-// Functions in this file support the public context API, including

-// 1. Efficient conversion to/from wire format
-// 2. Minimal bytes used on-wire
-// 3. Efficient context creation
-// 4. Efficient lookup of tag value for a key
-// 5. Efficient iteration over tags
-// 6. Minimal memory footprint
-//
-// Notes on tradeoffs/decisions:

-
-// Implements an efficient in-memory log, optimized for multiple writers and
-// a single reader. Available log space is divided up in blocks of
-// CENSUS_LOG_2_MAX_RECORD_SIZE bytes. A block can be in one of the following
-// three data structures:
-// - Free blocks (free_block_list)
-// - Blocks with unread data (dirty_block_list)
-// - Blocks currently attached to cores (core_local_blocks[])
-//
-// census_log_start_write() moves a block from core_local_blocks[] to the end of
-// dirty_block_list when block:
-// - is out-of-space OR
-// - has an incomplete record (an incomplete record occurs when a thread calls
-// census_log_start_write() and is context-switched before calling
-// census_log_end_write()
-// So, blocks in dirty_block_list are ordered, from oldest to newest, by the
-// time when block is detached from the core.
-//
-// census_log_read_next() first iterates over dirty_block_list and then
-// core_local_blocks[]. It moves completely read blocks from dirty_block_list
-// to free_block_list. Blocks in core_local_blocks[] are not freed, even when
-// completely read.
-//
-// If the log is configured to discard old records and free_block_list is empty,
-// census_log_start_write() iterates over dirty_block_list to allocate a
-// new block. It moves the oldest available block (no pending read/write) to
-// core_local_blocks[].
-//
-// core_local_block_struct is used to implement a map from core id to the block
-// associated with that core. This mapping is advisory. It is possible that the
-// block returned by this mapping is no longer associated with that core. This
-// mapping is updated, lazily, by census_log_start_write().
-//
-// Locking in block struct:
-//
-// Exclusive g_log.lock must be held before calling any functions operating on
-// block structs except census_log_start_write() and census_log_end_write().
-//
-// Writes to a block are serialized via writer_lock. census_log_start_write()
-// acquires this lock and census_log_end_write() releases it. On failure to
-// acquire the lock, writer allocates a new block for the current core and
-// updates core_local_block accordingly.
-//
-// Simultaneous read and write access is allowed. Readers can safely read up to
-// committed bytes (bytes_committed).
-//
-// reader_lock protects the block, currently being read, from getting recycled.
-// start_read() acquires reader_lock and end_read() releases the lock.
-//
-// Read/write access to a block is disabled via try_disable_access(). It returns
-// with both writer_lock and reader_lock held. These locks are subsequently
-// released by enable_access() to enable access to the block.
-//
-// A note on naming: Most function/struct names are prepended by cl_
-// (shorthand for census_log). Further, functions that manipulate structures
-// include the name of the structure, which will be passed as the first
-// argument. E.g. cl_block_initialize() will initialize a cl_block.

+
+ The parser object keeps track of a function pointer which represents the

+ Each time new bytes are presented, we call into the current state, which

+
+ The parse state that terminates then saves its function pointer to be the
+ current state so that it can resume when more bytes are available.

- * wakeup_fd abstracts the concept of a file descriptor for the purpose of
- * waking up a thread in select()/poll()/epoll_wait()/etc.
-
- * The poll() family of system calls provide a way for a thread to block until
- * there is activity on one (or more) of a set of file descriptors. An
- * application may wish to wake up this thread to do non file related work. The
- * typical way to do this is to add a pipe to the set of file descriptors, then
- * write to the pipe to wake up the thread in poll().
- *
- * Linux has a lighter weight eventfd specifically designed for this purpose.
- * wakeup_fd abstracts the difference between the two.
- *
- * Setup:
- * 1. Before calling anything, call global_init() at least once.
- * 1. Call grpc_wakeup_fd_create() to get a wakeup_fd.
- * 2. Add the result of GRPC_WAKEUP_FD_FD to the set of monitored file
- * descriptors for the poll() style API you are using. Monitor the file
- * descriptor for readability.
- * 3. To tear down, call grpc_wakeup_fd_destroy(). This closes the underlying
- * file descriptor.
- *
- * Usage:
- * 1. To wake up a polling thread, call grpc_wakeup_fd_wakeup() on a wakeup_fd
- * it is monitoring.
- * 2. If the polling thread was awakened by a wakeup_fd event, call
- * grpc_wakeup_fd_consume_wakeup() on it.

