* avio: Copy URLContext generic options into child URLContextsMartin Storsjö2016-03-24
| | | | | | | | | | | | | | | Since all URLContexts have the same AVOptions, such AVOptions will be applied on the outermost context only and removed from the dict, while they probably make sense on all contexts. This makes sure that rw_timeout gets propagated to the innermost URLContext (to make sure it gets passed to the tcp protocol, when opening a http connection for instance). Alternatively, such matching options would be kept in the dict and only removed after the ffurl_connect call. Signed-off-by: Martin Storsjö <martin@martin.st>
* urlprotocol: receive a list of protocols from the callerAnton Khirnov2016-02-22
| | | | | This way, the decisions about which protocols are available for use in any given situations can be delegated to the caller.
* lavf: reorganize URLProtocolsAnton Khirnov2016-02-22
| | | | | | | | | | Instead of a linked list constructed at av_register_all(), store them in a constant array of pointers. Since no registration is necessary now, this removes some global state from lavf. This will also allow the urlprotocol layer caller to limit the available protocols in a simple and flexible way in the following commits.

* http: Fix authentication, broken since 6a463e7fbMartin Storsjö2014-08-13
| | | | | | | | | | The cur_*auth_type variables were set before the http_connect call prior to 6a463e7fb - their sole purpose is to record the authentication type used to do the latest request, since parsing the http response sets the new type in the auth state.

* http: Stop reading after receiving the whole file for non-chunked transfersMartin Storsjö2014-08-13
| | | | | | | | | | | | | | | | | | | | | | | | Previously this logic was only used if the server didn't respond with Connection: close, but use it even for that case, if the server response is non-chunked. Originally the http code has relied on Connection: close to close the socket when the file/stream is received - the http protocol code just kept reading from the socket until the socket was closed. In f240ed18 we added a check for the file size, because some http servers didn't respond with Connection: close (and wouldn't close the socket) even though we requested it, which meant that the http protocol blocked for a long time at the end of files, waiting for a socket level timeout. When reading over tls, trying to read at the end of the connection, when the peer has closed the connection, can produce spurious (but harmless) warnings. Therefore always voluntarily stop reading when the specified file size has been received, if not using a chunked transfer encoding. (For chunked transfers, we already return 0 as soon as we get the chunk header indicating end of stream.) Signed-off-by: Martin Storsjö <martin@martin.st>

* http: Properly initialize icy headers stringAlessandro Ghedini2014-03-12
| | | | | | | | | | | | | | The icy_metadata_headers string never gets initialized, so, during the first call to av_strlcatf() in parse_icy(), strlen() will be called on a pointer to uninitialized memory. At best this causes some garbage data to be left at the start of the string. By initializing icy_metadata_headers to the empty string, the first call to strlen() will always return 0, so that data is appended from the start of the string.

* http: Check the auth string contents and not only the pointerMichael Niedermayer2013-10-14

* http: Support auth method detection for POSTMartin Storsjö2013-10-13
| | | | | | | | | | | | | | | | | | | | | | | | Inspired by a patch by Jakob van Bethlehem. But instead of doing an empty POST first to trigger the WWW-Authenticate header (which would succeed if no auth actually was required), add an Expect: 100-continue header, which is meant to be used exactly for cases like this. The header is added if doing a post, and the user has specified authentication but we don't know the auth method yet. Not all common HTTP servers support the Expect: 100-continue header, though, so we only try to use it when it really is needed. The user can request it to be added for other POST requests as well via an option - which would allow the caller to know immediately that the POST has failed (e.g. if no auth was provided but the server required it, or if the target URL simply doesn't exist). This is only done for write mode posts (e.g. posts without pre-set post_data) - for posts with pre-set data, we can just redo the post if it failed due to 401.

* http: Add an option for forcing basic authenticationMartin Storsjö2013-10-13
| | | | | | | | | | | | | The default is to autodetect the auth method. This does require one extra request (and also closing and reopening the http connection). For some cases such as HTTP POST, the autodetection is not handled properly (yet). No option is added for digest, since this method requires getting nonce parameters from the server first and can't be used straight away like Basic. Signed-off-by: Martin Storsjö <martin@martin.st>
* http: Pass options through to the nested protocolMartin Storsjö2013-09-26
| | | | | | | | When passing a dict to the nested protocol, it will consume the used options from it, so a separate copy needs to be used when reopening the connection multiple times. Signed-off-by: Martin Storsjö <martin@martin.st>

* lavf: Handle the environment variable no_proxy more properlyMartin Storsjö2013-02-27
| | | | | | | | | | | | | | | | | | | | The handling of the environment variable no_proxy, present since one of the initial commits (de6d9b6404), is inconsistent with how many other applications and libraries interpret this variable. Its bare presence does not indicate that the use of proxies should be skipped, but it is some sort of pattern for hosts that does not need using a proxy (e.g. for a local network). As investigated by Rudolf Polzer, different libraries handle this in different ways, some supporting IP address masks, some supporting arbitrary globbing using *, some just checking that the pattern matches the end of the hostname without regard for whether it actually is the right domain or a domain that ends in the same string. This simple logic should be pretty similar to the logic used by lynx and curl. Signed-off-by: Martin Storsjö <martin@martin.st>

* http: Increase buffer sizes to cope with longer URIsDuncan Salerno2012-09-28
| | | | | | | | | | | | | Use the MAX_URL_SIZE define where applicable. Increase buffer sizes for all buffers that need to fit a long pathname - buffers that need to fit only the hostname (and other short strings, but not the pathname - such as "headers" in http_connect) are kept at 1024 bytes for now. Also increase the max line length in http_read_header, since it might need to contain a full url for Location: redirects. Signed-off-by: Martin Storsjö <martin@martin.st>
