Replace <sys/param.h> with <limits.h> and other less dirty headers where
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)

Added rdiff support. In order to do this, some output and option fixes
had to be done for diff, too.

OK joris@

Added rannotate support

OK xsa@

Fixed cvs_findcmd I broke last time: cvs_findcmd is called during .cvsrc
parsing and must have a local cmdp variable.

> Spotted by Pierre Riteau.

Added support for rtag in local and remote setups (with interoperability
with GNU cvs). Basically we already had rtag in place as tag is supposed
to work with revisions in working directory, but our implementation was
wrong. Fixed that on the fly as well.

Simply the use of cmdp and cvs_command by zapping cvs_command and working
solely with cmdp. This remedies some reliability issues with invalid
commands supplied and also fixes a GNU cvs style incompatibility with
release command.

remove unused extern variable

ok joris@

Removed dead code.

OK joris@, ray@

Remove last bits about login and logout commands, which will never be
implemented anyway. OK ray@ niallo@.

Bring back the release command. More work to be done though.
OK joris@ niallo@.

add support for cvs rlog.
from Mickey.

ok joris@ ray@

first stab at history stuff for opencvs, currently only writes
to CVSROOT/history but cannot parse it yet with the 'history' command.

"Commit it." ray@

general includes cleanup sweep. ok joris@ niallo@

Fix const inconsistencies, void pointer artithmetic and a few other
things. now gcc -Wall and lint are more happy. ok joris@ xsa@

client-side of the annotate command is usable, build it too.

Bring back version command. Still needs tweaks to make the
gnu cvs client<->opencvs server setup work. Rest works fine.

Add server-side bits for admin command.

first part of opencvs remote, fairly useable on existing trees
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).

bring back a working version of the `cvs init' command. OK joris@.

bring back tag command; basic tag addition/deletion available. OK joris@.

add support for the export command.

export does exactly the same as checkout except it does
not create any administrative (CVS/) directories.

hello import, only works for non-existing repositories right now,
but work is in progress for importing stuff into existing repositories.

add remove support, hacked by xsa@ but lots of modifications
from me to actually make it work properly.

commiting since xsa@ is not around and i want to move forward.
ray@ agrees.

add basic 'cvs log' support.

enable basic add command, only works on files right now.

commit the new opencvs code, i have been hacking on
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.

remove a metric buttload of excessive ()
no binary change; ok ray

#include's cleanup; ok joris@ niallo@.

knf

major cleanup of the functions handling the remote cvs protocol.
makes the code a lot more readable and understandable.

ok xsa@ and niallo@

switch to xmalloc stuff, me and xsa@ agreed on this a long
time ago, but we were being held back by jfb. too bad for him.

next step is to use fatal() through out the code for unrecoverable
errors instead of trying to be all nice and fluffy and reach main() again.

ok niallo@ and xsa@

add very basic support for the following stuff:

- checkout in local mode (example: /cvs)
- update in local and server mode (example: /cvs and user@host:/cvs)
- import in local and server mode (example: /cvs and user@host:/cvs)

what remains to be done:

- not all options are supported yet, and update cannot pick up newly
added files yet. these things are pending and will be commited
real soon.

- checkout only works locally right now.

- fix rcs parsing code so that we don't fucking hog 100% cpu
on really BIG BIG BIG ass trees.

mainly tested by pedro@ and myself, thanks a lot pedro!

"go for it" niallo@

- don't check for admin files when running init;
- don't pass the Entry for newly added files to cvs_date_parse()
- in rcs_rev_add don't bother looking for the previous rev if we
are creating the RCS file.

from PR 4575

knf and spacing, ok joris@

unbreak opencvs server
ok xsa@

make sure the administrative files that the commands depend on are
present before we try to continue.

ok xsa@

move trace message before calling cvs_connect();

KNF;

rewrite of the file code. the previous one was just
a mess and not clean.
this code is much cleaner, faster, and uses less memory overall.

tested by xsa@, brad@, Michael Knudsen, and myself.
okay xsa@

<sys/param.h> is already included in "cvs.h", no need to duplicate;

don't try to run the pruning function on server side.

remove trailing whitespaces

from deraadt@

enable all commands; ok joris@.

finish pruning support, this has been sitting
in my tree since c2k5

ok xsa@

move the CVSROOT check earlier in the process, this way we get the
CVSROOT checked before the commands are run ... ok joris@.

don't forget to call cvs_disconnect() at the end
of a remote connection.

ok xsa@

handle commands which do not have any init callback a bit
better, eliminates the use of dummy functions.

OK jfb@

headers ordering (alphabetically) and cleanup, from mbalmer@ and myself;

no need to check cvs_trace before outputting a trace, the log code
does it for us

remove debugging messages

Merge the cvs_cmd and cvs_cmd_info structures and add the necessary
fields to hook local versions of the commands. This needs to go in
before it gets any bigger

ok joris

add some logging for `cvs -t' option use; ok joris@

execute the command callback at the same time we are building
the in-memory filelist. cuts down on execution time for larger trees.

"put it in!" jfb@

first part of file API changes:

- fix our behaviour regarding directories or files in a different
directory than we currently are as arguments to commands, this
allows stuff like "cvs status sys/arch/i386/Makefile" to work.

- when parsing a pathname only load the needed nodes of the path
instead of loading *everything* in memory.

the next step in this is to merge the collection and callback
execution together.

ok jfb@, xsa@

* add missing 'R' flag in diff synopsis
* add the CVS_EX_BADROOT return code to indicate that there was no
CVSROOT given or it was invalid

ok joris, xsa

remove debugging leftovers

Modify the CVSFILE structure using a union to keep information about
both files and directories. We can now keep the revision number for
regular files, and don't need to fetch the appropriate entry in the
command callbacks. This saves a huge amount of parsing on Entries
files.

ok joris@

cmd_helper() returns error codes > 0 or 0 on success.

use the new CVS_EX_* error codes here as well.

introduce our own set of error codes used by the commands to report
what exactly went wrong in case of an error.

ok jfb@

don't include sysexits.h now we don't use those error codes
anymore.

remove EX_USAGE error codes

ok jfb@

first round of EX_* exit codes removal; ok joris@.

make sure we don't do unneeded things for the version command.

make sure the server command can still be reached with the
new framework.

ok xsa@

- as long as we are using the sysexits.h error codes make sure
we handle them.
- handle cmd_sendflags() when it fails.

allow cmd_options to be NULL, so that commands which
have no options will work fine.

fix argument count in cvs_startcmd()

ok jfb@

add the first pieces of our new command framework.

ok jfb@
