When I write this, there are 16500 lines of source - code, and by the time you read this it has probably grown even more. - - Of course there are lots of bugs left. And lots of misfeatures. - - To help us make curl the stable and solid product we want it to be, we need - bug reports and bug fixes. If you can't fix a bug yourself and submit a fix - for it, try to report an as detailed report as possible to the curl mailing - list to allow one of us to have a go at a solution. You should also post - your bug/problem at curl's bug tracking system over at - - http://sourceforge.net/bugs/?group_id=976 - - When reporting a bug, you should include information that will help us - understand what's wrong, what's expected and how to repeat it. You therefore - need to supply your operating system's name and version number (uname -a - under a unix is fine), what version of curl you're using (curl -v is fine), - what URL you were working with and anything else you think matters. - - If curl crashed, causing a core dump (in unix), there is hardly any use to - send that huge file to anyone of us. Unless we have an exact same system - setup as you, we can't do much with it. What we instead ask of you is to get - a stack trace and send that (much smaller) output to us instead! - - The address and how to subscribe to the mailing list is detailed in the - README.curl file. - - HOW TO GET A STACK TRACE with a common unix debugger - ==================================================== - - First, you must make sure that you compile all sources with -g and that you - don't 'strip' the final executable. - - Run the program until it bangs. - - Run your debugger on the core file, like '<debugger> curl core'. <debugger> - should be replaced with the name of your debugger, in most cases that will - be 'gdb', but 'dbx' and others also occur. - - When the debugger has finished loading the core file and presents you a - prompt, you can give the compiler instructions. Enter 'where' (without the - quotes) and press return. - - The list that is presented is the stack trace. If everything worked, it is - supposed to contain the chain of functions that were called when curl - crashed. - diff --git a/CONTRIBUTE b/CONTRIBUTE deleted file mode 100644 index 99cf2c53e..000000000 --- a/CONTRIBUTE +++ /dev/null @@ -1,74 +0,0 @@ - _ _ ____ _ - ___| | | | _ \| | - / __| | | | |_) | | - | (__| |_| | _ <| |___ - \___|\___/|_| \_\_____| - -CONTRIBUTE - -To Think About When Contributing Source Code - - This document is intended to offer some guidelines that can be useful to - keep in mind when you decide to write a contribution to the project. This - concerns new features as well as corrections to existing flaws or bugs. - -Naming - - Try using a non-confusing naming scheme for your new functions and variable - names. It doesn't necessarily have to mean that you should use the same as - in other places of the code, just that the names should be logical, - understandable and be named according to what they're used for. - -Indenting - - Please try using the same indenting levels and bracing method as all the - other code already does. It makes the source code a lot easier to follow if - all of it is written using the same style. I don't ask you to like it, I - just ask you to follow the tradition! ;-) - -Commenting - - Comment your source code extensively. I don't see myself as a very good - source commenter, but I try to become one. Commented code is quality code - and enables future modifications much more. Uncommented code much more risk - being completely replaced when someone wants to extend things, since other - persons' source code can get quite hard to read. - -General Style - - Keep your functions small. If they're small you avoid a lot of mistakes and - you don't accidentally mix up variables. - -Non-clobbering All Over - - When you write new functionality or fix bugs, it is important that you - don't fiddle all over the source files and functions. Remember that it is - likely that other people have done changes in the same source files as you - have and possibly even in the same functions. If you bring completely new - functionality, try writing it in a new source file. If you fix bugs, try to - fix one bug at a time and send them as separate patches. - -Separate Patches Doing Different Things - - It is annoying when you get a huge patch from someone that is said to fix 511 - odd problems, but discussions and opinions don't agree with 510 of them - or - 509 of them were already fixed in a different way. Then the patcher needs to - extract the single interesting patch from somewhere within the huge pile of - source, and that gives a lot of extra work. Preferably, all fixes that - correct different problems should be in their own patch with an attached - description exactly what they correct so that all patches can be selectively - applied by the maintainer or other interested parties. - -Document - - Writing docs is dead boring and one of the big problems with many open - source projects. Someone's gotta do it. It makes it a lot easier if you - submit a small description of your fix or your new features with every - contribution so that it can be swiftly added to the package documentation. - -Write Access to CVS Repository - - If you are a frequent contributor, or have another good reason, you can of - course get write access to the CVS repository and then you'll be able to - check-in all your changes straight into the CVS tree instead of sending all - changes by mail as patches. Just ask if this is what you'd want. @@ -1,85 +0,0 @@ - _ _ ____ _ - ___| | | | _ \| | - / __| | | | |_) | | - | (__| |_| | _ <| |___ - \___|\___/|_| \_\_____| - -FAQ - -Problems connecting to SSL servers. -=================================== - - It took a very long time before I could sort out why curl had problems - to connect to certain SSL servers when using SSLeay or OpenSSL v0.9+. - The error sometimes showed up similar to: - - 16570:error:1407D071:SSL routines:SSL2_READ:bad mac decode:s2_pkt.c:233: - - It turned out to be because many older SSL servers don't deal with SSLv3 - requests properly.

Both ways on FTP, download ways on HTTP. - -Is libcurl thread safe? -======================= - - Yes, as far as curl's own code goes. It does use system calls that often - aren't thread safe in most environments, such as gethostbyname(). - - I am very interested in once and for all getting some kind of report or - README file from those who have used libcurl in a threaded environment, - since I haven't and I get this question more and more frequently! - -Why doesn't my posting using -F work? -===================================== - - You can't simply use -F or -d at your choice. The web server that will - receive your post assumes one of the formats. If the form you're trying to - "fake" sets the type to 'multipart/form-data', than and only then you must - use the -F type. In all the most common cases, you should use -d which then - causes a posting with the type 'application/x-www-form-urlencoded'. - -Does curl support custom FTP commands? -====================================== - - Yes it does, you can tell curl to perform optional commands both before - and/or after a file transfer. Study the -Q/--quote option. - - Since curl is used for file transfers, you don't use curl to just perform - ftp commands without transfering anything. Therefore you must always specify - a URL to transfer to/from even when doing custom FTP commands. - -Does curl work with other SSL libraries? -======================================== - - Curl has been written to use OpenSSL, although I doubt there would be much - problems using a different library. I just don't know any other free one and - that has limited my possibilities to develop against anything else. - - If anyone does "port" curl to use a commercial SSL library, I am of course - very interested in getting the patch! - -configre doesn't find OpenSSL even when it is installed -======================================================= - - Platforms: Solaris (native cc compiler) and HPUX (native cc compiler) - - When configuring curl, I specify --with-ssl.

