26Introduction
27------------
28
29This README describes some basics about creating, modifying, and
30building packages in ON.  All package creation in ON is done using
31tools available to our customers.  If terminology in this document
32is confusing, you may wish to review the pkg(7) manpage.
33
34Packaging Overview
35------------------
36
37usr/src/pkg/ contains the definitions and rules needed to build an IPS
38repository which contain the deliverables from an ON build.
39
40The manifests directory contains all manifests, and has one file
41per package.  For most packaging changes you only need to add or
42change the packaging manifests themselves.
43
44The build rules create a package repository.  Separate DEBUG and
45non-DEBUG versions are built, and are available at:
46    $CODEMGR_WS/packages/$MACH/nightly[-nd]/repo.redist
47
48Building Packages
49-----------------
50
51The -p option to nightly will build the IPS repository.
52
53Alternatively, in usr/src/pkg/Makefile there are make targets for:
54
55	all
56	    Process manifests into their final form with unresolved
57	    dependencies before publication.
58
59	install
60	    Publish packages.
61
62	gendeps
63	    Run `pkgdepend resolve`.  See Dependencies section.
64
65	protocmp
66	    Compare the proto area against package definitions for
67	    missing or incorrect files.
68
69	pmodes
70	    Check file and directory modes for best practices.
71
72	check
73	    Run protocmp and pmodes.
74
75The build behavior may modified by the following variables:
76
77	SUPPRESSPKGDEP
78	    If SUPPRESSPKGDEP is set to "true" in your environment,
79	    package dependencies will not be generated.  This variable
80	    should not be set in normal builds as it will mask product
81	    bugs.
82
83	PKGDEBUG
84	    If PKGDEBUG is set in your environment, $MAKE will print
85	    detailed information about the commands it executes to
86	    process and publish packages.
87
88A set of intermediate build products are placed in
89usr/src/pkg/packages.$MACH/.  These can be useful during development.
90
91	.mog
92	    The resulting package manifest after running pkgmogrify(1)
93	    on the supplied manifest.  See below for details on
94	    pkgmogrify(1) use in ON.
95
96	.dep
97	    The resulting manifest after running `pkgdepend generate`
98	    on the .mog manifest.
99
100	.res
101	    The resulting manifest after running `pkgdepend resolve`
102	    on the .dep manifest.
103
104Incremental Builds
105------------------
106
107   If you want to process a subset of manifests, simply set PKGS on the
108   make command line and specify the "all" target.  If you want to process
109   them all, simply specify the "all" target.
110
111	% dmake -e PKGS="BRCMbnx BRCMbnxe" all
112	% dmake -e all
113
114   If you want to publish a subset of packages, simply set PKGS on the
115   make command line and specify the "install" target.  Overriding PKGS
116   will cause dependency resolution to be limited to PKGS from the
117   current build, with a fallback to packages installed on the build
118   system.  If you want to publish them all, simply specify the
119   "install" target.
120
121	% dmake -e PKGS="BRCMbnx BRCMbnxe" install
122	% dmake -e install
123
124   You can also use package names, or package names with ".pub"
125   extensions, as build targets.  This will cause processing or
126   publication of the specified package(s).
127
128   The on-disk repository will be initialized when it does not exist,
129   or when you run nightly -p.  If you build incrementally,
130   packages will simply be added to the existing repository.
131
132   To do cross-platform packaging, prefix your target with (for
133   example) "i386/", as in "dmake i386/install".  Note that we
134   currently pull some license files directly from a built source
135   tree, so if you do this in a workspace that had proto area copied
136   in via nightly -U, then you'll need to set $SRC to point to the
137   workspace that was actually built.
138
139Testing Packages
140----------------
141
142To test the generated repository, you should use the "onu" tool
143available from /opt/onbld/bin or usr/src/tools/scripts/ to setup and
144upgrade your system.  A manpage is available in /opt/onbld/man
145or usr/src/tools/scripts/onu.1.
146
147Alternatively, you can manually start a pkg.depot(8) server to
148serve the generated repository to multiple test machines.
149
150	Start up a depot on your build machine.
151	    cd $CODEMGR_WS/packages/$MACH/nightly[-nd]
152	    /usr/lib/pkg.depotd -d repo.redist -p <port> &
153
154	    Make SURE you choose an unused port and the depot
155	    starts successfully.
156
157	    The depot can be started across NFS as well if you
158	    have a fast pipe.
159
160	Configure your test system.
161	    pkg set-publisher -P -g http://<your server host>:<port> on-nightly
162	    pkg set-publisher --non-sticky opensolaris.org
163	    pkg uninstall entire
164
165	pkg image-update your test system.
166	    pkg image-update will upgrade all packages on your test system
167
168Always make sure your bits are installed with image-update.
169	Check your versions.
170	    pkg info osnet-incorporation
171
172	Multiple packages should be updated.
173	    If you did a full build, all ON packages will be updated.
174	    When image-update tells you that only one or two packages has
175	    been updated, you likely did not get the updates you expected.
176
177There are various tactics for troubleshooting a failed upgrade.
