* 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.

* 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".
* availability: Add guestfs_available.Richard Jones2009-11-202-0/+39
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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;
* daemon/Win32: Use gnulib modules for first porting to Win32.Richard Jones2009-11-206-14/+44

* maint: use EXIT_SUCCESS and EXIT_FAILURE, not 0 and 1 to exitJim Meyering2009-11-202-28/+28
| | | | | | | | | | | | | | | Convert all uses automatically, via these two commands: git grep -l '\<exit *(1)' \ | grep -vEf .x-sc_prohibit_magic_number_exit \ | xargs --no-run-if-empty \ perl -pi -e 's/\b(exit ?)\(1\)/$1(EXIT_FAILURE)/' git grep -l '\<exit *(0)' \ | grep -vEf .x-sc_prohibit_magic_number_exit \ | xargs --no-run-if-empty \ perl -pi -e 's/\b(exit ?)\(0\)/$1(EXIT_SUCCESS)/' * .x-sc_prohibit_magic_number_exit: New file. Edit (RWMJ): Don't change Java code.
* maint: remove unnecessary include of openat.hJim Meyering2009-11-201-2/+0
| | | | * daemon/realpath.c: Don't include "openat.h". not used.
* build: update gnulib submodule to latestRichard Jones2009-11-201-0/+17
|
* daemon/gnulib: Include glob module.Richard Jones2009-11-202-1/+18
|
* daemon/Win32: Don't include missing headers.Richard Jones2009-11-201-3/+15
| | | | | This is a partial fix for code in guestfsd.c where many of these header files are missing on Win32.
* daemon/Win32: make some functions and fields optional.Richard Jones2009-11-205-4/+98
| | | | | | | | | | | | inotify: Make this optional on platforms that don't have this interface. mknod, mkfifo etc.: Make these optional on non-Unix platforms. readdir: If d_type field is missing on the platform, set the corresponding field to 'u'. stat: st_blocks and st_blksize are missing on non-Unix platforms, so set these fields to -1 in the corresponding structures.
* daemon/Win32: NAME_MAX does not exist on Windows, use FILENAME_MAX instead.Richard Jones2009-11-201-0/+5
|
* daemon: Missing #includes revealed by cross-compiling.Richard Jones2009-11-204-0/+4
|
* daemon/Win32: Ignore mingw32-config.cache.Richard Jones2009-11-201-0/+1
| | | | | The Fedora Windows cross-compiler 'mingw32-configure' script always uses a configure cache. Ignore that file.
* build: Fix inter-directory dependenciesMatthew Booth2009-11-191-5/+21
| | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
* daemon/RHEL: Choose correct udev settle script.Richard Jones2009-11-181-1/+21
| | | | | | | | | On RHEL/CentOS 5.4, udevadm settle command does not work. This didn't affect us before, but now that we're using parted for partitioning, we *do* need to wait for udev to settle (because parted isn't waiting for this, unlike sfdisk). This commit chooses the correct program to run.

* Generic partition creation interface.Richard Jones2009-11-102-0/+358
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This commit introduces a generic partition creation interface which should be future-proof and extensible, and partially replaces the old sfdisk-based interface. The implementation is based on parted but is hopefully not too dependent on the particulars of parted. The following new calls are introduced: guestfs_part_init: Initialize a disk with a partition table. Unlike the sfdisk- based interface, we also support GPT and other partition types, which is essential to scale to devices larger than 2TB. guestfs_part_add: Add a partition to an existing disk. guestfs_part_disk: Convenience function which combines part_init & part_add, creating a single partition that covers the whole disk. guestfs_part_set_bootable: guestfs_part_set_name: Set various aspects of existing partitions. guestfs_part_list: List partitions on a device. This returns a programming-friendly list of partition structs (in contrast to sfdisk-l which cannot be parsed). guestfs_part_get_parttype: Return the partition table type, eg. "msdos" or "gpt". The following calls are planned, but not added currently: guestfs_part_get_bootable guestfs_part_get_name guestfs_part_set_type guestfs_part_get_type
* Fix compilation when Augeas is not present.Richard Jones2009-11-101-1/+1

* appliance: Enhance mkfs to support many more filesystem types.Richard Jones2009-11-091-17/+62
| | | | | | | | | | | | | | | | This fixes support for NTFS, and adds support for: - reiserfs - btrfs - GFS and GFS2 - JFS - HFS and HFS+ - NILFS - OCFS2 (disabled) We don't enable OCFS2 by default, because it pulls in about 140 extra packages into the appliance. GFS & GFS2 default to single node (no lock manager etc).
* Fix prototype of commandv to match prototype of commandrv.Richard Jones2009-11-095-7/+8

