b256900d4f Scripts temporarily deregister themselves while executing. This 
allows us to avoid execution loops without having to hack around the
image registration order.

2c569fb240 Allow xfer_open() to take a struct uri as well as a URI string. 2007-06-09 18:20:08 +01:00

1ae549b892 Add our own trivial version of stdarg.h. This makes our build 
entirely self-hosted (which avoids problems when building the same
tree on multiple systems - e.g. when you have /home NFS-mounted).

Also saves around 50 bytes in total - not sure why.

b8618d76db Modify data-xfer semantics: it is no longer necessary to call one of 
request(), seek() or deliver_xxx() in order to start the data flow.
Autonomous generators must be genuinely autonomous (having their own
process), or otherwise arrange to be called.  TCP does this by
starting the retry timer immediately.

Add some debugging statements.

b1755462ab Do not hold self-references. This then avoids the problem of having to 
ensure that we only drop our self-reference exactly once.

To maintain the guarantee that an object won't go out of scope
unexpectedly while one of its event handlers is being called, the
event-calling functions now automatically obtain and drop extra
references.

c42a384709 Moved most buffer debug messages to DBG2. 
Make expand_buffer() a non-inline function, so that we can add debug

Expandable buffers now don't *always* round up to the next power of two.
This allows e.g. loading a 137MB ISO image on a machine with only 256MB
RAM...

c676591cd1 Unmaintained example code is probably worse than useless. 2007-01-15 09:06:12 +00:00
Michael Brown
4e20d73bb5 Gave asynchronous operations approximate POSIX signal semantics. This 
will enable us to cascade async operations, which is necessary in order to
properly support DNS.  (For example, an HTTP request may have to redirect
to a new location and will have to perform a new DNS lookup, so we can't
just rely on doing the name lookup at the time of parsing the initial
URL).

Anything other than HTTP is probably broken right now; I'll fix the others
up asap.