178	Make sure entire is uninstalled.
179
180	pkg install -nv osnet-incorporation@<your version>
181	    Ask IPS to explicitly check if ON can be installed, and
182	    if it can't, tell you why not.
183
184	Obsolete and renamed packages can cause trouble.
185	    pkg search -l ::pkg.renamed:true
186	    pkg search -l ::pkg.obsolete:true
187
188
189Making Packaging Changes
190------------------------
191
192Package definitions are in usr/src/pkg/manifests/, and have one
193file per package, including for multi-architecture packages.  For
194most packaging changes you only need to add or change the packaging
195manifests themselves.  No packaging metadata may be kept outside of the
196manifests. If you find yourself needing to modify usr/src/pkg/Makefile,
197you're almost certainly doing something wrong.
198
199Remember that the "check" target is available to check many of
200your packaging changes.
201
202We run pkgmogrify(1) over the manifests before publication.  This
203allows us to apply a set of macros and package transformations in
204order to make the manifests themselves easier to maintain.
205
206We supply a set of commonly-used macros for use in package manifests.
207These are the PKGMOG_DEFINES in usr/src/pkg/Makefile.
208
209	$(i386_ONLY)
210	$(ARCH)
211	$(ARCH32)
212	$(ARCH64)
213	$(PKGVERS), which is set to
214	   $(PKGVERS_COMPONENT),$(PKGVERS_BUILTON)-$(PKGVERS_BRANCH)
215
216pkgmogrify(1) also allows us to include a set of default transformations.
217The definitions for these transforms are in usr/src/pkg/transforms/.  An
218overview of their use is supplied here, but for a full accounting, please
219read pkmogrify(1) and the files themselves.
220
221	defaults
222	    This transform is applied to all manifests.  It specifies
223	    a set of sensible default permissions, a set of
224	    directory locations for which the reboot-needed actuator
225	    is always applied to files, and some other basic defaults.
226
227	publish
228	    This transform is applied to all manifests.  It ensures
229	    that manifest lines which don't apply to the current
230	    architecture are stripped.
231
232	restart_fmri
233	    This transform is applied to all manifests.  It modifies
234	    all package manifest lines for SMF manifests in standard
235	    locations to include an actuator which runs manifest-import
236	    on installation/update/removal, as well as some others.  If
237	    you're adding a new class of file that would benefit from
238	    a restart or refresh of a specific SMF service, please add
239	    it here.
240
241	extract_metadata
242	    This transform is applied to all manifests.  It deals with
243	    manipulations required for packaging metadata like
244	    pkg.renamed, and pkg.obsolete.
245
246	hollow_zone_pkg
247	    This transform is available for explicit inclusion in
248	    some manifests.  It ensures that all contents of the
249	    package are not installed within a non-global zone, but the
250	    package and its metadata are available in order to satisfy
251	    packaging dependencies.
252
253pkgmogrify(1) also allows us to use comments and continuation lines
254in our manifests.
255
256Zones and Packages
257------------------
258
259pkg(7) uses variants to implement zones.  If a package is marked
260with both global and non-global zone variants, the package contents will
261be installed in both global and non-global by default.
262	set name=variant.opensolaris.zone value=global value=nonglobal
263
264Specific actions within a package can be tagged as applying to only
265the global zone or only the non-global zones.
266
267The hollow_zone_pkg transform described above is also available to
268simplify a common packaging scenario.
269
270Dependencies
271------------
272
273Package dependencies are automatically calculated during build time
274using pkgdepend(1).  After you've done a build, you can verify your
275dependencies in the <package>.res file described above.  If the
276file is missing a dependency that you believe could be auto-detected,
277please file a bug against pkgdepend(1).
278
279Dependencies can be added manually using the "depend" action.  Please
280add a comment describing why the dependency is required.
281
282Moving Content Between Packages and Removing Content
283----------------------------------------------------
284
285pkg(7) tracks when content is removed from packages, and automatically
286removes it.
287
288If you need to move content between packages, there are two primary
289things to do.
290
291	"preserve" files must be marked with original_name.
292	    The first time a "preserve" file moves between packages,
293	    you must set original_name=<original package>:<file>
294	    in that file's action.  Subsequent moves do not require
295	    modification.
296
297	Consider adding a dependency on the new package.
298	    The only way a system will end up with a new package
299	    after upgrade is if an existing package depends on it.
300
301Renaming a Package
302------------------
303
304To rename a package, leave the old package manifest in place, but
305empty it of all delivered content.  The old package should include:
306
307	set name=pkg.fmri with the version set explicitly to the
308	    build you're integrating into.  For example, if you wanted
309	    to rename SUNWrmodu in build 133 you'd change the pkg.fmri
310	    line to read
311	    set name=pkg.fmri value=pkg:/SUNWrmodu@0.5.11,5.11-0.133
312
313	set name=pkg.renamed value=true
314
315	The architectures and variants you're renaming.  These
316	    should just be copied from your old package, as you
317	    must rename a package on all architectures and
318	    variants simultaneously.
319
320	A dependency on the new package.
321
322If there were "preserve" files in the package you're renaming, make
323sure to create original_name settings in the new package.
