  23 .SH NAME
  24 .I nightly
  25 \- build an OS-Net consolidation overnight
  26 .SH SYNOPSIS
  27 \fBnightly [-in] [-V VERS] <env_file>\fP
  28 .LP
  29 .SH DESCRIPTION
  30 .IX "OS-Net build tools" "nightly" "" "\fBnightly\fP"
  31 .LP
  32 .I nightly,
  33 the mother of all build scripts,
  34 can bringover, build, archive, package, error check, and
  35 generally do everything it takes to
  36 turn OS/Net consolidation source code into useful stuff.
  37 It is customizable to permit you to run anything from a
  38 simple build to all of the cross-checking a gatekeeper
  39 needs.  The advantage to using
  40 .I nightly
  41 is that you build things correctly, consistently and
  42 automatically, with the best practices; building with
  43 .I nightly
  44 can mean never having to say you're sorry to your
  45 gatekeeper.
  46 .LP
  47 More
  48 specifically,
  49 .I nightly

 100 .LP
 101 The actions of the script are almost completely determined by
 102 the environment variables in the
 103 .I env
 104 file, the only necessary argument.  Ths only thing you really
 105 need to use 
 106 .I nightly
 107 is an
 108 .I env
 109 file that does what you want.
 110 .LP
 111 Like most of the other build tools in usr/src/tools, this script tends
 112 to change on a fairly regular basis; do not expect to be able to build
 113 OS/Net with a version of nightly significantly older than your source
 114 tree.  It has what is effectively a Consolidation Private relationship
 115 to other build tools and with many parts of the OS/Net makefiles,
 116 although it may also be used to build other consolidations.
 117 .LP
 118 .SH NIGHTLY_OPTIONS
 119 The environment variable NIGHTLY_OPTIONS controls the actions
 120 .I nightly
 121 will take as it proceeds.
 122 The -i, -n, +t and -V options may also be used from the command
 123 line to control the actions without editing your environment file.
 124 The -i and -n options complete the build more quickly by bypassing
 125 some actions. If NIGHTLY_OPTIONS is not set, then "-Bmt" build
 126 options will be used.
 127 
 128 .B Basic action options
 129 .TP 10
 130 .B \-D
 131 Do a build with DEBUG on (non-DEBUG is built by default)
 132 .TP
 133 .B \-F
 134 Do _not_ do a non-DEBUG build (use with -D to get just a DEBUG build)
 135 .TP
 136 .B \-M
 137 Do not run pmodes (safe file permission checker)
 138 .TP
 139 .B \-i
 140 Do an incremental build, suppressing the "make clobber" that by
 141 default removes all existing binaries and derived files.  From the
 142 command line, -i also suppresses the lint pass and the cstyle/hdrchk
 143 pass
 144 .TP
 145 .B \-n
 146 Suppress the bringover so that the build will start immediately with
 147 current source code
 148 .TP
 149 .B \-o
 150 Do an "old style" (pre-S10) build using root privileges to set OWNER
 151 and GROUP from the Makefiles.
 152 .TP
 153 .B \-p
 154 Create packages for regular install
 155 .TP
 156 .B \-U
 157 Update proto area in the parent workspace
 158 .TP
 159 .B \-u
 160 Update the parent workspace with files generated by the build, as follows.
 161 .RS
 162 .TP
 163 \(bu
 164 Copy proto_list_${MACH} and friends to usr/src in the parent.
 165 .TP
 166 \(bu
 167 When used with -f, build a usr/src/unrefmaster.out in
 168 the parent by merging all the usr/src/unref-${MACH}.out files in the
 169 parent.
 170 .TP
 171 \(bu
 172 When used with -A or -r, copy the contents of the resulting
 173 ELF-data.${MACH} directory to usr/src/ELF-data.${MACH} in the parent
 174 workspace.
 175 .RE
 176 .TP
 177 .B \-m
 178 Send mail to $MAILTO at end of build
 179 .TP
 180 .B \-t
 181 Build and use the tools in $SRC/tools (default setting).
 182 .TP
 183 .B \+t
 184 Use the build tools in "$ONBLD_TOOLS/bin".
 185 
 186 .LP
 187 .B Code checking options
 188 .TP 10
 189 .B \-A
 190 Check for ABI discrepancies in .so files.
 191 It is only required for shared object developers when there is an
 192 addition, deletion or change of interface in the .so files.
 193 .TP
 194 .B \-C
 195 Check for cstyle/hdrchk errors
 196 .TP
 197 .B \-f
 198 Check for unreferenced files.  Since the full workspace must be built
 199 in order to accurately identify unreferenced files, -f is ignored for
 200 incremental (-i) builds, or builds that do not include -l, and -p.
 201 .TP
 202 .B \-r
 203 Check the ELF runtime attributes of all dynamic objects
 204 .TP
 205 .B \-l
 206 Do "make lint" in $LINTDIRS (default: $SRC n)
 207 .TP
 208 .B \-N
 209 Do not run protocmp or checkpaths (note: this option is not
 210 recommended, especially in conjunction with the \-p option)
 211 .TP
 212 .B \-W
 213 Do not report warnings (for freeware gate ONLY)
 214 .TP
 215 .B \-w
 216 Report which proto area objects differ between this and the last build.
 217 See wsdiff(1) for details. Note that the proto areas used for comparison
 218 are the last ones constructed as part of the build. As an example, if both
 219 a non-debug and debug build are performed (in that order), then the debug
 220 proto area will be used for comparison (which might not be what you want).
 221 .LP
 222 .B Groups of options
 223 .TP 10

