        aegis integrate pass - pass a change integration


        aegis -Integrate_Pass [ option...  ]
        aegis -Integrate_Pass -List [ option...  ]
        aegis -Integrate_Pass -Help


        The aegis -Integrate_Pass command is used to notify aegis that a change has passed
        integration.  The change is advanced from the being integrated state to the completed
        state.  boxwid = 1 down box "being" "integrated" arrow " integrate" ljust " pass" ljust
        box "completed"

        This command updates the file histories, so that future aecp(1) commands may extract
        previous file versions from history, and so that future aed(1) commands may merge out-of-
        date files.  The history is updated using the history_create_command and
        history_put_command fields of the project configuration file (see aepconf(5) for more
        information).  The integrate pass will abort with an error if one of these history
        commands should fail, e.g. by running out of disk space.  If this should happen, the
        change will remain in the being integrated state, and the integration directory is

        Once the history has been updated, the integration directory is renamed as the baseline
        directory, and the old baseline directory is deleted.

        Once integrate pass is complete the change is no longer assigned to the current user.

   History Tools Modify Files
        Many history tools (e.g. RCS and SCCS) can modify the contents of the file when it is
        committed.  This usually requires the use of specific “keyword” strings, and there are
        usually options to turn this behavior off, but users familiar with version control tools
        (as opposed to configuration management systems) will often use these features.  The
        problem is that if the commit changes the file, the source file in the repository now no
        longer matches the object file in the repository.  I.e.  the history tool has compromised
        the referential integrity of the repository.  By default, a fatal error is emitted if the
        file is changed by the check-in, however this can be modified to a be warning or even
        ignored completely; see the history_put_trashes_file field of aepconf(5) for more

   File Modification Times
        The modification times of all files modified since the beginning of integration (see
        aeib(1) for more information) are updated to be since the beginning of integrate pass.
        The order of modification times will be preserved, however the time range will be
        compressed to the greatest extent possible.  This ensures that subsequent development
        builds will notice that baseline files have changed.

        Note that if there are many new files with all different timestamps in the integration
        directory, and if the number of files with different timestamps exceeds the number of
        seconds since the start of the integrate-pass command, Aegis may have to set file
        modification times into the future.

        The build_time_adjust field of the project config file controls Aegis' behavior in this
        case.  (See aepconf(5) for more information.)  There are three settings:

                This setting, which is the default, causes Aegis to sleep until the file
                modification times would no longer be in the future.  This avoids both
                development build problems and integration build problems, both of which which
                can arise as a result "interesting" file modification times.

                Aegis will issue a warning that the file modification times extend into the
                future, but will not sleep.  This may cause integration build problems,
                particularly if you are using aeintegratq(1).  Development builds may perform
                redundant builds, however aet -reg should not produce false negatives.

                This is highly inadvisable.  It is provided solely for some very rare
                circumstances.  This setting causes Aegis not to adjust the file modification
                times at all.  This can have very unhappy side-effects, especially of the
                integration build was before one or more development builds; the commonest
                symptom being that development builds do not always cause a relink of the
                necessary executables, and aet -reg may give false negatives.  It is strongly
                recommended that you do not use this setting.

        If you use cook(1), see the time-adjust-back flag for how to compress the time range even
        further.  This usually makes the sleep (or the warning period) significantly shorter.

        On successful completion of this command, after the directory rename has ocurred and
        after the database has been updated, the integration_pass_notify_command field of the
        project attributes is run, if set.  See aepattr(5) and aepa(1) for more information.
        This command is run as the project owner.

        Some compilers bury absolute path names into object files and executables.  The renaming
        of the integration directory to become the new baseline breaks these paths.  The above
        command is passed an environment variable called AEGIS_INTEGRATION_DIRECTORY so that the
        appropriate symlink may be placed, if desired.

        Other commands run by this command include the history_create_command, history_put_‐
        command and history_query_command fields of the project config file.  See aepconf(5) for
        more information.


        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

        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.

