* fdl: fix "used before set" warnings in libreconJeff Darcy2016-04-011-1/+23
| | | | | | | | | | | | Newer compilers were complaining about this in generated code, because cleanup code fragments were being added in the wrong order.

* fdl: fix race during initializationJeff Darcy2016-03-101-7/+7
| | | | | | | | | | | | | | | | | | | | | | There was a race between fdl_worker starting to run and setting this->private in fdl_init. This should never happen on a multiprocessor, since the new thread should start on a different core and creating it there should take many times longer than getting from pthread_create to the end of fdl_init on the original core. The only way it seems likely is if the new thread is started on the same core that's already in fdl_init, and the new thread preempts the old, which many would consider broken . . . but there are plenty of broken thread implementations and it's hardly surprising that glibc has one. Still, it's a race and it did show up in regression tests a few times, so it needs to be fixed.

* experimental: add fdl (Full Data Logging) translatorJeff Darcy2016-02-1310-0/+1797
NSR needs logging that is different than our existing changelog in several ways: * Full data, not just metadata * Pre-op, not post-op * High performance * Supports the concept of time-bounded "terms" Others (for example EC) might need the same thing. This patch adds such a translator. It also adds code to dump the resulting journals, and to replay them using syncops, plus (very rudimentary) tests for all of the above.
