RE: Feature Request - Hide ignored files before checkout

2012-12-09 Thread Matthew Ciancio
I'm glad we are on the same page now and thanks for bringing in others.

 Not wanting the files in the repository seems to be in conflict with the
desire to have them under its control (i.e., disappear/reappear behavior.) 
Sorry, when I said I didn't want them in the repository, I meant I wanted
them there (in the repository folder), but not within Git commit logs and
not being tracked, etc.
Committing binary/OS specific files just doesn't sit right with me and I am
sure many others.

... but why do you need them to disappear?  Why not just put them somewhere
where they can be used when needed and left alone when not?
I could do that (keep them in a folder that will be left alone), but in my
specific case it would mean the executable files (ignored files placed in
this new folder) will not execute because of the change in location and
hence would require a lot of code change to suit.

From my perspective I don't see the harm in having this as a new feature
(via flags in the .gitignore file, if you don't want to make it default
behaviour). Is there some reason I don't know about, maybe to do with the
Git source code?

 Hi Chris,

 Yes, I don't think I have explained myself well enough.

 When I say disappear I do not mean get deleted, I mean: go out of 
 view just like foo.txt does, as it is committed to branchB and not 
 merged into branchA.

 So I am saying that I think .gitignored files should behave partly 
 like committed and un-merged files, in the sense that they disappear 
 when checking out to a different branch.
 I don't want to commit these files (which would give me the behaviour 
 I want), because they are binary/OS specific and really do not belong 
 in the repository, BUT I need them to run/build certain committed files.

 To be concrete: I want ignore.txt to be ignored in branchB and hence 
 disappear (in the same way that foo.txt will), when checking out to
branchA.
 When I checkout back to branchB I want ignore.txt to reappear (in the 
 same way that foo.txt will).

 I understand why this behaviour is not happening (because my 
 .gitignore files are different between the branches), but I am saying 
 that I would like to have the option to keep my .gitignore'd files 
 local to the branch they are in.

 E.g. I currently have a branch with all these binary files that are 
 required to run an application on my OS, but when I checkout to 
 another branch I do not need or want those binary files anymore (at 
 least not until I checkout back into the branch I just came from).

 Please tell me if that still doesn't make sense.

Hi Matthew,

Cc'ing the list to benefit from the review of others.

Not wanting the files in the repository seems to be in conflict with the
desire to have them under its control (i.e., disappear/reappear
behavior.)  I understand not wanting to commit dependencies, but why do you
need them to disappear?  Why not just put them somewhere where they can be
used when needed and left alone when not?

If you do want this behavior, it seems like you should just commit the files
on the respective branch.  Maybe someone else will have a better idea,
though.

Chris

Re: Feature Request - Hide ignored files before checkout

2012-12-09 Thread Junio C Hamano
Chris Rorvick ch...@rorvick.com writes:

 It's not in branchA, it's just no longer ignored because your changes
 to .gitignore were effectively reverted by jumping back to the commit
 that branchA points to.
 ...
 hide/reappear is the equivalent to saying deleted/created in the
 case of a tracked file in your working tree.  But how would Git cause
 an untracked file to reappear?  By definition, it doesn't know
 anything about the file.

Nicely explained. To make something simply disappear, you could
remove it, but that is obviously not enough to make it reappear.  It
has to be stashed away somewhere before it gets removed, and in the
context of (any) SCM, that is done by committing.

You may have Mac and Windows branches, each of which needs to link
with vendor supplied object file blackbox.o with the rest of the
source.  It is understandable if a project does not want to mix such
platform specific black box binaries in the history of the source.

But that does not necessarily mean the project can totally ignore
what specific black box binary was meant to be used with the rest of
the source.

After you released the v1.0 of your product for both Macintosh and
Windows, the vendor may supply updated versions of the blackbox.o
binary for these platforms, and you would start working toward v1.1
of your product using these updated copies of objects.  Then you
find problems in the released v1.0 software.  Without keeping track
of which version of the object was used to build the released v1.0,
you cannot diagnose, build and test a maintenance update v1.0.1.

The project may add new Macintosh (or Windows) developers.  You can
tell new Macintosh developers to clone and checkout mac branch, and
in the same e-mail, give them the untracked blackbox.o file for that
platform, but you have to rely on human not making mistakes (you may
mistakenly send Windows version of blackbox.o to him, you may send
stale Macintosh version, the developer may misplace the new one and
keep using the stale one, etc. etc.).

