/**
- * Implementations of ProcessHandleImpl functions that are common to all
- * Unix variants:
- * - waitForProcessExit0(pid, reap)
- * - getCurrentPid0()
- * - destroy0(pid, force)
+ * This file contains the implementation of the native ProcessHandleImpl
+ * functions which are common to all Unix variants.
+ *
+ * The currently supported Unix variants are Solaris, Linux, MaxOS X and AIX.
+ * The various similarities and differences between these systems make it hard
+ * to find a clear boundary between platform specific and shared code.
+ *
+ * In order to ease code sharing between the platforms while still keeping the
+ * code as clean as possible (i.e. free of preprocessor macros) we use the
+ * following source code layout (remember that ProcessHandleImpl_unix.c will
+ * be compiled on EVERY Unix platform while ProcessHandleImpl_<os>.c will be
+ * only compiled on the specific OS):
+ *
+ * - all the JNI wrappers for the ProcessHandleImpl functions go into this file
+ * - if their implementation is common on ALL the supported Unix platforms it
+ * goes right into the JNI wrappers
+ * - if the whole function or substantial parts of it are platform dependent,
+ * the implementation goes into os_<function_name> functions in
+ * ProcessHandleImpl_<os>.c
+ * - if at least two platforms implement an os_<function_name> function in the
+ * same way, this implementation is factored out into unix_<function_name>,
+ * placed into this file and called from the corresponding os_<function_name>
+ * function.
+ * - For convenience, all the os_ and unix_ functions are declared in
+ * ProcessHandleImpl_unix.h which is included into every
+ * ProcessHandleImpl_<os>.c file.
+ *
+ * Example 1:
+ * ----------
+ * The implementation of Java_java_lang_ProcessHandleImpl_initNative()
+ * is the same on all platforms except on Linux where it initilizes one
+ * additional field. So we place the implementation right into
+ * Java_java_lang_ProcessHandleImpl_initNative() but add call to
+ * os_init() at the end of the function which is empty on all platforms
+ * except Linux where it performs the additionally initializations.
+ *
+ * Example 2:
+ * ----------
+ * The implementation of Java_java_lang_ProcessHandleImpl_00024Info_info0 is the
+ * same on Solaris and AIX but different on Linux and MacOSX. We therefore simply
+ * call the helpers os_getParentPidAndTimings() and os_getCmdlineAndUserInfo().
+ * The Linux and MaxOS X versions of these functions (in the corresponding files
+ * ProcessHandleImpl_linux.c and ProcessHandleImpl_macosx.c) directly contain
+ * the platform specific implementations while the Solaris and AIX
+ * implementations simply call back to unix_getParentPidAndTimings() and
+ * unix_getCmdlineAndUserInfo() which are implemented right in this file.
+ *
+ * The term "same implementation" is still a question of interpretation. It my
+ * be acceptable to have a few ifdef'ed lines if that allows the sharing of a
+ * huge function. On the other hand, if the platform specific code in a shared
+ * function grows over a certain limit, it may be better to refactor that
+ * functionality into corresponding, platform-specific os_ functions.

