class	chunked_inbuf

class	chunked_istream

class	chunked_ostream
	A C++ stream class for chunked data. This class uses the chunked_outbuf class to provide for chunked binary serialization of data as specified by DAP4. Information to be serialized is broken into 'chunks' that are no more than 2^24 bytes in length. Each chunk is prefixed by a 4 byte header that indicates the type of chunk and size (number of bytes in the chunk body). There are three types of chunk: Data; End; and Error. In normal operation, a DAP4 data document/response is serialized as a sequence of DATA chunks followed by one END chunk (which may be zero bytes in length). If, during serialization, an error is detected, the currently buffered (but not sent) data are discarded and an ERROR chunk is sent with an error message. More...

class	chunked_outbuf
	output buffer for a chunked stream This performs buffered output encoding the data in the stream using the simple chunking protocol defined for DAP4's binary data transmission. Each block of data is prefixed by four bytes: A CHUNK TYPE byte followed by three bytes that are the CHUNK SIZE. There are three CHUNK TYPES: data, end and error, indicated by the code values 0x00, 0x01 and 0x02. The size of a chunk is limited to 2^24 data bytes + 4 bytes for the chunk header. More...

MIME Utilities

A collection of useful functions for writing MIME headers for OPeNDAP servers.

The CGI utilities include a variety of functions useful to programmers developing OPeNDAP CGI filter programs. However, before jumping in and using these, look at the class ResponseBuilder. Always choose to use that class over these functions if you can. Many of these functions were used by the CGI programs that made up the first DAP server; all of those are deprecated and the ResponseBuilder class should be used instead. Some of the other functions are used by ResponseBuilder and the client-side parsing code that needs to identify MIME headers, boundaries, etc.

void remove_mime_header (istream &in)

MIME utility functions

These functions are used to create the MIME headers for a message from a server to a client. They are public but should not be called directly unless absolutely necessary. Use DODSFilter instead.

NB: These functions actually write both the response status line and the header.

Deprecated: Use ResponseBuilder instead.

parse_error

Generate error messages for the various parsers.

parser_error() generates error messages for the various parsers used by libdap. There are two versions of the function, one which takes a const char *message and a const int line_num and writes the message and line number too stderr and a second which takes an additional parser_arg arg parameter and writes the error message into an Error object which is returned to the caller via the arg parameter.

Note: {The second version of this function also accepts a third parameter (const char *context) which can be used to provide an additional line of information beyond what is in the string message.}

Returns: void

void parse_error (parser_arg *arg, const char *msg, const int line_num, const char *context)

void parse_error (const string &msg, const int line_num, const char *context)

Integer to string conversion functions

Fast, safe conversions from long to a character representation which gets appended to a string. This method will take a long value 'val' and it will recursively divide it by 'base' in order to "extract" one by one the digits which compose it; these digits will be appended to the string str_val which will become the textual representation of 'val'. Please notice that the digits `‘extracted’' from ‘val’ will vary depending on the base chosen for the conversion; for example val=15 converted to base 10 will yield the digits (1,5), converted to base 16 will yield (F) and converted to base 2 will yield (1,1,1,1).

Parameters

val	The long value we which to convert to string.
base	A value in the range [2,36] which is the base to use while transforming the long value 'val' to its textual representation. Typical bases are 2 (binary), 10 (decimal) and 16 (hexadecimal).
str_val	This is the string that will hold the textual representation of 'val'. The string `str_val` should be pre-set to an empty string ("") otherwise the output of this function will just append the textual representation of val to whatever data is there; these feature may be useful if you wish to append a long value to a string s1 (just like operator+ does) without having to create a new string object s2 and then use string::operator+ between s1 and s2.

Returns: void. This method returns nothing however be aware that it will throw and exception of type std::invalid_argument if the parameter base is not in the valid range.

void append_long_to_string (long val, int base, string &str_val)

string long_to_string (long val, int base)

Double to string conversion functions

Conversions from double to a character representation which gets appended to a string. This function depends on the standard routine sprintf to convert a double to a textual representation which gets appended to the string 'str'.

Parameters

num	The double you wish to append to str.
str	The string where the textual representation of num will be appended.

Returns: void.

void append_double_to_string (const double &num, string &str)

string double_to_string (const double &num)

string path_to_filename (string path)

int glob (const char *c, const char *s)

time_t parse_time (const char *str, bool expand)

Security functions

bool size_ok (unsigned int sz, unsigned int nelem)

sanitize the size of an array. Test for integer overflow when dynamically allocating an array.

bool pathname_ok (const string &path, bool strict)

Does the string name a potentially valid pathname? Test the given pathname to verify that it is a valid name. We define this as: Contains only printable characters; and Is less than 256 characters. If strict is true, test that the pathname consists of only letters, digits, and underscore, dash and dot characters instead of the more general case where a pathname can be composed of any printable characters.

◆ CacheDisconnectedMode

enum libdap::CacheDisconnectedMode

Disconnected Operation

The cache can be set to handle disconnected operation where it does not use the network to validate entries and does not attempt to load new documents. All requests that cannot be fulfilled by the cache will be returned with a "504 Gateway Timeout" response. There are two operational disconnected modes:

No network activity at all: Here it uses its own persistent cache to answer the request, if possible.

Forward all disconnected requests to a proxy cache: Here it uses the HTTP/1.1 cache-control header to indicate that the proxy should operate in disconnected mode.

