As meson processes our DPDK source tree it manages dependencies
specified by each individual driver. To enable future analysis of the
dependency links between components, log the dependencies of each DPDK
component as it gets processed. This could potentially allow other tools
to automatically enable or disable components based on the desired end
components to be built, e.g. if the user requests net/ice, ensure that
common/iavf is also enabled in the drivers.

The output file produced is in "dot" or "graphviz" format, which allows
producing a graphical representation of the DPDK dependency tree if so
desired. For example: "dot -Tpng -O build/deps.dot" to produce the
image file "build/deps.dot.png".

I think it is a great idea.

I tested it quickly, good to have this dependency list, at least it
makes some duplicated dependencies obvious from .dot file.

But generated dependency graph is too large to be useful, does it make
sense to have a new meson option that control this dependency generation:
-Dgenerate_deps=apps
-Dgenerate_deps=libs
-Dgenerate_deps=drivers
-Dgenerate_deps=all

Not sure about what should be the default option,
as this is not always required/used, disabling this option by default
saves unnecessary work,
but disabling it by default may cause not noticing when it is broken,
perhaps this can be addressed by adding this option to
'devtools/test-meson-builds.sh'.

btw, it generates following warning:

WARNING: You should add the boolean check kwarg to the run_command call.


         It currently defaults to false,


         but it will default to true in future releases of meson.

I had indeed noticed that. Right now I'm focused on cutting down our
dependency lists to make things more manageable - I have a script to
automate the identification of excess dependencies and I already have a
patch for cleaning up the libraries to a minimal dependency set.

I also think having separate drivers and libraries charts could be useful I
wouldn't want to add a build option for it though - it's not something that
should be necessary. Instead, I will look at other options, perhaps even
doing multiple dependency files - they don't seem to slow meson down, so
why not always do them all.

Oops - will look to fix in V2.

As part of the meson build, we can record the dependencies for each
component as we process it, logging them to a file. This file can be
used as input to a number of other scripts and tools, for example, to
graph the dependencies, or to allow higher-level build-config tools to
automatically enable component requirements, etc.

The first patch of this set generates the basic dependency tree. The
second patch does some processing of that dependency tree to identify
cases where dependencies are being unnecessarily specified. Reducing
these makes it easier to have readable dependency graphs in future,
without affecting the build.

The following 4 patches are based on the output of the second patch, and
greatly cut down the number of direct dependency links between
components. Even with the cut-down dependencies, the full dependency
graph is nigh-unreadable, so the final patch adds a new script to
generate dependency tree subgraphs, creating dot files for e.g. the
dependencies of a particular component, or a component class such as
mempool drivers.

Bruce Richardson (7):
  build: output a dependency log in build directory
  devtools: add script to flag unneeded dependencies
  build: remove kvargs from driver class dependencies
  build: reduce library dependencies
  build: reduce driver dependencies
  build: reduce app dependencies
  devtools: add script to generate DPDK dependency graphs

As meson processes our DPDK source tree it manages dependencies
specified by each individual driver. To enable future analysis of the
dependency links between components, log the dependencies of each DPDK
component as it gets processed. This could potentially allow other tools
to automatically enable or disable components based on the desired end
components to be built, e.g. if the user requests net/ice, ensure that
common/iavf is also enabled in the drivers.

The output file produced is in "dot" or "graphviz" format, which allows
producing a graphical representation of the DPDK dependency tree if so
desired. For example: "dot -Tpng -O build/deps.dot" to produce the
image file "build/deps.dot.png".

This is invalid syntax prior to Python 3.12. You're doing escaped quotes 
("\", \"") inside a f-string block ({}). My machine has Python 3.9 and 
this breaks the script.

While not a serious problem, DPDK components often list more
dependencies than are actually necessary to build, due to the use of
recursive dependencies. In extreme cases, such as with core libraries,
this can lead to longer configuration times due to meson having to
deduplicate long lists of dependencies. Therefore we can add a script to
identify when a component has got unnecessary dependencies listed.

The kvargs library is used by EAL, and therefore is implicitly a
dependency of every DPDK driver. Remove it from the minimum set of
dependencies for each driver class as it's unnecessary to call it out
there.

Rather than having each library depend up on EAL + any extra libs, we
can take advantage of recursive dependency support in meson and
just assign the dependencies of each directory directly, rather than
appending to the array. For libraries which only depend upon EAL, keep
that as a default, but for libraries which depend upon even a single
extra lib, that EAL dependency is unnecessary.

Going further, we can identify using the find_duplicate_deps.py script
any unnecessary deps in each library's list, and remove them to slim the
dependency tree down.

Reducing number of dependencies means that meson
takes less time processing and deduplicating the dependency tree for
each component, and also shrinks the dependency graph for DPDK itself.

  To: dev; +Cc: ferruh.yigit, konstantin.ananyev, anatoly.burakov, Bruce Richardson

Remove any unnecessary dependencies from the driver dependency lists.
This will give each driver a near-minimum set of required dependencies.

Remove any unnecessary dependencies from the app dependency lists.
This will give each app a near-minimum set of required dependencies.

Rather than the single monolithic graph that would be output from the
deps.dot file in a build directory, we can post-process that to generate
simpler graphs for different tasks. This new "draw_dependency_graphs"
script takes the "deps.dot" as input and generates an output file that
has the nodes categorized, filtering them based off the requested node
or category. For example, use "--component net_ice" to show the
dependency tree from that driver, or "--category lib" to show just the
library dependency tree.

I saw there was one fail for this series for the Marvell MVNETA container.

