2024-09-25libstdc++: #ifdef out #pragma GCC system_headerJason Merrill
In r15-3714-gd3a7302ec5985a I added -Wsystem-headers to the libstdc++ build flags to help catch problems in the library. This patch takes a different approach, of disabling the #pragma system_header unless _GLIBCXX_SYSHDR is defined. As a result, the testsuites will treat them as non-system-headers to get better warning coverage during regression testing of both gcc and libstdc++, not just when building the library. My rationale for the #ifdef instead of just removing the #pragma is the three G++ tests that want to test libstdc++ system header behavior, so we need a way to select it. This doesn't affect installed libraries, as they get their system-header status from the lookup path. But testsuite_flags --build-includes gives -I directives rather than -isystem. This patch doesn't change the headers in config/ because I'm not compiling with most of them, so won't see any warnings that need fixing. Adjusting them could happen later, or we can not bother. libstdc++-v3/ChangeLog: * acinclude.m4 (WARN_FLAGS): Remove -Wsystem-headers. * configure: Regenerate. * include/bits/algorithmfwd.h: #ifdef

2023-11-04libstdc++: Use strerror_r in std::generic_category()::message(int) [PR110133]Jonathan Wakely
Use strerror_r instead of strerror when available, due to the latter not being thread-safe. This is complicated by Glibc providing a GNU-specific strerror_r which is not compatible with POSIX strerror_r, so we need to dispatch on the return type. We can use the recently-added std::string::__resize_and_overwrite to write directly into the string buffer when possible. Because we estimate the initial buffer size we might end up with excess capacity in the returned std::string. We can slightly tweak the std::system_error constructors to make use of that excess capacity, so that in some cases we require fewer allocations to construct the std::system_error::what() string. libstdc++-v3/ChangeLog: PR libstdc++/110133 * include/std/system_error (system_error::system_error): Group arguments so that concatenation can reuse rvalue's capacity. * src/c++11/system_error.cc (strerror_string): New function. [_GLIBCXX_HAVE_STRERROR_R] (use_strerror_result): New functions. (generic_error_category::message): Use strerror_string. (system_error_category::message): Likewise.

2022-09-08libstdc++: Find make_error_code and make_error_condition via ADL onlyJonathan Wakely
The new proposed resolution for LWG 3629 says that std::error_code and std::error_condition should only use ADL to find their customization points. This means we need to use a poison pill to prevent lookup from finding overloads in the enclosing namespaces. We can also remove the forward declarations of std::make_error_code and std::make_error_condition, because they aren't needed now. ADL can find them anyway (when std is an associated namespace), and unqualified name lookup will not (and should not) find them. libstdc++-v3/ChangeLog: * include/std/system_error (__adl_only::make_error_code): Add deleted function. (__adl_only::make_error_condition): Likewise. (error_code::error_code(ErrorCodeEnum)): Add using-declaration for deleted function.

2022-08-26libstdc++: Simplify std::error_code and std::error_conditionJonathan Wakely
This removes the redundant operator=(E) from std::error_code and std::error_condition. Without that overload, assignment from a custom type will use the templated constructor to create a temporary and then use the trivial copy assignment operator. With the overloaded assignment, we have to check the constraints twice as often, because that overload and its constraints are checked for simple copy assignments (including the one in the overloaded assignment operator itself!) Also add tests that ADL is used as per LWG 3629. libstdc++-v3/ChangeLog: * include/std/system_error (error_code::_Check): New alias template for constructor SFINAE constraint. (error_code::error_code(ErrorCodeEnum)): Use it. (error_code::operator=(ErrorCodeEnum)): Remove. (error_condition::_Check): New alias template for constraint.

2022-05-13libstdc++: Add macros for the inline namespace std::_V2Jonathan Wakely
Use macros to open and close the inline namespace _V2 that is used for ABI versioning of individual components such as chrono::system_clock. This allows the namespace to be hidden in the docs generated by Doxygen, so that we document std::foo instead of std::_V2::foo. This also makes it easy to remove that namespace entirely for the gnu-versioned-namespace build, where everything is already versioned as std::__8 and there are no backwards compatibility guarantees. libstdc++-v3/ChangeLog: * doc/doxygen/user.cfg.in (PREDEFINED): Expand new macros to nothing. * include/bits/c++config (_GLIBCXX_BEGIN_INLINE_ABI_NAMESPACE) (_GLIBCXX_END_INLINE_ABI_NAMESPACE): Define new macros. * include/bits/algorithmfwd.h (_V2::__rotate): Use new macros for the namespace. * include/bits/chrono.h (chrono::_V2::system_clock): Likewise. * include/bits/stl_algo.h (_V2::__rotate): Likewise. * include/std/condition_variable (_V2::condition_variable_any): Likewise. * include/std/system_error (_V2::error_category): Likewise.

2021-07-01libstdc++: Improvements to Doxygen markupJonathan Wakely
This attempst to improve the doxygen output to work around what seems to be some bugs in doxygen (issues 8635 and 8638). The @addtogroup command doesn't work for entities inside a nested namespace (see 8635) so we need to close and reopen groups on entering and elaving nested namespaces. This fixes the problem that chrono::duration and chrono::time_point were not documented in the "Time" documentation group. I am unable to make the path classes appear as part of their relevant groups (File System and Filesystem TS), nor the contents of <exception> or <system_error>. I have made some minor improvements to the docs for those types, including starting to address PR 97001 by adding @since to the doxygen comments. This change also excludes the <experimental/bits/net.h> header from Doxygen processing, so we don't get an unwanted "Networking-ts" group in the documentation.
