1a16ed4c9c Rework proxy handling so that proxies can be specified as URLs. 
As a side effect, remove a lot of duplicate and now redundant code.

0f27c7838c 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.

63428824c9 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.

10851dc4ad Centralize the default port finding code.

default port.

c78f1cc912 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.

87b41116cc 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.

269532d987 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.

1a5faa1061 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.

c789727701 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.

d999dcac2d Don't forget to declare fetchRestartCalls. 2000-07-17 20:52:06 +00:00
Dag-Erling Smørgrav
a1bb3f482a 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.

f4683775d7 Fix a bug (misplaced continue) that caused redirects to fail. Lots of code 
moved around, but the acutal functional changes are small.
Add support for site-internal redirects (where the Location: header gives a
path instead of an absolute URI)

e4878e39a3 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.
