changelog

Wget很好的处理了http和ftp的下载,很值得学习的经典代码

	* config-post.h: Replace the alloca declaration with the one from
	the latest Autoconf manual.  This should remove a warning with GCC
	on AIX.

2005-06-26  Hrvoje Niksic  <[e-mail]>

	* ftp.c (getftp): Always invoke SIZE, not only when continuing a
	download.

	* main.c (main): Ditto here.

	* progress.c (create_image): When the download is finished, print
	how long it took.

2005-06-26  Hrvoje Niksic  <[e-mail]>

	* main.c (main): Print the downloaded and quota amounts with the
	"human_readable" function.

	* ftp.c (print_length): Ditto.

	* http.c (gethttp): Don't display thousand separators.

	* utils.c (with_thousand_seps): Rewritten to respect locale
	settings and to be type size agnostic.

2005-06-25  Hrvoje Niksic  <[e-mail]>

	* utils.c (human_readable): Divide with 1024 instead of shifting
	so the operation can work with non-integer N.

2005-06-25  Hrvoje Niksic  <[e-mail]>

	* progress.c (eta_to_human): New logic for more human-readable
	ETA.

2005-06-25  Hrvoje Niksic  <[e-mail]>

	* utils.c (with_thousand_seps_sum): Decrease buffer size so it
	cannot overrun add_thousand_seps's buffer.

2005-06-25  Hrvoje Niksic  <[e-mail]>

	* utils.c (SPRINTF_WGINT): The correct format is %I64d, not just
	%I64.

2005-06-25  Hrvoje Niksic  <[e-mail]>

	* http.c (http_loop): Don't warn about wildcards in HTTP URLs if
	globbing isn't requested in the first place.

	* retr.c (retrieve_url): Temporarily turn off globbing when
	processing HTTP->FTP redirects.

2005-06-25  Hrvoje Niksic  <[e-mail]>

	* utils.c (with_thousand_seps_sum): Now defined only if
	SUM_SIZE_INT is double.

	* wget.h (SUM_SIZE_INT): Instead of bothering with long, long
	long, __int64, and friends, simply either use wgint or double, end
	of story.  Since we know how to print either, we no longer need
	LARGE_INT_FMT.

	* sysdeps.h (LARGE_INT): Renamed to SUM_SIZE_INT to better reflect
	its intent, and moved to wget.h.

2005-06-25  Hrvoje Niksic  <[e-mail]>

	* Makefile.in: No need to clean .libs.

2005-06-25  Hrvoje Niksic  <[e-mail]>

	* cookies.c (parse_set_cookies): Cast pointer subtraction to int
	before using it with %d; AIX compiler warns on this.
	Reported by Jens Schleusener.

2005-06-24  Hrvoje Niksic  <[e-mail]>

	* http.c (gethttp): Don't prepend / here.

	* cookies.c (cookie_handle_set_cookie): Prepend / to PATH.
	(cookie_header): Ditto.

2005-06-24  Hrvoje Niksic  <[e-mail]>

	* init.c: opt.verbose must be declared as int.

2005-06-23  Hrvoje Niksic  <[e-mail]>

	* cmpt.c (strpbrk): Removed.
	(mktime): Removed.
	Include <time.h>.

2005-06-23  Hrvoje Niksic  <[e-mail]>

	* utils.c (read_file): Ditto.

	* main.c (main): Use struct_fstat.

	* mswindows.h (struct_fstat): Define a struct_fstat to deal with
	the fact that Borland 5.5 has 64-bit stat, but not 64-bit fstat!

2005-06-23  Hrvoje Niksic  <[e-mail]>

	* sysdep.h: Remove code that deals with Watcom.

2005-06-22  Hrvoje Niksic  <[e-mail]>

	* all: Use bool instead of int and false/true instead of 0/non-0
	for boolean variables and values.

2005-06-22  Hrvoje Niksic  <[e-mail]>

	* sysdep.h: Include the stdbool.h/_Bool/bool blurb from Autoconf.

2005-06-22  Hrvoje Niksic  <[e-mail]>

	* init.c (cmd_lockable_boolean): Removed.

