[PATCH] git-svn: Support for git-svn propset
This change allows git-svn to support setting subversion properties.
Very useful for manually setting properties when committing to a
subversion repo that *requires* properties to be set without requiring
moving your changeset to separate subversion checkout in order to
set props.
This change is initially from David Fraser
Appearing here: http://marc.info/?l=git&m=125259772625008&w=2
They are now forward ported to most recent git along with fixes to
deal with files in subdirectories.

[PATCH] git-svn: Support for propset
Hello folks, I have resurrected the code submitted by David Fraser to facilitate git-svn to set properties on files. This is my very first patch submission to git(1) so please be gentle. I have tried my best to abide with all the instructions located here: https://github.com/git/git/blob/master/Documentation/SubmittingPatches I've cc'd the top 4 people who have been active in the area: ~/git/git % git log --since '2010-01-01' git-svn.perl |grep Author | sort | uniq -c | sort -n | tail -4 6 Author: Eric Wong 9 Author: Jonathan Nieder 13 Author: Junio C Hamano 19 Author: Michael G. Schwern And of course: git@vger.kernel.org We (FreeBSD) and my company that uses FreeBSD are starting to use git-svn to collaborate with each other, however our (FreeBSD's) central repo is subversion and requires us to set properties in order to commit. This change would be tremendously helpful for a number of us in order to cut overhead of the git<->subversion bridge. Effectively with this patch we can commit directly to FreeBSD and FreeBSD ports using git. The next email should have the patch in format that is consumable by "git am" when applied against the master branch. I have been testing this and have done a number of commits directly to FreeBSD kernel and FreeBSD ports (packages) system using this patch successfully.

as if it encountered an unknown/non-standard file type on a normal
operating system, which could die() if needed in the function that
called stat().
Should I send an updated patch that die()s there?
David
Not yet, please wait with a V2 patch until I finished my thinking ;-)
I take back the suggestion with the die(). I was thinking how to handle
unforeseen types, which may show up on the z/OS some day,
So die() is not a good idea, it is better to ignore them, what the code
does.
Knowing that Git does not track block devices, nor character devices nor
sockets,
the above code could be simplyfied even more, by mapping everything which
is not a directory, a file or a softlink to "device type 0)
This is just a suggestion, I want to here from others as well:
int perm_bits = native_mode & 0;
if (S_ISREG(native_mode))
return 010 | perm_bits;
if (S_ISDIR(native_mode))

I wonder if we could reuse "git config" which is already a "kitchen synk" command to get/set a lot of parameters. Maybe we could dedicate a "git" or "virtual" or "proc" or "sys" (like /proc or /sys in Linux) namespace for these special config parameters that would not necessarily reflect something in the config file. "git config git.man-path" would be the same as "git --man-path". "git config git.root" would be the same as "git rev-parse --show-toplevel". "git config git.exec-path mypath" would allow us to override the path to the subcommands, probably by saving something in the config file. If we wanted for example to try just once a special exec-path we could use: git -c git.exec-path=/path/to/git-foo foo Best, Christian. -- To unsubscribe from this list: send the line "unsubscribe git" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html

Re: [PATCH v5] Add another option for receive.denyCurrentBranch
Thanks, will queue. I think we would need a bit more tests to protect the feature from future changes, if you care about the cleanliness requirement of this feature which is a lot stricter than that of "git checkout". Perhaps like this one on top. -- >8 -- From: Junio C Hamano Date: Sun, 30 Nov 2014 17:54:30 -0800 Subject: [PATCH] t5516: more tests for receive.denyCurrentBranch=updateInstead The previous one tests only the case where a path to be updated by the push-to-deploy has an incompatible change in the target's working tree that has already been added to the index, but the feature itself wants to require the working tree to be a lot cleaner than what is tested. Add a handful more tests to protect the feature from future changes that mistakenly (from the viewpoint of the inventor of the feature) loosens the cleanliness requirement, namely: - A change only to the working tree but not to the index is still a change to be protected; - An untracked file in the working tree that would be overwritten by a push-to-deploy needs to be protected; - A change that happens to make a file identical to what is being pushed is still a change to be protected (i.e. the feature's cleanliness requirement is more strict than that of checkout). Also, test that a stat-only change to the working tree is not a reason to reject a push-to-deploy.

