Additionaly, it should compile 11 | (and run) on BSD, Solaris, Darwin (Mac OS X) and Win32 (Cygwin) systems. 12 | 13 | If the configure script does weird things on your system, please do warn me! 14 | I test it on as many machines and OS'es as possible, but still anything can 15 | go wrong. 16 | 17 | 18 | 19 | How to install/use 20 | ------------------ 21 | 22 | 23 | Run the configure script (you can supply some options if you want, try 24 | `./configure --help` for more info) and then run `make`. The program should 25 | compile then. There are no special requirements for Axel. You can install 26 | the program using `make install` or you can just run it from the current 27 | directory. You can copy the `axelrc.example` file to `~/.axelrc` then, if you 28 | want to change some of the settings. 29 | 30 | 31 | Run the program like this: 32 | 33 | ``` 34 | axel ftp://ftp.nl.kernel.org/pub/linux/kernel/v2.2/linux-2.2.20.tar.bz2 35 | ``` 36 | 37 | 38 | For a simple single-server-multiple-connection download, or: 39 | 40 | ``` 41 | axel ftp://ftp.{nl,be,de}.kernel.org/pub/linux/kernel/v2.2/linux-2.2.20.tar.bz2 42 | ``` 43 | 44 | If you want to use those three servers for the download. The program can do 45 | an automatic search for FTP mirrors as well (filesearching.com), but that's 46 | not yet perfect... Just try the `-S` option. (The line above should at least 47 | work with the Bash shell. You can type all the mirrors by hand as well, if 48 | you really want to, and/or of necessary...) 49 | 50 | 51 | Just one other thing you should keep in mind when using this program: Some 52 | FTP operators don't like people who use download accelerators. To quote an 53 | administrator at Progeny.Com in a mail to me: 54 | 55 | > Additionally, I should mention that accelerated downloads are 56 | > discouraged as I consider them abusive. 57 | 58 | And he certainly has a point.. Using more than one server at once is a fine 59 | solution IMHO, so please use this feature if possible! 60 | 61 | Wilmer van der Gaast. 62 | -------------------------------------------------------------------------------- /Makefile: -------------------------------------------------------------------------------- 1 | ########################### 2 | ## Makefile for Axel ## 3 | ## ## 4 | ## Copyright 2001 Lintux ## 5 | ########################### 6 | 7 | ### DEFINITIONS 8 | 9 | -include Makefile.settings 10 | 11 | .SUFFIXES: .po .mo 12 | 13 | # Add your translation here.. 14 | MOFILES = nl.mo de.mo ru.mo zh_CN.mo 15 | 16 | 17 | all: $(OUTFILE) 18 | install: install-bin install-etc install-man 19 | uninstall: uninstall-bin uninstall-etc uninstall-man 20 | 21 | clean: 22 | rm -f *.o $(OUTFILE) search core *.mo 23 | 24 | distclean: clean 25 | rm -f Makefile.settings config.h axel-*.tar axel-*.tar.gz axel-*.tar.bz2 26 | 27 | install-man: 28 | mkdir -p $(DESTDIR)$(MANDIR)/man1/ 29 | cp axel.1 $(DESTDIR)$(MANDIR)/man1/axel.1 30 | mkdir -p $(DESTDIR)$(MANDIR)/zh_CN/man1/ 31 | cp axel_zh_CN.1 $(DESTDIR)$(MANDIR)/zh_CN/man1/axel.1 32 | 33 | uninstall-man: 34 | rm -f $(MANDIR)/man1/axel.1 35 | rm -f $(MANDIR)/zh_CN/man1/axel.1 36 | 37 | install-etc: 38 | mkdir -p $(DESTDIR)$(ETCDIR)/ 39 | cp axelrc.example $(DESTDIR)$(ETCDIR)/axelrc 40 | 41 | uninstall-etc: 42 | rm -f $(ETCDIR)/axelrc 43 | 44 | ### MAIN PROGRAM 45 | 46 | $(OUTFILE): axel.o conf.o conn.o ftp.o http.o search.o tcp.o text.o 47 | $(CC) *.o -o $(OUTFILE) $(LFLAGS) 48 | $(STRIP) $(OUTFILE) 49 | 50 | .c.o: 51 | $(CC) -c $*.c -o $*.o $(CFLAGS) 52 | 53 | install-bin: 54 | mkdir -p $(DESTDIR)$(BINDIR)/ 55 | cp $(OUTFILE) $(DESTDIR)$(BINDIR)/$(OUTFILE) 56 | 57 | uninstall-bin: 58 | rm -f $(BINDIR)/$(OUTFILE) 59 | 60 | tar: 61 | version=`sed -n 's/#define AXEL_VERSION_STRING[ \t]*"\([^"]*\)"/\1/p' < axel.h` && \ 62 | tar --create --numeric-owner --owner 0 --group 0 --transform "s#^#axel-$${version}/#" "--file=axel-$${version}.tar" --exclude-vcs -- *.c *.h *.po *.1 configure Makefile axelrc.example gui API CHANGES COPYING CREDITS README && \ 63 | gzip --best < "axel-$${version}.tar" > "axel-$${version}.tar.gz" && \ 64 | bzip2 --best < "axel-$${version}.tar" > "axel-$${version}.tar.bz2" 65 | 66 | 67 | ### I18N FILES 68 | 69 | %.po: 70 | -@mv $@ $@.bak 71 | xgettext -k_ -o$@ *.[ch] 72 | @if [ -e $@.bak ]; then \ 73 | echo -n Merging files...; \ 74 | msgmerge -vo $@.combo $@.bak $@; \ 75 | rm -f $@ $@.bak; \ 76 | mv $@.combo $@; \ 77 | fi 78 | 79 | .po.mo: $@.po 80 | msgfmt -vo $@ $*.po 81 | 82 | i18n-mofiles: $(MOFILES) 83 | 84 | install-i18n: 85 | @echo Installing locale files... 86 | @for i in $(MOFILES); do \ 87 | mkdir -p $(DESTDIR)$(LOCALE)/`echo $$i | cut -d. -f1`/LC_MESSAGES/; \ 88 | cp $$i $(DESTDIR)$(LOCALE)/`echo $$i | cut -d. -f1`/LC_MESSAGES/axel.mo; \ 89 | done 90 | 91 | uninstall-i18n: 92 | cd $(LOCALE); find . -name axel.mo -exec 'rm' '{}' ';' 93 | -------------------------------------------------------------------------------- /gui/kapt/axel-kapt: -------------------------------------------------------------------------------- 1 | #!/usr/bin/env python 2 | # Copyright 2001 by Paul Evans 3 | # Sat Oct 20 01:15:11 2001 Paul Evans 4 | # v 0.3 5 | # This grammar is free software; you can redistribute it and/or modify 6 | # it under the terms of the GNU General Public License as published by 7 | # the Free Software Foundation; either version 2 of the License, 8 | # or (at your option) any later version. 9 | 10 | # This grammar is distributed in the hope that it will be useful, 11 | # but WITHOUT ANY WARRANTY; without even the implied warranty of 12 | # MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

