= Review UI
Reviewing changes is an important task and the Gerrit Web UI provides
many functionalities to make the review process comfortable and
efficient.
The UI has three different main views,
** The dashboard, which shows all changes that are relevant to you
** The change screen, which shows the change with all its metadata
** The diff view, which shows changes to a single file
[[change-screen]]
== Change Screen
The change screen shows the details of a single change and provides
various actions on it.
image::images/user-review-ui-change-screen.png[width=800, link="images/user-review-ui-change-screen.png"]
Here are the main areas of the screen
image::images/user-review-ui-change-screen-annotated.png[width=800, link="images/user-review-ui-change-screen-annotated.png"]
=== Top info
Top left, you find the status of the change, and a permalink.
image::images/user-review-ui-change-screen-topleft.png[width=400, link="images/user-review-ui-change-screen-topleft.png"]
[[change-status]]
The change status shows the state of the change:
- [[active]]`Active`:
+
The change is under active review.
- [[merge-conflict]]`Merge Conflict`:
+
The change can't be merged due to conflicts.
- [[ready-to-submit]]`Ready to Submit`:
+
The change has all necessary approvals and may be submitted.
- [[merged]]`Merged`:
+
The change was successfully merged into the destination branch.
- [[abandoned]]`Abandoned`:
+
The change was abandoned.
[[star]]
=== Star Change
Clicking the star icon marks the change as a favorite: it turns on
email notifications for this change, and the change is added to the
list under `Your` > `Starred Changes`. They can be queried by the
link:user-search.html#is[is:starred] search operator.
[[change-info]]
=== Change metadata
The change metadata block contains detailed information about the change
and offers actions on the change.
- [[reviewers]]Reviewers:
+
The reviewers of the change are displayed as chips.
+
For each reviewer there is a tooltip that shows on which labels the
reviewer is allowed to vote.
+
New reviewers can be added by clicking on the pencil icon. Typing
into the pop-up text field activates auto completion of user and group
names.
+
[[remove-reviewer]]
Reviewers can be removed from the change by clicking on the `x` icon
in the reviewer's chip token. Removing a reviewer also removes the
current votes of the reviewer. The removal of votes is recorded as a
message on the change.
+
Removing reviewers is protected by permissions:
** Users can always remove themselves.
** The change owner may remove any zero or positive score.
** Users with the link:access-control.html#category_remove_reviewer[
Remove Reviewer] access right, the branch owner, the project owner
and Gerrit administrators may remove anyone.
+
image::images/user-review-ui-change-screen-info-reviewers.png[width=600, link="images/user-review-ui-change-screen-reviewers.png"]
- [[project-branch-topic]]Project / Branch / Topic:
+
The name of the project for which the change was done is displayed as a
link to the link:user-dashboards.html#project-default-dashboard[default
dashboard] of the project. If no default dashboard is defined, the link
opens a list of open changes on the project.
+
The name of the destination branch is displayed as a link to a list
with all changes on this branch that have the same status as the
currently viewed change.
+
If a topic was assigned to the change it is displayed below the branch.
By clicking on the edit icon the topic can be set. This requires the
link:access-control.html#category_edit_topic_name[Edit Topic Name]
access right. To be able to set a topic on a closed change, the
`Edit Topic Name` must be assigned with the `force` flag.
- [[submit-strategy]]Submit Strategy:
+
The link:project-setup.html#submit_type[submit strategy] that will be
used to submit the change. The submit strategy is only displayed for
open changes.
- [[actions]]Actions:
+
Actions buttons are at the top, and in the overflow menu.
Depending on the change state and the permissions of the user, different
actions are available on the change:
** [[submit]]`Submit`:
+
Submits the change and adds it to the merge queue. If possible the
change is merged into the destination branch.
+
The `Submit` button is available if the change is submittable and
the link:access-control.html#category_submit[Submit] access right is
assigned.
** [[revert]]`Revert`:
+
Reverts the change via creating a new one.
+
The `Revert` button is available if the change has been submitted.
+
When the `Revert` button is pressed, a panel will appear to allow
the user to enter a commit message for the reverting change.
+
Once a revert change is created, the original author and any reviewers
of the original change are added as reviewers and a message is posted
to the original change linking to the revert.
