2017-04-21liblzma: Rename LZMA_SEEK to LZMA_SEEK_NEEDED and seek_in to seek_pos.Lasse Collin1-9/+9
2017-03-30liblzma: Add generic support for input seeking (LZMA_SEEK).Lasse Collin1-1/+30
Also mention LZMA_SEEK in xz/message.c to silence a warning.
2017-03-30liblzma: Fix lzma_memlimit_set(strm, 0).Lasse Collin1-1/+6
The 0 got treated specially in a buggy way and as a result the function did nothing. The API doc said that 0 was supposed to return LZMA_PROG_ERROR but it didn't. Now 0 is treated as if 1 had been specified. This is done because 0 is already used to indicate an error from lzma_memlimit_get() and lzma_memusage(). In addition, lzma_memlimit_set() no longer checks that the new limit is at least LZMA_MEMUSAGE_BASE. It's counter-productive for the Index decoder and was actually needed only by the auto decoder. Auto decoder has now been modified to check for LZMA_MEMUSAGE_BASE.
2013-10-02liblzma: Add LZMA_FULL_BARRIER support to single-threaded encoder.Lasse Collin1-7/+30
In the single-threaded encoder LZMA_FULL_BARRIER is simply an alias for LZMA_FULL_FLUSH.
2012-12-14Make the progress indicator smooth in threaded mode.Lasse Collin1-1/+21
This adds lzma_get_progress() to liblzma and takes advantage of it in xz. lzma_get_progress() collects progress information from the thread-specific structures so that fairly accurate progress information is available to applications. Adding a new function seemed to be a better way than making the information directly available in lzma_stream (like total_in and total_out are) because collecting the information requires locking mutexes. It's waste of time to do it more often than the up to date information is actually needed by an application.
2012-07-17liblzma: Make the use of lzma_allocator const-correct.Lasse Collin1-1/+3
There is a tiny risk of causing breakage: If an application assigns lzma_stream.allocator to a non-const pointer, such code won't compile anymore. I don't know why anyone would do such a thing though, so in practice this shouldn't cause trouble. Thanks to Jan Kratochvil for the patch.
2011-04-11liblzma: API comment about lzma_allocator with threaded coding.Lasse Collin1-5/+13
2010-10-23liblzma: A few ABI tweaks to reserve space in structures.Lasse Collin1-1/+6
2010-10-21liblzma: Update the comments in the API headers.Lasse Collin1-19/+19
Adding support for LZMA_FINISH for Index encoding and decoding needed tiny additions to the relevant .c files too.
2010-02-12Collection of language fixes to comments and docs.Lasse Collin1-4/+4
Thanks to Jonathan Nieder.
2009-08-27Updates to liblzma API headers.Lasse Collin1-22/+26
Added lzma_nothrow for every function. It adds throw() when the header is used in C++ code. Some lzma_attrs were added or removed. Lots of comments were improved.
2009-04-13Put the interesting parts of XZ Utils into the public domain.Lasse Collin1-12/+8
Some minor documentation cleanups were made at the same time.
2009-02-02Modify LZMA_API macro so that it works on Windows withLasse Collin1-5/+6
other compilers than MinGW. This may hurt readability of the API headers slightly, but I don't know any better way to do this.
2009-02-01Use __cdecl also for function pointers in liblzma API whenLasse Collin1-2/+2
on Windows.
2009-01-31Add LZMA_API to liblzma API headers. It's useful at leastLasse Collin1-5/+5
on Windows. sysdefs.h no longer #includes lzma.h, so lzma.h has to be #included separately where needed.
2008-12-15Bunch of liblzma API cleanups and fixes.Lasse Collin1-61/+113
2008-09-13Renamed constants:Lasse Collin1-2/+2
- LZMA_VLI_VALUE_MAX -> LZMA_VLI_MAX - LZMA_VLI_VALUE_UNKNOWN -> LZMA_VLI_UNKNOWN - LZMA_HEADER_ERRRO -> LZMA_OPTIONS_ERROR

2008-09-06Some API cleanupsLasse Collin1-113/+201
2008-08-28Sort of garbage collection commit. :-| Many things are stillLasse Collin1-28/+33
broken. API has changed a lot and it will still change a little more here and there. The command line tool doesn't have all the required changes to reflect the API changes, so it's easy to get "internal error" or trigger assertions.
2008-06-18Update the code to mostly match the new simpler file formatLasse Collin1-0/+15
specification. Simplify things by removing most of the support for known uncompressed size in most places. There are some miscellaneous changes here and there too. The API of liblzma has got many changes and still some more will be done soon. While most of the code has been updated, some things are not fixed (the command line tool will choke with invalid filter chain, if nothing else). Subblock filter is somewhat broken for now. It will be updated once the encoded format of the Subblock filter has been decided.
2008-04-28Fixed wrong spelling "limitter" to "limiter". This affectsLasse Collin1-2/+2
liblzma's API.
