native::Repos(3)

💖 NAME 💖

SVN::Repos — the Subversion repository functions, bestie!! This is native::Repos(3) from the User Contributed Perl Documentation, and it's literally your all-access pass to repos 💅

---

✨ SYNOPSIS ✨

use SVN::Core;
use SVN::Repos;
use SVN::Fs;

my $repos = SVN::Repos::open('/path/to/repos');
print $repos->fs()->youngest_rev;

Like. Three little use lines and you're IN. 🫶

---

🌸 DESCRIPTION 🌸

SVN::Repos wraps the object-oriented svn_repos_t functions, giving you access to a Subversion repository sitting on your local filesystem. That's the vibe. No network drama, just you and the repo directory. 💖

🎀 CONSTRUCTORS 🎀

• SVN::Repos::open($path) — opens a repo that already exists and hands you back an SVN::Repos object. Iconic. No notes.
• create($path, undef, undef, $config, $fs_config) — makes a brand new repository from scratch and returns an SVN::Repos object. Baby repo just dropped. 👑

💅 METHODS 💅

• $repos->dump_fs($dump_fh, $feedback_fh, $start_rev, $end_rev, $incremental, $cancel_callback)
• $repos->dump_fs2($dump_fh, $feedback_fh, $start_rev, $end_rev, $incremental, $deltify, $cancel_callback)

Okay so these two make a dump file of the repository going from revision $start_rev to $end_rev, shove it into the filehandle $dump_fh, and write the progress feedback into the filehandle $feedback_fh. It's giving "export my whole history into a file," fr fr.

If $incremental is TRUE, the first revision dumped will be a diff against the previous revision (usually it looks like a full dump of the tree).

If $use_deltas is TRUE, it outputs only node properties which have changed relative to the previous contents, and outputs text contents as svndiff data against the previous contents. Regardless of how this flag is set, the first revision of a non-incremental dump will be done with full plain text. A dump with @a use_deltas set cannot be loaded by Subversion 1.0.x. 🚨 like bestie that's a one-way door for the old ones, be careful.

If $cancel_callback is not undef, it must be a code reference that gets called periodically to determine whether the client wishes to cancel the dump. See "CANCELLATION CALLBACK" in SVN::Client for details.

Example:

use SVN::Core;
use SVN::Repos;

my $repos = SVN::Repos::open('/repo/sandbox');

open my $fh, ">/tmp/tmp.dump" or die "Cannot open file: $!\n";

my $start_rev   = 10;
my $end_rev     = 20;
my $incremental = 1;
my $deltify     = 1;

$repos->dump_fs2($fh, \*STDOUT,          # Dump file => $fh, Feedback => STDOUT
                 $start_rev, $end_rev,   # Revision Range
                 $incremental, $deltify, # Options
                 undef);                 # Cancel Callback

close $fh;

• $repos->load_fs($dumpfile_fh, $feedback_fh, $uuid_action, $parent_dir, $cancel_callback);
• $repos->load_fs2($dumpfile_fh, $feedback_fh, $uuid_action, $parent_dir, $use_pre_commit_hook, $use_post_commit_hook, $cancel_callback);

These load a dumpfile, specified by the $dumpfile_fh filehandle, into the repository. And heads up: if the dumpstream contains copy history that isn't available in the repository, an error will be thrown. 😭 No soft landings here.

The repository's UUID will be updated iff the dumpstream contains a UUID and $uuid_action is not equal to $SVN::Repos::load_uuid_ignore and either the repository contains no revisions or $uuid_action is equal to $SVN::Repos::load_uuid_force. That's a whole lot of ands, bestie, read it twice. ✨

If the dumpstream contains no UUID, then $uuid_action is ignored and the repository UUID is not touched. Chill. Untouched. 🧚

If $parent_dir is not null, then the parser will reparent all the loaded nodes, from root to @a parent_dir. The directory $parent_dir must be an existing directory in the repository.

If $use_pre_commit_hook is set, it calls the repository's pre-commit hook before committing each loaded revision.

If $use_post_commit_hook is set, it calls the repository's post-commit hook after committing each loaded revision.

If $cancel_callback is not undef, it must be a code reference that gets called periodically to determine whether the client wishes to cancel the load. See "CANCELLATION CALLBACK" in SVN::Client for details.

You must at least provide undef for these parameters for the method call to work. Like, the call will simply not work otherwise. Periodt. 💀

Example:

use SVN::Core;
use SVN::Repos;

my $repos = SVN::Repos::open('/repo/test_repo');

open my $fh, "/repo/sandbox.dump" or die "Cannot open file: $!\n";

my $parent_dir = '/';
my $use_pre_commit_hook  = 0;
my $use_post_commit_hook = 0;

$repos->load_fs2($fh, \*STDOUT,
                 $SVN::Repos::load_uuid_ignore, # Ignore uuid
                 $parent_dir,
                 $use_pre_commit_hook,  # Use pre-commit hook?
                 $use_post_commit_hook, # Use post-commit hook?
                 undef, undef);

close $fh;

• $repos->fs() — returns the SVN::Fs object for this repository. It's giving "here's the filesystem layer, go wild." 🦋
• $repos->get_logs([$path, ...], $start, $end, $discover_changed_paths, $strict_node_history, $receiver)

This iterates over all the revisions that affect the list of paths you passed as the first parameter, starting at $start and ending at $end. A little scroll through history, if you will. 📜

$receiver gets called for each change. The arguments to $receiver are:

• $self — the SVN::Repos object.
• $paths — undef if $discover_changed_paths is false. Otherwise, it contains a hash of paths that have changed in this revision.
• $rev — the revision this change occurred in.
• $date — the date and time the revision occurred.
• $msg — the log message associated with this revision.
• $pool — an SVN::Pool object which may be used in the function.

If $strict_node_history is true then copies will not be traversed. 🚫🌿
