Hi All,
These are my doubts.
(1) When we checkout the project from svn,a new hidden folder .svn
also cmes in to picture.When I opened the folder, I saw these sub
folders prop-base, text-base,props, tmp and files namely,dir-prop-
base and entries.What is the significance of these subfolders and
files and how svn is able to track changes with this hidden folder.
I tried googling but couldn't find useful results.
Subversion uses these .svn folders to track your working copy. They
tell Subversion what URL was checked out, version, etc. Do not touch
anything in these .svn directories. CVS does something similar with
CVS directories.
(2) Where actually svn keeps the pristine copy..is it in .svn
hidden folder?
Yes. That's why Subversion can tell you what files were changed and do
diffs without talking to the server. It makes Subversion pretty fast.
(3) Can we set image file as a property value...But as i tried
opening from command prompt (Windows) using propget command...it
didn't work..I also tried retreiving value using subclipse also...it
din't work...What can be the reason?
Property values are text strings. You can have the text string be
equal to an image file's name. You can attach a property to Amy file
or directory -- even image files.
(4) In subverson 1.7 , every article is talking about next
generation working copy...what exactly does it do..please explain
such that a new-bie like me can understand.They all are talking
about centralized meta-data storage...what does it mean...??..is it
a single .svn folder for the whole project instead of one per folder/
subfolder..??
I don't do Subversion development, so I don't follow the development
roadmap too carefully. It sounds like they're redoing the working
copy meta-data (the stuff in the .svn folders you're not suppose to
touch to add features like off line commits and shelving.
At one time the developers were discussing the possibility of taking
the .svn directories out of the working copy, but that was difficult
to do. There is one .svn directory per checked out directory for
programming reasons. You don't have to search an entire directory tree
to find that info or talk to the server.
(5) While comparing svn and cvs, it is said that branchin & taggin
is faster in svn than in cvs...I haven't used cvs...Can u explain
vat could be the possible reason...??..svn uses svn copy to branch/
tag...bt vat does cvs use??...& why is it slow?
Most source control systems including CVS tag each individual file in
the repository with a tag. If you have 30,000 files in your release,
you have to tag 30,000 files on the server Subversion tags the entire
release with a single tag. What use to take 30-40 minutes to tag in
CVS now takes a frction of a second.
