1999 2000 2001 2002 Bernd Gehrmann 2004 Carlos Woelz &FDLNotice; 2004-06-06 2.01.90 &cervisia; provides a graphical view of &CVS;. KDE tdesdk Cervisia CVS version control revision control &cervisia; is a user friendly version control system front-end. The aim is to support &CVS; and other version control system programs in a unified interface, featuring conflict resolution, difference and history viewers, status for the working copy files, and support for most version control functions. You can get &cervisia; by building the tdesdk module or installing the tdesdk package provided by your distribution. Currently, only &CVS; is supported, but other version control systems may be integrated in the future. A version control system is a tool to record, manage, and distribute different versions of files. &CVS; is a version control system. It allows you to share your modifications easily, as each of the contributors can work on their local copy at the same time, without fear of overwriting each others' modifications. It allows the recovery of past versions (useful for tracking bugs), the creation of branches (for experimental development or for releases of code) and more. The main repository usually holds a collaborative project (commercial or not), but you can take advantage of the nice revision control features offered by &CVS; even for a project developed exclusively by you. It is easy to set up a local repository, and you will gain the ability to track changes that caused bugs, revert changes, avoid accidental loss of information, &etc;. The repository holds the project files, and every contributor keeps their own local copy, named working copy or sandbox; one can then add their modifications to the main repository (a process called "committing") and/or update their own copy to reflect recent changes made by other contributors. In this section, we show how to use the basic version control system functionality using &cervisia; to checkout modules from the repository and work with them. To do that, you must have access to the repository as a client, meaning that someone (probably the administrator of the &CVS; repository) gave you an account on the server machine. Alternatively, you can easily create a local repository for your own project. If you plan to develop a complex project, it is a good idea to use the &CVS; features, even if you are the only developer. You can make all changes in the working copy, and use &cervisia; (or any other &CVS; tool) to update and commit. This way, you will gain the ability to track changes that caused bugs, revert changes, avoid accidental loss of information, &etc;. Using &cervisia;, it is simple to create a local repository. Open the Create New Repository (cvs init) dialog by choosing Repository Create.... Press the ... button to select the folder where you want to create the repository, or enter its location in the text box. For instance, if you want to place the repository in the /home/user folder, and to name it cvsroot, you should type /home/user/cvsroot in the text box, or select the /home/user folder using the file picker, and add cvsroot. Confirm by pressing the OK button. &cervisia; will create and initialize the new repository folder. Now you can import your current work to the repository, or simply create a folder in the repository to start a new module from scratch. &cervisia; offers an integrated front-end to manage all your repository locations, the Configure Access to Repositories dialog. To display it, select the Repository Repositories... menu item.

A screenshot of &cervisia;'s Configure Access to Repositories dialog

There are several methods to access a CVS repository. It may be reached via password authentication (:pserver:), secure shell (using :ext:), local repository (:local:), &etc;. The format for the repository location is (optional items appear between square brackets): [:method:][[user][:password]@]hostname[:[port]]/path/to/repository Not all these items (user, password, hostname, port) are always necessary to access the repository. The required information depends on the access method used, which can be categorized as follows: Local The local access method is the default method used by &CVS;. Therefore, it is optional to add the :local: method to the repository location: you can enter simply the path to the folder which stores the &CVS; repository, and is accessible from your computer, like /path/to/repository or to give a real life example, /home/cvs. It may physically be on a disk which is mounted via NFS, but this is an irrelevant detail. If you created a local repository, the location will be simple the path to it. rsh The repository location is something like :ext:username@host.url.org:/path/to/repository. This method requires that you have a user account on the server machine (in this example, host.url.org) and use a remote shell for communication. By default, &CVS; uses ↱ for this purpose; however, ↱ has long considered to be insecure, and is widely replaced by &ssh;. If you wish to use &ssh;, you must set the environment variable $CVS_RSH to &ssh; when using the cvs client. &cervisia; supports this easily. Note that &cervisia; cannot answer possible password requests from the server machine. You must make sure that a remote login works without requiring you to enter the password. With plain vanilla ↱, this can be achieved for example by creating a .rhosts file in your home folder with a list of trusted hosts (see the ↱ manpage). With &ssh;, it can be achieved by copying your public key located in the file identity.pub, located in the $HOME/.ssh/ folder to the server. In this case, the key must not be encrypted with a passphrase (see the &ssh; manpage and the &CVS;/SSH FAQ on SourceForge). If you are unsure about these issues, ask your system administrator. pserver The repository location looks like :pserver:username@host.url.org:/path/to/repository This method accesses the server via a special protocol with a relatively weak authentication (pserver stands for password authentication). Before you can use such a server, you need a username and password given by the &CVS; server administrator, and you have to login. Note that your &CVS; password authentication username does not necessarily match the system's username. Before accessing the &CVS; server, you will need to login. Open-source projects typically offer Anonymous CVS access to their sources. This means you can easily grab the latest sources, modify, and create patches (differences) against the repository without asking for a CVS account. As a general rule, Anonymous CVS uses password authentication (:pserver:), and is a read-only repository, not allowing you to upload your changes directly. Knowing the access method and location to the repository, you can add it to &cervisia;'s repositories list: Open the Configure Access to Repositories dialog by choosing the Repository Repositories... menu item. Press the Add... button to open the Add Repository dialog. Enter the repository location in the Repository: text box. &cervisia; will automatically disable the areas of the dialog that are not relevant to the access method you entered. If you are using the ext method to access the repository, enter the remote shell you wish to use (⪚ &ssh;) in the Use remote shell (only for :ext: repositories): text box. Press OK. You will see the repository you just entered on the repositories list. If the access method to the repository you just entered is password authentication (pserver), you will need to login before connecting the server. Click the repository on the list to select it, and press the Login... button. Enter your password in the upcoming dialog. If you successfully enter your password, the Status column entry of the pserver repository will change from Not logged in to Logged in. Press OK to apply your modifications, or add another location to the list. &cervisia; will store as many locations as you like. In this section, we discuss how you can put a new project into the &CVS; repository. If you just want to work with an existing project which is already in a repository, you may skip this section. There are two ways to put a project into the &CVS;: Import the files and folders to a new module, using &cervisia;'s import dialog. Modules are the top folders in the &CVS; repository folder tree, and are used to separate and organize the different software projects inside the repository. Create an empty module and add the new files and folders manually. You will have more control, but it will probably take a little more time. Keep in mind that &CVS; was initially designed to handle text files. Many features, like revision merging, creating differences in a readable form, &etc; are only performed to text files. This does not mean you cannot use CVS to keep binary files, it just means you have to explicitly tell CVS if it is a text or binary file. If you declare the wrong file type, you will experience problems with the &CVS; functionality for these files, and they may get corrupted. Importing a project (as a new module) has some advantages: you will import all files and folders recursively, and the module will automatically be created for you. This makes importing large existing projects to the repository easier. However, there are some disadvantages: you cannot use &cervisia;'s import dialog to add files to existing modules, and you can either import the files as text or binary files. You can work around this limitation by creating a folder with files of only one of the types, or by informing the patterns of the files that should be ignored during the import process. For instance, suppose your project contains text files and some PNG images (binary files) only. You can tell &CVS; to ignore all files with the pattern *.png while importing the other files as text, or you can move the images to a separate folder, and then import the remaining files (as text files). Either way, you will have to checkout the newly imported module to a new working copy, copy the missing files and folders to it, add and commit them to the repository to complete the import process. As an alternative, you can add the files and folders manually, creating an empty module for them. To add an empty module to a repository, just create a new folder in the &CVS; repository root folder. The name of this new folder will be the name of the module. Checkout the new empty module. Then copy the files and folders to the working copy, add and commit to upload them to the &CVS; repository.

