2015-05-20[bug] remove unused pending documents exceptiondrebs
When we started implementing the sync db, one of the ideas was to reuse the data in the database in the case of a sync interruption. We don't do that now and thus the pending documents exception is unneeded. This commit removes that exception from the code.
2015-05-20[bug] remove illegal CR from auth headerKali Kaneko
The b64 encoding of the auth token was introducing an illegal character (\n), which was breaking the authentication step since an exception was being raised - when that multi-line header was attempted to be built. this commit fixes that bug. - Resolves: #6959
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 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.

2015-04-28[bug] remove old code for sync deferred db initdrebs
The database initialization on the client sync module is deferred to another thread. As there is only one thread in the thread pool, this should not be a problem for now, as operations will actually be queued in that thread. There was some old code left from when we had to explicitelly wait for the db to be initialize before using it. This commit removes that old code and introduces some documentation so we remember to deal with deferred db init if we ever change the number of threads in the thread pool.

2015-04-28[bug] log traceback on sync failures on clientdrebs
Conversion of Twisted failures to string that rely on __str__ or __repr__ might not return all the information we would like to have, especially on sync failures. This commit asks for a detailed traceback of such failures and logs them both in Twisted and client logs.
2015-04-23[feat] ensure sync fails will raise an exceptiondrebs
This commit makes 2 changes that allow sync failures to raise exceptions that can be caught by the api: 1. Remove try/except statements in sync.py level that would prevent an exception to be caught by the soledad client api. 2. Ensure that if an asynchronous decrypting process fails the exception will be re-raised to eventually reach the api. Related: #6757.
2015-04-23[bug] fail gracefully when sync failsdrebs
With new soledad async api, we need to catch errors using errbacks instead of catching exceptions explicitelly. This commit fixed the api sync() call to intercept sync failures, log them, and do not propagate them down the callback chain.
2015-03-19[fix] add explicit dependency on leap.commondrebs
In the past, we wanted dependency on leap.common to be optional, but now because of the explicit use of the config path prefix and signaling, we want to enforce dependency on leap.common.

Right now we're reusing the connection from multiple threads in the syncer. I'm assuming the writes are automatically locking the file at the sqlite level, so this shouldn't pose a problem. [ ] Correctly handle the multiprocessing pool, and the callback execution.

2014-12-09Fix incorrect ssl context setupKali Kaneko
The changes introduced in aafa79c0f5 having to do with the cert verification are incorrect, regarding the use of the newest ssl context api introduced in python 2.7.9. There the use of the server setup was taken, instead of the correct client options. I hereby apologize for the insuficient testing on that fix. It happens that I wrongly tested in an evironment that did the fallback to pre-2.7.9 interpreter.

Although the API can be misleading, PROTOCOL_SSLv23 selects the highest protocol version that both the client and server support. Despite the name, this option can select “TLS” protocols as well as “SSL”. In this way, we can use TLSv1.2 (PROTOCOL_TLSv1 will *only* give us TLS v1.0) In the client side, we try to disable SSLv2 and SSLv3 options explicitely. The python version in wheezy does not offer PROTOCOL_TLSv1_2 nor OP_NO_SSLv2 or OP_NO_SSLv3 (It's new in 2.7.9)
