Bug ID: 5588
Summary: fsmonitor fails with "watchman command error: unable
to resolve root" on Windows MSYS environment
Product: Mercurial
Version: 4.2.1
Hardware: PC
OS: Windows
Status: UNCONFIRMED
Severity: feature
Priority: wish
Component: fsmonitor
Assignee: bugzi...@mercurial-scm.org
Reporter: rvandermeu...@mozilla.com
CC: gregory.sz...@gmail.com,

Hi, I maintain the MozillaBuild package that Mozilla distributes to provide a
build toolchain on Windows.
Our basic setup is as follows:
* MSYS toolchain (the original, not msys2)
* Python for Windows (version 2.7.13)
* Mercurial installed via pip (version 4.2.1)
I've recently been trying to test the native fsmonitor with the latest watchman
binary from upstream (rev 98b6d81 downloaded from the appveyor CI artifacts).
With watchman added to my path, I've confirmed that I can properly invoke it
from the command prompt:
$ watchman -v
4.9.0
However, when I set fsmonitor.mode = on, I get the following error whenever I
perform any operations:
warning: Watchman unavailable: watchman command error: unable to resolve root
c:\Users\Ryan\repos\mozilla-build: "c:\Users\Ryan\repos\mozilla-build" resolved
to "C:/Users/Ryan/repos/mozilla-build" but we were unable to examine
"c:\Users\Ryan\repos\mozilla-build" using strict case sensitive rules. Please
check each component of the path and make sure that that path exactly matches
the correct case of the files on your filesystem.
I've also checked and confirmed that the value of ui.slash has no bearing on
whether this error hits or not. I'd previously been able to use hgwatchman
(along with an older build of watchman) in this configuration, not entirely
bug-free, but it worked anyway, so this appears to be a regression somewhere
along the way.
If you'd like to download a test package the replicates the environment above,
it is available from the link below:
