None.
Fixed fallthrough in getopt 'h'.
Added CHANGELOG.md.
Added comment to help explain build error when attempting to build the command line interface for embedded systems without getopt.h/err.h.
Added #ifndefs around defaults for static configuration variables
(HEATSHRINK_STATIC_INPUT_BUFFER_SIZE, HEATSHRINK_STATIC_WINDOW_BITS,
HEATSHRINK_STATIC_LOOKAHEAD_BITS, HEATSHRINK_DEBUGGING_LOGS,
HEATSHRINK_USE_INDEX). Thanks @ajaybhargav.
Use constant rather than bare int 4096 for buffer size.
Fixed fallthrough compiler warning.
Move repo into include/, src/, test/, and build in build/.
Update theft tests to match interface changes in theft.
greatest.h: Update vendored copy to 1.5.0.
Fix warnings with new version of greatest.
Fixed warnings for unreachable code on ARMCC. (Thanks @sport-climber.)
Fixed various typos, reported by @UnePierre.
Added checks and error messages when the CLI is given invalid parameters for the window or lookahead bits.
Addressed a bunch of warnings from clang's -Weverything, which
mostly had to do with mixing up numeric types.
None.
Update inaccurate assertion. (Only active when logging.)
Fix minor typo.
benchmark: Scrape file size from ls | awk -- stat & du args are less portable.
Update contact info.
The limits for the window and lookahead size options have changed. The minimum lookahead bits option (-l) is now 3 (previously, 2), and the maximum is the window bits - 1 (previously, equal to the window bits).
Change get_bits() to uint16_t.
Fix search when window size equals lookahead.
Correct encoder state machine graph.
Fix signed/unsigned comparisons.
Use consistently signed vars during index construction.
Fix debug output and asserts.
Vary window and lookahead sizes in theft tests, add a regression test. Thanks to @unixdj for finding this bug and providing very detailed info about how to reproduce it!
Simplify break even point calculation a bit further.
Clean up / dead code elimination.
Misc test cleanup.
Add compression benchmarking script.
Initial work on a CONTRIBUTING.md.
README: Add details on example usage and recommended configuration defaults.
Consistently use "decompress", not "uncompress".
None.
Fix handling of O_BINARY on Windows.
Add optional property-based tests, using theft (if available).
Fix compilation on MinGW and other platforms without err.h
Print all status messages on stderr.
Fix missing #include for getopt.h.
Complete overhaul of Makefile: both static & dynamic variant static libs.
None.
Fix possible state yielding MORE from finish(), but 0 bytes from poll().
Improve non-indexed compression performance.
When indexed, only check matches that can beat the current best match.
Only check for matches that can be improvements.
Update heatshrink_common.h filename in README.md to reflect rename.
Add usage details, homepage to heatshrink -h message.
CLI: note that compression is the default.x
Update non-indexed matching to use an int16_t pos.
Update index type to int16_t.
Decrease HEATSHRINK_MAX_WINDOW_BITS to 15.
None.
Remove unused static library target from Makefile.
Cast write(2)'s -1 to (size_t) to avoid sign mismatch warning.
Code style cleanup: always brace ifs, extract NO_BITS constant.
Eliminate redundant comparison, index ensures first byte matches.
Improve throughput of find_longest_match via several improvements
to the indexing strategy.
If calling push_bits w/ 8 bits at beginning of new byte, just copy byte over whole.
None.
None.
Renamed heatshrink.h to heatshrink_common.h, to make it more
clearly separate from the heatshrink.c CLI interface.
Don't use assert unless HEATSHRINK_DEBUGGING_LOGS is set.
Fix some (potentially) unused variable and numeric type warnings.
Add warnings from -Wextra.
Add braces around statements hanging off ifs that may compile out to no-ops.
Fix usage string ("[-v]" not "[v]").
Change from BSD-3 License to ISC License.
Reduce default static_input_buffer_size.
Update decoder state machine diagram to reflect MSB/LSB split.
Change uint16_t to size_t for user-controlled buffer sizes.
When index or count are > 8 bits long, ensure suspend/resume is correct.
Consistentcy: log to stderr for both enc and dec.
Tighten bounds for lookahead and window size.
Since they're only stored as uint16_ts, disallow overly large sizes.
Initial public release.
