2019-09-05gzip: set default compression level to 6 when CONFIG_FEATURE_GZIP_LEVELS=nDaniel Edgecumbe
With this change, GNU gzip -n and BusyBox gzip now produce identical output assuming that CONFIG_GZIP_FAST=2. >> Excuse me, but I wonder one thing: Why should we follow >> strictly with gzip on the no-options default behavior? > First, the default 6 compression level is a de-facto standard. BSD gzip > and Apple gzip (on macOS) use this default as well. So there is a > reasonable expectation that different gzip implementations act the same. > For instance, if the default for busybox gzip becomes 9, then someone > writing a script using busybox gzip could reasonably expect that the > compression level will still be 9 when the same script is run on another > system. That would be wrong. Implementations should not deviate from > de-facto standards without a strong reason. > > Second, the inherent reason for this default has not gone away. While > processor speeds have exploded since the default was set, so has the > typical size of compressed files. Multiple gigabytes are nothing unusual > these days. And gzip is often used for compression on the fly, precisely > because it offers a good compromise between speed and compression ratio. > So I believe 6 continues to be a reasonable default. function old new delta deflate 939 927 -12 Signed-off-by: Daniel Edgecumbe <git@esotericnonsense.com> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>
2019-09-05gzip: set compression flags correctly as per standardDaniel Edgecumbe
With this change and CONFIG_GZIP_FAST=2, CONFIG_FEATURE_GZIP_LEVELS=y, GNU gzip and BusyBox gzip now produce identical output at each compression level (excluding 1..3, as BusyBox does not implement these levels).

2019-07-02libbb: reduce the overhead of single parameter bb_error_msg() callsJames Byrne
Back in 2007, commit 0c97c9d43707 ("'simple' error message functions by Loic Grenie") introduced bb_simple_perror_msg() to allow for a lower overhead call to bb_perror_msg() when only a string was being printed with no parameters. This saves space for some CPU architectures because it avoids the overhead of a call to a variadic function. However there has never been a simple version of bb_error_msg(), and since 2007 many new calls to bb_perror_msg() have been added that only take a single parameter and so could have been using bb_simple_perror_message(). This changeset introduces 'simple' versions of bb_info_msg(), bb_error_msg(), bb_error_msg_and_die(), bb_herror_msg() and bb_herror_msg_and_die(), and replaces all calls that only take a single parameter, or use something like ("%s", arg), with calls to the corresponding 'simple' version. Since it is likely that single parameter calls to the variadic functions may be accidentally reintroduced in the future a new debugging config option WARN_SIMPLE_MSG has been introduced. This uses some macro magic which will cause any such calls to generate a warning, but this is turned off by default to avoid use of the unpleasant macros in normal circumstances. This is a large changeset due to the number of calls that have been replaced. The only files that contain changes other than simple substitution of function calls are libbb.h, libbb/herror_msg.c, libbb/verror_msg.c and libbb/xfuncs_printf.c. In miscutils/devfsd.c, networking/udhcp/common.h and util-linux/mdev.c additonal macros have been added for logging so that single parameter and multiple parameter logging variants exist. The amount of space saved varies considerably by architecture, and was found to be as follows (for 'defconfig' using GCC 7.4): Arm: -92 bytes MIPS: -52 bytes PPC: -1836 bytes x86_64: -938 bytes Note that for the MIPS architecture only an exception had to be made disabling the 'simple' calls for 'udhcp' (in networking/udhcp/common.h) because it made these files larger on MIPS.
