+/* This file includes Linux-specific support functions common to the
+ * coredumper and the thread lister; primarily, this is a collection
+ * of direct system calls, and a couple of symbols missing from
+ * standard header files.
+ * There are a few options that the including file can set to control
+ * the behavior of this file:
+ *
+ * SYS_CPLUSPLUS:
+ *   The entire header file will normally be wrapped in 'extern "C" { }",
+ *   making it suitable for compilation as both C and C++ source. If you
+ *   do not want to do this, you can set the SYS_CPLUSPLUS macro to inhibit
+ *   the wrapping. N.B. doing so will suppress inclusion of all prerequisite
+ *   system header files, too. It is the caller's responsibility to provide
+ *   the necessary definitions.
+ *
+ * SYS_ERRNO:
+ *   All system calls will update "errno" unless overriden by setting the
+ *   SYS_ERRNO macro prior to including this file. SYS_ERRNO should be
+ *   an l-value.
+ *
+ * SYS_INLINE:
+ *   New symbols will be defined "static inline", unless overridden by
+ *   the SYS_INLINE macro.
+ *
+ * SYS_LINUX_SYSCALL_SUPPORT_H
+ *   This macro is used to avoid multiple inclusions of this header file.
+ *   If you need to include this file more than once, make sure to
+ *   unset SYS_LINUX_SYSCALL_SUPPORT_H before each inclusion.
+ *
+ * SYS_PREFIX:
+ *   New system calls will have a prefix of "sys_" unless overridden by
+ *   the SYS_PREFIX macro. Valid values for this macro are [0..9] which
+ *   results in prefixes "sys[0..9]_". It is also possible to set this
+ *   macro to -1, which avoids all prefixes.
+ *
+ * This file defines a few internal symbols that all start with "LSS_".
+ * Do not access these symbols from outside this file. They are not part
+ * of the supported API.

+/* As glibc often provides subtly incompatible data structures (and implicit
+ * wrapper functions that convert them), we provide our own kernel data
+ * structures for use by the system calls.
+ * These structures have been developed by using Linux 2.6.23 headers for
+ * reference. Note though, we do not care about exact API compatibility
+ * with the kernel, and in fact the kernel often does not have a single
+ * API that works across architectures. Instead, we try to mimic the glibc
+ * API where reasonable, and only guarantee ABI compatibility with the
+ * kernel headers.
+ * Most notably, here are a few changes that were made to the structures
+ * defined by kernel headers:
+ *
+ * - we only define structures, but not symbolic names for kernel data
+ *   types. For the latter, we directly use the native C datatype
+ *   (i.e. "unsigned" instead of "mode_t").
+ * - in a few cases, it is possible to define identical structures for
+ *   both 32bit (e.g. i386) and 64bit (e.g. x86-64) platforms by
+ *   standardizing on the 64bit version of the data types. In particular,
+ *   this means that we use "unsigned" where the 32bit headers say
+ *   "unsigned long".
+ * - overall, we try to minimize the number of cases where we need to
+ *   conditionally define different structures.
+ * - the "struct kernel_sigaction" class of structures have been
+ *   modified to more closely mimic glibc's API by introducing an
+ *   anonymous union for the function pointer.
+ * - a small number of field names had to have an underscore appended to
+ *   them, because glibc defines a global macro by the same name.

+//    #include "foo.h"         // foo.h has a line "DECLARE_int32(start);"
+//
+//    DEFINE_int32(end, 1000, "The last record to read");

+// We describe many functions in this routine as being thread-hostile,

+//
+// thread-safe: it is safe for multiple threads to call this routine
+//   (or, when referring to a class, methods of this class)
+//   concurrently.
+// thread-hostile: it is not safe for multiple threads to call this
+//   routine (or methods of this class) concurrently.  In gflags,
+//   most thread-hostile routines are intended to be called early in,
+//   or even before, main() -- that is, before threads are spawned.
+// thread-compatible: it is safe for multiple threads to read from
+//   this variable (when applied to variables), or to call const
+//   methods of this class (when applied to classes), as long as no
+//   other thread is writing to the variable or calling non-const
+//   methods of this class.

