Review for Eclipse (R4E) is a set of Eclipse plugins that provide eclipse-integrated code and text review functionality. R4E supports reviewing files associated to Eclipse projects and optionally included under a Version Control System. Three review workflows are included (Basic, Informal and IEEE standard 1028-compatible Formal reviews).
The main purpose of R4E is to review Source Code, especially Java and C/C++ Source code. Eventually, support for reviewing Data Models (based on EMF) will be included. R4E also aims to support multiple Version Control Systems (via Eclipse Team Providers). Git (implemented in Eclipse through EGit/JGit), and SVN (implemented in Eclipse through Subclipse) are the ones currently supported.
The R4E User Interface includes three main components: R4E Review Navigator View, R4E Properties View and R4E Context Menus
The R4E Review Navigator View is the main interface to R4E. It shows all the R4E elements in a hierarchical tree structure The R4E Properties view, using the generic Eclipse Properties View, presents the properties and attributes attached to each R4E element represented in the Review Navigator view. Some elements values can be altered after creation, and some other or read-only and settable at creation time. The R4E Context Menu appears in Eclipse Context menus whenever it is possible to use R4E command is this particular context. Please refer to [section] below for more information.
R4E main interfaces
R4E interacts with the follwing features/plugins:
- Mylyn Versions Connectors for Egit and Svn (via Subclipse)
- C/C++ Language support: CDT (Optional)
- Java Language support: JDT (Optional)
- LDAP Connector: R4E LDAP plugin
- Email support: R4E SMTP connector
- Meeting support: R4E VCalendar connector
- General: EMF (for the Review meta-data)
Provision Software Sites
Installation using Bleeding Edge Nightly Builds (use with Eclipse 3.7, Indigo)
Add the following Software Sites to the Eclipse workspace (Help -> Install New Software -> Add)
Mylyn weekly: http://download.eclipse.org/mylyn/snapshots/weekly
Mylyn Versions nightly: http://download.eclipse.org/mylyn/snapshots/nightly/versions/
Mylyn Reviews nightly: http://download.eclipse.org/mylyn/snapshots/nightly/reviews/
if Subversion is to be used, add the subclipse site: http://subclipse.tigris.org/update_1.6.x
Install Version Control System Features
R4E uses Mylyn Versions to interact with different version control systems.
- Git support is provided by interfacing with Egit/Jgit,
- Installing the R4E feature automatically installs Egit/Jgit if it's not yet available in the Eclipse installation.
- So no specific action is needed for Egit installation in this step.
- Subversion (SVN)
- If there is a need to interact with an SVN repository, install the subclipse feature.
- Help -> Install New Software, and select the subclipse site provisioned above.
Install R4E feature
Help -> Install New Software, and select the Mylyn Reviews site provisioned above.
Install Versions Connectors
Help -> Install New Software, and select the Mylyn Versions site provisioned above.
Select the connector(s) needed to interface your version control system(s).
currently, R4E supports Git and Subclipse connectors.
To start up R4E, show the Review Navigator View e.g. using the Eclipse Window->Show View menu:
The R4E Configuration can be entered by accessing the R4E Preferences Pages, which are part of the Eclipse Global Preferences. There are three R4E Preference Pages: R4E General Preferences, R4E LDAP Settings, and SMTP Hosts Definitions.
R4E General Preferences
R4E General Preferences page is split up into four tab sections. Take note that the Restore Defaults and Apply buttons apply to the values displayed in all the tabs
- User Tab
This is used to enter the current user details. The User ID is set by default to the login ID of the current session and can be modified to any String that can be used to identify the user. The User Email should be set to a valid email for the user. The E-mail address is used to notify the user informations about the reviews he is currently part of by Email, as configured in the SMTP Hosts Definitions section. Take note that if the LDAP Preferences are filled-in (see below) and a corresponding LDAP database can be resolved, then this field will be automatically be set based on the User ID entered. The Create Delta Elements... check box is used to control the display of file differences as elements in the Review Navigator. The Update Postponed Anomalies... is used to automatically import outstanding anomalies that were set to postponed in previous versions of files included in the current review. See Postponed Anomalies section below for more information.
- Groups Tab
This is used to specify the location of the data files that contain Review Group information. See below for more information on Review Groups. The Name and Description fields show additional information attached to the selected Review Group file. Typically, all R4E data files will be located on a shared network drive. Users can add one or multiple references to Group files to their workspace as needed using the Add button. Files can be removed from the workspace by pressing the Remove button. Files can be moved up or down in the list by clicking the corresponding button. This will affect the order in which the Groups are displayed in the Review Navigator.
Note: Make sure the defined directory location is accessible and configured with read/write permissions for the team members involved in the review.
- Rule Sets Tab
This is used to specify the location of the data files that contain Rule Set information. See below for more information on Rule Sets. The Name and Version fields show additional information attached to the selected Rule Set file. Typically, all R4E data files will be located on a shared network drive. Users can add one or multiple referecnes to Rule Set files to their workspace as needed using the Add button. Files can be removed from the workspace by pressing the Remove button. Files can be moved up or down in the list by clicking the corresponding button. This will affect the order in which the Rule Sets are displayed in the Review Navigator.
- Filter Tabs
This is used to set-up default filters that will be applied to the Review Navigator view. See the Filters section below for the various filters descriptions.
R4E LDAP Settings
This is used the specify configuration for an available LDAP database server that contains information about the users. The Server Information part contains LDAP server information (Host, Port, DN (Distinguished Name), and Login User Name and Password) to use. The Mandatory Parameters part contains mapping values for LDAP attributes that maps the User Id, Name and E-Mail parameters The Optional Parameters part contains mapping values for LDAP attributes that maps optional parameters that could exists in the database.
This is optional. If no information is entered, LDAP functionality will be unavailable, but will not affect R4E otherwise
SMTP Hosts Definitions
This is used to specify the mail server(s) that will be used to send manual and automatic email notifications to the users. More than one server can be specified. Users can add one or multiple servers to their workspace as needed using the Add button. Servers can be removed from the workspace by pressing the Remove button. Servers can be moved up or down in the list by clicking the corresponding button. The primary server should always be the first on the list.
