= Gerrit Code Review - Review Labels
|
|
|
|
As part of the code review process, reviewers score each change with
|
|
values for each label configured for the project. The label values that
|
|
a given user is allowed to set are defined according to the
|
|
link:access-control.html#category_review_labels[access controls]. Gerrit
|
|
comes pre-configured with the Code-Review label that can be granted to
|
|
groups within projects, enabling functionality for that group's members.
|
|
|
|
|
|
[[label_Code-Review]]
|
|
== Label: Code-Review
|
|
|
|
The Code-Review label is configured upon the creation of a Gerrit
|
|
instance. It may have any meaning the project desires. It was
|
|
originally invented by the Android Open Source Project to mean
|
|
'I read the code and it seems reasonably correct'.
|
|
|
|
The range of values is:
|
|
|
|
* -2 This shall not be merged
|
|
+
|
|
The code is so horribly incorrect/buggy/broken that it must not be
|
|
submitted to this project, or to this branch. This value is valid
|
|
across all patch sets in the same change, i.e. the reviewer must
|
|
actively change his/her review to something else before the change
|
|
is submittable.
|
|
+
|
|
*Any -2 blocks submit.*
|
|
|
|
* -1 I would prefer this is not merged as is
|
|
+
|
|
The code doesn't look right, or could be done differently, but
|
|
the reviewer is willing to live with it as-is if another reviewer
|
|
accepts it, perhaps because it is better than what is currently in
|
|
the project. Often this is also used by contributors who don't like
|
|
the change, but also aren't responsible for the project long-term
|
|
and thus don't have final say on change submission.
|
|
+
|
|
Does not block submit.
|
|
|
|
* 0 No score
|
|
+
|
|
Didn't try to perform the code review task, or glanced over it but
|
|
don't have an informed opinion yet.
|
|
|
|
* +1 Looks good to me, but someone else must approve
|
|
+
|
|
The code looks right to this reviewer, but the reviewer doesn't
|
|
have access to the `+2` value for this category. Often this is
|
|
used by contributors to a project who were able to review the change
|
|
and like what it is doing, but don't have final approval over what
|
|
gets submitted.
|
|
|
|
* +2 Looks good to me, approved
|
|
+
|
|
Basically the same as `+1`, but for those who have final say over
|
|
how the project will develop.
|
|
+
|
|
*Any +2 enables submit.*
|
|
|
|
For a change to be submittable, the latest patch set must have a
|
|
`+2 Looks good to me, approved` in this category, and no
|
|
`-2 Do not submit`. Thus `-2` on any patch set can block a submit,
|
|
while `+2` on the latest patch set can enable it.
|
|
|
|
If a Gerrit installation does not wish to use this label in any project,
|
|
the `[label "Code-Review"]` section can be deleted from `project.config`
|
|
in `All-Projects`.
|
|
|
|
If a Gerrit installation or project wants to modify the description text
|
|
associated with these label values, the text can be updated in the
|
|
`label.Code-Review.value` fields in `project.config`.
|
|
|
|
Additional entries could be added to `label.Code-Review.value` to
|
|
further extend the negative and positive range, but there is likely
|
|
little value in doing so as this only expands the middle region. This
|
|
label is a `MaxWithBlock` type, which means that the lowest negative
|
|
value if present blocks a submit, while the highest positive value is
|
|
required to enable submit.
|
|
|
|
[[label_Verified]]
|
|
== Label: Verified
|
|
|
|
The Verified label was originally invented by the Android Open Source
|
|
Project to mean 'compiles, passes basic unit tests'. Some CI tools
|
|
expect to use the Verified label to vote on a change after running.
|
|
|
|
During site initialization the administrator may have chosen to
|
|
configure the default Verified label for all projects. In case it is
|
|
desired to configure it at a later time, administrators can do this by
|
|
adding the following to `project.config` in `All-Projects`:
|
|
|
|
----
|
|
[label "Verified"]
|
|
function = MaxWithBlock
|
|
value = -1 Fails
|
|
value = 0 No score
|
|
value = +1 Verified
|
|
copyAllScoresIfNoCodeChange = true
|
|
----
|
|
|
|
The range of values is:
|
|
|
|
* -1 Fails
|
|
+
|
|
Tried to compile, but got a compile error, or tried to run tests,
|
|
but one or more tests did not pass.