+// 3. Efficient context creation
+// 4. Efficient lookup of tag value for a key
+// 5. Efficient iteration over tags
+// 6. Minimal memory footprint
+//
+// Notes on tradeoffs/decisions:
+// * tag includes 1 byte length of key, as well as nil-terminating byte. These
+// are to aid in efficient parsing and the ability to directly return key
+// strings. This is more important than saving a single byte/tag on the wire.
+// * The wire encoding uses only single byte values. This eliminates the need
+// to handle endian-ness conversions. It also means there is a hard upper
+// limit of 255 for both CENSUS_MAX_TAG_KV_LEN and CENSUS_MAX_PROPAGATED_TAGS.

+// Implements an efficient in-memory log, optimized for multiple writers and
+// a single reader. Available log space is divided up in blocks of
+// CENSUS_LOG_2_MAX_RECORD_SIZE bytes. A block can be in one of the following
+// three data structures:
+// - Free blocks (free_block_list)
+// - Blocks with unread data (dirty_block_list)
+// - Blocks currently attached to cores (core_local_blocks[])
+//
+// census_log_start_write() moves a block from core_local_blocks[] to the end of
+// dirty_block_list when block:
+// - is out-of-space OR
+// - has an incomplete record (an incomplete record occurs when a thread calls
+// census_log_start_write() and is context-switched before calling
+// census_log_end_write()
+// So, blocks in dirty_block_list are ordered, from oldest to newest, by the
+// time when block is detached from the core.
+//
+// census_log_read_next() first iterates over dirty_block_list and then
+// core_local_blocks[]. It moves completely read blocks from dirty_block_list
+// to free_block_list. Blocks in core_local_blocks[] are not freed, even when
+// completely read.
+//
+// If the log is configured to discard old records and free_block_list is empty,
+// census_log_start_write() iterates over dirty_block_list to allocate a
+// new block. It moves the oldest available block (no pending read/write) to
+// core_local_blocks[].
+//
+// core_local_block_struct is used to implement a map from core id to the block
+// associated with that core. This mapping is advisory. It is possible that the
+// block returned by this mapping is no longer associated with that core. This
+// mapping is updated, lazily, by census_log_start_write().
+//
+// Locking in block struct:
+//
+// Exclusive g_log.lock must be held before calling any functions operating on
+// block structs except census_log_start_write() and census_log_end_write().
+//
+// Writes to a block are serialized via writer_lock. census_log_start_write()
+// acquires this lock and census_log_end_write() releases it. On failure to
+// acquire the lock, writer allocates a new block for the current core and
+// updates core_local_block accordingly.
+//
+// Simultaneous read and write access is allowed. Readers can safely read up to
+// committed bytes (bytes_committed).
+//
+// reader_lock protects the block, currently being read, from getting recycled.
+// start_read() acquires reader_lock and end_read() releases the lock.
+//
+// Read/write access to a block is disabled via try_disable_access(). It returns
+// with both writer_lock and reader_lock held. These locks are subsequently
+// released by enable_access() to enable access to the block.
+//
+// A note on naming: Most function/struct names are prepended by cl_
+// (shorthand for census_log). Further, functions that manipulate structures
+// include the name of the structure, which will be passed as the first
+// argument. E.g. cl_block_initialize() will initialize a cl_block.

+ * wakeup_fd abstracts the concept of a file descriptor for the purpose of
+ * waking up a thread in select()/poll()/epoll_wait()/etc.
+
+ * The poll() family of system calls provide a way for a thread to block until
+ * there is activity on one (or more) of a set of file descriptors. An
+ * application may wish to wake up this thread to do non file related work. The
+ * typical way to do this is to add a pipe to the set of file descriptors, then
+ * write to the pipe to wake up the thread in poll().
+ *
+ * Linux has a lighter weight eventfd specifically designed for this purpose.
+ * wakeup_fd abstracts the difference between the two.
+ *
+ * Setup:
+ * 1. Before calling anything, call global_init() at least once.
+ * 1. Call grpc_wakeup_fd_create() to get a wakeup_fd.
+ * 2. Add the result of GRPC_WAKEUP_FD_FD to the set of monitored file
+ * descriptors for the poll() style API you are using. Monitor the file
+ * descriptor for readability.
+ * 3. To tear down, call grpc_wakeup_fd_destroy(). This closes the underlying
+ * file descriptor.
+ *
+ * Usage:
+ * 1. To wake up a polling thread, call grpc_wakeup_fd_wakeup() on a wakeup_fd
+ * it is monitoring.
+ * 2. If the polling thread was awakened by a wakeup_fd event, call
+ * grpc_wakeup_fd_consume_wakeup() on it.