I thought I should also mention that the build did fail when our
automation tried to run DTS on the Octeon CN10K DPU (which is also
Marvell). So, that is why you won't get a report for the CN10K DTS
results.

Let me know if you can't get what you need from the MVNETA build logs
failure, and I can manually get more info about why this won't
compile. Cheers.

I have already got multiple emails about failures from this series - though
all look to be about the same issue. I think it should be an easy fix for
v3, but I'll waiting till all reports come back.

Thanks for the update, output is now easier to consume with the help of
the 'devtools/draw-dependency-graphs.py' script.
A detail but script is not actually drawing graph, but parsing .dot
file, name is a little misleading.


Also for the patches that are converting explicit dependency to implicit
dependency, I can see the benefit for the meson and graph. But also
there is a value of keeping explicit dependency, it was an easy way to
document dependencies of component for developers.
So, I am not really sure which one is better.

Up till now we did not keep a fully dependency list for each component
because the configuration time with meson completely exploded due to really
slow deduplication of dependencies there. I haven't checked with recent
versions of meson, though, so the problem may no longer be there now. Right
now, we have "partial dependency lists" - neither full list of dependencies
of a component, nor a minimal set. These patches don't bring us fully to a
minimal set, but bring us closer. I honestly don't think we need to enforce
either case - so long as we have all dependencies either explicilty or via
recursive dependency, things are fine.

As part of the meson build, we can record the dependencies for each
component as we process it, logging them to a file. This file can be
used as input to a number of other scripts and tools, for example, to
graph the dependencies, or to allow higher-level build-config tools to
automatically enable component requirements, etc.

The first patch of this set separates dependencies inside meson into
optional or mandatory. The second patch of this set generates the basic
dependency tree. The third patch does some processing of that dependency
tree to identify cases where dependencies are being unnecessarily
specified. Reducing these makes it easier to have readable dependency
graphs in future, without affecting the build.

The following 4 patches are based on the output of the second patch, and
greatly cut down the number of direct dependency links between
components. Even with the cut-down dependencies, the full dependency
graph is nigh-unreadable, so the final patch adds a new script to
generate dependency tree subgraphs, creating dot files for e.g. the
dependencies of a particular component, or a component class such as
mempool drivers.

v2 -> v3:
- Split dependencies into optional and mandatory
- Fixup graph scripts to read and generate graphs that encode optional
  dependencies into the graph
- Python version fixes to avoid using features not available in minimum
  supported Python version
- Formatting with Ruff, and PEP-484 compliance

Allow specifying dependencies as either mandatory or optional. This does
not change anything about the build, but it is useful for tooling to know
if a dependency is required or not.

Hi Bruce,

Please correct me if I'm wrong, but doesn't it essentially do the same 
thing? You're adding a new loop over optional deps, while I'm simply 
extending existing loop to iterate over deps + optional deps, which 
would achieve the same thing?

What does that patch do that this patch doesn't?

Thanks,
Anatoly

Your patch categorises the dependencies into optional and mandatory but
doesn't actually change any code flow logic. My patch doesn't do the
classification changes in the individual components, but changes the higher
level meson.build file to do the checks for optional dependencies and only
add them if they are present. That is, it removes the need for individual
components to check for the optional deps themselves and add them if found.

As meson processes our DPDK source tree it manages dependencies
specified by each individual driver. To enable future analysis of the
dependency links between components, log the dependencies of each DPDK
component as it gets processed. This could potentially allow other tools
to automatically enable or disable components based on the desired end
components to be built, e.g. if the user requests net/ice, ensure that
common/iavf is also enabled in the drivers.

The output file produced is in "dot" or "graphviz" format, which allows
producing a graphical representation of the DPDK dependency tree if so
desired. For example: "dot -Tpng -O build/deps.dot" to produce the
image file "build/deps.dot.png".

While not a serious problem, DPDK components often list more
dependencies than are actually necessary to build, due to the use of
recursive dependencies. In extreme cases, such as with core libraries,
this can lead to longer configuration times due to meson having to
deduplicate long lists of dependencies. Therefore we can add a script to
identify when a component has got unnecessary dependencies listed.

The kvargs library is used by EAL, and therefore is implicitly a
dependency of every DPDK driver. Remove it from the minimum set of
dependencies for each driver class as it's unnecessary to call it out
there.

From: Bruce Richardson <bruce.richardson@intel.com>

Rather than having each library depend up on EAL + any extra libs, we
can take advantage of recursive dependency support in meson and
just assign the dependencies of each directory directly, rather than
appending to the array. For libraries which only depend upon EAL, keep
that as a default, but for libraries which depend upon even a single
extra lib, that EAL dependency is unnecessary.

Going further, we can identify using the find_duplicate_deps.py script
any unnecessary deps in each library's list, and remove them to slim the
dependency tree down.

Reducing number of dependencies means that meson
takes less time processing and deduplicating the dependency tree for
each component, and also shrinks the dependency graph for DPDK itself.

From: Bruce Richardson <bruce.richardson@intel.com>

Remove any unnecessary dependencies from the app dependency lists.
This will give each app a near-minimum set of required dependencies.

* [PATCH v3 8/8] devtools: add script to generate DPDK dependency graphs

  To: dev

From: Bruce Richardson <bruce.richardson@intel.com>

Rather than the single monolithic graph that would be output from the
deps.dot file in a build directory, we can post-process that to generate
simpler graphs for different tasks. This new "draw_dependency_graphs"
script takes the "deps.dot" as input and generates an output file that
has the nodes categorized, filtering them based off the requested node or
category. For example, use "--match net/ice" to show the dependency tree
from that driver, or "--match lib" to show just the library dependency
tree.
