scripts for automated testing of zstd
|
|
================================
|
|
|
|
#### test-zstd-versions.py - script for testing zstd interoperability between versions
|
|
|
|
This script creates `versionsTest` directory to which zstd repository is cloned.
|
|
Then all taged (released) versions of zstd are compiled.
|
|
In the following step interoperability between zstd versions is checked.
|
|
|
|
|
|
#### test-zstd-speed.py - script for testing zstd speed difference between commits
|
|
|
|
This script creates `speedTest` directory to which zstd repository is cloned.
|
|
Then it compiles all branches of zstd and performs a speed benchmark for a given list of files (the `testFileNames` parameter).
|
|
After `sleepTime` (an optional parameter, default 300 seconds) seconds the script checks repository for new commits.
|
|
If a new commit is found it is compiled and a speed benchmark for this commit is performed.
|
|
The results of the speed benchmark are compared to the previous results.
|
|
If compression or decompression speed for one of zstd levels is lower than `lowerLimit` (an optional parameter, default 0.98) the speed benchmark is restarted.
|
|
If second results are also lower than `lowerLimit` the warning e-mail is send to recipients from the list (the `emails` parameter).
|
|
|
|
Additional remarks:
|
|
- To be sure that speed results are accurate the script should be run on a "stable" target system with no other jobs running in parallel
|
|
- Using the script with virtual machines can lead to large variations of speed results
|
|
- The speed benchmark is not performed until computers' load average is lower than `maxLoadAvg` (an optional parameter, default 0.75)
|
|
- The script sends e-mails using `mutt`; if `mutt` is not available it sends e-mails without attachments using `mail`; if both are not available it only prints a warning
|
|
|
|
|
|
The example usage with two test files, one e-mail address, and with an additional message:
|
|
```
|
|
./test-zstd-speed.py "silesia.tar calgary.tar" "email@gmail.com" --message "tested on my laptop" --sleepTime 60
|
|
```
|
|
|
|
To run the script in background please use:
|
|
```
|
|
nohup ./test-zstd-speed.py testFileNames emails &
|
|
```
|
|
|
|
