Bugs
====

The REST API for creating, changing, and getting the details of bugs.

This part of the Bugzilla REST API allows you to file new bugs in Bugzilla and
to get information about existing bugs.

.. _rest_single_bug:

Get Bug
-------

Gets information about particular bugs in the database.

**Request**

To get information about a particular bug using its ID or alias:

.. code-block::  text

   GET /rest/bug/(id_or_alias)

You can also use :ref:`rest_search_bugs` to return more than one bug at a time
by specifying bug IDs as the search terms.

.. code-block:: text

   GET /rest/bug?id=12434,43421

.. _rest_search_bugs:

Search Bugs
-----------

Allows you to search for bugs based on particular criteria.

**Request**

To search for bugs:

.. code-block:: text

   GET /rest/bug

Unless otherwise specified in the description of a parameter, bugs are
returned if they match *exactly* the criteria you specify in these
parameters. That is, we don't match against substrings--if a bug is in
the "Widgets" product and you ask for bugs in the "Widg" product, you
won't get anything.

Criteria are joined in a logical AND. That is, you will be returned
bugs that match *all* of the criteria, not bugs that match *any* of
the criteria.

Each parameter can be either the type it says, or a list of the types
it says. If you pass an array, it means "Give me bugs with *any* of
these values." For example, if you wanted bugs that were in either
the "Foo" or "Bar" products, you'd pass:

.. code-block:: text

   GET /rest/bug?product=Foo&product=Bar

Some Bugzillas may treat your arguments case-sensitively, depending
on what database system they are using. Most commonly, though, Bugzilla is
not case-sensitive with the arguments passed (because MySQL is the
most-common database to use with Bugzilla, and MySQL is not case sensitive).

In addition to the fields listed below, you may also use criteria that
is similar to what is used in the Advanced Search screen of the Bugzilla
UI. This includes fields specified by ``Search by Change History`` and
``Custom Search``. The easiest way to determine what the field names are and what
format Bugzilla expects is to first construct your query using the
Advanced Search UI, execute it and use the query parameters in they URL
as your query for the REST call.

================  ========  =====================================================
name              type      description
================  ========  =====================================================
alias             array     The unique aliases of this bug. An empty array will
                            be returned if this bug has no aliases.
assigned_to       string    The login name of a user that a bug is assigned to.
component         string    The name of the Component that the bug is in. Note
                            that if there are multiple Components with the same
                            name, and you search for that name, bugs in *all*
                            those Components will be returned. If you don't want
                            this, be sure to also specify the ``product`` argument.
creation_time     datetime  Searches for bugs that were created at this time or
                            later. May not be an array.
creator           string    The login name of the user who created the bug. You
                            can also pass this argument with the name
                            ``reporter``, for backwards compatibility with
                            older Bugzillas.
id                int       The numeric ID of the bug.
last_change_time  datetime  Searches for bugs that were modified at this time
                            or later. May not be an array.
limit             int       Limit the number of results returned. If the limit
                            is more than zero and higher than the maximum limit
                            set by the administrator, then the maximum limit will
                            be used instead. If you set the limit equal to zero,
                            then all matching results will be returned instead.
offset            int       Used in conjunction with the ``limit`` argument,
                            ``offset`` defines the starting position for the
                            search. For example, given a search that would
                            return 100 bugs, setting ``limit`` to 10 and
                            ``offset`` to 10 would return bugs 11 through 20
                            from the set of 100.
op_sys            string    The "Operating System" field of a bug.
platform          string    The Platform (sometimes called "Hardware") field of
                            a bug.
priority          string    The Priority field on a bug.
product           string    The name of the Product that the bug is in.
resolution        string    The current resolution--only set if a bug is closed.
                            You can find open bugs by searching for bugs with an
                            empty resolution.
severity          string    The Severity field on a bug.
status            string    The current status of a bug (not including its
                            resolution, if it has one, which is a separate field
                            above).
summary           string    Searches for substrings in the single-line Summary
                            field on bugs. If you specify an array, then bugs
                            whose summaries match *any* of the passed substrings
                            will be returned. Note that unlike searching in the
                            Bugzilla UI, substrings are not split on spaces. So
                            searching for ``foo bar`` will match "This is a foo
                            bar" but not "This foo is a bar". ``['foo', 'bar']``,
                            would, however, match the second item.
tags              string    Searches for a bug with the specified tag. If you
                            specify an array, then any bugs that match *any* of
                            the tags will be returned. Note that tags are
                            personal to the currently logged in user.
target_milestone  string    The Target Milestone field of a bug. Note that even
                            if this Bugzilla does not have the Target Milestone
                            field enabled, you can still search for bugs by
                            Target Milestone. However, it is likely that in that
                            case, most bugs will not have a Target Milestone set
                            (it defaults to "---" when the field isn't enabled).
qa_contact        string    The login name of the bug's QA Contact. Note that
                            even if this Bugzilla does not have the QA Contact
                            field enabled, you can still search for bugs by QA
                            Contact (though it is likely that no bug will have a
                            QA Contact set, if the field is disabled).
url               string    The "URL" field of a bug.
version           string    The Version field of a bug.
whiteboard        string    Search the "Status Whiteboard" field on bugs for a
                            substring. Works the same as the ``summary`` field
                            described above, but searches the Status Whiteboard
                            field.
quicksearch       string    Search for bugs using quicksearch syntax.
================  ========  =====================================================