+/* Available log space is divided up in blocks of
+ CENSUS_LOG_2_MAX_RECORD_SIZE bytes. A block can be in one of the
+ following three data structures:
+ - Free blocks (free_block_list)
+ - Blocks with unread data (dirty_block_list)
+ - Blocks currently attached to cores (core_local_blocks[])
+
+ census_log_start_write() moves a block from core_local_blocks[] to the
+ end of dirty_block_list when block:
+ - is out-of-space OR
+ - has an incomplete record (an incomplete record occurs when a thread calls
+ census_log_start_write() and is context-switched before calling
+ census_log_end_write()
+ So, blocks in dirty_block_list are ordered, from oldest to newest, by time
+ when block is detached from the core.
+
+ census_log_read_next() first iterates over dirty_block_list and then
+ core_local_blocks[]. It moves completely read blocks from dirty_block_list
+ to free_block_list. Blocks in core_local_blocks[] are not freed, even when
+ completely read.
+
+ If log is configured to discard old records and free_block_list is empty,
+ census_log_start_write() iterates over dirty_block_list to allocate a
+ new block. It moves the oldest available block (no pending read/write) to
+ core_local_blocks[].
+
+ core_local_block_struct is used to implement a map from core id to the block
+ associated with that core. This mapping is advisory. It is possible that the
+ block returned by this mapping is no longer associated with that core. This
+ mapping is updated, lazily, by census_log_start_write().
+
+ Locking in block struct:
+
+ Exclusive g_log.lock must be held before calling any functions operatong on
+ block structs except census_log_start_write() and
+ census_log_end_write().
+
+ Writes to a block are serialized via writer_lock.
+ census_log_start_write() acquires this lock and
+ census_log_end_write() releases it. On failure to acquire the lock,
+ writer allocates a new block for the current core and updates
+ core_local_block accordingly.
+
+ Simultaneous read and write access is allowed. Reader can safely read up to
+ committed bytes (bytes_committed).
+
+ reader_lock protects the block, currently being read, from getting recycled.
+ start_read() acquires reader_lock and end_read() releases the lock.
+
+ Read/write access to a block is disabled via try_disable_access(). It returns
+ with both writer_lock and reader_lock held. These locks are subsequently
+ released by enable_access() to enable access to the block.
+
+ A note on naming: Most function/struct names are prepended by cl_
+ (shorthand for census_log). Further, functions that manipulate structures
+ include the name of the structure, which will be passed as the first
+ argument. E.g. cl_block_initialize() will initialize a cl_block.

+/* This file provides a mechanism for tracking metadata through the grpc stack.
+ It's not intended for consumption outside of the library.
+
+ Metadata is tracked in the context of a grpc_mdctx. For the time being there
+ is one of these per-channel, avoiding cross channel interference with memory
+ use and lock contention.
+
+ The context tracks unique strings (grpc_mdstr) and pairs of strings
+ (grpc_mdelem). Any of these objects can be checked for equality by comparing
+ their pointers. These objects are reference counted.
+
+ grpc_mdelem can additionally store a (non-NULL) user data pointer. This
+ pointer is intended to be used to cache semantic meaning of a metadata
+ element. For example, an OAuth token may cache the credentials it represents
+ and the time at which it expires in the mdelem user data.
+
+ Combining this metadata cache and the hpack compression table allows us to
+ simply lookup complete preparsed objects quickly, incurring a few atomic
+ ops per metadata element on the fast path.
+
+ grpc_mdelem instances MAY live longer than their refcount implies, and are
+ garbage collected periodically, meaning cached data can easily outlive a
+ single request.
+
+ STATIC METADATA: in static_metadata.h we declare a set of static metadata.
+ These mdelems and mdstrs are available via pre-declared code generated macros
+ and are available to code anywhere between grpc_init() and grpc_shutdown().
+ They are not refcounted, but can be passed to _ref and _unref functions
+ declared here - in which case those functions are effectively no-ops. */

