NAME
aepconf - aegis project configuration file
SYNOPSIS
project/baseline/aegis.conf (default)
project/baseline/config (obsolete)
DESCRIPTION
A project configuration file is used to store information about a
project. This file is under source control, and is one of the
project’s source files. Developers may thus modify this file as part
of a change.
As of aegis.4.17, it is possible to assign any arbitrary name to the
project configuration file or files. See aenf(1) for more information.
This file contains a number of commands to be executed by Aegis. There
are times when the substitutions in these commands may contain shell
special characters, which would change the meaning of the commands in
unintended ways. There are two main sources of these problems: file
names and architecture names. In order to have shell special
characters in filenames, you must set the shell_safe_filenames field
(see below) to false. If you do this, you will need to use the quote
substitution (see aesub(5)) to quote them, so that the shell does not
abuse them. Other things which may need quoting include architecture
names if you get creative, and edit numbers if unusual ones are
generated by your history tool.
Getting Started
Because the project aegis.conf file is under source control like any
other file, you must create the project aegis.conf file in the very
first change of your project. Use the
$ aenf aegis.conf
$
command and then editing the file to fill in the fields. Subsequent
Aegis commands in that change will use that file. Once the change is
completed (see aeipass(1) for more information) the file will be
present in the baseline, and be used by all users and all changes.
If you ever need to change one of the fields of the project aegis.conf
file, you do this the same way as for any other source file, by copying
it into a change using the
$ aecp aegis.conf
$
command and then edit the file to make the desired changes. While it’s
being developed your change will use it’s copy of the project
aegis.conf file, but once the change is completed (see aeipass(1) for
more information), it becomes the new version used by all users and
changes.
If you would prefer a different name for the project configuration
file, use the aenf -config option. For example, the
$ aenf -config project.configuration
$
command would create a file called project.configuration and Aegis
would then proceed to use it to obtain project configuration
information for the duration of the project. This attribute will even
be preserved across file renames (see the aemv(1) command).
CONTENTS
This file contains the following fields:
configuration_directory = string;
This field names a directory which will be searched for
additional configuration files. (This directive is only legal
or meaningful in the master project aegis.conf file.)
All source files (change source files and project source files)
present in this directory will be read in as if they were added
to the end of the project "aegis.conf" file.
The usual priority of files (development directory, branch
baseline, etc, project trunk baseline) is observed when these
files are read.
Please note that the physical directories are never searched,
only the Aegis concept of the change and project files is
consulted (i.e. files created and modified in the usual way
with aenf(1) and aecp(1) commands). Placing additional files
in the physical directories will have no effect.
It is recommended that if you use this field at all, that your
top level project aegis.conf file should only contain this one
field. This is to avoid overly-large re-reading of this file
when it is joined to all the others.
build_command = string;
This field describes how to build the project (actually, how to
do an integration build). This field is mandatory. Used by
the aeb(1) command. All of the substitutions described by
aesub(5) are available.
Executed as: the integrator (for integration builds) or the
developer (for development builds). Current directory: the
integration directory of the change (for integration builds)
the development directory of the change (for development
builds). Exit status: zero is considered success, non-zero is
a failure and a subsequent successful (exit zero) build will be
required.
If this field is set to "exit 0" then no integration build will
be required, and will not be checked for by the aeipass(1)
command.
development_build_command = string;
This field describes how to do a development build. If this
field is absent, it defaults to the above. Used by the aeb(1)
command. All of the substitutions described by aesub(5) are
available.
Executed as: the developer. Current directory: the development
directory of the change. Exit status: zero is considered
success, non-zero is a failure and a subsequent successful
(exit zero) build will be required.
If this field is set to "exit 0" then no development build will
be required, and will not be checked for by the aede(1)
command.
development_directory_style = { ... };
This field encapsulates a set of parameters controlling the
appearance of the development directory. It has significant
implications for the way the DMT is used, and the directory
appearance presented to the DMT.
source_file_link = boolean;
This field is true if hard links are to be used for
project source files (which are not part of the change)
so that the work area has a complete set of source
files.
Defaults to false if not set.
If the host system does not have hard links, this field
will be ignored.
Maintaining the hard links can be time consuming for
large projects, and add quite a noticeable delay before
builds start doing anything. If possible, change your
build system to use the $search_path substitution
instead and avoid links.
source_file_symlink = boolean;
This field is true if symbolic links are to be used for
project source files (which are not part of the change)
so that the work area has a complete set of source
files.
Defaults to false if not set. [If the obsolete
create_symlinks_before_build field is set, defaults to
the value of that field, with a warning.]
If (source_file_link == true and hard links are
available) this field will be ignored. If the host
system does not have symbolic links, this field will be
ignored.
Maintaining the symbolic links can be time consuming
for large projects, and add quite a noticeable delay
before builds start doing anything. If possible,
change your build system to use the $search_path
substitution instead and avoid symbolic links.
source_file_copy = boolean;
This field is true if copies are to be used for project
source files (which are not part of the change) so that
the work area has a complete set of source files. File
modification time attributes will be preserved.
Defaults to false if not set.
If ((source_file_link == true and hard links are
available) OR (source_file_symlink == true and symbolic
links are available)) this field will be ignored.
Maintaining the copies can be time consuming (and space
consuming) for large projects, and add quite a
noticeable delay before builds start doing anything.
If possible, change your build system to use the
$search_path substitution instead and avoid file
copies.
source_file_whiteout = boolean;
The source_file_whiteout field mat be used to specify
the presence (true) or absence (false) of white-out
files, used to "cover up" files being removed by a
change set. These files contain 1kB of random data,
intended to cause a syntax error should be build
reference them.
It is rarely necessary to explicitly set this field.
It defaults to false if you set any of the
source_file_link, source_file_symlink or
source_file_copy to true; it defaults to true only if
none of them are true.
Not meaningful (always false) for integration builds.
derived_file_link = boolean;
This field is true if hard links are to be used for
non-source files which are present in the project
baseline(s) but which are not present in the work area,
so that the work area has a complete set of derived
files. This allows work areas to take advantage of
"precompiled" object files (etc) in the baseline(s).
Defaults to false if not set.