A screenshot of &cervisia;'s import dialog

In you can see the dialog which helps you to import a project as a module. To access &cervisia;'s import dialog, choose the Repository Import... menu item. Repository: Enter or select on the dropdown list the name of the &CVS; repository, also known as $CVSROOT. You must have write access to it, and the repository must be properly initialized. If the repository does not yet exist, you can create one choosing the Repository Create... menu item. The drop down box shows a list of the repositories you previously entered using the Configure Access to Repositories dialog box. If the repository is remote, make sure that authentication works. See for more information. Module: The name of the module under which the project will be stored. After the import, the project can be checked out under this name. See for more information. This is also the name of the corresponding folder in the repository. Working Folder: The toplevel folder of the project you want to import. The import starts from this folder and goes down recursively. Vendor tag: The vendor tag is historically used for tracking third-party sources. Just use your user name if you have no better idea. It does not matter much what you enter here. Release tag: This tag is also historically used for importing different versions of third-party software. If you are not doing this, use the word start or a string FOO_1_0 where FOO is the name of your project and 1.0 is the version number of the imported release. Ignore files: If you fill out this field, an additional -I file names option is given go the cvs import command. This entry is interpreted as a whitespace-separated list of file name patterns which are ignored. In general, a cleaner and less error-prone way to control which files go into the repository is to create a folder with only the files which you want to import and start from that. Nevertheless, this entry may be useful if the project contains files which are by default ignored by &CVS;, ⪚ files with the name core. In such a case, simply enter the character ! in this field: this overrules &CVS;'s scheme of ignored files, see . Comment: Use this field to record the comments you might have about the origin, use, development, &etc; of the files you are importing. Import as binaries If you check this box, all files are imported in binary mode, i.e. an argument -kb is given to cvs import. Use file's modification as time of import If you check this box, the time of import will be the file's modification time instead of the import time. After you have filled out this form and confirmed by pressing OK, the following &CVS; command is used: cvs -d repository import -m "" module vendortag releasetag Now that you successfully defined your repository location, and imported the initial files to the repository, it is time to retrieve the module from the &CVS; repository, creating your working copy. You should also know the name of the branch or tag you want to use. Branches of a module are parallel versions of this module. A good real-life example of the use of this feature is the release of a software project. After a major release, there are bugs in the code that should be fixed, but people want to add new features to the application too. It is very hard to do both at the same time because new features usually introduce new bugs, making it hard to track down the old ones. To solve this dilemma, &CVS; lets you create a parallel version, that we will call the "stable release branch", where you can only add bugfixes, leaving the main branch (HEAD) open for adding new features. Tags are used to mark a version of a project. &CVS; stamps one version of each file with the tag, so when you checkout or update to a specific tag, you will get always the same file versions. Therefore, in opposition to branches, tags are not dynamic: you cannot develop a tag. Tags are useful to mark releases, big changes in the code, &etc;. Using tags, you can easily return the project to a previous state, to reproduce and track bugs, generate the release code again, &etc;.

A screenshot of &cervisia;'s checkout dialog

Repository: The name of the &CVS; repository, also known as $CVSROOT. The drop-down box shows a list of the repositories you previously entered using the Configure Access to Repositories dialog box. If the repository is remote, make sure that authentication works. See for more information. Module: The name of the module to be checked out. If you are working with an existing repository, you can probably get this name from the system administrator; or, if it is an open-source repository, you can get the module names from the project web pages. If you want to create a new module from scratch using a local repository, just create a new folder in the local repository root folder. The name of the folder will be the same as the name of the empty module. Alternatively, if the repository has a $CVSROOT/modules file, you can retrieve a list of available modules by pressing the Fetch list button. Note that it is possible to checkout any existing subfolder of the module, without retrieving the rest of the module. Just enter the path to the subfolder as well. For instance, if you want to get only the doc/cervisia subfolder of the tdesdk module, enter tdesdk/doc/cervisia in this field. Branch tag: The name of the branch or tag you want to check out. If you leave this field empty, &cervisia; will retrieve the main (HEAD) branch. Working folder: The folder under which the module should be checked out. Note that the the working copy toplevel folder is named after the module you are retrieving, unless you give it an alternative name in the Check out as: field. Check out as: This results in the working copy files being checked out to an alternative folder under the working folder rather than a folder named after the module. Export only If you check this box, the files will be exported rather than checked out. Exporting obtains a copy of the source for the module without the CVS administrative folders. For example, export may be used to prepare the source code for a release. When you start &cervisia;, and open a working copy by choosing File Open Sandbox... , you can see two main areas in &cervisia;'s main window: the top one is a hierarchical (tree) view of the current working copy; the bottom area is used to display the &CVS; commands &cervisia; issues to perform its tasks, as well as the output generated by these commands. By default, &cervisia; does not display the files contained by the sub-folders, so you will have to click the folders you want to see. To display all files of the working copy, select View Unfold File Tree . To close back all folders from the working copy, choose View Fold File Tree . According to the settings in your .cvsignore files, the files you usually do not want to include into the repository - such as object files - are not shown in the tree view. For each file, you see its corresponding status. In the default setting, after opening the sandbox, this is "Unknown" because &cervisia; delays the fetching of information until you select the files and folders whose status you want to update or view and choose File Update or File Status . With this approach, you have a minimal amount of functionality available even if you do not have a permanent connection to the &CVS; server.

