Import atf 0.19: Changes in version 0.19 *********************** Experimental version released on February 7th, 2014. This is the last release to bundle the code for the deprecated tools. The next release will drop their code and will stop worrying about backwards compatibility between the ATF libraries and what the old tools may or may not support. If you still require the old tools for some reason, grab a copy of the 'tools' directory now. The code in this directory is standalone and does not depend on any internal details of atf-c++ any longer. * Various fixes and improvements to support running as part of the FreeBSD test suite. * Project hosting moved from Google Code (as a subproject of Kyua) to GitHub (as a first-class project). The main reason for the change is the suppression of binary downloads in Google Code on Jan 15th, 2014. See https://github.com/jmmv/atf/ * Removed builtin help from atf-sh(1) and atf-check(1) for simplicity reasons. In other words, their -h option is gone. * Moved the code of the deprecated tools into a 'tools' directory and completely decoupled their code from the internals of atf-c++. The reason for this is to painlessly allow a third-party to maintain a copy of these tools after we delete them because upcoming changes to atf-c++ would break the stale tools. Changes in version 0.18 *********************** Experimental version released on November 16th, 2013. * Issue 45: Added require.memory support in atf-run for FreeBSD. * Fixed an issue with the handling of cin with libc++. * Issue 64: Fixed various mandoc formatting warnings. * NetBSD PR bin/48284: Made atf-check flush its progress message to stdout so that an interrupted test case always shows the last message being executed. * NetBSD PR bin/48285: Fixed atf_check examples in atf-sh-api(3).
