CGI Utilities | |||||||
A collection of useful functions for writing 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 DODSFilter. Always choose to use that class over these functions if you can.
| |||||||
bool | do_version (const string &script_ver, const string &dataset_ver) | ||||||
Send a version number. | |||||||
void | ErrMsgT (const string &Msgt) | ||||||
Logs an error message. | |||||||
string | name_path (const string &path) | ||||||
Returns the filename portion of a pathname. | |||||||
string | rfc822_date (const time_t t) | ||||||
time_t | last_modified_time (const string &name) | ||||||
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.
| |||||||
void | set_mime_text (ostream &strm, ObjectType type, const string &ver, EncodingType enc, const time_t last_modified) | ||||||
void | set_mime_html (ostream &strm, ObjectType type, const string &ver, EncodingType enc, const time_t last_modified) | ||||||

void | read_multipart_headers (FILE *in, const string &content_type, const ObjectType object_type, const string &cid) | ||||||
void | set_mime_error (ostream &strm, int code, const string &reason, const string &version) | ||||||
void | set_mime_not_modified (ostream &strm) | ||||||

void | set_mime_text (FILE *out, ObjectType type=unknown_type, const string &version="", EncodingType enc=x_plain, const time_t last_modified=0) | ||||||
void | set_mime_html (FILE *out, ObjectType type=unknown_type, const string &version="", EncodingType enc=x_plain, const time_t last_modified=0) | ||||||
void | set_mime_binary (FILE *out, ObjectType type=unknown_type, const string &version="", EncodingType enc=x_plain, const time_t last_modified=0) | ||||||
void | set_mime_error (FILE *out, int code=404, const string &reason="Dataset not found", const string &version="") | ||||||
void | set_mime_not_modified (FILE *out) | ||||||
parse_error | |||||||
Generate error messages for the various parsers.
| |||||||
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
| |||||||
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'.
| |||||||
void | append_double_to_string (const double &num, string &str) | ||||||
string | double_to_string (const double &num) | ||||||
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 potentailly valid pathname? Test the given pathname to verfiy that it is a valid name. We define this as: Contains only printable characters; and Is less then 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. | |||||||

enum libdap::AttrType |
AttrType identifies the data types which may appear in an attribute table object.
enum AttrType { Attr_unknown, Attr_container, Attr_byte, Attr_int16, Attr_uint16, Attr_int32, Attr_uint32, Attr_float32, Attr_float64, Attr_string, Attr_url, Attr_other_xml };

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.
Definition at line 47 of file HTTPCacheDisconnectedMode.h.
enum libdap::EncodingType |
libdap understands two types of encoding: x-plain and deflate, which correspond to plain uncompressed data and data compressed with zlib's LZW algorithm respectively.
enum EncodingType { unknown_enc, deflate, x_plain, gzip, binary };
Definition at line 48 of file EncodingType.h.
enum libdap::ObjectType |
When a version 2.x or greater DAP data server sends an object, it uses the Content-Description header of the response to indicate the type of object contained in the response. During the parse of the header a member of Connect is set to one of these values so that other mfuncs can tell the type of object without parsing the stream themselves.
enum ObjectType { unknown_type, dods_das, dods_dds, dods_data, dods_error, web_error, dods_ddx, dap4_ddx, dap4_data, dap4_error, dap4_data_ddx };

void libdap::function_grid | ( | int | argc, |

DDS & | , | ||

The grid function uses a set of relational expressions to form a selection within a Grid variable based on the values in the Grid's map vectors. Thus, if a Grid has a 'temperature' map which ranges from 0.0 to 32.0 degrees, it's possible to request the values of the Grid that fall between 10.5 and 12.5 degrees without knowing to which array indexes those values correspond. The function takes one or more arguments:
<map var> <relop> <constant>
<constant> <relop> <map var> <relop> <constant>
Each of the relation expressions is applied to the Grid and the result is returned.

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 to that code can sense the end of hte DDX. In the other case, this function is told the value of boundary and tests for it to ensure document correctness.

bool libdap::rops | ( | T1 | a, |

int | op | ||

This template function is used to compare two values of two instances of the DAP2 simple types (Byte, ..., Str). The function does not take the DAP2 objects as arguments; the caller must access the values of those objects and pass them to this function. The reason for this is that all the possible functions that could be generated from this template would have to be explicitly listed as friend functions in each of the DAP2 simple type classes. In the current implementation, only the simple type classes must be friends - to see why, look at Byte::ops and note that it accesses the _buf
member of Int16, ..., Float64 and thus must be a friend of those classes.
NB: This would all be simpler if: 1) g++ supported template friend functions (without explicit listing of all the template's arguments). 2) we did not have unsigned types.

const int | line_num | ||
) |
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.

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 that values, this method sets the read_p
property for dest.
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. |
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. |
