* Rewrite the main loop of the "sed s/..." command, to fix multipleschwarze2011-09-171-49/+44
| | | | | | | | | | | | | issues regarding the replacement of zero-length strings. This commit brings back rev. 1.16, but without the regression that forced the backout: No NUL bytes will be output now, not even when the input file lacks a trailing newline character and there is a zero-length match at the end. OK otto@ deraadt@; and naddy@ (who originally found the regression) checked that the regression is indeed fixed.
* Backout previous, naddy@ found the following regression:schwarze2011-07-261-43/+49
| | | | | | | | When the input does not end in a trailing newline character and there is an empty match at the end, the new code adds a spurious '\0' character. I have a fix, but otto@ prefers backout and full re-evaluation after release.
* Rewrite the main loop of the "sed s/..." command, shortening it by tenschwarze2011-07-241-49/+43
| | | | | | | | | | | | | | | lines and simplifying it by removing the switch statement implementing /g, /1, and /2 separately and repetitively. The idea to make the loop control variable slen, i.e. the length of the string remaining to be processed, signed, and stay in the loop even when slen == 0 (i.e. at the end of the string), lifted from FreeBSD by otto@. On i386, process.o shrinks by 440 bytes, and the sed binary by 23 bytes. This fixes multiple aspects of the replacement of multiple (/g) or specific (e.g. /2) instances of zero-length matches, both with BREs and EREs, both with and without a trailing newline character on the input. Feedback and OK otto@.

| | | | | | | | | | | | | | | is not specified, and then the first part of the pattern space is deleted, when there are two or more input lines, as this results in subtraction of one from an unsigned integral value of '0'. That bogus value is used in one case for a loop (that will run far too many times in this case) and a function to search for a value within a specified range of memory, however now the range of memory is obscenely large and a segmentation (or memory) fault will occur. This is fixed by checking for and appropriately handling a nil pattern space as if the specified search in memory failed, as indeed it obviously will with nil pattern space. From Tim J. Robbins by way of FreeBSD
