We set "use warnings" in most of our perl code to catch problems. But as
the name implies, warnings just emit a message to stderr and don't
otherwise affect the program. So our tests are quite likely to miss that
warnings are being spewed, as most of them do not look at stderr.
We could ask perl to make all warnings fatal, but this is likely
annoying for non-developers, who would rather have a running program
with a warning than something that refuses to work at all.
So instead, let's teach the perl code to respect an environment variable
(GIT_PERL_FATAL_WARNINGS) to increase the severity of the warnings. This
can be set for day-to-day running if people want to be really pedantic,
but the primary use is to trigger it within the test suite.
We could also trigger that for every test run, but likewise even the
tests failing may be annoying to distro builders, etc (just as -Werror
would be for compiling C code). So we'll tie it to a special test-mode
variable (GIT_TEST_PERL_FATAL_WARNINGS) that can be set in the
environment or as a Makefile knob, and we'll automatically turn the knob
when DEVELOPER=1 is set. That should give developers and CI the more
careful view without disrupting normal users or packagers.
Note that the mapping from the GIT_TEST_* form to the GIT_* form in
test-lib.sh is necessary even if they had the same name: the perl
scripts need it to be normalized to a perl truth value, and we also have
to make sure it's exported (we might have gotten it from the
environment, but we might also have gotten it from GIT-BUILD-OPTIONS
directly).

The commit 9ab33150a0 ("perl: create and switch variables for hash
constants", 2020-06-22) converted each instance of the variable
$sha1_short into $oid_short in the Subversion code, since git-svn now
understands SHA-256. However, one conversion was missed.
As a result, Perl complains about the use of this variable:
Use of uninitialized value $sha1_short in regexp compilation at
/usr/lib64/perl5/vendor_perl/5.30.3/Git/SVN/Log.pm line 301, <$fh>
line 6.
Because we're parsing raw diff output here, the likelihood is very low
that we'll actually misparse the data, since the only lines we're going
to get starting with colons are the ones we're expecting. Even if we
had a newline in a path, we'd end up with a quoted path. Our regex is
just less strict than we'd like it to be.
However, it's obviously undesirable that our code is emitting Perl
warnings, so let's convert it to use the proper variable name.

There are several places throughout git-svn that use various hard-coded
constants. For matching object IDs, use the $oid variable. Compute the
record size we use for our revision storage based on the object ID.
When parsing the revision map format, use a wildcard in the pack format
since we know that the data we're parsing is always exactly the record
size. This lets us continue to use a constant for the pack format.
Finally, update several comments to reflect the fact that an object ID
may be of one of multiple sizes.

For users with "store-passwords = no" set in the "[auth]" section of
their ~/.subversion/config, SVN 1.9.0+ would fail with the
following message when attempting to call svn_auth_set_parameter:
Value is not a string (or undef) at Git/SVN/Ra.pm
Ironically, this breakage was caused by r1553823 in subversion:
"Make svn_auth_set_parameter() usable from Perl bindings."
Since 2007 (602015e0e6ec), git-svn has used a workaround to make
svn_auth_set_parameter usable internally. However this workaround
breaks under SVN 1.9+, which deals properly with the type mapping
and fails to recognize our workaround.

