1 Only the most important changes more recent than version 0.6 are noted here.
4 Fixed bug in `wimlib-imagex export' that made it impossible to export an
5 image from a WIM that is readonly at the filesystem level.
7 Return error code rather than segfaulting when trying to list files from
8 a non-first part of a split WIM.
11 On Windows, paths given to wimlib-imagex are now treated case
14 Improved behavior regarding invalid filenames; in particular, on
15 Windows, wimlib-imagex will, when extracting, now omit (with an option
16 to override this default) filenames differing only in case, or filenames
17 containing characters not valid on Windows.
19 On Windows, wimlib now supports capturing and extracting long paths
20 (longer than the so-called MAX_PATH).
22 On Windows, `wimlib-imagex update' now acquires proper privileges when
23 running as an Administrator.
25 `wimlib-imagex update' will now complain if no image is specified when
26 trying to update a multi-image WIM.
28 `wimlib-imagex update' now supports specifying a single update command
29 directly on the command line using the --command option.
31 wimlib-imagex will now choose different units for progress messages,
32 depending on the amount of data that needs to be processed.
34 `wimlib-imagex append' will now generate a unique WIM image name if no
35 name is specified and the defaulted name already exists in the WIM.
37 wimlib now allows you to create unnamed WIM images, which can then only
38 be referred to by index.
40 wimlib now allows you to explicitly declare you want write access to a
41 WIM by providing the WIMLIB_OPEN_FLAG_WRITE_ACCESS flag to
44 wimlib now respects the WIM_HDR_FLAG_READONLY flag when set in the WIM
47 Progress callbacks have been added to wimlib's wimlib_update_image()
50 Added wimlib_get_wim_info(), wimlib_set_wim_info(),
51 wimlib_iterate_dir_tree(), and wimlib_iterate_lookup_table() functions
54 NTFS-3g capture now only warns about two conditions previously treated
57 Fixed a couple issues with using wimlib-imagex on UDF filesystems on
60 wimlib now correctly detects and returns an error when reading a WIM
61 image with a cyclic directory structure. (Fun fact: such a WIM will
62 crash Microsoft's software.)
65 Added new "extract" and "update" subcommands to wimlib-imagex, along
66 with associated APIs in the library. These commands are intended mainly
67 for Windows use but can be used on UNIX as well.
69 Many documentation improvements.
71 Fixed a bug in the Windows build where relative symbolic links were not
72 captured in reparse-point fixup mode.
74 Fixed a bug in the Windows build where file handles were left open to
75 the WIM file, causing `wimlib_imagex optimize' to fail in some cases.
77 Fixed a bug in the Windows build of wimlib-imagex where globbing
78 split-WIM parts could cause the program to crash.
80 Fixed a bug where the creation time of WIM images would be shown instead
81 of the last modification time.
83 With the Windows build it is now possible to restore a WIM containing
84 symbolic links as a non-Administrator; however you will receive warnings
85 about not being able to extract the symbolic links.
88 Capturing a WIM image should now be significantly faster in most cases
89 due to improved use of the operating system's cache and avoiding reading
90 files twice whenever possible.
92 The Windows build should now work on Windows XP.
94 The Windows build now supports capturing and restoring hidden,
95 compressed, sparse, and encrypted files.
97 The Windows build now supports capturing and applying WIM images from
98 filesystems other than NTFS (with some reduced functionality).
100 The Windows build now extracts short names correctly.
102 Added support for "reparse-point" fixups (i.e. fixing up of symbolic
103 links). See docs for --rpfix and --norpfix flags of `wimlib-imagex
104 capture' and `wimlib-imagex apply'.
106 The performance of splitting and joining WIMs should be slightly
109 The LZX and XPRESS compression and decompression functions are now
110 exported from the library.
113 Improvements and bugfixes for the Windows build.
115 Added --strict-acls options.
117 Fixed the way that wimlib determines the order of images in the WIM.
120 Since wimlib can now be used on Windows, wimlib's implementation of
121 ImageX has been renamed to wimlib-imagex to avoid confusion with
122 Microsoft's implementation of ImageX, which would have the same file
123 name ("imagex.exe"). If you really don't like this you can pass the
124 --with-imagex-progname option to `configure' to choose a different name,
125 or even simply rename the binary yourself (but the former way will
126 configure the man pages to use the chosen name).
128 Various bugs fixed in the Windows build. Mainly to do with capturing
129 and restoring alternate data streams correctly in weird cases, and
130 requesting the correct privileges when opening files. Also added the
131 --noacls options to wimlib-imagex capture, append, and apply.
133 Windows build again: FindFirstStreamW() and FindNextStreamW() are now
134 dynamically loaded, so this may make the library compatible with Windows
135 XP (however, there may still be other problems).
138 Added experimental support for native Windows builds. Binaries can be
139 downloaded from the SourceForge page.
141 --source-list option added to `imagex capture' and `imagex append'.
143 Better support for different character encodings.
146 Storing UNIX file owners, groups, and modes in WIM images is now
147 possible using `imagex capture' with the --unix-data flag.
149 Minor bug fixes and documentation fixes.
152 NTFS capture: Fixed capturing duplicate reparse points.
154 NTFS capture: Capture first unnamed stream if there are more than one
155 (print warning instead of error).
