Interner Serverfehler bei der Verwendung bestimmter Tags (FEHLER: doppelter Schlüsselwert verstößt gegen die eindeutige Einschränkung „index_tags_on_name")

Beitragen Fehler
1

This seems to be an odd problem as it is only effecting some tags - when trying to create a Topic with the tag the user is shown an Internal Server Message. Sometimes, when it gets past that stage, we are shown the same message via the review queue system. When going to the pages of these affected tags, it says Oops! That page doesn’t exist or is private.

Here are some logs:

ActiveRecord::RecordNotUnique (PG::UniqueViolation: ERROR:  duplicate key value violates unique constraint "index_tags_on_name"
DETAIL:  Key (name)=(ecommerce) already exists.

Any idea why it’s happening? It seems to be trying to create a tag that already exists?

Update:

On one of the tags where we were getting the same problem, we ended up simply asking the user to repost without the tag, then upon editing it I was able to add the tag (and also visit the tag’s page without issue). Previously the user was actually able to post the topic but it had gone into the review queue (as we review all first posts/topics) and we were getting the internal server error when trying to authorise the topic.

However, I’m not able to add the other tag that it happened to (ecommerce) as it is still reporting an internal server error.

Das gleiche Problem tritt bei einem anderen Tag auf:

ActiveRecord::RecordNotUnique (PG::UniqueViolation: ERROR:  duplicate key value violates unique constraint "index_tags_on_name"
DETAIL:  Key (name)=(file-uploading) already exists.
)
/var/www/discourse/vendor/bundle/ruby/2.6.0/gems/rack-mini-profiler-1.1.2/lib/patches/db/pg.rb:72:in `async_exec_params'

Ist das ein Fehler in Discourse oder bei AR/Rails? Es scheint, als würde versucht, den Tag erneut zu erstellen, obwohl er bereits existiert?

Kannst du im Data Explorer in der Tags-Tabelle nachschauen? Vielleicht gibt es ein Problem mit der Groß- und Kleinschreibung von Ecommerce im Vergleich zu ecommerce?

Hallo Sam, ich habe in der Tabelle nachgeschaut und dort sind:

ecommerce
e-commerce

Bei der zweiten (file-uploading) gibt es:

file-downloading
file-uploading

Beide haben Bindestriche, ich frage mich also, ob das das Problem ist?

In den Einstellungen haben wir „Tags in Kleinbuchstaben erzwingen

5

Nicht zu 100 % sicher, warte einen Tag oder so, @neil kennt sich mit dem Tag-System sehr gut aus und hat vielleicht einige Ideen dazu.

Wird gemacht, danke Sam :smiley:

Ich habe mit gemischten Groß-/Kleinschreibungen bei Tag-Namen und Tags mit Bindestrichen gespielt, konnte diesen Fehler jedoch nicht reproduzieren. Welche genaue Version von Discourse verwendest du? Tritt dies in einer Kategorie mit Tag-Einschränkungen auf? Welche weiteren Tag-Einstellungen nutzt du?

2 „Gefällt mir“

Hallo Neil, ich verwende 2.4.0.beta6 (8ca5aad1e2)

Ich habe das Problem gelöst, indem ich die Tags manuell in der Rails-Konsole umbenannt habe. Interessanterweise lieferte das Tag e.commerce nil zurück, obwohl es existierte! Ich habe es per ID gefunden, es dann umbenannt, und jetzt funktioniert es auch.

Ich habe das Gefühl, dass dies begann, als die Groß-/Kleinschreibung eingeführt wurde (wir hatten das Problem schon eine Weile, aber ich warte normalerweise ein paar neue Releases ab, da du Dinge in der Regel ziemlich schnell reparierst).

Wenn du möchtest, dass ich noch etwas weiter untersuche, lass es mich wissen. Andernfalls werde ich alle Tags (oder Fehlerprotokolle) durchgehen, andere defekte Tags identifizieren und diese entsprechend reparieren. Falls es hilfreich ist, hier sind die Antworten auf deine Fragen:

Nein – aber alle Kategorien erfordern mindestens ein Tag.

Ich habe tag-name in tag-name2 umbenannt und dann wieder zurück in tag-name.

Ich habe die Suche nach Name verwendet, um sie zu finden:

Tag.find_by name: "tag-name"

Das hat jedoch bei e-commerce nicht funktioniert. Ich musste es nach ID finden, was seltsam erscheint – ich bin mir nicht sicher, warum das passiert ist.

Das Einzige, was mir noch einfällt, ist, dass ich zu einem bestimmten Zeitpunkt Threads „massenhaft

Entschuldigung @neil, ich bin auf ein weiteres Problem gestoßen, das damit zusammenhängen könnte.

Zwei Tags mit demselben Namen, aber meine manuelle Lösung funktioniert diesmal nicht.

[1] pry(main)> Tag.find_by(name: "liveview")

[7] pry(main)> t.save

=> "liveview"
[9] pry(main)> t.save
=> true
[10] pry(main)> t.name = "liveview1"

[11] pry(main)>

liveview2 funktioniert, aber das einzelne liveview nicht. Allerdings funktioniert es, wenn es liveview1 heißt, doch wenn der Name wieder in liveview geändert wird, erscheint nur noch Oops! That page doesn’t exist or is private.. Liegt das am Index?

(auch nichts in /logs)

Es gibt zwei Indizes, um diesen Fall abzusichern. Fehlen in Ihrer Datenbank diese Indizes?

Eine Migration vom 28. September 2018 sollte Tags mit doppelten Namen bereinigt und anschließend einen der Indizes erstellt haben. Haben Sie Ihre Website von anderer Forum-Software importiert? Falls ja, könnten dabei doppelte Zeilen entstanden sein, wodurch die Erstellung der Indizes fehlgeschlagen ist.