R4E uses Eclipse Capabilities to manage its functionalities. In order to use R4E, its capabilities must be enabled. This can be done by enabling R4E in the Eclipse Preferences->General->Capabilities preference page.
Eclipse Project Configuration
- R4E can be used to create reviews that include files present in given Eclipse Projects.
- While R4E can operate on stand-alone Eclipse projects (i.e. outside of any Version Control System), it is recommended that it is used in conjuction with projects that are held within Revision Control. Currently, R4E supports Version-Controlled projects that are associated with Egit and Subclipse as team provider., For Git, the "EGit/User Guide" is the best place to find the information on how to create new repositories, work with existing repositories and importing Eclipse projects under and existing repositories into the Eclipse workspace.
- Once the project is associated/connected to the team provider the project will display the project name and associated branch between brackets.
To familiarize yourself with how R4E operates, three tutorials are provided, which focus on the different review types and their respective workflows. As we progress in doing the tutorials, more common functionalities are introduced (such as Notifications, Meeting Requests, Setting reviewed state, Disabling elements etc.).
Configuration and Set-up
Before doing any of the tutorials, we will set-up R4E and configure it to do reviews.
- Open the R4E Review Navigator view by going to the Window->Show View->Other... dialog.
- Select the R4E->Review Navigator view. An empty Review Navigator view should now be visible
- Typically, users will use Review Groups and (optionally) Rule Sets already created. For now we will assume none is present and we will create one group.
- Go to the Review Navigator toolbar and click on the New Review Group icon. This should open the New Review Group dialog.
- Add information for the new Group. The folder should normally be set to a shared drive that will be accessible to all users. For this tutorial, we will set it to our local drive.
- Once the Group is created it should show in the Review Navigator View tree. It will automatically be added to your tracking groups in the R4E preferences so that it will appear again next time you open Eclipse to use R4E.
- You can now open the Review Group by right-clicking on it and selecting the Open Element command. The Group icon should change from a grayed out icon to a multi-colored one.
- Go to the Eclipse R4E preferences and make sure your user identity is set correctly.
- We will now create some Design rules that can be used during reviews. First create a new Rule Set by slecting the New Rule Set icon in the Review Navigato toolbar. This should open the New Rule Set dialog.
- Add information for the new Rule Set. The folder should normally be set to a shared drive that will be accessible to all users. For this tutorial, we will set it to our local drive
- Now let's create a Rule Area for this rule set by right-clicking on the Rule Set we just created and selecting the New Rule Area from the context menu.
- In the dialog shown, set the Area Name
- Now create a Rule Violation under the Rule Are we just created
- In the dialog shown, set the Violation Name
- Finally, create a new Rule under this Rule Violation
- In the dialog shown, set the Rule values as follows:
We are now ready to proceed to the tutorials.
Tutorial 1: Performing a Basic Review
This tutorial shows how to use R4E by going through a very simple Basic Review. It also introduces how to add Review Items from a Commit to the Version Control System.
- Using the setup created above, create a new Basic Review by right-clicking on the Group we created and selecting the New Review command.
- This will show the New Review dialog
- Once the Review is created, you will notice that new elements were added to the Navigator tree: The review itself, the global anomaly container, and the current user as a new participant to the review.
- You can now browse through the R4E property view, which will appear as soon as you select a new element in the Navigator tree. You will notice that the General Properties tab for the review has the start date property set to when the review was created and that the end date property is set to (In Progress) to indicate that the review is still going on.
- It is now time to add contents to be reviewed. Contents can be added by selecting whole resources (e.g. files directly) or by using the Find Review Items command on Eclipse project if the project is connected to a Version Control System. Here we will assume that the Eclipse projects are connected to Git (using EGit) and we will use the Find Review Items command for the R4E context menu on a given project. Select a project connected to Git and right-click on it to use the R4E->FindReviewItems command.
- This should show the Find Review Items dialog for Git
- We will now pick the current Commit and add it to the review. The Review Navigator view should now show a new Commit Review Item, its children files and their deltas (changes). NOTE: If you do not see the deltas, make sure that the Hide Deltas filter is not set in the Review Navigator Drop-Down menu, Filters sub-menu.
- Let's say we are now done adding review items. At this point we could add new reviewers to the review and notify them that the items are ready for reviews. However, since this is a simple tutorial, we will pretend that we are also the reviewer for this review.
- To open the compare editor and perform the review, we can double-click on any of the file of delta element. Let's pick the first delta of the first file. This will open the compare editor that will show the changes between the new version of the file after the file is committed to the version control system, and the predecessor version. It will also position the cursor to the location of the change (or Delta) we selected in the Review Navigator and highlight it.
- Let's now create a new anomaly on the selected text. To do this, right-click on the selected text and use the R4E->New Anomaly command
- This should trigger the New Anomaly dialog
- Now, let's pretend we are done and the anomaly that the anomaly we highlighted is dealt with. We can now mark this review as completed. To do this, select the Review Element and, in the R4E Properties view, set the Phase property in the view to Completed.
- The review is now completed and we are done with this tutorial.
Tutorial 2: Performing an Informal Review
This tutorial shows how to use R4E by going through a very simple Informal Review. It also introduces how to add Review Items manually, how to remove obsolete items from the Review Navigator view, and how to use Email notifications.
- Using the setup created above, create a new Informal Review by right-clicking on the Group we created and selecting the New Review command.
- This will show the New Review dialog
- As in the basic Review tutorial above, the Review Navigator tree is updated with the new elements. You will also notice that the current participant roles in the Participant Extra Properties tab are set to Organizer and Lead. This is the default and it can be changed if needed. Take note that the icons representing the participants in the Navigator View will change depending on the primary role of the participant.
- It is now time to add contents to be reviewed. In the previous tutorial, we showed how to add a Commit Review Item from a project under revision control. Here we will show how to add a Resource Review Item. Let's say you have a brand new file, not necessarily under revision control, that you want to be reviewed.