If the host system does not have hard links, this field
will be ignored.
Maintaining the links can be time consuming for large
projects, and add quite a noticeable delay before
builds start doing anything. If possible, change your
build system to use the $search_path substitution
instead and avoid hard links. Alternatively, set
derived_at_start_only = true; and your work area will
get a "head start" but the derived files will not be
checked for every build, but this will occasionally
result in long build times after integrations.
See also the integrate_begin_exceptions and symlink_
exceptions fields (they apply to hard links as well as
symbolic links).
derived_file_symlink = boolean;
This field is true if symbolic links are to be used for
non-source files which are present in the project
baseline(s) but which are not present in the work area,
so that the work area has a complete set of derived
files. This allows work areas to take advantage of
"precompiled" object files (etc) in the baseline(s).
Defaults to false if not set. [If the obsolete
create_symlinks_before_build field is set, defaults to
the value of that field, with a warning.]
If (derived_file_link == true and hard links are
available) this field will be ignored. If the host
system does not have symbolic links, this field will be
ignored.
Maintaining the symbolic links can be time consuming
for large projects, and add quite a noticeable delay
before builds start doing anything. If possible,
change your build system to use the $search_path
substitution instead and avoid symbolic links.
Alternatively, set derived_at_start_only = true; and
your work area will get a "head start" but the derived
files will not be checked for every build, occasionally
resulting in long build times after integrations.
See also the integrate_begin_exceptions and symlink_
exceptions fields.
derived_file_copy = boolean;
This field is true if copies are to be used for non-
source files which are present in the project
baseline(s) but which are not present in the work area,
so that the work area has a complete set of derived
files. This allows work areas to take advantage of
"precompiled" object files (etc) in the baseline(s).
Defaults to false if not set.
If ((derived_file_link == true and hard links are
available) or (derived_file_symlink == true and
symbolic links are available)) this field will be
ignored.
Maintaining the copies can be time consuming (and space
consuming) for large projects, and add quite a
noticeable delay before builds start doing anything.
If possible, change your build system to use the
$search_path substitution instead and avoid symbolic
links. Alternatively, set derived_at_start_only =
true; and your work area will get a "head start" but
the derived files will not be checked for every build,
occasionally resulting in long build times after
integrations.
See also the integrate_begin_exceptions and
symlink_exceptions fields (they apply to copies as well
as symbolic links).
during_build_only = boolean;
This field is set to true if you want the symbolic
links, hard links and/or copies removed again after
each build. This allows the user to maintain the
illusion of using a search path, without actually doing
so. This option is not especially efficient.
Defaults to false if not set. [If the obsolete
remove_symlinks_after_build field is set, defaults to
the value of that field, with a warning.]
If this field is false, the development directory will
be populated by the develop begin (aedb) command, and
the integration directory will be populated by the
integrate begin (aeib) command.
derived_at_start_only = boolean;
This field controls whether the above fields
controlling the appearance of derived files are acted
upon before every build (false) or only when the work
area is created (true).
Defaults to false if not set.
This field is ignored if the during_build_only field is
true.
This field can be complex. Here are a few examples; but much,
much more is possible. The first example will get you a
development directory very similar to one presented by CVS:
development_directory_style =
{
source_file_copy = true;
};
Note that this is hugely space inefficient, and can be quite
slow. The second example will get you a development directory
very similar to one presented by Tom Lord’s arch:
development_directory_style =
{
source_file_link = true;
source_file_symlink = true;
source_file_copy = true;
};
Ideally, however, you should use the $search_path substitution
of the build_command field. This is because the view path
scales better than any other method. On the other hand, you
need a DMT with an excellent view path implementation (and GNU
make doesn’t).
integration_directory_style = { ... };
This field encapsulates a set of parameters controlling the
appearance of the integration directory. It has significant
implications for the way the DMT is used, and the directory
appearance presented to the DMT.
Defaults to the value of the development_directory_style field
if not set. Note that the obsolete create_symlinks_before_
integration_build and remove_symlinks_after_integration_build
fields affect this default (with a warning) but only if they
are explicitly set.
Note that the link_integration_directory field is still
relevant. That field controls how the baseline is cloned to
form the integration directory. This field operates after that
operation.
build_time_adjust_notify_command = string;
This command is run when Aegis adjusts the last-time-modified
time-stamp on files in the integration directory. If the build
tool uses additional information to supplement file
modification times, this command gives you the opportunity to
re-sync the associated database.
Executed as: the project owner.
Current directory: the integration directory. This is what is
about to be come the new baseline.
Exit status: NOT ignored. Note that a failure here puts the
change in a partial state from which recovery may be difficult.
Best to define this command with a set+e so that errors are
ignored at the command level.
build_covers_all_architectures = boolean;
This field is set to true if the build command, when executed
on any architecture, results in all architectures being built.
This may be accomplished, for example, by using cross-
compilation techniques, or Cook’s ability to nominate hosts on
which to execute each build rule.
test_covers_all_architectures = boolean;
This field is set to true if the test command, when executed on
any architecture, results in all architectures being tested.
This may be accomplished, for example, by using Cook’s ability
to nominate hosts on which to execute each test rule.
symlink_exceptions = [ string ];
This field is used to list filename patterns for which symbolic
links must not be made between the development directory and
the baseline. These are usually state files for various tools.
The patterns are matched against the whole filename; naming
only the last filename path element will not work (unless the
pattern starts with “*”).
change_file_command = string;
This field contains a command to be executed whenever a ´aegis
-CoPy_file´, ´aegis -New_File´ ´aegis -New_Test´ ´aegis
-MoVe_file´ or ´aegis -ReMove_file´ command is successful. See
also command-specific overrides. If this field is absent,
nothing is done. Used by the aecp(1), aenv(1), aenf(1),
aerm(1), and aemv(1) commands. All of the substitutions
described by aesub(5) are available; in addition,
${File_List}

In addition:
${File_List}

Executed as: the developer Current directory: the development
directory of the change Exit status: ignored
project_file_command = string;
This field contains a command to be executed during a
development build before the development build command above,
when (a) it is the first build after a develop begin, or (b)
some other change has been integrated into the baseline since
the last build. If this field is absent, nothing is done.
