5 days agolib/addr.c: Handle `AF_UNIX' sockets in `netaddress_resolve'. master

lib/addr.c: Handle `AF_UNIX' sockets in `netaddress_resolve'.

A `netaddress' is supposed to permit Unix-domain sockets, but this
doesn't actually work in most places because addresses need resolving
before use, and `netaddress_resolve' just delegates to `getaddrinfo',
which doesn't understand Unix-domain sockets at all.

Fix this by synthesizing an appropriate `struct addrinfo *' list if the
address family is `AF_UNIX'.

Previously, the `-' syntax was an undocumented (and booby-trapped) way
to inform the rest of the program that it should request a unicast
stream.  If we see this, then we apply some heuristics to select an
interface to bind to, and ask the server to hurl packets at it.

This is unsatisfactory.  One might want to set a particular port, say
because other ports are firewalled off by default.  And one might want
to set a particular address if the heuristics go wrong.

As a first step, overhaul the command-line parser to accept an address
and port name/number.  We still apply the old heuristics if no address
is provided explicitly, and we get the kernel to select a port number if
none is given.

to be a useful intermediate state.  Sorry.

The old `debian/rules' was a nightmare.  Modern Debhelper is really
quite pleasant, and makes short work of jobs which the old do-it-all-by-
hand script made a horrible meal out of.  Really, the diffstat summary

29 files changed, 146 insertions(+), 440 deletions(-)

says everything I need to know.

Being fair, though, this is quite an overhaul, but I've tried hard to
minimize the fallout.  These are the user-visible changes that I'm aware
of.  Any other changes are unintentional bugs.

  * The `disorder-server' cron script has changed name from
    `/etc/cron.daily/disorder' to `.../disorder-server'.  I could have
    avoided this, but I decided that it was actually better like this.
    The package scripts include the necessary machinery for renaming the
    configuration file.

  * I'm using `dh_installdocs' now, and it has its own heuristics about
    whether to compress documentation files.  As a result, a number of
    the smaller files in `/usr/share/doc/disorder' are no longer
    compressed.  Maybe some users will have to adjust bookmarks or
    something; if this breaks scripts, then I'm afraid that dealing with
    the wreckage is what you signed up for when you wrote those scripts.

Internally, the differences are more significant.

  * A number of affordances for configuring the Debian build have been
    removed or changed; I'm not going to make a list, mostly because the
    `debian/rules' file is now so trivial.  I'm inclined to say that
    retaining these would have been a bad idea.  I view the Debian
    packaging as a route to a stable, standard binary package, best
    built in a fresh, clean, minimal environment provided by something
    like `sbuild'.  I don't object to nonstandard packages at all: I
    just think they're best made and maintained by actually patching the

  * I've added `#DEBHELPER#' markers to the package scripts, and deleted
    some of the smaller ones entirely.  Debhelper doesn't make a whole
    lot of difference to the `disorder-server' postinst script, which is
    the big one, but losing the `disobedience' scripts is a clear win.

  * Debhelper wants to run `make check' during the package build.  I
    think this is a good idea, but it involves a little extra work.
    Because `sbuild' by default forces `LC_ALL' to `POSIX', the
    `' test fails about half the time; overriding `LC_ALL' to
    `C.UTF-8' in `debian/rules' hacks around this.  The `t-addr' library
    test wants to check resolution of service names, which introduces a
    build-dependency on `netbase' to provide `/etc/services'.  I would
    have had to include a dependency on `wget', but I chose to include

Rather than fetch the files using `wget' at test time, fire up `gzip' to
decompress them from local copies.  The files compress really rather
well, so this is an overall saving in disk space relative to the
previous version -- especially since we now share the test files among
all build trees rather than having a separate copy in each.  On the
other hand, they're moderately large things to have in the source
distribution, though small compared to the `images/' tree.

Of course, the main reason for doing this is to completely eliminate the
need for external network connectivity during a build.

to be compatible with the GPL (which is good, because I think we'd have

disobedience/choose-search.c: Fix segfault when search terms change.

The observed problem:  Sometimes, when typing search terms into the box,
DisObedience crashes.  This seems to happen more often when the server
is slow to respond.

Here's what's going on.  Suppose that a search finds some results.  Then
`choose_make_visible' tries to expand the tree to display them.  If some
of the results aren't populated in the tree yet, then
`choose_make_one_visible' arranges to fetch the necessary information
from the server and informs its caller, `choose_make_visible', that
it'll have to try again later.  When this happens, `choose_make_visible'
hooks itself onto the `choose-more-tracks' event and waits for the
information to arrive.

Suppose that, while this is happening, the user edits the search terms;
a new search starts, but this one returns no results.  Then
`choose_search_completed' zaps the `choose_search_results' vector and

Now the metadata from the old search arrives from the server;
`choose_make_visible' is called back.  There are now no search results,
so it thinks its work is done and tries to scroll the list widget so
that the first result is visible -- but the result vector has been
clobbered.  Result: misery.

To fix this, cancel the `choose-more-tracks' event handler when a new
search finishes.  Now we can't get into this situation any more.
