problem: fail to apply the patch

[chen.xi at telecom-bretagne.eu]

I went to the /patches/make directory and executed the make command as follows.

1) make setup, to create symbolic link and set guard. The last output is:
------------------------
# report what happened:
cd ../..; bash patches/make/each-patch-repo.sh 'hg qselect; hg qunapplied'
+ (cd sources/.; hg qselect; hg qunapplied)

------------------------

2) make check, I got errors, so I continued to do,

3) make force

4) make check, to review if the force command had been taken into effect. the output is:
------------------------
# check the difference betwen tip version and patch-required version, if there is difference,
# then create file current-diffs.txt in the source repo and exit with 1
# If this command fails, consider setting RELAX_CHECKS=true or FORCE_VERSIONS=true.
cd ../..; bash patches/make/each-patch-repo.sh \
        hg diff --git -I src -r "\$(bash `pwd`/patches/make/current-release.sh)" \
        "> current-diffs.txt;" \
        "if [ ! -s current-diffs.txt ]; then rm current-diffs.txt;" \
        "else grep '^diff' current-diffs.txt; exit 1; fi"
+ (cd sources/.; hg diff --git -I src -r $(bash /home/xc1427/continuation_research/davinci.v1/patches/make/current-release.sh) > current-diffs.txt; if [ ! -s current-diffs.txt ]; then rm current-diffs.txt; else grep '^diff' current-diffs.txt; exit 1; fi)
+ (cd sources/hotspot; hg diff --git -I src -r $(bash /home/xc1427/continuation_research/davinci.v1/patches/make/current-release.sh) > current-diffs.txt; if [ ! -s current-diffs.txt ]; then rm current-diffs.txt; else grep '^diff' current-diffs.txt; exit 1; fi)

------------------------

we can notice the strange message as "refers to unknow node XXXX". However, there is no more error.

5) make patch. This is where I failed. the output is:
------------------------
cd ../..; bash patches/make/each-patch-repo.sh \
        '(! hg qunapplied | read something) || hg qpush -a'
+ (cd sources/.; (! hg qunapplied | read something) || hg qpush -a)
+ (cd sources/hotspot; (! hg qunapplied | read something) || hg qpush -a)
+ (cd sources/jdk; (! hg qunapplied | read something) || hg qpush -a)
mq status file refers to unknown node f2029fe990b5
(working directory not at a head)
abort: working directory revision is not qtip
*** Exit status 255.
+ (cd sources/langtools; (! hg qunapplied | read something) || hg qpush -a)
make: *** [mq-push-patches] Error 255
------------------------

As we see, the error comes out as "working directory revision is not qtip". I searched in google and mercurial wiki, but found few helpful informations.

== My point of view ==
I've ever tried "hg qapplied" in the sources/hotspot right after the first step. I got supprised by the output:
----------
mac-tweaks.patch
meth.patch
coro-meth.patch
coro.patch
----------
which means some patches had been applied before I did nothing. And recall the previous strange message "refers to unknow node XXXX".

I got frustrated at the very first stage. Can somebody help me?