A screenshot of &cervisia;'s main view

The commands in the File menu usually act only on the files which you have marked. You may also mark folders. Now choose File Status or press F5. &cervisia; issues a cvs update -n file names command to get status information for the marked files. Note that &cervisia; goes recursively into subfolders only if you have the according option in the Settings menu set. According to the respective file's status, you now see an entry in the Status column: Locally Modified This means you have modified the file compared to the version in the repository. Locally Added This means the file does not exist in the repository, but in your working copy and you have scheduled it for addition. The actual insertion into the repository only happens after a commit. Locally Removed This means you have scheduled the file for removal, but it still exists in the repository. The actual removal happens only after a commit. Needs Update This is shown if a newer version of the file exists in the repository, e.g. because someone committed a modification. Normally, you want to update this file so you have an up-to-date version in your folder. Needs Patch This is essentially the same as before; the difference is that in case of an update, the &CVS; server transfers only a patch instead of the whole file to you. Needs Merge Indicates that a merge of the revision of this file in your working copy with the version in the repository is necessary. This typically happens if you have made modifications to the file while someone else has committed his modifications. If you choose to update, the modifications in the repository are merged into your file. In case of a conflict (i.e. if someone else has changed some of the same lines like you) the new status is then "Conflict". Up to Date Indicates that the file is identical with the version in the repository. Conflict This is shown if this file still has conflict markers in it. Maybe you have previously updated the file and not resolved the conflicts. Not In CVS Indicates that the file is not registered in the &CVS; repository. If you want it to available for others, you should add it to the repository. If not, you may consider adding it to your .cvsignore file. Now that you have got an overview of the current status of the CVS, you may want to do an update. Mark some files (or the root of the folder tree which is equivalent to marking all files in this folder). Now choose File Update (Of course, you could have chosen this at the beginning of the session). For some of the files the status may change now. Typically, files which had "Needs Patch" or "Needs Update" are updated. So the following new items are possible in the status column: Updated Shown if the file was updated from the repository. Patched Indicates that the &CVS; server has sent a patch for this file and the patch has been successfully applied. If the patch was not successful because there was a conflict between your modifications and those someone else committed to the repository, the status is now Conflict. You may have noticed that according to the status of the file, its row has a different color. The colors are chosen to somehow reflect the priority of the status. For example, a file with a conflict is marked red to show you that you have to resolve a conflict before you can continue working with the file. If your folder contains a high number of files, you may nevertheless lose the overview. To get more concise information about which files have an unusual status, simply click on the header of the Status column. The file list is then sorted by priority, so you have all important information at the top of the list. To get back to the alphabetically sorted view, click on the header of the File name column. All commonly used &CVS; functionality is directly available in &cervisia;'s main view. Commands usually act on several files at once, namely all which currently selected. If the selection includes folders, its interpretation depends on the settings made under the Settings menu. For example, if SettingsCommit and Remove Recursively is checked and you choose FileCommit... while a folder is selected, then all files in the tree under that folder are committed. Otherwise, only the regular files in the folder itself are affected.

The most used actions are also available by right clicking the files in the tree view, through the context menu. shows &cervisia;'s main window pop-up menu. You can simply edit a file by double-clicking on it or selecting it and pressing &Enter;. This starts the default application that handles that file type (the default application for each file type is a KDE wide setting). If the default application is not the one you want to use, you can right click the file and choose the Edit With submenu, and select one of the other applications that handle that file type. Adding files to a project requires two steps: first, the files must be registered with &CVS;, or in other words, added to the repository. This is necessary, but not sufficient. In order to actually put the files into the repository, you must commit them. This procedure has an important advantage: you can commit the files together with modifications to other parts of the project. When doing this, one can easily see (⪚ in commit emails) that all these changes are part of a whole. To this end, mark all files to be added in &cervisia;'s main view. Then, choose FileAdd to Repository..., or right click the marked files and choose Add to Repository.... The CVS Add dialog will appear, listing the files you marked, and asks for confirmation. Press OK. &cervisia; issues a command cvs add file names If the operation was successful, the status column should have "Added to repository" for the added files. &CVS; is not designed to provide meaningful revision control for binary files. For example, merging binary files normally does not make sense. Furthermore, by default &CVS; performs keyword expansion (⪚ on the string $Revision: 1.6 $) when a file is committed. In binary files, such replacements may corrupt the file and make it completely unusable. In order to switch the above behavior off, you should commit binary files (or other files, like Postscript or PNG images) by choosing FileAdd Binary.... The CVS Add dialog will appear, listing the binary files you marked, and asks for confirmation. Press OK. &cervisia; issues a command cvs add -kb file names Like adding files, removing files is done in two steps: First, the files have to be registered as removed by choosing FileRemove From Repository... or right clicking the marked files and choosing Remove From Repository... from the context menu. The CVS Remove dialog will appear, listing the files you marked, and asking for confirmation. Press OK. &cervisia; issues the command cvs remove -f file names After that, this modification to the sandbox has to be committed, possibly together with other modifications to the project. The above command only works if the file is up-to-date. Otherwise, you get an error message. This behavior is sensible: If you have modified the file compared to the version in the repository, or if someone else has made any modifications, you will first want to check if you really want to discard them. Folders are handled fundamentally different from ordinary files by &CVS;. They are not under revision control, i.e. you cannot tell which folders existed in the project at a certain time. Furthermore, folders can never be explicitly removed (except by removing them directly in the repository). As a substitute, &CVS; follows the convention that a folder is "non-existent" in a version of the project if it is empty. This convention can be enforced by using the option -P to cvs update and cvs checkout. This option can be set in the menu SettingsPrune Empty Folders on Update. A folder can be added to the repository choosing FileAdd to Repository... or right clicking the marked folder and choosing Add to Repository... from the context menu. Note that in contrast to adding files, adding folders does not require a commit afterwards. &cervisia; issues the command cvs add dirname When you have made a certain number of changes to your working copy, and you want other developers to have access to them, you commit them. With a commit, you place your versions of the modified files as new revisions into the repository. A subsequent update by another developer will bring your modifications into their working copy. In order to commit a couple of files, select them in &cervisia;'s main view and choose FileCommit... or right click the marked files and choose Commit... from the context menu.

