* Correctly check if CXXFLAGS is set
* Include <functional> to fix build failure on Windows
* fix warnings, fix#36
* fix#111
* fix#114 by checking for header payloads greater than max file size
* some additional checks to prevent an infinite loop when presented with certain corrupt files. Also fixing CI.
* make automake not to install `test_invariants'
OBS-URL: https://build.opensuse.org/package/show/Archiving/lepton?expand=0&rev=29
* only assert similarity of last_dc if segment_size > 1 since the overhang byte will clobber any incorrect value
* only exit on encode for items that could hazard a divide by zero on decode
* relax strictness in singlethreaded decompression mode, otherwise we are checking items that multithread mode cannot validate
* check hpos before reading from hdrs-size array
* initialize hdr memory to zero when allocating
* Fix#110 by providing a more explicit error message
* fix permissive mode on windows

* include version.hh from generic compressor
* process md5 of entire input, even if subprocess fails. cap out max generic lepton file at 32 megs: users can concatenate files to make larger generic files
* turn on seccomp for generic lepton compression
* Relax criteria for Huffman table existence check
* Fix#101 by allowing a permissive flag to accept any type of nonstandard jpeg and create a valid lepton file to represent a bitexact copy of the nonstandard jpeg
* integrate concatenation test suite into the make check system
* test suite for new mechanisms
* fix concatenation of permissive lepton files
* better header allowing for multithreaded decoding of the jpeg
* more permissive with small files and no random SIGPIPE or other hurried subprocess error codes from larger ones
* prototyping a new version of lepton that can compress arbitrary images or files by having a fallback path to encode data in a passthrough manner
* unless EOF reached, read next header in addition to the current buffer--this lets us consume all data even if we never have a desire to read past the end
* put ANS behind an experimental feature flag
* Have all inter-thread communication use the same length buffers so we can distinguish between extra data after threads have closed and new types of work
* tweaks to observation and update paremeters to make them slightly faster
* initialize last pointer for packet reader
* this worked a little too well.. call me skeptical
* instantiate some ans functions
* tests pass by keeping the boolwriters in scope until threads have been joined upon: do so by refactoring function so duplicate code would be in thhreaded_encode_inner and ANSBoolWriter can also lean on that templatized function
* Add BoolDecoder and BoolEncoder as template arguments rather than as toplevel defines. This required a significant amount of threading of the BoolDecoder through each of the state classes
* add unit test for ans bool reader and writer
* move to 512 resolution probability space (considering reducing resolution on 256 instead--but lets get correctness first
* simplify some of the flushing behavior
* link to ANS encoder
* avoid required size from zlib0 plugin

* Fix#91 by adding asserts that the garbage data is never more or equal to the full file size
* Fix#90 by checking for nonzero width/height
* deal with malformed lepton files that have incorrect ThreadHandoff sizes
* Fix#95 by adding a workaround for GCC bug https://gcc.gnu.org/bugzilla/show_bug.cgi?id=81015 that breaks builtin_clz. Also made every run of lepton error out if bitlen(1024) != 11
* pin local brotli dep
* first cut at brotli support
* add missing files
* fix brotli compression: add test for brotli header compression
* quality 9 uses too much memory--move to quality 10--which seems to be more acceptible for memory consumption
* can now produce a .lep file that represents a file with a single embedded jpeg within
* fix verification to properly understand embedded files (by blanking out the -embedding command line flag on decode) on OSX and linux. Add a test for embedding
* add an EOF marker at the end of any stream, so that we don't intrude upon concatenated lepton files
* process files one-by-one if they are concatenated together. Current failure upon threads reading second work-items
* resetting works for concatenation of 2x the same file
* fix single-threaded decode of two copies of the same image concatenated
* clear grbgdata and prefix data between runs
* proper deallocation of grbgdata
* account for some variations between the first and second file by calling reset_buffers
* clear min_noise_threshold if it would be <= 0, so that a second runthrough doesn't reuse previously set values
* allow number of threads to taper off over time
* max and min encode threads so you can force a particular thread count for a file....will help with multi-file concatenations where you want a single thread count everywhere
* get rid of printf
* do not specify a thread count outside [minthread,maxthread] range
* fix some memory leaks between decodes of concatenated lepton files
* teach lepton to understand concatenated huffman tables, JPEG headers, prefix or postfix junk etc...
* lepcat mode that can concatenate two .lep images together in a more efficient way by putting all header material in the same place
* checks to make sure files are compatible before concatenation
* Move concatenation code into its own header
* fix llvm build
OBS-URL: https://build.opensuse.org/package/show/Archiving/lepton?expand=0&rev=25
* explicitly make padbit signed. Try to fix some quirks in cmake for powerpc
* make autotools use sane default compiler flags if none are provided in the command line
* on ppc when -std=c++11 is defined, the __linux macro goes away
* added documentation to seeming typo
* fix#87 : always check that threads_required set up the appropriate number of threads---fire off nop functions on unused threads for consistency
* check divide by zero, fixing #86
* only build -scalar in ppc case
OBS-URL: https://build.opensuse.org/package/show/Archiving/lepton?expand=0&rev=21
* make sockettester and forktester python3 compatible
* Ensure proc.terminate() is called after unit test
* ioutil: poll.h -> sys/select.h
* close opened file descriptors properly
* Revert "close opened file descriptors properly"
* resource leak: fp
* Fix posix_memalign call
* Added missing 'defined'.
OBS-URL: https://build.opensuse.org/package/show/Archiving/lepton?expand=0&rev=14
* Added wrapper libraries section to README

* removing the extension
* fixes for #47 : i386 compat
* Add php bindings notice to README.md

* /build for .gitignore
* 64-bit-related fixes
* Win32 build improvements
* Fixed types to be 32-bit in all cases, fixed comments
* Unified types
* remove unused components of zlib
* it builds now, but will it run; the way things are going I don't know...