|
|
+
|
|
*Any -1 blocks submit.*
|
|
|
|
* 0 No score
|
|
+
|
|
Didn't try to perform the verification tasks.
|
|
|
|
* +1 Verified
|
|
+
|
|
Compiled (and ran tests) successfully.
|
|
+
|
|
*Any +1 enables submit.*
|
|
|
|
For a change to be submittable, the change must have a `+1 Verified`
|
|
in this label, and no `-1 Fails`. Thus, `-1 Fails` can block a submit,
|
|
while `+1 Verified` enables a submit.
|
|
|
|
Additional values could also be added to this label, to allow it to
|
|
behave more like `Code-Review` (below). Add -2 and +2 entries to the
|
|
`label.Verified.value` fields in `project.config` to get the same
|
|
behavior.
|
|
|
|
|
|
[[label_custom]]
|
|
== Customized Labels
|
|
|
|
Site administrators and project owners can define their own labels,
|
|
or customize labels inherited from parent projects.
|
|
|
|
See above for descriptions of how <<label_Verified,`Verified`>>
|
|
and <<label_Code-Review,`Code-Review`>> work, and add your own
|
|
label to `project.config` to get the same behavior over your own range
|
|
of values, for any label you desire.
|
|
|
|
Just like the built-in labels, users need to be given permissions to
|
|
vote on custom labels. Permissions can either be added by manually
|
|
editing project.config when adding the labels, or, once the labels are
|
|
added, permission categories for those labels will show up in the
|
|
permission editor web UI.
|
|
|
|
Labels may be added to any project's `project.config`; the default
|
|
labels are defined in `All-Projects`.
|
|
|
|
[[label_inheritance]]
|
|
=== Inheritance
|
|
|
|
Labels are inherited from parent projects. A child project may add,
|
|
override, or remove labels defined in its parents.
|
|
|
|
Overriding a label in a child project overrides all its properties and
|
|
values. It is not possible to modify an inherited label by adding
|
|
properties in the child project's configuration; all properties from
|
|
the parent definition must be redefined in the child.
|
|
|
|
To remove a label in a child project, add an empty label with the same
|
|
name as in the parent.
|
|
|
|
[[label_layout]]
|
|
=== Layout
|
|
|
|
Labels are laid out in alphabetical order.
|
|
|
|
[[label_name]]
|
|
=== `label.Label-Name`
|
|
|
|
The name for a label, consisting only of alphanumeric characters and
|
|
`-`.
|
|
|
|
|
|
[[label_value]]
|
|
=== `label.Label-Name.value`
|
|
|
|
A multi-valued key whose values are of the form `"<#> Value description
|
|
text"`. The `<#>` may be any positive or negative number with an
|
|
optional leading `+`.
|
|
|
|
|
|
[[label_defaultValue]]
|
|
=== `label.Label-Name.defaultValue`
|
|
|
|
The default value (or score) for the label. The defaultValue must be
|
|
within the range of valid label values. It is an optional label setting,
|
|
if not defined the defaultValue for the label will be 0. When a
|
|
defaultValue is defined, that value will get set in the Reply dialog
|
|
by default.
|
|
|
|
A defaultValue can be set to a score that is outside of the permissible
|
|
range for a user. In that case the score that will get set in the Reply
|
|
box will be either the lowest or highest score in the permissible range.
|
|
|
|
|
|
[[label_function]]
|
|
=== `label.Label-Name.function`
|
|
|
|
The name of a function for evaluating multiple votes for a label. This
|
|
function is only applied if the default submit rule is used for a label.
|
|
If you write a link:prolog-cookbook.html#HowToWriteSubmitRules[custom
|
|
submit rule] (and do not call the default rule), the function name is
|
|
ignored and may be treated as optional.
|
|
|
|
Valid values are:
|
|
|
|
* `MaxWithBlock` (default)
|
|
+
|
|
The lowest possible negative value, if present, blocks a submit, while
|
|
the highest possible positive value is required to enable submit. There
|
|
must be at least one positive value, or else submit will never be
|
|
enabled. To permit blocking submits, ensure a negative value is defined.
|
|
|
|
* `AnyWithBlock`
|
|
+
|
|
The lowest possible negative value, if present, blocks a submit, Any
|
|
other value enables a submit. To permit blocking submits, ensure
|
|
that a negative value is defined.
