The existing mechanism was clunky, slow and used ~ 10 MB of local disk. Rich.

Hello, I was looking for a way to detect the installed boot loader of an image and I found this: https://github.com/arvidjaar/bootinfoscript This script will inspection a lot of things on a running system and will output a Report. The most interesting part is that it uses known Master and Volume Boot Record byte-patterns to determine the installed boot loader:

This patch adds a new function, guestfs_file_arch, which is like guestfs_file but specifically intended to determine the architecture of binaries and libraries. Usage is: guestfs_file_arch (g, "/bin/ls") ==> "x86_64" (or whatever) What it can do: - ELF binaries - ELF shared libraries - Windows Win32 and Win64 binaries - Windows Win32 and Win64 DLLs - Linux

This patch series changes a small part of the library to use __attribute__((cleanup(...))) to automatically free memory when pointers go out of the current scope. In general terms this seems to be a small win although you do have to use it carefully. For functions where you can completely get rid of the "exit code paths", it can simplify things. For a good example, see the

These three patches (two were previously posted) can do simple operating system inspection in C. Example of use: ><fs> add-ro rhel55.img ><fs> run ><fs> inspect-os /dev/VolGroup00/LogVol00 ><fs> inspect-get-type /dev/VolGroup00/LogVol00 linux ><fs> inspect-get-distro /dev/VolGroup00/LogVol00 rhel ><fs> inspect-get-arch

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

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-

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.

Split up the huge generator/actions.ml into several smaller files. 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.

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