The four most notable details are: - - 1. Different function names for close(), read(), write() - 2. Windows requires a couple of init calls - 3. The file descriptors for network communication and file operations are - not easily interchangable as in unix - 4. When writing data to stdout, Windows makes end-of-lines the DOS way, thus - destroying binary data, although you do want that conversion if it is - text coming through... (sigh) - - In curl, (1) and (2) are done with defines and macros, so that the source - looks the same at all places except for the header file that defines them. - - (3) is simply avoided by not trying any funny tricks on file descriptors. - - (4) is left alone, giving windows users problems when they pipe binary data - through stdout... - - Inside the source code, I do make an effort to avoid '#ifdef WIN32'. All - conditionals that deal with features *should* instead be in the format - '#ifdef HAVE_THAT_WEIRD_FUNCTION'.

All of those functions are - rather small and easy-to-follow, accept the one single and do-it-all named - curl_urlget() (entry point in lib/url.c). - - curl_urlget() takes a variable amount of arguments, and they must all be - passed in pairs, the parameter-ID and the parameter-value. The list of - arguments must be ended with a end-of-arguments parameter-ID. - - The function then continues to analyze the URL, get the different components - and connects to the remote host. This may involve using a proxy and/or using - SSL. The GetHost() function in lib/hostip.c is used for looking up host - names. - - When connected, the proper function is called. The functions are named after - the protocols they handle. ftp(), http(), dict(), etc. They all reside in - their respective files (ftp.c, http.c and dict.c). - - The protocol-specific functions deal with protocol-specific negotiations and - setup. They have access to the sendf() (from lib/sendf.c) function to send - printf-style formatted data to the remote host and when they're ready to make - the actual file transfer they call the Transfer() function (in - lib/download.c) to do the transfer. All printf()-style functions use the - supplied clones in lib/mprintf.c. - - While transfering, the progress functions in lib/progress.c are called at a - frequent interval. The speedcheck functions in lib/speedcheck.c are also used - to verify that the transfer is as fast as required. - - When the operation is done, the writeout() function in lib/writeout.c may be - called to report about the operation as specified previously in the arguments - to curl_urlget(). - - HTTP(S) - - HTTP offers a lot and is the protocol in curl that uses the most lines of - code. There is a special file (lib/formdata.c) that offers all the multipart - post functions. - - base64-functions for user+password stuff is in (lib/base64.c) and all - functions for parsing and sending cookies are found in - (lib/cookie.c). - - HTTPS uses in almost every means the same procedure as HTTP, with only two - exceptions: the connect procedure is different and the function used - - FTP - - The if2ip() function can be used for getting the IP number of a specified - network interface, and it resides in lib/if2ip.c - - TELNET - - Telnet is implemented in lib/telnet.c. - - FILE - - The file:// protocol is dealt with in lib/file.c. - - LDAP - - Everything LDAP is in lib/ldap.c. - - GENERAL - - URL encoding and decoding, called escaping and unescaping in the source code, - is found in lib/escape.c. - - While transfering data in Transfer() a few functions might get - used. get_date() in lib/getdate.c is for HTTP date comparisons. - - lib/getenv.c is for reading environment variables in a neat platform - independent way.

The reason for this - is simply that proxies are seldomly configured to allow this and that no - author has supplied code that makes it possible! - - HTTP - - Upload all data on stdin to a specified http site: - - curl -t http://www.upload.com/myfile - - Note that the http server must've been configured to accept PUT before this - can be done successfully. - - For other ways to do http data upload, see the POST section below. - -VERBOSE / DEBUG - - If curl fails where it isn't supposed to, if the servers don't let you - in, if you can't understand the responses: use the -v flag to get VERBOSE - fetching. Curl will output lots of info and all data it sends and - receives in order to let the user see all client-server interaction. - - curl -v ftp://ftp.upload.com/ - -DETAILED INFORMATION - - Different protocols provide different ways of getting detailed information - about specific files/documents. To get curl to show detailed information - about a single file, you should use -I/--head option. It displays all - available info on a single file for HTTP and FTP. The HTTP information is a - lot more extensive. - - For HTTP, you can get the header information (the same as -I would show) - shown before the data by using -i/--include. Curl understands the - -D/--dump-header option when getting files from both FTP and HTTP, and it - will then store the headers in the specified file. - - Store the HTTP headers in a separate file: - - curl --dump-header headers.txt curl.haxx.nu - - Note that headers stored in a separate file can be very useful at a later - time if you want curl to use cookies sent by the server. More about that in - the cookies section. - -POST (HTTP) - - It's easy to post data using curl. This is done using the -d <data> - option. The post data must be urlencoded. - - Post a simple "name" and "phone" guestbook. - - curl -d "name=Rafael%20Sagula&phone=3320780" \ - http://www.where.com/guest.cgi - - How to post a form with curl, lesson #1: - - Dig out all the <input> tags in the form that you want to fill in. (There's - a perl program called formfind.pl on the curl site that helps with this). - - If there's a "normal" post, you use -d to post. -d takes a full "post - string", which is in the format - - <variable1>=<data1>&<variable2>=<data2>&... - - The 'variable' names are the names set with "name=" in the <input> tags, and - the data is the contents you want to fill in for the inputs. The data *must* - be properly URL encoded. That means you replace space with + and that you - write weird letters with %XX where XX is the hexadecimal representation of - the letter's