Looks like graphviz is no longer a dependency, so this is no longer needed. |

We encountered SIGSEGV when running Python test `python/ray/tests/test_failure_2.py::test_list_named_actors_timeout`.

However, the static variables declared in `logging.cc` are not initialized yet (in this case, `std::string RayLog::logger_name_ = "ray_log_sink"`). It's better not to rely on the initialization order of static variables in different compilation units because it's not guaranteed. I propose to change all `RAY_LOG`s to `std::cerr` in `DelayManager::Init()`. The crash happens in Ant's internal codebase. Not sure why this test case passes in the community version though. BTW, I've tried different approaches: 1. Using a static local variable in `get_delay_us` and remove the global variable. This doesn't work because `init()` needs to access the variable as well. 2. Defining the global variable as type `std::unique_ptr<DelayManager>` and initialize it in `get_delay_us`. This works but it requires a lock to be thread-safe.

…BRT: "corrupted size vs. prev_size") (ray-project#58660) ## Summary This PR fixes a heap corruption bug that causes the driver to crash with SIGABRT. The issue is caused by a use-after-free when the `RayletClient` object is destroyed while an asynchronous RPC callback is still pending. ## Problem Description ### Scenario A Ray Data job (Ray 2.50.0) with pipeline `read_parquet -> filter -> map_batches -> write` running for 4+ hours, where workers use elastic resources with low job priority causing frequent worker deaths due to pod preemption, crashes the driver with SIGABRT: ``` corrupted size vs. prev_size *** SIGABRT received at time=1761916578 on cpu 30 *** PC: @ 0x7f073569d9fc (unknown) pthread_kill Aborted (core dumped) ``` ### Trigger Conditions After reproducing with an ASan image, Asan reveals the actual use-after-free at: ``` #0 0x7ff282967361 in std::__atomic_base<long>::fetch_sub(long, std::memory_order)

src/ray/rpc/retryable_grpc_client.cc:45 ``` This is a **non-deterministic race condition** that occurs under the following sequence: 1. Worker A's pod is preempted → Worker A dies 2. Objects on Worker A are lost 3. Objects are found on Worker B → `PinObjectIDs` RPC is initiated 4. Worker B dies or becomes unavailable → `CheckChannelStatus` detects this → `Disconnect` is called 5. The `RayletClient` corresponding to Worker B on the driver is destroyed 6. RPC callback executes and accesses the already-freed `RayletClient` → use-after-free triggers crash Whether the use-after-free occurs depends on the relative timing of steps 5 and 6. In scenarios with frequent pod preemptions, object recovery frequently triggers `PinObjectIDs`, making this race condition more likely to occur. ### Root Cause In `RayletClient::PinObjectIDs`, the RPC callback lambda directly captured the raw `this` pointer: ```cpp auto rpc_callback = [this, callback = std::move(callback)](...) { pins_in_flight_--; // Accessing member via 'this' pointer ... }; ``` If the `RayletClient` object is destroyed before the async RPC callback executes, the callback will access freed memory through the dangling `this` pointer, leading to heap corruption and SIGABRT with the error message "corrupted size vs. prev_size". ## Solution The fix ensures that the `RayletClient` object remains alive during the asynchronous callback execution by: 1. **Inheriting from `std::enable_shared_from_this<RayletClient>`**: The class already inherits from this base class (line 43 in `raylet_client.h`), which enables safe shared pointer management. 2. **Capturing `shared_from_this()` in the lambda**: Instead of capturing the raw `this` pointer, the callback now captures a `shared_ptr` to the object. The `shared_from_this()` is called before incrementing `pins_in_flight_` to ensure proper lifetime management: ```cpp // Capture shared_from_this() before incrementing to ensure object lifetime // is extended for the async callback, preventing use-after-free. auto self = shared_from_this(); pins_in_flight_++; auto rpc_callback = [self, callback = std::move(callback)]( Status status, rpc::PinObjectIDsReply &&reply) { self->pins_in_flight_--; callback(status, std::move(reply)); }; ``` This ensures that the `RayletClient` object's lifetime is extended until the callback completes, preventing the use-after-free bug. By capturing the shared pointer before incrementing the counter, we also ensure that if `shared_from_this()` were to fail (though it shouldn't in normal usage), we don't leave the counter in an inconsistent state. ## Code Changes - **File**: `src/ray/raylet_rpc_client/raylet_client.cc` - **Method**: `RayletClient::PinObjectIDs` - **Change**: Replace `this` capture with `shared_from_this()` capture in the RPC callback lambda Signed-off-by: dragongu <andrewgu@vip.qq.com> Co-authored-by: gulonglong <gulonglong@stepfun.com>

