DB API
This is the documentation of the PGXN database functions available to the "pgxn" user, which is the database user as which the app will connect to the database. It's generated using gendoc, a simple SQL file parser that looks for function declarations and embedded MultiMarkdown. It is then run through MultiMarkdown.pl to generate HTML for this page. (Alas, the GitHub markup library does not (yet) support MultiMarkdown).

% SELECT rand_str_of_len(12);
rand_str_of_len
─────────────────
i5cvbMF849hp
Returns a random string of ASCII alphanumeric characters of the specified
length. Borrowed from
Depesz.
Used internally by forgot_password() to generate tokens.
- Parameters
-
- IN nick LABEL
- Returns
- TEXT
% SELECT forgot_password('theory');
forgot_password
──────────────────────────────
{G8Gxz,justatheory@pgxn.org}
Creates a password reset token for the specified nickname. The user must be
active. The return value is a two-element array. The first value is the token,
and the second the email address of the user. The token will be set to expire
1 day from creation. Returns NULL if the token cannot be created (because no
user exists for the specified nickname or the user is not ative).
- Parameters
-
- IN string TEXT
- Returns
- TEXT
% SELECT json_key('foo');
json_key
──────────
"foo"
Like json_string(), this function encodes a text value as a JSON string and
returns the string. The difference is that NULL is treated as illegal
(because it cannot be used as a JSON key) and will thus throw an exception.
- Parameters
-
- IN val TEXT
- IN def TEXT DEFAULT 'null'
- Returns
- TEXT
% SELECT json_value('foo'), json_value(NULL), json_value(NULL, 'default'),
json_value(NULL, NULL);
json_value │ json_value │ json_value │ json_value
────────────┼────────────┼────────────┼────────────
"foo" │ null │ default │
Encodes a text value as a JSON string. If the string is NULL, the second
argument will be used as a fallback. If there is no second argument, it will
fall back to "null".
- Parameters
-
- IN nick LABEL
- IN coowner LABEL
- IN exts TEXT[]
- Returns
- BOOLEAN

───────────────────
t
Grants co-ownership to one or more extensions. The first argument is the nickname of the uesr inserting the co-owner. Said user must either be and admin or own all of the specified extensions. The second argument is the nickname of the user being granted co-ownership. This name must not be the same name as the owner. The third argument is an array of the names of the extensions to which co-ownership is to be granted.

revoke_coownership
────────────────────
t
Remove co-ownership permission to the specified extensions. The first argument is the nickname of the user removing co-ownership. Said user must either be and admin, own all of the specified extensions, or be removing co-ownership from itself. The second argument is the nickname of the user being for whom co-ownership is being removed. The third argument is an array of the names of the extensions from which co-ownership is to be removed.
- Parameters

────────────────────
t
Transfer ownership of the specified extensions to a new owner. The first argument is the nickname of the uesr performing the transfer. Said user must either be and admin or own all of the specified extensions. The second argument is the nickname of the user being given ownership. This name must not be the same name as the owner. The third argument is an array of the names of the extensions to which ownership is to be transfered.

update_mirror
───────────────
t
(1 row)
Updates a mirror. The user specified as the first parameter must be an
administrator or else an exception will be thrown. The old_uri parameter
must contain the existing URI of the mirror and is required. All other
paramters are optional. Returns true on succesful update and false on failure,
which will happen if the existing URI cannot be found in the database.
- Parameters
-
- IN deleter LABEL
- IN uri URI
- Returns
- BOOLEAN
% SELECT delete_mirror('theory', 'https://kineticode.com/pgxn/');
delete_mirror

- Parameters
-
- IN email EMAIL
- Returns
- TEXT
% SELECT munge_email('foo@bar.com');
munge_email
─────────────
bar.com|foo
Munges an email address. This is for use in mirrors.json, just to have a bit
of obfuscation. All it does is move the username to the end, separated from
the domain name by a pipe. So "foo@bar.com" becomes "bar.com|foo".

