Make etlas.dhall the default configuration file for etlas #66

jneira · 2018-08-10T10:12:48Z

As described in typelead/eta#704 (comment).
Here we can track the progress and specific issues about. The plan would be:

Make default build (cabal new-build) work with etlas.dhall as the default configuration file
- etlas will pick up etlas.dhall if present and ${project-name}.cabal otherwise
Make old-build (cabal build) works in a similar way
Analyze and improve performance.See
Integrate the handling of etlas.dhall file in other etlas commands if needed: init (important!), info, ~~check~~, format (undocumented!), etc
Document the use of dhall to configure etlas in https://eta-lang.org/docs/user-guides/etlas-user-guide

I manged to implement a initial version that uses etlas.dhall but testing it with https://github.com/jneira/wai-servlet/blob/master/etlas.dhall and i've got an error 😞 :

Error:
    Dependency on unbuildable (i.e. 'buildable: False') library from base
    In the stanza 'library'
    In the inplace package 'wai-servlet-0.1.5.1'

rahulmutt · 2018-08-10T11:36:09Z

@jneira Can you share the output with -v3? It may be failing inside of etlas-cabal.

rahulmutt · 2018-08-10T11:37:05Z

Also can you add a debug log in etlas that dumps the parsed GenericPackageDescription from the etlas.dhall file?

rahulmutt · 2018-08-10T12:02:08Z

@jneira Any particular reason for:

jneira@5048002#diff-2d388570b233aa3bd5298e03db1e93c8L512

Shouldn't it be ["./etlas.dhall", "./*.cabal"]?

jneira · 2018-08-10T12:17:29Z

That was my first version but then etlas requires both files and throwed an error if etlas.dhall was not present. Maybe it should change to make it required only one of them.

rahulmutt · 2018-08-10T12:20:24Z

Oh right, that field is for required files. Then it looks ok.

jneira · 2018-08-13T09:39:30Z

I've found the error is thrown here: https://github.com/typelead/etlas/blob/master/etlas-cabal/Distribution/Backpack/ConfiguredComponent.hs#L172
At this point i've traced the package description of a succesful build with .cabal file and the erroneous one with etlas.dhall (https://gist.github.com/jneira/58e57a6f186e55297e3197045f4788fb)
The diff that cause the error is in the BuildDepends field at package level: with .cabal it is informed with the dependencies of all the components of the package, in the dhall case it is empty
In etlas/cabal that field has a doc annotation:

 -- | YOU PROBABLY DON'T WANT TO USE THIS FIELD. This field is
        -- special! Depending on how far along processing the
        -- PackageDescription we are, the contents of this field are
        -- either nonsense, or the collected dependencies of *all* the
        -- components in this package.  buildDepends is initialized by
        -- 'finalizePD' and 'flattenPackageDescription';
        -- prior to that, dependency info is stored in the 'CondTree'
        -- built around a 'GenericPackageDescription'.  When this
        -- resolution is done, dependency info is written to the inner
        -- 'BuildInfo' and this field.  This is all horrible, and #2066
        -- tracks progress to get rid of this field.

So DhallToCabal ignores that field and left it empty
I guess etlas is filling it at some point for .cabal format but no with etlas.dhall
Another diff that maybe is related: the field custom-setup has value Nothing in the .cabal version but Just (SetupBuildInfo {setupDepends = [], defaultSetupDepends = True}), although the default value for it in dhall-to-etlas is [] : Optional types.CustomSetup (and in the source Dhall.field "custom-setup" ( Dhall.maybe setupBuildInfo ))

rahulmutt · 2018-08-13T09:46:53Z

@jneira Maybe you can try populating buildDepends in dhall-to-etlas temporarily to see if that fixes it?

jneira · 2018-08-13T09:58:29Z

Mmmm, that would be a solution but as i have to see how etlas does it maybe i can see where it does and hopefully fix in etlas itself, if possible

rahulmutt · 2018-08-13T10:02:54Z

Sure that works too!

jneira · 2018-08-14T07:03:11Z

The problem seems to be in the initial parse of config files, comparing the GenericPackageDescription generated by cabal internal parser and dhall-to-etlas we can check that dhall-to-etlas is not filling the CondNode.condTreeConstraints in any component. There is the info of conditional dependencies of the component.
That difference was not catched by dhall-to-etlas tests cause they are testing the output of showGenericDescription and it is equal without condTreeConstraints info

rahulmutt · 2018-08-15T05:02:46Z

Does filling in those fields properly fix the issue you were hitting?

jneira · 2018-08-20T06:21:33Z

@rahulmutt yeah, i think dhall-to-etlas should fill it when parsing the file in this function.
In the meanwhile i've change the code to reparse the GenericPackageDescription from dhall with Cabal itself although it is terribly inefficient.
Otoh thinking twice about defaultImplicitProjectConfig.defaultPackages i think we cant left it empty and use cause using projectPackagesOptional makes cabal build the package twice, one using dhall fille and another one using the cabal file. As it uses "glob" to find files we cant use (./etlas.dhall)|(./*.cabal) to use one file or another.

rahulmutt · 2018-08-20T07:50:17Z

@jneira That workaround seems OK for now, let's just focus on correctness first and then we'll worry about performance.

