Your primary goal is to eliminate │ │ unsafe buffer operations by migrating legacy C-style code to modern, │ │ safer C++ constructs, with a strong emphasis on `base::span` and │ │ other standard library containers. You must adhere to Chromium's │ │ coding standards and the specific guidelines for this task. │ │ │ │ **Task:** Your task is to fix unsafe buffer usage in a given C++ │ │ file. You should compile the target with provided command line after │ │ removing the `#pragma allow_unsafe_buffers` and `UNSAFE_TODO` │ │ directive. You will use these errors to identify and fix the unsafe │ │ code, applying the principles and patterns outlined below. **Your │ │ changes must be minimal and targeted, directly addressing only the │ │ unsafe buffer errors.** While the primary focus is on the given │ │ file, you are expected to modify other files (e.g., header files or │ │ call sites) if necessary to ensure the code compiles and tests pass. │ │ │ │ ### **Guiding Philosophy** │ │ * **Safety Through the Type System:** The fundamental goal is to │ │ encode buffer size information into the C++ type system. A `char*` │ │ has no size information, making it unsafe. A `base::span` has │ │ a size, making it safe. Every change you make should serve this │ │ principle. │ │ * **Minimalism is Essential:** Your task is not to refactor or │ │ improve the code in general. You are a specialist surgeon fixing one │ │ specific problem: unsafe buffer usage. Make the smallest possible │ │ change that fixes the compiler warning and passes tests. │ │ * **Trust, But Verify with Compilation:** Your primary feedback │ │ loop is the compiler. After removing the `allow_unsafe_buffers` │ │ pragma, the `-Wunsafe-buffer-usage` errors are your map. Use them to │ │ identify every location that needs a fix. │ │ │ │ │ │ You must refer to these documents to ensure your solutions are │ │ idiomatic and correct within the Chromium ecosystem. │ │ │ │ # Workflow Tips │ │ │ │ ## General Workflow: │ │ │ │ * **User Guidance:** Proactively communicate your plan and the │ │ reason for each │ │ step. │ │ * **File Creation Pre-check:** Before creating any new file, you │ │ MUST first │ │ perform a thorough search for existing files that can be │ │ modified or │ │ extended. This is especially critical for tests; never create a │ │ new test │ │ file if one already exists for the component in question. Always │ │ add new │ │ tests to the existing test file. │ │ * **Read Before Write/Edit:** **ALWAYS** read the entire file │ │ content │ │ immediately before writing or editing. │ │ │ │ ## MANDATORY DEBUGGING PROTOCOL (WHEN STUCK) │ │ │ │ * **Trigger:** You **MUST** activate this protocol if you │ │ encounter a │ │ **Repeated Tool or Command Failure**. │ │ │ │ * **Definition of Repeated Failure:** A tool or command (e.g., │ │ `autoninja`, `autotest.py`, `git cl format`, `replace`) │ │ fails. You apply │ │ a fix or change your approach. You run the *exact same tool │ │ or command* │ │ again, and it fails for a **second time**. │ │ * **Sensitivity:** This protocol is intentionally highly │ │ sensitive. The │ │ error message for the second failure does **NOT** need to be │ │ the same as │ │ the first. Any subsequent failure of the same tool or │ │ command after a │ │ fix attempt is a trigger. This is to prevent "whack-a-mole" │ │ scenarios │ │ where fixing one error simply reveals another, indicating a │ │ deeper │ │ underlying problem. │ │ │ │ *Check your history to confirm the repeated failure of the tool │ │ or command.* │ │ │ │ * **Action:** If the trigger condition is met: │ │ │ │ 1. **STOP:** **DO NOT** immediately retry the *same* fix or │ │ re-run the │ │ *same* tool or command again. │ │ 2. **INFORM USER:** Immediately inform the user that you are │ │ invoking the │ │ debugging protocol because a tool or command has failed │ │ twice in a row. │ │ 3. **REASON:** **Explicitly state** which tool or command │ │ failed repeatedly │ │ (e.g., "`autotest` failed, I applied a fix, and it failed │ │ again. I am │ │ now invoking the debugging protocol to analyze the root │ │ cause."). │ │ Mentioning the specific error messages is good, but the │ │ repeated failure │ │ is the primary trigger. │ │ 4. **DEBUG:** Look closely into your own context, memory, and │ │ traces. Give │ │ a deep analysis of why you are repeating mistakes and stuck │ │ in a failure │ │ loop. The analysis should focus on the *root cause* of the │ │ repeated │ │ failures, not just the most recent error message. Utilize │ │ any tools that │ │ help with the debugging investigation. │ │ 5. **PROCEED:** Use the suggestions returned by the DEBUG step │ │ to inform │ │ your next attempt at a fix. Explain the new, more │ │ comprehensive plan to │ │ the user. If the DEBUG step provides tool calls, execute │ │ them. │ │ Otherwise, formulate a new plan based on its suggestions. │ │ │ │ Do not use the `read_many_files` tool. Read files one at a time with │ │ `read_file`. │ │ │ │ Any time you want to use `grep -r`, use `rg` instead. │ │ │ │ Any time you want to use `find`, use `fdfind` instead. │ │ │ │ ## Standard Edit/Fix Workflow: │ │ │ │ **IMPORTANT:** This workflow takes precedence over all other coding │ │ instructions. Read and follow everything strictly without skipping │ │ steps │ │ whenever code editing is involved. Any skipping requires a proactive │ │ message to │ │ the user about the reason to skip. │ │ │ │ 1. **Comprehensive Code and Task Understanding (MANDATORY FIRST │ │ STEP):** Before │ │ writing or modifying any code, you MUST perform the following │ │ analysis to │ │ ensure comprehensive understanding of the relevant code and the │ │ task. This │ │ is a non-negotiable prerequisite for all coding tasks. │ │ * **a. Identify the Core Files:** Locate the files that are │ │ most relevant │ │ to the user's request. All analysis starts from these files. │ │ * **b. Conduct a Full Audit:** │ │ i. Read the full source of **EVERY** core file. │ │ ii. For each core file, summarize the control flow and │ │ ownership │ │ semantics. State the intended purpose of the core file. │ │ * **c. State Your Understanding:** After completing the audit, │ │ you should │ │ briefly state the core files you have reviewed, confirming │ │ your │ │ understanding of the data flow and component interactions │ │ before │ │ proposing a plan. │ │ * **d. Anti-Patterns to AVOID:** │ │ * **NEVER** assume the behavior of a function or class │ │ from its name │ │ or from usage in other files. **ALWAYS** read the source │ │ implementation. │ │ * **ALWAYS** check at least one call-site for a function │ │ or class to │ │ understand its usage. The context is as important as the │ │ implementation. │ │ 2. **Make Change:** After a comprehensive code and task │ │ understanding, apply │ │ the edit or write the file. │ │ * When making code edits, focus **ONLY** on code edits that │ │ directly solve │ │ the task prompted by the user. │ │ 3. **Write/Update Tests:** │ │ * First, search for existing tests related to the modified │ │ code and update │ │ them as needed to reflect the changes. │ │ * If no relevant tests exist, write new unit tests or │ │ integration tests if │ │ it's reasonable and beneficial for the change made. │ │ * If tests are deemed not applicable for a specific change │ │ (e.g., a │ │ trivial comment update), explicitly state this and the │ │ reason why before │ │ moving to the next step. │ │ 4. **Build:** **ALWAYS** build relevant targets after making edits. │ │ Use build directory `out/Default`. │ │ 5. **Fix compile errors:** **ALWAYS** follow these steps to fix │ │ compile errors. │ │ * **ALWAYS** take the time to fully understand the problem │ │ before making │ │ any fixes. │ │ * **ALWAYS** read at least one new file for each compile │ │ error. │ │ * **ALWAYS** find, read, and understand **ALL** files related │ │ to each │ │ compile error. For example, if an error is related to a │ │ missing member │ │ of a class, find the file that defines the interface for the │ │ class, read │ │ the whole file, and then create a high-level summary of the │ │ file that │ │ outlines all core concepts. Come up with a plan to fix the │ │ error. │ │ * **ALWAYS** check the conversation history to see if this │ │ same │ │ error occurred earlier, and analyze previous solutions to │ │ see why they │ │ didn't work. │ │ * **NEVER** make speculative fixes. You should be confident │ │ before │ │ applying any fix that it will work. If you are not │ │ confident, read more │ │ files. │ │ 6. **Test:** **ALWAYS** run relevant tests after a successful │ │ build. If you │ │ cannot find any relevant test files, you may prompt the user to │ │ ask how this │ │ change should be tested. │ │ 7. **Fix test errors**: │ │ * **ALWAYS** take the time to fully understand the problem │ │ before making │ │ any fixes. │ │ 8. **Iterate:** Repeat building and testing using the above steps │ │ until all are │ │ successful. │ │ │ │ --- │ │ │ │ ### **Core Principles for Safe Buffer Handling** │ │ │ │ Before looking at specific patterns, adhere to these fundamental │ │ principles. │ │ │ │ * **Principle 0: Clearly Distinguish Ownership** │ │ Before you change any code, your first step is to determine if │ │ the variable in question represents owning or non-owning memory. │ │ This single decision dictates the correct C++ type to use. │ │ │ │ * **Owning Buffers:** Use an owning container when the code is │ │ responsible for the memory's lifetime (allocating and freeing it). │ │ * `std::vector`: This is the default and preferred │ │ choice for a dynamically-sized, owning buffer. │ │ * `std::string`: The standard choice for owning a buffer │ │ of characters. │ │ * `std::array`: Use this for a fixed-size buffer │ │ whose lifetime is tied to its scope (typically on the stack). It's a │ │ direct, safer replacement for C-style arrays like `int │ │ my_array[10];`. │ │ * `base::HeapArray`: A Chromium-specific alternative │ │ for heap-allocated arrays, sometimes useful for interfacing with │ │ legacy code. │ │ │ │ * **Non-Owning Buffers (Views/Spans):** Use a non-owning view │ │ when the code needs to safely refer to and operate on memory that is │ │ owned by another object (like a `std::vector` or `std::array`). │ │ * `base::span`: This is the default and preferred │ │ choice for a non-owning, mutable, or immutable view of a contiguous │ │ sequence of objects. It's the primary tool for replacing `(T* ptr, │ │ size_t size)` parameters. │ │ * `std::string_view`: Use this for a non-owning, read-only │ │ view of a sequence of characters. It provides a rich set of │ │ string-manipulation methods (`.starts_with()`, `.find()`, etc.) that │ │ `base::span` lacks. │ │ │ │ * **Principle 1: Avoid Unsafe APIs, Even If They Look Modern.** │ │ The goal is to eliminate the *root cause* of unsafety, not just │ │ silence the compiler. Certain modern-looking APIs are still unsafe. │ │ │ │ * **DO NOT USE:** The `base::span(pointer, size)` constructor. │ │ It is marked `UNSAFE_BUFFER_USAGE` for a reason—it does not verify │ │ that `size` is a valid length for `pointer`. Using it is no safer │ │ than the original code. │ │ * **DO NOT USE:** `std::next()` or `std::advance()` to silence │ │ buffer warnings. These functions perform unchecked pointer │ │ arithmetic and are just as unsafe as `ptr + offset`. │ │ ```cpp │ │ // Old and Unsafe (silences warning, but still dangerous): │ │ auto it = std::find(std::next(vec.begin(), offset), │ │ vec.end(), 20); │ │ // New and Safe: │ │ auto it = std::ranges::find(base::span(vec).subspan(offset), │ │ 20); │ │ ``` │ │ * **DO NOT USE:** `base::StringView`. This is a legacy, │ │ deprecated type. The correct and modern type for a non-owning string │ │ view is `std::string_view`. Be mindful to use the `std` namespace │ │ for string views. │ │ * **DO NOT USE: `UNSAFE_BUFFERS` without a safety │ │ justification.** Individual expressions can be opted out with │ │ `UNSAFE_BUFFERS()`, but these are for rare cases like interfacing │ │ with C-style external APIs. They **must always** be accompanied by a │ │ `// SAFETY:` comment explaining in detail why the code has been │ │ evaluated to be safe for all possible inputs. Code without this │ │ justification should be rejected. │ │ │ │ * **Principle 3: Prefer Safe, Size-Aware Constructors and │ │ Factories.** Always create spans from sources that already know │ │ their own size. This is the key to memory safety. │ │ │ │ * **DO USE:** `base::span(container)` where `container` is an │ │ `std::vector`, `std::array`, `std::string`, `base::HeapArray`, etc. │ │ * **DO USE:** `base::span(other_span).subspan(...)` to create │ │ safe views into existing spans. │ │ * **DO USE:** `base::as_byte_span(container)` and │ │ `base::as_writable_byte_span(container)` for safe type-punning to a │ │ byte view. │ │ * **DO USE:** `base::span_from_ref(object)` to create a span │ │ of size 1 pointing to a single object. │ │ * **DO USE:** `base::byte_span_from_ref(object)` for a byte │ │ view of a single object. │ │ │ │ --- │ │ │ │ ### **Toolbox of Fixes and Patterns** │ │ │ │ Here is a comprehensive set of patterns for fixing common unsafe │ │ buffer issues. │ │ │ │ #### **1. Fundamental Replacements: Pointers and C-Arrays** │ │ │ │ The most common task is replacing raw pointers and C-style arrays │ │ with safer, bounds-checked alternatives. │ │ │ │ * **Pattern:** Replace function parameters `(T* ptr, size_t size)` │ │ with a single `base::span`. │ │ │ │ * **Example:** │ │ ```cpp │ │ // Old │ │ void ProcessData(const uint8_t* data, size_t size); │ │ │ │ // New │ │ void ProcessData(base::span data); │ │ ``` │ │ │ │ * **Pattern:** Replace C-style stack arrays `T arr[N]` with │ │ `std::array`. For string literals, `std::to_array` is a │ │ convenient helper. │ │ │ │ * **Example:** │ │ ```cpp │ │ // Old │ │ const char kAllowed[] = "abc"; │ │ int values[10]; │ │ │ │ // New │ │ // For C-style string literals, std::to_array is simplest. │ │ constexpr auto kAllowed = std::to_array("abc"); │ │ std::array values; │ │ ``` │ │ │ │ * **Pattern:** Replace raw heap-allocated arrays (`new T[size]`, │ │ `std::make_unique(size)`) with `std::vector` or │ │ `base::HeapArray`. │ │ │ │ * **Reasoning:** `std::vector` and `base::HeapArray` are │ │ self-managing, provide size information, and prevent common memory │ │ management errors. They also integrate perfectly with `base::span`. │ │ * **Example:** │ │ ```cpp │ │ // Old │ │ auto buffer = std::make_unique(1024); │ │ ReadData(fd, buffer.get(), 1024); │ │ │ │ // New │ │ std::vector buffer(1024); │ │ ReadData(fd, base::as_writable_byte_span(buffer)); │ │ ``` │ │ │ │ * **Pattern:** When passing an array to a function, use │ │ `base::span` to create a non-owning view. │ │ │ │ * **Example:** │ │ ```cpp │ │ std::array my_array; │ │ // Old: ProcessData(my_array.data(), my_array.size()); │ │ // New │ │ ProcessData(base::span(my_array)); │ │ ``` │ │ * **Pattern:** For class member fields that are non-owning views, │ │ you must use `base::raw_span` over `base::span`. │ │ * **Reasoning:** This is a critical memory safety requirement. │ │ `base::raw_span` is implemented with MiraclePtr, which protects │ │ against Use-After-Free (UAF) bugs. If the underlying object is │ │ freed, any attempt to use the `raw_span` will result in a controlled │ │ crash instead of allowing dangerous memory corruption or type │ │ confusion attacks. A regular `base::span` offers no UAF protection. │ │ ```cpp │ │ class MyClass { │ │ private: │ │ // Old: base::span data_; │ │ // New: │ │ base::raw_span data_; │ │ }; │ │ ``` │ │ │ │ #### **2. Replacing Unsafe C-Style Library Functions** │ │ │ │ * **Pattern:** Replace `memcpy` and `memmove` with │ │ `base::span::copy_from()`. │ │ * **Reasoning:** Do not use `std::ranges::copy`. It is unsafe │ │ because it does not verify that the source and destination spans │ │ have the same size, which can lead to buffer overflows. │ │ `base::span::copy_from()` is the only safe alternative, as it │ │ includes a `CHECK` to ensure the sizes match exactly. │ │ * **Example:** │ │ ```cpp │ │ // Old │ │ memcpy(dest_ptr, src_ptr, N); │ │ │ │ // New (Safe and Idiomatic) │ │ // This CHECKs that both subspans are of size N. │ │ dest_span.first(N).copy_from(src_span.first(N)); │ │ ``` │ │ │ │ * **Pattern:** Replace `memset` with `std::ranges::fill()`. │ │ │ │ * **Example:** │ │ ```cpp │ │ // Old │ │ memset(buffer, 0, sizeof(buffer)); │ │ │ │ // New │ │ std::ranges::fill(my_span, 0); │ │ ``` │ │ │ │ * **Pattern:** Replace `memcmp` with `base::span::operator==` or │ │ `std::ranges::equal`. │ │ │ │ * **Example:** │ │ ```cpp │ │ // Old │ │ bool are_equal = memcmp(ptr1, ptr2, size) == 0; │ │ │ │ // New │ │ bool are_equal = span1 == span2; │ │ ``` │ │ │ │ #### **3. Eliminating Pointer Arithmetic and Unsafe Casting** │ │ │ │ * **Pattern:** Replace pointer arithmetic like `ptr + offset` with │ │ `span.subspan(offset)`. │ │ │ │ * **Example:** │ │ ```cpp │ │ // Old │ │ ProcessData(data + 10, size - 10); │ │ │ │ // New │ │ ProcessData(data_span.subspan(10)); │ │ ``` │ │ │ │ * **Pattern:** Avoid `reinterpret_cast` for changing element │ │ types. Use safe casting functions like `base::as_bytes()`, │ │ `base::as_writable_byte_span()`, or `base::as_chars()`. │ │ │ │ * **Example:** │ │ ```cpp │ │ // Old │ │ const uint8_t* bytes = reinterpret_cast(str.data()); │ │ │ │ // New │ │ base::span bytes = base::as_byte_span(str); │ │ ``` │ │ * **Caution:** When using `base::as_byte_span()` on a │ │ `struct`, be aware of padding bytes. If the struct's padding is not │ │ explicitly initialized (e.g., via `memset` or aggregate │ │ initialization), reading from the resulting byte span can lead to │ │ reads of uninitialized memory. This is safest with spans of │ │ primitive types. │ │ │ │ * **Pattern:** To read or write structured data (like a │ │ `uint32_t`) from/to a byte buffer, use the endian-converting helpers │ │ from `base/numerics/byte_conversions.h`. │ │ │ │ * **Example (Writing):** │ │ ```cpp │ │ // Old (UNSAFE AND UNDEFINED BEHAVIOR) │ │ *reinterpret_cast(byte_span.data()) = my_value; │ │ │ │ // New (Safe and Idiomatic) │ │ #include "base/numerics/byte_conversions.h" │ │ auto value_bytes = base::U32ToLittleEndian(my_value); │ │ byte_span.first(value_bytes.size()).copy_from(value_bytes); │ │ ``` │ │ │ │ * **Example (Reading):** │ │ ```cpp │ │ // Old (UNSAFE) │ │ uint32_t value = *reinterpret_cast(byte_span.data()); │ │ │ │ // New (Safe and Idiomatic) │ │ #include "base/numerics/byte_conversions.h" │ │ uint32_t value = │ │ base::U32FromLittleEndian(byte_span.first<4>()); │ │ ``` │ │ * **Pattern:** For dynamic or heterogeneous I/O, use │ │ `base::SpanReader` and `base::SpanWriter` to safely consume or │ │ populate a buffer. This is safer and more expressive than manual │ │ pointer casting and offsetting. │ │ * **Example (Writing with `SpanWriter`):** │ │ ```cpp │ │ #include "base/containers/span_writer.h" │ │ #include "base/numerics/byte_conversions.h" │ │ void WriteData(base::span out, uint32_t id, float │ │ value) { │ │ auto writer = base::SpanWriter(out); │ │ writer.WriteU32BigEndian(id); │ │ writer.Write(base::FloatToLittleEndian(value)); │ │ } │ │ ``` │ │ * **Pattern:** Refactor sequential buffer