…BRT: "corrupted size vs. prev_size") (ray-project#58660) ## Summary This PR fixes a heap corruption bug that causes the driver to crash with SIGABRT. The issue is caused by a use-after-free when the `RayletClient` object is destroyed while an asynchronous RPC callback is still pending. ## Problem Description ### Scenario A Ray Data job (Ray 2.50.0) with pipeline `read_parquet -> filter -> map_batches -> write` running for 4+ hours, where workers use elastic resources with low job priority causing frequent worker deaths due to pod preemption, crashes the driver with SIGABRT: ``` corrupted size vs. prev_size *** SIGABRT received at time=1761916578 on cpu 30 *** PC: @ 0x7f073569d9fc (unknown) pthread_kill Aborted (core dumped) ``` ### Trigger Conditions After reproducing with an ASan image, Asan reveals the actual use-after-free at: ``` #0 0x7ff282967361 in std::__atomic_base<long>::fetch_sub(long, std::memory_order)

src/ray/rpc/retryable_grpc_client.cc:45 ``` This is a **non-deterministic race condition** that occurs under the following sequence: 1. Worker A's pod is preempted → Worker A dies 2. Objects on Worker A are lost 3. Objects are found on Worker B → `PinObjectIDs` RPC is initiated 4. Worker B dies or becomes unavailable → `CheckChannelStatus` detects this → `Disconnect` is called 5. The `RayletClient` corresponding to Worker B on the driver is destroyed 6. RPC callback executes and accesses the already-freed `RayletClient` → use-after-free triggers crash Whether the use-after-free occurs depends on the relative timing of steps 5 and 6. In scenarios with frequent pod preemptions, object recovery frequently triggers `PinObjectIDs`, making this race condition more likely to occur. ### Root Cause In `RayletClient::PinObjectIDs`, the RPC callback lambda directly captured the raw `this` pointer: ```cpp auto rpc_callback = [this, callback = std::move(callback)](...) { pins_in_flight_--; // Accessing member via 'this' pointer ... }; ``` If the `RayletClient` object is destroyed before the async RPC callback executes, the callback will access freed memory through the dangling `this` pointer, leading to heap corruption and SIGABRT with the error message "corrupted size vs. prev_size". ## Solution The fix ensures that the `RayletClient` object remains alive during the asynchronous callback execution by: 1. **Inheriting from `std::enable_shared_from_this<RayletClient>`**: The class already inherits from this base class (line 43 in `raylet_client.h`), which enables safe shared pointer management. 2. **Capturing `shared_from_this()` in the lambda**: Instead of capturing the raw `this` pointer, the callback now captures a `shared_ptr` to the object. The `shared_from_this()` is called before incrementing `pins_in_flight_` to ensure proper lifetime management: ```cpp // Capture shared_from_this() before incrementing to ensure object lifetime // is extended for the async callback, preventing use-after-free. auto self = shared_from_this(); pins_in_flight_++; auto rpc_callback = [self, callback = std::move(callback)]( Status status, rpc::PinObjectIDsReply &&reply) { self->pins_in_flight_--; callback(status, std::move(reply)); }; ``` This ensures that the `RayletClient` object's lifetime is extended until the callback completes, preventing the use-after-free bug. By capturing the shared pointer before incrementing the counter, we also ensure that if `shared_from_this()` were to fail (though it shouldn't in normal usage), we don't leave the counter in an inconsistent state. ## Code Changes - **File**: `src/ray/raylet_rpc_client/raylet_client.cc` - **Method**: `RayletClient::PinObjectIDs` - **Change**: Replace `this` capture with `shared_from_this()` capture in the RPC callback lambda Signed-off-by: dragongu <andrewgu@vip.qq.com> Co-authored-by: gulonglong <gulonglong@stepfun.com>
