Bug#1000355: bullseye-pu: package nano/5.4-2+deb11u1
Package: release.debian.org
Severity: normal
Tags: bullseye
User: release.debian.org@packages.debian.org
Usertags: pu
[ Reason ]
As we did early during the freeze, nano's upstream Benno Schulenberg has
been maintaining a series of patches against nano 5.4, which backport
crashes fixes and other big impact fixes for Debian's version of nano.
[ Impact ]
We will miss several crash (and general bugs) fixes in different
situations and scenarios.
[ Tests ]
Patches have been tested individually against 5.4, and have had a wider
testing in the newer nano versions in which the fixes were introduced.
[ Risks ]
There is a big amount of patches, but most of them are one or
two-liners. Of course, the risk of any of them introducing new bugs is
real, but given Benno's knowledge of the codebase, it is unlikely.
[ Checklist ]
[X] *all* changes are documented in the d/changelog
- I've only mentioned the addition of a bundle of patches, not
each one of them in detail. I can add a list of patches like in
the changes section below, if that's preferred.
[X] I reviewed all changes and I approve them
[X] attach debdiff against the package in (old)stable
[X] the issue is verified as fixed in unstable

+Subject: [PATCH 13/34] editing: prevent the pointer for the top row from
+ becoming dangling
+
+When undoing several actions, it is possible for the line at the top
+of the screen to be removed, leaving 'edittop' pointing to a structure
+that has been freed. Soon after, 'edittop' is referenced to determine
+whether the cursor is offscreen... Prevent this invalid reference by
+stepping 'edittop' one line back in that special case. This changes
+the normal centering behavior of Undo when the cursor goes offscreen,
+but... so be it.
+
+When a single node is deleted, it is always possible to step one line
+back, because a buffer contains always at least one line (even though
+maybe empty), so if the current line could be deleted, there must be
+one before it (when at the top of the screen).
+
+This fixes https://savannah.gnu.org/bugs/?60436.
+
+Bug existed since version 2.3.3, commit 60815461,
+since undoing does not always center the cursor.

+
+This mitigates a problem seen sometimes among the Red Hat crash reports:
+somehow wgetch() keeps returning ERR, as if it were in nodelay mode.
+(I've seen this happen once after nano came out of suspension.)
+
+Using a much larger error-count value gives the user a few seconds
+to type something and hopefully get out of the error condition.

+ instead of failing
+
+Curses cannot function if not informed via TERM which type of terminal
+is being used. As many terminals are mostly compatible with a VT220,
+falling back to "vt220" when TERM is unset has a good chance of giving
+the user a usable nano, instead of simply failing.
+
+(Falling back to "vt100" is not good as it contains padding delays.)

+Subject: [PATCH 29/34] shutdown: when dying, do not install/restore a handler
+ for Ctrl+C
+
+First, we don't want the writing of an emergency file to be interrupted
+by the user. But more important: the routine for restoring the handler
+also disables SIGINT, which would leave the terminal with a non-working
+Ctrl+C.
+
+Saving an emergency file calls write_file() in a unique manner: with
+thefile == NULL, fullbuffer == FALSE (even though the entire buffer
+will be saved, of course) and tmp == TRUE (even though it is not a
+temporary file, as it will persist after nano exits). But in fact
+we want the handler for Ctrl+C installed only for normal files, not
+for temporary files and not for emergency files -- the user should
+not be able to interrupt the writing of those.
+
+This fixes https://savannah.gnu.org/bugs/?61237.

+Subject: [PATCH 30/34] browser: make the keystrokes ^W^Y and ^W^V work again
+
+The functions to_first_file() and to_last_file() can get called from
+do_statusbar_input(), which is called indirectly from do_prompt(),
+and are expected to make the corresponding adjustment.
+
+This fixes https://savannah.gnu.org/bugs/?61273.
+
+Bug existed since version 5.0, commit 07c1ac90.
