aegis -New_ReLeaSe(1) General Commands Manual aegis -New_ReLeaSe(1) NAME aegis new release - create a new project from an old-style project. SYNOPSIS aegis -New_ReLeaSe project-name [ new-project-name ][ option... ] aegis -New_ReLeaSe -List [ option... ] aegis -New_ReLeaSe -Help DESCRIPTION The aegis -New_ReLeaSe command is used to create a new project from an existing project. It creates a new post-3.0 project from an old pre-3.0 project. Please Note: If your old-style project does not have a version number in the project name, you must supply a new project name, otherwise you will get an error. (If you want to re-use the old project name, you need to rename the old project, and then use aenrls to create a new new-style project with the old name. See the HOWTO for how to change a project's name.) This command was essential before the introduction of branches into the Aegis model. It is more useful to create a new release of a project by ending development on the branch of the previous release and starting development of a new branch numbered for the desired re- lease. Once you have a new-style project, use the aenbr(1) command to create new branches on this project. This provides more efficient release management, and allows historical versions to be reproduced more sim- ply. If no new-project-name is specified, it will be derived from the project given as follows: any minor version dot suffix will be removed from the name, then any major version dot suffix will be removed from the name. A major version dot suffix will be appended, and then a mi- nor version dot suffix will be appended. As an example, "foo.1.0" would become "foo.1.1" assuming the default minor version increment, and "foo" would become "foo.1.1" assuming the same minor version in- crement. The entire project baseline will be copied. The project state will be as if change 1 had already been integrated, naming every file (in the old project) as a new file. The history files will reflect this. No build will be necessary; it is assumed that the old baseline was built successfully. Change numbers will commence at 2, as will build num- bers. Test numbers will commence where the old project left off (be- cause all the earlier test numbers were used by the old project). The default is for the minor version number to be incremented. If the major version number is incremented or set, the minor version number will be set to zero if it is not explicitly given. The pointer to the new project will be added to the first element of the search path, or /usr/local/com if none is set. If this is inap- propriate, use the -LIBrary option to explicitly set the desired loca- tion. See the -LIBrary option for more information. The project directory, under which the project baseline and history and state and change data are kept, will be created at this time. If the -DIRectory option is not given, the project directory will be cre- ated in the directory specified by the default_project_directory field of the project user's aeuconf(5), or if not set in project user's home directory; in either case with the same name as the project. All staff will be copied from the old project to the new project with- out change, as will all of the project attributes. THE BASELINE LOCK The baseline lock is used to ensure that the baseline remains in a consistent state for the duration of commands which need to read the contents of files in the baseline. The commands which require the baseline to be consistent (these in- clude the aeb(1), aecp(1) and aed(1) commands) take a baseline read lock. This is a non-exclusive lock, so the concurrent development of changes is not hindered. The command which modifies the baseline, aeipass(1), takes a baseline write lock. This is an exclusive lock, forcing aeipass(1) to block until there are no active baseline read locks. It is possible that one of the above development commands will block until an in-progress aegis -Integrate_PASS completes. This is usually of short duration while the project history is updated. The delay is essential so that these commands receive a consistent view of the baseline. No other integration command will cause the above develop- ment commands to block. When aegis' branch functionality is in use, a read (non-exclusive) lock is taken on the branch baseline and also each of the "parent" baselines. However, a baseline write (exclusive) lock is only taken on the branch baseline; the "parent" baselines are only read (non-ex- clusive) locked. Project Directory Location Please Note: Aegis also consults the underlying file system, to deter- mine its notion of maximum file size. Where the file system's maximum file size is less than maximum_filename_length, the filesystem wins. This can happen, for example, when you are using the Linux UMSDOS file system, or when you have an NFS mounted an ancient V7 filesystem. Setting maximum_filename_length to 255 in these cases does not alter the fact that the underlying file systems limits are far smaller (12 and 14, respectively). If your development directories (or your whole project) is on filesys- tems with filename limitations, or a portion of the heterogeneous builds take place in such an environment, it helps to tell Aegis what they are (using the project config file's fields) so that you don't run into the situation where the project builds on the more permissive environments, but fails with mysterious errors in the more limited en- vironments. If your development directories are routinely on a Linux UMSDOS filesystem, you would probably be better off setting dos_filename_re- quired = true, and also changing the development_directory_template field. Heterogeneous development with various Windows environments may also require this. OPTIONS The following options are understood: -DIRectory path This option may be used to specify which directory is to be used. It is an error if the current user does not have appro- priate permissions to create the directory path given. This must be an absolute path. Caution: If you are using an automounter do not use `pwd` to make an absolute path, it usually gives the wrong answer. -Help This option may be used to obtain more information about how to use the aegis program. -LIBrary abspath This option may be used to specify a directory to be searched for global state files and user state files. (See aegstate(5) and aeustate(5) for more information.) Several library op- tions may be present on the command line, and are search in the order given. Appended to this explicit search path are the directories specified by the AEGIS_PATH environment vari- able (colon separated), and finally, /usr/local/lib/aegis is always searched. All paths specified, either on the command line or in the AEGIS_PATH environment variable, must be ab- solute. -List This option may be used to obtain a list of suitable subjects for this command. The list may be more general than expected. -Not_Logging This option may be used to disable the automatic logging of output and errors to a file. This is often useful when sev- eral aegis commands are combined in a shell script. -TERse This option may be used to cause listings to produce the bare minimum of information. It is usually useful for shell scripts. -Verbose This option may be used to cause aegis to produce more output. By default aegis only produces output on errors. When used with the -List option this option causes column headings to be added. -VERSion number This option may be used to specify the version number for the project. Version number are implemented as branches. Use the empty string as the argument if you want no version branches created. -Wait This option may be used to require Aegis commands to wait for access locks, if they cannot be obtained immediately. De- faults to the user's lock_wait_preference if not specified, see aeuconf(5) for more information. -No_Wait This option may be used to require Aegis commands to emit a fatal error if access locks cannot be obtained immediately. Defaults to the user's lock_wait_preference if not specified, see aeuconf(5) for more information. See also aegis(1) for options common to all aegis commands. All options may be abbreviated; the abbreviation is documented as the upper case letters, all lower case letters and underscores (_) are op- tional. You must use consecutive sequences of optional letters. All options are case insensitive, you may type them in upper case or lower case or a combination of both, case is not important. For example: the arguments "-project", "-PROJ" and "-p" are all inter- preted to mean the -Project option. The argument "-prj" will not be understood, because consecutive optional characters were not supplied. Options and other command line arguments may be mixed arbitrarily on the command line, after the function selectors. The GNU long option names are understood. Since all option names for aegis are long, this means ignoring the extra leading '-'. The "--op- tion=value" convention is also understood. RECOMMENDED ALIAS The recommended alias for this command is csh% alias aenrls 'aegis -nrls \!* -v' sh$ aenrls(){aegis -nrls "$@" -v} ERRORS It is an error if the old project named does not exist. It is an error if the old project named has not yet had any changes integrated. It is an error if the old project named has any changes not in the completed state. It is an error if the current user is not an administrator of the old project. EXIT STATUS The aegis command will exit with a status of 1 on any error. The aegis command will only exit with a status of 0 if there are no er- rors. ENVIRONMENT VARIABLES See aegis(1) for a list of environment variables which may affect this command. See aepconf(5) for the project configuration file's project_specific field for how to set environment variables for all commands executed by Aegis.
