* cache ctx in collection handle * cache rd together with rda * do not repeatedy call rrdcontexts - cached collection status; optimize pluginsd_acquire_dimension() * fix unit tests * do the absolutely minimum while updating timestamps, ensure validity during reading them * when the stream is INTERPOLATED, buffer outstanding data for up to 50ms if the buffer contains DATA only. * remove the spinlock from mrg * remove the metric flags that are not used any more * mrg writers can be different threads * update first time when latest clean is also updated * cleanup * set hot page with a simple atomic operation * sender sets chart slot for every chart * work on senders without SLOT * enable SLOT capability * send slot at BEGIN when SLOT is enabled * fix slot generation and parsing * send slot while re-streaming * use the sender capabilities, not the receiver * cleanup * add slots support to all chart and dimension related plugin commands * fix condition * fix calculation * check sender capabilties * assign slots in constructors * we need the dimension slot at the DIMENSION keyword * more debug info in case of dimension mismatch * ensure the RRDDIM EXPOSED flag is multi-threaded and set it after the sender buffer has been committed, so that replication will not send dimensions prematurely * fix renumbering on child restart * reset rda caching when receiving a chart definition * optimize pluginsd_end_v2() * do not do zero sized allocations * trust the chart slot id of the child * cleanup charts on pluginsd thread exit * better cleanup * find the chart and put it in the slot, if it not already there * move slots array to host * initialize pluginsd slots properly * add slots to replay begin; do not cleanup slots that dont belong to a chart * cleanup on obsolete * cleanup slots on obsoletions * cleanup and renames about obsoletion * rewrite obsolation service code to remove race conditions * better service obsoletion log * added debugging * more debug * exposed flag now compares versions * removed debugging messages * respolve conflicts * fix replication check for unsent dimensions
