* When system calls indicate an error they return -1, not some arbitraryderaadt2019-06-281-6/+6
| | | | | | 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.
* Quiet compiler warnings. OK tomc@ tb@millert2016-10-151-3/+3

| | | | | | | | | 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)

* Support -U and -C to specify the context length for "cvs diff".nicm2010-07-281-12/+12

* More cvs/diff/rcs convergence:ray2009-06-071-13/+9
| | | | | | | | | | | 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

* Sync rcsdiff -> cvs diffray2007-05-301-12/+14
| | | | | | | | | | | Surprisingly, rcsdiff has nicer code than cvs diff. Changes: 1. Include sys/param.h because we are using MIN/MAX... not sure why it hasn't complained in the past. 2. Use fstat instead of stat. 3. Remove useless casts and __inline. 4. Plug a memory leak. 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@.

* first part of opencvs remote, fairly useable on existing treesjoris2006-07-071-3/+3
| | | | | | | | | | | | | | although i advise against using it on real development trees for now. only a few commands work right so far: - commit - diff - status - log - update (partially working) if you feel like testing remote and run into bugs feel free to contact me, and please include a full trace (-t).

* commit the new opencvs code, i have been hacking onjoris2006-05-271-0/+1393
this for the past 2 weeks now and it should go in at the start of the hackathon so others can help out. this code is a lot safer, smarter, faster and best of all it is actually doing what it is suppose to do! basic checkout, update, status, diff and commit are working in local mode only. there is no support for any remote setups now.