157 Allow multiple test cases to execute concurrently (e.g. make -j2 check).
160 Added --arch switch to mkwinpeimg script to support getting AMD64 WinPE
163 Update to work with ntfs-3g version 2013.1.13.
166 Fixed truncating file to shorter but non-zero length on read-write
169 Various code cleanups and minor documentation fixes.
172 LZX and XPRESS decompression have received some additional optimizations
173 and should now be even faster. (Although, they were already pretty
174 fast--- much faster than typical I/O speeds.)
176 Fixed a bug introduced in v1.2.1 that would cause a directory tree
177 containing hard links to be captured incorrectly in some cases.
180 By default, unmounting a read-write mounted WIM with 'imagex unmount
181 --commit' will now change the WIM in-place without needing to write the
182 entire WIM again. Use 'imagex unmount --commit --rebuild' to get the
185 'imagex unmount' no longer has a hard-coded limit of 10 minutes to wait
186 for a response from the daemon servicing the mounted WIM. Instead,
187 every second 'imagex unmount' will check if the daemon is still alive,
188 and keep waiting if so, otherwise terminate with an error.
190 'imagex unmount --commit' on a read-write mounted WIM will now print
191 progress information regarding the writing of new or modified streams
192 the WIM, just like when capturing or appending a WIM.
194 A small change has been made to XPRESS compression and it should improve
195 the compression ratio slightly.
197 A change was made that may improve performance slightly when applying a
198 WIM image to a NTFS volume.
200 Microsoft has managed to introduce even more bugs into their software,
201 and now the WIMs for Windows 8 have incorrect (too low) reference counts
202 for some streams. This is unsafe because such streams can be removed
203 when they are in actuality still referenced in the WIM (perhaps by a
204 different image). wimlib will now work around this problem by fixing
205 the stream reference counts. This is only done when wimlib_delete_image() is
206 called ('imagex delete') or when wimlib_mount_image() is called with
207 WIMLIB_MOUNT_FLAG_READWRITE ('imagex mountrw'). Please note that this
208 requires reading the metadata for all images in the WIM, so this will
209 make these operations noticably slower on WIMs with multiple images.
211 Various other bugfixes.
214 Appending images to a WIM is now be done by default without re-building
215 the whole WIM. Use the --rebuild flag to get the old behavior (which
216 was to re-build the entire WIM when a new image is appended).
218 A new command `imagex optimize' is now available to manually re-build a
219 WIM that has wasted space due to repeated appends.
221 Progress information has been improved, and now arbitrary callback
222 functions can be used to show the progress of a WIM operation.
224 A possible bug with changing the bootable image of a WIM was fixed.
226 Some advisory locking is now done to prevent two processes from
227 modifying a WIM at the same time (but only in some cases). For example,
228 you cannot mount two images from a WIM read-write at the same time.
230 Some functions have been reorganized:
231 * wimlib_mount() renamed to wimlib_mount_image().
232 * wimlib_unmount() renamed to wimlib_unmount_image().
233 * wimlib_overwrite_xml_and_header() removed as
234 wimlib_overwrite() suffices now.
235 * wimlib_apply_image_to_ntfs_volume() removed as
236 wimlib_extract_image() suffices now.
237 * wimlib_add_image_from_ntfs_volume() removed as
238 * wimlib_add_image() suffices now.
240 Previously, the soname of libwim.so has been 0.0.0, despite many
241 interface changes. The soname is now updated to 1.0.0 and will now be
242 updated each release.
245 Resources will now be compressed using multiple threads by default.
246 (This applies to `imagex capture', `imagex append', and `imagex
249 Some performance improvements in mounted WIMs.
251 More progress information is shown when capturing a WIM.
254 Lots of minor fixes, code cleanups, and some documentation updates.
255 Nothing in particular is really noteworthy.
258 LZX and XPRESS compression improvements.
260 Fixed calculation of Directory Count, File Count, Total Bytes, and Hard
261 Link Bytes of the WIM.
264 Fixed bug when capturing NTFS file with multiple named data streams.
266 Internally, we are now using inode structures, even though these don't
267 appear literally in the WIM file. This simplifies some of the code
268 (mainly for WIM mounting) and likely fixed a few problems, although it
272 Fixed problem when exporting images from XPRESS to LZX compressed WIM or
276 Enough changes to call it version 1.0.0!
278 Capturing a WIM directly from a NTFS volume, and applying a WIM directly
279 to a NTFS volume, is now supported.
281 Hard links and symbolic links have much improved support. They are
282 supported for WIM capture, WIM application, and mounted WIMs (you can
283 even make them on read-write mounted WIMs).
285 Alternate data streams are now supported on mounted WIMs through an
286 xattr or a Windows-style stream interface. Also they are supported when
287 capturing a WIM from NTFS or applying a WIM to NTFS.
289 Split WIMs are better supported. You may now apply an image directly
290 from a split WIM, mount an image from a split WIM read-only, or export
291 an image from a split WIM.
293 Using a capture configuration file is now supported (but not fully yet).
295 SHA1 message digests are checked in more places, so we can make sure
296 applied and captured data is correct.
298 Man pages have been updated and consolidated.
301 Fixed segfault when unmounting read-only WIM.
304 Support for joining and splitting WIMs.
305 Also, security data is now preserved by default.
308 Can now build with older gcc and system headers, like on CentOS 5.
311 Fixed bug that made it impossible to overwrite files in read-write
315 Write byte-order mark before WIM XML data. (imagex.exe requires this to
