They usually live in the /opt/onbld directory on build machines. From here, 'make install' will build and install the tools in $ROOT/opt/onbld. If you like, 'make pkg' will build the SUNWonbld package in $(PKGARCHIVE). Installing that package will populate the /opt/onbld directory, and create a root account for building called 'gk', which uses csh and has a home directory of /opt/onbld/gk. You can use this account to do full builds with 'nightly'. You don't have to, but the 'gk' account has the path setup properly, has a .make.machines file for dmake, and has a .login that sets up for dmake. Layout of /opt/onbld -------------------- /opt/onbld/etc/abi contains Solaris ABI database (ABI_*.db) and exceptions for ABI Auditing tool (intf_check). /opt/onbld/gk gk account's home directory. /opt/onbld/bin basic bin directory - contains scripts. /opt/onbld/bin/${MACH} architecture-specific bin directory for binaries. /opt/onbld/env build environment files. /opt/onbld/man rudimentary man pages for some of the tools. Tool Summary ------------ bfu bonwick/faulkner upgrade. Loads a set of cpio archives created by 'mkbfu' onto a machine, either live or on alternate root and /usr filesystems. Attempts to preserve important files, but may require manual intervention before reboot to resolve changes to preserved files. bfuld Used by bfu to survive getting a new runtime linker when extracting new cpio archives onto a live system. Patches binaries to use a saved runtime linker in /tmp during the bfu process. Not run by anything but bfu. bldenv companion to 'nightly.' Takes the same environment file you used with 'nightly,' and starts a shell with the environment set up the same way as 'nightly' set it up. This is useful if you're trying to quickly rebuild portions of a workspace built by 'nightly'. 'ws' should not be used for this since it sets the environment up differently and may cause everything to rebuild (because of different -I or -L paths). build_cscope builds cscope databases in the uts, the platform subdirectories of uts, and in usr/src. Uses cscope-fast. check_rtime checks ELF attributes used by ELF dynamic objects in the proto area. Used by 'nightly's -r option, to check a number of ELF runtime attributes for consistency with common build rules. nightly uses the -o option to simplify the output for diffing with previous build results. It also uses the -i option to obtain NEEDED and RUNPATH entries, which help detect changes in software dependencies and makes sure objects don't have any strange runpaths like /opt/SUNWspro/lib. checkproto Runs protocmp and protolist on a workspace (or uses the environment variable CODEMGR_WS to determine the workspace). Checks the proto area against the packages. codereview Given two filenames, creates a postscript file with the file differences highlighted. cscope-fast The fast version of cscope that we use internally. Seems to work, but may need more testing before it's placed in the gate. The source just really needs to be here. cstyle checks C source for compliance with OS/Net guidelines. ctfconvert Convert symbolic debugging information in an object file to the Compact ANSI-C Type Format (CTF). ctfdump Decode and display CTF data stored in a raw file or in an ELF file. ctfmerge Merge the CTF data from one or more object files. depcheck A tool to try an assess the dependencies of executables. This tool is not a definitive dependency check, but it does use "strings" and "ldd" to gather as much information as it can. The dependency check tool can handle filenames and pkgnames. Before using the dependency checker you must build a database which reflects the properties and files in your system. elfcmp Compares two ELF modules (e.g. .o files, executables) section by section. Useful for determining whether "trivial" changes - cstyle, lint, etc - actually changed the code. The -S option is used to test whether two binaries are the same except for the elfsign signature. elfsign Built from the same sources as the shipped elfsign(1), this version is used in nightly -t builds to assure that the signing process and format is the same as will be used on the target system. elfsigncmp This script can be used in lieu of elfsign during a build. It uses elfsign to sign a copy of the object and elfcmp -S to verify that the signing caused no damage before updating the object to be signed. findunref Finds all files in a source tree that have access times older than a certain time and are not in a specified list of exceptions. Since 'nightly' timestamps the start of the build, and findunref uses its timestamp (by default), this can be used to find all files that were unreferenced during a nightly build). Since some files are only used during a SPARC or Intel build, 'findunref' needs to be run on workspaces from both