indeed unzip -v gives:
$ unzip -v text_simple.epub
Archive: text_simple.epub
Length Method Size Cmpr Date Time CRC-32 Name
-------- ------ ------- ---- ---------- ----- -------- ----
20 Defl:N 25 -25% 1980-00-00 00:00 2cab616f mimetype
which shows a size of 25 instead of 20 and a method as Defl:N instead of stored...
i've checked my call to zipOpenNewFileInZip -- which for simplicity was not supposed to ever compress a file -- and could figure out why in my example it says "Defl":
if (zipOpenNewFileInZip(file, filename.toUtf8().constData(), NULL, NULL, 0, NULL, 0, NULL, Z_DEFLATED, Z_NO_COMPRESSION) != Z_OK)
changed to a/ use the compression flag and b/ not use Z_DEFLATED when no compression is selected:
if (zipOpenNewFileInZip(file, filename.toUtf8().constData(), NULL, NULL, 0, NULL, 0, NULL, (compression ? Z_DEFLATED : 0), (compression ? 8 : Z_NO_COMPRESSION)) != Z_OK)
the warning wen away and
$ unzip -v text_simple.epub
Archive: text_simple.epub
Length Method Size Cmpr Date Time CRC-32 Name
-------- ------ ------- ---- ---------- ----- -------- ----
20 Stored 20 0% 1980-00-00 00:00 2cab616f mimetype
thanks for your help! your hints lead me to check the right thing!
i will commit the change before tomorrow if somebody wants to give a try...
ciao
