* Fix one serious bug and one potential problem with in-place editing code:sobomax2002-06-141-70/+60
| | | | | | | | | | | | | - original version of code worked incorrectly when more than one input files were specified - it was moving the last line from the 1st file to be the first line of the 2nd, last line of the 2nd to be the first line of the 3rd and so on; - use mmap()->write() to create temporary file instead of malloc()->read()->write(), which was not only slower, but also did not bother to free allocated memory once backup file was created, potentially leading to memory exhausting when regex is applied to a big file or a large number of small ones.

* Add a -i option to sed(1) to do inplace editing, to give us an alternative tojmallett2002-05-072-3/+77
| | | | | | | | | | | | | | | | | | Perl for such things. The key difference to Perl is that a backup extension *MUST* be specified, because on one hand it isn't recommended to have options which optionally take a parameter, and on the other hand, it'd be slightly unpleasent to implement proper handling for that. The difference between this and the version posted to developers@ is that it does handle multiple files in argv after the getopt(3) handling "correctly", in that the inplace editing-specific code has been moved out to a function, and that function is used beyond the first file in our linked list. This option has been documented as FreeBSD-specific in the manpage. Reviewed by: developers@ (got feedback from: des, fanf, sobomax, roberto, obrien) MFC after: 1 week

| | | | | | | | | | | | | | | | | 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 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. Submitted by: Tim J.