I cannot offhand comment on the last question above, but the
reliance on exact S_IFxxx bit assignment was identified as a
potential problem from very early days of Git that we have known
about but didn't have need to address on any system that mattered.
This is a long overdue issue and I am happy to see it getting
tackled. The patch seems to be a sensible implementation of your
design decision to use the one-way conversion.

For the record, "rev-parse" is not about revisions in the first place. It started purely as a helper to implement "git log" in terms of "git rev-list" piped to "git diff-tree --stdin", which requires you to sift a command line argument list given to such a scripted "git log" into those to be passed to "rev-list" (i.e. primarily revision ranges) and those to be passed to "diff-tree" (i.e. primarily diff options and pathspecs). Various subcommands "rev-parse" takes such as --show-git-dir were added only because there wasn't any single best "kitchen sink" command to tuck such a small feature that do not deserve a standalone command (e.g. "git root", which makes it sound as if the top-level of the working tree is the most important thing in the world, and adding other useful things such as --show-prefix to it, while it would make sense to have them there from the implementation point of view, would be hard to justify against the connotation the word "root" gives us), and we happened to pick "rev-parse" as a "kitchen sink" place, which is not better or worse as anything else. If I were redoing this today, I would probably nominate the "git" potty as such a "kitchen synk" command. We have "--man-path" that shows the location of the manual pages, "--exec-path[=path]" that either shows or allows us to override the path to the subcommands, and "--show-prefix", "--show-toplevel", and friends may feel quite at home there. -- To unsubscribe from this list: send the line "unsubscribe git" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html

As a reviewer / contributor (not speaking as the top maintainer), I would say that everything in one place, and for that one place mailbox is preferrable. "Somebody commented on (this instance of | the central) Gerrit, come look at it" is not usable; sending that comment out to those who work in their MUA, and allowing them to respond via their MUA probably adding their response as a new comment to Gerrit) would be usable. When I had to view a large-ish series by Ronnie on Gerrit, it was fairly painful. The interaction on an individual patch might be more convenient and efficient using a system like Gerrit than via e-mailed patch with reply messages, but as a vehicle to review a large series and see how the whole thing fits together, I did not find pages that made it usable (I am avoiding to say "I found it unusable", as that impression may be purely from that I couldn't find a more suitable pages that showed the same information in more usable form, i.e. user inexperience). Speaking of the "whole picture", I am hesitant to see us pushed into the "here is a central system (or here are federated systems) to handle only the patch reviews" direction; our changes result after discussing unrelated features, wishes, or bugs that happen outside of any specific patches with enough frequency, and that is why I prefer "everything in one place" aspect of the development based on the mailing list. That is not to say that the "one place" has forever to be the mailing list, though. But the tooling around an e-mail based workflow (e.g. marking threads as "worth revisiting" for later inspection, saving chosen messages into a mailbox and running "git am" on it) is already something I am used to. Whatever system we might end up migrating to, the convenience it offers has to beat the convenience of existing workflow to be worth switching to, at least to me as a reviewer/contributor. As the maintainer, I am not worried too much. As long as the mechanism can (1) reach "here is a series that is accepted by reviewers whose opinions are trusted" efficiently, and (2) allow me to queue the result without mistakes, I can go along with anything reasonable. -- To unsubscribe from this list: send the line "unsubscribe git" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html

One thing to be careful about is that the approach HEAD, HEAD~, etc. does allow this to be extended to cover merge cases as the old thread speculated, it will make it impossible to pass any kind of information, other than "here are the parents of the results", to the hook. Of course, there are ways to make sure that we won't paint us into an unescapable corner, e.g. an obvious example (not necessarily the best) being to pass "HEAD", "HEAD~", "b76b088 b260d26" etc., in other words, passing these parents still as a single argument, multiple parents concatenated with some delimiters, so that "$1" will always be "who are the parent(s)" even when we needed to later pass other sorts of information. -- To unsubscribe from this list: send the line "unsubscribe git" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html

