28This directory contains the tools used to do a full build of the
29OS/Net workspace.  They usually live in the /opt/onbld directory on build
30machines. From here, 'make install' will build and install the tools
31in $ROOT/opt/onbld.
32

63Tool Summary
64------------
65
66bldenv
67	companion to 'nightly.' Takes the same environment file you
68	used with 'nightly,' and starts a shell with the environment
69	set up the same way as 'nightly' set it up. This is useful
70	if you're trying to quickly rebuild portions of a workspace
71	built by 'nightly'. 'ws' should not be used for this since it
72	sets the environment up differently and may cause everything
73	to rebuild (because of different -I or -L paths).
74
75build_cscope
76	builds cscope databases in the uts, the platform subdirectories
77	of uts, and in usr/src. Uses cscope-fast.
78
79check_rtime
80	checks ELF attributes used by ELF dynamic objects in the proto area.
81	Used by 'nightly's -r option, to check a number of ELF runtime
82	attributes for consistency with common build rules.  nightly uses
83	the -o option to simplify the output for diffing with previous
84	build results.  It also uses the -i option to obtain NEEDED and RUNPATH
85	entries, which help detect changes in software dependencies and makes
86	sure objects don't have any strange runpaths like /opt/SUNWspro/lib.
87
88codesign
89	Tools for signing cryptographic modules using the official
90	Sun release keys stored on a remote signing server. This
91	directory contains signit, a client program for signing
92	files with the signing server; signproto, a shell script
93	that finds crypto modules in $ROOT and signs them using
94	signit; and codesign_server.pl, the code that runs on the
95	server. The codesign_server code is not used on an ON
96	build machine but is kept here for source control purposes.
97
98copyrightchk
99	Checks that files have appropriate SMI copyright notices.
100	Primarily used by wx
101
102cscope-fast
103	The fast version of cscope that we use internally. Seems to work,
104	but may need more testing before it's placed in the gate. The source
105	just really needs to be here.
106
107cstyle
108	checks C source for compliance with OS/Net guidelines.
109
110ctfconvert
111	Convert symbolic debugging information in an object file to the Compact
112	ANSI-C Type Format (CTF).
113
114ctfdump
115	Decode and display CTF data stored in a raw file or in an ELF file.
116
117ctfmerge
118	Merge the CTF data from one or more object files.
119
120elfcmp
121	Compares two ELF modules (e.g. .o files, executables) section by
122	section.  Useful for determining whether "trivial" changes -
123	cstyle, lint, etc - actually changed the code.  The -S option
124	is used to test whether two binaries are the same except for
125	the elfsign signature.
126
127find_elf
128	Search a directory tree for ELF objects, and produce one line of
129	output per object. Used by check_rtime and interface_check to locate
130	the objects to examine.
131
132findunref
133	Finds all files in a source tree that have access times older than a
134	certain time and are not in a specified list of exceptions.  Since
135	'nightly' timestamps the start of the build, and findunref uses its
136	timestamp (by default), this can be used to find all files that were
137	unreferenced during a nightly build).  Since some files are only used
138	during a SPARC or Intel build, 'findunref' needs to be run on
139	workspaces from both architectures and the results need to be merged.
140	For instance, if $INTELSRC and $SPARCSRC are set to the usr/src
141	directories of your Intel and SPARC nightly workspaces, then you
142	can merge the results like so:
143
144	$ findunref $INTELSRC $INTELSRC/tools/findunref/exception_list | \
145	  sort > ~/unref-i386.out
146	$ findunref $SPARCSRC $SPARCSRC/tools/findunref/exception_list | \
147	  sort > ~/unref-sparc.out
148	$ comm -12 ~/unref-i386.out ~/unref-sparc.out > ~/unref.out
149
150hdrchk
151	checks headers for compliance with OS/Net standards (form, includes,
152	C++ guards).
153
154install.bin
155	binary version of /usr/sbin/install. Used to be vastly faster
156	(since /usr/sbin/install is a shell script), but may only be a bit
157	faster now. One speedup includes avoiding the name service for the
158	well-known, never-changing password entries like 'root' and 'sys.'
