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.

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.

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
