-New_ReLeaSe -Help

The -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 release.

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 simply.

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 minor 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 increment.

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 numbers. Test numbers will commence where the old project left off (because 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 if none is set. If this is inappropriate, use the -LIBrary option to explicitly set the desired location. 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 created 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 without change, as will all of the project attributes.

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 include 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 -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 development commands to block.

When ' 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-exclusive) locked.

Project Directory Location

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 appropriate 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 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 options 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 variable (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 absolute.

-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 several 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 to produce more output. By default 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 commands to wait for access locks, if they cannot be obtained immediately. Defaults 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 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.

All options may be abbreviated; the abbreviation is documented as the upper case letters, all lower case letters and underscores (_) are optional. 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 interpreted 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 are long, this means ignoring the extra leading '-'. The "--option=value" convention is also understood.

The recommended alias for this command is

csh%	alias aenrls ' -nrls \!* -v'
sh$	aenrls(){ -nrls "$@" -v}

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.

The command will exit with a status of 1 on any error. The command will only exit with a status of 0 if there are no errors.

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.
