6 guestfs-release-notes - libguestfs Release Notes
7
9 These release notes only cover the differences from the previous
10 stable/dev branch split (1.10.0). For detailed changelogs, please see
11 the git repository, or the ChangeLog file distributed in the tarball.
12 New features
14 guestfish
15 - guestfish strings can use escapes,
17 eg. ><fs> write /foo "line 1\nline 2\n"
18 - guestfish write-append command can be used to append to files.
20 - Long-running file uploads and downloads can be cancelled through the
22 API or by hitting ^C in guestfish.
23 - New guestfish "display" command for displaying graphical files
25 inside guests.
26 - In guestfish, tab completion now works on /dev/mapper devices.
28 virt-inspector
30 - Inspection API can get an icon or logo for certain guests.
32 - virt-inspector includes the logo and hostname for certain guests.
34 - virt-inspector can now get the version and release numbers for RPM
36 packages.
37 - CentOS and Scientific Linux are now treated as separate distros by
39 the inspection API.
40 virt-resize
42 - virt-resize can now handle btrfs.
44 - New virt-resize --ntfsresize-force option allows Windows VMs to be
46 resized multiple times.
47 other virt tools
49 - guestfish, guestmount, virt-cat, virt-df, virt-edit, virt-filesystems,
51 virt-inspector, virt-ls and virt-rescue now allow you to use
52 "-d UUID" option to specify a guest by UUID. This makes them more
53 robust to use from other programs.
54 - virt-ls -lR option allows complex file iteration and guest analysis.
56 - virt-win-reg supports HKEY_USERS\<SID> and HKEY_USERS\<username>.
58 - virt-win-reg new option --unsafe-printable-strings allows printable
60 strings to be displayed in the output (unsafely: read the documentation
61 before using).
62 - virt-edit has been rewritten in C.
64 API and language bindings
66 - Java is now completely supported.
68 See http://libguestfs.org/guestfs-java.3.html
69 - JRuby is supported via the Java bindings.
71 - guestfs_close now appears in trace messages.
73 - Python binding adds explicit g.close() method.
75 - Python programs can now use the new event API.
77 - Python GIL is released during libguestfs calls, allowing multithreaded
79 Python programs to work properly.
80 - 9pfs (Plan 9 filesystems exported from the host) are now supported.
82 - Add -DGUESTFS_WARN_DEPRECATED=1 to warn about use of deprecated API
84 functions in C programs.
85 - New manual page guestfs-recipes(1) with recipes.
87 - mkfs-opts can now set inode size and sector size on created filesystems
89 (thanks Nikita Menkovich).
90 - guestfs_last_errno is now accessible from OCaml (as g#last_errno ()).
92 Security
94 - optargs_bitmask is checked even for calls that have no optional
95 arguments. This closes a possible exploit in the daemon from
96 untrusted callers.
97 New APIs
99 btrfs-filesystem-resize, get-pgroup, inspect-get-icon, is-zero,
100 is-zero-device, list-9p, list-dm-devices, mount-9p, ntfsresize-opts,
101 set-pgroup, write-append
102 Internals
104 - Coverity (a static analysis tool) was run across the codebase and
105 many fixes were made.
106 - Generator can handle functions that return RBufferOut and have
108 optional arguments.
109 - Compatible with Perl 5.14.
111 - Compatible with gcc 4.6.
113 - Perform safety checks on QEMU.
115 - C API tests can now fully test calls that have optional arguments.
117 - Use ./configure --enable-install-daemon to install /usr/sbin/guestfsd.
119 - po-docs directory now covers all man pages.
121 - stderr from qemu process is now captured by the event subsystem.
