The new Minalign field sets the minimum alignment for all symbols. This is required for the upcoming s390x port which requires symbols be 2-byte aligned for efficient relative addressing. All preexisting architectures have Minalign set to 1 which means that this commit should have no effect. I tested values of 2, 4 and 8 on linux amd64 and the tests appear to pass. Increasing Minalign to 16 appears to break the runtime. I think this is due to assumptions made about the layout of module data. toolstash -cmp on linux amd64 shows no changes due to this commit.

Over the years as more bugs were discovered with the bzip2 library, new Tests were appended the unit tests and the tests became gnarly. Clean up the tests to be more consistent with modern Go style in addition to coalescing common tests into a general version that iterates over a list of input/output pairs. This has the advantage that the input, output, and test code are all in the same area, rather than being sprawled around the test file. There is no loss of test coverage.

This promotes a connection hang during TLS handshake to a proper error. This doesn't fully address #14539 because the error reported in that case is a write-on-socket-not-connected error, which implies that an earlier error during connection setup is not being checked, but it is an improvement over the current behaviour.

Unlike RFC 1951 (DEFLATE), bzip2 does not use zero-length Huffman codes to indicate that the symbol is missing. Instead, bzip2 uses a sparse bitmap to indicate which symbols are present. Thus, it is undefined what happens when a length of zero is used. Thus, fix the parsing logic so that the length cannot ever go below 1-bit similar to how the C logic does things. To confirm that the C bzip2 utility chokes on this data: $ echo "425a6836314159265359b1f7404b000000400040002000217d184682ee48 a70a12163ee80960" | xxd -r -p | bzip2 -d bzip2: Data integrity error when decompressing For reference see: bzip2-1.0.6/decompress.c:320 Change-Id: Ic1568f8e7f80cdea51d887b4d712cc239c2fe85e Reviewed-on: https://go-review.googlesource.com/20119 Run-TryBot: Joe Tsai <joetsai@digital-static.net> TryBot-Result: Gobot Gobot <gobot@golang.org> Reviewed-by:

This per-symbol table was written with the strategy: 1. record offset and write fake header 2. write body 3. seek back to fake header 4. write real header This CL collects the per-symbol body into a []byte, then writes the real header followed by the body to the output file. This saves two seeks per-symbol and overwriting the fake header.

The size calculation has been wrong since this code was first committed in https://golang.org/cl/3120. The effect was that the compiler always allocated a temporary buffer on the stack for a non-escaping string concatenation. This turns out to make no practical difference, as the compiler always allocates a buffer of the same size (32 bytes) and the runtime only uses the temporary buffer if the concatenated strings fit (check is in rawstringtmp in runtime/string.go). The effect of this change is to avoid generating a temporary buffer on the stack that will not be used.
