    Important: Whenever you install a system update that affects PostgreSQL or
18
        any of its dependencies, such as libc, you should restart the PostgreSQL
19
        server. Otherwise, you may get strange errors like "the database system
20 6820 aaronmk
        is in recovery mode" which go away upon reimport, or you may not be able
21 6821 aaronmk
        to access the database as the postgres superuser. This applies to both
22
        Linux and Mac OS X.

Data import:
25 4487 aaronmk
    On local machine:
26 7114 aaronmk
        make inputs/upload
27 4487 aaronmk
        make test by_col=1
28 5016 aaronmk
            See note under Testing below
29 4487 aaronmk
    On vegbiendev:
30 7032 aaronmk
    Ensure there are no local modifications: svn st
31 4482 aaronmk
    svn up
32 7114 aaronmk
    For each newly-uploaded datasource above: make inputs/<datasrc>/reinstall
33 6952 aaronmk
    Update the auxiliary schemas: make schemas/reinstall
34
        The public schema will be installed separately by the import process
35 6962 aaronmk
    Delete imports before the last so they won't bloat the full DB backup:
36
        make backups/vegbien.<version>.backup/remove
37 6802 aaronmk
    Make sure there is at least 100GB of disk space on /: df -h
38
        The import schema is 75GB, and may use additional space for temp tables
39 6804 aaronmk
        To free up space, remove backups that have been archived on jupiter:
40
            List backups/ to view older backups
41
            Check their MD5 sums using the steps under On jupiter below
42
            Remove these backups
43 6995 aaronmk
    unset version
44 5206 aaronmk
    Start column-based import: . bin/import_all by_col=1
45
        To use row-based import: . bin/import_all
46 4481 aaronmk
        To stop all running imports: . bin/stop_imports

        WARNING: Do NOT run import_all in the background, or the jobs it creates
48
            won't be owned by your shell.
49 6797 aaronmk
        Note that import_all will take several hours to import the NCBI backbone
50
            and TNRS names before returning control to the shell.
51 4481 aaronmk
    Wait (overnight) for the import to finish
52 6796 aaronmk
    On local machine: make inputs/download-logs
53 7030 aaronmk
    In PostgreSQL, check that the provider_count and source tables contain
54
        entries for all inputs
55 6964 aaronmk
    tail inputs/{.,}*/*/logs/$version.log.sql
56 6799 aaronmk
    In the output, search for "Command exited with non-zero status"
57
    For inputs that have this, fix the associated bug(s)
58
    If many inputs have errors, discard the current (partial) import:
59 6953 aaronmk
        make schemas/$version/uninstall
60 6103 aaronmk
    Otherwise, continue
61 6959 aaronmk

65 6888 aaronmk
        cd /data/dev/aaronmk/bien/backups
66 6719 aaronmk
        For each newly-archived backup:
67
            make <backup>.md5/test
68
            Check that "OK" is printed next to the filename

