Dag-Erling Smørgrav 7ca2f6ae1f Fix this my way. David had absolutely no call overriding MAINTAINER without 
even giving me 24 hours to read his mail and find the bug.

David E. O'Brien f18255c68b Install per function manpages so one doesn't mistakenly think we don't 
have manpages for libfetch's functions.

David E. O'Brien f03bce74fc Repeat after me, "check to see that a pointer isn't NULL before 
dereferenceing it".  This fixes ``pkg_add -r''.

Dag-Erling Smørgrav 303fd73aa7 MFS: don't expect result code until you close the data connection 2000-10-27 11:37:21 +00:00
Dag-Erling Smørgrav c7d40ef296 Use funopen() instead of fdopen(). This fixes three problems: 
- ftpTimeout was not honored when reading actual data, as opposed to
   talking protocol

 - connection caching was broken because _ftp_cached_connect() would see
   the result of the transfer instead of the result of the NOOP.

 - if the RETR succeeded, but an error occurred later (as can happen
   when talking to a proxy), the error would not be detected.

There still remains to register an atexit(3) callback to close the cached
connection gracefully instead of just dropping it on the floor.

Dag-Erling Smørgrav 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.

 2000-10-12 16:55:52 +00:00
Dag-Erling Smørgrav a898bb8d0d 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).

Dag-Erling Smørgrav 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.

Dag-Erling Smørgrav 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.

Dag-Erling Smørgrav 10851dc4ad Centralize the default port finding code. 
Work around YA Apache bug: don't send port in Host: header if it's the
default port.
 2000-07-25 11:45:38 +00:00
Dag-Erling Smørgrav 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.

Dag-Erling Smørgrav dfe7c55fcc The decision to use an HTTP proxy for FTP documents belongs in the FTP code 2000-07-21 10:46:22 +00:00
Dag-Erling Smørgrav 2e88106bd1 Don't send port number to proxy unless it's not the standard FTP port 2000-07-21 10:25:33 +00:00
Dag-Erling Smørgrav 5e3f46b51a Fix the case where the file name is preceded by a lone slash. 2000-07-20 02:03:56 +00:00
Dag-Erling Smørgrav 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.
 2000-07-19 23:43:49 +00:00
Dag-Erling Smørgrav 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.
 2000-07-18 07:12:26 +00:00
Dag-Erling Smørgrav 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.

Dag-Erling Smørgrav 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.

Dag-Erling Smørgrav 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.

Dag-Erling Smørgrav 7c80207e33 Remove fetchContentType(), which disappeared in the HTTP rewrite. 2000-07-17 20:42:13 +00:00
