polls'
	AND value LIKE '%399fc6670871474cd7ce0458401fd299%';

Mi ha restituito una riga. Quindi l’ho rimossa:

DELETE FROM post_custom_fields
	WHERE name = 'polls'
	AND value LIKE '%399fc6670871474cd7ce0458401fd299%';

Nota: il modo corretto sarebbe stato eliminare tramite l’ID della riga, ma dato che era stata restituita una sola riga, ho fatto così.

Dopo di ciò ho riavviato l’aggiornamento ed è andato a buon fine. Grazie a tutti quelli che hanno condiviso i loro suggerimenti!
