acbfcef618 Add an absl::StrCat floating-point formatter absl::HighPrecision
absl::HighPrecision produces a string with enough precision that it
can be parsed back to the original floating-point value.

668f174945 Fix new -Wnullability-completeness warnings found after upgrading
the Clang version used in the Linux ARM CI to Clang 19.

nullability-completeness is an all-or-nothing warning, and it is
enabled by default. If anything is annotated, everything has to be
annotated.

There are a few types of fixes in this change. The most common is just
to add missing annotations. In a few cases, some SFINAE methods are
changed not to use pointers at all. In some cases, like
cord_internal.h, I removed the single annotation as that is easier
than doing the entire complicated file for now. cordz_test_helpers.h
uses GoogleTest macros, which bring in pointers that can't easily be
annotated, so I removed the annotations from this file as well.
Tests are also opted-out of the warning.

I'm not sure why the x86 Clang version didn't pick these issues up.

2be67701e7 Prevent brace initialization of AlphaNum
This was not intended to be supported, and it has resulted in calls as `absl::StrCat({...})`, which are not supported and only work coincidentally for the first 4 arguments due to `absl::StrCat` having overloads that take `absl::AlphaNum` directly for those.

The existing situation prevents modifying the implementations of such functions to alternatives that do not have such overloads for those arguments.

d5a2cec006 Optimize integer-to-string conversions
The updated code is designed to:
- Be branch-predictor-friendly
- Be cache-friendly
- Minimize the lengths of critical paths
- Minimize slow operations (particularly multiplications)
- Minimize binary/codegen bloat

The most notable performance trick here is perhaps the precomputation & caching of the number of digits, so that we can reuse/exploit it when writing the output.

This precomputation of the exact length enables 2 further performance benefits:
- It makes `StrCat` and `StrAppend` zero-copy when only integers are passed, by avoiding intermediate `AlphaNum` entirely in those cases. If needed in the future, we can probably also make many other mixtures of non-integer types zero-copy as well.
- It avoids over-reservation of the string buffer, allowing for more strings to fit inside SSO, which will likely have further performance benefits.

There is also a side benefit of preventing `FastIntToBuffer` from writing beyond the end of the buffer, which has caused buffer overflows in the past.

The new code continues to use & extend some of the existing core tricks (such as the division-by-100 trick), as those are already efficient.

a3d9a94325 Fix behaviors of StrCat() and StrFormat() regarding char types and enum types.
This is a conservative change, in that it only contains bugfixes and allows new patterns that used to be compile errors.  There are other changes we would like to make (as reflected in the comments in char_formatting_test.cc), but we are being careful about the implications of such behavior changes.

The two implementation changes are:
* Apply integral promotions to enums before printing them, so they are always treated as integers (and not chars) by StrCat and StrFormat.
* Classify `unsigned char` and `signed char` as integer-like rather than char-like, so that `StrFormat("%v", v)` accepts those types as integers (consistent with `StrCat()`.)

The behavior changes are:
* StrCat() now accepts char-backed enums (rather than failing to compile).
* StrFormat("%v") now accepts `signed char` and `unsigned char` as integral (rather than failing to compile).
* StrFormat("%v") now correctly formats 8-bit enums as integers (rather than failing internally and emitting nothing).

Tested:
  Modified the char_formatting_test.cc case to reflect changes.
  Re-ran all other tests.

8a0693b2a7 Adds AbslStringify support to absl::Hex and absl::Dec
`absl::Hex` and `absl::Dec` are now stringifiable through `AbslStringify`. This means that they can be passed to logging, `absl::StrFormat`, `absl::StrCat` and `absl::Substitute`. Note that this change will break unsupported usages of `absl::AlphaNum`. `absl::AlphaNum` is not intended to be instantiated as a stack variable due to lifetime issues. Unsupported usages include:

* constructing an `absl::AlphaNum` as a local variable.
  * For example, `absl::AlphaNum a = absl::Hex(...);`
* declaring an `absl::AlphaNum` as a member variable

Usage of `absl::AlphaNum` as a function parameter will continue to be supported.

If a user-defined type has `AbslStringify()` defined, it will always be used for logging over `operator<<`.

`HasAbslStringify` now uses the empty class `UnimplementedSink` for its checks instead of `StringifySink` in order to make it work in cases involving other sinks.

our compatibility guidelines which wave requirements for APIs within their
first 30 days of public release (See https://abseil.io/about/compatibility for

This CL introduces following changes to the class FlagImpl:
* We eliminate the CommandLineFlagLocks struct. Instead callback guard and callback function are combined into a single CallbackData struct, while primary data lock is stored separately.
* CallbackData member of class FlagImpl is initially set to be nullptr and is only allocated and initialized when a flag's callback is being set. For most flags we do not pay for the extra space and extra absl::Mutex now.
* Primary data guard is stored in data_guard_ data member. This is a properly aligned character buffer of necessary size. During initialization of the flag we construct absl::Mutex in this space using placement new call.
* We now avoid extra value copy after successful attempt to parse value out of string. Instead we swap flag's current value with tentative value we just produced.

two user defined conversions, which isn't allowed.
In order to accept this, we need a special constructor that
is only enabled for the bool proxy types.

Add install rules for Abseil CMake.

These are attempted to be limited to in-project installation.  This serves two purposes -- first it's morally the same as using Abseil in-source, except you don't have to rebuild us every time.  Second, the presence of an install rule makes life massively simpler for package manager maintainers.

Currently this doesn't install absl tests or testonly libraries.  This can be added in a follow-up patch.

Fixes #38, Fixes #80, Closes #182

3cdc82429af964846d1152f49148abc61d196a4b by Samuel Benzaquen <sbenza@google.com>:

Make the `long double` overload if AbslHashValue a template to avoid invalid
conversions with implicit operators.

This overload was never meant to capture anything other than `long double` and any current caller to it that wasn't a `long double` is potentially a bug.
In particular, any type with an implicit `bool` conversion is calling this
overload instead of trying to find a hash<> specialization, thus causing
pretty bad hash behavior.

Fix incorrect detection of unavailable C++17 types.

Using <any> on OS X has complications, because it is
present but marked "unavailable" due to dylib compatibility
reasons.

The dance we did to detect availability was correct
on OS X, but accidentally clobbered all other platforms
for not being Apple.

This patch corrects the detection.