[PATCH/RFC v2] Squashed changes for multiple worktrees vs. submodules
builtin/checkout.c: use absolute path instead of given argument for
picking worktree name, it happens to be needed because for submodule
checkout the new worktree is always "."
environment.c: add GIT_COMMON_DIR to local_repo_env
git-submodule.sh: implement automatic cloning of main repository
and checkout to new worktree at "submodule update --init"
path.c, setup.c, submodule.c: fix "diff --submodule" when
submodule is a linked worktree

Signed-off-by: Max Kirillov

Hi.
Thanks for including my 2 patches.
But, while hacking the submodule init I became more convinced that the
modules directory should be common and submodules in checkout should be
a checkouts of the submodule. Because this is looks like concept of
submodules, that they are unique for the lifetime of repository, even if
they do not exist in all revisions. And if anybody want to use fully
independent checkout they can be always checked out manually. Actually,
after a submodule is initialized and have a proper gitlink, it can be
updated and inquired regardless of where it points to.
So that one I think is not needed. I have instead some changes to
git-submodule, but have not prepared them yet as an exportable history.
I am submitting here squashed changes which I have so far, to give an
idea where it goes. I'll try to prepare a proper patch series as soon as
I can.
They contain change $gmane/258173, which I think is important,
especially because it is required not only for initialization but for
regular work also, and changes for initialization of submodules.
They are rebased on top of you patches excluding the 34/34 patch.

[PATCH v2] t0027: check the eol conversion warnings
Depending on the file content, eol parameters and .gitattributes
"git add" may give a warning when the eol of a file will change
when the file is checked out again.
There are 2 different warnings, either "CRLF will be replaced..." or
"LF will be replaced...".
Let t0027 check for these warnings:
call create_file_in_repo() with additional parameters,
which will be used to call check_warning().
When a file has eol=lf or eol=crlf in .gitattributes, it is handled
as text and should be normalized.
Add missing test cases in t0027.

Thinning a repository
Hi everyone, Is there a quick way to reproduce the effect of a shallow clone on a local repository that doesn't involve filter-branch and/or re-clone? My motivation is to reduce the local size of repositories I'm only following, by trimming the history without prejudice to a [N] set of last commits. It feels stupid that the quickest way I'm aware of right now to achieve this is to "git clone --depth N ..." again. filter-branch is ridiculously slow, as it iterates through history. I've tried using graft points, but the combination of: echo [sha] > .git/info/grafts git reflog expire --expire=0 --all git repack -Ad doesn't really save any space and/or reduce the object count as I would expect. It means there's probably still reachable? I'd really love to have a 'git thin [depth]' subcommand to perform the above however. I don't really want to have to iterate through refs just to check if they are still reachable within [n] commits just to delete them. Thanks for any pointer. -- To unsubscribe from this list: send the line "unsubscribe git" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html

Indeed, suggesting people to add an alias does not solve the
discoverability issue. git rev-parse --show-toplevel is not just long,
it's just not the place where people would look for (it's neither about
revision nor about parsing, so clearly, "rev-parse" is not a good place
to host the feature in the UI).
If we were to rewrite Git from scratch, then I would be all for having a
"git root" command. Given that we already have rev-parse
--show-toplevel, and that we'll have to keep it anyway for backward
compatibility, I'm a bit more hesitant ("Git is hard to use because it
doesn't have enough commands" is not a complain I hear so often ;-) ),
but still mostly positive.
If we go this way, then the documentation must be updated too. I think
the doc should still recommend "git rev-parse --show-toplevel" for
scripting until Git versions implementing "git root" are widely deployed
enough.
Also, there are other options of git rev-parse which should be dealt
with: at least --show-cdup (could be eg. "git root --relative") and
--show-prefix, but probably also others from the "Options for Files" in
the man of git-rev-parse.

[PATCH 2/3] ls-tree: remove path filtering logic in show_tree
ls-tree uses read_tree_recursive() which already does path filtering
using pathspec. No need to filter one more time based on prefix
only. "ls-tree ../somewhere" does not work because of
this. write_name_quotedpfx() can now be retired because nobody else
uses it.

