* Coverity: fix memory leak along error path.Richard W.M. Jones2011-08-281-0/+12
| | | | (cherry picked from commit ce18be33cd5279a8d4120eedd037400c275585c0)
* pclose: Fix other places where we only tested pclose == -1.Richard W.M. Jones2011-08-282-2/+2
| | | | | pclose can return > 0 when the status of the command was non-zero. (cherry picked from commit 631faad97171d7c1238b2e413c663cf61476f440)
* test_qemu: Improve the error message.Richard W.M. Jones2011-08-281-1/+2
| | | | | | Note that errno is probably not set to a useful value here, so there is not much point recording it. (cherry picked from commit f15961911316460f7d45342d63c2d784a483f0d1)
* test_qemu: pclose may return any != 0 on error.Richard W.M. Jones2011-08-281-1/+1
| | | | | In particular pclose returns a status > 0 if the command fails. (cherry picked from commit a24652c7b27e8494268ccb6c9a5a2e5541ba5efd)
* qemu detection: Free up previous qemu help/version strings if they exist.Richard W.M. Jones2011-08-281-0/+5
| | | | (cherry picked from commit 2ace9be4cd69e84cd88e5b0fd74de861a4973c91)
* Coverity: test_qemu: Ensure FILE * is not leaked along error paths.Richard W.M. Jones2011-08-281-15/+21
| | | | | | This refactors the code in test_qemu slightly to ensure that FILE *fp is not leaked on error paths. (cherry picked from commit 08e77ad8cb4e8ac70d4217ebd5d236eba81645b5)
* Escape special/non-printing characters in debug output (RHBZ#731744).Richard W.M. Jones2011-08-281-12/+42
| | | | | | | | | | | | | | | | | | | The default event handler in libguestfs was simply writing all debug output directly to stderr. However if the output contains non-printable characters such as terminal control codes then these would also be sent directly. With newer SeaBIOS there is a lame attempt to implement a splash screen using terminal control codes, thus when libguestfs tries to display debugging output it would cause the screen to clear and debug output to be lost. This commit causes all non-printing characters to be escaped. (\n and \r characters from the appliance are treated somewhat specially). Furthermore, instead of using write(2), use buffered stderr calls. (cherry picked from commit 06019bc82e107f7715ebc59e491610e06dad1e39)
* Remove guestfs___print_timestamped_argv.Richard W.M. Jones2011-08-283-48/+90
| | | | | | | | | | | | | | | | | | | | | | | | This function was used to print the qemu and febootstrap-supermin-helper command lines. Unfortunately in the qemu case it was used incorrectly: it called the internal debug function (ie. event API callback) from the forked qemu subprocess, which meant that higher level event callbacks might have been invoked from the child process. To fix this, convert the qemu case into a new function called print_qemu_command line which just prints the command line directly to stderr. This is called after stderr has been redirected into the pipe to the main process. Thus the qemu command line will be marshalled into the event API along with other qemu and appliance output. After fixing this, only one use of guestfs___print_timestamped_argv remained, for printing the febootstrap-supermin-helper command line. This is converted to a local function print_febootstrap_command_line. Also print_febootstrap_command_line is now called before we fork febootstrap-supermin-helper, so that messages no longer overlap. (cherry picked from commit 635af5be04265f845186b40e9a9fe7b102ad6909)

* inspection: Better checking for Windows root disks (RHBZ#729075).Richard W.M. Jones2011-08-173-30/+75
| | | | | | | | | | | | | | | | | | Previously any disk that had /autoexec.bat or /boot.ini or /ntldr would be picked up as a candidate for a Windows root disk. If further checking could not find any systemroot (eg. /windows) then this would result in complete failure of inspection. In particular, this got confused by Hp_recovery partitions which have /autoexec.bat, but don't have a systemroot in one of the usual places (they have /MiniNT instead). What we do now is to properly investigate all possible systemroot places before deciding this is a Windows systemroot, so the subsequent failure cannot occur. (Thanks to lorimar for reporting this bug). (cherry picked from commit 2c57305f72cd6181d1849ae6e1b892aa01c7f844)
* docs: guestfs_set_out_of_memory_handler returns void, not int.Richard W.M. Jones2011-08-071-2/+2
| | | | | It always has done. The documentation was wrong. (cherry picked from commit 70f44cc0ea0bcdd025ed657461e07f6778be44ba)
* Change link, since PostgreSQL switched to using git.Richard W.M. Jones2011-08-071-1/+1
| | | | (cherry picked from commit 3cf31c2fe0b356ea5c04117c5235b0a3cfe34971)
* Don't fail if HOSTNAME field is missing on Red Hat guests (RHBZ#726739).Richard W.M. Jones2011-08-071-3/+10
| | | | (cherry picked from commit bad3f4b54a959685f3c0697238fc5753096834fb)
* launch: Add qemu_supports_re function.Richard W.M. Jones2011-07-261-0/+43
| | | | | | | | This function is like qemu_supports, but allows us to grep the help text using regular expressions. Note the function is not used yet. (cherry picked from commit 5d7dc0dfb65f367dab3560ee23e404fe21373f45)
* Require PCRE library.Richard W.M. Jones2011-07-2610-51/+24
| | | | | This library is widely available in distros. (cherry picked from commit 41cd0e302d6554facd6b9f7daaa78304361efaef)
* docs: Document FEBOOTSTRAP_KERNEL, FEBOOTSTRAP_MODULES (RHBZ#671082).Richard W.M. Jones2011-07-261-0/+11
| | | | (cherry picked from commit 316817b5ad98e294a9d2498a4403e82911a75b4a)
* blkid: Detect when value not found and return empty string.Richard W.M. Jones2011-07-201-0/+4
| | | | | | | | | | | | | | If the blkid command returns 2, that means the value was not found. Note that this changes the output of the vfs-type API when the filesystem has no type (eg when it is empty). Previously this would return an error. Now it returns empty string "". We did not document this either way. Making it return empty string is consistent with vfs-label and vfs-uuid. This change broke list-filesystems, since that code was assuming that vfs-type could only return a filesystem type or an error.

