Zip archives with files having phrase `makefile' in name treat them as makefiles

[cieply]

I found this issue recently.
Zip archives with files having phrase `makefile' in name treat them as makefiles and upon enter mc tries to read paramaters for makefile and execute it.
I attached few samples.
Just try to enter/view them and you will see.

Even worse it is with compressed pdfs. They don't even need to use `.pdf' extension, they will be picked up anyway. Trying to view zipped pdf ends up with error window "Syntax Warning: May not be a PDF file (continuing anyway)" and one cannot view nor enter it. All one can do is to manually unzip it end then it can be read.
Example:

wget https://sun.aei.polsl.pl/~sdeor/corpus/reymont.bz2
bzip2 -dk reymont.bz2
zip reymont.zip reymont

These shouldn't work like that. One should be able to enter to zip archive and view it if they want, not to be treated like scripts.

I have checked that patch and it seems to work but I found analogical cases to those with .pdfs. Whenever you pack .pdf or .webm or .1/.2/.[0-9], or .jpg/.png/.gif/.bmp/.pnm/any image, same thing happens. I guess it has nothing to do with a suffix and everything with a recognized extension. Zip, rar, 7z, tar, whatever archive should not automatically execute any file in it in any case.

What do you mean exactly?

I said about pdfs in a first post. It happens with other extensions as well. If there is a file, with known suffix and is zipped then on enter it will be executed. It might make sens with .gz, .bz2, etc. but not with multi file archives like tar, zip, rar.

cp /usr/man/man1/cmp.1 cmp.1
zip m1.zip cmp.1

cp /usr/man/man1/cmp.1 cmp.1                                                                                                    cp /usr/man/man1/clear.1 clear.1                                                                                                  zip m2.zip cmp.1 clear.1

cp /usr/man/man1/cmp.1 cmp.1
cp /usr/man/man1/clear.1 clear.1
echo aaa > aaa.txt
echo zzz > zzz.txt
zip m3.zip cmp.1 clear.1 aaa.txt zzz.txt

Now you can't enter these archives. Instead they get "executed". what is executed? Some external, gui unarchiver in my case, which I don't necessarily want to use, using mc. You can't even view contents with F3. You get an error: <standard input>:2: warning: can't find character with input code 3

Same with files like pdfs, images, and so on.

zip img1.zip a.bmp

zip img2.zip a.bmp b.bmp

Sometimes if you add more files it stops doing that.

zip m5.zip /usr/man/man5/*

But in any way, it wasn't the case before.

Everything fine for me. I can enter to these archives.

In #4141 format of mc.ext was changed and mc.ext parser was rewritten. Such behaviour was fixed too.

Not for me though.

Well, there is only 4.8.28 available for ​download.
How can I fix it then?

BTW. if changes are so deep, why won't you call new version 4.9? Maybe keeping build count. That would be 4.9.29. Major version and then minor are more important than "build" or whatever you call the last number.

We will try to make a new release over the holidays. It's long due, but very unfortunately, I was not able to find time to support andrew_b so far. Had to deal with some unexpected infra migration in the time allocated for release instead.

It was a digression. I put it in right thread.

I wondered how to fix it, not when a new release is going to be.
I tried to compare diff with 4.8.16 but it didn't help me in finding it.

Wanted to bump this issue as version 4.8.30 still has this problem. Although constructions like 'blabla-makefile' are not a problem anymore, 'makefile' or 'makefile...blabla' are.

FN=Makefile
echo \# > $FN
zip $FN.zip $FN

FN=Makefile.blabla
echo \# > $FN
zip $FN.zip $FN

FN=makefile
echo \# > $FN
zip $FN.zip $FN

F3

Cannot open "/path/to/Makefile-1.zip" in parse mode
Operation not supported (95)

Also noticed that rar and 7z have no issue with these names.

rar a Makefile.rar Makefile
7z a Makefile.7z Makefile

Wonder whether it has something to do with uzip.

[andrew_b]

Makefile. makefile and Makefile.zip are handled with following section in mc.ext.ini:

    792 [Makefile]
    793 Regex=^[Mm]akefile
    794 Open=make -f %f %{Enter parameters}

Regex=^[Mm]akefile means that file name begins with Makefile or makefile. Makefile.zip is matched to that.

Fix is handle of Makefile as whole word:

Regex=^[Mm]akefile$

Makefile.zip isn't handled as zip-file because sections [zip-by-shell] and [zip-by-type] are below [Makefile].
