2016-08-22[test] test soledad instatiation timeVictor Shyba
It has a heavy scrypt hashing processing with room for improvement.
2016-08-22[test] sync without changesVictor Shyba
Syncing without any changes was reported as slow. This benchmark will help measure it.
2016-08-22[test] remove fixed default uuidVictor Shyba
Use a new one to avoid reusing the same database.
2016-08-22[test] make all nested fixture function-scopedVictor Shyba
function is the default scope, so there is no need to pass this parameter. Previously, one of the scopes was 'module', but it is a nested function that fires on demand, so it should clean up itself from test to test in order to avoid conflict while putting.
2016-08-22[test] adds sqlcipher synchronous testsVictor Shyba
2016-08-22[test] adds sqlcipher create testsVictor Shyba
Creating 20/500k, 100/100k and 1000/10k.
2016-08-22[test] use a nested func to simplify scenariosVictor Shyba
If we have many scenarios (like 20/500k, 100/100k, 1000,10k) then making a nested function to generate tests based on scenario parameters simplifies the code a lot.
2016-08-22[test] Adds pytest-benchmark adapted to TwistedVictor Shyba
Adapted pytest-benchmark to Twisted as it's synchronous and added fixtures for benchmarking.
2016-08-17[tests] Adapt tests for ensure_ddocs deathVictor Shyba
2016-08-17[bug] remove misleading ensure_ddocVictor Shyba
ensure_ddoc doesnt make sense anymore as we dont have any ddoc other than _security, which has its own method for setting. 'ensure_security' is explicit and is set internally when user is creating a database, otherwise it will be False as it's only used during creation. This isn't exposed externally (of couch module) to avoid confusion. This confusion was making create-user-db fail to create a security ddoc as it wasn't passing ensure_ddocs=True. -- Resolves: #8388
2016-08-15[test] allow for shell autocomplete for test namesdrebs
tox was configured to change to the testing/tests directory before executing pytest, by using tox's "changedir" configuration option. The reason why this was the case is that we wanted to discover tests inside the testing/tests directory only. The problem with that approach is that if we wanted to point to a specific test file, for example "tests/perf/test_sync.py", we would have to omit the "tests" part and write "tox perf/test_sync.py" because the argument would be understood as relative to the changed dir. That is not practical as doesn't allow to use the shell autocomplete, and is also not the only way to achieve what we want. Actually, pytest has a configuration option called "testpaths" where you can indicate where it should discover tests. This commit changes one approach by the other and allows to user shell autocomplete for easyness of testing during development.

2016-08-08[pkg] remove version pinning for couchdb and beakerdrebs
We will not maintain support for older versions of debian as that introduces some unneeded complexity for now. Also, the version pinned for couchdb python library has a bug that makes some requests slow. Because of those, we remove the pinning for now.
2016-08-05[bug] create gen document after saving the actual document in couchdrebs
If we create the gen document before saving the actual document in couch, we may run into problems if more than one client is syncing and trying to save documents with the same id at the same time. By moving the gen document creation to after the actual document save in couch, we rely on couch/u1db resolution of conflicts before actually allocating a new generation, and the problem above doesn't occur.

2016-08-02[test] avoid race condition on test_processing_orderVictor Shyba
test_processing_order aims to check that unordered docs wont be processed, but if we let the pool start and advance Twisted LoopingCall clock right before calling the processing method manually, the process method will run concurrently and cause a race condition issue.

2016-08-01[bug] retry allocation of gen instead of using a lockdrebs
The use of a lock to allocate the next generation of a change in couch backend suffers from at least 2 problems: 1. all modification to the couch database would have to be made through a soledad server entrypoint, otherwise the lock would have no effect. 2. introducing a lock makes code uglier, harder to debug, and prone to undesired blocks. The solution implemented by this commit is not so elegant, but works for what we need right now. Now, concurrent threads updating the couch database will race for the allocation of a new generation, and retry when they fail to do so. There's no high risk of getting blocked for too much time in the while loop because (1) there's always one thread that wins (what makes the expected number of retries to be N/2 if N is the number of concurrent threads), and (2) the number of concurrent attempts to update the user database is limited by the number of devices syncing at the same time.
2016-08-01[feat] use couch _all_docs for get_docs() and get_all_docs()drebs
The previous solution would make use of concurrent get's to couch backend in a pool of threads to implement the get_docs() and get_all_docs() CouchDatabase backend methods. This commit replaces those by a simpler implementation use the `_all_docs` couchdb view api. It passes all needed IDs to the view and r etrieves all documents with content in the same request. A comparison between both implementations shows an improvement of at least 15 times for large number of documents. The table below shows the time for different implementations of get_all_docs() for different number of documents and threads versus _all_docs implementation: +-------+-----------------+------------------+-------------+ | | threads | _all_docs | improvement | +-------+-----------------+------------------+-------------+ | 10 | 0.0728030204773 | 0.00782012939453 | 9.3 | | 100 | 0.609349966049 | 0.0377721786499 | 16.1 | | 1000 | 5.86522197723 | 0.370730876923 | 15.8 | | 10000 | 66.1713931561 | 3.61764383316 | 18.3 | +-------+-----------------+------------------+-------------+

`pytest_addoption` was declared twice making the second declaration replace the first, thus removing couch url parameter.

2016-08-01[test] avoid perf tests to be run on normal tox callsdrebs
Currently the perf tests use pytest-twisted plugin, and this has some implications in the old tests adapted from u1db that now use trial classes. Because of that, we exclude perf tests from usual tox calls, but you can still run them by explicitelly calling `tox perf`.

2016-08-01[bug] fix order of multipart serialization when writing to couchdrebs
The couch backend makes use of attachments and multipart structure for writing the document to the couch database. For that to work, the order in which attachments are described must match the actual order in which attachments are written to the couch http stream. This was not being properly taken care of, and eventually the json serializer was arbitrarilly ordering the attachments description in a way that it didn't match the actual order of attachments writing. This commit fixes that by using json.dumps() sort_keys parameter and making sure conflicts are always written before content.
2016-08-01[test] remove traces of design docs from couch testsdrebs
2016-08-01[feat] remove usage of design documents in couchdrebs
Design documents are slow and we already have alternatives to all uses we used to make of them, so this commit completelly removes all usage of design documents.
2016-07-25[test] adapt couch tests to use new generation/transaction storage schemedrebs
2016-07-25[feat] do not use couch views for sync metadatadrebs
When compared to plain couch document get, the use of the simplest view functions takes around double the time, while the use of the simplest list function can take more than 8 times: get 100 docs: total: 0.440337 secs mean: 0.004403 query 100 views: total: 0.911425 secs mean: 0.009114 query 100 lists: total: 3.711537 secs mean: 0.037115 Besides that, the current implementation of sync metadata storage over couch is dependent of timestamps of document puts, what can lead to metadata corruption if the clock of the system is changed for any reason. Because of these reasons, we seek to change the implementation of database metadata. This commit implements the storage of transaction log data on couch documents with special ids, in the form "gen-xxxxxxxxxx", where the x's are replaced by the generation index. Each generation document holds a dictionary containing the generation, doc_id and transaction_id for the changed document. For each modified document, a generation document is inserted holding the transaction metadata.
