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.

60Tool Summary
61------------
62
63bldenv
64	companion to 'nightly.' Takes the same environment file you
65	used with 'nightly,' and starts a shell with the environment
66	set up the same way as 'nightly' set it up. This is useful
67	if you're trying to quickly rebuild portions of a workspace
68	built by 'nightly'. 'ws' should not be used for this since it
69	sets the environment up differently and may cause everything
70	to rebuild (because of different -I or -L paths).
71
72build_cscope
73	builds cscope databases in the uts, the platform subdirectories
74	of uts, and in usr/src. Uses cscope-fast.
75
76check_rtime
77	checks ELF attributes used by ELF dynamic objects in the proto area.
78	Used by 'nightly's -r option, to check a number of ELF runtime
79	attributes for consistency with common build rules.  nightly uses
80	the -o option to simplify the output for diffing with previous
81	build results.  It also uses the -i option to obtain NEEDED and RUNPATH
82	entries, which help detect changes in software dependencies and makes
83	sure objects don't have any strange runpaths like /opt/SUNWspro/lib.
84
85codereview
86	Given two filenames, creates a postscript file with the file
87	differences highlighted.
88
89codesign
90	Tools for signing cryptographic modules using the official
91	Sun release keys stored on a remote signing server. This
92	directory contains signit, a client program for signing
93	files with the signing server; signproto, a shell script
94	that finds crypto modules in $ROOT and signs them using
95	signit; and codesign_server.pl, the code that runs on the
96	server. The codesign_server code is not used on an ON
97	build machine but is kept here for source control purposes.
98
99copyrightchk
100	Checks that files have appropriate SMI copyright notices.
101	Primarily used by wx
102
103cscope-fast
104	The fast version of cscope that we use internally. Seems to work,
105	but may need more testing before it's placed in the gate. The source
106	just really needs to be here.
107
108cstyle
109	checks C source for compliance with OS/Net guidelines.
110
111ctfconvert
112	Convert symbolic debugging information in an object file to the Compact
113	ANSI-C Type Format (CTF).
114
115ctfdump
116	Decode and display CTF data stored in a raw file or in an ELF file.
117
118ctfmerge
119	Merge the CTF data from one or more object files.
120
121elfcmp
122	Compares two ELF modules (e.g. .o files, executables) section by
123	section.  Useful for determining whether "trivial" changes -
124	cstyle, lint, etc - actually changed the code.  The -S option
125	is used to test whether two binaries are the same except for
126	the elfsign signature.
127
128find_elf
129	Search a directory tree for ELF objects, and produce one line of
130	output per object. Used by check_rtime and interface_check to locate
131	the objects to examine.
132
133findunref
134	Finds all files in a source tree that have access times older than a
135	certain time and are not in a specified list of exceptions.  Since
136	'nightly' timestamps the start of the build, and findunref uses its
137	timestamp (by default), this can be used to find all files that were
138	unreferenced during a nightly build).  Since some files are only used
139	during a SPARC or Intel build, 'findunref' needs to be run on
140	workspaces from both architectures and the results need to be merged.
141	For instance, if $INTELSRC and $SPARCSRC are set to the usr/src
142	directories of your Intel and SPARC nightly workspaces, then you
143	can merge the results like so:
144
145	$ findunref $INTELSRC $INTELSRC/tools/findunref/exception_list | \
146	  sort > ~/unref-i386.out
147	$ findunref $SPARCSRC $SPARCSRC/tools/findunref/exception_list | \
148	  sort > ~/unref-sparc.out
149	$ comm -12 ~/unref-i386.out ~/unref-sparc.out > ~/unref.out
150
151hdrchk
152	checks headers for compliance with OS/Net standards (form, includes,
153	C++ guards).
154
155install.bin
156	binary version of /usr/sbin/install. Used to be vastly faster
157	(since /usr/sbin/install is a shell script), but may only be a bit
158	faster now. One speedup includes avoiding the name service for the
159	well-known, never-changing password entries like 'root' and 'sys.'
