2011-09-17Rewrite the main loop of the "sed s/..." command, to fix multipleIngo Schwarze
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.
2011-07-26Backout previous, naddy@ found the following regression:Ingo Schwarze
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.
2011-07-24Rewrite the main loop of the "sed s/..." command, shortening it by tenIngo Schwarze
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@.

Now that we have dynamically sized buffers there may not be room for the NUL until after realloc.
