How do I determine the SVN working copy layout version?
Solution 1
If .svn/format
exists, then read the number in it:
- Version 7 is SVN 1.3
- Version 8 is SVN 1.4
- Version 9 is SVN 1.5
If .svn/format
doesn't exist then the version number is on the first line in .svn/entries
:
- Version 10 is SVN 1.6
- Version 12 is SVN 1.7
Subversion 1.6 was the first one not to use .svn/format
. Version 7 and older used XML-based .svn/entries
file, newer versions use less verbose line-based file format.
Since Subversion 1.7 the version number is stored in the .svn/wc.db
SQLite database in the "user_version" field. So even though .svn/format
is bumped to version 12 the actual format version is 29 and future versions may not update .svn/format
anymore. To obtain the version number from .svn/wc.db
there are two methods:
- if you have
sqlite3
in your path,sqlite3 .svn/wc.db "PRAGMA user_version"
- if you DO NOT have
sqlite3
in your path, open.svn/wc.db
in a hex editor and read the DWORD at offset 0x3c
All the format version numbers are described in wc.h along with the version numbers of respective Subversion releases.
Solution 2
From Stack Overflow question Find out SVN working copy version (1.7 or 1.8):
One can use sqlite3 .svn/wc.db "PRAGMA user_version"
on SVN 1.7 or later (or od -An -j63 -N1 -t dC .svn/wc.db
if you only have the SQLite 3.0 libraries, YMMV).

For example, the SVN 1.5 client has one layout for working copies, and the SVN 1.6 client has a different layout. I understand that the layout automatically gets upgraded when it gets touched by a newer client.
If I have a working copy on my system, how can I find out the version of the layout it's using?

Sharique Abdullah almost 12 yearsMy file has format value = 4. This does not make sense. Does it ?
-
Filip Navara almost 12 years@ShariqueAbdullah I believe version 4 corresponds to the original Subversion 1.0 release, but I could be mistaken.
-
Charles Duffy about 11 years@ShariqueAbdullah That sounds more like a repository format version than a remotely modern working copy format version.

Kai almost 11 yearsAs of Subversion 1.8, this method is sadly broken.
-
Filip Navara almost 11 yearsI've already updated the answer to mention that Subversion 1.7+ stores the version number in the SQLite database (pragma user_version). The link to wc.h also contains the relevant version number for Subversion 1.8.

smile.al.d.way over 9 yearslink to wc.h is broken now. Do we have a new link?

od
command works on my system which I believe lacks the SQLite libraries. Thanks!
