changelog

很好的命令行下载工具.开发环境为unix/linux

	Suggested by Larry Jones.

2005-04-15  Hrvoje Niksic  <[e-mail]>

	* ptimer.c: Check that _POSIX_TIMERS is defined as well as > 0.
	Problem reported by Steven M. Schweda.

2005-04-14  Hrvoje Niksic  <[e-mail]>

	* http.c (skip_short_body): Print the skipped body data in debug
	mode.
	(skip_short_body): Don't skip more than 4k of body data.
	(skip_short_body): Return whether the skipping was successful.
	(gethttp): If skip_short_body failed, invalidate the connection.

2005-04-12  Gisle Vanem  <[e-mail]>

	* ftp.c (getftp): Ditto.

	* http.c (gethttp): Open the output file in binary mode.

2005-04-11  Hrvoje Niksic  <[e-mail]>

	* hash.c: Conditionalize including config.h on HAVE_CONFIG_H
	instead of on STANDALONE.

2005-04-11  Hrvoje Niksic  <[e-mail]>

	* gen_sslfunc.c (ssl_print_errors): Made static.
	(ssl_print_errors): Eliminate potentially dangerous fixed-size
	error buffer.  Passing NULL to ERR_error_string causes it to use
	its own static buffer, which is fine for our purposes.

	* gen_sslfunc.c: Include gen_sslfunc.h.  Make the declarations of
	ssl_init and ssl_conect match the actual definitions.
	(ssl_connect): Simply return a boolean, the SSL context is no
	longer useful as a return value.

	* retr.c: Don't include SSL headers; we don't need them.

2005-04-11  Hrvoje Niksic  <[e-mail]>

	* config-post.h: Don't define _VA_LIST under Solaris; it breaks
	compilation with GCC 3.4 under Solaris 10.  (It was defined to
	avoid a warning with previous versions of GCC.)

2005-04-11  Hrvoje Niksic  <[e-mail]>

	* xmalloc.c (register_ptr): Warn the user to increase SZ prior to
	aborting.

2005-04-11  Hrvoje Niksic  <[e-mail]>

	* convert.c (convert_cleanup): Free converted_files.

2005-04-10  Hrvoje Niksic  <[e-mail]>

	* wget.h (DEBUGP): Use __builtin_expect to give a hint to GCC that
	opt.debug is false in the vast majority of cases.

2005-04-10  Hrvoje Niksic  <[e-mail]>

	* config-post.h: Declare alloca as void *, not char *.

2005-04-09  Hrvoje Niksic  <[e-mail]>

	* recur.c (download_child_p): When -p is used, (temporarily)
	ignore accept/reject rules for HTMLs, even when they are at the
	maximum recursion depth.  That is because with -p we are, if
	necessary, overstepping the max. depth to get the requisites.

2004-06-12  Larry Jones <[e-mail]>

	* recur.c (download_child_p): Correct the logic in check number 6:
	test opt.reclevel (not DEPTH) against INFINITE_RECURSION.

2005-04-09  Hrvoje Niksic  <[e-mail]>

	* url.c: Use "static const" in preference to "const static".
	Sun's cc warns that "storage class after type is obsolescent".

	* url.c (urlchr_table): Don't mark ~ as unsafe, too many broken
	web sites are confused when ~ is changed to %7E.  Their servers
	redirect /%7Efoo/ to /~foo/, which Wget again accesses using %7E,
	causing further redirections, therefore looping infinitely.  See
	Debian bug #301624 for an example.

2005-04-09  Hrvoje Niksic  <[e-mail]>

	* alloca.c: Include wget.h to be able to use xmalloc.  In addition
	to defining malloc to xmalloc, also define free to xfree.

2005-04-09  Hrvoje Niksic  <[e-mail]>

	* http-ntlm.c (ntlm_output): Use "char", not "unsigned char" for
	ntlmbuf.  Our base64 functions accept char anyway.
	(ntlm_output): Join up the format string, since we nominally
	support K&R compilers.
	(ntlm_output): Ditto.

2005-04-08  Hrvoje Niksic  <[e-mail]>

	* ptimer.c: Use Windows timers under Cygwin, whose POSIX timer
	implementation is incomplete.

2005-04-08  Hrvoje Niksic  <[e-mail]>

	* ptimer.c (struct ptimer): Remove the unused initialized field.

	* ptimer.c: Renamed function parameters from WT (which used to
	stand for wget_timer or wtimer) to PT.

2005-04-08  Hrvoje Niksic  <[e-mail]>

	* ptimer.c (posix_init): Be smarter about choosing clocks.  In
	decreasing order of preference, use CLOCK_MONOTONIC,
	CLOCK_HIGHRES, and CLOCK_REALTIME.
	(ptimer_allocate): Removed.

	* ptimer.c: Refactor the code by cleanly separating the
	architecture-dependent code from the architecture-independent
	code.

