[ANNOUNCEMENT] Updated: cygport-0.11.0-1

[ANNOUNCEMENT] Updated: cygport-0.11.0-1

[Yaakov (Cygwin/X)]

I have just released cygport-0.11.0 for the Cygwin distribution and the 
Fedora Cygwin repository.  New features in this release:

* Vastly improved dependency detection (works only on Cygwin):
- commands called by unindented fully-qualified path in 
postinstall/preremove scripts
- script interpreters called via shebang
- DLLs corresponding to import libraries
- Link libraries listed in .la libtool libraries
- Link libraries listed in pkg-config Libs: and Libs.private: fields
- Other pkg-config modules listed in pkg-config Requires: and 
Requires.private: fields
- GObject Introspection module and DLL dependencies
- Java jar dependencies (via java-jdepend)
- OCaml dependencies on other OCaml libraries (via ocaml-findlib) and 
native-code link libraries required by .cmxa files
- Perl, PHP, PyPy, Python, Ruby, and Tcl module dependencies
- Third-party Vala API module dependencies

* Automatic setup.hint generation.  This allows a .cygport file to be a 
completely self-contained, single-file packaging solution.  The 
[PKG_]CATEGORY (for category:), [PKG_]SUMMARY (for sdesc:), and 
[PKG_]DESCRIPTION (for ldesc:) variables (as documented in the manual) 
must be defined in order to activate this feature.  The requires: line 
is written automatically (but may be added to via [PKG_]REQUIRES) and 
displayed at the end of the packaging stage for verification; 
inter-subpackage dependencies are also detected.  Handwritten setup.hint 
files still work as before, and override automatic generation.

* New cygclasses: pypy, pypy-distutils, rubygem, sugar.

* .gem files are unpacked with gem(1) (integrated in ruby-1.9.x) and the 
.gemspec file is recreated in order to be patchable.  Sugar Activity 
bundles (.xo) are now supported.

When doing the packaging step with your latest cygport release on gnutls I get the following:
    
which: no KERNEL32.dll in (/misc/src/release/gnutls-2.12.20-1/inst/usr/bin:/usr/local/bin:/usr/bin:/usr/local/scripts:/usr/local/sbin:/usr/sbin:/usr/lib/lapack)
>>> gnutls requires: libgnutls26 libreadline7
which: no KERNEL32.dll in (/misc/src/release/gnutls-2.12.20-1/inst/usr/bin:/usr/local/bin:/usr/bin:/usr/local/scripts:/usr/local/sbin:/usr/sbin:/usr/lib/lapack)
>>> libgnutls26 requires: libgcc1 libgcrypt11 libintl8 liblzo2_2 libp11-kit0 libstdc++6 libtasn1_3 zlib0
>>> gnutls-devel requires: gettext libgcrypt-devel libgnutls26 libiconv liblzo2-devel libp11-kit-devel libtasn1-devel
>>> gnutls-doc requires:


When I call cygcheck directly on cyggnutls-26.dll I get the following:

10:31 PM [515]> cygcheck ./*.dll
G:\misc\src\release\gnutls-2.12.20-1\inst\usr\bin\cyggnutls-26.dll
  G:\bin\cygwin1.dll
    C:\WINDOWS\system32\KERNEL32.dll
      C:\WINDOWS\system32\ntdll.dll
  G:\bin\cyggcrypt-11.dll
    G:\bin\cyggcc_s-1.dll                               <-------------------- libgcc1
    G:\bin\cyggpg-error-0.dll
      G:\bin\cygintl-8.dll                              <-------------------- libintl8
        G:\bin\cygiconv-2.dll
    C:\WINDOWS\system32\ADVAPI32.DLL
      C:\WINDOWS\system32\RPCRT4.dll
        C:\WINDOWS\system32\Secur32.dll
    C:\WINDOWS\system32\USER32.dll
      C:\WINDOWS\system32\GDI32.dll
  G:\bin\cygp11-kit-0.dll
  G:\bin\cygtasn1-3.dll
  G:\bin\cygz.dll


So in the above requires line for libgnutls26, libggc1 and libintl8
shouldn't be included at all because libgcrypt11 already depends on
them. I'm I wrong here ? And what about the "which: no KERNEL32.dll"
stuff above ? Can it be suppressed without adding C:\WINDOWS\system32\
to the PATH ?

cygport uses objdump to find binary dependencies, which unlike cygcheck,
lists direct dependencies only and doesn't worry about subdependencies:

$ objdump -p /usr/bin/cyggnutls-26.dll | grep "DLL Name"
	DLL Name: cygwin1.dll
	DLL Name: cyggcrypt-11.dll
	DLL Name: cygintl-8.dll
	DLL Name: cygtasn1-3.dll
	DLL Name: cygz.dll
	DLL Name: KERNEL32.dll

So libgnutls26 has a hard direct dependency on libintl8.  To understand
why this is done, let's say that a future release of gettext changes the
ABI version again, and then soon thereafter libgcrypt was rebuilt
against that new libintlX.  libgnutls26 would *still* require libintl8,
and can't rely on libgcrypt11 to provide that dep.

OTOH, note that libiconv2 is *not* listed as a dep, even though libintl8
depends on it.  That's because if in the future libiconv would get an
ABI version bump and the same gettext were rebuilt against that, even
though libintl8 would now depend on libiconvX, libgnutls would NOT need
to be rebuilt, and libiconv2 would no longer be necessary.

So for these purposes, objdump is a more precise means of dependency
detection than cygcheck.

Fixed in git master, commit a268dc3.
