# These are the list of GN files that run exec_script. This whitelist exists
# to force additional review for new uses of exec_script, which is strongly
# discouraged.
#
# PLEASE READ
#
# You should almost never need to add new exec_script calls. exec_script is
# slow, especially on Windows, and can cause confusing effects. Although
# individually each call isn't slow or necessarily very confusing, at the scale
# of our repo things get out of hand quickly. By strongly pushing back on all
# additions, we keep the build fast and clean. If you think you need to add a
# new call, please consider:
#
# - Do not use a script to check for the existence of a file or directory to
# enable a different mode. Instead, use GN build args to enable or disable
# functionality and set options. An example is checking for a file in the
# src-internal repo to see if the corresponding src-internal feature should
# be enabled. There are several things that can go wrong with this:
#
# - It's mysterious what causes some things to happen. Although in many cases
# such behavior can be conveniently automatic, GN optimizes for explicit
# and obvious behavior so people can more easily diagnose problems.
#
# - The user can't enable a mode for one build and not another. With GN build
# args, the user can choose the exact configuration of multiple builds
# using one checkout. But implicitly basing flags on the state of the
# checkout, this functionality is broken.
#
# - It's easy to get stale files. If for example the user edits the gclient
# to stop checking out src-internal (or any other optional thing), it's
# easy to end up with stale files still mysteriously triggering build
# conditions that are no longer appropriate (yes, this happens in real
# life).
#
# - Do not use a script to iterate files in a directory (glob):
#
# - This has the same "stale file" problem as the above discussion. Various
# operations can leave untracked files in the source tree which can cause
# surprising effects.
#
# - It becomes impossible to use "git grep" to find where a certain file is
# referenced. This operation is very common and people really do get
# confused when things aren't listed.
#
# - It's easy to screw up. One common case is a build-time script that packs
# up a directory. The author notices that the script isn't re-run when the
# directory is updated, so adds a glob so all the files are listed as
# inputs. This seems to work great... until a file is deleted. When a
# file is deleted, all the inputs the glob lists will still be up to date
# and no command-lines will have been changed. The action will not be
# re-run and the build will be broken. It is possible to get this correct
# using glob, and it's possible to mess it up without glob, but globs make
# this situation much easier to create. if the build always lists the
# files and passes them to a script, it will always be correct.

# What is this
Contains a written down set of principles and other information on //base.
Please add to it!
## About //base:
Chromium is a very mature project. Most things that are generally useful are
already here and things not here aren't generally useful.
The bar for adding stuff to base is that it must have demonstrated wide
applicability. Prefer to add things closer to where they're used (i.e. "not
base"), and pull into base only when needed. In a project our size,
sometimes even duplication is OK and inevitable.
Adding a new logging macro `DPVELOG_NE` is not more clear than just
writing the stuff you want to log in a regular logging statement, even
if it makes your calling code longer. Just add it to your own code.
If the code in question does not need to be used inside base, but will have
multiple consumers across the codebase, consider placing it in a new directory
under components/ instead.
base is written for the Chromium project and is not intended to be used
outside it. Using base outside of src.git is explicitly not supported,
and base makes no guarantees about API (or even ABI) stability (like all
other code in Chromium). New code that depends on base/ must be in
src.git. Code that's not in src.git but pulled in through DEPS (for
example, v8) cannot use base.
## Qualifications for being in //base OWNERS
* interest and ability to learn low level/high detail/complex c++ stuff
* inclination to always ask why and understand everything (including external
interactions like win32) rather than just hoping the author did it right
* mentorship/experience
* demonstrated good judgement (esp with regards to public APIs) over a length
of time
Owners are added when a contributor has shown the above qualifications and
when they express interest. There isn't an upper bound on the number of OWNERS.
## Design and naming
* Be sure to use the base namespace.
* STL-like constructs should adhere as closely to STL as possible. Functions
and behaviors not present in STL should only be added when they are related
to the specific data structure implemented by the container.
* For STL-like constructs our policy is that they should use STL-like naming
even when it may conflict with the style guide. So functions and class names
should be lower case with underscores. Non-STL-like classes and functions
should use Google naming.
## Performance testing
Since the primitives provided by //base are used very widely, it is important to
ensure they scale to the necessary workloads and perform well under all
supported platforms. The `base_perftests` target is a suite of
synthetic microbenchmarks that measure performance in various scenarios:
* BasicPostTaskPerfTest: Exercises MessageLoopTaskRunner's multi-threaded
queue in isolation.
* ConditionVariablePerfTest: Measures thread switching cost of condition
variables.
* IntegratedPostTaskPerfTest: Exercises the full MessageLoop/RunLoop
machinery.
* JSONPerfTest: Tests JSONWriter and JSONReader performance.
* MessageLoopPerfTest: Measures the speed of task posting in various
configurations.