- Assume we use a Java project. Open the Package Explorer view, right-click on a file within the target project and trigger the Add Review Item command from the R4E context menu.
The Review Navigator view should now show a new Resource Review Item, its children file and the selection, which in this case will span the whole file from the first to the last lines.
- Now let's add another reviewer to this review by right-clicking on the participants container icon in the review navigator and selecting the New Participant command from the context menu
- This will show the New Participant dialog.
- Note that we added this Participant as a reviewer only. We also set the optional focus area.
- Let's say we are now done adding review items. We will now notify the new Participant we added that the items are ready for review. To do this, right-click on the current review and choose the Send Email/Notification command. When the subsequent dialog appears, select the Notify Particpants of New Items ready for Review.
- This will trigger the Email Client dialog. You can review the contents of the message, modify it as you see fit, and press the OK button to send it. Of course, the destination email address(es) need to be valid for the email to actually be sent.
- Once this is done, the reviewer should receive the email and can start reviewing the code. So, let's say we are now the reviewer and we want to log a general anomaly on the review. We right-click on the Global anomaly container icon in the Review Navigator view and we select the New Anomaly command from the context menu
- This will trigger the New Anomaly dialog.
- Now we should see that the Anomaly was added to the Review Navigator view, prepended with the Anomaly state (which is ASSIGNED at this point). If we do not have any other anomalies to enter, we can indicate that we are done reviewing by setting the review as reviewed by us. To do so, right-click on the Review icon in the Review Navigator and use the Mark as User Reviewed command.
- Since we are done reviewing, a popup dialog appears to ask us to send a Completion Notification to the Review Owner (Lead). Click OK and send the notification email out. The Review Navigator view should now look like this (notice the little check marks that appeared on the review item and its children elements):
- Now, in order to complete the review, we need to resolve the anomaly that was raised. Select the anomaly icon in the Review Navigator view and look at the R4E Properties view detailed tab. We should see the following:
- We see that the optional class and rank are not set for this anomaly, we could have set them after creation, or we can set them here if we want. In order to resolve the anomaly, the author of the code should be notified and the reviewer, lead and author should work together in resolving the issue.
- Once the anomaly is resolved, we can set the Anomaly state to FIXED by changing the State combo box value in the R4E Properties view. Note that the Fixed by property (in the Participant Details expandable section) gets automatically set to the current user. This can be changed to any of the participants if needed.
- Let's pretend that the anomaly is resolved and add a comment to it saying so. Right-click on the Anomaly icon on the Review Navigator view and add a Comment by using the New Comment command from the context menu.
- This will trigger the New Comment dialog.
- We can now complete the review as we've done in the previous tutorial, by setting the Exit Decision field in the Review R4E Properties view->Detailed tab/Decision Information expandable section to Accepted and the Phase field in the Review R4E Properties view->Detailed tab to COMPLETED. Alternatively, we can also complete the review by selecting it in the Review Navigator and using the Progress Review Toolbar command:
- To remove this completed review from the Review Navigator tree so that is does not clutters the view, we can Disable it. To do that, first close the review by right-clicking on the Review element from the Review Navigator view and selecting the Close Element command form the context menu. Then, once the review element is closed, disable it by selecting the Disable element command in the same fashion.
- We are now done with this tutorial.
Tutorial 3: Performing a Formal Review
This tutorial shows how to use R4E by going through a very simple Formal Review. It also introduces how to work with Linked Anomalies, Design Rules, Optional Review Parameters, Review time tracking, and how to use Meetings Notifications.
- First we will add default projects and components to our review group. Select the Review Group icon in the Review Navigator view and go to the Group Detailed properties tab in the R4E Properties view. In the Project and Components expandable section, add Projects and Components to the Group by clicking on the Add buttons for the Available Projects and Available Components tables and typing in some values. We will also add a reference to the Rule Set we created in the setup in the Rule Sets expandable section.
- Using the setup created above, create a new Formal Review by right-clicking on the Group we created and selecting the New Review command.
- This will show the New Review dialog. In this case we will populate the Review optional elements as shown
- As in the other Review tutorials above, the Review Navigator tree is updated with the new elements.
- If you look at the Review Properties Detailed tab, you will notice that is display a Phase Map table. The phase map is only displayed for formal reviews and is used to track the progress of the review. At review creation, the PLANNING phase is the active one.
- It is now time to add contents to be reviewed. As in the basic tutorial review, we will add a Commit Review Item using the Find Review Items command.
- This should show the Find Review Items dialog for Git
- We will now pick the current Commit and add it to the review. The Review Navigator view should now show a new Commit Review Item, its children files and their deltas (changes)
- Now, as in the Informal review tutorial, let's add another reviewer to this review by right-clicking on the participants container icon in the review navigator and selecting the New Participant command from the context menu
- This will show the New Participant dialog.
- Note that we added this Participant as a reviewer only. We also set to optional focus area.
- Let's say that we are done adding new items and participants for this review, we can now transition the review phase from PLANNING to PREPARATION by selecting the Phase combo box in the R4E Properties to the Review. Note that phases can only be changed if we are the phase owner, which we are in this case. We will now automatically be asked to set up a decision meeting by entering meeting details.
- Once the details are entered, the Email client dialog is shown, and upon clicking the OK button, a new notification of items ready for review, bundled with a meeting invitation will be sent to all participants.
- Now, in PREPARATION phase, the users can review the included items. Reviewers can send progress notification or ask questions to other participant by right-clicking on a Review Navigator element and using the Send Email/Notification command. Anybody can also add new Review Items to the review, which will automatically notify other particpants with a New Item Ready for Review notification.
- Let's say we found that part of the new code is not correct, we can select the appropriate change (Delta) in the Review Navigator and directly write an Anomaly on it by right-clicking on the Delta and using the New Linked Anomaly command.
- This will show the New Anomaly dialog. For this anomaly, we will refer to an existing design rule. Expand the Extra parameters section and select the first design rule from the tree. Note that the text fields are set to the value of the anomaly selected.
