2015-07-27[bug] avoid double decryption of documentsdrebs
Because of how the incoming document queue is implemented, it could be the case that a document was sent to async decryption queue more than once. This commit creates a list of documents to be decrypted, so we avoid sending the same document to the queue more than once.
2015-07-27[bug] fix order of incoming document eventsdrebs
The incoming documents events are meant to be used by a progress bar for soledad sync, yet to be implemented. When deferred decryption was used, the events were sent out of order, depending on the order of arrival of the documents. This commit changes it so that the content of the emited events are in order, so it is meaningful for the implementation of a progress bar. Note that even after documents are received from the server, they will still be decrypted asynchronously, so another signal could be implemented to signal for the waiting of the decryption of incoming documents.
2015-07-27[bug] remove mac from secrets filedrebs
This is how a secret was stored in the secrets json file: * each secret is symmetrically encrypted amd MACed with keys derived from the user's passphrase. * the encrypted secrets dictionary is then MACed with another key derived * from the user's passphrase. * each key is derived using scrypt and a unique random salt. There are disadvantages to this approach: * repeating scrypt many times is a waste of time. * an attacker could crack whichever has weaker parameters, if they get out of sync. * if an attacker can modify the secret in a way it is good to decrypt the database, then she can also modify the MAC. The solution for this is: * completelly eliminate the MAC from the storage secrets file. * attempt to decrypt the database with whatever is got from the decryption of the secret. If that is wrong, report an error. Closes #6980.
2015-07-22[refactor] use a deferred to signal when SyncDecriptionPool has finishedRuben Pollan
It makes the code simpler and clearer to use a deferred instead of having to pull on 'has_finished'. - Related: #7234

2015-06-03[bug] do not block when getting doc for async encdrebs
Previous to this change, the actual encryption method used to run on its own thread. When the close method was called from another thread, the queue could be deleted after the encryption method loop had started, but before the queue was checked for new items. By removing that thread and moving the encryption loop to the reactor, that race condition should disappear. Closes: #7088.

2015-05-25[feature] add pool of http/https connectionsdrebs
Instead of opening one TCP connection for each HTTP request, we want to reuse connections. Also, we need to be able to verify SSL certificates. This commit implements both features in the twisted http client sync.
2015-05-20[feature] use twisted.web.client in client syncdrebs
This change uses twisted deferreds for the whole syncing process and paves the way to implementing other transport schemes. It removes a lot of threaded code that used locks and was very difficult to maintain, and lets twisted to the dirty work. Furthermore, all blocking network i/o is now handled asynchronously by the twisted. This commit removes the possibility of interrupting a sync, and we should reimplement it using cancellable deferreds if we need it.
2015-05-20[bug] fix order of insertion of decrypted docsdrebs
This commit actually does some different things: * When doing asynchronous decryption of incoming documents in soledad client during a sync, there was the possibility that a document corresponding to a newer generation would be decrypted and inserted in the local database before a document corresponding to an older generation. When this happened, the metadata about the target database (i.e. its locally-known generation) would be first updated to the newer generation, and then an attempt to insert a document corresponding to an older generation would cause the infamous InvalidGeneration error. To fix that we use the sync-index information that is contained in the sync stream to correctly find the insertable docs to be inserted in the local database, thus avoiding the problem described above. * Refactor the sync encrypt/decrypt pool to its own file. * Fix the use of twisted adbapi with multiprocessing. Closes: #6757.
2015-05-20[feature] use async adbapi for async decryptiondrebs
Since we started implementing twisted api in soledad, some pieces are missing. Accessing the sqlcipher database directly with the twisted adbapi facilities is one of them. The async encryption/decryption was touching the database directly, and this was causing some difficulties like having different threads accessing the same database. This commit implements the twisted adbapi stuff for the asynchronous encryption/decryption facilities. Next steps would be use async adbapi for async encryption and use async adbapi for all sqlcipher access.
2015-05-20[bug] fix log messages for secrets in storagedrebs
2015-05-20[bug] fix log messages when fetching documentsdrebs
We always got a log message saying "canceling sync threads" in the end of the sync process, even when there was no error during the sync. This commit changes that in a way that we only have that log when the sync was actually cancelled because of an error.
2015-05-20[bug] always initialize sync dbdrebs
Both deferred encryption and decryption rely on a special sync db. Previous to this fix, the sync db was only initialized if a syncer was configured with deferred encryption capabilities. This was a problem when the syncer was not configured like so, but the actual sync method was initiated configured to do deferred decryption. This commit fixes this by always initializing the sync db, so we have the option of doing all combinations of deferred encryption and decryption.

Add dependency on twisted for Soledad Client. Also remove minimum twisted version for Soledad Server because debian stable currently distributes 12.0.0 and pypi currently distributes 15.0.0. Closes: #6797
