Definition at line 45 of file TWebFile.h.

◆ TWebFile() [2/3]

TWebFile::TWebFile	(	const char *	url,
		Option_t *	opt = `""`
	)

Create a Web file object.

A web file is the same as a read-only TFile except that it is being read via a HTTP server. The url argument must be of the form: http://host.dom.ain/file.root. The opt can be "NOPROXY", to bypass any set "http_proxy" shell variable. The proxy can be specified as (in sh, or equivalent csh): export http_proxy=http://pcsalo.cern.ch:3128 The proxy can also be specified via the static method TWebFile::SetProxy(). Basic authentication (AuthType Basic) is supported. The user name and passwd can be specified in the url like this: http://username:mypasswd@pcsalo.cern.ch/files/aap.root If the file specified in the URL does not exist or is not accessible the kZombie bit will be set in the TWebFile object. Use IsZombie() to see if the file is accessible. The preferred interface to this constructor is via TFile::Open().

A web file is the same as a read-only TFile except that it is being read via a HTTP server. Make sure url is a valid TUrl object. The opt can be "NOPROXY", to bypass any set "http_proxy" shell variable. The proxy can be specified as (in sh, or equivalent csh): export http_proxy=http://pcsalo.cern.ch:3128 The proxy can also be specified via the static method TWebFile::SetProxy(). Basic authentication (AuthType Basic) is supported. The user name and passwd can be specified in the url like this: http://username:mypasswd@pcsalo.cern.ch/files/aap.root If the file specified in the URL does not exist or is not accessible the kZombie bit will be set in the TWebFile object.

Definition at line 1028 of file TWebFile.cxx.

◆ GetHunk()

Int_t TWebFile::GetHunk	(	TSocket *	s,
		char *	hunk,
		Int_t	maxsize
	)

protectedvirtual

Read a hunk of data from the socket, up until a terminator.

The hunk is limited by whatever the TERMINATOR callback chooses as its terminator. For example, if terminator stops at newline, the hunk will consist of a line of data; if terminator stops at two newlines, it can be used to read the head of an HTTP response. Upon determining the boundary, the function returns the data (up to the terminator) in hunk.

In case of read error, -1 is returned. In case of having read some data, but encountering EOF before seeing the terminator, the data that has been read is returned, but it will (obviously) not contain the terminator.

The TERMINATOR function is called with three arguments: the beginning of the data read so far, the beginning of the current block of peeked-at data, and the length of the current block. Depending on its needs, the function is free to choose whether to analyze all data or just the newly arrived data. If TERMINATOR returns 0, it means that the terminator has not been seen. Otherwise it should return a pointer to the character immediately following the terminator.

The idea is to be able to read a line of input, or otherwise a hunk of text, such as the head of an HTTP request, without crossing the boundary, so that the next call to RecvRaw() etc. reads the data after the hunk. To achieve that, this function does the following:

Peek at incoming data.
Determine whether the peeked data, along with the previously read data, includes the terminator.

3a. If yes, read the data until the end of the terminator, and exit.

3b. If no, read the peeked data and goto 1.

The function is careful to assume as little as possible about the implementation of peeking. For example, every peek is followed by a read. If the read returns a different amount of data, the process is retried until all data arrives safely.

Reads at most one less than the number of characters specified by maxsize.

Definition at line 1258 of file TWebFile.cxx.

◆ GetLine()

Int_t TWebFile::GetLine	(	TSocket *	s,
		char *	line,
		Int_t	maxsize
	)

protectedvirtual

Read a line from the socket.

Reads at most one less than the number of characters specified by maxsize. Reading stops when a newline character is found, The newline (
) and cr (), if any, are removed. Returns -1 in case of error, or the number of characters read (>= 0) otherwise.

If so, return the pointer to the position after the line, otherwise return 0. This is used as callback to GetHunk(). The data between START and PEEKED has been read and cannot be "unread"; the data after PEEKED has only been peeked.
