2018-07-27hush: in some cases, expand_on_ifs() relied of uninitialized memoryDenys Vlasenko
The n > 0 check to prevent access to the last byte of non-existing argv[-1] wasn't enough. Switched to making sure there are initialized (zero) bytes there. A predictable testcase is rather hard to construct, unfortunately, contents of memory depends on allocator behavior and whatnot. function old new delta o_save_ptr_helper 119 137 +18 expand_on_ifs 345 339 -6 ------------------------------------------------------------------------------ (add/remove: 0/0 grow/shrink: 1/1 up/down: 18/-6) Total: 12 bytes Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>

2018-07-25htpd: increase MIN_FREQHOLD by 3Denys Vlasenko
This means we'll start correcting frequency ~5 minutes after start, not ~3.5 ones. With previos settings I still often see largish ~0.7s initial offsets only about 1/2 corrected before frequency correction kicks in, resulting in ~200ppm "correction" which is then slowly undone.

2018-07-24hush: fix nested redirects colliding with script fdsDenys Vlasenko
This necessitates switch from libc FILE api to a simple homegrown replacement. The change which fixes the bug here is the deleting of restore_redirected_FILEs(); line. It was prematurely moving (restoring) script fd#3. The fix is: we don't even _want_ to restore scrit fds, we are perfectly fine with them being moved. The only reason we tried to restore them is that FILE api did not allow moving of FILE->fd. function old new delta refill_HFILE_and_getc - 93 +93 hfopen - 90 +90 hfclose - 66 +66 pseudo_exec_argv 591 597 +6 hush_main 1089 1095 +6 builtin_source 209 214 +5 save_fd_on_redirect 197 200 +3 setup_redirects 320 321 +1 fgetc_interactive 235 236 +1 i_peek_and_eat_bkslash_nl 99 97 -2 expand_vars_to_list 1103 1100 -3 restore_redirects 99 52 -47 fclose_and_forget 57 - -57 remember_FILE 63 - -63 ------------------------------------------------------------------------------ (add/remove: 3/2 grow/shrink: 6/3 up/down: 271/-172) Total: 99 bytes Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>

2018-07-23hexedit: fixes for redraw and down movement causing SEGV on attempt to accessDenys Vlasenko
"Go to:" command was not updating row position, making next "down" movements for one screenful print empty lines instead of showing the contents. If the file is whole pages long, "down" movement at EOF was advancing position +16 bytes, mapping the next portion (entirely past the end of the file), then finding out that the new position is beyond the EOF, rolling it back -16 bytes... ending up with this postion pointing *before* the mapped portion. Any next access (e.g. "move right" key) SEGVs. function old new delta hexedit_main 1170 1184 +14 Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>
