+# These are the list of GN files that run exec_script. This whitelist exists

+#
+# GYPI_TO_GN
+#
+# Some of these entries are for legacy gypi_to_gn calls. We should not be
+# adding new calls to this script in the build (see //build/gypi_to_gn.py for
+# detailed advice). The only time you should be editing this list for
+# gypi_to_gn purposes is when moving an existing call to a different place.
+#
+# 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 existance 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.

+# About src/base:
+#
+# Chromium is a very mature project, most things that are generally useful are
+# already here, and that things not here aren't generally useful.
+#
+# Base is pulled into many projects. For example, various ChromeOS daemons. So
+# the bar for adding stuff 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.

+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` / `syzyasan` `valgrind`, the
+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 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.
+
+
+Appendixes
+----------
+**How does the Windows shim layer replace the malloc symbols?**  
+The mechanism for hooking LIBCMT in Windows is rather tricky.  The core
+problem is that by default, the Windows library does not declare malloc and
+free as weak symbols.  Because of this, they cannot be overridden.  To work
+around this, we start with the LIBCMT.LIB, and manually remove all allocator
+related functions from it using the visual studio library tool.  Once removed,
+we can now link against the library and provide custom versions of the
+allocator related functionality.
+See the script `preb_libc.py` in this folder.
