* New API: guestfs_copy_size to copy a fixed number of bytes.Richard Jones2010-03-231-0/+81
| | | | | | | This is similar to 'guestfs_dd', but it copies just a fixed number of bytes from the source to the destination. It's an error if the source is too short or if the destination is too small.
* New APIs: Query the relationship between LVM objects.Richard Jones2010-03-181-0/+83
| | | | | | | | | These calls allow you to query the relationship between LVM objects, for example, which PVs contain a VG, or which LVs are contained in a VG. See the example / test program 'regressions/test-lvm-mapping.pl' for an example of how to do this from Perl.
* daemon: Add a trim utility function.Richard Jones2010-03-182-0/+24
| | | | | This function trims the whitespace from around a string. It does this in-place, so it can be called for malloc'd strings.
* Tab to space (whitespace fixes only).Richard Jones2010-03-121-1/+1
|
* Distribute .gitignore files.Richard Jones2010-02-151-1/+2
| | | | | These are useful for Debian since they keep the tarball unpacked in git.
* daemon: Don't need to prefix error messages with the command name.Richard Jones2010-02-1241-113/+116
| | | | | | | | | | | | | | | | | | | | 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:..)
* New API call: initrd-cat to list a file from an initrd.Richard Jones2010-02-091-0/+121
|
* Implement 'vgrename' and 'lvrename' APIs.Richard Jones2010-01-281-0/+44
|
* Add 'filesize' call.Richard Jones2010-01-251-0/+18
| | | | | Returns the size of a file. You can already do this with 'stat', but this call is good for scripting.
* Update to latest Gnulib.Richard Jones2010-01-132-2/+7
|
* daemon: Work around udevsettle issue (RHBZ#548121).Richard Jones2009-12-181-21/+9
|
* daemon error handling: Define a new function reply_with_perror_errno.Richard Jones2009-12-072-5/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | This allows you to save the errno from a previous call and pass it to reply_with_perror. For example, original code: r = some_system_call (); err = errno; do_cleanup (); errno = err; if (r == -1) { reply_with_perror ("failed"); return -1; } can in future be changed to: r = some_system_call (); err = errno; do_cleanup (); if (r == -1) { reply_with_perror_errno (err, "failed"); return -1; }
* daemon error handling: recursive_mkdir shouldn't need to set errno.Richard Jones2009-12-071-5/+11
|
* daemon error handling: Clear errno before calling stub functions.Richard Jones2009-12-041-1/+16
| | | | | | This just ensures that we accurately report errors, even if our error path code doesn't set errno. We won't end up with a bogus errno left over from a previous call.
* Whitespace change.Richard Jones2009-11-271-1/+1

* daemon/Win32: provide htonl, htons, ntohl, ntohs functions.Richard Jones2009-11-265-1/+90
| | | | These functions are not available on Windows.

|
* daemon: Link guestfs_protocol.[ch] into the daemon directory.Richard Jones2009-11-261-5/+24
| | | | | | | | | | | Instead of doing a recursive call into the src/ directory to build the object files, hard link the source files into the daemon directory and build them separately. See: http://www.redhat.com/archives/libguestfs/2009-November/msg00254.html Thanks to Jim Meyering for noticing a typo in the original version.

|
* daemon/Win32: Use xdr_u_int for PortableXDR compatibility.Richard Jones2009-11-252-8/+8
| | | | PortableXDR didn't support xdr_uint32_t. xdr_u_int is the same type.
* daemon/Win32: Don't bother blocking SIGPIPE on Win32.Richard Jones2009-11-251-0/+2
|
* daemon/Win32: Use gnulib getaddrinfo module.Richard Jones2009-11-253-1/+12
|
* daemon/Win32: Implement statvfs using GetDiskFreeSpaceEx.Richard Jones2009-11-254-2/+128
| | | | | | | At the time of writing Gnulib didn't support Win32 for its fsusage API. Therefore this patch uses GetDiskFreeSpaceEx if it's available (on Windows) otherwise falls back to using Gnulib fsusage.
* daemon: Move statvfs code into separate file.Richard Jones2009-11-253-38/+69
| | | | | | This makes no functional change to the code. It just moves the statvfs-related code out of daemon/stat.c into a new file called daemon/statvfs.c.
* daemon: Use gnulib futimens module.Richard Jones2009-11-255-11/+10
| | | | | | | | | Instead of checking for futimens support and falling back (incorrectly in one case) to using futimes, use gnulib's module. However the gnulib module does not yet support Win32, so this change is only really useful on platforms like RHEL 5.
* daemon/Win32: Use gnulib pread module.Richard Jones2009-11-252-0/+3
|
* sync: Windows implementation of sync() call.Richard Jones2009-11-254-7/+110
| | | | | Replace calls to sync() with calls to sync_disks() which supports Win32 via FlushFileBuffers.
* daemon: Alternate implementation of posix_fallocate.Richard Jones2009-11-252-1/+23
| | | | | If the posix_fallocate function is not available [ie. Windows] use an alternate implementation that just loops and writes.
* dd: Missing include of <string.h>Richard Jones2009-11-251-0/+1
| | | | Breaks compilation on Windows.

* availability: Add optional groups and implement guestfs_available call.Richard Jones2009-11-2015-80/+214
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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".