Refer to the bugtracker ( https://alioth.debian.org/tracker/?group_id=100070&atid=413085 ) for detailled information. 11 | Pre-release version numbers of Axel 3 will start with 2.99. Starting with the 3.x series, the following version scheme will be adopted: 12 | 13 | x.y.z 14 | 15 | x: Complete overhaul of the code structure 16 | y: New features and/or speed/size improvements 17 | z: Bug fixed 18 | 19 | Features 20 | ======== 21 | 22 | * HTTP authentication (#310785) 23 | This is actually already implemented and should be documented. Using -H is possible, too. 24 | 25 | * Metalink (#310625) 26 | Basic Metalink support should not be that difficult. However, it will only be compiled if METALINK is defined. Metalink support will require libxml2. As libmetalink is currently unusable for us (private symbols), we'll implement the format ourselves. 27 | 28 | * .netrc (#310635) 29 | There are lots of GPLed implementations flying around. To minimize code size, it shouldn't be compiled in by default if the code exceeds a couple of bytes. Anyway, it's just one call from Axel's point of view. 30 | 31 | * Prevent connection to same server (#310638) 32 | See tcp.c below for the implementation (aside from a flag in the configuration and a cli flag). 33 | 34 | * Force overriding state file (#311022) 35 | Shouldn't be difficult and take more than a couple of bytes. 36 | 37 | * SSL protocols (HTTPS, FTPS) (#311163) 38 | 39 | * Parse Content-Disposition header (#311101) 40 | Look if the specific problem mentioned in the bug is fixed by this. 41 | 42 | Code structure 43 | ============== 44 | 45 | * conn.c 46 | needs cleanup, possibly even elimination. Most functions look like 47 | if (ftp && !proxy) { 48 | // ... do FTP stuff (15 lines) 49 | } else { 50 | // ... do HTTP stuff (20 lines) 51 | } 52 | We should at least abstract the switch between HTTP and FTP and look what can be done about simplifiying and documenting the functions here. 53 | 54 | Furthermore, redirecting should be cached somehow/done only once lest we reach the redirect limit because it's less than -n. 55 | * tcp.c 56 | should be checked. The functions look a little bit obscure to me. But maybe, that's just me. Before we implement #310638, we should include some round-robin trickery in here. 57 | * Removing MAX_STRING(#311085) and MAX_ADD_HEADERS. These are arbitrary restrictions and may hide a number of strange bugs. Furthermore, statically sized fields are a waste of memory. 58 | * Add die messages: Axel must not exit with != 0 without telling why. 59 | * Add debugging messages: When compiled with DEBUG, Axel could be more verbose. This won't harm anything and may serve as comments. 60 | * Some functions could use a little bit of documentation. 61 | * Remove all logic from text.c 62 | * Ensure correct synchronization of thread state (volatile?) 63 | * Cleanup AXEL_LEGACY 64 | * rewrite axel-kapt to be sane (probably sh, or even #!/usr/bin/env kaptain suffices) or remove it in favor of a sane GUI 65 | 66 | Bugs 67 | ==== 68 | 69 | We're gonna fix them all! 70 | #310979 seems pretty vague. 71 | 72 | Check spaces in FTP and HTTP URLs 73 | 74 | (User) Documentation 75 | ==================== 76 | 77 | * As previously mentioned, authentication should be documented. 78 | * Update API 79 | 80 | 3.1 81 | === 82 | 83 | * Cookies (#310835) 84 | Can be implemented via -H. The bug called for reading the Netcape-style cookies.txt (Wget's --load--cokies option). Domain-specific cookies could be rather complex to implement. If the implementation of this feature costs more than 100B, it should be deselectable. 85 | * Rate-limit status messages (#TODO) 86 | * Don't discard first HTTP connection, but use it adaptively (start requests from the end, RST as soon as first task is fullfilled) 87 | * A -1 option: Just make one request, and only one. 88 | * IPv6 support 89 | 90 | 3.2 91 | === 92 | 93 | * Write a macro ERROR_MESSAGE(msg) (msg), enclose all _("some long error message") and offer a compilation option for a single error message, see if that yields any size improvements 94 | * Check compilation with dietlibc(http://www.fefe.de/dietlibc/) and uclibc(http://www.uclibc.org/): 95 | · How to compile with these libraries 96 | · Does this actually improve the binary size? 97 | · Check warnings/suggestions 98 | * valgrind and friends 99 | * Test very large -n values. Check pthread thread stack size. 100 | 101 | Future/Ideas 102 | ============ 103 | 104 | * Real FTPS (AUTH)? 