1) Implement redirects (or try to, at least).
2) Implement automatic retry after 503 errors when Retry-After is given.
3) Implement a -a flag to enable both of these behaviors.
4) Recognize Transfer-Encoding headers and emit a warning that the file
is likely to be damaged.
5) Bug fix: only write the amount of data we read.
6) Actually document some of these.
7) Fix the usage message to display flags in semi-alphabetical order.
recognize it any more. This makes the following significant changes:
- The main body of the program doesn't know a thing about URIs,
HTTP, or FTP. This makes it possible to easily plug in other
protocols. (The next revision will probably be able to dynamically
add new recognizers.)
- There are no longer arbitrary timeouts for the protocols. If you want
to set one for yourself, use the environment variables.
- FTP proxies are now supported (if I implemented it right).
- The HTTP implementation is much more complete, and can now do restarts,
preserve modtimes, and mrun in mirror mode. It's not yet up to 1.1,
but it's getting there.
- Transaction TCP is now used for sending HTTP requests. The HTTP/1.1 syntax
for requesting that the connection be closed after one request is
implemented.
In all of this, I have doubtless broken somebody. Please test it and tell me
about the bugs.
This will make a number of things easier in the future, as well as (finally!)
avoiding the Id-smashing problem which has plagued developers for so long.
Boy, I'm glad we're not using sup anymore. This update would have been
insane otherwise.
2. Add a -l flag for symlinking to rather than copying file:/path style URLs.
3. Add a -T flag for setting the timeout interval (overrides FTP_TIMEOUT if set)
to 1K to avoid waiting too long between 2 progress reports in the case of a
slow transfer.
Move the signal()/setitimer() code just before the read loop because the
ftpio library set and reset the timer internally.
1. Add a copyright at the top.
2. Make passive and binary modes work with new ftpio semantics.
3. Add a `mirror' (-m) flag which only copies the remote file if it's
not the same size or is newer.
1. Always use file modtime, and if that's not usable then default
to current time.
2. Allow HTTP_TIMEOUT to be set as an environment variable to override
default.
3. Handle SIGTERM.
