+# ThreadLocalCache Method Refactor Plan
+
+## Goal
+Encapsulate local cache operations into methods of the `ThreadLocalCache` struct for better code organization and maintainability.
+
+## Changes Required
+
+### 1. Modify ThreadLocalCache struct (lines 70-74)
+Add member methods:
+- `empty()` - returns true if cache has no nodes
+- `remove()` - pops and returns head node
+- `add(Node* node_)` - pushes node to head
+
+### 2. Update call sites
+
+#### Line 228
+Change: `if(_local_cache.head == nullptr)` → `if(_local_cache.empty())`
+
+#### Lines 233-236 (_alloc_impl success path)
+Replace:
+```cpp
+Node *node = _local_cache.head;
+_local_cache.head = node->next;
+_local_cache.count--;
+mem = static_cast<void*>(node);
+```
+With:
+```cpp
+mem = static_cast<void*>(_local_cache.remove());
+```
+
+#### Lines 253-255 (exception handler)
+Replace:
+```cpp
+node->next = _local_cache.head;
+_local_cache.head = node;
+_local_cache.count++;
+```
+With:
+```cpp
+_local_cache.add(node);
+```
+
+#### Lines 145-147 (_transfer_from_global_to_local)
+Replace direct manipulation with `_local_cache.add(node)`
+
+#### Lines 169-171 (_transfer_from_local_to_global)
+Replace direct manipulation with `_local_cache.remove()`
+
+#### Lines 283-285 (free_size)
+Replace direct manipulation with `_local_cache.add(node)`
+
+## Benefits
+- Eliminates code duplication (add pattern used 3 times)
+- Single source of truth for cache operations
+- Self-documenting code
+- Easier to add bounds checking or assertions later

+# mergerfs - AGENTS.md
+
+This file contains build commands, testing procedures, and code style guidelines for agentic coding assistants working in this repository.
+
+```bash
+# Build project
+make
+
+# Build tests
+make tests
+
+# Clean build artifacts
+make clean
+
+# Build with specific options
+make USE_XATTR=0      # Build without xattr support
+make STATIC=1         # Build static binary
+make LTO=1            # Enable link-time optimization
+
+# Build with debugging and sanitizers
+make NDEBUG= SANITIZE=1
+
+# Install
+make install
+```
+
+### Unit Tests (C++)
+
+```bash
+# Build tests
+make tests
+
+# Run all unit tests
+./build/tests <test_name>
+# Example: ./build/tests config_bool
+
+# Run all tests via acutest framework
+./build/tests
+```
+
+### Integration Tests (Python)
+
+```bash
+# Build the main binary first
+make
+
+# Run all integration tests
+./tests/run-tests <path-to-mergerfs-binary>
+# Example: ./tests/run-tests ./build/mergerfs
+
+# Run a single integration test directly
+./tests/TEST_unlink_rename <path-to-mergerfs-binary>
+```
+
+## Code Style Guidelines
+
+### File Organization
+
+- **Source files**: `src/*.cpp`
+- **Header files**: `src/*.hpp`
+- **Tests**: `tests/*.cpp` (unit), `tests/TEST_*` (integration)
+- **Build**: `Makefile` (no build system generators)
+
+### License Headers
+
+Every source file MUST start with the full ISC license header:
+
+```cpp
+/*
+  ISC License
+
+  Copyright (c) YEAR, Antonio SJ Musumeci <trapexit@spawn.link>
+
+  Permission to use, copy, modify, and/or distribute this software for any
+  purpose with or without fee is hereby granted, provided that the above