105 | * Allow downloading to /dev/null for debugging or speed test purposes (Statefile in memory or so) 106 | * Desktop integration, look who likes download accelerators 107 | * Check the syscalls we make. Check whether timing and read() calls can be optimized 108 | * Write automated tests to test all these nifty corner cases. Either a test webserver or LD_PRELOAD injection of all syscalls (see libfake*) 109 | * Write a helper script that displays the final binary size for different configurations to determine what a particular feature costs 110 | * Document and implement coding conventions, versioning scheme 111 | -------------------------------------------------------------------------------- /axel.1: -------------------------------------------------------------------------------- 1 | .\" 2 | .\"man-page for Axel 3 | .\" 4 | .\"Derived from the man-page example in the wonderful book called Beginning 5 | .\"Linux Programming, written by Richard Stone and Neil Matthew. 6 | .\" 7 | .TH AXEL 1 8 | 9 | .SH NAME 10 | \fBAxel\fP \- A light download accelerator for Linux. 11 | 12 | .SH SYNOPSIS 13 | .B axel 14 | [\fIOPTIONS\fP] \fIurl1\fP [\fIurl2\fP] [\fIurl...\fP] 15 | 16 | .SH DESCRIPTION 17 | Axel is a program that downloads a file from a FTP or HTTP server through 18 | multiple connection, each connection downloads its own part of the file. 19 | 20 | Unlike most other programs, Axel downloads all the data directly to the 21 | destination file, using one single thread. It just saves some time at the 22 | end because the program doesn't have to concatenate all the downloaded 23 | parts. 24 | 25 | .SH OPTIONS 26 | .PP 27 | One argument is required, the URL to the file you want to download. When 28 | downloading from FTP, the filename may contain wildcards and the program 29 | will try to resolve the full filename. Multiple URL's can be specified 30 | as well and the program will use all those URL's for the download. Please 31 | note that the program does not check whether the files are equal. 32 | 33 | .PP 34 | Other options: 35 | 36 | .TP 37 | \fB\-\-max\-speed=x\fP, \fB\-s\ x\fP 38 | You can specify a speed (bytes per second) here and Axel will try 39 | to keep the average speed around this speed. Useful if you don't want 40 | the program to suck up all of your bandwidth. 41 | 42 | .TP 43 | \fB\-\-num\-connections=x\fP, \fB\-n\ x\fP 44 | You can specify an alternative number of connections here. 45 | 46 | .TP 47 | \fB\-\-output=x\fP, \fB\-o\ x\fP 48 | Downloaded data will be put in a local file with the same name, 49 | unless you specify a different name using this option. You can 50 | specify a directory as well, the program will append the filename. 51 | 52 | .TP 53 | \fB\-\-search[=x]\fP, \fB-S[x]\fP 54 | Axel can do a search for mirrors using the filesearching.com search 55 | engine. This search will be done if you use this option. You can specify how 56 | many different mirrors should be used for the download as well. 57 | 58 | The search for mirrors can be time\-consuming because the program tests 59 | every server's speed, and it checks whether the file's still available. 60 | 61 | .TP 62 | \fB\-\-no\-proxy\fP, \fB\-N\fP 63 | Don't use any proxy server to download the file. Not possible when a 64 | transparent proxy is active somewhere, of course. 65 | 66 | .TP 67 | \fB\-\-verbose\fP 68 | If you want to see more status messages, you can use this option. Use it 69 | more than once if you want to see more. 70 | 71 | .TP 72 | \fB\-\-quiet\fP, \fB-q\fP 73 | No output to stdout. 74 | 75 | .TP 76 | \fB\-\-alternate\fP, \fB-a\fP 77 | This will show an alternate progress indicator. A bar displays the progress 78 | and status of the different threads, along with current speed and an 79 | estimate for the remaining download time. 80 | 81 | .TP 82 | \fB\-\-header=x\fP, \fB\-H\ x\fP 83 | Add an additional HTTP header. This option should be in the form "Header: 84 | Value". See RFC 2616 section 4.2 and 14 for details on the format and 85 | standardized headers. 86 | 87 | .TP 88 | \fB\-\-user-agent=x\fP, \fB\-U\ x\fP 89 | Set the HTTP user agent to use. Some websites serve different content based upon 90 | this parameter. The default value will include "Axel", its version and the 91 | platform. 92 | 93 | .TP 94 | \fB\-\-help\fP, \fB\-h\fP 95 | A brief summary of all the options. 96 | 97 | .TP 98 | \fB\-\-version\fP, \fB\-V\fP 99 | Get version information. 100 | 101 | .SH NOTE 102 | Long (double dash) options are supported only if your platform knows about 103 | the getopt_long call. If it does not (like *BSD), only the short options can 104 | be used. 105 | 106 | .SH RETURN VALUE 107 | The program returns 0 when the download was succesful, 1 if something really 108 | went wrong and 2 if the download was interrupted. If something else comes back, 109 | it must be a bug.. 110 | 111 | .SH EXAMPLES 112 | .nf 113 | axel ftp://ftp.{be,nl,uk,de}.kernel.org/pub/linux/kernel/v2.4/linux-2.4.17.tar.bz2 114 | .fi 115 | 116 | This will use the Belgian, Dutch, English and German kernel.org mirrors to 117 | download a Linux 2.4.17 kernel image. 118 | 119 | .nf 120 | axel \-S4 ftp://ftp.kernel.org/pub/linux/kernel/v2.4/linux-2.4.17.tar.bz2 121 | .fi 122 | 123 | This will do a search for the linux-2.4.17.tar.bz2 file on filesearching.com 124 | and it'll use the four (if possible) fastest mirrors for the download. 125 | (Possibly including ftp.kernel.org) 126 | 127 | (Of course, the commands are a single line, but they're too long to fit on 128 | one line in this page.) 129 | 130 | .SH FILES 131 | .PP 132 | \fI/etc/axelrc\fP System-wide configuration file.