** [[abandon]]`Abandon`:
+
Abandons the change.
+
The `Abandon` button is only available if the change is open and the
link:access-control.html#category_abandon[Abandon] access right is
assigned.
+
When a change is abandoned, a panel appears that allows one to type a
comment message to explain why the change is being abandoned.
** [[restore]]`Restore`:
+
Restores the change.
+
The `Restore` button is only available if the change is abandoned and
the link:access-control.html#category_abandon[Abandon] and the
link:access-control.html#category_push[Push] access right is
assigned.
+
When a change is restored, a panel appears that allows one to type a
comment message to explain why the change is being restored.
** [[rebase]]`Rebase`:
+
Rebases the change. The rebase is always done with content merge
enabled. If the rebase is successful a new patch set with the rebased
commit is created. If the rebase fails, there are conflicts that have
to be resolved manually.
+
If the change does not depend on another open change, it is rebased
onto the tip of the destination branch.
+
If the change depends on another open change, it is rebased onto the
current patch set of that other change.
+
It is possible to change parent revision of a change. The new parent
revision can be another change towards the same target branch, or
the tip of the target branch.
+
The `Rebase` button is only available if
the link:access-control.html#category_rebase[Rebase] access right is
assigned. Rebasing merge commits is not supported.
** [[cherry-pick]]`Cherry-Pick`:
+
Allows to cherry-pick the change to another branch. The destination
branch can be selected from a dialog. Cherry-picking a change creates a
new open change on the selected destination branch.
+
It is also possible to cherry-pick a change to the same branch. This is
effectively the same as rebasing it to the current tip of the
destination branch. This can be used to remove dependencies on other
open changes.
+
Users can only cherry-pick changes to branches for which they are
allowed to upload changes for review.
** [[delete]]`Delete Change` / `Delete Revision`:
+
Deletes the change.
+
For open or abandoned changes, the `Delete Change` button will be available
and if the user is the change owner and is granted the
link:access-control.html#category_delete_own_changes[Delete Own Changes]
permission, if they are granted the
link:access-control.html#category_delete_changes[Delete Changes] permission,
or if they are an administrator.
** [[plugin-actions]]Further actions may be available if plugins are installed.
+
image::images/user-review-ui-change-screen-change-info-actions.png[width=600, link="images/user-review-ui-change-screen-change-info-actions.png"]
- [[labels]]Labels & Votes:
+
Approving votes are colored green; negative votes are colored red.
+
image::images/user-review-ui-change-screen-change-info-labels.png[width=400, link="images/user-review-ui-change-screen-change-info-labels.png"]
[[files]]
=== File List
The file list shows the files that are modified in the currently viewed
patch set.
image::images/user-review-ui-change-screen-file-list.png[width=800, link="images/user-review-ui-change-screen-file-list.png"]
[[magic-files]]
In addition to the modified files the file list contains magic files
that are generated by Gerrit and which don't exist in the repository.
The magic files contain additional commit data that should be
reviewable and allow users to comment on this data. The magic files are
always listed first. The following magic files exist:
* `Commit Message`:
+
The commit message and headers with the parent commit(s), the author
information and the committer information.
* `Merge List` (for merge commits only):
+
The list of commits that are being integrated into the destination
branch by submitting the merge commit.
[[patch-sets]]
=== Patch Sets
The change screen only presents one patch set at a time. Which patch
set is currently viewed can be seen from the `Patch Sets` drop-down
panel in the change header.
image::images/user-review-ui-change-screen-patch-sets.png[width=487, link="images/user-review-ui-change-screen-patch-sets.png"]
[[download]]
=== Download
The `Download` drop-down panel in the change header offers commands and
links for downloading the currently viewed patch set.
image::images/user-review-ui-change-screen-download-commands.png[width=800, link="images/user-review-ui-change-screen-download-commands.png"]
The available download commands depend on the installed Gerrit plugins.
The most popular plugin for download commands, the
link:https://gerrit-review.googlesource.com/admin/repos/plugins/download-commands[
download-commands,role=external,window=_blank] plugin, provides commands to checkout, pull and
cherry-pick a patch set.
Each command has a copy-to-clipboard icon that allows the command to be
copied into the clipboard. This makes it easy to paste and execute the
command on a Git command line.
