git-add--interactive.perl: Remove two unused variables

2012-06-25T17:06:09Z

The patch 8f0bef6 refactored this script and made the variable $fh unneeded in subs diff_applies and patch_update_file, but forgot to remove them. Signed-off-by: Thomas Badie Signed-off-by: Junio C Hamano

add--interactive: ignore unmerged entries in patch mode

2012-04-05T16:01:03Z

When "add -p" sees an unmerged entry, it shows the combined diff and then immediately skips the hunk. This can be confusing in a variety of ways, depending on whether there are other changes to stage (in which case you get the superfluous combined diff output in between other hunks) or not (in which case you get the combined diff and the program exits immediately, rather than seeing "No changes"). The current behavior was not planned, and is just what the implementation happens to do. Instead, let's explicitly remove unmerged entries from our list of modified files, and print a warning that we are ignoring them. We can cheaply find which entries are unmerged by adding "--raw" output to the "diff-files --numstat" we already run. There is one non-obvious thing we must change when parsing this combined output. Before this patch, when we saw a numstat line for a file that did not have index changes, we would create a new record with 'unchanged' in the 'INDEX' field. Because "--raw" comes before "--numstat", we must move this special-case down to the raw-line case (and it is sufficient to move it rather than handle it in both places, since any file which has a --numstat will also have a --raw entry).

add -i: ignore terminal escape sequences

2011-05-18T03:44:17Z

On the author's terminal, the up-arrow input sequence is ^[[A, and thus fat-fingering an up-arrow into 'git checkout -p' is quite dangerous: git-add--interactive.perl will ignore the ^[ and [ characters and happily treat A as "discard everything". As a band-aid fix, use Term::Cap to get all terminal capabilities. Then use the heuristic that any capability value that starts with ^[ (i.e., \e in perl) must be a key input sequence. Finally, given an input that starts with ^[, read more characters until we have read a full escape sequence, then return that to the caller. We use a timeout of 0.5 seconds on the subsequent reads to avoid getting stuck if the user actually input a lone ^[. Since none of the currently recognized keys start with ^[, the net result is that the sequence as a whole will be ignored and the help displayed.

"add -p": work-around an old laziness that does not coalesce hunks

2011-04-29T22:27:59Z

Since 0beee4c (git-add--interactive: remove hunk coalescing, 2008-07-02), "git add--interactive" behaves lazily and passes overlapping hunks to the underlying "git apply" without coalescing. This was partially corrected by 7a26e65 (its partial revert, 2009-05-16), but overlapping hunks are still passed when the patch is edited. Teach "git apply" the --allow-overlap option that disables a safety feature that avoids misapplication of patches by not applying patches to overlapping hunks, and pass this option form "add -p" codepath. Do not even advertise the option, as this is merely a workaround, and the correct fix is to make "add -p" correctly coalesce adjacent patch hunks. Signed-off-by: Junio C Hamano

add--interactive.perl: factor out repeated --recount option

2011-04-29T22:27:59Z

Depending on the direction and the target of patch application, we would need to pass --cached and --reverse to underlying "git apply". Also we only pass --check when we are not applying but just checking. But we always pass --recount since 8cbd431 (git-add--interactive: replace hunk recounting with apply --recount, 2008-07-02). Instead of repeating the same --recount over and over again, move it to a single place that actually runs the command, namely, "run_git_apply" subroutine. Signed-off-by: Junio C Hamano

add -p: 'q' should really quit

2011-04-29T22:25:03Z

The "quit" command was added in 9a7a1e0 (git add -p: new "quit" command at the prompt, 2009-04-10) to allow the user to say that hunks other than what have already been chosen are undesirable, and exit the interactive loop immediately. It forgot that there may be an undecided hunk before the current one. In such a case, the interactive loop still goes back to the beginning. Clear all the USE bit for undecided hunks and exit the loop. Signed-off-by: Junio C Hamano

* jl/add-p-reverse-message: Correct help blurb in checkout -p and friends

Correct help blurb in checkout -p and friends

2010-10-28T22:28:39Z

When git checkout -p from the index or HEAD is run in edit mode, the help message about removing '-' and '+' lines was backwards. Because it is reverse applying the patch, the meanings of '-' and '+' are reversed. Signed-off-by: Jonathan "Duke" Leto Acked-by: Thomas Rast Signed-off-by: Junio C Hamano

perl: use "use warnings" instead of -w

2010-09-27T19:37:56Z

Change the Perl scripts to turn on lexical warnings instead of setting the global $^W variable via the -w switch. The -w sets warnings for all code that interpreter runs, while "use warnings" is lexically scoped. The former is probably not what the authors wanted. As an auxiliary benefit it's now possible to build Git with: PERL_PATH='/usr/bin/env perl' Which would previously result in failures, since "#!/usr/bin/env perl -w" doesn't work as a shebang.

perl: bump the required Perl version to 5.8 from 5.6.[21]

2010-09-27T19:37:41Z

Formalize our dependency on perl 5.8, bumped from 5.6.[12]. We already used the three-arg form of open() which was introduced in 5.6.1, but t/t9700/test.pl explicitly depended on 5.6.2. However git-add--interactive.pl has been failing on the 5.6 line since it was introduced in v1.5.0-rc0~12^2~2 back in 2006 due to this open syntax: sub run_cmd_pipe { my $fh = undef; open($fh, '-|', @_) or die; return <$fh>; } Which when executed dies on "Can't use an undefined value as filehandle reference". Several of our tests also fail on 5.6 (even more when compiled with NO_PERL_MAKEMAKER=1): t2016-checkout-patch.sh t3904-stash-patch.sh t3701-add-interactive.sh t7105-reset-patch.sh t7501-commit.sh t9700-perl-git.sh Our code is bitrotting on 5.6 with no-one interested in fixing it, and pinning us to such an ancient release of Perl is keeping us from using useful features introduced in the 5.8 release. The 5.6 series is now over 10 years old, and the 5.6.2 maintenance release almost 7. 5.8 on the other hand is more than 8 years old. All the modern Unix-like operating systems have now upgraded to it or a later version, and 5.8 packages are available for old IRIX, AIX Solaris and Tru64 systems.
