pwdx doesn't actually use any of the libprocps functions but
it is linked because it is the default. This specific LDADD
removes that unrequired linking.
Several Debian based distributions were recently found
to have omitted a kernel configuration option that had
the effect of rendering /proc/#/stat and /proc/#/wchan
useless for providing any 'sleeping in function' info.
That problem also prompted a reevaluation of the whole
approach to wchan matters which had grown increasingly
complex as our library evolved over the last 13 years.
The net result was a decision to rely on /proc/#/wchan
which arrived along with the 2.5 kernel. This then let
us vastly simplify the internal code plus the external
interface which will benefit both the top and ps pgms.

For the test suite, procps used to use sleep which would just
create a process or two to test the tools against. Some setups
coreutils creates all programs including sleep into one blob which
means a lot of the tests fail, see issue #2
procps has its own sleep program now.
Use LDADD or *_LDADD instead of AM_LDFLAGS to refer to libproc.la.
Otherwise, parallel builds will break as there is no explicit dependency
to ensure the library is built before the binaries that try to link to
it.
v2: Added empty rules lib_test_*_LDADD to remove the dependency on
libproc which is not used by the lib/test_* binaries.
Tested by running `make -jNN` repeatedly for different levels of
parallelism to ensure the build works. Also checked that `make check`
and `make distcheck` still work as expected. Also made sure that a
parallel make invocation works with `make -j distcheck`.

The "usrbin_execdir" hack meant to install some binaries in /bin and
others in /usr/bin. However:
- It is very inflexible: not much control on the final directory name
and it is not possible to get rid of the usr/bin suffix without
patching the build system.
- It is hard to use: it requires configure to receive --exec_prefix=/
and other settings do not make much sense. It is not very obvious that
that setting needs to be passed and it takes a while to figure it out.
- It produces garbage with the default setup: the default prefix of
/usr/local ends up installing the binaries under /usr/local/usr/bin
which does not make any sense.
Furthermore, the requirement to split binaries in /bin and /usr/bin is
not that strong since some distributions adopted the /usr merge and so
would agree to just deploy all binaries to /usr/bin directly.
Distributions that would still like to split /bin from /usr/bin should
actually move binaries such as `ps` and `kill` to /bin after the install
of procps-ng is complete. After all, they are the ones responsible for
determining what are the binaries that need to be in the root partition
and that list depends on their early boot init scripts, so it is
possible that the list must be augmented with other binaries from this
package.
Therefore, I propose here to get rid of that hack and simply install all
the binaries to bindir instead, which solves the problems described
above and simplifies the build and install of procps-ng.
Tested that it builds and both `make check` and `make distcheck` work.
Tested that `make install` works and produces the expected tree, the
only difference being the absence of the bogus /usr/local/usr/bin
directory and now all binaries are merged into /usr/local/bin as
expected.

Otherwise, automake 1.14 will warn that this option will become the
default in an upcoming release, which will cause problems for the
procps-ng build.
Now that the automake rules were merged in the top level Makefile.am,
it is possible to enable "subdir-objects" without breaking the build or
the dist.
Tested that it builds and both `make check` and `make distcheck` work.
Tested that `make install` works and produces the same tree before and
after this change. Confirmed that binaries are also placed in the same
locations in the build tree.

This will be required for subdir-objects, otherwise automake will have
problems with more than one Makefile.am having rules to build the same
files.
Tested that it builds and both `make check` and `make distcheck` work.
Tested `make install` and compared the tree with the one installed
before this commit, both installed the binaries to the same locations.
The binaries are also in the same location in the build tree (for
instance, ps/pscommand is still there.)
Checked the binaries for the correct libraries linked into them. Binary
sizes matched before and after this change.

This is cleaner and we need to match paths exactly when we enable the
subdir-objects automake option.
Out-of-tree builds still work since automake is smart to know these are
source files and that it needs to look for them in $(top_srcdir), so
there is no need to make this explicit.

This is required for out-of-tree build to work, since many source files
include e.g. proc/*.h which is not under the include/ directory.

The translated manpage generation has moved from scripts to
Makefiles. This asists with conditional building as well, no
need to regenerate the German pgrep man page if both
the original pgrep.1 and man-po/de.po is not changed.
My Makefile-fu fails me on producing a cross-product or double
iteration for languages and man pages. Until that is solved
each man page is explicitly built. No big deal but it doesn't
look elegant in the Makefile. Languages will be picked
up automatically if they are found in man-po, man-po/top or
man-po/ps
The README describes the three-step process for translating
the files, incase I forget or someone else wants to update them.
The pot files for man-po are part of the extra_dist target so are
built at dist time. These used to be created as part of the dist-hook.
However it is better to control their builds in the Makefile so they
are conditionally built. It also means distcheck doesn't complain when
they are added to the CLEANFILES.
distcheck failed because the man-po scripts weren't sourcing or
escaping the directories correctly.
This is a partial fix, but at least distcheck is happy.
The get-trans target rsyncs the latest copies of translation files
from the translation project. I put this target in because I always
forget the exact syntax of the command.

As the sysvinit becomes obsolete, some of the bundled tools
need to find a new home. The procps-ng project seems to be
the most suitable project for adopting the pidof tool.
This commit introduces a redesigned version of pidof
that satisfies the LSB requirements.
In corner cases the behaviour might differ from the former
one as the new version doesn't use any stat(2) calls.
In the same fashion of pgrep, introduce two new options:
--ns <pid>
- nslist <ns,...>
which allows processes to be filtered by namespace.
Signed-off-by: Aristeu Rozanski <arozansk@redhat.com>
A PID should be specified with --ns:
$ pgrep --ns 12345
which will only match the processes which belong to to the same 6
namespaces. It is also possible to specify which namespaces to test:
$ pgrep --ns 12345 --nslist mnt,net,ipc
which will match processes that belong to the same mount, network and
IPC namespaces as PID 12345.

If you configure w/out --enable-examples, then `make dist` doesn't

Two problems.
1) skill/snice : distribution doesnt mean install
If you don't set your configure flags right, you dont install the
skill/snice man pages which means you will break any subsequent compiles
with the flags enabled. Man pages not to be installed should still be
distributed.
2) The git version into Makefile.am breaks under certain conditions.
The easy break for this is:
touch aclocal.m4
make
We need this script added plus some dist hook magic that got left out.
If stream status is not checked at the end of execution below problem

Makes Debian patch makefile_watch_ncurses redundant.
watch was being linked to NCURSES_LIBS when it should of been
WATCH_NCURSES_LIBS which can be ncursesw with 8bit enabled.
The handling of the -c (count) option in free uses the standard string
handling and error utils. The program also checks for negative counts
and errors on these.
Some of the latest changes to Makefile.am files are missing.
This patch restores the LOCALEDIR variable, among others,
and dispenses with the include directives in the ps/ and top/
subdirectories since they're no longer needed.
The library used to be called libprocps but it was renamed to make sure
there was only one. However the formatting of the library SONAME has
changed so there cannot be any confusion.
libprocps makes it clear that its a library from this project and not a
set of functions directly on the filesystem.
This commit fixes also peculiar behavior of
$ slabtop -d 0
which did not make sense. The fix is to disallow anything else but
positive integers, which includes zero as is is not positive (or
negative) number.

The utility library is for functions which are shared in commands,
but that does not belong to libproc-ng. The first function is a

Previously the version of libproc always tracked the version of procps.
This doesn't work when other non-procps programs link to the library as
they are always playing catch up.
This change makes the library version independent of the procps version.
It will only be incremented when needed.