If several download schemes are configured on the server (e.g. SSH and
HTTP) there is a drop-down list to switch between the download schemes.
Gerrit automatically remembers the download scheme that was last chosen
and selects this download scheme the next time the download commands
drop-down panel is opened.
The `Patch-File` links provide the Git patch file for the currently
viewed patch set for download. The patch file can be base64 encoded or
zipped.
The `Archive` links allow one to download an archive with the contents
of the currently viewed patch set. The archive is offered in several
formats (e.g. tar and tbz2); which formats are available depends on the
configuration of the server.
[[included-in]]
=== Included In
For merged changes the `Included In` drop-down panel is available
through the overflow menu at the top. It shows the branches and tags
in which the change is included. E.g. if a change fixes a bug, this
shows which released versions contain the bug-fix (assuming that every
release is tagged).
image::images/user-review-ui-change-screen-included-in.png[width=800, link="images/user-review-ui-change-screen-included-in.png"]
[[related-changes]]
=== Related Changes
If there are changes that are related to the currently viewed change
they are displayed in the third column of the change screen.
There are several lists of related changes and a tab control is used to
display each list of related changes in its own tab.
The following tabs may be displayed:
- [[related-changes-tab]]`Related Changes`:
+
This tab page shows changes on which the current change depends
(ancestors) and open changes that depend on the current change
(descendants). For merge commits it also shows the closed changes that
will be merged into the destination branch by submitting the merge
commit.
+
The changes are sorted in the same way as the output of 'git log'. This
means the relationship between the changes can be inferred from the
position of the changes in the list. Changes listed above the current
change are descendants; changes below the current change are ancestors.
+
For merged changes this tab is only shown if there are open
descendants.
+
Related changes may be annotated with dependencies
on outdated patch sets, or commits that are not associated to changes
under review:
+
** [[not-current]]Not current:
+
The selected patch set of the change is outdated; it is not the current
patch set of the change.
+
It means that the
currently viewed patch set depends on a outdated patch set of the
ancestor change. This is because a new patch set for the ancestor
change was uploaded in the meantime and as result the currently viewed
patch set now needs to be rebased.
+
If a descendant change is marked "not current" it means that an
old patch set of the descendant change depends on the currently viewed
patch set. It may be that the descendant was rebased in the meantime
and with the new patch set this dependency was removed.
** [[indirect-descendant]]Indirect descendant:
+
The selected patch set of the change is an indirect descendant of the
currently viewed patch set; it has a dependency to another patch set of
this change. E.g. this could mean that a new patch set was uploaded for
this change and the descendant change now needs to be rebased. Please
note that following the link to an indirect descendant change may
result in a completely different related changes listing.
** [[closed-ancestor]]Closed ancestor:
+
Indicates a closed ancestor, e.g. the commit was directly pushed into
the repository bypassing code review, or the ancestor change was
reviewed and submitted on another branch. The latter may indicate that
the user has accidentally pushed the commit to the wrong branch, e.g.
the commit was done on `branch-a`, but was then pushed to
`refs/for/branch-b`.
** [[closed-ancestor-abandoned]]Abandoned:
+
Indicates an abandoned change.
- [[conflicts-with]]`Conflicts With`:
+
This section shows changes that conflict with the current change.
Non-mergeable changes are filtered out; only conflicting changes that
are mergeable are shown.
+
If this change is merged, its conflicting changes will have merge
conflicts and must be rebased. The rebase of the other changes with the
conflict resolution must then be done manually.
- [[submitted-together]]`Submitted Together`:
+
This section shows changes that will be submitted together with the
currently viewed change, when clicking the submit button. It includes
ancestors of the current patch set.
+
This may include changes and its ancestors with the same topic if
`change.submitWholeTopic` is enabled. Only open changes with the
same topic are included in the list.
+
- [[cherry-picks]]`Cherry-Picks`:
+
This section shows changes with the same link:user-changeid.html[
Change-Id] for the current project.
+
Abandoned changes are filtered out.
+
For each change in this list the destination branch is shown as a
prefix in front of the change subject.
+
If there are no related changes for a tab, the tab is not displayed.
