Determines whether there was an error and raises the appropriate error based on the reply code of the response
Add the install/update options to the option parser.
Add the –update-sources option
Re-composes a prime factorization and returns the product.
See Prime#int_from_prime_division for more details.
Unpacks sockaddr into path.
sockaddr should be a string or an addrinfo for AF_UNIX.
sockaddr = Socket.sockaddr_un("/tmp/sock") p Socket.unpack_sockaddr_un(sockaddr) #=> "/tmp/sock"
Counts objects size (in bytes) for each type.
Note that this information is incomplete. You need to deal with this information as only a HINT. Especially, total size of T_DATA may be wrong.
It returns a hash as:
{:TOTAL=>1461154, :T_CLASS=>158280, :T_MODULE=>20672, :T_STRING=>527249, ...}
If the optional argument, result_hash, is given, it is overwritten and returned. This is intended to avoid probe effect.
The contents of the returned hash is implementation defined. It may be changed in future.
This method is only expected to work with C Ruby.
Counts objects for each T_DATA type.
This method is only for MRI developers interested in performance and memory usage of Ruby programs.
It returns a hash as:
{RubyVM::InstructionSequence=>504, :parser=>5, :barrier=>6,
:mutex=>6, Proc=>60, RubyVM::Env=>57, Mutex=>1, Encoding=>99,
ThreadGroup=>1, Binding=>1, Thread=>1, RubyVM=>1, :iseq=>1,
Random=>1, ARGF.class=>1, Data=>1, :autoload=>3, Time=>2}
# T_DATA objects existing at startup on r32276.
If the optional argument, result_hash, is given, it is overwritten and returned. This is intended to avoid probe effect.
The contents of the returned hash is implementation specific and may change in the future.
In this version, keys are Class object or Symbol object.
If object is kind of normal (accessible) object, the key is Class object. If object is not a kind of normal (internal) object, the key is symbol name, registered by rb_data_type_struct.
This method is only expected to work with C Ruby.
Verify internal consistency.
This method is implementation specific. Now this method checks generational consistency if RGenGC is supported.
The number of paths in the ‘$LOAD_PATH` from activated gems. Used to prioritize `-I` and `ENV` entries during `require`.
Returns a String containing the API compatibility version of Ruby
Returns the latest release version of RubyGems.
Returns the version of the latest release-version of gem name
Calls wait repeatedly until the given block yields a truthy value.
Returns true if net/http is in version 1.2 mode. Defaults to true.