You get a dialog that shows you a list of the selected files on the top section and a log message for your changes below. &cervisia; helps you in several ways to find a meaningful log message: first, in the file list you can double-click a file or press Return in order to see the changes you have made to the file. Second, it gives you a list of log messages you have previously used in a combo box. Third, this dialog is integrated with &cervisia;'s changelog editor described below. When you have finished the dialog, the command cvs commit -m message file names is used. A common error you may encounter when committing is Up-to-date check failed. This indicates that someone has committed changes to the repository since you last updated; or, more technically, that your BASE revision is not the newest on its branch. In such a case, &CVS; refuses to merge your modifications into the repository. The solution is to update, resolve any conflicts and commit again. Of course, if you are working on a software project, it is normally good style to check if the program still works after you have updated - after all, there could be bad interactions between your modifications and the other modifications which break the code. Another popular mistake results in the error message Sticky tag 'X' for file 'X' is not a branch. This happens if you try to commit a file which you have previously brought to a certain revision or tag with the command %cvs update -r X (which is ⪚ used by the menu item AdvancedUpdate to Tag/Date...). In such a case, the tag on the file gets sticky, i.e. further updates do not bring you to the newest revision on the branch. If you want to commit further revisions to the branch, you have to update to the branch tag before you do further commits. With &cervisia;, it is quite easy to maintain a ChangeLog file that is compliant with the format laid out in the GNU coding guidelines. To use it, choose FileInsert ChangeLog Entry.... If a file with the name ChangeLog exists in the toplevel folder of your sandbox, this file will be loaded and you have the possibility to edit it. To this end, at the top of the file, an entry with the current date and your user name (which can be configured as described in ) is inserted. When you finish the dialog this dialog by clicking OK, the next commit dialog you open will have the log message set to the message you last entered in the ChangeLog. Conflicts may occur whenever you have made changes to a file which was also modified by another developer. The conflict is detected by &CVS; when you update the modified file; &CVS; then tries to merge the modifications committed by the other developer into your working copy. The merge fails if both your and his modifications are in overlapping parts of the file, and the &CVS; server issues an error message. In &cervisia;'s main view, files with conflicts are indicated with "Conflict" in the status column and with a red color. It is your job now to resolve these conflicts before you commit the file. &CVS; will refuse to commit any files with conflicts until they have been edited. From the main view, you can of course resolve conflicts the traditional way: just double-click the file in question and edit it with your favorite editor. &CVS; marks the conflicting changes by placing marks in the middle of the files, in the following manner: <<<<<<< Changes in your working copy ======= Changes in the repository >>>>>>> revision_number You should replace this whole block with the new merged version. Of course, you have a great amount of freedom when resolving a set of conflicts: for each conflict you can decide to take one of the two alternative versions. You can also decide that both approaches are broken and rewrite a whole routine or the complete file from scratch. Fortunately, &cervisia; offers a nicer interface for handling these conflicts. This does not mean that you will never need to manually edit the files, but at least can eliminate the need to do so for the trivial conflict resolution. To use &cervisia;'s CVS Resolve dialog choose FileResolve... or right click the marked file and choose Resolve... from the context menu.

A screenshot of &cervisia;'s resolve dialog

On the top of the dialog, you see Your version (A) of the file on the left hand side and the version in the repository, Other version (B), on the right hand side. The differences between them are marked in red color. Below these two versions, you can see the Merged version. The merged version reflects what that section will be in your working copy if you press the Save button. You can go back and forward between the conflicting sections by pressing << and >>. In the lower middle of the dialog you can see which section is currently marked. For example, 2 of 3 means that you are currently at the second differing section of 3 total. Now can can decide section by section which version you want to have in the merged file. By pressing A, you take over the version you edited. By pressing B, you take over the version from the repository. By pressing A+B, both versions will be added, and your version will come first. B+A yields the same result, but the order will be different: first the repository version, then yours. If you are not happy with any of these versions, press Edit to open a simple text editor where you can edit the section. When you are finished editing, press OK to return to the CVS Resolve dialog and resume solving conflicts. You will see the section you just edited in the Merged version, with your modifications. To save your modifications, overwriting the working copy version, press Save. Note that this will save the choices not only the section you are currently viewing, but all sections in the file. If you want to save it to another file, press Save As.... Press Close to exit the dialog. If you close the dialog without saving, the changes you made will be lost. There are several places in &cervisia; where you can ask for a window showing the differences between revisions of a file: In the main view, you can choose ViewDifference to Repository (BASE).... This is based on the command cvs diff and shows you the differences between the version in your sandbox and the version to which you last updated (also known as BASE). This is in particular useful just before you commit a file, so you can find an appropriate log message. You can view the differences between the version in your sandbox and the version in the main development branch (also called HEAD) by choosing View Difference to Repository (HEAD).... You can view the differences between the last two revisions of the selected file choosing View Last Change.... You can access the Difference to Repository (BASE)..., Difference to Repository (HEAD)... and Last Change... menu items from the main view context menu, by right-clicking the file you want to view. In the dialog that is shown when a you commit a set of files, you can request a difference window by selecting a file name in the selection list, either by double-clicking it or by pressing Return. This is quite similar to using ViewDifference to Repository (BASE)... with the respective file in the main view. In the Browse Logs dialog, you can mark two revisions of a file and request a dialog showing the differences between them (see ). As you may have expected, &cervisia; does not just dump the output of the diff command into your terminal, but shows you a graphical view as seen in .

