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.
- Recognize -C for pkg_add like the rest of the tools do
- Do the existing check for pkg_add -f, it makes the combination of
-f and -U a bit less surprising
- Fix option handling for CHECK_VULNERABILITIES (from spz@)
- Make end-of-life check the default. pkg_install.conf(5) can be used
to override the default. The existing admin -e & co continue to work as
before.
- kill MKPIGZ.
- add MKPIGZGZIP. if it is "no", then only install pigz as pigz. if it is
not "no", don't install mrgzip, install pigz as gzip.
in all cases, the z* scripts.
i don't like the name MKPIGZGZIP so if anyone has a better name, feel free
to replace it. i don't care enough since killing the ugly name is just
more incentive to get pigz doing .bz2, .Z and .z.
- Improved before-queue content filter performance. With
"smtpd_proxy_options = speed_adjust", the Postfix SMTP server
receives the entire message before it connects to a before-queue
content filter. Typically, this allows Postfix to handle the same
mail load with fewer content filter processes.
- Improved address verification performance. The verify database is now
persistent by default, and it is automatically cleaned periodically. Under
overload conditions, the Postfix SMTP server no longer waits up to 6 seconds
for an address probe to complete.
- Support for reputation management based on the local SMTP client IP address.
This is typically implemented with "FILTER transportname:" actions in access
maps or header/body checks, and mail delivery transports in master.cf with
unique smtp_bind_address values.

