.I nightly
\- build an OS-Net consolidation overnight
.SH SYNOPSIS
\fBnightly [-in] [-V VERS] <env_file>\fP
.LP
.SH DESCRIPTION
.IX "OS-Net build tools" "nightly" "" "\fBnightly\fP"
.LP
.I nightly,
the mother of all build scripts,
can bringover, 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
bringover from the identified parent gate/clone
.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 lint" of the kernel and report errors
.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

.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.
.LP
.SH NIGHTLY_OPTIONS
The environment variable NIGHTLY_OPTIONS controls the actions
.I nightly
will take as it proceeds.
The -i, -n, +t 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 build with DEBUG on (non-DEBUG is built by default)
.TP
.B \-F
Do _not_ do a non-DEBUG build (use with -D to get just a DEBUG build)
.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 lint pass and the cstyle/hdrchk
pass
.TP
.B \-n
Suppress the bringover so that the build will start immediately with
current source code
.TP
.B \-p
Create packages for regular install
.TP
.B \-U
Update proto area in the parent workspace
.TP
.B \-u
Update the parent workspace with files generated by the build, as follows.
.RS
.TP
\(bu
Copy proto_list_${MACH} and friends to usr/src in the parent.
.TP
\(bu
When used with -f, build a usr/src/unrefmaster.out in
the parent by merging all the usr/src/unref-${MACH}.out files in the
parent.
.TP
\(bu
When used with -A or -r, copy the contents of the resulting
ELF-data.${MACH} directory to usr/src/ELF-data.${MACH} in the parent
workspace.
.RE
.TP
.B \-m
Send mail to $MAILTO at end of build
.TP
.B \-t
Build and use the tools in $SRC/tools (default setting).
.TP
.B \+t
Use the build tools in "$ONBLD_TOOLS/bin".

.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 -l, and -p.
.TP
.B \-r
Check the ELF runtime attributes of all dynamic objects
.TP
.B \-l
Do "make lint" in $LINTDIRS (default: $SRC n)
.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(1) 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 (-u)
.TP
.B \-I
Integration engineer default group of options (-mpu)
.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

.LP
.SH ENVIRONMENT VARIABLES
.LP
Here is a list of prominent environment variables that 
.I nightly
references and the meaning of each variable.
.LP
.RE
.B CODEMGR_WS
.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 PARENT_WS
.RS 5
The root of the workspace that is the parent of the
one being built.  This is particularly relevant for configurations
with a main
workspace and build workspaces underneath it; see the 
\-u and \-U
options as well as the PKGARCHIVE environment variable, for more
information.
.RE
.LP
.B BRINGOVER_WS
.RS 5
This is the workspace from which
.I nightly
will fetch sources to either populate or update your workspace;
it defaults to $CLONE_WS.
.RE
.LP
.B CLONE_WS
.RS 5
This is the workspace from which
.I nightly
will fetch sources by default.  This is
often distinct from the parent, particularly if the parent is a gate.
.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 $CODEMGR_WS.
.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 $CODEMGR_WS.
.LP
If $MULTI_PROTO is "no", $ROOT may contain a DEBUG or non-DEBUG
build.  If $MULTI_PROTO is "yes", $ROOT contains the DEBUG build and
$ROOT-nd contains the non-DEBUG build.
.RE
.LP
.B TOOLS_ROOT
.RS 5
Root of the tools proto area for the build.  The makefiles direct
installation of tools build products to this area.  Unless \fB+t\fR
is part of $NIGHTLY_OPTIONS, these tools will be used during the
build.
.LP
As built by nightly, this will always contain non-DEBUG objects.
Therefore, this will always have a -nd suffix, regardless of
$MULTI_PROTO.
.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 LOCKNAME
.RS 5
The name of the file used to lock out multiple runs of
.IR nightly .
This should generally be left to the default setting.
.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 STAFFER
.RS 5
The non-root account to use on the build machine for the
bringover from the clone or parent workspace.
This may not be the same identify used by the SCM.
.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 MAILFROM
.RS 5
The address to be used for From: in the completion e-mail at the
end of the build (for the \-m option).
.RE
.LP
.B REF_PROTO_LIST
.RS 5
Name of file used with protocmp to compare proto area contents.
.RE
.LP
.B PARENT_ROOT
.RS 5
The parent root, which is the destination for copying the proto
area(s) when using the \-U option.
.RE
.LP
.B PARENT_TOOLS_ROOT
.RS 5
The parent tools root, which is the destination for copying the tools
proto area when using the \-U 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
$CODEMGR_WS for private packages or relative to $PARENT_WS
if you have different workspaces for different architectures
but want one hierarchy of 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 UT_NO_USAGE_TRACKING
.RS 5
Disables usage reporting by listed Devpro tools. Otherwise it sends mail
to some Devpro machine every time the tools are used.
.RE
.LP
.B LINTDIRS
.RS 5
Directories to lint with the \-l option.
.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 SPRO_ROOT
.RS 5
The gate-defined default location for the Sun compilers, e.g.
/ws/onnv-tools/SUNWspro.  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 TEAMWARE
.RS 5
The gate-defined default location for the Teamware tools; e.g.,
/ws/onnv-tools/SUNWspro.  By default, it is derived from
.BR OPTHOME .
This is used by nightly, but not the makefiles.  There is no
corresponding variable for Mercurial or Subversion, which are assumed
to be installed in the default path.
.RE
.LP
.B ON_CLOSED_BINS
.RS 5
OpenSolaris builds do not contain the closed source tree.  Instead,
the developer downloads a closed binaries tree and unpacks it.  
.B ON_CLOSED_BINS
tells nightly
where to find these closed binaries, so that it can add them into the
build.
.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
exception lists and req.flg.  Set this flag to 'n' to disable this
check, which appears in the nightly output as "Check lists of files."
.RE
.LP
.B CHECK_DMAKE
.RS 5
Nightly validates that the version of dmake encountered is known to be
safe to use.  Set this flag to 'n' to disable this test, allowing any
version of dmake to be used.
.RE
.LP
.B MULTI_PROTO
.RS 5
If "no" (the default), 
.I nightly
will reuse $ROOT for both the DEBUG and non-DEBUG builds.  If "yes",
the DEBUG build will go in $ROOT and the non-DEBUG build will go in
$ROOT-nd.  Other values will be treated as "no".
.RE
.LP
.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
Run just after the workspace lock is acquired.  This is reserved for
per-build-machine customizations and should be set only in /etc/nightly.conf
.RE
.LP
.B PRE_NIGHTLY
.RS 5
Run just after SYS_PRE_NIGHTLY.
.RE
.LP
.B PRE_BRINGOVER
.RS 5
Run just before bringover is started; not run if no bringover is done.
.RE
.LP
.B POST_BRINGOVER
.RS 5
Run just after bringover completes; not run if no bringover is done.
.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.