-/* Available log space is divided up in blocks of
- CENSUS_LOG_2_MAX_RECORD_SIZE bytes. A block can be in one of the
- following three data structures:
- - Free blocks (free_block_list)
- - Blocks with unread data (dirty_block_list)
- - Blocks currently attached to cores (core_local_blocks[])
-
- census_log_start_write() moves a block from core_local_blocks[] to the
- end of dirty_block_list when block:
- - is out-of-space OR
- - has an incomplete record (an incomplete record occurs when a thread calls
- census_log_start_write() and is context-switched before calling
- census_log_end_write()
- So, blocks in dirty_block_list are ordered, from oldest to newest, by time
- when block is detached from the core.
-
- census_log_read_next() first iterates over dirty_block_list and then
- core_local_blocks[]. It moves completely read blocks from dirty_block_list
- to free_block_list. Blocks in core_local_blocks[] are not freed, even when
- completely read.
-
- If log is configured to discard old records and free_block_list is empty,
- census_log_start_write() iterates over dirty_block_list to allocate a
- new block. It moves the oldest available block (no pending read/write) to
- core_local_blocks[].
-
- core_local_block_struct is used to implement a map from core id to the block
- associated with that core. This mapping is advisory. It is possible that the
- block returned by this mapping is no longer associated with that core. This
- mapping is updated, lazily, by census_log_start_write().
-
- Locking in block struct:
-
- Exclusive g_log.lock must be held before calling any functions operatong on
- block structs except census_log_start_write() and
- census_log_end_write().
-
- Writes to a block are serialized via writer_lock.
- census_log_start_write() acquires this lock and
- census_log_end_write() releases it. On failure to acquire the lock,
- writer allocates a new block for the current core and updates
- core_local_block accordingly.
-
- Simultaneous read and write access is allowed. Reader can safely read up to
- committed bytes (bytes_committed).
-
- reader_lock protects the block, currently being read, from getting recycled.
- start_read() acquires reader_lock and end_read() releases the lock.
-
- Read/write access to a block is disabled via try_disable_access(). It returns
- with both writer_lock and reader_lock held. These locks are subsequently
- released by enable_access() to enable access to the block.
-
- A note on naming: Most function/struct names are prepended by cl_
- (shorthand for census_log). Further, functions that manipulate structures
- include the name of the structure, which will be passed as the first
- argument. E.g. cl_block_initialize() will initialize a cl_block.

-/* Keep rolling sums of a user-defined statistic (containing a number of
- measurements) over a a number of time intervals ("windows"). For example,
- you can use a window_stats object to answer questions such as
- "Approximately how many RPCs/s did I receive over the past minute, and
- approximately how many bytes did I send out over that period?".
-
- The type of data to record, and the time intervals to keep are specified
- when creating the object via a call to census_window_stats_create().
-
- A window's interval is divided into one or more "buckets"; the interval
- must be divisible by the number of buckets. Internally, these buckets
- control the granularity of window_stats' measurements. Increasing the
- number of buckets lets the object respond more quickly to changes in the
- overall rate of data added into the object, at the cost of additional
- memory usage.

- 4 buckets.

-/* This file provides a mechanism for tracking metadata through the grpc stack.
- It's not intended for consumption outside of the library.
-
- Metadata is tracked in the context of a grpc_mdctx. For the time being there
- is one of these per-channel, avoiding cross channel interference with memory
- use and lock contention.
-
- The context tracks unique strings (grpc_mdstr) and pairs of strings
- (grpc_mdelem). Any of these objects can be checked for equality by comparing
- their pointers. These objects are reference counted.
-
- grpc_mdelem can additionally store a (non-NULL) user data pointer. This
- pointer is intended to be used to cache semantic meaning of a metadata
- element. For example, an OAuth token may cache the credentials it represents
- and the time at which it expires in the mdelem user data.
-
- Combining this metadata cache and the hpack compression table allows us to
- simply lookup complete preparsed objects quickly, incurring a few atomic
- ops per metadata element on the fast path.
-
- grpc_mdelem instances MAY live longer than their refcount implies, and are
- garbage collected periodically, meaning cached data can easily outlive a

-> Launches the 5 instances of stress test clients, 1 instance of stress test server and runs the test for 180 seconds. The test would be run on the default container cluster (that you have set in `gcloud`) in the project `sree-gce`.
-
-> Note: we currently do not have the ability to launch multiple instances of the server. This can be added very easily in future
+> The above runs the stress test on GKE under the project `sree-gce` in the default cluster (that you set by `gcloud` command earlier). The test settings (like number of client instances, servers, the parmeters to pass, test cases etc) are all loaded from the config file `$GRPC_ROOT/tools/run_tests/stress_test/opt.json`