Nein, dies war schon immer ein Discourse-Forum. Das Einzige, was ich getan habe, war der Wechsel auf einen anderen Server, was eine Neuinstallation und anschließenden Import über ein Backup bedeutete. Ich denke, das wurde im August letzten Jahres durchgeführt – könnte das die Ursache sein?

Sollte ich etwas wie REINDEX TABLE tags; ausführen, um die Indizes neu zu erstellen, Neil?

Edit: Mir ist gerade aufgefallen, dass created_at und updated_at keinen Eintrag not null unter „Nicht null

14

Ja, ich denke, dass eine Neuindizierung der Tabelle erforderlich ist. Aber zuerst müssen Sie die Tags mit doppelten Namen umbenennen, sonst schlägt die Neuindizierung fehl. Und hoffen, dass nur die Tags-Tabelle dieses Problem hat…

Ich sehe nicht, wie eine Wiederherstellung dieses Problem verursachen könnte. Die Indizes sind vorhanden, funktionieren aber offensichtlich nicht.

Ok, erledigt :smiley:

Falls jemand sonst die Abfrage benötigt, um doppelte Tags zu finden, lautet sie:

SELECT name, COUNT(*)
FROM tags
GROUP BY name
HAVING COUNT(*) > 1

Neil, erschreck mich jetzt nicht! :scream:

Ich habe mir die Tabelle categories kurz angesehen, und die scheint in Ordnung zu sein (es gibt zwar einige doppelte Einträge basierend auf dem Namen, aber es handelt sich um Unter-Kategorien).

Danke für eure Hilfe @sam und @neil :blush:

(Die Neuindizierung hatte übrigens keine Auswirkung auf dieses Problem, Neil)

Wir haben diesen Index:

Bist du zu 100 % sicher, dass er in der Tabelle existiert? Denn das, was du beschreibst, wäre ein völlig defektes PostgreSQL, was unendlich unwahrscheinlich ist. Das würde Wellen der Erschütterung durch die gesamte Community schicken.

Viel wahrscheinlicher ist, dass dieser Index irgendwann durch menschliches Versagen gelöscht wurde …

Als Minimum empfehle ich dir create unique index on tags (name), aber was könnte sonst noch fehlen?

Hallo Sam,

ich habe:

discourse=> \d tags
                                          Table "public.tags"
     Column     |            Type             | Collation | Nullable |             Default              
----------------+-----------------------------+-----------+----------+----------------------------------
 id             | integer                     |           | not null | nextval('tags_id_seq'::regclass)
 name           | character varying           |           | not null | 
 topic_count    | integer                     |           | not null | 0
 created_at     | timestamp without time zone |           |          | 
 updated_at     | timestamp without time zone |           |          | 
 pm_topic_count | integer                     |           | not null | 0
Indexes:
    "tags_pkey" PRIMARY KEY, btree (id)
    "index_tags_on_lower_name" UNIQUE, btree (lower(name::text))
    "index_tags_on_name" UNIQUE, btree (name)

Und um die Indizes neu zu erstellen, habe ich:

  • doppelte Tags umbenannt (also tag_name_1 und tag_name_2 usw.)
  • überprüft, dass mit der Abfrage im vorherigen Beitrag keine weiteren doppelten Tags mehr vorhanden sind
  • zu rails db gewechselt und dann ausgeführt:
discourse=> REINDEX TABLE tags;
REINDEX

Muss ich neben dem noch etwas anderes tun, Sam?

Vielleicht versuchst du, einen Duplikat-Tag einzufügen und zu prüfen, ob dein Index zufrieden ist und keine Duplikate mehr zulässt?

Sieht gut aus, Sam:

[1] pry(main)> t=Tag.new
=> #<Tag:0x000055fe76499830 id: nil, name: nil, topic_count: 0, created_at: nil, updated_at: nil, pm_topic_count: 0>
[2] pry(main)> t
=> #<Tag:0x000055fe76499830 id: nil, name: nil, topic_count: 0, created_at: nil, updated_at: nil, pm_topic_count: 0>
[3] pry(main)> t.name ="test-five"
=> "test-five"
[4] pry(main)> t.save
=> true

[5] pry(main)> Tag.last
=> #<Tag:0x000055fe7671ce90
 id: 1995,
 name: "test-five",
 topic_count: 0,
 created_at: Fri, 08 Nov 2019 02:44:36 UTC +00:00,
 updated_at: Fri, 08 Nov 2019 02:44:36 UTC +00:00,
 pm_topic_count: 0

[6] pry(main)> t=Tag.new
=> #<Tag:0x000055fe76763a70 id: nil, name: nil, topic_count: 0, created_at: nil, updated_at: nil, pm_topic_count: 0>
[7] pry(main)> t.name ="test-five"
=> "test-five"
[8] pry(main)> t.save
=> false
[9] pry(main)>

Habe es auch über das Forum in einem Topic versucht:

Wenn du denkst, dass ich noch etwas anderes ausprobieren sollte, lass es mich bitte wissen :smiley:

Zur Bestätigung: Ich habe über die Konsole nichts Weiteres mit der Datenbank gemacht, daher bin ich mir nicht sicher, warum das passiert ist. Ich -glaube-, es könnte nach der Einführung der Groß-/Kleinschreibung begonnen haben, kann das aber nicht sicher sagen. Wenn du möchtest, dass ich noch etwas anderes überprüfe, um die Ursache des Problems zu ermitteln, lass es mich einfach wissen, Sam.
