Installation:

	cd bien/

	Install: make install

	**WARNING**: system upgrades can break key parts of the full-database

		import, causing errors such as disk space overruns. for this reason, it

		is recommended to maintain a snapshot copy of the VM as it was at the

		last successful import, for fallback use if a system upgrade breaks

		anything. system upgrades on the snapshot VM should be disabled

		completely, and because this will also disable security fixes, the

		snapshot VM should be disconnected from the internet and all networking

		interfaces. (this is an unfortunate consequence of modern OSes being

		written in non-memory-safe languages such as C and C++.)

	**WARNING**: always start with a clean shell, to avoid spurious bugs. the

		shell should not have changes to the env vars. (there have been bugs

		that went away after closing and reopening the terminal window.) note

		that running `exec bash` is not sufficient to *reset* the env vars.

	**WARNING**: shell scripts should always be read-only, so that editing them

		while an import is in progress will not crash the import (see

		http://vegpath.org/links/#**%20modifying%20a%20running%20shell%20script)

	Update the auxiliary schemas: make schemas/reinstall

	Delete imports before the last so they won't bloat the full DB backup:

		make backups/vegbien.<version>.backup/remove

		To keep a previous import other than the public schema:

			export dump_opts='--exclude-schema=public --exclude-schema=<version>'

		import (this is apparently not automatically reclaimed):

		make postgres_restart

		**WARNING**: sometimes, this amount of available space is insufficient

			and the entire disk space gets used up, crashing the import. if this

			occurs, the problem will often be fixed just by rerunning the import

			again. (the high-water mark varies by import.)

		although the import schema itself is only 315 GB, Postgres uses

			for the first day (for import started @12:55:09, high-water marks of

		unset log # allow logging output to go to log files

	if no commits have been made since the last import (eg. if retrying an

			# download backup to local machine

		For each newly-archived backup:

			make -s <backup>.md5/test

			Check that "OK" is printed next to the filename

	If desired, record the import times in inputs/import.stats.xls:

		If the rightmost import is within 5 columns of column IV:

			Copy the current tab to <leftmost-date>~<rightmost-date>

			Remove the previous imports from the current tab because they are

				now in the copied tab instead

		Insert a copy of the leftmost "By column" column group before it

		export version=<version>

		bin/import_date inputs/{.,}*/*/logs/$version.log.sql

		Update the import date in the upper-right corner

		bin/import_times inputs/{.,}*/*/logs/$version.log.sql

		Paste the output over the # Rows/Time columns, making sure that the

			row counts match up with the previous import's row counts

		If the row counts do not match up, insert or reorder rows as needed

			until they do. Get the datasource names from the log file footers:

			tail inputs/{.,}*/*/logs/$version.log.sql

			make inputs/.TNRS/reinstall

			re-create public-schema views that were cascadingly deleted

			tail -100 inputs/.TNRS/tnrs/logs/tnrs.make.log.sql

			$version with the appropriate revision

		<datasrc> may not contain spaces, and should be abbreviated.

		If the datasource is a herbarium, <datasrc> should be the herbarium code

			as defined by the Index Herbariorum <http://sweetgum.nybg.org/ih/>

		For .sql exports:

			Place the original .sql file in _src/ (*not* in _MySQL/)

			Follow the steps starting with Install the staging tables below.

				This is for an initial sync to get the file onto vegbiendev.

					UPDATE, DELETE, ALTER, DROP. This prevents bugs in the

					import scripts from accidentally deleting data.

		mkdir inputs/<datasrc>/_MySQL/

		cp -p lib/MySQL.{data,schema}.sql.make inputs/<datasrc>/_MySQL/

		Edit _MySQL/*.make for the DB connection

			For a .sql export, use server=vegbiendev and --user=bien

		Skip the Add input data for each table section

	For MS Access databases:

		Place the .mdb or .accdb file in _src/

		Download and install Access To PostgreSQL from

			http://www.bullzip.com/download.php

		Use Access To PostgreSQL to export the database:

