Autobuild fails in subfolders in 8.7.0+

[jmussman]

Preliminary questions [Required]

Disable all the other extensions except for LaTeX Workshop, and check that you still see this issue. [Required]

You still see this issue?: Yes, and all other extensions have been left disabled during testing.

Make sure to visit the wiki FAQ before filling an issue.

You visited the wiki?: Yes

If your issue is with compiling a document (not having to do with finding the root file of a project), check first that you can compile manually.

You can compile a TeX document manually?: Yes

Describe the bug [Required]

On my computer a build will not automatically run when a file in a subfolder is saved. It does work for the master document in the root folder. This happens on any version from 8.7.0 forward. I've checked 8.5.0 and 8.6.0 on my computer and they work properly. The build folder is never created. latex-workshop.latex.autoBuild.run is set to onFileChanged. The file is on the local disk. I've tried setting latex-workshop.latex.watch.usePolling to true, no effect. latex-workshop.latex.search.rootFiles.include is set to the default of **/*.tex. latex-workshop.latex.rootFile.useSubFile is set to true. latex-workshop.latex.rootFile.doNotPrompt is set to true (applies to 8.7.2 only of course).

To Reproduce

Steps to reproduce the behavior:

1. Make sure the -cd option is added to the latexmk recipe.
2. Start with my template project: https://github.com/nextstepitt/standard-course-template.
3. Open Workbook/01_Rename_Me/section-0.tex.
4. Change and save the file.

Expected behavior

I expect a subfile with a .tex extension to be compiled when the file is saved.

Additional context

I would be the first to suspect that I have missed something about a new setting or change in 8.7.0 but I have been over and over the ones I see related to the watcher and subfiles and I haven't found it even after experimenting with changes. My apologies if I did miss something :(

Is there any chance this is related to the change made after #1895? It does not seem likely because it commences with 8.7.0, but it is clearly a subfolder issue. Please note in the log that a watcher is never created for section-0.tex even though it is opened, changed, and saved!

[jlelong]

This is related to #1972.

As explained in the wiki, we use two strategies to discover all included files

1. the rootFile is parsed to discover all the files it includes using input, include, InputIfFileExists, subfile, import and subimport and the process goes on recursively. Unfortunately, this does not work when the included file name contains a TeX macro. Hence, the second approach
2. When a .fls file with the same basename as the root file exists, it is used to compute the full list of dependencies. This file is produced by pdflatex thanks to the -recorder option automatically parsed by latexmk.

As noted in #1972, there was an error in the path resolution of files listed in rootFile.fls, hence the issue.
