* Spin off hivex as a separate upstream project.Richard Jones2010-02-221-4/+4
| | | | | | | | | | | | | | This commit makes the semi-independent hivex library into a separate upstream project. The git repo for hivex is now: http://git.annexia.org/?p=hivex.git;a=summary Downloads of hivex are available here: http://libguestfs.org/download/ All questions, patches, bugs etc should be sent to the libguestfs mailing list and bug tracker.

* Remove references to FTP, replace with FUSE.Richard Jones2010-02-152-7/+9
| | | | | | | We originally intended to implement an FTP server (and before than, an NFS server). But we didn't implement either. We did however implement a FUSE service (guestmount) which takes the place of both.
* Remove some unused variables.Richard Jones2010-02-151-2/+1
| | | | | | Since we have to compile with -Wno-unused-variables, we don't spot unused variables in code. I found these by compiling the code in Ubuntu.
* daemon: Don't need to prefix error messages with the command name.Richard Jones2010-02-121-1/+1
| | | | | | | | | | | | | | | | | | | | The RPC stubs already prefix the command name to error messages. The daemon doesn't have to do this. As a (small) benefit this also makes the daemon slightly smaller. Code in the daemon such as: if (argv[0] == NULL) { reply_with_error ("passed an empty list"); return NULL; } now results in error messages like this: ><fs> command "" libguestfs: error: command: passed an empty list (whereas previously you would have seen ..command: command:..)
* generator: Don't prefix error messages with command name.Richard Jones2010-02-121-11/+10
| | | | | | | The command name is already being added by the RPC stubs, so adding it again in Perl and C# just results in doubled error messages like: foo: foo: the error
* New APIs: add-drive{,-ro}-with-if allows you to set QEMU block emulation.Richard Jones2010-02-122-5/+44
| | | | | | | | | | | The default if=... comes from configure time (currently it defaults to if=virtio). This change allows you to set the QEMU block emulation. We don't think this will be used very often, but virt-v2v requires it in order to work around a subtle problem with running 'mkinitrd' in an appliance attached to a guest.

* Use mount-options instead of mount to avoid implicit -o sync.Richard Jones2010-02-102-17/+26
| | | | | | | | | | | | | | | guestfs_mount adds -o sync implicitly. This causes a very large performance problem for write-intensive programs (eg. virt-v2v). Document this as a "gotcha". Change the tests, guestfish, Sys::Guestfs::Lib, guestmount to use mount-options instead. (Note that this gotcha does not affect mount-ro). The source of the performance problem was first identified by Matthew Booth.
* Add -enable-kvm option to qemu command line.Richard Jones2010-02-091-0/+31
| | | | | | | | If the version of qemu being used supports -enable-kvm option, then check if /dev/kvm is openable and add this option. I have found this option makes no difference, although it is *supposed* to enable KVM (hardware virtualization) support.

* supermin: Prevent multilib corruption (RHBZ#558593).Richard Jones2010-01-271-2/+4
| | | | | | | | | | | | | | | | | | | On some combination of installing, upgrading and removing the base libguestfs package on x86_64, multilib can corrupt libguestfs by leaving a copy of /usr/bin/libguestfs-supermin-helper around which references the wrong architecture (usually, contains links to the i386-based appliance, when the x86_64 appliance should be constructed). This commit changes libguestfs-supermin-helper so that the script is the same on all architectures. Instead, the library passes the differences to the script (eg. $host_cpu). Because the i386 and x86_64 libraries should be at different locations (/usr/lib vs /usr/lib64) this should prevent multilib from screwing things up.

