We no longer write manual ChangeLog entries since they are
auto-generated at release time. Drop dependency of the `make dist`
target on the file and document the fact that the latest ChangeLog
entries can be read in the highest numbered ChangeLog.N file in
ChangeLog.old.
The ChangeLog.old/ChangeLog.20 file for 2.31 will thus be generated
just before tagging a release.

Debugging programs that have been dynamically linked against an
uninstalled glibc requires unusual steps, such as letting gdb know where
the thread db library is located and explicitly calling the loader.
However, when the program under test is statically linked, these steps
are not required (as a matter of fact, using the dynamic loader to run a
statically linked program is wrong and will fail), and gdb should be
called the usual way.
This patch modifies debugglibc.sh so that it checks if the program under
test is statically linked, then runs the debugger appropriately.

Some test cases are meant to be ran inside the container infrastructure
and make check automatically runs them as such. However, running a
single test case in a container without make check is useful.
This patch adds a new --tool option to testrun.sh that makes this easy,
as well as it adds a new option (-c or --in-container) to debugglibc.sh,
which causes the program under test to be ran in a container (with
WAIT_FOR_DEBUGGER=1), then automatically attaches GDB to it.
Automatically detecting if a test case is supposed to be ran inside a
container is harder (if not impossible), as Carlos pointed out [1],
however, this patch makes it easier to do it manually:
Using testrun.sh with containerized test:
$ ./testrun.sh --tool=container /absolute/path/to/program
Using debugglibc.sh with containerized test:
$ ./debugglibc.sh -c /absolute/path/to/program
Note: running these commands with relative paths causes error and
warning messages to be displayed, although the test case might succeed.
For example, with relative path:
$ ./testrun.sh --tool=container elf/tst-ldconfig-bad-aux-cache
error: subprocess failed: execv
error: unexpected error output from subprocess
/sbin/ldconfig: Warning: ignoring configuration file that cannot be opened: /etc/ld.so.conf: No such file or directory
info: f 0 1064 /var/cache/ldconfig/aux-cache 20 aux-cache
[...]
Whereas with absolute paths, the errors and warnings are gone:
$ ./testrun.sh --tool=container $PWD/elf/tst-ldconfig-bad-aux-cache
info: f 0 1064 /var/cache/ldconfig/aux-cache 20 aux-cache

The `test' make target passes a trailing slash in the subdir argument. This
does not play well with elf/rtld-Rules which looks for `elf' without any
trailing slash, and therefore doesn't find a match when running an elf test
individually. This commit removes the trailing slash from the invocation.

The testroot does not have a gunzip command, so the charmap files
should not be installed gzipped else they cannot be used (and thus
tested). With this patch, installing with INSTALL_UNCOMPRESSED=yes
installs uncompressed charmaps instead.
Note that we must purge the $(symbolic_link_list) as it contains
references to $(DESTDIR), which we change during the testroot
installation.

This patch addresses an issue reported in
<https://sourceware.org/ml/libc-alpha/2019-07/msg00661.html> where the
creation of testroot.pristine, on encountering
LD_TRACE_LOADED_OBJECTS=1 of the form
libc.so.6 => /scratch/jmyers/glibc/mbs/obj/glibc-8-0-mips64-linux-gnu-x86_64-linux-gnu/default/libc.so.6 (0x772dd000)
/lib32/ld.so.1 => /scratch/jmyers/glibc/mbs/obj/glibc-8-0-mips64-linux-gnu-x86_64-linux-gnu/default/elf/ld.so.1 (0x7747b000)
tries to copy /lib32/ld.so.1 (which does not exist) into the testroot
instead of copying the path on the RHS of "=>", which does exist,
because the Makefile logic assumes that the path on such a line with
'/' should be copied, when if there are such paths on both the LHS and
the RHS of "=>", only the one on the RHS necessarily exists and so
only that should be copied. The patch follows the approach suggested
by DJ in <https://sourceware.org/ml/libc-alpha/2019-07/msg00662.html>,
with the suggestion from Andreas in
<https://sourceware.org/ml/libc-alpha/2019-10/msg00514.html> of a
single sed command in place of pipeline of grep and three sed
commands.
Tested for x86_64, with and without --enable-hardcoded-path-in-tests;
a previous version with multiple sed commands, implementing the same
logic, also tested for MIPS, with and without
--enable-hardcoded-path-in-tests, to confirm it fixes the original
problem.

