### Motivation

- The task `trim ledgers` runs in the thread `BkMainThreadPool.choose(ledgerName)`
- The task `write entries to BK` runs in the thread `BkMainThreadPool.choose(ledgerId)`

So the two tasks above may run concurrently/

The task `trim ledgers` work as the flow below:
- find the ledgers which are no longer to read, the result is `{Ledgers before the slowest read}`.
- check if the `{Ledgers before the slowest read}` is out of retention policy, the result is `{Ledgers to be deleted}`.
  - if the create time of the ledger is lower than the earliest retention time, mark it should be deleted
  - if after deleting this ledger, the rest ledgers are still larger than the retention size, mark it should be deleted
- delete the`{Ledgers to be deleted}`

**(Highlight)** There is a scenario that causes the task `trim ledgers` did  discontinuous ledger deletion, resulting consume messages discontinuous:
- context:
  - ledgers: `[{id=1, size=100}, {id=2,size=100}]`
  - retention size: 150
  - no cursor there
- Check `ledger 1`, skip by retention check `(200 - 100) < 150`
- One in-flight writing is finished, the `calculateTotalSizeWrited()` would return `300` now.
- Check `ledger 2`, retention check `(300 - 100) > 150`, mark the ledger-2 should be deleted.
- Delete the `ledger 2`.
- Create a new consumer. It will receive messages from `[ledger-1, ledegr-3]`, but the `ledger-2` will be skipped.

### Modifications

Once the retention constraint has been met, break the loop.

…pache#21035)

Motivation: After [PIP-118: reconnect broker when ZooKeeper session expires](apache#13341), the Broker will not shut down after losing the connection of the local metadata store in the default configuration. However, before the ZK client is reconnected, the events of BK online and offline are lost, resulting in incorrect BK info in the memory. You can reproduce the issue by the test `BkEnsemblesChaosTest. testBookieInfoIsCorrectEvenIfLostNotificationDueToZKClientReconnect`(90% probability of reproduce of the issue, run it again if the issue does not occur)

Modifications: Refresh BK info in memory after the ZK client is reconnected.

…ed on topic, when dedup is enabled and no producer is there (apache#20951)

(cherry picked from commit 30073db)
(cherry picked from commit f68589e)
…ata when doing lookup (apache#21063)

Motivation: If we set `allowAutoTopicCreationType` to `PARTITIONED`, the flow of the create topic progress is like the below:
1. `Client-side`: Lookup topic to get partitioned topic metadata to create a producer.
1. `Broker-side`: Create partitioned topic metadata.
1. `Broker-side`: response `{"partitions":3}`.
1. `Client-side`: Create separate connections for each partition of the topic.
1. `Broker-side`: Receive 3 connect requests and create 3 partition-topics.

In the `step 2` above, the flow of the progress is like the below:
1. Check the policy of topic auto-creation( the policy is `{allowAutoTopicCreationType=PARTITIONED, defaultNumPartitions=3}` )
1. Check the partitioned topic metadata already exists.
1. Try to create the partitioned topic metadata if it does not exist.
1. If created failed by the partitioned topic metadata already exists( maybe another broker is also creating now), read partitioned topic metadata from the metadata store and respond to the client.

There is a race condition that makes the client get non-partitioned metadata of the topic:
| time | `broker-1` | `broker-2` |
| --- | --- | --- |
| 1 | get policy: `PARTITIONED, 3` | get policy: `PARTITIONED, 3` |
| 2 | check the partitioned topic metadata already exists | Check the partitioned topic metadata already exists |
| 3 | Partitioned topic metadata does not exist, the metadata cache will cache an empty optional for the path | Partitioned topic metadata does not exist, the metadata cache will cache an empty optional for the path |
| 4 |  | succeed create the partitioned topic metadata |
| 5 | Receive a ZK node changed event to invalidate the cache of the partitioned topic metadata |
| 6 | Creating the metadata failed due to it already exists |
| 7 | Read the partitioned topic metadata again |

If `step-5` is executed later than `step-7`, `broker-1` will get an empty optional from the cache of the partitioned topic metadata and respond non-partitioned metadata to the client.

**What thing would make the `step-5` is executed later than `step-7`?**
Provide a scenario: Such as the issue that the PR apache#20303 fixed, it makes `zk operation` and `zk node changed notifications`  executed in different threads: `main-thread of ZK client` and `metadata store thread`.

Therefore, the mechanism of the lookup partitioned topic metadata is fragile and we need to optimize it.