To fix that problem of building package twice, we need to do a filtering before returning with the concat arguments in findProjectPackages. The filtering works like this:

Find all ProjectPackageLocalCabalFile and ProjectPackageLocalDhallFile that share the same parent directory. If such pairs are found, filter out the ProjectPackageLocalCabalFile and go with the ProjectPackageLocalDhallFile.

Jyothsnasrinivas · 2018-09-04T07:23:47Z

This is great news @jneira! :D

jneira · 2018-09-12T08:47:51Z

Performance of parsing dhall config files:

Non-cached version 😐

D:\ws\eta\eta-test>etlas clean -v3
....
Reading package configuration from .\etlas.dhall
Configuration readed in 10.9980705 seconds
....

Import with hash non-cached 😟

D:\ws\eta\eta-test>type etlas.dhall
./etlas.raw.dhall sha256:e036b394eb43c044f3ef6fbcbd92c4ddac88ad4ce2bf8c5ac2cbba66d0e23185
D:\ws\eta\eta-test>etlas clean -v3
....
Reading package configuration from .\etlas.dhall
Configuration readed in 17.3785114 seconds
....

Import with hash cached 😄

D:\ws\eta\eta-test>etlas clean -v3
....
Reading package configuration from .\etlas.dhall
Configuration readed in 0.1092007 seconds
....

So we must use the cached version whenever possible. The computation of the hash takes the same time that parsing itself (cause dhall caches the normalized version) so we should find out the way to get the content and the hash at same time, in one step. Then we should save the import hashed dhall file in dist/cache/import.etlas.dhall and use it while the modification time of the original etlas.dhall file is older.
I am afraid that those 17 seconds are unavoidable in each etlas.dhall file change but let's hope the performance of dhall parsing improves.

rahulmutt · 2018-09-12T10:03:42Z

Great analysis @jneira! That 17 seconds is a bit much. I think a performance target should be to get it down to at least 3 seconds - it's OK if it's a couple seconds slower than the .cabal file format since it adds more power/re-use.

Users will typically not change their .cabal files very often, but they shouldn't have to think twice to make changes b/c of perf issues!

jneira · 2018-09-12T10:19:23Z

Well, another option is to use a derived .cabal file as "cache" file cause it is parsed faster. In that way users will have to wait 10 seconds in each dhall file change.

jneira · 2018-10-22T06:58:28Z

After updating etlas to use dhall-1.18.0 and dhall-to-etlas-1.4.0.0 the performance has improved but continue being not satisfactory:

Without caching dhall-to-etlas prelude nor etlas.dhall

D:\ws\eta\eta-test>etlas clean -v3
no user package environment file found at D:\ws\eta\eta-test
Reading package configuration from .\etlas.dhall
Configuration readed in 8.1900525 seconds
Using internal setup method with build-type Simple and args:
["clean","--verbose=3","--builddir=dist"]

With dhall-to-etlas prelude cached and dhall.etlas not cached

D:\ws\eta\eta-test>etlas clean -v3
no user package environment file found at D:\ws\eta\eta-test
Reading package configuration from .\etlas.dhall
Configuration readed in 6.3024404 seconds
Using internal setup method with build-type Simple and args:

First run after setting hash for etlas.dhall (the usual initial case after change etlas.dhall)

D:\ws\eta\eta-test>etlas clean -v3
no user package environment file found at D:\ws\eta\eta-test
Reading package configuration from .\etlas.dhall
Configuration readed in 10.3272662 seconds
Using internal setup method with build-type Simple and args:
["clean","--verbose=3","--builddir=dist"]

With etlas.dhall already cached

D:\ws\eta\eta-test>etlas clean -v3
no user package environment file found at D:\ws\eta\eta-test
Reading package configuration from .\etlas.dhall
Configuration readed in 0.1092007 seconds
Using internal setup method with build-type Simple and args:
["clean","--verbose=3","--builddir=dist"]
cleaning...

Although times are better, i think the threshold should be 5 seconds for the worst case for being acceptable, that is, when user changes the etlas.dhall file and etlas has to force caching freezing ad reading it.

jneira · 2018-10-23T09:47:01Z

Hi, i've done some tests with the new config files, <pkg-name>.etlas and etlas.dhall:

Uploading a package with each file as main config file in my fork of etlas-index: https://github.com/jneira/etlas-index/tree/master/packages/eta-test
- Version 0.1.0.0 with eta-test.etlas
- Version 0.2.0.0 with etlas.dhall
Trying to execute etlas old-install with each version
Trying to execte etlas build on a package with both versions of eta-test as dependency

The unique test that fails is etlas old-install eta-test-0.2.0.0 (the version with etlas.dhall):

etlas.exe: Error Parsing: file "dist\etlas.dhall.cabal" doesn't exist. Cannot
continue.
etlas: Leaving directory 'C:\TEMP\etlas-tmp-8040'

