Detailed Description

Compile-time constraint and validation utilities for jh::sync::ipc.

This namespace provides consteval-based helpers used to validate IPC object names and POSIX-style relative paths at compile time. It is an internal support layer and not intended for direct runtime use.

Function Documentation

valid_object_name()

template<jh::meta::TStr S, std::uint64_t MaxLen = max_name_length>

bool jh::sync::ipc::limits::valid_object_name ( )

consteval

Validate compile-time IPC object name (for semaphores, shared memory, etc.).

Rules

• Length must be in range [1, MaxLen], default = 30 (BSD limit).
• Allowed characters: [A-Za-z0-9_.-].
• No leading '/' (automatically added by the OS namespace).

Template parameters

• S — compile-time string representing base name.
• MaxLen — optional override for system-specific maximum name length.

Returns

true if the name is valid, otherwise false.

valid_relative_path()

template<jh::meta::TStr S>

bool jh::sync::ipc::limits::valid_relative_path ( )

constevalnoexcept

Compile-time validation for POSIX-style relative paths.

Rules

• Length in range [1, 128].
• Absolute paths forbidden (no leading '/').
• No "./" segments.
• ".." segments:
  • When JH_INTERPROCESS_ALLOW_PARENT_PATH == 0 → forbidden.
  • When JH_INTERPROCESS_ALLOW_PARENT_PATH == 1 → leading "../" allowed but cannot occupy entire path, and no ".." after content begins.
• Allowed characters: [A-Za-z0-9_.-/].
