1 This is meant to be a general place to list things that should be done "someday" 2 3 CXX Runtime Library Tasks 4 ========================= 5 * Fix that CMake always link to /usr/lib/libc++abi.dylib on OS X. 6 * Look into mirroring libsupc++'s typeinfo vtable layout when libsupc++/libstdc++ 7 is used as the runtime library. 8 * Investigate and document interoperability between libc++ and libstdc++ on 9 linux. Do this for every supported c++ runtime library. 10 11 Atomic Related Tasks 12 ==================== 13 * future should use <atomic> for synchronization. 14 15 Test Suite Tasks 16 ================ 17 * Improve the quality and portability of the locale test data. 18 * Convert failure tests to use Clang Verify. 19 20 Filesystem Tasks 21 ================ 22 * P0492r2 - Implement National body comments for Filesystem 23 * INCOMPLETE - US 25: has_filename() is equivalent to just !empty() 24 * INCOMPLETE - US 31: Everything is defined in terms of one implicit host system 25 * INCOMPLETE - US 32: Meaning of 27.10.2.1 unclear 26 * INCOMPLETE - US 33: Definition of canonical path problematic 27 * INCOMPLETE - US 34: Are there attributes of a file that are not an aspect of the file system? 28 * INCOMPLETE - US 35: What synchronization is required to avoid a file system race? 29 * INCOMPLETE - US 36: Symbolic links themselves are attached to a directory via (hard) links 30 * INCOMPLETE - US 37: The term redundant current directory (dot) elements is not defined 31 * INCOMPLETE - US 38: Duplicates 17.3.16 32 * INCOMPLETE - US 39: Remove note: Dot and dot-dot are not directories 33 * INCOMPLETE - US 40: Not all directories have a parent. 34 * INCOMPLETE - US 41: The term parent directory for a (non-directory) file is unusual 35 * INCOMPLETE - US 42: Pathname resolution does not always resolve a symlink 36 * INCOMPLETE - US 43: Concerns about encoded character types 37 * INCOMPLETE - US 44: Definition of path in terms of a string requires leaky abstraction 38 * INCOMPLETE - US 45: Generic format portability compromised by unspecified root-name 39 * INCOMPLETE - US 46: filename can be empty so productions for relative-path are redundant 40 * INCOMPLETE - US 47: . and .. already match the name production 41 * INCOMPLETE - US 48: Multiple separators are often meaningful in a root-name 42 * INCOMPLETE - US 49: What does method of conversion method mean? 43 * INCOMPLETE - US 50: 27.10.8.1 1.4 largely redundant with 1.3 44 * INCOMPLETE - US 51: Failing to add / when appending empty string prevents useful apps 45 * INCOMPLETE - US 52: remove_filename() postcondition is not by itself a definition 46 * INCOMPLETE - US 53: remove_filename()'s name does not correspond to its behavior 47 * INCOMPLETE - US 54: remove_filename() is broken 48 * INCOMPLETE - US 55: replace_extension()'s use of path as parameter is inappropriate 49 * INCOMPLETE - US 56: Remove replace_extension()'s conditional addition of period 50 * INCOMPLETE - US 57: On Windows, absolute paths will sort in among relative paths 51 * INCOMPLETE - US 58: parent_path() behavior for root paths is useless 52 * INCOMPLETE - US 59: filename() returning path for single path components is bizarre 53 * INCOMPLETE - US 60: path("/foo/").filename()==path(".") is surprising 54 * INCOMPLETE - US 61: Leading dots in filename() should not begin an extension 55 * INCOMPLETE - US 62: It is important that stem()+extension()==filename() 56 * INCOMPLETE - US 63: lexically_normal() inconsistently treats trailing "/" but not "/.." as directory 57 * INCOMPLETE - US 73, CA 2: root-name is effectively implementation defined 58 * INCOMPLETE - US 74, CA 3: The term pathname is ambiguous in some contexts 59 * INCOMPLETE - US 75, CA 4: Extra flag in path constructors is needed 60 * INCOMPLETE - US 76, CA 5: root-name definition is over-specified. 61 * INCOMPLETE - US 77, CA 6: operator/ and other appends not useful if arg has root-name 62 * INCOMPLETE - US 78, CA 7: Member absolute() in 27.10.4.1 is overspecified for non-POSIX-like O/S 63 * INCOMPLETE - US 79, CA 8: Some operation functions are overspecified for implementation-defined file types 64 * INCOMPLETE - US 185: Fold error_code and non-error_code signatures into one signature 65 * INCOMPLETE - FI 14: directory_entry comparisons are members 66 * INCOMPLETE - Late 36: permissions() error_code overload should be noexcept 67 * INCOMPLETE - Late 37: permissions() actions should be separate parameter 68 * INCOMPLETE - Late 42: resize_file() Postcondition missing argument 69 70 Misc Tasks 71 ========== 72 * Find all sequences of >2 underscores and eradicate them. 73 * run clang-tidy on libc++ 74 * Document the "conditionally-supported" bits of libc++ 75 * Look at basic_string's move assignment operator, re LWG 2063 and POCMA 76 * Put a static_assert in std::allocator to deny const/volatile types (LWG 2447) 77
