2021-07-12ash: tidy code, no functional changeRon Yorston1-24/+14
If we know fs_size is nonzero there's no point in having SAVE_PTR2 and SAVE_PTR3 macros. The code is slightly tidier if we only use SAVE_PTR.

ptest() was using this idea already. As far as I can see, this is safe. Ttestsuite passes.

It seems to be designed to reduce overhead of malloc's auxiliary data, by allocating at least 64 variables as a block. With "struct var" being about 20-32 bytes long (32/64 bits), malloc overhead for one temporary indeed is high, ~33% more memory used than needed. function old new delta evaluate 3137 3145 +8 modprobe_main 798 803 +5 exec_builtin 1414 1419 +5 awk_printf 476 481 +5 as_regex 132 137 +5 EMSG_INTERNAL_ERROR 15 - -15 nvfree 169 116 -53 nvalloc 145 - -145 ------------------------------------------------------------------------------ (add/remove: 0/2 grow/shrink: 5/1 up/down: 28/-213) Total: -185 bytes Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>

2021-06-27win32: changes to mntent implementationRon Yorston3-64/+77
Make the structure returned by getmntent(3) static so it persists after endmntent(3) closes the stream. No current caller in the WIN32 port needs this functionality but it's good to match the documented behaviour. Populate more fields of the mntent structure in find_mount_point(). This is required to support the df -t and -T flags recently added upstream. The static structures used here are allocated on demand. Separate static structures are used in each case because df iterates through mounts calling statfs(2) on each and the WIN32 implementation of statfs(2) calls find_mount_point().
2021-06-27vi: stored search pattern applies to ':s'Ron Yorston1-0/+12
The same stored search pattern applies to both search ('/') and search/replace (':s') operations. A search/replace operation with an empty "find" string (':s//abc/') should use the last stored search pattern, if available, and issue an error message if there is none. If the "find" string is not empty it should replace the stored search pattern. function old new delta colon 3952 4024 +72 ------------------------------------------------------------------------------ (add/remove: 0/0 grow/shrink: 1/0 up/down: 72/0) Total: 72 bytes Signed-off-by: Ron Yorston <rmy@pobox.com> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>
