* [Store] Support degraded startup when master is unavailable
Problem:
P2P client startup fails when master is unavailable, blocking the
entire application. This is problematic for scenarios where the
client should be able to start independently and wait for master
to become available.
Solution:
1. Refactor P2PClientService::Init to support degraded startup:
- Try ConnectToMaster/RegisterClient, allow failure
- Set HA state to FULL or DEGRADED based on connection result
- Skip MountSegment in degraded mode
- Heartbeat thread will recover when master becomes available
2. Optimize initialization order:
- ConnectToMaster/RegisterClient first
- StartHeartbeat before InitTransferEngine (faster heartbeat)
- InitTransferEngine and InitStorage after heartbeat starts
3. Add HARecoveryManager::SetState() for setting initial state
4. Make connection_interrupted_ atomic for thread-safe access
Changes:
- ha_recovery_manager.h: Add SetState() method
- client_service.h/cpp: Support degraded startup in heartbeat logic
- p2p_client_service.cpp: Refactor Init flow with degraded support

* [Store] Refactor HA recovery manager and client service
1. Remove unused master_server_entry parameter from ReconnectToMaster.
In non-HA mode, current_master_address is already initialized to
master_server_entry, making the parameter redundant.
2. Replace SetState() with constructor initial_state parameter.
SetState() bypasses the state machine transition logic, which breaks
encapsulation. Initial state should only be set during construction.
3. Add WaitForReady() to encapsulate initialization wait logic.
Extracts the ready_for_recovery_ and data_manager_ check into a
separate method for better readability in RecoveryPipelineMain.

* [Store] Add HTTP metrics endpoint for Client
Add HTTP server to expose client metrics via Prometheus-compatible endpoints.
This brings Client metrics exposure in line with Master's implementation.
Changes:
- Add metrics_port (default: 9003) and enable_metrics_http config options
- Add coro_http_server in ClientService for metrics HTTP endpoints
- Expose /metrics, /metrics/summary, and /health endpoints
- Add GetMetricsPort() and IsMetricsHttpEnabled() API methods
- Fix port type from int16_t to uint16_t to avoid overflow for ports > 32767
- Add unit tests for config builder and metrics settings
- Fix parameter passing in HA integration test

* [Client] Fix invalid return value in StartMetricsHttpServer
Return 0 instead of -1 on failure, since the function returns uint16_t.
-1 would be implicitly converted to 65535, which is a valid port number
and could cause confusion.
Co-Authored-By: Claude (antchat/GLM-5) <noreply@anthropic.com>
* [Client] Add HA state to health endpoint
Add GetHealthStatus() virtual method to ClientService, returning "OK"
by default. P2PClientService overrides it to return the current HA
state (FULL/DEGRADED/SYNCING) via HARecoveryManager.
Also add toString(HAClientState) helper in types.h for consistent
string conversion.

Cherry-picked from main branch commits:
- 30ca086 [CI] Improve Code Formatting Workflow (#1368)
- 0267e35 [CI] chore: update clang-format to v20.1.8 and enforce version 20 (#1379)
- e9f2887 [Misc] Fix silent failure in `code_format.sh` when clang-format is missing (#1824)
Why partial cherry-pick:
The original commits include changes to .github/workflows/ci.yml that conflict
with P2P-Mooncake-Store branch (which has additional changes like Ninja build
support, branch name modifications, etc.). Instead of resolving complex merge
conflicts, we manually applied the following changes:
Files changed:
1. scripts/code_format.sh (new) - script for incremental format checking
2. .github/workflows/ci.yml - clang-format job updated to use the script
3. .github/pull_request_template.md - added format checklist item
4. .pre-commit-config.yaml - clang-format v19.1.0 -> v20.1.8
Benefits:
- Reduces CI time by only checking changed files instead of all 500+ files
- Supports --check mode for CI and --all mode for local full scan
- Properly handles PR vs push events with correct base ref detection

1. MasterRestartRecovery: Add retry logic for client2 reconnection
- Each client has its own connection pool, so both need to clear stale
connections independently after master restart
- Previously client1 had 10 retries but client2 only tried once
2. ForceRecover: Add re-registration on recovery failure
- If master restarted and lost client registration, recovery would fail
with CLIENT_NOT_FOUND error and get stuck in SYNCING state
- Now retries with re-registration if stuck in SYNCING state

Cherry-picked from main branch commit 79266ffb4d.
Due to significant branch divergence, not all changes were cherry-picked:
- CI workflow files (ci.yml, ci_cu13.yml) were manually adapted
- Dockerfile and ci_ascend.yml were skipped (not present in this branch)
- Add limit_jobs.cmake module for memory-aware build parallelism
- Auto-detect available memory and CPU cores to calculate safe job limits
- With Ninja, create separate job pools for compilation (~1.5GB/job) and linking (~4GB/job)
- Switch CI workflows to use Ninja generator
- Add ninja-build to dependencies.sh
This helps prevent OOM during linking on high-core machines.

