git-cache-proxy: Periodically run `git gc --quiet'
git has a feature which is supposed to automatically run git gc.
But if your repository accumulates enough loose objects, then this
occurs:
$ git gc --auto
Auto packing the repository in background for optimum performance.
See "git help gc" for manual housekeeping.
error: The last gc run reported the following. Please correct the root cause
and remove gc.log.
Automatic cleanup will not be performed until the file is removed.
warning: There are too many unreachable loose objects; run 'git prune' to remove them.
Removing $GIT_DIR/gc.log generally simply causes git gc --auto to
print, again, the message:
warning: There are too many unreachable loose objects; run 'git prune' to remove them.
Ie, a repository can get into a state where it needs gc so badly that
git will not gc it automatically. This is, of course, mad. It seems
to have been a misguided attempt at a safety catch. Unfortunately
there does not even appear to be a configuration knob to set this `too
many' limit to infinity.
Work around this problem by running `git gc --quiet' (every 10 days,
by default). This is not ideal because it runs even if we haven't
updated the tree, but we would rather do it out of housekeeping rather
than in the middle of fetch/clone.
`git gc' without --auto does not refuse to prune the objects that need
pruning, and fixes the repository.
We leave the gc.auto config option enabled since I think it is largely
harmless, and disabling it would be extra work.

fishdescriptor: cast __errno_location correctly
The return value from __errno_location() is an int*. My syntax had
erroneously specified that it returned an int. Nothing spotted this
bug because the expression is evaluated by gdb whose C interpreter is
very strange. In particular, gdb lets you dereference an int, even on
a platform where ints are 32-bit and pointers are 64-bit.
If you are on a 32-bit platform, this does not matter. Likewise if
you are on a 64-bit platform and the address of errno happens, by
luck, to be within the 32-bit addressable part of the space.
If you are mildly lucky the result of this is an error like this:
gdb.MemoryError: Cannot access memory at address 0x2f24ef10
buried in stack traces from fishdescriptor.
If you are unlucky, fishdescriptor will successfully access some wrong
location. This means it does not actually save and restore errno,
since it saves and restores somewhere else instead. So fishdescriptor
will corrupt the errno value of the thread that it happens to
be (ab)using, overwriting it with the errno from fishdescriptor's own
calls, possibly causing the target program to become confused about
the error(s) from system call(s) it is making.
If you are very unlucky, fishdescriptor will successfully access some
wrong location which is actively in use by something outside the
target process (eg, direct IO, shared memory0. fishdescriptor will
save the value (a single int) and then restore it a bit later. This
might in principle cause any kind of arbitrary lossage.
