"subversion" for the Amiga ========================== 1. Introduction This is a port of "subversion" (version 1.1.4) for the Amiga, using GCC and my clib2 runtime library. "subversion" is a revision control system, such as the older "RCS" and "CVS". It does offer much more than these older systems, see for yourself at <http://subversion.tigris.org>. I have included some of the documentation that was part of the original distribution archive in the "doc" directory, but I recommend that you have a look at the web site. 2. Installation I built binaries both for the 68k platform and OS4. You need an Amiga with 68020 CPU/Kickstart 2.04 or better. Or, of course, an Amiga with AmigaOS4. If you want to access "subversion" repositories on SSL servers you will need to have AmiSSL V3 or better installed. I have made a few small changes to fit the client software (svn, etc.) better into the Amiga framework. These are as follows: - The place where global subversion configuration files are searched for in is "subversion:". On Unix, that would have been "/etc/subversion". - The "svn" command uses a lot of stack space. I measured about 180K as the minimum and pre-configured "svn" to use 200K just to be sure. But you can override the stack size through an environment variable, like this: setenv SVN_STACK_SIZE 500000 All other commands also check the SVN_STACK_SIZE environment variable to set the default stack size; they all start with a minimum of 20000 bytes. - All programs bear the typical Amiga version strings. - I have added new auto-props by the names of "amiga:protection" and "amiga:comment". These specifically store the Amiga typical file and directory protection bits and the comment strings associated with them, respectively. If you want to use these features, don't forget to put the following line into your "subversion:config" file: auto-props=yes Checking files in and out will then have their Amiga specific protection bits and comments recorded and restored. Please note that all the tools still "believe" that they are running in a Unix environment. This means that path names for files and directories are following the Unix rules. For example "." is the name of the current directory, ".." the name of the parent directory and absolute path names, such as "/Work/foo/bar", stand for "Work:foo/bar". 3. SSL support In order to access repositories stored on SSL servers you will need to have AmiSSL V3 or better installed. Older versions do not work, and neither does the "Miami Deluxe" SSL support library. If the required AmiSSL software is not installed, the "svn" and "svnversion" clients will pretend that they do not support SSL server access; no specific error message to detail this will be printed. 4. SSH support Starting with version 1.7 this subversion 1.1.4 port supports the svn+ssh:// access method for repositories using a built-in SSHv1 client. This means that the remote repository has to support the by now rather obsolete version 1 of the SSH protocol, which is not necessarily the case today. Ask your administrator... By default the SSHv1 client will connect to port 22 on the remote server. You can override this by creating a file "subversion:sshconfig" which contains server specific configuration options. Such a file could look as follows: host foo.bar.com port 22001 cipher blowfish user barney password secret host foo.bar.com port 22001 cipher blowfish user fred password 12345 host 192.168.0.107 cipher 3des user fred password secret Each configuration section starts with a host name, or an IPv4 address. This is followed by a port number, a choice of cipher and optional login information. If you omit the port number, the default of 22 will be used. If you omit the cipher name (which can be one of either "blowfish" or "3des"), a default of "3des" will be used. For security reasons you should not include the login information in this configuration file, but, well, if you want to, you can. For the password to be picked up, the respective options have to include the matching server name and the matching user name. If no password is provided in the options file, the SSHv1 client will prompt you to enter it on the command line. 5. Caveats This port is largely untested. I did try to check out and update repositories and I verified how much stack space the client programs use. They did work fine for me, but your mileage may vary. I do not know if the "svnserve" program actually does what it's supposed to do, so you better be careful. 6. Source code I have included the source code changes I made in the "source" directory. To build the "subversion" programs from it, just download the "subversion-1.1.4.tar.gz" archive from <http://subversion.tigris.org>, unpack it and copy the contents of the "source" directory on top of it. I have provided a copy of zlib which integrates into the build. You also need a copy of the bsdsocket.library SDK header files (e.g. from the "Roadshow" SDK) which must be copied into the local "netinclude" directory. To build with SSL support, you will need the AmiSSL V3 SDK, whose contents must be copied into a directory called "amissl". With all these in place, invoke either "make -f GNUmakefile.68k" or "make -f GNUmakefile.os4", respectively, and wait. Note that you need GNU make for this to work, and of course my clib2 'C' runtime library which you can find on <http://sf.net/projects/clib2>. 7. Contact information You can contact me here: e-mail: obarthel()gmx.net Snail mail: Olaf Barthel Gneisenaustr. 43 D-31275 Lehrte Federal Republic of Germany If you appreciate the amount of work I spent on making this software available, please let me know. A contribution through my PayPal account "o.barthel()logical-line.de" would be most appreciated! 8. Recent changes Amiga Port 1.7 (23.4.2009) - Added ssh support. It only took two years to write this... Amiga Port 1.6 (21.4.2009) <cmincea> - !!! ONLY FOR AMIGAOS4 POWERPC !!! Only the AmigaOS4 executables are updated! The 68k executables were not updated simply because it didn't compile with my quickly set up m68k crosscompiler.. if somebody thinks 68k binaries are absolutely needed, feel free to compile and add them to this archive. Otherwise use the 1.5 68k binaries. - Activated the callback functions for prompting the user if he wants to accept a self-signed SSL server certificate or not. Now it's finally possible to connect to such servers, before svn just exited with an error message. - Corrected USR and SYS path defines for the AmigaOS version. Everything is now stored in subversion: so make sure you have that assign. With this change our subversion port finally is able to remember login details for certain servers. You can deactivate this with store-passwords=no in the [auth] section of subversion:config - Recompiled with latest clib2 1.204 Amiga Port 1.5 (25.2.2006) - SSL support now actually works and require AmiSSL V3 or better. Thanks go to Andrija Antonijevic for helping me to make the SSL code build and work correctly. Amiga Port 1.4 (24.2.2006) - The "svn" client now pretends that every directory checked in is readable, writable and accessible. This should have the effect of making a checkout on Unix system usable again, which would have otherwise made directory access more difficult. - Added experimental SSL support. - Rebuilt with most recent clib2 1.198 release. Amiga Port 1.3 (12.11.2005) - The "amiga:comment" and "amiga:protection" auto-props now also have and effect if the names of the files and directories concerned contain absolute paths, e.g. "Work:foo/bar". Previously, only relative path names were supported. - Removal of the "amiga:comment" and "amiga:protection" properties no longer throws Enforcer hits. For "amiga:comment" empty property data will be translated into an empty comment string. An empty "amiga:protection" property will be ignored altogether. - Incomplete or invalid "amiga:protection" properties will be ignored. You can, however, choose to omit the group and world protection information from the "amiga:protection" property and retain only the owner/special protection information. For example, "----rwed" is considered valid protection information, and so is "rwed" (both stand for the owner/special protection bits). - Rebuilt with most recent clib2 1.197 release. Amiga Port 1.2 (28.4.2005) - Initial public release, as uploaded to Aminet.
