Here is the final solution to the issue, I suggest the file_blob_storage
modification and renaming the existing files for everyone, it's extremely
clumsy to utilize special characters in file names (macos seems to handle
"/" in the file name, don't know why "/" is used instead of ":" as windows,
the modification renames the file name, existing urls and references keep
working, yet a refactoring is needed for the files themselves)
*file_blob_storage.py modification*
def _FileForBlob(self, blob_key):
blob_key = self._BlobKey(blob_key)
return os.path.join(self._DirectoryForBlob(blob_key),
str(blob_key)[1:].replace("/",";").replace(":",";"))
This ensures that files have ";" instead of "/" or ":"
*To pull out the special files from the windows SDK*
1) Go to blob_image.py's serve_image function and pass/comment out
the datastore.Get(key) check (because we're going to ping files from the
serving url scheme, this ensures every file is served from that url scheme)
2) Modify file_blob_storage.py to copy the accessed files to a new location
(from the old SDK)
def _FileForBlob(self, blob_key):
blob_key = self._BlobKey(blob_key); handle=False
path=os.path.join(self._DirectoryForBlob(blob_key), str(blob_key)[1:])
if path.find("ncoded")!=-1: handle=True
if handle and not kaan_marked.get(blob_key):
logging.info("YEY %s"%blob_key)
kaan_marked[blob_key]=True
blob_file = self._FileForBlob(blob_key)
input = _local_open(blob_file, 'rb')
output= _local_open("C:/GCS/"+str(blob_key)[1:].replace(":",";")
,'wb')
try:
while True:
block = input.read(1 << 20)
if not block:
break
output.write(block)
finally:
output.close()
logging.info(path)
return os.path.join(self._DirectoryForBlob(blob_key), str(blob_key)[1:])
3) Ping each image, I decided to ping them by browsing the
"__GsFileInfo__"'s from the Datastore VIewer, couldn't access them easily
programatically
gg=document.getElementsByTagName("td"); for(var i=0;i<gg.length;i++)
if(gg[i].innerHTML.indexOf("ncoded")!=-1) { var image =
document.createElement("img"); image.src =
"http://localhost/_ah/img/"+gg[i].innerHTML.trim();
document.body.appendChild(image); }
Then put the images back to the old or new "n" folder
I think all windows SDK users should do this, I don't know how macos
handles "/" in the filenames, yet I would suggest everyone to fix the file
access manually
I've added this to my list of manual sdk modifications, currently I have 9
manual modifications, sad ... :)