 234 .B Source Build options
 235 .TP 10
 236 .B \-S E | D | H
 237 Build the Export, Domestic, or Hybrid source product. Only Export and
 238 Domestic are truly buildable at this time.
 239 .TP 10
 240 .B \-S O
 241 Simulate an OpenSolaris build on a full tree.  This can be used by
 242 internal developers to ensure that they haven't broken the build for
 243 external developers.
 244 .LP
 245 Source build options only make sense for a full internal tree (open
 246 and closed source).  Only one source build option can be specified at
 247 a time.
 248 
 249 .LP
 250 .B Miscellaneous options
 251 .TP 10
 252 .B \-O
 253 generate deliverables for OpenSolaris.  Tarballs containing signed
 254 cryptographic binaries and binaries
 255 of closed-source components are put in $CODEMGR_WS.  (The
 256 cryptographic tarballs are copies of the
 257 ones that are put in the parent directory of
 258 $PKGARCHIVE.)
 259 .TP 10
 260 .B \-V VERS
 261 set the build version string to VERS, overriding VERSION
 262 .TP
 263 .B \-X
 264 Copies the proto area and packages from the IHV and IHV-bin gates into the
 265 nightly proto and package areas.  This is only available on i386.  See
 266 .B REALMODE ENVIRONMENT VARIABLES

 271 .LP
 272 .SH ENVIRONMENT VARIABLES
 273 .LP
 274 Here is a list of prominent environment variables that 
 275 .I nightly
 276 references and the meaning of each variable.
 277 .LP
 278 .RE
 279 .B CODEMGR_WS
 280 .RS 5
 281 The root of your workspace, including whatever metadata is kept by
 282 the source code management system.  This is the workspace in which the
 283 build will be done. 
 284 .RE
 285 .LP
 286 .B PARENT_WS
 287 .RS 5
 288 The root of the workspace that is the parent of the
 289 one being built.  This is particularly relevant for configurations
 290 with a main
 291 workspace and build workspaces underneath it; see the 
 292 \-u and \-U
 293 options as well as the PKGARCHIVE environment variable, for more
 294 information.
 295 .RE
 296 .LP
 297 .B BRINGOVER_WS
 298 .RS 5
 299 This is the workspace from which
 300 .I nightly
 301 will fetch sources to either populate or update your workspace;
 302 it defaults to $CLONE_WS.
 303 .RE
 304 .LP
 305 .B CLOSED_BRINGOVER_WS
 306 .RS 5
 307 A full Mercurial workspace has two repositories: one for open source
 308 and one for closed source.  If this variable is non-null, 
 309 .I nightly
 310 will pull from the repository that it names to get the closed source.
 311 It defaults to $CLOSED_CLONE_WS.
 312 .LP
 313 If $CODEMGR_WS already exists and contains only the open repository,
 314 .I nightly
 315 will ignore this variable; you'll need to pull the closed repository
 316 by hand if you want it.
 317 .RE
 318 .LP
 319 .B CLONE_WS
 320 .RS 5
 321 This is the workspace from which
 322 .I nightly
 323 will fetch sources by default.  This is
 324 often distinct from the parent, particularly if the parent is a gate.
 325 .RE
 326 .LP
 327 .B CLOSED_CLONE_WS
 328 .RS 5
 329 This is the default closed-source Mercurial repository that 
 330 .I nightly
 331 might pull from (see
 332 .B CLOSED_BRINGOVER_WS
 333 for details).
 334 .RE
 335 .LP
 336 .B SRC
 337 .RS 5
 338 Root of OS-Net source code, referenced by the Makefiles.  It is
 339 the starting point of build activity.  It should be expressed
 340 in terms of $CODEMGR_WS.
 341 .RE
 342 .LP
 343 .B ROOT
 344 .RS 5
 345 Root of the proto area for the build.  The makefiles direct
 346 installation of build products to this area and
 347 direct references to these files by builds of commands and other
 348 targets.  It should be expressed in terms of $CODEMGR_WS.
 349 .LP
 350 If $MULTI_PROTO is "no", $ROOT may contain a DEBUG or non-DEBUG
 351 build.  If $MULTI_PROTO is "yes", $ROOT contains the DEBUG build and
 352 $ROOT-nd contains the non-DEBUG build.
 353 .LP
 354 For OpenSolaris deliveries (\fB\-O\fR), $ROOT-closed contains a parallel
 355 proto area containing the DEBUG build of just usr/closed components, and
 356 $ROOT-nd-closed contains the non-DEBUG equivalent.
 357 .RE
 358 .LP
 359 .B TOOLS_ROOT
 360 .RS 5
 361 Root of the tools proto area for the build.  The makefiles direct
 362 installation of tools build products to this area.  Unless \fB+t\fR
 363 is part of $NIGHTLY_OPTIONS, these tools will be used during the
 364 build.
 365 .LP
 366 As built by nightly, this will always contain non-DEBUG objects.
 367 Therefore, this will always have a -nd suffix, regardless of
 368 $MULTI_PROTO.
 369 .RE
 370 .LP
 371 .B MACH
 372 .RS 5
 373 The instruction set architecture of the build machine as given
 374 by \fIuname -p\fP, e.g. sparc, i386.

 567 This is the path to a compressed tarball that contains debug
 568 cryptographic binaries that have been signed to allow execution
 569 outside of Sun, e.g., $PARENT_WS/packages/$MACH/on-crypto.$MACH.bz2.
 570 .I nightly
 571 will automatically adjust the path for non-debug builds.  This tarball
 572 is needed if the closed-source tree is not present.  Also, it is
 573 usually needed when generating OpenSolaris deliverables from a project
 574 workspace.  This is because most projects do not have access to the
 575 necessary key and certificate that would let them sign their own
