similar to: [PATCH 1/6] cmd: add a way to run (and wait) asynchronously commands

Hi, attached there is the second version of the patch series adding copy_in and copy_out in the library, mostly moving them from guestfish. It also adds the copy_in usage in virt-customize, as aid in a new image building. Thanks, Pino Toscano (7): cmd: add a way to run (and wait) asynchronously commands cmd: add a child-setup callback cmd: add the possibility to get a fd to the process

Commits 3c27f3d91e1566854747bbe844186783fc84f3a8 and 1b6f0daa9ae7fcc94e389232d0c397816cda973d added an internal API for running commands asynchronously. It is only used by the copy-in and copy-out APIs. Unfortunately this made the command code very complex: it was almost impossible to redirect stderr to a file, and there were a lot of long-range dependencies through the file. It was also buggy:

Add new optional argument to copy-out: 'numericowner', 'excludes', 'xattrs', 'selinux', and 'acls'. Pass them straight to tar-out, so it is possible to tweak how the files are extracted from the guest, and locally saved. --- generator/actions.ml | 37 +++++++++++++++++++++++++++++++++++-- gobject/Makefile.inc | 2 ++ lib/copy-in-out.c | 29

Currently implemented as guestfish commands, provide them instead as single source -> destination functions for the library, so they can be used also in other places. These functions are not added to guestfish, since guestfish has its own implementation (which will soon switch to call copy-in and copy-out for multiple paths). --- generator/actions.ml | 28 ++++++ po/POTFILES | 1 +

Hi, this patch series does changes mostly in virt-dib, few bug fixes and a couple of new features (mostly implemented upstream already). In addition, one new API is added, and a new optional argument for an existing API is added (the latter is not needed, but could be useful anyway). Thanks, Pino Toscano (10): dib: fix listing envvars in fake-sudo dib: source dib "die" script in

libguestfs has used double and triple underscores in identifiers. These aren't valid for global names in C++. (http://stackoverflow.com/a/228797) These large but completely mechanical patches change the illegal identifiers to legal ones. Rich.

Inspired by libvirt's virCommand* internal mini-library, this adds some internal APIs for running commands. The first patch contains the new APIs. The subsequent patches change various parts of the library over to use it. Rich.

Add a new 'excludes' optional argument to copy-out, passing it straight to tar-out: this way it is possible to exclude files when extracting a directory from the guest. --- generator/actions.ml | 16 ++++++++++++++-- gobject/Makefile.inc | 2 ++ lib/copy-in-out.c | 13 ++++++++++--- 3 files changed, 26 insertions(+), 5 deletions(-) diff --git a/generator/actions.ml

Various changes/fixes to use smaller stack frames. Rich.

After fuzzing 'qemu-img info' I found that certain files can cause the command to use lots of memory and time. Modify the command mini-library to allow us to place resource limits on subprocesses, and use these to limit the amount of space and time used by 'qemu-img info'. --- configure.ac | 3 +++ src/command.c | 53

The latter is a better way to disable the qemu display output as we need to, without enabling extra devices (which are disabled already, anyway). Also, related to the change above, ban the -display parameter from the ones that can be supplied by the user. --- configure.ac | 8 ++++---- src/launch-direct.c | 12 ++++++++---- src/launch.c | 1 + 3 files changed, 13 insertions(+), 8

Hi, things are progressing slowly, but I feel that eventually I'll be getting there: supermin can be built on all Linux-based architectures that are part of Debian/unstable[1] -- (except for sparc, but I'll ignore that for now.) libguestfs on the other hand currently fails launching the appliance (necessary for running tests) on everything but x86 and mips. Apparently, qemu-system-arm

QEMU upstream has broken snapshot=on ... again. These two patches stop using it entirely. Instead we run 'qemu-img create' to create overlay disks as required. Note that the libvirt and UML backends were already doing this: The libvirt backend because <transient/> has never worked, and the UML backend was running uml_mkcow because the UML-equivalent syntax of snapshot=on was

Hello, the package snow is not working on a windows cluster with MPICH2 and Rmpi. There is an error in makeCluster: launch failed: CreateProcess(/usr/bin/env "RPROG="C:\Programme\R\R-2.5.1\bin\R" "OUT=/dev/null" "R_LIBS=" C:/Programme/R/R-2.5.1/library/snow/RMPInode.sh) on 'cl1' failed, error 3 - Das System kann den angegbenen Pfad nicht finden. I

A lot of code runs 'qemu-img create' or 'truncate' to create blank disk images. In the past I resisted adding an API to do this, since it essentially duplicates what you can already do using other tools (ie. qemu-img). However this does simplify calling code quite a lot since qemu-img is somewhat error-prone to use (eg: don't try to create a disk called "foo:bar")

I have a string, "2012_10_16"; let's call this $YESTERDAY How can I rsync a file tree from a remote machine to the local one, including *only* filenames that contain the matching string? I've read the man page and googled around but can't seem to get the syntax right. I either end up syncing all the files, or none of them. Here's how the code looks now (I will remove

select() has a maximum value for the FDs it can monitor, and since the libguestfs library can be used in other applications, this limit may be hit by users in case lots of FDs are opened. As solution, switch to poll(): it has a slightly better interface to check what changed and for which FD, and it does not have a limit in the value of the FDs monitored. poll() is supported on the platforms we