Used by the aeb(1) command. All of the substitutions described
by aesub(5) are available.
develop_begin_command = string;
This field contains a command to be executed whenever a ’aegis
-Develop_Begin’ command is successful. If this field is
absent, nothing is done. Used by the aedb(1) command. All of
the substitutions described by aesub(5) are available.
Executed as: the developer. Current directory: the development
directory of the change. Exit status: ignored.
develop_begin_undo_command = string;
This field contains a command to be executed whenever a ’aegis
-Develop_Begin_Undo’ command is successful. If this field is
absent, nothing is done. Used by the aedbu(1) command. All of
the substitutions described by aesub(5) are available.
Executed as: the developer. Current directory: wherever the
command was executed from. Exit status: ignored.
integrate_begin_command = string;
This field contains a command to be executed whenever a ’aegis
-Integrate_Begin’ command is successful. If this field is
absent, nothing is done. Used by the aeib(1) command. All of
the substitutions described by aesub(5) are available.
Executed as: the project owner. Current directory: the
integration directory. Exit status: ignored.
link_integration_directory = boolean;
This flag is true if Aegis should link the files from the
baseline into the integration directory, rather than copy them
(the default). This has risks, as the build script (e.g.
Howto.cook or Makefile, etc) must unlink targets before
rebuilding them; if this is not done the baseline will be
corrupted. Used by the aeib(1) command.
integrate_begin_exceptions = [ string ];
This field may be used to specify a list of file names (and
file name patterns) which are to be omitted from the copy
(link) of the baseline when creating the integration directory.
Used by the aeib(1) command. This field only applies to
derived files, it does not apply to source files. The patterns
are matched against the whole filename; naming only the last
filename path element will not work (unless the pattern starts
with “*”).
history_create_command = string;
This field is used to create a new history. The command is
always executed as the project owner. Used by the aeipass(1)
command.
It is strongly recommended that the history_create_command and
history_put_command fields are identical. If not set, the
history_create_command field defaults to the same value as the
history_put_command field.
All of the substitutions described by aesub(5) are available;
in addition,
${Input}
Absolute path of the source file.
${History}
Absolute path of the history file. This may need to be
reworked with the Dirname and Basename substitutions to
yield a string suitable for the history tool in
question.
${File_Name}
The base relative file name of the file for this check-
in. Note that the file name can vary over the lifetime
of the file as it is renamed, but the history file name
(above) never varies. Do not use this as the name of
the history file. (Optional)
${UUID} The universally unique identifier of the source file.
This is invariant for the lifetime of the file. Do not
use use this as the name of the history file.
(Optional)
See also the history_put_trashes_file field, below.
Executed as: the project owner. Current directory: the base of
the history tree. Exit status: zero indicates success, all
non-zero exits indicate failure (the integrate pass will fail).
history_get_command = string;
This field is used to get a file from history. The command may
be executed by developers. Used by the aeipass(1) and aecp(1)
commands. All of the substitutions described by aesub(5) are
available; in addition,
${History}
The absolute path of the history file. This may need
to be reworked with the Dirname and Basename
substitutions to yield a string suitable for the
history tool in question.
${Edit}
The edit number to be extracted. It may be an
arbitrary string, varying on the particular history
tool.
${Output}
The absolute path of the destination file.
Executed as: the developer (or the executing user, in the case
of the -independent option). Current directory: the base of
the history tree Exit status: zero indicates success, all non-
zero exits indicate failure (the aecp will fail).
history_put_command = string;
This field is used to add a new change to the history. The
command is always executed as the project owner. Used by the
aeipass(1) command.
It is strongly recommended that the history_put_command and
history_create__command fields are identical. If not set, the
history_put_command field defaults to the same value as the
history_create_command field.
All of the substitutions described by aesub(5) are available;
in addition,
${Input}
The absolute path of the source file.
${History}
The absolute path of the history file. This may need
to be reworked with the Dirname and Basename
substitutions to yield a string suitable for the
history tool in question.
${File_Name}
The base relative file name of the file for this check-
in. Note that the file name can vary over the lifetime
of the file as it is renamed, but the history file name
(above) never varies. Do not use this as the name of
the history file. (Optional)
${UUID} The universally unique identifier of the source file.
This is invariant for the lifetime of the file. Do not
use use this as the name of the history file.
(Optional)
See also the history_put_trashes_file field, below.
Executed as: the project owner. Current directory: the base of
the history tree. Exit status: zero indicates success, all
non-zero exits indicate failure (the integrate pass will fail).
history_transaction_begin_command = string;
The history_transaction_begin_command field is used to specify
a command to be run by aeipass(1) before any history create or
history put commands are run. The default is to do nothing.
All of the substitutions described in aesub(5) are available.
If you need a transaction ID, use the $version substitution.
Executed as: the project owner. Current directory: the base of
the history tree. Exit status: zero indicates success, all
non-zero exits indicate failure (the integrate pass will fail).
history_transaction_end_command = string;
The history_transaction_end_command field is used to specify a
command to be run by aeipass(1) after any history create or
history put commands are run, but before any history query
commands are run. The default is to do nothing.
All of the substitutions described in aesub(5) are available.
If you need a transaction ID, use the $version substitution.
Executed as: the project owner. Current directory: the base of
the history tree. Exit status: zero indicates success, all
non-zero exits indicate failure (the integrate pass will fail).
history_transaction_abort_command = string;
The history_transaction_abort_command field is used to specify
a command to be run by aeipass(1) to indicate that a
transaction has been abandoned. The default is to do nothing.
All of the substitutions described in aesub(5) are available.
If you need a transaction ID, use the $version substitution.
Executed as: the project owner. Current directory: the base of
the history tree. Exit status: ignored (the integrate pass has
already failed).
history_query_command = string;
This field is used to query the topmost edit of a history file.
Result to be printed on the standard output. This command may
be executed by developers. Used by the aeipass(1) and aecp(1)
commands. All of the substitutions described by aesub(5) are
available; in addition,
${History}
The absolute path of the history file. This may need
to be reworked with the Dirname and Basename
substitutions to yield a string suitable for the
history tool in question.
