- Step 3 (Enable ACME on Cluster) now shows a process icon instead of a misleading green checkmark when ACME is enabled but not yet applied. Per-cluster "(pending apply)" annotation for multi-cluster setups. - Step 4 button and all /apply-management navigation buttons now say "Apply Changes" instead of "Configure" for clearer guidance. - Setup Guide auto-selects the correct cluster before navigating to Apply Management, showing pending cluster names in alerts. - Pending ACME disable changes are now correctly detected in Step 4 even when acme_enabled is already FALSE in the database. - Entity snapshot rollback for cluster ACME settings: reject correctly restores acme_enabled/acme_backend_url to pre-change values. - Deduplication logic prevents "last wins" bug when multiple ACME toggles are rejected in sequence. - Connection leak prevention with try/finally around conn2 in ACME config version creation. - Step 4 branching uses boolean has_enabled instead of fragile string truthiness check.

Entity Snapshot Module for HAProxy OpenManager
|
||
|
||
Bu modül, entity değişikliklerinin snapshot'ını alır ve reject edildiğinde
|
||
geri yüklenmesini sağlar.
|
||
|
||
Usage:
|
||
# UPDATE için snapshot al
|
||
old_entity = await conn.fetchrow("SELECT * FROM frontends WHERE id = 5")
|
||
snapshot_metadata = await save_entity_snapshot(
|
||
conn=conn,
|
||
entity_type="frontend",
|
||
entity_id=5,
|
||
old_values=old_entity,
|
||
new_values={"bind_port": 443},
|
||
operation="UPDATE"
|
||
)
|
||
|
||
# Config version'a ekle
|
||
await conn.execute(
|
||
"INSERT INTO config_versions (..., metadata) VALUES (..., $1)",
|
||
json.dumps(snapshot_metadata)
|
||
)
|
||
|
||
# Reject edildiğinde rollback yap
|
||
await rollback_entity_from_snapshot(conn, snapshot_metadata["entity_snapshot"])
|
||
|
||
Supported Operations:
|
||
- UPDATE: Var olan entity'nin field'larını eski değerlere döndür
|
||
- CREATE: Yeni oluşturulan entity'yi sil (bulk import için)
|
||
- UPDATE_RESTORE: Restore işlemi sırasında yapılan UPDATE'i geri al
|
||
|
||
Feature Flag:
|
||
ENTITY_SNAPSHOT_ENABLED=true|false
|
||
Default: false (güvenli başlangıç)