* guestfish: Use xstrtol to parse integers (RHBZ#557655).Richard Jones2010-01-251-4/+50
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Current code uses atoi to parse the generator Int type and atoll to parse the generator Int64 type. The problem with the ato* functions is that they don't cope with errors very well, and they cannot parse numbers that begin with 0.. or 0x.. for octal and hexadecimal respectively. This replaces the atoi call with a call to Gnulib xstrtol and the atoll call with a call to Gnulib xstrtoll. The generated code looks like this for all Int arguments: { strtol_error xerr; long r; xerr = xstrtol (argv[0], NULL, 0, &r, ""); if (xerr != LONGINT_OK) { fprintf (stderr, _("%s: %s: invalid integer parameter (%s returned %d)\n"), cmd, "memsize", "xstrtol", xerr); return -1; } /* The Int type in the generator is a signed 31 bit int. */ if (r < (-(2LL<<30)) || r > ((2LL<<30)-1)) { fprintf (stderr, _("%s: %s: integer out of range\n"), cmd, "memsize"); return -1; } /* The check above should ensure this assignment does not overflow. */ memsize = r; } and like this for all Int64 arguments (note we don't need the range check for these): { strtol_error xerr; long long r; xerr = xstrtoll (argv[1], NULL, 0, &r, ""); if (xerr != LONGINT_OK) { fprintf (stderr, _("%s: %s: invalid integer parameter (%s returned %d)\n"), cmd, "size", "xstrtoll", xerr); return -1; } size = r; } Note this also fixes an unrelated bug in guestfish handling of RBufferOut. We were using 'fwrite' without checking the return value, and this could have caused silent failures, eg. in the case where there was not enough disk space to store the resulting file, or even if the program was interrupted (but continued) during the write. Replace this with Gnulib 'full-write', and check the return value and report errors.
* Add 'filesize' call.Richard Jones2010-01-252-1/+13
| | | | | Returns the size of a file. You can already do this with 'stat', but this call is good for scripting.

* qemu: Upstream regression of -stdio serial option.Richard Jones2010-01-071-4/+17
| | | | | | | | | | | | | Best explained by the comment in the code: /* Newer versions of qemu (from around 2009/12) changed the * behaviour of monitors so that an implicit '-monitor stdio' is * assumed if we are in -nographic mode and there is no other * -monitor option. Only a single stdio device is allowed, so * this broke the '-serial stdio' option. There is a new flag * called -nodefaults which gets rid of all this default crud, so * let's use that to avoid this and any future surprises. */

* Remove separate inspector_generator.ml, combine this with generator.ml.Richard Jones2009-12-311-2/+506
| | | | | | | | | | | This commit combines the previously separate "inspector_generator.ml" program which generated bindings for virt-inspector. Having two separate programs caused no end of troubles for developers, so we now combine them into a single program. NOTE: OCaml xml-light is now *required* in order to rebuild the generated code.

* lib: Add thread-safety to global list of handles.Richard Jones2009-12-071-9/+10
| | | | | | | | | | | | | | | | This commit uses the Gnulib 'lock' module to implement a mutex on the global list of handles which is stored by the library. Note that Gnulib nicely avoids explicitly linking with -lpthread unless the application program itself links to -lpthread.

* availability: Add a test for this call.Richard Jones2009-11-241-1/+1
| | | | | | Because all the tested groups are optional, there's not really a group we can reliably test, therefore test against the empty list (which should not fail).

* generator: Passing "" to StringList tests should turn into empty list.Richard Jones2009-11-241-0/+2
| | | | | | | | This is a bug in the generator which wasn't being tickled. If you had a test which expected a StringList or DeviceList parameter, and you passed "" to that test, then you'd (probably) expect to be testing an empty list, but in fact you got a single element list containing an empty string. This fixes it so you get an empty list.

