* patch: Bring in xstrdup and use it when appropriate.Pedro F. Giffuni2014-12-254-18/+35
| | | | | | | | | | | | | | | The function savestr allows NULL return values during Plan A patching so in case of out of memory conditions, Plan B can step in. In many cases, NULL value is not properly handled, so use xstrdup here (it's outside Plan A/B patching, which means that even Plan B relies on successful operations).

Also fixes an out of boundary memory access because the resulting values are used as array indices.

| | | | | | | | | | | | | Other implementations of patch(1), including GNU patch and "svn patch" have a --dry-run option which does the same as our -C or --check option. Add a new alias to make our implementation more compatible. MFC after: 1 week Notes: svn path=/head/; revision=267512
* patch: unsign the line length to avoid overflows.Pedro F. Giffuni2014-06-153-11/+15
| | | | | | | | | | | | | | | | | | Patch(1) uses a short int for the line length, which is usually sufficient for regular diffs, but makes no effort to signal when there is an overflow. Change the line length to an unsigned short int to better use the fact that a length is never negative. The change is loosely inspired on a related change in DragonFly, but we avoid spending more memory than necessary. While here adjust the messages to be clearer on what is happening.

| | | | | | | | | | | As promised, drop the option to make the older GNU patch the default. GNU patch is still being built but something drastic may happen to it to it before Release. Notes: svn path=/head/; revision=255014
* Make the BSD-licensed patch the default.Pedro F. Giffuni2013-07-261-3/+3
| | | | | | | | | | | | | | | | | | The BSD-licensed patch(1) command has matured and it's behaviour can be considered equivalent to the older version of GNU patch in the tree. The switch has been extensively tested [1] and only two ports presented regressions, which have since been fixed. For convenience a new WITH_GNU_PATCH option is available, but it will likely be removed in the near future. PR: 176313 Approved by: portmgr Notes: svn path=/head/; revision=253689

* Merge r252513 from src/gnu/usr.bin/patch into src/usr.bin/patch:David E. O'Brien2013-07-031-1/+1
| | | | | | | | | | | Properly handle input lines containing NUL characters such that pgets() accurately fills the read buffer. Callers of pgets() still mis-process the buffer contents if the read line contains NUL characters, but this at least makes pgets() accurate. Notes: svn path=/head/; revision=252637
* Merge r252512 from src/gnu/usr.bin/patch into src/usr.bin/patch:David E. O'Brien2013-07-031-2/+6
| | | | | | | | | | | | Make it so that 'patch < FUBAR' and 'patch -i FUBAR' operate the same. The former makes a copy of stdin, but was not accurately putting the content of stdin into a temp file. This lead to the undercounting the number of lines in hunks containing NUL characters when reading from stdin. Thus resulting in "unexpected end of file in patch" errors.

* Fix target selection logic, which did not comply with the man page.Stefan Eßer2013-05-231-2/+8
| | | | | | | | | | | | | | | | | | | Instead of using the file with the least order of path name components, shortest filename and finally the shortest basename (with the search stopping as soon as one of these conditions is true), the first filename checked was used as the reference, and another filename was only selected if all of the above comparisons are in favour of the latter file. This was wrong, because filenames with path less components were only considered, if both of the other conditions were true as well. In fact, the first filename to be checked had good chances to be selected in the end, since it only needed to be better with regard to any one of the three criteria ...

| | | | | | | | | | | | According to the README file [1] the 12u variant, unlike the 12g variant, contains no copyleft code. It is therefore convenient to keep using the original versioning scheme to prevent confusions.