2005-06-22  Hrvoje Niksic  <[e-mail]>

	* cookies.c (struct cookie): Use 1-bit bitfields for booleans
	which makes the structure takes less space at no cost in
	complexity.

2005-06-22  Hrvoje Niksic  <[e-mail]>

	* Makefile.in ($(OBJ)): Add the config.h dependency.

2005-06-22  Hrvoje Niksic  <[e-mail]>

	* openssl.c, connect.c, host.c: Replace instances of #ifdef
	ENABLE_DEBUG if (opt.debug) {...} #endif with IF_DEBUG {...}.

	* main.c: Rename the IF_DEBUG defined here to WHEN_DEBUG.

	* wget.h (IF_DEBUG): New macro.
	(DEBUGP): Define in terms of IF_DEBUG.

2005-06-22  Hrvoje Niksic  <[e-mail]>

	* http.c (gethttp): Only handle --set-cookies (and assert that
	cookie jar exists) if opt.cookies is true.  Failure to do so
	triggered the assert when --no-cookies was used and the server
	sent a Set-Cookie header.  Ouch!

2005-06-22  Hrvoje Niksic  <[e-mail]>

	* connect.c (select_fd): Expect select() to exist.

	* utils.c (xsleep): Always use select() as sleep fallback on
	non-Windows platforms.

	* ptimer.c: Delete the implementation of PTIMER_TIME.

	* main.c: Assume existence of signal(), test for different signal
	names instead.

	* cmpt.c: Better document reasons why certain functions are
	included.

2005-06-22  Hrvoje Niksic  <[e-mail]>

	* Makefile.in: Remove the manually maintained dependency list;
	make all object files depend on every header.

2005-06-20  Hrvoje Niksic  <[e-mail]>

	* hash.c: Rename "mapping" to "cell" to avoid confusion with the
	term "mapping" (or "map") sometimes being used for the entire hash
	table.  Also rename "non-empty" to "occupied" for easier reading
	of if (!NON_EMPTY (...)) ... .

2005-06-20  Hrvoje Niksic  <[e-mail]>

	* main.c, ptimer.c, sysdep.h, utils.c: Use #elif to simplify reading of
	chained if-else-else-else-... statements.

2005-06-20  Hrvoje Niksic  <[e-mail]>

	* all: Return type of signal handlers is `void'.  Include signal.h
	unconditionally.

	* all: Don't explicitly cast values returned by malloc.  We no
	longer support ancient compilers that don't declare malloc, and we
	never supported C++ builds.

2005-06-19  Hrvoje Niksic  <[e-mail]>

	* all: Don't declare errno.  Include both time.h and sys/time.h,
	as long as sys/time.h exists.  Don't dereference function pointers
	when invoking the functions they point to.

	* cmpt.c (memmove): Remove function mandated by C89.
	(strerror): Ditto.
	(strstr): Ditto.

	* all: Undo the K&R-ization changes from 2005-05-03.

	* all: Remove support for K&R compilers: use C89 function
	declarations, remove definition of PARAMS, remove support for
	varargs, and remove ansi2knr.  Assume the presence of time.h,
	string.h, and other headers mandated by C89.

2005-06-19  Hrvoje Niksic  <[e-mail]>

	* init.c (cmd_lockable_boolean): Don't recognize literal "2" and
	"-1" values; unlike 0 and 1, those should never be exposed to the
	user.  Update the error message to be more self-consistent, as
	proposed by Benno Schulenberg.

2005-06-18  Hrvoje Niksic  <[e-mail]>

	* http.c (gethttp): Don't free "head" before using it to save
	headers.

2005-06-18  Hrvoje Niksic  <[e-mail]>

	* http.c (gethttp): When -E is in use, check for file existence
	after appending ".html" to the name and modify the file name if
	necessary.

2005-06-17  Hrvoje Niksic  <[e-mail]>

	* connect.c (socket_has_inet6): Removed.

	* host.c (lookup_host): Don't use the AI_ADDRCONFIG getaddrinfo
	hint.

2005-06-16  Hrvoje Niksic  <[e-mail]>

	* init.c (cmd_lockable_boolean): Improve the error message so it
	lists the more useful values first.