[[reply]]
=== Reply
The `Reply...` button in the change header allows to reply to the
currently viewed patch set; one can add a summary comment, publish
inline draft comments, and vote on the labels.
image::images/gwt-user-review-ui-change-screen-reply.png[width=800, link="images/gwt-user-review-ui-change-screen-reply.png"]
Clicking on the `Reply...` button opens a popup panel.
[[summary-comment]]
A text box allows to type a summary comment for the currently viewed
patch set. Some basic markdown-like syntax is supported which renders
indented lines preformatted, lines starting with "- " or "* " as list
items, and lines starting with "> " as block quotes (also see replying to
link:#reply-to-message[messages] and link:#reply-inline-comment[inline comments]).
Note that you can set the text and tooltip of the button in
link:config-gerrit.html#change.replyLabel[gerrit.config].
[[vote]]
If the current patch set is viewed, radio buttons are displayed for
each label on which the user is allowed to vote. Voting on non-current
patch sets is not possible.
The inline draft comments that will be published are displayed in a
separate section so that they can be reviewed before publishing. There
are links to navigate to the inline comments which can be used if a
comment needs to be edited.
The `Post` button publishes the comments and the votes.
image::images/gwt-user-review-ui-change-screen-replying.png[width=800, link="images/gwt-user-review-ui-change-screen-replying.png"]
[[quick-approve]]
If a user can approve a label that is still required, a quick approve
button appears in the change header that allows to add this missing
approval by a single click. The quick approve button only appears if
there is a single label that is still required and can be approved by
the user.
E.g. if a change requires approvals on the 'Code-Review' and the
'Verified' labels, and there is already a '+1 Verified' vote, then
if the user is allowed to vote the max score on 'Code-Review', a
`Code-Review+2` quick approve button appears that approves the
'Code-Review' label if clicked.
Using the quick approve button also publishes all inline draft
comments; a summary comment is only added if the reply popup panel is
open when the quick approve button is clicked.
image::images/user-review-ui-change-screen-quick-approve.png[width=800, link="images/gwt-user-review-ui-change-screen-quick-approve.png"]
[[history]]
=== History
The history of the change can be seen in the lower part of the screen.
The history contains messages for all kinds of change updates, e.g. a
message is added when a new patch set is uploaded or when a review was
done.
Messages with new comments from other users, that were published after
the current user last reviewed this change, are automatically expanded.
image::images/gwt-user-review-ui-change-screen-history.png[width=800, link="images/gwt-user-review-ui-change-screen-history.png"]
[[reply-to-message]]
It is possible to directly reply to a change message by clicking on the
reply icon in the right upper corner of a change message. This opens
the reply popup panel and prefills the text box with the quoted comment.
Then the reply can be written below the quoted comment or inserted
inline. Lines starting with "> " will be rendered as a block quote.
Please note that for a correct rendering it is important to leave a blank
line between a quoted block and the reply to it.
image::images/gwt-user-review-ui-change-screen-reply-to-comment.png[width=800, link="images/gwt-user-review-ui-change-screen-reply-to-comment.png"]
[[inline-comments-in-history]]
Inline comments are directly displayed in the change history and there
are links to navigate to the inline comments.
image::images/gwt-user-review-ui-change-screen-inline-comments.png[width=800, link="images/gwt-user-review-ui-change-screen-inline-comments.png"]
[[expand-all]]
The `Expand All` button expands all messages; the `Collapse All` button
collapses all messages.
[[update-notification]]
=== Update Notification
The change screen automatically polls for updates to the currently
viewed change. If there is an update the user is informed by a popup
panel in the bottom right corner.
The polling frequency depends on the server configuration; by default
it is 30 seconds. Polling may also be completely disabled by the
administrator.
image::images/gwt-user-review-ui-change-screen-change-update.png[width=800, link="images/gwt-user-review-ui-change-screen-change-update.png"]
[[plugin-extensions]]
=== Plugin Extensions
Gerrit plugins may extend the change screen; they can add buttons for
additional actions to the change info block and display arbitrary UI
controls below the change info block.
image::images/gwt-user-review-ui-change-screen-plugin-extensions.png[width=800, link="images/gwt-user-review-ui-change-screen-plugin-extensions.png"]
[[side-by-side]]
== Side-by-Side Diff Screen
The side-by-side diff screen shows a single patch; the old file version
is displayed on the left side of the screen; the new file version is
displayed on the right side of the screen.