Returns a table of all the system stats. The first column, stats_name,
contains the name of the statistics file. The second column contains the
statistics in JSON format.
- Parameters
-
- IN dist TERM
- IN version SEMVER
- Returns
- TABLE ( template TEXT, subject TEXT, json TEXT )
Returns all of the metadata updates to be stored for a given distribution. The
output is the same as for add_distribution(), but the distribution must
already exist in the database. Useful for reindexing a distribution or
re-generating metadata files. If the distribution or its version do not exist,
no rows will be returned.
- Parameters
-
- IN dist TERM
- IN version SEMVER
- Returns
- VOID
SELECT check_dist_version('pair', '1.2.0');
check_dist_version
--------------------
Checks to see if a distribution name and version is allowed to be created or updated. Returns no value if the version is allowed, and throws an exception if it is not. A new version of a distribution can be created or updated if any of the following rules apply to the distribution:
- No other version exists
- The new version is greater than or equal to all existing versions (x.y.z)
- The new version is greater than or equal to all versions with the same major and minor parts (x.y)
- The new version is greater than or equal to all versions with the same major parts (x)
The first case applies if it's a new distribution name.
The second is the usual expected case, where the new version is the highest
The third case applies for updating an existing minor version. For example, if there are existing versions 1.2.3 and 1.4.2, a new version 1.2.4 would be allowed, but not 1.2.2 or 1.3.0.
The fourth case applies for updating an existing major version. For example, if there are existing versions 1.2.6 and 2.0.4, a new version 1.3.0 would be allowed, but not 0.10.0.
- Parameters