ASCII code. - - Example: - - (page located at http://www.formpost.com/getthis/ - - <form action="post.cgi" method="post"> - <input name=user size=10> - <input name=pass type=password size=10> - <input name=id type=hidden value="blablabla"> - <input name=ding value="submit"> - </form> - - We want to enter user 'foobar' with password '12345'. - - To post to this, you enter a curl command line like: - - curl -d "user=foobar&pass=12345&id=blablabla&dig=submit" (continues) - http://www.formpost.com/getthis/post.cgi - - - While -d uses the application/x-www-form-urlencoded mime-type, generally - understood by CGI's and similar, curl also supports the more capable - multipart/form-data type. This latter type supports things like file upload. - - -F accepts parameters like -F "name=contents". If you want the contents to - be read from a file, use <@filename> as contents. When specifying a file, - you can also specify which content type the file is, by appending - ';type=<mime type>' to the file name. You can also post contents of several - files in one field. So that the field name 'coolfiles' can be sent three - files with different content types in a manner similar to: - - curl -F "coolfiles=@fil1.gif;type=image/gif,fil2.txt,fil3.html" \ - http://www.post.com/postit.cgi - - If content-type is not specified, curl will try to guess from the extension - (it only knows a few), or use the previously specified type (from an earlier - file if several files are specified in a list) or finally using the default - type 'text/plain'. - - Emulate a fill-in form with -F. Let's say you fill in three fields in a - form. One field is a file name which to post, one field is your name and one - field is a file description. We want to post the file we have written named - "cooltext.txt". To let curl do the posting of this data instead of your - favourite browser, you have to check out the HTML of the form page to get to - know the names of the input fields. In our example, the input field names are - 'file', 'yourname' and 'filedescription'. - - curl -F "file=@cooltext.txt" -F "yourname=Daniel" \ - -F "filedescription=Cool text file with cool text inside" \ - http://www.post.com/postit.cgi - - So, to send two files in one post you can do it in two ways: - - 1. Send multiple files in a single "field" with a single field name: - - curl -F "pictures=@dog.gif,cat.gif" - - 2. Send two fields with two field names: - - curl -F "docpicture=@dog.gif" -F "catpicture=@cat.gif" - -REFERER - - A HTTP request has the option to include information about which address - that referred to actual page, and curl allows the user to specify that - referrer to get specified on the command line. It is especially useful to - fool or trick stupid servers or CGI scripts that rely on that information - being available or contain certain data. - - curl -e www.coolsite.com http://www.showme.com/ - -USER AGENT - - A HTTP request has the option to include information about the browser - that generated the request. Curl allows it to be specified on the command - line. It is especially useful to fool or trick stupid servers or CGI - scripts that only accept certain browsers. - - Example: - - curl -A 'Mozilla/3.0 (Win95; I)' http://www.nationsbank.com/ - - Other common strings: - 'Mozilla/3.0 (Win95; I)' Netscape Version 3 for Windows 95 - 'Mozilla/3.04 (Win95; U)' Netscape Version 3 for Windows 95 - 'Mozilla/2.02 (OS/2; U)' Netscape Version 2 for OS/2 - 'Mozilla/4.04 [en] (X11; U; AIX 4.2; Nav)' NS for AIX - 'Mozilla/4.05 [en] (X11; U; Linux 2.0.32 i586)' NS for Linux - - Note that Internet Explorer tries hard to be compatible in every way: - 'Mozilla/4.0 (compatible; MSIE 4.01; Windows 95)' MSIE for W95 - - Mozilla is not the only possible User-Agent name: - 'Konqueror/1.0' KDE File Manager desktop client - 'Lynx/2.7.1 libwww-FM/2.14' Lynx command line browser - -COOKIES - - Cookies are generally used by web servers to keep state information at the - client's side. The server sets cookies by sending a response line in the - headers that looks like 'Set-Cookie: <data>' where the data part then - typically contains a set of NAME=VALUE pairs (separated by semicolons ';' - like "NAME1=VALUE1; NAME2=VALUE2;"). The server can also specify for what - path the "cookie" should be used for (by specifying "path=value"), when the - cookie should expire ("expire=DATE"), for what domain to use it - ("domain=NAME") and if it should be used on secure connections only - ("secure"). - - If you've received a page from a server that contains a header like: - Set-Cookie: sessionid=boo123; path="/foo"; - - it means the server wants that first pair passed on when we get anything in - a path beginning with "/foo". - - Example, get a page that wants my name passed in a cookie: - - curl -b "name=Daniel" www.sillypage.com - - Curl also has the ability to use previously received cookies in following - sessions. If you get cookies from a server and store them in a file in a - manner similar to: - - curl --dump-header headers www.example.com - - ... you can then in a second connect to that (or another) site, use the - cookies from the 'headers' file like: - - curl -b headers www.example.com - - Note that by specifying -b you enable the "cookie awareness" and with -L - you can make curl follow a location: (which often is used in combination - with cookies). So that if a site sends cookies and a location, you can - use a non-existing file to trig the cookie awareness like: - - curl -L -b empty-file www.example.com - - The file to read cookies from must be formatted using plain HTTP headers OR - as netscape's cookie file. Curl will determine what kind it is based on the - file contents. - -PROGRESS METER - - The progress meter exists to show a user that something actually is - happening. The different fields in the output have the following meaning: - - % Total % Received % Xferd Average Speed Time Curr. - Dload Upload Total Current Left Speed - 0 151M 0 38608 0 0 9406 0 4:41:43 0:00:04 4:41:39 9287 - - From left-to-right: - % - percentage completed of the whole transfer - Total - total size of the whole expected transfer - % - percentage completed of the download - Received - currently downloaded amount of bytes - % - percentage completed of the upload - Xferd - currently uploaded amount of bytes - Average Speed - Dload - the average transfer speed of the download - Average Speed - Upload - the average transfer speed of the upload - Time Total - expected time to complete the operation - Time Current - time passed since the invoke - Time Left - expected time left to completetion - Curr.Speed - the average transfer speed the last 5 seconds (the first - 5 seconds of a transfer is based on less time of course.) - - The -# option will display a totally different progress bar that doesn't - need much explanation! - -SPEED LIMIT - - Curl offers the user to set conditions regarding transfer speed that must - be met to let the transfer keep going. By using the switch -y and -Y you - can make curl abort transfers if the transfer speed doesn't exceed your - given lowest limit for a specified time. - - To let curl abandon downloading this page if its slower than 3000 bytes per - second for 1 minute, run: - - curl -y 3000 -Y 60 www.far-away-site.com - - This can very well be used in combination with the overall time limit, so - that the above operatioin must be completed in whole within 30 minutes: - - curl -m 1800 -y 3000 -Y 60 www.far-away-site.com - -CONFIG FILE - - Curl automatically tries to read the .curlrc file (or _curlrc file on win32 - systems) from the user's home dir on startup. The config file should be - made up with normal command line switches. Comments can be used within the - file. If the first letter on a line is a '#'-letter the rest of the line - is treated as a comment. - - Example, set default time out and proxy in a config file: - - # We want a 30 minute timeout: - -m 1800 - # ... and we use a proxy for all accesses: - -x proxy.our.domain.com:8080 - - White spaces ARE significant at the end of lines, but all white spaces - leading up to the first characters of each line are ignored. - - Prevent curl from reading the default file by using -q as the first command - line parameter, like: - - curl -q www.thatsite.com - - Force curl to get and display a local help page in case it is invoked - without URL by making a config file similar to: - - # default url to get - http://help.with.curl.com/curlhelp.html - - You can specify another config file to be read by using the -K/--config - flag. If you set config file name to "-" it'll read the config from stdin, - which can be handy if you want to hide options from being visible in process - tables etc: - - echo "-u user:passwd" | curl -K - http://that.secret.site.com - -EXTRA HEADERS - - When using curl in your own very special programs, you may end up needing - to pass on your own custom headers when getting a web page. You can do - this by using the -H flag. - - Example, send the header "X-you-and-me: yes" to the server when getting a - page: - - curl -H "X-you-and-me: yes" www.love.com - - This can also be useful in case you want curl to send a different text in - a header than it normally does. The -H header you specify then replaces the - header curl would normally send. - -FTP and PATH NAMES - - Do note that when getting files with the ftp:// URL, the given path is - relative the directory you enter. To get the file 'README' from your home - directory at your ftp site, do: - - curl ftp://user:passwd@my.site.com/README - - But if you want the README file from the root directory of that very same - site, you need to specify the absolute file name: - - curl ftp://user:passwd@my.site.com//README - - (I.e with an extra slash in front of the file name.) - -FTP and firewalls - - The FTP protocol requires one of the involved parties to open a second - connction as soon as data is about to get transfered. There are two ways to - do this. - - The default way for curl is to issue the PASV command which causes the - server to open another port and await another connection performed by the - client. This is good if the client is behind a firewall that don't allow - incoming connections. - - curl ftp.download.com - - If the server for example, is behind a firewall that don't allow connections - on other ports than 21 (or if it just doesn't support the PASV command), the - other way to do it is to use the PORT command and instruct the server to - connect to the client on the given (as parameters to the PORT command) IP - number and port. - - The -P flag to curl allows for different options. Your machine may have - several IP-addresses and/or network interfaces and curl allows you to select - which of them to use. Default address can also be used: - - curl -P - ftp.download.com - - Download with PORT but use the IP address of our 'le0' interface: - - curl -P le0 ftp.download.com - - Download with PORT but use 192.168.0.10 as our IP address to use: - - curl -P 192.168.0.10 ftp.download.com - -HTTPS - - Secure HTTP requires SSL libraries to be installed and used when curl is - built. If that is done, curl is capable of retrieving and posting documents - using the HTTPS procotol. - - Example: - - curl https://www.secure-site.com - - Curl is also capable of using your personal certificates to get/post files - from sites that require valid certificates. The only drawback is that the - certificate needs to be in PEM-format. PEM is a standard and open format to - store certificates with, but it is not used by the most commonly used - browsers (Netscape and MSEI both use the so called PKCS#12 format). If you - want curl to use the certificates you use with your (favourite) browser, you - may need to download/compile a converter that can convert your browser's - formatted certificates to PEM formatted ones. This kind of converter is - included in recent versions of OpenSSL, and for older versions Dr Stephen - N. Henson has written a patch for SSLeay that adds this functionality. You - can get his patch (that requires an SSLeay installation) from his site at: - http://www.drh-consultancy.demon.co.uk/ - - Example on how to automatically retrieve a document using a certificate with - a personal password: - - curl -E /path/to/cert.pem:password https://secure.site.com/ - - If you neglect to specify the password on the command line, you will be - prompted for the correct password before any data can be received. - - Many older SSL-servers have problems with SSLv3 or TLS, that newer versions - of OpenSSL etc is using, therefore it is sometimes useful to specify what - SSL-version curl