6.1.3. Bugs — Bugzilla Harmony documentation

# 6.1.3. 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.

## 6.1.3.1. Get Bug

Gets information about particular bugs in the database.

Request

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

    GET /rest/bug/(id_or_alias)

You can also use Search Bugs to return more than one bug at a time by specifying bug IDs as the search terms.

    GET /rest/bug?id=12434,43421

name | type | description
--- | --- | ---
id_or_alias | mixed | An integer bug ID or a bug alias string.

## 6.1.3.3. Search Bugs

Allows you to search for bugs based on particular criteria.

Request

To search for bugs:

    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:

    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 | string | The unique alias of this bug. A `null` value will be returned if this bug has no alias.
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.
count_only | boolean | If set to true, an object with a single key called “bug_count” will be returned which is the number of bugs that matched the search.
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.
description | string | The description (initial comment) of the bug.
filed_via | string | Searches for bugs that were created with this method.
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 value is unset, zero or greater than the maximum value set by the administrator, which is 10,000 by default, then the maximum value will be used instead. This is a preventive measure against DoS-like attacks on Bugzilla. Use the `offset` argument described below to retrieve more results.
longdescs.count | int | The number of comments a bug has. The bug’s description is the first comment. For example, to find bugs which someone has commented on after they have been filed, search on `longdescs.count` greater than 1.
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.
quicksearch | string | Search for bugs using quicksearch syntax.
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).
triage_owner | string | The login name of the Triage Owner of a bug’s component.
type | string | The Type field on a bug.
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.

Response

The same as Get Bug.

Errors

If you specify an invalid value for a particular field, you just won’t get any results for that value.

- 1000 (Parameters Required) You may not search without any search terms.

## 6.1.3.4. 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.

    POST /rest/bug

    {
      "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.

name | type | description
--- | --- | ---
product | string | The name of the product the bug is being filed against.
component | string | The name of a component in the product above.
summary | string | A brief description of the bug being filed.
version | string | A version of the product above; the version the bug was found in.
description | string | (defaulted) The description (initial comment) of the bug. Some Bugzilla installations require this to not be blank.
filed_via | string | (defaulted) How the bug is being filed. It will be `api` by default when filing through the API.
op_sys | string | (defaulted) The operating system the bug was discovered on.
platform | string | (defaulted) What type of hardware the bug was experienced on.
priority | string | (defaulted) What order the bug will be fixed in by the developer, compared to the developer’s other bugs.
severity | string | (defaulted) How severe the bug is.
type | string | (defaulted) The basic category of the bug. Some Bugzilla installations require this to be specified.
alias | string | The alias for the bug that can be used instead of a bug number when accessing this bug. Must be unique in all of this Bugzilla.
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, otherwise it is assumed to be public.
groups | array | An array of group names to put this bug into. You can see valid group names on the Permissions tab of the Preferences screen, or, if you are an 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 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.
keywords | array | One or more valid keywords to add to this bug.
dependson | array | One or more valid bug ids that this bug depends on.
blocked | array | One or more valid bug ids that this bug blocks.

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).

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.

Response

    {
      "id" : 12345
    }

name | type | description
--- | --- | ---
id | int | This is the ID of the newly-filed bug.

## 6.1.3.5. 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.

    PUT /rest/bug/(id_or_alias)

    {
      "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 | string | The alias for the bug that can be used instead of a bug number when accessing this bug. Must be unique in all of this Bugzilla.
assigned_to | string | The full login name of the user this bug is assigned to.
blocks | object | (Same as `regressed_by` below)
depends_on | object | (Same as `regressed_by` below)
regressions | object | (Same as `regressed_by` below)
regressed_by | object | These specify the bugs that this bug blocks, depends on, regresses, or is regressed by, 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 Create Comments, 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 Get 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 `resolution` 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 automatically 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.
type | string | The Type field on the bug.
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.

Response

    {
      "bugs" : [
        {
          "alias" : null,
          "changes" : {
            "keywords" : {
              "added" : "funny, stupid",
              "removed" : ""
            },
              "status" : {
                "added" : "IN_PROGRESS",
                "removed" : "CONFIRMED"
            }
          },
          "id" : 35,
          "last_change_time" : "2014-09-29T14:25:35Z"
        }
      ]
    }

`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 | string | The alias 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.
