Alex Richardson c203bd70b5 Import atf 0.22 snapshot ca73d08c3fc1ecffc1f1c97458c31ab82c12bb01 
This includes improvements to the atf-sh helper functions that
significantly reduce the number of spawned processes for each test
and therefore speeds up running the testsuite noticeably.

Major changes between releases Automated Testing Framework
===========================================================================
Changes in version 0.22
***********************
STILL UNDER DEVELOPMENT; NOT RELEASED YET.
DON'T FORGET TO BUMP THE -version-info PRE-RELEASE IF NECESSARY!
* Issue #23: Fix double-free triggered by atf_map_insert in low memory
scenarios, caused by an overlook in the atf_list code.
* Issue #29: Fixed various typos and formatting errors in manual pages.
* Issue #31: Added require.progs metadata properties to the tests that
need a compiler to run.
* Added the atf_check_not_equal function to atf-sh to check for
unequal values.
Changes in version 0.21
***********************
Released on October 23rd, 2014.
* Restored the atf(7) manual page to serve as a reference to all the other
manual pages shipped by ATF.
* Added the -s flag to atf-sh to support specifying the shell interpreter
to be used.
* Removed ATF_WORKDIR. The only remaining consumers have been converted to
use the standard TMPDIR environment variable. As a benefit, and because
Kyua forces the TMPDIR to live within the test case's work directory,
any stale files left behind by ATF will be automatically cleaned up.
* Documented the environment variables recognized by each component in the
relevant manual pages. This information was lost with the atf-config(1)
removal.
* Added a new "require.diskspace" metadata property to test cases so that
they can specify the minimum amount of disk space required for the test
to run.
* Renamed the atf-{c,c++,sh}-api(3) manual pages to atf-{c,c++,sh}(3) for
discoverability purposes. Symbolic links are provided for the time
being to still make the old names visible.
* Issue #5: Recommend the (expected, actual) idiom for calls to the test
macros in the manual pages.
* Issue #7: Stopped catching unhandled exceptions in atf-c++ tests. This
propagates the crash to the caller, which in turn allows it to obtain
proper debugging information. In particular, Kyua should now be able to
extract a stacktrace pinpointing the problem.
* Issue #8: Fixed atf-c/macros_test:use test failures spotted by the clang
that ships with FreeBSD 11.0-CURRENT.
* Issue #12: Improved documentation of atf-sh(3) and atf-check(1) by better
explaining how they relate to each other.
* Issue #14: Stopped setting 'set -e' in atf-sh. This setting was
initially added as a way to enable a "strict" mode in the library and to
make test cases fail fast when they run unprotected commands. However,
doing so in the library is surprising as the responsibility of enabling
'set -e' should be on the user's code. Also, 'set -e' introduces
inconsistent behavior on subshells and users do not expect that.
* Issue #15: Fixed atf_utils_{fork,wait} to support nested calls.
* Issue #16: Fixed test failures (by removing a long-standing hack) on
systems that lack \e support in printf(1).
* Issue #19: Removed stale references to atf-config and atf-run.
Changes in version 0.20
***********************
Experimental version released on February 7th, 2014.
This is the first release without the code for the deprecated tools. If
you require such code, please fetch a copy of the 0.19 release and extract
the 'tools' directory for your own consumption.
* Removed the deprecated tools. This includes atf-config, atf-report,
atf-run and atf-version.
* Issue #8: Fixed atf-c/macros_test:use test failures spotted by the clang
that ships with FreeBSD 11.0-CURRENT.
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).
Changes in version 0.17
***********************
Experimental version released on February 14th, 2013.
* Added the atf_utils_cat_file, atf_utils_compare_file,
atf_utils_copy_file, atf_utils_create_file, atf_utils_file_exists,
atf_utils_fork, atf_utils_grep_file, atf_utils_grep_string,
atf_utils_readline, atf_utils_redirect and atf_utils_wait utility
functions to atf-c-api. Documented the already-public
atf_utils_free_charpp function.
* Added the cat_file, compare_file, copy_file, create_file, file_exists,
fork, grep_collection, grep_file, grep_string, redirect and wait
functions to the atf::utils namespace of atf-c++-api. These are
wrappers around the same functions added to the atf-c-api library.
* Added the ATF_CHECK_MATCH, ATF_CHECK_MATCH_MSG, ATF_REQUIRE_MATCH and
ATF_REQUIRE_MATCH_MSG macros to atf-c to simplify the validation of a
string against a regular expression.
* Miscellaneous fixes for manpage typos and compilation problems with
clang.
* Added caching of the results of those configure tests that rely on
executing a test program. This should help crossbuild systems by
providing a mechanism to pre-specify what the results should be.
