MercurialEclipse should not be case sensitive if OS is not case sensitive

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Rename a file with an external tool (e.g. from command line)
   Do not rename the file with "hg move".

What is the expected output? What do you see instead?
I expect that the file shows when opening Team >> Add.
This doesn't happen. And I cannot add the file with Eclipse.

What version of the product are you using? On what operating system?
- Mercurial version 2.2.1
- MercurialEclipse 1.9.4.201203270141
- Eclipse (epp.package.cpp 1.4.2.20120213-0813)
- Windows 7

Please provide any additional information below.

Eclipse might not know that file exists yet. Did you refresh your workspace? In 
navigator view select the folder you expect it to be in and press F5

Yes, I tried to refresh to workspace and also the folder it is in.
Also closing and opening the project doesn't work.

It's really easy to reproduce:

- Create a project and add a file
- Commit it to a repository
- Open Windows Explorer and change the name (in my case it's a name with a 
lower case character to upper case, e.g. vtresc.c to vtresC.c)
- After a refresh the icon repository_rep disappears.
- It is not possible to add the "new" file to the repository from eclipse.
- It lost track of the file, also changing the file and commiting again doesn't 
work.

The issue you're seeing is the case insensitive property of windows filesystems 
- Mercurial sees the renamed file as the old file.

One way to do a rename changing only the case of the filename:
- make a backup of the file
- delete the file
- commit the deletion
- restore the file from backup and give it the new name
- add and commit

Ok, but why is it then working ok under turtoiseHG or command line.

If you're seeing different result on the command line and in MercurialEclipse 
then right click on the project and select "Team -> Refresh Status". 
MercurialEclipse doesn't automatically refresh its status when doing things 
outside of Eclipse.

That doesn't work either.

What my problem is:
- We have an external tool that generates source from some resource files (text 
based resource files). These resource files are committed to the repository so 
we can regenerate the sources during build.
- Due to a change in the external tool it generates now files completely 
lowercase. Before it contained some uppercase characters (as said before).
- We cannot control the change of the generated file name case.
- We have old projects that contains uppercase characters and are committed to 
the repository. When continuing development it need to track the files.

What happens now:

- File is tracked and in sync with repository.
- Resource file is changed with external tool and after save the filename is 
completely lowercase.
- When running "hg status" on the command line (or "Add Files" from the 
turtoiseHG menu) it shows that the file is changed (marked with a 
questionmark). So the file is still tracked.
- In eclipse the icon repository_rep disappeared from the file icon.
- This is not changed with a workspace refresh, project refresh, folder 
refresh, "Team >> Refresh Status", eclipse restart, project close/open (this 
also refreshes the MercurialEclipse status).
- When running commit from the eclipse plugin the file doesn't show in the 
affected files (not as changed and also not as new). 
- It is not possible to add or commit the file anymore with the plugin.
- From inside eclipse with MercurialEclipse it's completely not noticeable that 
the file is not tracked anymore and the changes are not stored in the 
repository.

Are you sure the only difference is the case of the name? After changing only 
the case of a file name hg 2.2 command line status reports the file as clean. 
This should be the case in all other versions of mercurial on windows, unless 
there is a bug in older versions.

Are you sure the command line and hge are using the same version of hg? 

If there are other differences between hg command line and mercurial eclipse 
then it is because of Team Ignored Resources or because its an otherwise 
strange resource. 

Regardless of MercurialEclipse you have a tricky situation if you need the 
filenames to be the new case because Mercurial doesn't support renames 
differing only in case on operating systems with case insensitive file systems. 
You need to do something like I suggested in comment 3.

Yes, I'm sure that the only difference is the case of the name.
I tested it with only renaming the file in the windows explorer.

I have only one Mercurial version installed on my system (2.2.1). I can try to 
upgrade to the latest version.

When I only change the case of the filename hg status doesn't show the file (or 
at least not with the default options. When providing -c it shows the file as 
clean).
But directly the repository_rep icon disappears from the file in 
MercurialEclipse. So it lost track already there while the file is still marked 
as Clean.

I know that the situation is tricky, and for me it's not a problem because I 
use the combination of MercurialEclipse and the Commandline a lot.
But we have a lot of developers and a large project and codebase. And most of 
them are only using MercurialEclipse.

The problem has to do with the case inconsistency of the windows file system.

See 
http://hgbook.red-bean.com/read/file-names-and-pattern-matching.html#sec:names:c
ase for the information.

The problem is that Mercurial on windows is "Case preserving" and the 
MercurialEclipse plugin is (as far as I can see) "Case sensitive".

So when running "hg status" on a repository it shows that the file "test.c" is 
Clean, but in fact it's "Test.c". In MercurialEclipse the file cannot be found 
so it doesn't show the "repository_rep" icon on the file.

The same with adding. When running "hg add -n" the file doesn't show up in the 
list, so it will not be seen as "new" by the MercurialEclipse plugin.

Thanks for the explanation. It's definitely a bug.
