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.
10 Joining a WIM will now preserve the RP_FIX and READONLY flags.
13 On Windows, paths given to wimlib-imagex are now treated case
16 Improved behavior regarding invalid filenames; in particular, on
17 Windows, wimlib-imagex will, when extracting, now omit (with an option
18 to override this default) filenames differing only in case, or filenames
19 containing characters not valid on Windows.
21 On Windows, wimlib now supports capturing and extracting long paths
22 (longer than the so-called MAX_PATH).
24 On Windows, `wimlib-imagex update' now acquires proper privileges when
25 running as an Administrator.
27 `wimlib-imagex update' will now complain if no image is specified when
28 trying to update a multi-image WIM.
30 `wimlib-imagex update' now supports specifying a single update command
31 directly on the command line using the --command option.
33 wimlib-imagex will now choose different units for progress messages,
34 depending on the amount of data that needs to be processed.
36 `wimlib-imagex append' will now generate a unique WIM image name if no
37 name is specified and the defaulted name already exists in the WIM.
39 wimlib now allows you to create unnamed WIM images, which can then only
40 be referred to by index.
42 wimlib now allows you to explicitly declare you want write access to a
43 WIM by providing the WIMLIB_OPEN_FLAG_WRITE_ACCESS flag to
46 wimlib now respects the WIM_HDR_FLAG_READONLY flag when set in the WIM
49 Progress callbacks have been added to wimlib's wimlib_update_image()
52 Added wimlib_get_wim_info(), wimlib_set_wim_info(),
53 wimlib_iterate_dir_tree(), and wimlib_iterate_lookup_table() functions
56 NTFS-3g capture now only warns about two conditions previously treated
59 Fixed a couple issues with using wimlib-imagex on UDF filesystems on
62 wimlib now correctly detects and returns an error when reading a WIM
63 image with a cyclic directory structure. (Fun fact: such a WIM will
64 crash Microsoft's software.)
67 Added new "extract" and "update" subcommands to wimlib-imagex, along
68 with associated APIs in the library. These commands are intended mainly
69 for Windows use but can be used on UNIX as well.
71 Many documentation improvements.
73 Fixed a bug in the Windows build where relative symbolic links were not
74 captured in reparse-point fixup mode.
76 Fixed a bug in the Windows build where file handles were left open to
77 the WIM file, causing `wimlib_imagex optimize' to fail in some cases.
79 Fixed a bug in the Windows build of wimlib-imagex where globbing
80 split-WIM parts could cause the program to crash.
82 Fixed a bug where the creation time of WIM images would be shown instead
83 of the last modification time.
85 With the Windows build it is now possible to restore a WIM containing
86 symbolic links as a non-Administrator; however you will receive warnings
87 about not being able to extract the symbolic links.
90 Capturing a WIM image should now be significantly faster in most cases
91 due to improved use of the operating system's cache and avoiding reading
92 files twice whenever possible.
94 The Windows build should now work on Windows XP.
96 The Windows build now supports capturing and restoring hidden,
97 compressed, sparse, and encrypted files.
99 The Windows build now supports capturing and applying WIM images from
100 filesystems other than NTFS (with some reduced functionality).
102 The Windows build now extracts short names correctly.
104 Added support for "reparse-point" fixups (i.e. fixing up of symbolic
105 links). See docs for --rpfix and --norpfix flags of `wimlib-imagex
106 capture' and `wimlib-imagex apply'.
108 The performance of splitting and joining WIMs should be slightly
111 The LZX and XPRESS compression and decompression functions are now
112 exported from the library.
115 Improvements and bugfixes for the Windows build.
117 Added --strict-acls options.
119 Fixed the way that wimlib determines the order of images in the WIM.
122 Since wimlib can now be used on Windows, wimlib's implementation of
123 ImageX has been renamed to wimlib-imagex to avoid confusion with
124 Microsoft's implementation of ImageX, which would have the same file
125 name ("imagex.exe"). If you really don't like this you can pass the
126 --with-imagex-progname option to `configure' to choose a different name,
127 or even simply rename the binary yourself (but the former way will
128 configure the man pages to use the chosen name).
130 Various bugs fixed in the Windows build. Mainly to do with capturing
131 and restoring alternate data streams correctly in weird cases, and
132 requesting the correct privileges when opening files. Also added the
133 --noacls options to wimlib-imagex capture, append, and apply.
135 Windows build again: FindFirstStreamW() and FindNextStreamW() are now
136 dynamically loaded, so this may make the library compatible with Windows
137 XP (however, there may still be other problems).
140 Added experimental support for native Windows builds. Binaries can be
141 downloaded from the SourceForge page.
143 --source-list option added to `imagex capture' and `imagex append'.
145 Better support for different character encodings.
148 Storing UNIX file owners, groups, and modes in WIM images is now
149 possible using `imagex capture' with the --unix-data flag.
151 Minor bug fixes and documentation fixes.
154 NTFS capture: Fixed capturing duplicate reparse points.
156 NTFS capture: Capture first unnamed stream if there are more than one
157 (print warning instead of error).
