Dataweb: Generate IBEX pages

[KathrynBaker]

A web service needs to pull in the various pages of blocks and run information from the instrument, as well as the config details, and build an appropriate page showing the current values

This should be possible in any language available, but given the use of JSON and XML, and that the majority of the work is string manipulation, this would be best developed as server side javascript.

The page:

• needs to display certain items of run information (specified rows from the INST page)
• needs to display the blocks by group (information in the current config details)
• needs to differentiate between visible blocks (from the BLOCKS page) and hidden blocks (from the DATAWEB page)
• needs to default to displaying only visible blocks, only showing hidden ones when that option is selected
• needs to pay attention to the "hide title" PV (from the INST page), and hide the title, RB Number and Usernames when the PV is set to hidden
• if the current config details are unavailable it should display an appropriate message, e.g. "INST is offline, the last config in use was xxxxxx at yyyyyyy"
• if it receives a 400 error from the archive engine servers it should send a restart command to that server, if after that restart the server is still unavailable it should display an appropriate message, e.g. "INST is offline, the last config in use was xxxxxx at yyyyyyy"
• if there are blocks or run information expected, which can't be found in the information from the archive engine it should send a restart command to that server, if after that restart the information is still unavailable the appropriate field should be listed as "Unreachable"
• if the block or run information is disconnected, the value for that block should be listed as "Disconnected"
• the value for the block or run information should be parsed from the current value field, removing time stamps and alarm statuses at this point

The URL for the current config will be the one created in #1380 The name host has been used in the references below, this will work with localhost on a local machine, but it will need to specify an IBEX instrument name in the final service. To reset the archive engine for the blocks: http://host:4813/reset To reset the archive engine for the run infomration: http://host:4812/reset The INST page is: http://host:4812/group?name=INST The BLOCKS page is: http://host:4813/group?name=BLOCKS The DATAWEB page is: http://host:4813/group?name=DATAWEB The details for the hidden PV should be available from #1373

The run information is as follows:

RUNSTATE	$(P)DAE:RUNSTATE_STR	Run Status
RUNNUMBER	$(P)DAE:RUNNUMBER	Run Number
RBNUMBER	$(P)DAE:_RBNUMBER	RB Number

An example page with a hidden title and only showing visible blocks is:

With hidden blocks visible: http://dataweb.isis.rl.ac.uk/SeciWeb/Advanced.aspx?Instrument=nimrod

Notes: The configuration name will need to come from the current configuration The shutter status is not currently available to the dataweb The run information could be treated as a specific group, and displayed in one column on the left hand of the page, the blocks title could be treated as an empty group and displayed at the top of the right column, to be followed by the groups and their associated blocks

Hidden blocks will be put into a separate ticket.

I'll include the ticket #1511 PR for genie_python in this Ticket as it's needed to launch the web server:

https://github.com/ISISComputingGroup/genie_python/pull/45

[AdrianPotter]

I've done a preliminary review, but the code threw an exception on the first GET request to the web server. I'd like to see that fixed please before getting further into the review.
