+Shared libraries
+================
+
+Background
+----------
+
+Some packages are providing shared libraries.  When binaries start
+linking to them, the updates to packages with shared libraries must be
+done in a way that doesn't break existing binaries.
+
+Life cycle of a shared library can be summarized in the following way:
+
+1. A SONAME appears
+2. We decide to distribute it
+3. Binaries start linking to it
+4. Time passes, new version of the same library comes along
+5. Binaries stop linking to it
+6. SONAME goes away
+
+Historically, shared libraries were packaged either together with base
+packages, or split off to their own packages.  However, once updated
+shared libraries became available upstream, updated packages included
+both old and new versions of shared libraries.  This required package
+builds to download and compile multiple versions of the same project.
+Notable examples are curl and neon libraries, where CSWcurlrt contained
+all three libcurl.so.2, libcurl.so.3 and libcurl.so.4.
+
+Phasing out of shared libraries was difficult.  To phase out a shared
+library, it is required to verify that no binaries link to it.  All
+dependent packages need to be recompiled against the newest version of
+the library, and once this is done, old versions can be removed.
+However, even when all dependent packages are already recompiled against
+libcurl.so.4, there are no useful indicators that libcurl.so.2 is no
+longer linked to.  To verify this, all dependent packages have to be
+unpacked, and examined using /usr/ccs/bin/dump that the no longer list
+libcurl.so.2 in their NEEDED field.
+
+Once the detection problem is solved, removing the old version of
+a library is not as simple as it could be; The whole CSWcurlrt has to be
+rebuilt and re-released in a new version which no longer includes
+libcurl.so.2.
+
+Goals
+-----
+
+* Simplification of handling of shared library life cycles
+* Allowing to determine whether a specific shared library is no longer
+  linked to, by looking at package dependencies (This avoids potential
+  problem of our keeping "legacy binary libs" in a more modern package
+  for longer than is neccessary. It also avoids having to keep coping
+  the binary into future packages)
+
+Non-goals
+---------
+
+* Providing a reliable mechanism to determine whether a given pkgname
+  contains a shared library
+* Keeping package names short and pretty as a priority
+
+Overview
+--------
+
+As a general rule, each soname shall be packaged in a separate package.
+This way, it's easy to track dependencies on specific sonames, detect
+and phase out sonames that are no longer in use.  It also avoids the
+need to rebuild all the versions of software in question if one of the
+versions needs an update.
+
+This idea is based on the Debian shared libraries packaging policy
+[#debian-policy]_ and has been discussed [#discussion]_ on the mailing
+list.
+
+Advantages:
+
+* easy and complete lifecycle of shared libraries
+
+* phasing out of shared libraries can become part of standard catalog
+  update procedures
+* simpler packages, simpler builds (no need for version modulations and
+  complex merges, good for new maintainers)
+* isolation of old non-fixable files with issues (if there's an old
+  library mentioning /export/medusa, you don't have to worry about it
+  being stopped during release after you push it once)
+* no re-pushing of old files
+* more packages overall (good for stats!)
+* number of packages released per software upgrade remains the same.  If
+  there were, say, 4 packages to release with each Python update, the
+  number remains: 4 per release.  There will be one new CSWlibpython*
+  package, and the old CSWlibpython library won't be upgraded.
+
+
+Disadvantages:
+
+* maintainers need to make more decisions when packaging
+* there's some amount of work to be done to do the transition, such as
+  creation of new packages and dependencies
+* some package names become long and complex (however, they are only
+  dependencies; users don't need to type these in)
+
+Implementation details
+----------------------
+
+Package naming
+~~~~~~~~~~~~~~
+
+Names of packages shall be derived from sonames, and from sonames only.
+They shall not depend on project name, or project version.  If a project
+is named foo, and contains libbar.so.0, the package name shall be based
+on libbar, not foo.