Some people commit blackbox.o on each platform-specific branch, or
all branches share blackbox-win.o and blackbox-mac.o, only one of
which is used at any given branch, for this exact reason.

The project, for licensing reasons, may not have rights to
distribute such a blackbox object file along with its sources, but
the vendor of the blackbox object may allow individual developer to
download and link it from vendor's site.  In such a case, the
project would not want to (and is not allowed to) commit such object
file.  One approach I have seen used in such a case is to arrange
the build procedure so that these individual developers can drop
such an external object next to the project directory, and refer to
it as ../blackbox.o when linking.

So these files are moved away from the working tree upon checking
another branch out, and moved back into the working tree upon
checking out this branch is pretty much outside the scope of any
SCM.  It is not very interesting, as it is not necessary to solve
any real world problem.

Of course, the users can do whatever moving/copying/renaming of
untracked files in their post-checkout hook to be run when a new
branch is checked out.

Łukasz Stelmach stl...@poczta.fm writes:

 Enable gitk read and write repository specific configuration

files and update them.

So I suspect that this may introduce more trouble than it is worth
for users and should not be sold with a This is very useful label.
At best, it is This may be useful; otherwise the feature may end
up harming our users.  I'd phrase it without judging if it is good
or bad for the users, perhaps like this:

This allows one to specify different views for different
repositories.

In any case, the filename .git/k may be _cute_, but I do not think
we would want to see:

$ ls .git
branchesconfig   HEAD   index  k objects
COMMIT_EDITMSG  description  hooks  info   logs  refs

It is too cryptic, unless the user _knows_ 'k' is for gitk.  I'd
call it $GIT_DIR/gitkconfig or something, if I were supportive for
this feature (which I am not enthusiastic, yet).

Could you clarify As a side effect a bit more?  Do you mean

Earlier strbuf_add_wrapped_text() ended its output with a

With the bug fixed, the function never ends its output with a

Re: [PATCH] git-clean: Display more accurate delete messages

2012-12-09 Thread Zoltan Klinger
 Hrm, following your discussion (ellided above), I would have
 expected that you would show

 Removing directory foo/bar
 Removing untracked_file1

 Also it would be nice to have warnings about undeleted directories since this 
 git
 clean behavior (or the work around to pass -f twice) is not documented.
 Without a warning you would probably miss that something was _not_ deleted.

Thanks for the feedback. I think you're right. Showing 'foo/bar/bar.txt' in
the list when 'foo/bar/' directory has been successfully deleted is just noise.

Would like to get some more feedback on the proposed output in case of
 (1) an untracked subdirectory with multiple files where at least one of them
 cannot be removed.
 (2) reporting ignored untracked git subdirectories

Suppose we have a repo like the one below:
  test.git/
|-- tracked_file
|-- untracked_file
|-- untracked_foo/
| |-- bar/
| | |-- bar.txt
| |-- emptydir/
| |-- frotz.git/
| | |-- frotx.txt
| |-- quux/
|   |-- failedquux.txt
|   |-- quux.txt
|-- untracked_unreadable_dir/
| |-- afile
|-- untracked_some.git/
  |-- some.txt

$ git clean -fd
Removing untracked_file
Removing untracked_foo/bar
Removing untracked_foo/emptydir
Removing untracked_foo/quux/quux.txt
warning: failed to remove untracked_foo/quux/failedquux.txt

warning: ignoring untracked git repository untracked_foo/frotz.git/
warning: ignoring untracked git repository untracked_some.git/
Use git clean --force --force to delete all untracked git repositories

$ # use forced remove
$ git clean --force --force -d

Removing untracked_foo/quux/quux.txt
Removing untracked_some.git/
warning: failed to remove untracked_foo/quux/failedquux.txt

Can you see any issues with the proposed output, wording above? If

Merging configuration from the global file (~/.gitk) is quite easy as

you need to (assume one keeps git repositoris below $HOME)

1. Enter a random repository
2. mv .git/gitk .git/gitk-local (see below)
3. Run gitk, configure fonts to your taste, save config (it will be
saved  globally)
4. mv .git/gitk-local .git/gitk

Now the font settings from ~/.gitk will be applied (and saved locally
when gitk exits) in every repository find(1) found.