That's why Axel 0.97 is a major redesign: All the 13 | downloading code is out of main() now. Writing your own downloader which 14 | uses Axel should not be too difficult now. 15 | 16 | This document contains basic instructions on how to write a program which 17 | uses the Axel >=0.97 code to download data. 18 | 19 | Some work needs to be done before I can convert axel into a library. I don't 20 | know whether I'll do it at all.. So this API description is only useful if 21 | you want to create an alternate interface for the program, at the moment. 22 | Later on, I might change this. A Perl port of Axel would be nice too. :-) 23 | 24 | 25 | /* The structures */ 26 | 27 | If you want to use Axel, you should have all the *.[ch] files in your 28 | program's directory (or subdir, whatever you want...) and include the axel.h 29 | file into your program. Then, the following structures and functions will be 30 | available: 31 | 32 | typedef struct 33 | { 34 | conn_t *conn; 35 | conf_t conf[1]; 36 | char filename[MAX_STRING]; 37 | double start_time; 38 | int next_state, finish_time; 39 | int bytes_done, start_byte, size; 40 | int bytes_per_second; 41 | int delay_time; 42 | int outfd; 43 | int ready; 44 | message_t *message; 45 | url_t *url; 46 | } axel_t; 47 | 48 | This is probably the most important structure.. Each axel structure can 49 | handle a separate download, each with a variable amount of connections. 50 | There is no maximum amount of connections hard-coded into the program 51 | anymore, by the way. The way conn_t and conf_t structures work is not very 52 | important for most people, it's mainly important for internal use. You /can/ 53 | use those structures, if you want, they're not that complex... 54 | 55 | The filename string is set correctly by axel_new(). If you want data to 56 | be put into a different file, you can change the variable /after/ calling 57 | axel_new(), and /before/ calling axel_open(). The string can also include 58 | a full pathname. 59 | 60 | start_time contains the time at which the download started. Not very 61 | interesting for you, probably. Neither should next_state be very important, 62 | it just contains the time at which the next state file should be saved. 63 | (State files are important for resuming support, as described in the README 64 | file..) finish_time might be interesting, though. It contains the estimated 65 | time at which the download should be finished. 66 | 67 | bytes_done contains the number of bytes downloaded for this file, size 68 | contains the total file size. start_byte should be zero, usually, unless 69 | you're resuming a download. 70 | 71 | The code also calculates the average speed. This speed is put in the 72 | bytes_per_second variable. 73 | 74 | delay_time is not interesting at all. It's just used for the code which 75 | tries to slow down the download. You shouldn't really touch outfd either, 76 | it contains the file descriptor of the local file. 77 | 78 | ready is set to non-zero as soon as all data is downloaded, or as soon as 79 | something goes wrong. You shouldn't call axel_do() anymore, when ready is 80 | set. 81 | 82 | Last but not least, message. This is a linked list of messages to the user. 83 | You, as the programmer, may decide what to do with them. You can just 84 | destroy them (don't just ignore them, the messages do eat memory!) or you 85 | can log/display them. The structure is very simple, and I hope this is clear 86 | enough: 87 | 88 | typedef struct { 89 | void *next; 90 | char text[MAX_STRING]; 91 | } message_t; 92 | 93 | Just don't forget to free() the message structures after printing them, and 94 | set axel->message to NULL to prevent crashes. See the print_messages() 95 | function in text.c for an example. 96 | 97 | message used to be the last, but I added url. It's a linked list as well, 98 | and in fact url_t == message_t. Not really of any importance, though. This 99 | element contains a number of URL's that'll be used by Axel for the download. 100 | The program can use multiple mirrors at the same time. This structure is 101 | filled in by axel_new, you shouldn't touch it yourself. 102 | 103 | 104 | /* The functions */ 105 | 106 | int conf_init( conf_t *conf ); 107 | 108 | Axel needs some settings. Your program has to allocate a conf_t structure 109 | and initialize it using this function. It sets some defaults, and then it 110 | scans your environment variables for some settings, and it tries to read 111 | a system-wide and personal user configuration file. 112 | 113 | axel_t *axel_new( conf_t *conf, char count, char *url ); 114 | axel_t *axel_new( conf_t *conf, char count, search_t *urls ); 115 | 116 | axel_new() allocates a new axel_t structure. You should pass a configuration 117 | structure and an URL. A pointer to a new axel_t structure will be returned. 118 | axel->filename is set now. You can change it, if you want data to be stored 119 | to a different file. Changing axel->filename after calling axel_open does 120 | not make sense, so be quick. :-) 121 | If you want axel to download from more than one mirror at once, you can use 122 | the second syntax. A search_t structure can be generated by the search_* 123 | functions. If you use the second syntax, count should contain the number of 124 | mirrors to be used from the structure. If you just want to pass a string 125 | with one URL (first syntax), count should be zero. Please note that all the 126 | mirrors passed to axel_new() should support acceleration. The support check 127 | should be done before downloading, which isn't much of a problem because 128 | search_getspeeds does it automatically. 129 | The ready element of the returned structure is set to one if nothing goes 130 | wrong. If it's zero, you shouldn't use the returned structure for anything 131 | else than displaying the error message(s) and closing it. 132 | 133 | int axel_open( axel_t *axel ); 134 | 135 | axel_open() opens a local file to store downloaded data. Returns non-zero if 136 | nothing goes wrong. If anything goes wrong, you should still call 137 | axel_close() to clean things up. This is not done automatically, so that you 138 | can read any message still left in the structure. 139 | 140 | void axel_start( axel_t *axel ); 141 | 142 | axel_start() starts the actual downloading. Normally, nothing should go 143 | wrong during this call, so it does not return anything. 144 | 145 | void axel_do( axel_t *axel ); 146 | 147 | axel_do() should be called regularly (ie as often as possible...) to handle 148 | any incoming data. You don't have to do anything else, all data is stored in 149 | the local file automatically. You should stop calling this one as soon as 150 | axel->ready is set. Or you can stop calling it yourself, that's possible. 151 | Just don't forget to call axel_close()! 152 | 153 | void axel_close( axel_t *axel ); 154 | 155 | If you want to stop downloading (ie if the download is complete) you should 156 | deallocate the axel_t structure using this function. Any connection still 157 | open will be closed and deallocated, all messages in the structure are 158 | deleted. You should always call this one when you're ready, if you don't 159 | want to waste memory. 160 | 161 | double gettime(); 162 | 163 | This one is just a 'bonus'... I use it myself in text.c and axel.c, so I 164 | decided to make it global. It just returns the actual time, but with more 165 | precision. 166 | 167 | 168 | /* filesearcher.com interface */ 169 | 170 | If you want to search for a faster mirror to download your file, or if you 171 | want to download from more than one server at once, you can use this 172 | interface. It's quite simple. You should create an array of this type: 173 | 174 | typedef struct 175 | { 176 | char url[MAX_STRING]; 177 | double speed_start_time; 178 | int speed, size; 179 | pthread_t speed_thread[1]; 180 | conf_t *conf; 181 | } search_t; 182 | 183 | And it's wise to memset() it to zero before you start, btw. You also have to 184 | set the conf pointer for the first index of the array. Other fields will 185 | be filled in by these functions: 186 | 187 | int search_makelist( search_t *results, char *url ); 188 | 189 | This function checks your URL, fetches the file size (needed for the search) 190 | and queries the ftpsearcher.com server for any mirror of this file. This one 191 | is finished in a few seconds on my system. It returns the number of mirrors 192 | found. Please note that, after calling this function, the first index of 193 | your search_t array contains the URL you used as an argument to this 194 | function. The speed field is filled in already for that one. 195 | 196 | int search_getspeeds( search_t *results, int count ); 197 | 198 | This is quite time consuming. It tries all the URL's from the list, and 199 | checks the speed. URL's which do not exist, or URL's on non-supported 200 | servers are marked as bad, they can't be used. This is more time-consuming 201 | than a simple ping (it takes about twenty seconds on my system, but it 202 | heavily depends on the connection and your settings), but it makes sure only 203 | usable URL's are passed to the downloader. The function returns the number 204 | of not-bad servers. 205 | 206 | void search_sortlist( search_t *results, int count ); 207 | 208 | It's very wise to sort the list of mirrors using this function before 209 | passing it to axel_new().

