/*
|
|
Design of this:
|
|
|
|
The idea is that the main run of applyChanges here makes two jobs:
|
|
the first sets the flags for encryption/signing or not, and the other
|
|
starts the encryption process.
|
|
|
|
When a job is run, it has already been removed from the job queue. This
|
|
means if one of the current jobs needs to add new jobs, it can add them
|
|
to the front and that way control when new jobs are added.
|
|
|
|
For example, the compose message job will add jobs that will do the
|
|
actual encryption and signing.
|
|
|
|
There are two types of jobs: synchronous and asynchronous:
|
|
|
|
A synchronous job simply implments the execute() method and performs
|
|
it's operation there and sets mComposer->mRc to false if the compose
|
|
queue should be canceled.
|
|
|
|
An asynchronous job only sets up and starts it's operation. Before
|
|
returning, it connects to the result signals of the operation
|
|
(e.g. Kleo::Job's result(...) signal) and sets mComposer->mHoldJobs
|
|
to true. This makes the scheduler return to the event loop. The job
|
|
is now responsible for giving control back to the scheduler by
|
|
calling mComposer->doNextJob().
|
|
*/
|
|
|
|
/*
|
|
Test plan:
|
|
|
|
For each message format (e.g. openPGP/MIME)
|
|
1. Body signed
|
|
2. Body encrypted
|
|
3. Body signed and encrypted
|
|
4. Body encrypted, attachments encrypted (they must be encrypted together, mEarlyAddAttachments)
|
|
5. Body encrypted, attachments not encrypted
|
|
6. Body encrypted, attachment encrypted and signed (separately)
|
|
7. Body not encrypted, one attachment encrypted+signed, one attachment encrypted only, one attachment signed only
|
|
(https://intevation.de/roundup/aegypten/issue295)
|
|
(this is the reason attachments can't be encrypted together)
|
|
8. Body and attachments encrypted+signed (they must be encrypted+signed together, mEarlyAddAttachments)
|
|
9. Body encrypted+signed, attachments encrypted
|
|
10. Body encrypted+signed, one attachment signed, one attachment not encrypted nor signed
|
|
...
|
|
|
|
I recorded a KDExecutor script sending all of the above (David)
|
|
|
|
Further tests (which test opportunistic encryption):
|
|
1. Send a message to a person with valid key but without encryption preference
|
|
and answer the question whether the message should be encrypted with Yes.
|
|
2. Send a message to a person with valid key but without encryption preference
|
|
and answer the question whether the message should be encrypted with No.
|
|
3. Send a message to a person with valid key and with encryption preference
|
|
"Encrypt whenever possible" (aka opportunistic encryption).