which are known to fail, e.g.:
atf_tc_set_md_var(tc, "xfail", "PR kern/43456");
Expected failures do not count towards the ultimate pass/fail result
from the test run:
pain-rustique:39:~/<2>src/tests/fs/ptyfs> atf-run t_nullpts | atf-report
Tests root: /home/pooka/src/wholesrc2/src/tests/fs/ptyfs
t_nullpts (1/1): 1 test cases
nullrevoke: Expected failure: PR kern/43456
Summary for 1 test programs:
0 passed test cases.
0 failed test cases.
1 expected failures.
0 skipped test cases.
pain-rustique:40:~/<2>src/tests/fs/ptyfs> echo $?
0
However, an xfail test which passes will count as a failure, i.e.
xfail inverts test case success/fail. This way we can get a better
sense from the ultimate verdict of the NetBSD atf run by seeing if
there were any unexpected failures, i.e. new regressions.
This feature will be present in the upcoming atf 0.10 release,
possibly with finer grained control.
patch reviewed by jmmv
----------
Fix detection of crashed test cases
Prevent cross-test-case contamination that occured when a first test case
passed and the second crashed. The second could pick up the result of the
first test case and not be reported as failed.
Similarly, change the way timed out test cases are reported back to the
caller. The creation of a temporary results file was just a really stupid
way of passing information around and introduced false positives if the
test case creates a results file before timing out.
Fixes ticket #35.
----------
Problem originally reported by pooka@.
* Fix crash when using clientid and the interface re-configures
* log the pid of dhcpcd
* Indicate server IP received message from even if server ID not
present
* Fix crashes on IPv4LL failure and add more logging
* 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.
bugfixes and feature additions, full changelog is below. The major
feature I think was the GCC compatibility which is now enabled by
default, with many of the commonly used GCC attributes and builtin
functions now supported, and pcc defines __GNUC__ as version 4.3
This version can build all of bin/, sbin/ and games/ except for dab(5),
with only a few outstanding issues in usr.bin/ and usr.sbin/. There are
still issues with PIC code generation (affects building libraries, on
i386 at least) and I have not tried applying pcc to kernel builds.
ChangeLog, in most-recent first order, screen-scraped from
http://pcc.ludd.ltu.se/fisheye/changelog/pcc
Each paragraph is a separate commit, the [xxx] refers to the module
that the following commits were in:
[ccom]
Fix designated initializer bug as reported by Iain Hibbert on pcc-list.
Put in prototype for dainit() to avoid warnings when using yacc.
Discard parameter attributes, they ended up to be handled as arguments
otherwise. Suppose to fix Jira#PCC-132 by Iain Hibbert.
Rewrite __builtin_offsetof() to handle non-constant array offset values.
This actually made the offsetof code much simpler.
Requested by Iain Hibbert on pcc-list.
Op DOT will be BINODE.
Support gcc ugly construction a?:b, as discussed on pcc-list.
Add gcc compat range initializers, reported by Iain Hibbert.
[amd64]
Do not put eax as hidden argument if not needed.
Better support for the Intel addressing modes. Now ByteBench only takes
77% of the earlier time to complete.
[mip]
Do not base hash functions on memory addresses. These addresses may
change between different compilations and we want predictability.
Also check if an address of a node is lower than expected to avoid
short-range temporaries in the Freeze() code.
[i386]
Clear flags field on TEMP nodes so that function pointers will get their
stack adjusted afterwards, otherwise there might be junk left.
[ccom]
Aet alignment to at least ALCHAR for structs when passing them over to
pass2. Failure to do so caused bug spotted by Iain Hibbert.
[sparc64]
Fix string init bug, from Lars Zetterlund.
[mip]
Declare printip2() as static function for whole file, as pointed out by
Iain Hibbert.
[ccom]
Make the canary value on stack volatile, so that the compiler won't
try to put it into a register. Solves stack overwrite error reported
by Iain Hibbert on pcc-list.
[i386]
Fix uninitialized member bug in picsymtab breaking -k -g. Suppose to fix
Jira#PCC-138 by Nicolas Joly, patch provided by Iain Hibbert.
[ccom]
Tell scan to ignore typedefs of the same names goto labels. Fixes
Jira#PCC-141 by Andreas Kaiser with recommended fix from him.
[mip]
Run deljumps again after the ssa pass to cleanup the code before doing
register allocation.
[mip]
Do liveness analysis before turning a function into SSA code, and later
use that to to find out whether we need to insert a phi function or not.
This is usually called "Pruned SSA".
Now the SSA code tend to be significantly better quality.
Fix deljumps label updating bug.
Remove statements that are moves to itself in deljumps.
[libpcc]
Define _VA_LIST_DEFINED for compatibility eglibc headers.
From tg@mirbsd.de.
[ccom]
Ensure CM towers are built to the left, fixes parsing bug pointed put
by Jonathan Gray. Also add "used" attribute.
[mip]
Teach dce() to remove ip structs without destroying the basic block
structure.
[ccom]
Check if type is an array before checking its dimension. Fixes bug
reported by Iain Hibbert on pcc-list.
[i386]
Tell table to prefer 2-op insns before 3-op.
Do not try to match args on builtins.
[mip]
Do not favorize 3-op instruction in the ssa case, simple statements
like i++ have been rewritten to t1 = t2 + 1 and we want the register
allocator to try to put t1 and t2 in the same register if there are
2-op insns.
Help coloring algorithm by at the time of assigning registers see if
there are any frozen moves to nodes that have already got their color
and we can give this node the same register.
This will avoid unneccessary moves.
Move list init into the function that initializes it.
Put two more variables into p2env, to have a cleaner way of passing
information in the optimizer phase.
Fix broken indentation.
Do not put a move on the move list more than once.
Count precolored nodes as infinite K, not 0, otherwise it may make
colorable graphs uncolorable when there are many moves.
[ccom]
Fix reporting on bogus error of struct parameters, as reported by Iain
Hibbert on pcc-list.
[amd64]
Remove cast of pointer converted ints, not needed on amd64. Fixes
Jira#PCC-136 by Nicholas Joly.
[ccom]
Add and handle gcc attribute __warn_unused_result__. Requested by Iain
Hibbert but with a different implementation.
Do not allow initialization of multi-dimension incomplete arrays, fixes
bug reported by Jesus Sanchez on pcc-list.
Also fix another bug spotted, which had as a result that dynamic-sized
arrays initialized by strings did not become null-terminated.
[amd64]
amd64 cannot handle imemdiate constants for 64-bit simple ops.
Fixes Jira#PCC-134 by Nicolas Joly.
[ccom]
Allow any expression inside typeof. Supposes to fix Jira#PCC-135

return value is ignored; the float stack must be popped anyway.
FIxes a bug in awk where the float stack overflows.
[ccom]
Clear out symtab pointers for NAME and ICON nodes in functions to
be inlined, since accessing them will result in crashes. Fixes
stdcall/ccall bugs reported by Iain Hibbert.

[ccom]
Remove redundant GETSUE() define, from Iain Hibbert.