A screenshot of &cervisia;'s diff dialog

The text in the dialog is an improved variant of the text given by the diff command with the -u option. You can see the differing versions in two windows, with lines arranged such that you can do a side-by-side comparison. That means, where text has been added or deleted, the respective window shows empty lines with the marker +++++ at the left hand side. Elsewhere, you can see the running number of each line in the left column. In the second column in the right window, you can see which kind of change has been made. Possible types are Add, Delete and Change. The respective lines are marked in blue, green and red color. In the middle of the dialog a compressed image of the color markers is shown. In this way, you can get a quick overview of the overall changes to the file. You can also use the position of the colored regions in the compressed image as an orientation when you using the scroll bars. Normally, the scrollbars at the left and the right window are synchronized, i.e. if you scroll on the left hand side, the right hand side is scrolled by the same amount. You can change this by checking the box Synchronize scroll bars. For information about how to customize the diff dialog, see . Sometimes you want to offer your modifications for review, before committing them, or you do not have write access to the repository (therefore you cannot commit). &CVS; offers standard formats to share the modifications in your working copy, so other people can review your changes, test them in their working copy and apply them to the &CVS; repository. A file containing these differences is called a patch, and is generated by the cvs diff command, in the same way as the differences in . Sharing patches instead of sets of files requires less bandwidth, and patches are easier to handle, as you can send only one patch file containing all the differences from many source files. &cervisia; gives you access to this feature by choosing Advanced Create Patch Against Repository.... The Create Patch Against Repository... action creates a patch with all modifications in all files in your working copy (sandbox) against the BASE repository. Therefore, the selection of files in the main view does not affect the patch that will be generated. Another possibility is to select one file in the main view and choose Browse Log... from the View menu or right click the marked file and choose Browse Log... from the context menu, in order to open the Browse log dialog. Now, select the version you want to create a patch against, as revision "A" and press the button Create Patch.... This will generate a patch with the differences between the marked file in your working copy and the version selected as revision "A". Before generating the patch, &cervisia; displays a dialog allowing you to configure the output format.

Output Format There are three output formats available: Normal: a format that can be used to cause the ed editor to automatically make another copy of the old file match the new file. In the normal output format, the characters < and > mark the changes, and there is no context information. Unified: the most used format for exchanging patches. The unified format uses context lines in addition to line numbers to record the differences. This makes the process of applying patches more robust. This format displays the differences in a compact and readable form, with a header for each file involved, and separate sections (chunks) for each difference. The context lines available for each difference make reading the modifications easier. In the unified output format, the characters + and - mark the changes. Context, which presents the same information as the unified format, but in a less compact way. In the context output format, the character ! marks the changes. Number of context lines: Set here the number of context lines for the unified or context output formats. This option is not available for the normal output format, as in this format no context information is recorded. More context information makes reading the raw output easier, and applying the patch more precise, but increases the patch size. It is recommended to use at least two context lines for proper patch operation. Ignore Options Check here the changes that should not be considered as differences when generating the patch. After setting the output format, &cervisia; generates the patch and displays the Save As dialog. Enter in this dialog the file name and location of the patch file. With the command cvs annotate, &CVS; offers the possibility to see - for each line in a file - who has modified a line the most recently. This view may be helpful in order to find out who has introduced a change in the behavior of a program or who should be asked about some change or bug in the code. &cervisia; gives you access to this feature, but it further enriches the information in an interactive way. You obtain an annotate view by choosing ViewAnnotate.... Another possibility is to press the button Annotate in the Browse log dialog, in which you can select which version of the file you want to display. In you can see a screenshot of the dialog.

A screenshot of &cervisia;'s annotate dialog

In the annotate dialog, you see in a window the latest version of the selected file (or the revision "A" version, in case you launched the annotate dialog from the the Browse log dialog). In the columns before the text, you get some information related to the latest change in each line. In the first column the line number is displayed. In the second column you see the name of the author and revision number. Finally, in the third column you see the actual content of that line. Consequently, when a certain line appears strange to you or you assume a bug there, you can immediately see who is responsible for that line. But not only that, you can also find out why that line was changed. To this end, move the mouse cursor over the respective revision number. Then a tooltip appears that shows the log message and the date of the change. When you mark one file in the main view and choose Browse Log... from the View menu or right click the marked file and choose Browse Log... from the context menu, the CVS Log dialog is shown (if you mark more than one, nothing happens, as &cervisia; can only generate and parse the log for one file at a time). This dialog offers functionality that is beyond viewing the file's history. Using it as a version browser you can: View the revision, author, date, branch, commit message, and tags for each version of the marked file. View a graphical tree representation showing the branching and tagging of the marked file. View any version of the marked file (with the default application). Watch an annotated view of any version of the marked file View the differences between any pair of versions of the marked file, including pairs with the current working copy version of the marked file. Create patches containing the differences between any pair of versions of the marked file, including pairs with the current working copy version of the marked file.

