Convert mh2sql to the new history confguration scheme
Make empty connect string to hs_connect() mean use sqlite database in current directory. Also remove some debug output.
Enable reading of history last_written
Simplify time computations in generate_hist_graph()
Merge branch 'develop' into feature/history
Implement start_time for SQLITE history hs_get_last_written()
No changes. Reindent and repair broken lines in generate_hist_graph()
generate_hist_graph() plot run markers from data colleted by read_history() and remove the extra call to hs_read(). Now all plot data is collected from one hs_read(), plus an hs_get_last_written(), if needed.
Fix SL5 compiler warning in previous commit.
When looking at history plots, use absolute timestamps instead of time offsets relative to current time.
Implement history queries with hour granularity, remember previous query settings.
History "Query" now works for groups of plots and for "ALL" plots. Query time range is remembered across most history plot navigation and manipulaton. To switch back to the "Show last data" mode, use the "Reset" button or the ">>" button.
Fix small history plot breakage in plotting groups of plots and "ALL" plots.
Merge remote-tracking branch 'origin/develop' into feature/history
Merge remote-tracking branch 'origin/develop' into feature/history
Add history plot buttons "<<<" and "<<" to find the time when all plotted variables have data or at least one plotted variable has data.
Fix history buttons "<<<" and "<<" for plots with variables that have no data at all.
Removed obsolete register_cnaf_callback and added poll_event & interrupt_configure into _cplusplus section to be able to compile a frontend.cpp
Fix 32-bit and 64-bit compatibility problem with EQUIPMENT_INFO by adding a pad word. For reasons unknown some compilers seem to pad the structure size to 16 bytes. This breaks MIDAS db_open_record() & co.
Fix "make linux32" failure to build mlogger on 32-bit SL4
