I recently get spurious "file errors" when building master. The first one
is from Windows XP and goes as
>>Error occurred processing ../../lisp/gnus/gnus-group.el: File error (("Renaming" "Permission denied" "c:/emacs-git/trunk/lisp/gnus/gnus-group.elc2552Dme" "c:/emacs-git/trunk/lisp/gnus/gnus-group.elc"))
That file still has its extension .elc2552Dme.
The second one is from Debian and goes as
Error running git rev-parse: (file-error "Searching for program" "No such file or directory" "git")
Any ideas?
Thanks, martin

I don't observe this on Ubuntu 16.04. When are you seeing this? autogen.sh?
gitlog-to-changelog? emacs-repository-version-git?
I assume you have git installed; is it on a network directory that is flaky, or
perhaps something is setting PATH to a value that does not include the directory
where git is?

git is on my machine in usr/bin and PATH includes usr/bin. I'm using
git all the time without problems.

I'd suggest to instrument the place where this happens to display the
value of exec-path.

In emacs-repository-version-git, I guess: that's where the "Waiting
for git" message is coming from.
My crystal ball says exec-path will come out nil, btw.

So it's bug#20799, allright. Hmm...
I'm not sure I understand why we invoke Git in this case: the
source-directory is known and used by emacs-repository-get-version, so
why cannot it do the same it does for an in-tree build, i.e. access
the files in .git/ directly, just relative to source-directory? What
am I missing?

Yes, that's how it works for me. If I try the attached debugging patch, 'make'
chatters as follows:
Loading leim/leim-list.el (source)...
emacs-repository--version-git-1
/home/eggert/src/gnu/emacs/static-checking/.git/HEAD
/home/eggert/src/gnu/emacs/static-checking/.git

/home/eggert/src/gnu/emacs/static-checking/.git/refs/heads/master
/home/eggert/src/gnu/emacs/static-checking/.git
Finding pointers to doc strings...
Finding pointers to doc strings...done
which is what I'd expect: git does not get executed. Martin, can you investigate
why git is executed in your case?

I have some 10 separate sub-directories in my emacs directories each for
the builds of the corresponding toolkit (Gtk, lucid, motif, ...). These
are not tracked by git. Could that be the cause? The messages printed
by your patch are:
emacs-repository--version-git-1 /home/martin/emacs-git/release/.git/HEAD /home/martin/emacs-git/release/.git
emacs-repository--version-git-1 /home/martin/emacs-git/release/.git/refs/heads/master /home/martin/emacs-git/release/.git

I don't see why it would: what matters is the source-directory, and
that is the same for all of those build sub-directories, right?

It's the same source-directory for all of them, yes.

The directories and files exist and can be read if it's that what you
mean.

So -- adding calls to 'message' fixes the bug?!?
I'm afraid you will have to debug this more directly; I don't see how to do more
from a distance than I already have.

Silly me. Obviously not!!

I was confused and applied your patch and tested it on the emacs 25
branch where the problem does _not_ happen. Please disregard all my
prior messages where the word "release" appears in a path or file name.
Sorry.
On master I'm getting with your latest version.patch:

Aha! That's it.
I guess you've garbage-collected your repository, either by hand ('git
gc') or automatically, and that there is a file .git/packed-refs that
contains a line like this:
8e22067d59f59ee3a39f5d4f95c27e8ea3c935d6 refs/heads/master
If so, someone (perhaps you?) needs to modify the
emacs-repository-get-version function in lisp/version.el to handle this
situation.

Not by hand but during a pull git told me something about doing some
collection or packing.

There is such a file and the number shown on that line is that returned
by ‘emacs-repository-get-version’.

On Windows I have done manual packing frequently and the ../heads
directory is not empty. And on GNU/Linux if I manually call
‘emacs-repository-get-version’ it does return the number of packed-refs.
Queer.

OK, thanks, I installed something into master which should work for your
setup.
This area is a house of cards if you ask me (Emacs should not be fooling
around with Git internals!) but I didn't attack the larger problem.

IIUC you nevertheless did that in the meantime. But it seems that I
can't test any fix because git now seems to have populated
/home/martin/emacs-git/quick/.git/refs/heads again. Maybe that
directory is empty only following an (automatic?) GC until the next
pull. I will try to watch the behavior of git in this regard in the
future.
Thanks again for your efforts, martin

You cannot have automatic GC enabled on Windows, IME, since then a
pull will typically fail due to file sharing violations.

Because when you call it manually, exec-path is already set, so the
Git invocation works.

Ah, this appears to be Bug#20799. It's odd that you run into it while I
do not. I wonder why that would be? For what it's worth I'm running in a
full clone, where "git diff" reports no differences.

Hmm.... I thought bug#20799 was Windows-only. And I don't see this on
Windows but only on Debian.
I'm not sure whether mine was a full clone or had changes. I'll tell
you the next time this happens,

Having a temporary file with such an extension is normal, you can see
that in the code.
Do you have anti-virus software installed on that machine, and if so,
did you lately change it configuration or upgraded to a different
version?
