Add compat, compat_local, compat_remote configuration options.
Used for busybox: instead of running `readlink -e` (which is not
available on busybox), run `readlink -f` followed by `test -d`.
btrbk requires "btrfs subvolume list|show" queries from the mount
point in order to build btrfs trees. This conflicts with tightly set
--restrict-path.
Package maintainers like to build everything from scratch, removing
overhead. Again, we apologize for the inconvenience.
Note that reproducible builds are still guaranteed by setting
SOURCE_DATE_EPOCH in doc/Makefile.
Reverts: a6dbd60e5a documentation: add pre-generated man pages: from groff to asciidoc and back again
This reduces build-time dependencies to zero, helping package
maintainers and providing reproducible builds.
NOTE: generated man pages will only be updated on releases. In order
to make sure the docs are correctly rebuilt, run "make clean man". We
apologize for the inconvenience.
From Groff to Asciidoc and Back Again [1]
=========================================
| Comparison | Links |
| -------------------------------------------------------------------------| -------------------------------------------------------------------------------------------------------------- |
| **Plain ROFF** | |
| +++ Best result for `man` (our main goal!) | |
| - Not supported by github | [btrbk(1) v0.25.1 in plain groff](https://github.com/digint/btrbk/blob/v0.25.1/doc/btrbk.1) |
| - No decent converters: e.g. `groff -Txhtml -mandoc` | [btrbk(1) v0.25.1 at digint.ch (official site)](https://digint.ch/btrbk/doc/archive/btrbk-0.25.1/btrbk.1.html) |
| | |
| **asciidoc** | |
| + Decent (scriptable!) html | [btrbk(1) v0.26.1 at digint.ch (official site)](https://digint.ch/btrbk/doc/archive/btrbk-0.26.1/btrbk.1.html) |
| + Supported by github (helps contributors writing decent documentation) | [btrbk.1.asciidoc v0.26.1 at github](https://github.com/digint/btrbk/blob/master/doc/btrbk.1.asciidoc) |
| | |
| **asciidoc (`xmlto`, `atx`)** | http://asciidoc.org/ |
| + Good result for `man` | |
| - EOL (why care that much? it works fine!) | [asciidoc EOL notice at github](https://github.com/asciidoc/asciidoc/releases/tag/8.6.10) |
| | |
| **asciidoc (`asciidoctor`)** | https://asciidoctor.org |
| - Pulls in tons of ruby (build depends) | https://bugs.gentoo.org/681056 |
| -- Implies to commit a pre-converted `doc/btrbk.1` | |
| + Seems more evolved than `xmlto`, still actively maintained | |
| | |
| **rst (`xrst2man.py` from docutils)** | |
| - Worse result for `man` | |
| ++ Good html converters (after having a quick look at it) | |
| - Not so well supported by github | [btrbk.1.rst v0.26.1 at github](https://github.com/digint/btrbk/blob/rst2man/doc/btrbk.1.rst) |
[1] https://github.com/digint/btrbk/pull/219 (edited)
Remove support for man page generation using asciidoc "a2x": The
project is discontinued, and depends on Python 2.7.
As we will provide pre-generated man pages as of btrbk-0.28.0, this is
not needed any more.
Makes sure that if, for whatever reason, a subvolume having correct
btrbk name scheme does NOT share any extents with previous snapshots
is never used as parent.
Note that if a related parent is found, the unrelated closest
older/newer (by btrbk timestamp) subvolumes are still added as clone
sources.
Allowed values for "incremental_resolve":
- "mountpoint" (default): Use parents in the filesystem tree below
mount points of source `<volume-directory>/<snapshot-dir>` and
target `<target-directory>`.
- "directory": Use parents strictly below source/target
directories. Useful when restricting access, e.g. when using
ssh_filter_btrbk.sh.
- "_all_accessible" (experimental): Use parents from all mount points.
Note that using "_all_accessible" causes btrfs-progs to fail:
- btrfs send -p: "ERROR: not on mount point: /path/to/mountpoint"
- btrfs receive: "ERROR: parent subvol is not reachable from inside the root subvol"
