Store UUID in svn_fs_t rather than in FSAP_DATA. This is a cleaner

implementation of what r1330932 implements in a less robust manner.

Suggested by: gstein

(the particular 'cleaner implementation')

Update libsvn_fs:

* subversion/libsvn_fs/fs-loader.h

(fs_vtable_t.get_uuid): Remove this member, with comment.

(svn_fs_t.uuid): New struct member.

* subversion/libsvn_fs/fs-loader.c

(svn_fs_get_uuid): Track new location of UUID.

Update FSFS for the new location:

* subversion/libsvn_fs_fs/fs_fs.h,

subversion/libsvn_fs_fs/fs_fs.c:

(svn_fs_fs__get_uuid): Delete this function. It is subsumed into

svn_fs_fs__open() and svn_fs_fs__create().

* subversion/libsvn_fs_fs/caching.c

(svn_fs_fs__initialize_caches, svn_fs_fs__initialize_txn_caches):

* subversion/libsvn_fs_fs/fs.c

(fs_serialized_init):

* subversion/libsvn_fs_fs/fs_fs.c

(svn_fs_fs__open, hotcopy_incremental_check_preconditions,

hotcopy_incremental_check_preconditions, svn_fs_fs__set_uuid):

* subversion/libsvn_fs_fs/tree.c

(fs_same_p):

Track new location of UUID.

* subversion/libsvn_fs_fs/fs.c

(fs_vtable): Drop GET_UUID() member.

* subversion/libsvn_fs_fs/fs.h

(fs_fs_data_t.uuid): Remove this member.

Update BDB for the new location:

* subversion/libsvn_fs_base/fs.c

(populate_opened_fs): New function.

(base_create, base_upgrade): Call it to populate svn_fs_t->uuid.

* subversion/libsvn_fs_base/uuid.h

(svn_fs_base__get_uuid): Rename to..

(svn_fs_base__populate_uuid): .. this, and change signature.

* subversion/libsvn_fs_base/uuid.c

(svn_fs_base__get_uuid): Rename to..

(svn_fs_base__populate_uuid): .. this, and adapt to the new signature.

* subversion/libsvn_fs_base/tree.c

(fs_same_p):

(svn_fs_base__set_uuid):

Track new location of UUID.

* subversion/libsvn_fs_base/fs.c

(fs_vtable): Drop GET_UUID() member.

* subversion/libsvn_fs_base/fs.h

(base_fs_data_t.uuid): Remove this member.

Revert r1330932:

* subversion/libsvn_fs/fs-loader.c

(cache_uuid): Remove this function.

(svn_fs_open, svn_fs_create): Update callers.

(svn_fs_open_berkeley, svn_fs_create_berkeley): Update callers.

* subversion/libsvn_fs_util/fs-util.c

(svn_fs__identifier): Remove.

* subversion/include/private/svn_fs_util.h

(svn_fs__identifier): Reimplement as a macro. It will be removed in the

next revision.

Attempt to button down the BDB backend's memory usage by allowing trail

producers to tell that subsystem to discard all memory associated with

the trail.

Most of the time, this pool usage waste isn't a problem (because of

better pool practices in higher layers). But mod_dav and mod_dav_svn

have notoriously wicked pool usage behavior, and I'm tired of having

the theoretically niceties of our pool usage guidelines getting in the

way of Subversion working. Why should a simple 'svn ls -v' of a

directory with 10,000 files exhaust all the memory on my 2Gb laptop?

It shouldn't, ahd if this kind of change is what I have to do to get

that leakage back down to "only" 339Mb, I feel compelled to do it.

An arguably cleaner approach would have been to add a 'result_pool'

argument to the txn_body_* function type which is the same pool passed

to svn_fs_base__retry_txn(). That would allow the txn_body_*

functions (which already operate with 'trail' and 'trail->pool' today)

to use the 'result_pool' argument as a final destination for

returnable stuff and 'trail->pool' for scratch work. (And then

do_retry() function would, of course, always whack trail->pool when it

was finished with a trail.) I've filed issue #3395 to track this

possible future enhancement.

Combine two helper functions (one to check that a filesystem is

opened, one to check that it isn't) into a single one that does both

based on a boolean expectation flag.

NOTE: This changes the test when 'expect_open' is set to examine

svn_fs_t->fsap_data instead of svn_fs_t->path (since that's what

is checked when 'expect_open' is not set, too). I think that's

fine, but wanted to note that here anyway just in case it rings

some alarm in another developer's mind.

Commit upstream a CollabNet-maintained a patch against libsvn_fs*

which allows svn_fs_set_uuid() to accept a NULL argument which is

interpreted as "generate a new UUID". This is useful for

or depending on the undocumented ability of the filesystem layers to

Subject: Results of: [VOTE] New space-before-parens style

I took the opportunity to make spacing among all parens in SVN_ERR

macro calls consistent. But I did not address consistency of casts,

nor whether a function name should always appear below its return type

in declarations and definitions, nor whether there should be a space

before/after the "*" when declaring pointer return types.

Make all the libsvn_fs_base/bdb functions which currently accept only

trail_t's also accept (and use, instead of trail->pool) explicit 'pool'

parameters.

Callers of these functions which themselves live in the

libsvn_fs_base/bdb area now provide *their* new pool as the value for

this new parameter; callers outside that area pass trail->pool as that

parameter. The net affect, of course, is that no changes in memory

usage have happened at all. But this is the first step of several

incremental commits which should give us the flexibility over pool

usage that we need in the BDB backend.
