2008-08-17 Flickcurl 1.5

Added flickcurl_tags_getClusters() function for new API call flickr.tags.getClusters as announced 2008-07-17

Added Tag Clusters API support including new typedefs flickcurl_tag_cluster and flickcurl_tag_clusters and destructor function:

  void flickcurl_free_tag_clusters(flickcurl_tag_clusters *tcs);

Updated flickcurl(1) utility command to add new command tags.getClusters for calling the flickcurl_tags_getClusters() API.

Updated photo search API structure flickcurl_search_params to add contacts, has_geo, lat, lon, radius and radius_units fields.

Updated flickcurl_photos_search() to add support for new photos.search contacts, has_geo, lat, lon, radius and radius_units parameters. The lat, lon, radius and radius_units parameters were announced 2008-06-27

Updated flickrdf utility to make it build without raptor available.

2008-06-24 Flickcurl 1.4

Added video support.

Updated flickcurl(1) utility to report video information when found. Document that photos.search can now take a media argument to search over photos, videos or both.

Added a char* media type field to flickcurl_photo to allow detection of photos or videos by type, and in the case of type "video", provide extra video information in another new field flickcurl_video* video.

Added new flickcurl_video structure for providing video-specific information such as duration and flickcurl_free_video() to free it.

Added an API for turning photo description/metadata into RDF triples. Added new class flickcurl_serializer and factory flickcurl_serializer_factory for called to handle the results of serializing. Added new functions:

  flickcurl_serializer* flickcurl_new_serializer(flickcurl* fc,
    void* data, flickcurl_serializer_factory* factory);
  void flickcurl_free_serializer(flickcurl_serializer* serializer);
  int flickcurl_serialize_photo(flickcurl_serializer* frc,
    flickcurl_photo* photo);
Updated all the namespaces used by the RDF serializer to use a different use of machinetags.org as follows:
  1. Public namespaces (existing schemas):
    • Dublin Core: Prefix: dc URI: http://purl.org/dc/elements/1.1/
      legacy namespace

Updated flickrdf(1) to use new serialization API and to have less conditional code.

Fixed argument parsing bugs for the flickcurl(1) utility commands photos.search and photos.upload - 1 argument was skipped for every argument found.

flickcurl(1) utility commands photos.setContentType and photos.setSafetyLevel now accept both integer and label values.

Added a -V / --verbose flag to the flickcurl(1) utility.

Added helper functions for to/from labels for content type and safety level.

  const char* flickcurl_get_content_type_label(int content_type);
  int flickcurl_get_content_type_from_string(const char* content_type_string);
  const char* flickcurl_get_safety_level_label(int safety_level);
  int flickcurl_get_safety_level_from_string(const char* safety_level_string);

Added 1 new Flickr API call for the preferences API added to the public API around 2008-03-24.

  int flickcurl_prefs_getGeoPerms(flickcurl* fc);

Protect destructors from NULL args. In maintainer mode, a warning message and an abort happen.

Note that the woeids can be used with the new Yahoo! Geo API

4 new Flickr API calls for updates to the new flickr.prefs APIs:

  int flickcurl_prefs_getContentType(flickcurl* fc);
  int flickcurl_prefs_getHidden(flickcurl* fc);
  int flickcurl_prefs_getPrivacy(flickcurl* fc);
  int flickcurl_prefs_getSafetyLevel(flickcurl* fc);

Fixed flickcurl_photosets_create() to return properly on success. It used to do the creation correctly but failed to set up the XML XPath context so returned a failure response and error message even on success..

Fixed flickcurl photosets.create command to take 3 args not 4.

flickcurl help message was edited to use USER-NSID for NSIDs not USER-ID for user login IDs.

Added documentation section on how to do Flickr authentication.

Fixed example code and renamed it to examples/print-photo-info.c

Portability fixes for time headers.

Win32 and portability compilation fixes:

Add portable gettimeofday() which does not exist on Win32 and may not exist on non-BSD systems.

Added an implementation of the nanosleep() using either on win32: Sleep() or on unixes: sleep() and/or usleep().

Added support for place woeid field and added new photo fields PHOTO_FIELD_location_woeid, PHOTO_FIELD_neighborhood_woeid, PHOTO_FIELD_locality_woeid, PHOTO_FIELD_county_woeid, PHOTO_FIELD_region_woeid and PHOTO_FIELD_country_woeid.

2008-01-28 Flickcurl 1.2

Fixed "brown paper bag" issue. 1.1 could not be built as docs/flickcurl.1.in was missing from the tarball:

make[1]: *** No rule to make target `flickcurl.1.in', needed by `flickcurl.1'.  Stop.

Added configure search for nanosleep() in librt and libposix4 for building on Solaris.

2008-01-26 Flickcurl 1.1

2 new Flickr API calls for updates to the places APIs:

  flickcurl_place** flickcurl_places_find(flickcurl* fc, const char* query);
  flickcurl_place* flickcurl_places_findByLatLon(flickcurl* fc, double lat,
                                                 double lon, int accuracy);

Added type field to flickcurl_place structure for use by results from flickcurl_places_find().

Added method to turn a place type label into an enum:

  flickcurl_place_type flickcurl_get_place_type_by_label(const char* place_label);

Added destructor function to free list of places

  void flickcurl_free_places(flickcurl_place **places_object);

Source structure reorganised but it is building the same libraries and binaries and installing them in the same places.

Added HTML documentation API reference manual documentation automatically generated from source code autodocs, via gtkdoc. 100% of the API functions and structures are documented.

Made flickcurl manpage automatically be kept up to date with the command help from the utility itself.

Fixed a crash with the upload command of flickcurl(1)