324
325If there was a org.opensolaris.noincorp property in the package being
326renamed, make sure you keep it in both the original and the renamed
327packages.
328
329EOFs and Removals
330-----------------
331
332To remove files, directories, drivers, or anything else within a package,
333simply stop delivering them in the package.  IPS will manage the removal
334of no longer delivered content.
335
336Package removals have impact on the rest of the system.  Before marking
337a package as obsolete, search in the OpenSolaris development
338repository (http://pkg.opensolaris.org/dev or http://ipkg.sfbay/dev)
339to find out if any other packages depend on the software you intend
340to EOF.  If any packages do, you need to coordinate with those
341consolidations.
342
343The "slim_install" package may depend on ON packages.  If it does,
344you must send a FLAG DAY message for ON users and PIT who test
345install.  You must also file an installation bug to get that package
346updated in the same build or earlier than you intend to integrate.
347You should also test install yourself.  You can do this by replacing
348the "slim_install" in your Distro Constructor manifest with the
349explicit list of packages to install.
350
351To remove a package, you must mark it as obsolete.  You must *also* mark
352as obsolete any packages which are renamed ancestors of this package, and
353remove their rename dependencies.  Here is what you must do.
354
355To find rename ancestors, select all of the manifests which are renames,
356then look for the one which was renamed to the package you care about.
357For example, to find rename ancestors of 'system/zones', do the following:
358
359    $ cd usr/src/pkg/manifests
360    $ mypkgname=system/zones
361    $ grep -l "fmri=pkg:/$mypkgname@" `grep -l pkg.renamed *.p5m` /dev/null
362    SUNWzone.p5m
363
364Make sure to check that the package has not undergone multiple renames!
365
366    $ mypkgname=SUNWzone
367    $ grep -l "fmri=pkg:/$mypkgname@" `grep -l pkg.renamed *.p5m` /dev/null
368    $
369
370Once you have the renamed ancestor list, for *each* of the packages (the
371newly obsolete package, and its renamed ancestors), edit the package as
372follows:
373
374	Update 'set name=pkg.fmri' with the version set explicitly to the
375	    build you're integrating into.  For example, if you wanted
376	    to remove SUNWwbsd in build 133 you'd change the pkg.fmri
377	    line to read:
378	    'set name=pkg.fmri value=pkg:/SUNWwbsd@0.5.11,5.11-0.133'
379
380	Add 'set name=pkg.obsolete value=true'.
381
382	Maintain the architecture and variant declarations in the
383	    package you are obsoleting.  Note that you must obsolete a
384	    package on all architectures and variants simultaneously.
385
386	Delete everything else.
387
388	If the package is a renamed ancestor, leave a comment behind as
389        follows:
390
391	   # Was renamed to <other-pkg-name>, both now obsolete.
392
393Here is a complete example.  SUNWfoobar was a package which was renamed
394to system/foobar in build 140, and then later obsoleted in build 150.
395Note that in all cases the package FMRI is updated to the obsoletion
396build, 150.
397
398    SUNWfoobar.p5m:
399        # Was renamed to system/foobar, both now obsolete.
400        set name=pkg.fmri value=pkg:/SUNWfoobar@0.5.11,5.11-0.150
401        set name=pkg.obsolete value=true
402        set name=variant.arch value=$(ARCH)
403
404    system-foobar.p5m:
405	set name=pkg.fmri value=pkg:/system/foobar@0.5.11,5.11-0.150
406	set name=pkg.obsolete value=true
407	set name=variant.arch value=$(ARCH)
408
409Creating a Package
410------------------
411
412The easiest thing is to copy a package similar to the one you're
413trying to create.  Note that packages are no longer split on the
414/usr and / boundary.
415
416The following actions are required for all packages in ON.
417	set name=pkg.fmri
418	    Every package must have an FMRI.  That is the package's
419	    name.
420
421	set name=pkg.summary
422	    Every package must have a short summary of its purpose.
423
424	set name=pkg.description
425	    Every package must have a one-sentence description of
426	    its purpose.
427
428	set name=variant.arch
429	    Every package must specify which architectures it delivers.
430
431	set name=info.classification
432	    Every package must specify a category for the packaging GUI.
433	    You must use an existing category, and may not invent new ones.
434	    Existing categories and their subcategories are listed
435	    in /usr/share/package-manager/data/opensolaris.org.sections.
436
437	license
438	    All packages must specify a set of license actions.
439
440You don't need to set the following.  They're taken care of for all OS/Net
441packages in the transforms/common_actions file.
442
443	set name=variant.opensolaris.zone
444	    Every package must specify whether it can be installed in
445	    global zones, non-global zones, or both.  All ON packages are
446	    delivered in both global and non-global zones.
447
448	set name=org.opensolaris.consolidation value=osnet
449	    All packages from OS/Net come from OS/Net...
450
451Drivers and Packages
452--------------------
453
454Scripting is no longer required to deal with addition or removal of
455drivers in ON.  A "driver" action should be specified for each driver,
456and IPS will handle updates to all the driver files.
457
