+# SCYLLA_ASSERT to scylla_assert() Conversion Summary
+
+## Objective
+
+Replace crash-inducing `SCYLLA_ASSERT` with exception-throwing `scylla_assert()` to prevent cluster-wide crashes and maintain availability.
+
+## What Was Done
+
+### 1. Infrastructure Implementation ✓
+
+Created new `scylla_assert()` macro in `utils/assert.hh`:
+- Based on `on_internal_error()` for exception-based error handling
+- Supports optional custom error messages via variadic arguments
+- Uses `seastar::format()` for string formatting
+- Compatible with C++23 standard (uses `__VA_OPT__`)
+
+**Key difference from SCYLLA_ASSERT:**
+```cpp
+// Old: Crashes the process immediately
+SCYLLA_ASSERT(condition);
+
+// New: Throws exception (or aborts based on config)
+scylla_assert(condition);
+scylla_assert(condition, "custom error message: {}", value);
+```
+
+### 2. Comprehensive Analysis ✓
+
+Analyzed entire codebase to identify safe vs unsafe conversion locations:
+
+**Statistics:**
+- Total SCYLLA_ASSERT usages: ~1307 (including tests)
+- Non-test usages: ~886
+- **Unsafe to convert**: 223 usages (25%)
+  - In noexcept functions: 187 usages across 50 files
+  - In destructors: 36 usages across 25 files
+- **Safe to convert**: ~668 usages (75%)
+- **Converted in this PR**: 112 usages (16.8% of safe conversions)
+
+### 3. Documentation ✓
+
+Created comprehensive documentation:
+
+1. **Conversion Guide** (`docs/dev/scylla_assert_conversion.md`)
+   - Explains safe vs unsafe contexts
+   - Provides conversion strategy
+   - Lists all completed conversions
+   - Includes testing guidance
+
+2. **Unsafe Locations Report** (`docs/dev/unsafe_scylla_assert_locations.md`)
+   - Detailed listing of 223 unsafe locations
+   - Organized by file with line numbers
+   - Separated into noexcept and destructor categories
+
+### 4. Sample Conversions ✓
+
+Converted 112 safe SCYLLA_ASSERT usages across 32 files as demonstration:
+
+| File | Conversions | Context |
+|------|------------|---------|
+| db/large_data_handler.{cc,hh} | 5 | Future-returning functions |
+| db/schema_applier.cc | 1 | Coroutine function |
+| db/system_distributed_keyspace.cc | 1 | Regular function |
+| db/commitlog/commitlog_replayer.cc | 1 | Coroutine function |
+| db/view/row_locking.cc | 2 | Regular function |
+| db/size_estimates_virtual_reader.cc | 1 | Lambda in coroutine |
+| db/corrupt_data_handler.cc | 2 | Lambdas in future-returning function |
+| raft/tracker.cc | 2 | Unreachable code (switch defaults) |
+| service/topology_coordinator.cc | 11 | Coroutine functions (topology operations) |
+| service/storage_service.cc | 28 | Critical node lifecycle operations |
+| sstables/* (22 files) | 58 | SSTable operations (read/write/compress/index) |
+
+All conversions were in **safe contexts** (non-noexcept, non-destructor functions). 3 assertions in storage_service.cc remain as SCYLLA_ASSERT (in noexcept functions).
+
+## Why These Cannot Be Converted
+
+### Unsafe Context #1: noexcept Functions (187 usages)
+
+**Problem**: Throwing from noexcept causes `std::terminate()`, same as crash.
+
+**Example** (from `locator/production_snitch_base.hh`):
+```cpp
+virtual bool prefer_local() const noexcept override {
+    SCYLLA_ASSERT(_backreference != nullptr);  // Cannot convert!
+    return _backreference->prefer_local();
+}
+```
+
+**Solution for these**: Keep as SCYLLA_ASSERT or use `on_fatal_internal_error()`.
+
+### Unsafe Context #2: Destructors (36 usages)
+
+**Problem**: Destructors are implicitly noexcept, throwing causes `std::terminate()`.
+
+**Example** (from `utils/file_lock.cc`):
+```cpp
+~file_lock() noexcept {
+    if (_fd.get() != -1) {
+        SCYLLA_ASSERT(_fd.get() != -1);  // Cannot convert!
+        auto r = ::flock(_fd.get(), LOCK_UN);
+        SCYLLA_ASSERT(r == 0);  // Cannot convert!
+    }
+}
+```
+
+**Solution for these**: Keep as SCYLLA_ASSERT.
+
+## Benefits of scylla_assert()
+
+1. **Prevents Cluster-Wide Crashes**
+   - Exception can be caught and handled gracefully
+   - Failed node doesn't bring down entire cluster
+
+2. **Maintains Availability**
+   - Service can continue with degraded functionality
+   - Better than complete crash
+
+3. **Better Error Reporting**
+   - Includes backtrace via `on_internal_error()`
+   - Supports custom error messages
+   - Configurable abort-on-error for testing
+
+4. **Backward Compatible**
+   - SCYLLA_ASSERT still exists for unsafe contexts
+   - Can be gradually adopted
+
+## Testing
+
+- Created manual test in `test/manual/test_scylla_assert.cc`
+- Verifies passing and failing assertions
+- Tests custom error messages
+- Code review passed with improvements made
+
+## Next Steps (Future Work)
+
+1. **Gradual Conversion**
+   - Convert remaining ~653 safe SCYLLA_ASSERT usages incrementally
+   - Prioritize high-impact code paths first
+
+2. **Review noexcept Functions**
+   - Evaluate if some can be made non-noexcept
+   - Consider using `on_fatal_internal_error()` where appropriate
+
+3. **Integration Testing**
+   - Run full test suite with conversions
+   - Monitor for any unexpected behavior
+   - Validate exception propagation
+
+4. **Automated Analysis Tool**
+   - Create tool to identify safe conversion candidates
+   - Generate conversion patches automatically
+   - Track conversion progress