**Response**

The same as :ref:`rest_single_bug`.

.. _rest_create_bug:

Create Bug
----------

This allows you to create a new bug in Bugzilla. If you specify any
invalid fields, an error will be thrown stating which field is invalid.
If you specify any fields you are not allowed to set, they will just be
set to their defaults or ignored.

You cannot currently set all the items here that you can set on enter_bug.cgi.

The WebService interface may allow you to set things other than those listed
here, but realize that anything undocumented here may likely change in the
future.

**Request**

To create a new bug in Bugzilla.

.. code-block:: text

   POST /rest/bug

.. code-block:: js

   {
     "product" : "TestProduct",
     "component" : "TestComponent",
     "version" : "unspecified",
     "summary" : "'This is a test bug - please disregard",
     "alias" : "SomeAlias",
     "op_sys" : "All",
     "priority" : "P1",
     "rep_platform" : "All"
   }

Some params must be set, or an error will be thrown. These params are
marked in **bold**.

Some parameters can have defaults set in Bugzilla, by the administrator.
If these parameters have defaults set, you can omit them. These parameters
are marked (defaulted).

Clients that want to be able to interact uniformly with multiple
Bugzillas should always set both the params marked required and those
marked (defaulted), because some Bugzillas may not have defaults set
for (defaulted) parameters, and then this method will throw an error
if you don't specify them.

                             Some Bugzilla installations require this to not be
                             blank.

assigned_to         string   A user to assign this bug to, if you don't want it
                             to be assigned to the component owner.
cc                  array    An array of usernames to CC on this bug.
comment_is_private  boolean  If set to true, the description is private,

                             administrator, in the Groups control panel. If you
                             don't specify this argument, then the bug will be
                             added into all the groups that are set as being
                             "Default" for this product. (If you want to avoid
                             that, you should specify ``groups`` as an empty
                             array.)
qa_contact          string   If this installation has QA Contacts enabled, you
                             can set the QA Contact here if you don't want to
                             use the component's default QA Contact.
status              string   The status that this bug should start out as. Note
                             that only certain statuses can be set on bug
                             creation.
resolution          string   If you are filing a closed bug, then you will have
                             to specify a resolution. You cannot currently
                             specify a resolution of ``DUPLICATE``   for new
                             bugs, though. That must be done with
                             :ref:`rest_update_bug`.
target_milestone    string   A valid target milestone for this product.
flags               array    Flags objects to add to the bug. The object format
                             is described in the Flag object below.
==================  =======  ====================================================

Flag object:

To create a flag, at least the ``status`` and the ``type_id`` or ``name`` must
be provided. An optional requestee can be passed if the flag type is requestable
to a specific user.