			Export just the tables/indexes to inputs/<datasrc>/<file>.schema.sql

			Export just the data to inputs/<datasrc>/<file>.data.sql

		In <file>.schema.sql, make the following changes:

			Replace text "BOOLEAN" with "/*BOOLEAN*/INTEGER"

			Replace text "DOUBLE PRECISION NULL" with "DOUBLE PRECISION"

		Skip the Add input data for each table section

	Add input data for each table present in the datasource:

		For .sql exports, you must use the name of the table in the DB export

		For CSV files, you can use any name. It's recommended to use a table

			name from <https://projects.nceas.ucsb.edu/nceas/projects/bien/wiki/VegCSV#Suggested-table-names>

		Note that if this table will be joined together with another table, its

			name must end in ".src"

		make inputs/<datasrc>/<table>/add

			Important: DO NOT just create an empty directory named <table>!

				This command also creates necessary subdirs, such as logs/.

		If the table is in a .sql export: make inputs/<datasrc>/<table>/install

			Otherwise, place the CSV(s) for the table in

			inputs/<datasrc>/<table>/ OR place a query joining other tables

			together in inputs/<datasrc>/<table>/create.sql

		Important: When exporting relational databases to CSVs, you MUST ensure

			that embedded quotes are escaped by doubling them, *not* by

			preceding them with a "\" as is the default in phpMyAdmin

		If there are multiple part files for a table, and the header is repeated

			in each part, make sure each header is EXACTLY the same.

			assumes the part files don't have individual headers and treats the

			subsequent headers as data rows.)

			that depend on it

			"cp" -f inputs/.NCBI/nodes/run inputs/<datasrc>/<table>/

			inputs/<datasrc>/<table>/run

		make inputs/<datasrc>/reinstall quiet=1 &

		For a MySQL .sql export:

			At prompt "[you]@vegbiendev's password:", enter your password

			At prompt "Enter password:", enter the value in config/bien_password

		To view progress: tail -f inputs/<datasrc>/<table>/logs/install.log.sql

		View the logs: tail -n +1 inputs/<datasrc>/*/logs/install.log.sql

			tail provides a header line with the filename

			+1 starts at the first line, to show the whole file

		For every file with an error 'column "..." specified more than once':

			Add a header override file "+header.<ext>" in <table>/:

				Note: The leading "+" should sort it before the flat files.

					"_" unfortunately sorts *after* capital letters in ASCII.

				Create a text file containing the header line of the flat files

				Add an ! at the beginning of the line

					This signals cat_csv that this is a header override.

				For empty names, use their 0-based column # (by convention)

				For duplicate names, add a distinguishing suffix

				For long names that collided, rename them to <= 63 chars long

				Do NOT make readability changes in this step; that is what the

					map spreadsheets (below) are for.

				Save

		If you made any changes, re-run the install command above

	Auto-create the map spreadsheets: make inputs/<datasrc>/

	Map each table's columns:

		In each <table>/ subdir, for each "via map" map.csv:

			Open the map in a spreadsheet editor

			Open the "core map" /mappings/Veg+-VegBIEN.csv

			In each row of the via map, set the right column to a value from the

				left column of the core map

			Save

		Regenerate the derived maps: make inputs/<datasrc>/

	Accept the test cases:

			inputs/<datasrc>/run

			svn di inputs/<datasrc>/*/test.xml.ref

			If you get errors, follow the steps for old-style datasources below

		For an old-style datasource:

			make inputs/<datasrc>/test

			If you instead get errors, do one of the following for each one:

			-	If the error was due to a bug, fix it

			-	Add a SQL function that filters or transforms the invalid data

			-	Make an empty mapping for the columns that produced the error.

				Put something in the Comments column of the map spreadsheet to

				prevent the automatic mapper from auto-removing the mapping.