Beckers 52 | - Update manpages axel.1 and axel-kapt.1 53 | - Prevent crash and raise error if FTP CWD fails 54 | - Prevent crash on long URLs and increase max length of URL to 1024 55 | - Fix segfaults on HTTP404 and HTTP401 responses 56 | 57 | Finished Jan 18 2008 58 | 59 | Version 1.0b: 60 | - Removed spaces between -S[x] in man-pages, etc. They mess things up. 61 | - Fixed configure for OpenBSD. 62 | - Fixed configuration bug: s/alternate_interface/alternate_output/ in 63 | axelrc.example, thanks to CLOTILDE Guy Daniel for the bug report! 64 | - Fixed weird behaviour when downloading from an unsupported server. 65 | - Fixed buffer overflow in conn.c. (CAN-2005-0390) 66 | 67 | Finished Apr 06 2005 68 | 69 | 70 | Version 1.0a: 71 | - gstrip on Solaris/SPARC breaks the binary, so stripping is made optional 72 | (but enabled by default!) and /usr/ccs/bin/strip is used instead of 73 | gstrip. 74 | - Fixed a small (not harmful) errorcode interpretation bug in the ftp_size 75 | code. 76 | - Downloading from unsupported sites works better now. 77 | - Added support for downloading using more than one local network interface. 78 | - Fixed a potential SIGSEGV bug. Would only happen with about more than 64 79 | connections usually. Still strange things can happen with too many 80 | connections when using Linux.. 81 | - Hopefully fixed the problem with downloading from forwarding URL's. 82 | - HTTP %-escapes are handled now. 83 | - Alternate progress indicator with estimation of remaining download time 84 | - Changed the return-code a bit, see man-page for details. 85 | 86 | Finished Feb 19 2002 87 | 88 | 89 | Version 1.0: 90 | - Fixed a reconnect problem: Check for stalled connections was skipped by 91 | previous versions if there is no active connection. 92 | - Solaris does not have www in /etc/services which confused Axel. Fixed. 93 | - Created a new build system. 94 | - install utility not used anymore: Solaris' install does weird things. 95 | - Added support for Cygwin and Solaris. 96 | - Corrected a little problem in de.po. 97 | - Thrown out the packaging stuff. 98 | 99 | Finished Dec 6 2001 100 | 101 | 102 | Version 0.99b brings you: 103 | - Debian package bugfix. 104 | - Restored i18n support. 105 | 106 | Finished Nov 16 2001 107 | 108 | 109 | Version 0.99a brings you: 110 | - Small bugfix for dumb HTTP bug. 111 | 112 | Finished Nov 10 2001 113 | 114 | 115 | Version 0.99 brings you: 116 | - Improved speed limiter. (For low speeds a smaller buffer works better, 117 | so the buffer is resized automatically for low speeds.) 118 | - Some FTP servers don't ask for a password which confused ftp.c. Fixed. 119 | - Some HTTP servers send chunked data when using HTTP/1.1. So I went back 120 | to HTTP/1.0.. (This also fixes the occasional filesearching.com problem) 121 | - Even more problems with FTP server reply codes, but they must be fixed 122 | now, Axel's RFC compliant. 123 | - For HTTP downloads a Range: header is not sent when downloading starting 124 | at byte 0. This is just a work-around for a problem with a weird webserver 125 | which sends corrupted data when a Range: header is sent. It's just a 126 | work-around for a rare problem, it does not really fix anything. 127 | - RPM package for axel-kapt added. 128 | 129 | Finished Nov 9 2001 130 | 131 | 132 | Version 0.98 brings you: 133 | - Fixed the weird percentage indicator bug. (Was buggy for large files, 134 | did not affect the downloaded data.) 135 | - For single connection downloads from Apache: Apache returns a 200 result 136 | code when the specified file range is the complete file. Axel handles 137 | this correctly now. 138 | - Roxen FTP servers return the address and port number without brackets 139 | after a passive command. This is RFC-compliant but quite unique. But now 140 | handled correctly. 141 | - Fixed some things to make it work on Darwin again. 142 | - 'Upgraded' HTTP requests to HTTP/1.1. Tried this to fix a download 143 | corruption bug for downloads from archive.progeny.com, but it did not 144 | work. wget's resume has exactly the same problem. But using HTTP/1.1 is 145 | more compliant (because in fact HTTP/1.0 does not support Ranges) so I'll 146 | keep it this way.. 147 | - Previous version used to delete the statefile in some cases. Fixed. 148 | 149 | Finished Nov 3 2001 150 | 151 | 152 | Version 0.97 (Bitcrusher) brings you: 153 | - Major redesign: Moved a lot of code from main() to separate functions, 154 | it should make it easier to create different interfaces for the program. 155 | - All those ifdefs were a mess, they don't exist anymore. Separate threads 156 | for setting up connections are used by default now. Version 0.96 will not 157 | disappear, by the way. 158 | - HTTP HEAD request not used anymore: Squid's headers are incorrect when 159 | using the HEAD request. 160 | - conn_disconnect did not work for FTP connections through HTTP proxies. 161 | - Documentation fix, sort of: The example configuration file still said 162 | proxies are unsupported. But they are supported for quite some time 163 | already. 164 | - Wrote a small (Small? Larger than any other doc.. :-) description of the 165 | Axel API. 166 | - Added finish_time code. (Credits to sjoerd@huiswerkservice.nl) 167 | - Calling conn_setup without calling conn_init first also works when using 168 | a proxy now. 169 | - A client for filesearching.com. You can use it to search for mirrors and 170 | download from more than mirror at once. 171 | - Fixed another segfault bug which did not show up on my own system... 172 | Also fixed by 0.96a. 173 | - Global error string is gone. Unusable in threaded programs. 174 | - The -V switch stopped working some time ago because I forgot to put it 175 | in the getopt string. Now it's back, alive and kickin'... 176 | - TYPE I should be done quite early. Some servers return weird file sizes 177 | when still in ASCII mode. 178 | - ftp.c (ftp_wait) sometimes resized conn->message to below MAX_STRING 179 | which is Not Good(tm). 180 | - I18N support is a bit broken at this time, it'll be fixed later. 181 | - Tidied up the man-page a bit. 182 | - Removed config.h file, -D flags used again. 183 | - Added axel-kapt interface. 184 | - Changed syntax: Local file must be specified using the -o option now. 185 | This allows the user to specify more than one URL and all of them will 186 | be used for the download. A local directory can be passed as well, the 187 | program will append the correct filename. 188 | - Fixed a bug which caused the program not to be able to download files 189 | for which only one byte has to be downloaded for one of the connections. 