.SH NAME
.I nightly
\- build an OS-Net consolidation overnight
.SH SYNOPSIS
\fBnightly [-in] [-V VERS] <env_file>\fP
.SH DESCRIPTION
.LP
.I nightly,
the mother of all build scripts,
can build, archive, package, error check, and
generally do everything it takes to
turn OS/Net consolidation source code into useful stuff.
It is customizable to permit you to run anything from a
simple build to all of the cross-checking a gatekeeper
needs.  The advantage to using
.I nightly
is that you build things correctly, consistently and
automatically, with the best practices; building with
.I nightly
can mean never having to say you're sorry to your
gatekeeper.
.LP
More
specifically,
.I nightly
performs the following tasks, in order, if
all these things are desired:
.LP
.RS
.TP
\(bu
perform a "make clobber" to clean up old binaries
.TP
\(bu
perform non-DEBUG and DEBUG builds
.TP
\(bu
list proto area files and compare with previous list
.TP
\(bu
copy updated proto area to parent
.TP
\(bu
list shared lib interface and compare with previous list
.TP
\(bu
perform a "make check" to report hdrchk/cstyle errors
.TP
\(bu
report the presence of any core files
.TP
\(bu
check the ELF runtime attributes of all dynamic objects
.TP
\(bu
check for unreferenced files
.TP
\(bu
report on which proto area objects have changed (since the last build)
.TP
\(bu
report the total build time
.TP
\(bu
save a detailed log file for reference
.TP
\(bu
mail the user a summary of the completed build
.RE
.LP
The actions of the script are almost completely determined by
the environment variables in the
.I env
file, the only necessary argument.  Ths only thing you really
need to use
.I nightly
is an
.I env
file that does what you want.
.LP
Like most of the other build tools in usr/src/tools, this script tends
to change on a fairly regular basis; do not expect to be able to build
OS/Net with a version of nightly significantly older than your source
tree.  It has what is effectively a Consolidation Private relationship
to other build tools and with many parts of the OS/Net makefiles,
although it may also be used to build other consolidations.
.SH NIGHTLY_OPTIONS
The environment variable NIGHTLY_OPTIONS controls the actions
.I nightly
will take as it proceeds.
The -i, -n, and -V options may also be used from the command
line to control the actions without editing your environment file.
The -i and -n options complete the build more quickly by bypassing
some actions. If NIGHTLY_OPTIONS is not set, then "-Bmt" build
options will be used.

.B Basic action options
.TP 10
.B \-D
Do a DEBUG build instead of non-DEBUG
.TP
.B \-M
Do not run pmodes (safe file permission checker)
.TP
.B \-i
Do an incremental build, suppressing the "make clobber" that by
default removes all existing binaries and derived files.  From the
command line, -i also suppresses the cstyle/hdrchk pass
.TP
.B \-p
Create packages for regular install
.TP
.B \-m
Send mail to $MAILTO at end of build
.TP

.LP
.B Code checking options
.TP 10
.B \-A
Check for ABI discrepancies in .so files.
It is only required for shared object developers when there is an
addition, deletion or change of interface in the .so files.
.TP
.B \-C
Check for cstyle/hdrchk errors
.TP
.B \-f
Check for unreferenced files.  Since the full workspace must be built
in order to accurately identify unreferenced files, -f is ignored for
incremental (-i) builds, or builds that do not include -p.
.TP
.B \-r
Check the ELF runtime attributes of all dynamic objects
.TP
.B \-N
Do not run protocmp or checkpaths (note: this option is not
recommended, especially in conjunction with the \-p option)
.TP
.B \-w
Report which proto area objects differ between this and the last build.
See wsdiff(1ONBLD) for details. Note that the proto areas used for comparison
are the last ones constructed as part of the build. As an example, if both
a non-debug and debug build are performed (in that order), then the debug
proto area will be used for comparison (which might not be what you want).
.LP
.B Groups of options
.TP 10
.B \-G
Gate keeper default group of options
.TP
.B \-I
Integration engineer default group of options (-mp)
.TP
.B \-R
Default group of options for building a release (-mp)

.LP
.B Miscellaneous options
.TP 10
.B \-V VERS
set the build version string to VERS, overriding VERSION