   The History Lock
        Where a project has a number of branches active simultaneously, it is possible for
        independent integrate pass commands for different branches to be issued very close
        together.  The is an exclusive history lock taken by integrate pass to ensure that only
        one branch is updating the file history at a time, thus preventing history file


        The “aegis -Test -SUGgest” command may be used to have aegis suggest suitable regression
        tests for your change, based on the source files in your change.  This automatically
        focuses testing effort to relevant tests, reducing the number of regression tests
        necessary to be confident that you have not introduced a bug.

        The test correlations are generated by the “aegis -Integrate_Pass” command, which
        associates each test in the change with each source file in the change.  Thus, each
        source file accumulates a list of tests which have been associated with it in the past.
        This is not as exact as code coverage analysis, but is a reasonable approximation in

        The aecp(1) and aenf(1) commands are used to associate files with a change.  While they
        do not actively perform the association, these are the files used by aeipass(1) and
        aet(1) to determine which source files are associated with which tests.

   Test Correlation Accuracy
        Assuming that the testing correlations are accurate and that the tests are evenly
        distributed across the function space, there will be a less than 1/number chance that a
        relevant test has not been run by the “aegis -Test -SUGgest number” command.  A small
        amount of noise is added to the test weighting, so that unexpected things are sometimes
        tested, and the same tests are not run every time.

        Test correlation accuracy can be improved by ensuring that:

        · Each change should be strongly focused, with no gratuitous file inclusions.  This
          avoids spurious correlations.

        · Each item of new functionality should be added in an individual change, rather than
          several together.  This strongly correlates tests with functionality.

        · Each bug should be fixed in an individual change, rather than several together.  This
          strongly correlates tests with functionality.

        · Test correlations will be lost if files are moved.  This is because correlations are by

        The best way for tests to correlate accurately with source files is when a change
        contains a test and exactly those files relating to the functionality under test.  Too
        many spurious files will weaken the usefulness of the testing correlations.


        Aegis is capable of recording metrics as part of the file attributes of a change.  This
        allows various properties of files to be recorded for later trend analysis, or other

        The specific metrics are not dictated by Aegis.  It is expected that the integration
        build will create a metrics file for each of the source files the change.  These metrics
        files must be in the format specified by aemetrics(5).

        The name of the metrics file defaults to “filename,S”, however it may be varied, by
        setting the metrics_filename_pattern field of the project config file.  See aepconf(5)
        for more information.

        If such a metrics file exists, for each source file in a change, it will be read and
        remembered at integrate pass time.  If it does not exist, Aegis assumes there are no
        relevant metrics for that file, and proceeds silently; it is not an error.


        The following options are understood:

        -Change number
                This option may be used to specify a particular change within a project.  See
                aegis(1) for a complete description of this option.

                This option may be used to obtain more information about how to use the aegis

                This option may be used to obtain a list of suitable subjects for this command.
                The list may be more general than expected.

                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

        -Project name
                This option may be used to select the project of interest.  When no -Project
                option is specified, the AEGIS_PROJECT environment variable is consulted.  If
                that does not exist, the user's $HOME/.aegisrc file is examined for a default
                project field (see aeuconf(5) for more information).  If that does not exist,
                when the user is only working on changes within a single project, the project
                name defaults to that project.  Otherwise, it is an error.

        -REAson text
                This option may be used to attach a comment to the change history generated by
                this command.  You will need to use quotes to insulate the spaces from the shell.

                This option may be used to cause listings to produce the bare minimum of
                information.  It is usually useful for shell scripts.

                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.

        -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.

                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


        The recommended alias for this command is
        csh%    alias aeipass 'aegis -ipass \!* -v'
        sh$     aeipass(){aegis -ipass "$@" -v}


        It is an error if the change is not assigned to the current user.
        It is an error if The change is not in the being integrated state.
        It is an error if there has been no successful 'aegis -Build' command for the
        It is an error if there has been no successful 'aegis -Test' command for the integration.
        It is an error if there has been no successful 'aegis -Test -BaseLine' command for the


        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.