Datasource setup:
121 4219 aaronmk
    Add a new datasource: make inputs/<datasrc>/add
122
        <datasrc> may not contain spaces, and should be abbreviated.
123
        If the datasource is a herbarium, <datasrc> should be the herbarium code
124
            as defined by the Index Herbariorum <http://sweetgum.nybg.org/ih/>
125 6366 aaronmk
    For MySQL inputs (exports and live DB connections):
126
        For .sql exports:
127
            Place the original .sql file in _src/ (*not* in _MySQL/)
128
            Create a database for the MySQL export in phpMyAdmin
129
            mysql -p database <inputs/<datasrc>/_src/export.sql
130
        mkdir inputs/<datasrc>/_MySQL/
131
        cp -p lib/MySQL.{data,schema}.sql.make inputs/<datasrc>/_MySQL/
132
        Edit _MySQL/*.make for the DB connection
133
            For a .sql export, use your local MySQL DB
134 6372 aaronmk
        Install the export according to Install the staging tables below
135 4218 aaronmk
    Add input data for each table present in the datasource:
136 6365 aaronmk
        For .sql exports, you must use the name of the table in the DB export
137
        For CSV files, you can use any name. It's recommended to use a table
138
            name from <https://projects.nceas.ucsb.edu/nceas/projects/bien/wiki/VegCSV#Suggested-table-names>
139 4264 aaronmk
        Note that if this table will be joined together with another table, its
140
            name must end in ".src"
141 4219 aaronmk
        make inputs/<datasrc>/<table>/add
142 4342 aaronmk
            Important: DO NOT just create an empty directory named <table>!
143
                This command also creates necessary subdirs, such as logs/.
144 6373 aaronmk
        If the table is in a .sql export: make inputs/<datasrc>/<table>/install
145
            Otherwise, place the CSV(s) for the table in
146 6370 aaronmk
            inputs/<datasrc>/<table>/ OR place a query joining other tables
147
            together in inputs/<datasrc>/<table>/create.sql
148 4212 aaronmk
        Important: When exporting relational databases to CSVs, you MUST ensure
149
            that embedded quotes are escaped by doubling them, *not* by
150
            preceding them with a "\" as is the default in phpMyAdmin
151 3612 aaronmk
        If there are multiple part files for a table, and the header is repeated
152
            in each part, make sure each header is EXACTLY the same.
153
             (If the headers are not the same, the CSV concatenation script
154
             assumes the part files don't have individual headers and treats the
155
             subsequent headers as data rows.)
156 4255 aaronmk
        Add <table> to inputs/<datasrc>/import_order.txt before other tables
157 4220 aaronmk
            that depend on it
158 3611 aaronmk
    Install the staging tables:
159 4219 aaronmk
        make inputs/<datasrc>/reinstall quiet=1 &
160
        To view progress: tail -f inputs/<datasrc>/<table>/logs/install.log.sql
161
        View the logs: tail -n +1 inputs/<datasrc>/*/logs/install.log.sql
162 3611 aaronmk
            tail provides a header line with the filename
163
            +1 starts at the first line, to show the whole file
164
        For every file with an error 'column "..." specified more than once':
165 4182 aaronmk
            Add a header override file "+header.<ext>" in <table>/:
166 3611 aaronmk
                Note: The leading "+" should sort it before the flat files.
167
                    "_" unfortunately sorts *after* capital letters in ASCII.
168
                Create a text file containing the header line of the flat files
169
                Add an ! at the beginning of the line
170
                    This signals cat_csv that this is a header override.
171
                For empty names, use their 0-based column # (by convention)
172
                For duplicate names, add a distinguishing suffix
173
                For long names that collided, rename them to <= 63 chars long
174
                Do NOT make readability changes in this step; that is what the
175
                    map spreadsheets (below) are for.
176
                Save
177
        If you made any changes, re-run the install command above
178 6015 aaronmk
    Auto-create the map spreadsheets: make inputs/<datasrc>/
179 3576 aaronmk
    Map each table's columns:
180 4125 aaronmk
        In each <table>/ subdir, for each "via map" map.csv:
181 3576 aaronmk
            Open the map in a spreadsheet editor
182 4125 aaronmk
            Open the "core map" /mappings/Veg+-VegBIEN.csv
183 3576 aaronmk
            In each row of the via map, set the right column to a value from the
184
                left column of the core map
185
            Save
186 4219 aaronmk
        Regenerate the derived maps: make inputs/<datasrc>/
187 3593 aaronmk
    Accept the test cases:
188 4219 aaronmk
        make inputs/<datasrc>/test
189 3593 aaronmk
            When prompted to "Accept new test output", enter y and press ENTER
190 3690 aaronmk
            If you instead get errors, do one of the following for each one:
191
            -   If the error was due to a bug, fix it
192
            -   Add a SQL function that filters or transforms the invalid data
193
            -   Make an empty mapping for the columns that produced the error.
194
                Put something in the Comments column of the map spreadsheet to
195
                prevent the automatic mapper from auto-removing the mapping.
196 3783 aaronmk
            When accepting tests, it's helpful to use WinMerge
197
                (see WinMerge setup below for configuration)
198 4476 aaronmk
        make inputs/<datasrc>/test by_col=1
199
            If you get errors this time, this always indicates a bug, usually in
200 6368 aaronmk
                the VegBIEN unique constraints or column-based import itself

    Refactoring tips:
256
        To rename a table:
257
            In vegbien.sql, do the following:
258
                Replace regexp (?<=_|\b)<old>(?=_|\b) with <new>
259
                    This is necessary because the table name is *everywhere*
260
                Search for <new>
261
                Manually change back any replacements inside comments
262
        To rename a column:
263
            Rename the column: ALTER TABLE <table> RENAME <old> TO <new>;
264
            Recreate any foreign key for the column, removing CONSTRAINT <name>
265
                This resets the foreign key name using the new column name
266 6320 aaronmk
    Creating a poster of the ERD:
267 6326 aaronmk
        Determine the poster size:
268 6320 aaronmk
            Measure the line height (from the bottom of one line to the bottom
269
                of another): 16.3cm/24 lines = 0.679cm
270
            Measure the height of the ERD: 35.4cm*2 = 70.8cm
271
            Zoom in as far as possible
272
            Measure the height of a capital letter: 3.5mm
273
            Measure the line height: 8.5mm
274
            Calculate the text's fraction of the line height: 3.5mm/8.5mm = 0.41
275
            Calculate the text height: 0.679cm*0.41 = 0.28cm
276
            Calculate the text height's fraction of the ERD height:
277
                0.28cm/70.8cm = 0.0040
278
            Measure the text height on the *VegBank* ERD poster: 5.5mm = 0.55cm
279
            Calculate the VegBIEN poster height to make the text the same size:
280
                0.55cm/0.0040 = 137.5cm H; *1in/2.54cm = 54.1in H
281
            The ERD aspect ratio is 11 in W x (2*8.5in H) = 11x17 portrait
282
            Calculate the VegBIEN poster width: 54.1in H*11W/17H = 35.0in W
283
            The minimum VegBIEN poster size is 35x54in portrait

            If the row-based and column-based imports produce different inserted
297
            row counts, this usually means that a table is underconstrained
298
            (the unique indexes don't cover all possible rows).
299
            This can occur if you didn't use COALESCE(field, null_value) around
300
            a nullable field in a unique index. See sql_gen.null_sentinels for
301
            the appropriate null value to use.
