Generated with
sed -i 's|Copyright.*Andre Noll.*|SPDX-License-Identifier: GPL-2.0 */|g' *.c *.h

The GPLv2 line does not add any additional information, so drop
it. This leaves a single line of legalese text for most files, which
is about the amount of screen real estate it deserves.
This patch was created with the following script (plus some manual
fixups):
awk '{
if (NR <= 5) {
gs = gensub(/.*Copyright.* ([0-9]+).*Andre Noll.*/, "\\1", "g")
if (gs != $0)
year = gs
next
}
if (NR == 6 && year != "")
printf("/* Copyright (C) %s Andre Noll <maan@tuebingen.mpg.de>, see file COPYING. */\n", year)
print
}'

Only Mac OS (which is no longer supported) did not have it. Moreover,
on Linux we used to check whether one needs to link with -lrt to
obtain clock_gettime(), which is necessary for glibc versions 2.16
and earlier (released in 2012). All distributions should have moved
on to newer glibc versions by now, so let's get rid of the check.

Done with
files=$(git grep -l 'Copyright (C) [0-9]\{4\}\(-2014\)* Andre Noll')
sed --in-place= -e 's/Copyright (C) \([0-9]\{4\}\)-2014 Andre Noll/Copyright (C) \1 Andre Noll/1' $files
In previous years we ran a similar script to set the second year in
the range to the current year. This is kind of silly, so let's get
rid of this useless information.
This commit replaces "Copyright (C) A-B" by "Copyright (C) A" in
all file headers, i.e. only the first year (A) is left in. Accurate
information including time stamps for each change can be obtained
from the git history.

The mail server on systemlinux.org was down for more than a week
lately, so let's use an alternative official address. This commit
changes all maan@systemlinux.org addresses to maan@tuebingen.mpg.de.
Most .c and .h files contain the email address in the copyright header,
so they must all be patched. Three other files contain the address
for a different reason:
* README lists email and git, gitweb and home page URLs
* configure.ac needs it for configure -h
* version.c contains it for the -V option of all commands

This year, we're really on time. The changes in this patch were
created by the following silly script:
files=$(git grep -l 'Copyright (C) [0-9]\{4\}\(-2013\)* Andre Noll')
sed --in-place= -e 's/Copyright (C) \([0-9]\{4\}\)-2013 Andre Noll/Copyright (C) \1-2014 Andre Noll/1' $files
sed --in-place= -e 's/Copyright (C) 2013 Andre Noll/Copyright (C) 2013-2014 Andre Noll/1' $files

POSIX.1-2008 marks gettimeofday() as obsolete, so let's switch to
clock_gettime().
clock_gettime() operates on timespecs rather than on timevals like
gettimeofday() does. Since timevals are extensively used in all
parts of paraslash, and select() takes a timeval pointer as the
timeout parameter, it seems to be easiest to add a new wrapper,
clock_get_realtime(). It calls clock_gettime(), performs error
checking (all errors are treated fatal and abort the program), and
converts the result to a timeval.
Another difference between gettimeofday() and clock_gettime()
is that sys/time.h needs to be included for gettimeofday(), while
clock_gettime() is declared in time.h which gets included from para.h.
Hence we can remove the include statement for sys/time.h everywhere.
Programs which call clock_gettime need to be linked against librt on
glibc versions before 2.17 while BSD and newer glibc-based systems
have no such requirement. To make matters more interesting,
MacOS lacks clock_gettime() completely although this function conforms
to SUSv2 and POSIX.1-2001.
We'd like to avoid the unnecessary dependence on librt on systems that
have clock_gettime() in -lc, and we must fall back to gettimeofday()
on MacOS. Hence this commit also introduces a check in configure.ac
which determines whether clock_gettime() is available and, if it is,
whether -lrt is needed. Executables are only linked with -lrt if
configure found that this is necessary.

doxygen's \cond and \endcond commands treat the word after the
command as the name of the section which should be excluded from the
documentatation. So it is wrong to put an arbitrary comment there.
This fixes a couple of doxygen warnings about unknown loglevel defines
and makes these defines actually show up in the generated HTML.

Hey, this is earlier than last year :)

Fix some typos, make it return zero if both coefficients are zero.

Just use an uint64_t and compute everything in microseconds which even
simplifies the code a bit.
|
| | |
|
| | |
|
| |
|
|
| |
Also move compute_chunk_time() to time.c.

The old code contained an integer overflow which caused the mp3 audio
format handler to compute the chunk of large mp3 files incorrectly.
Moreover, the code was more complicated than necessary. So replace it
by a simple calculation which just transforms the given struct timeval
into its number of microseconds, does the division and transforms
the quotient back to a struct timeval.
Thanks to Gerrit Renker for pointing out the problem.

MAke doxygen happy again and add documentation for com_setatt().

These were introduced by the addition of -Wshadow.

MIN and MAX are already defined on MacOS.

Let's try if this works out.