So the dhall file is parsed and used, the derived cabal file writed (not error in that step) but eta does not find it. Maybe the write is failing silently cause the dist folder soes not exist... to investigate and fix 🤔

rahulmutt · 2018-10-25T02:03:25Z

From a cursory glance at the logs, I notice that the dhall parsing code uses relative paths, so perhaps the derived cabal file is being written to the dist directory of the current directory of the etlas process? Perhaps you need to be writing to C:\TEMP\etlas-tmp-8040\dist\etlas.dhall.cabal?

etlas build works with a dist folder relative to the current directory, so it makes sense that it works. But there is a case in which it doesn't:

directory structure

- eta-test
  - eta-test2
    - etlas.dhall (some basic stub file)
  - cabal.project

cabal.project

packages: eta-test2

Run the following:

cd eta-test2
etlas build

In this case, it should create the dist directory inside of eta-test and not inside of eta-test2 since new-build system uses a centralized dist directory for all the packages you're building for a given cabal.project file. Hence, if relative directory mismatch is the problem, probably this should fail as well? Unless the new-build codepath for dhall passes in the paths properly.

rahulmutt · 2018-11-26T19:13:21Z

That's amazing @jneira! Thank for you all the work for making dhall practical :)

As described in typelead#66 (comment)

jneira · 2018-12-02T01:23:21Z

With #83 we'll got the new performance improvements and the fix to etlas old-install of remote packages with etlas.dhall files.

jneira · 2018-12-08T22:47:47Z

The performance of etlas using dhall has improved and it is below 5 seconds:

Without caching

C:\Users\Javier\dev\lang\eta\eta-test>etlas clean -v3
...
Reading package configuration from .\etlas.dhall
Configuration readed in 4.75 seconds

First time after using hash

C:\Users\Javier\dev\lang\eta\eta-test>etlas clean -v3
...
Reading package configuration from .\etlas.dhall
Configuration readed in 8.6875 seconds

After caching

C:\Users\Javier\dev\lang\eta\eta-test>etlas clean -v3
...
Reading package configuration from .\etlas.dhall
Configuration readed in 0.296875 seconds

So it is way better but not enough to use it without cache.
However we need to cache it in each change and it would be still slow. Possible solutions:

Use a derived cabal file as "cache" cause it is fast to write and read
Launch the dhall caching in parallel in the first build after change, to not slow down.

rahulmutt · 2018-12-09T03:49:31Z

However we need to cache it in each change and it would be still slow. Possible solutions:
* Use a derived cabal file as "cache" cause it is fast to write and read

This sounds like a great idea.

* Launch the dhall caching in parallel in the first build after change, to not slow down.

Can you elaborate on this? So are you saying that it's taking 4.75 seconds because caching is happening in addition to parsing? w/o caching how much time would it take?

jneira · 2018-12-09T14:51:50Z

The second option would be read the changed dhall file (in 4.75 s), start to build immediately in one thread and start another one to cache the readed data (that hopefully will end in 4 seconds aprox.)
Not sure how can interact both processes and maybe it is too much work to avoid 4 seconds.

jneira · 2019-01-29T12:43:10Z

Finally we've implemented a cache of etlas.dhall using builtin dhall cache mechanism: #88
But the cache invalidation depends on the hash of dhall.etlas, each change in the file will trigger the read and cache steps.

jneira · 2019-02-05T11:24:26Z

@rahulmutt has made good points about the usage of the dhall format in etlas config context: see typelead/eta#946

jneira · 2019-02-07T13:51:55Z

With #96 etlas init will generate an etlas.dhall by default.

jneira · 2019-02-15T10:01:06Z

possible improvements

etlas freeze --format=dhall: make a etlas.dhall.freeze with all dependencies pinned to a single version and all dhall imports hashed (with an optional argument --in-place to update the default one?)
etlas format : apply dhall format to etlas.dhall
etlas check: apply dhall lint to etlas.dhall to get possible warnings (without changing it)
using templates in etlas init to generate the default etlas.dhall. The templates and possible values would be dhall files themselves. Ideally etlas init should use it on the fly to ask the questions in interactive mode. Maybe this one could be a separate library/executable

jneira · 2019-02-20T07:28:13Z

To make etlas.dhall more resilient and make it work oflline we should (as suggested in dhall-lang/dhall-lang#378):

Download and put in dhall cache all core imports (types, prelude and default dependencies) inside ~/.etlas
Replace the file remote imports matching the urls for the local ones before evaluate etlas.dhall

rahulmutt · 2019-02-21T11:29:01Z

@jneira Sounds like a nice idea. Do you think this would make the performance even better?

jneira · 2019-02-21T20:42:56Z

Definitely it will for dependencies.dhall cause it can change and we should not freeze with a hash by default. I was thinking in downloading it as part of etlas update.

I've requested a pr to bump up dhall version to 1.23: #102
This version has improved nomalization perf so:

Reading and caching package configuration from dhall file: .\etlas.dhall
Configuration readed in 4.836031 seconds

@jneira That's wonderful! What are the remaining tasks for this issue?

jneira · 2019-05-15T06:00:23Z

Mmm, i think only left use a local copy of imports as suggested in #66 (comment)

jneira · 2019-11-04T13:50:01Z

I've updated dhall support for 1.26.1 of dhall-to-etlas and etlas: #108