+  WITH REGARD TO THIS SOFTWARE INCLUDING ALL IMPLIED WARRANTIES OF

+  WHATSOEVER RESULTING FROM LOSS OF USE, DATA OR PROFITS, WHETHER IN AN
+  ACTION OF CONTRACT, NEGLIGENCE OR OTHER TORTIOUS ACTION, ARISING OUT OF
+  OR CONNECTION WITH THE USE OR PERFORMANCE OF THIS SOFTWARE.
+*/
+```
+
+### Include Guards and Ordering
+
+Use `#pragma once` for header guards. Organize includes as:
+
+```cpp
+#include "local_header.hpp"   // Local headers first
+#include <system_header>      // Then system headers
+
+#include <system_headers.h>   // C headers last, if needed
+```
+
+### Naming Conventions
+
+- **Classes**: `PascalCase` (e.g., `Branches`, `Config`, `Policy`)
+- **Functions/methods**: `snake_case` (e.g., `minfreespace()`, `from_string()`)
+- **Variables**: `snake_case` (e.g., `branches_`, `fusepath_`)
+- **Private members**: `_prefix` (e.g., `_impl`, `_mutex`)
+- **Constants/macros**: `SCREAMING_SNAKE_CASE` (e.g., `MINFREESPACE_DEFAULT`)
+- **Namespaces**: `PascalCase` for major namespaces, `lowercase` for utilities (e.g., `Policy`, `fs`, `str`)
+
+### Indentation and Formatting
+
+- **Indentation**: 2 spaces
+- **Brace style**: K&R style
+- **Line length**: No strict limit, but keep readable (~80-100 chars preferred)
+- **No trailing whitespace**
+
+```cpp
+namespace Policy
+{
+  class ActionImpl
+  {
+  public:
+    ActionImpl(const std::string &name_)
+      : name(name_)
+    {
+    }
+
+  public:
+    std::string name;
+    virtual int operator()(...) const = 0;
+  };
+}
+```
+
+### Types and Type Safety
+
+- **Language**: C++17 (`-std=c++17`)
+- **Use standard types**: `int`, `uint64_t`, `size_t`, etc.
+- **Custom typedefs**: Use `typedef` for common configuration types:
+  ```cpp
+  typedef ToFromWrapper<bool> ConfigBOOL;
+  typedef ToFromWrapper<uint64_t> ConfigUINT64;
+  ```
+- **Smart pointers**: Use `std::shared_ptr`, `std::unique_ptr` appropriately
+
+### Error Handling
+
+- **Return values**: Functions return `0` for success, negative `errno` for errors
+- **System call errors**: Return negative errno (e.g., `-EACCES`, `-ENOENT`)
+- **Error propagation**: Keep negative errno values through the call stack
+
+```cpp
+int
+fs::some_function(const fs::path &path_)
+{
+  int rv = ::actual_syscall(path_);
+  if(rv < 0)
+    return -errno;
+  return rv;
+}
+```
+
+Use the `error_and_continue()` macro for policy error handling:
+
+```cpp
+#define error_and_continue(CUR,ERR) \
+  {                                 \
+    policy::calc_error(CUR,ERR);    \
+    continue;                       \
+  }
+```
+
+### Functions and Methods
+
+- **Static helpers**: Prefix with `_` when file-local (e.g., `_helper_function()`)
+- **Namespaces**: Explicitly use namespace qualifiers for organization
+- **Parameters**: Pass by const reference for complex types, by value for simple types
+- **Output parameters**: Use pointers or references
+
+```cpp
+static
+int
+_helper_function(const Branches::Ptr  &branches_,
+                std::vector<Branch*> &paths_)
+{
+  // Implementation
+  return 0;
+}
+
+namespace FUSE
+{
+  int
+  open(const fuse_req_ctx_t *ctx,
+       const char           *fusepath,
+       fuse_file_info_t     *ffi);
+}
+```
+
+### Testing Style
+
+**Unit tests (C++)** use the Acutest framework:
+
+```cpp
+void
+test_config_bool()
+{
+  ConfigBOOL v;
+
+  TEST_CHECK(v.from_string("true") == 0);
+  TEST_CHECK(v == true);
+  TEST_CHECK(v.to_string() == "true");
+
+  TEST_CHECK(v.from_string("false") == 0);
+  TEST_CHECK(v == false);
+  TEST_CHECK(v.to_string() == "false");
+
+  TEST_CHECK(v.from_string("asdf") == -EINVAL);
+}
+
+TEST_LIST =
+  {
+   {"config_bool",test_config_bool},
+   {NULL,NULL}
+  };
+```
+
+**Integration tests (Python)** are scripts prefixed with `TEST_` that test specific filesystem behaviors.
+
+### Compiler Warnings
+
+The Makefile uses strict warnings with `-Werror` for:
+- `-Wpessimizing-move` / `-Werror=pessimizing-move`
+- `-Wredundant-move` / `-Werror=redundant-move`
+- `-Wall`, `-Wextra`, `-Wno-unused-result`, `-Wno-unused-parameter`
+
+Code must compile without warnings.
+
+### Version Notes
+
+- Only tagged releases are officially supported
+- `master` and other branches are works in progress
+- Always ensure code compiles and tests pass before submitting changes

-# ecfd: embeddable C feature discovery
-
-This is a simple script and set of tests to help with what would traditionally be the `configure` step of most C/C++. It is intended to be simple to be embedded into a project and only depends on the C compiler and /bin/sh.
-
-
-## USAGE
-
-First copy `ecfd` into your project. Next simply call the build script which will run the tests and output a `config.` style file to `stdout`. Compile errors will output to `stderr` which can be used to understand why they aren't working.
-
-```
-$ ./ecfd/build > include/config.h
-```
-
-## TESTS
-
-Each test is in a single module. The build script will try to compile each module and on success will execute the program. If anything is printed to `stdout` it will be appended to the `#define` printed to the build script's `stdout`. If the compilation fails nothing will be printed. Look at the tests directory for examples.
