Analogous to the way it is done in xlat/gen.sh.
* maint/update_copyright_years.sh (MAX_JOBS): New variable, initialize
it to double the CPU count.
<while [ -n "${1:-}" ]; do case "$1" in>: Add -j option parsing.
(jobs, pids): New variables.
<git ls-files -- "$@" | grep -vFx "$IGNORED_FILES" | while read f; do>:
Execute process_file in background, count background jobs and wait
if there are too many.
Implement various features in order to make it suitable for the
generation of the CREDITS file:
- add an option for including contributor e-mail;
- add an option to read additional list of contributors from stdin;
- add shorthand for referring to the initial commit of the branch;
- document all of the above in a help message.
* maint/gen-contributors-list.sh (print_help): New function.
(script): Rename to SCRIPT.
(SCRIPT_NORM_EMAILS, MATCH_OUT, OUT_EMAILS, OUT_NO_EMAILS, read_stdin,
include_email): New variables.
Add parsing of options, rewrite input processing.
Unfortunately, he wasn't mentioned in the message of the commit
v4.19-68-g48cb633, so let's fix that omission.

This commit implements the following changes:
- increases the number of concurrent jobs to twice the CPU count;
- creates a circular buffer, so instead of running multiple jobs
at once, the generator tries to keep about the same number of jobs
being run concurrently;
- runs gen_git and gen_make concurrently in order to squeeze in
one more bit of concurrency.
With my deeply scientific measurements, this approach achieves
up to 15% speedup with dash and about 30-40% with bash as /bin/sh
on a 4-core machine.
* xlat/gen.sh (main): Declare pids local variable, append pid of every
run job to it; increase the limit of jobs to ncpus * 2; when the limit
is reached, wait for the first pid in pids instead of resetting jobs
to zero and waiting for all the run jobs; put gen_git and gen_make
into background.
Starting with commit v4.17-5-gf83b49b strace is expected
to forward the signal mask to tracees unchanged.
* tests/check_sigblock.c: New file.
* tests/set_sigblock.c: Likewise.
* tests/sigblock.test: New test.
* tests/.gitignore: Add check_sigblock and set_sigblock.
* tests/Makefile.am (check_PROGRAMS): Likewise.
(MISC_TESTS): Add sigblock.test.
Starting with commit v4.17-8-ge97a66f strace is expected
to forward the signal disposition to tracees unchanged.
* tests/check_sigign.c: New file.
* tests/list_sigaction_signum.c: Likewise.
* tests/set_sigign.c: Likewise.
* tests/sigign.test: New test.
* tests/.gitignore: Add check_sigign, list_sigaction_signum,
and set_sigign.
* tests/Makefile.am (check_PROGRAMS): Likewise.
(MISC_TESTS): Add sigign.test.
Kernel commit v4.14-rc1~162^2~8 refactored futex implementation and
introduced checks for invalid shift sizes. Accommodate this change
by allowing EINVAL in the corresponding futex checks.
* tests/futex.c (CHECK_FUTEX_GENERIC): Reset errno before the syscall.
(main) <wake_ops>: Add err2 field, describe err/err2 fields.
Add EINVAL as a possible errno to the checks that contain invalid
shift values.
Update return value check so it checks that values are strictly
as expected.
Closes: https://github.com/strace/strace/pull/16
Workaround musl >= 1.1.17 ability to use AT_EXECFN during
program_invocation_name initialization.
* tests/options-syntax.test: Check for two valid variants
of "zeroargc strace" expected output.
Refactor decode_nlmsg_flags to make it family-specific, just like
decode_nlmsg_type and decode_payload.
* netlink.c (decode_nlmsg_flags_crypto, decode_nlmsg_flags_route,
decode_nlmsg_flags_sock_diag, decode_nlmsg_flags_xfrm): New functions.
(nlmsg_flags_decoder_t): New typedef.
(nlmsg_flags): New array.
(decode_nlmsg_flags): Use it.
When using linux kernel headers without commit v4.5-rc1~128^2~115^2~22
("netfilter: fix include files for compilation"), both <linux/ip.h>
and <linux/tcp.h> have to be included before <linux/netfilter/xt_osf.h>.
* configure.ac (AC_CHECK_HEADERS): Include <linux/ip.h>
and <linux/tcp.h> when checking for linux/netfilter/xt_osf.h header.
* tests/nfnetlink_osf.c: Include <linux/ip.h> and <linux/tcp.h>
before <linux/netfilter/xt_osf.h>.
