26This directory contains the tools used to do a full build of the
27OS/Net workspace.  They usually live in the /opt/onbld directory on build
28machines. From here, 'make install' will build and install the tools
29in $ROOT/opt/onbld. If you like, 'make pkg' will build the SUNWonbld
30package in $(PKGARCHIVE). Installing that package will populate the
31/opt/onbld directory, and create a root account for building called 'gk',
32which uses csh and has a home directory of /opt/onbld/gk. You can
33use this account to do full builds with 'nightly'. You don't have to,
34but the 'gk' account has the path setup properly, has a .make.machines
35file for dmake, and has a .login that sets up for dmake.

69Tool Summary
70------------
71
72bfu
73	bonwick/faulkner upgrade. Loads a set of cpio archives created
74	by 'mkbfu' onto a machine, either live or on alternate root
75	and /usr filesystems. Attempts to preserve important files,
76	but may require manual intervention before reboot to resolve
77	changes to preserved files.
78
79bfuld
80	Used by bfu to survive getting a new runtime linker when extracting
81	new cpio archives onto a live system. Patches binaries to use
82	a saved runtime linker in /tmp during the bfu process.
83	Not run by anything but bfu.
84
85bldenv
86	companion to 'nightly.' Takes the same environment file you
87	used with 'nightly,' and starts a shell with the environment
88	set up the same way as 'nightly' set it up. This is useful
89	if you're trying to quickly rebuild portions of a workspace
90	built by 'nightly'. 'ws' should not be used for this since it
91	sets the environment up differently and may cause everything
92	to rebuild (because of different -I or -L paths).
93
94build_cscope
95	builds cscope databases in the uts, the platform subdirectories
96	of uts, and in usr/src. Uses cscope-fast.
97
98cdm
99	A Mercurial extension providing various commands useful for ON
100	development
101
102check_rtime
103	checks ELF attributes used by ELF dynamic objects in the proto area.
104	Used by 'nightly's -r option, to check a number of ELF runtime
105	attributes for consistency with common build rules.  nightly uses
106	the -o option to simplify the output for diffing with previous
107	build results.  It also uses the -i option to obtain NEEDED and RUNPATH
108	entries, which help detect changes in software dependencies and makes
109	sure objects don't have any strange runpaths like /opt/SUNWspro/lib.
110
111checkproto
112	Runs protocmp and protolist on a workspace (or uses the environment
113	variable CODEMGR_WS to determine the workspace). Checks the proto area
114	against the packages.
115
116codereview
117	Given two filenames, creates a postscript file with the file
118	differences highlighted.
119
120codesign
121	Tools for signing cryptographic modules using the official
122	Sun release keys stored on a remote signing server. This
123	directory contains signit, a client program for signing
124	files with the signing server; signproto, a shell script
125	that finds crypto modules in $ROOT and signs them using
126	signit; and codesign_server.pl, the code that runs on the
127	server. The codesign_server code is not used on an ON
128	build machine but is kept here for source control purposes.
129
130copyrightchk
131	Checks that files have appropriate SMI copyright notices.
132	Primarily used by wx
133
134cscope-fast
135	The fast version of cscope that we use internally. Seems to work,
136	but may need more testing before it's placed in the gate. The source
137	just really needs to be here.
138
139cstyle
140	checks C source for compliance with OS/Net guidelines.
141
142ctfconvert
143	Convert symbolic debugging information in an object file to the Compact
144	ANSI-C Type Format (CTF).
145
146ctfdump
147	Decode and display CTF data stored in a raw file or in an ELF file.
148
149ctfmerge
150	Merge the CTF data from one or more object files.
151
152depcheck
153	A tool to try an assess the dependencies of executables.  This tool
154	is not a definitive dependency check, but it does use "strings" and
155	"ldd" to gather as much information as it can.  The dependency check
156	tool can handle filenames and pkgnames.  Before using the dependency
157	checker you must build a database which reflects the properties and
158	files in your system.
