### Please describe the problem.
|
||||
background: I'm trying to use git-annex to manage tracking/off-site replication of a borgbackup repository. This requires direct access to files, and it's not feasible for me to operate without annex.thin set. I'm trying to workaround some of borg's inconvenient behavior--sometimes, a borg transaction will do something that is effectively just a file rename, but internally, it truncates+deletes the original file and creates a new file with the old content. This leads to annex adding the "new" file as a reference to known content, but that content was already lost. (maybe) MWE below
|
||||
|
||||
### What steps will reproduce the problem?
|
||||
set -x && \
|
||||
mkdir tmp && cd tmp && \
|
||||
git init && \
|
||||
git-annex init --version 7 base && \
|
||||
git-annex config --set annex.thin true && \
|
||||
\
|
||||
echo "bar">foo && cat foo && git-annex add foo && ls -l && git-annex unlock foo && git-annex sync && \
|
||||
truncate -s 0 foo && rm foo && git-annex sync && \
|
||||
\
|
||||
echo "bar">ffoo && cat ffoo && git-annex add ffoo && ls -l && git-annex unlock ffoo && git-annex sync && \
|
||||
cat ffoo && git-annex whereis && git-annex fsck

### Have you had any luck using git-annex before? (Sometimes we get tired of reading bug reports all day and a lil' positive end note does wonders)
|
||||
I'm hopeful! But just getting started :(
