* trace: Fix escaping of non-printable signed characters.Richard W.M. Jones2012-06-011-1/+1

* inspection: Don't fail if /etc/HOSTNAME or /etc/hostname are empty files ↵Richard W.M. Jones2012-06-012-4/+24
| | | | | | | | | | | | | | | | | | | (RHBZ#823821). Change guestfs___first_line_of_file so that if the file is empty this returns an empty string instead of an error. This is consistent with the behaviour of this function in the case where the file starts with a \n character, where it would previously have returned an empty string. Change all callers so that they handle this case. Then change the hostname parsing code so that it doesn't give up when /etc/HOSTNAME is empty, but falls through to the next alternative, and similarly for /etc/hostname. Thanks Todd Mummert for finding and diagnosing this bug. (cherry picked from commit f00066d22b11bf40d0272f68565a2a27fea15627)
* inspection: Use parse_release_file to parse ttylinux release file.Richard W.M. Jones2012-06-011-2/+1
| | | | | | | | | | parse_release_file should be used to set fs->product_name, instead of calling guestfs___first_line_of_file directory, although currently the two are equivalent. This is code motion and fixes commit b648b1813fc8e55db790435b5414d9be3ec765d2. (cherry picked from commit cffb7fefc88a317f957785f6448fb24183c8c629)
* qemu: Move -nodefaults etc logically together.Richard W.M. Jones2012-05-141-13/+16
| | | | | | This is just code motion. (cherry picked from commit 157f6fb18b7197f688ea761a4e52cd39287024f2)
* arm: Set minimum LIBGUESTFS_MEMSIZE at 128.Richard W.M. Jones2012-05-141-1/+1
| | | | | | | | | For ARM Versatile ("versatilepb") architecture, memsize must be set to 256 (megabytes) else the appliance is unable to boot. Previously setting LIBGUESTFS_MEMSIZE=256 was not allowed. Versatile Express has larger limits. (cherry picked from commit a3718c6b8be9bcbfd1e753c699f030d1852bc26e)
* configure: Allow systemtap/DTrace userspace probes to be disabled.Richard W.M. Jones2012-05-141-2/+2
| | | | | | | | | | './configure --disable-probes' will disable these probes. Otherwise they are autodetected as before. The <sys/sdt.h> produces lots of errors when you try to compile with these probes enabled under clang, so it is necessary to provide a way to disable them for clang users. (cherry picked from commit a1680f03b7d38bf007d29ac23035e5af33736b0e)
* doc: Rewrite description section in man page guestfs(3).Richard W.M. Jones2012-05-011-31/+12
| | | | | | Make the introduction in the man page shorter and punchier, so it leads readers directly to other pages of interest. (cherry picked from commit 922052c70fdc66859c78bbc89a7817aad141862a)
* Move 'libguestfs.pc' (pkgconfig file) to src/ directory.Richard W.M. Jones2012-05-012-0/+17
| | | | | Since it describes the C library, it's better in the src/ directory. (cherry picked from commit bb73cf0941ba9d34eb2ecf82d10ecb5fc5d2362d)

| | | | | Cherry picked from commit 307e8bc51a7416fa62ec43568cb8ba1876490a62 and modified to make it appropriate for the stable-1.16 branch.
* launch: Set error when qemu fails early during launch (RHBZ#811650).Richard W.M. Jones2012-04-111-1/+4
| | | | | | This caused the Python bindings (and probably others) to segfault because guestfs_last_error(g) would return NULL. (cherry picked from commit 0f7de2279a4af0bb259c9e36fca5e5c3aa835301)
* inspection: Support Fedora 17+ (RHBZ#809361).Richard W.M. Jones2012-04-031-2/+5
| | | | | | Recognize grub2 as a bootloader, and /bin being a symlink to /usr/bin (ie. UsrMove feature added in Fedora 17+). (cherry picked from commit 5c8a241e5cd119f436a050ddbbf7ea73f83ff8e4)