filling with a │ │ "consuming span". This is for cases where a buffer is allocated │ │ once, and then a pointer is manually advanced as data is written to │ │ it sequentially. │ │ * **Reasoning:** Instead of managing a write-pointer and an │ │ end-pointer manually, a single `base::span` can represent the │ │ remaining, writable portion of the buffer. This is safer and more │ │ expressive. │ │ * **Example:** │ │ ```cpp │ │ // Helper function that writes a string and "consumes" part │ │ of the span. │ │ void WriteStringAndAdvance(base::span& buffer, const │ │ char* str) { │ │ if (!str) { │ │ return; │ │ } │ │ const size_t len_with_null = strlen(str) + 1; │ │ DCHECK_GE(buffer.size(), len_with_null); │ │ memcpy(buffer.data(), str, len_with_null); │ │ // The span is sliced, now pointing to the remaining │ │ writable area. │ │ buffer = buffer.subspan(len_with_null); │ │ } │ │ │ │ // Old function that manually manages pointers. │ │ void CreateMessageUnsafe(char* buffer, size_t size, const │ │ char* str1, const char* str2) { │ │ char* ptr = buffer; │ │ const char* end = buffer + size; │ │ │ │ // Manual copy and advance │ │ size_t len1 = strlen(str1) + 1; │ │ CHECK_LE(ptr + len1, end); │ │ memcpy(ptr, str1, len1); │ │ ptr += len1; │ │ │ │ // Another manual copy and advance │ │ size_t len2 = strlen(str2) + 1; │ │ CHECK_LE(ptr + len2, end); │ │ memcpy(ptr, str2, len2); │ │ ptr += len2; │ │ } │ │ │ │ // New function using the "consuming span" pattern. │ │ void CreateMessageSafe(base::span buffer, const char* │ │ str1, const char* str2) { │ │ WriteStringAndAdvance(buffer, str1); │ │ WriteStringAndAdvance(buffer, str2); │ │ // At this point, `buffer` correctly represents the │ │ unused portion. │ │ } │ │ ``` │ │ * **Key Idea:** The core of this pattern is to create a helper │ │ function (like `WriteStringAndAdvance`) that takes the main buffer │ │ span by reference (`&`). The helper writes its data and then │ │ reassigns the span to a smaller subspan, effectively advancing the │ │ "write position" for the next operation in the calling function. │ │ │ │ #### **4. String and Character Manipulation** │ │ │ │ * **Pattern:** Replace C-style string literals (`const char │ │ kFoo[]`) with `constexpr std::string_view kFoo` or `constexpr │ │ std::array`. │ │ * **Pattern:** For C APIs that require a NUL-terminated string, │ │ use `base::cstring_view`. │ │ * **Pattern:** Replace C-style string functions (`strcmp`, │ │ `strstr`, etc.) with `std::string_view` methods (`operator==`, │ │ `.find()`, etc.). │ │ * **Pattern:** Replace pointer-based iteration over a buffer with │ │ a range-based for loop over a `base::span`. │ │ * **Pattern:** Choose the correct string view type based on │ │ null-termination requirements. │ │ * **Reasoning:** You must differentiate between internal C++ │ │ logic and calls to C-style APIs. A `std::string_view` is not │ │ guaranteed to be null-terminated, while `base::cstring_view` │ │ provides this guarantee. Using the wrong type can lead to buffer │ │ over-reads. │ │ * **Decision Flow:** │ │ * If the string is only used with modern C++ methods (like │ │ `.find()` or range `for` loops) that use an explicit size, use │ │ `std::string_view`. │ │ * If the string needs to be passed to an API that requires │ │ a null-terminated `const char*` (like `printf`, `sscanf`, or legacy │ │ functions), you must use `base::cstring_view`. │ │ * **Example:** │ │ ```cpp │ │ // A legacy C-style function │ │ void LogToOldSystem(const char* message); │ │ │ │ // --- │ │ // In some calling code --- │ │ std::string my_string = "Hello, World!"; │ │ std::string_view full_view = my_string; │ │ │ │ // UNSAFE: This substring is not null-terminated in │ │ my_string. │ │ std::string_view unsafe_view = full_view.substr(7, 5); // │ │ "World" │ │ // LogToOldSystem(unsafe_view.data()); // BUG! Reads past │ │ "d" into garbage. │ │ │ │ // SAFE: Create a new std::string which is guaranteed to be │ │ null-terminated. │ │ std::string safe_string(unsafe_view); │ │ LogToOldSystem(safe_string.c_str()); │ │ │ │ // IDEAL: Use a type that enforces the contract. │ │ // If the source is already a C-string, cstring_view is │ │ zero-copy. │ │ base::cstring_view safe_c_view = "Hello, World!"; │ │ LogToOldSystem(safe_c_view.c_str()); │ │ ``` │ │ │ │ │ │ #### **5. Advanced Patterns** │ │ * **Pattern:** To get a heap-allocated buffer with a specific │ │ memory alignment, use `base::AlignedUninit` from │ │ `base/memory/aligned_memory.h`. │ │ ```cpp │ │ #include "base/memory/aligned_memory.h" │ │ // Get an uninitialized array of 16 floats, aligned to 32 bytes. │ │ base::AlignedHeapArray array = │ │ base::AlignedUninit(16, 32); │ │ ``` │ │ │ │ #### **6. Common Chromium-Specific Patterns** │ │ │ │ * **`net::IOBuffer`:** This class and its subclasses │ │ (`IOBufferWithSize`, `VectorIOBuffer`) now have span-like methods. │ │ Use them. │ │ │ │ * **Example:** │ │ ```cpp │ │ // Old │ │ auto data_view = base::span( │ │ reinterpret_cast(io_buffer->data()), │ │ data_len); │ │ │ │ // New │ │ auto data_view = io_buffer->first(data_len); │ │ ``` │ │ │ │ * **`net::VectorIOBuffer`:** To create a buffer with known │ │ content, prefer constructing a `net::VectorIOBuffer` directly from a │ │ `std::vector` or `base::span` instead of allocating a raw buffer │ │ and using `memcpy`. │ │ │ │ * **Example:** │ │ ```cpp │ │ // Old │ │ auto buffer = │ │ base::MakeRefCounted(data.size()); │ │ memcpy(buffer->data(), data.data(), data.size()); │ │ │ │ // New │ │ auto buffer = │ │ base::MakeRefCounted(data); │ │ ``` │ │ │ │ #### **7. Interfacing with C-style/Third-Party APIs** │ │ │ │ * **Pattern:** When a C API returns pointers to different memory │ │ planes (e.g., video frames), create `base::span`s from those │ │ pointers and their known sizes at the API boundary. Use │ │ `UNSAFE_BUFFERS()` for this initial creation, then pass the safe │ │ spans throughout the rest of your C++ code. │ │ * **Example:** │ │ ```cpp │ │ // Old │ │ uint8_t* y_ptr = vpx_image->planes[0]; │ │ uint8_t* u_ptr = vpx_image->planes[1]; │ │ VideoFrame::WrapExternalYuvData(..., y_ptr, u_ptr, ...); │ │ │ │ // New │ │ // SAFETY: libvpx guarantees these pointers and sizes are │ │ valid. │ │ auto y_plane = │ │ UNSAFE_BUFFERS(base::span(vpx_image->planes[0], y_size)); │ │ auto u_plane = │ │ UNSAFE_BUFFERS(base::span(vpx_image->planes[1], u_size)); │ │ VideoFrame::WrapExternalYuvData(..., y_plane, u_plane, ...); │ │ ``` │ │ │ │ #### **8. The Containment Strategy: When a Full Fix is Too Complex** │ │ │ │ Sometimes, a complete refactor is not immediately feasible. In these │ │ cases, contain the unsafe operations. │ │ │ │ * **Strategy:** Instead of a file-level `#pragma`, wrap the │ │ *minimal* number of unsafe operations in the `UNSAFE_TODO()` macro. │ │ This macro acts like `UNSAFE_BUFFERS()` but signals that the code is │ │ a candidate for a future fix. │ │ * **Function-level Annotation:** If a function contains │ │ `UNSAFE_TODO()`, you must also mark the function's signature with │ │ the `UNSAFE_BUFFER_USAGE` attribute. This propagates the unsafety │ │ requirement to its callers, ensuring they are also marked or within │ │ an unsafe block. │ │ * **Example:** │ │ ```cpp │ │ // Old: │ │ // #pragma allow_unsafe_buffers │ │ // void DoSomething(const char* p) { │ │ // p++; │ │ // } │ │ │ │ // New (Contained): │ │ UNSAFE_BUFFER_USAGE void DoSomething(const char* p) { │ │ UNSAFE_TODO(p++); │ │ } │ │ ``` │ │ │ │ #### **9. Handling Redundant Parameters** │ │ │ │ * **Identify redundant parameters:** In functions that now take a │ │ base::span, find any size parameters that are now unneeded. A │ │ parameter is still considered redundant even if it's already used in │ │ a CHECK or DCHECK. │ │ │ │ * **Rename the parameter:** For any redundant parameter, rename it │ │ and all its references within the function by adding the prefix │ │ spanification_suspected_redundant_. │ │ │ │ * **Add a TODO and a CHECK:** At the top of the function body, add │ │ the following two lines: │ │ │ │ * A TODO comment: │ │ ```cpp │ │ // TODO(crbug.com/431824301): Remove unneeded parameter once │ │ validated to be redundant in M143. │ │ ``` │ │ * A CHECK to verify the redundant parameter matches the span's │ │ size: │ │ ```cpp │ │ CHECK(spanification_suspected_redundant_size_variable == │ │ span.size(), base::NotFatalUntil::M143); │ │ ``` │ │ │ │ * **Customize the CHECK:** In the CHECK you just added, you must: │ │ │ │ * Replace spanification_suspected_redundant_size_variable with │ │ the new name of the parameter you renamed in step 2. │ │ │ │ * Replace span.size() with a call to the actual base::span │ │ parameter's .size() method. │ │ │ │ * **Important constraints:** │ │ │ │ * Do not remove the parameter or update any call sites. │ │ │ │ * Do not change the function's logic to use span.size(); │ │ continue to use the newly-renamed parameter variable. │ │ │ │ * Do ensure the size parameter and the base::span's size are │ │ in the same unit before making changes. │ │ │ │ * Do not remove the parameter or the CHECK even if you │ │ confirmed that the unit tests pass. │ │ │ │ #### **10. Updating Function Definitions and Call Sites** │ │ │ │ * **Updating the Function Definition** │ │ * **Identify the target function:** Look for functions that │ │ have a parameter with the name pattern │ │ spanification_suspected_redundant_.... │ │ * **Remove the parameter:** In the function's definition and │ │ any corresponding declarations (e.g., in a header file), completely │ │ remove the redundant size parameter from the parameter list. │ │ * **Replace internal usages:** Inside the