should use. Use -3 or -2 to specify that exact SSL version - to use: - - curl -2 https://secure.site.com/ - - Otherwise, curl will first attempt to use v3 and then v2. - -RESUMING FILE TRANSFERS - - To continue a file transfer where it was previously aborted, curl supports - resume on http(s) downloads as well as ftp uploads and downloads. - - Continue downloading a document: - - curl -c -o file ftp://ftp.server.com/path/file - - Continue uploading a document(*1): - - curl -c -T file ftp://ftp.server.com/path/file - - Continue downloading a document from a web server(*2): - - curl -c -o file http://www.server.com/ - - (*1) = This requires that the ftp server supports the non-standard command - SIZE. If it doesn't, curl will say so. - - (*2) = This requires that the wb server supports at least HTTP/1.1. If it - doesn't, curl will say so. - -TIME CONDITIONS - - HTTP allows a client to specify a time condition for the document it - requests. It is If-Modified-Since or If-Unmodified-Since. Curl allow you to - specify them with the -z/--time-cond flag. - - For example, you can easily make a download that only gets performed if the - remote file is newer than a local copy. It would be made like: - - curl -z local.html http://remote.server.com/remote.html - - Or you can download a file only if the local file is newer than the remote - one. Do this by prepending the date string with a '-', as in: - - curl -z -local.html http://remote.server.com/remote.html - - You can specify a "free text" date as condition. Tell curl to only download - the file if it was updated since yesterday: - - curl -z yesterday http://remote.server.com/remote.html - - Curl will then accept a wide range of date formats. You always make the date - check the other way around by prepending it with a dash '-'. - -DICT - - For fun try - - curl dict://dict.org/m:curl - curl dict://dict.org/d:heisenbug:jargon - curl dict://dict.org/d:daniel:web1913 - - Aliases for 'm' are 'match' and 'find', and aliases for 'd' are 'define' - and 'lookup'. For example, - - curl dict://dict.org/find:curl - - Commands that break the URL description of the RFC (but not the DICT - protocol) are - - curl dict://dict.org/show:db - curl dict://dict.org/show:strat - - Authentication is still missing (but this is not required by the RFC) - -LDAP - - If you have installed the OpenLDAP library, curl can take advantage of it - and offer ldap:// support. - - LDAP is a complex thing and writing an LDAP query is not an easy task. I do - advice you to dig up the syntax description for that elsewhere, RFC 1959 if - no other place is better. - - To show you an example, this is now I can get all people from my local LDAP - server that has a certain sub-domain in their email address: - - curl -B "ldap://ldap.frontec.se/o=frontec??sub?mail=*sth.frontec.se" - - If I want the same info in HTML format, I can get it by not using the -B - (enforce ASCII) flag. - -ENVIRONMENT VARIABLES - - Curl reads and understands the following environment variables: - - HTTP_PROXY, HTTPS_PROXY, FTP_PROXY, GOPHER_PROXY - - They should be set for protocol-specific proxies. General proxy should be - set with - - ALL_PROXY - - A comma-separated list of host names that shouldn't go through any proxy is - set in (only an asterisk, '*' matches all hosts) - - NO_PROXY - - If a tail substring of the domain-path for a host matches one of these - strings, transactions with that node will not be proxied. - - - The usage of the -x/--proxy flag overrides the environment variables. - -NETRC - - Unix introduced the .netrc concept a long time ago. It is a way for a user - to specify name and password for commonly visited ftp sites in a file so - that you don't have to type them in each time you visit those sites. You - realize this is a big security risk if someone else gets hold of your - passwords, so therefor most unix programs won't read this file unless it is - only readable by yourself (curl doesn't care though). - - Curl supports .netrc files if told so (using the -n/--netrc option). This is - not restricted to only ftp, but curl can use it for all protocols where - authentication is used. - - A very simple .netrc file could look something like: - - machine curl.haxx.nu login iamdaniel password mysecret - -CUSTOM OUTPUT - - To better allow script programmers to get to know about the progress of - curl, the -w/--write-out option was introduced. Using this, you can specify - what information from the previous transfer you want to extract. - - To display the amount of bytes downloaded together with some text and an - ending newline: - - curl -w 'We downloaded %{size_download} bytes\n' www.download.com - -MAILING LIST - - We have an open mailing list to discuss curl, its development and things - relevant to this. - - To subscribe, mail curl-request@contactor.se with "subscribe <your email - address>" in the body. - - To post to the list, mail curl@contactor.se. - - To unsubcribe, mail curl-request@contactor.se with "unsubscribe <your - subscribed email address>" in the body. - diff --git a/README.libcurl b/README.libcurl deleted file mode 100644 index ccec76150..000000000 --- a/README.libcurl +++ /dev/null @@ -1,108 +0,0 @@ - _ _ _ _ - | (_) |__ ___ _ _ _ __| | - | | | '_ \ / __| | | | '__| | - | | | |_) | (__| |_| | | | | - |_|_|_.__/ \___|\__,_|_| |_| - - - How To Use Libcurl In Your Program: - (by Ralph Beckmann <rabe@uni-paderborn.de>) - -NOTE: If you plan to use libcurl.a in Threads under Linux, do not use the old -gcc-2.7.x because the function 'gethostbyname' seems not to be thread-safe, -that is to say an unavoidable SEGMENTATION FAULT might occur. - - -1. a) In a C-Program: - #include "curl.h" - - b) In a C++-Program: - extern "C" { - #include "curl.h" - } - -2. char *url="http://www.domain.com"; - curl_urlget (URGTAG_URL, url, - URGTAG_FLAGS, CONF_NOPROGRESS, - URGTAG_ERRORBUFFER, errorBuffer, - URGTAG_WRITEFUNCTION, (size_t (*)(void *, int, int, FILE -*))handle_data, - URGTAG_TIMEOUT, 30, /* or anything You want */ - ... - URGTAG_DONE); - -3. size_t handle_data (const void *ptr, size_t size, size_t nitems, - FILE *stream) - { - (void)stream; /* stop complaining using g++ -Wall */ - if ((int)nitems <= 0) { - return (size_t)0; - } - fprintf(stdout, (char *)ptr); /* or do anything else with it */ - return nitems; - } - -4.