| | | | (cherry picked from commit f2fae5151f33e933f4d574dc4324b7a8a2ee393c)
* inspection: Set last errno to ENOTSUP when inspection APIs are not available.Richard W.M. Jones2012-03-211-1/+1
| | | | | | | | | | | | | | | | Previously there was no programmatic way to tell if inspection APIs were unavailable because they are not compiled in (because hivex isn't around). This contrasts with daemon APIs where the availability is covered by the guestfs_available API. Change the inspection APIs so that when they are not available, the last errno is set to ENOTSUP. (Note that ENOTSUP must be defined on all POSIX platforms). This allows programs to detect if they are using a version of libguestfs that was compiled without support for inspection, without having to parse error messages.

* inspect: Ignore missing HKLM\SYSTEM\MountedDevices (RHBZ#803664).Richard W.M. Jones2012-03-161-4/+6
| | | | | | | When a Windows guest doesn't have a HKLM\SYSTEM\MountedDevices node, inspection fails. However inspection should not completely fail just because we cannot get the drive letter mapping from a guest. (cherry picked from commit 91cede3465cd2496a01a89d5c8815df7c326c2ec)
* Fix strict-overflow bugs and reenable this warning.Richard W.M. Jones2012-03-131-3/+3
| | | | | | | | | In two places, we were counting things in an array using an 'int'. In theory, the int could overflow, so gcc determines this to be undefined behaviour. The fix is to use size_t or ssize_t instead. (cherry picked from commit d66dd2260c724bdfe57a8595aac37c8e9173cee5)

* Close all file descriptors and remove all signal handlers in the recovery ↵Richard W.M. Jones2012-03-131-0/+25
| | | | | | | | | | | | | | | | | | process. If the parent process uses a pipe (or any fd, but pipes are a particular problem), then the recovery process would hold open the file descriptor(s) of the pipe, meaning that it could not be fully closed in the parent. Because the recovery process doesn't use exec(2), this wasn't avoidable even using FD_CLOEXEC. Avoid this by closing all file descriptors when starting the recovery process. After discussion with Dan Berrange, he points out that it's also a good idea to set signal handlers to the default after forking, so that any signal handlers set up in the parent don't affect the child.

* Add a 'fixed' style of appliance.Richard W.M. Jones2012-03-031-3/+33
| | | | | | | | | | | This is just the 'kernel', 'initrd' and 'root' files, copied from one machine to another, along with a 'README.fixed' file which is also used for identification. This allows the appliance to be copied from one machine to another, making it easier for us to distribute a starter appliance for people who cannot get febootstrap or appliance-building working.

* appliance: Make appliance building thread-safe (RHBZ#790721).Richard W.M. Jones2012-03-011-1/+12
| | | | | | | | | | | | | | | | Appliance building can be called from multiple processes, but this is only safe if each process holds a lock on the 'checksum' file. However threads within a process are not excluded by a file lock, and so this strategy completely failed for a multithreaded program calling guestfs_launch in parallel. Since it makes no sense for threads in a single program to race each other to try to create the appliance, add a lock around appliance building. This serialises building the appliance, but the rest of guestfs_launch (eg. starting up qemu) can run in parallel. (cherry picked from commit afed7e493dcd594620f19b93e9fb73e58553f60a)

* Enable running the daemon under valgrind.Richard W.M. Jones2012-01-242-0/+18
| | | | | | | | | | | | | | | | | | This commit allows you to run the daemon under valgrind. You have to enable it at configure time: ./configure --enable-valgrind-daemon This should *not* be done for production builds. When this feature is enabled, valgrind is added to the appliance and the daemon is run under valgrind. Log messages from valgrind are passed back over a virtio-serial channel into a file called 'valgrind.log.$PID' in the top build directory. Running 'make check', 'make extra-tests' etc causes many valgrind.log.* files to be created which must be examined by hand. (cherry picked from commit d08806adfc5d111b4b6c761540ff508d3f25b66e)