- We are finished reviewing the files and we will now add the time we spent reviewing the files. We do this by selecting the participant element in the Review Navigator and going to its R4E Properties view Detailed tab, Time Management expandable section. In the Time Spent table, add the time we spent.
- As in the informal review tutorial, we now mark the review as User completed, which will trigger the sending of the completion notification to the review lead.
- The review lead can now move the Review Phase to DECISION in the same way the previous transition was done.
- In the decision phase, it is time to assess anomalies and if necessary assign them to particpants so that they can be handled and fixed. Let's set our Anomaly to ACCEPTED and assign it to a participant. We do this by setting the appropriate values the the R4E Properties Extra tab for the selected anomaly.
- We are now done with all anomalies so we will set the review decision properties. In the Review element R4E Properties, let set the values as follows
- We set the Exit decision to Accepted with follow-up, since some anomalies need to be fixed. We also enter the decision participants and decision time spent values.
- Once the anomaly is fixed, we can change its state to FIXED in the R4E Properties. The fix can now be reviewed by the reviewer, who can set it to VERIFIED. Its properties should now look like this:
- At this point all anomalies are covered and we can complete the review by setting its phase to COMPLETED.
- We are now done with this tutorial.
Basic and Informal Reviews workflows
R4E basic and informal reviews use a lightweight review process and can help to save time while performing reviews involving a small number of participants. It is also recommended to use them when using an agile methodology as development process.
The main difference between Basic and Informal Reviews is that there is no Anomaly state tracking in Basic reviews, while anomalies in Informal review are stateful and need to be closed in one way of another before the review can be completed.
The main differences of Basic and Informal compared to Formal reviews are:
- There are no review phases. Reviews are either Active or Completed.
- Anomalies can be created as long as the review is Active. For example, the author can create anomalies as soon as the review is created.
- The decision meeting is not mandatory.
- It is possible to notify the author/lead of progress in logging anomalies several times in a review. The author/lead can then start fixing some anomalies before the end of the review.
- Anomalies are assigned to the author by default on a per review basis.
There are several ways to perform basic and informal reviews since there are no formal review phases. The below picture describes a typical review that will be described in more detail. Dashed elements in the picture represent optional steps in this scenario.
Create new review
In this scenario, the organizer wants artifacts to be reviewed by one colleague. The author first needs to create the review in R4E. As in formal reviews, this step involves naming the review, identifying participants/roles and identifying relevant input documentation. During the creation of the review, the organizer needs to specify that the review type is basic or informal.
Identify what needs to be reviewed
The organizer uses R4E to specify what needs to be reviewed. This step is performed like for formal reviews using R4E tools to automatically find artifact changes or by manually specifying portions of artifacts that need to be reviewed. The result is a collection of review items.
Items ready for review
The author notifies the reviewer that items are ready to be reviewed. This is done via an email notification that is generated from R4E. In this scenario, no formal meeting is scheduled.
Review item examination, anomaly/time logging
The reviewer examines review items and logs anomalies. The time spent doing this activity can be logged in R4E in an iterative way (e.g. every day).
In this scenario, the reviewer has completed a significant portion of the review (for example, a module/subsystem/feature) and wants to immediately inform the author about it. R4E is used to send a progress notification via an email containing the progress details to the author. Several progress notifications can be sent in a given review.
Examine and fix/reject anomalies
The author relies on the progress notification information to start the anomaly examination. As a result, anomalies can either be accepted or rejected. Accepted anomalies can then be fixed.
When the reviewer has completed the review item examination, R4E is used to send a completion notification via email.
Examine and fix/reject anomalies
The author relies on the completion notification information to complete the anomaly examination. As a result, anomalies can either be accepted or rejected. Accepted anomalies can then be fixed.
Mark review completed
When all anomalies have been fixed, the author can specify the exit decision and mark the review as completed.
Formal Review workflow
R4E uses the IEEE Standard for Software Reviews (IEEE Std 1028-1997) for formal reviews. The process is broken down into four phases.
This process can be adapted to your organization. It is possible to use R4E to perform large reviews with several participants and formal meetings. It is also possible to use R4E for smaller one-on-one reviews with no formal meetings.
During the Planning phase, the review organizer, lead and author(s) define the scope of the review. Together, they specify the list of review items. The review lead also takes care of the overall review scope and planning by specifying aspects like the participants, their roles, the review schedule, etc...
During the Preparation phase, reviewers individually examine review items and record detected anomalies. This activity needs to be performed as preparation for the Decision phase.
During the Decision phase, review participants meet and analyse all submitted anomalies. Together they agree on which anomalies should be accepted and fixed in this particular phase of the project. Anomalies can be rejected because they are invalid or duplicated. They can also be postponed to another project. All accepted anomalies are assigned to the relevant authors for the Rework phase.
During the Rework phase, authors fix all accepted anomalies assigned to them during the Decision phase.
An Author is an R4E Participant that wrote the code being reviewed. Typically, authors are involved in fixing raised Anomalies.
An Anomaly is any condition that deviates from expectations based on requirements specifications, design documents, user documents, standards, etc., or from someone's perceptions of experiences. R4E Anomalies are typically created by reviewers during the review. They can also be found during test, analysis, compilation, or by users of software products or applicable documentation.
In the context of R4E, Comments are user commentaries that are associated to Anomalies as follow-up, or to provide complementary information.
Commit Review Item
A Commit Review Item is a review item that represents the file versions included together in a commit to a Version-Controlled Repository. A commit review item includes the ancestor version (base) and committed version (target) of the files. Commit Review Items are added to a review by Using the R4E Find Review Items command on an Eclipse project.
A Delta represents a single difference in a File Context between the base and target versions. A Delta can refer to content that was modified, added or removed within the file and can span one or multiple lines.
A File Context represents a File included in the review. A file context includes references to the base (ancestor) and target (current) versions of the affected file.
In the context of R4E, Global Anomalies are Anomalies that do not tie to a specific file or part of a file, but are rather applicable to the whole review or are general comments.
