All rights reserved. 23 24 25This directory contains the tools used to do a full build of the 26OS/Net workspace. They usually live in the /opt/onbld directory on build 27machines. From here, 'make install' will build and install the tools 28in $ROOT/opt/onbld. If you like, 'make pkg' will build the SUNWonbld 29package in $(PKGARCHIVE). Installing that package will populate the 30/opt/onbld directory, and create a root account for building called 'gk', 31which uses csh and has a home directory of /opt/onbld/gk. You can 32use this account to do full builds with 'nightly'. You don't have to, 33but the 'gk' account has the path setup properly, has a .make.machines 34file for dmake, and has a .login that sets up for dmake. 35 36Layout of /opt/onbld 37-------------------- 38 39/opt/onbld/etc/abi 40 contains Solaris ABI database (ABI_*.db) and exceptions 41 for ABI Auditing tool (interface_check, interface_cmp). 42 43/opt/onbld/gk 44 gk account's home directory. 45 46/opt/onbld/bin 47 basic bin directory - contains scripts. 48 49/opt/onbld/bin/${MACH} 50 architecture-specific bin directory for binaries. 51 52/opt/onbld/env 53 build environment files. 54 55/opt/onbld/lib 56 libraries used by the build tools. 57 58/opt/onbld/lib/python<version>/ 59 python modules used by the build tools. 60 61/opt/onbld/lib/python<version>/onbld/hgext 62 Mercurial extensions. 63 64/opt/onbld/lib/python/ 65 symlink to the modules directory of the currently preferred 66 python version. This exists to retain compatibility both for 67 tools expecting only one supported version of python, and for 68 user .hgrc files that expect to find cdm.py in 69 /opt/onbld/lib/python/onbld/hgext. 70 71/opt/onbld/man 72 rudimentary man pages for some of the tools. 73 74 75Tool Summary 76------------ 77 78bldenv 79 companion to 'nightly.' Takes the same environment file you 80 used with 'nightly,' and starts a shell with the environment 81 set up the same way as 'nightly' set it up. This is useful 82 if you're trying to quickly rebuild portions of a workspace 83 built by 'nightly'. 'ws' should not be used for this since it 84 sets the environment up differently and may cause everything 85 to rebuild (because of different -I or -L paths). 86 87build_cscope 88 builds cscope databases in the uts, the platform subdirectories 89 of uts, and in usr/src. Uses cscope-fast. 90 91cdm 92 A Mercurial extension providing various commands useful for ON 93 development 94 95check_rtime 96 checks ELF attributes used by ELF dynamic objects in the proto area. 97 Used by 'nightly's -r option, to check a number of ELF runtime 98 attributes for consistency with common build rules. nightly uses 99 the -o option to simplify the output for diffing with previous 100 build results. It also uses the -i option to obtain NEEDED and RUNPATH 101 entries, which help detect changes in software dependencies and makes 102 sure objects don't have any strange runpaths like /opt/SUNWspro/lib. 103 104checkproto 105 Runs protocmp and protolist on a workspace (or uses the environment 106 variable CODEMGR_WS to determine the workspace). Checks the proto area 107 against the packages. 108 109codereview 110 Given two filenames, creates a postscript file with the file 111 differences highlighted. 112 113codesign 114 Tools for signing cryptographic modules using the official 115 Sun release keys stored on a remote signing server. This 116 directory contains signit, a client program for signing 117 files with the signing server; signproto, a shell script 118 that finds crypto modules in $ROOT and signs them using 119 signit; and codesign_server.pl, the code that runs on the 120 server. The codesign_server code is not used on an ON 121 build machine but is kept here for source control purposes. 122 123copyrightchk 124 Checks that files have appropriate SMI copyright notices. 125 Primarily used by wx 126 127cscope-fast 128 The fast version of cscope that we use internally. Seems to work, 129 but may need more testing before it's placed in the gate. The source 130 just really needs to be here. 131 132cstyle 133 checks C source for compliance with OS/Net guidelines. 134 135ctfconvert 136 Convert symbolic debugging information in an object file to the Compact 137 ANSI-C Type Format (CTF). 138 139ctfdump 140 Decode and display CTF data stored in a raw file or in an ELF file. 141 142ctfmerge 143 Merge the CTF data from one or more object files. 144 145depcheck 146 A tool to try an assess the dependencies of executables. This tool 147 is not a definitive dependency check, but it does use "strings" and 148 "ldd" to gather as much information as it can. The dependency check 149 tool can handle filenames and pkgnames. Before using the dependency 150 checker you must build a database which reflects the properties and 151 files in your system. 152 153elfcmp 154 Compares two ELF modules (e.g. .o files, executables) section by 155 section. Useful for determining whether "trivial" changes - 156 cstyle, lint, etc - actually changed the code. The -S option 157 is used to test whether two binaries are the same except for 158 the elfsign signature. 159 160find_elf 161 Search a directory tree for ELF objects, and produce one line of 162 output per object. Used by check_rtime and interface_check to locate 163 the objects to examine. 164 165findunref 166 Finds all files in a source tree that have access times older than a 167 certain time and are not in a specified list of exceptions. Since 168 'nightly' timestamps the start of the build, and findunref uses its 169 timestamp (by default), this can be used to find all files that were 170 unreferenced during a nightly build). Since some files are only used 171 during a SPARC or Intel build, 'findunref' needs to be run on 172 workspaces from both architectures and the results need to be merged. 