This patch adds the ability to run debugglibc.sh's inferior program with
arguments specified on the command line. This enables convenient debugging
of non-testcase programs such as iconv/iconv_prog or other dynamically
linked programs. Program arguments may be passed using `--' as a separator.
For example:
$ ./debugglibc.sh -b iconv -- iconv/iconv_prog -f ASCII -t UTF-8 input.txt

This patch adds a new make rule that generates a helper script for
debugging glibc test cases. The new script, debugglibc.sh, is similar
to testrun.sh, in the sense that it allows the execution of the
specified test case, however, it opens the test case in GDB, setting the
library path the same way that testrun.sh does. The commands are based
on the instructions on the wiki for glibc debugging [1,2].
By default, the script tells GDB to load the test case for symbol
information, so that, when a breakpoint is hit, the call stack is
displayed correctly (instead of printing lots of '??'s). For instance,
after running 'make' and 'make check', one could do the following:
$ ./debugglibc.sh nptl/tst-exec1 -b pthread_join
Reading symbols from /home/gabriel/build/powerpc64le/glibc//elf/ld.so...done.
Breakpoint 1 at 0x1444

Breakpoint 2 at 0x7ffff7f49d48: file pthread_join.c, line 23.
Notice that the script will always start GDB with the program running
and halted at _dl_start_user. So, in order to reach the actual
breakpoint of interest, one should hit 'c', not 'r':
>>> c

Commit 35e038c1d2ccb3a75395662f9c4f28d85a61444f started to use an

* Makefile (testroot.pristine/install.stamp): Pass

Whenever a sub-make is created, it inherits the variable subdirs from its
parent. This is also true when make check is called with a restricted
list of subdirs. In this scenario, make install is executed "partially"
and testroot.pristine ends up with an incomplete installation.

Some DSOs are distributed in hardware capability directories, e.g.
/usr/lib64/power7/libc.so.6
Whenever the processor is able to use one of these hardware-enabled
DSOs, testroot.pristine ends up with copies of glibc-provided libraries
from the system because it can't overwrite or remove them.
This patch avoids the unintended copies by executing ld.so with the same
arguments passed to each glibc test.
* Makefile (testroot.pristine/install.stamp): Execute ld.so with
the same arguments used in all tests.

If building on a subset of architectures only, it is easy to miss
wrapper headers which are required by other architectures because
they lack the corresponding sysdeps header. The check ensures
that every installed header which is not itself a sysdeps header
has a header under include/ (that presumably wraps the header,
and perhaps also adding declarations and definitions for !_ISOMAC).
Also check for the absence of the sysdeps/generic/bits directory
removed in commit c72565e5f1124c2dc72573e83406fe999e56091f, to make
accidental re-introduction more difficult.

I noticed that, now that build-many-glibcs.py no longer copies glibc
sources, I was getting core dumps in my glibc source directories. The
cause appears to be, from the i686-gnu build:
for dso in ` env LD_TRACE_LOADED_OBJECTS=1 \
/scratch/jmyers/glibc-bot/build/glibcs/i686-gnu/glibc/elf/ld.so.1 \
/scratch/jmyers/glibc-bot/build/glibcs/i686-gnu/glibc/testroot.pristine/bin/sh \
[...]
Segmentation fault (core dumped)
In this case, the x86 architecture means the binary executes, but
dumps core rather than actually working.
Anything involving running the newly built glibc should only be done

part of the testroot setup accordingly.

glibc has an add-ons mechanism to allow additional software to be
integrated into the glibc build. Such add-ons may be within the glibc
source tree, or outside it at a path passed to the --enable-add-ons
configure option.
localedata and crypt were once add-ons, distributed in separate
release tarballs, but long since stopped using that mechanism.
Linuxthreads was always an add-on. Ports spent some time as an add-on
with separate release tarballs, then was first moved into the glibc
source tree, then had its sysdeps files moved into the main sysdeps
hierarchy so the add-ons mechanism was no longer used. NPTL spent
some time as an add-on in the main glibc tree before stopping using
the add-on mechanism. libidn used to have separate release tarballs
but no longer does so, but still uses the add-ons mechanism within the
glibc source tree. Various other software has supported building with
the add-ons mechanism at times in the past, but I don't think any is
still widely used.
Add-ons involve significant, little-used complexity in the glibc build
system, and make it hard to understand what the space of possible
glibc configurations is. This patch removes the add-ons mechanism.
libidn is now built via the Subdirs mechanism to cause any
configuration using sysdeps/unix/inet to build libidn; HAVE_LIBIDN
(which effectively means shared libraries are available) is now
defined via sysdeps/unix/inet/configure. Various references to
add-ons around the source tree are removed (in the case of maint.texi,
the example list of sysdeps directories is still very out of date).
Externally maintained ports should now put their files in the normal
sysdeps directory structure rather than being arranged as add-ons;
they probably need to change e.g. elf.h anyway, rather than actually
being able to work just as a drop-in subtree. Hurd libpthread should
be arranged similarly to NPTL, so some files might go in a
hurd-pthreads (or similar) top-level directory in glibc, while sysdeps
files should go in the normal sysdeps directory structure (possibly in
hurd or hurd-pthreads subdirectories, just as there are nptl
subdirectories in the sysdeps tree).