Since b19138b (git-svn: Make it incrementally faster by minimizing temp
files, v1.6.0), git-svn has been using the Git.pm temp_acquire and
temp_release mechanism to avoid unnecessary temp file churn and provide
a speed boost.
However, that change introduced a call to temp_acquire inside the
Git::SVN::Fetcher::close_file function for an 'svn_hash' temp file.
Because an SVN::Pool is active at the time this function is called, if
the Git::temp_acquire function ends up actually creating a new
FileHandle for the temp file (which it will the first time it's called
with the name 'svn_hash') that FileHandle will end up in the SVN::Pool
and should that pool have SVN::Pool::clear called on it that FileHandle
will be closed out from under Git::temp_acquire.
Since the only call site to Git::temp_acquire with the name 'svn_hash'
is inside the close_file function, if an 'svn_hash' temp file is ever
created its FileHandle is guaranteed to be created in the active
SVN::Pool.
This has not been a problem in the past because the SVN::Pool was not
being cleared. However, since dfa72fdb (git-svn: reload RA every
log-window-size, v2.2.0) the pool has been getting cleared periodically
at which point the FileHandle for the 'svn_hash' temp file gets closed.
Any subsequent calls to Git::temp_acquire for 'svn_hash', however,
succeed without creating/opening a new temporary file since it still has
the now invalid FileHandle in its cache. Callers that then attempt to
use that FileHandle fail with an error.
We avoid this problem by making sure the 'svn_hash' temp file is created
in the same place the 'svn_delta_...' and 'git_blob_...' temp files are
(and then temp_release'd) so that it can be safely used inside the
close_file function without having its FileHandle end up in an SVN::Pool
that gets cleared.
Additionally the Git.pm cat_blob function creates a bidirectional pipe
FileHandle using the IPC::Open2::open2 function. If that handle is
created too late, it also gets caught up in the SVN::Pool and incorrectly
closed by the SVN::Pool::clear call. But this only seems to happen with
more recent versions of Perl and svn.
To avoid this problem we add an explicit call to _open_cat_blob_if_needed
before the first call to SVN::Pool->new_default to make sure the open2
handle does not end up in the SVN::Pool.

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:

By default, Git used to set $LESS to -FRSX if $LESS was not set by
the user. The FRX flags actually make sense for Git (F and X because
sometimes the output Git pipes to less is short, and R because Git
pipes colored output). The S flag (chop long lines), on the other
hand, is not related to Git and is a matter of user preference. Git
should not decide for the user to change LESS's default.
More specifically, the S flag harms users who review untrusted code
within a pager, since a patch looking like:
-old code;
+new good code; [... lots of tabs ...] malicious code;
would appear identical to:
-old code;
+new good code;
Users who prefer the old behavior can still set the $LESS environment
variable to -FRSX explicitly, or set core.pager to 'less -S'.
The documentation in config.txt is made a bit longer to keep both an
example setting the 'S' flag (needed to recover the old behavior)
and an example showing how to unset a flag set by Git.

Just like we give a reasonable default for "less" via the LESS
environment variable, specify a reasonable default for "lv" via the
"LV" environment variable when spawning the pager.
* jn/pager-lv-default-env:
pager: set LV=-c alongside LESS=FRSX
On systems with lv configured as the preferred pager (i.e.,
DEFAULT_PAGER=lv at build time, or PAGER=lv exported in the
environment) git commands that use color show control codes instead of
color in the pager:
$ git diff
^[[1mdiff --git a/.mailfilter b/.mailfilter^[[m
^[[1mindex aa4f0b2..17e113e 100644^[[m
^[[1m--- a/.mailfilter^[[m
^[[1m+++ b/.mailfilter^[[m
^[[36m@@ -1,11 +1,58 @@^[[m
"less" avoids this problem because git uses the LESS environment
variable to pass the -R option ('output ANSI color escapes in raw
form') by default. Use the LV environment variable to pass 'lv' the
-c option ('allow ANSI escape sequences for text decoration / color')
to fix it for lv, too.
Noticed when the default value for color.ui flipped to 'auto' in
v1.8.4-rc0~36^2~1 (2013-06-10).