159 Allow multiple test cases to execute concurrently (e.g. make -j2 check).
162 Added --arch switch to mkwinpeimg script to support getting AMD64 WinPE
165 Update to work with ntfs-3g version 2013.1.13.
168 Fixed truncating file to shorter but non-zero length on read-write
171 Various code cleanups and minor documentation fixes.
174 LZX and XPRESS decompression have received some additional optimizations
175 and should now be even faster. (Although, they were already pretty
176 fast--- much faster than typical I/O speeds.)
178 Fixed a bug introduced in v1.2.1 that would cause a directory tree
179 containing hard links to be captured incorrectly in some cases.
182 By default, unmounting a read-write mounted WIM with 'imagex unmount
183 --commit' will now change the WIM in-place without needing to write the
184 entire WIM again. Use 'imagex unmount --commit --rebuild' to get the
187 'imagex unmount' no longer has a hard-coded limit of 10 minutes to wait
188 for a response from the daemon servicing the mounted WIM. Instead,
189 every second 'imagex unmount' will check if the daemon is still alive,
190 and keep waiting if so, otherwise terminate with an error.
192 'imagex unmount --commit' on a read-write mounted WIM will now print
193 progress information regarding the writing of new or modified streams
194 the WIM, just like when capturing or appending a WIM.
196 A small change has been made to XPRESS compression and it should improve
197 the compression ratio slightly.
199 A change was made that may improve performance slightly when applying a
200 WIM image to a NTFS volume.
202 Microsoft has managed to introduce even more bugs into their software,
203 and now the WIMs for Windows 8 have incorrect (too low) reference counts
204 for some streams. This is unsafe because such streams can be removed
205 when they are in actuality still referenced in the WIM (perhaps by a
206 different image). wimlib will now work around this problem by fixing
207 the stream reference counts. This is only done when wimlib_delete_image() is
208 called ('imagex delete') or when wimlib_mount_image() is called with
209 WIMLIB_MOUNT_FLAG_READWRITE ('imagex mountrw'). Please note that this
210 requires reading the metadata for all images in the WIM, so this will
211 make these operations noticably slower on WIMs with multiple images.
213 Various other bugfixes.
216 Appending images to a WIM is now be done by default without re-building
217 the whole WIM. Use the --rebuild flag to get the old behavior (which
218 was to re-build the entire WIM when a new image is appended).
220 A new command `imagex optimize' is now available to manually re-build a
221 WIM that has wasted space due to repeated appends.
223 Progress information has been improved, and now arbitrary callback
224 functions can be used to show the progress of a WIM operation.
226 A possible bug with changing the bootable image of a WIM was fixed.
228 Some advisory locking is now done to prevent two processes from
229 modifying a WIM at the same time (but only in some cases). For example,
230 you cannot mount two images from a WIM read-write at the same time.
232 Some functions have been reorganized:
233 * wimlib_mount() renamed to wimlib_mount_image().
234 * wimlib_unmount() renamed to wimlib_unmount_image().
235 * wimlib_overwrite_xml_and_header() removed as
236 wimlib_overwrite() suffices now.
237 * wimlib_apply_image_to_ntfs_volume() removed as
238 wimlib_extract_image() suffices now.
239 * wimlib_add_image_from_ntfs_volume() removed as
240 * wimlib_add_image() suffices now.
242 Previously, the soname of libwim.so has been 0.0.0, despite many
243 interface changes. The soname is now updated to 1.0.0 and will now be
244 updated each release.
247 Resources will now be compressed using multiple threads by default.
248 (This applies to `imagex capture', `imagex append', and `imagex
251 Some performance improvements in mounted WIMs.
253 More progress information is shown when capturing a WIM.
256 Lots of minor fixes, code cleanups, and some documentation updates.
257 Nothing in particular is really noteworthy.
260 LZX and XPRESS compression improvements.
262 Fixed calculation of Directory Count, File Count, Total Bytes, and Hard
263 Link Bytes of the WIM.
266 Fixed bug when capturing NTFS file with multiple named data streams.
268 Internally, we are now using inode structures, even though these don't
269 appear literally in the WIM file. This simplifies some of the code
270 (mainly for WIM mounting) and likely fixed a few problems, although it
274 Fixed problem when exporting images from XPRESS to LZX compressed WIM or
278 Enough changes to call it version 1.0.0!
280 Capturing a WIM directly from a NTFS volume, and applying a WIM directly
281 to a NTFS volume, is now supported.
283 Hard links and symbolic links have much improved support. They are
284 supported for WIM capture, WIM application, and mounted WIMs (you can
285 even make them on read-write mounted WIMs).
287 Alternate data streams are now supported on mounted WIMs through an
288 xattr or a Windows-style stream interface. Also they are supported when
289 capturing a WIM from NTFS or applying a WIM to NTFS.
291 Split WIMs are better supported. You may now apply an image directly
292 from a split WIM, mount an image from a split WIM read-only, or export
293 an image from a split WIM.
295 Using a capture configuration file is now supported (but not fully yet).
297 SHA1 message digests are checked in more places, so we can make sure
298 applied and captured data is correct.
300 Man pages have been updated and consolidated.
303 Fixed segfault when unmounting read-only WIM.
306 Support for joining and splitting WIMs.
307 Also, security data is now preserved by default.
310 Can now build with older gcc and system headers, like on CentOS 5.
313 Fixed bug that made it impossible to overwrite files in read-write
317 Write byte-order mark before WIM XML data. (imagex.exe requires this to
