| * libbb: reduce the overhead of single parameter bb_error_msg() callsJames Byrne2019-07-021-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* | win32: fix POSIX build (again)Ron Yorston2019-03-121-1/+3
| | | | | | | | | | Some faulty logic with ENABLE_FEATURE_EXTRA_FILE_DATA broke the POSIX build.
* | win32: stat(2) succeeds if fetching extra metadata failsRon Yorston2019-02-191-2/+3
| | | | | | | | | | | | | | | | | | Some files can't be opened to fetch additional metadata. When that happens allow stat(2) to successfully return what data it has. In a few cases where the inode number is used to determine if files are identical ignore invalid inode numbers.
* | win32: make stat(2) fetch additional metadataRon Yorston2019-02-161-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Modify the WIN32 implementation of stat(2) to fetch inode number, device id and number of hardlinks. This requires opening a handle to the target file so it will be slower. A number of features can be enabled or start to work: - tar can detect if an archive is being stored in itself; - find can support the -inum and -links options; - ls can display inode numbers; - diff can detect attempts to compare a file with itself; - du has better support for hardlinked files; - cp can detect attempts to copy a file over itself.
