set/get secret value do not work properly

[oferb1]

I have found the following issues when testing secrets (for Ceph storage pools)

• setValue will clip the passed key
• virsh retrieves the data base64 transposed

const Promise = require('bluebird'),
      exec = Promise.promisify(require('child_process').exec),
      virt = require('libvirt'),
      uuid = require('uuid');

let secretUUID = uuid.v4(),
    secretXml =  `<secret ephemeral="no" private="no"><uuid>${secretUUID}</uuid><usage type="ceph">` +
                 '<name>client.test secret</name></usage></secret>',
    key = 'do not tell anyone',
    secret;

let hv = virt.createHypervisor('qemu:///system');

hv.connectAsync()
  .then(() => hv.defineSecretAsync(secretXml))
  .then(_secret => {
    secret = _secret;
    secret.setValueAsync(key);
  })
  .then(() => secret.getValueAsync())
  .then(value => console.log(`setValue('${key}'), while getValue() returns '${value}'`))
  .then(() => exec(`virsh secret-get-value ${secretUUID}`))
  .then(stdout => console.log(`virsh reads the secret value as '${stdout.trim()}', which is base64 transposed of the cropped key`))
  .then(() => secret.undefineAsync())
  .then(() => hv.disconnectAsync());

@oferb1 okay the SetValue bug is fixed in fcb1637. I'm not sure what you mean in the second part of your question: that virsh returns the value base64 encoded? The test I added here shows that setValue will have the same getValue, so I might make the argument that base64 encoding/decoding is up to the end user in this case (and a weird implementation detail of virsh)

[oferb1]

Thanks - I confirmed that it works, and was able to set a secret, and define a Ceph pool using it.

Still when I use virsh to read the value, I get it base64 transposed - weird...

[mbroadst]

Still not sure what you mean about "transposed" in this case. Can you use node-libvirt to check if virsh is converting to base64 on the way in or out? like store it with virsh and read with node-libvirt and visa versa

virsh set value

Secret value set

node-libvirt get value

hv.lookupSecretByUUIDAsync('a14408e2-e147-4ce9-b081-fd56ffab8e48').then(secret => secret.getValueAsync()).then(console.log)