160
161interface_check
162	detects and reports invalid versioning in ELF objects.
163	Optionally generates an interface description file for
164	the workspace.
165
166interface_cmp
167	Compares two interface description files, as produced by
168	interface_check, and flags invalid deviations in ELF object
169	versioning between them. interface_cmp can be used between Solaris
170	gates to ensure that older releases remain compatible with the
171	development gate. It can also be used to validate new changes to
172	the development gate before they are integrated.
173
174lintdump
175	dumps the contents of one or more lint libraries; see lintdump(1)
176
177ndrgen
178	Network Data Language (NDL) RPC protocol compiler to support DCE
179	RPC/MSRPC and SMB/CIFS.  ndrgen takes an input protocol definition
180	file (say, proto.ndl) and generates an output C source file
181	(proto_ndr.c) containing the Network Data Representation (NDR)
182	marshalling routines to implement the RPC protocol.
183
184nightly
185	nightly build script. Takes an environment (or 'env') file describing
186	such things as the workspace, the parent, and what to build. See
187	env/developer and env/gatekeeper for sample, hopefully well-commented
188	env files.
189
190protocmp
191	compares proto lists and the package definitions. Used by nightly
192	to determine if the proto area matches the packages, and to detect
193	differences between a childs proto area and a parents.
194
195protocmp.terse
196	transforms the output of protocmp into something a bit more friendly
197
198protolist
199	create a list of what's in the proto area, to feed to protocmp.
200
201
202ws
203	creates a shell with the environment set up to build in the given
204	workspace. Used mostly for non-full-build workspaces, so it sets up
205	to pull headers and libraries from the proto area of the parent if
206	they aren't in the childs proto area.
207
208tokenize
209	Used to build the sun4u boot block.
210
211webrev
212	Generates a set of HTML pages that show side-by-side diffs of
213	changes in your workspace, for easy communication of code
214	review materials.  Can automagically find edited files or use a
215	manually-generated list; knows how to use wx's active file for
216	lists of checked-out files and proposed SCCS comments.
217
218which_scm
219	Reports the current Source Code Management (SCM) system in use
220	and the top-level directory of the workspace.
221
222wsdiff
223	Detect object differences between two ON proto areas. Used by
224	nightly(1) to determine what changed between two builds. Handy
225	for identifying the set of built objects impacted by a given
226	source change. This information is needed for patch construction.
227
228
229How to do a full build
230----------------------
231
2321. Find an environment file that might do what you want to do. If you're just
233   a developer wanting to do a full build in a child of the gate, copy the
234   'developer' environment file to a new name (private to you and/or the
235   work being done in this workspace, to avoid collisions with others). Then
236   edit the file and tailor it to your workspace. Remember that this file
237   is a shell script, so it can do more than set environment variables.
238
2392. Run 'nightly' and give it your environment file as an
240   option. 'nightly' will first look for your environment file in
241   /opt/onbld/env, and if it's not there then it will look for it as an
242   absolute or relative path. Some people put their environment files in
243   their workspace to keep them close.
244
2453. When 'nightly' is complete, it will send a summary of what happened to
246   $MAILTO. Usually, the less info in the mail the better. If you have failures,
247   you can go look at the full log of what happened, generally in
248   $CODEMGR_WS/log/log.<date>/nightly.log (the mail_msg it sent and the proto
249   list are there too). You can also find the individual build logs, like
250   'make clobber' and 'make install' output in $SRC, under names like
251   clobber-${MACH}.out and install-${MACH}.out (for a DEBUG build). These
252   will be smaller than nightly.log, and maybe more searchable.
253
254Files you have to update to add a tool
255--------------------------------------
256
2571.  Add the tool in its appropriate place.
2582.  Update the Makefile as required.
2593.  Update usr/src/pkg/manifests/developer-build-onbld.mf
2604.  Update usr/src/tools/README.tools (this file).
2615.  Repeat 1-4 for any man pages.