function's body, │ │ replace every use of the removed parameter with a call to the │ │ base::span's .size() method (e.g., my_span.size()). │ │ │ │ * **Updating the Call Sites** │ │ * **Find all call sites:** Use a command like git grep with │ │ the function name to find every location where the function is │ │ called throughout the codebase. │ │ * **Remove the argument at each call site:** For each call │ │ site you find, you must remove the argument that corresponds to the │ │ size parameter you deleted from the function's definition. │ │ * **Important:** Be very careful to only remove the specific, │ │ redundant argument. Do not change or remove any other arguments in │ │ the function call. │ │ │ │ * **Key Constraints** │ │ * You should only remove the parameter previously marked as │ │ redundant and its corresponding arguments at call sites. │ │ * Do not remove or rename any other parameters. │ │ * Do not rewrite the function's logic beyond replacing the │ │ deleted variable with span.size(). │ │ * Ensure that when you update a call site, you only remove the │ │ single, correct argument. │ │ │ │ #### **11. Handling Autogenerated Files** │ │ │ │ * **Pattern:** Another common pattern is for a change to require │ │ modification to an autogenerated file. Treat autogenerated files as │ │ unmodifiable for now. │ │ --- │ │ #### **12. Wrapping Unsafe APIs with Macros** │ │ │ │ In some cases, you will encounter functions from third-party │ │ libraries or other unmodifiable parts of the codebase that return a │ │ raw pointer to a buffer. Directly wrapping these with │ │ `UNSAFE_BUFFERS(base::span(pointer, size))` is one option, but a │ │ more robust and reusable solution is to create a dedicated wrapper │ │ macro in `base/containers/auto_spanification_helper.h`. │ │ │ │ * **Strategy:** When an unmodifiable function call returns a raw │ │ pointer instead of a safe container like `base::span`, follow this │ │ procedure: │ │ 1. **Check for an existing macro:** First, examine │ │ `base/containers/auto_spanification_helper.h` to see if a macro for │ │ this specific API call already exists. │ │ 2. **Create a new macro if needed:** If no macro exists, you │ │ must add one. │ │ * The macro should be added to │ │ `base/containers/auto_spanification_helper.h`. │ │ * The macro should take the same arguments as the original │ │ API call. │ │ * Inside the macro, call the original API, get the pointer │ │ and size, and return a `base::span`. Use `UNSAFE_TODO` to wrap the │ │ returned span. │ │ * Follow the existing macro patterns in the file, using a │ │ lambda to avoid multiple argument evaluation. │ │ 3. **Add a test for the new macro:** You must add a new test │ │ case to `base/containers/auto_spanification_helper_unittest.cc`. │ │ * The test should mock the third-party API and verify that │ │ the macro correctly creates a `base::span` with the expected data │ │ and size. │ │ 4. **Use the macro:** Replace the original unsafe API call in │ │ your target file with the new or existing macro. │ │ │ │ * **Example: Adding a macro for `SkBitmap::getAddr32`** │ │ │ │ * **Macro in `auto_spanification_helper.h`:** │ │ ```cpp │ │ // https://source.chromium.org/chromium/chromium/src/+/main: │ │ third_party/skia/include/core/SkBitmap.h;drc=f72bd467feb15edd9323e46 │ │ eab1b74ab6025bc5b;l=936 │ │ #define UNSAFE_SKBITMAP_GETADDR32(arg_self, arg_x, arg_y) \ │ │ ([](auto&& self, int x, int y) { \ │ │ uint32_t* row = self->getAddr32(x, y); \ │ │ ::base::CheckedNumeric width = self->width(); \ │ │ size_t size = (width - x).ValueOrDie(); \ │ │ return UNSAFE_TODO(base::span(row, size)); \ │ │ }(::base::spanification_internal::ToPointer(arg_self), │ │ arg_x, arg_y)) │ │ ``` │ │ │ │ * **Test in `auto_spanification_helper_unittest.cc`:** │ │ ```cpp │ │ // Minimized mock of SkBitmap class defined in │ │ // //third_party/skia/include/core/SkBitmap.h │ │ class SkBitmap { │ │ public: │ │ uint32_t* getAddr32(int x, int y) const { return &row_[x]; │ │ } │ │ int width() const { return static_cast(row_.size()); │ │ } │ │ │ │ mutable std::array row_{}; │ │ }; │ │ │ │ TEST(AutoSpanificationHelperTest, SkBitmapGetAddr32Pointer) │ │ { │ │ SkBitmap sk_bitmap; │ │ const int x = 123; │ │ base::span span = │ │ UNSAFE_SKBITMAP_GETADDR32(&sk_bitmap, x, 0); │ │ EXPECT_EQ(span.data(), &sk_bitmap.row_[x]); │ │ EXPECT_EQ(span.size(), sk_bitmap.row_.size() - x); │ │ } │ │ ``` │ │ --- │ │ │ │ Pattern: Refactor sequential buffer filling with a "consuming span". │ │ This is for cases where a buffer is allocated once, and then a │ │ pointer is manually advanced as data is written to it sequentially. │ │ │ │ Reasoning: Instead of managing a write-pointer and an end-pointer │ │ manually, a single base::span can represent the remaining, writable │ │ portion of the buffer. This is safer and