We have prepared the new chain of updates for the LSB Database and

The sources are in Bazaar (unofficial/ispras-dbadmin and
unofficial/ispras-lsb-specdb modules; init files for community tables are in
/srv/www/bzr/unofficial/ispras-lsb/community_init at spidey). Below is the
list of changes (see also
http://ispras.linux-foundation.org/index.php/DB_Navigator_Releases and


LSB Navigator 1.9

New Features

1.       New subsection in the 'Linux Applications Analysis Center' -
'Interpreters Usage Frequency'. 

2.       Comments for non-LSB libraries used by applications are now showed
on the basis of the LibraryAttribute table. 

3.       More consistency checks - excluded types used as parameters and
return types of included interfaces. 

4.       Tests and Coverage pages speed up (about 2 times faster now). 

5.       Interface search speed up (about 2 times faster now). 

6.       Support for several versions of one included symbol on the same

7.       The concept of manually maintained 'List of Approved Libraries' is
introduced, for which we guarantee presence status in distributions (i.e.
explicitly search for each library from the list while analyzing

8.       New section in the admin mode - 'Approved Libraries Presence in

9.       Notes about data completeness on libraries and interfaces home
pages (on the basis of the new ApprovedLibrary table). 

10.   Architecture filter is now disabled on those pages where it doesn't
make any sense.

11.   'Class Usage by Applications' statistics is displayed on the class
homepage (with possibility of obtaining list of such applications as well as
lists of particular symbols used by every app). 

12.   Added search for headers.  

Bug Fixes

1.       In the Interface search results sometimes less than 500 entries
were displayed while actually there are more than 500 corresponding records
in the db. 

2.       If interpreted language module in a distribution is provided by
several components, then only one component was displayed. 

3.       When requesting applications using the symbol on the 'excluded
interfaces usage' page (clicking on 'list...'), incorrect data was sometimes
displayed for symbols provided by more than one library.


LSB Database & Scripts 1.4

Changes in Database Schema

1.       New tables in the community part - ApprovedLibrary, AppInterpreter
and DistrVendor. 

2.       ArchInt.AIdeprecated field is introduced, Interface.Ideprecated
field is dropped. This allows deprecating certain versions of symbols. 

3.       Size of all 'appearedin', 'withdrawnin', 'mandatorysince' and
'deprecatedsince' fields is reduced to 5.

4.       New cache table (cache_RIntCaseInsensitiveNames) with case
insensitive interface names for Navigator search speed up. 

5.       The release incorporates the following changes already released as
patches through bugzilla:

a.       Drop Csrconly field (
<http://bugs.linuxbase.org/show_bug.cgi?id=2039> bug 2039). 

b.       Separate Ctype value for accessors (
<http://bugs.linuxbase.org/show_bug.cgi?id=2070> bug 2070).

 Data Changes

1.       For those LSB functions whose version is shifted due to long double
support changes (see  <http://bugs.linuxbase.org/show_bug.cgi?id=2177> bug
2177) necessary data is added to the ArchInt table. 

2.       Added data for 7 distributions and 77 applications. 

3.       Pure python/perl applications are now assigned to the 'Generic'

4.       Some empty 'Ilibrary' fields in the Interface are now filled with
appropriate data.

5.       The release incorporates the following changes already released as
patches through Bugzilla: 

a.       libc uplift and analysis of excluded symbols used by applications
(~50 task entries in Bugzilla). 

b.       libstdc++ uplift (bug 1962
<http://bugs.linuxbase.org/show_bug.cgi?id=1962> ). 

c.       GTK+ stack uplift (bug 2095
<http://bugs.linuxbase.org/show_bug.cgi?id=2095> ). 

d.       Added libXtst information (bug 2020
<http://bugs.linuxbase.org/show_bug.cgi?id=2095> ).

e.       Fixes for GL and some X11 headers (bug 706
<http://bugs.linuxbase.org/show_bug.cgi?id=706> ). 

f.         Fixes for 'overspecified' pthreads (bug 1926
<http://bugs.linuxbase.org/show_bug.cgi?id=1926> ). 

g.       Add missing png.h structures (bug 1966
<http://bugs.linuxbase.org/show_bug.cgi?id=1966> ). 

h.       Add missing glu.h declarations (bug 2027
<http://bugs.linuxbase.org/show_bug.cgi?id=2027> ).

Scripts Changes

1.       'gensrc' target in the build_env/stub_libs makefile now produces
libraries for all LSB versions at the same time. Instead of 7 folders (one
per architecture) we now have a folder for every LSB version starting with
3.0 with seven subfolders corresponding to different architectures. 

2.       packaging scripts are modified according to the stub_libs structure
changes. LSB SDK now contains a separate library directory for every LSB
version starting with 3.0. Directories are named 'lib-3.0', 'lib-3.1', etc.
(for 64bit architectures, 'lib64' prefix is used). /opt/lsb/lib is still
exists as a symlink to a directory corresponding to the highest LSB version.

3.       lsbcc now uses directory corresponding to the target LSB version.
If no version is specified, '/opt/lsb/lib/' will be used. 

4.       mkstublibs can now handle several versions of one symbol in the
same library. Not-deprecated version will be marked as default in this case.
There should be no several not-deprecated versions. 

5.       mkstublibs now automatically calculates size for _ZTSN* ('typeinfo
name for ...') symbols, appropriate records are dropped from the
'missing_data' files.

6.       Corrections to mkheader to deal with types having FuncPtr as a base

7.       The release incorporates the following changes already released as
patches through Bugzilla: 

a.       Remove needs for hand-edited devchk tests for 3 headers (bug 1519
<http://bugs.linuxbase.org/show_bug.cgi?id=1519> ). 

b.       Generators speed up (bug 2049 - libchk
<http://bugs.linuxbase.org/show_bug.cgi?id=2049> , bug 2035 - mkstublibs
<http://bugs.linuxbase.org/show_bug.cgi?id=1519> ). 

c.       build_env/headers/makefile modification to generate .defs in
different directories for for different LSB versions (bug 2041
<http://bugs.linuxbase.org/show_bug.cgi?id=2041> ). 

d.       devchk modification to omit type's reserved members checks (bug
1494 <http://bugs.linuxbase.org/show_bug.cgi?id=1494> ). 

e.       Added 'optimize' rule for specdb 'make restore' for general speedup
(bug 2062 <http://bugs.linuxbase.org/show_bug.cgi?id=2062> ).


Please note that the recent changes in the DB & scripts finish the
multi-LSB-version lsbcc subproject.


The new versions will show up at http://linuxfoundation.org/navigator/ soon
(after Mats transfers the new releases to the LF server). Until that the
working demo can be seen at