159
160elfcmp
161	Compares two ELF modules (e.g. .o files, executables) section by
162	section.  Useful for determining whether "trivial" changes -
163	cstyle, lint, etc - actually changed the code.  The -S option
164	is used to test whether two binaries are the same except for
165	the elfsign signature.
166
167elfsign
168	Built from the same sources as the shipped elfsign(1), this
169	version is used in nightly -t builds to assure that the signing
170	process and format is the same as will be used on the target
171	system.
172
173elfsigncmp
174	This script can be used in lieu of elfsign during a build.
175	It uses elfsign to sign a copy of the object and elfcmp -S to
176	verify that the signing caused no damage before updating
177	the object to be signed.
178
179find_elf
180	Search a directory tree for ELF objects, and produce one line of
181	output per object. Used by check_rtime and interface_check to locate
182	the objects to examine.
183
184findunref
185	Finds all files in a source tree that have access times older than a
186	certain time and are not in a specified list of exceptions.  Since
187	'nightly' timestamps the start of the build, and findunref uses its
188	timestamp (by default), this can be used to find all files that were
189	unreferenced during a nightly build).  Since some files are only used
190	during a SPARC or Intel build, 'findunref' needs to be run on
191	workspaces from both architectures and the results need to be merged.
192	For instance, if $INTELSRC and $SPARCSRC are set to the usr/src
193	directories of your Intel and SPARC nightly workspaces, then you
194	can merge the results like so:
195
196	$ findunref $INTELSRC $INTELSRC/tools/findunref/exception_list | \
197	  sort > ~/unref-i386.out
198	$ findunref $SPARCSRC $SPARCSRC/tools/findunref/exception_list | \
199	  sort > ~/unref-sparc.out
200	$ comm -12 ~/unref-i386.out ~/unref-sparc.out > ~/unref.out
201
202hdrchk
203	checks headers for compliance with OS/Net standards (form, includes,
204	C++ guards).
205
206hgsetup
207	creates a basic Mercurial configuration for the user.
208
209hg-active
210	helper used by webrev to generate file lists for Mercurial
211	workspaces.
212
213install.bin
214	binary version of /usr/sbin/install. Used to be vastly faster
215	(since /usr/sbin/install is a shell script), but may only be a bit
216	faster now. One speedup includes avoiding the name service for the
217	well-known, never-changing password entries like 'root' and 'sys.'
218
219interface_check
220	detects and reports invalid versioning in ELF objects.
221	Optionally generates an interface description file for
222	the workspace.
223
224interface_cmp
225	Compares two interface description files, as produced by
226	interface_check, and flags invalid deviations in ELF object
227	versioning between them. interface_cmp can be used between Solaris
228	gates to ensure that older releases remain compatible with the
229	development gate. It can also be used to validate new changes to
230	the development gate before they are integrated.
231
232lintdump
233	dumps the contents of one or more lint libraries; see lintdump(1)
234
235keywords
236	checks files for proper SCCS keywords.
237
238makebfu
239	simple wrapper around 'mkbfu' for use outside nightly (when in a build
240	shell from 'ws' or 'bldenv').
241
242mkbfu
243	makes cpio archives out of the proto area suitable for bfu'ing.
244	Used by 'nightly' and 'makebfu'.
245
246ndrgen
247	Network Data Language (NDL) RPC protocol compiler to support DCE
248	RPC/MSRPC and SMB/CIFS.  ndrgen takes an input protocol definition
249	file (say, proto.ndl) and generates an output C source file
250	(proto_ndr.c) containing the Network Data Representation (NDR)
251	marshalling routines to implement the RPC protocol.
252
253nightly
254	nightly build script. Takes an environment (or 'env') file describing
255	such things as the workspace, the parent, and what to build. See
256	env/developer and env/gatekeeper for sample, hopefully well-commented
257	env files.