architectures and the results need to be merged. For instance, if $INTELSRC and $SPARCSRC are set to the usr/src directories of your Intel and SPARC nightly workspaces, then you can merge the results like so: $ findunref $INTELSRC $INTELSRC/tools/findunref/exception_list | \ sort > ~/unref-i386.out $ findunref $SPARCSRC $SPARCSRC/tools/findunref/exception_list | \ sort > ~/unref-sparc.out $ comm -12 ~/unref-i386.out ~/unref-sparc.out > ~/unref.out hdrchk checks headers for compliance with OS/Net standards (form, includes, C++ guards). install.bin binary version of /usr/sbin/install. Used to be vastly faster (since /usr/sbin/install is a shell script), but may only be a bit faster now. One speedup includes avoiding the name service for the well-known, never-changing password entries like 'root' and 'sys.' intf_check detects and reports ABI versioning and stability problems. lintdump dumps the contents of one or more lint libraries; see lintdump(1) keywords checks files for proper SCCS keywords. makebfu simple wrapper around 'mkbfu' for use outside nightly (when in a build shell from 'ws' or 'bldenv'). mkbfu makes cpio archives out of the proto area suitable for bfu'ing. Used by 'nightly' and 'makebfu'. nightly nightly build script. Takes an environment (or 'env') file describing such things as the workspace, the parent, and what to build. See env/developer and env/gatekeeper for sample, hopefully well-commented env files. pmodes enforces proper file ownership and permissions in pkgmap and package prototype* files. converts files if necessary protocmp compares proto lists and the package definitions. Used by nightly to determine if the proto area matches the packages, and to detect differences between a childs proto area and a parents. protocmp.terse transforms the output of protocmp into something a bit more friendly protolist create a list of what's in the proto area, to feed to protocmp. sccscp copy a file under SCCS control to another location in a workspace. also updates teamware's nametable. sccshist Display the history, comments and diffs, of a file under SCCS control. sccsmv rename a file under SCCS control to another location in a workspace. also updates teamware's nametable. sccsrm delete a file under SCCS control workspace. also updates teamware's nametable. Actually renames it to .del--`date` so that others will see it move when it is brought over (in case they were working on it). ws creates a shell with the environment set up to build in the given workspace. Used mostly for non-full-build workspaces, so it sets up to pull headers and libraries from the proto area of the parent if they aren't in the childs proto area. wx A great workspace tool by bonwick. See wx.README for information and warnings. tokenize Used to build the sun4u boot block. webrev Generates a set of HTML pages that show side-by-side diffs of changes in your workspace, for easy communication of code review materials. Can automagically find edited files or use a manually-generated list; knows how to use wx's active file for lists of checked-out files and proposed SCCS comments. How to do a full build ---------------------- 1. Find an environment file that might do what you want to do. If you're just a developer wanting to do a full build in a child of the gate, copy the 'developer' environment file to a new name (private to you and/or the work being done in this workspace, to avoid collisions with others). Then edit the file and tailor it to your workspace. Remember that this file is a shell script, so it can do more than set environment variables. 2. Login as 'gk' (or root, but your PATH and .make.machines for dmake will not be right). Run 'nightly' and give it your environment file as an option. 'nightly' will first look for your environment file in /opt/onbld/env, and if it's not there then it will look for it as an absolute or relative path. Some people put their environment files in their workspace to keep them close. 3. When 'nightly' is complete, it will send a summary of what happened to $MAILTO. Usually, the less info in the mail the better. If you have failures, you can go look at the full log of what happened, generally in $CODEMGR_WS/log/log./nightly.log (the mail_msg it sent and the proto list are there too). You can also find the individual build logs, like 'make clobber' and 'make install' output in $SRC, under names like clobber-${MACH}.out and install-${MACH}.out (for a DEBUG build). These will be smaller than nightly.log, and maybe more searchable. Files you have to update to add a tool -------------------------------------- 1. Add the tool in its appropriate place. 2. Update the Makefile as required. 3. Update usr/src/tools/SUNWonbld/prototype_*. 4. Update usr/src/tools/README.tools (this file). 5. Repeat 1-4 for any man pages.
