I have three boxes running the latest build of Subversion under
Win98. Compilation all happened without a hitch. I have svn.exe and
svnadmin.exe binaries built, as well as all the Berkeley db_xxx.exe
tools. From the looks of it, I should have a working local
repository.
But.
After a successful run of `svnadmin create repos' (in c:\), I have the
following:
. <DIR> 05-10-01 10:19a .
.. <DIR> 05-10-01 10:19a ..
LOG~1 000 67,994 05-10-01 10:19a log.0000000001
NODES 16,384 05-10-01 10:19a nodes

STRINGS 16,384 05-10-01 10:19a strings
TRANSA~1 16,384 05-10-01 10:19a transactions
__DB 001 8 05-10-01 10:19a __db.001

__DB 003 0 05-10-01 10:19a __db.003
__DB 004 0 05-10-01 10:19a __db.004
__DB 005 0 05-10-01 10:19a __db.005
10 file(s) 133,538 bytes
2 dir(s) 33,768.03 MB free
Now, I'm not entirely certain, but the sizes of those index files
look kinda scary. I can use db_dump to see all the tables themselves
with no complaints (nodes, revisions, transactions, strings), but any
time I programmatically to try to access the database, an error
occurs. For example:
C:\repos>svnadmin lsrevs .
svn_error: #21055 Berkeley DB error while opening environment
for filesystem .:
Resource temporarily unavailable
Now, I traced into the BDB code far enough to find where it fails.
BDB is trying to open the file "repos\__db.001", and is doing all
kinds of fun memory-mapping stuff, but once it's done so, it appears
to be reading some "region" information (a REGENV structure) from the
file, and when it can't find its magic thumbprint (DB_REGION_MAGIC),
it whines and quits.
So I looked at output of the same command when run in Linux:
-rw-r--r-- 1 cmpilato users 8192 May 10 10:26 __db.001
-rw-r--r-- 1 cmpilato users 270336 May 10 10:26 __db.002
-rw-r--r-- 1 cmpilato users 98304 May 10 10:26 __db.003
-rw-r--r-- 1 cmpilato users 319488 May 10 10:26 __db.004
-rw-r--r-- 1 cmpilato users 8192 May 10 10:26 __db.005
-rw-r--r-- 1 cmpilato users 35226 May 10 10:26 log.0000000001
-rw-r--r-- 1 cmpilato users 8192 May 10 10:26 nodes
-rw-r--r-- 1 cmpilato users 8192 May 10 10:26 revisions
-rw-r--r-- 1 cmpilato users 8192 May 10 10:26 strings
-rw-r--r-- 1 cmpilato users 8192 May 10 10:26 transactions
I took a look at the binary goo inside the Unix-created repository's
__db.001 file, and at the top, I saw actual header information,
including Berkeley's magic number. In fact, I found it really odd
that the index files under Windows where zero-length (except that one
odd 8-byte one), but under Unix, everything had at least 8k.
I've run into problems with APR in the past where they haven't kept
their MS API docs up-to-date enough to realize that sometimes Win98
doesn't behave exactly like Win95. I don't know if this is a similar
issue for Berkeley. What I do know is that this happens on all three
of my Win98 boxen, and that it kinda puts a dent in my plans to make
sure Subversion is just as great under Windows as it is under Unix! :-)