This screen allows to review a patch and to comment on it.
image::images/gwt-user-review-ui-side-by-side-diff-screen.png[width=800, link="images/gwt-user-review-ui-side-by-side-diff-screen.png"]
[[side-by-side-header]]
In the screen header the project name and the name of the viewed patch
file are shown.
If a Git web browser is configured on the server, the project name and
the file path are displayed as links to the project and the folder in
the Git web browser.
image::images/gwt-user-review-ui-side-by-side-diff-screen-project-and-file.png[width=800, link="images/gwt-user-review-ui-side-by-side-diff-screen-project-and-file.png"]
[[side-by-side-mark-reviewed]]
The checkbox in front of the file name allows the
patch to be marked as reviewed. The link:#mark-reviewed[Mark Reviewed]
diff preference allows to control whether the files should be
automatically marked as reviewed when they are viewed.
image::images/user-review-ui-side-by-side-diff-screen-reviewed.png[width=800, link="images/gwt-user-review-ui-side-by-side-diff-screen-reviewed.png"]
[[patch-set-selection]]
In the header, on each side, the list of patch sets is shown. Clicking
on a patch set changes the selection for the patch set comparison and
the screen is refreshed to show the diff between the selected patch
sets. The currently selected patch set is highlighted by a light blue
background.
On the left side `Base` can be selected to compare a patch set against
its base. For merge commits `Auto Merge` is available instead which
allows to compare the patch against the result of the auto merge. The
auto merge version may contain Git conflict markers and is useful for
reviewing how conflicts are resolved by a patch.
Reviewers that are reviewing a patch for the first time look at its
diff against its base; reviewers that have reviewed an old patch
version before, may see what has changed since that version by
comparing the old patch against the current patch.
image::images/gwt-user-review-ui-side-by-side-diff-screen-patch-sets.png[width=800, link="images/gwt-user-review-ui-side-by-side-diff-screen-patch-sets.png"]
[[download-file]]
The download icon next to the patch set list allows to download the
patch. Unless the mime type of the file is configured as safe, the
download file is a zip archive that contains the patch file.
[[no-differences]]
If the compared patches are identical, this is highlighted by a red
`No Differences` label in the screen header.
image::images/gwt-user-review-ui-side-by-side-diff-screen-no-differences.png[width=800, link="images/gwt-user-review-ui-side-by-side-diff-screen-no-differences.png"]
[[side-by-side-rename]]
If a file was renamed, the old and new file paths are shown in the
header together with a similarity index that shows how much of the file
content is unmodified.
image::images/gwt-user-review-ui-side-by-side-diff-screen-rename.png[width=800, link="images/gwt-user-review-ui-side-by-side-diff-screen-rename.png"]
[[navigation]]
For navigating between the patches in a patch set there are navigation
buttons on the right side of the screen header. The left arrow button
navigates to the previous patch; the right arrow button navigates to
the next patch. The arrow up button leads back to the change screen. In
all cases the selection for the patch set comparison is kept.
image::images/gwt-user-review-ui-side-by-side-diff-screen-navigation.png[width=800, link="images/gwt-user-review-ui-side-by-side-diff-screen-navigation.png"]
[[inline-comments]]
=== Inline Comments
Inline comments are displayed directly in the patch file under the code
that is commented. Inline comments can be placed on lines or on code
blocks.
If an inline comment relates to a code block, this code block is
highlighted by a yellow background.
Code blocks with comments may overlap. This means it is possible to
attach several comments to the same code.
[[line-links]]
The lines of the patch file are linkable. To link to a certain line in
the patch file, '@<line-number>' must be appended to the patch link,
e.g. `http://host:8080/#/c/56857/2/Documentation/user-review-ui.txt@665`.
To link to a line in the old file version, '@a<line-number>' must be
appended to the patch link. These links can be used to directly link to
certain inline comments.