[PATCH 15/19] list-files: do not show duplicate cached entries
With the current show_files() "list-files -tcm" will show
foo.c
M foo.c
The first item is redundant. If "foo.c" is modified, we know it's in
the cache. Introduce show_files_compact to do that because ls-files is
plumbing and scripts may already depend on current display behavior.
Another difference in show_files_compact() is it does not show
skip-worktree (aka outside sparse checkout) entries anymore, which
makes sense in porcelain context.

[PATCH 14/19] list-files: sort output and remove duplicates
When you mix different file types, with ls-files you may get separate
listing. For example, "ls-files -cm" will show file "abc" twice: one
as part of cached list, one of modified list. With "ls" (and this
patch) they will be in a single sorted list (easier for the eye).
Duplicate entries are also removed. Note that display content is
compared, so if you have "-t" on, or you color file types differently,
you will get duplicate textual entries. This is good imo.

[PATCH 17/19] list-files: add -F/--classify
This appends an indicator after the file name if it's executable, a
directory and so on, like in GNU ls. In fact append_indicator() is a
rewrite from get_type_indicator() in coreutils.git commit
7326d1f1a67edf21947ae98194f98c38b6e9e527.

[PATCH 01/19] ls_colors.c: add $LS_COLORS parsing code
Reusing color settings from $LS_COLORS could give a native look and
feel on file coloring.
This code is basically from coreutils.git [1], rewritten to fit Git.
As this is from GNU ls, the environment variable CLICOLOR is not
tested. It is to be decided later whether we should ignore $LS_COLORS
if $CLICOLOR is not set on Mac or FreeBSD.
[1] commit 7326d1f1a67edf21947ae98194f98c38b6e9e527 file
src/ls.c. This is the last GPL-2 commit before coreutils turns to
GPL-3.

[PATCH 00/19] Add git-list-files
This is something else that's been sitting in my tree for a while now. It adds "git list-files", intended to be aliased as "ls" with your favourite display options. As you can guess it's a friendlier version (and pretty close to GNU ls) of ls-files. On one hand, I think this is a nice addition. On the other hand, code bloat.

I'm not Junio :) but I think the core changes are done. I wanted to
actually add watchman support on top of untracked cache as well to see
if it needs any more changes. I think I can see how it could be done
now (not easy, but not terribly hard). I'm going to resend soon to fix
some minor bugs (in a reroll that Junio has not picked up) and change
file format to be more compact.

[PATCH 34/34] git-common-dir: make "modules/" per-working-directory directory
From: Max Kirillov
Each working directory of main repository has its own working directory
of submodule, and in most cases they should be checked out to different
revisions. So they should be separated.
It looks logical to make submodule instances in different working
directories to reuse the submodule directory in the common dir of
the main repository, and probably this is how "checkout --to" should
initialize them called on the main repository, but they also should work
fine being completely separated clones.
Testfile t7410-submodule-checkout-to.sh demostrates the behavior.

The use case is auto fixup after a manual checkout move. - linked checkouts are supposed to update mtime of $R/gitdir.

If $R/locked exists and $R/gitdir's mtime is older than a really long limit, warn about old unused repo. - "git checkout --to" is supposed to make a hard link named $R/link pointing to the .git file on supported file systems to help detect the user manually deleting the checkout. If $R/link exists and its link count is greated than 1, the repo is kept.

[PATCH 33/34] checkout: do not fail if target is an empty directory
From: Max Kirillov
Non-recursive checkout creates empty directpries in place of submodules.
If then I try to "checkout --to" submodules there, it refuses to do so,
because directory already exists.
Fix by allowing checking out to empty directory. Add test and modify the
existing one so that it uses non-empty directory.

[PATCH 30/34] git_path(): keep "info/sparse-checkout" per work-tree
Currently git_path("info/sparse-checkout") resolves to
$GIT_COMMON_DIR/info/sparse-checkout in multiple worktree mode. It
makes more sense for the sparse checkout patterns to be per worktree,
so you can have multiple checkouts with different parts of the tree.
With this, "git checkout --to " on a sparse checkout will create
as a full checkout. Which is expected, it's how a new checkout
is made. The user can reshape the worktree afterwards.

