How to install custom datastore? #257

Closed aksenofontova closed 7 years ago

aksenofontova commented 7 years ago

Hello. I'm going to use libnetconf/netopeer on my custom device. As the standard transapi doesn't cover all my needs, I have to use Custom datastore. I have read the libnetconf documentation and have scanned examples project of-config and nuci_datastore.c , but still have questions. Could you give me some help, please. After I create my custom_datastore.c, what i need to do next? Is there any standard tools for use it in netopeer? If I understood correctly, if I enter here https://github.com/CESNET/netopeer/blob/e27e01de053b296e2cacb406b76bef7b6b11f94c/server/src/server.c#L795 some desired flag, the creation and linking of a custom datastore automatically occur.

Hi, you are supposed just to call ncds_custom_set_data() function. An example code can be found in #154 or in the of-config implementation.

Hello! Thank you for answer in this issue. Could you answer a few questions, i have some problem whith understanding some functions, and your help will be very usefull for me.

  1. Where transapi/cfginterfaces project called create_datastore function ?
  2. Can I make netopeer work with custom datastore, if, for example, prescribe https://github.com/CESNET/netopeer/blob/e27e01de053b296e2cacb406b76bef7b6b11f94c/transAPI/cfginterfaces/cfginterfaces-init.c#L131 ds = ncds_new (NCDS_TYPE_CUSTOM,. ... if so, what should be done to redefine the communication functions (https://rawgit.com/CESNET/libnetconf/master/doc/doxygen/html/d0/d28/structncds__custom__funcs.html) with custom datastore ?

1) I don't understand your question.

2) You can do anything if you code it ;) But cfginterfaces-init.c is a source code for a standalone init application accessing the datastore used by the cfginterfaces transAPI plugin and storing a startup configuration data. It is not running as part of the netopeer server, it is just a single-purpose application supposed to be used once before the first start of the netopeer server with the cfginterfaces transAPi plugin

btw, if you are going to implement custom datastore, it probably does not make sense to get ideas from transAPI modules.
