* First building commit with sample matchfinder * Set up ZSTD_externalMatchCtx struct * move seqBuffer to ZSTD_Sequence* * support non-contiguous dictionary * clean up parens * add clearExternalMatchfinder, handle allocation errors * Add useExternalMatchfinder cParam * validate useExternalMatchfinder cParam * Disable LDM + external matchfinder * Check for static CCtx * Validate mState and mStateDestructor * Improve LDM check to cover both branches * Error API with optional fallback * handle RLE properly for external matchfinder * nit * Move to a CDict-like model for resource ownership * Add hidden useExternalMatchfinder bool to CCtx_params_s * Eliminate malloc, move to cwksp allocation * Handle CCtx reset properly * Ensure seqStore has enough space for external sequences * fix capitalization * Add DEBUGLOG statements * Add compressionLevel param to matchfinder API * fix c99 issues and add a param combination error code * nits * Test external matchfinder API * C90 compat for simpleExternalMatchFinder * Fix some @nocommits and an ASAN bug * nit * nit * nits * forward declare copySequencesToSeqStore functions in zstd_compress_internal.h * nit * nit * nits * Update copyright headers * Fix CMake zstreamtest build * Fix copyright headers (again) * typo * Add externalMatchfinder demo program to make contrib * Reduce memory consumption for small blockSize * ZSTD_postProcessExternalMatchFinderResult nits * test sum(matchlen) + sum(litlen) == srcSize in debug builds * refExternalMatchFinder -> registerExternalMatchFinder * C90 nit * zstreamtest nits * contrib nits * contrib nits * allow block splitter + external matchfinder, refactor * add windowSize param * add contrib/externalMatchfinder/README.md * docs * go back to old RLE heuristic because of the first block issue * fix initializer element is not a constant expression * ref contrib from zstd.h * extremely pedantic compiler warning fix, meson fix, typo fix * Additional docs on API limitations * minor nits * Refactor maxNbSeq calculation into a helper function * Fix copyright
