[Zero-install-devel] 0install 2.6-rc2

[Thomas L. <ta...@gm...>]

Here's a second release candidate for 0install 2.6 (2.6-rc2):

  http://0install.net/tools/0install.xml

0install 2.6 completes the transition from Python to OCaml :-) There
is no remaining Python code in 0install and, therefore, no need to
have Python installed in order to build or run it.

Notes:

0install now runs the unit-tests when you build it, and will abort if
they fail. Please report any problems. You can remove "test" from the
"all" target in ocaml/Makefile if it's a problem for you (also, the
tests are only run if oUnit is installed).


Changes since 2.6-rc1

- On non-Linux platforms, use Lwt_glib's lwt_into_glib mode. This
requires a Git checkout of LWT, but that's better than the other
option, which doesn't work at all. Note: if you don't build the GTK
GUI, there's no problem (and therefore Windows is unaffected, as it
never builds the GUI).

- Fixed race when cancelling downloads. The main thread might set the
progress report to "finished" and then the download thread gets some
more data and sets it back to "in-progress" before the cancel takes
effect. This meant that the GUI would continue showing the progress
bar even after cancelling.

- Don't strip the 0install binary. That prevents the GTK plugin from
loading on OS X. Reported by Anders F Björklund.

- Detect Python even if python-gobject is missing. Reported by Anders
F Björklund.

- Some internal code cleanups: there are .mli interfaces for more
modules and the APIs have been cleaned up a bit (the biggest change is
that XML elements are now immutable, and can therefore be safely
shared).


Changes since 2.5

New features:

- Added "0install slave" subcommand. This makes it possible to control
0install using a JSON API. The "sample_client.py" file shows how to
invoke 0install from Python. Currently, the only operation available
is "select", which downloads feeds and does a solve, but more can be
added - let me know what you need.


Changes:

- Migrated GTK GUI to OCaml. It mostly looks the same, but the
"0desktop" box has changed to a more compact icon view display. Also,
displaying the app list is now the default (and the 0desktop --manage
option is gone).

- The console progress display has changed slightly: it now shows the
progress of one download at a time rather than all at once. The
downloads still happen in parallel, though.

- The install script now allows using $DESTDIR and installing to
/usr/local (Anders F Bjorklund).

- You can now do "0install store ..." instead of "0store ..." (which
still works). If you do this, you get tab-completion too!


Bug fixes:

- Cope with dpkg-query returning a non-zero exit status. It returns 1
if the package isn't found.

- Fixed cancelling of downloads. Throwing an exception back to ocurl's
set_writefunction handler left the connection in a bad state.

- Fixed Utils.slice when start and end are both given (Tim
Cuthbertson) (this case was never used by the current code).

- Fixed unit-tests when $TEMP is a symlink. Reported by Anders F Björklund.

- Don't use the non-portable -D flag to install (Anders F Bjorklund).
To make it work with BSD install(1) in addition to GNU install(1),
make sure to use "install -d && install" rather than install -D.

- Fixed installation error when share/0install.net doesn't exist.
Reported by Alberto Colombo.

- Don't warn about the default bin dir not being in PATH when destroying an app.


Developer-visible changes:

- Pick a random unused port for the test server during unit-testing.
Avoids conflicts with other programs and makes it possible to run the
tests in parallel.

- If $ZEROINSTALL_CRASH_LOGS is set to a directory, record all log
messages in memory. If 0install logs a warning or reports an error,
dump the complete log to a timestamped file in this directory.