* ObserverListPerfTest: Exercises adding, removing and signalling observers.
* PthreadEventPerfTest: Establishes the baseline thread switching cost using
pthreads.
* ScheduleWorkTest: Measures the overhead of MessagePump::ScheduleWork.
* SequenceManagerPerfTest: Benchmarks SequenceManager scheduling with various
underlying task runners.
* TaskObserverPerfTest: Measures the incremental cost of adding task
observers.
* TaskPerfTest: Checks the cost of posting tasks between threads.
* WaitableEvent{Thread,}PerfTest: Measures waitable events in single and
multithreaded scenarios.
Regressions in these benchmarks can generally by caused by 1) operating system
changes, 2) compiler version or flag changes or 3) changes in //base code
itself.

This document describes how malloc / new calls are routed in the various Chrome
platforms.
Bare in mind that the chromium codebase does not always just use `malloc()`.
Some examples:
- Large parts of the renderer (Blink) use two home-brewed allocators,
PartitionAlloc and BlinkGC (Oilpan).
- Some subsystems, such as the V8 JavaScript engine, handle memory management
autonomously.
- Various parts of the codebase use abstractions such as `SharedMemory` or
`DiscardableMemory` which, similarly to the above, have their own page-level
memory management.
Background
----------
The `allocator` target defines at compile-time the platform-specific choice of
the allocator and extra-hooks which services calls to malloc/new. The relevant
build-time flags involved are `use_allocator` and `use_allocator_shim`.
The default choices are as follows:
**Windows**
`use_allocator: winheap`, the default Windows heap.
Additionally, `static_library` (i.e. non-component) builds have a shim
layer wrapping malloc/new, which is controlled by `use_allocator_shim`.
The shim layer provides extra security features, such as preventing large
allocations that can hit signed vs. unsigned bugs in third_party code.
**Linux Desktop / CrOS**
`use_allocator: tcmalloc`, a forked copy of tcmalloc which resides in
`third_party/tcmalloc/chromium`. Setting `use_allocator: none` causes the build
to fall back to the system (Glibc) symbols.
**Android**
`use_allocator: none`, always use the allocator symbols coming from Android's
libc (Bionic). As it is developed as part of the OS, it is considered to be
optimized for small devices and more memory-efficient than other choices.
The actual implementation backing malloc symbols in Bionic is up to the board
config and can vary (typically *dlmalloc* or *jemalloc* on most Nexus devices).
**Mac/iOS**
`use_allocator: none`, we always use the system's allocator implementation.
In addition, when building for `asan` / `msan` both the allocator and the shim
layer are disabled.
Layering and build deps
-----------------------
The `allocator` target provides both the source files for tcmalloc (where
applicable) and the linker flags required for the Windows shim layer.
The `base` target is (almost) the only one depending on `allocator`. No other
targets should depend on it, with the exception of the very few executables /
dynamic libraries that don't depend, either directly or indirectly, on `base`
within the scope of a linker unit.
More importantly, **no other place outside of `/base` should depend on the
specific allocator** (e.g., directly include `third_party/tcmalloc`).
If such a functional dependency is required that should be achieved using
abstractions in `base` (see `/base/allocator/allocator_extension.h` and
`/base/memory/`)
**Why `base` depends on `allocator`?**
Because it needs to provide services that depend on the actual allocator
implementation. In the past `base` used to pretend to be allocator-agnostic
and get the dependencies injected by other layers. This ended up being an
inconsistent mess.
See the [allocator cleanup doc][url-allocator-cleanup] for more context.
Linker unit targets (executables and shared libraries) that depend in some way
on `base` (most of the targets in the codebase) get automatically the correct
set of linker flags to pull in tcmalloc or the Windows shim-layer.
Source code
-----------
This directory contains just the allocator (i.e. shim) layer that switches
between the different underlying memory allocation implementations.
The tcmalloc library originates outside of Chromium and exists in
`../../third_party/tcmalloc` (currently, the actual location is defined in the
allocator.gyp file). The third party sources use a vendor-branch SCM pattern to
track Chromium-specific changes independently from upstream changes.
The general intent is to push local changes upstream so that over
time we no longer need any forked files.
Unified allocator shim
----------------------
On most platforms, Chrome overrides the malloc / operator new symbols (and
corresponding free / delete and other variants). This is to enforce security
checks and lately to enable the
[memory-infra heap profiler][url-memory-infra-heap-profiler].
Historically each platform had its special logic for defining the allocator
symbols in different places of the codebase. The unified allocator shim is
a project aimed to unify the symbol definition and allocator routing logic in
a central place.
- Full documentation: [Allocator shim design doc][url-allocator-shim].
- Current state: Available and enabled by default on Android, CrOS, Linux,
Mac OS and Windows.
- Tracking bug: [https://crbug.com/550886][crbug.com/550886].
