ce8c9a63109214519b5a7eaecef2c663c4d566df by Greg Falcon <gfalcon@google.com>:
Implement the config options for our four main C++ forward compatibility types.
These options control whether the names `any`, `optional`, `string_view`, and `variant` in namespace `absl` are aliases to the corresponding C++17 types in namespace `std`. By default, we continue to auto-detect the configuration of the compiler being run.
These options are not intended to be modified on the command line (as -D flags, say). Instead, the options.h file can be modified by distributors of Abseil (e.g., binary packagers, maintainers of local copies of Abseil, etc.)
Changing options will change Abseil in an ODR sense. Any program must only link in a single version of Abseil. Linking libraries that use Abseil configured with different options is an error: there is no ABI compatibility guarantee when linking different configurations, even if the Abseil versions used are otherwise exactly identical.

Allow building Abseil as a shared library with CMake.
By default CMake's `add_library` creates the target as a static
library. However, users can override the default using the builtin
CMake option -DBUILD_SHARED_LIBS=ON.
This changes Abseil's CMake to respect this configuration option
by removing the explicit `STATIC` in our usages of `add_library`.

Use explicit static_cast<double> for int64_t to double conversion
This uses an explicit static_cast<double>() in the int64_t to double comparisons in duration.cc's SafeAddRepHi. This satisfies clang's -Wimplicit-int-to-float-conversion warning (with https://reviews.llvm.org/D64666). This may also make it easier for humans to realize that the comparison is happening between two floating point double precision values. It should have no impact on the behavior or generated code.

Try to become idle only when there is no wakeup.
Immediately after waking up (when futex wait returns), the current thread tries
to become idle doing bunch of memory loads and a branch. Problem is that there
is a good chance that we woke up due to a wakeup, especially for actively used
threads. For such wakeups, calling MaybeBecomeIdle() would be a waste of
cycles.
Instead, call MaybeBecomeIdle() only when we are sure there is no wakeup. For
idle threads the net effect should be the same. For active, threads this will
be more efficient.
Moreover, since MaybeBecomeIdle() is called before waiting on the futex, the
current thread will try to become idle before sleeping. This should result
in more accurate idleness and more efficient release of thread resources.

|

|
//
|
|
|
|
// A `string_view` provides a lightweight view into the string data provided by
|
|
|
|
// a `std::string`, double-quoted string literal, character array, or even
|
|
|
|
// another `string_view`. A `string_view` does *not* own the string to which it
|
|
|
|
// points, and that data cannot be modified through the view.
|
|
|
|
//
|
|
|
|
// You can use `string_view` as a function or method parameter anywhere a
|
|
|
|
// parameter can receive a double-quoted string literal, `const char*`,
|
|
|
|
// `std::string`, or another `absl::string_view` argument with no need to copy
|
|
|
|
// the string data. Systematic use of `string_view` within function arguments
|
|
|
|
// reduces data copies and `strlen()` calls.
|
|
|
|
//
|
|
|
|
// Because of its small size, prefer passing `string_view` by value:
|
|
|
|
//
|
|
|
|
// void MyFunction(absl::string_view arg);
|
|
|
|
//
|
|
|
|
// If circumstances require, you may also pass one by const reference:
|
|
|
|
//
|
|
|
|
// void MyFunction(const absl::string_view& arg); // not preferred
|
|
|
|
//
|
|
|
|
// Passing by value generates slightly smaller code for many architectures.
|
|
|
|
//
|
|
|
|
// In either case, the source data of the `string_view` must outlive the
|
|
|
|
// `string_view` itself.
|
|
|
|
//
|
|
|
|
// A `string_view` is also suitable for local variables if you know that the
|
|
|
|
// lifetime of the underlying object is longer than the lifetime of your
|
|
|
|
// `string_view` variable. However, beware of binding a `string_view` to a
|
|
|
|
// temporary value:
|
|
|
|
//
|
|
|
|
// // BAD use of string_view: lifetime problem
|
|
|
|
// absl::string_view sv = obj.ReturnAString();
|
|
|
|
//
|
|
|
|
// // GOOD use of string_view: str outlives sv
|
|
|
|
// std::string str = obj.ReturnAString();
|
|
|
|
// absl::string_view sv = str;
|
|
|
|
//
|
|
|
|
// Due to lifetime issues, a `string_view` is sometimes a poor choice for a
|
|
|
|
// return value and usually a poor choice for a data member. If you do use a
|
|
|
|
// `string_view` this way, it is your responsibility to ensure that the object
|
|
|
|
// pointed to by the `string_view` outlives the `string_view`.
|
|
|
|
//
|
|
|
|
// A `string_view` may represent a whole string or just part of a string. For
|
|
|
|
// example, when splitting a string, `std::vector<absl::string_view>` is a
|
|
|
|
// natural data type for the output.
|
|
|
|
//
|
|
|
|
// When constructed from a source which is NUL-terminated, the `string_view`
|
|
|
|
// itself will not include the NUL-terminator unless a specific size (including
|
|
|
|
// the NUL) is passed to the constructor. As a result, common idioms that work
|
|
|
|
// on NUL-terminated strings do not work on `string_view` objects. If you write
|
|
|
|
// code that scans a `string_view`, you must check its length rather than test
|
|
|
|
// for nul, for example. Note, however, that nuls may still be embedded within
|
|
|
|
// a `string_view` explicitly.
|
|
|
|
//
|
|
|
|
// You may create a null `string_view` in two ways:
|
|
|
|
//
|
|
|
|
// absl::string_view sv;
|
|
|
|
// absl::string_view sv(nullptr, 0);
|
|
|
|
//
|
|
|
|
// For the above, `sv.data() == nullptr`, `sv.length() == 0`, and
|
|
|
|
// `sv.empty() == true`. Also, if you create a `string_view` with a non-null
|
|
|
|
// pointer then `sv.data() != nullptr`. Thus, you can use `string_view()` to
|
|
|
|
// signal an undefined value that is different from other `string_view` values
|
|
|
|
// in a similar fashion to how `const char* p1 = nullptr;` is different from
|
|
|
|
// `const char* p2 = "";`. However, in practice, it is not recommended to rely
|
|
|
|
// on this behavior.
|
|
|
|
//
|
|
|
|
// Be careful not to confuse a null `string_view` with an empty one. A null
|
|
|
|
// `string_view` is an empty `string_view`, but some empty `string_view`s are
|
|
|
|
// not null. Prefer checking for emptiness over checking for null.
|
|
|
|
//
|
|
|
|
// There are many ways to create an empty string_view:
|
|
|
|
//
|
|
|
|
// const char* nullcp = nullptr;
|
|
|
|
// // string_view.size() will return 0 in all cases.
|
|
|
|
// absl::string_view();
|
|
|
|
// absl::string_view(nullcp, 0);
|
|
|
|
// absl::string_view("");
|
|
|
|
// absl::string_view("", 0);
|
|
|
|
// absl::string_view("abcdef", 0);
|
|
|
|
// absl::string_view("abcdef" + 6, 0);
|
|
|
|
//
|
|
|
|
// All empty `string_view` objects whether null or not, are equal:
|
|
|
|
//
|
|
|
|
// absl::string_view() == absl::string_view("", 0)

