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 To make wimlib easier to use on Windows, wimlib_global_init() now
50 automatically attempts to acquire additional privileges on Windows, so
51 library clients need not do this (although they can provide a flag to
52 get the old behavior and manage privileges themselves).
54 This update bumps the shared library version number up to 9, since it
55 doesn't quite maintain binary compatibility with previous releases.
58 Fixed bug in `wimlib-imagex export' that made it impossible to export an
59 image from a WIM that is readonly at the filesystem level.
61 Return error code rather than segfaulting when trying to list files from
62 a non-first part of a split WIM.
64 Joining a WIM will now preserve the RP_FIX and READONLY flags.
67 On Windows, paths given to wimlib-imagex are now treated case
70 Improved behavior regarding invalid filenames; in particular, on
71 Windows, wimlib-imagex will, when extracting, now omit (with an option
72 to override this default) filenames differing only in case, or filenames
73 containing characters not valid on Windows.
75 On Windows, wimlib now supports capturing and extracting long paths
76 (longer than the so-called MAX_PATH).
78 On Windows, `wimlib-imagex update' now acquires proper privileges when
79 running as an Administrator.
81 `wimlib-imagex update' will now complain if no image is specified when
82 trying to update a multi-image WIM.
84 `wimlib-imagex update' now supports specifying a single update command
85 directly on the command line using the --command option.
87 wimlib-imagex will now choose different units for progress messages,
88 depending on the amount of data that needs to be processed.
90 `wimlib-imagex append' will now generate a unique WIM image name if no
91 name is specified and the defaulted name already exists in the WIM.
93 wimlib now allows you to create unnamed WIM images, which can then only
94 be referred to by index.
96 wimlib now allows you to explicitly declare you want write access to a
97 WIM by providing the WIMLIB_OPEN_FLAG_WRITE_ACCESS flag to
100 wimlib now respects the WIM_HDR_FLAG_READONLY flag when set in the WIM
103 Progress callbacks have been added to wimlib's wimlib_update_image()
106 Added wimlib_get_wim_info(), wimlib_set_wim_info(),
107 wimlib_iterate_dir_tree(), and wimlib_iterate_lookup_table() functions
110 NTFS-3g capture now only warns about two conditions previously treated
113 Fixed a couple issues with using wimlib-imagex on UDF filesystems on
116 wimlib now correctly detects and returns an error when reading a WIM
117 image with a cyclic directory structure. (Fun fact: such a WIM will
118 crash Microsoft's software.)
121 Added new "extract" and "update" subcommands to wimlib-imagex, along
122 with associated APIs in the library. These commands are intended mainly
123 for Windows use but can be used on UNIX as well.
125 Many documentation improvements.
127 Fixed a bug in the Windows build where relative symbolic links were not
128 captured in reparse-point fixup mode.
130 Fixed a bug in the Windows build where file handles were left open to
131 the WIM file, causing `wimlib_imagex optimize' to fail in some cases.
133 Fixed a bug in the Windows build of wimlib-imagex where globbing
134 split-WIM parts could cause the program to crash.
136 Fixed a bug where the creation time of WIM images would be shown instead
137 of the last modification time.
139 With the Windows build it is now possible to restore a WIM containing
140 symbolic links as a non-Administrator; however you will receive warnings
141 about not being able to extract the symbolic links.
144 Capturing a WIM image should now be significantly faster in most cases
145 due to improved use of the operating system's cache and avoiding reading
146 files twice whenever possible.
148 The Windows build should now work on Windows XP.
150 The Windows build now supports capturing and restoring hidden,
151 compressed, sparse, and encrypted files.
153 The Windows build now supports capturing and applying WIM images from
154 filesystems other than NTFS (with some reduced functionality).
156 The Windows build now extracts short names correctly.
158 Added support for "reparse-point" fixups (i.e. fixing up of symbolic
159 links). See docs for --rpfix and --norpfix flags of `wimlib-imagex
160 capture' and `wimlib-imagex apply'.
162 The performance of splitting and joining WIMs should be slightly
165 The LZX and XPRESS compression and decompression functions are now
166 exported from the library.
169 Improvements and bugfixes for the Windows build.
171 Added --strict-acls options.
173 Fixed the way that wimlib determines the order of images in the WIM.
176 Since wimlib can now be used on Windows, wimlib's implementation of
177 ImageX has been renamed to wimlib-imagex to avoid confusion with
178 Microsoft's implementation of ImageX, which would have the same file
179 name ("imagex.exe"). If you really don't like this you can pass the
180 --with-imagex-progname option to `configure' to choose a different name,
181 or even simply rename the binary yourself (but the former way will
182 configure the man pages to use the chosen name).
184 Various bugs fixed in the Windows build. Mainly to do with capturing
185 and restoring alternate data streams correctly in weird cases, and
186 requesting the correct privileges when opening files. Also added the
187 --noacls options to wimlib-imagex capture, append, and apply.
189 Windows build again: FindFirstStreamW() and FindNextStreamW() are now
190 dynamically loaded, so this may make the library compatible with Windows
191 XP (however, there may still be other problems).
194 Added experimental support for native Windows builds. Binaries can be
195 downloaded from the SourceForge page.
197 --source-list option added to `imagex capture' and `imagex append'.
199 Better support for different character encodings.
202 Storing UNIX file owners, groups, and modes in WIM images is now
203 possible using `imagex capture' with the --unix-data flag.
205 Minor bug fixes and documentation fixes.
208 NTFS capture: Fixed capturing duplicate reparse points.
210 NTFS capture: Capture first unnamed stream if there are more than one
211 (print warning instead of error).