◆ path_to_filename()

string libdap::path_to_filename ( string path )

Get the filename part from a path. This function can be used to return a string that has the directory components stripped from a path. This is useful when building error message strings.

If WIN32 is defined, use '\' as the path separator, otherwise use '/' as the path separator.

Returns: A string containing only the filename given a path.

Definition at line 988 of file util.cc.

◆ pathname_ok()

bool libdap::pathname_ok	(	const string &	path,
		bool	strict )

Does the string name a potentially valid pathname? Test the given pathname to verify that it is a valid name. We define this as: Contains only printable characters; and Is less than 256 characters. If strict is true, test that the pathname consists of only letters, digits, and underscore, dash and dot characters instead of the more general case where a pathname can be composed of any printable characters.

Note: Using this function does not guarantee that the path is valid, only that the path could be valid. The intent is foil attacks where an exploit is encoded in a string then passed to a library function. This code does not address whether the pathname references a valid resource.

Parameters

path	The pathname to test
strict	Apply more restrictive tests (true by default)

Returns: true if the pathname consists of legal characters and is of legal size, false otherwise.

boundary	Value of the boundary to look for - optional
in	Read from this FILE*

Returns: The value of the boundary header read

Exceptions

Error if no boundary was found.

◆ read_multipart_headers() [1/2]

void libdap::read_multipart_headers	(	FILE *	in,
		const string &	content_type,
		const ObjectType	object_type,
		const string &	cid )

Consume the Multipart MIME headers that prefix the DDX in a DataDDX response. The stream pointer is advanced to the start of the DDX. It might seem odd that this function both takes the value of the MPM boundary as a parameter and returns that value as a result, but this code can be used in two different situations. In one case, it is called on a partial document read from stdin and needs to return the value of boundary to the downstream DDX parser so that code can sense the end of the DDX. In the other case, this function is told the value of boundary and tests for it to ensure document correctness.

Parameters

in	Read from this stream
content_type	The expected value of the Content-Type header
object_type	The expected value of the Content-Description header
cid	The expected value of the Content-Id header - optional.

Returns: The value of the MIME boundary

Exceptions

Error if the boundary is not found or if any of the expected header values don't match. The optional values are tested only if they are given (the default values are not tested).

◆ save_str()

void libdap::save_str	(	std::string &	dst,
		const char *	src,

Save a string to a temporary variable during the parse.

Given a string (const char *src), save it to the temporary variable pointed to by dst. If the string is longer than ID_MAX, generate and error indicating that src was truncated to ID_MAX characters during the copy operation. There are two versions of this function; one calls the version of parser_error() which writes to stderr. The version which accepts the parser_arg *arg argument calls the version of parser_error() which generates and Error object.

Returns: void

◆ set_array_using_double()

void libdap::set_array_using_double	(	Array *	dest,
		double *	src,
		int	src_len )

Given an array that holds some sort of numeric data, load it with values using an array of doubles. This function makes several assumptions. First, it assumes the caller really wants to put the doubles into whatever types the array holds! Caveat emptor. Second, it assumes that if the size of source (src) array is different than the destination (dest) the caller has made a mistake. In that case it will throw an Error object.

After setting the values, this method sets the read_p property for dest. Setting read_p tells the serialization methods in libdap that this variable already holds data values and, given that, the serialization code will not try to read the values.

Note: Support for DAP4 added.

Parameters

dest	An Array. The values are written to this array, reusing its storage. Existing values are lost.
src	The source data.
src_len	The number of elements in the src array.

Exceptions

Error Thrown if dest is not a numeric-type array (Byte, ..., Float64) or if the number of elements in src does not match the number is dest.

		const string &	escape,
		const string &	except )

Given a string that contains WWW escape sequences, translate those escape sequences back into the ASCII characters they represent. Return the modified string.

-Places in the dap code where www2id() is called:

Array::append_dim() the name is decoded before it is added
AttrTable::set_name(), AttrTable::append_attr(), AttrTable::append_container(), AttrTable::del_attr(), AttrTable::add_container_alias(), AttrTable::add_value_alias() names are decoded before that are set/used.
BaseType::set_name() Names are decoded before they are set
When the constraint expression parser looks for a variable, the name is first decoded.
DAS::DAS() Named attribute containers are decoded
DDS::var() When a DDS searches for a variable, the name is first decoded.
Grid::var(), Sequence::var(), Structure::var() Variable names are decoded.

-In the server code:

ResponseBuilder::initialize() The dataset name is decoded except that %20 is not removed.
ResponseBuilder::set_ce() The CE is decoded, except for spaces (%20).
ResponseBuilder::set_dataset_name() same logic as the first case.
The ResponseBuilder methods supersede methods with the same names from DODSFilter, which is still in the code although deprecated.

Parameters

in	The string to modify.
escape	The character used to signal the beginning of an escape sequence. default: "%"
except	If there are some escape codes that should not be removed by this call (e.g., you might not want to remove spaces, %20) use this parameter to specify those codes. The function will then transform all escapes except those given. For example, to suppress translation of both spaces and the ampersand, pass "%20%26" for 'except'. default: ""

Returns: The modified string.

Definition at line 202 of file escaping.cc.

◆ xml2id()

string libdap::xml2id ( string in )

Given a string that contains XML escape sequences (i.e., entities), translate those back into ASCII characters. Return the modified string.

Parameters

in	The string to modify.

Returns: The modified string.
