Hi subversion-dev-team :)
I experiment with the new fsfs about once a week and
continued to get the same exception every time.
I know fsfs is far from beeing complete yet,
but I thought maybe I should report this.
WinXP-SP1 system, svn rev 9654 build with MSVC7.2
using file:/// protocol and --fs-type fsfs,
when running two commits simultaneously, i get an
exception in svn_fs_abort_txn due to a zero vtable
pointer and other strange effects.
reproduction receipe is like this:
- create fsfs repo
- checkout repo as "work"
- add dummy file 'version.h' in work1/
- checkout repo as "work2"
- add dummy file 'version2.h' in work2/
in two consoles simultaneously do:
- console1 in work/
loop {
echo randomnumber >version.h
svn commit -m"random"
}
- console2 in work2/
loop {
echo randomnumber >version2.h
svn commit -m"random"
}
there are NOT crashes or strange errors when only
one console is active. so it must have something
todo with concurrent repository access.
this results in varying error messages,
crashes or lockups, like (1,2,3,4) below,
at random.
the traceback for the crash-case is below.