173 For instance, if $INTELSRC and $SPARCSRC are set to the usr/src 174 directories of your Intel and SPARC nightly workspaces, then you 175 can merge the results like so: 176 177 $ findunref $INTELSRC $INTELSRC/tools/findunref/exception_list | \ 178 sort > ~/unref-i386.out 179 $ findunref $SPARCSRC $SPARCSRC/tools/findunref/exception_list | \ 180 sort > ~/unref-sparc.out 181 $ comm -12 ~/unref-i386.out ~/unref-sparc.out > ~/unref.out 182 183hdrchk 184 checks headers for compliance with OS/Net standards (form, includes, 185 C++ guards). 186 187hgsetup 188 creates a basic Mercurial configuration for the user. 189 190hg-active 191 helper used by webrev to generate file lists for Mercurial 192 workspaces. 193 194install.bin 195 binary version of /usr/sbin/install. Used to be vastly faster 196 (since /usr/sbin/install is a shell script), but may only be a bit 197 faster now. One speedup includes avoiding the name service for the 198 well-known, never-changing password entries like 'root' and 'sys.' 199 200interface_check 201 detects and reports invalid versioning in ELF objects. 202 Optionally generates an interface description file for 203 the workspace. 204 205interface_cmp 206 Compares two interface description files, as produced by 207 interface_check, and flags invalid deviations in ELF object 208 versioning between them. interface_cmp can be used between Solaris 209 gates to ensure that older releases remain compatible with the 210 development gate. It can also be used to validate new changes to 211 the development gate before they are integrated. 212 213lintdump 214 dumps the contents of one or more lint libraries; see lintdump(1) 215 216ndrgen 217 Network Data Language (NDL) RPC protocol compiler to support DCE 218 RPC/MSRPC and SMB/CIFS. ndrgen takes an input protocol definition 219 file (say, proto.ndl) and generates an output C source file 220 (proto_ndr.c) containing the Network Data Representation (NDR) 221 marshalling routines to implement the RPC protocol. 222 223nightly 224 nightly build script. Takes an environment (or 'env') file describing 225 such things as the workspace, the parent, and what to build. See 226 env/developer and env/gatekeeper for sample, hopefully well-commented 227 env files. 228 229pmodes 230 enforces proper file ownership and permissions in pkgmap and package 231 prototype* files. converts files if necessary 232 233protocmp 234 compares proto lists and the package definitions. Used by nightly 235 to determine if the proto area matches the packages, and to detect 236 differences between a childs proto area and a parents. 237 238protocmp.terse 239 transforms the output of protocmp into something a bit more friendly 240 241protolist 242 create a list of what's in the proto area, to feed to protocmp. 243 244 245ws 246 creates a shell with the environment set up to build in the given 247 workspace. Used mostly for non-full-build workspaces, so it sets up 248 to pull headers and libraries from the proto area of the parent if 249 they aren't in the childs proto area. 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 261which_scm 262 Reports the current Source Code Management (SCM) system in use 263 and the top-level directory of the workspace. 264 265wsdiff 266 Detect object differences between two ON proto areas. Used by 267 nightly(1) to determine what changed between two builds. Handy 268 for identifying the set of built objects impacted by a given 269 source change. This information is needed for patch construction. 270 271 272How to do a full build 273---------------------- 274 2751. Find an environment file that might do what you want to do. If you're just 276 a developer wanting to do a full build in a child of the gate, copy the 277 'developer' environment file to a new name (private to you and/or the 278 work being done in this workspace, to avoid collisions with others). Then 279 edit the file and tailor it to your workspace. Remember that this file 280 is a shell script, so it can do more than set environment variables. 281 2822. Login as 'gk' (or root, but your PATH and .make.machines for dmake will 283 not be right). Run 'nightly' and give it your environment file as an 284 option. 'nightly' will first look for your environment file in 285 /opt/onbld/env, and if it's not there then it will look for it as an 286 absolute or relative path. Some people put their environment files in 287 their workspace to keep them close. 288 2893. When 'nightly' is complete, it will send a summary of what happened to 290 $MAILTO. Usually, the less info in the mail the better. If you have failures, 291 you can go look at the full log of what happened, generally in 292 $CODEMGR_WS/log/log.<date>/nightly.log (the mail_msg it sent and the proto 293 list are there too). You can also find the individual build logs, like 294 'make clobber' and 'make install' output in $SRC, under names like 295 clobber-${MACH}.out and install-${MACH}.out (for a DEBUG build). These 296 will be smaller than nightly.log, and maybe more searchable. 297 298Files you have to update to add a tool 299-------------------------------------- 300 3011. Add the tool in its appropriate place. 3022. Update the Makefile as required. 3033. Update usr/src/pkg/manifests/developer-build-onbld.mf 3044. Update usr/src/tools/README.tools (this file). 3055. Repeat 1-4 for any man pages. 306