-------
-
-Design and Implementation:
-
- * The Tracker Class (Tracker.java & hprof_tracker.c)
- It was added to the sun.tools.hprof.Tracker in JDK 5.0 FCS, then
- moved to a package that didn't cause classload errors due to
- the security manager not liking the sun.* package name.
- 5091195 detected that this class needs to be in com.sun.demo.jvmti.hprof.
- The BCI code will call these static methods, which will in turn
- (if engaged) call matching native methods in the hprof library,
- with the additional current Thread argument (Thread.currentThread()).
- Doing the currentThread call on the Java side was necessary due
- to the difficulty of getting the current thread while inside one
- of these Tracker native methods. This class lives in rt.jar.
-
- * Byte Code Instrumentation (BCI)
- Using the ClassFileLoadHook feature and a C language
- implementation of a byte code injection transformer, the following
- bytecodes get injections:
- - On entry to the java.lang.Object <init> method,
- a invokestatic call to
- Tracker.ObjectInit(this);
- is injected.
- - On any newarray type opcode, immediately following it,
- the array object is duplicated on the stack and an
- invokestatic call to
- Tracker.NewArray(obj);
- is injected.
- - On entry to all methods, a invokestatic call to
- Tracker.CallSite(cnum,mnum);
- is injected. The hprof agent can map the two integers
- (cnum,mnum) to a method in a class. This is the BCI based
- "method entry" event.
- - On return from any method (any return opcode),
- a invokestatic call to
- Tracker.ReturnSite(cnum,mnum);
- is injected.
- All classes found via ClassFileLoadHook are injected with the
- exception of some system class methods "<init>" and "finalize"
- whose length is 1 and system class methods with name "<clinit>",
- and also java.lang.Thread.currentThread() which is used in the
- class Tracker (preventing nasty recursion issue).
- System classes are currently defined as any class seen by the
- ClassFileLoadHook prior to VM_INIT. This does mean that
- objects created in the system classes inside <clinit> might not
- get tracked initially.
- See the java_crw_demo source and documentation for more info.
- The injections are based on what the hprof options
- are requesting, e.g. if heap=sites or heap=all is requested, the
- newarray and Object.<init> method injections happen.
- If cpu=times is requested, all methods get their entries and
- returns tracked. Options like cpu=samples or monitor=y
- do not require BCI.
-
- * BCI Allocation Tags (hprof_tag.c)
- The current jlong tag being used on allocated objects
- is an ObjectIndex, or an index into the object table inside
- the hprof code. Depending on whether heap=sites or heap=dump
- was asked for, these ObjectIndex's might represent unique
- objects, or unique allocation sites for types of objects.
- The heap=dump option requires considerable more space
- due to the one jobject per ObjectIndex mapping.
-
- * BCI Performance
- The cpu=times seems to have the most negative affect on
- performance, this could be improved by not having the
- Tracker class methods call native code directly, but accumulate
- the data in a file or memory somehow and letting it buffer down
- to the agent. The cpu=samples is probably a better way to
- measure cpu usage, varying the interval as needed.
- The heap=dump seems to use memory like crazy, but that's
- partially the way it has always been.

-/* **************************************************************************
- *
- * Set of malloc/realloc/calloc/strdup/free replacement macros that
- * insert some extra words around each allocation for debugging purposes
- * and also attempt to detect invalid uses of the malloc heap through
- * various tricks like inserting clobber words at the head and tail of
- * the user's area, delayed free() calls, and setting the memory to
- * a fixed pattern on allocation and when freed. The allocations also
- * can include warrants so that when an area is clobbered, this
- * package can report where the allocation took place.
- * The macros included are:
- * malloc(size)
- * realloc(ptr,size)
- * calloc(nelem,elsize)
- * strdup(s1)
- * free(ptr)
- * malloc_police() <--- Not a system function
- * The above macros match the standard behavior of the system functions.
- *
- * They should be used through the include file "debug_malloc.h".
- *
- * IMPORTANT: All source files that call any of these macros
- * should include debug_malloc.h. This package will
- * not work if the memory isn't allocated and freed
- * by the macros in debug_malloc.h. The important issue
- * is that any malloc() from debug_malloc.h must be
- * freed by the free() in debug_malloc.h.
- *
- * The macros in debug_malloc.h will override the normal use of
- * malloc, realloc, calloc, strdup, and free with the functions below.
- *
- * These functions include:
- * void *debug_malloc(size_t, void*, int);
- * void *debug_realloc(void*, size_t, void*, int);
- * void *debug_calloc(size_t, size_t, void*, int);
- * void debug_free(void *, void*, int);
- *
- * In addition the function debug_malloc_police() can be called to
- * tell you what memory has not been freed.
- * void debug_malloc_police(void*, int);
- * The function debug_malloc_police() is available through the macro
- * malloc_police(). Normally you would want to call this at exit()
- * time to find out what memory is still allocated.
- *
- * The variable malloc_watch determines if the warrants are generated.
- * warrants are structures that include the filename and line number
- * of the caller who allocated the memory. This structure is stored
- * at the tail of the malloc space, which is allocated large enough
- * to hold some clobber words at the head and tail, the user's request
- * and the warrant record (if malloc_watch is non-zero).
- *
- * The macro LEFT_OVER_CHAR is what the trailing bytes of an allocation
- * are set to (when the allocation is not a multiple of 8) on allocation.
- * At free(0 time, these bytes are double checked to make sure they were
- * not clobbered. To remove this feature #undef LEFT_OVER_CHAR.
- *
- * The memory freed will have the FREED_CHAR put into it. To remove this
- * feature #undef FREED_CHAR.
- *
- * The memory allocated (not calloc'd) will have the ALLOC_CHAR put into it
- * at the time of allocation. To remove this feature #undef ALLOC_CHAR.
- *
- * The macro MAX_FREE_DELAY_COUNT controls how many free blocks will
- * be kept around before being freed. This creates a delayed affect
- * so that free space that gets clobbered just might get detected.
- * The free() call will immediately set the user space to the FREED_CHAR,
- * leaving the clobber words and warrant in place (making sure they
- * haven't been clobbered). Then the free() pointer is added to a
- * queue of MAX_FREE_DELAY_COUNT long, and if the queue was full, the
- * oldest free()'d memory is actually freed, getting it's entire
- * memory length set to the FREED_CHAR.
- *
- * WARNING: This can significantly slow down an application, depending
- * on how many allocations are made. Also the additional memory
- * needed for the clobber words and the warrants can be significant
- * again, depending on how many allocations are made.
- * In addition, the delayed free calls can create situations
- * where you might run out of memory prematurely.