* fix: propagate PutViaRoute error in P2PClientService::Put
Put() logged errors from PutViaRoute but always returned success (empty
expected), causing callers to believe the write succeeded when the
underlying route write actually failed with SEGMENT_NOT_FOUND or
NO_AVAILABLE_HANDLE.
Return the error for non-idempotent failures while still treating
REPLICA_NUM_EXCEEDED / REPLICA_ALREADY_EXISTS as success (object already
stored).
Fixes#1817
* fix: also capture remote write errors in PutViaRoute result
Address review feedback from Gemini Code Assist:
1. PutViaRoute: assign write_result error to result before continue
in the remote write path. Previously, if all remote candidates
failed, result stayed default-initialized (success) because only
local write failures were captured.
2. Put: simplify return to use result directly instead of
re-wrapping with tl::unexpected.

* [Store] Fix use-after-free in StorageTier::FlushInternal
Add is_flushing_ flag to StorageBuffer to prevent Free() from
destroying a buffer while FlushInternal() is using it.
Race condition fixed:
1. FlushInternal() snapshots buffers and clears pending_batch_
2. FlushInternal() unlocks and starts IO
3. Free() called - buffer not in pending_batch_, not yet persisted
4. Free() destroys buffer -> FlushInternal() crashes on Persist()
Fix:
- FlushInternal() sets is_flushing_=true before unlock
- Free() calls WaitForFlushComplete() to wait for flush
- FlushInternal() sets is_flushing_=false after Persist()

* [Store] Fix data race in StorageBuffer between Persist and ReadTo
Add data_mutex_ to protect data_ vector access. Without this lock,

- Persist() clears data_ and sets is_on_disk_=true
- ReadTo() accesses cleared data_ -> undefined behavior
The TieredBackend per-key lock doesn't prevent this because
FlushInternal() operates at StorageTier level without acquiring
TieredBackend locks.

with re-check under entry write lock for concurrent race safety
- TieredBackend::Get: remove redundant out_version write

- Add SelectBucketForEviction() and EvictBucket() methods to BucketStorageBackend
- Track valid key count per bucket for fragmentation calculation
- Implement MarkKeyDeleted() to update fragmentation metrics on key deletion
- Add TriggerBucketEviction() to StorageTier for manual eviction

- Loop eviction until target size is met (max 10 attempts)
- Auto-trigger eviction in Allocate() when capacity exceeded
- Update persisted_size_ after eviction to reflect freed space
- Add AutoEvictionOnCapacityExceeded test
This addresses the issue where single bucket eviction may not free
enough space, and enables automatic space reclamation when the
scheduler encounters capacity constraints.

aclrtGetDeviceCount() and aclrtSetDevice() were being called
without first initializing the ACL framework via aclInit().
This fix adds a thread-safe static initialization of ACL in
AscendCacheTier::Init() that:
- Calls aclInit() exactly once across all instances
- Handles ACL_ERROR_REPEAT_INITIALIZE gracefully if ACL is
already initialized by other components
- Returns an error if ACL initialization fails

TieredBackend doesn't have a Read method. Updated the
CopyBetweenAscendTiersSameDevice test to verify allocation tier
type instead of attempting to read data.

- Fix race condition in Allocate() using compare-and-swap (CAS) operation
to atomically check and reserve space before device memory allocation
- Upgrade memory ordering from relaxed to acquire/release for proper
cross-thread visibility of usage counter updates
- Add rollback logic when device memory allocation fails after space
reservation

* client rpc接口定义和data_manager初步实现
* 解决编译问题
* 补充头文件依赖
* 删除多余代码
* client集成改为optional
* add data manager test and adapt to new DataSource
* stub implementation and format change
* clang-formatting
* add lock contention test
* clang-format code style
* implement client rpc service
* Add tests for read lock removal safety verification
Added two test cases to verify that removing read locks from
DataManager::Get and ReadRemoteData is safe:
- ConcurrentGetAndDelete: Tests concurrent Get/Delete operations
- HandleKeepsDataAliveAfterDelete: Verifies handle keeps data alive after deletion
These tests validate that TieredBackend's internal locking and shared_ptr
reference counting provide sufficient thread safety.