Fixes Jira#PCC-129 by Iain Hibbert.
Fix checking of struct sizes. Solves Jira#PCC-128 by Iain Hibbert.

be treated as wide strings in __func__. Patch from Iain Hibbert.
[amd64]
Add last memcpy for function returning structs. Should be complete now.
[configure]
Set default wchar type to int instead of unsigned.
[cc]
Fix wchar defines as requested by Iain Hibbert.
[cpp]

Forgot to null-terminate yytext. Bug pointed out by Iain Hibbert.
[ccom]
No reason not to allow pointers larger than LONG, as pointed out by
Peter Kuschnerus.

reported by Peter Kuschnerus.
[amd64]
Add arg count index to builtin switch table.
[ccom]

Add huge/inf/nan builtins as requested by Iain Hibbert.
Also add a generic builtin function, based on a slightly modified
version of a patch by Iain Hibbert.
Add another cast routine which will cast without adding a "cast" and
therefore it will complain if it's a bad cast (like int to pointer).
[amd64]
Fix bugs where int should be long. Fixes Jira#PCC-125 by Nicholas Joly.
[ccom]
Break out buintins to their own file. Common argument count check
for builtins. Should have argument cast checks here also.
[i386]
Add support for attribute "visibility".
[amd64]
Do not emit visibility type "default" since it's ``default''.
Print out visibility directives for as.
[ccom]
Add attribute support for visibility per patch from Iain Hibbert.

Add support for variable renaming when assingning; i.e.
int foo asm("bar") = 2;
and not only
int foo asm("bar");
Should fix Jira#PCC-116 by Altamiranus.
Add support for attribute modes SF, DF, byte, word, pointer.
Should fix Jira#PCC-114 by Altamiranus.

away if not gcc.
[mip]

man pages to use mandoc unconditional as it gives reasonable output for

of keeping UTC, and handle timezones the way we handled them before (CRON_TZ).
The old behavior can be selected with defining CRON_LOCALTIME.
- Provide functions to pretty-print crontab entries.
* atof-generic.c (atof_generic): recognize snan and qnan in
addition to nan and inf.
* atof-vax.c (flonum_gen2vax): deal properly with nan, snan, qnan,
and +Inf and -Inf codes.
This fixes PR toolchain/43303.
* 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.
forth. This resolves CVE-2009-3563, but it should be noted that nobody uses
this code so far, so this is more of a preventive update than a security
one.
Fix an off-by-one in the check for properly sized pkgdb entries.
It rejected perfectly valid entries.
Extract dependencies of libarchive from the pkgconfig file and thereby
drop knowledge of the needed libraries.
At least some versions of HP-UX are known to not support %zu, add a
workaround. This is using the black list approach for now.
Recognize xz as compression type for pkg_create.
The first time an error is hit while fetching packages, try to reget
from the same position. This works around the server closing the
connection while fetching dependencies.
Try to detect common forms of pkgdb corruption and issue a warning in
that case.
Refactor the pkg_vulnerabilities logic to use the compression support
from libarchive. This reduces the amount zlib/bzip2 interaction to
the linkage.
Add man pages for audit-packages and download-vulnerability-list which
point to pkg_admin and notes that the scripts are obsolete.
define REG_STARTEND
include tre-config.h inplace in tre.h, since it is small, always gets
included anyway, and this means that we don't have to install tre-config.h

it belongs in a separate elf_nbsd.sh, included from elf_i386_nbsd.sh.
The problem is described in:
https://bugzilla.redhat.com/show_bug.cgi?id=492183#c7, namely if
all the sections are not defined in the ld script, it can screw
up. This happens when building /usr/src/usr.sbin.crash with
MKPIE=yes. Thanks to Piotr Meyer for the report and analysis.
We don't need to fix any other archs yet (because crash only works on i386),
but we should. skrll should look into it, please :-)
- "postmulti -p command" did not skip disabled instances.
- In the multi_instance_wrapper parameter, the expansion of
$command_directory and $daemon_directory was broken.
- The address_verify_poll_count parameter value was not made
stress-dependent by default. This defeated the purpose of making other
settings stress-dependent by default with Postfix 2.6.
- Milter applications would hang up after receiving an unexpected
SMFIC_HEADER (mail header) command. This problem happened with Milters
that (legitimately) do not send replies for SMFIC_RCPT (recipient
address) or SMFIC_DATA (start of message) commands.
- Core dump while an printing error message for a malformed %<letter>
sequence in LDAP, MySQL or PostgreSQL lookup table configuration.
- Mail with zero recipients was forever stuck in the queue. This happened
when "postsuper -r" was run after all the recipients of a message were
delivered (or bounced), but before the message was deleted from the queue.
- With hostnames such as 1-2-3-4, the valid_hostname() fuction did not
recognize the '-' as a non-numeric character, causing a legitimate name
to be rejected as "invalid".
- The VRFY command did not accept a mailbox address inside <>.