A Lead is an R4E Participant that is responsible to monitor the progress of the review is coordinate the wok of the various participants. It should also be the person that has the final say on the closure of the review.
An Organizer is an R4E Participant that create the review and puts together the Review contents. Most of the time, the lead and the organizer are the same person.
A Participant is a user that is part at any given point of a review. A Participant can have one or more roles within the review. Possible roles includes Author, Lead, Organizer, or Reviewer
A Postponed Anomaly is an Anomaly that has been written in a previous review and that was set to state POSTPONED (i.e. it was not fixed/addressed then). Postponed anomalies can be imported in subsequent review to be assessed.
Resource Review Item
A Resource Review Item is a review item that represents a single Eclipse resource (typically a File). Resource Review Items are added to a review by manually selecting the affected file in the workspace
A Reviewer is an R4E Participant that reviews the code under review. Typically, reviewers are involved in raising Anomalies and following up on their resolution.
A Review Group is a set of Reviews bundled together under the same directory and that have common factor(s) as determined by the user (e.g. Same Project, Product, Design Team, Organization, Time Span, etc.)
A Review is a collection of Review Items that are to be reviewed together, by the same reviewers, within a given time period.
A Review Item is a collection of file versions that will be reviewed as part of the current review. There are two types of Review Items currently supported: Commit Review Items and Resource Review Items.
A Rule represents a Design Rule that is to be enforced in the code. Design Rules should be enforced by the reviewers at review time. When a Rule is used in creating an anomaly, its values become the default values for the anomaly.
A Rule Set is a collection of Design Rules that are bundled together as a unit. Rule Sets are associated to the Review Group in which they can be used
A Rule Area is a container for Design Rules related to the same area. E.g. Java, C++, Testing etc.
A Rule Violation is a Container for the multiple design rules associated to a category. E.g. Format, Performance, Syntax, etc.
A Selection represents the part of a File that was manually added to a review. A Selection can span one or multiple lines within a file, or could refer to the whole file itself.
The R4E Navigator View is the main component of R4E. It shows all the information that is available to the user and it is also the place where most user commands are available. The Review Navigator information is organized in a hierarchical tree structure and is presented in a Navigator panel. Commands are available in the view toolbar and in context menus that appear when right-clicking the navigator elements.
Disabling and Restoring Elements
When Review Navigator elements are not relevant anymore (e.g. completed reviews), they can be removed from the view by using the Disable command from the element's context menu.
Disabled elements data is kept, but they will not appear in the navigator view anymore. Take note that currently it is not possible to completely remove references to an element once it is created.
To see disabled elements in the Navigator view, go to the R4E Preferences Filter Tab and select the Show Disabled Elements checkbox and apply the preferences. The disabled elements will show in the Navigator grayed out and with the little disabled decorator icon
Ideally, disabled elements should never be shown, but there could be a need to restore mistakenly disabled elements. To do so, select the Restore command from the disabled element context menu
The Navigator elements can currently be sorted alphabetically or by review type, by selecting the appropriate sorter in the Review Navigator Toolbar menu.
The Navigator view provides different filters that can be used to limit the visibility of elements within the navigator tree. Filters are available in the Review Navigator Toolbar menu.
The filters available are:
- Show Reviews Only: Show only Review Groups and Review elements
- Show My Reviews: Show only Review Groups and Review elements in which the current user is a Participant
- Show Reviews for Participant...: Opens a dialog box where a User ID can be specified. The Navigator will then show only Review Groups and Review elements in which this User is a Participant
- Show Anomalies Only: Only show the Anomalies for the currently open Review and their parent containers
- Show My Anomalies: Only show the Anomalies for the currently open Review that the current User created and their parent containers
- Hide Reviewed Elements: This filter will hide all elements that have been marked as Review by the current User
- Hide Rule Sets: This filter will hide all Rule Sets elements and their children
- Hide Deltas: This filter will hide all Selection and Delta elements.
- Go Into: This filter is a special filter that will take the selected element of the Navigator and put it at the root of the Navigator tree. This is useful to focus on a particular element and its children. It is also possible to set up this filter directly from the View toolbar using the icon.
- Remove All Filters: Remove all currently applied filters and restores the full display of all enabled elements in the Navigator tree.
Setting Elements Reviewed State
To help Users to keep track of the content that was reviewed it is possible to mark relevant Review Navigator elements as reviewed using the context menu Mark/Unmark as User Reviewed command. This will put a little done decorator icon. The marking can be removed by using the same command to toggle the state.
These other commands are also available from the Navigator view toolbar:
- Collapse Navigator tree : Collapse the current Navigator tree
- Expand Navigator tree : Expand the current Navigator tree to the lowest level.
- Select and Open Next Element : Move the selection to the next (lower) element in the tree and opens it in an editor if possible (for File Contexts elements and children)
- Select and Open Previous Element : Move the selection to the previous (higher) element in the tree and opens it in an editor if possible (for File Contexts elements and children)
- Refresh Navigator Data : Fetches data from disk and rebuilds the Navigator tree. This will also show new data that has been added by other users.
- Show UI Legend : Shows a legend that displays and explains all R4E icons in a pop-up dialog.
Handling Review Groups and Reviews
Creating a Review Group
When using R4E for the first time, the first thing to do is to create Review Groups that will hold the R4E review data. Typically, Review Groups include common settings that will be used for multiple reviews. For instance, one can create a Review Group for a design organization, for a given project or task etc.
A given Review Groups is created only once, typically by a "super-user" selected among people that are part of the group.
In order to create the Group, select the New Group icon in the Review Navigator Toolbar.
This opens the New Review Group dialog.
- Add the Review Group Name and (optionally) a brief description in the appropriate text fields.
- Select a shared folder location where team members have access and write permissions (i.e. Review Group shared folder)
- Under the Extra Parameters section, more information can optionally be entered to further caracterize the Group: Default Project, Default Components and Default Entry Criteria values will be available for all Reviews created under this Review Group. Rule Sets defines the available Rule Sets for Review created under this Review Group (see Rule Sets below).