Executed as: the project owner. Current directory: the base of
the history tree. Exit status: zero indicates success, all
non-zero exits indicate failure (the integrate pass will fail).
history_label_command = string;
This field contains a command to be executed whenever a
aeipass(1) or aedn(1) command is successful. This command is
invoked for every file in the project. So using it incurs a
performance penalty. If this field is absent, nothing is done.
All of the substitutions described by aesub(5) are available;
in addition,
${History}
The absolute path of the history file.
${Edit}
The edit number to be labeled. It may be an arbitrary
string, varying on the particular history tool.
${Label}
The label to be attached to the history. When
executed from aeipass(1) this value is the same as
${Version}, which may need to be reworked with the
${Subst} substitutions to yield a string suitable for
the history tool in question. When executed from
aedn(1) it is set to the value passed in from the
command line.
Executed as: the project owner. Current directory: the base of
the history tree. Exit status: zero indicates success, all
non-zero exits indicate failure (a warning will be issued).
Labeling does not scale, so the use of this command is not
encouraged. If you have a project with 10,000 files, and a
change modified exactly one of them, only one history_put_
command execution is required, which operates on one history
file. If you have labeling turned on, it will also be
necessary to execute 10,000 history_label_commands, to add
information Aegis will never use.
history_put_trashes_file = (fatal, warn, ignore);
Many history tools (e.g. RCS) can modify the contents of the
file when it is committed. While there are usually options to
turn this off, they are seldom used. The problem is: if the
commit changes the file, the source 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.
fatal
Emit a fatal error if one or more source files are modified
by a history_put_command or history_create_command. This
is the default.
warn
Emit a warning if a source file is modified.
ignore
Ignore a source file changing. You sure better hope it was

history_content_limitation = (ascii_text, international_text,
binary_capable);
This field describes the content style which the history tool
is capable of working with.
ascii_text
The history tool can only cope with files which contain
printable ASCII characters, plus space, tab and
newline. The file must end with a newline. This is
the default.
international_text
The history tool can only cope with files which do not
contain the NUL character. The file must end with a
newline.
binary_capable
The history tool can cope with all files without any
limitation on the form of the contents.
When a file is added to the history (by either the history_
create_command or the history_put_command field) it is examined
for conformance to this limitation. If there is a problem, the
file is encoded in either quoted printable for MIME64,
whichever is smaller, before being given to the history tool.
This encoding is transparent, the file in the baseline is
unchanged.
On extract (the history_get_command field) the encoding is
reversed, using information attached to the change file
information. This is because each put could use a different
encoding (although in practice, file contents rarely change
that dramatically, and the same encoding is likely to be
deduced every time).
Please note that this field does not apply to the diff_command
or merge_command fields.
diff_command = string;
This field is used to difference of 2 files. The command is
always executed by developers. Used by the aed(1) command.
All of the substitutions described by aesub(5) are available;
in addition,
${ORiginal}
The absolute path of the original file copied into the
change. Usually in the baseline, but not always.
${Input}
The absolute path of the file in the development
directory.
${Output}
The absolute path of the file in which to write the
difference listing.
Executed as: the project owner (for integration diffs), or the
developer (for development diffs). Current directory: the
integration directory (for integration diffs), or the
development directory (for development diffs). Exit status:
zero indicates success, all non-zero exits indicate failure
(the aed will fail).
Note: It is possible to configure a project to omit the diff
step as unnecessary, by the following setting:
diff_command = "exit 0";
This disables all generation, checking and validation of
difference file for each change source file. The merge
functions of the aediff(1) command are unaffected by this
setting.
merge_command = string;
This field is used to merge two competing edits to a file. The
command is always executed by developers. The current
directory will be the development directory. This field is
used by the aed(1) command. All of the substitutions described
by aesub(5) are available; in addition,
${ORiginal}
The absolute path of the original file copied into the
change. Usually not in the baseline, often a temporary
file.
${Most_Recent}
The absolute path of the competing edit, usually in the
baseline.
${Input}
The absolute path of the file in the development
directory. This is the “preferred” edit, if the tool
has this concept when highlighting conflicting edits.
${Output}
The absolute path of the file in which to write the
merged result. This will usually be the name if a
change source file in the development directory.
It is important that this command does not move files around.
(See the obsolete diff3_command field, below, for some
history.)
Executed as: the project owner (for integration diffs), or the
developer (for development diffs). Current directory: the
integration directory (for integration diffs), or the
development directory (for development diffs). Exit status:
zero indicates success, all non-zero exits indicate failure
(the aed will fail).
patch_diff_command = string;
The difference of 2 files, to send around as a patch. (This
isn’t the same as diff_command, because it’s aimed at GNU
Patch, not at humans.) The command is always executed by
developers. Used by the aepatch(1) command.
Defaults to "set +e; diff -c -L $index -L $index $original
$input > $output; test $? -le 1" if not set.
All of the substitutions described by aesub(5) are available;
in addition,
${ORiginal}
The absolute path of the original file copied into the
change. Usually in the baseline, but not always.
${Input}
The absolute path of the file in the development
directory.
${Output}
The absolute path of the file in which to write the
difference listing.
${INDex}
The project-relative name of the file, for use when the
file name is embedded in the output. (Optional.)
Executed as: the project owner (for integration diffs), or the
developer (for development diffs). Current directory: the
integration directory (for integration diffs), or the
development directory (for development diffs). Exit status:
zero indicates success, all non-zero exits indicate failure
(the aed will fail).
annotate_diff_command = string;
The difference of 2 files, for the use of the aeannotate(1)
command. (This isn’t the same as the diff_command field,
because it’s aimed at aeannotate(1), not at humans.) The
command is always executed by developers. Used by the
aeannotate(1) command.
Extreme care should be taken if you are considering setting
this field, otherwise the result reported by aeannotate(1) may
bear little relation to reality. The most useful option is GNU
diff’s --ignore-all-space option, which will have the effect of
ignoring the majority of indenting and code formatting changes.
The --ignore-case option could also be useful for case
insensitive languages such as FORTRAN or PL/1. Avoid options
which would alter the number of lines, such as - -ignore-blank-
lines or --context as these will produce misleading results.