2005-04-08  Hrvoje Niksic  <[e-mail]>

	* ptimer.c (ptimer_init): Explicitly check that
	_POSIX_MONOTONIC_CLOCK is *both* defined and >=0.  (Undefined
	symbols are >=0.)

2005-04-08  Hrvoje Niksic  <[e-mail]>

	* ptimer.c (ptimer_diff): Fix typo affecting Windows build.

2005-04-08  Hrvoje Niksic  <[e-mail]>

	* ptimer.c (ptimer_init): In fact, _POSIX_MONOTONIC_CLOCK needs to
	be >= 0.

	* ptimer.c (ptimer_init): Check whether _POSIX_MONOTONIC_CLOCK is
	defined instead of whether it's greater than 0.  glibc defines it
	to 0, but still makes it available via sysconf.

2005-04-08  Hrvoje Niksic  <[e-mail]>

	* mswindows.c (str_to_int64): Rename OVERFLOW and UNDERFLOW to
	INT64_OVERFLOW and INT64_UNDERFLOW, since those names are used.

2005-04-07  Hrvoje Niksic  <[e-mail]>

	* ptimer.c: New file.  Move the "wtimer" functions from utils.c to
	this file and rename them to ptimer_.

2005-04-07  Hrvoje Niksic  <[e-mail]>

	* host.c (NO_ADDRESS): Define NO_ADDRESS only after the system
	headers have been included.

2005-04-06  Hrvoje Niksic  <[e-mail]>

	* http.c (pconn): Include NTLM data, which is per-connection.
	(known_authentication_scheme_p): Recognize NTLM authorization.
	(create_authorization_line): Call ntlm_input and ntlm_output.

	* http-ntlm.c: New file, donated by Daniel Stenberg and originally
	written for curl, heavily modified for Wget.

	* utils.c (base64_encode): Relocated from http.c, since it is now
	used by http-ntlm.c, and will possibly be used elsewhere.
	(base64_decode): New function, originally based on code from GNU
	recode.

2005-04-02  Hrvoje Niksic  <[e-mail]>

	* ftp.c (ftp_loop): Ditto.

	* ftp-basic.c (ftp_pasv): Use the xzero shorthand for memset(0).
	(ftp_lpsv): Ditto.

2005-04-05  Mauro Tortonesi  <[e-mail]>

	* Makefile.in: removed string_t.c from list of source files.

2005-04-04  Mauro Tortonesi  <[e-mail]>

	* string_t.c: Removed.
	
	* string_t.h: Removed.

2005-04-02  Hrvoje Niksic  <[e-mail]>

	* url.c (rewrite_shorthand_url): Only accept recognized schemes.
	That way "foo:80" will correctly be rewritten to "http://foo:80"
	instead of left unchanged and ultimately rejected because of
	"unsupported scheme foo".

2005-03-31  Hrvoje Niksic  <[e-mail]>

	* utils.c (number_to_string): Avoid explicit 64-bit constants;
	construct them by multiplication at compile-time.

	* utils.c, elsewhere: Don't append "L" to 32-bit integer
	constants; we aren't really compilable on 16-bit systems anyway.

	* hash.c (prime_size): Remove primes larger than 2^31, but include
	2^31-1, which is prime.

2005-03-30  Hrvoje Niksic  <[e-mail]>

	* utils.c (string_set_to_array): New function.

	* convert.c: Replace the use of "slists" with sets/hash-tables,
	which in fact suit the intended purpose much better.
	downloaded_html_list is removed altogether.

2005-03-29  Hrvoje Niksic  <[e-mail]>

	* ftp.h (enum): Rename GLOBALL, GETALL, and GETONE to
	GLOB_GLOBALL, GLOB_GETALL, and GLOB_GETONE to avoid conflict with
	Linux headers.

2005-03-29  Hrvoje Niksic  <[e-mail]>

	* utils.c (numdigit): More correct handling of negative numbers.

2005-03-21  Hrvoje Niksic  <[e-mail]>

	* http.c (gethttp): Print the human-readable size.

	* ftp.c (getftp): Print the human-readable size of the file to be
	downloaded.

	* utils.c (human_readable): New function.

	* utils.c: Renamed "legible" to "with_thousand_seps",
	"legible_large_int" to "with_thousand_seps_large", and "legible_1"
	to "add_thousand_seps".

2005-03-21  Hrvoje Niksic  <[e-mail]>

	* http.c (gethttp): Inhibit persistent connections when talking to
	proxies, as mandated by RFC 2068.

2005-03-20  Hrvoje Niksic  <[e-mail]>

	* url.c (unescape_single_char): New function.
	(url_escape_dir): Use it to unescape slashes in directory
	components.
	(url_string): Escape unsafe chars in host name, except for the ':'
	charaters, which can appear in IPv6 addresses.

	* main.c (main): Don't access the cookie jar directly.

	* log.c (escnonprint_internal): Correctly calculate the needed
	string size.  Don't forget the buffer's new size after having
	reallocated it.
	(log_cleanup): New function.  Free the escnonprint ring data.