.SH ENVIRONMENT VARIABLES
.LP
Here is a list of prominent environment variables that
.I nightly
references and the meaning of each variable.
.B SRCTOP
.RS 5
The root of your workspace, including whatever metadata is kept by
the source code management system.  This is the workspace in which the
build will be done.
.RE
.LP
.B SRC
.RS 5
Root of OS-Net source code, referenced by the Makefiles.  It is
the starting point of build activity.  It should be expressed
in terms of $SRCTOP.
.RE
.LP
.B ROOT
.RS 5
Root of the proto area for the build.  The makefiles direct
installation of build products to this area and
direct references to these files by builds of commands and other
targets.  It should be expressed in terms of $SRCTOP.
.RE
.LP
.B MACH
.RS 5
The instruction set architecture of the build machine as given
by \fIuname -p\fP, e.g. sparc, i386.
.RE
.LP
.B ATLOG
.RS 5
The location of the log directory maintained by
.IR nightly .
This should generally be left to the default setting.
.RE
.LP
.B LOGFILE
.RS 5
The name of the log file in the $ATLOG directory maintained by
.IR nightly .
This should generally be left to the default setting.
.RE
.LP
.B MAILTO
.RS 5
The address to be used to send completion e-mail at the end of
the build (for the \-m option).
.RE
.LP
.B RELEASE
.RS 5
The release version number to be used; e.g., 5.10.1 (Note: this is set
in Makefile.master and should not normally be overridden).
.RE
.LP
.B VERSION
.RS 5
The version text string to be used; e.g., "onnv:`date '+%Y-%m-%d'`".
.RE
.LP
.B RELEASE_DATE
.RS 5
The release date text to be used; e.g., October 2009. If not set in
your environment file, then this text defaults to the output from
$(LC_ALL=C date +"%B %Y"); e.g., "October 2009".
.RE
.LP
.B RELEASE_BUILD
.RS 5
Define this to build a release with a non-DEBUG kernel.
Generally, let
.I nightly
set this for you based on its options.
.RE
.LP
.B PKGARCHIVE
.RS 5
The destination for packages.  This may be relative to $SRCTOP for
private packages.
.RE
.LP
.B MAKEFLAGS
.RS 5
Set default flags to make; e.g., -k to build all targets regardless of errors.
.RE
.LP
.B BUILD_TOOLS
.RS 5
BUILD_TOOLS is the root of all tools including the compilers; e.g.,
/ws/onnv-tools.  It is used by the makefile system, but not nightly.
.RE
.LP
.B ONBLD_TOOLS
.RS 5
ONBLD_TOOLS is the root of all the tools that are part of SUNWonbld; e.g.,
/ws/onnv-tools/onbld.  By default, it is derived from
.BR BUILD_TOOLS .
It is used by the makefile system, but not nightly.
.RE
.LP
.B JAVA_ROOT
.RS 5
The location for the java compilers for the build, generally /usr/java.
.RE
.LP
.B OPTHOME
.RS 5
The gate-defined default location of things formerly in /opt; e.g.,
/ws/onnv-tools.  This is used by nightly, but not the makefiles.
.RE
.LP
.B CHECK_PATHS
.RS 5
Normally, nightly runs the 'checkpaths' script to check for
discrepancies among the files that list paths to other files, such as
the exception lists.  Set this flag to 'n' to disable this
check, which appears in the nightly output as "Check lists of files."
.RE
.SH NIGHTLY HOOK ENVIRONMENT VARIABLES
.LP
Several optional environment variables may specify commands to run at
various points during the build.  Commands specified in the hook
variable will be run in a subshell; command output will be appended to
the mail message and log file.  If the hook exits with a non-zero
status, the build is aborted immediately.  Environment variables
defined in the environment file will be available.
.LP
.B SYS_PRE_NIGHTLY
.RS 5
This is reserved for per-build-machine customizations.
.RE
.LP
.B PRE_NIGHTLY
.RS 5
Run just after SYS_PRE_NIGHTLY.
.RE
.LP
.B POST_NIGHTLY
.RS 5
Run after the build completes, with the return status of nightly - one
of "Completed", "Interrupted", or "Failed" - available in the
environment variable NIGHTLY_STATUS.
.RE
.LP
.B SYS_POST_NIGHTLY
.RS 5
This is reserved for per-build-machine customizations, and runs
immedately after POST_NIGHTLY.
.RE
.SH EXAMPLES
.LP
Start with the example file in usr/src/tools/env/developer.sh
(or gatekeeper.sh), copy to myenv and make your changes.
