|
* New APIs: isoinfo and isoinfo-device.Richard W.M. Jones2012-03-161-1/+1
| | | | | Get ISO primary volume descriptor information for either ISO devices or ISO files.

* New API: zero_free_space: zero free space in a filesystem.Richard W.M. Jones2012-03-151-1/+1
| | | | | | | | | | | | | | Add an API for doing what virt-sparsify was doing: freeing up free space in a filesystem. The current implementation is simple-minded: we create a file, fill it with zeroes until we run out of space, then delete the file. However the description leaves it open to do a better implementation, eg. using sparsification support that is currently being worked on in ext4 and qemu. The implementation also sends progress notifications, which is an advantage over the old 'dd' method.
* inspect: Ignore missing HKLM\SYSTEM\MountedDevices (RHBZ#803664).Richard W.M. Jones2012-03-151-4/+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.
* Use O_CLOEXEC / SOCK_CLOEXEC for almost all file descriptors.Richard W.M. Jones2012-03-146-11/+19
| | | | | | | | | | | | | | | | | | | | | | | | The presumption is that all file descriptors should be created with the close-on-exec flag set. The only exception are file descriptors that we want passed through to exec'd subprocesses (mainly pipes and stdin/stdout/stderr). For open calls, we pass O_CLOEXEC as an extra flag, eg: fd = open ("foo", O_RDONLY|O_CLOEXEC); This is a Linux-ism, but using a macro we can easily make it portable. For sockets, similarly: sock = socket (..., SOCK_STREAM|SOCK_CLOEXEC, ...); For accepted sockets, we use the Linux accept4 system call which allows flags to be supplied, but we use the Gnulib 'accept4' module to make this portable. For dup, dup2, we use the Linux dup3 system call, and the Gnulib modules 'dup3' and 'cloexec'.
* Replace 'int' with 'size_t' passim.Richard W.M. Jones2012-03-131-1/+1
| | | | | Analyze all uses of 'int' in the code, and replace with 'size_t' where appropriate.
* Fix strict-overflow bugs and reenable this warning.Richard W.M. Jones2012-03-121-3/+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.
* inspect: Move variable decl to top of function.Richard W.M. Jones2012-03-121-1/+3
|
* inspect: Use 1/0 instead of true/false, and fix a bug in UUID parsing.Richard W.M. Jones2012-03-121-9/+13
| | | | | UUID parsing returned 'false' (ie. 0 == OK) when the UUID contained illegal characters. Now it returns -1 == failure.
* lib: Remove some unused variables.Richard W.M. Jones2012-03-124-7/+1
|
* lib: Use size_t instead of int for array iterator.Richard W.M. Jones2012-03-121-1/+1

* lib: Use size_t for allocation size in safe realloc function.Richard W.M. Jones2012-03-122-2/+2

* Close all file descriptors and remove all signal handlers in the recovery ↵Richard W.M. Jones2012-03-091-0/+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.

* inspection: Add detection of FreeDOS (RHBZ#786215).Richard W.M. Jones2012-03-076-0/+24

* Hide stderr of bmptopng.Richard W.M. Jones2012-03-071-2/+3

* build: Make netpbm and icoutils into proper optional dependencies.Richard W.M. Jones2012-03-071-5/+30
| | | | | | | | Netpbm and icoutils (wrestool) have always been dependencies. Since they are not always present, make these into optional dependencies (which they were, sort of, before). Also document these dependencies in the README file.
* Add support for Buildroot and Cirros distributions.Richard W.M. Jones2012-03-075-0/+84

* Whitespace change.Richard W.M. Jones2012-03-071-1/+1
|
* 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.
* Rebrand 'ordinary appliance' as 'old-style appliance'.Richard W.M. Jones2012-03-032-8/+8
| | | | This is just code motion.
* New API: set-label, for setting a label on any filesystem.Richard W.M. Jones2012-02-271-1/+1
| | | | | | Currently only ext2/3/4 and (newly) NTFS are supported. This change also deprecates set-e2label.
* New APIs: ntfsclone-in, ntfsclone-out.Richard W.M. Jones2012-02-271-1/+1
|
* New API: ntfsfix for fixing problems on NTFS.Richard W.M. Jones2012-02-271-1/+1
| | | | Note this is not a "chkdsk" equivalent tool.
* set-smp: limit the number of cpus below 255Wanlong Gao2012-02-251-1/+4
| | | | | | Limit the number of cpus below 255, since qemu can't support. Signed-off-by: Wanlong Gao <gaowanlong@cn.fujitsu.com>
* appliance: Make appliance building thread-safe (RHBZ#790721).Richard W.M. Jones2012-02-151-1/+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.
* NEW API: add a new api wipefsWanlong Gao2012-02-101-1/+1
| | | | | | | Add the new api wipefs to erase the filesystem signatures on a device but now erase any data. Signed-off-by: Wanlong Gao <gaowanlong@cn.fujitsu.com>
* docs: Note that JRuby should use the Java bindings.Richard W.M. Jones2012-02-091-0/+2

* 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.