213 Allow multiple test cases to execute concurrently (e.g. make -j2 check).
216 Added --arch switch to mkwinpeimg script to support getting AMD64 WinPE
219 Update to work with ntfs-3g version 2013.1.13.
222 Fixed truncating file to shorter but non-zero length on read-write
225 Various code cleanups and minor documentation fixes.
228 LZX and XPRESS decompression have received some additional optimizations
229 and should now be even faster. (Although, they were already pretty
230 fast--- much faster than typical I/O speeds.)
232 Fixed a bug introduced in v1.2.1 that would cause a directory tree
233 containing hard links to be captured incorrectly in some cases.
236 By default, unmounting a read-write mounted WIM with 'imagex unmount
237 --commit' will now change the WIM in-place without needing to write the
238 entire WIM again. Use 'imagex unmount --commit --rebuild' to get the
241 'imagex unmount' no longer has a hard-coded limit of 10 minutes to wait
242 for a response from the daemon servicing the mounted WIM. Instead,
243 every second 'imagex unmount' will check if the daemon is still alive,
244 and keep waiting if so, otherwise terminate with an error.
246 'imagex unmount --commit' on a read-write mounted WIM will now print
247 progress information regarding the writing of new or modified streams
248 the WIM, just like when capturing or appending a WIM.
250 A small change has been made to XPRESS compression and it should improve
251 the compression ratio slightly.
253 A change was made that may improve performance slightly when applying a
254 WIM image to a NTFS volume.
256 Microsoft has managed to introduce even more bugs into their software,
257 and now the WIMs for Windows 8 have incorrect (too low) reference counts
258 for some streams. This is unsafe because such streams can be removed
259 when they are in actuality still referenced in the WIM (perhaps by a
260 different image). wimlib will now work around this problem by fixing
261 the stream reference counts. This is only done when wimlib_delete_image() is
262 called ('imagex delete') or when wimlib_mount_image() is called with
263 WIMLIB_MOUNT_FLAG_READWRITE ('imagex mountrw'). Please note that this
264 requires reading the metadata for all images in the WIM, so this will
265 make these operations noticably slower on WIMs with multiple images.
267 Various other bugfixes.
270 Appending images to a WIM is now be done by default without re-building
271 the whole WIM. Use the --rebuild flag to get the old behavior (which
272 was to re-build the entire WIM when a new image is appended).
274 A new command `imagex optimize' is now available to manually re-build a
275 WIM that has wasted space due to repeated appends.
277 Progress information has been improved, and now arbitrary callback
278 functions can be used to show the progress of a WIM operation.
280 A possible bug with changing the bootable image of a WIM was fixed.
282 Some advisory locking is now done to prevent two processes from
283 modifying a WIM at the same time (but only in some cases). For example,
284 you cannot mount two images from a WIM read-write at the same time.
286 Some functions have been reorganized:
287 * wimlib_mount() renamed to wimlib_mount_image().
288 * wimlib_unmount() renamed to wimlib_unmount_image().
289 * wimlib_overwrite_xml_and_header() removed as
290 wimlib_overwrite() suffices now.
291 * wimlib_apply_image_to_ntfs_volume() removed as
292 wimlib_extract_image() suffices now.
293 * wimlib_add_image_from_ntfs_volume() removed as
294 * wimlib_add_image() suffices now.
296 Previously, the soname of libwim.so has been 0.0.0, despite many
297 interface changes. The soname is now updated to 1.0.0 and will now be
298 updated each release.
301 Resources will now be compressed using multiple threads by default.
302 (This applies to `imagex capture', `imagex append', and `imagex
305 Some performance improvements in mounted WIMs.
307 More progress information is shown when capturing a WIM.
310 Lots of minor fixes, code cleanups, and some documentation updates.
311 Nothing in particular is really noteworthy.
314 LZX and XPRESS compression improvements.
316 Fixed calculation of Directory Count, File Count, Total Bytes, and Hard
317 Link Bytes of the WIM.
320 Fixed bug when capturing NTFS file with multiple named data streams.
322 Internally, we are now using inode structures, even though these don't
323 appear literally in the WIM file. This simplifies some of the code
324 (mainly for WIM mounting) and likely fixed a few problems, although it
328 Fixed problem when exporting images from XPRESS to LZX compressed WIM or
332 Enough changes to call it version 1.0.0!
334 Capturing a WIM directly from a NTFS volume, and applying a WIM directly
335 to a NTFS volume, is now supported.
337 Hard links and symbolic links have much improved support. They are
338 supported for WIM capture, WIM application, and mounted WIMs (you can
339 even make them on read-write mounted WIMs).
341 Alternate data streams are now supported on mounted WIMs through an
342 xattr or a Windows-style stream interface. Also they are supported when
343 capturing a WIM from NTFS or applying a WIM to NTFS.
345 Split WIMs are better supported. You may now apply an image directly
346 from a split WIM, mount an image from a split WIM read-only, or export
347 an image from a split WIM.
349 Using a capture configuration file is now supported (but not fully yet).
351 SHA1 message digests are checked in more places, so we can make sure
352 applied and captured data is correct.
354 Man pages have been updated and consolidated.
357 Fixed segfault when unmounting read-only WIM.
360 Support for joining and splitting WIMs.
361 Also, security data is now preserved by default.
364 Can now build with older gcc and system headers, like on CentOS 5.
367 Fixed bug that made it impossible to overwrite files in read-write
371 Write byte-order mark before WIM XML data. (imagex.exe requires this to