[PATCH 31/34] checkout: don't require a work tree when checking out into a new one
From: Dennis Kaarsemaker
For normal use cases, it does not make sense for 'checkout' to work on
a bare repository, without a worktree. But "checkout --to" is an
exception because it _creates_ a new worktree. Allow this option to
run on bare repositories.
People who check out from a bare repository should remember that
core.logallrefupdates is off by default and it should be turned back
on. `--to` cannot do this automatically behind the user's back because
some user may deliberately want no reflog.
For people interested in repository setup/discovery code,
is_bare_repository_cfg (aka "core.bare") is unchanged by this patch,
which means 'true' by default for bare repos. Fortunately when we get
the repo through a linked checkout, is_bare_repository_cfg is never
used. So all is still good.

[PATCH 22/34] checkout: support checking out into a new working directory
"git checkout --to" sets up a new working directory with a .git file pointing to $GIT_DIR/worktrees/. It then executes "git checkout" again on the new worktree with the same arguments except "--to" is taken out. The second checkout execution, which is not contaminated with any info from the current repository, will actually check out and everything that normal "git checkout" does.

[PATCH 19/34] setup.c: support multi-checkout repo setup
The repo setup procedure is updated to detect $GIT_DIR/commondir and
set $GIT_COMMON_DIR properly.
The core.worktree is ignored when $GIT_COMMON_DIR is set. This is
because the config file is shared in multi-checkout setup, but
checkout directories _are_ different. Making core.worktree effective
in all checkouts mean it's back to a single checkout.

[PATCH 11/34] $GIT_COMMON_DIR: a new environment variable
This variable is intended to support multiple working directories attached to a repository. Such a repository may have a main working directory, created by either "git init" or "git clone" and one or more linked working directories. These working directories and the main repository share the same repository directory. In linked working directories, $GIT_COMMON_DIR must be defined to point to the real repository directory and $GIT_DIR points to an unused subdirectory inside $GIT_COMMON_DIR. File locations inside the repository are reorganized from the linked worktree view point: - worktree-specific such as HEAD, logs/HEAD, index, other top-level refs and unrecognized files are from $GIT_DIR. - the rest like objects, refs, info, hooks, packed-refs, shallow... are from $GIT_COMMON_DIR (except info/sparse-checkout, but that's a separate patch) Scripts are supposed to retrieve paths in $GIT_DIR with "git rev-parse --git-path", which will take care of "$GIT_DIR vs $GIT_COMMON_DIR" business. The redirection is done by git_path(), git_pathdup() and strbuf_git_path(). The selected list of paths goes to $GIT_COMMON_DIR, not the other way around in case a developer adds a new worktree-specific file and it's accidentally promoted to be shared across repositories (this includes unknown files added by third party commands) The list of known files that belong to $GIT_DIR are: ADD_EDIT.patch BISECT_ANCESTORS_OK BISECT_EXPECTED_REV BISECT_LOG BISECT_NAMES CHERRY_PICK_HEAD COMMIT_MSG FETCH_HEAD HEAD MERGE_HEAD MERGE_MODE MERGE_RR NOTES_EDITMSG NOTES_MERGE_WORKTREE ORIG_HEAD REVERT_HEAD SQUASH_MSG TAG_EDITMSG fast_import_crash_* logs/HEAD next-index-* rebase-apply rebase-merge rsync-refs-* sequencer/* shallow_* Path mapping is NOT done for git_path_submodule(). Multi-checkouts are not supported as submodules.

[PATCH 08/34] reflog: avoid constructing .lock path with git_path
Among pathnames in $GIT_DIR, e.g. "index" or "packed-refs", we want to
automatically and silently map some of them to the $GIT_DIR of the
repository we are borrowing from via $GIT_COMMON_DIR mechanism. When
we formulate the pathname for its lockfile, we want it to be in the
same location as its final destination. "index" is not shared and
needs to remain in the borrowing repository, while "packed-refs" is
shared and needs to go to the borrowed repository.
git_path() could be taught about the ".lock" suffix and map
"index.lock" and "packed-refs.lock" the same way their basenames are
mapped, but instead the caller can help by asking where the basename
(e.g. "index") is mapped to git_path() and then appending ".lock"
after the mapping is done.

