They usually live in the /opt/onbld directory on build 29machines. From here, 'make install' will build and install the tools 30in $ROOT/opt/onbld. If you like, 'make pkg' will build the SUNWonbld 31package in $(PKGARCHIVE). Installing that package will populate the 32/opt/onbld directory, and create a root account for building called 'gk', 33which uses csh and has a home directory of /opt/onbld/gk. You can 34use this account to do full builds with 'nightly'. You don't have to, 35but the 'gk' account has the path setup properly, has a .make.machines 36file for dmake, and has a .login that sets up for dmake. 37 38Layout of /opt/onbld 39-------------------- 40 41/opt/onbld/etc/abi 42 contains Solaris ABI database (ABI_*.db) and exceptions 43 for ABI Auditing tool (intf_check). 44 45/opt/onbld/gk 46 gk account's home directory. 47 48/opt/onbld/bin 49 basic bin directory - contains scripts. 50 51/opt/onbld/bin/${MACH} 52 architecture-specific bin directory for binaries. 53 54/opt/onbld/env 55 build environment files. 56 57/opt/onbld/man 58 rudimentary man pages for some of the tools. 59 60 61Tool Summary 62------------ 63 64bfu 65 bonwick/faulkner upgrade. Loads a set of cpio archives created 66 by 'mkbfu' onto a machine, either live or on alternate root 67 and /usr filesystems. Attempts to preserve important files, 68 but may require manual intervention before reboot to resolve 69 changes to preserved files. 70 71bfuld 72 Used by bfu to survive getting a new runtime linker when extracting 73 new cpio archives onto a live system. Patches binaries to use 74 a saved runtime linker in /tmp during the bfu process. 75 Not run by anything but bfu. 76 77bldenv 78 companion to 'nightly.' Takes the same environment file you 79 used with 'nightly,' and starts a shell with the environment 80 set up the same way as 'nightly' set it up. This is useful 81 if you're trying to quickly rebuild portions of a workspace 82 built by 'nightly'. 'ws' should not be used for this since it 83 sets the environment up differently and may cause everything 84 to rebuild (because of different -I or -L paths). 85 86build_cscope 87 88 builds cscope databases in the uts, the platform subdirectories 89 of uts, and in usr/src. Uses cscope-fast. 90 91check_rtime 92 93 checks ELF attributes used by ELF dynamic objects in the proto area. 94 Used by 'nightly's -r option, to check a number of ELF runtime 95 attributes for consistency with common build rules. nightly uses 96 the -o option to simplify the output for diffing with previous 97 build results. It also uses the -i option to obtain NEEDED and RUNPATH 98 entries, which help detect changes in software dependencies and makes 99 sure objects don't have any strange runpaths like /opt/SUNWspro/lib. 100 101checkproto 102 103 Runs protocmp and protolist on a workspace (or uses the environment 104 variable CODEMGR_WS to determine the workspace). Checks the proto area 105 against the packages. 106 107codereview 108 109 Given two filenames, creates a postscript file with the file 110 differences highlighted. 111 112cscope-fast 113 The fast version of cscope that we use internally. Seems to work, 114 but may need more testing before it's placed in the gate. The source 115 just really needs to be here. 116 117cstyle 118 checks C source for compliance with OS/Net guidelines. 119 120ctfconvert 121 Convert symbolic debugging information in an object file to the Compact 122 ANSI-C Type Format (CTF). 123 124ctfdump 125 Decode and display CTF data stored in a raw file or in an ELF file. 126 127ctfmerge 128 Merge the CTF data from one or more object files. 129 130depcheck 131 A tool to try an assess the dependencies of executables. This tool 132 is not a definitive dependency check, but it does use "strings" and 133 "ldd" to gather as much information as it can. The dependency check 134 tool can handle filenames and pkgnames. Before using the dependency 135 checker you must build a database which reflects the properties and 136 files in your system. 137 138elfcmp 139 Compares two ELF modules (e.g. .o files, executables) section by 140 section. Useful for determining whether "trivial" changes - 141 cstyle, lint, etc - actually changed the code. The -S option 142 is used to test whether two binaries are the same except for 143 the elfsign signature. 144 145elfsign 146 Built from the same sources as the shipped elfsign(1), this 147 version is used in nightly -t builds to assure that the signing 148 process and format is the same as will be used on the target 149 system. 150 151elfsigncmp 152 This script can be used in lieu of elfsign during a build. 153 It uses elfsign to sign a copy of the object and elfcmp -S to 154 verify that the signing caused no damage before updating 155 the object to be signed. 156 157findunref 158 Finds all files in a source tree that have access times older than a 159 certain time and are not in a specified list of exceptions. Since 160 'nightly' timestamps the start of the build, and findunref uses its 161 timestamp (by default), this can be used to find all files that were 162 unreferenced during a nightly build). Since some files are only used 163 during a SPARC or Intel build, 'findunref' needs to be run on 164 workspaces from both architectures and the results need to be merged. 