Opening an Existing Review Group
When you create a new Review Group, its references are automatically included in your workspace. To add other Review Group references, open the R4E Preference Group Tab
- Add a new Review Group reference file by clicking the Add button and select the appropriate Group File. Take note that all Review Group filename end with "_group_root.xrer" suffix.
- The Review Group Name and Description are also shown in the Preferences Group tab.
Creating a Review
The Review is the main element of R4E. It is used to group together file that are to be reviewed. There are three type of reviews, Basic, Informal and Formal review (See concepts section for an explanation of the different types of reviews).
To create a new Review, right-click on the parent Review Group under which you want to create the review and select the New Review Command from the R4E Context Menu.
This opens the New Review dialog.
- Add the Review Name and a brief description in the appropriate text fields.
- Under the Extra Parameters section, more information can optionally be entered to further caracterize the Review:
- Project and Components values can be selected from the values entered in the parent Review Group Default Projects and Default Components respectively
- Entry Criteria is taken by default from the parent Review Group value
- Objectives and Reference Materials can be set by the Review creator
Opening and Closing of Review Groups and Reviews
In order to be able to see the Review Group child Reviews, a Review Group must be open. Close Review Group are recognized because of the hollow Group icon they show. You can open a closed Review Group by right-clickindgon it and selecting the Open Element command, or simply by double-clicking on it. Closing unused Review Groups make navigation easier and free up memory and resources, so the Groups should be closed when they are unused.
Likewise, reviews can also be open and closed using the same mecanism. The only difference is that only one review (called the Active Review) can be open at any given time. Opening another Review closes the currently open one.
Take note that Review Groups and Reviews are automatically open after they are first created.
Adding Participants to a Review
Participants are automatically added to the current Review as soon as they add review items to it or create an anomaly. It is also possible to add participants manually.
To do so, right click on the parent review and select the New Participant Command from the R4E Context Menu.
This opens the New Participant dialog.
- Add the Participant Id and E-mail address and optionally User Details in the appropriate text fields.
- Under the Extra Parameters section, more information can optionally be entered to further caracterize the Participant:
- Roles can be assigned to the participant to restrict actions that can be taken. Take note that Roles are mandatory for Formal Review and Optional for Basic and Informal Review types
- Focus Area value can be entered to specify a specific areas this Participant should focus on for this Review
If an LDAP database if configured and connected, the user information could be searched and filled-in automatically using the Find User Dialog
Any field can be entered in the User Information section and by clicking the Search button, an LDAP query will be sent to the database. If any matches are found, the results will be displayed in the Query Results section.
Creating a Review Item
In R4E, Review Items are a collection of one or more files, or parts of files, that are to be reviewed. There are two types of Review Items that exist: Commit Review Items and Resource Review Items.
Creating a Resource Review Item
This item type is created by manually selecting a workspace resource (i.e. File) or a portion of a resource (i.e. line ranges within a given file).
- To create Resource review items for a whole file, right-click a File on a Package Explorer, Navigator or Project View and select the Add Review Item command from the R4E context menu.
- To create Resource review items for a portion of a file, right click a line range selection in an editor or compare editor, or on an element of the outline view and select the Add Review Item command from the R4E context menu.
Once a Resource Review Item is created, it will be shown in the Review Navigator. If you expand the Review Item, you will see the child elements: The file on which the Review Item is applied and the line range selection that is part of the item.
Creating a Commit Review Item
This item type is created by selecting files that were committed to a Version Control System repository. Currently, the only Version Control System supported is Git.
To create a Commit Review Item, right click on a project attached to the Egit team provider (see Project Configuration) and select the Find Review Items command from the R4E Context menu.
This will show the Git connector Commit dialog.
Use the Available Commits combo box to browse through all available commits and select one. For the selected commit, the commit information and affected files appear in the Commit Information and Committed Components sections respectively.
Once a Commit Review Item is created, it will be shown in the Review Navigator. If you expand the Review Item, you will see the child elements: The file on which the Review Item is applied and, optionally if the option is selected in the preferences, the line ranges for the Deltas (or differences between the committed file and its direct ancestor) that are part of the Item.
The icons for the files that are new and were added in the commit will be shown decorated with a little icon The icons for the files that were removed in the commit will be shown decorated with a little icon Files in the commit that are out of sync i.e. for which the version to review and the version present in the users workspace differ will be shown with the > sign prepended to the filename. Such files can be reviewed, but to use the full navigatability provided by the editors, it is stongly recommended that the files be in sync with the workspace whenever possible.
Creating an Anomaly
R4E Anomalies are raised by reviewers to flag problems or add comments on specific parts of the contents as part of the review process.
Anomalies are added in a similar way Resource Review Items are, either from a selected Resource or from a portion/range of a resource, by selecting the Add Anomaly command from the R4E context menu.
Anomalies that are directly tied to a specific selection/delta range can also be created by selecting the Add Linked Anomaly command from the context menu of the affected selection/delta in the Review Navigation View
Anomalies can also be created at the review level. This is useful to flag problems that are not specifically tied to a given file or file part. To do this, use the Add Anomaly Command from the context menu of the Global Anomalies element in the Review Navigator view.
This opens the New Anomaly dialog.
- Add the Anomaly Title and Description in the appropriate text fields.
- Under the Extra Parameters section, if Rule Sets are associated to the parent Review Group, the Rule Sets hierarchy will be shown and, optionally, a design rule can be selected and applied to this anomaly. This will set the Anomaly values with the selected rule values.
Creating Comments on an existing Anomaly
It is possible to add comments to an existing anomaly. This could be useful in discussing the anomaly or for tracking purposes. To create a Comment, use the Add Comment command on the context menu on the selected Anomaly.
This opens the New Comment dialog, where the comment can be added.
Importing Postponed Anomalies
Postponed Anomalies are Anomalies that were written in previous Informal/Formal Reviews, but were not handled then and were instead set to POSTPONED state. If the current Review include files on which these anomalies were written, whether it is the same or a different version of a file, it is possible to import them in the currrent review so that they can be addressed. Currently, only Postponed Anomalies that belong to Reviews under the same Review Group can be imported. Also, take note that Global Anomalies cannot be imported.
