Hi,
Any news on this issue?
Just as a FYI: in SVN we're getting close to starting the release
train on 1.14.1. Would be nice for our Windows users to be able to
include a 1.7.x APR with this issue fixed ;-).
(Of course I know I don't get to dictate any project's release
schedule, not to mention anyone's time spent on an issue -- I know I'm
not doing the work here ... just consider this some meta-data in case
it matters :-))

Yay! Thanks all for your efforts in fixing and backporting this!
I can't test this anytime soon (but will get around to it eventually).
In the meantime I've left a short message on the tortoisesvn-users and
the svn-dev mailinglists where this issue was brought up.

Bringing this from APR's list back to dev@s.a.o... For those affected
by issues with working copies on 'subst' drives on Windows (as
reported in mails such as [1], [2]) the following should come as
welcome news:

If possible I encourage to help with test and review. With any luck
hopefully SVN binary providers on Windows will be able to have this
issue fixed with the next release.

Hi,
The problem with apr_stat(APR_FINFO_LINK | APR_FINFO_MIN) should be
fixed by r1896717 [1] in trunk.
This fix also should resolve performance regression in apr_stat()
in most common cases.
I plan to backport this fix to APR 1.7.x at some point later.
Testing and review will be much appreciated! :)

Thanks for looking into this, Mariusz.
I think you might be onto something. I intended to look closer into
your diagnosis, and perhaps try to test if changing those lines back
to the original would fix it. But I didn't get around to it, sorry.
Now that there was talk of an APR 1.7.1 release on this list, it
popped back into my memory :-).
@apr devs: what do you think about Mariusz pointer towards the
possible cause of what we're seeing with SVN on Windows with apr
1.7.0? And is there an easy fix (for instance, just reverting that
single hunk), which has a chance of being accepted into 1.7.1 (if so,
I'll try to test it on my svn-dev machine, where I could reproduce the
issue)? IIUC, right now apr_stat does seem to error out on paths
ending with "/" or "\" on Windows, if APR_FINFO_LINK is given (while
APR 1.6 did return a sensible result in that case).
To be clear, IIUC Mariusz is referring to this hunk in filestat.c in r1855950:
[[[

Hi,
Maybe problem is in this line 627 in filestat.c [1] (changed in revision [2]) mainly by adding APR_FINFO_LINK in line 627
Diff to prev: [3]
I think that this change is causing that "if" branch is not executed (svn is using APR_FINFO_LINK in call) and in "else" branch we get error from FindFirstFileW [6] because root (e.g. after subst) is ending with "/" or "\" as in example from [4])
The error code 720002 from apr_stat means ERROR_FILE_NOT_FOUND (code 2 (0x2) [5]) from FindFirstFileW plus some adding and multiplication operations in apr layer (last digit in 720002 is code 2).

Hi again,
Is there any news on this issue? We're getting pretty close to rolling
SVN 1.14.1 (probably end of this week, then we need a week of testing
and signing, during which I might be able to test with a new version
of APR 1.7, if there would be one). Of course, it's not the end of the
world if this wouldn't be included, but it would be nice to have.
Thanks,

Yes, thanks, and no problem. I think that might be just in time, so
I'm crossing my fingers :-).
(as you might know, Subversion development is going quite slowly these
days, so it's hard to say when the cycles of the different volunteers
will align -- it might be end of this year still, but I'm guessing
it's more likely to be early January too I think ... we're progressing

Sorry, I'd been pounding on a beta deliverable, it's my bad. This coming
week I have cycles to give
back to APR, CMake and other projects neglected during this crunch period.
I hope an end-of-year
(or very early January) release will meet your goals..
