However, I've ran into a couple of problems with them: * it looks like `git-cvsimport' uses its own CVS protocol implementation which doesn't support compression; I've tried to clone a repository of a project hosted in CVS since circa 1998 and it 20 MiB or so to obtain revisions until 2000 or so; any ways to minimize traffic? * how many revisions will `git-svn fetch' obtain from the SVN repository? I had to run it for several times to get the full history; I've tried to use (undocumented) `--fetch-all' option, but it appears to help (may be but for a little.) BTW, does http://.../git.git/ mean a ``bare repository (i. e., a would be /git/.git/) for Git''? PS. I wonder, if this mailing list accepts mail from unsubscribed `From:'s? ``` ## Michael Poole, 2007-11-09 16:37 Subject: Re: tracking remotes with Git Message-ID: <87ode31iki.fsf@graviton.dyn.troilus.org> URL: https://gitlist.dev/e/87ode31iki.fsf%40graviton.dyn.troilus.org In-Reply-To: ``` Ivan Shmakov writes: > I'm using Git (1.5.3.5 debian 1) for about a day or so, and I'm > quite impressed that it allows tracking remote repositories > (I've tried CVS and SVN) so easily with `git-cvsimport' and > `git-svn'.

What I do is arguably a horrible kludge, but it works well: rsync to mirror the CVS repository to my local drive, and cvsimport from that. When I was tweaking the import process (command-line options and the author conversion file), having the local copy helped a lot.

Well, rsync certainly gives CVS the ``disconnected operation'' ability... Any chances to get rsync (or scp/sftp, etc.) access to the CVS repositories on Savannah? (I'm not one of the developers of the aforementioned project, if that matters.) ``` ## Robin Rosenberg, 2007-11-09 20:38 Subject: Re: tracking remotes with Git Message-ID: <200711092138.56277.robin.rosenberg.lists@dewire.com> URL: https://gitlist.dev/e/200711092138.56277.robin.rosenberg.lists%40dewire.com In-Reply-To: ``` fredag 09 november 2007 skrev Ivan Shmakov: > I'm using Git (1.5.3.5 debian 1) for about a day or so, and I'm > quite impressed that it allows tracking remote repositories > (I've tried CVS and SVN) so easily with `git-cvsimport' and > `git-svn'.

You can pass options to cvsps. My guess is -P "-Z" will do it. -- robin ``` ## Ivan Shmakov, 2007-11-11 04:05 Subject: Re: tracking remotes with Git Message-ID: URL: https://gitlist.dev/e/m24pftmnpi.fsf%40cherry.siamics.int In-Reply-To: <200711092138.56277.robin.rosenberg.lists@dewire.com> ``` >>>>> Robin Rosenberg writes: [...] >> * it looks like `git-cvsimport' uses its own CVS protocol >> implementation which doesn't support compression; I've tried to >> clone a repository of a project hosted in CVS since circa 1998 and >> it 20 MiB or so to obtain revisions until 2000 or so; any ways to >> minimize traffic? > You can pass options to cvsps. My guess is -P "-Z" will do it. Well, this helps somewhat. But still, IIUC, cvsps(1) is used only to reconstruct the ``patch sets'', and to fetch the actual revisions, `git-cvsimport' contacts the CVS repository directly: --cut: $ nl -ba git-cvsimport-- ... 182 package CVSconn; 183 # Basic CVS dialog. 184 # We're only interested in connecting and downloading, so ... 185 ... not a word about the compression... 482 package main; 483 484 my $cvs = CVSconn->new($opt_d, $cvs_tree); ... 911 print "Fetching $fn v $rev\n" if $opt_v; 912 my ($tmpname, $size) = $cvs->file($fn,$rev); ... 930 unlink($tmpname); ... --cut: $ nl -ba git-cvsimport-- ``` ## Ivan Shmakov, 2007-11-14 18:26 Subject: Re: tracking remotes with Git Message-ID: URL: https://gitlist.dev/e/m2r6isiszg.fsf%40cherry.siamics.int In-Reply-To: ``` >>>>> "IS" == Ivan Shmakov writes: [...] IS> * it looks like `git-cvsimport' uses its own CVS protocol IS> implementation which doesn't support compression; I've tried to IS> clone a repository of a project hosted in CVS since circa 1998 and IS> it 20 MiB or so to obtain revisions until 2000 or so; any ways to IS> minimize traffic?