- * The hprof agent has many forms of output:

- * format=b gdata->output_format=='b'
- * Binary format. Defined below. This is used by HAT.
- * This is NOT the same format as emitted by JVMPI.
- *
- * format=a gdata->output_format=='a'
- * Ascii format. Not exactly an ascii representation of the binary format.
- *
- * And many forms of dumps:
- *
- * heap=dump
- * A large dump that in this implementation is written to a separate
- * file first before being placed in the output file. Several reasons,
- * the binary form needs a byte count of the length in the header, and
- * references in this dump to other items need to be emitted first.
- * So it's two pass, or use a temp file and copy.
- * heap=sites
- * Dumps the sites in the order of most allocations.
- * cpu=samples
- * Dumps the traces in order of most hits
- * cpu=times
- * Dumps the traces in the order of most time spent there.
- * cpu=old (format=a only)
- * Dumps out an older form of cpu output (old -prof format)
- * monitor=y (format=a only)
- * Dumps out a list of monitors in order of most contended.
- *
- * This file also includes a binary format check function that will read
- * back in the hprof binary format and verify the syntax looks correct.
- *
- * WARNING: Besides the comments below, there is little format spec on this,
- * however see:

-/* Object table. */

-/*
- * An Object is unique by it's allocation site (SiteIndex), it's size,
- * it's kind, and it's serial number. Normally only the serial number
- * would have been necessary for heap=dump, and these other items
- * could have been moved to the ObjectInfo. An optimization left
- * to the reader. Lookups are not normally done on ObjectIndex's
- * anyway because we typically know when to create them.
- * Objects that have been tagged, are tagged with an ObjectIndex,
- * Objects that are not tagged need a ObjectIndex, a lookup when
- * heap=sites, and a new one when heap=dump.
- * Objects that are freed, need the tag converted to an ObjectIndex,
- * so they can be freed, but only when heap=dump.
- * The thread serial number is for the thread associated with this
- * object. If the object is a Thread object, it should be the serial
- * number for that thread. The ThreadStart event is responsible
- * for making sure the thread serial number is correct, but between the
- * initial allocation of a Thread object and it's ThreadStart event
- * the thread serial number could be for the thread that allocated
- * the Thread object.
- *
- * This will likely be the largest table when using heap=dump, when
- * there is one table entry per object.
- *
- * ObjectIndex entries differ between heap=dump and heap=sites.
- * With heap=sites, each ObjectIndex represents a unique site, size,
- * and kind of object, so many jobject's will map to a single ObjectIndex.
- * With heap=dump, every ObjectIndex maps to a unique jobject.
- *
- * During processing of a heap dump, the references for the object
- * this ObjectIndex represents is assigned to the references field
- * of the ObjectInfo as a linked list. (see hprof_references.c).
- * Once all the refernces are attached, they are processed into the
- * appropriate hprof dump information.
- *
- * The references field is set and cleared as many times as the heap
- * is dumped, as is the reference table.

- * heap (see hprof_site.c).
- *
- * Most of these table entries have no Key, but the key is used to store
- * the primitive array and primitive field jvalue. None of these entries
- * are ever looked up, there will be no hash table, use of the
- * LookupTable was just an easy way to handle a unbounded table of
- * entries. The object table (see hprof_object.c) will completely
- * free this reference table after each heap dump or after processing the
- * references and primitive data.
- *
- * The hprof format required this accumulation of all heap iteration
- * references and primitive data from objects in order to compose an
- * hprof records for it.
- *
- * This file contains detailed understandings of how an hprof CLASS
- * and INSTANCE dump is constructed, most of this is derived from the
- * original hprof code, but some has been derived by reading the HAT
- * code that accepts this format.