Defaults to "set +e; diff $option $original $input > $output;
test $? -le 1" if not set.
All of the substitutions described by aesub(5) are available;
in addition,
${ORiginal}
The absolute path of the original file copied into the
change. Usually in the baseline, but not always.
${Input}
The absolute path of the file in the development
directory.
${Output}
The absolute path of the file in which to write the
difference listing.
${INDex}
The project-relative name of the file, for use when the
file name is embedded in the output. (Optional.)
${OPTion}
Extra options to be passed to the diff command, as set
by the aeannotate(1) -diff-option command line option.
Use with extreme care.
Executed as: the project owner (for integration diffs), or the
developer (for development diffs). Current directory: the
integration directory (for integration diffs), or the
development directory (for development diffs). Exit status:
zero indicates success, all non-zero exits indicate failure
(the aed will fail).
review_policy_command = string;
This field is used to set the command to be executed by the
aerpass(1) command. This command is useful in cases where the
enterprise has determined that more than one review is
necessary or that the reviewer must be senior to the developer,
etc. Defaults to "exit 0" if not set.
The exit status is examined. An zero exit status (success)
means that the change will proceed to the awaiting integration
state; a non-zero exit status (failure) means that the change
requires further review state, and the develop_end_action is
consulted to determine the appropriate state (awaiting_review
or being_reviewed) for the change to move to.
All of the substitutions described by aesub(5) are available.
Of particular interest are ${Change_Developer_List} and
${Change_Reviewer_List} for passing the specific staff involved
with the change.
Executed as: the current reviewer. Current directory: the
development directory. Exit status: zero indicates success,
non-zero indicates failure.
For example, to have a script which is a project source file to
be used to gate the code review process, a setting such as the
following may be used:
review_policy_command =
"$sh ${source script/reviewpolicy.sh} "
"-p $project -c $change "
"-d ${developer_list} "
"-r ${reviewer_list}"
;
This is only one of many ways to implement a project specific
review policy.
develop_end_policy_command = string;
This field is used to set the command to be executed by the
aede(1) command. This command is useful in cases where the
enterprise has determined that additional pre-conditions must
be met (in addition to those already imposed by the aede(1)
command) before a change may leave the being developed state.
Defaults to "exit 0" if not set.
The exit status is examined. An zero exit status (success)
means that the change may leave to the being developed state; a
non-zero exit status (failure) means that the change requires
further development.
All of the substitutions described by aesub(5) are available.
Executed as: the developer. Current directory: the development
directory. Exit status: zero indicates success, non-zero
indicates failure.
There are some common validations available in the aede-
policy(1) command; you may choose all or only some of them, or
you may choose to write a policy command specific to your
project.
unchanged_file_develop_end_policy = (...);
This field may be used to control what happens when development
of a change is ended, and the change contains files which have
not had their contents or their attributes changed.
ignore Does not look for or warn about unchanged files. This
the default.
warning If the change sets contains unchanged files, a warning
will be issued for each one.
error If the change set contains unchanged files, an error
will be issued for each one, and develop end will not
complete (the change will remain in the being developed
state).
unchanged_file_integrate_pass_policy = (...);
This field may be used to control what happens when a change is
completed, and the change contains files which have not had
their contents or their attributes changed.
ignore Does not look for or warn about unchanged files. The
file version will be added to the history. This the
default.
warning If the change sets contains unchanged files, a warning
will be issued for each one. The file version will be
added to the history.
remove If the change set contains an unchanged file, it will
be silently removed from the change set. The file
version will not be added to the history. The project
file is unaffected.
test_command = string;
This field is used to set the command to be executed by the
aet(1) command. Defaults to "$shell $file_name" if not set.
All of the substitutions described in aesub(5) are available.
In addition:
${File_Name}
The absolute path of the test to be executed.
${Search_Path}
Colon separated list of directories to search for tests
and test support files. (This is a normal aesub(5)
substitution.)
${Search_Path_Executable}
Colon separated list of directories to search for
executable files and executable support files. Usually
it is the same as the above, except during an “aet -bl”
command.
${VARiables}
The text of name=value variable settings from the
command line, suitably quoted to protect special
character from the shell. Will be appended to the end
of the command if not used explicitly.
Note that tests are source files, and thus never have the
execute bit set.
Executed as: the project owner (for integration tests) or the
developer (for development tests), or the executing user (for
-independent tests). Current directory: the integration
directory (for integration tests), the development directory
(for development tests), the project baseline (for -bl tests),
or the current directory (for -independent tests). Exit
status: zero indicates success, one indicates failure, anything
else indicates "no result".
development_test_command = string;
This field is used to set the command to be executed by the
aet(1) command when a change is in the being developed state.
Defaults to be the same as the test_command field if not set.
Note: It is a significantly bad idea to make tests behave
differently in being development and being integrated states;
avoid this at all costs.
All of the substitutions described in aesub(5) are available.
In addition:
${File_Name}
The absolute path of the test to be executed.
${File_Name}
The absolute path of the test to be executed.
${Search_Path}
Colon separated list of directories to search for tests
and test support files. (This is a normal aesub(5)
substitution.)
${Search_Path_Executable}
Colon separated list of directories to search for
executable files and executable support files. Usually
it is the same as the above, except during an “aet -bl”
command.
${VARiables}
The text of name=value variable settings from the
command line, suitably quoted to protect special
character from the shell. Will be appended to the end
of the command if not used explicitly.
Note that tests are source files, and thus never have the
execute bit set.
Executed as: the developer. Current directory: the development
directory (for development tests), the project baseline (for
-bl tests). Exit status: zero indicates success, one indicates
failure, anything else indicates "no result".
batch_test_command = string;
This field is used to set the command to be executed by the
aet(1) command, in preference to the test_command or
development_test_command, if set. It is capable of running
more than one test at once.
All of the substitutions described in aesub(5) are available.
In addition:
${Output}
This is the name of the file to be generated to hold the
test results. See aetest(5) for the format of this
file.
A space separated list of absolute paths of the tests to
be executed.
${File_Names}
The absolute path of the tests to be executed.
${File_Name}
The absolute path of the test to be executed.
