<p>This addon adds an integrated Job Queue to Odoo.</p>
<p>It allows to postpone method calls executed asynchronously.</p>
<p>Jobs are executed in the background by a <tt class="docutils literal">Jobrunner</tt>, in their own transaction.</p>
<p>Example:</p>
<pre class="code python literal-block">
<span class="kn">from</span> <span class="nn">odoo</span> <span class="kn">import</span> <span class="n">models</span><span class="p">,</span> <span class="n">fields</span><span class="p">,</span> <span class="n">api</span><span class="w">

</pre>
<p>In the snippet of code above, when we call <tt class="docutils literal">button_do_stuff</tt>, a job <strong>capturing
the method and arguments</strong> will be postponed. It will be executed as soon as the
Jobrunner has a free bucket, which can be instantaneous if no other job is
running.</p>
<p>Features:</p>
<ul class="simple">
<li>Views for jobs, jobs are stored in PostgreSQL</li>
<li>Jobrunner: execute the jobs, highly efficient thanks to PostgreSQL’s NOTIFY</li>
<li>Channels: give a capacity for the root channel and its sub-channels and
segregate jobs in them. Allow for instance to restrict heavy jobs to be
executed one at a time while little ones are executed 4 at a times.</li>
<li>Retries: Ability to retry jobs by raising a type of exception</li>
<li>Retry Pattern: the 3 first tries, retry after 10 seconds, the 5 next tries,
retry after 1 minutes, …</li>
<li>Job properties: priorities, estimated time of arrival (ETA), custom
description, number of retries</li>
<li>Related Actions: link an action on the job view, such as open the record
concerned by the job</li>
</ul>

<h1><a class="toc-backref" href="#toc-entry-3">Usage</a></h1>
<p>To use this module, you need to:</p>
<ol class="arabic simple">
<li>Go to <tt class="docutils literal">Job Queue</tt> menu</li>
</ol>
<div class="section" id="developers">

<div class="section" id="delaying-jobs">
<h3><a class="toc-backref" href="#toc-entry-5">Delaying jobs</a></h3>
<p>The fast way to enqueue a job for a method is to use <tt class="docutils literal">with_delay()</tt> on a record
or model:</p>
<pre class="code python literal-block">
<span class="k">def</span> <span class="nf">button_done</span><span class="p">(</span><span class="bp">self</span><span class="p">):</span><span class="w">
</span> <span class="bp">self</span><span class="o">.</span><span class="n">with_delay</span><span class="p">()</span><span class="o">.</span><span class="n">print_confirmation_document</span><span class="p">(</span><span class="bp">self</span><span class="o">.</span><span class="n">state</span><span class="p">)</span><span class="w">
</span> <span class="bp">self</span><span class="o">.</span><span class="n">write</span><span class="p">({</span><span class="s2">&quot;state&quot;</span><span class="p">:</span> <span class="s2">&quot;done&quot;</span><span class="p">})</span><span class="w">
</span> <span class="k">return</span> <span class="kc">True</span>
</pre>
<p>Here, the method <tt class="docutils literal">print_confirmation_document()</tt> will be executed asynchronously
as a job. <tt class="docutils literal">with_delay()</tt> can take several parameters to define more precisely how
the job is executed (priority, …).</p>
<p>All the arguments passed to the method being delayed are stored in the job and
passed to the method when it is executed asynchronously, including <tt class="docutils literal">self</tt>, so
the current record is maintained during the job execution (warning: the context
is not kept).</p>
<p>Dependencies can be expressed between jobs. To start a graph of jobs, use <tt class="docutils literal">delayable()</tt>
on a record or model. The following is the equivalent of <tt class="docutils literal">with_delay()</tt> but using the
long form:</p>
<pre class="code python literal-block">
<span class="k">def</span> <span class="nf">button_done</span><span class="p">(</span><span class="bp">self</span><span class="p">):</span><span class="w">
</span> <span class="n">delayable</span> <span class="o">=</span> <span class="bp">self</span><span class="o">.</span><span class="n">delayable</span><span class="p">()</span><span class="w">
</span> <span class="n">delayable</span><span class="o">.</span><span class="n">print_confirmation_document</span><span class="p">(</span><span class="bp">self</span><span class="o">.</span><span class="n">state</span><span class="p">)</span><span class="w">
</span> <span class="n">delayable</span><span class="o">.</span><span class="n">delay</span><span class="p">()</span><span class="w">
</span> <span class="bp">self</span><span class="o">.</span><span class="n">write</span><span class="p">({</span><span class="s2">&quot;state&quot;</span><span class="p">:</span> <span class="s2">&quot;done&quot;</span><span class="p">})</span><span class="w">
</span> <span class="k">return</span> <span class="kc">True</span>
</pre>
<p>Methods of Delayable objects return itself, so it can be used as a builder pattern,
which in some cases allow to build the jobs dynamically:</p>
<pre class="code python literal-block">
<span class="k">def</span> <span class="nf">button_generate_simple_with_delayable</span><span class="p">(</span><span class="bp">self</span><span class="p">):</span><span class="w">