2005-06-15  Hrvoje Niksic  <[e-mail]>

	* http.c (gethttp): Also report the system error when the POST
	data file is missing.

2005-06-15  Benno Schulenberg  <[e-mail]>

	* ftp.c, http.c, connect.c, cookies.c, html-url.c, init.c, res.c:
	Gettext-ize messages that were previously missed.

2005-06-15  Hrvoje Niksic  <[e-mail]>

	* host.h (ip_address): Remove the trailing comma from the type
	enum in the no-IPv6 case.

	* main.c (struct cmdline_option): Remove the trailing comma from
	the enum.

	Reported by Jens Schleusener.

2005-05-30  Hrvoje Niksic  <[e-mail]>

	* url.c (strpbrk_or_eos): Check for a recent GCC version before
	using the statement-as-expression extension.

2005-05-30  Hrvoje Niksic  <[e-mail]>

	* http.c (gethttp): Don't attempt to "skip short body" if we're
	issuing a HEAD request (in which case the response head is not
	followed by a body).

2005-05-30  Hrvoje Niksic  <[e-mail]>

	* init.c (cmd_spec_header): Don't split the string along the
	commas using cmd_vector; just append the new value using
	vec_append instead.

	* utils.c (vec_append): New function.

2005-05-27  Andreas Beckmann  <[e-mail]>

	* html-url.c (tag_handle_link): Mark the content from the <link
	src="..."> tag as expecting HTML.

2005-05-24  Hrvoje Niksic  <[e-mail]>

	* http.c (http_atotm): Document the origin of the "cookie date"
	format.

2005-05-21  Hrvoje Niksic  <[e-mail]>

	* init.c (setval_internal): Report exact command name alongside
	the "display name".

2005-05-18  Hrvoje Niksic  <[e-mail]>

	* cookies.c (update_cookie_field): Explicitly cast -1 to time_t to
	cope with systems where time_t is unsigned.

	* cookies.c: Remove unnecessary casts to time_t from values
	already of that type.

2005-05-17  Hrvoje Niksic  <[e-mail]>

	* ftp.c (ftp_loop_internal): Same here.

	* http.c (http_loop): Don't clobber the file when -c is specified
	and the first attempt to retrieve the file fails.

2005-05-16  Hrvoje Niksic  <[e-mail]>

	* openssl.c (ssl_check_certificate): Print all issues with a
	certificate.

2005-05-16  Hrvoje Niksic  <[e-mail]>

	keep_alive was not used.

2005-05-13  Hrvoje Niksic  <[e-mail]>

	* ftp-ls.c (ftp_index): Use %d to print the port number, which is
	now int.
	From Steven M. Schweda's VMS patches.

2005-05-12  Hrvoje Niksic  <[e-mail]>

	* url.c (rewrite_shorthand_url): Don't rewrite "https://host" to
	"ftp://https//host" when SSL is not used.

2005-05-11  Hrvoje Niksic  <[e-mail]>

	* openssl.c (ssl_check_server_identity): Renamed to
	ssl_check_certificate because it does more than just checking the
	server's identity.

	--no-check-certificate.

2005-05-11  Hrvoje Niksic  <[e-mail]>

	* openssl.c (ssl_init): Always use SSL_VERIFY_NONE, so that the
	handshake finishes even if the certificate is invalid.  That way
	ssl_check_server_identity can provide better diagnostics on why
	the verification failed.

2005-05-11  Hrvoje Niksic  <[e-mail]>

	* openssl.c (pattern_match): New function.

	* openssl.c (ssl_check_server_identity): New function, verifies
	that the host name in the certificate matches the actual host
	name.
	(verify_cert_callback): Removed, since it didn't do anything
	except returning the preverify_ok argument.

	* connect.c (fd_transport_context): Allow retrieval of the context
	pointer registered with fd_register_transport.

2005-05-09  Hrvoje Niksic  <[e-mail]>

	* openssl.c (verify_cert_callback): Renamed from verify_callback.
	Always return the received "ok" value.  Print the X509 name in
	debug mode.

	* http.c (http_loop): Check for wildcards in the URL path
	component, not in the whole URL.

	* ftp.c (ftp_loop): Check for wildcards in URL path before