* PR bin/45690: Make atf-report convert any non-printable characters to
a plain-text representation (matching their corresponding hexadecimal
entities) in XML output files. This is to prevent the output of test
cases from breaking xsltproc later.
Changes in version 0.16
***********************
Experimental version released on July 10th, 2012.
* Added a --enable-tools flag to configure to request the build of the
deprecated ATF tools, whose build is now disabled by default. In order
to continue running tests, you should migrate to Kyua instead of enabling
the build of the deprecated tools. The kyua-atf-compat package provides
transitional compatibility versions of atf-run and atf-report built on
top of Kyua.
* Tweaked the ATF_TEST_CASE macro of atf-c++ so that the compiler can
detect defined but unused test cases.
* PR bin/45859: Fixed some XSLT bugs that resulted in the tc-time and
tp-time XML tags leaking into the generated HTML file. Also improved
the CSS file slightly to correct alignment and color issues with the
timestamps column.
* Optimized atf-c++/macros.hpp so that GNU G++ consumes less memory during
compilation with GNU G++.
* Flipped the default to building shared libraries for atf-c and atf-c++,
and started versioning them. As a side-effect, this removes the
--enable-unstable-shared flag from configure that appears to not work any
more (under NetBSD). Additionally, some distributions require the use of
shared libraries for proper dependency tracking (e.g. Fedora), so it is
better if we do the right versioning upstream.
* Project hosting moved from an adhoc solution (custom web site and
Monotone repository) to Google Code (standard wiki and Git). ATF now
lives in a subcomponent of the Kyua project.
Changes in version 0.15
***********************
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.
Changes in version 0.14
***********************
Experimental version released on June 14th, 2011.
* Added a pkg-config file for atf-sh and an aclocal file to ease the
detection of atf-sh from autoconf scripts.
* Made the default test case body defined by atf_sh fail. This is to
ensure that test cases are properly defined in test programs and helps
in catching typos in the names of the body functions.
* PR bin/44882: Made atf-run connect the stdin of test cases to /dev/zero.
This provides more consistent results with "normal" execution (in
particular, when tests are executed detached from a terminal).
* Made atf-run hardcode TZ=UTC for test cases. It used to undefine TZ, but
that does not take into account that libc determines the current timezone
from a configuration file.
* All test programs will now print a warning when they are not run through
atf-run(1) stating that this is unsupported and may deliver incorrect
results.
* Added support for the 'require.files' test-case property. This allows
test cases to specify installed files that must be present for the test
case to run.
Changes in version 0.13
***********************
Experimental version released on March 31st, 2011.
This is the first release after the creation of the Kyua project, a more
modular and reliable replacement for ATF. From now on, ATF will change to
accomodate the transition to this new codebase, but ATF will still continue
to see development in the short/medium term. Check out the project page at
http://code.google.com/p/kyua/ for more details.
The changes in this release are:
* Added support to run the tests with the Kyua runtime engine (kyua-cli), a
new package that aims to replace atf-run and atf-report. The ATF tests
can be run with the new system by issuing a 'make installcheck-kyua' from
the top-level directory of the project (assuming the 'kyua' binary is
available during the configuration stage of ATF).
* atf-run and atf-report are now in maintenance mode (but *not* deprecated
yet!). Kyua already implements a new, much more reliable runtime engine
that provides similar features to these tools. That said, it is not
complete yet so all development efforts should go towards it.
* If GDB is installed, atf-run dumps the stack trace of crashing test
programs in an attempt to aid debugging. Contributed by Antti Kantee.
* Reverted default timeout change in previous release and reset its value
to 5 minutes. This was causing several issues, specially when running
the existing NetBSD test suite in qemu.
* Fixed the 'match' output checker in atf-check to properly validate the
last line of a file even if it does not have a newline.
* Added the ATF_REQUIRE_IN and ATF_REQUIRE_NOT_IN macros to atf-c++ to
check for the presence (or lack thereof) of an element in a collection.
* PR bin/44176: Fixed a race condition in atf-run that would crash atf-run
when the cleanup of a test case triggered asynchronous modifications to
its work directory (e.g. killing a daemon process that cleans up a pid
file in the work directory).
* PR bin/44301: Fixed the sample XSLT file to report bogus test programs
instead of just listing them as having 0 test cases.
Changes in version 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.
Changes in version 0.11
***********************
Experimental version released on October 20th, 2010.
* The ATF_CHECK* macros in atf-c++ were renamed to ATF_REQUIRE* to match
their counterparts in atf-c.
* Clearly separated the modules in atf-c that are supposed to be public
from those that are implementation details. The header files for the
internal modules are not installed any more.