You can choose to see the history as provided by the cvs log command (CVS Output), as a Tree, or in List form. What you prefer is of course a matter of taste and it depends on what information you are interested in. The tree is an intuitive representation of what has been done on different branches by which authors. As tooltips, you can see the corresponding log messages. The list is by its nature linear and, therefore, does not give an immediate view of branches; on the other hand, it concentrates more otherwise relevant information on less screen estate, namely the time of each change of the file and the first part of the log message. The CVS output information is complete, but long, and difficult to read. To alleviate these problems, you have the ability to search the text of the CVS output, by pressing the Find... button. To obtain more information about a certain revision, you can click on it either in the list or the tree view. The fields in the middle of the dialog are then filled with the complete information provided by cvs log. You can mark two revisions, called "A" and "B", which are relevant if you make use of further features provided by the buttons. Revision "A" can be chosen with the left mouse button, revision "B" with the middle one. In the list view, you can also navigate with with your cursor keys. In order to mark revisions "A" and "B", use the keybindings CtrlA, CtrlB, respectively. Using the CVS Output view, you can click on the Select for revision A and Select for revision B to mark the revisions. If you press the Annotate button, you get a dialog showing the text of file belonging to the revision marked as "A". Every line is prefixed with the information about who edited this last time, and at which revision this happened. You can get more information about viewing annotated versions in . If you press the Diff button, a cvs diff call is issued and you get a dialog in which all the modifications between the two marked revisions are shown. If you mark revision "A", but not revision "B", &cervisia; will generate the modifications between the file version marked as revision "A" and the working copy version of the file. This allows you to view the differences between your version of the file and any version available in &CVS;. To make it easy to see the changes, different colors are used to mark lines which have been added, removed or simply changed. You can get more information about viewing differences in . If you press the Create Patch... button, you get a dialog in which you can set the format options for generating a file containing all the modifications between the two marked revisions which are shown. If you mark revision "A", but not revision "B", &cervisia; will generate the modifications between the file version marked as revision "A" and the working copy version of the file. This allows you to generate a patch, or difference file, between your version of the file and any version available in &CVS;. After configuring the format of the patch in the dialog, and pressing OK, a cvs diff command is issued to generate the difference file. A Save As dialog will pop up. Enter the file name and location of the patch file &cervisia; generated, in order to save it. You can get more information about creating patches, and the patch format options in . If you press the View button, &cervisia; will retrieve the revision marked as "A" and display it using the default application for its file type. Press the Close button to leave the dialog and return to the main view. To generate the log that is the base for the CVS Log dialog, &cervisia; issues the following command: cvs log file name If the used repository has logging enabled, &cervisia; can present you a history of certain events like checkouts, commits, rtags, updates and releases. Choose History from the View menu, and &cervisia; will issue the command cvs history -e -a This fetches the complete logging file from the server, i.e. a list of the events for all users and all modules. This can be a huge amount of data. Now you can see the list of events, sorted by date. In the second column, the type of the event is shown: Checkout - The user who is displayed in the 'Author' column has checked out a module Tag - A user has used the command cvs rtag. Note that the usage of cvs tag (as done by &cervisia;'s AdvancedTag/Branch... command) is not recorded in the history database. This has historical reasons (see the &CVS; FAQ). Release - A user has released a module. Actually, this command is rarely used and not of much value. Update, Deleted - A user has made an update on a file which was deleted in the repository. As a consequence, the file was deleted in his working copy. Update, Copied - A user has made an update on a file. A new version was copied into working copy. Update, Merged - A user has made an update on a file. The modifications in the repository version on the file were merged into his working copy. Update, Conflict - A user has made an update on a file, and a conflict with his own modifications was detected. Commit, Modified - A user committed a modified file. Commit, Added - A user added a file and committed it. Commit, Removed - A user removed a file and committed it.

You can sort the list by other criteria simply by clicking on the respective column header. In order to sort out the history entries you are interested in, there are various filter options activated by check boxes: Show commit events - shows commits Show checkout events - shows checkouts Show tag events - shows taggings Show other events - shows events not included in the above Only user - shows only events caused by a certain user Only file names matching - filters file names by a regular expression Only dirnames matching - filters folder names by a regular expression Special characters recognized by the regular expression matcher are: x* matches any number of occurrences of the character x. x+ matches one or more of occurrences of the character x. x? matches zero or one occurrences of the character x. ^ matches the start of the string. $ matches the end of the string. [a-cx-z] matches a set of characters, ⪚ here the set consisting of a,b,c,x,y,z. Branches of a module are parallel versions of this module. A good real life example of the use of this feature is the release of a software project. After a major release, there are bugs in the code that should be fixed, but people want to add new features to the application too. It is very hard to do both at the same time because new features usually introduce new bugs, making it hard to track down the old ones. To solve this dilemma, &CVS; lets you create a parallel version, that we will call the "stable release branch", where you can only add bugfixes, leaving the main branch (HEAD) open for adding new features. Tags are used to mark a version of a project. &CVS; stamps one version of each file with the tag, so when you checkout or update to a specific tag, you will get always the same file versions; therefore, as opposed to branches, tags are not dynamic: you cannot develop a tag. Tags are useful to mark releases, big changes in the code, &etc; When you are developing or following the development of a software project, you do not necessarily work with the main branch all the time. After a release, you may want to stay with the released branch for a while, to enjoy its relative stability, fix bugs, translate the sources, &etc; To do all that, you have to update to the released branch. All your files will be updated to the latest version of the files in that branch. After updating, all your new commits will be uploaded to the new branch as well. Also, if you want to track a bug that was reported against a past tagged release, &CVS; offers you the possibility to retrieve the software as it was released, by updating to that tag. Besides, if you want to fetch a past version of your project, you can update your working copy to a specific date. This may be useful if an error was introduced in the project between two releases, and you have an opinion on when that was. When you update to a date or tag, the versions of your files will be the same as the versions in that specific date or the versions stamped by that tag. Before updating to a different branch or tag, make sure you committed all your changes to the branch you are working with. If your are not ready to commit your changes, but do not want to discard them, do not update to the new branch, as you may lose your changes. As an alternative, you can do a new checkout, to work in parallel with both versions.

