1 Only the most important changes more recent than version 0.6 are noted here.
4 Added support for "pipable" WIMs. This support allows capturing images
5 to standard output or applying images from standard input, but they are
6 not compatible with Microsoft's software and are not created by default.
7 See documentation for --pipable flag of `wimlib-imagex capture' for more
8 information. Two new functions have been added to the library to fully
9 support this: wimlib_write_to_fd() and wimlib_extract_image_from_pipe().
11 wimlib now preserve WIM integrity tables by default, even if
12 WIMLIB_WRITE_FLAG_CHECK_INTEGRITY is not specified. This changes the
13 behavior of `wimlib-imagex' whenever the WIM being operated on contains
14 an integrity table and the '--check' option is not specified.
16 `wimlib-imagex capture' now creates LZX-compressed WIMs by default
17 (when --compress is not specified). This provides the best compression
18 ratio by default, which is usually what is desired, at a cost of some
21 For convenience, `wimlib-imagex' now supports being invoked as
22 wimCOMMAND, where COMMAND is the command as in `wimlib-imagex COMMAND';
23 for example, it can be invoked as `wimapply' as an alternative to
24 `wimlib-imagex apply'. The appropriate hard links are created in UNIX
25 installations of `wimlib-imagex', while for the Windows distribution of
26 `wimlib-imagex', batch files that emulate this behavior are generated.
28 `wimlib-imagex' no longer recognizes the 'mount', 'mountrw', and
29 'unmount' commands on Windows, since they didn't work on Windows anyway.
31 Security descriptors are now extracted correctly on Windows.
33 `mkwinpeimg' now supports grabbing files from the WAIK supplement rather
36 The test suite no longer fails when run in a locale where the decimal
37 separator is not a period.
39 WIMLIB_PROGRESS_MSG_EXTRACT_DENTRY has been removed and
40 WIMLIB_EXTRACT_FLAG_VERBOSE re-reserved for future use.
42 The extraction code has been rewritten and it will now be easier to
43 support new features on all supported backends (currently Win32, UNIX,
44 and NTFS-3g). For example, hard-linked extraction mode (--hardlink) is
45 now supported on all backends, not just UNIX.
47 A few changes were made to the error codes returned by library routines.
49 This update bumps the shared library version number up to 9, since it
50 doesn't quite not maintain binary compatibility with previous releases.
53 Fixed bug in `wimlib-imagex export' that made it impossible to export an
54 image from a WIM that is readonly at the filesystem level.
56 Return error code rather than segfaulting when trying to list files from
57 a non-first part of a split WIM.
59 Joining a WIM will now preserve the RP_FIX and READONLY flags.
62 On Windows, paths given to wimlib-imagex are now treated case
65 Improved behavior regarding invalid filenames; in particular, on
66 Windows, wimlib-imagex will, when extracting, now omit (with an option
67 to override this default) filenames differing only in case, or filenames
68 containing characters not valid on Windows.
70 On Windows, wimlib now supports capturing and extracting long paths
71 (longer than the so-called MAX_PATH).
73 On Windows, `wimlib-imagex update' now acquires proper privileges when
74 running as an Administrator.
76 `wimlib-imagex update' will now complain if no image is specified when
77 trying to update a multi-image WIM.
79 `wimlib-imagex update' now supports specifying a single update command
80 directly on the command line using the --command option.
82 wimlib-imagex will now choose different units for progress messages,
83 depending on the amount of data that needs to be processed.
85 `wimlib-imagex append' will now generate a unique WIM image name if no
86 name is specified and the defaulted name already exists in the WIM.
88 wimlib now allows you to create unnamed WIM images, which can then only
89 be referred to by index.
91 wimlib now allows you to explicitly declare you want write access to a
92 WIM by providing the WIMLIB_OPEN_FLAG_WRITE_ACCESS flag to
95 wimlib now respects the WIM_HDR_FLAG_READONLY flag when set in the WIM
98 Progress callbacks have been added to wimlib's wimlib_update_image()
101 Added wimlib_get_wim_info(), wimlib_set_wim_info(),
102 wimlib_iterate_dir_tree(), and wimlib_iterate_lookup_table() functions
105 NTFS-3g capture now only warns about two conditions previously treated
108 Fixed a couple issues with using wimlib-imagex on UDF filesystems on
111 wimlib now correctly detects and returns an error when reading a WIM
112 image with a cyclic directory structure. (Fun fact: such a WIM will
113 crash Microsoft's software.)