|
|
|
|
* `MaxNoBlock`
|
|
+
|
|
The highest possible positive value is required to enable submit, but
|
|
the lowest possible negative value will not block the change.
|
|
|
|
* `NoBlock`/`NoOp`
|
|
+
|
|
The label is purely informational and values are not considered when
|
|
determining whether a change is submittable.
|
|
|
|
* `PatchSetLock`
|
|
+
|
|
The `PatchSetLock` function provides a locking mechanism for patch
|
|
sets. This function's values are not considered when determining
|
|
whether a change is submittable. When set, no new patchsets can be
|
|
created and rebase and abandon are blocked.
|
|
+
|
|
This function is designed to allow overlapping locks, so several lock
|
|
accounts could lock the same change.
|
|
+
|
|
Allowed range of values are 0 (Patch Set Unlocked) to 1 (Patch Set
|
|
Locked).
|
|
|
|
[[label_allowPostSubmit]]
|
|
=== `label.Label-Name.allowPostSubmit`
|
|
|
|
If true, the label may be voted on for changes that have already been
|
|
submitted. If false, the label will not appear in the UI and will not
|
|
be accepted when reviewing a closed change.
|
|
|
|
In either case, voting on a label after submission is only permitted if
|
|
the new vote is at least as high as the old vote by that user. This
|
|
avoids creating the false impression that a post-submit vote can change
|
|
the past and affect submission somehow.
|
|
|
|
Defaults to true.
|
|
|
|
[[label_copyMinScore]]
|
|
=== `label.Label-Name.copyMinScore`
|
|
|
|
If true, the lowest possible negative value for the label is copied
|
|
forward when a new patch set is uploaded. Defaults to false, except
|
|
for All-Projects which has it true by default.
|
|
|
|
[[label_copyMaxScore]]
|
|
=== `label.Label-Name.copyMaxScore`
|
|
|
|
If true, the highest possible positive value for the label is copied
|
|
forward when a new patch set is uploaded. This can be used to enable
|
|
sticky approvals, reducing turn-around for trivial cleanups prior to
|
|
submitting a change. Defaults to false.
|
|
|
|
[[label_copyAllScoresOnMergeCommitFirstParentUpdate]]
|
|
=== `label.Label-Name.copyAllScoresOnMergeCommitFirstParentUpdate`
|
|
|
|
This policy is useful if you don't want to trigger CI or human
|
|
verification again if your target branch moved on but the feature
|
|
branch being merged into the target branch did not change. It only
|
|
applies if the patch set is a merge commit.
|
|
|
|
If true, all scores for the label are copied forward when a new
|
|
patch set is uploaded that is a new merge commit which only
|
|
differs from the previous patch set in its first parent, or has
|
|
identical parents. The first parent would be the parent of the merge
|
|
commit that is part of the change's target branch, whereas the other
|
|
parent(s) refer to the feature branch(es) to be merged.
|
|
|
|
Defaults to false.
|
|
|
|
[[label_copyAllScoresOnTrivialRebase]]
|
|
=== `label.Label-Name.copyAllScoresOnTrivialRebase`
|
|
|
|
If true, all scores for the label are copied forward when a new patch
|
|
set is uploaded that is a trivial rebase. A new patch set is considered
|
|
as trivial rebase if the commit message is the same as in the previous
|
|
patch set and if it has the same code delta as the previous patch set.
|
|
This is the case if the change was rebased onto a different parent, or
|
|
if the parent did not change at all.
|
|
|
|
This can be used to enable sticky approvals, reducing turn-around for
|
|
trivial rebases prior to submitting a change.
|
|
For the pre-installed Code-Review label this is enabled by default.
|
|
|
|
Defaults to false.
|
|
|
|
[[label_copyAllScoresIfNoCodeChange]]
|
|
=== `label.Label-Name.copyAllScoresIfNoCodeChange`
|
|
|
|
If true, all scores for the label are copied forward when a new patch
|
|
set is uploaded that has the same parent tree as the previous patch
|
|
set and the same code delta as the previous patch set. This means only
|
|
the commit message is different. This can be used to enable sticky
|
|
approvals on labels that only depend on the code, reducing turn-around
|
|
if only the commit message is changed prior to submitting a change.