A screenshot of &cervisia;'s update to tag dialog

Update to branch Select this option to update to a branch. Enter the name of the branch in the drop down text box (or press the Fetch List button to retrieve the list of branches from the &CVS; server, and select the one you want in the drop down list). Update to tag Select this option to update to a tag. Enter the name of the tag in the drop down text box (or press the Fetch List button to retrieve the list of tags from the &CVS; server, and select the one you want in the drop down list). Update to date Select this option to update to a date. In the field below, you can enter a wide variety of date formats. One possible format is yyyy-mm-dd where yyyy is the year, mm is the month (numerically) and dd is the day. Alternatives are some English phrases like yesterday or 2 weeks ago. Updating to a tag or date make them 'sticky', &ie; you can not commit further modifications on that files (unless the tag is a branch tag). In order to get back to the main branch, use the menu item AdvancedUpdate to HEAD. The comand issued to update to a branch or tag is: cvs update -r tag The command issued to update to a date is: cvs update -D date The command issued to update to the main branch (HEAD) is: cvs update -A We discuss here only the technical aspects of tagging and branching. If you are only a user, not the administrator of the repository, you will probably not be confronted with the problem. If however you are your own administrator, you should first read about the non-technical problems that accompany branching, in order to get an impression of how time-consuming and error-prone maintaining different branches of a project can be. The appendix includes some references about this topic. Simple tagging is something you usually do when a release is made, so that you can at any time easily get back to the project state at that time. Tags are usually given a name consisting of the project name and the version number. For example, &cervisia; 1.0 is available under the tag CERVISIA_1_0. &cervisia; enforces &CVS;'s strict rules about what constitutes valid tag name. It must begin with a letter and may contain letters, digits, hyphens and underscores. Normally, you will want to tag the whole project (although &CVS; of course allows you to tag only a subset). To this end, mark the toplevel folder in the view and choose AdvancedTag/Branch. Now enter the name of the tag, press Return and you are done. Creating a branch is not significantly more difficult: In the tag dialog, check the box Create branch with this tag. You can also delete an existing tag: Choose AdvancedDelete Tag in the main view. Another aspect of branching is the merging of modifications from a branch to the current branch. If you are going to do this, choose AdvancedMerge.... The dialog that appears now gives you two options: Either you may merge all modifications done on a branch to the current branch. In that case, check the box Merge from branch and fill in the branch you want to merge from. &cervisia; will then execute the command cvs update -j branchtag The other possibility is that you want to merge only the modifications made between two tags on a branch. This usually happens when you merge from the same branch to the trunk several times. In that case, check the box Merge modifications and enter (in the correct order) the two relevant tags. This will result in a command cvs update -j branchtag1 -j branchtag2 A watch is the conventional name for &CVS;'s feature to notify users of the repository whenever a file has been changed or a developer has started editing a file. The usage of watches requires that the file $CVSROOT/CVSROOT/notify has been set up properly. This is not discussed here; if you need further information on the setup from the administrator's point of view, read one of the books listed in the appendix. &cervisia;'s main support of watches are six menu items. In order to add a watch to one or several files, use AdvancedAdd Watch.... In the dialog you get, you can choose to get notified for any of the types of events that &CVS; supports. For example, if you only want to get notified when a file is committed, check the boxes Only and Commits. If you want to get notified about any event related to the marked files, check the box All. The command line used when you accept the dialog is cvs watch add -a commit file names or with a similar option, depending on the events you chose to watch. If you are not interested in some files anymore, you can remove your watches on them. To this end, use AdvancedRemove Watch.... In the dialog you get here, the same options are offered as in the form you filled out when adding the watch. When you confirm this dialog, &cervisia; issues the command cvs watch remove file names possibly with an option -a for the chosen events. Finally, you can get a list of the people who are watching a couple of files. Choose AdvancedShow Watchers. Using this menu item will result in a command cvs watchers file names In the normal usage scenario of &CVS;, each developer works separately in his checked out sandbox. When he wants to modify some file, he can just open it in his editor and start working on it. Nobody else will know about this work until the file gets committed. For some developer groups, this is not the preferred model of cooperation. They want to get notified about someone working on a file as soon as he starts with it. This can be achieved by some further &CVS; commands. Before you start editing a file, select it in &cervisia;'s main window and choose AdvancedEdit. This will execute the command cvs edit file names This will send out a notification to everyone who has set an edit watch on this file. It will also register you as an editor of the file. You can obtain a list of all editors of a certain file by using AdvancedShow Editors. This is equivalent to typing on the command line cvs editors file names An editing session is automatically ended when you commit the affected file. At that moment, an unedit notification gets sent out to all people who have registered a respective watch on the file. Of course, sometimes you may not want to commit the file, but abort the editing session and revert to the previous version of the file. This is done by using AdvancedUnedit. Note that &cervisia; will not ask you for confirmation; that means if you use this menu item, all your work done since you used AdvancedEdit will be lost. Precisely, &cervisia; uses the command line echo y | cvs unedit file names So far, we have only the discussed the case where edits and unedits are used voluntarily be the developers. In addition &CVS; supports a model which enforces the usage of these commands. The responsible command to switch to this model is cvs watch on which we will not explain further because it is mostly used by the administrator of the repository. However, the important point from the developer's point of view is that when the project enforces edits, working copies are checked out readonly. That means you cannot edit a file by default (unless you use tricks like chmod). Only when you use AdvancedEdit, the file becomes writable. It is made read-only again when you commit the file or use AdvancedUnedit. &cervisia;'s editor interface helps you with projects that enforce watches also in a different way. If you just started an editor with a readonly file by double-clicking on it or by using FileEdit, you would not be able to save your modifications later. This has of course a reason: Whenever you want to change a file, you should run cvs edit before, so that all people watching the file get a notification that you are working on it. In such a case, it is advisable to check the option SettingsDo cvs edit Automatically When Necessary. Now, whenever you edit a file by double-clicking it, &cervisia; will run cvs edit before the editor is actually executed. Then you can edit your file as usual. When you have finished your work, commit