* [PATCH v3 08/16] pathspec: always show mnemonic and name in unsupported_magic
From: Brandon Williams @ 2016-12-13 23:14 UTC (permalink / raw)
To: git; +Cc: Brandon Williams, sbeller, pclouds, gitster
In-Reply-To: <1481670870-66754-1-git-send-email-bmwill@google.com>
For better clarity, always show the mnemonic and name of the unsupported
magic being used. This lets users have a more clear understanding of
what magic feature isn't supported. And if they supplied a mnemonic,
the user will be told what its corresponding name is which will allow
them to more easily search the man pages for that magic type.
This also avoids passing an extra parameter around the pathspec
initialization code.

* [PATCH v3 06/16] pathspec: copy and free owned memory
From: Brandon Williams @ 2016-12-13 23:14 UTC (permalink / raw)
To: git; +Cc: Brandon Williams, sbeller, pclouds, gitster
In-Reply-To: <1481670870-66754-1-git-send-email-bmwill@google.com>
The 'original' string entry in a pathspec_item is only duplicated some
of the time, instead always make a copy of the original and take
ownership of the memory.
Since both 'match' and 'original' string entries in a pathspec_item are
owned by the pathspec struct, they need to be freed when clearing the
pathspec struct (in 'clear_pathspec()') and duplicated when copying the
pathspec struct (in 'copy_pathspec()').
Also change the type of 'match' and 'original' to 'char *' in order to
more explicitly show the ownership of the memory.

* [PATCH v3 01/16] mv: remove use of deprecated 'get_pathspec()'
From: Brandon Williams @ 2016-12-13 23:14 UTC (permalink / raw)
To: git; +Cc: Brandon Williams, sbeller, pclouds, gitster
In-Reply-To: <1481670870-66754-1-git-send-email-bmwill@google.com>
Convert the 'internal_copy_pathspec()' function to 'prefix_path()'
instead of using the deprecated 'get_pathspec()' interface. Also,
rename 'internal_copy_pathspec()' to 'internal_prefix_pathspec()' to be
more descriptive of what the funciton is actually doing.
In addition to this, fix a memory leak caused by only duplicating some
of the pathspec elements. Instead always duplicate all of the the
pathspec elements as an intermediate step (with modificationed based on
the passed in flags). This way the intermediate strings can then be
freed after getting the result from 'prefix_path()'.

* [PATCH v3 09/16] pathspec: simpler logic to prefix original pathspec elements
From: Brandon Williams @ 2016-12-13 23:14 UTC (permalink / raw)
To: git; +Cc: Brandon Williams, sbeller, pclouds, gitster
In-Reply-To: <1481670870-66754-1-git-send-email-bmwill@google.com>
The logic used to prefix an original pathspec element with 'prefix'
magic is more general purpose and can be used for more than just short
magic. Remove the extra code paths and rename 'prefix_short_magic' to
'prefix_magic' to better indicate that it can be used in more general
situations.
Also, slightly change the logic which decides when to prefix the
original element in order to prevent a pathspec of "." from getting
converted to "" (empty string).

* [PATCH v3 05/16] pathspec: remove the deprecated get_pathspec function
From: Brandon Williams @ 2016-12-13 23:14 UTC (permalink / raw)
To: git; +Cc: Brandon Williams, sbeller, pclouds, gitster
In-Reply-To: <1481670870-66754-1-git-send-email-bmwill@google.com>
Now that all callers of the old 'get_pathspec' interface have been
migrated to use the new pathspec struct interface it can be removed
from the codebase.
Since there are no more users of the '_raw' field in the pathspec struct
it can also be removed. This patch also removes the old functionality
of modifying the const char **argv array that was passed into
parse_pathspec. Instead the constructed 'match' string (which is a
pathspec element with the prefix prepended) is only stored in its
corresponding pathspec_item entry.

* [PATCH v3 13/16] pathspec: create parse_element_magic helper
From: Brandon Williams @ 2016-12-13 23:14 UTC (permalink / raw)
To: git; +Cc: Brandon Williams, sbeller, pclouds, gitster
In-Reply-To: <1481670870-66754-1-git-send-email-bmwill@google.com>
Factor out the logic responsible for the magic in a pathspec element
into its own function.
Also avoid calling into the parsing functions when
`PATHSPEC_LITERAL_PATH` is specified since it causes magic to be
ignored and all paths to be treated as literals.

* [PATCH v2 6/6] unicode_width.h: update the width tables to Unicode 9.0
From: Beat Bolli @ 2016-12-13 23:31 UTC (permalink / raw)
To: git; +Cc: Beat Bolli
In-Reply-To: <1481671904-1143-1-git-send-email-dev+git@drbeat.li>
Rerunning update-unicode.sh that we fixed in the previous commits
produces these new tables.

* [PATCH v2 0/6] unicode_width.h: update the width tables to Unicode 9.0
From: Beat Bolli @ 2016-12-13 23:31 UTC (permalink / raw)
To: git
This is v2 of my Unicode 9.0 series. After a short discussion [1], we
decided to move the generator script into contrib. This is what this
series now does first. The script is then updated in contrib.
Diff to v1:
- complete commit reordering
- fix nits in the commit messages

* [PATCH v2 4/6] update-unicode.sh: automatically download newer definition files
From: Beat Bolli @ 2016-12-13 23:31 UTC (permalink / raw)
To: git; +Cc: Beat Bolli
In-Reply-To: <1481671904-1143-1-git-send-email-dev+git@drbeat.li>
Checking just for the unicode data files' existence is not sufficient;
we should also download them if a newer version exists on the Unicode
consortium's servers. Option -N of wget does this nicely for us.

