DESCRIPTION

Jira <http://www.atlassian.com/software/jira/> is a proprietary bug tracking system from Atlassian.

This module implements a very thin wrapper around Jira's REST APIs:

Jira Core REST API <https://docs.atlassian.com/software/jira/docs/api/REST/latest/>
This rich API superseded the old Jira SOAP API <http://docs.atlassian.com/software/jira/docs/api/rpc-jira-plugin/latest/com/atlassian/jira/rpc/soap/JiraSoapService.html> which isn't supported anymore as of Jira version 7.

The endpoints of this API have a path prefix of "/rest/api/VERSION".
Jira Service Desk REST API <https://docs.atlassian.com/jira-servicedesk/REST/server/>
This API deals with the objects of the Jira Service Desk application. Its endpoints have a path prefix of "/rest/servicedeskapi".
Jira Software REST API <https://docs.atlassian.com/jira-software/REST/server/>
This API deals with the objects of the Jira Software application. Its endpoints have a path prefix of "/rest/agile/VERSION".

CONSTRUCTORS

new HASHREF

new URL, USERNAME, PASSWORD, REST_CLIENT_CONFIG, ANONYMOUS, PROXY, SSL_VERIFY_NONE

The default constructor can take its arguments from a single hash reference or from a list of positional parameters. The first form is preferred because it lets you specify only the arguments you need. The second form forces you to pass undefined values if you need to pass a specific value to an argument further to the right.

The arguments are described below with the names which must be used as the hash keys:

url
A string or a URI object denoting the base URL of the Jira server. This is a required argument.

The REST methods described below all accept as a first argument the endpoint's path of the specific API method to call. In general you can pass the complete path, beginning with the prefix denoting the particular API to use ("/rest/api/VERSION", "/rest/servicedeskapi", or "/rest/agile/VERSION"). However, you may specify a default API prefix by suffixing the URL with it. For example:
```
    my $jira = JIRA::REST->new({
        url      => 'https://jira.example.net/jira/rest/api/1',
        username => 'myuser',
        password => 'mypass'
    });

    $jira->GET('/rest/api/1/issue/TST-1');
    $jira->GET('/issue/TST-1');
    
```
With this constructor call both GET methods are the same, because the second one does not specify an API prefix. This is useful if you mainly want to use a particular API or if you want to specify a particular version of an API during construction.
username
password
The username and password of a Jira user to use for authentication.

If anonymous is false then, if either username or password isn't defined the module looks them up in either the ".netrc" file or via Config::Identity (which allows "gpg" encrypted credentials).

Config::Identity will look for ~/.jira-identity or ~/.jira. You can change the filename stub from "jira" to a custom stub with the "JIRA_REST_IDENTITY" environment variable.
rest_client_config
A JIRA::REST object uses a REST::Client object to make the REST invocations. This optional argument must be a hash reference that can be fed to the REST::Client constructor. Note that the "url" argument overwrites any value associated with the "host" key in this hash.

As an extension, the hash reference also accepts one additional argument called proxy that is an extension to the REST::Client configuration and will be removed from the hash before passing it on to the REST::Client constructor. However, this argument is deprecated since v0.017 and you should avoid it. Use the following argument instead.
proxy
To use a network proxy set this argument to the string or URI object describing the fully qualified URL (including port) to your network proxy.
ssl_verify_none
Sets the "SSL_verify_mode" and "verify_hostname ssl" options on the underlying REST::Client's user agent to 0, thus disabling them. This allows access to Jira servers that have self-signed certificates that don't pass LWP::UserAgent's verification methods.
anonymous
Tells the module that you want to connect to the specified Jira server with no username or password. This way you can access public Jira servers without needing to authenticate.

new_session OPTIONS

This 'session' constructor first invokes the default constructor, passing to it all the options it receives. Then it makes a "POST /rest/auth/1/session" to login to Jira, creating a user session.

This is particularly useful when interacting with Jira Data Center, because it can use the session cookie to maintain affinity with one of the redundant servers.

When created with this constructor, upon destruction the object makes a "DELETE /rest/auth/1/session" to logout from Jira.

REST METHODS

Jira's REST API documentation lists dozens of "resources" which can be operated via the standard HTTP requests: GET, DELETE, PUT, and POST. JIRA::REST objects implement four methods called GET, DELETE, PUT, and POST to make it easier to invoke and get results from Jira's REST endpoints.

All four methods need two arguments:

RESOURCE
This is the resource's 'path'. For example, in order to GET the list of all fields, you pass "/rest/api/latest/field", and in order to get SLA information about an issue you pass "/rest/servicedeskapi/request/$key/sla".

