When handing out node contents, the delta streams don't need

to calculate MD5 checksums as the result will not be used and the

check would be redundant even if it were made.

Thus, rev the svn_txdelta API to calculate the checksum only

upon specific request and update all callers to use the new API.

* subversion/include/svn_delta.h

(svn_txdelta2): declare new, extended API

(svn_txdelta): deprecate the old one

* subversion/libsvn_delta/text_delta.c

(txdelta_baton): extend docstring

(txdelta_md5_digest): handle the no-checksum-requested case

(svn_txdelta2): implement

(svn_txdelta): re-implement in terms of svn_txdelta2

* subversion/libsvn_fs_fs/fs_fs.c

(svn_fs_fs__get_file_delta_stream): eliminate duplicate MD5 calculation

* subversion/libsvn_ra/compat.c

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

Date: Wed, 8 Feb 2006 12:00:35 +0100 (CET)

Message-ID: <Pine.LNX.4.55.0602080918350.10805@localhost.localdomain>

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.

The txdelta stream's subpool wasn't used for anything beyond storing

itself and to "free" itself (i.e. it wasn't a parent of other subpools

or any other complicated pool logic). Instead, simply allocate the

stream in the provided pool and remove the "free" concept.

Per a suggestion from Greg Hudson <ghudson@MIT.EDU>, the BUILD_BATON

arguments in the delta construction functions were changed to an

explict type (rather than void *) for type safety.

* include/svn_delta.h (svn_txdelta_free): removed

* libsvn_wc_adm_crawler.c (do_apply_textdelta): remove call to

svn_txdelta_free().

* tests/libsvn_delta/vdelta-test.c (main): ditto.

* tests/libsvn_delta/svndiff-test.c (main): ditto.

* tests/libsvn_delta/random-test.c (random_test): ditto.

* libsvn_repos/delta.c (delta_files): ditto.

* libsvn_delta/delta.h (svn_txdelta__insert_op): change BUILD_BATON

argument to a 'struct build_ops_baton_t *' for type safety.

(svn_txdelta__vdelta): ditto.

* libsvn_delta/vdelta.c (vdelta): change BUILD_BATON argument to a

'struct build_ops_baton_t *' for type safety.

(svn_txdelta__vdelta): ditto.

* libsvn_delta/text_delta.c (struct svn_txdelta_stream_t): remove the

'pool' member.

(svn_txdelta__insert_op): change BUILD_BATON argument to a

'struct build_ops_baton_t *' for type safety.

(svn_txdelta): do not construct a subpool for the stream, but place

it directly into the provided pool.

(svn_txdelta_free): removed.

  1. … 8 more files in changeset.
Clarify the lifetime issues around the svn_txdelta_window_t

structure. In some cases, it was created as a "free standing" object

in its own subpool and svn_txdelta_free_window() needed to be

called. Other times, it was a structure on the stack.

Now, it is clearer that the code creating the window is responsible

for cleaning it, and how they clean it. If svn_txdelta_next_window()

is used, then it is passed a pool, so the caller knows to clear the

pool to toss the window. If the caller constructs a window manually,

then they also know how to clean it up.

NOTE: this change may also dramatically fix our memory consumption. I

found that the vdelta hash tables were allocated in the stream's pool,

rather than for each window. I'm not positive what the resulting peak

was, but it appeared to be on the order of a pointer for each byte in

the source *and* target files that were being diff'd. (e.g. compare

two one megabyte files and you'd get 8 megabytes of pointer data).

Basically, the wrong pool was passed to svn_txdelta__vdelta().

* include/svn_delta.h (svn_txdelta_window_t): Removed the 'pool'

member field.

(svn_txdelta_next_window): take a POOL argument. update doc.

(svn_txdelta_free_window): removed

* libsvn_fs/reps_strings.c (svn_fs__rep_deltify): allocate a subpool

* libsvn_delta/vdelta.c (vdelta): pass pool argument to the

svn_txdelta__insert_op() function for allocating space for the new

operation.

* libsvn_delta/svndiff.c (write_handler): allocate the window on the

stack, rather than on the heap. make the destruction of the

subpool explicit, rather than via svn_txdelta_free_window().

* libsvn_delta/text_delta.c (svn_txdelta__make_window): place the new

window directly into the pool passed, rather than into a new

subpool.

(svn_txdelta__insert_op): take a new POOL argument for allocations

related to the inserted operations.

(svn_txdelta_next_window): take a POOL argument for where to

allocate the new window (rather than via a subpool of the

stream->pool passed to make_window). create errors via this pool,

rather than the stream's pool. use this pool for computing vdeltas

instead of the stream pool(!!)

(svn_txdelta_free_window): remove

(svn_txdelta_send_string): remove assignment of the window's pool.

(svn_txdelta_send_txstream): use a subpool for storing the windows,

and clear on each iteration.

* libsvn_ra_dav/fetch.c (fetch_file_reader): remove assignment of the

window's pool.