- * Each table has a unique lock, all accesses are protected.
- *
- * Table elements are identified with a 32bit unsigned int.
- * (Also see HARE trick below, which makes the TableIndex unique per table).
- *
- * Each element has a key (N bytes) and possible additional info.
- *
- * Two elements with the same key should be the same element.
- *
- * The storage for the Key and Info cannot move, the table itself can.
- *
- * The hash table will only be allocated if we have keys, and will resize
- * when the table needs to resize. The hash buckets just provide the
- * reference to the first TableIndex in the hash bucket, the next
- * field of the TableElement takes you to the next item in the hash
- * bucket. Lookups will drift the looked up item to the head of the
- * list.
- *
- * The full 32bit hashcode and key length is saved for comparisons, the
- * last thing done is the actual comparison of the Key contents with
- * keys_equal().
- *
- * Freed elements (not many tables actually free items) are managed with
- * a bit vector and a low index where a freed element might be found.
- * Bytes are inspected until a non-zero byte indicates a freed bit is
- * set. A count of freed elements is also kept.

-Header for -agentlib:hprof (or -Xrunhprof) ASCII Output (JDK 5.0 JVMTI based)
-
-WARNING! This file format is under development, and is subject to
-change without notice.
-
-This file contains the following types of records:
-
-THREAD START
-THREAD END mark the lifetime of Java threads
-
-TRACE represents a Java stack trace. Each trace consists
- of a series of stack frames. Other records refer to
- TRACEs to identify (1) where object allocations have
- taken place, (2) the frames in which GC roots were
- found, and (3) frequently executed methods.
-
-HEAP DUMP is a complete snapshot of all live objects in the Java
- heap. Following distinctions are made:
-
- ROOT root set as determined by GC
- CLS classes
- OBJ instances
- ARR arrays
-
-SITES is a sorted list of allocation sites. This identifies
- the most heavily allocated object types, and the TRACE
- at which those allocations occurred.
-
-CPU SAMPLES is a statistical profile of program execution. The VM
- periodically samples all running threads, and assigns
- a quantum to active TRACEs in those threads. Entries
- in this record are TRACEs ranked by the percentage of
- total quanta they consumed; top-ranked TRACEs are
- typically hot spots in the program.
-
-CPU TIME is a profile of program execution obtained by measuring
- the time spent in individual methods (excluding the time
- spent in callees), as well as by counting the number of
- times each method is called. Entries in this record are
- TRACEs ranked by the percentage of total CPU time. The
- "count" field indicates the number of times each TRACE
- is invoked.
-
-MONITOR TIME is a profile of monitor contention obtained by measuring
- the time spent by a thread waiting to enter a monitor.
- Entries in this record are TRACEs ranked by the percentage
- of total monitor contention time and a brief description
- of the monitor. The "count" field indicates the number of
- times the monitor was contended at that TRACE.
-
-MONITOR DUMP is a complete snapshot of all the monitors and threads in
- the System.
-
-HEAP DUMP, SITES, CPU SAMPLES|TIME and MONITOR DUMP|TIME records are generated
-at program exit. They can also be obtained during program execution by typing
-Ctrl-\ (on Solaris) or by typing Ctrl-Break (on Win32).