=========  ======  ==============================================================
name       type    description
=========  ======  ==============================================================
name       string  The name of the flag type.
type_id    int     The internal flag type ID.
status     string  The flags new status (i.e. "?", "+", "-" or "X" to clear flag).
requestee  string  The login of the requestee if the flag type is requestable
                   to a specific user.
=========  ======  ==============================================================

In addition to the above parameters, if your installation has any custom
fields, you can set them just by passing in the name of the field and
its value as a string.

.. _rest_update_bug:

Update Bug
----------

Allows you to update the fields of a bug. Automatically sends emails
out about the changes.

**Request**

To update the fields of a current bug.

.. code-block:: text

   PUT /rest/bug/(id_or_alias)

.. code-block:: js

   {
     "ids" : [35],
     "status" : "IN_PROGRESS",
     "keywords" : {
       "add" : ["funny", "stupid"]
     }
   }

The params to include in the PUT body as well as the returned data format,
are the same as below. You can specify the ID or alias of the bug to update
either in the URL path and/or in the ``ids`` param. You can use both and they
will be combined so you can edit more than one bug at a time.

===============  =====  =========================================================
name             type   description
===============  =====  =========================================================
**id_or_alias**  mixed  An integer bug ID or alias.
**ids**          array  The IDs or aliases of the bugs that you want to modify.
===============  =====  =========================================================

All following fields specify the values you want to set on the bugs you are
updating.

=====================  =======  =================================================
name                   type     description
=====================  =======  =================================================
alias                  object   These specify the aliases of a bug that can be
                                used instead of a bug number when acessing this
                                bug. To set these, you should pass a hash as the
                                value. The object may contain the following
                                items:

                                * ``add`` (array) Aliases to add to this field.
                                * ``remove`` (array) Aliases to remove from this
                                  field. If the aliases are not already in the
                                  field, they will be ignored.
                                * ``set`` (array) An exact set of aliases to set
                                  this field to, overriding the current value.
                                  If you specify ``set``, then ``add`` and
                                  ``remove`` will be ignored.

                                You can only set this if you are modifying a
                                single bug. If there is more than one bug
                                specified in ``ids``, passing in a value for
                                ``alias`` will cause an error to be thrown.

                                For backwards compatibility, you can also
                                specify a single string. This will be treated as
                                if you specified the set key above.
assigned_to            string   The full login name of the user this bug is
                                assigned to.
blocks                 object   (Same as ``depends_on`` below)
depends_on             object   These specify the bugs that this bug blocks or
                                depends on, respectively. To set these, you
                                should pass an object as the value. The object
                                may contain the following items:

                                * ``add`` (array) Bug IDs to add to this field.
                                * ``remove`` (array) Bug IDs to remove from this
                                  field. If the bug IDs are not already in the
                                  field, they will be ignored.
                                * ``set`` (array of) An exact set of bug IDs to
                                  set this field to, overriding the current
                                  value. If you specify ``set``, then ``add``
                                  and ``remove`` will be ignored.
cc                     object   The users on the cc list. To modify this field,
                                pass an object, which may have the following
                                items:

                                * ``add`` (array) User names to add to the CC
                                  list. They must be full user names, and an
                                  error will be thrown if you pass in an invalid
                                  user name.
                                * ``remove`` (array) User names to remove from
                                  the CC list. They must be full user names, and
                                  an error will be thrown if you pass in an
                                  invalid user name.
is_cc_accessible       boolean  Whether or not users in the CC list are allowed
                                to access the bug, even if they aren't in a group
                                that can normally access the bug.
comment                object   A comment on the change. The object may contain
                                the following items:

                                * ``body`` (string) The actual text of the
                                  comment. For compatibility with the parameters
                                  to :ref:`rest_add_comment`, you can also call
                                  this field ``comment``, if you want.
                                * ``is_private`` (boolean) Whether the comment is
                                  private or not. If you try to make a comment
                                  private and you don't have the permission to,
                                  an error will be thrown.
comment_is_private     object   This is how you update the privacy of comments
                                that are already on a bug. This is a object,
                                where the keys are the ``int`` ID of comments
                                (not their count on a bug, like #1, #2, #3, but
                                their globally-unique ID, as returned by
                                :ref:`rest_comments` and the value is a
                                ``boolean`` which specifies whether that comment
                                should become private (``true``) or public
                                (``false``).

                                The comment IDs must be valid for the bug being
                                updated. Thus, it is not practical to use this
                                while updating multiple bugs at once, as a single
                                comment ID will never be valid on multiple bugs.
component              string   The Component the bug is in.
deadline               date     The Deadline field is a date specifying when the
                                bug must be completed by, in the format
                                ``YYYY-MM-DD``.
dupe_of                int      The bug that this bug is a duplicate of. If you
                                want to mark a bug as a duplicate, the safest
                                thing to do is to set this value and *not* set
                                the ``status`` or ``resolutio`` fields. They will
                                automatically be set by Bugzilla to the
                                appropriate values for duplicate bugs.
estimated_time         double   The total estimate of time required to fix the
                                bug, in hours. This is the *total* estimate, not
                                the amount of time remaining to fix it.
flags                  array    An array of Flag change objects. The items needed
                                are described below.
groups                 object   The groups a bug is in. To modify this field,
                                pass an object, which may have the following
                                items:

                                * ``add`` (array) The names of groups to add.
                                  Passing in an invalid group name or a group
                                  that you cannot add to this bug will cause an
                                  error to be thrown.
                                * ``remove`` (array) The names of groups to
                                  remove. Passing in an invalid group name or a
                                  group that you cannot remove from this bug
                                  will cause an error to be thrown.
keywords               object   Keywords on the bug. To modify this field, pass
                                an object, which may have the following items:

                                * ``add`` (array) The names of keywords to add
                                  to the field on the bug. Passing something that
                                  isn't a valid keyword name will cause an error
                                  to be thrown.
                                * ``remove`` (array) The names of keywords to
                                  remove from the field on the bug. Passing
                                  something that isn't a valid keyword name will
                                  cause an error to be thrown.
                                * ``set`` (array) An exact set of keywords to set
                                  the field to, on the bug. Passing something
                                  that isn't a valid keyword name will cause an
                                  error to be thrown. Specifying ``set``
                                  overrides ``add`` and ``remove``.
op_sys                 string   The Operating System ("OS") field on the bug.
platform               string   The Platform or "Hardware" field on the bug.
priority               string   The Priority field on the bug.
product                string   The name of the product that the bug is in. If
                                you change this, you will probably also want to
                                change ``target_milestone``, ``version``, and
                                ``component``, since those have different legal
                                values in every product.

                                If you cannot change the ``target_milestone``
                                field, it will be reset to the default for the
                                product, when you move a bug to a new product.

                                You may also wish to add or remove groups, as
                                which groups are
                                valid on a bug depends on the product. Groups
                                that are not valid in the new product will be
                                automatically removed, and groups which are
                                mandatory in the new product will be automaticaly
                                added, but no other automatic group changes will
                                be done.

