The install target was using the wrong directory and would throw
some errors where a language couldn't translate man pages. This
one should be hopefully more robust.
Downloaded the updated translations of the binaries and the manpages
from translation project. Then fixed the typos that caused po4a to
fail, mainly errant spaces.
Using the newer po4a tool for manpage translations. Also removing
the manpage po file update from dist target because it should be
something the is explicitly done.
The git repository will hold the original man pages and the
po translation files. The distribution tarball will hold those
and the translated manpages. This means most people won't need po4a
as the distribution fill will have these translated manpages.
The previous Makefile rule would only put the first required file
into the pot file because it used $< Unfortunately, due to how
po4a tools work, its not just a simple matter of changing it to $^
and you're done, but needs a foreach loop to add -m to each manpage
file.
This is a temporary fix, after some more work looking into po4a the
unified tool (called po4a) will be used.
Beyond the copyrights, the single oops in the man page
was introduced in the commit which is referenced below

This patch will eliminate a bug which is unique to our
newlib branch. It's extremely rare and only happens if
a search ('L'/'&') is initiated during the period when
fields are currently being auto-sized (AUTOX_MODE on).
This bug surfaces as either all zero results for tasks
displayed or a segmentation fault, depending upon what
fields were activated. It is caused by the timing of a
call to the <pids> 'reset' function. When called after
a task refresh, but before do_key(), this bug appears.
So this patch just ensures that 'reset' will be called
after do_key() & before the tasks have been refreshed.

Under newlib, the only caller of the readproc routines
is that pids module. And in every case, the address of
some static proc_t structure has always been provided.
As a result, there is no need for the logic supporting
calloc() for a possible NULL pointer which was present
in both of those readproc() and readeither() routines.
Additionally, that pids module takes ownership of most
dynamically acquired 'str' plus 'strv' memory whenever
assigning to a results structure. So, henceforth under
the free_acquired() guy we will only free those string
fields which might exist when not explicitly selected.

@MarsChan correctly pointed out that the read() always returns 128
bytes, so skipping on >= 128 will always mean we skip. Their suggestion
was to remove the equality, but read will never go past 128 bytes so
I just removed that part of the check.

A recent issue (and merge request) reminded me of gaps
in top's alternate 'vim' navigation keys support. Some
xterm emulators do not pass the customary strings when
keys were used with the <Ctrl> and/or <Alt> modifiers.
While it was a known problem, this issue/merge request
prompted research into the root cause. As it turns out
the problem is traceable to an X resource known by the
name 'eightBitInput'. When 'true' (the default), a key
pressed in combination with <Alt> will not be preceded
by the <Esc> character. Rather, a single character was
presented (modified via an 'eightBitMeta' X resource).
The following approaches would eliminate this problem:
. start xterm thus: xterm -xrm '*eightBitInput: false'
. use: ~/.Xresources with 'Xterm*eightBitInput: false'
. build xterm with 'configure --enable-meta-sends-esc'
( apparently used for CentOS, Fedora, openSUSE, etc. )
. enable xterm's menu via 'configure --enable-toolbar'
( so the user can set the 'Meta Sends Escape' option )
Of course, none of the above steps is desirable from a
user's perspective. So, this patch will add additional
entries to the iokey function's tinfo_tab to represent
strings passed when the <Alt> key does not send <Esc>.
[ hopefully they'll be the same across all platforms ]
Lastly, this patch will also eliminate those redundant
<Atl> + '\', '/', '<' & '>' provisions, which now seem
like overkill and suffer from that same 'eightBitMeta'
xterm problem. And we might as well say goodbye to the
4 '<Alt> + arrow key' table entries (which do not seem
to currently work with any emulator which I can find).

This patch just implements an equivalent to the master
branch 'CPU_ZEROTICS' provision. However, the original
impetus for that earlier implementation was ultimately
attributed to a likely kernel anomaly since corrected.
As a result, in this newlib implementation we take the
opposite approach to the default behavior. There is no
adjustment to TIC_SUM_DELTA values if fewer ticks than
expected are recorded, unless the define is activated.
The commit shown below explains why the 'CPU_ZEROTICS'
define was retained in spite of the fix to the kernel.

Some parts of our newlib implementation are the result
of functions which have been propagated from module to
module. In particular, those 'cleanup_stacks' routines
are all similar & likely originated in the <pids> api.
In that interface there was a need to free dynamically
acquired memory before the result structure was reused
to satisfy subsequent 'get', 'select' or 'reap' calls.
This, in turn, led to a concept of 'dirty' stacks with
the need to call one of two 'cleanup_stack' functions.
None of the remaining interfaces deal with such memory
yet they each had their own 'cleanup_stack' functions.
Those functions were responsible for resetting each of
the result unions to zero, excluding any 'noop' items.
The bottom line is that for all interfaces, repetitive
calls would require iterating through the stack(s) two
separate times: once to 'cleanup' another to 'assign'.
With this commit we will reduce iterations to just the
'assign' routine. A reset to zero will be accomplished
in the 'extra' item set routine (which is the only one
actually requiring any reset). All other items will be
reinitialized automatically by a new current set value
or upon reallocation when an items compliment changes.
In the <pids> interface, any freeing of dynamic memory
could have been accomplished by adding that 'freefunc'
check to the 'assign' function. However, that requires
an Item_table test with every item. Instead, we'll now
satisfy such needs as the very first step in those set
functions responsible for dynamically acquired memory.
[ the <pids> api retains 2 'cleanup_stack' functions ]
[ to accommodate stack(s) 'reset' & to serve 'unref' ]
Lastly, all the 'itemize_stack' functions were tweaked
by eliminating an unnecessary initialization of result
unions. That objective was already accomplished by the
calloc() in a 'stacks_alloc' function or the remaining
'cleanup_stack' routine found in the <pids> interface.

These changes are an outgrowth of the research/testing
behind the previous commit. There is no commingling of
select/reap stacks in interfaces beyond the <pids> api
since there's no need to support any 'reset' function.
However, those <pids> changes prompted a review of all
interfaces offering that 'stacks_fetch' function, thus
revealing 2 instances of useless logic/wasted efforts.
Signed-off-by: Jim Warner <james.warner@comcast.net>
When the <pids> api was refactored in the commit shown
below, one objective was enabling the simultaneous use
of 'get' & 'select/reap' functions. Unlike other 'get'
functions, this <pids> 'get' acts as an iterator where
successive calls will return successive tasks/threads.
However, that goal wasn't quite met since a stack used
by 'get' was commingled with the 'select/reap' stacks.
Such commingling supported the 'reset' function, again
a provision which was unique to this <pids> interface.
Unfortunately, some poor assumptions in 'stacks_fetch'
produced a SEGV whenever 'reap/select' followed 'get'.
Thus, this patch addresses those issues and guarantees
such commingled stacks (extents) will be accommodated.

The commit referenced below addressed (some) anomalies
surrounding 'strv' pointers. However, there remained a
couple quirks involving a potential NULL return value.
Any NULL values returned from the old library readproc
guys would cause no real harm for newlib. But they did
produce the misleading "[ duplicate ENUM_ID ]" result.
The following all represent potential NULL results and
suggest shortcomings in testing of that earlier patch.
. kernel threads do not have cgroup, cmdline & environ
. even if present environ could require root to access
So, this patch reverts a portion of the earlier commit
and ensures when some vectored string is not available
a traditional dash ('-') is the 'strv' returned value.