${Search_Path}
Colon separated list of directories to search for tests
and test support files. (This is a normal aesub(5)
substitution.)
${Search_Path_Executable}
Colon separated list of directories to search for
executable files and executable support files. Usually
it is the same as the above, except during an “aet -bl”
command.
${Current}
Number of first test in the batch.
${Total}
Total number of tests. If this is 0 then no progress
messages should be issued.
${VARiables}
The text of name=value variable settings from the
command line, suitably quoted to protect special
character from the shell. Will be appended to the end
of the command if not used explicitly.
Note that tests are source files, and thus never have the
execute bit set.
It is strongly recommended that you design your test scripts so
that they may be executed by either batch or non-batch methods.
This permits simple migration when your environment changes.
Executed as: the project owner (for integration tests) or the
developer (for development tests), or the executing user (for
-independent tests). Current directory: the integration
directory (for integration tests), the development directory
(for development tests), the project baseline (for -bl tests),
or the current directory (for -independent tests). Exit
status: zero indicates success, one indicates failure, anything
else indicates "no result".
architecture_discriminator_command = string;
If this field is present it is used as a command to be executed
in order to further identify the platform architecture (see
below). All of the substitutions described by aesub(5) are
available;
Executed as: the developer. Current directory: the development
directory of the change. Exit status: zero indicates success,
all non-zero exits indicate failure.
architecture = [{ ... }];
This field is a list of system and machine architectures on
which each change must successfully build and test. May be
assigned more than once. The structures listed have fields as
follows:
name = string;
The name of the architecture. This name is available
in the ${ARCHitecture} substitution (see aesub(5) for
more information), as well as being used internally by
Aegis. You may use almost any name for your
architecture, but it is best to avoid shell special
characters and white space, because it may be
substituted into commands to be executed by Aegis.
pattern = string;
The system and machine architecture are determined by
using the uname(2) system call. The uname(2) return
value is assembled into a string of the form "sysname-
release-version-machine", or "sysname-release-version-
machine-disc" if architecture_discriminator_command is
used.
The pattern field must match this uname result string.
The first match found is used. The pattern is a shell
file name pattern, see sh(1) for more information.
For example, the pattern SunOS-4.1*-*-sun4* matches a
machine the author commonly uses, which returns
SunOS-4.1.3-8-sun4m from the uname(2) system call.
mode = (required, optional, forbidden);
The mode field is used to control how the architecture
information is used.
required
Architectures of thus mode will be copied into
changes as their required architectures when
the change is created. This is the default.
optional
Architectures of thus mode will not be copied
into changes as their required architectures
when the change is created. However, if you
add them subsequently, they become required for
that change.
forbidden
Aegis will refuse to build or test on
architectures of this mode.
When a change is created, the required architecture
names are copied into the change’s architecture list.
Once names are in this list, they are required for the
change, and the project attributes are less relevant.
If the architecture field is not set, it defaults to
architecture =
[
{
name = "unspecified";
pattern = "*";
mode = required;
}
];
file_template = [ { ... } ];
The file template is consulted whenever a new file is created,
by one of the aenf(1) or aent(1) commands. May be assigned
more than once. Each list item has the form:
pattern = [ string ];
The name of the file, relative to the development
directory. Each string is a shell file name pattern;
see sh(1) for more information. The patterns are
matched against the whole filename; naming only the
last filename path element will not work (unless the
pattern starts with “*”).
body_command = string;
Command to run to initialize the body of the file.
Executed as: the developer. Current directory: the
development directory of the change. Exit status:
ignored.
body = string;
What to initialize the body of the file to.
All of the substitutions described in aesub(5) are available
for the body and body_command strings. (Only specify one of
them.) In addition:
${File_Name}
will be replaced by the name of the new file.
whiteout_template = [ { ... } ];
The file template is consulted whenever a file is removed, by
one of the aerm(1) or aemv(1) commands. It is used to place a
“whiteout” entry in the development directory, in order to
induce compile errors of the removed file is referenced during
the build. Each list item has the form:
pattern = [ string ];
The name of the file, relative to the development
directory. Each string is a shell file name pattern;
see sh(1) for more information. The patterns are
matched against the whole filename; naming only the
last filename path element will not work (unless the
pattern starts with “*”).
body = string;
What to initialize the body of the file to. If not
present, no whiteout file will be created; if the empty
string, a zero-length whiteout file will be created.
All of the substitutions described in aesub(5) are available
for the body string. In addition:
${File_Name}
will be replaced by the name of the removed file.
If the name of the file being removed does not match any of the
filename patterns, a file consisting of 1KB of very ugly
garbage will be generated. The idea is that it will produce a
syntax error for most languages if you try to run it, compile
it, or include it.
maximum_filename_length = integer;
This field is used to limit the length of file names. All new
files may not have path components longer than this. Existing
files are not affected. The last component must also allow for
the ",D" suffix of difference files. Where this value is
larger than the file system allows, the file system limit will
be imposed. Defaults to 255 if not set. Legal values range
from 9 to 255.
The file name lengths of project files will be checked at
develop end if the project aegis.conf file is in the change.
See aede (1) for more information.
posix_filename_charset = boolean;
This field may be used to limit the characters allowed in file
names to only those explicitly allowed by POSIX. Defaults to
false if not set.
For a filename to be portable across conforming implementations
of IEEE Std 1003.1-1988, it shall consist only of alphanumeric
characters, dot, hyphen or underscore. Hyphen shall not be
used as the first character of a portable filename.
If this field is false, all characters are allowed except non-
printing characters, space characters and leading hyphens.
dos_filename_required = boolean;
This field may be used to limit file names so that they conform
to the DOS 8+3 filename limits and to the DOS filename
character set. Also denies file names which look like devices
(AUX, etc). Defaults to false if not set. This field is used
in combination with the other filename fields, it does not
replace them.
windows_filename_required = boolean;
This field may be used to limit file names so that they conform
to the Windows98 and WindowsNT filename limits and character
set. Also denies file names which look like devices (AUX,
etc). Defaults to false if not set. This field is used in
combination with the other filename fields, it does not replace
them.
shell_safe_filenames = boolean;
This field may be used to limit file names so that they may not
contain shell special characters. If you do not set this to
true, you will need to use the ${quote} substitution around
file names in commands, or risk unexpected errors.