To import Postponed Anomalies, just select the current Review in the Navigator View and use the context menu:
R4E will scan all Reviews under the current Review Group and will copy all Anomalies in POSTPONED state that were written on files also included in the current Review. Once the command is done, the imported elements will appear on their own container element under the Review element in the Review Navigator tree.
From then on, Postponed anomalies behave like any other Anomaly and can be handled in the same way. When a Postponed Anomaly is modified, the changes will also be reflected in the original Anomaly (i.e. the one filed in the previous Review). Likewise, any changes that are done by other users on the original Anomaly can be seen in the current review by refreshing the imported Anomalies, by re-issuing the Import command. Take note that Postponed Anomalies that have their state changed from POSTPONED will be disabled. If they are set back to Postponed, they will be restored as Postponed elements.
Handling Design Rules
Creating a Rule Set
R4E support the use of Design Rules, to help reviewers enforce consistent design conventions and rules. A Rule Set is a container that includes multiple related Rule. Rule Sets are independently defined and can be shared among multiple Review Groups. Take note that the use of Design Rules is completely optional.
To create a new Rule Set, select the New Group icon in the Review Navigator Toolbar.
This opens the New Rule Set dialog.
- Add the Rule Set Version and Name in the appropriate text fields.
- Select a shared folder location where team members have access and write permissions (i.e. Rule Set shared folder)
Importing an Existing Rule Set
When you create a new Rule Set, its references are automatically included in your workspace. To import other Rule Set references, open the R4E Preference Rule Sets Tab
- Add a new Rule Set reference file by clicking the Add button and select the appropriate Rule Set File. Take note that all Review Group filename end with "_rule_set.xrer" suffix.
- The Rule Set Version and Name are also shown in the Preferences Group tab.
Creating a Rule Area
In order to create Design Rules, a Rule Area et a Rule Violation containers first need to be created.
Rule Areas represent a logical grouping of Rule Violations. They can, for instance refer to a specific language of element of the architecture. To create a Rule Area, right-click on the parent Rule Set and select the New Rule Area command.
This opens the New Rule Area dialog.
- Add the Rule Area Name in the appropriate text field.
Creating a Rule Violation
Rule Areas contain Rule Violation. A Rule Violation is a logical grouping and Design Rules. They refer to a specific problem highlighted by the Rule e.g. Syntax Error, Bad Naming Convention etc.
To create a New Rule Violation, right-click on the parent Rule Area and select the New Rule Violation command.
This opens the New Rule Violation dialog.
- Add the Rule Violation Name in the appropriate text field.
Creating a Rule
A Rule is the smallest unit in the Design Rule hierarchy. It refers to a specific code convention that is to be followed. The values of the rules are automatically set in anomalies that are created using the Rule as a reference. This can speed up and put some consistency in the review process.
To create a New Rule, right-click on the parent Rule Violation and select the New Rule command.
This opens the New Rule dialog.
- Add the Rule Violation Id, Title and Description in the appropriate text fields.
- Select the Rule Class and Rank in the appropriate combo boxes.
Working with Editors
Once the Navigator view is open and Review Items are present. The items can be reviewed. Files are reviewed using various editor views to browse the content. Currently R4E is fully integrated with the Java JDT and C/C++ CDT editors and will take advantage of the special features these editors provide.
Files can be open in editors by double-clicking on them or their children in the Review Navigator. By default, files belonging to resource review items will be open in single-file editors, whereas files belonging to commit review items will be open in a compare editor. If the file is open using the child Selection/Delta/Anomaly element, then the cursor will automatically be positionned to the start of the line range that corresponds to the element. Files and also be open in the single-file editor by using the Open File in Editor command from the selected element context menu.
Once the file is open, anomalies can be added on the contents by selecting a range in the file and using the New Anomaly command in the R4E context menu.
Working with R4E Properties
Updates to any review elements are performed via the R4E Properties View. If the R4E properties view is linked to the Review Navigator View, it will show up when any Review Navigator element is selected and will show the properties that are associated with this element.
The R4E Properties View is a tab properties viw that consists of three tab.
- The Detailed Tab show properties in an custom view where they can be edited.
- The Classic Tab displays all properties at a glance, using the default Eclipse properties layout. Take note all properties will be read-only in this tab.
Editable properties can be changed directly in the properties view. Take note that some properties can only be set when the element is created, while others could be editable only under specific circumbstances (e.g. a specific element state or review phase for Formal Reviews).
A more detailed description of the properties for each element is shown below.

Using Key Bindings and Hotkeys
Eclipse allows you to customise your keyboard using General>Keys preference page. Within Eclipse, key strokes and key sequences are assigned to invoke a command.
R4E defines some keys as accelerator keys to help the user to perform reviews. Each command starts with ALT +4 as below:
- ALT +4 A : Add Review Anomaly. Available from any editor View. There must be a selection in the editor to create a new Anomaly.
- ALT +4 C : Collapses the Review Navigator View tree.
- ALT +4 E : Expand all elements of the Review Navigator View tree.
- ALT +4 F : Opens a dialog used with the Version Control System connector to Find new Review Items. A Project needs to be selected first before using this shortcut.
- ALT +4 I : Add Review Item. Available from any editor View. There must be a selection in the editor to create a new Review Item.
- ALT +4 L : Add a new Linked Anomaly to the selected Review Navigator Selection/Delta element, if any.
- ALT +4 O : Open the default editor on the selected Review Navigator element, if any.
- ALT +4 R : Refresh the Review Navigator View.
- ALT +4 S : Mark/Unmark the selected Review Navigator element as Reviewed, if any.
- ALT +4 X : Remove (disable) the selected Review Navigator element, if any.
When selecting the accelerator key ALT + 4, if the user waits before selecting the next accelerator key, a commands list like the one shown above will be displayed at the bottom right corner of the Eclipse window.
R4E support sending Meeting and E-mail notifications directly from the Eclipse workbench. Notification send are pre-filled with all the relevant information, making it easy to have standardized communication between the Review participants.