116 Added new "extract" and "update" subcommands to wimlib-imagex, along
117 with associated APIs in the library. These commands are intended mainly
118 for Windows use but can be used on UNIX as well.
120 Many documentation improvements.
122 Fixed a bug in the Windows build where relative symbolic links were not
123 captured in reparse-point fixup mode.
125 Fixed a bug in the Windows build where file handles were left open to
126 the WIM file, causing `wimlib_imagex optimize' to fail in some cases.
128 Fixed a bug in the Windows build of wimlib-imagex where globbing
129 split-WIM parts could cause the program to crash.
131 Fixed a bug where the creation time of WIM images would be shown instead
132 of the last modification time.
134 With the Windows build it is now possible to restore a WIM containing
135 symbolic links as a non-Administrator; however you will receive warnings
136 about not being able to extract the symbolic links.
139 Capturing a WIM image should now be significantly faster in most cases
140 due to improved use of the operating system's cache and avoiding reading
141 files twice whenever possible.
143 The Windows build should now work on Windows XP.
145 The Windows build now supports capturing and restoring hidden,
146 compressed, sparse, and encrypted files.
148 The Windows build now supports capturing and applying WIM images from
149 filesystems other than NTFS (with some reduced functionality).
151 The Windows build now extracts short names correctly.
153 Added support for "reparse-point" fixups (i.e. fixing up of symbolic
154 links). See docs for --rpfix and --norpfix flags of `wimlib-imagex
155 capture' and `wimlib-imagex apply'.
157 The performance of splitting and joining WIMs should be slightly
160 The LZX and XPRESS compression and decompression functions are now
161 exported from the library.
164 Improvements and bugfixes for the Windows build.
166 Added --strict-acls options.
168 Fixed the way that wimlib determines the order of images in the WIM.
171 Since wimlib can now be used on Windows, wimlib's implementation of
172 ImageX has been renamed to wimlib-imagex to avoid confusion with
173 Microsoft's implementation of ImageX, which would have the same file
174 name ("imagex.exe"). If you really don't like this you can pass the
175 --with-imagex-progname option to `configure' to choose a different name,
176 or even simply rename the binary yourself (but the former way will
177 configure the man pages to use the chosen name).
179 Various bugs fixed in the Windows build. Mainly to do with capturing
180 and restoring alternate data streams correctly in weird cases, and
181 requesting the correct privileges when opening files. Also added the
182 --noacls options to wimlib-imagex capture, append, and apply.
184 Windows build again: FindFirstStreamW() and FindNextStreamW() are now
185 dynamically loaded, so this may make the library compatible with Windows
186 XP (however, there may still be other problems).
189 Added experimental support for native Windows builds. Binaries can be
190 downloaded from the SourceForge page.
192 --source-list option added to `imagex capture' and `imagex append'.
194 Better support for different character encodings.
197 Storing UNIX file owners, groups, and modes in WIM images is now
198 possible using `imagex capture' with the --unix-data flag.
200 Minor bug fixes and documentation fixes.
203 NTFS capture: Fixed capturing duplicate reparse points.
205 NTFS capture: Capture first unnamed stream if there are more than one
206 (print warning instead of error).
208 Allow multiple test cases to execute concurrently (e.g. make -j2 check).
211 Added --arch switch to mkwinpeimg script to support getting AMD64 WinPE
214 Update to work with ntfs-3g version 2013.1.13.
217 Fixed truncating file to shorter but non-zero length on read-write
220 Various code cleanups and minor documentation fixes.
223 LZX and XPRESS decompression have received some additional optimizations
224 and should now be even faster. (Although, they were already pretty
225 fast--- much faster than typical I/O speeds.)
227 Fixed a bug introduced in v1.2.1 that would cause a directory tree
228 containing hard links to be captured incorrectly in some cases.
231 By default, unmounting a read-write mounted WIM with 'imagex unmount
232 --commit' will now change the WIM in-place without needing to write the
233 entire WIM again. Use 'imagex unmount --commit --rebuild' to get the
236 'imagex unmount' no longer has a hard-coded limit of 10 minutes to wait
237 for a response from the daemon servicing the mounted WIM. Instead,
238 every second 'imagex unmount' will check if the daemon is still alive,
239 and keep waiting if so, otherwise terminate with an error.