190 | - Why bitcrusher? Just because I liked to have a code name for this 191 | release... Bit crusher is a name of a musical group here in the 192 | Netherlands, and it's a nice name for a downloader as well, I hope... 193 | 194 | Finished Oct 25 2001 195 | 196 | 197 | Version 0.96 brings you: 198 | - Fixed a terrible bug which caused any FTP download to corrupt. I promise 199 | I will test the program before any next release. :-(( HTTP did work in 200 | 0.95. 201 | 202 | Finished Aug 14 2001 (Why is this fix so late? Because the actual release 203 | of version 0.95 was only last Friday/Saturday...) 204 | 205 | And yes, I tested it now. It works now. HTTP and FTP. 206 | 207 | 208 | Version 0.95 brings you: 209 | - An important bugfix: When bringing up the connection failed, the program 210 | used to be unable to reconnect. :( 211 | - Small changes to make the program compile on FreeBSD and Darwin. 212 | - Support check for FTP servers is done only once now. 213 | - SIZE command is really used now. 214 | - Fixed a SIGINT-does-not-abort problem. Btw: Ctrl-\ (SIGQUIT) always works! 215 | - Connection status messages are not displayed by default. You can enable 216 | them with the verbose-option. 217 | 218 | Finished Aug 7 2001 219 | 220 | 221 | Version 0.94 brings you: 222 | - 'make install' uses install instead of mkdir/cp now. 223 | - Added 'make uninstall' option. 224 | - Added more explanations to axelrc.example. 225 | - It uses the HTTP HEAD request now. Didn't know that one before. :) 226 | - Debian packaging stuff and RPM .spec file included by default. 227 | - select() problem now really understood... The real point was, that 228 | sometimes select() was called with an empty fd set. Now I solved the 229 | problem in a more 'useful' way. 230 | 231 | Finished Jun 26 2001 232 | 233 | 234 | Version 0.93 brings you: 235 | - A compile-time option to remove all the multi-connection stuff. Program 236 | works without state files then, and it's a bit smaller, just in case you 237 | need a very small program and if you don't believe in acceleration. :) 238 | - The SIZE command is now used as long as the URL does not contain wildcards. 239 | Because FTP servers are just too different. :( 240 | - You can do FTP downloads through HTTP proxies now. 241 | - The weird initial 1-second delay which happened sometimes does not exist 242 | anymore: It was because of select(), which does not return immediately 243 | if there's data on a socket before the call starts. My first solution 244 | is using a lower timeout, I hope there's a better solution available... 245 | - Local file existence check. 246 | - Small bug fixed in conf.c. 247 | 248 | Finished May 22 2001 249 | 250 | 251 | Version 0.92 brings you: 252 | - A credits file!! ;) 253 | - A German translation. Herrman J. Beckers: Thanks a lot! 254 | - ftp.c should understand weird Macintosh FTP servers too, now. 255 | - Connections are initialized in a different thread because then the program 256 | can go on downloading data from other connections while setting up. Quick 257 | hack, but it works. 258 | - config.h contains the configuration definitions now. 259 | - A URL - can be specified. The program will read a URL from stdin. Might 260 | be useful if you don't want other people to see the URL in the 'ps aux' 261 | output. (Think about passwords in URLs...) 262 | 263 | Finished May 11 2001 264 | 265 | 266 | Version 0.91 brings you: 267 | - A man page. 268 | - A quiet mode. 269 | - A Debian package. (0.9 .deb exists too, but that was after the 'official' 270 | 0.9 release..) 271 | - Made the sizes/times displayed after downloading more human-readable. 272 | - Corrected some stupid things in the nl.po file. 273 | - No bug in ftp_wait anymore, (or at least one bug less ;) the program was a 274 | bit too late with the realloc() sometimes. I just hate those multi-line 275 | replies.. :( 276 | - HTTP proxy support. no_proxy configuration flag also in use. 277 | - Support for empty configuration strings. 278 | - URL parser understands wrongly formatted URLs like slashdot.org. (instead 279 | of the correct http://slashdot.org/) 280 | 281 | Finished Apr 30 2001 282 | 283 | 284 | Version 0.9 brings you: 285 | - See the README for all the old features. 286 | - Internationalization support. 287 | - Clearer error messages. 288 | - Probably some bug fixes too. 289 | - A highly sophisticated Makefile.. ;) 290 | 291 | Finished Apr 22 2001 292 | -------------------------------------------------------------------------------- /text.c: -------------------------------------------------------------------------------- 1 | /********************************************************************\ 2 | * Axel -- A lighter download accelerator for Linux and other Unices. * 3 | * * 4 | * Copyright 2001 Wilmer van der Gaast * 5 | \********************************************************************/ 6 | 7 | /* Text interface */ 8 | 9 | /* 10 | This program is free software; you can redistribute it and/or modify 11 | it under the terms of the GNU General Public License as published by 12 | the Free Software Foundation; either version 2 of the License, or 13 | (at your option) any later version. 14 | 15 | This program is distributed in the hope that it will be useful, 16 | but WITHOUT ANY WARRANTY; without even the implied warranty of 17 | MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

By contrast, the GNU General Public 13 | License is intended to guarantee your freedom to share and change free 14 | software--to make sure the software is free for all its users. This 15 | General Public License applies to most of the Free Software 16 | Foundation's software and to any other program whose authors commit to 17 | using it. (Some other Free Software Foundation software is covered by 18 | the GNU Lesser General Public License instead.) You can apply it to 19 | your programs, too. 20 | 21 | When we speak of free software, we are referring to freedom, not 22 | price. Our General Public Licenses are designed to make sure that you 23 | have the freedom to distribute copies of free software (and charge for 24 | this service if you wish), that you receive source code or can get it 25 | if you want it, that you can change the software or use pieces of it 26 | in new free programs; and that you know you can do these things. 27 | 28 | To protect your rights, we need to make restrictions that forbid 29 | anyone to deny you these rights or to ask you to surrender the rights. 30 | These restrictions translate to certain responsibilities for you if you 31 | distribute copies of the software, or if you modify it. 32 | 33 | For example, if you distribute copies of such a program, whether 34 | gratis or for a fee, you must give the recipients all the rights that 35 | you have. You must make sure that they, too, receive or can get the 36 | source code. And you must show them these terms so they know their 37 | rights. 