library(pgfSweave) hangs on loadNamespace

[fgregg]

pgfSweave 1.1.1 R 2.12 x86_64 GNU/Linux

To reproduce: library(tikzDevice) library(cacheSweave) library(highlight) library(getopt)

debug(library)
library(pgfSweave)

the loadNamespace function call hangs within

 if (packageHasNamespace(package, which.lib.loc)) {
            tt <- try({
              ns <- loadNamespace(package, c(which.lib.loc, 
                lib.loc), keep.source = keep.source)
              dataPath <- file.path(which.lib.loc, package, 
                "data")
              env <- attachNamespace(ns, pos = pos, dataPath = dataPath, 
                deps)
            })

[cameronbracken]

I cannot reproduce this using R 2.12, pgfSweave 1.1.1 on my x86_64 Linux machine. Is there any other circumstances that cause the hang?

The namespace file for pgfSweave is fairly benign:

export("pgfSweaveDriver")
export("pgfSweave")

import(utils)
importFrom(digest, "digest")
importFrom(tools, "texi2dvi")

Could any of these things be causing it?

[fgregg]

hmm... not sure. Where are the export, import, and importFrom functions from, so I can test this?

[cameronbracken]

I dont actually know where you can access these functions, they are made available when loading a package namespace via loadNamespace. See:

http://cran.r-project.org/doc/manuals/R-exts.html#Package-name-spaces

Does

loadNamespace('pgfSweave') 

work?

[fgregg]

No, it hangs! Well, we are narrowing it down.

[fgregg]

The export, import, and importFrom functions seem to come from here: http://www.inside-r.org/r-doc/base/loadingNamespaceInfo

Not sure how to call them directly though, i.e.: namespaceExport("pgfSweave", "pgfSweaveDriver") Error in environmentIsLocked(ns) : not an environment

[cameronbracken]

I am really stumped now, I cant see what would be causing the hang on your machine in particular. Do you have anything in your .Rprofile that could be conflicting or any other special configuration?

[cameronbracken]

did you find the problem?

[fgregg]

No, I haven't. I'm pretty stumped too.

[fgregg]

I can send you the output of debug(loadNamespace) loadNamespace('pgfSweave')

[cameronbracken]

I was just wondering since you closed the issue, I have reopened it.

Sure, you can post the output.

Would it be possible for you to hack the NAMESPACE file in pgfSweave to take out lines, reload the package and try again? If not I can send you versions of the package with different lines taken out. This would help to narrow down things even more.

[Sharpie]

Hmm... I could not reproduce this one either---using Ubuntu 10.04, R 2.12.1 from CRAN Debian package and pgfSweave 1.1.2.

[fgregg]

Hmm.. so I hacked on the NAMESPACE file, for every combination, including an completely empty file, loadNamespace('pgfSweave') continues to hang.

I reinstalled pgfSweave and the install looks okay, but I post it here.

[cameronbracken]

Did you reinstall the version of the package that contains the edited namespace file? I may not have been clear in explaining, but I meant something like:

wget http://cran.r-project.org/src/contrib/pgfSweave_1.1.2.tar.gz
tar -xzf pgfSweave_1.1.2.tar.gz
cd pgfSweave
# edit NAMESPACE file in here
R CMD INSTALL .
# start R and try to load namespace...
# if it doesn't work, try a different combo in the NAMESPACE file,
# re-edit and try again

[fgregg]

No joy.

[cameronbracken]

hmm... What if you just remove the NAMESPACE file all together, then re-install the source package?

[fgregg]

I get an error that pgfSweave does not have a name space.

Perhaps the problem is not the loading of the actual NAMESPACE file but what is hooked on to .onLoad http://www.inside-r.org/r-doc/base/.onLoad

[cameronbracken]

Yeah, well it doesn't seem that one of the dependent packages is hanging so maybe it is the check for the correct version of pgf.

can you edit the R/zzz.R file and remove the line in the .onLoad function that calls checkPGFVersion2orDie()? Then reinstall/reload.

It may be that this check is hanging.

[fgregg]

That seems to have done it. Both loadNamespace('pgfSweave') and library(pgfSweave) work now.

[cameronbracken]

Alright! Now we are getting somewhere.

Can you kindly download the following file

https://github.com/downloads/cameronbracken/pgfSweave/checkPGFVersion2orDie.R

Then run the following commands in a fresh R session. My guess is that it will hang.

library(tikzDevice)
source("checkPGFVersion2orDie.R")
checkPGFVersion2orDie()

[fgregg]

so the problem seems to be that test-for-pgf.tex makes my pdflatex very unhappy. Here's a log file:

[cameronbracken]

Wow, thats nasty. I don't have the know-how to diagnose this but it seems there a problem with your pgf/xcolor installation. The test-for-pgf.tex file is literally 6 lines:

\documentclass{article}
\usepackage{tikz}
\batchmode
\makeatletter
\typeout{PGFVersion=\pgfversion}
\@@end

Can you load tikz in any other latex file?

[Sharpie]

\makeatletter
\typeout{PGFVersion=\pgfversion}
\@@end

It might be prudent to place the \typeout before the \makeatletter command. \makeatletter is only required to invoke \@@end (literally, "make @ a letter" so commands containing @ become valid and enabled)---while it is effect all sorts of things become "valid" LaTeX commands that maybe should not be.

[cameronbracken]

good call, maybe try compiling

\documentclass{article}
\usepackage{tikz}
\batchmode
\typeout{PGFVersion=\pgfversion}
\makeatletter
\@@end

[fgregg]

okay, I think the problem is that the pdflatex is loading the shared version of pgf.sty which is very old (ver 0.65) and not my local one. So one way you could test this with \usepackage{pgf} and looking at the log file for the version loaded

[fgregg]

Yup, that was it. Made some changes to the directory where my local version of pgf was installed, and everything works now. Thanks for your help!

[cameronbracken]

Awesome! Glad that got worked out.