			When accepting tests, it's helpful to use WinMerge

				(see WinMerge setup below for configuration)

		make inputs/<datasrc>/test by_col=1

			If you get errors this time, this always indicates a bug, usually in

				the VegBIEN unique constraints or column-based import itself

	Add newly-created files: make inputs/<datasrc>/add

	Commit: svn ci -m "Added inputs/<datasrc>/" inputs/<datasrc>/

	Update vegbiendev:

			./fix_perms

			make inputs/upload

	on a live machine, you should put the following in your .profile:

--

# make svn files web-accessible. this does not affect unversioned files, because

# these get the right permissions on the local machine instead.

umask ug=rwx,o=rx

unset TMOUT # TMOUT causes screen to exit even with background processes

--

		Linux and Mac OS X.

Backups:

	Archived imports:

			Note: To back up the last import, you must archive it first:

				make schemas/rotate

		Test: make -s backups/<version>.backup/test &

		Restore: make backups/<version>.backup/restore &

		Remove: make backups/<version>.backup/remove

		Download: make backups/<version>.backup/download

	TNRS cache:

			runtime: 3 min ("real 2m48.859s")

		Restore:

			yes|make inputs/.TNRS/uninstall

			make backups/TNRS.backup/restore &

				runtime: 5.5 min ("real 5m35.829s")

			yes|make schemas/public/reinstall

				Must come after TNRS restore to recreate tnrs_input_name view

	Full DB:

		Test: make -s backups/vegbien.<version>.backup/test &

		Restore: make backups/vegbien.<version>.backup/restore &

		Download: make backups/vegbien.<version>.backup/download

	Import logs:

		make inputs/VegBank/reinstall quiet=1 &

		to update the corresponding table

	Remember to update the following files with any renamings:

		schemas/filter_ERD.csv

		mappings/VegCore-VegBIEN.csv

		mappings/verify.*.sql

	Regenerate schema from installed DB: make schemas/remake

	Reinstall DB from schema: make schemas/public/reinstall schemas/reinstall

			Fix any bugs and retry until no errors

				This must be run *after* the datasources are installed, because

				views in public depend on some of the datasources

			on the local machine, or the live DB may be unrestorable!

	Refactoring tips:

		To rename a table:

			In vegbien.sql, do the following:

				Replace regexp (?<=_|\b)<old>(?=_|\b) with <new>

					This is necessary because the table name is *everywhere*

				Search for <new>

				Manually change back any replacements inside comments

		To rename a column:

			Rename the column: ALTER TABLE <table> RENAME <old> TO <new>;

			Recreate any foreign key for the column, removing CONSTRAINT <name>

				This resets the foreign key name using the new column name

	Creating a poster of the ERD:

		Determine the poster size:

			Measure the line height (from the bottom of one line to the bottom

				of another): 16.3cm/24 lines = 0.679cm

			Measure the height of the ERD: 35.4cm*2 = 70.8cm

			Zoom in as far as possible

			Measure the height of a capital letter: 3.5mm

			Measure the line height: 8.5mm

			Calculate the text's fraction of the line height: 3.5mm/8.5mm = 0.41

			Calculate the text height: 0.679cm*0.41 = 0.28cm

			Calculate the text height's fraction of the ERD height:

				0.28cm/70.8cm = 0.0040

			Measure the text height on the *VegBank* ERD poster: 5.5mm = 0.55cm

			Calculate the VegBIEN poster height to make the text the same size:

				0.55cm/0.0040 = 137.5cm H; *1in/2.54cm = 54.1in H

			The ERD aspect ratio is 11 in W x (2*8.5in H) = 11x17 portrait

			Calculate the VegBIEN poster width: 54.1in H*11W/17H = 35.0in W

			The minimum VegBIEN poster size is 35x54in portrait

		Determine the cost:

			The FedEx Kinkos near NCEAS (1030 State St, Santa Barbara, CA 93101)

				charges the following for posters:

				base: $7.25/sq ft

				lamination: $3/sq ft

				mounting on a board: $8/sq ft

		Including column-based import: make test by_col=1

			If the row-based and column-based imports produce different inserted

			row counts, this usually means that a table is underconstrained

			(the unique indexes don't cover all possible rows).

			This can occur if you didn't use COALESCE(field, null_value) around

			a nullable field in a unique index. See sql_gen.null_sentinels for

			the appropriate null value to use.