more expressive. │ │ │ │ Example: │ │ │ │ C++ │ │ │ │ --- │ │ // Helper function that writes a string and "consumes" part of the │ │ span. │ │ void WriteStringAndAdvance(base::span& buffer, const char* │ │ str) { │ │ if (!str) { │ │ return; │ │ } │ │ const size_t len_with_null = strlen(str) + 1; │ │ DCHECK_GE(buffer.size(), len_with_null); │ │ memcpy(buffer.data(), str, len_with_null); │ │ // The span is sliced, now pointing to the remaining writable │ │ area. │ │ buffer = buffer.subspan(len_with_null); │ │ } │ │ │ │ // Old function that manually manages pointers. │ │ void CreateMessageUnsafe(char* buffer, size_t size, const char* │ │ str1, const char* str2) { │ │ char* ptr = buffer; │ │ const char* end = buffer + size; │ │ │ │ // Manual copy and advance │ │ size_t len1 = strlen(str1) + 1; │ │ CHECK_LE(ptr + len1, end); │ │ memcpy(ptr, str1, len1); │ │ ptr += len1; │ │ │ │ // Another manual copy and advance │ │ size_t len2 = strlen(str2) + 1; │ │ CHECK_LE(ptr + len2, end); │ │ memcpy(ptr, str2, len2); │ │ ptr += len2; │ │ } │ │ │ │ // New function using the "consuming span" pattern. │ │ void CreateMessageSafe(base::span buffer, const char* str1, │ │ const char* str2) { │ │ WriteStringAndAdvance(buffer, str1); │ │ WriteStringAndAdvance(buffer, str2); │ │ // At this point, `buffer` correctly represents the unused │ │ portion. │ │ } │ │ Key Idea: The core of this pattern is to create a helper function │ │ (like WriteStringAndAdvance) that takes the main buffer span by │ │ reference (&). The helper writes its data and then reassigns the │ │ span to a smaller subspan, effectively advancing the "write │ │ position" for the next operation in the calling function. │ │ --- │ ╰──────────────────────────────────────────────────────────────────────────╯ ✦ Okay, I will start by examining the current patch to understand the changes that have already been made. ╭──────────────────────────────────────────────────────╮ │ ✔ Shell git show HEAD (Examine the current patch.) │ │ │ │ ... first 458 lines hidden ... │ │ @@ -78,15 +79,15 @@ class FileIOTest : │ │ public cdm::FileIOClient { │ │ // |data|, which should be valid │ │ throughout the lifetime of |this| │ │ object. │ │ void AddTestStep(StepType type, │ │ Status status, │ │ - const uint8_t* │ │ data, │ │ + base::spandata, │ │ uint32_t │ │ data_size); │ │ // Adds a test step in this test │ │ that expects a successful read of │ │ either │ │ // |data| or |data2|. |this| object │ │ doesn't take the ownership of |data| or │ │ // |data2|, which should be valid │ │ throughout the lifetime of |this| │ │ object. │ │ void AddResultReadEither(Status │ │ status, │ │ - const │ │ uint8_t* data, │ │ + │ │ base::spandata, │ │ uint32_t │ │ data_size, │ │ - const │ │ uint8_t* data2, │ │ + │ │ base::spandata2, │ │ uint32_t │ │ data2_size); │ │ │ │ // Runs this test case and returns │ │ the test result through │ │ |completion_cb|. │ │ @@ -98,9 +99,9 @@ class FileIOTest : │ │ public cdm::FileIOClient { │ │ // should be valid throughout the │ │ lifetime of |this| object. │ │ TestStep(StepType type, │ │ Status status, │ │ - const uint8_t* data = │ │ nullptr, │ │ + base::spandata = {}, │ │ uint32_t data_size = 0, │ │ - const uint8_t* data2 = │ │ nullptr, │ │ + base::spandata2 = {}, │ │ uint32_t data2_size = 0) │ │ : type(type), │ │ status(status), │ │ @@ -115,11 +116,11 @@ class FileIOTest │ │ : public cdm::FileIOClient { │ │ Status status; │ │ │ │ // Data to write in ACTION_WRITE, │ │ or read data in RESULT_READ. │ │ - const uint8_t* data; │ │ + base::spandata; │ │ uint32_t data_size; │ │ │ │ // Alternate read data in │ │ RESULT_READ, if |data2| != nullptr. │ │ - const uint8_t* data2; │ │ + base::spandata2; │ │ uint32_t data2_size; │ │ }; │ │ │ │ @@ -132,7 +133,7 @@ class FileIOTest : │ │ public cdm::FileIOClient { │ │ // cdm::FileIOClient implementation. │ │ void OnOpenComplete(Status status) │ │ override; │ │ void OnReadComplete(Status status, │ │ - const uint8_t* │ │ data, │ │ + base::spandata, │ │ uint32_t │ │ data_size) override; │ │ void OnWriteComplete(Status status) │ │ override; │ │ │ │ │ ╰──────────────────────────────────────────────────────╯ ✦ I've reviewed the patch and see the initial spanification work. There are remaining unsafe usages, redundant size parameters, and incorrect API calls that need to be addressed. My plan is to: 1. Correct the std::vector creation in cdm_file_adapter.cc to safely use the base::span. 2. Refactor cdm_file_io_test.cc to use safe span comparisons and fix incorrect base::HexEncode arguments. 3. Investigate and update the cdm::FileIO::Write method to accept a base::span, which will involve finding its definition and updating all call sites. 4. Remove redundant data_size parameters from all modified functions and structures, updating call sites accordingly.
