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 nightly is that you build things correctly, consistently and automatically, with the best practices; building with nightly can mean never having to say you're sorry to your gatekeeper.
More specifically, nightly performs the following tasks, in order, if all these things are desired:
perform a "make clobber" to clean up old binaries
bringover from the identified parent gate/clone
perform non-DEBUG and DEBUG builds
list proto area files and compare with previous list
copy updated proto area to parent
list shared lib interface and compare with previous list
perform a "make lint" of the kernel and report errors
perform a "make check" to report hdrchk/cstyle errors
report the presence of any core files
check the ELF runtime attributes of all dynamic objects
check for unreferenced files
report on which proto area objects have changed (since the last build)
report the total build time
save a detailed log file for reference
mail the user a summary of the completed build
The actions of the script are almost completely determined by the environment variables in the env file, the only necessary argument. Ths only thing you really need to use nightly is an env file that does what you want.
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.
10 -D Do a build with DEBUG on (non-DEBUG is built by default)
-F Do _not_ do a non-DEBUG build (use with -D to get just a DEBUG build)
-M Do not run pmodes (safe file permission checker)
-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
-n Suppress the bringover so that the build will start immediately with current source code
-p Create packages for regular install
-U Update proto area in the parent workspace
-u Update the parent workspace with files generated by the build, as follows.
Copy proto_list_${MACH} and friends to usr/src in the parent.
When used with -f, build a usr/src/unrefmaster.out in the parent by merging all the usr/src/unref-${MACH}.out files in the parent.
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.
-m Send mail to $MAILTO at end of build
-t Build and use the tools in $SRC/tools (default setting).
\+t Use the build tools in "$ONBLD_TOOLS/bin".
Code checking options
10 -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.
-C Check for cstyle/hdrchk errors
-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.
-r Check the ELF runtime attributes of all dynamic objects
-l Do "make lint" in $LINTDIRS (default: $SRC n)
-N Do not run protocmp or checkpaths (note: this option is not recommended, especially in conjunction with the -p option)
-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).
Groups of options
10 -G Gate keeper default group of options (-u)
-I Integration engineer default group of options (-mpu)
-R Default group of options for building a release (-mp)
Miscellaneous options
10 -V VERS set the build version string to VERS, overriding VERSION
Here is a list of prominent environment variables that nightly references and the meaning of each variable. CODEMGR_WS
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.
PARENT_WS
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.
BRINGOVER_WS
This is the workspace from which nightly will fetch sources to either populate or update your workspace; it defaults to $CLONE_WS.
CLONE_WS
This is the workspace from which nightly will fetch sources by default. This is often distinct from the parent, particularly if the parent is a gate.
SRC
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.
ROOT
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.
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.
MACH
The instruction set architecture of the build machine as given by uname -p, e.g. sparc, i386.
LOCKNAME
The name of the file used to lock out multiple runs of nightly . This should generally be left to the default setting.
ATLOG
The location of the log directory maintained by nightly . This should generally be left to the default setting.
LOGFILE
The name of the log file in the $ATLOG directory maintained by nightly . This should generally be left to the default setting.
STAFFER
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.
MAILTO
The address to be used to send completion e-mail at the end of the build (for the -m option).
MAILFROM
The address to be used for From: in the completion e-mail at the end of the build (for the -m option).
REF_PROTO_LIST
Name of file used with protocmp to compare proto area contents.
PARENT_ROOT
The parent root, which is the destination for copying the proto area(s) when using the -U option.
PARENT_TOOLS_ROOT
The parent tools root, which is the destination for copying the tools proto area when using the -U option.
RELEASE
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).
VERSION
The version text string to be used; e.g., "onnv:`date '+%Y-%m-%d'`".
RELEASE_DATE
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".
RELEASE_BUILD
Define this to build a release with a non-DEBUG kernel. Generally, let nightly set this for you based on its options.
PKGARCHIVE
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.
MAKEFLAGS
Set default flags to make; e.g., -k to build all targets regardless of errors.
UT_NO_USAGE_TRACKING
Disables usage reporting by listed Devpro tools. Otherwise it sends mail to some Devpro machine every time the tools are used.
LINTDIRS
Directories to lint with the -l option.
BUILD_TOOLS
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.
ONBLD_TOOLS
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 BUILD_TOOLS . It is used by the makefile system, but not nightly.
SPRO_ROOT
The gate-defined default location for the Sun compilers, e.g. /ws/onnv-tools/SUNWspro. By default, it is derived from BUILD_TOOLS . It is used by the makefile system, but not nightly.
JAVA_ROOT
OPTHOME
The gate-defined default location of things formerly in /opt; e.g., /ws/onnv-tools. This is used by nightly, but not the makefiles.
ON_CLOSED_BINS
OpenSolaris builds do not contain the closed source tree. Instead, the developer downloads a closed binaries tree and unpacks it. ON_CLOSED_BINS tells nightly where to find these closed binaries, so that it can add them into the build.
CHECK_PATHS
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."
MULTI_PROTO
If "no" (the default), 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".
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.
SYS_PRE_NIGHTLY
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
PRE_NIGHTLY
Run just after SYS_PRE_NIGHTLY.
PRE_BRINGOVER
Run just before bringover is started; not run if no bringover is done.
POST_BRINGOVER
Run just after bringover completes; not run if no bringover is done.
POST_NIGHTLY
Run after the build completes, with the return status of nightly - one of "Completed", "Interrupted", or "Failed" - available in the environment variable NIGHTLY_STATUS.
SYS_POST_NIGHTLY
This is reserved for per-build-machine customizations, and runs immedately after POST_NIGHTLY.
If present, nightly executes this file just prior to executing the env file.
Start with the example file in usr/src/tools/env/developer.sh (or gatekeeper.sh), copy to myenv and make your changes.
0 # grep NIGHTLY_OPTIONS myenv
NIGHTLY_OPTIONS="-ACrlapDm"
export NIGHTLY_OPTIONS
# /opt/onbld/bin/nightly -i myenv
