Latex-workshop: Saving imported files does not trigger build process

[mjohst]

Describe the bug
In Version 6.5.0 saving an imported subfile (\input{path/to/file}) does not trogger the build process anymore. Worked in Version 6.4.0.

To Reproduce
Steps to reproduce the behavior:

1. create your root.tex file
2. import another subfile.tex file in root.tex using \input{subfolder/subfile.tex}
3. change content of subfile.tex
4. build process is NOT started

Expected behavior
Up to version 6.4.0 saving the subfile.tex started the build process as changing and saving the root.tex file still does.

Logs
There are no logs created.

Desktop (please complete the following information):

• OS: macOS 10.12.6
• Extension version: 6.5.0

[acuarica]

I have the same behavior with version 6.5.0. The auto-build process worked fine in version 6.4.0 when saving included files (using input{...}).

Looking at the LaTeX Workshop output log, it seems that the included .tex files are not being watched.
However, when I modify a bibtex bibliography (.bib) file (using \bibliography{file.bib}), the auto-build process is triggered as expected.

Downgrading the extension to version 6.4.0 works as expected.

Desktop:
OS: macOS 10.13.6
Extension version: 6.5.0

[jlelong]

I cannot reproduce the issue. Can you please post the complete LW logs?

[acuarica]

I created a new test project. The main document is test.tex, which includes subdoc.tex.

test.tex

\documentclass{article}
\begin{document}
Test
\input{subdoc.tex}
\end{document}

subdoc.tex

Sub document.

I am experiencing this issue on Windows 10 too. No issues on 6.4.0, but the same project doesn't autobuild in 6.5.0.

[samquinan]

I was experiencing a similar problem (MacOS 10.14.4). I created a minimal working example with the intention of posting and then found this thread.

I checked and downgrading to 6.4.0 solved the problem; but, curiously, that solve seems to have persisted with the autoupdate back to 6.5.0? In any case, I'm back on 6.5.0 and I can no longer reproduce the issue... I've got no clue how to explain that given that I could faithfully reproduce the issue across three projects, cleaned aux files, and both application and system restarts during the preceding four hours.

During my testing earlier, my logs consistently included the line Cannot find file build/minimal.fls even though the file did in fact exist at the specified location (verified via the terminal). On saves, the logs simply stated:

[16:46:21] Found root file by magic comment: /Users/samquinan/Thesis/minimal/minimal.tex
[16:46:21] Root file remains unchanged from: /Users/samquinan/Thesis/minimal/minimal.tex.

(n.b., /Users/samquinan/Thesis/minimal is the project folder containing the root minimal.tex, a separate build folder for the aux files and a chapter folder containing the included .tex files that I was updating)

Given what I've read about the role the .fls file essentially containing the project's dependency graph in the Multi-File Project documentation, I figured the fact that the .fls file wasn't being found was likely related to the watcher not seeing the saves (I could manually run the build command from the subfile and everything built properly).

It looks like @acuarica's posted log contains a number of similar messages, though I don't have my full logs to compare... I figured it was worth posting what I had anyway, just in case, though.

[gmonet]

Same here on Windows 10 too.

[jlelong]

OK, I have managed to reproduce the issue, which is due to imported files not being watched anymore. I am trying to figure out how it has been broken.

[ashtez]

Thank you ! (Btw, same here on W10)

[jlelong]

It still needs some serious testing, in particular related to #1298. I hope to have properly and completely fixed the dependency manager.

[trevorgunn]

@jlelong I'm testing it now and there seems to be some regression from 6.5.0.

I've made some tests in a repository here. All of them work except the "Complicated Include" folder which has file A includes file B includes file B and some self-reference of B includes A and A includes B (through verbatim).

There's no issue with this with 6.5.0 however with the development version I get the following stack trace when I try the autobuild (and it doesn't build)

[jlelong]

Hum, I already have the issue in 6.5.0 and this is related to the structure analyser this time not the autobuild feature.

[trevorgunn]

@jlelong Yes, I can duplicate the issue with the structure analyser in 6.5.0 and the new version. However there is still an issue with clearTexFileTree which I have hopefully described well enough in #1341.

[jlelong]

I hope everything is fixed now. @trevorgunn thanks for your tests!

[jlelong]

@James-Yu I think everything has been fixed and we are ready for a new release.
