v3 was here: https://www.redhat.com/archives/libguestfs/2019-November/msg00209.html In v4: - Rebase on top of current master. Includes various fixes and updates required because of Nir's patches that went into master. - Fix api_version() -> API_VERSION in patch 2 noted previously on the mailing list. Rich.

v2 was here: https://www.redhat.com/archives/libguestfs/2019-November/msg00163.html I pushed patch 1 (with spelling fix), patch 4 and patch 5 since those were previously ACKed on the list. Differences in v3: - Add error checking to PyModule_AddIntConstant. - Use API_VERSION constant instead of function. - Add max API version supported to --dump-plugin output. - Print API_VERSION selected by

Just a quick update, I''ve dropped the hashing stuff in favor of doing a memcmp in the kernel to make sure the data is still the same. The thing that takes a while is reading the data up from disk, so doing a memcmp of the entire buffer isn''t that big of a deal, not to mention there''s a possiblity for malicious users if there is a problem with the hashing algorithms we

Rewrite btrfs_drop_extents by using btrfs_duplicate_item, so we can avoid calling lock_extent within transaction.

As suggested by Nir, here: https://www.redhat.com/archives/libguestfs/2019-November/thread.html#00220

These are accessible from the plugin by: import nbdkit if flags & nbdkit.FLAG_MAY_TRIM: &c. Many (all?) of these are not yet useful for plugins, some will never be useful, but they only consume a tiny bit of memory and it's nice to have the complete set available for future use. --- plugins/python/python.c | 27 +++++++++++++++++++++++++++ 1 file changed, 27 insertions(+)

And fill out most of the missing bits of the API. Rich.

v1: https://www.redhat.com/archives/libguestfs/2019-November/msg00153.html v2: - Fix implementation of can_cache. - Add implementation of can_fua. - Add a very thorough test suite which tests every command + flag combination.

This picks up python and ocaml. Some of our languages are lacking a number of bindings (for example, lua and perl lack .extents, so I didn't have anything to copy from), and I felt less comfortable with golang and rust. But for python and ocaml, I was able to test a working implementation. Eric Blake (2): python: Implement .list_exports and friends ocaml: Implement .list_exports and

Here are patches to do offline deduplication for Btrfs. It works well for the cases it''s expected to, I''m looking for feedback on the ioctl interface and such, I''m well aware there are missing features for the userspace app (like being able to set a different blocksize). If this interface is acceptable I will flesh out the userspace app a little more, but I believe the

The following series implements libxl_domain_config_init as per the libxl API requirement that each type has an init function. The first function does this in an open coded manner and is proposed for Xen 4.2. The second function is RFC only since it moves the definition of this type into the IDL and makes the required infrastructure updates to enable this. I think this is more 4.3 material at

We''re going to use this flag EXTENT_DEFRAG to indicate which range belongs to defragment so that we can implement snapshow-aware defrag: We set the EXTENT_DEFRAG flag when dirtying the extents that need defragmented, so later on writeback thread can differentiate between normal writeback and writeback started by defragmentation. This patch is used for the latter one. Originally patch

I will be following up to this email with four separate threads each addressed to the appropriate single list, with proposed changes to: - the NBD protocol - qemu: both server and client - libnbd: client - nbdkit: server The feature in question adds a new optional NBD_INFO_ packet to the NBD_OPT_GO portion of handshake, adding up to 16 bits of information that the server can advertise to the

Changes since last time: - split auto-generated code in to c and h files - un-break the build system - fix ocaml binding due to libxl API change - lot''s of tidy-ups too numerous to mention Please consider and apply :) -----8<--------------------------------------------------------------- Introduce python binding for libxl. The binding is not yet complete but list_domains,