Subversion serf backend in versions 1.8.5 and below has a bug(*) that the
function creating the descriptor of a file change -- add_file() --
doesn't make a copy of its third argument when storing it on the
returned descriptor. As a result, by the time this field is used (in
transactions of file copying or renaming) it may well be released, and
the memory reused.
One of its possible manifestations is the svn assertion triggering on an
invalid path, with a message
svn_fspath__skip_ancestor: Assertion
`svn_fspath__is_canonical(child_fspath)' failed.
This patch works around this bug, by storing the value to be passed as

Subversion 1.7 and newer implement HTTPv2, an extension that should make HTTP
more efficient. Servers with support for this protocol will make the subversion
client library take an alternative code path that checks (with assertions)
whether the URL is "canonical" or not.
This patch fixes an issue I encountered while trying to `git svn dcommit` a
rename action for a file containing a single quote character ("User's Manual"
to "UserMan.tex"). It does not happen for older subversion 1.6 servers nor
non-HTTP(S) protocols such as the native svn protocol, only on an Apache server
shipping SVN 1.7. Trying to `git svn dcommit` under the aforementioned
conditions yields the following error which aborts the commit process:
Committing to http://example.com/svn ...
perl: subversion/libsvn_subr/dirent_uri.c:1520: uri_skip_ancestor:
Assertion `svn_uri_is_canonical(child_uri, ((void *)0))' failed.
error: git-svn died of signal 6
An analysis of the subversion source for the cause:
- The assertion originates from uri_skip_ancestor which calls
svn_uri_is_canonical, which fails when the URL contains percent-encoded values
that do not necessarily have to be encoded (not "canonical" enough). This is
done by a table lookup in libsvn_subr/path.c. Putting some debugging prints
revealed that the character ' is indeed encoded to %27 which is not
considered canonical.
- url_skip_ancestor is called by svn_ra_neon__get_baseline_info with the root
repository URL and path as parameters;
- which is called by copy_resource (libsvn_ra_neon/commit.c) for a copy action
(or in my case, renaming which is actually copy + delete old);
- which is called by commit_add_dir;
- which is assigned as a structure method "add_file" in
svn_ra_neon__get_commit_editor.
In the whole path, the path argument is not modified.
Through some more uninteresting wrapper functions, the Perl bindings gives you
access to the add_file method which will pass the path argument without
modifications to svn.
git-svn calls the "R"(ename) subroutine in Git::SVN::Editor which contains:
326 my $fbat = $self->add_file($self->repo_path($m->{file_b}), $pbat,
327 $self->url_path($m->{file_a}), $self->{r});
"repo_path" basically returns the path as-is, unless the "svn.pathnameencoding"
configuration property is set. "url_path" tries to escape some special
characters, but does not take all special characters into account, thereby
causing the path to contain some escaped characters which do not have to be
escaped.
The list of characters not to be escaped are taken from the
subversion/libsvn_subr/path.c file to fully account for all characters. Tested
with a filename containing all characters in the range 0x20 to 0x78 (inclusive).

Subversion's canonical URLs are intended to make URL comparison easy
and therefore have strict rules about what characters are special
enough to urlencode and what characters should be left alone.
When in the fallback codepath because unable to use libsvn's own
canonicalization function for some reason, escape special characters
in URIs according to the svn_uri__char_validity[] table in

Commit 56a853b62c0ae7ebaad0a7a0a704f5ef561eb795 also tried to solve
this issue, but was incomplete as described above.
Instead of using hand-rolled prompt-response code that only works with the
interactive terminal, a reusable prompt() method is introduced in this commit.

Subversion represents symlinks as ordinary files with content starting
with "link " and the svn:special property set to "*". Thus a file can
switch between being a symlink and a non-symlink simply by toggling
its svn:special property, and new checkouts will automatically write a
file of the appropriate type. Likewise, in subversion 1.6 and older,
running "svn update" would notice changes in filetype and update the
working copy appropriately.
Starting in subversion 1.7 (issue 4091), changes to the svn:special
property trip an assertion instead:
$ svn up svn-tree
Updating 'svn-tree':
svn: E235000: In file 'subversion/libsvn_wc/update_editor.c' \
line 1583: assertion failed (action == svn_wc_conflict_action_edit \
|| action == svn_wc_conflict_action_delete || action == \
svn_wc_conflict_action_replace)
Revisions prepared with ordinary svn commands ("svn add" and not "svn
propset") don't trip this because they represent these filetype
changes using a replace operation, which is approximately equivalent
to removal followed by adding a new file and works fine. Follow suit.
Noticed using t9100. After this change, git-svn's file-to-symlink
changes are sent in a format that modern "svn update" can handle and
tests t9100.11-13 pass again.

