Hi developers!
I just have implemented compile time type check in package callbacks (see
fate#302296 or bnc#51913). In short: function references are now used instead of
strings (e.g. Pkg::CallbackProgressDownload(PackageCallbacks::ProgressDownload)
instead of Pkg::CallbackProgressDownload("PackageCallbacks::ProgressDownload")
which was error prone).
The advantage is that registering an invalid function is found at compile time
now. Thanks to this feature I have found some problems and fixed them (missing
callback functions, wrong parameters etc...)
The disadvantage is that the binary compatibility of *.ybc files is broken now.
Use 'y2tool y2compile' from yast2-devtools to recompile the modules after
installing new yast2-pkg-bindings, yast2-packager and yast2.
The implementation of the package callbacks has been moved to yast2.rpm to break
cyclic dependency between yast2 and yast2-packager. Another change is that
PackageCallbacksInit.ycp module is obsoleted now, but remains for backward
compatibility. Use PackageCallbacks::InitPackageCallbacks() instead of
PackageCallbacksInit::InitPackageCallbacks() in your modules.
I have also adapted the other yast packages which register their own callbacks
(autoinstallation, online-update, product-creator), please check my changes and
submit the new package.
The change was quite large (and spread across 6 packages), if you find any
problem with the new callbacks then contact me.