If the diff preference link:#expand-all-comments[Expand All Comments]
is set to `Expand`, all inline comments will be automatically expanded.
image::images/gwt-user-review-ui-side-by-side-diff-screen-inline-comments.png[width=800, link="images/gwt-user-review-ui-side-by-side-diff-screen-inline-comments.png"]
[[comment]]
In the header of the comment box, the name of the comment author and
the timestamp of the comment are shown. If avatars are configured on
the server, the avatar image of the comment author is displayed in the
top left corner. Below the actual comment there are buttons to reply to
the comment.
image::images/gwt-user-review-ui-side-by-side-diff-screen-comment-box.png[width=800, link="images/gwt-user-review-ui-side-by-side-diff-screen-comment-box.png"]
[[reply-inline-comment]]
Clicking on the `Reply` button opens an editor to type the reply.
Quoting is supported, but only by manually copying & pasting the old
comment that should be quoted and prefixing every line by "> ". Please
note that for a correct rendering it is important to leave a blank line
between a quoted block and the reply to it.
Clicking on the `Save` button saves the comment as a draft. To make it
visible to other users it must be published from the change screen by
link:#reply[replying] to the change.
The `Cancel` button cancels the editing and discards any changes to the
draft comment.
Clicking on the `Discard` button deletes the inline draft comment.
image::images/gwt-user-review-ui-side-by-side-diff-screen-comment-reply.png[width=800, link="images/gwt-user-review-ui-side-by-side-diff-screen-comment-reply.png"]
[[draft-inline-comment]]
Draft comments are marked by the text "Draft" in the header in the
place of the comment author.
A draft comment can be edited by clicking on the `Edit` button, or
deleted by clicking on the `Discard` button.
image::images/gwt-user-review-ui-side-by-side-diff-screen-comment-edit.png[width=800, link="images/gwt-user-review-ui-side-by-side-diff-screen-comment-edit.png"]
[[done]]
Clicking on the `Done` button is a quick way to reply with "Done" to a
comment. This is used to mark a comment as addressed by a follow-up
patch set.
image::images/gwt-user-review-ui-side-by-side-diff-screen-replied-done.png[width=800, link="images/gwt-user-review-ui-side-by-side-diff-screen-replied-done.png"]
[[add-inline-comment]]
To add a new inline comment there are several possibilities:
- select a code block and press 'c'
- select a code block and click on the popup comment icon
- go to a line, by clicking on it or by link:#key-navigation[key
navigation], and press 'c'
- click on a line number
There are many ways to select code for commenting on it. The most
frequently used methods are:
- by mouse:
** click and drag with the mouse to select a block
** double-click on a word to select it
** double-click and drag with the mouse to select a code block word-wise
** triple-click on a line to select it
** triple-click and drag with the mouse to select a code block line-wise
- by keys (the same keys that are used for visual selection in Vim):
** press 'v' + arrow keys (or 'h', 'j', 'k', 'l') to select a block
** press 'V' + arrow keys (or 'j', 'k') to select a code block line-wise
** type 'bvw' to select a word
image::images/gwt-user-review-ui-side-by-side-diff-screen-comment.png[width=800, link="images/gwt-user-review-ui-side-by-side-diff-screen-comment.png"]
For typing the new comment, a new comment box is shown under the code
that is commented.
Clicking on the `Save` button saves the new comment as a draft. To make
it visible to other users it must be published from the change screen
by link:#reply[replying] to the change.
Clicking on the `Discard` button deletes the new comment.
image::images/gwt-user-review-ui-side-by-side-diff-screen-commented.png[width=800, link="images/gwt-user-review-ui-side-by-side-diff-screen-commented.png"]
[[file-level-comments]]
=== File Level Comments
File level comments are added by clicking the 'File' header at the top
of the file.
image::images/user-review-ui-side-by-side-diff-screen-file-level-comment.png[width=800, link="images/gwt-user-review-ui-side-by-side-diff-screen-file-level-comment.png"]
[[diff-preferences]]
=== Diff Preferences
There are several options to control how patch diffs should be
rendered. Users can configure their preferences in the diff
preferences. The diff preferences can be accessed by clicking on the
settings icon in the screen header.
image::images/user-review-ui-side-by-side-diff-screen-preferences.png[width=800, link="images/gwt-user-review-ui-side-by-side-diff-screen-preferences.png"]
The following diff preferences can be configured:
- [[ignore-whitespace]]`Ignore Whitespace`:
+
Controls whether differences in whitespace should be ignored or not.
+
** `None`:
+
All differences in whitespace are highlighted.
+
