Installation:

    Install: make install

        WARNING: This will delete the current public schema of your VegBIEN DB!

    Uninstall: make uninstall

        WARNING: This will delete your entire VegBIEN DB!

        This includes all archived imports and staging tables.

Maintenance:

    Important: Whenever you install a system update that affects PostgreSQL or

        any of its dependencies, such as libc, you should restart the PostgreSQL

        server. Otherwise, you may get strange errors like "the database system

        is in recovery mode" which go away upon reimport.

Data import:

    On local machine:

        make test by_col=1

            See note under Testing below

    On vegbiendev:

    svn up

    make inputs/upload

    For each newly-uploaded datasource: make inputs/<datasrc>/reinstall

    Update the schemas: make schemas/reinstall

        WARNING: This will delete the current public schema of your VegBIEN DB!

        To save it: make schemas/rotate

        Important: This must be done *after* running make_analytical_db on a

            previous import

    Start column-based import: . bin/import_all by_col=1

        To use row-based import: . bin/import_all

        To stop all running imports: . bin/stop_imports

        WARNING: Do NOT run import_all in the background, or the jobs it creates

            won't be owned by your shell.

        Note that import_all will several hours to import the NCBI backbone and

            TNRS names before returning control to the shell.

    Wait (overnight) for the import to finish

    tail inputs/{.,}*/*/logs/*.r<revision>[.-]*log.sql

    Check that every input's log ends in "Encountered 0 error(s)"

    If many do not, fix the bug and discard the current (partial) import:

        make schemas/public/reinstall

    Otherwise, continue

    Determine the import name:

        bin/import_name inputs/{.,}*/*/logs/*.r<revision>[.-]*log.sql

    Archive the last import: make schemas/rename/public.<import_name>

        Important: This must be done *after* running make_analytical_db

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

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

    make backups/TNRS.backup-remake &

    make backups/public.<version>.backup/test &

    make backups/vegbien.<version>.backup/test &

    On local machine:

        make inputs/download-logs

        make backups/download

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

        Open inputs/import.stats.xls

        Insert a copy of the leftmost Column-based column group before it

        Update the import date in the upper-right corner

        ./bin/import_times inputs/{.,}*/*/logs/*.r<revision>[.-]*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

        Commit: svn ci -m "inputs/import.stats.xls: Updated import times"

    To remake analytical DB: bin/make_analytical_db &

        To view progress:

            tail -f inputs/analytical_db/logs/make_analytical_db.log.sql

Backups:

    Archived imports:

        Back up: make backups/public.<date>.backup &

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

        Test: make backups/public.<date>.backup/test &

        Restore: make backups/public.<date>.backup/restore &

        Remove: make backups/public.<date>.backup/remove

        Download: make backups/download

    Import logs:

        Download: make inputs/download-logs

Datasource setup:

    Add a new datasource: make inputs/<datasrc>/add

        <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/>

    Install any MySQL export:

        Create database in phpMyAdmin

        mysql -p database <export.sql

    Add input data for each table present in the datasource:

        Choose a table name from <https://projects.nceas.ucsb.edu/nceas/projects

            /bien/wiki/VegCSV#Suggested-table-names>, or use a custom name

        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/.

        Place the CSV 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.

             (If the headers are not the same, the CSV concatenation script

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

             subsequent headers as data rows.)

        Add <table> to inputs/<datasrc>/import_order.txt before other tables

            that depend on it

    Install the staging tables:

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

        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:

        make inputs/<datasrc>/test

            When prompted to "Accept new test output", enter y and press ENTER

            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

                either the 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:

        On vegbiendev: svn up

        On local machine: make inputs/upload

        On vegbiendev:

            Follow the steps under Install the staging tables above

            make inputs/<datasrc>/test

Schema changes:

    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/reinstall

    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:

        Measure the fractional height of the text onscreen:

            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

Testing:

    Mapping process: make test

        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.
