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 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 /var/lib/aegis
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
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 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 development 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-exclusive) locked.
Project Directory Location
Please Note: Aegis also consults the underlying file system, to determine 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 filesystems 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
environments.
If your development directories are routinely on a Linux UMSDOS filesystem, you would probably be better
off setting dos_filename_required = 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 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 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 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 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. 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 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 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 aegis are long, this means
ignoring the extra leading '-'. The "--option=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 errors.
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.