Avoid the compiler reloading __is_long() on string_view(const string&)
The underlying cause is that the compiler assume a scenario where string_view is created with placement new into memory occupied by the input, so the store to 'ptr' can affect the value / result of size(); i.e., __is_long() reloads the __size value).
Example code: string_view1 demonstrates the problem, string_view2 DTRT.
=== string_view1
struct string_view1 {
string_view1(const char* ptr, size_t n) : ptr(ptr), n(n) {}
string_view1(const std::string& s) : ptr(s.data()), n(s.length()) {}
const char* ptr;
size_t n;

f562f56577b84a8bc07e5873775c01d068531bca by Jon Cohen <cohenjon@google.com>:
Generate Abseil compile options. The single source of truth is now absl/copts/copts.py
The way this works goes something like this:
copts.py acts as the configuration file. We use python because unlike JSON it allows comments. It has two maps in it: one from names to external flags, and one from names to internal flags.
generate_copts.py imports the maps and loops through them to write GENERATED_copts.bzl and GENERATED_AbseilCopts.cmake
AbseilConfigureCopts.cmake and configure_copts.bzl import their respective copts args and set the platform-appropriate copts into ABSL_DEFAULT_COPTS, ABSL_TEST_COPTS, ABSL_EXCEPTIONS_FLAG, and ABSL_EXCEPTIONS_LINKOPTS
For Bazel, each BUILD file load()s configure_copts.bzl
For CMake, AbseilHelpers.cmake include()s AbseilConfigureCopts.cmake to get the final copts and both inserts them as needed into legacy target rules and also makes them available to the rest of our CMakeLists.txt file. We may instead want to include() AbseilConfigureCopts.cmake directly into each CMakeLists.txt file for consistency, but I'm not sure what the deal is with cmake and include guards, or if they are even needed. That's also not as idiomatic -- CMake tends to use directory scope where globals set at a higher level CMakeLists.txt file are used in the subdirectory CMakeLists.txt files.

Try to become idle only when there is no wakeup.
Immediately after waking up (when futex wait returns), the current thread tries
to become idle doing bunch of memory loads and a branch. Problem is that there
is a good chance that we woke up due to a wakeup, especially for actively used
threads. For such wakeups, calling MaybeBecomeIdle() would be a waste of
cycles.
Instead, call MaybeBecomeIdle() only when we are sure there is no wakeup. For
idle threads the net effect should be the same. For active, threads this will
be more efficient.
Moreover, since MaybeBecomeIdle() is called before waiting on the futex, the
current thread will try to become idle before sleeping. This should result
in more accurate idleness and more efficient release of thread resources.

