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
-o Do an "old style" (pre-S10) build using root privileges to set OWNER and GROUP from the Makefiles.
-a Create BFU archives
-z Compress cpio archives with gzip
-p Create packages for regular install
-U Update proto area in the parent workspace
-u Copy proto_list_${MACH} and friends to usr/src in the parent workspace. When used with -f, also build a usr/src/unrefmaster.out in the parent by merging all the usr/src/unref-${MACH}.out files in the parent.
-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 Do not report warnings (for freeware gate ONLY)
-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).
Groups of options
10 -G Gate keeper default group of options (-au)
-I Integration engineer default group of options (-ampu)
-R Default group of options for building a release (-mp)
Source Build options
10 -S E | D | H Build the Export, Domestic, or Hybrid source product. Only Export and Domestic are truly buildable at this time.
10 -S O Simulate an OpenSolaris build on a full tree. This can be used by internal developers to ensure that they haven't broken the build for external developers.
Source build options only make sense for a full internal tree (open and closed source). Only one source build option can be specified at a time.
Miscellaneous options
10 -O generate deliverables for OpenSolaris. Tarballs containing a source snapshot, binaries of closed-source components, compiled ON tools (SUNWonbld), and BFU archives are put in $CODEMGR_WS.
10 -V VERS set the build version string to VERS, overriding VERSION
-X Copies the proto area and packages from the IHV and IHV-bin gates into the nightly proto and package areas. This is only available on i386. See REALMODE ENVIRONMENT VARIABLES and BUILDING THE IHV WORKSPACE below.
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, and the CPIODIR and PKGARCHIVE environment variables, 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.
CLOSED_BRINGOVER_WS
A full Mercurial workspace has two repositories: one for open source and one for closed source. If this variable is non-null, nightly will pull from the repository that it names to get the closed source. It defaults to $CLOSED_CLONE_WS.
If $CODEMGR_WS already exists and contains only the open repository, nightly will ignore this variable; you'll need to pull the closed repository by hand if you want it.
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.
CLOSED_CLONE_WS
This is the default closed-source Mercurial repository that nightly might pull from (see CLOSED_BRINGOVER_WS for details).
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 the installation of header files and libraries 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.
For OpenSolaris deliveries (-O), $ROOT-open contains the DEBUG build of just the open source tree, and $ROOT-open-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).
REF_PROTO_LIST
Name of file used with protocmp to compare proto area contents.
CPIODIR
The destination for cpio archives. This may be relative to $CODEMGR_WS for private archives or relative to $PARENT_WS if you have different workspaces for different architectures but want one hierarchy of BFU archives.
PARENT_ROOT
The parent root, which is the destination for updated headers and libraries 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 2007.
INTERNAL_RELEASE_BUILD
See Makefile.master - but it mostly controls id strings. Generally, let nightly set this for you.
RELEASE_BUILD
Define this to build a release with a non-DEBUG kernel. Generally, let nightly set this for you based on its options.
PKGDEFS
PKGARCHIVE
The destination for packages. This may be relative to $CODEMGR_WS for private archives or relative to $PARENT_WS if you have different workspaces for different architectures but want one hierarchy of BFU archives.
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.
TEAMWARE
The gate-defined default location for the Teamware tools; e.g., /ws/onnv-tools/SUNWspro. By default, it is derived from 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.
EXPORT_SRC
The source product has no SCCS history, and is modified to remove source that cannot be shipped. EXPORT_SRC is where the clear files are copied, then modified with 'make EXPORT_SRC'.
CRYPT_SRC
CRYPT_SRC is similar to EXPORT_SRC, but after 'make CRYPT_SRC' the files in xmod/cry_files are saved. They are dropped on the exportable source to create the domestic build.
The open source tree is copied to this directory when simulating an OpenSolaris build (-S O). It defaults to $CODEMGR_WS/open_src.
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.
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."
CHECK_DMAKE
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.
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". Use of the -O flag forces MULTI_PROTO to "yes".
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.
The following environment variables referenced by nightly are only required when the -X option is used.
IA32_IHV_WS
Reference to the IHV workspace containing IHV driver binaries. The IHV workspace must be fully built before starting the ON realmode build.
Reference to the IHV workspace proto area. The IHV workspace must be fully built before starting the ON realmode build.
Reference to the IHV workspace packages. If this is empty or the directory is non-existent, then nightly will skip copying the packages.
Reference to binary-only IHV packages. If this is empty or the directory is non-existent, then nightly will skip copying the packages.
Destination for sparc realmode package SUNWrmodu. Yes, this sparc package really is built on x86.
If present, nightly executes this file just prior to executing the env file.
The IHV workspace can be built with nightly. The recommended options are:
NIGHTLY_OPTIONS="-pmWN"
None of the realmode environment variables needed for ON realmode builds are required to build the IHV workspace.
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