165 For instance, if $INTELSRC and $SPARCSRC are set to the usr/src 166 directories of your Intel and SPARC nightly workspaces, then you 167 can merge the results like so: 168 169 $ findunref $INTELSRC $INTELSRC/tools/findunref/exception_list | \ 170 sort > ~/unref-i386.out 171 $ findunref $SPARCSRC $SPARCSRC/tools/findunref/exception_list | \ 172 sort > ~/unref-sparc.out 173 $ comm -12 ~/unref-i386.out ~/unref-sparc.out > ~/unref.out 174 175hdrchk 176 checks headers for compliance with OS/Net standards (form, includes, 177 C++ guards). 178 179install.bin 180 binary version of /usr/sbin/install. Used to be vastly faster 181 (since /usr/sbin/install is a shell script), but may only be a bit 182 faster now. One speedup includes avoiding the name service for the 183 well-known, never-changing password entries like 'root' and 'sys.' 184 185intf_check 186 detects and reports ABI versioning and stability problems. 187 188lintdump 189 dumps the contents of one or more lint libraries; see lintdump(1) 190 191keywords 192 checks files for proper SCCS keywords. 193 194makebfu 195 simple wrapper around 'mkbfu' for use outside nightly (when in a build 196 shell from 'ws' or 'bldenv'). 197 198mkbfu 199 makes cpio archives out of the proto area suitable for bfu'ing. 200 Used by 'nightly' and 'makebfu'. 201 202nightly 203 nightly build script. Takes an environment (or 'env') file describing 204 such things as the workspace, the parent, and what to build. See 205 env/developer and env/gatekeeper for sample, hopefully well-commented 206 env files. 207 208pmodes 209 enforces proper file ownership and permissions in pkgmap and package 210 prototype* files. converts files if necessary 211 212protocmp 213 compares proto lists and the package definitions. Used by nightly 214 to determine if the proto area matches the packages, and to detect 215 differences between a childs proto area and a parents. 216 217protocmp.terse 218 transforms the output of protocmp into something a bit more friendly 219 220protolist 221 create a list of what's in the proto area, to feed to protocmp. 222 223sccscp 224 copy a file under SCCS control to another location in a workspace. 225 also updates teamware's nametable. 226 227sccshist 228 Display the history, comments and diffs, of a file under SCCS 229 control. 230 231sccsmv 232 rename a file under SCCS control to another location in a workspace. 233 also updates teamware's nametable. 234 235sccsrm 236 delete a file under SCCS control workspace. also updates teamware's 237 nametable. Actually renames it to .del-<file>-`date` so that others 238 will see it move when it is brought over (in case they were working 239 on it). 240 241ws 242 creates a shell with the environment set up to build in the given 243 workspace. Used mostly for non-full-build workspaces, so it sets up 244 to pull headers and libraries from the proto area of the parent if 245 they aren't in the childs proto area. 246 247wx 248 A great workspace tool by bonwick. See wx.README for information 249 and warnings. 250 251tokenize 252 Used to build the sun4u boot block. 253 254webrev 255 Generates a set of HTML pages that show side-by-side diffs of 256 changes in your workspace, for easy communication of code 257 review materials. Can automagically find edited files or use a 258 manually-generated list; knows how to use wx's active file for 259 lists of checked-out files and proposed SCCS comments. 260 261wsdiff 262 Detect object differences between two ON proto areas. Used by 263 nightly(1) to determine what changed between two builds. Handy 264 for identifying the set of built objects impacted by a given 265 source change. This information is needed for patch construction. 266 267 268How to do a full build 269---------------------- 270 2711. Find an environment file that might do what you want to do. If you're just 272 a developer wanting to do a full build in a child of the gate, copy the 273 'developer' environment file to a new name (private to you and/or the 274 work being done in this workspace, to avoid collisions with others). Then 275 edit the file and tailor it to your workspace. Remember that this file 276 is a shell script, so it can do more than set environment variables. 277 2782. Login as 'gk' (or root, but your PATH and .make.machines for dmake will 279 not be right). Run 'nightly' and give it your environment file as an 280 option. 'nightly' will first look for your environment file in 281 /opt/onbld/env, and if it's not there then it will look for it as an 282 absolute or relative path. Some people put their environment files in 283 their workspace to keep them close. 284 2853. When 'nightly' is complete, it will send a summary of what happened to 286 $MAILTO. Usually, the less info in the mail the better. If you have failures, 287 you can go look at the full log of what happened, generally in 288 $CODEMGR_WS/log/log.<date>/nightly.log (the mail_msg it sent and the proto 289 list are there too). You can also find the individual build logs, like 290 'make clobber' and 'make install' output in $SRC, under names like 291 clobber-${MACH}.out and install-${MACH}.out (for a DEBUG build). These 292 will be smaller than nightly.log, and maybe more searchable. 293 294Files you have to update to add a tool 295-------------------------------------- 296 2971. Add the tool in its appropriate place. 2982. Update the Makefile as required. 2993. Update usr/src/tools/SUNWonbld/prototype_*. 3004. Update usr/src/tools/README.tools (this file). 3015. Repeat 1-4 for any man pages. 302