-<h2><a name="mozTocId550204" class="mozTocH2"></a>Overview</h2>
-<p>This document describes the JVM TI Agent HPROF delivered in
-the Java Development Kit (JDK). It is intended as demonstration code
-for JVM TI, and as a functional
-replacement for the older HPROF JVMPI Agent delivered in past releases.<br>
-</p>
-Previous 1.4 and earlier releases of the JDK contained an HPROF
-agent built on the experimental JVMPI.
-The newer JVM TI replaces both JVMDI and JVMPI.
-<p><span style="font-weight: bold;">Note</span>: Differences between
-this HPROF implementation and the older JVMPI based HPROF are marked in
-<span style="font-style: italic; color: rgb(255, 0, 0);">RED ITALICS</span>
-throughout this document.<br>
-</p>
-<br>
-<h2><a name="mozTocId634758" class="mozTocH3"></a>Start-up</h2>
-<p>HPROF is a simple profiler agent shipped with the JDK. It is
-a dynamically-linked
-library that interacts with the JVM TI and
-writes out profiling
-information either to a file or to a socket in ascii or binary format.
-This information can
-be further processed by a profiler front-end tool.</p>
-<p>It is capable of presenting CPU usage, heap allocation statistics
-and monitor contention
-profiles. In addition it can also report complete heap dumps and states
-of all the monitors and threads in the Java virtual machine.
-</p>
-<p>HPROF can be invoked by:
-</p>
-<pre>java -<span style="font-weight: bold;">agentlib:</span><b>hprof</b> ToBeProfiledClass</pre>
-Depending on the type of profiling requested, HPROF instructs the
-virtual machine to send it the relevant JVM TI events and processes
-the event data into profiling information. For example, the following
-command obtains the heap allocation profile:
-<pre>java -agentlib:hprof=heap=sites ToBeProfiledClass</pre>
-Following is the complete list of options that can passed to hprof :
-<blockquote>
- <pre>java -agentlib:hprof=help<br><br> HPROF: Heap and CPU Profiling Agent (JVMTI Demonstration Code)<br><br>hprof usage: java -agentlib:hprof=[help]|[<option>=<value>, ...]<br><br>Option Name and Value Description Default<br>--------------------- ----------- -------<br>heap=dump|sites|all heap profiling all<br>cpu=samples|times|old CPU usage off<br>monitor=y|n monitor contention n<br>format=a|b text(txt) or binary output a<br>file=<file> write data to file java.hprof[{.txt}]<br>net=<host>:<port> send data over a socket off<br>depth=<size> stack trace depth 4<br>interval=<ms> sample interval in ms 10<br>cutoff=<value> output cutoff point 0.0001<br>lineno=y|n line number in traces? y<br>thread=y|n thread in traces? n<br>doe=y|n dump on exit? y<br>msa=y|n Solaris micro state accounting n<br>force=y|n force output to <file> y<br>verbose=y|n print messages about dumps y<br><br>Obsolete Options<br>----------------<br>gc_okay=y|n<br><br>Examples<br>--------<br> - Get sample cpu information every 20 millisec, with a stack depth of 3:<br> java -agentlib:hprof=cpu=samples,interval=20,depth=3 classname<br> - Get heap usage information based on the allocation sites:<br> java -agentlib:hprof=heap=sites classname<br><br>Notes<br>-----<br> - The option format=b cannot be used with monitor=y.<br> - The option format=b cannot be used with cpu=old|times.<br> - Use of the -Xrunhprof interface can still be used, e.g.<br> java -Xrunhprof:[help]|[<option>=<value>, ...]<br> will behave exactly the same as:<br> java -agentlib:hprof=[help]|[<option>=<value>, ...]<br><br>Warnings<br>--------<br> - This is demonstration code for the JVMTI interface and use of BCI,<br> it is not an official product or formal part of the JDK.<br> - The -Xrunhprof interface will be removed in a future release.<br> - The option format=b is considered experimental, this format may change<br> in a future release.<br></pre>
-</blockquote>
-<p>By default, heap profiling information (sites and dump) is written
-out
-to java.hprof.txt (ascii).
-The monitor=y|n option has proven to be problematic and may be replaced
-with something more useful.<br>
-</p>
-<p>The output in most cases will contain ID's for traces, threads,
-objects, etc. Each type of ID will typically start with a
-different number than the other ID's, e.g. traces might start with
-300000.<br>
-</p>
-<p><span style="font-weight: bold;">Note</span>: <span

-<h2><a name="mozTocId708821" class="mozTocH4"></a>Heap Allocation
-Profiles (heap=sites)<br>

-Following is the heap allocation profile generated by running the Java
-compiler
-(<code>javac</code>) on a set of input files. Only parts of the
-profiler output are shown here.

-A crucial piece of information in heap profile is the amount of
-allocation that occurs
-in various parts of the program. The <code>SITES</code> record above
-tells us that 44.13% of the total space was allocated for
-java.util.zip.ZipEntry objects. Note that the amount of live data is
-only a fraction
-of the total allocation that has occurred at a given site; the rest has
-been garbage collected.
-<p>A good way to relate allocation sites to the source code is to
-record
-the dynamic stack traces that led to the heap allocation. Following is
-another part of the profiler output that illustrates the stack traces
-referred to by the four allocation sites in output shown above.

-Each frame in the stack trace contains class name, method name, source
-file name, and the line number. The user can set the maximum number
-of frames collected by the HPROF agent. The default limit is 4. Stack

-The HPROF agent periodically samples the stack of all running threads

-HPROF can collect CPU usage information by injecting code into every

-There will be a "LOAD CLASS" tag for type type of each array
-in the dump. In the LOAD CLASS record, the class name string ID
-will refer to a string with a human-readable name of the array
-type that is formatted as the type name would be in Java source
