Version 1.15.0 -- 2021-10-29
|
|
----------------------------
|
|
|
|
This is a bugfix release. It changes how Litani spawns commands so that it can
|
|
correctly terminate the command and all descendant processes if the job has an
|
|
associated timeout.
|
|
|
|
|
|
Version 1.14.0 -- 2021-10-21
|
|
----------------------------
|
|
|
|
- This release introduces custom stage names to Litani. It also improves the
|
|
user experience by showcasing better synopses for jobs in the pipeline graphs
|
|
as well as a pipeline summary at the top of the dashboard. Finally, this
|
|
release also contains other QoL changes.
|
|
|
|
|
|
|
|
Version 1.13.0 -- 2021-09-29
|
|
----------------------------
|
|
|
|
- This version fixes a bug where artefact directories were not being
|
|
copied correctly
|
|
|
|
|
|
|
|
Version 1.12.0 -- 2021-08-24
|
|
----------------------------
|
|
|
|
- The --phony-outputs flag now has a slightly changed semantic
|
|
Outputs passed to --phony-outputs no longer need to be also passed
|
|
to --outputs to be considered an output. That is, the set of outputs
|
|
of a job is the union of the outputs and the phony outputs. This is
|
|
a backward-compatible change that should make configure scripts
|
|
shorter.
|
|
|
|
- The `dump-run` command is more reliable when being run in parallel
|
|
|
|
|
|
|
|
Version 1.11.1 -- 2021-08-16
|
|
----------------------------
|
|
|
|
- Make dependency on graphviz optional
|
|
|
|
|
|
|
|
Version 1.11.0 -- 2021-08-13
|
|
----------------------------
|
|
|
|
- Added --phony-outputs flag to litani add-job
|
|
- Added litani dump-run command
|
|
- Added auto-generated documentation for run.json schema
|
|
- Added more documentation
|
|
|
|
|
|
|
|
Version 1.10.0 -- 2021-07-11
|
|
----------------------------
|
|
|
|
- "aux" key added to run API
|
|
This is intended for users to fill out their own custom data when
|
|
processing the run.json file. The run.json file has a tightly
|
|
specified schema that allows for no additions, but the "aux" key
|
|
provides a way to add arbitrary data to a run.
|
|
|
|
- UI improvements
|
|
The parallelism graph now shows the number of processing cores as a
|
|
horizontal line, and the job memory usage section of the dashboard
|
|
now displays a message if no memory trace was captured.
|
|
|
|
|
|
|
|
Version 1.9.0 -- 2021-06-29
|
|
---------------------------
|
|
|
|
- Manual pages
|
|
Litani now has work-in-progress documentation, currently including
|
|
man pages for the three most commonly-used subcommands
|
|
|
|
- Gnuplot dependency is now optional
|
|
This is to support users who run Litani in minimal containers
|
|
|
|
- Improved usability of output directory symlink
|
|
Litani init now prints the path to the symlink by default, unless
|
|
the new --no-print-out-dir flag was passed
|
|
|
|
|
|
|
|
Version 1.8.0 -- 2021-06-24
|
|
---------------------------
|
|
|
|
- Job pool
|
|
Users can now add jobs to a particular "job pool", which limits the
|
|
parallelism of those jobs. Multiple pools can be created, each with
|
|
their own parallelism limits. This is intended to inhibit the
|
|
parallelism of jobs that use a contended resource, like disk I/O or
|
|
network bandwidth.
|
|
|
|
- UI improvement on pipeline page
|
|
Each job on the pipeline page now has a hyperlink to that job,
|
|
making it easy to link to particularly interesting jobs hosted on
|
|
the web.
|
|
|
|
- Memory profiler
|
|
Litani can now profile the memory of particular jobs and display
|
|
graphs of those jobs' memory use on the dashboard. This can be
|
|
helpful when deciding when to place particular jobs into a job pool.
|
|
|
|
- Parallelism measurement
|
|
Litani now tracks how many jobs are running in parallel at any one
|
|
moment, and displays that as a graph on the dashboard. This can be
|
|
helpful when trying to increase CPU core utilization or trying to
|
|
use cloud resources as efficiently as possible.
|
|
|
|
|
|
|
|
Version 1.7.1 -- 2021-05-13
|
|
---------------------------
|
|
|
|
- This minor release fixes a bug with the graph renderer.
|
|
|
|
|
|
Version 1.7.0 -- 2021-05-12
|
|
---------------------------
|
|
|
|
- The --outcome-table flag can be used to specify a JSON file that
|
|
Litani uses to decide whether a job was successful.
|
|
|
|
- The --output-directory flag can be used to specify where Litani should
|
|
write its output files.
|
|
|
|
- The --output-symlink flag can be used to create a symbolic link to the
|
|
output directory.
|
|
|
|
- The --output-prefix flag is an alternative to --output-directory that
|
|
specifies a directory, into which Litani will create a unique
|
|
directory for writing its output files.
|
|
|
|
- Litani now displays a table of contents on each pipeline page. Each
|
|
entry in the table of contents is a hyperlink that points to a job on
|
|
the page.
|
|
|
|
- Litani now renders each pipeline as a graph and displays that graph on
|
|
the pipeline page, allowing users to see the dependency layout of all
|
|
the jobs in the pipeline.
|
|
|
|
|
|
Version 1.6.0 -- 2021-03-10
|
|
---------------------------
|
|
|
|
This release fixes a bug where litani would crash when given the
|
|
`--timeout` option.
|
|
|
|
|
|
Version 1.5.0 -- 2021-03-08
|
|
---------------------------
|
|
|
|
- The implementation of directory locking no longer releases the lock
|
|
upon creation. This fixes a problem where external processes could
|
|
release a lock that a different process had acquired.
|
|
|
|
|
|
Version 1.4.0 -- 2021-03-02
|
|
---------------------------
|
|
|
|
- lib.litani now exposes a LockableDirectory API that can be used to
|
|
lock directories against concurrent access by more than one process.
|
|
External processes can use this API to lock report directories while
|
|
reading or copying them.
|
|
|
|
- Litani now touches a file called `.litani-expired` in HTML report
|
|
directories as soon as a new report directory has been written, and
|
|
after the `html` symbolic link has been updated to point to the new
|
|
directory. Litani then deletes all report directories that are both
|
|
expired and unlocked.
|
|
|
|
|
|
Version 1.3.0 -- 2021-02-24
|
|
---------------------------
|
|
|
|
- Litani now has a top-level command called `print-capabilities` that
|
|
prints out a list of features in either human or machine-readable format.
|
|
The intention is that any new API-changing features will be accompanied by a
|
|
new entry in this list
|
|
|
|
|
|
Version 1.2.0 -- 2021-02-24
|
|
---------------------------
|
|
|
|
- Litani now renders the HTML directory atomically. The `html` directory is now
|
|
a symbolic link that is updated only after the report has been completely
|
|
written.
|
|
- Added dark mode for all report pages
|
|
|
|
|
|
Version 1.1.0 -- 2021-02-03
|
|
---------------------------
|
|
|
|
- Added a new top-level command, `litani graph`. This dumps a
|
|
Graphviz-formatted graph to stdout that describes the dependency graph
|
|
of the jobs that have been added so far.
|
