Initial discussion is here: https://www.redhat.com/archives/libguestfs/2018-January/msg00188.html. v2 was posted here: https://www.redhat.com/archives/libguestfs/2018-January/msg00246.html. v3 comparing to v2 is just a rebase with slightly changed commits comments.

Instead of parsing 'parted' output OCaml implementation relies on the following facts: 1. The function is applicable for MBR partitions only (as noted in documentation and as function name suggests). 2. An attempt to call the function for non-MBR partition fails with "part_get_mbr_part_type can only be used on MBR Partitions" error and NULL is returned. 3. MBR partition table

This patch series: 1. Addresses comments from last review: part_get_mbr_part_type doesn't break original implementation in C. 2. Rebased on top of master and little bit refactored for readability. Mykola Ivanets (1): tests: md: Test guestfish list-filesystems command skips partitioned md devices. Nikolay Ivanets (2): daemon: Reimplement 'part_get_mbr_part_type' API in

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: https://www.redhat.com/archives/libguestfs/2015-December/msg00038.html Inspection now really succeeds on a small number of simple guests. To test it out: $ ./run guestfish -v -x -a /tmp/centos-6.img ><fs> run ><fs> debug sh "guestfs-inspection --verbose" Rich.

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.

This is a more working version. Inspection (partially) succeeds on a real guest this time :-) You can test it out on a real guest (in this case, a CentOS disk image located at /tmp/centos-6.img) by doing: $ ./run guestfish -v -x -a /tmp/centos-6.img ><fs> run ><fs> debug sh "guestfs-inspection --verbose" which will print lots of debugging, and at the end the

For background on this change, see: https://rwmj.wordpress.com/2015/12/06/inspection-now-with-added-prolog/ v2 was previously posted here: https://www.redhat.com/archives/libguestfs/2015-December/msg00038.html To test this patch series on a real guest, you can do: $ ./run guestfish -v -x -a /var/tmp/centos-6.img ><fs> run ><fs> debug sh "guestfs-inspection

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

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

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.