                                .. note::
                                   Users can only move a bug into a product if
                                   they would normally have permission to file
                                   new bugs in that product.
qa_contact             string   The full login name of the bug's QA Contact.
is_creator_accessible  boolean  Whether or not the bug's reporter is allowed
                                to access the bug, even if they aren't in a group
                                that can normally access the bug.
remaining_time         double   How much work time is remaining to fix the bug,
                                in hours. If you set ``work_time`` but don't
                                explicitly set ``remaining_time``, then the
                                ``work_time`` will be deducted from the bug's
                                ``remaining_time``.
reset_assigned_to      boolean  If true, the ``assigned_to`` field will be
                                reset to the default for the component that the
                                bug is in. (If you have set the component at the
                                same time as using this, then the component used
                                will be the new component, not the old one.)
reset_qa_contact       boolean  If true, the ``qa_contact`` field will be reset
                                to the default for the component that the bug is
                                in. (If you have set the component at the same
                                time as using this, then the component used will
                                be the new component, not the old one.)
resolution             string   The current resolution. May only be set if you
                                are closing a bug or if you are modifying an
                                already-closed bug. Attempting to set the
                                resolution to *any* value (even an empty or null
                                string) on an open bug will cause an error to be
                                thrown.

                                .. note::
                                   If you change the ``status`` field to an open
                                   status, the resolution field will automatically
                                   be cleared, so you don't have to clear it
                                   manually.
see_also               object   The See Also field on a bug, specifying URLs to
                                bugs in other bug trackers. To modify this field,
                                pass an object, which may have the following
                                items:

                                * ``add`` (array) URLs to add to the field. Each
                                  URL must be a valid URL to a bug-tracker, or
                                  an error will be thrown.
                                * ``remove`` (array) URLs to remove from the
                                  field. Invalid URLs will be ignored.
severity               string   The Severity field of a bug.
status                 string   The status you want to change the bug to. Note
                                that if a bug is changing from open to closed,
                                you should also specify a ``resolution``.
summary                string   The Summary field of the bug.
target_milestone       string   The bug's Target Milestone.
url                    string   The "URL" field of a bug.
version                string   The bug's Version field.
whiteboard             string   The Status Whiteboard field of a bug.
work_time              double   The number of hours worked on this bug as part
                                of this change.
                                If you set ``work_time`` but don't explicitly
                                set ``remaining_time``, then the ``work_time``
                                will be deducted from the bug's ``remaining_time``.
=====================  =======  =================================================

You can also set the value of any custom field by passing its name as
a parameter, and the value to set the field to. For multiple-selection
fields, the value should be an array of strings.

Flag change object:

The following values can be specified. At least the ``status`` and one of
``type_id``, ``id``, or ``name`` must be specified. If a ``type_id`` or
``name`` matches a single currently set flag, the flag will be updated unless
``new`` is specified.

==========  =======  ============================================================
name        type     description
==========  =======  ============================================================
name        string   The name of the flag that will be created or updated.
type_id     int      The internal flag type ID that will be created or updated.
                     You will need to specify the ``type_id`` if more than one
                     flag type of the same name exists.
**status**  string   The flags new status (i.e. "?", "+", "-" or "X" to clear a
                     flag).
requestee   string   The login of the requestee if the flag type is requestable
                     to a specific user.
id          int      Use ID to specify the flag to be updated. You will need to
                     specify the ``id`` if more than one flag is set of the same
                     name.
new         boolean  Set to true if you specifically want a new flag to be
                     created.

``bugs`` (array) This points to an array of objects with the following items:

================  ========  =====================================================
name              type      description
================  ========  =====================================================
id                int       The ID of the bug that was updated.
alias             array     The aliases of the bug that was updated, if this bug
                            has any alias.
last_change_time  datetime  The exact time that this update was done at, for
                            this bug. If no update was done (that is, no fields
                            had their values changed and no comment was added)
                            then this will instead be the last time the bug was
                            updated.
changes           object    The changes that were actually done on this bug. The
                            keys are the names of the fields that were changed,
                            and the values are an object with two keys:

                            * ``added`` (string) The values that were added to
                              this field, possibly a comma-and-space-separated
                              list if multiple values were added.
                            * ``removed`` (string) The values that were removed
                              from this field, possibly a
                              comma-and-space-separated list if multiple values
                              were removed.
================  ========  =====================================================

Currently, some fields are not tracked in changes: ``comment``,
``comment_is_private``, and ``work_time``. This means that they will not
show up in the return value even if they were successfully updated.
This may change in a future version of Bugzilla.
