From ab48e6355dfb279ac70f05637e5533548eea773a Mon Sep 17 00:00:00 2001 From: Sergey Sharybin Date: Fri, 23 Mar 2018 14:32:18 +0100 Subject: Glog/gflags: Reduce amount of local modifications With better directory layout and more proper include statements we can avoid several local modifications, such as changing config.h for Windows Glog and the ones related on pass-through statements in logging headers in Glog. This commit also makes unused functions not-a-warning for external code. --- CMakeLists.txt | 3 +- extern/ceres/CMakeLists.txt | 12 +- extern/ceres/bundle.sh | 12 +- extern/gflags/README.blender | 5 - extern/gflags/src/gflags.cc | 6 +- extern/gflags/src/gflags_completions.cc | 2 - extern/glog/CMakeLists.txt | 14 +- extern/glog/README.blender | 2 + extern/glog/include/glog/log_severity.h | 92 ++ extern/glog/include/glog/logging.h | 1625 ++++++++++++++++++++++++++++++ extern/glog/include/glog/raw_logging.h | 185 ++++ extern/glog/include/glog/stl_logging.h | 220 +++++ extern/glog/include/glog/vlog_is_on.h | 129 +++ extern/glog/src/glog/log_severity.h | 92 -- extern/glog/src/glog/logging.h | 1632 ------------------------------- extern/glog/src/glog/raw_logging.h | 191 ---- extern/glog/src/glog/stl_logging.h | 226 ----- extern/glog/src/glog/vlog_is_on.h | 129 --- extern/glog/src/windows/glog/logging.h | 2 +- intern/cycles/util/util_logging.h | 1 + intern/libmv/CMakeLists.txt | 2 +- intern/libmv/bundle.sh | 2 +- 22 files changed, 2273 insertions(+), 2311 deletions(-) create mode 100644 extern/glog/include/glog/log_severity.h create mode 100644 extern/glog/include/glog/logging.h create mode 100644 extern/glog/include/glog/raw_logging.h create mode 100644 extern/glog/include/glog/stl_logging.h create mode 100644 extern/glog/include/glog/vlog_is_on.h delete mode 100644 extern/glog/src/glog/log_severity.h delete mode 100644 extern/glog/src/glog/logging.h delete mode 100644 extern/glog/src/glog/raw_logging.h delete mode 100644 extern/glog/src/glog/stl_logging.h delete mode 100644 extern/glog/src/glog/vlog_is_on.h diff --git a/CMakeLists.txt b/CMakeLists.txt index 9909544cd1a..212587d6d08 100644 --- a/CMakeLists.txt +++ b/CMakeLists.txt @@ -1294,7 +1294,7 @@ if(WITH_LIBMV OR WITH_GTESTS OR (WITH_CYCLES AND WITH_CYCLES_LOGGING)) if(WIN32) set(GLOG_INCLUDE_DIRS ${CMAKE_SOURCE_DIR}/extern/glog/src/windows) else() - set(GLOG_INCLUDE_DIRS ${CMAKE_SOURCE_DIR}/extern/glog/src) + set(GLOG_INCLUDE_DIRS ${CMAKE_SOURCE_DIR}/extern/glog/include) endif() endif() endif() @@ -1431,6 +1431,7 @@ if(CMAKE_COMPILER_IS_GNUCC) # flags to undo strict flags ADD_CHECK_C_COMPILER_FLAG(CC_REMOVE_STRICT_FLAGS C_WARN_NO_DEPRECATED_DECLARATIONS -Wno-deprecated-declarations) ADD_CHECK_C_COMPILER_FLAG(CC_REMOVE_STRICT_FLAGS C_WARN_NO_UNUSED_PARAMETER -Wno-unused-parameter) + ADD_CHECK_C_COMPILER_FLAG(CC_REMOVE_STRICT_FLAGS C_WARN_NO_UNUSED_FUNCTION -Wno-unused-function) if(CMAKE_COMPILER_IS_GNUCC AND (NOT "${CMAKE_C_COMPILER_VERSION}" VERSION_LESS "7.0")) ADD_CHECK_C_COMPILER_FLAG(CC_REMOVE_STRICT_FLAGS C_WARN_NO_IMPLICIT_FALLTHROUGH -Wno-implicit-fallthrough) diff --git a/extern/ceres/CMakeLists.txt b/extern/ceres/CMakeLists.txt index a6e9cd9c356..82695133a15 100644 --- a/extern/ceres/CMakeLists.txt +++ b/extern/ceres/CMakeLists.txt @@ -36,6 +36,8 @@ set(INC set(INC_SYS ${EIGEN3_INCLUDE_DIRS} + ${GFLAGS_INCLUDE_DIRS} + ${GLOG_INCLUDE_DIRS} ) set(SRC @@ -303,16 +305,6 @@ else() add_definitions(-DCERES_RESTRICT_SCHUR_SPECIALIZATION) endif() -if(WIN32) - list(APPEND INC - ../glog/src/windows - ) -else() - list(APPEND INC - ../glog/src - ) -endif() - add_definitions(${GFLAGS_DEFINES}) add_definitions(${GLOG_DEFINES}) add_definitions(${CERES_DEFINES}) diff --git a/extern/ceres/bundle.sh b/extern/ceres/bundle.sh index a4f703ac33d..1c9a2e729e5 100755 --- a/extern/ceres/bundle.sh +++ b/extern/ceres/bundle.sh @@ -129,6 +129,8 @@ set(INC set(INC_SYS \${EIGEN3_INCLUDE_DIRS} + \${GFLAGS_INCLUDE_DIRS} + \${GLOG_INCLUDE_DIRS} ) set(SRC @@ -145,16 +147,6 @@ else() add_definitions(-DCERES_RESTRICT_SCHUR_SPECIALIZATION) endif() -if(WIN32) - list(APPEND INC - ../glog/src/windows - ) -else() - list(APPEND INC - ../glog/src - ) -endif() - add_definitions(\${GFLAGS_DEFINES}) add_definitions(\${GLOG_DEFINES}) add_definitions(\${CERES_DEFINES}) diff --git a/extern/gflags/README.blender b/extern/gflags/README.blender index 68dba114329..c57f5ce53ca 100644 --- a/extern/gflags/README.blender +++ b/extern/gflags/README.blender @@ -17,10 +17,5 @@ Local modifications: - Applied some modifications from fork https://github.com/Nazg-Gul/gflags.git (see https://github.com/gflags/gflags/pull/129) -- Made `google::{anonymous}::FlagValue::ValueSize() const` inlined, so it does - not trigger strict compiler warning. - -- Did the same for CommandLineFlagParser::ValidateFlags(). - - Ifdef-ed __attribute((unused)) in gflags.h.

For instance, -// --vmodule=mapreduce=2,file=1,gfs*=3 --v=0 -// will cause: -// a. VLOG(2) and lower messages to be printed from mapreduce.{h,cc} -// b. VLOG(1) and lower messages to be printed from file.{h,cc} -// c. VLOG(3) and lower messages to be printed from files prefixed with "gfs" -// d. VLOG(0) and lower messages to be printed from elsewhere -// -// The wildcarding functionality shown by (c) supports both '*' (match -// 0 or more characters) and '?' (match any single character) wildcards. -// -// There's also VLOG_IS_ON(n) "verbose level" condition macro. To be used as -// -// if (VLOG_IS_ON(2)) { -// // do some logging preparation and logging -// // that can't be accomplished with just VLOG(2) << ...; -// } -// -// There are also VLOG_IF, VLOG_EVERY_N and VLOG_IF_EVERY_N "verbose level" -// condition macros for sample cases, when some extra computation and -// preparation for logs is not needed. -// VLOG_IF(1, (size > 1024)) -// << "I'm printed when size is more than 1024 and when you run the " -// "program with --v=1 or more"; -// VLOG_EVERY_N(1, 10) -// << "I'm printed every 10th occurrence, and when you run the program " -// "with --v=1 or more.

"; -// "Present occurence is " << google::COUNTER; -// -// The supported severity levels for macros that allow you to specify one -// are (in increasing order of severity) INFO, WARNING, ERROR, and FATAL. -// Note that messages of a given severity are logged not only in the -// logfile for that severity, but also in all logfiles of lower severity. -// E.g., a message of severity FATAL will be logged to the logfiles of -// severity FATAL, ERROR, WARNING, and INFO. -// -// There is also the special severity of DFATAL, which logs FATAL in -// debug mode, ERROR in normal mode. -// -// Very important: logging a message at the FATAL severity level causes -// the program to terminate (after the message is logged). -// -// Unless otherwise specified, logs will be written to the filename -// "...log..", followed -// by the date, time, and pid (you can't prevent the date, time, and pid -// from being in the filename). -// -// The logging code takes two flags: -// --v=# set the verbose level -// --logtostderr log all the messages to stderr instead of to logfiles - -// LOG LINE PREFIX FORMAT -// -// Log lines have this form: -// -// Lmmdd hh:mm:ss.uuuuuu threadid file:line] msg... -// -// where the fields are defined as follows: -// -// L A single character, representing the log level -// (eg 'I' for INFO) -// mm The month (zero padded; ie May is '05') -// dd The day (zero padded) -// hh:mm:ss.uuuuuu Time in hours, minutes and fractional seconds -// threadid The space-padded thread ID as returned by GetTID() -// (this matches the PID on Linux) -// file The file name -// line The line number -// msg The user-supplied message -// -// Example: -// -// I1103 11:57:31.739339 24395 google.cc:2341] Command line: ./some_prog -// I1103 11:57:31.739403 24395 google.cc:2342] Process id 24395 -// -// NOTE: although the microseconds are useful for comparing events on -// a single machine, clocks on different machines may not be well -// synchronized.