This patch adds a new build module called 'testsuite'.
IS_IN (testsuite) implies _ISOMAC, as do IS_IN_build and __cplusplus
(which means several ad-hoc tests for __cplusplus can go away).
libc-symbols.h now suppresses almost all of *itself* when _ISOMAC is
defined; in particular, _ISOMAC mode does not get config.h
automatically anymore.
There are still quite a few tests that need to see internal gunk of
one variety or another. For them, we now have 'tests-internal' and
'test-internal-extras'; files in this category will still be compiled
with MODULE_NAME=nonlib, and everything proceeds as it always has.
The bulk of this patch is moving tests from 'tests' to
'tests-internal'. There is also 'tests-static-internal', which has
the same effect on files in 'tests-static', and 'modules-names-tests',
which has the *inverse* effect on files in 'modules-names' (it's
inverted because most of the things in modules-names are *not* tests).
For both of these, the file must appear in *both* the new variable and
the old one.
There is also now a special case for when libc-symbols.h is included
without MODULE_NAME being defined at all. (This happens during the
creation of libc-modules.h, and also when preprocessing Versions
files.) When this happens, IS_IN is set to be always false and
_ISOMAC is *not* defined, which was the status quo, but now it's
explicit.
The remaining changes to C source files in this patch seemed likely to
cause problems in the absence of the main change. They should be
relatively self-explanatory. In a few cases I duplicated a definition
from an internal header rather than move the test to tests-internal;
this was a judgement call each time and I'm happy to change those
however reviewers feel is more appropriate.
* Makerules: New subdir configuration variables 'tests-internal'
and 'test-internal-extras'. Test files in these categories will
still be compiled with MODULE_NAME=nonlib. Test files in the
existing categories (tests, xtests, test-srcs, test-extras) are
now compiled with MODULE_NAME=testsuite.
New subdir configuration variable 'modules-names-tests'. Files
which are in both 'modules-names' and 'modules-names-tests' will
be compiled with MODULE_NAME=testsuite instead of
MODULE_NAME=extramodules.

* include/libc-symbols.h: Move definitions of _GNU_SOURCE,

very top of the file and rationalize their order.
If MODULE_NAME is not defined at all, define IS_IN to always be
false, and don't define _ISOMAC.
If any of IS_IN (testsuite), IS_IN_build, or __cplusplus are
true, define _ISOMAC and suppress everything else in this file,
starting with the inclusion of config.h.
Do check for inappropriate definitions of __OPTIMIZE__ and
__FAST_MATH__ here, but only if _ISOMAC is not defined.
Correct some out-of-date commentary.
* include/math.h: If _ISOMAC is defined, undefine NO_LONG_DOUBLE
and _Mlong_double_ before including math.h.

_STRING_ARCH_unaligned. Move a comment to a more appropriate
location.

glibc headers include some code (not particularly consistent or
systematic) to put various declarations in C++ namespaces std and
__c99, if _GLIBCPP_USE_NAMESPACES is defined.
As noted in <https://gcc.gnu.org/ml/libstdc++/2017-03/msg00025.html>,
this macro was removed from libstdc++ in 2000. I don't expect
compilation with such old versions of libstdc++ to work with current
glibc headers anyway (whereas old *binaries* are expected to stay
working with current glibc); this patch (which should be a no-op with
any libstdc++ version postdating that removal) removes all this code
from the glibc headers.
The begin-end-check.pl test, whose comments say it is about checking
these namespace macro calls, is also removed. The code in that test
would have covered __BEGIN_DECLS / __END_DECLS as well, but if those
weren't properly matched it would show up with the
check-installed-headers-cxx tests, so I don't think there is an actual
use for keeping begin-end-check.pl with the namespace code removed.
Tested for x86_64 and x86 (testsuite, and that installed stripped
shared libraries are unchanged by the patch).

This adds a test to ensure that the problems fixed in the last several
patches do not recur. Each directory checks the headers that it
installs for two properties: first, each header must be compilable in
isolation, as both C and C++, under a representative combination of
language and library conformance levels; second, there is a blacklist
of identifiers that may not appear in any installed header, currently
consisting of the legacy BSD typedefs. (There is an exemption for the
headers that define those typedefs, and for the RPC headers. It may be
necessary to make this more sophisticated if we add more stuff to the
blacklist in the future.)
In order for this test to work correctly, every wrapper header
that actually defines something must guard those definitions with
#ifndef _ISOMAC. This is the existing mechanism used by the conform/
tests to tell wrapper headers not to define anything that the public
header wouldn't, and not to use anything from libc-symbols.h. conform/
only cares for headers that we need to check for standards conformance,
whereas this test applies to *every* header. (Headers in include/ that
are either installed directly, or are internal-use-only and do *not*
correspond to any installed header, are not affected.)
* scripts/check-installed-headers.sh: New script.
* Rules: In each directory that defines header files to be installed,
run check-installed-headers.sh on them as a special test.
* Makefile: Likewise for the headers installed at top level.
