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.

v6 was posted here: https://www.redhat.com/archives/libguestfs/2017-June/msg00103.html and this requires the utilities refactoring posted here: https://www.redhat.com/archives/libguestfs/2017-June/msg00169.html Inspection is now complete[*], although not very well tested. I'm intending to compare the output of many guests using old & new virt-inspector to see if I can find any

This is a combination of: https://www.redhat.com/archives/libguestfs/2017-June/msg00046.html [PATCH 00/12] Refactor utility functions. plus: https://www.redhat.com/archives/libguestfs/2017-June/msg00023.html [PATCH v3 00/19] Allow APIs to be implemented in OCaml. with the second patches rebased on top of the utility refactoring, and some other adjustments and extensions. This passes

https://bugzilla.redhat.com/show_bug.cgi?id=1477623 The first two patches are cleanups. The third patch changes the way that we handle Device and Dev_or_Path parameters so that a parameter marked as such can really only contain a block device name (and not, for instance, a chardev). Using a chardev here caused hangs in the API. The next two patches fix API usage to conform to this new stricter

v5: https://www.redhat.com/archives/libguestfs/2017-June/msg00065.html Since v5, this now implements inspection almost completely for Linux and Windows guests. Rich.

v7 was: https://www.redhat.com/archives/libguestfs/2017-June/msg00169.html https://www.redhat.com/archives/libguestfs/2017-June/msg00184.html I believe this addresses all comments received so far. Also it now passes a test where I compared about 100 disk images processed with old and new virt-inspector binaries. The output is identical in all cases except one which is caused by a bug in blkid
