* dpkg: fix CONFIG_FEATURE_CLEAN_UP handlingPeter Korsgaard2017-07-051-4/+0
| | | | | | | | | | | | | dpkg moved to away from dynamically allocating the hashtables in commit c87339d584 (dpkg: trivial code shrinkage, and redo G trick correctly) almost ten years ago, but the cleanup code was never adjusted to match. Glibc loudly complains about this: *** Error in `dpkg': free(): invalid pointer: 0x0000007fac3478c0 *** Signed-off-by: Peter Korsgaard <peter@korsgaard.com> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>

* unlzma: fix erroneous "while" instead of "if". Closes 4682Denys Vlasenko2017-01-091-5/+8
| | | | | | | | | | | | | | | | | | | | | | | | These parts of the code essentially check whether stepping back by rep0 goes negative or not. LZMA SDK from lzma1604.7z has the following in the corresponding places: ... = dic[dicPos - rep0 + (dicPos < rep0 ? dicBufSize : 0)] Clearly, not loop here. Technically, "while" here works: if condition is false (because pos underflowed), it iterates once, adds header.dict_size (a.k.a. dicBufSize), this makes pos positive but smaller than header.dict_size, and loop exits. Now we'll just check for negative result of subtraction, which is less code: function old new delta unpack_lzma_stream 2659 2641 -18 (I hope 2 Gbyte+ dictionaries won't be in use soon).

* bunzip2: fix code bloat caused by zcat's seamless magicKang-Che Sung2017-01-081-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | This example single-applet configuration would trigger the bloat: CONFIG_FEATURE_SEAMLESS_XZ=y CONFIG_FEATURE_SEAMLESS_LZMA=y CONFIG_FEATURE_SEAMLESS_BZ2=y CONFIG_FEATURE_SEAMLESS_GZ=y CONFIG_BUNZIP2=y # CONFIG_ZCAT is not set # All other applets disabled Here, the resulting "busybox-bunzip2" binary would contain unpack_gz_stream, unpack_lzma_stream and unpack_xz_stream functions code. In other words, the gzip, lzma and xz decompressors' code are linked into the binary unnecessarily. This happens because SEAMLESS_MAGIC != 0 and compiler is unable to figure out that SEAMLESS_MAGIC bit is never set. Fix this by disabling SEAMLESS_MAGIC option flag (setting its value to 0) when zcat is disabled. This will help the compiler optimize out bbunpack() and no longer generate open_zipped() function call.

| | | | | | | | | | | | | | | | | fix broken logic to get the gzip_level_config value from options -1 to -9. This fixes an off-by-one bug that caused gzip -9 output bigger files than the other compression levels. It fixes so that compression level 1 to 3 are actually mapped to level 4 as comments say. It also fixes that levels -4 to -9 is mapped to correct level and avoids out-of-bounds access.