<p>Delayables can be chained to form more complex graphs using the <tt class="docutils literal">chain()</tt> and
<tt class="docutils literal">group()</tt> primitives.
A chain represents a sequence of jobs to execute in order, a group represents
jobs which can be executed in parallel. Using <tt class="docutils literal">chain()</tt> has the same effect as
using several nested <tt class="docutils literal">on_done()</tt> but is more readable. Both can be combined to
form a graph, for instance we can group [A] of jobs, which blocks another group
[B] of jobs. When and only when all the jobs of the group [A] are executed, the
jobs of the group [B] are executed. The code would look like:</p>

</pre>
<p>When a failure happens in a graph of jobs, the execution of the jobs that depend on the
failed job stops. They remain in a state <tt class="docutils literal">wait_dependencies</tt> until their “parent” job is
successful. This can happen in two ways: either the parent job retries and is successful
on a second try, either the parent job is manually “set to done” by a user. In these two
cases, the dependency is resolved and the graph will continue to be processed. Alternatively,
the failed job and all its dependent jobs can be canceled by a user. The other jobs of the
graph that do not depend on the failed job continue their execution in any case.</p>
<p>Note: <tt class="docutils literal">delay()</tt> must be called on the delayable, chain, or group which is at the top
of the graph. In the example above, if it was called on <tt class="docutils literal">group_a</tt>, then <tt class="docutils literal">group_b</tt>
would never be delayed (but a warning would be shown).</p>

<p>The general form for the <tt class="docutils literal">name</tt> is: <tt class="docutils literal"><span class="pre">&lt;model.name&gt;.method</span></tt>.</p>
<p>The channel, related action and retry pattern options are optional, they are
documented below.</p>
<p>When writing modules, if 2+ modules add a job function or channel with the same
name (and parent for channels), they’ll be merged in the same record, even if
they have different xmlids. On uninstall, the merged record is deleted when all
the modules using it are uninstalled.</p>
<p><strong>Job function: model</strong></p>
<p>If the function is defined in an abstract model, you can not write
<tt class="docutils literal">&lt;field <span class="pre">name=&quot;model_id&quot;</span> <span class="pre">ref=&quot;xml_id_of_the_abstract_model&quot;&lt;/field&gt;</span></tt>
but you have to define a function for each model that inherits from the abstract model.</p>
<p><strong>Job function: channel</strong></p>
<p>The channel where the job will be delayed. The default channel is <tt class="docutils literal">root</tt>.</p>
<p><strong>Job function: related action</strong></p>
<p>The <em>Related Action</em> appears as a button on the Job’s view.
The button will execute the defined action.</p>
<p>The default one is to open the view of the record related to the job (form view
when there is a single record, list view for several records).
In many cases, the default related action is enough and doesn’t need
customization, but it can be customized by providing a dictionary on the job
function:</p>
<pre class="code python literal-block">
<span class="p">{</span><span class="w">
</span> <span class="s2">&quot;enable&quot;</span><span class="p">:</span> <span class="kc">False</span><span class="p">,</span><span class="w">

</pre>
<ul class="simple">
<li><tt class="docutils literal">enable</tt>: when <tt class="docutils literal">False</tt>, the button has no effect (default: <tt class="docutils literal">True</tt>)</li>
<li><tt class="docutils literal">func_name</tt>: name of the method on <tt class="docutils literal">queue.job</tt> that returns an action</li>