- Build-time flag: `use_allocator_shim`.
**Overview of the unified allocator shim**
The allocator shim consists of three stages:
```
+-------------------------+ +-----------------------+ +----------------+
| malloc & friends | -> | shim layer | -> | Routing to |
| symbols definition | | implementation | | allocator |
+-------------------------+ +-----------------------+ +----------------+
| - libc symbols (malloc, | | - Security checks | | - tcmalloc |
| calloc, free, ...) | | - Chain of dispatchers| | - glibc |
| - C++ symbols (operator | | that can intercept | | - Android |
| new, delete, ...) | | and override | | bionic |
| - glibc weak symbols | | allocations | | - WinHeap |
| (__libc_malloc, ...) | +-----------------------+ +----------------+
+-------------------------+
```
**1. malloc symbols definition**
This stage takes care of overriding the symbols `malloc`, `free`,
`operator new`, `operator delete` and friends and routing those calls inside the
allocator shim (next point).
This is taken care of by the headers in `allocator_shim_override_*`.
*On Windows*: Windows' UCRT (Universal C Runtime) exports weak symbols, that we
can override in `allocator_shim_override_ucr_symbols_win.h`.
*On Linux/CrOS*: the allocator symbols are defined as exported global symbols
in `allocator_shim_override_libc_symbols.h` (for `malloc`, `free` and friends)
and in `allocator_shim_override_cpp_symbols.h` (for `operator new`,
`operator delete` and friends).
This enables proper interposition of malloc symbols referenced by the main
executable and any third party libraries. Symbol resolution on Linux is a breadth first search that starts from the root link unit, that is the executable
(see EXECUTABLE AND LINKABLE FORMAT (ELF) - Portable Formats Specification).
Additionally, when tcmalloc is the default allocator, some extra glibc symbols
are also defined in `allocator_shim_override_glibc_weak_symbols.h`, for subtle
reasons explained in that file.
The Linux/CrOS shim was introduced by
[crrev.com/1675143004](https://crrev.com/1675143004).
*On Android*: load-time symbol interposition (unlike the Linux/CrOS case) is not
possible. This is because Android processes are `fork()`-ed from the Android
zygote, which pre-loads libc.so and only later native code gets loaded via
`dlopen()` (symbols from `dlopen()`-ed libraries get a different resolution
scope).
In this case, the approach instead of wrapping symbol resolution at link time
(i.e. during the build), via the `--Wl,-wrap,malloc` linker flag.
The use of this wrapping flag causes:
- All references to allocator symbols in the Chrome codebase to be rewritten as
references to `__wrap_malloc` and friends. The `__wrap_malloc` symbols are
defined in the `allocator_shim_override_linker_wrapped_symbols.h` and
route allocator calls inside the shim layer.
- The reference to the original `malloc` symbols (which typically is defined by
the system's libc.so) are accessible via the special `__real_malloc` and
friends symbols (which will be relocated, at load time, against `malloc`).
In summary, this approach is transparent to the dynamic loader, which still sees
undefined symbol references to malloc symbols.
These symbols will be resolved against libc.so as usual.
More details in [crrev.com/1719433002](https://crrev.com/1719433002).
**2. Shim layer implementation**
This stage contains the actual shim implementation. This consists of:
- A singly linked list of dispatchers (structs with function pointers to `malloc`-like functions). Dispatchers can be dynamically inserted at runtime
(using the `InsertAllocatorDispatch` API). They can intercept and override
allocator calls.
- The security checks (suicide on malloc-failure via `std::new_handler`, etc).
This happens inside `allocator_shim.cc`
**3. Final allocator routing**
The final element of the aforementioned dispatcher chain is statically defined
at build time and ultimately routes the allocator calls to the actual allocator
(as described in the *Background* section above). This is taken care of by the
headers in `allocator_shim_default_dispatch_to_*` files.

// - Configure the behavior of the allocator (what to do on OOM failures).
// - Install new hooks (AllocatorDispatch) in the allocator chain.
// When this shim layer is enabled, the route of an allocation is as-follows:
//
// [allocator_shim_override_*.h] Intercept malloc() / operator new calls:
// The override_* headers define the symbols required to intercept calls to
// malloc() and operator new (if not overridden by specific C++ classes).
//
// [allocator_shim.cc] Routing allocation calls to the shim:
// The headers above route the calls to the internal ShimMalloc(), ShimFree(),
// ShimCppNew() etc. methods defined in allocator_shim.cc.
// These methods will: (1) forward the allocation call to the front of the
// AllocatorDispatch chain. (2) perform security hardenings (e.g., might
// call std::new_handler on OOM failure).
