Cannot build PDFs: notoserif-regular-subset.ttf not found in GEM_FONTS_DIR (v1.8.0 and later) #214

p- · 2021-07-20T08:14:53Z

Hello
Thanks for creating the docker-asciidoctor image!

Since Version 1.8.0 and later, we cannot build PDFs anymore because of this error:

No such file or directory - notoserif-regular-subset.ttf not found in GEM_FONTS_DIR

Do you have an idea what could be the cause?

dduportal · 2021-07-20T09:01:01Z

Hello @p- , thanks for reporting!

Could you provide a reproduction case please?

The reason I'm asking is because the test harness has a PDF generation step that succeeded for the 1.8.0 (or the deploy would never have been done):

The goal would be to add the failing case to the test harness or improve the current test to underline the bug you are reporting, so we could fix it with confidence

dduportal · 2021-07-20T09:05:47Z

I cannot reproduce with the current test case:

I assume there is a directive in your adoc file that triggers the error: if you can share the reproduction, we could add the directive(s) to the test case

p- · 2021-07-20T09:08:35Z

Hi @dduportal
Thanks for looking into this!

I'll have a look at our Adocs and report back, what might be the problem.

p- · 2021-07-20T09:58:58Z

Hi @dduportal

Unfortunately, I have no very good repro at the moment. For some reasons, I seem to get the error with an empty index.adoc too 🤔

This should be the command that seems to lead to the error:
docker run -u 1741:20 -v /tmp[..]/asciidoc/projectSources/:/documents/ asciidoctor/docker-asciidoctor:1.8.0 asciidoctor-pdf --trace /documents/docs/src/developer-documentation/index.adoc

(I have to verify that this is the right command, since it's concated.)

With --trace the exception reads as follow:

Ah I can reproduce the error like this:

docker run -ti --rm -v $(pwd):/$(pwd) -w $(pwd) --entrypoint=bash asciidoctor/docker-asciidoctor:1.8.0

Then create an empty file inside the docker container (it's the same for files with content):

bash-5.1# touch index.adoc
bash-5.1# asciidoctor-pdf -r asciidoctor-mathematical -D $(pwd) ./index.adoc

Writes following:

No such file or directory - notoserif-regular-subset.ttf not found in GEM_FONTS_DIR

mojavelinux · 2021-07-20T10:10:32Z

I'm not able to reproduce this problem in my own testing.

I am curious why you're using -D $(pwd) when calling asciidoctor-pdf. That's unnecessary given it's the directory you are already in.

mojavelinux · 2021-07-20T10:14:06Z

It's possible that in your environment, the file isn't readable for some reason. You could try to put a debug statement at the line in question inside the container and see if there is a reason it cannot find the file.

dduportal · 2021-07-20T10:14:13Z

That is weird, I cannot reproduce it at all. I suspect there is something related to the default user / UID of the shared volume.

I'll need the following element from you:

Output of docker info (to check if your Docker Engine is running in rootless mode or at least with usernamespacing enabled)
Result of docker run --rm --entrypoint=bash asciidoctor/docker-asciidoctor:1.8.0 -c "whoami && id -u" (to check the current behavior of the image that should be run as root user with UID 0)
Result of docker run --rm -v $(pwd):/data --entrypoint=bash asciidoctor/docker-asciidoctor:1.8.0 -c "ls -nd /data" (to check the current UID)
Result of docker run --rm --entrypoint=bash asciidoctor/docker-asciidoctor:1.8.0 -c "touch index.adoc && asciidoctor-pdf ./index.adoc" (to check if we can reproduce the error without involving any additional parameter)
Result of docker run --rm -v $(pwd):$(pwd) --entrypoint=bash asciidoctor/docker-asciidoctor:1.8.0 -c "touch index.adoc && asciidoctor-pdf ./index.adoc" (to check if we can reproduce the error with only 1 change at a time)
Result of docker run --rm -v $(pwd):$(pwd) -w $(pwd) --entrypoint=bash asciidoctor/docker-asciidoctor:1.8.0 -c "touch index.adoc && asciidoctor-pdf ./index.adoc" (to check if we can reproduce the error with only 1 change at a time)

mojavelinux · 2021-07-20T10:17:21Z

Actually, there is something even more fishy about this. You should never be seeing an error message that says "not found in GEM_FONTS_DIR". That value should be resolved to a concrete location. There has to be a reason it is not getting recognized.