+## Conclusion
+
+This PR establishes the infrastructure and methodology for replacing SCYLLA_ASSERT with scylla_assert() to improve cluster availability. The sample conversions demonstrate the approach, while comprehensive documentation enables future work.
+
+**Key Achievement**: Provided a safe path forward for converting 75% (~668) of SCYLLA_ASSERT usages to exception-based assertions, while clearly documenting the 25% (~223) that must remain as crash-inducing assertions due to language constraints. Converted 112 usages as demonstration (16.8% of safe conversions), prioritizing critical files like storage_service.cc (node lifecycle) and all sstables files (data persistence), with ~556 remaining.

+# SCYLLA_ASSERT to scylla_assert() Conversion Guide
+
+## Overview
+
+This document tracks the conversion of `SCYLLA_ASSERT` to the new `scylla_assert()` macro based on `on_internal_error()`. The new macro throws exceptions instead of crashing the process, preventing cluster-wide crashes and loss of availability.
+
+## Status Summary
+
+- **Total SCYLLA_ASSERT usages**: ~1307 (including tests)
+- **Non-test usages**: ~886
+- **Unsafe conversions (noexcept)**: ~187
+- **Unsafe conversions (destructors)**: ~36
+- **Safe conversions possible**: ~668
+- **Converted so far**: 112
+
+## Safe vs Unsafe Contexts
+
+### Safe to Convert ✓
+- Regular functions (non-noexcept)
+- Coroutine functions (returning `future<T>`)
+- Member functions without noexcept specifier
+- Functions where exception propagation is acceptable
+
+### Unsafe to Convert ✗
+1. **noexcept functions** - throwing exceptions from noexcept causes `std::terminate()`
+2. **Destructors** - destructors are implicitly noexcept
+3. **noexcept lambdas and callbacks**
+4. **Code with explicit exception-safety requirements** that cannot handle exceptions
+
+## Files with Unsafe Conversions
+
+### Files with SCYLLA_ASSERT in noexcept contexts (examples)
+
+1. **reader_concurrency_semaphore.cc**
+   - Lines with noexcept functions containing SCYLLA_ASSERT
+   - Must remain as SCYLLA_ASSERT
+
+2. **db/large_data_handler.cc**
+   - Line 86: `maybe_delete_large_data_entries()` - marked noexcept but contains SCYLLA_ASSERT
+   - Analysis shows this is actually safe (not truly noexcept)
+
+3. **db/row_cache.cc**
+   - Multiple SCYLLA_ASSERT usages in noexcept member functions
+
+4. **db/schema_tables.cc**
+   - SCYLLA_ASSERT in noexcept contexts
+
+5. **raft/server.cc**
+   - Multiple noexcept functions with SCYLLA_ASSERT

+   - Lines 34, 36: SCYLLA_ASSERT in destructor
+
+5. **utils/disk_space_monitor.cc**
+   - Line 66: SCYLLA_ASSERT in destructor
+
+## Conversion Strategy
+
+### Phase 1: Infrastructure (Completed)
+- Created `scylla_assert()` macro in `utils/assert.hh`
+- Uses `on_internal_error()` for exception-based error handling
+- Supports optional message parameters
+
+### Phase 2: Safe Conversions
+Convert SCYLLA_ASSERT to scylla_assert in contexts where:
+- Function is not noexcept
+- Not in a destructor
+- Exception propagation is safe
+
+### Phase 3: Document Remaining Uses
+For contexts that cannot be converted:
+- Add comments explaining why SCYLLA_ASSERT must remain
+- Consider alternative approaches (e.g., using `on_fatal_internal_error()` in noexcept)

+## Future Work
+
+1. **Automated Analysis Tool**
+   - Create tool to identify safe vs unsafe conversion contexts
+   - Generate reports of remaining conversions
+
+2. **Gradual Conversion**
+   - Convert additional safe usages incrementally
+   - Monitor for any unexpected issues
+
+3. **noexcept Review**
+   - Review functions marked noexcept that contain SCYLLA_ASSERT
+   - Consider if they should use `on_fatal_internal_error()` instead
