In GDrive, filenames aren't unique, and directories are just
special files - so you can have multiple files with the same
name, multiple directories with the same name, and even files
with the same names as directories.
OC doesn't handle this at all, though, and just wants to act
as if file and directory names *are* unique. So when renaming,
we must check if there's an existing object with the same
file or directory name before we commit the rename, and
explicitly delete it if the rename is successful. (Other
providers like dropbox do the same for files, but intentionally
don't do it for directories; we really need to do it for
directories too.)
A good way to observe this is to run the storage unit tests
and look at the state of the Drive afterwards. Without this
commit, there will be several copies of all the test files
and directories. After this commit, there's just one of each.
We can't just say "hey, Drive lets us do this, what's the
problem?" because we don't handle multiple-objects, same-name
cases - getDriveFile() just bails and prints an error if it
searches for the file or directory with a given name and gets
multiple results.
Sometimes there are bugs that cause setupFS() to be called for
non-existing users. Instead of failing hard and breaking the instance,
this fix simply logs a warning.
ownCloud passes us a Unix time integer, but the GDrive API wants
an RFC3339-formatted date. Actually it wants a single particular
RFC3339 format, not just anything that complies will do - it
requires the fractions to be specified, though RFC3339 doesn't.
This resolves issue #11267 (and was also noted by PVince81 in
reviewing PR #6989).
This is a slightly hacky workaround for
https://github.com/google/google-api-php-client/issues/59 .
There's a bug in the Google library which makes it go nuts on
file uploads and transfer *way* too much data if compression is
enabled and it's using its own IO handler (not curl). Upstream
'fixed' this (by disabling compression) for one upload
mechanism, but not for the one we use. The bug doesn't seem to
happen if the google lib detects that curl is available and
decides to use it instead of its own handler. So, let's disable
compression, but only if it looks like the Google lib's check
for curl is going to fail.
Latest version with various bugfixes, also implements support
for using curl instead of its own io class when available; this
avoids the bug that causes severe excess bandwidth use due to
some kind of zlib issue.
This is the upstream commit that merged my query separator fix. It's slightly
after the 1.0.3-beta tag. I eyeballed the other post 1.0.3-beta changes and
none of them looks like any kind of problem, so we may as well just use this
upstream state.