Try to become idle only when there is no wakeup.
Immediately after waking up (when futex wait returns), the current thread tries
to become idle doing bunch of memory loads and a branch. Problem is that there
is a good chance that we woke up due to a wakeup, especially for actively used
threads. For such wakeups, calling MaybeBecomeIdle() would be a waste of
cycles.
Instead, call MaybeBecomeIdle() only when we are sure there is no wakeup. For
idle threads the net effect should be the same. For active, threads this will
be more efficient.
Moreover, since MaybeBecomeIdle() is called before waiting on the futex, the
current thread will try to become idle before sleeping. This should result
in more accurate idleness and more efficient release of thread resources.

Try to become idle only when there is no wakeup.
Immediately after waking up (when futex wait returns), the current thread tries
to become idle doing bunch of memory loads and a branch. Problem is that there
is a good chance that we woke up due to a wakeup, especially for actively used
threads. For such wakeups, calling MaybeBecomeIdle() would be a waste of
cycles.
Instead, call MaybeBecomeIdle() only when we are sure there is no wakeup. For
idle threads the net effect should be the same. For active, threads this will
be more efficient.
Moreover, since MaybeBecomeIdle() is called before waiting on the futex, the
current thread will try to become idle before sleeping. This should result
in more accurate idleness and more efficient release of thread resources.

Try to become idle only when there is no wakeup.
Immediately after waking up (when futex wait returns), the current thread tries
to become idle doing bunch of memory loads and a branch. Problem is that there
is a good chance that we woke up due to a wakeup, especially for actively used
threads. For such wakeups, calling MaybeBecomeIdle() would be a waste of
cycles.
Instead, call MaybeBecomeIdle() only when we are sure there is no wakeup. For
idle threads the net effect should be the same. For active, threads this will
be more efficient.
Moreover, since MaybeBecomeIdle() is called before waiting on the futex, the
current thread will try to become idle before sleeping. This should result
in more accurate idleness and more efficient release of thread resources.

Try to become idle only when there is no wakeup.
Immediately after waking up (when futex wait returns), the current thread tries
to become idle doing bunch of memory loads and a branch. Problem is that there
is a good chance that we woke up due to a wakeup, especially for actively used
threads. For such wakeups, calling MaybeBecomeIdle() would be a waste of
cycles.
Instead, call MaybeBecomeIdle() only when we are sure there is no wakeup. For
idle threads the net effect should be the same. For active, threads this will
be more efficient.
Moreover, since MaybeBecomeIdle() is called before waiting on the futex, the
current thread will try to become idle before sleeping. This should result
in more accurate idleness and more efficient release of thread resources.

Implement the config options for our four main C++ forward compatibility types.
These options control whether the names `any`, `optional`, `string_view`, and `variant` in namespace `absl` are aliases to the corresponding C++17 types in namespace `std`. By default, we continue to auto-detect the configuration of the compiler being run.
These options are not intended to be modified on the command line (as -D flags, say). Instead, the options.h file can be modified by distributors of Abseil (e.g., binary packagers, maintainers of local copies of Abseil, etc.)
Changing options will change Abseil in an ODR sense. Any program must only link in a single version of Abseil. Linking libraries that use Abseil configured with different options is an error: there is no ABI compatibility guarantee when linking different configurations, even if the Abseil versions used are otherwise exactly identical.

Use explicit static_cast<double> for int64_t to double conversion
This uses an explicit static_cast<double>() in the int64_t to double comparisons in duration.cc's SafeAddRepHi. This satisfies clang's -Wimplicit-int-to-float-conversion warning (with https://reviews.llvm.org/D64666). This may also make it easier for humans to realize that the comparison is happening between two floating point double precision values. It should have no impact on the behavior or generated code.

Inside Abseil headers, wrap most invocations of methods and functions named `min` and `max` in parentheses, for better interoperability with Windows toolchains.
CCTZ fixes will appear in a follow-up CL.

Generate Abseil compile options. The single source of truth is now absl/copts/copts.py
The way this works goes something like this:
copts.py acts as the configuration file. We use python because unlike JSON it allows comments. It has two maps in it: one from names to external flags, and one from names to internal flags.
generate_copts.py imports the maps and loops through them to write GENERATED_copts.bzl and GENERATED_AbseilCopts.cmake
AbseilConfigureCopts.cmake and configure_copts.bzl import their respective copts args and set the platform-appropriate copts into ABSL_DEFAULT_COPTS, ABSL_TEST_COPTS, ABSL_EXCEPTIONS_FLAG, and ABSL_EXCEPTIONS_LINKOPTS
For Bazel, each BUILD file load()s configure_copts.bzl
For CMake, AbseilHelpers.cmake include()s AbseilConfigureCopts.cmake to get the final copts and both inserts them as needed into legacy target rules and also makes them available to the rest of our CMakeLists.txt file. We may instead want to include() AbseilConfigureCopts.cmake directly into each CMakeLists.txt file for consistency, but I'm not sure what the deal is with cmake and include guards, or if they are even needed. That's also not as idiomatic -- CMake tends to use directory scope where globals set at a higher level CMakeLists.txt file are used in the subdirectory CMakeLists.txt files.