This field defaults to true if not set.
The white space characters (space, tab, newline, etc) are
considered shell special characters.
allow_white_space_in_filenames = boolean;
This field may be used to allow white space characters in file
names. This will allow the following characters to appear in
filenames: backspace (BS, \b, 0x08), horizontal tab (HT, \t,
0x09), new line (NL, \n, 0x0A), vertical tab (VT, \v, 0x0B),
form feed (FF, \f, 0x0C), and carriage return (CR, \r, 0x0D).
Defaults to false if not set.
Note that this field does not override other file name filters.
It will be necessary to explicitly set shell_safe_filenames =
false as well. It will be necessary to set dos_filename_
required = false (the default) as well. It will be necessary
to set posix_filename_charset = false (the default) as well.
The user must take great care to use the ${quote} substitution
around all file names in commands in the project configuration.
And even then, substitutions which expect a space separated
list of file names will have undefined results.
allow_non_ascii_filenames = boolean;
This field may be used to allow file names with non-ascii-
printable characters in them. Usually this would mean a UTF8
or international charset of some kind.
Defaults to false if not set.
Note that this field does not override other file name filters.
It will be necessary to explicitly set shell_safe_filenames =
false as well. It will be necessary to set dos_filename_
required = false (the default) as well. It will be necessary
to set posix_filename_charset = false (the default) as well.
filename_pattern_accept = [ string ];
This field is used to specify a list of patterns of acceptable
file names. The patterns are matched against each filename
path element. The patterns are constructed from the usual
shell filename wild-cards. Defaults to "*" if not set.
filename_pattern_reject = [ string ];
This field is used to specify a list of patterns of
unacceptable file names. The patterns are matched against each
filename path element. The patterns are constructed from the
usual shell filename wild-cards. Defaults to "*,D" if not set.
The pattern "*,D" is always appended. Where the
filename_pattern_accept and filename_pattern_reject fields
conflict, the reject takes precedence.
new_test_filename = string;
This field is used to form the filename of new tests, where the
filename is not specified on the aent command line. Defaults
to "test/${zpad $hundred 2}/t${zpad $number 4}${left $type
1}.sh" if not set.
All of the substitutions defined in aesub(5) are available.
The following three substitutions are also available:
$Hundred
The test number divided by 100, optional
$Number The test number, mandatory
$Type The test type: "automatic" or "manual", optional
development_directory_template = string;
This field is used to determine the name of the development
directory at develop begin. All of the substitutions defined
in aesub(5) are available. The following substitutions is also
available:
Default_Development_Directory
The directory within which the development directory is
to be created.
Magic A single letter, starting from “C”, which can be
inserted. This must be used, as it allows Aegis to try
different names should there be a conflict.
If not set, defaults to "$ddd/${left $p ${expr ${namemax $ddd}
- ${length .$magic$c}}}.$magic$c".
For DOS compatibility (8+3 file names), a useful setting is
"$ddd/${downcase ${left ${id $p} 8}.$magic${right 0$c 2}}".
This ensures that the filename is always a valid 8.3 filename,
that it is always lowercase, and it translates any punctuation
in the project name into underscores.
metrics_filename_pattern = string;
This field is used to form the name of the metrics file, given
a source file. All of the substitutions defined in aesub(5)
are available. The following substitutions is also available:
File_Name
The absolute path name of the source file.
Defaults to "$filename,S" if not set.
trojan_horse_suspect = [ string ];
This list of filename patterns is consulted by aedist --receive
when it is checking for files which could be used to host
Trojan horse attacks. This will be different for different
projects, so you will need to update this yourself. The
patterns are matched against the whole filename; naming only
the last filename path element will not work (unless the
pattern starts with “*”).
project_specific = [ { ... } ];
This is a list of name and value pairs for use within the
${project-specific} substitution (see aesub(5) for more
information). May be assigned more than once. The sub-fields
are
name = string;
The name of the value. By convention, names which
start with an upper-case letter will appear in
listings, and lower-case will not. Attribute names are
case-insensitive.
value = string;
The value to be substituted.
There are almost no limitations on the strings which may appear
in either of these fields.
There are several attribute names which are known to and used
by Aegis, these include:
aede-policy
This attribute is used when no policy names are listed
on the aede-policy(1) command line.
aetar:exclude
This attribute is used by he aetar(1) receive command
to exclude files in tarballs from consideration. This
is a space separated list of file names.
html:meta
This attribute is used by the aeget(1) command to
customize generated web pages. See aeget(1) for more
information.
html:body-begin
This attribute is used by the aeget(1) command to
customize generated web pages. See aeget(1) for more
information.
html:body-end
This attribute is used by the aeget(1) command to
customize generated web pages. See aeget(1) for more
information.
copyright-owner
This string is available via the ${copyright-owner}
substitution, and is the one checked by the aede-
policy(1) command. Only set this attribute if your
project is a work-for-hire under copyright law. It
defaults to the value of ${user name} if not set, this
is almost always correct for Open Source projects.
When commands are executed by Aegis, it ensures that the
AEGIS_PROJECT, AEGIS_CHANGE, AEGIS_ARCH, LINES and COLS
environment variables are set appropriately. The project
configuration file’s project_specific field is also consulted,
looking for value’s whose name starts with "setenv:" and sets
the corresponding environment variable. All of the
substitutions described by aesub(5) are available. For
example: specifying a PATH and a SEARCH_PATH to be used for all
commands may be set as follows:
project_specific =
[
{
name = "setenv:PATH";
value = "/usr/bin:/bin";
},
{
name = "setenv:SEARCH_PATH";
value = "${search_path}";
},
];
As many environment variables as desired may be specified in
this way.
build_time_adjust = (...);
This field controls the adjustment of file modification times
at the end of integrate-pass. File times are adjusted so that
development directories are, in the main, out of date with
respect to the baseline. The idea is that, at the very least,
programs need to be re-linked so that aet -reg does not give
false negatives.