38 | 39 | We protect your rights with two steps: (1) copyright the software, and 40 | (2) offer you this license which gives you legal permission to copy, 41 | distribute and/or modify the software. 42 | 43 | Also, for each author's protection and ours, we want to make certain 44 | that everyone understands that there is no warranty for this free 45 | software. If the software is modified by someone else and passed on, we 46 | want its recipients to know that what they have is not the original, so 47 | that any problems introduced by others will not reflect on the original 48 | authors' reputations. 49 | 50 | Finally, any free program is threatened constantly by software 51 | patents. We wish to avoid the danger that redistributors of a free 52 | program will individually obtain patent licenses, in effect making the 53 | program proprietary. To prevent this, we have made it clear that any 54 | patent must be licensed for everyone's free use or not licensed at all. 55 | 56 | The precise terms and conditions for copying, distribution and 57 | modification follow. 58 | 59 | GNU GENERAL PUBLIC LICENSE 60 | TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION 61 | 62 | 0. This License applies to any program or other work which contains 63 | a notice placed by the copyright holder saying it may be distributed 64 | under the terms of this General Public License. The "Program", below, 65 | refers to any such program or work, and a "work based on the Program" 66 | means either the Program or any derivative work under copyright law: 67 | that is to say, a work containing the Program or a portion of it, 68 | either verbatim or with modifications and/or translated into another 69 | language. (Hereinafter, translation is included without limitation in 70 | the term "modification".) Each licensee is addressed as "you". 71 | 72 | Activities other than copying, distribution and modification are not 73 | covered by this License; they are outside its scope. The act of 74 | running the Program is not restricted, and the output from the Program 75 | is covered only if its contents constitute a work based on the 76 | Program (independent of having been made by running the Program). 77 | Whether that is true depends on what the Program does. 78 | 79 | 1. You may copy and distribute verbatim copies of the Program's 80 | source code as you receive it, in any medium, provided that you 81 | conspicuously and appropriately publish on each copy an appropriate 82 | copyright notice and disclaimer of warranty; keep intact all the 83 | notices that refer to this License and to the absence of any warranty; 84 | and give any other recipients of the Program a copy of this License 85 | along with the Program. 86 | 87 | You may charge a fee for the physical act of transferring a copy, and 88 | you may at your option offer warranty protection in exchange for a fee. 89 | 90 | 2. You may modify your copy or copies of the Program or any portion 91 | of it, thus forming a work based on the Program, and copy and 92 | distribute such modifications or work under the terms of Section 1 93 | above, provided that you also meet all of these conditions: 94 | 95 | a) You must cause the modified files to carry prominent notices 96 | stating that you changed the files and the date of any change. 97 | 98 | b) You must cause any work that you distribute or publish, that in 99 | whole or in part contains or is derived from the Program or any 100 | part thereof, to be licensed as a whole at no charge to all third 101 | parties under the terms of this License. 102 | 103 | c) If the modified program normally reads commands interactively 104 | when run, you must cause it, when started running for such 105 | interactive use in the most ordinary way, to print or display an 106 | announcement including an appropriate copyright notice and a 107 | notice that there is no warranty (or else, saying that you provide 108 | a warranty) and that users may redistribute the program under 109 | these conditions, and telling the user how to view a copy of this 110 | License. (Exception: if the Program itself is interactive but 111 | does not normally print such an announcement, your work based on 112 | the Program is not required to print an announcement.) 113 | 114 | These requirements apply to the modified work as a whole. If 115 | identifiable sections of that work are not derived from the Program, 116 | and can be reasonably considered independent and separate works in 117 | themselves, then this License, and its terms, do not apply to those 118 | sections when you distribute them as separate works. But when you 119 | distribute the same sections as part of a whole which is a work based 120 | on the Program, the distribution of the whole must be on the terms of 121 | this License, whose permissions for other licensees extend to the 122 | entire whole, and thus to each and every part regardless of who wrote it. 123 | 124 | Thus, it is not the intent of this section to claim rights or contest 125 | your rights to work written entirely by you; rather, the intent is to 126 | exercise the right to control the distribution of derivative or 127 | collective works based on the Program. 128 | 129 | In addition, mere aggregation of another work not based on the Program 130 | with the Program (or with a work based on the Program) on a volume of 131 | a storage or distribution medium does not bring the other work under 132 | the scope of this License. 133 | 134 | 3. You may copy and distribute the Program (or a work based on it, 135 | under Section 2) in object code or executable form under the terms of 136 | Sections 1 and 2 above provided that you also do one of the following: 137 | 138 | a) Accompany it with the complete corresponding machine-readable 139 | source code, which must be distributed under the terms of Sections 140 | 1 and 2 above on a medium customarily used for software interchange; or, 141 | 142 | b) Accompany it with a written offer, valid for at least three 143 | years, to give any third party, for a charge no more than your 144 | cost of physically performing source distribution, a complete 145 | machine-readable copy of the corresponding source code, to be 146 | distributed under the terms of Sections 1 and 2 above on a medium 147 | customarily used for software interchange; or, 148 | 149 | c) Accompany it with the information you received as to the offer 150 | to distribute corresponding source code. (This alternative is 151 | allowed only for noncommercial distribution and only if you 152 | received the program in object code or executable form with such 153 | an offer, in accord with Subsection b above.) 