* daemon: Always reflect command stderr to stderr when debugging.Richard W.M. Jones2009-11-091-9/+16
| | | | | | | | | | When debugging (ie. LIBGUESTFS_DEBUG=1 & verbose flag set in daemon) always reflect any stderr output from commands that we run to stderr of the daemon, so it is visible. Previously if stderror == NULL in command*, stderr output was just eaten and discarded which meant useful error messages could be lost.
* daemon: Add flags argument to command*() functions.Richard W.M. Jones2009-11-092-18/+51
| | | | | | | | | | | | | | | | This adds new variations of the command*() functions which take a 'flags' argument. Currently the only flag available is defined as follows: COMMAND_FLAG_FOLD_STDOUT_ON_STDERR: For broken external commands that send error messages to stdout (hello, parted) but that don't have any useful stdout information, use this flag to capture the error messages in the *stderror buffer. If using this flag, you should pass stdoutput as NULL because nothing could ever be captured in that buffer. This patch also adds some documentation for command*() function.
* daemon: Build daemon with AC_SYS_LARGEFILE.Richard Jones2009-11-041-0/+3
|
* daemon: When running external commands, open stdin as /dev/nullRichard Jones2009-11-041-0/+1
| | | | | | | | Previously when we ran external commands from the daemon, stdin (ie. fd 0) was closed. This caused a problem when running the external hexdump command which seems to break if stdin is closed. This patch opens stdin on /dev/null.
* New API call: preadRichard Jones2009-11-021-0/+52
| | | | | guestfs_pread lets you do partial file reads from arbitrary places within a file. It works like the pread(2) system call.
* New API calls: lstatlist, lxattrlist, readlinklist.Richard Jones2009-11-023-0/+324
| | | | | | | | These three functions are very specifically designed for FUSE support, so we can list directories efficiently. Instead of making lots of lstat, lgetxattr and readlink calls, we can make just three calls per directory to grab all the attributes (which we then cache briefly).
* New API calls: truncate, truncate_size, mkdir_mode, utimens, lchown.Richard Jones2009-11-025-0/+182
| | | | | | | | | | | | | | | truncate, truncate_size: Used to truncate files to a particular size, or to zero bytes. mkdir_mode: Like mkdir but allows you to also specify the initial permissions for the new directory. utimens: Set timestamp on a file with nanosecond accuracy. lchown: Corresponding to lchown(2) syscall (we already have chown). The implementation is complicated by the fact that we had to add an Int64 parameter type to the generator.
* daemon: Don't warn on -Wunsafe-loop-optimizations.Richard Jones2009-11-021-0/+2
| | | | | Ignore -Wunsafe-loop-optimizations, same as in the top level configure file.
* New API: vfs_type - get the Linux VFS driver for a mounted device.Richard Jones2009-10-262-0/+54
|
* daemon: Change chdir to use openat/fdopendir.Richard Jones2009-10-263-9/+67
| | | | Uses Gnulib implementation of openat which should be portable.
* New API: case-sensitive-path to return case sensitive path on NTFS 3g fsRichard Jones2009-10-261-0/+122
| | | | | | | | | | | | | | | | | | | | This function handles an annoyance/peculiarity of the Linux NTFS 3g driver, which is that it exports NTFS filesystems with names case sensitive, even though under Windows they would be case insensitive. This causes problems because the location of (eg.) c:\windows might appear as /windows or /WINDOWS (etc) depending on the inconsequential details of how it was originally created. Example of this problem on a real Windows guest: ><fs> file /windows/system32/config/system.log libguestfs: error: file: access: /windows/system32/config/system.log: No such file or directory ><fs> case-sensitive-path /windows/system32/config/system.log /WINDOWS/system32/config/system.LOG ><fs> file /WINDOWS/system32/config/system.LOG MS Windows registry file, NT/2000 or above
* Tab to space fixes, now passes 'make syntax-check'Richard Jones2009-10-201-5/+4
|
* guestfs_find: Fix memory leak of sysrootdir.Richard Jones2009-10-201-0/+1
|
* New API: find0 (unlimited version of find)Richard Jones2009-10-201-0/+99
| | | | | | | | | | | | | This adds a new API call guestfs_find0, which is like guestfs_find but mainly doesn't suffer from the protocol limit of the earlier command. The earlier command is not deprecated because it is still very useful. guestfs_find0 uses a FileOut parameter and writes the results to an external file. The filenames in the output are separated by ASCII NUL characters (so a bit like "find -print0"). There is also the addition of a regression test for this command.
* avoid use of all ctype macrosJim Meyering2009-09-245-12/+13
| | | | | | | | | | | | | | | | | | | | * cfg.mk (disable_temporarily): Don't disable sc_avoid_ctype_macros. * fish/tilde.c: Remove unnecessary inclusion of ctype.h. * bootstrap: Add gnulib's c-ctype module to the list. * daemon/m4/gnulib-cache.m4: Likewise. * daemon/ext2.c: Include "c-ctype.h", not <ctype.h>. Use c_isspace, etc, rather than isspace. * daemon/guestfsd.c: Likewise. * daemon/lvm.c: Likewise. * daemon/proto.c: Likewise. * fish/fish.c: Likewise. * fish/tilde.c: Likewise. * src/generator.ml: Likewise. * src/guestfs.c: Likewise. * examples/to-xml.c: Likewise. * examples/Makefile.am (to_xml_CPPFLAGS): Add -I$(top_srcdir)/gnulib/lib so inclusion of "c-ctype.h" works. (to_xml_CPPFLAGS): Rename from to_xml_CFLAGS.