Specifically, this line is not getting hit properly in your environment:

dir == 'GEM_FONTS_DIR' || dir.empty? ? ThemeLoader::FontsDir : dir

p- · 2021-07-20T11:33:49Z

Good news! (Sort of) I updated my local Docker before I saw @dduportal's new comment. My local Docker Engine/Server version is now 20.10.7. (Previously a recent Docker Engine 19.03.xy was in use.)

=> No issues with a recent Docker version.

Revert to Docker Desktop Community 2.5.0.1 (Docker Engine 19.03.13)

=> Now the issue occurs again.

So on another macOS-system I reverted back to following Docker version: Docker Desktop Community 2.5.0.1 (released on 2020-11-10)

@dduportal: here are the result for the non-working Docker-version:

@mojavelinux Yeah, that was a copy and paste oversight. (The reference to asciidoctor-mathematical is also not necessary)

=> So it seems to have a connection to the Docker version (it seems not to work with Docker Engine 19.03.xy) 🤔

dduportal · 2021-07-20T12:43:41Z

Thanks for the additional informations. I was able to reproduce on a stock Docker 19.03 by using "Docker in Docker":

Hi @dduportal
Thanks for analyzing it!

My colleague thinks, that it might be connected to this runc issue:
opencontainers/runc#2151

So this issue seems to stem from the Alpine Linux 3.14.0 Update:
https://wiki.alpinelinux.org/wiki/Release_Notes_for_Alpine_3.14.0

Use of the faccessat2 syscall has been enabled in musl. Due to runc issue 2151, new system calls incorrectly returned EPERM instead of ENOSYS when invoked under a Docker with libseccomp predating their release.

mojavelinux · 2021-07-20T19:51:26Z

I was able to reproduce on a stock Docker 19.03 by using "Docker in Docker":

Would you be able to check the line I referenced above and figure out why it is not being called? The program is clearly running, but for some reason it isn't executing that line. And I'm really curious to know why.

dduportal · 2021-07-27T14:31:42Z

@mojavelinux it looks like that the issue is related to the use of Alpine. Let me try on Debian and with the older version of Alpine (3.13) as well

p- · 2021-07-28T12:05:23Z

@dduportal As per my comment #214 (comment), we are pretty sure that it's connected to an improvement in Alpine Linux 3.14.0.

Use of the faccessat2 syscall has been enabled in musl. Due to runc issue 2151, new system calls incorrectly returned EPERM instead of ENOSYS when invoked under a Docker with libseccomp predating their release. Therefore, Alpine Linux 3.14 requires one of the following:

runc v1.0.0-rc93

Docker 20.10.0 (which contains moby commit a181391) or greater, AND libseccomp 2.4.4

I think the easiest fix for the moment is to downgrade the base image of docker-asciidoctor to Alpine Linux 3.13. until everyone had a chance to update their Docker versions. Alpine Linux 3.13 is supported until 2022-11-01.

I want to make clear that the issue does not lay with docker-asciidoctor itself. But I think downgrading the image would lead to less issues for the moment ;)

dduportal · 2021-07-28T12:26:17Z

@p- thanks for your diagnostic (and your colleague' ;) ). Your proposal sounds really good! Incoming PR :)

p- · 2021-07-28T12:35:52Z

@dduportal Thank you as well!

PS: I edited my comment above: every version of Alpine Linux that starts with 3.13. Should be ok. So you should be able to use 3.13.5 for example.