* availability: Add optional groups and implement guestfs_available call.Richard Jones2009-11-201-62/+138
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The current groups are defined very conservatively using the following criteria: (a) Would be impossible to implement on Windows because of sheer architectural differences (eg: mknod). (b) Already optional (augeas, inotify). (c) Not currently optional but not implemented on older RHEL and Debian releases (ntfs-3g.probe, scrub, zerofree). The optional groups I've defined according to these criteria are: . augeas . inotify . linuxfsuuid . linuxmodules . linuxxattrs . lvm2 . mknod . ntfs3g . scrub . selinux . zerofree (Note that these choices don't prevent us from adding more optional groups in future. On the other hand to avoid breaking ABIs we would not wish to change the above groups). The rest of this large commit is really just implementation: Each optional function is classified using Optional "group" flag in the generator. The daemon has to implement a function int optgroup_<name>_available (void); for each optional group. Some of these functions are fixed at compile time, and some do simple run-time tests. The do_available implementation in the daemon looks up the correct function in a table and runs it. We document the optional groups in the guestfs(3) man page. Also: I added a NOT_AVAILABLE macro in order to unify all the existing places where we had a message equivalent to "function __func__ is not available".
* availability: Add guestfs_available.Richard Jones2009-11-202-2/+61
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Start a new API allowing groups of functions to be tested for availability. There are two reasons for this: (1) If libguestfs is built with missing dependencies (eg. no Augeas lib) then the corresponding functions are disabled in the appliance. Up till now there has been no way to test for this except to speculatively issue commands and check for errors. (2) When we port the daemon to Win32 it is likely that major pieces of functionality won't be available (eg. LVM support). This API gives a way to test for that. There is no change for existing clients: you still have to check for errors from individual API calls. For new clients, you will be able to test for availability of particular APIs. Usage scenario (A): An LVM editing tool which requires both the LVM API and inotify in order to function at all: char *apis[] = { "inotify", "lvm2", NULL }; r = guestfs_available (g, apis); if (r == -1) { /* print an error and exit */ } Usage scenario (B): A general purpose tool which optionally provides configuration file editing, but this can be disabled, the result merely being reduced functionality: char *apis[] = { "augeas", NULL }; r = guestfs_available (g, apis); enable_config_edit_menus = r == 0;

* generator: open Unix module by default.Richard Jones2009-11-191-22/+23
| | | | | | | | | | | | | | Add: open Unix at the top of the generator, which means that we don't need to prefix any 'Unix.foo' symbols (we can just use 'foo' instead). Unfortunately the Unix module shadows one symbol in Pervasives (the Pervasives module is opened by default in OCaml code). That symbol is 'stdout'. So we replace this with 'Pervasives.stdout' in two places. Still a net reduction in code size.
* syntax-check: Fix tab-vs-space issue in the generator.Richard Jones2009-11-191-4/+4

* build: Fix inter-directory dependenciesMatthew Booth2009-11-191-16/+19
| | | | | | | | | | | | | | | | | | | | | | | | | | | This change adds an explicit dependency on generator.ml for every file it generates, except java files. Java is left for another time because it's considerably trickier. It also adds a build rule for src/libguestfs.la so it can be rebuilt as required from other directories. It does this by creating a top level make file, subdir-rules.mk, which can be included from sub-directories. sub-directories need to define 'generator_built' to include local files which are built by generator.ml, and they will be updated automatically. This fixes parallel make, and will automatically re-create generated files when make is run from any directory. It also fixes the problem which efad4f53 was targetting. Specifically, src/guestfs_protocol.(c|h) had an erroneous dependency on stamp-generator, and therefore generator.ml, despite not being directly created by it. This caused them to be recreated every time generator.ml ran rather than only when src/guestfs_protocol.x was updated, which cascaded into a daemon and therefore appliance update. This patch also changes the contents of the distribution tarball by including files created by rpcgen.
* generator: Acquire lock to prevent two parallel runs of the generator.Richard Jones2009-11-191-6/+27
| | | | | | | | | | | | | This commit acquires a lock on a file to prevent two parallel runs of the generator from stomping on each other. The second run will wait for the first to complete before starting. The lock is acquired on the "HACKING" file because it's convenient -- we are already checking this file exists to make sure that we don't start off in the wrong directory. Tested by adding some artificial sleeps in the code to observe locking behaviour between two parallel runs.