//
// [allocator_shim_default_dispatch_to_*.cc] The AllocatorDispatch chain:
// It is a singly linked list where each element is a struct with function
// pointers (|malloc_function|, |free_function|, etc). Normally the chain
// consists of a single AllocatorDispatch element, herein called
// the "default dispatch", which is statically defined at build time and
// ultimately routes the calls to the actual allocator defined by the build
// config (tcmalloc, glibc, ...).
//
// It is possible to dynamically insert further AllocatorDispatch stages
// to the front of the chain, for debugging / profiling purposes.
//
// All the functions must be thread safe. The shim does not enforce any
// serialization. This is to route to thread-aware allocators (e.g, tcmalloc)
// wihout introducing unnecessary perf hits.

# PartitionAlloc Design
This document describes PartitionAlloc at a high level. For documentation about
its implementation, see the comments in `partition_alloc.h`.
[TOC]
## Overview
PartitionAlloc is a memory allocator optimized for security, low allocation
latency (when called appropriately), and good space efficiency (when called
appropriately). This document aims to help you understand how PartitionAlloc
works so that you can use it effectively.
## Partitions And Buckets
A *partition* is a heap that contains certain object types, objects of certain
sizes, or objects of a certain lifetime (as the caller prefers). Callers can
create as many partitions as they need. Each partition is separate and protected
from any other partitions.
Each partition holds multiple buckets. A *bucket* is a region in a partition
that contains similar-sized objects.
PartitionAlloc aligns each object allocation with the closest bucket size. For
example, if a partition has 3 buckets for 64 bytes, 256 bytes, and 1024 bytes,
then PartitionAlloc will satisfy an allocation request for 128 bytes by rounding
it up to 256 bytes and allocating from the second bucket.
## Performance
The current implementation is optimized for the main thread use-case. For
example, PartitionAlloc doesn't have threaded caches.
PartitionAlloc is designed to be extremely fast in its fast paths. The fast
paths of allocation and deallocation require just 2 (reasonably predictable)
branches. The number of operations in the fast paths is minimal, leading to the
possibility of inlining.
For an example of how to use partitions to get good performance and good safety,
see Blink's usage, as described in `wtf/allocator/Allocator.md`.
Large allocations (> kMaxBucketed == 960KB) are realized by direct
memory mmapping. This size makes sense because 960KB = 0xF0000. The next larger
bucket size is 1MB = 0x100000 which is greater than 1/2 the available space in
a SuperPage meaning it would not be possible to pack even 2 sequential
allocations in a SuperPage.
`PartitionRoot<internal::ThreadSafe>::Alloc()` acquires a lock for thread
safety. (The current implementation uses a spin lock on the assumption that
thread contention will be rare in its callers. The original caller was Blink,
where this is generally true. Spin locks also have the benefit of simplicity.)
Callers can get thread-unsafe performance using a
`PartitionRoot<internal::NotThreadSafe>::Alloc()` or otherwise using
`PartitionAlloc<internal::NotThreadSafe>`. Callers can also arrange for low
contention, such as by using a dedicated partition for single-threaded,
latency-critical allocations.
Because PartitionAlloc guarantees that address space regions used for one
partition are never reused for other partitions, partitions can eat a large
amount of virtual address space (even if not of actual memory).
Mixing various random objects in the same partition will generally lead to lower
efficiency. For good performance, group similar objects into the same partition.
## Security
Security is one of the most important goals of PartitionAlloc.
PartitionAlloc guarantees that different partitions exist in different regions
of the process' address space. When the caller has freed all objects contained
in a page in a partition, PartitionAlloc returns the physical memory to the
operating system, but continues to reserve the region of address space.
PartitionAlloc will only reuse an address space region for the same partition.
PartitionAlloc also guarantees that:
* Linear overflows cannot corrupt into the partition. (There is a guard page at
the beginning of each partition.)
* Linear overflows cannot corrupt out of the partition. (There is a guard page
at the end of each partition.)
* Linear overflow or underflow cannot corrupt the allocation metadata.
PartitionAlloc records metadata in a dedicated region out-of-line (not adjacent
to objects).
* Objects of different sizes will likely be allocated in different buckets, and
hence at different addresses. One page can contain only similar-sized objects.
* Dereference of a freelist pointer should fault.
* Partial pointer overwrite of freelist pointer should fault.
* Large allocations have guard pages at the beginning and end.
## Alignment
PartitionAlloc doesn't have explicit support for a `posix_memalign()` type call,
however it provides some guarantees on the alignment of returned pointers.
All pointers are aligned on the smallest allocation granularity, namely
`sizeof(void*)`. Additionally, for power-of-two sized allocations, the behavior
depends on the compilation flags:
* With `DCHECK_IS_ON()`, returned pointers are never guaranteed to be aligned on
more than 16 bytes.
* Otherwise, the returned pointer is guaranteed to be aligned on
`min(allocation_size, system page size)`.
See the tests in `partition_alloc_unittest.cc` for more details.