Meeting notifications also can be used to schedule various meetings (e.g. decision meetings) automatically.
Using Email Notifications
E-mail notification can be sent on Review Navigator elements by using the Send Email/Notification command from the selected element context menu.
Once the command is triggered, a dialog appears asking the kind of notification to be sent. Take note that not all the options are available depending on the element selected, the review type and other factors.
Selecting one option and closing the dialog will show up a simple email client pre-filled with all the relevant information. The user is free to modify the information as he sees fit and send the email by clicking the OK button.
Using Meeting Notifications
Meeting can also be scheduled directly in the workbench using R4E. Meeting data generated is in a VCalendar format that is attached to the Email that will be sent. Meeting data for decision meeting is mandatory for Formal Reviews and optional for other review types.
To add meeting data, use the Update button in the Extra property tab, under the Decision Information section, for the selected Review element. This will open the Meeting Information dialog.
The meeting information to enter include the time of the meeting, the duration and location where the meeting will take place. To make the time entry easier, you can use the date selector button (the "..." button on the right side of the Starts text field).
The meeting info stored in the system can be retrive at all time by using the Refresh button in the Extra property tab, under the Decision Information section, for the selected Review element.
Performing Basic Reviews
In R4E, basic reviews are the simplest form of reviews available. Basic reviews are stateless and the anomalies that are raised are also stateless. This means the the participants must track progress of the Review and of the raised Anomaly externally.
Typically, the workflow of a basic review will go as follows:
- Review is created
- Review Items are added, either by manually selecting reources or by automatically selecting files committed using the Find Review Items commmand on the target project
- Organizer/Lead notifies reviewers that the items are ready for review. his can be done externally or by using the Email notification functionality provided by R4E
- Reviewers review the items and raise anomalies as they encounter them.
- At any time there could be communication between the reviewers and the authors of the code under review. Since there is no anomaly state tracking, they will have to agree on how to handle the anomalies raised.
- Once all the reviewers are done and the anomalies are fixed, the review can be set as completed.
Performing Informal Reviews
Informal Review workflow is pretty much the same as the Basic Review workflow, so the steps described above still apply. However, the main difference is the fact that anomalies are now stateful and they need to be addressed/resolved before the review can be closed.
The state diagram for the anomaly workflow is as follows:
- Assigned: This is the state set when the anomalies are created. This is the only non-terminal state
- Deferred: The Anomaly will is valid but will not be fixed now, but at a later time
- Duplicated: The Anomaly is a duplicate of another one
- Rejected: The Anomaly is invalid and will not be fixed
- Fixed: The Anomaly is valid and was fixed. This is normally a terminal state, unless the Revew Exit Decision is set to Accepted with Follow-up, in which case the Verified state is the terminal one.
- Verified: The Anomaly was fixed and verified by the participant that raised it. This state is normally optional, but all Anomalies that are fixed should be subsequently set to verified is the Review Exit Decision is set to Accepted with Follow-up.
Once all the Anomalies are in a terminal state, the review can then be closed as it is done the a Basic Review.
Performing Formal Reviews
Formal Review follow the IEEE 1028-1997 standard. They are stateful and divided into Review Phases. As in Informal Reviews, anomalies created are also stateful.
The state diagram for Formal review workflow is as follows:
The Planning phase is the active phase when the review is initially created. In this phase, the Review Organizer and/or Lead adds the contents that is to be reviewed, either manually or by selecting items from the Version Control System and adds participant that will be part of the review. At the nend of this phase, a notification is sent to the participant that the items are ready to be reviewed, and an invitation to a decision meeting set-up by the Organizer/Lead. Once this phase is completed, it is impossible to go back to it.
The Preparation phase is the phase where participants review the items included in the review and potentially raise anomalies. Once all reviewers have completed their tasks (and notified the Organozer/Lead), then the review can progress to the next phase.
The Decision phase is where all the anomalies that were logged are analyzed and a decision is made on each of them on how to handle them. Potential outcomes include fixing the problem flagged by the anomaly, deferring it, or rejecting it if it is not valid. Once all the Anomalies are examined, a decision can be taken on how to close the review. The possible outcomes for the review at this stage is that it could be rejected and more reviewing/rework is necessary, it could be accepted as is, or it could be conditionnaly accepted, provided that the outstanding anomalies are fixed.
The Rework phase is an optional phase, only used when a review is conditionally accepted, in which valid anomalies are fixed. Once the fixed are included, the anomalies will need to be re-checked to verify that the fixes are acceptable. When all the fixes are verified, the Review can be completed.
Take note that there is a slight difference between the anomaly states in Informal Reviews and the ones used in Formal Reviews, as it can be seen below:
A new Anomaly in a Formal Review is set to CREATED by default. During the decision phase, it could be set to the same values as in Informal Reviews, and it can also be set to ACCEPTED, which means that the anomaly is deemed valid and will be handled and fixed. There is no ASSIGNED state for Anomalies in Formal Reviews. The rest of the anomaly flow is essentially the same as with Informal Reviews.
Statistical reports provide useful information to analyze the efficiency of one or several reviews.
To generate a statistical report, select in the Review Navigator view one or more review, the right click and select "Generate Report"
Two types of report can be generated.
- Inspection record: when you select only one review to generate a report, this type of report will be initiated. You will see a list of anomalies at the end of the report.
- Global report: when two or more review are selected. It gives a summary of information based on the selected reviews.
The report folder is located under the group folder. The group folder is specified in the R4E preferences,
If the user is not allowed to create a report in the existing group report directory, a new pop-up allows the user to select or to create a new directory to save the requested report. The user can enter a path or select the Browse button to select a location where to store the report.
When the report generation is completed, a pop-up window will indicate where the report was stored.
Once the OK button is clicked, the HTML report will be displayed in the default web browser or in the Eclipse web browser all depending on the Eclipse web browsing preferences.
This section lists the reviews that were selected for the report. The review name, group, component, review item type, review type and project information are displayed for each review.
