Convert from mercurial to Mercurial two times

[Ithier de Lestrange]

Hi,

I have a project that depends on a library. Both are Mercurial 
repositories. Recently I had to transfert files from the project to the 
library while keeping the history of the files.

The solution that I found was to use the convert extension with a 
filemap parameter to specify the files to transfert. This work great the 
first time, but then I had to transfert another file and it doesn't work 
anymore.

Here is a complete example to reproduce the problem:


Create first repository and add two files
C:\Travail\hgtmp>hg init first
C:\Travail\hgtmp>cd first
C:\Travail\hgtmp\first>echo some text  1>file1.txt
C:\Travail\hgtmp\first>echo some other text  1>file2.txt
C:\Travail\hgtmp\first>hg commit -A -m "two files in first repo"
adding de file1.txt
adding de file2.txt

C:\Travail\hgtmp\first>cd..

Create second repository, activate convert extension and add a file
C:\Travail\hgtmp>hg init second
C:\Travail\hgtmp>cd second
C:\Travail\hgtmp\second>echo [extensions]  1>.hg\hgrc
C:\Travail\hgtmp\second>echo convert =   1>>.hg\hgrc
C:\Travail\hgtmp\second>echo some more text  1>file3.txt
C:\Travail\hgtmp\second>hg commit -A -m "one file in second repo"
adding de file3.txt

Transfert file1.txt
C:\Travail\hgtmp\second>echo include file1.txt  1>import1
C:\Travail\hgtmp\second>hg convert --filemap import1 ../first .

0 two files in first repo

C:\Travail\hgtmp\second>hg merge
1 files updated, 0 files merged, 0 files removed, 0 files unresolved
(branch merge, don't forget to commit)

C:\Travail\hgtmp\second>hg commit -m "transfert first file from first repo"


Transfert file2.txt
C:\Travail\hgtmp\second>echo include file2.txt  1>import2
C:\Travail\hgtmp\second>hg convert --filemap import2 ../first .
scanning source...

converting...

C:\Travail\hgtmp\second>hg merge
abandoné: there is nothing to merge


As you can see, the second transfert does nothing and so the merge has 
nothing to do.

What am I doing wrong ?

Thanks
