RELEASE NOTES for qore v0.8.2

release summary: 16 bug fixes, IPv6 support, and other minor improvements

• BUG FIX: fixed a crash when calling exit() right after fork() in the parent process by ensuring that the signal thread is stopped before exit()ing
• BUG FIX: fixed parse option inheritance with Program objects; when PO_NO_CHILD_PO_RESTRICTIONS is set, then take the parse option argument to Program::constructor() and apply them literally to the new Program object (before the parse options were ignored and the parse options applied to the child were applied from unitialized memory)
• BUG FIX: fixed a memory/reference leak in the remove operator
• BUG FIX: fixed a bug initializing the internal signal manager related to static C++ initialization ordering
• BUG FIX: fixed some bugs with %new-style with variable declaration lists
• BUG FIX: fixed typos in statvfs hash output
• BUG FIX: fixed constant resolution when a class constant refers to other (unscoped) class constants in the constant's definition
• BUG FIX: fixed catch block parameter parsing when %allow-bare-refs is set
• BUG FIX: Dir::openFile() return type corrected to "File"
• BUG FIX: fixed memory errors merging in exception thrown when executing code at parse time to the run-time exception sink
• BUG FIX: fixed initializing case expressions requiring parse-time evaluation
• BUG FIX: fixed the SQLStatement class to perform an auto-commit if necessary when the statement is closed when used with a Datasource with auto-commit enabled
• BUG FIX: fixed (with an override) RWLock::lockOwner() to return True if the read lock is held
• BUG FIX: the SQLStatement class did not set the "in transaction" flag when executing SQL; this could cause the transaction state to be silently lost when a driver does a reconnect with a lost connection
• BUG FIX: the internal c++ Datasource class did not set the "active transaction" flag properly with the first exec
• BUG FIX: added -lthread to sparc8 builds
• new feature: IPv6 support: Socket class updated, parseURL(), and parse_url() updated to work with IPv6 addresses and hostnames
• new feature: added Socket::getPeerInfo() and Socket::getSocketInfo() methods to get verbose information about local and remote sockets
• new feature: getaddrinfo() function and related constants to get network address information for hostnames and services
• new feature: added statvfs() function
• new feature: added normal methods: Dir::hstat(), Dir::stat(), Dir::statvfs()
• new feature: added normal methods: File::stat(), File::hstat(), File::statvfs(); added static methods: File::stat(), File::lstat(), File::hstat(), File::hlstat(), File::statvfs()
• new feature: added the %y printf format specifier to give YAML-like output for complex data structures
• new feature: added RWLock::writeLockOwner() and RWLock::readLockOwner() methods
• new feature: added date_info() function with 2 variants to get broken-down date/time information
• new feature: added FtpClient::rename() method
• new feature: removed restriction assigning function references to constants
• new feature: added trunc_str() function for more efficient trimming a multi-byte string to a certain maximum byte length
• new feature: added a new DBI method: selectRow() and capability (DBI_CAP_HAS_SELECT_ROW); this allows drivers to efficiently select only one row from a select statement; if more than one row is returned, then an exception should be raised and the data not actually returned from the DB server; if the DBI driver does not implement this function, then the Qore library will emulate this behavior with selectRows()
• new feature: added timestamp to default exception handler output
• new feature: when the debugging compile-time option is enabled, then simple backtraces are supported in specific places that will assert on Linux and OSX
• doc updates: content was added for new and existing features and corrections were made