+names. [#soname-pkgname-unit-test]_

+
+Separators
+^^^^^^^^^^
+
+Separators are added between two adjacent numbers, and removed if a number and a letter are next to each other.  For example, ``libfoo.so.0`` becomes ``CSWlibfoo0``, and ``libfoo-1.so.0`` becomes ``CSWlibfoo1-0``.
+
+Linkable shared objects
+~~~~~~~~~~~~~~~~~~~~~~~
+
+The policy or recommendation shall refer to libraries which are //linkable,// meaning other binaries can link against them.  Shared objects in private directories, such as /opt/csw/lib/someproject/foo.so (think Python modules) are not shared libraries which other projects can link to, and therefore there is no benefit in placing them in separate packages.
+
+Special cases
+^^^^^^^^^^^^^
+
+Some packages (e.g. Kerberos libraries) put private shared libraries into /opt/csw/lib.  They don't expose any public API, and only own Kerberos binaries link to them.  Private shared libraries can be bundled with the main package, without splitting them off.

+
+Private shared libraries
+^^^^^^^^^^^^^^^^^^^^^^^^
+
+Some software projects install private (non-linkable) shared libraries
+into libdir (e.g. ``/opt/csw/lib``) by default.  To ensure that they are
+private, they need to be moved to a subdirectory, e.g.
+``/opt/csw/lib/<project>``.
+
+To create a private library and install 32 and 64-bit libraries, they
+need to be laid out as follows:
+
+On sparc::
+
+  /opt/csw/lib/foo
+  /opt/csw/lib/foo/32 --> .
+  /opt/csw/lib/foo/64 --> sparcv9
+
+On i386::
+
+  /opt/csw/lib/foo
+  /opt/csw/lib/foo/32 --> .
+  /opt/csw/lib/foo/64 --> amd64
+
+In GAR, it can be simplified by symlinking:
+
+* 32 to ``$(ISA_DEFAULT)``
+* 64 to ``$(ISA_DEFAULT64)``
+
+The runpath needs to be set to ``/opt/csw/lib/foo/64``, e.g. ``-R/opt/csw/lib/foo/64``.
+
+Grouping shared libraries
+-------------------------
+
+There can be cases in which a set of shared libraries is likely to be
+upgraded together. Considering the following set of libraries:
+
+* libfoo.so.0
+* libfoo_bar.so.0
+* libfoo_baz.so.0
+
+It's possible that all the following libraries will be updated together.
+In such a case, all these shared objects can be put in a single package.
+The decision shall be made by the maintainer.
+
+If versions of shared libraries don't match, chances are that their API
+will not be changing together, and it's a good idea not to package them
+together.  For example, the following three libraries are best kept in
+separate packages.
+
+* libfoo.so.0
+* libfoo_bar.so.1
+* libfoo_baz.so.0
+
+When making the decision, the question a maintainer should ask, should
+be: "Are all these shared libraries going to be retired together?" If
+the answer is positive, shared libraries shall be in a single package.
+However, in the face of uncertainty (it's hard to predict the future),
+placing each file in a separate package is always a safe choice.
+
+Transitioning of the existing packages
+--------------------------------------
+
+Consists of moving the shared library to own package, and making the
+original package an empty, transitional one.  The phasing out of
+transitional packages follows the same rules as any other packages: when
+nothing depends on them, they can be removed.
+
+A simple example:
+
+* Before
+
+  - CSWlibfoo (libfoo.so.1)
+
+* After
+
+  - CSWlibfoo (empty) → CSWlibfoo1 (libfoo.so.1)
+
+For an existing more complex package, with already existing two versions
+of a library:
+
+* Before
+
+  - CSWlibfoo (libfoo.so.1, libfoo.so.2)
+
+* After
+
+  - CSWlibfoo (empty) → CSWlibfoo1 (libfoo.so.1)
+  - CSWlibfoo (empty) → CSWlibfoo2 (libfoo.so.2)
+
+Potential problems
+==================
+
+Potential collisions in package naming would include libfoo.so.1 and
+libfoo-1.so both resolving to CSWlibfoo1.  If this case ever occurs, the
+naming conflict needs to be resolved manually.  However, to this time,
+such a case has been never observed.
+
+Certain sonames are long enough that the corresponding package names are
+over 29 characters long.  However, it affects a small percent of
+libraries, roughly about 98% SONAMEs generate package names within
+limits.