* Add user cancellation to the C API.Richard W.M. Jones2011-07-154-7/+70
| | | | | | | | | This allows long transfers (FileIn and FileOut operations) to be cancelled by calling the signal and thread safe guestfs_user_cancel function. Most of this commit consists of a multithreaded program that tests user cancellation of uploads and downloads.
* New APIs: set-pgroup, get-pgroupRichard W.M. Jones2011-07-153-6/+26
| | | | | | | | | | | If the pgroup flag is set in the handle, then the qemu and recovery subprocesses are placed in separate process groups. The default is false. The purpose for setting up a process group is that ^C will not be passed from the main process down to these processes (killing them). This allows ^C and other keyboard events to be caught and handled in the main process.
* New API: write-appendRichard W.M. Jones2011-07-141-1/+1
| | | | Append content to the end of a file.
* New API: btrfs-filesystem-resize (RHBZ#721160).Richard W.M. Jones2011-07-141-1/+1

* New API: ntfsresize-opts (RHBZ#685009).Richard W.M. Jones2011-07-121-1/+1
| | | | | | This is a more comprehensive fix for RHBZ#685009. Add a new API which allows the --force flag to be passed, allowing multiple NTFS resize operations in a single session.
* New API: list-dm-devices (RHBZ#688062).Richard W.M. Jones2011-07-121-1/+1
| | | | List device mapper devices.

* New API: inspect-get-icon returns the guest icon.Richard W.M. Jones2011-06-283-0/+474
| | | | | | | | | | This API returns the guest's favicon if found, else an icon representing the guest operating system. Currently supported by this patch: Fedora, RHEL and derivatives, Debian (but not Ubuntu), Windows XP, Windows 7. This also updates virt-inspector to include an <icon> element containing the icon in base64 encoding.
* Change download_to_tmp so it can work with multi-root operating systems.Richard W.M. Jones2011-06-284-104/+98
| | | | | | | | | | | | | | | | The previous guestfs___download_to_tmp function did not handle multiboot correctly. In particular it used the same cache name for downloaded files from different roots, which could have caused things like applications in each root to be confused. This changes the function so that the cache filename is prefixed with the root / fs number, eg. $tmpdir/0-Name instead of $tmpdir/Name. This change also requires the function to return the new name, so all places in the code which called this function had to be updated. This updates and fixes commit 3c1f762abed92f7a358f3bc93e3396d0606b18ad.
* New API: mount-9p lets you mount 9p filesystems (RHBZ#714981).Richard W.M. Jones2011-06-221-1/+1
| | | | The updated patch makes 'options' into an optional parameter.

* protocol: Enhance "unexpected end of file when reading from daemon" error.Richard W.M. Jones2011-06-071-2/+21
| | | | | Make this error more informative, since it is a common error when the appliance fails to start up.

* Fix guestfs___rollback_cmdline when pos == 0.Richard W.M. Jones2011-05-081-1/+1
| | | | | | | | Because of the previous change to size_t, when pos == 0 the loop would wrap around and cause a segmentation fault. This fixes a regression introduced by commit 10167cea98f93a74abe63f0a54d3a662997e7489.
* add-domain: Add allowuuid flag to allow UUIDs to be used for names.Richard W.M. Jones2011-05-061-1/+11
| | | | | | This makes a backwards-compatible change to the add-domain API. If the optional allowuuid flag is true then UUIDs can be used instead of names in the domain name parameter.
* add-domain: Suppress libvirt errors on stderr.Richard W.M. Jones2011-05-061-0/+12
| | | | | | | | | | | Install an error handler on the libvirt error connection so that errors are not printed on stderr (instead they go up through the usual libguestfs error mechanism). Unfortunately this doesn't suppress initial connection error messages to stderr. I cannot see how to do this without affecting the global libvirt error handler, which is not acceptable for a library to be doing.