241 'imagex unmount --commit' on a read-write mounted WIM will now print
242 progress information regarding the writing of new or modified streams
243 the WIM, just like when capturing or appending a WIM.
245 A small change has been made to XPRESS compression and it should improve
246 the compression ratio slightly.
248 A change was made that may improve performance slightly when applying a
249 WIM image to a NTFS volume.
251 Microsoft has managed to introduce even more bugs into their software,
252 and now the WIMs for Windows 8 have incorrect (too low) reference counts
253 for some streams. This is unsafe because such streams can be removed
254 when they are in actuality still referenced in the WIM (perhaps by a
255 different image). wimlib will now work around this problem by fixing
256 the stream reference counts. This is only done when wimlib_delete_image() is
257 called ('imagex delete') or when wimlib_mount_image() is called with
258 WIMLIB_MOUNT_FLAG_READWRITE ('imagex mountrw'). Please note that this
259 requires reading the metadata for all images in the WIM, so this will
260 make these operations noticably slower on WIMs with multiple images.
262 Various other bugfixes.
265 Appending images to a WIM is now be done by default without re-building
266 the whole WIM. Use the --rebuild flag to get the old behavior (which
267 was to re-build the entire WIM when a new image is appended).
269 A new command `imagex optimize' is now available to manually re-build a
270 WIM that has wasted space due to repeated appends.
272 Progress information has been improved, and now arbitrary callback
273 functions can be used to show the progress of a WIM operation.
275 A possible bug with changing the bootable image of a WIM was fixed.
277 Some advisory locking is now done to prevent two processes from
278 modifying a WIM at the same time (but only in some cases). For example,
279 you cannot mount two images from a WIM read-write at the same time.
281 Some functions have been reorganized:
282 * wimlib_mount() renamed to wimlib_mount_image().
283 * wimlib_unmount() renamed to wimlib_unmount_image().
284 * wimlib_overwrite_xml_and_header() removed as
285 wimlib_overwrite() suffices now.
286 * wimlib_apply_image_to_ntfs_volume() removed as
287 wimlib_extract_image() suffices now.
288 * wimlib_add_image_from_ntfs_volume() removed as
289 * wimlib_add_image() suffices now.
291 Previously, the soname of libwim.so has been 0.0.0, despite many
292 interface changes. The soname is now updated to 1.0.0 and will now be
293 updated each release.
296 Resources will now be compressed using multiple threads by default.
297 (This applies to `imagex capture', `imagex append', and `imagex
300 Some performance improvements in mounted WIMs.
302 More progress information is shown when capturing a WIM.
305 Lots of minor fixes, code cleanups, and some documentation updates.
306 Nothing in particular is really noteworthy.
309 LZX and XPRESS compression improvements.
311 Fixed calculation of Directory Count, File Count, Total Bytes, and Hard
312 Link Bytes of the WIM.
315 Fixed bug when capturing NTFS file with multiple named data streams.
317 Internally, we are now using inode structures, even though these don't
318 appear literally in the WIM file. This simplifies some of the code
319 (mainly for WIM mounting) and likely fixed a few problems, although it
323 Fixed problem when exporting images from XPRESS to LZX compressed WIM or
327 Enough changes to call it version 1.0.0!
329 Capturing a WIM directly from a NTFS volume, and applying a WIM directly
330 to a NTFS volume, is now supported.
332 Hard links and symbolic links have much improved support. They are
333 supported for WIM capture, WIM application, and mounted WIMs (you can
334 even make them on read-write mounted WIMs).
336 Alternate data streams are now supported on mounted WIMs through an
337 xattr or a Windows-style stream interface. Also they are supported when
338 capturing a WIM from NTFS or applying a WIM to NTFS.
340 Split WIMs are better supported. You may now apply an image directly
341 from a split WIM, mount an image from a split WIM read-only, or export
342 an image from a split WIM.
344 Using a capture configuration file is now supported (but not fully yet).
346 SHA1 message digests are checked in more places, so we can make sure
347 applied and captured data is correct.
349 Man pages have been updated and consolidated.
352 Fixed segfault when unmounting read-only WIM.
355 Support for joining and splitting WIMs.
356 Also, security data is now preserved by default.
359 Can now build with older gcc and system headers, like on CentOS 5.
362 Fixed bug that made it impossible to overwrite files in read-write
366 Write byte-order mark before WIM XML data. (imagex.exe requires this to
