r552: * The "reverse hangover" release.
* dh_strip: better documentation, removed extraneous "item" from SYNOPSIS. Closes: #162493 * dh_strip: detect and don't strip debug/*.so files. * Note that 4.1.11 changelog entry was incorrect, dh_perl worked fine without that change, but the new behavior is less likely to break things if dpkg-gencontrol changes. * Various improvements to debhelper(1).

@@ -20,8 +20,17 @@ dh_strip is a debhelper program that is responsible for stripping
executables, shared libraries, and static libraries that are not used for
debugging.
-It assumes that files that have names like lib*_g.a are static libraries
-used in debugging, and will not strip them.
+This program examines your package build directories and works out what
+to strip on its own. It uses L<file(1)> and file permisions and filenames
+to figure out what files are shared libraries (*.so), executable binaries,
+and static (lib*.a) and debugging libraries (lib*_g.a, debug/*.so), and
+strips each as much as is possible. (Which is not at all for debugging
+libraries.) In general it seems to make very good guesses, and will do the
+right thing in almost all cases.
+
+Since it is very hard to automatically guess if a file is a
+module, and hard to determine how to strip a module, dh_strip does not
+currently deal with stripping binary modules such as .o files.

This needs more thought.
-* Support use of environment variables in data taken from user, ie, in
- debian/dirs. The problem with doing this is that we really want to allow
- any filenames in that input, even those that look like environment
- variables. However, it may be worth adding a switch to make it parse
- environment variables. (#20964)
-* It's possible to speed up debhelper by having it cache some values that
- multiple commands call. One way to do this would be to write dh_cache,
- that generates the cache. The catch is that if the user runs that program,
- they are stating that they don't do anything later to invalidate the cache,
- without calling dh_cache again. (#23792)
-* Add a switch to dh_installdeb to allow it to do user defined
- substitutions. OTOH, maybe it's better if people just sed
- postinst.in before debhelper gets its hands on it... (#25235)
* install-info, as of dpkg 1.10, parses the info file for section if
--section is not given. So I should be able to stop parsing it myself for
section, after dpkg 1.10 has been around long enough.