+// Now come the command line flag declaration/definition macros that
+// will actually be used.  They're kind of hairy.  A major reason
+// for this is initialization: we want people to be able to access
+// variables in global constructors and have that not crash, even if
+// their global constructor runs before the global constructor here.
+// (Obviously, we can't guarantee the flags will have the correct
+// default value in that case, but at least accessing them is safe.)
+// The only way to do that is have flags point to a static buffer.
+// So we make one, using a union to ensure proper alignment, and
+// then use placement-new to actually set up the flag with the
+// correct default value.  In the same vein, we have to worry about
+// flag access in global destructors, so FlagRegisterer has to be
+// careful never to destroy the flag-values it constructs.
+//
+// Note that when we define a flag variable FLAGS_<name>, we also
+// preemptively define a junk variable, FLAGS_no<name>.  This is to
+// cause a link-time error if someone tries to define 2 flags with
+// names like "logging" and "nologging".  We do this because a bool
+// flag FLAG can be set from the command line to true with a "-FLAG"
+// argument, and to false with a "-noFLAG" argument, and so this can
+// potentially avert confusion.
+//
+// We also put flags into their own namespace.  It is purposefully
+// named in an opaque way that people should have trouble typing
+// directly.  The idea is that DEFINE puts the flag in the weird
+// namespace, and DECLARE imports the flag from there into the current
+// namespace.  The net result is to force people to use DECLARE to get
+// access to a flag, rather than saying "extern bool FLAGS_whatever;"
+// or some such instead.  We want this so we can put extra
+// functionality (like sanity-checking) in DECLARE if we want, and
+// make sure it is picked up everywhere.
+//
+// We also put the type of the variable in the namespace, so that
+// people can't DECLARE_int32 something that they DEFINE_bool'd
+// elsewhere.

+//
+// Implement helpful bash-style command line flag completions
+//
+// ** Functional API:
+// HandleCommandLineCompletions() should be called early during
+// program startup, but after command line flag code has been
+// initialized, such as the beginning of HandleCommandLineHelpFlags().
+// It checks the value of the flag --tab_completion_word.  If this
+// flag is empty, nothing happens here.  If it contains a string,
+// however, then HandleCommandLineCompletions() will hijack the
+// process, attempting to identify the intention behind this
+// completion.  Regardless of the outcome of this deduction, the
+// process will be terminated, similar to --helpshort flag
+// handling.
+//
+// ** Overview of Bash completions:
+// Bash can be told to programatically determine completions for the
+// current 'cursor word'.  It does this by (in this case) invoking a
+// command with some additional arguments identifying the command
+// being executed, the word being completed, and the previous word
+// (if any).  Bash then expects a sequence of output lines to be
+// printed to stdout.  If these lines all contain a common prefix
+// longer than the cursor word, bash will replace the cursor word
+// with that common prefix, and display nothing.  If there isn't such
+// a common prefix, bash will display the lines in pages using 'more'.
+//
+// ** Strategy taken for command line completions:
+// If we can deduce either the exact flag intended, or a common flag
+// prefix, we'll output exactly that.  Otherwise, if information
+// must be displayed to the user, we'll take the opportunity to add
+// some helpful information beyond just the flag name (specifically,
+// we'll include the default flag value and as much of the flag's
+// description as can fit on a single terminal line width, as specified
+// by the flag --tab_completion_columns).  Furthermore, we'll try to
+// make bash order the output such that the most useful or relevent
+// flags are the most likely to be shown at the top.
+//
+// ** Additional features:
+// To assist in finding that one really useful flag, substring matching
+// was implemented.  Before pressing a <TAB> to get completion for the
+// current word, you can append one or more '?' to the flag to do
+// substring matching.  Here's the semantics:
+//   --foo<TAB>     Show me all flags with names prefixed by 'foo'
+//   --foo?<TAB>    Show me all flags with 'foo' somewhere in the name
+//   --foo??<TAB>   Same as prior case, but also search in module
+//                  definition path for 'foo'
+//   --foo???<TAB>  Same as prior case, but also search in flag
+//                  descriptions for 'foo'
+// Finally, we'll trim the output to a relatively small number of
+// flags to keep bash quiet about the verbosity of output.  If one
+// really wanted to see all possible matches, appending a '+' to the
+// search word will force the exhaustive list of matches to be printed.
+//
+// ** How to have bash accept completions from a binary:
+// Bash requires that it be informed about each command that programmatic
+// completion should be enabled for.  Example addition to a .bashrc
+// file would be (your path to gflags_completions.sh file may differ):
+
+/*
+$ complete -o bashdefault -o default -o nospace -C                        \
+ '/usr/local/bin/gflags_completions.sh --tab_completion_columns $COLUMNS' \
+  time  env  binary_name  another_binary  [...]
+*/
+
+// This would allow the following to work:
+//   $ /path/to/binary_name --vmodule<TAB>
+// Or:
+//   $ ./bin/path/another_binary --gfs_u<TAB>
+// (etc)
+//
+// Sadly, it appears that bash gives no easy way to force this behavior for
+// all commands.  That's where the "time" in the above example comes in.
+// If you haven't specifically added a command to the list of completion
+// supported commands, you can still get completions by prefixing the
+// entire command with "env".
+//   $ env /some/brand/new/binary --vmod<TAB>
+// Assuming that "binary" is a newly compiled binary, this should still
+// produce the expected completion output.