258
259pmodes
260	enforces proper file ownership and permissions in pkgmap and package
261	prototype* files.  converts files if necessary
262
263protocmp
264	compares proto lists and the package definitions. Used by nightly
265	to determine if the proto area matches the packages, and to detect
266	differences between a childs proto area and a parents.
267
268protocmp.terse
269	transforms the output of protocmp into something a bit more friendly
270
271protolist
272	create a list of what's in the proto area, to feed to protocmp.
273
274rtichk
275	checks that a set of CRs have approved RTIs.  Primarily used
276	by wx
277
278sccscp
279	copy a file under SCCS control to another location in a workspace.
280	also updates teamware's nametable.
281
282sccshist
283	Display the history, comments and diffs, of a file under SCCS
284	control.
285
286sccsmv
287	rename a file under SCCS control to another location in a workspace.
288	also updates teamware's nametable.
289
290sccsrm
291	delete a file under SCCS control workspace. also updates teamware's
292	nametable. Actually renames it to .del-<file>-`date` so that others
293	will see it move when it is brought over (in case they were working
294	on it).
295
296ws
297	creates a shell with the environment set up to build in the given
298	workspace. Used mostly for non-full-build workspaces, so it sets up
299	to pull headers and libraries from the proto area of the parent if
300	they aren't in the childs proto area.
301
302wx
303	A great workspace tool by bonwick. See wx.README for information
304	and warnings.
305
306wx2hg
307	Converts a TeamWare workspace under the control of wx to a
308	Mercurial workspace, discarding intermediate deltas.
309
310tokenize
311	Used to build the sun4u boot block.
312
313webrev
314	Generates a set of HTML pages that show side-by-side diffs of
315	changes in your workspace, for easy communication of code
316	review materials.  Can automagically find edited files or use a
317	manually-generated list; knows how to use wx's active file for
318	lists of checked-out files and proposed SCCS comments.
319
320which_scm
321	Reports the current Source Code Management (SCM) system in use
322	and the top-level directory of the workspace.
323
324wsdiff
325	Detect object differences between two ON proto areas. Used by
326	nightly(1) to determine what changed between two builds. Handy
327	for identifying the set of built objects impacted by a given
328	source change. This information is needed for patch construction.
329
330
331How to do a full build
332----------------------
333
3341. Find an environment file that might do what you want to do. If you're just
335   a developer wanting to do a full build in a child of the gate, copy the
336   'developer' environment file to a new name (private to you and/or the
337   work being done in this workspace, to avoid collisions with others). Then
338   edit the file and tailor it to your workspace. Remember that this file
339   is a shell script, so it can do more than set environment variables.
340
3412. Login as 'gk' (or root, but your PATH and .make.machines for dmake will
342   not be right). Run 'nightly' and give it your environment file as an
343   option. 'nightly' will first look for your environment file in
344   /opt/onbld/env, and if it's not there then it will look for it as an
345   absolute or relative path. Some people put their environment files in
346   their workspace to keep them close.
347
3483. When 'nightly' is complete, it will send a summary of what happened to
349   $MAILTO. Usually, the less info in the mail the better. If you have failures,
350   you can go look at the full log of what happened, generally in
351   $CODEMGR_WS/log/log.<date>/nightly.log (the mail_msg it sent and the proto
352   list are there too). You can also find the individual build logs, like
353   'make clobber' and 'make install' output in $SRC, under names like
354   clobber-${MACH}.out and install-${MACH}.out (for a DEBUG build). These
355   will be smaller than nightly.log, and maybe more searchable.
356
357Files you have to update to add a tool
358--------------------------------------
359
3601.  Add the tool in its appropriate place.
3612.  Update the Makefile as required.
3623.  Update usr/src/tools/SUNWonbld/prototype_*.
3634.  Update usr/src/tools/README.tools (this file).
3645.  Repeat 1-4 for any man pages.
365