159
160interface_check
161	detects and reports invalid versioning in ELF objects.
162	Optionally generates an interface description file for
163	the workspace.
164
165interface_cmp
166	Compares two interface description files, as produced by
167	interface_check, and flags invalid deviations in ELF object
168	versioning between them. interface_cmp can be used between Solaris
169	gates to ensure that older releases remain compatible with the
170	development gate. It can also be used to validate new changes to
171	the development gate before they are integrated.
172
173lintdump
174	dumps the contents of one or more lint libraries; see lintdump(1)
175
176ndrgen
177	Network Data Language (NDL) RPC protocol compiler to support DCE
178	RPC/MSRPC and SMB/CIFS.  ndrgen takes an input protocol definition
179	file (say, proto.ndl) and generates an output C source file
180	(proto_ndr.c) containing the Network Data Representation (NDR)
181	marshalling routines to implement the RPC protocol.
182
183nightly
184	nightly build script. Takes an environment (or 'env') file describing
185	such things as the workspace, the parent, and what to build. See
186	env/developer and env/gatekeeper for sample, hopefully well-commented
187	env files.
188
189protocmp
190	compares proto lists and the package definitions. Used by nightly
191	to determine if the proto area matches the packages, and to detect
192	differences between a childs proto area and a parents.
193
194protocmp.terse
195	transforms the output of protocmp into something a bit more friendly
196
197protolist
198	create a list of what's in the proto area, to feed to protocmp.
199
200
201ws
202	creates a shell with the environment set up to build in the given
203	workspace. Used mostly for non-full-build workspaces, so it sets up
204	to pull headers and libraries from the proto area of the parent if
205	they aren't in the childs proto area.
206
207tokenize
208	Used to build the sun4u boot block.
209
210webrev
211	Generates a set of HTML pages that show side-by-side diffs of
212	changes in your workspace, for easy communication of code
213	review materials.  Can automagically find edited files or use a
214	manually-generated list; knows how to use wx's active file for
215	lists of checked-out files and proposed SCCS comments.
216
217which_scm
218	Reports the current Source Code Management (SCM) system in use
219	and the top-level directory of the workspace.
220
221wsdiff
222	Detect object differences between two ON proto areas. Used by
223	nightly(1) to determine what changed between two builds. Handy
224	for identifying the set of built objects impacted by a given
225	source change. This information is needed for patch construction.
226
227
228How to do a full build
229----------------------
230
2311. Find an environment file that might do what you want to do. If you're just
232   a developer wanting to do a full build in a child of the gate, copy the
233   'developer' environment file to a new name (private to you and/or the
234   work being done in this workspace, to avoid collisions with others). Then
235   edit the file and tailor it to your workspace. Remember that this file
236   is a shell script, so it can do more than set environment variables.
237
2382. Run 'nightly' and give it your environment file as an
239   option. 'nightly' will first look for your environment file in
240   /opt/onbld/env, and if it's not there then it will look for it as an
241   absolute or relative path. Some people put their environment files in
242   their workspace to keep them close.
243
2443. When 'nightly' is complete, it will send a summary of what happened to
245   $MAILTO. Usually, the less info in the mail the better. If you have failures,
246   you can go look at the full log of what happened, generally in
247   $CODEMGR_WS/log/log.<date>/nightly.log (the mail_msg it sent and the proto
248   list are there too). You can also find the individual build logs, like
249   'make clobber' and 'make install' output in $SRC, under names like
250   clobber-${MACH}.out and install-${MACH}.out (for a DEBUG build). These
251   will be smaller than nightly.log, and maybe more searchable.
252
253Files you have to update to add a tool
254--------------------------------------
255
2561.  Add the tool in its appropriate place.
2572.  Update the Makefile as required.
2583.  Update usr/src/pkg/manifests/developer-build-onbld.p5m
2594.  Update usr/src/tools/README.tools (this file).
2605.  Repeat 1-4 for any man pages.