* [PATCH v2 2/6] update_unicode.sh: remove an unnecessary subshell level
From: Beat Bolli @ 2016-12-13 23:31 UTC (permalink / raw)
To: git; +Cc: Beat Bolli
In-Reply-To: <1481671904-1143-1-git-send-email-dev+git@drbeat.li>
After the move into contrib/update-unicode, we no longer create the
unicode directory to have a clean working folder. Instead, the directory
of the script is used. This means that the subshell can be removed.

* [PATCH v2 5/6] update_unicode.sh: remove the plane filter
From: Beat Bolli @ 2016-12-13 23:31 UTC (permalink / raw)
To: git; +Cc: Beat Bolli
In-Reply-To: <1481671904-1143-1-git-send-email-dev+git@drbeat.li>
The uniset upstream has accepted my patches that eliminate the Unicode
plane offsets from the output in '--32' mode.
Remove the corresponding filter in update_unicode.sh.
This also fixes the issue that the plane offsets were not removed from
the second uniset call.

* [PATCH v2 3/6] update_unicode.sh: pin the uniset repo to a known good commit
From: Beat Bolli @ 2016-12-13 23:31 UTC (permalink / raw)
To: git; +Cc: Beat Bolli
In-Reply-To: <1481671904-1143-1-git-send-email-dev+git@drbeat.li>
The uniset upstream has added more commits that for example change the
hexadecimal output in '--32' mode to decimal. Let's pin the repo to a
commit that still outputs the width tables in the format we want.

* [PATCH v2 1/6] update_unicode.sh: move it into contrib/update-unicode

As it's used only by a tiny minority of the Git developer population,
this script does not belong into the main Git source directory.
Move it into contrib/ and adjust the paths to account for the new
location.

+TL;DR: Run update_unicode.sh after the publication of a new Unicode
+standard and commit the resulting unicode_widths.h file.
+
+The long version
+================
+
+The Git source code ships the file unicode_widths.h which contains
+tables of zero and double width Unicode code points, respectively.
+These tables are generated using update_unicode.sh in this directory.
+update_unicode.sh itself uses a third-party tool, uniset, to query two
+Unicode data files for the interesting code points.
+
+On first run, update_unicode.sh clones uniset from Github and builds it.
+This requires a current-ish version of autoconf (2.69 works per December
+2016).
+
+On each run, update_unicode.sh checks whether more recent Unicode data
+files are available from the Unicode consortium, and rebuilds the header
+unicode_widths.h with the new data. The new header can then be
+committed.

Support for git-p4 worktrees.
Adds test cases for using git from a worktree, and
specifying the git directory either with the --git-dir
command-line option, or with $ENV{GIT_DIR}.

* Re: Proposal for an increased `gitk` cohesion with `git stash`.
From: Uxío Prego @ 2016-12-14 0:36 UTC (permalink / raw)
To: git, Paul Mackerras
In-Reply-To: <20161212093613.GD20934@fergus.ozlabs.ibm.com>
Dearest all,
am sorry my previous message did not enter the list (cross my fingers this will). I won't be pasting it verbatim because shame on me it leaked zombie processes (but that part got silently dropped out by kind Paul).
In case anyone could be interested in the topic, and because a thorough reply will take me some time, my most recent edit of this is hosted at https://gist.githubusercontent.com/uprego/d8c3c059c56ebb911974bb905157a81e/raw/6a08d9e0ce9c2b1decd4ed92acc924961c7f7769/gitk%2520multi%2520stash%2520patch. All problems shown I still think is a nice start (of course p.o.c / pre alpha) if anyone ever wanted to get this working or even fix the current problems it has.
As Paul recommend I'll be reworking and giving a patch against a rev of his upstream.
I'm going to try his code tips to improve non obvious design choices, and (even he doesn’t commented it and seems to me most important) really put an extra effort in not changing the behaviour of `gitk` (i.e. started without '--all').
Then some testing against large repos, github.com/cartodb/cartodb then github.com/odoo/oodo finally Linux; will be done.
The performance issue Paul points to, I don't think is impacting me, but now I reckon (just as one example) there are people who develop using IDEs that leave garbaged unuseful stashes, and that has to be taken into account as scenario. And the large repos. But this file event handlers thing is something that will make me lag to fix it, even surprised me because the remaining of the subroutines that I patched are just doing the same I typed, I just replicated near source (general revs processing) because I have no idea Tcl, even do not give a shit, but have to say Tcl is fun C: and an interesting discovery though. I hope that was not a trick to get me into improving the performance of the near loop that process ALL involved revs (and the similar for refs)! I'm old and tired to get into performance hacking.
I guess you know, the underworked grep must be an easy solve, probably excluding ' refs/stash' because a branch named 'refs/stash' is allowed but not a branch named ' refs/stash' (IDK which version I was trying but I will try both 1.x.y and 2.x.y in time).
Finally... if you don't leverage stashing too much, what is the practice? committing ephemeral to later reset and recommit? I hope I don't just needed a lesson on git-reset instead of all this.
Please pardon my potentially mangler mail client. Yours sincerely, regards and thanks for your time,
