No fugitive commands working - temp file name problem or <SNR>52_ReplaceCmd issue?

[philwhiles]

Fugitive cloned from master today, installed with Pathogen, running with vim81 under cygwin on windows server 2012

Git installation is windows version, not cygwin - git works fine when invoked from bash.

:Glog, :Gstatus etc shows a disparity between the temp file name used in the !git command redirection and the subsequent output display, but this is always preceded by a complaint about 52_ReplaceCmd.

Is this a bug or a setup/env issue?

Those tempfiles are unrelated. The first is for running git log and the second is for displaying the first result. "Cannot open file" usually means "the command that was supposed to create this file failed". You'll have to crack open s:ReplaceCmd to see what went wrong. I don't have a way to test on Windows currently so I can't do much debugging myself.

I guess I can at least direct you to the line that's probably failing:

vim-fugitive/autoload/fugitive.vim

Line 2662 in 302f30c

call system('cmd /c "'.prefix.s:gsub(a:cmd,'[<>]', cmd_escape_char.'&').redir.'"')

I improved the error messages a bit which might provide a clue.

Pulled master - no better clues.
Sorry - don't do vimscript
The line you ref above appears not to be in master btw?

[tpope]

It's here now:

vim-fugitive/autoload/fugitive.vim

Line 2670 in 5ba918e

return system('cmd /c "'.prefix.s:gsub(a:cmd,'[<>]', cmd_escape_char.'&').redir.'"')

You could change that return system to echomsg to see what it's trying to run.

I have pushed some really good error messages.

If it's still happening, report back with the new error message.
