6fe9a920d1 Work around buggy servers such as NCSA httpd which send an incomplete 
HTTP-Version on the Status-Line (see RFC2616 sections 3.1 and 6.1).

0247d400b1 Don't fail if _ftp_stat() reports a protocol error, since that most likely 
means that the server doesn't understand SIZE or MDTM, which should not be a
hard failure.

e534b00520 If the server reports the size as 0, treat it as unknown. This works around 
a bug in some ftp servers (most notably ftp.vmunix.com) which report the
size of a file correctly in ascii mode, but report it as 0 in binary mode.

Reported by:	asmodai

Also remove an unneeded initialization.

2de7b8d72b Centralize the default port finding code. 
Work around YA Apache bug: don't send port in Host: header if it's the
default port.

accb02b55a Ignore environment variables that are set but empty. 
Sort out the size / length confusion.  Always try to report the *real* file
size in the url_stat structure, no matter how much of it is actually being
sent, and try to detect inconsistencies between sizes.

Rearrange the request loop to avoid having to add meaningless code just to
silence compiler warnings.

Switch to a more sensible and consistent interface for the _http_parse*()
functions.

adc026dc20 Don't try to skip to the requested offset if the server returns more data 
than requested.  Instead, inform the caller of the real offset by modifying
the offset field in the original struct url, and let him decide how to handle
the situation.

c5e4329667 Don't take a failure to stat a file to mean that it doesn't exist, as it may 
be a dynamically created file, e.g. a tarball on servers that support sending
tarballs of directories.

3033318809 Introduce fetchXGet*(), which combine the functionalities of fetchGet*() and 
fetchStat*().  In most cases, either fetchGet*() or fetchXGet*() is a wrapper
around the other; in all cases, calling fetchGet*() is identical to calling
fetchXGet*() with the second argument set to NULL.

des
9e42d615d8 Don't forget to set file descriptor to -1 after closing it, since the code 
outside the loop inspects it to determine whether or not we succeeded in
retrieving the requested document. This fixes a bug where fetchGetHTTP()
would return a FILE with an invalid file descriptor if it hit the redirect
limit without locating the requested document.

a0fbdfaa34 Don't forget to declare fetchRestartCalls. 2000-07-17 20:52:06 +00:00
des
c1df3803c6 Introduce the (undocumented) variable fetchRestartCalls, which controls whether 
or not interrupted system calls will be restarted. This fixes a bug where
fetch(1) would hang (potentially forever) if a server stopped responding,
because the signal handler would absorb the user's efforts to interrupt the
transfer.

797b7f6ddd Fix a bug (misplaced continue) that caused redirects to fail. Lots of code 
moved around, but the acutal functional changes are small.

59adaf8069 Extensive rewrite of the HTTP code. The new code is significantly cleaner and 
more robust, and somewhat more efficient. It also handles authorization and
redirects properly, and supports timeouts like the FTP code.

Many thanks to Umemoto-san for his assistance with IPv6 support, both here
and in other parts of libfetch.