</pre>
<p><strong>Job function: retry pattern</strong></p>
<p>When a job fails with a retryable error type, it is automatically
retried later. By default, the retry is always 10 minutes later.</p>
<p>A retry pattern can be configured on the job function. What a pattern represents
is “from X tries, postpone to Y seconds”. It is expressed as a dictionary where
keys are tries and values are seconds to postpone as integers:</p>
<pre class="code python literal-block">
<span class="p">{</span><span class="w">
</span> <span class="mi">1</span><span class="p">:</span> <span class="mi">10</span><span class="p">,</span><span class="w">
</span> <span class="mi">5</span><span class="p">:</span> <span class="mi">20</span><span class="p">,</span><span class="w">
</span> <span class="mi">10</span><span class="p">:</span> <span class="mi">30</span><span class="p">,</span><span class="w">
</span> <span class="mi">15</span><span class="p">:</span> <span class="mi">300</span><span class="p">,</span><span class="w">
</span><span class="p">}</span>
</pre>
<p>Based on this configuration, we can tell that:</p>
<ul class="simple">
<li>5 first retries are postponed 10 seconds later</li>
<li>retries 5 to 10 postponed 20 seconds later</li>
<li>retries 10 to 15 postponed 30 seconds later</li>
<li>all subsequent retries postponed 5 minutes later</li>
</ul>
<p><strong>Job Context</strong></p>
<p>The context of the recordset of the job, or any recordset passed in arguments of
a job, is transferred to the job according to an allow-list.</p>
<p>The default allow-list is <cite>(“tz”, “lang”, “allowed_company_ids”, “force_company”, “active_test”)</cite>. It can
be customized in <tt class="docutils literal">Base._job_prepare_context_before_enqueue_keys</tt>.
<strong>Bypass jobs on running Odoo</strong></p>
<p>When you are developing (ie: connector modules) you might want
to bypass the queue job and run your code immediately.</p>
<p>To do so you can set <cite>QUEUE_JOB__NO_DELAY=1</cite> in your enviroment.</p>
<p><strong>Bypass jobs in tests</strong></p>
<p>When writing tests on job-related methods is always tricky to deal with
delayed recordsets. To make your testing life easier
you can set <cite>queue_job__no_delay=True</cite> in the context.</p>
<p>Tip: you can do this at test case level like this</p>
<pre class="code python literal-block">
<span class="nd">&#64;classmethod</span><span class="w">
</span><span class="k">def</span> <span class="nf">setUpClass</span><span class="p">(</span><span class="bp">cls</span><span class="p">):</span><span class="w">

</span> <span class="p">))</span>
</pre>
<p>Then all your tests execute the job methods synchronously
without delaying any jobs.</p>
</div>
<div class="section" id="testing">
<h3><a class="toc-backref" href="#toc-entry-8">Testing</a></h3>
<p><strong>Asserting enqueued jobs</strong></p>
<p>The recommended way to test jobs, rather than running them directly and synchronously is to
split the tests in two parts:</p>
<blockquote>
<ul class="simple">
<li>one test where the job is mocked (trap jobs with <tt class="docutils literal">trap_jobs()</tt> and the test
only verifies that the job has been delayed with the expected arguments</li>
<li>one test that only calls the method of the job synchronously, to validate the
proper behavior of this method only</li>
</ul>
</blockquote>
<p>Proceeding this way means that you can prove that jobs will be enqueued properly
at runtime, and it ensures your code does not have a different behavior in tests
and in production (because running your jobs synchronously may have a different
behavior as they are in the same transaction / in the middle of the method).
Additionally, it gives more control on the arguments you want to pass when
calling the job’s method (synchronously, this time, in the second type of
tests), and it makes tests smaller.</p>
<p>The best way to run such assertions on the enqueued jobs is to use
<tt class="docutils literal">odoo.addons.queue_job.tests.common.trap_jobs()</tt>.</p>