154 | 155 | The source code for a work means the preferred form of the work for 156 | making modifications to it. For an executable work, complete source 157 | code means all the source code for all modules it contains, plus any 158 | associated interface definition files, plus the scripts used to 159 | control compilation and installation of the executable. However, as a 160 | special exception, the source code distributed need not include 161 | anything that is normally distributed (in either source or binary 162 | form) with the major components (compiler, kernel, and so on) of the 163 | operating system on which the executable runs, unless that component 164 | itself accompanies the executable. 165 | 166 | If distribution of executable or object code is made by offering 167 | access to copy from a designated place, then offering equivalent 168 | access to copy the source code from the same place counts as 169 | distribution of the source code, even though third parties are not 170 | compelled to copy the source along with the object code. 171 | 172 | 4. You may not copy, modify, sublicense, or distribute the Program 173 | except as expressly provided under this License. Any attempt 174 | otherwise to copy, modify, sublicense or distribute the Program is 175 | void, and will automatically terminate your rights under this License. 176 | However, parties who have received copies, or rights, from you under 177 | this License will not have their licenses terminated so long as such 178 | parties remain in full compliance. 179 | 180 | 5. You are not required to accept this License, since you have not 181 | signed it. However, nothing else grants you permission to modify or 182 | distribute the Program or its derivative works. These actions are 183 | prohibited by law if you do not accept this License. Therefore, by 184 | modifying or distributing the Program (or any work based on the 185 | Program), you indicate your acceptance of this License to do so, and 186 | all its terms and conditions for copying, distributing or modifying 187 | the Program or works based on it. 188 | 189 | 6. Each time you redistribute the Program (or any work based on the 190 | Program), the recipient automatically receives a license from the 191 | original licensor to copy, distribute or modify the Program subject to 192 | these terms and conditions. You may not impose any further 193 | restrictions on the recipients' exercise of the rights granted herein. 194 | You are not responsible for enforcing compliance by third parties to 195 | this License. 196 | 197 | 7. If, as a consequence of a court judgment or allegation of patent 198 | infringement or for any other reason (not limited to patent issues), 199 | conditions are imposed on you (whether by court order, agreement or 200 | otherwise) that contradict the conditions of this License, they do not 201 | excuse you from the conditions of this License. If you cannot 202 | distribute so as to satisfy simultaneously your obligations under this 203 | License and any other pertinent obligations, then as a consequence you 204 | may not distribute the Program at all. For example, if a patent 205 | license would not permit royalty-free redistribution of the Program by 206 | all those who receive copies directly or indirectly through you, then 207 | the only way you could satisfy both it and this License would be to 208 | refrain entirely from distribution of the Program. 209 | 210 | If any portion of this section is held invalid or unenforceable under 211 | any particular circumstance, the balance of the section is intended to 212 | apply and the section as a whole is intended to apply in other 213 | circumstances. 214 | 215 | It is not the purpose of this section to induce you to infringe any 216 | patents or other property right claims or to contest validity of any 217 | such claims; this section has the sole purpose of protecting the 218 | integrity of the free software distribution system, which is 219 | implemented by public license practices. Many people have made 220 | generous contributions to the wide range of software distributed 221 | through that system in reliance on consistent application of that 222 | system; it is up to the author/donor to decide if he or she is willing 223 | to distribute software through any other system and a licensee cannot 224 | impose that choice. 225 | 226 | This section is intended to make thoroughly clear what is believed to 227 | be a consequence of the rest of this License. 228 | 229 | 8. If the distribution and/or use of the Program is restricted in 230 | certain countries either by patents or by copyrighted interfaces, the 231 | original copyright holder who places the Program under this License 232 | may add an explicit geographical distribution limitation excluding 233 | those countries, so that distribution is permitted only in or among 234 | countries not thus excluded. In such case, this License incorporates 235 | the limitation as if written in the body of this License. 236 | 237 | 9. The Free Software Foundation may publish revised and/or new versions 238 | of the General Public License from time to time. Such new versions will 239 | be similar in spirit to the present version, but may differ in detail to 240 | address new problems or concerns. 241 | 242 | Each version is given a distinguishing version number. If the Program 243 | specifies a version number of this License which applies to it and "any 244 | later version", you have the option of following the terms and conditions 245 | either of that version or of any later version published by the Free 246 | Software Foundation. If the Program does not specify a version number of 247 | this License, you may choose any version ever published by the Free Software 248 | Foundation. 249 | 250 | 10. If you wish to incorporate parts of the Program into other free 251 | programs whose distribution conditions are different, write to the author 252 | to ask for permission. For software which is copyrighted by the Free 253 | Software Foundation, write to the Free Software Foundation; we sometimes 254 | make exceptions for this. Our decision will be guided by the two goals 255 | of preserving the free status of all derivatives of our free software and 256 | of promoting the sharing and reuse of software generally. 257 | 258 | NO WARRANTY 259 | 260 | 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY 261 | FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN 262 | OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES 263 | PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED 264 | OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF 265 | MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.
