[yocto] fetch from perforce

[Katu Txakur]

Thanks for your answer Paul,

it took me longer than I thought because I couldn't find any documentation
or comments in the code, but I finally got this working. The sintax to call
it was, (there are actually 2 options, I took this one because I don't need
user/passwd):


P4PORT = "yourhost:yourportnumber"
FETCHCOMMAND_p4 = "p4"

SRC_URI = " \
p4://depot/myproject...;module=destinationfolderInWORKDIR/destinationsubfolder;changeslist=9952
\
"

I used the perforce.py in the latest yocto distribution, 1.5-dora. The
subfolders where being renamed wrongly, deleting the first 3 characters. I
solved it using this patch:

diff --git poky/bitbake/lib/bb/fetch2/perforce.py_dora
poky/bitbake/lib/bb/fetch2/perforce.py
index fc4074d..d2ecccc 100644
--- poky/bitbake/lib/bb/fetch2/perforce.py_dora
+++ poky/bitbake/lib/bb/fetch2/perforce.py
@@ -112,7 +112,7 @@ class Perforce(FetchMethod):
         base = path
         which = path.find('/...')
         if which != -1:
-            base = path[:which]
+            base = path[:which-1]

         base = self._strip_leading_slashes(base)

I hope this helps to anyone trying to use this.

Cheers,
Katu