<p><strong>Execute jobs synchronously when running Odoo</strong></p>
<p>When you are developing (ie: connector modules) you might want
to bypass the queue job and run your code immediately.</p>
<p>To do so you can set <tt class="docutils literal">QUEUE_JOB__NO_DELAY=1</tt> in your environment.</p>
<div class="admonition warning">
<p class="first admonition-title">Warning</p>
<p class="last">Do not do this in production</p>
</div>
<p><strong>Execute jobs synchronously in tests</strong></p>
<p>You should use <tt class="docutils literal">trap_jobs</tt>, really, but if for any reason you could not use it,
and still need to have job methods executed synchronously in your tests, you can
do so by setting <tt class="docutils literal">queue_job__no_delay=True</tt> in the context.</p>
<p>Tip: you can do this at test case level like this</p>
<pre class="code python literal-block">
<span class="nd">&#64;classmethod</span><span class="w">
</span><span class="k">def</span> <span class="nf">setUpClass</span><span class="p">(</span><span class="bp">cls</span><span class="p">):</span><span class="w">
</span> <span class="nb">super</span><span class="p">()</span><span class="o">.</span><span class="n">setUpClass</span><span class="p">()</span><span class="w">
</span> <span class="bp">cls</span><span class="o">.</span><span class="n">env</span> <span class="o">=</span> <span class="bp">cls</span><span class="o">.</span><span class="n">env</span><span class="p">(</span><span class="n">context</span><span class="o">=</span><span class="nb">dict</span><span class="p">(</span><span class="w">
</span> <span class="bp">cls</span><span class="o">.</span><span class="n">env</span><span class="o">.</span><span class="n">context</span><span class="p">,</span><span class="w">
</span> <span class="n">queue_job__no_delay</span><span class="o">=</span><span class="kc">True</span><span class="p">,</span> <span class="c1"># no jobs thanks</span><span class="w">
</span> <span class="p">))</span>
</pre>
<p>Then all your tests execute the job methods synchronously without delaying any
jobs.</p>
<p>In tests you’ll have to mute the logger like:</p>
<blockquote>
&#64;mute_logger(‘odoo.addons.queue_job.models.base’)</blockquote>
<div class="admonition note">
<p class="first admonition-title">Note</p>
<p class="last">in graphs of jobs, the <tt class="docutils literal">queue_job__no_delay</tt> context key must be in at
least one job’s env of the graph for the whole graph to be executed synchronously</p>

<h3><a class="toc-backref" href="#toc-entry-9">Tips and tricks</a></h3>
<ul class="simple">
<li><strong>Idempotency</strong> (<a class="reference external" href="https://www.restapitutorial.com/lessons/idempotency.html">https://www.restapitutorial.com/lessons/idempotency.html</a>): The queue_job should be idempotent so they can be retried several times without impact on the data.</li>
<li><strong>The job should test at the very beginning its relevance</strong>: the moment the job will be executed is unknown by design. So the first task of a job should be to check if the related work is still relevant at the moment of the execution.</li>
</ul>
</div>
<div class="section" id="patterns">
<h3><a class="toc-backref" href="#toc-entry-10">Patterns</a></h3>
<p>Through the time, two main patterns emerged:</p>
<ol class="arabic simple">
<li>For data exposed to users, a model should store the data and the model should be the creator of the job. The job is kept hidden from the users</li>
<li>For technical data, that are not exposed to the users, it is generally alright to create directly jobs with data passed as arguments to the job, without intermediary models.</li>
</ol>

<div class="section" id="known-issues-roadmap">
<h1><a class="toc-backref" href="#toc-entry-11">Known issues / Roadmap</a></h1>
<ul class="simple">
<li>After creating a new database or installing <tt class="docutils literal">queue_job</tt> on an
existing database, Odoo must be restarted for the runner to detect it.</li>
<li>When Odoo shuts down normally, it waits for running jobs to finish.
However, when the Odoo server crashes or is otherwise force-stopped,
running jobs are interrupted while the runner has no chance to know
they have been aborted. In such situations, jobs may remain in
<tt class="docutils literal">started</tt> or <tt class="docutils literal">enqueued</tt> state after the Odoo server is halted.
Since the runner has no way to know if they are actually running or
not, and does not know for sure if it is safe to restart the jobs,
it does not attempt to restart them automatically. Such stale jobs
therefore fill the running queue and prevent other jobs to start.
You must therefore requeue them manually, either from the Jobs view,
or by running the following SQL statement <em>before starting Odoo</em>:</li>
