bug#19817: 24.4; cmdproxy fails on some .exe when given a path argument

[Fabio Leimgruber]

To reproduce, first copy `C:\Windows\System32\write.exe' to
`C:\Windows\System32\write.test.exe'.  Then from a Command Prompt
(i.e. cmd.exe, I will use `$' for distinction nonetheless):

$ cd D:\opt\emacs\libexec\emacs\24.4\x86_64-w64-mingw32

$ cmdproxy.exe -c "\"write\" \"d:/asdf.txt\""

works, whereas:

$ cmdproxy.exe -c "\"write.test\" \"d:/asdf.txt\""

fails with:

'write.test" "d:' is not recognized as an internal or external command,
operable program or batch file.

Additional information:

when doing the more explicit:

$ cmdproxy.exe -c "\"write.test.exe\" \"d:/asdf.txt\""

WordPad starts.  FWIW, without the argument, the call:

$ cmdproxy.exe -c "\"write.test.exe\""

succeeds as well.  This came to attention when I tried to call
`py.test.exe' via `cmdproxy.exe', see [1].

You are not supposed to invoke cmdproxy directly, only via Emacs
functions that invoke shell commands.  So please show a test case
which works with "write" or "write.exe" or "write.test.exe", but fails
with "write.test".

Also, why are you quoting file names that don't require any quotes?

I meant a test case that tries to invoke these via Emacs functions.

Thanks, I will look into this.

One question, though: which executable programs should exist in the
current directory for this test case to reproduce the problem?  Is the
answer write.exe and write.test.exe?  (I'm asking because the original
use case seemed to involve a batch file as well, which complicates
things quite a lot.)

Thanks for looking into this.

Regarding the executables: originally, this came to attention when we
tried to call a py.test.exe (installed via Python package manager) from
the testing machinery of elpy [1] - i.e. no batch files.  AFAICS, the
problem occurs with any .exe that is renamed so that the file name
contains a second dot.  I chose write.exe (and a copy renamed to
write.test.exe) from C:\Windows\System32 for a reproducible example
because it is already on %PATH% and most likely present on a standard
Windows system.

There were a few issues in cmdproxy wrt this scenario.  I fixed them
on the emacs-24 branch, please take a look.

Thanks, I'm therefore closing this bug.
