Jeff King [Tue, 4 Nov 2014 13:24:53 +0000 (08:24 -0500)] 
ignore stale directories when checking reflog existence

When we update a ref, we have two rules for whether or not
we actually update the reflog:

  1. If the reflog already exists, we will always append to
     it.

  2. If log_all_ref_updates is set, we will create a new
     reflog file if necessary.

We do the existence check by trying to open the reflog file,
either with or without O_CREAT (depending on log_all_ref_updates).
If it fails, then we check errno to see what happened.

If we were not using O_CREAT and we got ENOENT, the file
doesn't exist, and we return success (there isn't a reflog
already, and we were not told to make a new one).

If we get EISDIR, then there is likely a stale directory
that needs to be removed (e.g., there used to be "foo/bar",
it was deleted, and the directory "foo" was left. Now we
want to create the ref "foo"). If O_CREAT is set, then we
catch this case, try to remove the directory, and retry our
open. So far so good.

But if we get EISDIR and O_CREAT is not set, then we treat
this as any other error, which is not right. Like ENOENT,
EISDIR is an indication that we do not have a reflog, and we
should silently return success (we were not told to create
it). Instead, the current code reports this as an error, and
we fail to update the ref at all.

Note that this is relatively unlikely to happen, as you
would have to have had reflogs turned on, and then later
turned them off (it could also happen due to a bug in fetch,
but that was fixed in the previous commit). However, it's
quite easy to fix: we just need to treat EISDIR like ENOENT
for the non-O_CREAT case, and silently return (note that
this early return means we can also simplify the O_CREAT
case).

Our new tests cover both cases (O_CREAT and non-O_CREAT).
The first one already worked, of course.

10 years agofetch: load all default config at startup
Jeff King [Tue, 4 Nov 2014 13:11:19 +0000 (08:11 -0500)] 
fetch: load all default config at startup

When we start the git-fetch program, we call git_config to
load all config, but our callback only processes the
fetch.prune option; we do not chain to git_default_config at
all.

This means that we may not load some core configuration
which will have an effect. For instance, we do not load
core.logAllRefUpdates, which impacts whether or not we
create reflogs in a bare repository.

Note that I said "may" above. It gets even more exciting. If
we have to transfer actual objects as part of the fetch,
then we call fetch_pack as part of the same process. That
function loads its own config, which does chain to
git_default_config, impacting global variables which are
used by the rest of fetch. But if the fetch is a pure ref
update (e.g., a new ref which is a copy of an old one), we
skip fetch_pack entirely. So we get inconsistent results
depending on whether or not we have actual objects to
transfer or not!

Let's just load the core config at the start of fetch, so we
know we have it (we may also load it again as part of
fetch_pack, but that's OK; it's designed to be idempotent).

Our tests check both cases (with and without a pack). We
also check similar behavior for push for good measure, but
it already works as expected.

10 years agocache-tree: avoid infinite loop on zero-entry tree
Jeff King [Wed, 29 Oct 2014 17:11:58 +0000 (13:11 -0400)] 
cache-tree: avoid infinite loop on zero-entry tree

The loop in cache-tree's update_one iterates over all the
entries in the index. For each one, we find the cache-tree
subtree which represents our path (creating it if
necessary), and then recurse into update_one again. The
return value we get is the number of index entries that
belonged in that subtree. So for example, with entries:

    a/one
    a/two
    b/one

We start by processing the first entry, "a/one".  We would
find the subtree for "a" and recurse into update_one. That
would then handle "a/one" and "a/two", and return the value
2. The parent function then skips past the 2 handled
entries, and we continue by processing "b/one".

If the recursed-into update_one ever returns 0, then we make
no forward progress in our loop. We would process "a/one"
over and over, infinitely.

This should not happen normally. Any subtree we create must
have at least one path in it (the one that we are
processing!). However, we may also reuse a cache-tree entry
we found in the on-disk index. For the same reason, this
should also never have zero entries. However, certain buggy
versions of libgit2 could produce such bogus cache-tree
records. The libgit2 bug has since been fixed, but it does
not hurt to protect ourselves against bogus input coming
from the on-disk data structures.

Note that this is not a die("BUG") or assert, because it is
not an internal bug, but rather a corrupted on-disk
structure. It's possible that we could even recover from it
(by throwing out the bogus cache-tree entry), but it is not
worth the effort; the important thing is that we report an
error instead of looping infinitely.

to allow different colors to be specified for matching strings in the

git-svn: disable _rev_list memoization

This memoization appears unneeded as the check_cherry_pick2 cache is

With this change applied, importing from local svn+ssh and http copies
of the R repo[1] takes only 2:00 (2 hours) on my system and the git-svn
process never uses more than 60MB RSS on my x86-64 GNU/Linux system[2].
This 60M measurement is only for the git-svn Perl process itself and
does not include memory used by git subprocesses accessing large packs
(subprocess memory usage _is_ measured by my time(1) tool).

Before this change, an import took longer (2:20) on svn+ssh:// but
git-svn used around 240MB during the imports.  Worse yet, git-svn
ballooned to over 400M when writing out the cache to the filesystem.

I also tried removing memoization for `has_no_changes', too, but a
local copy of the R repository(*) was not close to finishing within
10 hours on my system.

git-svn: reload RA every log-window-size

Despite attempting to use local memory pools everywhere we can,
(including our call to SVN::Ra::do_update and all subsequent reporter
calls), there does not appear to be a way to force the Git::SVN::Fetcher
callbacks to use a pool other than the per-SVN::Ra pool.
Git::SVN::Fetcher ends up using the main RA pool which grows
monotonically in size for the lifetime of the RA object.

Thus the only way to free that memory appears to be to destroy and
recreate the RA connection for at every --log-window-size interval.

This reduces memory usage over the course of fetching 10K revisions
using a test repository created with the script at the end of this
commit message.

As reported by time(1) on my x86-64 system:

before: 54024k
 after: 28680k

Unfortunately, there remains some yet-to-be-tracked-down slow memory
growth which would be evident as the `nr' parameter increases in
the repository generation script:
