Improvements and unification of logging library. This version works on all platforms: Linux, Windows and FreeBSD.
This is update to rework patch set. It adds several new features to the console log output. * Putting a timestamp on console output which is useful for analyzing performance of startup codes. Timestamp is optional and must be enabled on command line. * Displaying console output with colors. It uses the standard conventions used by many other Linux commands for colorized display. The default is to enable color if the console output is going to a terminal. But it can be always on or disabled by command line flag. This default was chosen based on what dmesg(1) command does. Color is used by many tools (vi, iproute2, git) because it is helpful; DPDK drivers and libraries print lots of not very useful messages. And having error messages highlighted in bold face helps. This might also get users to pay more attention to error messages. Many bug reports have earlier messages that are lost because there are so many info messages. * Add support for automatic detection of systemd journal protocol. If running as systemd service will get enhanced logging. * Use of syslog is optional and the meaning of the --syslog flag has changed. The default is *not* to use syslog if output is going to a terminal. Add myself as maintainer for log because by now have added more than previous authors. v22 - rebase, rearrange some code to stifle some checkpatch complaints and add release notes Stephen Hemminger (15): maintainers: add for log library windows: make getopt functions have const properties windows: add os shim for localtime_r eal: make eal_log_level_parse common eal: do not duplicate rte_init_alert() messages eal: change rte_exit() output to match rte_log() log: move handling of syslog facility out of eal eal: initialize log before everything else log: drop syslog support, and make code common log: add hook for printing log messages log: add timestamp option log: add optional support of syslog log: add support for systemd journal log: colorize log output doc: add release note about log library MAINTAINERS | 1 + app/test/test_eal_flags.c | 64 +++++- doc/guides/linux_gsg/linux_eal_parameters.rst | 27 --- doc/guides/prog_guide/log_lib.rst | 72 ++++++ doc/guides/rel_notes/release_24_11.rst | 14 ++ lib/eal/common/eal_common_debug.c | 11 +- lib/eal/common/eal_common_options.c | 136 +++++++----- lib/eal/common/eal_options.h | 7 + lib/eal/freebsd/eal.c | 64 ++---- lib/eal/linux/eal.c | 68 ++---- lib/eal/windows/eal.c | 49 +--- lib/eal/windows/getopt.c | 23 +- lib/eal/windows/include/getopt.h | 8 +- lib/eal/windows/include/rte_os_shim.h | 10 + lib/log/log.c | 83 ++++--- lib/log/log_color.c | 148 ++++++++++++ lib/log/log_freebsd.c | 12 - lib/log/log_internal.h | 28 ++- lib/log/log_journal.c | 200 +++++++++++++++++ lib/log/log_linux.c | 61 ----- lib/log/log_private.h | 33 +++ lib/log/log_stubs.c | 37 +++ lib/log/log_syslog.c | 88 ++++++++ lib/log/log_timestamp.c | 210 ++++++++++++++++++ lib/log/log_windows.c | 18 -- lib/log/meson.build | 13 +- lib/log/version.map | 5 +- 27 files changed, 1113 insertions(+), 377 deletions(-) create mode 100644 lib/log/log_color.c delete mode 100644 lib/log/log_freebsd.c create mode 100644 lib/log/log_journal.c delete mode 100644 lib/log/log_linux.c create mode 100644 lib/log/log_private.h create mode 100644 lib/log/log_stubs.c create mode 100644 lib/log/log_syslog.c create mode 100644 lib/log/log_timestamp.c delete mode 100644 lib/log/log_windows.c -- 2.45.2
