makediff test steps
|
|
1. launch weed server at your local/dev environment, (option
|
|
"garbageThreshold" for master and option "max" for volume should be set with specific value which would let
|
|
preparing test prerequisite easier )
|
|
a) ./weed master -garbageThreshold=0.99 -mdir=./m
|
|
b) ./weed volume -dir=./data -max=1 -mserver=localhost:9333 -port=8080
|
|
2. upload 4 different files, you could call dir/assign to get 4 different fids
|
|
a) upload file A with fid a
|
|
b) upload file B with fid b
|
|
c) upload file C with fid c
|
|
d) upload file D with fid d
|
|
3. update file A and C
|
|
a) modify file A and upload file A with fid a
|
|
b) modify file C and upload file C with fid c
|
|
c) record the current 1.idx's file size(lastCompactIndexOffset value)
|
|
4. Compacting the data file
|
|
a) run curl http://localhost:8080/admin/vacuum/compact?volumeId=1
|
|
b) verify the 1.cpd and 1.cpx is created under volume directory
|
|
5. update file B and delete file D
|
|
a) modify file B and upload file B with fid b
|
|
d) delete file B with fid b
|
|
6. Now you could run the following UT case, the case should be run successfully
|
|
7. Compact commit manually
|
|
a) mv 1.cpd 1.dat
|
|
b) mv 1.cpx 1.idx
|
|
8. Restart Volume Server
|
|
9. Now you should get updated file A,B,C