 So I suspect that this may introduce more trouble than it is worth
 for users and should not be sold with a This is very useful label.
 At best, it is This may be useful;

I work with more than two dozen different repositories and saving the
list of branches I want to see upon startup is quite important for me.

 otherwise the feature may end
 up harming our users.  I'd phrase it without judging if it is good
 or bad for the users, perhaps like this:
 
 This allows one to specify different views for different
 repositories.

At present the code won't harm anyone not willing to get harmed. To make
gitk save the configuration locally user needs to create the
configuration file manually, outside of gitk, for example with touch(1)
(yes it may be empty).

 In any case, the filename .git/k may be _cute_, but I do not think
 we would want to see:
 
 $ ls .git
 branchesconfig   HEAD   index  k objects
 COMMIT_EDITMSG  description  hooks  info   logs  refs

I agree this was just to draw your attention ;-)

 It is too cryptic, unless the user _knows_ 'k' is for gitk.  I'd
 call it $GIT_DIR/gitkconfig or something, if I were supportive for
 this feature (which I am not enthusiastic, yet).

I think simply $GIT_DIR/gitk as in ~/.gitk is going to be fine.

 This is very useful if one uses different views for different

 ~/.gitk and make the views list needlessly long.

 I do not use gitk heavily myself, but I have a mixed feeling about
 this patch.
 
 I agree, I think this would be surprising to people who are used to
 the way gitk works now.

 I could imagine having a checkbox in the Edit-Preferences dialog to
 say Save configuration settings locally, and if you check that box,
 then it writes the configuration to .git/gitkconfig or whatever
 (having first saved that setting in the global ~/.gitk). 

No this isn't a good idea. When you choose to save configuration locally
it means you've alredy changed it to match your local needs and making
it global does not seem reasonable.

 But I think it should be an opt-in thing.

It is opt-in now definitely. One needs to create the local config file,
even an empty one, for gitk to choose it upon doquit/savestuff. I agree
a checkbox may be more convenient but is it opty (as in opt-in) enough?

Then, the checkbox should be added to both Preferences and Edit View
dialogs, anything more?

 In any case, the filename .git/k may be _cute_, but I do not think
 we would want to see:

Sure, let's vote:

empty value, thus disabling field splitting:

unset IFS

saved_IFS=$IFS
IFS=:

IFS=$saved_IFS
# no field splitting performed from now on!

Not sure how this is relevant for the Git codebase, but maybe it is
something worth reporting in the commit message of a proposed patch.

 hide/reappear is the equivalent to saying deleted/created in the 
 case of a tracked file in your working tree.  But how would Git cause 
 an untracked file to reappear?  By definition, it doesn't know 
 anything about the file.

Nicely explained. To make something simply disappear, you could remove it,
but that is obviously not enough to make it reappear.  It has to be stashed
away somewhere before it gets removed, and in the context of (any) SCM, that
is done by committing.

You may have Mac and Windows branches, each of which needs to link with
vendor supplied object file blackbox.o with the rest of the source.  It is
understandable if a project does not want to mix such platform specific
black box binaries in the history of the source.

But that does not necessarily mean the project can totally ignore what
specific black box binary was meant to be used with the rest of the source.

After you released the v1.0 of your product for both Macintosh and Windows,
the vendor may supply updated versions of the blackbox.o binary for these
platforms, and you would start working toward v1.1 of your product using
these updated copies of objects.  Then you find problems in the released
v1.0 software.  Without keeping track of which version of the object was
used to build the released v1.0, you cannot diagnose, build and test a
maintenance update v1.0.1.

The project may add new Macintosh (or Windows) developers.  You can tell new
Macintosh developers to clone and checkout mac branch, and in the same
e-mail, give them the untracked blackbox.o file for that platform, but you
have to rely on human not making mistakes (you may mistakenly send Windows
version of blackbox.o to him, you may send stale Macintosh version, the
developer may misplace the new one and keep using the stale one, etc. etc.).

Some people commit blackbox.o on each platform-specific branch, or all
branches share blackbox-win.o and blackbox-mac.o, only one of which is used
at any given branch, for this exact reason.

The project, for licensing reasons, may not have rights to distribute such a
blackbox object file along with its sources, but the vendor of the blackbox
object may allow individual developer to download and link it from vendor's
site.  In such a case, the project would not want to (and is not allowed to)
commit such object file.  One approach I have seen used in such a case is to
arrange the build procedure so that these individual developers can drop
such an external object next to the project directory, and refer to it as
../blackbox.o when linking.