* Made the atf-check tool private. It is only required by atf-sh and being
public has the danger of causing confusion. Also, making it private
simplifies the public API of atf.
* Changed atf-sh to enable per-command error checking (set -e) by default.
This catches many cases in which a test case is broken but it is not
reported as such because execution continues.
* Fixed the XSTL and CSS stylesheets to support expected failures.
Changes in version 0.10
***********************
Experimental version released on July 2nd, 2010.
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.
Changes in version 0.9
**********************
Experimental version released on June 3rd, 2010.
* Added atf-sh, an interpreter to process test programs written using
the shell API. This is not really a shell interpreter by itself though:
it is just a wrapper around the system shell that eases the loading of
the necessary ATF libraries.
* Removed atf-compile in favour of atf-sh.
* Added the use.fs metadata property to test case, which is used to
specify which test cases require file system access. This is to
highlight dependencies on external resources more clearly and to speed up
the execution of test suites by skipping the creation of many unnecessary
work directories.
* Fixed test programs to get a sane default value for their source
directory. This means that it should not be necessary any more to pass
-s when running test programs that do not live in the current directory.
* Defining test case headers became optional. This is trivial to achieve
in shell-based tests but a bit ugly in C and C++. In C, use the new
ATF_TC_WITHOUT_HEAD macro to define the test case, and in C++ use
ATF_TEST_CASE_WITHOUT_HEAD.
Changes in version 0.8
**********************
Experimental version released on May 7th, 2010.
* Test programs no longer run several test cases in a row. The execution
of a test program now requires a test case name, and that single test
case is executed. To execute several test cases, use the atf-run utility
as usual.
* Test programs no longer fork a subprocess to isolate the execution of
test cases. They run the test case code in-process, and a crash of the
test case will result in a crash of the test program. This is to ease
debugging of faulty test cases.
* Test programs no longer isolate their test cases. This means that they
will not create temporary directories nor sanitize the environment any
more. Yes: running a test case that depends on system state by hand will
most likely yield different results depending on where (machine,
directory, user environment, etc.) it is run. Isolation has been moved
to atf-run.
* Test programs no longer print a cryptic format (application/X-atf-tcs)
on a special file channel. They can now print whatever they want on the
screen. Because test programs can now only run one test case every time,
providing controlled output is not necessary any more.
* Test programs no longer write their status into a special file
descriptor. Instead, they create a file with the results, which is later
parsed by atf-run. This changes the semantics of the -r flag.
* atf-run has been adjusted to perform the test case isolation. As a
result, there is now a single canonical place that implements the
isolation of test caes. In previous releases, the three language
bindings (C, C++ and shell) had to be kept in sync with each other (read:
not a nice thing to do at all). As a side effect of this change, writing
bindings for other languages will be much, much easier from now on.
* atf-run forks test programs on a test case basis, instead of on a test
program basis as it did before. This is to provide the test case
isolation that was before implemented by the test programs themselves.
* Removed the atf-exec tool. This was used to implement test case
isolation in atf-sh, but it is now unnecessary.
* It is now optional to define the descr meta-data property. It has been
proven to be mostly useless, because test cases often carry a descriptive
name of their own.
Changes in version 0.7
**********************
Experimental version released on December 22nd, 2009.
* Added build-time checks to atf-c and atf-c++. A binding for atf-sh
will come later.
* Migrated all build-time checks for header files to proper ATF tests.
This demonstrates the use of the new feature described above.
* Added an internal API for child process management.
* Converted all plain-text distribution documents to a Docbook canonical
version, and include pre-generated plain text and HTML copies in the
distribution file.
* Simplified the contents of the Makefile.am by regenerating it from a
canonical Makefile.am.m4 source. As a side-effect, some dependency
specifications were fixed.
* Migrated all checks from the check target to installcheck, as these
require ATF to be installed.
* Fixed sign comparison mismatches triggered by the now-enabled
-Wsign-compare.
* Fixed many memory and object leaks.
Changes in version 0.6
**********************
Experimental version released on January 18th, 2009.
* Make atf-exec be able to kill its child process after a certain period
of time; this is controlled through the new -t option.
* Change atf-sh to use atf-exec's -t option to control the test case's
timeouts, instead of doing it internally. Same behavior as before, but
noticeably faster.
* atf-exec's -g option and atf-killpg are gone due to the previous
change.
* Added the atf-check(1) tool, a program that executes a given command
and checks its exit code against a known value and allows the management
of stdout and stderr in multiple ways. This replaces the previous
atf_check function in the atf-sh library and exposes this functionality
to both atf-c and atf-c++.
