Detailed Description

This class is used to encapsulate the state and behavior needed for reading chunked data associated with a DAP variable. In particular it is based on the semantics of an hdf4:Chunk object, which is used to represent a chunk of data in a (potentially complex) HDF4/HDF5 file.

◆ add_tracking_query_param()

void dmrpp::Chunk::add_tracking_query_param ( )

Modify this chunk's data URL so that it includes tracking info.

Add information to the Query string of a URL, intended primarily to aid in tracking the origin of requests when reading data from S3. The information added to the query string comes from a BES Context command sent to the BES by a client (e.g., the OLFS). The addition takes the form "tracking_context=<context value>". The method checks to see if the URL already has a query string, if not it adds one: "?tracking_context=<context value>" And if so it appends an additional parameter: "&tracking_context=<context value>"

Note: This is only added to data URLs that reference an S3 bucket.; This adds a significant cost to the run-time behavior of the DMR++ code and should only be used for testing and, even then, probably rarely since the performance of the server will be reduced significantly.

Cloudydap test hack where we tag the S3 URLs with a query string for the S3 log in order to track S3 requests. The tag is submitted as a BESContext with the request. Here we check to see if the request is for an AWS S3 object, if it is AND we have the magic BESContext "cloudydap" then we add a query parameter to the S3 URL for tracking purposes.

Should this be a function? FFS why? This is the ONLY place where this needs happen, as close to the curl call as possible and we can just turn it off down the road. - ndp 1/20/17 (EOD)

Well, it's a function now... ;-) jhrg 8/6/18

Parameters

filters	Space separated list of filters
chunk_size	The expected chunk size, in elements; used to allocate storage
elem_width	The number of bytes per element

This method returns the data URL for this chunk. If the data URL is not set, it returns nullptr.

Note: The call to get_effective_url() will call EffectiveUrlCache::get_effective_url() which will call CurlUtils.cc get_redirect_url() which will call gru_mk_attempt() and will look for an HTTP 302 response and return the redirect URL in that response.

◆ set_position_in_array() [1/2]

void dmrpp::Chunk::set_position_in_array ( const std::string & pia )

parse the chunk position string

Extract information from the chunk position string and store as a vector of integers in the instance

Note: If we can change the DMR++ syntax to be less verbose and use a list of ints with whitespace as a separator, then the parsing code will be much simpler since istringstream is designed to deal with exactly that form of input.

Parameters

pia	The chunk position string. Syntax parsed: "[1,2,3,4]"

Definition at line 469 of file Chunk.cc.

◆ set_position_in_array() [2/2]

void dmrpp::Chunk::set_position_in_array ( const std::vector< unsigned long long > & pia )

Set the chunk's position in the Array.

Use this method when the vector<unsigned long long> is known.

See also: Chunk::set_position_in_array(const string &pia)

Parameters

pia	A vector of unsigned ints.

Definition at line 481 of file Chunk.cc.

◆ set_rbuf_to_size()

virtual void dmrpp::Chunk::set_rbuf_to_size ( )

inlinevirtual

Allocates the internal read buffer to be d_size bytes.

The memory of the read buffer is managed internally by this method.

The class maintains an internal flag, d_read_buffer_is_mine, which controls if the currently held read buffer memory is released (via a call to 'delete[]') when an this method is invoked.

If the CHunk owns the read buffer, then calling this method will release any previously allocated read buffer memory and then allocate a new memory block. The bytes_read counter is reset to zero.

Definition at line 503 of file Chunk.h.

◆ set_read_buffer()

void dmrpp::Chunk::set_read_buffer	(	char *	buf,
		unsigned long long	buf_size,
		unsigned long long	bytes_read = 0,
		bool	assume_ownership = true )

inline

Set the target read buffer for this chunk.

Parameters

buf	The new buffer to install into the Chunk.
buf_size	The size of the passed buffer.
bytes_read	The number of bytes that have been read into buf. In practice this is the offset in buf at which new bytes should be added, (default: 0)
assume_ownership	If true, then the memory pointed to by buf will be deleted (using delete[]) when the Chunk object's destructor is called. If false then the Chunk's destructor will not attempt to free/delete the memory pointed to by buf. (default: true)

Definition at line 531 of file Chunk.h.
