Hello, I'm doing some work to make cvs-nserver full OpenBSD compliant :-) Basically there are three things to do to successfully build cvs-nserver on OpenBSD: 1) Cut out the line below from src/server.c : #define _POSIX_SOURCE 1 (server.c includes <sys/socket.h> which has some non posix declarations, and also uses FD_SETSIZE which is declared in sys/types.h only when _POSIX_SOURCE is not declared) 2) Install gnu-m4 which is not supported by OpenBSD (gnu m4 is not even present in to the ports tree of release 3.0). It seems that OpenBSD's m4 can substitute gnu m4 in almost every situation , but the following autoconf rule which checks for gnu m4 fails: AC_PROG_GNU_M4 (it fails checking for frozen files support) 3) Compile with GNU Make. Now, point (1) is a suggestion to patch source code. Point (3) is no problem. About point (2) is not clear to me if the AC_PROG_GNU_M4 rule was inserted in configure.in by some automatic tool like autoscan or was manually inserted by cvs-nserver coders , and why it was inserted. Do you think it is strictly needed ? Also in the next days I hope to send you patches to integrate OpenBSD changes made to cvs into cvs-nserver. Actually I have made a single patch yet and I tested it. But I want to separate it in single patches for each bugfix/feature made by the OpenBSD team, before submitting them to you.

Although, > sure, if you think that those patches are needed for nserver -- I agree. My impression is that cvs development is too slow, and that they are reclutant to add patches/improvements. Wasn't this one of the reasons the cvs-nserver project was started ? For example look at: http://www.cvshome.org/cyclic/cvs/dev-keywords.txt The improvement to add an optional custom "Id"-like RCS identifier was proposed years ago. It is used by *BSD guys since years. Right in the link above you can read that development team judged it a good thing, but nothing has been done. Also I'm not the original author of these improvements, and my guess is that patches have been sent to cvs/Cyclic by OpenBSD team , as this is the usual behaviour when making ports. I like the idea of cvs-nserver, and I think it can be improved and may be it could be distributed with OpenBSD in the future. The network code rewriting and the ssl support could be two major points for it to be approved by OpenBSD [note that I'm not currently connected in any way to the OpenBSD team, so these are my guesses] .

Here are the patches taken from modifications of OpenBSD team to cvs. All code was taken from OpenBSD except for two lines of code that I added to make the new "-t" option work also in pserver mode. Explantions follow: fixes.patch: Minor fixes/improvements localid.patch: This patch allows to specify a custom RCS identifier string to be used like the "Id" identifier. It can be specified by command line on checkout/update/export or in CVSROOT/config file. The explanation in the new manpage is: ------------------------------------------------------------------------------ -t id Expand the RCS identifier specified by the id argument in addi- tion to the default ``Id'' identifier. -t is available with the checkout, export, and update commands. If the identifier name is specified as ``-'', no additional identifiers will be expanded. ------------------------------------------------------------------------------ readonly.patch: Allows to set the cvs repository as readonly using the new "-R" global option. newhostname.patch: permit [] hostname formats in CVSROOT, for IPv6. config.patch: Allows to force cvs umask and resource limits from CVSROOT/config file.

Hmm, well we really need the proper logging facility. BTW, Alex, did you consider smth I call multilevel logging as it's done in repcheck utility? I.e. when server logs every little step it does but w/ different logging level. At first look there could be 'fatal', 'security', 'normal', 'debug' levels and there would be a filter that specify how much information should go into logs.
