SymDiffParent in cvs2svn 0.51
When trying to import my whole CVS repository with cvs2svn.pl 0.51 I run
into the following error:
--! Pass 4: failed 'Could not find single parent for 'start', canditates
was:'ObjMHlpr','v6_0','CLLib','v1_3','athal','DBDDb-1','zcrdlpo','Utils'
Please, read about this event to avoid this error: SymDiffParent' in 1
(for 27 total) seconds.
As far as I understand the problem is that I gave the same stupid
"start" vendor tag to a bunch of projects when importing them into CVS.
As far as I understand cvs2svn tells me to look at the SymDiffParent
event. First problem, there is no SymDiffParent event but a
DiffSymParent. Is is a spelling problem (beside there is a trivial
spelling problem: "canditates" instead of "candidates" in the error
message). Second problem, if I rerun cvs2svn.pl with "-i DiffSymParent"
I still run into the same error.

Oh, I totally get that. I'm just saying that often people refer to a
script without it's .pl or .py or .sh or ... "cvs2cl", for example, is
many times found as cvs2cl.pl. "cvs2svn" is found as cvs2svn.py. To
be honest, when I say cvs2svn.pl the first time, I thought, "Hm,
somebody has actually gone through the trouble of porting cvs2svn.py
to Perl." Obviously, this isn't what you've done, but...
Can you the see the opportunity for confusion here, and how it could
have really easily been avoided?
Sorry. I should be talking about this on your new list. :-)

I named my *project* (not only script, but whole project)
cvs2svn.pl, distribution archive named `cvs2svn.pl' (not simple
`cvs2svn'), you could not see it, but directory on my SVN
repository named `cvs2svn.pl'. Full name of my project is cvs2svn.pl.

Good point. I agree. I'll prepare list form my script today.

Visible test suit is FreeBSD repository at point of version 4.7. Is
it enough? Some parts of it could not be converted with my script
due to FATAL errors (like revisions 1.1.2.1, which is format
violations, etc). But parts, which could be PARSED converted well
with some help from user, and FAILED without this help.
Also, I've tested my script on test suite from cvs2svn.py. Only three
errors was found. And they are fixed now (and fixes will be in next
release).
Also, my script is over-paranoid by default *especially* to avoid
historical data loss. It is like a cat: ``when you are not sure,
wash yourself''. My script, when it is not sure, asks user. It will
complain about DOZENS situations, when it will works properly with
simple ignoring occurred ``error''. I think, that better here will
be second try with options from user, than some ambiguous decision
will be done, because `any of these elements could be selected, this
element is first in array, lets select it'.
And cvs2svn.py with "big visible test suite" munch many parts of
FreeBSD repository (and repositories of my project!) without any
error, and after that dump are broken or created from this dump
repository contains bad branches, etc.
Also, I don't see how I could help cvs2svn.py -- I could not give
any hints to it, but --only-trunk, which is not a solution in most
cases :(

Not that this is any of my business, I actually agree with #2, but #3
sounds too protectionist. You're assuming too much. Lev might actually
be doing a good job promoting Subversion in his own way, and the
principal difference with cvs2svn[.py] that I see is that the .pl
provides more controls for users. They may choose to use it.
I can understand your disappointment though because of the confusion
created by this script.
Sergey.

I've got another one right here:
3. cvs2svn.py is the result of hundreds of man-hours and a helluva lot
of careful testing of a helluva lot of tricky edge cases, gargantuan
repositories, and busted RCS files. Why should I trust my
*historical*data* to a script that has no visible test suite?

Christophe, this is not aimed at you. I'm just using your mail as a
springboard.
I have two strong opinions regarding cvs2svn.pl:
1. It is carelessly named, as it will inevitably be confused with
cvs2svn.py. My recommendation is that the author be a little
more creative, and a lot more sensitive to the fact that
scripts are often referred to without their
interpreter-indicating filename extensions. In my mind,
"cvs2svn" *means* cvs2svn.py -- don't mess with my head.
2. It is not part of Subversion itself, does not live in
Subversion's tree, and is not distributed with Subversion. So
please, while it's fine to announce new releases here, kindly
take further discussion to a list dedicated to this entirely
different product.
