Receive UDP/IP packets from the given sockets. For each packet received, the block is called.
The block receives msg and msg_src. msg is a string which is the payload of the received packet. msg_src is a Socket::UDPSource object which is used for reply.
Socket.udp_server_loop can be implemented using this method as follows.
udp_server_sockets(host, port) {|sockets|
loop {
readable, _, _ = IO.select(sockets)
udp_server_recv(readable) {|msg, msg_src| ... }
}
}
Return the native thread ID which is used by the Ruby thread.
The ID depends on the OS. (not POSIX thread ID returned by pthread_self(3))
On Linux it is TID returned by gettid(2).
On macOS it is the system-wide unique integral ID of thread returned by pthread_threadid_np(3).
On FreeBSD it is the unique integral ID of the thread returned by pthread_getthreadid_np(3).
On Windows it is the thread identifier returned by GetThreadId().
On other platforms, it raises NotImplementedError.
NOTE: If the thread is not associated yet or already deassociated with a native thread, it returns nil. If the Ruby implementation uses M:N thread model, the ID may change depending on the timing.
Add the install/update options to the option parser.
Starts tracing object allocations.
Stop tracing object allocations.
Note that if ::trace_object_allocations_start is called n-times, then tracing will stop after calling ::trace_object_allocations_stop n-times.
Returns a URL-encoded string derived from the given string str.
The returned string:
Preserves:
Characters '*', '.', '-', and '_'.
Character in ranges 'a'..'z', 'A'..'Z', and '0'..'9'.
Example:
URI.encode_www_form_component('*.-_azAZ09') # => "*.-_azAZ09"
Converts:
Character ' ' to character '+'.
Any other character to “percent notation”; the percent notation for character c is '%%%X' % c.ord.
Example:
URI.encode_www_form_component('Here are some punctuation characters: ,;?:') # => "Here+are+some+punctuation+characters%3A+%2C%3B%3F%3A"
Encoding:
If str has encoding Encoding::ASCII_8BIT, argument enc is ignored.
Otherwise str is converted first to Encoding::UTF_8 (with suitable character replacements), and then to encoding enc.
In either case, the returned string has forced encoding Encoding::US_ASCII.
Related: URI.encode_uri_component (encodes ' ' as '%20').
Returns a string decoded from the given URL-encoded string str.
The given string is first encoded as Encoding::ASCII-8BIT (using String#b), then decoded (as below), and finally force-encoded to the given encoding enc.
The returned string:
Preserves:
Characters '*', '.', '-', and '_'.
Character in ranges 'a'..'z', 'A'..'Z', and '0'..'9'.
Example:
URI.decode_www_form_component('*.-_azAZ09') # => "*.-_azAZ09"
Converts:
Character '+' to character ' '.
Each “percent notation” to an ASCII character.
Example:
URI.decode_www_form_component('Here+are+some+punctuation+characters%3A+%2C%3B%3F%3A') # => "Here are some punctuation characters: ,;?:"
Related: URI.decode_uri_component (preserves '+').