your files, and the committed files are read-only again. The development model usually followed when &CVS; is used is called unreserved checkouts. Each developer has his own sandbox where he can edit files as he likes. If when the watch features - like cvs edit - are used, multiple developers can work on files synchronously. Changes done by a different developer are merged into the local sandbox when an update is performed. Other revision control systems - like RCS and SourceSafe use a different model. When a developer wants to a edit a file, he has to lock it. Only one developer at a time can a lock a file. When he has finished editing, the lock is released. On the one hand, with this model, conflicts can never happen. On the other hand, two developers can not work on the same file at the same time, even when their changes do not affect each other. This can be a bottleneck. We are not going to discuss the organizational benefits of both approaches. Nevertheless we mention that although &CVS; has some support for locking, it is not the preferred way of working with &CVS;. You should not use these features unless you are sure that your project manager allows them. With &cervisia;, you lock files as follows. Select the desired files in the main view. Then choose AdvancedLock. This runs the command cvs admin -l file names The reverse effect is achieved by using AdvancedUnlock. This runs the command cvs admin -u file names &cervisia; can be customized in various ways to your needs and preferences. Some options which you may want to change regularly are directly available in the Settings menu. Others are united in a common dialog which is available via OptionSettings.... User name for the ChangeLog editor: Whenever you use the menu item FileInsert ChangeLog Entry..., a new ChangeLog entry is generated with the current date and your username. Normally, it is considered good style to insert your full name and your email address into each of your ChangeLog entries. &cervisia; add automatically the full name and email address entered here. Path to cvs executable, or 'cvs': Here you can set the name (or path) to the cvs command line client. By default, the &CVS; executable found in your $PATH is used by &cervisia;. Number of context lines in the diff dialog: For the diff dialog, &cervisia; uses the option -U to diff. This lets diff show only a limited number of lines around each difference region (context lines). Here you can set the argument to -U. Additional options for cvs diff: Here you can add additional arguments to the diff. A popular example is -b which lets diff ignore changes in the amount of whitespace. Tab width in diff dialog: In the diff dialog, tab characters present in your file or in the output of the diff command are expanded into a fixed number of space characters. By default, each tab is replaced by eight spaces, but here you can setup a different number. External diff frontend: When you use any of the features which show the diff dialog, like ViewDifference to Repository..., &cervisia; invokes its internal diff frontend. If you prefer a different one, like Kompare, TkDiff, or xxdiff, enter its file name and path here. When opening a sandbox from a remote repository, start a File->Status command automatically When you check this option, the FileStatus command is started whenever you open a remote sandbox. This command may need some time and also needs a connection to the server for remote repositories (making it unusable for offline usage). When opening a sandbox from a local repository, start a File->Status command automatically When you check this option, the FileStatus command is started whenever you open a local sandbox. Timeout after which a progress dialog appears (in ms): Practically all &CVS; commands started in a sandbox which belongs to a remote repository need a connection to the &CVS; server. This is affected by delays from the network connection or a high load on the server. For this reason, for commands like ViewDifference to Repository... &cervisia; opens a dialog which indicates that the command is still running and which allows you to abort it. Furthermore, this dialog is used to show you error messages from &CVS;. As this dialog may become annoying after some time, it is shown only after a certain timeout which is 4 seconds by default. Here you can change this value. Default compression level: The cvs client compresses files and patches when they are transferred over a network. With the command line option -z, the compression level can be set. You can setup &cervisia; to use this option by configuring the level here. The value set here is used only as a default; additionally there is a per-repository setting available in RepositoryRepositories.... Utilize a running or start a new ssh-agent process Check this box if you use ext (rsh) repositories, the &ssh; remote shell to communicate with the repository and ssh-agent to manage your keys. Font for protocol window... Press this button to open the Set Font dialog, to set the font used in the protocol window (this is the window showing the output of the cvs client). Font for annotate view... Press this button to open the Set Font dialog, to set the font used in the annotate view. Font for diff view... Press this button to open the Set Font dialog, to set the font used in diff dialogs. Colors Press the colored buttons to open the Select Color dialog, to set the color used for Conflict, Local Change, or Remote Change, in the main view or Diff change, Diff insertion, or Diff deletion, in &cervisia;'s built-in diff frontend. Split main window horizontally &cervisia;'s main window is normally split vertically into a window with the file tree above and one with the &CVS; output below; alternatively, you can arrange them horizontally. In its main file tree, &cervisia; does not display all files which are actually there. This is analog to cvs itself and helps to avoid clutter caused by uninteresting stuff like object files. &cervisia; tries to mimic cvs's behavior as close as possible, i.e. it gets ignore lists from the following sources: A static list of entries which includes things like *.o and core. For details, see the &CVS; documentation. The file $HOME/.cvsignore. The environment variable $CVSIGNORE. The .cvsignore file in the respective folder. cvs itself additionally looks up entries in $CVSROOT/CVSROOT/cvsignore, but this is a file on the server, and &cervisia; should be able to start up offline. If you are working with a group that prefers to use an ignore list on the server, it's probably a good idea to take a look which patterns are listed there and to put them into the .cvsignore file in your home folder. &CVS; comes with a complete set of documentation in the form of info pages, known as "The Cederqvist". If it is properly installed, you get browse it by typing in info:/cvs into the locationbar of kdehelp, khelpcenter resp. Alternative, you can just choose HelpCVS Info in &cervisia;. An on-line HTML version of the Cederqvist is available on the web. As this book is maintained together with &CVS;, it is normally the most up-to-date reference; nevertheless, considering other documentation for learning to use &CVS; is recommended, in particular the following. Karl Fogel has written the excellent book Open Source Development with CVS. About half of this book is about the development process of Open Source software. The other half is a technical documentation of &CVS;. Thankfully, the technical part of the book has been made freely redistributable under the GPL, so that you can download a HTML version of it. A list of errata is available on the webpage mentioned above. &CVS; issues are discussed on a dedicated mailing list. There is USENET group comp.software.config-mgmt dedicated to configuration management in general. &CVS; is only marginally a topic in this group, but nevertheless it may be interesting for discussing merits of various revision control systems compared to &CVS;.
