# syz-db | ||
|
||
`syz-db` program can be used to manipulate corpus.db databases that are used | ||
by syz-managers. | ||
|
||
## Build | ||
|
||
Build `syz-db` with `make db` or by changing to `tools/syz-db` and run `go build`. | ||
|
||
## Options | ||
|
||
`syz-db` currently overs the following generic arguments: | ||
|
||
```shell | ||
-arch string | ||
target arch | ||
-os string | ||
target OS | ||
-version uint | ||
database version | ||
-vv int | ||
verbosity | ||
``` | ||
|
||
That can be used with | ||
|
||
``` | ||
syz-db pack dir corpus.db | ||
``` | ||
|
||
to pack a database | ||
|
||
``` | ||
syz-db unpack corpus.db dir | ||
``` | ||
|
||
to unpack a database. A file containing performed syscalls will be returned. | ||
|
||
``` | ||
syz-db merge dst-corpus.db add-corpus.db* add-prog* | ||
``` | ||
|
||
to merge databases. No additional file will be created: The first file will be replaced by the merged result. | ||
|
||
``` | ||
syz-db bench corpus.db | ||
``` | ||
|
||
to run a deserialization benchmark. For example: | ||
|
||
``` | ||
syz-db -os=linux -arch=amd64 bench corpus.db | ||
``` | ||
|
||
could give an output like | ||
|
||
``` | ||
allocs 123 MB (123 M), next GC 123 MB, sys heap 123 MB, live allocs 123 MB (123 M), time 324s. | ||
``` |
