Results for: "partition"

Creates or an HTTP connection based on uri, or retrieves an existing connection, using a proxy if needed.

possible opt elements:

hash form:
  :partial_input => true           # source buffer may be part of larger source
  :after_output => true            # stop conversion after output before input
integer form:
  Encoding::Converter::PARTIAL_INPUT
  Encoding::Converter::AFTER_OUTPUT

possible results:

:invalid_byte_sequence
:incomplete_input
:undefined_conversion
:after_output
:destination_buffer_full
:source_buffer_empty
:finished

primitive_convert converts source_buffer into destination_buffer.

source_buffer should be a string or nil. nil means an empty string.

destination_buffer should be a string.

destination_byteoffset should be an integer or nil. nil means the end of destination_buffer. If it is omitted, nil is assumed.

destination_bytesize should be an integer or nil. nil means unlimited. If it is omitted, nil is assumed.

opt should be nil, a hash or an integer. nil means no flags. If it is omitted, nil is assumed.

primitive_convert converts the content of source_buffer from beginning and store the result into destination_buffer.

destination_byteoffset and destination_bytesize specify the region which the converted result is stored. destination_byteoffset specifies the start position in destination_buffer in bytes. If destination_byteoffset is nil, destination_buffer.bytesize is used for appending the result. destination_bytesize specifies maximum number of bytes. If destination_bytesize is nil, destination size is unlimited. After conversion, destination_buffer is resized to destination_byteoffset + actually produced number of bytes. Also destination_buffer’s encoding is set to destination_encoding.

primitive_convert drops the converted part of source_buffer. the dropped part is converted in destination_buffer or buffered in Encoding::Converter object.

primitive_convert stops conversion when one of following condition met.

• invalid byte sequence found in source buffer (:invalid_byte_sequence) primitive_errinfo and last_error methods returns the detail of the error.

• unexpected end of source buffer (:incomplete_input) this occur only when :partial_input is not specified. primitive_errinfo and last_error methods returns the detail of the error.

• character not representable in output encoding (:undefined_conversion) primitive_errinfo and last_error methods returns the detail of the error.

• after some output is generated, before input is done (:after_output) this occur only when :after_output is specified.

• destination buffer is full (:destination_buffer_full) this occur only when destination_bytesize is non-nil.

• source buffer is empty (:source_buffer_empty) this occur only when :partial_input is specified.

• conversion is finished (:finished)

example:

ec = Encoding::Converter.new("UTF-8", "UTF-16BE")
ret = ec.primitive_convert(src="pi", dst="", nil, 100)
p [ret, src, dst] #=> [:finished, "", "\x00p\x00i"]

ec = Encoding::Converter.new("UTF-8", "UTF-16BE")
ret = ec.primitive_convert(src="pi", dst="", nil, 1)
p [ret, src, dst] #=> [:destination_buffer_full, "i", "\x00"]
ret = ec.primitive_convert(src, dst="", nil, 1)
p [ret, src, dst] #=> [:destination_buffer_full, "", "p"]
ret = ec.primitive_convert(src, dst="", nil, 1)
p [ret, src, dst] #=> [:destination_buffer_full, "", "\x00"]
ret = ec.primitive_convert(src, dst="", nil, 1)
p [ret, src, dst] #=> [:finished, "", "i"]

Returns a new Fiddle::Function instance at the memory address of the given name function.

Raises a DLError if the name doesn’t exist.

• argtype is an Array of arguments, passed to the name function.

• ctype is the return type of the function

• call_type is the ABI of the function

Parses multipart form elements according to

http://www.w3.org/TR/html401/interact/forms.html#h-17.13.4.2

Returns a hash of multipart form parameters with bodies of type StringIO or Tempfile depending on whether the multipart form element exceeds 10 KB

params[name => body]

Generate a Form element with multipart encoding as a String.

Multipart encoding is used for forms that include file uploads.

action is the action to perform. enctype is the encoding type, which defaults to “multipart/form-data”.

Alternatively, the attributes can be specified as a hash.

multipart_form{ "string" }
  # <FORM METHOD="post" ENCTYPE="multipart/form-data">string</FORM>

multipart_form("url") { "string" }
  # <FORM METHOD="post" ACTION="url" ENCTYPE="multipart/form-data">string</FORM>

If –yjit-trace-exits is enabled parse the hashes from Primitive.rb_yjit_get_exit_locations into a format readable by Stackprof. This will allow us to find the exact location of a side exit in YJIT based on the instruction that is exiting.

Execute the provided block, but preserve the exception mode

BigDecimal.save_exception_mode do
  BigDecimal.mode(BigDecimal::EXCEPTION_OVERFLOW, false)
  BigDecimal.mode(BigDecimal::EXCEPTION_NaN, false)

  BigDecimal(BigDecimal('Infinity'))
  BigDecimal(BigDecimal('-Infinity'))
  BigDecimal(BigDecimal('NaN'))
end

For use with the BigDecimal::EXCEPTION_*

See BigDecimal.mode

Raises PStore::Error if the calling code is not in a PStore#transaction or if the code is in a read-only PStore#transaction.

Yields each frame of the current execution stack as a backtrace location object.

Starts tracing object allocations from the ObjectSpace extension module.

For example:

require 'objspace'

class C
  include ObjectSpace

  def foo
    trace_object_allocations do
      obj = Object.new
      p "#{allocation_sourcefile(obj)}:#{allocation_sourceline(obj)}"
    end
  end
end

C.new.foo #=> "objtrace.rb:8"

This example has included the ObjectSpace module to make it easier to read, but you can also use the ::trace_object_allocations notation (recommended).

Note that this feature introduces a huge performance decrease and huge memory consumption.

Returns the method identifier for the given object.

class A
  include ObjectSpace

  def foo
    trace_object_allocations do
      obj = Object.new
      p "#{allocation_class_path(obj)}##{allocation_method_id(obj)}"
    end
  end
end

A.new.foo #=> "Class#new"

See ::trace_object_allocations for more information and examples.

Sets whether or not to ignore case on completion.

Returns true if completion ignores case. If no, returns false.

NOTE: Returns the same object that is specified by Readline.completion_case_fold= method.

require "readline"

Readline.completion_case_fold = "This is a String."
p Readline.completion_case_fold # => "This is a String."

The file name and line number of the caller of the caller of this method.

depth is how many layers up the call stack it should go.

e.g.,

def a; Gem.location_of_caller; end a #=> [“x.rb”, 2] # (it’ll vary depending on file name and line number)

def b; c; end def c; Gem.location_of_caller(2); end b #=> [“x.rb”, 6] # (it’ll vary depending on file name and line number)

Path to specification files of default gems.

Creates an option parser and fills it in with the help info for the command.

True if the gems in the system satisfy dependency.