Creates a new distribution, returning all of the JSON that needs to be written
to the mirror in order for the distribution to be indexed. The nickname of the
uploading user must be passed as the first argument. The SHA1 of the
distribution file must be passed as the second argument. All other metadata is
parsed from the JSON string, which should contain the complete contents of the
distribution's META.json file. The required keys in the JSON metadata are:
- name
- The name of the extension.
- version
-
The extension version string. Will be normalized by
clean_semver(). - license
- The license or licenses.
- maintainer
- The distribution maintainer or maintainers.
- abstract
- Short description of the distribution.
See the PGXN Meta Spec for the complete list of specified keys.
With this data, add_distribution() does the following things:
Parses the JSON string and validates that all required keys are present. Throws an exception if they're not.
Creates a new metadata structure and stores all the required and many of the optional meta spec keys, as well as the SHA1 of the distribution file, the release date, and the user's nickname.
Normalizes all of the version numbers found in the metadata into compliant semantic version strings. See
SemVer->normalfor details on how non-compliant version strings are converted. Versions that cannot be normalized will trigger an exception.Specifies that the provided extension is the same as the distribution name and version if no "provides" metadata is present in the distribution metadata.
Validates that the uploading user is owner or co-owner of all provided extensions. If no one is listed as owner of one or more included extensions, the user will be assigned ownership. If the user is not owner or co-owner of any included extensions, an exception will be thrown.
Validates that the release version is greater than in any previous release, and that all extension versions are greater than or equal to versions in any previous releases.
Inserts the distribution data into the
distributionstable.Inserts records for all included extensions into the
distribution_extensionstable.Inserts records for all associated tags into the
distribution_tagstable.
Once all this work is done, add_distribution() returns a relation with the
following columns:
- template
- Name of a mirror URI template.
- subject
- The subject of the metadata to be written, such as the name of a distribution, extension, user, tag, or statistics.
- json
- The JSON-formatted metadata for the subject, which the application should write to the fie specified by the template.
- Parameters
-
- IN nick LABEL
- IN sha1 TEXT
- IN meta TEXT
- Returns
- TABLE ( template TEXT, subject TEXT, json TEXT )
Exactly like add_distribution(), with the same arguments and rules, but
updates an existing distribution, rather than creating a new one. This may be
useful if the format of the generated META.json file changes: just call this
method for all existing distributions to have then reindexed with the new
format.
Note that, for all included extensions, nick must have ownership or no one
must, in which case the user will be given ownership. This might be an issue
when re-indexing a distribution containing extensions that the user owned at
the time the distribution was released, but no longer does. In that case,
you'll probably need to grant the user temporary co-ownership of all
extensions, re-index, and then revoke.
- Parameters
-
- IN nickname LABEL
- IN password TEXT
- IN full_name TEXT DEFAULT ''
- IN email EMAIL DEFAULT NULL
- IN uri URI DEFAULT NULL
- IN twitter CITEXT DEFAULT NULL
- IN why TEXT DEFAULT NULL
- Returns
- BOOLEAN
% SELECT insert_user(
nickname := 'theory',
password := '***',
full_name := 'David Wheeler',
email := 'theory@pgxn.org',
uri := 'https://justatheory.com/',
twitter := 'theory',
why := 'Because I’m a bitchin’ Pg developer, yo.'
);
insert_user
─────────────
t
Inserts a new user into the database. The nickname must not already exist or
an exception will be thrown. The password must be at least four characters
long or an exception will be thrown. The status will be set to "new" and the
set_by set to the new user's nickname. The other parameters are:
- full_name
- The full name of the user.
- The email address of the user. Must be a valid email address as verified by Email::Valid.
- uri
- Optional URI for the user. Should be a valid URI as verified by Data::Validate::URI.
- Optional Twitter username. Case-insensitive. A leading "@" will be removed.
- why
- Optional text from the user explaining why she should be allowed access.
Returns true if the user was inserted, and false if not.
- Parameters
-
- IN nickname LABEL
- IN oldpass TEXT
- IN newpass TEXT
- Returns
- BOOLEAN
% SELECT change_password('strongrrl', '****', 'whatever');
change_password
─────────────────
t
Changes a user's password. The user must be active, and the old password must match the existing password for the nickname or the password will not be set. The password must be at least four charcters long or an exception will be thrown. Returns true if the password was changed and false if it was not.
- Parameters
-
- IN setter LABEL
- IN nickname LABEL
- IN reset_span INTERVAL
- Returns
- TEXT
% SELECT clear_password('theory', 'strongrrl', '1 week');
clear_password
────────────────────────────
{1bhAo,strongrrl@pgxn.org}
Clears the password for the specified nickname and returns a password reset
token that's good for the specified reset span. The setter must be an admin;
an exception will be thrown if it is not. The user must be active. The return
value is a two-element array. The first value is the token, and the second the
email address of the user. The token will be set to expire 1 day from creation.
Returns NULL if the token cannot be created (because no user exists for the
specified nickname or the user is not ative).
- Parameters
-
- IN nickname LABEL
- IN full_name TEXT DEFAULT NULL
- IN email EMAIL DEFAULT NULL
- IN uri URI DEFAULT NULL
- IN twitter CITEXT DEFAULT NULL
- Returns
- BOOLEAN
% SELECT update_user(
nickname := 'theory',
full_name := 'David E. Wheeler',
email := 'justatheory@pgxn.org',
uri := 'https://www.justatheory.com/',
twitter :- 'theory'
);
update_user
─────────────
t
Update the specified user. The user must be active. The nickname cannot be
changed. The password can only be changed via change_password() or
reset_password(). Pass other attributes as:
- full_name
- The full name of the user.
- The email address of the user. Must be a valid email address as verified by Email::Valid.
- uri
- Optional URI for the user. Should be a valid URI as verified by Data::Validate::URI.
- Optional Twitter username. A leading "@" wil be removed.
Returns true if the user was updated, and false if not.
- Parameters
-
- IN nickname LABEL
- Returns
- BOOLEAN
% SELECT log_visit('theory');
log_visit
───────────
t
Log the visit for the specified user. At this point, that just means that
users.visited_at gets set to the current time.

t
Sets a user's status. The status may be one of "active", "inactive", or
"deleted". The nickname of the user who sets the status must be passed as the
first argument, and that user must be an administrator or an exception will be
thrown. That nickname will be stored in the set_by column. Users cannot
change their own status; if setter and nick are the same, an exception
will be thrown. Returns true if the status was set, and false if not. If the
status is already set to the specified value, the record will not be updated
and false will be returned.
- Parameters
-

- IN nickname LABEL
- IN set_to BOOLEAN
- Returns
- BOOLEAN
% select set_user_admin('admin', 'strongrrl', true);
set_user_admin
────────────────
t
Sets a user's administrator flag. The nickname of the user who does so must be