* Added the ATF_REQUIRE family of macros to the C interface. These help
in checking for fatal test conditions. The old ATF_CHECK macros now
perform non-fatal checks only. I.e. by using ATF_CHECK, the test case
can now continue its execution and the failures will not be reported
until the end of the whole run.
* Extended the amount of ATF_CHECK_* C macros with new ones to provide
more features to the developer. These also have their corresponding
counterparts in the ATF_REQUIRE_* family. The new macros (listing the
suffixes only) are: _EQ (replaces _EQUAL), _EQ_MSG, _STREQ and
_STREQ_MSG.
Changes in version 0.5
**********************
Experimental version released on May 1st, 2008.
* Clauses 3 and 4 of the BSD license used by the project were dropped.
All the code is now under a 2-clause BSD license compatible with the GNU
General Public License (GPL).
* Added a C-only binding so that binary test programs do not need to be
tied to C++ at all. This binding is now known as the atf-c library.
* Renamed the C++ binding to atf-c++ for consistency with the new atf-c.
* Renamed the POSIX shell binding to atf-sh for consistency with the new
atf-c and atf-c++.
* Added a -w flag to test programs through which it is possible to
specify the work directory to be used. This was possible in prior
releases by defining the workdir configuration variable (-v workdir=...),
but was a conceptually incorrect mechanism.
* Test programs now preserve the execution order of test cases when they
are given in the command line. Even those mentioned more than once are
executed multiple times to comply with the user's requests.
Changes in version 0.4
**********************
Experimental version released on February 4th, 2008.
* Added two new manual pages, atf-c++-api and atf-sh-api, describing the
C++ and POSIX shell interfaces used to write test programs.
* Added a pkg-config file, useful to get the flags to build against the
C++ library or to easily detect the presence of ATF.
* Added a way for test cases to require a specific architecture and/or
machine type through the new 'require.arch' and 'require.machine'
meta-data properties, respectively.
* Added the 'timeout' property to test cases, useful to set an
upper-bound limit for the test's run time and thus prevent global test
program stalls due to the test case's misbehavior.
* Added the atf-exec(1) internal utility, used to execute a command
after changing the process group it belongs to.
* Added the atf-killpg(1) internal utility, used to kill process groups.
* Multiple portability fixes. Of special interest, full support for
SunOS (Solaris Express Developer Edition 2007/09) using the Sun Studio 12
C++ compiler.
* Fixed a serious bug that prevented atf-run(1) from working at all
under Fedora 8 x86_64. Due to the nature of the bug, other platforms
were likely affected too.
Changes in version 0.3
**********************
Experimental version released on November 11th, 2007.
* Added XML output support to atf-report. This is accompanied by a DTD
for the format's structure and sample XSLT/CSS files to post-process this
output and convert it to a plain HTML report.
* Changed atf-run to add system information to the report it generates.
This is currently used by atf-report's XML output only, and is later
printed in the HTML reports in a nice and useful summary table. The user
and system administrator are allowed to tune this feature by means of
hooks.
* Removed the test cases' 'isolated' property. This was intended to
avoid touching the file system at all when running the related test case,
but this has not been true for a long while: some control files are
unconditionally required for several purposes, and we cannot easily get
rid of them. This way we remove several critical and delicate pieces of
code.
* Improved atf-report's CSV output format to include information about
test programs too.
* Fixed the tests that used atf-compile to not require this tool as a
helper. Avoids systems without build-time utilities to skip many tests
that could otherwise be run. (E.g. NetBSD without the comp.tgz set
installed.)
* Many general cleanups: Fixed many pieces of code marked as ugly and/or
incomplete.
Changes in version 0.2
**********************
Experimental version released on September 20th, 2007.
* Test cases now get a known umask on entry.
* atf-run now detects many unexpected failures caused by test programs and
reports them as bogus tests. atf-report is able to handle these new
errors and nicely reports them to the user.
* All the data formats read and written by the tools have been
documented and cleaned up. These include those grammars that define how
the different components communicate with each other as well as the
format of files written by the developers and users: the Atffiles and the
configuration files.
* Added the atf-version tool, a utility that displays information about
the currently installed version of ATF.
* Test cases can now define an optional cleanup routine to undo their
actions regardless of their exit status.
* atf-report now summarizes the list of failed (bogus) test programs
when using the ticker output format.
* Test programs now capture some termination signals and clean up any
temporary files before exiting the program.
* Multiple bug fixes and improvements all around.
Changes in version 0.1
**********************
Experimental version released on August 20th, 2007.
* First public version. This was released coinciding with the end of the
Google Summer of Code 2007 program.
