vcs-svn: drop string_pool

This reverts commit 1d73b52f5ba4184de6acf474f14668001304a10c
(Add string-specific memory pool, 2010-08-09).  Now that svn-fe
does not need to maintain a growing collection of strings (paths)
over a long period of time, the string_pool is not needed.

vcs-svn: pass paths through to fast-import

Now that there is no internal representation of the repo, it is not
necessary to tokenise paths.  Use strbuf instead and bypass
string_pool.

This means svn-fe can handle arbitrarily long paths (as long as a
strbuf can fit them), with arbitrarily many path components.

While at it, since we now treat paths in their entirety, only quote
when necessary.

Work around broken ln on solaris as used in t8006

The test setup in t8006-blame-textconv.sh uses "ln -sf" to
overwrite an existing symlink.  Unfortunately, both /usr/bin/ln
and /usr/xpg4/bin/ln on solaris 9 don't properly handle -f and -s
used at the same time.  This caused the test setup and subsequent

setup code.

13 years agostash: copy the index using --index-output instead of cp -p

stash: copy the index using --index-output instead of cp -p

'git stash create' must operate with a temporary index. For this purpose,
it used 'cp -p' to create a copy. -p is needed to preserve the timestamp
of the index file. Now Jakob Pfender reported a certain combination of
a Linux NFS client, OpenBSD NFS server, and cp implementation where this
operation failed.

Luckily, the first operation in git-stash after copying the index is to
call 'git read-tree'. Therefore, use --index-output instead of 'cp -p'
to write the copy of the index.

--index-output requires that the specified file is on the same volume as
the source index, so that the lock file can be rename()d. For this reason,
the name of the temporary index is constructed in a way different from the
other temporary files. The code path of 'stash -p' also needs a temporary
index, but we do not use the new name because it does not depend on the
same precondition as --index-output.

gitweb: highlight: replace tabs with spaces

vim ":set list" mode shows that the first character on each line is a
tab:

^I/*$

^I<span class="hl com">/*</span>$
<span class="hl com">^I * test</span>$
<span class="hl com">^I */</span>$

In gitweb, this winds up looking something like:

   1         /*
   2     * test
   3     */

I tried both Firefox and Opera and saw the same behavior.

The desired output is:

   1         /*

Note that the f245194 (diff: change semantics of "ignore whitespace"

from setting HAS_CHANGES when post-process filters that need to inspect
