+
+	* test/base_test.py (BaseTest.gen_cmd_line): Add support for running all
+	tests through valgrind if the relevant environment variable is set
+	* conf/expected_ret_code (ExpectedRetCode.__call__): Valgrind returns error
+	code 45 when it detects a memory leak.
+	* Readme: Update with details about valgrind tests
+
+2014-07-22  Darshit Shah  <darnir@gmail.com>
+
+	* (README): Remove old TODO and document SERVER_WAIT variable
+
+2014-06-22  Darshit Shah  <darnir@gmail.com>
+
+	* (conf.files_crawled): diff is a set object and needs explicit str
+	conversion.
+
+2014-03-13  Zihang Chen  <chsc4698@gmail.com>
+
+	* base_test.py:
+	(CommonMethods): Rename to BaseTest.
+	(BaseTest): Implement __init__ method where the class-wide variables are
+	initialized. Also variable names like `xxx_list` is renamed to its plural
+	form, e.g. `server_list` => `servers`.
+	(BaseTest.init_test_env): Remove name argument due to its unnecessarity.
+	(BaseTest.get_test_dir): Because the path of the test directory is needed
+	in multiple methods, this method is implemented.
+	(BaseTest.get_domain_addr): Rewrite the return statement utilizing str
+	formatting (which is more Pythonic).
+	(BaseTest.get_cmd_line): Rename to gen_cmd_line. Change the variables with
+	capitcal characters to lower ones. Also, the nested for loop is rewritten
+	to a plain loop using the zip function.
+	(BaseTest.__gen_local_filesys): Rename to gen_local_fs_snapshot. Move to
+	ExpectedFiles in conf/expected_files.py and is marked as a static
+	method. Refactor to a less verbose implementation.
+	(BaseTest._check_downloaded_files): Rename to __call__ to agree with the
+	invocation in test case classes. Move to ExpectedFiles in
+	conf/expected_files.py.
+	(BaseTest.get_server_rules): Refactor to a more Pythonic form utilizing
+	dict.items() and is marked static.
+	(BaseTest.stop_server): (new method) an abstract method which should stop
+	the currently using servers.
+	(BaseTest.instantiate_server_by): (new method) an abstract method which
+	should instantiate a server instance according to the given argument.
+	(BaseTest.__enter__): (new method) method which initialize the context
+	manager
+	(BaseTest.__exit__): (new method) method that finilize the context manager
+	and deal with the exceptions during the execution of the with statement,
+	subclasses can override this method for extensibility
+	* http_test.py:
+	(HTTPTest.__init__): Add call to super.__init__. Default values of
+	pre_hook, test_params, post_hook are set to None to avoid a subtle bug of
+	Python. Argument servers is renamed to protocols.
+	(HTTPTest.Server_setup): Move to BaseTest and rename to server_setup.
+	Calls to pre_hook_call, call_test, post_hook_call are removed.
+	(HTTPTest.hook_call, pre_hook_call, call_test, post_hook_call): Move to
+	BaseTest for that both HTTP test cases and FTP test cases may use these
+	methods.
+	(HTTPTest.init_HTTP_Server, init_HTTPS_Server): Merge and rename to
+	instantiate_server_by to implement the abstract method in BaseTest.
+	(HTTPTest.stop_HTTP_Server): Rename to stop_server to implement the
+	abstract method in BaseTest. Also, pull out the part where remaining
+	requests are gathered into a new method request_remaining.
+	(BaseTest.act_retcode): Rename to ret_code because ExpectedRetCode is
+	moved out from BaseTest, so the name act_retcode is actually a bit
+	verbose.
+	* conf/expected_ret_code.py:
+	(ExpectedRetCode.__call__): Rewrite the str into a more readable form.
+	* conf/files_crawled.py:
+	(FilesCrawled.__call__): Refactor this method into a more Pythonic form
+	utilizing the zip function.
+	* conf/local_files.py:
+	(LocalFiles__call__): Rewrite this method with the recommended with
+	statement.
+	* conf/server_conf.py:
+	(ServerConf.__call__): Rewrite this method due to BaseTest.server_list is
+	renamed to BaseTest.servers.

+	utilizing the zip function.
+	* conf/urls.py:
+	(URLs): Rename url_list to urls.
+	* conf/wget_commands.py:
+	(WgetCommands): Rename command_list to commands, rename test_obj.options
+	to test_obj.wget_options.
+	* Test--https.py, Test-Proto.py, Test-Parallel-Proto.py: Argument servers
+	is changed to protocols due to change in the signature of

-    Since, we do not have a direct mechanism for conditionally sending responses
-    via the HTTP Server, I've used a workaround.
-    The server will always respond to a request for File1 with a 504 Gateway
-    Timeout. Using the --tries=2 option, we ensure that Wget attempts the file

-
-    In this case, we expect Wget to attempt File1 twice and File2 once. If Wget