[PATCH 06/34] git_path(): be aware of file relocation in $GIT_DIR
We allow the user to relocate certain paths out of $GIT_DIR via
environment variables, e.g. GIT_OBJECT_DIRECTORY, GIT_INDEX_FILE and
GIT_GRAFT_FILE. Callers are not supposed to use git_path() or
git_pathdup() to get those paths. Instead they must use
get_object_directory(), get_index_file() and get_graft_file()
respectively. This is inconvenient and could be missed in review (for
example, there's git_path("objects/info/alternates") somewhere in
sha1_file.c).
This patch makes git_path() and git_pathdup() understand those
environment variables. So if you set GIT_OBJECT_DIRECTORY to /foo/bar,
git_path("objects/abc") should return /foo/bar/abc. The same is done
for the two remaining env variables.
"git rev-parse --git-path" is the wrapper for script use.
This patch kinda reverts a0279e1 (setup_git_env: use git_pathdup
instead of xmalloc + sprintf - 2014-06-19) because using git_pathdup
here would result in infinite recursion:
setup_git_env() -> git_pathdup("objects") -> .. -> adjust_git_path()
-> get_object_directory() -> oops, git_object_directory is NOT set
yet -> setup_git_env()
I wanted to make git_pathdup_literal() that skips adjust_git_path().
But that won't work because later on when $GIT_COMMON_DIR is
introduced, git_pathdup_literal("objects") needs adjust_git_path() to
replace $GIT_DIR with $GIT_COMMON_DIR.

[PATCH 04/34] path.c: rename vsnpath() to do_git_path()
The name vsnpath() gives an impression that this is general path
handling function. It's not. This is the underlying implementation of
git_path(), git_pathdup() and strbuf_git_path() which will prefix
$GIT_DIR in the result string.

[PATCH 00/34] nd/multiple-work-trees reroll
This is rebased so the diff below (against the version on Junio's
repo) is only approximate. Changes include test fixes for Windows
port, $GIT_COMMON_DIR and $GIT_DIR/modules problems with submodules.
Patch 03/34 is rewritten to touch less in refs.c to reduce conflicts.
A lot of changes there are just revert.

[PATCH 02/34] path.c: make get_pathname() call sites return const char *
Before the previous commit, get_pathname returns an array of PATH_MAX
length. Even if git_path() and similar functions does not use the
whole array, git_path() caller can, in theory.
After the commit, get_pathname() may return a buffer that has just
enough room for the returned string and git_path() caller should never
write beyond that.
Make git_path(), mkpath() and git_path_submodule() return a const
buffer to make sure callers do not write in it at all.
This could have been part of the previous commit, but the "const"
conversion is too much distraction from the core changes in path.c.

[PATCH 03/34] git_snpath(): retire and replace with strbuf_git_path()
In the previous patch, git_snpath() is modified to allocate a new
strbuf buffer because vsnpath() needs that. But that makes it
awkward because git_snpath() receives a pre-allocated buffer from
outside and has to copy data back. Rename it to strbuf_git_path()
and make it receive strbuf directly.
Using git_path() in update_refs_for_switch() which used to call
git_snpath() is safe because that function and all of its callers do
not keep any pointer to the round-robin buffer pool allocated by
get_pathname().

[PATCH 01/34] path.c: make get_pathname() return strbuf instead of static buffer
We've been avoiding PATH_MAX whenever possible. This patch makes
get_pathname() return a strbuf and updates the callers to take
advantage of this. The code is simplified as we no longer need to
worry about buffer overflow.
vsnpath() behavior is changed slightly: previously it always clears
the buffer before writing, now it just appends. Fortunately this is a
static function and all of its callers prepare the buffer properly:
git_path() gets the buffer from get_pathname() which resets the
buffer, the remaining call sites start with STRBUF_INIT'd buffer.
