Unable to untar #6

Closed m2sarmadi closed 4 years ago

m2sarmadi commented 4 years ago

I have a .tar file that contains files with the following size(bit): 403,000 and 728 and 342,548 and 132,795 and etc. (most file formats are .js) It works fine when I start untaring it, but when it gets to a specific file it gives the following error : Could not open [fileName] for write And then the untaring of the rest of the files is also ignored. I am sure that this particular file is not a problem because it is untar alone in another sketch.

I can only think of a filesystem limitation here e.g. there's a 32 characters (path+filename) limit to FS.h, or the size of the tar + uncompressed content exceeds the partition size.

How many files are there in this tar archive and how deep is the folder structure in the tar ?

m2sarmadi commented 4 years ago

22 file are in tar archive and this files are in root of tar archive The total size of the tar aechive is 1.2 M.B Probably a problem with SPIFFS size

yup I just discovered there are many filesystem sizes in the SDK menu :sweat_smile:

@m2sarmadi did you get better results with smaller archives or should I keep this issue open as a bug ?

Since the WebServer component can serve gz contents, maybe minify+concat+gzip'ing your css/js/html files before creating the tar will work better ? (also using a css sprite image can decrease the amount of files)

bump

closing this as more relevant messages are now displayed when the filename exceeds 32 chars.

feel free to reopen if the symptoms are still there for you
