* When system calls indicate an error they return -1, not some arbitraryderaadt2019-06-281-4/+4
| | | | | | value < 0. errno is only updated in this case. Change all (most?) callers of syscalls to follow this better, and let's see if this strictness helps us in the future.

| | | | | | | | | possible. Annotate <sys/param.h> lines with their current reasons. Switch to PATH_MAX, NGROUPS_MAX, HOST_NAME_MAX+1, LOGIN_NAME_MAX, etc. Change MIN() and MAX() to local definitions of MINIMUM() and MAXIMUM() where sensible to avoid pulling in the pollution. These are the files confirmed through binary verification. ok guenther, millert, doug (helped with the verification protocol)

* Switch rcsdiff(1) binary file detection from !(isprint() || isspace()) tostsp2013-05-161-6/+3
| | | | | | | checking for embedded NULs, as was done for grep(1) and diff(1) some time ago. Avoids problems with e.g. latin1-encoded files being treated as binary, since isprint() uses only ASCII by default and rcsdiff(1) doesn't call setlocale(). ok sthen

* Sync with diff/diffreg.c r1.75:ray2010-07-151-5/+4
| | | | | | | Return -1 on error as advertised. Handle case when only one stream failed. OK xsa, stsp
* More cvs/diff/rcs convergence:ray2009-06-071-4/+2
| | | | | | | | | | | 1. Mostly variable/function renaming, SIZE_T_MAX->SIZE_MAX, and spacing. 2. One strchr -> strncspn. 3. diff had a weird thing where it set file[12] = ofile[12] but never updated file or ofile, then if file and ofile were different it freed it. I removed it. OK millert

* diff(1) sync, mostly spacing and moving crap around, except:ray2007-06-281-51/+46
| | | | | | | - stone() and newcand() cannot return < 0, so don't check it. - \r, \v, \f are also whitespace OK joris
* Some syncs with diff(1):ray2007-06-281-32/+28
| | | | | | | | | | - prepare() only returns 0, so change it to void and remove code that checks its return value. - Rename diff_len[] to len[]. - Remove casts that made the code a no-op: (size_t)filesize <= SIZE_MAX OK xsa

* Since xrealloc dies on failure it is safe to directly assign to theray2007-05-291-22/+11
| | | | | | | | | original pointer. Theo agrees, and so does the rest of the tree (ssh, etc. all do this already). Saves a bunch of variables and assignments. OK niallo@

| | | | | | | | | | | | | | from src/usr.bin/diff/diffreg.c rev 1.67: improve -p for C++ code: classes definition often have public:/protected:/private: at the start of line. This lets the -p scanner just take note of the section and keep looking for the actual class definition. Also increase function name bufsize so it shows most of these pesky C++ decls... OK niallo@ espie@.
* As done in OpenCVS, general includes cleanup sweep. OK otto@.xsa2007-02-271-2/+12

* Fix const inconsistencies, void pointer artithmetic;xsa2007-02-221-2/+3
| | | | Based on diff from otto@ in OpenCVS. OK otto@.
* Plug memory leak.ray2006-09-271-1/+2
| | | | OK niallo@.
* Add support to rcsdiff for all the other diff flags thatmillert2006-09-211-89/+89
| | | | | are pertinent to files (not directories) and that do not conflict with rcsdiff-specific flags. OK xsa@
* files_differ() should return -1 on error, according to comments. Makeray2006-08-141-3/+12

* Remove (size_t) casts on integer constants.ray2006-05-101-6/+6
| | | | | | | We should not cover up lint's shortcomings, especially if they no longer exist. ``This is definately good.'' niallo@.
* - fix rcsdiff exit status on success/errors; now matches gnu/usr.bin/rcs.xsa2006-05-051-2/+2
| | | | | - add DIAGNOSTICS section to rcsdiff.1 wrt exit codes. ok ray@ and jmc@ for man page bits.
* Check return values for all strlcpy, and strlcat calls.ray2006-04-291-3/+4

* fork our code we shared between openrcs/cvs into the openrcs dir.joris2006-04-261-0/+1394
this was starting to become inhuman to maintain without ugly ugly hacks in the shared code, and it will be easier to make specific changes for openrcs without touching the soon-to-be-replaced opencvs code.