It seems as - if Netscape doesn't support this, and not many servers do. Although this is - a lot better authentication method than the more common "Basic". Basic - sends the password in cleartext over the network, this "Digest" method uses - a challange-response protocol which increases security quite a lot. - - * Different FTP Upload Through Web Proxy - I don't know any web proxies that allow CONNECT through on port 21, but - that would be the best way to do ftp upload. All we would need to do would - be to 'CONNECT <host>:<port> HTTP/1.0\r\n\r\n' and then do business as - usual. I least I think so. It would be fun if someone tried this... - - * Multiple Proxies? - Is there anyone that actually uses serial-proxies? I mean, send CONNECT to - the first proxy to connect to the second proxy to which you send CONNECT to - connect to the remote host (or even more iterations). Is there anyone - wanting curl to support it? (Not that it would be hard, just confusing...) - - * Other proxies - Ftp-kind proxy, Socks5, whatever kind of proxies are there? - - * IPv6 Awareness - Where ever it would fit. I am not that into v6 yet to fully grasp what we - would need to do, but letting the autoconf search for v6-versions of a few - functions and then use them instead is of course the first thing to do... - RFC 2428 "FTP Extensions for IPv6 and NATs" will be interesting. PORT - should be replaced with EPRT for IPv6, and EPSV instead of PASV. - - * An automatic RPM package maker - Please, write me a script that makes it. It'd make my day. - - * SSL for more protocols, like SSL-FTP... - (http://search.ietf.org/internet-drafts/draft-murray-auth-ftp-ssl-05.txt) - - * HTTP POST resume using Range: - - * Make curl capable of verifying the server's certificate when connecting - with HTTPS://. - - * Make the timeout work as expected! diff --git a/curl.1 b/curl.1 deleted file mode 100644 index 7683a117d..000000000 --- a/curl.1 +++ /dev/null @@ -1,598 +0,0 @@ -.\" You can view this file with: -.\" nroff -man curl.1 -.\" Written by Daniel Stenberg -.\" -.TH curl 1 "13 March 2000" "Curl 6.5" "Curl Manual" -.SH NAME -curl \- get a URL with FTP, TELNET, LDAP, GOPHER, DICT, FILE, HTTP or -HTTPS syntax. -.SH SYNOPSIS -.B curl [options] -.I url -.SH DESCRIPTION -.B curl -is a client to get documents/files from servers, using any of the -supported protocols. The command is designed to work without user -interaction or any kind of interactivity. - -curl offers a busload of useful tricks like proxy support, user -authentication, ftp upload, HTTP post, SSL (https:) connections, cookies, file -transfer resume and more. -.SH URL -The URL syntax is protocol dependent. You'll find a detailed description in -RFC 2396. - -You can specify multiple URLs or parts of URLs by writing part sets within -braces as in: - - http://site.{one,two,three}.com - -or you can get sequences of alphanumeric series by using [] as in: - - ftp://ftp.numericals.com/file[1-100].txt - ftp://ftp.numericals.com/file[001-100].txt (with leading zeros) - ftp://ftp.letters.com/file[a-z].txt - -It is possible to specify up to 9 sets or series for a URL, but no nesting is -supported at the moment: - - http://www.any.org/archive[1996-1999]/volume[1-4]part{a,b,c,index}.html -.SH OPTIONS -.IP "-a/--append" -(FTP) -When used in a ftp upload, this will tell curl to append to the target -file instead of overwriting it. If the file doesn't exist, it will -be created. -.IP "-A/--user-agent <agent string>" -(HTTP) -Specify the User-Agent string to send to the HTTP server. Some badly done CGIs -fail if its not set to "Mozilla/4.0". To encode blanks in the string, -surround the string with single quote marks. This can also be set with the --H/--header flag of course. -.IP "-b/--cookie <name=data>" -(HTTP) -Pass the data to the HTTP server as a cookie. It is supposedly the -data previously received from the server in a "Set-Cookie:" line. -The data should be in the format "NAME1=VALUE1; NAME2=VALUE2". - -If no '=' letter is used in the line, it is treated as a filename to use to -read previously stored cookie lines from, which should be used in this session -if they match. Using this method also activates the "cookie parser" which -will make curl record incoming cookies too, which may be handy if you're using -this in combination with the -L/--location option. The file format of the file -to read cookies from should be plain HTTP headers or the netscape cookie file -format. - -.B NOTE -that the file specified with -b/--cookie is only used as input. No cookies -will be stored in the file. To store cookies, save the HTTP headers to a file -using -D/--dump-header! -.IP "-B/--ftp-ascii" -(FTP/LDAP) -Use ASCII transfer when getting an FTP file or LDAP info. For FTP, this can -also be enforced by using an URL that ends with ";type=A". -.IP "-c/--continue" -Continue/Resume a previous file transfer. This instructs curl to -continue appending data on the file where it was previously left, -possibly because of a broken connection to the server. There must be -a named physical file to append to for this to work. -Note: Upload resume is depening on a command named SIZE not always -present in all ftp servers! Upload resume is for FTP only. -HTTP resume is only possible with HTTP/1.1 or later servers. -.IP "-C/--continue-at <offset>" -Continue/Resume a previous file transfer at the given offset. The -given offset is the exact number of bytes that will be skipped -counted from the beginning of the source file before it is transfered -to the destination. -If used with uploads, the ftp server command SIZE will not be used by -curl. Upload resume is for FTP only. -HTTP resume is only possible with HTTP/1.1 or later servers. -.IP "-d/--data <data>" -(HTTP) -Sends the specified data in a POST request to the HTTP server. Note -that the data is sent exactly as specified with no extra processing. -The data is expected to be "url-encoded". This will cause curl to -pass the data to the server using the content-type -application/x-www-form-urlencoded. Compare to -F. - -If you start the data with the letter @, the rest should be a file name to -read the data from, or - if you want curl to read the data from stdin. -The contents of the file must already be url-encoded. -.IP "-D/--dump-header <file>" -(HTTP/FTP) -Write the HTTP headers to this file. Write the FTP file info to this -file if -I/--head is used. - -This option is handy to use when you want to store the cookies that a HTTP -site sends to you. The cookies could then be read in a second curl invoke by -using the -b/--cookie option! -.IP "-e/--referer <URL>" -(HTTP) -Sends the "Referer Page" information to the HTTP server. Some badly -done CGIs fail if it's not set. This can also be set with the -H/--header -flag of course. -.IP "-E/--cert <certificate[:password]>" -(HTTPS) -Tells curl to use the specified certificate file when getting a file -with HTTPS. The certificate must