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).

Import atf 0.15: the major goal of this import is to reconcile any local
changes to the atf codebase with upstream code. All local changes should
have been backported, with appropriate portability workarounds where
necessary.

This new release also includes other changes though, such as performance
improvements and bug fixes, and also a major new feature partially
implemented by pgoyette@: the time to execute each test cases and test
program is now recorded and included in the output reports.

The import into NetBSD has been tested natively on amd64 and macppc, and
the full test suite has also been run through anita on amd64 and i386.
No regressions observed... but you never know.

From the NEWS file, the changes in this version are as follows:

Experimental version released on January 16th, 2012.

* Respect stdin in atf-check. The previous release silenced stdin for any
processes spawned by atf, not only test programs, which caused breakage
in tests that pipe data through atf-check.

* Performance improvements to atf-sh.

* Enabled detection of unused parameters and variables in the code and
fixed all warnings.

* Changed the behavior of "developer mode". Compiler warnings are now
enabled unconditionally regardless of whether we are in developer mode or
not; developer mode is now only used to perform strict warning checks and
to enable assertions. Additionally, developer mode is now only
automatically enabled when building from the repository, not for formal
releases.

* Added new Autoconf M4 macros (ATF_ARG_WITH, ATF_CHECK_C and
ATF_CHECK_CXX) to provide a consistent way of defining a --with-arg flag
in configure scripts and detecting the presence of any of the ATF
bindings. Note that ATF_CHECK_SH was already introduced in 0.14, but it
has now been modified to also honor --with-atf if instantiated.

* Added timing support to atf-run / atf-report.

* Added support for a 'require.memory' property, to specify the minimum
amount of physical memory needed by the test case to yield valid results.

* PR bin/45690: Force an ISO-8859-1 encoding in the XML files generated by
atf-report so that invalid data in the output of test cases does not
mangle our report.

branches: 1.1.1.2.6;
Import atf 0.12:

Experimental version released on November 7th, 2010.

* Added the ATF_REQUIRE_THROW_RE to atf-c++, which is the same as
ATF_REQUIRE_THROW but allows checking for the validity of the exception's
error message by means of a regular expression.

* Added the ATF_REQUIRE_MATCH to atf-c++, which allows checking for a
regular expression match in a string.

* Changed the default timeout for test cases from 5 minutes to 30 seconds.
30 seconds is long enough for virtually all tests to complete, and 5
minutes is a way too long pause in a test suite where a single test case
stalls.

* Deprecated the use.fs property. While this seemed like a good idea in
the first place to impose more control on what test cases can do, it
turns out to be bad. First, use.fs=false prevents bogus test cases
from dumping core so after-the-fact debugging is harder. Second,
supporting use.fs adds a lot of unnecessary complexity. atf-run will
now ignore any value provided to use.fs and will allow test cases to
freely access the file system if they wish to.

* Added the atf_tc_get_config_var_as_{bool,long}{,_wd} functions to the atf-c
library. The 'text' module became private in 0.11 but was being used
externally to simplify the parsing of configuration variables.

* Made atf-run recognize the 'unprivileged-user' configuration variable
and automatically drop root privileges when a test case sets
require.user=unprivileged. Note that this is, by no means, done for
security purposes; this is just for user convenience; tests should, in
general, not be blindly run as root in the first place.

Import atf 0.10:

Miscellaneous features

* Added expected failures support to test cases and atf-run. These
include, for example, expected clean exits, expected reception of fatal
signals, expected timeouts and expected errors in condition checks.
These statuses can be used to denote test cases that are known to fail
due to a bug in the code they are testing. atf-report reports these
tests separately but they do not count towards the failed test cases
amount.

* Added the ATF_CHECK_ERRNO and ATF_REQUIRE_ERRNO to the C library to
allow easy checking of call failures that update errno.

* Added the has.cleanup meta-data property to test caes that specifies
whether the test case has a cleanup routine or not; its value is
automatically set. This property is read by atf-run to know if it has to
run the cleanup routine; skipping this run for every test case
significantly speeds up the run time of test suites.

* Reversed the order of the ATF_CHECK_THROW macro in the C++ binding to
take the expected exception as the first argument and the statement to
execute as the second argument.

Changes in atf-check

* Changed atf-check to support negating the status and output checks by
prefixing them with not- and added support to specify multiple checkers
for stdout and stderr, not only one.

* Added the match output checker to atf-check to look for regular
expressions in the stdout and stderr of commands.

* Modified the exit checks in atf-check to support checking for the
reception of signals.

Code simplifications and cleanups

* Removed usage messages from test programs to simplify the
implementation of every binding by a significant amount. They just now
refer the user to the appropriate manual page and do not attempt to wrap
lines on terminal boundaries. Test programs are not supposed to be run
by users directly so this minor interface regression is not important.

* Removed the atf-format internal utility, which is unused after the
change documented above.

* Removed the atf-cleanup internal utility. It has been unused since the
test case isolation was moved to atf-run in 0.8

* Splitted the Makefile.am into smaller files for easier maintenance and
dropped the use of M4. Only affects users building from the repository
sources.

* Intermixed tests with the source files in the source tree to provide
them more visibility and easier access. The tests directory is gone from
the source tree and tests are now suffixed by _test, not prefixed by t_.

* Simplifications to the atf-c library: removed the io, tcr and ui
modules as they had become unnecessary after all simplifications
introduced since the 0.8 release.

* Removed the application/X-atf-tcr format introduced in 0.8 release.
Tests now print a much simplified format that is easy to parse and nicer
to read by end users. As a side effect, the default for test cases is
now to print their results to stdout unless otherwise stated by providing
the -r flag.

* Removed XML distribution documents and replaced them with plain-text
documents. They provided little value and introduced a lot of complexity
to the build system.

* Simplified the output of atf-version by not attempting to print a
revision number when building form a distfile. Makes the build system
easier to maintain.