	* init.c (cleanup): Don't free the cookie jar explicitly, it is
	now done by http_cleanup.
	(cleanup): opt.user_headers is now a vector, free it with
	free_vec.

	* http.c (gethttp): Make sure to free the request data, the status
	message, and the response data before returning from the function.
	(save_cookies): New function.
	(http_cleanup): Free the cookie jar here.

	* hash.c: Renamed string_hash to hash_string and ptrhash to
	hash_pointer.  Exported hash_pointer.

	* xmalloc.c: Organized malloc_table (previously malloc_debug) as a
	simple EQ hash table.  register_ptr and unregister_ptr are now of
	O(1) complexity.

	* xmalloc.c: Renamed "*_debug" to debugging_* and "*_real" to
	checking_*.

2005-03-12  Hrvoje Niksic  <[e-mail]>

	* utils.c (debug_test_md5): Moved to gen-md5.c.

	* mswindows.h: Don't declare inet_ntop, since we don't use it.

	* mswindows.h: For consistency, also wrap closesocket, it being
	a Winsock call.

	* mswindows.h: Don't declare sleep and usleep; we're defining
	xsleep now.

	* mswindows.h (mkdir): Don't special-case Borland C, _mkdir
	works there as well.

	* host.c: Don't include winsock header files; the correct ones
	are already included by mswindows.h.

	* mswindows.c (xsleep): Round toward the nearest millisecond
	in an attempt to avoid average short sleeps.

	* utils.c (wtimer_granularity): Report correct values for
	Windows timers and for high-resolution timers.

	* utils.c (wtimer_initialize_once): New function, called to
	initialize the timer frequency.

	* utils.c: Replace the use of GetSystemTime with high-resolution
	counters under Windows.  When high-resolution counters are
	unavailable, use GetTickCount().

2005-03-15  Hrvoje Niksic  <[e-mail]>

	* retr.c (fd_read_body): Undo the 2004-11-18 change.  Instead,
	always be "exact".

2005-03-17  Hrvoje Niksic  <[e-mail]>

	* ftp-basic.c (ftp_login): Don't free the string if ftp_response
	returned an error status because the line didn't get allocated in
	the first place.

2005-03-15  Hrvoje Niksic  <[e-mail]>

	* http.c (read_http_response_head): Limit the response size to 64k
	bytes.

	* retr.c (fd_read_hunk): Accept a MAXSIZE argument that limits the
	number of bytes the function is allowed to allocate.
	(fd_read_line): Limit the line to 4096 bytes.

2005-03-12  Hrvoje Niksic  <[e-mail]>

	* wget.h: Include options.h after wgint has been defined.

	* options.h (struct options): Declare options processed with
	cmd_bytes as wgint, not long.

2005-03-18  Hrvoje Niksic  <[e-mail]>

	* init.c (cmd_file): Use concat_strings.

	* http.c (basic_authentication_encode): Use concat_strings.

	* ftp-ls.c (ftp_index): Use concat_strings.

	* ftp-basic.c (ftp_request): Use concat_strings.

	* utils.c (concat_strings): New function.

2005-03-12  Hrvoje Niksic  <[e-mail]>

	* init.c (simple_atof): Handle negative numbers; skip whitespace
	before the number.
	(simple_atoi): Ditto.  Also, check for overflow and underflow.
	(cmd_number): Bail out on negative numbers.
	(parse_bytes_helper): Ditto.

2005-03-06  Hrvoje Niksic  <[e-mail]>

	* http.c (gethttp): Handle multiple Set-Cookie headers sent by
	remote server.

2005-03-06  Hrvoje Niksic  <[e-mail]>

	* init.c (defaults): Use passive FTP by default.

2005-03-06  Hrvoje Niksic  <[e-mail]>

	* mswindows.c: Provide wrappers to Winsock functions that set
	errno to WSAGetLastError() in case of failure.  Also provide a
	Windows-specific version of strerror.

	* mswindows.h: Wrap calls to socket, bind, connect, recv, send,
	select, getsockname, getpeername, and setsockopt.

2005-03-06  Hrvoje Niksic  <[e-mail]>

	* url.c (url_parse): Reject port numbers larger than 65535.  We
	also check for overflow while parsing port numbers.

2005-03-06  Hrvoje Niksic  <[e-mail]>

	* utils.c (read_file): Don't use wgint for file size; LFS won't
	work since the file is mmap'ed as a whole.

	* options.h: Don't include stdio.h.

	* log.c: Ditto.

	* init.c: Disambiguate assignment from non-zero test to avoid
	Borland C warning.

	Borland C warning.

	* cmpt.c (strptime_internal): Don't initialize rp_backup when
	!_NL_CURRENT to avoid Borland C warning.

2005-03-06  Hrvoje Niksic  <[e-mail]>

	available.

2005-03-05  Hrvoje Niksic  <[e-mail]>

	* url.c (url_file_name): Don't allow hosts named ".." to be
	appended as path elements.

2005-03-03  Hrvoje Niksic  <[e-mail]>
