There was confusion in different parts of the progress bar code about
whether an update contained the total number of bytes transferred, or the
number of bytes transferred since the last update. One way this bug
showed up was progress bars that seemed to stick at zero for a long time.
In order to fix it comprehensively, I add a new BytesProcessed data type,
that is explicitly a total quantity of bytes, not a delta.
Note that this doesn't necessarily fix every problem with progress bars.
Particularly, buffering can now cause progress bars to seem to run ahead
of transfers, reaching 100% when data is still being uploaded.
When a page is loaded, the javascript requests an notification url, and
does long polling on the url to be informed of changes. But if a change
occured before the notification url was requested, it would not be notified
of that change, and so the page display would not update.
I fixed this by *always* updating the page display after it gets
the notification url. This is extra work, but the overhead is not noticable
in the other overhead of loading a page.
(A nicer way would be to somehow record the version of a page initially
loaded, and then compare it with the current version when getting the
notification url, and only force an update if it's changed. But getting
the "version" of the different parts of the page that use long polling
is difficult.)
There are two types of equality here, and which one is right varies,
so this forces me to consider and choose between them.
Based on this, I learned that the commit in git anex sync was
always doing a strong comparison, even when in a repository where
the inodes had changed. Fixed that.
* addurl: Escape invalid characters in urls, rather than failing to
use an invalid url.
* addurl: Properly handle url-escaped characters in file:// urls.
This fixes the issue mentioned in the last commit.
Turns out just collecting UUID of clients behind a XMPP remote is
insufficient (although I should probably still do it for other reasons),
because a single remote repo might be connected via both XMPP and local
pairing. So a way is needed to know when a push was received from any
client using a given XMPP remote over XMPP, as opposed to via ssh.
This cannot completely guard against a runaway log event, and only runs
every hour anyway, but it should avoid most problems with very
long-running, active assistants using up too much space.
The only thing lost is ./ghci
Speed: make fast used to take 20 seconds here, when rebuilding from
touching Command/Unused.hs. With cabal, it's 29 seconds.
In general, git-annex does not try to preserve file permissions. For
example, they don't round trip through special remotes. So it's ok to not
preserve them for git remotes either.
On crippled filesystems, rsync has been observed failing after the file
was transferred because it couldn't set some permission or other.
This is so gratutious and pointless. It's a shame that everything we
learned about Unix portability and the importance of standards has been
thrown out the window by these guys.
Various things that don't work on Android are just ifdefed out.
* the webapp (needs template haskell for arm)
* --include and --exclude globbing (needs libpcre, which is not ported;
probably I'll make it use the pure haskell glob library instead)
* annex.diskreserve checking (missing sys/statvfs.h)
* timestamp preservation support (yawn)
* S3
* WebDAV
* XMPP
The resulting 17mb binary has been tested on Android, and it is able to,
at least, print its usage message.
It used to not log to daemon.log when a repository was first created, and
when starting the webapp. Now both do. Redirecting stdout and stderr to the
log is tricky when starting the webapp, because the web browser may want to
communicate with the user. (Either a console web browser, or web.browser = echo)
This is handled by restoring the original fds when running the browser.
since some systems may have configuration problems or other issues that
prevent web browsers from connecting to the right localhost IP for the
webapp.
Tested on both ipv4 and ipv6 localhost. Url for the latter looks like:
http://[::1]:50676