|
|
For the Verified label that is optionally installed by the
|
|
link:pgm-init.html[init] site program this is enabled by default.
|
|
|
|
Defaults to false.
|
|
|
|
[[label_copyAllScoresIfNoChange]]
|
|
=== `label.Label-Name.copyAllScoresIfNoChange`
|
|
|
|
If true, all scores for the label are copied forward when a new patch
|
|
set is uploaded that has the same parent tree, code delta, and commit
|
|
message as the previous patch set. This means that only the patch
|
|
set SHA1 is different. This can be used to enable sticky
|
|
approvals, reducing turn-around for this special case.
|
|
It is recommended to leave this enabled for both Verified and
|
|
Code-Review labels.
|
|
|
|
Defaults to true.
|
|
|
|
[[label_canOverride]]
|
|
=== `label.Label-Name.canOverride`
|
|
|
|
If false, the label cannot be overridden by child projects. Any
|
|
configuration for this label in child projects will be ignored. Defaults
|
|
to true.
|
|
|
|
[[label_branch]]
|
|
=== `label.Label-Name.branch`
|
|
|
|
By default a given project's label applicable scope is all changes
|
|
on all branches of this project and its child projects.
|
|
|
|
Label's applicable scope can be branch specific via configuration.
|
|
E.g. create a label `Video-Qualify` on parent project and configure
|
|
the `branch` as:
|
|
|
|
----
|
|
[label "Video-Qualify"]
|
|
branch = refs/heads/video-1.0/*
|
|
branch = refs/heads/video-1.1/Kino
|
|
----
|
|
|
|
Then *only* changes in above branch scope of parent project and child
|
|
projects will be affected by `Video-Qualify`.
|
|
|
|
[NOTE]
|
|
The `branch` is independent from the branch scope defined in `access`
|
|
parts in `project.config` file. That means from the UI a user can always
|
|
assign permissions for that label on a branch, but this permission is then
|
|
ignored if the label doesn't apply for that branch.
|
|
Additionally, the `branch` modifier has no effect when the submit rule
|
|
is customized in the rules.pl of the project or inherited from parent projects.
|
|
|
|
[[label_example]]
|
|
=== Example
|
|
|
|
To define a new 3-valued category that behaves exactly like `Verified`,
|
|
but has different names/labels:
|
|
|
|
----
|
|
[label "Copyright-Check"]
|
|
function = MaxWithBlock
|
|
value = -1 Do not have copyright
|
|
value = 0 No score
|
|
value = +1 Copyright clear
|
|
----
|
|
|
|
The new column will appear at the end of the table, and `-1 Do not have
|
|
copyright` will block submit, while `+1 Copyright clear` is required to
|
|
enable submit.
|
|
|
|
=== Default Value Example
|
|
|
|
This example attempts to describe how a label default value works with the
|
|
user permissions. Assume the configuration below.
|
|
|
|
----
|
|
[access "refs/heads/*"]
|
|
label-Snarky-Review = -3..+3 group Administrators
|
|
label-Snarky-Review = -2..+2 group Project Owners
|
|
label-Snarky-Review = -1..+1 group Registered Users
|
|
[label "Snarky-Review"]
|
|
value = -3 Ohh, hell no!
|
|
value = -2 Hmm, I'm not a fan
|
|
value = -1 I'm not sure I like this
|
|
value = 0 No score
|
|
value = +1 I like, but need another to like it as well
|
|
value = +2 Hmm, this is pretty nice
|
|
value = +3 Ohh, hell yes!
|
|
defaultValue = -3
|
|
----
|
|
|
|
Upon clicking the Reply button:
|
|
|
|
* Administrators have all scores (-3..+3) available, -3 is set as the default.
|
|
* Project Owners have limited scores (-2..+2) available, -2 is set as the default.
|
|
* Registered Users have limited scores (-1..+1) available, -1 is set as the default.
|
|
|
|
=== Patch Set Lock Example
|
|
|
|
This example shows how a label can be configured to have a standard patch set lock.
|
|
|
|
----
|
|
[access "refs/heads/*"]
|
|
label-Patch-Set-Lock = +0..+1 group Administrators
|
|
[label "Patch-Set-Lock"]
|
|
function = PatchSetLock
|
|
value = 0 Patch Set Unlocked
|
|
value = +1 Patch Set Locked
|
|
defaultValue = 0
