Robust Services Core Versions Save

NodeBase

• Implement SlabHeap, which is expandable, and convert all object pools to use it.
• Rename NbHeap to BuddyHeap.
• Enhance the >heaps setsize command to indicate what level of restart is required to effect a heap's new size.
• Move MutexGuard to SysMutex and provide a LockGuard for SysLock.
• Register a terminate_handler on a per-thread basis, which is what Windows requires.
• Add a call to _set_abort_behavior to suppress Windows-specific behaviors when abort() is called.

CodeTools

• Support [[fallthrough]].
• Prompt the user before erasing init-only or write-only data, so that the edit can be cancelled if desired side effects would be lost.
• Fix bug: when erasing data accessed by a scope resolution, reference selection, or pointer selection operator, everything up to and including the operator was not erased.
• Reformat code to eliminate the space after/before the </> used in templates.

Known deficiencies: see Release v0.2.50.

Builds

• Move all code under src directory.
• Convert to CMake for builds.
  • Ninja builds x64 but won't take CMake's -A platform argument, so Visual Studio 17 2022 is used as the CMake generator for x86.
  • Remove .vcxproj files.
• Support builds using gcc and clang compilers.
• Fix various warnings from gcc and clang compiles.

Linux Targets

• HeapCfg: added for configuring heap sizes
• NbHeap : modified to support Linux; now used by all heaps except default heap
• SysConsole: implemented Linux target
• SysFile: made portable by converting to <filesystem> (needs C++17)

NodeBase

Documentation

• Add a "Developing an application" section to the main README.
• Update RSC Software Overview to reflect changes in this release.
• Move exe/README to docs directory and delete exe directory.

Known Deficiencies

• The Linux targets have not yet been tested, and RscLauncher still lacks a Linux target.
• RscLauncher fails, apparently because of something up-issued by VS2022.
• Recovery from std::terminate fails in a release build because of a bug in Windows code up-issued by VS2022.

NodeBase

• Invoke exit() on RestartReboot.
• Implement RscLauncher (in new launcher directory) to support RestartReboot (an automated reboot). Closes #12.
• Add missing call to AbnormalExit in Thread::Start.
• Remove omit parameter to SysThreadStack::Display.
• Change ThreadRegistry::Restarting to use a set instead of a list.
• Add #define NO_FT and use it to tag functions, replacing Debug::noft().

CodeTools

• Enhance >check to log a file that doesn't end in an endline.
• Enhance >fix to insert a missing endline at the end of a file.
• Don't log punctuation spacing on a ( at the end of a line or a } at the end of a file.
• >fix 142 f $files to append an endline to all files that are missing one.

• Fix static initialization order fiasco involving FtLocks_.
• Remove threads that have exited from FtLocks_.
• Fix displaying of context switches to account for thread identifiers no longer being contiguous.
• Fix safety net test scripts broken by recent changes.
• Reduce run-to-completion timeout to 10 msecs.
• Implement nw>ipservices command.
• Packing an enum to 8 bits can lead to a NUL in an ostringstream, with truncation when using str().
• Reduce use of ostringstream to speed up log generation.

• Support disabling/enabling of some IP services. A service is disabled by not creating its I/O thread.
• When returning from Thread.Start without deleting the thread, perform critical cleanup actions that would otherwise not occur.
• Don't throw an exception to force a thread to exit if it has already returned from Thread.Start.
• Log argument warnings even on unused functions.
• Remove pointer typedefs (TlvParmPtr, TlvParmArray) in TlvParameter.h.
• Apply >fix to various things found by >check.

• Fix bug: TCP messaging causes exceptions.
• Fix bug: Don't log socket shutdown() errors that result from race conditions.
• Enhance message display to show header and parameter lengths.
• Fix bug: nullptr should satisfy an argument that expects a function.
• Document new code files.
• Fix some C++ core guidelines warnings.
• Update copyright notices.

NodeBase

• Provide a facility for performing work after a timeout occurs (classes Deferred, DeferredRegistry, and DeferredThread).
• When a thread exits, retain its ThreadRegistry entry so that its ThreadId can appear in function traces to distinguish it from other threads.
• Don't generate a log when a thread exits normally.

NetworkBase

• Use a deferred work item to recreate I/O threads so they aren't furiously recreated when they exit because the network is down.
• Use a deferred work item to rerun the local address test if it fails.

CodeTools

• Fix bug: Editor failed to remove the first member initializer because Parser incorrectly set its position.
• Declare a virtual function that is not an override immediately after special member functions and operators.

NetworkBase

• Improve reporting of network logs and alarms (closes #44).
• Don't generate network logs when the network layer is unavailable.
• Cancel the network unavailable alarm when a socket sends or receives a message.
• Implement object pools for IpBuffer payloads (closes #48).
• Provide a SetClose function to control TCP graceful/hard close.

CodeTools

• Fix bug: when fixing FunctionCouldBeFree, Editor failed to move the function.
• Fix bug: to find the best matching function, consider the TypeMatch of all arguments instead of only the worst one.
• Fix bug: a derived class with an implicit constructor did not record an invocation of its base class default constructor, so the latter was logged as ItemCouldBePrivate.
• Fix bug: don't log ArgumentCouldBeConst on an rvalue reference argument.

NetworkBase:

• Support IPv6 (closes #33).
• Replace uses of "host" that specifically referred to the local host.
• Run preemptably when invoking getaddrinfo or getnameinfo.
• Instead of restarting, raise an alarm if SysSocket::StartLayer fails.
• Verify the local IP address during startup and raise an alarm if it fails in bind, sendto, or recvfrom.
• Implement nw>localaddr command to display the local address, with the option to re-verify it.
• Implement nw>localaddrs command to display all available local addresses.
• Implement nw>usesipv6 command to display whether IPv6 is enabled.

NodeBase:

• Rename configuration parameter GetValue functions to CurrValue and provide NextValue functions.
• Fix bug: configuration parameters that required a restart to be updated were not updated during the restart.
• Postpone raising SIGCLOSE on threads that will exit during a restart until all threads have been asked if they will exit.
• Fix bug: system hangs during restart because a thread that planned to exit missed its Proceed().
• Remove >sizes command.

CodeTools:

• Fix bug: Editor failed to make an item protected or private, and actually left it erased.
• Fix bug: CheckDebugFt cleared the database of Debug::ft function names before checking each file, which allowed duplicate function names to be used.
• Fix bug: have Editor add a new Debug::ft function name to the database of these names so that it won't be reused when editing another function.
• Fix bug: DataCouldBeFree not logged on a constant that has no references.

• If an object pool has no available blocks, expand its size immediately instead of throwing AllocationException.
• Make the default for the SourcePath configuration parameter (in input/element.config) relative to the startup directory.
• Fix some compiler warnings and code analysis warnings, and disable others.
• Provide shared/analysis.ruleset file for Windows builds that enable code analysis.

NOTE: RSC is now on VS2022, so .vcxproj files now use later versions of Windows libraries.