Subversion's svn_dirent_canonicalize() and svn_path_canonicalize()
APIs keep a leading slash in the return value if one was present on
the argument, which can be useful since it allows relative and
absolute paths to be distinguished.
When git-svn's canonicalize_path() learned to use these functions if
available, its semantics changed in the corresponding way. Some new
callers rely on the leading slash --- for example, if the slash is
stripped out then _canonicalize_url_ourselves() will transform
"proto://host/path/to/resource" to "proto://hostpath/to/resource".
Unfortunately the fallback _canonicalize_path_ourselves(), used when
the appropriate SVN APIs are not usable, still follows the old
semantics, so if that code path is exercised then it breaks. Fix it
to follow the new convention.
Noticed by forcing the fallback on and running tests. Without this
patch, t9101.4 fails:
Bad URL passed to RA layer: Unable to open an ra_local session to \
URL: Local URL 'file://homejrnsrcgit-scratch/t/trash%20directory.\
t9101-git-svn-props/svnrepo' contains unsupported hostname at \
/home/jrn/src/git-scratch/perl/blib/lib/Git/SVN.pm line 148
With it, the git-svn tests pass again.

The accessors should improve maintainability and enforce
consistent access to Git::SVN objects.

When using the {word,[...]} style of configuration for tags and branches,
it appears the intent is to only match whole path parts, since the words
in the {} pattern are meta-character quoted.
When the pattern word appears in the beginning or middle of the url,
it's matched completely, since the left side, pattern, and (non-empty)
right side are joined together with path separators.
However, when the pattern word appears at the end of the URL, the
right side is an empty pattern, and the resulting regex matches
more than just the specified pattern.
For example, if you specify something along the lines of
branches = branches/project/{release_1,release_2}
and your repository also contains "branches/project/release_1_2", you
will also get the release_1_2 branch. By restricting the match regex
with anchors, this is avoided.

Go through all the spots that use the new add_path_to_url() to
make a new URL and canonicalize them.
* copyfrom_path has to be canonicalized else find_parent_branch
will get confused
* due to the `canonicalize_url($full_url) ne $full_url)` line of
logic in gs_do_switch(), $full_url is left alone until after.
At this point SVN 1.7 passes except for 3 tests in
t9100-git-svn-basic.sh that look like an SVN bug to do with
symlinks.

Remove the ad-hoc versions.
This is mostly to normalize the process and ensure the URLs produced
don't have double slashes or anything.
Also provides a place to fix the corner case where a file path
contains a percent sign.

The old hand-rolled URL escape functions were inferior to
canonicalization functions.
Continuing to move towards getting everything canonicalizing the same way.
* Git::SVN->init_remote_config and Git::SVN::Ra->minimize_url both
have to canonicalize the same way else init_remote_config
will incorrectly think they're different URLs causing
t9107-git-svn-migrate.sh to fail.

Previously, our URL canonicalization didn't do much of anything.
Now it actually escapes and collapses slashes. This is mostly a cut & paste
of escape_url from git-svn.
This is closer to how SVN 1.7's canonicalization behaves. Doing it with
1.6 lets us chase down some problems caused by more effective canonicalization
without having to deal with all the other 1.7 issues on top of that.
* Remote URLs have to be canonicalized otherwise Git::SVN->find_existing_remote
will think they're different.
* The SVN remote is now written to the git config canonicalized. That
should be ok. Adjust a test to account for that.

This canonicalizes paths and urls as early as possible so we don't
have to remember to do it at the point of use. It will fix a swath
of SVN 1.7 problems in one go.
Its ok to double canonicalize things.
SVN 1.7 still fails, still not worrying about that.