If you're using a method from Jira Core REST API you may omit the prefix "/rest/api/VERSION". For example, to GET the list of all fields you may pass just "/field".

This argument is required.
QUERY
Some resource methods require or admit parameters which are passed as a "query-string" appended to the resource's path. You may construct the query string and append it to the RESOURCE argument yourself, but it's easier and safer to pass the arguments in a hash. This way the query string is constructed for you and its values are properly percent-encoded <http://en.wikipedia.org/wiki/Percent-encoding> to avoid errors.

This argument is optional for GET and DELETE. For PUT and POST it must be passed explicitly as "undef" if not needed.

The PUT and POST methods accept two more arguments:

VALUE
This is the "entity" being PUT or POSTed. It can be any value, but usually is a hash reference. The value is encoded as a JSON <http://www.json.org/> string using the "JSON::encode" method and sent with a Content-Type of "application/json".

It's usually easy to infer from the Jira REST API documentation which kind of value you should pass to each resource.

This argument is required.
HEADERS
This optional argument allows you to specify extra HTTP headers that should be sent with the request. Each header is specified as a key/value pair in a hash.

All four methods return the value returned by the associated resource's method, as specified in the documentation, decoded according to its content type as follows:

application/json
The majority of the API's resources return JSON values. Those are decoded using the "decode" method of a "JSON" object. Most of the endpoints return hashes, which are returned as a Perl hash reference.
text/plain
Those values are returned as simple strings.

Some endpoints don't return anything. In those cases, the methods return "undef". The methods croak if they get any other type of values in return.

In case of errors (i.e., if the underlying HTTP method return an error code different from 2xx) the methods croak with a multi-line string like this:

    ERROR: <CODE> - <MESSAGE>
    <CONTENT-TYPE>
    <CONTENT>

So, in order to treat errors you must invoke the methods in an eval block or use any of the exception handling Perl modules, such as "Try::Tiny" and "Try::Catch".

GET RESOURCE [, QUERY]

Returns the RESOURCE as a Perl data structure.

DELETE RESOURCE [, QUERY]

Deletes the RESOURCE.

PUT RESOURCE, QUERY, VALUE [, HEADERS]

Creates RESOURCE based on VALUE.

POST RESOURCE, QUERY, VALUE [, HEADERS]

Updates RESOURCE based on VALUE.

UTILITY METHODS

This module provides a few utility methods.

set_search_iterator PARAMS

Sets up an iterator for the search specified by the hash reference PARAMS. It must be called before calls to next_issue.

PARAMS must conform with the query parameters allowed for the "/rest/api/2/search" Jira REST endpoint.

next_issue

This must be called after a call to set_search_iterator. Each call returns a reference to the next issue from the filter. When there are no more issues it returns undef.

Using the set_search_iterator/next_issue utility methods you can iterate through large sets of issues without worrying about the startAt/total/offset attributes in the response from the /search REST endpoint. These methods implement the "paging" algorithm needed to work with those attributes.

attach_files ISSUE FILE...

The "/issue/KEY/attachments" REST endpoint, used to attach files to issues, requires a specific content type encoding which is difficult to come up with just the "REST::Client" interface. This utility method offers an easier interface to attach files to issues.

PERL AND JIRA COMPATIBILITY POLICY

Currently JIRA::REST requires Perl 5.16 and supports Jira 7.0.

We try to be compatible with the Perl native packages of the oldest Ubuntu LTS <https://www.ubuntu.com/info/release-end-of-life> and CentOS <https://wiki.centos.org/About/Product> Linux distributions still getting maintainance updates.

  +-------------+-----------------------+------+
  | End of Life | Distro                | Perl |
  +-------------+-----------------------+------+
  |   2021-04   | Ubuntu 16.04 (xenial) | 5.22 |
  |   2023-04   | Ubuntu 18.04 (bionic) | 5.26 |
  |   2024-07   | CentOS 7              | 5.16 |
  |   2025-04   | Ubuntu 20.04 (focal ) | 5.30 |
  |   2029-05   | CentOS 8              | 5.26 |
  +-------------+-----------------------+------+

As you can see, we're kept behind mostly by the slow pace of CentOS (actually, RHEL) releases.

As for Jira, the policy is very lax. I (the author) only test JIRA::REST on the Jira server installed in the company I work for, which is usually (but not always) at most one year older than the newest released version. I don't have yet an easy way to test it on different versions.
