On the one hand, this\nrestriction is not useful for decoders: the decoder must nonetheless be\nprepared to accept compressed blocks that are the full\n`Block_Maximum_Decompressed_Size`. And on the other, this bound is actually\nartificially limiting. If block representations were entirely independent,\na compressed representation of a block that is larger than the contents of the\nblock would be ipso facto useless, and it would be strictly better to send it\nas an `Raw_Block`. However, blocks are not entirely independent, and it can\nmake sense to pay the cost of encoding custom entropy tables in a block, even\nif that pushes that block size over the size of the data it represents,\nbecause those tables can be re-used by subsequent blocks.\n\nFinally, as far as I can tell, this restriction in the spec is not currently\nenforced in any Zstandard implementation, nor has it ever been. This change\nshould therefore be safe to make.\n" }, { "commit": "9bf00707c7db33fb1ab4ae5dced1caacb09433a5", "tree": "6ac89f53caa5a863c2871e89067115f373fa1fae", "parents": [ "c3c7deb1e1efea05d323a3698c4a4c53d1a3460b" ], "author": { "name": "Yann Collet", "email": "cyan@fb.com", "time": "Fri Oct 26 15:51:51 2018 -0700" }, "committer": { "name": "Yann Collet", "email": "cyan@fb.com", "time": "Fri Oct 26 15:51:51 2018 -0700" }, "message": "minor clarifications of history update rules\n" }, { "commit": "f0fe9b0f0298ed8e5c2eebf36e024803f176f6dd", "tree": "1c16e6d5df36362eb08786205deaec8968dc27f3", "parents": [ "4f702e44457508122e249109170452d89decb971" ], "author": { "name": "Ulrich Kunitz", "email": "ulikunitz@users.noreply.github.com", "time": "Tue Oct 23 08:43:19 2018 +0200" }, "committer": { "name": "Ulrich Kunitz", "email": "ulikunitz@users.noreply.github.com", "time": "Tue Oct 23 08:43:19 2018 +0200" }, "message": "Reverted removal of a trailing space.\n\nMy editor removes trailing spaces while saving.
