These 3 patches implement support for APIs which must accept a mountable, but don't update apis which must return mountables. Matt

The two patches attached allow 9p filesystems to be mounted and listed. Note that I did *not* test the new list-9p function, because I don't have a guest with a new enough kernel handy. 9p filesystems are not included in the output of list-filesystems. Because a lot of existing code feeds the output of list-filesystems directly into the input of mount-options, mount-ro or (even worse) plain

[PATCH 1/7] mount: Add mount_vfs_nochroot This is significantly reworked from before. umount is gone as discussed, and variable motion is minimised. [PATCH 2/7] btrfs: Update btrfs_subvolume_list to take Already provisionally ACKed. Previous comment was that cleanup could be tidier. I looked into creating a new cleanup function for fs_buf, but it isn't possible (or simple, anyway) in this

I ran the Coverity static analyzer[1] on libguestfs, and fixed many errors as a result. Coverity found some errors in gnulib, but it doesn't seem to be worth following those up since the version of gnulib we are using is so old. There are a couple more errors (possibly 1 false-positive) which I'm going to send in a separate email. BTW all the errors found by Coverity were in the daemon

This started as a simple warning-elimination change. I'll get back to that series shortly ;-) It turned into a factorization and constification exercise during which I got a taste of ocaml. Thanks to Rich Jones for help with a few snippets in generator.ml. The overall result is that many previously-manually-maintained bits from daemon/*.c functions are now hoisted into the automatically-

This is a series of simplifications to the stubs code. It's all refactoring, there is no functional change. Rich.

Version 1 was here: https://www.redhat.com/archives/libguestfs/2017-June/msg00003.html This patch series reimplements a few more APIs in OCaml, including some very important core APIs like ?list_filesystems? and ?mount?. All the tests pass after this. The selection of APIs that I have moved may look a little random, but in fact they are all APIs consumed by the inspection code (and some more

v2 was here: https://www.redhat.com/archives/libguestfs/2017-June/msg00008.html This series gets as far as a working (and faster) reimplementation of ‘guestfs_list_filesystems’. I also have another patch series on top of this one which reimplements the inspection APIs inside the daemon, but that needs a bit more work still, since inspection turns out to be a very large piece of code. Rich.

I think this fixes everything mentioned: - Added the Optgroups module as suggested. - Remove command temporary files. - Replace command ~flags with ?fold_stdout_on_stderr. - Nest _with_mounted function. - Rebase & retest. Rich.

v1 was posted here: https://www.redhat.com/archives/libguestfs/2017-July/msg00098.html This series now depends on two small patches which I posted separately: https://www.redhat.com/archives/libguestfs/2017-July/msg00207.html https://www.redhat.com/archives/libguestfs/2017-July/msg00209.html v1 -> v2: - Previously changes to generator/daemon.ml were made incrementally through the patch

Previously posted as part of the mega utilities/inspection series here: https://www.redhat.com/archives/libguestfs/2017-June/msg00232.html What I've done is to extract just the parts related to rewriting daemon APIs in OCaml, rebase them on top of the current master, fix a few things, and recompile and test everything. Rich.