Modifications: Before reading the partitioned topic metadata again, refresh the cache first.

… many requests (apache#21216)

Motivation: The Pulsar client will close the socket if it receives a `ServiceNotReady` error when doing a lookup. The Broker will respond to the client with a `TooManyRequests` error if there are too many lookup requests in progress, but the Pulsar Proxy responds to the client with a `ServiceNotReady` error in the same scenario.

Modifications: Make Pulsar Proxy respond to the client with a `TooManyRequests` error if there are too many lookup requests in progress.

…er id when switch ledger (apache#21201)

…ing queue is not empty (apache#21259)

Reproduce steps:
- Create a reader.
- Reader pulls messages into `incoming queue`, do not call `reader.readNext` now.
- Trim ledger task will delete the ledgers, then there is no in the topic.
- Now, you can get messages if you call `reader.readNext`, but the method `reader.hasMessageAvailable` return `false`

Note: the similar issue of `MultiTopicsConsumerImpl` has been fixed by apache#13332, current PR only trying to fix the issue of `ConsumerImpl`.

Make `reader.hasMessageAvailable` return `true` when `incoming queue` is not empty.

(cherry picked from commit 6d82b09)
(cherry picked from commit 38c3f0c)
### Motivation

After trimming ledgers, the variable `lastConfirmedEntry` of the managed ledger might rely on a deleted ledger(the latest ledger which contains data).

There is a bug that makes pulsar allow users to set the start read position to an unexisting ledger or a deleted ledger when creating a subscription. This makes the `backlog` and `markDeletedPosition` wrong.

### Modifications

Fix the bug.

…gers (apache#21250)

### Background
- But after trimming ledgers, `ml.lastConfirmedPosition` relies on a deleted ledger when the current ledger of ML is empty.
- Cursor prevents setting `markDeletedPosition` to a value larger than `ml.lastConfirmedPosition`, but there are no entries to read<sup>[1]</sup>.
- The code description in the method `advanceCursors` said: do not make `cursor.markDeletedPosition` larger than `ml.lastConfirmedPosition`<sup>[2]</sup>

### Issue
If there is no durable cursor, the `markDeletedPosition` might be set to `{current_ledger, -1}`, and `async mark delete` will be prevented by the `rule-2` above. So he `backlog`, `readPosition`, and `markDeletedPosition` of the cursor will be in an incorrect position after trimming the ledger. You can reproduce it by the test `testTrimLedgerIfNoDurableCursor`

### Modifications
Do not make `cursor.markDeletedPosition` larger than `ml.lastConfirmedPosition` when advancing non-durable cursors.

…ne faster (apache#21183)

There is an issue similar to the apache#21155 fixed one.

The client assumed the connection was inactive, but the Broker assumed the connection was fine. The Client tried to  use a new connection to reconnect an exclusive consumer, then got an error `Exclusive consumer is already connected`

- Check the connection of the old consumer is available when the new one tries to subscribe

…ptions caused by wrong topicName (apache#21997)

Similar to: apache#20131

The master branch has fixed the issue by apache#19841 Since it will makes users can not receive the messages which created in mistake, we did not cherry-pick apache#19841 into other branches, see detail apache#19841)

It works like this:
1. createSubscription( `tp1` )
2. is partitioned topic?
  `no`: return subscriptions
  `yes`: createSubscription(`tp1-partition-0`)....createSubscription(`tp1-partition-n`)

---

```java
String partitionedTopic = "tp1-partition-0-DLQ";

TopicName partition0 = partitionedTopic.getPartition(0);// Highlight: the partition0.toString() will be "tp1-partition-0-DLQ"(it is wrong).The correct value is "tp1-partition-0-DLQ-partition-0"
```

Therefore, if there has a partitioned topic named `tp1-partition-0-DLQ`, the method `PersistentTopics.createSubscription` will works like this:
1. call Admin API ``PersistentTopics.createSubscription("tp1-partition-0-DLQ")`
2. is partitioned topic?
3. yes, call `TopicName.getPartition(0)` to get partition 0 and will get `tp1-partition-0-DLQ` , then loop to step-1.

Then the infinite HTTP call `PersistentTopics.createSubscription` makes the broker crash.

If hits the issue which makes the topic name wrong, do not loop to step 1.

The PR apache#19841 fixes the issue which makes the topic name wrong, and this PR will create unfriendly compatibility, and PIP 263 apache#20033 will make compatibility good.
