[csw-maintainers] Checkpkg database update and new checkpkg tests

[Yann Rouillard]

Hi everyone,

We had to fix some issues in the last commit, nothing really impacting but
for safety reasons, we updated again the schema version to be sure nothing
would be uploaded again using the previous code.

So don't forget do update again your code base.

Thanks again to Maciej for its time and help on this issue.

Bye.

Yann

>> take into account the LD_OPTIONS default variable defined by GAR.
>> In that case, you will probably have one the two new checkpkg errors
>> documented here:
>> http://wiki.opencsw.org/checkpkg-error-tags#no-direct-binding
>> http://wiki.opencsw.org/checkpkg-error-tags#soname-unused
>>
>> An important note: ldd is used to gather some information about binaries.
>> As ldd only work on binaries of the same architecture, this means that the
>> package content analysis step can now only be done on a server with the
>> same architecture as the package checked.
>> The real check step however can still be performed from anywhere.
>>
>>
>> These new checks required to add new information about symbols and
>> linkage in the checkpkg database. This information can now easily be used
>> to create others checks related to linkage, symbol and interfaces.
>> For exemple I also added a new test to detect if a binary is using a
>> forbidden version interface:
>> http://wiki.opencsw.org/checkpkg-error-tags#forbidden-version-interface-dependencies
>>
>> Unfortunately this also requires to re-import all the existing packages

>> previous packages.
>> I will begin this operation starting from now, it takes around 18h and
>> can be done live without preventing maintainers to upload new packages.
>> However, at the end, I will update the db schema version and commit the
>> new code. After this, you will have to svn update your gar build system or
>> it will complains about db schema version difference.
>> The procedure followed is described on the wiki:
>> http://wiki.opencsw.org/checkpkg#toc<http://wiki.opencsw.org/checkpkg#toc8>
>>
>>  I'll keep you updated as soon as it is finished.
>>
>> If you have any question, don't hesitate.

>> BTW, happy New Year to everybody !
