Switch to SPDX identifiers.

2026-03-17T22:45:43Z

Generated with sed -i 's|Copyright.*Andre Noll.*|SPDX-License-Identifier: GPL-2.0 */|g' *.c *.h followed by manually tweaking the result a bit. No license change intended.

Shorten copyright notice.

2017-09-22T14:35:22Z

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 , see file COPYING. */\n", year) print }'

build: Remove compatibility check for clock_gettime().

2017-01-04T22:13:22Z

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.

Update year in copyright headers.

2015-01-12T22:35:45Z

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.

doc: Change email address to maan@tuebingen.mpg.de

2014-08-18T20:38:53Z

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

Change copyright year to 2014.

2014-02-22T15:49:30Z

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

time.c: Make declarations match definitions.

Also fix some whitespace issues.

Replace gettimeofday() by clock_gettime().

2013-04-30T12:12:45Z

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.