Combining this with the project_file_command (above) can
alleviate the vast majority of file modification time
inconsistencies experienced as a result of a project
integration and the subsequent changes in the baseline’s file
modification times.
Unless you are a masochist, do not set this field. Leave it as
the default.
adjust_and_sleep
Causes the file times to be adjusted, and if the file
times would extend into the future, aeipass will sleep
until that time has passed. This is the default.
adjust_only
Causes the file times to be adjusted. If the file time
extend into the future, a warning is issued.
dont_adjust
File modification times are not adjusted. This is a
really bad idea. Really. Make sure that, at the very
minimum, project_file_command touches all of the
change’s files, otherwise the build problems which
ensue are going to take you weeks to track down and
lose you much productivity. You have been warned.
See also the build_time_adjust_notify_command field.
signed_off_by = boolean;
If this field is set each aedb(1), aechown(1), aede(1) and
aerpass(1) will append a Signed-off-by line to the change
description. This field should only be set to true for open
source projects.
For a description of Signed-off-by see
http://www.ussg.iu.edu/hypermail/linux/kernel/0405.2/.html
and
http://www.osdl.org/newsroom/press_releases/2004/2004_05_24_dco.html
cache_project_file_list_for_each_delta = boolean;
It is possible to have Aegis cache the list of project files
that were present at integrate pass for each delta (integrated
change set). This is used to optimize all project-history-
based operations, such as aecp -delta or aepatch(1).
This cache will optimize many operations which would otherwise
require time to reconstruct the project state using the roll-
forward data available in each change set. However, it comes
at the cost of disk space, and not everyone can afford more and
more disk.
This field defaults to true if not set.
clean_exceptions = [ string ];
It is possible to have Aegis exclude from the clean process any
file that match one of the pattern listed in the
clean_exceptions list.
This field default to an empty list if not set.
cache_project_file_list_for_each_delta = boolean;
It is possible to have Aegis cache the list of project files
that were present at integrate pass for each delta (integrated
change set). This is used to optimize all project-history-
based operations, such as aecp -delta or aepatch(1).
This cache will optimize many operations which would otherwise
require time to reconstruct the project state using the roll-
forward data available in each change set. However, it comes

This field defaults to true if not set.
RSS FEEDS
Aegis has the ability to feed RSS channels when change sets transition
states. See the User Guide for full details. Following is a brief
description of the project-specific attributes used to control this
process.
Create / Add to a channel
An RSS channel is specified with the rss:feedfilename
project_specific attribute:
project_specific =
[
{
name = "rss:feedfilename-<filename>";
value = "<space-separated list of states>";
}
]
Specify the Description of an RSS channel
The description of an RSS channel is specified with the
rss:feeddescription project_specific attribute:
project_specific =
[
{
name = "rss:feeddescription-<filename>";
value = "<description>";
}
]
Specify the Title of an RSS channel
The title of an RSS channel is specified with the rss:feedtitle
project_specific attribute:
project_specific =
[
{
name = "rss:feedtitle-<filename>";
value = "<title>";
}
]
Specify the Language of an RSS channel
The language of an RSS channel is specified with the
rss:feedlanguage project_specific attribute:
project_specific =
[
{
name = "rss:feedlanguage-<filename>";
value = "<language";
}
]
OBSOLETE FIELDS
There are some obsolete fields in the file. They are provided for
backwards compatibility only, and should not be used.
diff3_command = string;
This field is used to difference 3 files. The command is
always executed by developers. Used by the aed(1) command.
All of the substitutions described by aesub(5) are available;
in addition,
${ORiginal}
The absolute path of the original file copied into the
change. Usually not in the baseline.
${Most_Recent}
The absolute path of the competing edit, usually in the
baseline.
${Input}
The absolute path of the file in the development
directory.
${Output}
The absolute path of the file in which to write the
difference listing.
Executed as: the project owner (for integration diffs), or the
developer (for development diffs). Current directory: the
integration directory (for integration diffs), or the
development directory (for development diffs). Exit status:
zero indicates success, all non-zero exits indicate failure
(the aed will fail).
The problem with this field was that the default usage placed
the merged source in a strange place. And subsequent aed(1)
commands would over-write it. This meant that merges would be
lost, causing a number of nasty problems. Some sites overcame
this by adding “mv” commands to put the output back where the
input came from, but this meant that Aegis’ commentary was
misleading. Use the “merge_command” field instead. It is
almost identical, but Aegis will move the files around for you
- so you get the good behavior by default (no lost merges) and
the error message is consistent.
create_symlinks_before_build = boolean;
This flag is true if Aegis should create symlinks from the
development directory to the baseline for all files in the
baseline not in the development directory immediately before a
development_build_command is issued. Usually used to trick
dumb DMTs into believing the development directory contains an
entire copy of the project, though sometimes the DMT is smart
enough, the tools it must work with are not. Symlinks in the
development directory which point to nonexistent files will be
removed.
Defaults to false if not set.
create_symlinks_before_integration_build = boolean;
This flag is true if Aegis should create symlinks from the
integration directory to the ancestral baseline for all files
in the ancestral not in the integration directory immediately
before a build_command is issued. Usually used to trick dumb
DMTs into believing the integration directory contains an
entire copy of the project, though sometimes the DMT is smart
enough, the tools it must work with are not. Symlinks in the
integration directory which point to nonexistent files will be
removed.
Defaults to the same value as create_symlinks_before_build if
not set.
remove_symlinks_after_build = boolean;
This flag is true if Aegis should remove symlinks which point
from the development directory to the baseline directory
immediately after a development_build_command is issued. Only
consulted if the create_symlinks_before_build field is true,
for the purpose of reversing the actions of the create_
symlinks_before_build field.
Defaults to false if not set.
remove_symlinks_after_integration_build = boolean;
This flag is true if Aegis should remove symlinks which point
from the integration directory to the ancestral baseline
directory immediately after a build_command is issued. Only
consulted if the create_symlinks_before_integration_build field
is true, for the purpose of reversing the actions of the
create_symlinks_before_integration_build field.
Defaults to true if not set. This default is intentional. It
is important that there are no symlinks in the (new) baseline,
because they could go stale between integrations. If you set
this field to false, caveat emptor.
