No. I got it. It will corrupt my files in the default configuration after instalation, until I tell it that .gif files are not text Correct. The present incarnation of cvs does not know that a particular file should be treated as a 'binary' just because the file name happens to match the pattern that some folks use for Graphical Interchange Format. I suppose we could collect the cvswrappers provided as a hint into the contrib directory... If someone wanted to hack in an automagical recognition system that could be enabled for binary file types, I suppose we could consider adding it. However, care would need to be taken that files that happened to be in I8N international character sets were handled properly too... svn, monotone, gnu arch and others have all arisen more recently than cvs and try in various ways to address the legacy problems that cvs continues to have. I think there are some binary diff algorithms... Indeed. Consider svn which uses xdelta internally. To be fair, CvsNt also has ways of dealing better with binary formats than the cvshome version. There is a hope that we can move toward merging the feature sets between those two major varitions of cvs over time, but it will likely take a bit of time as no one is being funded full time to work on just cvs development. So I see there are many alternatives available, but cvs has not changed. No, cvs has changed a great deal. There was a time when it had significant problems with binary data. Now, once you tell it that it should treat it as binary, it mostly does the right thing (as has been mentioned, it probably should have the ability to plug in a series of merge programs other than diff3 to handle binary data better). It is also true that cvs lacks a full time advocate for change in this direction. Most of the advocates of major changes have left the cvs project to work on a redesign called subversion. The current cvs has many problems that are not yet addressed: - renaming files - versioning directories - dealing with symbolic links - better branching models - alternatives to diff3 for non-text files or structured text files (a la XML and HTML) where diff3 does not work well. - better access control models There are a lot of others as well, just look at the TODO file in the top-of-tree ccvs/TODO file some time. Looks like developers want to offer their new products and not to support the original cvs :( Very sad to find out about this This is so strange and such a bad thing ... It is not clear to me that incremental improvement to cvs will necessarily solve some of the major perceived flaws. I'd love to see more detailed plans on how to add improvements to cvs in a controlled way that lets everyone come along for the ride without lots of flag days taking place. However, that requires real work and commitment and a vision of what problems need to be solved. The design itself does not needs litte changes. cvs design can perfectly acomodate binary sources. It just has to be done (or implemented). Should I look forward to seeing your patches to help out on the project? They would be looked at with favor by all of your fellow cvs users. Well I write PHP now. I think there's a long way from web pages to a serious public application Okay. I hope I'll study xdelta in the near future It is an interesting topic. -- Mark -BEGIN PGP SIGNATURE- Version: GnuPG v1.2.3 (FreeBSD) iD8DBQFAwrgY3x41pRYZE/gRArvxAJ9GIKVZ+E5SRUSswFlE+tdtnZXsUwCdErq+ C7A9YQeEwaDmJ5AC3wQ+Gwc= =zrsI -END PGP SIGNATURE- ___ Info-cvs mailing list [EMAIL PROTECTED] http://lists.gnu.org/mailman/listinfo/info-cvs

Re: reports
Hi, I think that Perl LibCVS (http://libcvs.cvshome.org) can help
you out with this. Some Perl code would have to be written to
format the information the way that you want, but it provides
access to the stuff that you need.
I can help you with this code, I think that it might be more
broadly useful. The released version on the site and CPAN is
getting a bit old, I'm going to make a new release soon, but the
HEAD version should pretty much do what you want.

Ramanuj How cvsgraph/cvsweb extract tags and branches from repository. I
Ramanuj have gone through their codes but I m harldly able to get some
Ramanuj information about the extraction of tags and branches. Or give me a
Ramanuj script which gives information about all the tags and branches along
Ramanuj with the date of creation and name of author. This is really urgent
Ramanuj as I m new in CVS and working as cvs administrator. Don't tell me
Ramanuj about the history command as it generates reports only for the tags
Ramanuj created with rtag command.
Ramanuj Even CVSWeb also gives the graphical view of branch and tag. If u
Ramanuj can help me in this scenario , I will be grateful to u. Have to
Ramanuj generate this kind of report on urgent basis.
Ramanuj I need the kind of report as history command generates for all
Ramanuj tags. As I have mentioned earlier the history command is not of
Ramanuj great help as generates report about the tags or branches created by
Ramanuj rtag command. So the tags created by simple tag command are not
Ramanuj mentioned in this repor
Ramanuj I need to generate report from cvs reporsitory for a project which
Ramanuj displays the fields as I mentioned before. Don't need to just look
Ramanuj up in wincvs and get information. I have to generate report from cvs
Ramanuj repository. Not have to manually see those information and pen it
Ramanuj down. May be a script can do. There are many projects in our
Ramanuj repository and for each project looking at the graphical view and
Ramanuj penning down the information is not the stuff we have to do. I have
Ramanuj to submit the reports about the tags and branches on Monday. I m cvs
Ramanuj newbee. So its really urgent.
Ramanuj The format for the report which will do is as follows,
Ramanuj Date Name of tag or branch Name of the author
Ramanuj Right now have to generate report for the project of duration of
Ramanuj three months from march to may, on weekly basis

This way, you cannot miss the binary files. Actually, that was suggested 3 years ago as well. It turns out to be a very good one. However, while there are fewer standard file extensions that are text, many ad-hoc files (non-standard extensions) are almost allways text. Hence, it's easier to predict binary extensions that it is text extensions ! A suggestion 3 years ago was to run the file command on newly added files to determine it's format. That practice would solve your issue I presume. While you may be right about .doc or .au files, in practice, I have found that this has worked remarkably well. Over the course of 3 years, I have never had anyone complain about files that CVS broke. Almost all binary files added to CVS are - compressed source distros, prebuilt binaries, images, sound samples and open/win32 office files.

It's true that a general purpose file type identifier is not possible, it is possible to get arbitrarily close to 100% accuracy on a per-shop basis. Also, relying on file extensions alone is notoriously inaccurate. A mechanism like the Unix file(1) command that examines a file's content is much better. And then the configuration of it really needs to be in the CVS admin's face from the start. --- End of forwarded message from [EMAIL PROTECTED] ___ Info-cvs mailing list [EMAIL PROTECTED] http://lists.gnu.org/mailman/listinfo/info-cvs
