[Zero-install-devel] 0install 2.11

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

0install 2.11 is now available (source and generic binaries):

  http://0install.net/install-source.html
  http://0install.net/install-linux.html#generic


Since 2.10:

New features

- Add support for PackageKit >= 0.9.1.
  Warning was:

  0install: obus(signal): failed to cast signal from ":1.21",
interface "org.freedesktop.PackageKit.Transaction", member "Details"
with signature "a{sv}" to "ssusst"

- Allow specifying a required implementation exactly. In addition to
version numbers and ranges (e.g. "2.4..!3") you can now require a
particular implementation by its feed and unique ID within the feed.
The syntax is "=FEED/ID", where ID is escaped using the underscore
escaping scheme used elsewhere. This is mostly useful for tools.


Changes

- New layout for $ZEROINSTALL_PORTABLE_BASE:

  Before:
  - config/0install.net/...
  - data/0install.net/...
  - cache/0install.net/...

  After:
  - config/...
  - data/...
  - cache/...

  This is to match the behaviour of the Windows version of 0install
(which was the only thing using ZEROINSTALL_PORTABLE_BASE). Requested
by Bastian Eicher.


Bug fixes

- Fixed error if ~/bin is in $PATH but doesn't exist. Error was:

  $ 0install add app feed
  open_temp_file failed: /home/user/bin/tmp-55724b.new: No such file
or directory

  Reported by Alex Eng.

- Fix "config --dry-run". Error was:

  Bug: 'atomic_write' called in --dry-run mode

- When listing the input files used for a solve, we used the interface
configuration path instead of the feed path (found by the new stricter
Paths code; see below). This meant that we wouldn't automatically
recalculate if the feed settings changed.


Code clean-ups

- Added all solver test cases from the 0install-win tests to the OCaml
code (Bastian Eicher).

- Add Zeroinstall.Paths helpers. This provides a more type-safe API
for reading and writing config, data and cache paths. In particular,
this avoids duplicating the escaping code each time a path is used.

- In --dry-run mode: instead of modifying the existing config object,
create a new one and start again. Avoids having to track down all the
places that may have stashed a copy of the old config. The
config.system field is now immutable.

- Move $ZEROINSTALL_PORTABLE_BASE test from Basedir to Paths. This
doesn't have anything to do with the XDG basedir standard, and
shouldn't affect non-0install paths (e.g. "share/applications").

- Depend on camlp4 in the opam file. It's no longer installed by default.