be in PEM format. -If the optional password isn't specified, it will be queried for on -the terminal. Note that this certificate is the private key and the private -certificate concatenated! -.IP "-f/--fail" -(HTTP) -Fail silently (no output at all) on server errors. This is mostly done -like this to better enable scripts etc to better deal with failed -attempts. In normal cases when a HTTP server fails to deliver a -document, it returns a HTML document stating so (which often also -describes why and more). This flag will prevent curl from -outputting that and fail silently instead. -.IP "-F/--form <name=content>" -(HTTP) -This lets curl emulate a filled in form in which a user has pressed -the submit button. This causes curl to POST data using the -content-type multipart/form-data according to RFC1867. This enables -uploading of binary files etc. To force the 'content' part to be -read from a file, prefix the file name with an @ sign. Example, to -send your password file to the server, where 'password' is the -name of the form-field to which /etc/passwd will be the input: - -.B curl --F password=@/etc/passwd www.mypasswords.com - -To read the file's content from stdin insted of a file, use - where the file -name should've been. -.IP "-h/--help" -Usage help. -.IP "-H/--header <header>" -(HTTP) -Extra header to use when getting a web page. You may specify any number of -extra headers. Note that if you should add a custom header that has the same -name as one of the internal ones curl would use, your externally set header -will be used instead of the internal one. This allows you to make even -trickier stuff than curl would normally do. You should not replace internally -set headers without knowing perfectly well what you're doing. -.IP "-i/--include" -(HTTP) -Include the HTTP-header in the output. The HTTP-header includes things -like server-name, date of the document, HTTP-version and more... -.IP "-I/--head" -(HTTP/FTP) -Fetch the HTTP-header only! HTTP-servers feature the command HEAD -which this uses to get nothing but the header of a document. When used -on a FTP file, curl displays the file size only. -.IP "-K/--config <config file>" -Specify which config file to read curl arguments from. The config -file is a text file in which command line arguments can be written -which then will be used as if they were written on the actual command -line. If the first column of a config line is a '#' character, the -rest of the line will be treated as a comment. - -Specify the filename as '-' to make curl read the file from stdin. -.IP "-l/--list-only" -(FTP) -When listing an FTP directory, this switch forces a name-only view. -Especially useful if you want to machine-parse the contents of an FTP -directory since the normal directory view doesn't use a standard look -or format. -.IP "-L/--location" -(HTTP/HTTPS) -If the server reports that the requested page has a different location -(indicated with the header line Location:) this flag will let curl -attempt to reattempt the get on the new place. If used together with --i or -I, headers from all requested pages will be shown. -.IP "-m/--max-time <seconds>" -Maximum time in seconds that you allow the whole operation to take. -This is useful for preventing your batch jobs from hanging for hours -due to slow networks or links going down. -This doesn't work properly in win32 systems. -.IP "-M/--manual" -Manual. Display the huge help text. -.IP "-n/--netrc" -Makes curl scan the -.I .netrc -file in the user's home directory for login name and password. This is -typically used for ftp on unix. If used with http, curl will enable user -authentication. See -.BR netrc(5) -for details on the file format. Curl will not complain if that file -hasn't the right permissions (it should not be world nor group -readable). The environment variable "HOME" is used to find the home -directory. - -A quick and very simple example of how to setup a -.I .netrc -to allow curl to ftp to the machine host.domain.com with user name -'myself' and password 'secret' should look similar to: - -.B "machine host.domain.com login myself password secret" -.IP "-N/--no-buffer" -Disables the buffering of the output stream. In normal work situations, curl -will use a standard buffered output stream that will have the effect that it -will output the data in chunks, not necessarily exactly when the data arrives. -Using this option will disable that buffering. -.IP "-o/--output <file>" -Write output to <file> instead of stdout. If you are using {} or [] to fetch -multiple documents, you can use '#' followed by a number in the <file> -specifier. That variable will be replaced with the current string for the URL -being fetched. Like in: - - curl http://{one,two}.site.com -o "file_#1.txt" - -or use several variables like: - - curl http://{site,host}.host[1-5].com -o "#1_#2" -.IP "-O/--remote-name" -Write output to a local file named like the remote file we get. (Only -the file part of the remote file is used, the path is cut off.) -.IP "-P/--ftpport <address>" -(FTP) -Reverses the initiator/listener roles when connecting with ftp. This -switch makes Curl use the PORT command instead of PASV. In -practice, PORT tells the server to connect to the client's specified -address and port, while PASV asks the server for an ip address and -port to connect to. <address> should be one of: -.RS -.TP 12 -.B interface -i.e "eth0" to specify which interface's IP address you want to use (Unix only) -.TP -.B "IP address" -i.e "192.168.10.1" to specify exact IP number -.TP -.B "host name" -i.e "my.host.domain" to specify machine -.TP -.B "-" -(any single-letter string) to make it pick the machine's default -.RE -.IP "-q" -If used as the first parameter on the command line, the -.I $HOME/.curlrc -file will not be read and used as a config file. -.IP "-Q/--quote <comand>" -(FTP) Send an arbitrary command to the remote FTP server, by using the QUOTE -command of the server. Not all servers support this command, and the set of -QUOTE commands are server specific! Quote commands are sent BEFORE the -transfer is taking place. To make commands take place after a successful -transfer, prefix them with a dash '-'. You may specify any amount of commands -to be run before and after the transfer. If the server returns failure for one -of the commands, the entire operation will be aborted. -.IP "-r/--range <range>" -(HTTP/FTP) -Retrieve a byte range (i.e a partial document) from a HTTP/1.1 or FTP -server. Ranges can be specified in a number of ways. -.RS -.TP 10 -.B 0-499 -specifies the first 500 bytes -.TP -.B 500-999 -specifies the second 500 bytes -.TP -.B -500 -specifies the last 500 bytes -.TP -.B 9500 -specifies the bytes from offset 9500 and forward -.TP -.B 0-0,-1 -specifies the first and last byte only(*)(H) -.TP -.B 500-700,600-799 -specifies 300 bytes from offset 500(H) -.TP -.B 100-199,500-599 -specifies two separate 100 bytes ranges(*)(H) -.RE - -(*) = NOTE that this will cause the server to reply with a multipart -response! - -You should also be aware that many HTTP/1.1 servers do not have this feature -enabled, so that when you attempt to get a range, you'll instead get the whole -document. - -FTP range downloads only support the simple syntax 'start-stop' (optionally -with one of the numbers omitted). It depends on the non-RFC command SIZE. -.IP "-s/--silent" -Silent mode. Don't show progress meter or error messages. Makes -Curl mute. -.IP "-S/--show-error" -When used with -s it makes curl show error message if it fails. -.IP "-t/--upload" -Transfer the stdin data to the specified file. Curl will read -everything from stdin until EOF and store with the supplied name. If -this is used on a http(s) server, the PUT command will be used. -.IP "-T/--upload-file <file>" -Like -t, but this transfers the specified local file. If there is no -file part in the specified URL, Curl will append the local file -name. NOTE that you must use a trailing / on the last directory to -really prove to Curl that there is no file name or curl will -think that your last directory name is the remote file name to -use. That will most likely cause the upload operation to fail. If -this is used on a http(s) server, the PUT command will be used. -.IP "-u/--user <user:password>" -Specify user and password to use when fetching. See README.curl for detailed -examples of how to use this. If no password is specified, curl will -ask for it interactively. -.IP "-U/--proxy-user <user:password>" -Specify user and password to use for Proxy authentication. If no -password is specified, curl will ask for it interactively. -.IP "-v/--verbose" -Makes the fetching more verbose/talkative. Mostly usable for -debugging. Lines starting with '>' means data sent by curl, '<' -means data received by curl that is hidden in normal cases and lines -starting with '*' means additional info provided by curl. -.IP "-V/--version" -Displays the full version of curl, libcurl and other 3rd party libraries -linked with the executable. -.IP "-w/--write-out <format>" -Defines what to display after a completed and successful operation. The format -is a string that may contain plain text mixed with any number of variables. The -string can be specified as "string", to get read from a particular file you -specify it "@filename" and to tell curl to read the format from stdin you -write "@-". - -The variables present in the output format will be substituted by the value or -text that curl thinks fit, as described below. All variables are specified -like %{variable_name} and to output a normal % you just write them like -%%. You can output a newline by using \\n, a carrige return with \\r and a tab -space with \\t. - -.B NOTE: -The %-letter is a special letter in the win32-environment, where all -occurrences of % must be doubled when using this option. - -Available variables are at this point: -.RS -.TP 15 -.B url_effective -The URL that was fetched last. This is mostly meaningful if you've told curl -to follow location: headers. -.TP -.B http_code -The numerical code that was found in the last retrieved HTTP(S) page. -.TP -.B time_total -The total time, in seconds, that the full operation lasted. The time will be -displayed with millisecond resolution. -.TP -.B time_namelookup -The time, in seconds, it took from the start until the name resolving was -completed. -.TP -.B time_connect -The time, in seconds, it took from the start until the connect to the remote -host (or proxy) was completed. -.TP -.B time_pretransfer -The time, in seconds, it took from the start until the file transfer is just -about to begin. This includes all pre-transfer commands and negotiations that -are specific to the particular protocol(s) involved. -.TP -.B size_download -The total amount of bytes that were downloaded. -.TP -.B size_upload -The total amount of bytes that were uploaded. -.TP -.B speed_download -The average download speed that curl measured for the complete download. -.TP -.B speed_upload -The average upload speed that curl measured for the complete download. -.RE -.IP "-x/--proxy <proxyhost[:port]>" -Use specified proxy. If the port number is not specified, it is assumed at -port 1080. -.IP "-X/--request <command>" -(HTTP) -Specifies a custom request to use when communicating with the HTTP server. -The specified request will be used instead of the standard GET. Read the -HTTP 1.1 specification for details and explanations. - -(FTP) -Specifies a custom FTP command to use instead of LIST when doing file lists -with ftp. -.IP "-y/--speed-time <time>" -If a download is slower than speed-limit bytes per second during a speed-time -period, the download gets aborted. If speed-time is used, the default -speed-limit will be 1 unless set with -y. -.IP "-Y/--speed-limit <speed>" -If a download is slower than this given speed, in bytes per second, for -speed-time seconds it gets aborted. speed-time is set with -Y and is 30 if -not set. -.IP "-z/--time-cond <date expression>" -(HTTP) -Request to get a file that has been modified later than the given time and -date, or one that has been modified before that time. The date expression can -be all sorts of date strings or if it doesn't match any internal ones, it -tries to get the time from a given file name instead! See the -.BR "GNU date(1)" -man page for date expression details. - -Start the date expression with a dash (-) to make it request for a document -that is older than the given date/time, default is a document that is newer -than the specified date/time. -.IP "-3/--sslv3" -(HTTPS) -Forces curl to use SSL version 3 when negotiating with a remote SSL server. -.IP "-2/--sslv2" -(HTTPS) -Forces curl to use SSL version 2 when negotiating with a remote SSL server. -.IP "-#/--progress-bar" -Make curl display progress information as a progress bar instead of the -default statistics. -.IP "--crlf" -(FTP) Convert LF to CRLF in upload. Useful for MVS (OS/390). -.IP "--stderr <file>" -Redirect all writes to stderr to the specified file instead. If the file name -is a plain '-', it is instead written to stdout. This option has no point when -you're using a shell with decent redirecting capabilities. -.SH FILES -.I ~/.curlrc -.RS -Default config file. - -.SH ENVIRONMENT -.IP "HTTP_PROXY [protocol://]<host>[:port]" -Sets proxy server to use for HTTP. -.IP "HTTPS_PROXY [protocol://]<host>[:port]" -Sets proxy server to use for HTTPS. -.IP "FTP_PROXY [protocol://]<host>[:port]" -Sets proxy server to use for FTP. -.IP "GOPHER_PROXY [protocol://]<host>[:port]" -Sets proxy server to use for GOPHER. -.IP "ALL_PROXY [protocol://]<host>[:port]" -Sets proxy server to use if no protocol-specific proxy is set. -.IP "NO_PROXY <comma-separated list of hosts>" -list of host names that shouldn't go through any proxy. If set to a -asterisk '*' only, it matches all hosts. -.IP "COLUMNS <integer>" -The width of the terminal.