+// Make a bunch of macros for logging.  The way to log things is to stream
+// things to LOG(<a particular severity level>).  E.g.,
+//
+//   LOG(INFO) << "Found " << num_cookies << " cookies";
+//
+// You can capture log messages in a string, rather than reporting them
+// immediately:
+//
+//   vector<string> errors;
+//   LOG_STRING(ERROR, &errors) << "Couldn't parse cookie #" << cookie_num;
+//
+// This pushes back the new error onto 'errors'; if given a NULL pointer,
+// it reports the error via LOG(ERROR).
+//
+// You can also do conditional logging:
+//
+//   LOG_IF(INFO, num_cookies > 10) << "Got lots of cookies";
+//
+// You can also do occasional logging (log every n'th occurrence of an
+// event):
+//
+//   LOG_EVERY_N(INFO, 10) << "Got the " << COUNTER << "th cookie";
+//
+// The above will cause log messages to be output on the 1st, 11th, 21st, ...
+// times it is executed.  Note that the special COUNTER value is used to
+// identify which repetition is happening.
+//
+// You can also do occasional conditional logging (log every n'th
+// occurrence of an event, when condition is satisfied):
+//
+//   LOG_IF_EVERY_N(INFO, (size > 1024), 10) << "Got the " << COUNTER
+//                                           << "th big cookie";
+//
+// You can log messages the first N times your code executes a line. E.g.
+//
+//   LOG_FIRST_N(INFO, 20) << "Got the " << COUNTER << "th cookie";
+//
+// Outputs log messages for the first 20 times it is executed.
+//
+// Analogous SYSLOG, SYSLOG_IF, and SYSLOG_EVERY_N macros are available.
+// These log to syslog as well as to the normal logs.  If you use these at
+// all, you need to be aware that syslog can drastically reduce performance,
+// especially if it is configured for remote logging!  Don't use these
+// unless you fully understand this and have a concrete need to use them.
+// Even then, try to minimize your use of them.
+//
+// There are also "debug mode" logging macros like the ones above:
+//
+//   DLOG(INFO) << "Found cookies";
+//
+//   DLOG_IF(INFO, num_cookies > 10) << "Got lots of cookies";
+//
+//   DLOG_EVERY_N(INFO, 10) << "Got the " << COUNTER << "th cookie";
+//
+// All "debug mode" logging is compiled away to nothing for non-debug mode
+// compiles.
+//
+// We also have
+//
+//   LOG_ASSERT(assertion);
+//   DLOG_ASSERT(assertion);
+//
+// which is syntactic sugar for {,D}LOG_IF(FATAL, assert fails) << assertion;
+//
+// There are "verbose level" logging macros.  They look like
+//
+//   VLOG(1) << "I'm printed when you run the program with --v=1 or more";
+//   VLOG(2) << "I'm printed when you run the program with --v=2 or more";
+//
+// These always log at the INFO log level (when they log at all).
+// The verbose logging can also be turned on module-by-module.  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 " << COUNTER;
+//   VLOG_IF_EVERY_N(1, (size > 1024), 10)
+//      << "I'm printed on every 10th occurence of case when size is more "
+//         " than 1024, when you run the program with --v=1 or more. ";
+//         "Present occurence is " << 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
+// "<program name>.<hostname>.<user name>.log.<severity level>.", 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

+// conditional logging.
+//
+// It's used by VLOG and VLOG_IF in logging.h
+// and by RAW_VLOG in raw_logging.h to trigger the logging.
+//
+// It can also be used directly e.g. like this:
+//   if (VLOG_IS_ON(2)) {
+//     // do some logging preparation and logging
+//     // that can't be accomplished e.g. via just VLOG(2) << ...;
+//   }
+//
+// The truth value that VLOG_IS_ON(level) returns is determined by 
+// the three verbosity level flags:
+//   --v=<n>  Gives the default maximal active V-logging level;
+//            0 is the default.
+//            Normally positive values are used for V-logging levels.
+//   --vmodule=<str>  Gives the per-module maximal V-logging levels to override
+//                    the value given by --v.
+//                    E.g. "my_module=2,foo*=3" would change the logging level
+//                    for all code in source files "my_module.*" and "foo*.*"
+//                    ("-inl" suffixes are also disregarded for this matching).
+//
+// SetVLOGLevel helper function is provided to do limited dynamic control over
+// V-logging by overriding the per-module settings given via --vmodule flag.
+//