So these files are moved away from the working tree upon checking another
branch out, and moved back into the working tree upon checking out this
branch is pretty much outside the scope of any SCM.  It is not very
interesting, as it is not necessary to solve any real world problem.

Of course, the users can do whatever moving/copying/renaming of untracked
files in their post-checkout hook to be run when a new branch is checked
out.

 The exit code doesn't seem to be documented.

Please make it so.

 Changing git reset $pathspec to return 0 on success, regardless of

Heh, true, the behavior according to my description does make sense,
it's just that my description was wrong; sorry :-(.

What git reset $pathspec returns is not whether HEAD differs from
index (as I wrote), but whether worktree differs from index. So
git reset and git reset . will return different exit codes if
there are changes in the worktree as compared to HEAD before the
invocation. I hope that's clearer.

 Problem: ignore.txt does not disappear like foo.txt does and is now just
 sitting in branchA (and now any other branch I checkout into).

 When I first started using Git, I genuinely thought this was a bug, because
 it seems so logical to me that ignore files should hide/reappear just like
 tracked files do, when switching branches.

Let me address this by asking a few questions; *why* do files
hide/reappear, what is the mechanism behind that and does it really
make sense to apply it to ignored files.

For each commit, git stores a snapshot of your files. When we switch
branches we are telling git to restore the previously saved snapshot
so we can work with those files. This means resetting the working
directory so that it looks like what we had committed; git will delete
files that were part of the current checked out snapshot but not the
new one, and create files that need to be created. As a convenience to
users, files that are not tracked are left 'as-is' when switching
branches.

So we see that in order to hide/reappear a file it has to be tracked
in a snapshot, and so has to be committed *somewhere*. An ignored file
is by definition not included in commits, and furthermore you hope to
keep these files out of your commit history.

 I have been told ways of circumventing this (using commits and un-commits OR
 using stash), but my reason for avoiding commits is: say you have binary/OS
 specific files which really do not belong in the commit logs (even locally)
 and hence should be ignored. What if you want those files in only one branch
 and not all?
 Stashing doesn't seem appropriate either, because it would get messy.

I am not sure how viable a suggestion this is, but perhaps you can
have two separate repositories, one tracking your standard branches,
and another tracking the ignored files. These repositories could be
kept in sync through submodules or some similar mechanism. This could
also allow you to, for example, publish the histories of these
independently, for example releasing the non-ignored repository
publicly.
I haven't heard of anyone doing this, but if you need to keep the
history clean it might be a way of achieving it.
I also don't know what the implications of checking out two
repositories into the same tree might be, or even if git would allow
it in general (maybe if you ignored everything belonging to the other
repository?) In any case, this solution could quickly become messy,
but if carefully controlled might solve your problem. Then again,
maybe you can achieve what you want using more 'traditional' git
workflows.

Yeah, it could be argued that in a very minor corner case showing
new and empty ones at the top might attract more attention to them,
but new and empty ones can stay inactive, so this change would be an
overall improvement for these two sites.  An alternative could be to
give the mtime of the git directory to the age field if there is no
commits in the repository, to sink the empty and inactive ones to
the bottom quickly while showing newly created ones at the top, but
it shouldn't make any practical difference.

   like:

sort {

  ? ($a-{$oi-{'key'}} = $b-{$oi-{'key'}})

my %order_sort = (
project = sub { $a-{'path'} cmp $b-{'path'} },
descr = sub { $a-{'descr_long'} cmp $b-{'descr_long'} },

age = sub { ... the num cmp with undef above ... },
);
if (!exists $order_sort{$order}) {

Yup.

Their numbers seem to be just 'any commit by the author, with
mailmap applied', and I am of two minds with it.  Counting without
shortlog --no-merges, depending on the management style of the
project, tends to credit the integrator too much.  Even though
vetting the patches and choosing when to merge the topics is a
significant contribution, it isn't *that* big compared to the work
done by the contributor who took initiative to scratch that itch.

With or without --no-merges, the big picture you can get out of
git shortlog -s -n --since=1.year does not change very much, but
the headline numbers give a wrong impression.

And of course, application of the mailmap is very important, if you
want to get meaningful numbers out of shortlog over a longer period.

Hrm.  update_one() is prepared to see a cache-tree whose entry count
is zero (see the context lines in the previous hunk) and the
invariant for the rest of the code is if 0 = entry_count, the
cached tree is valid; invalid cache-tree has -1 in entry_count.
More importantly, entry_count negated does not in general express

See above.  I am not fundamentally opposed to a change to redefine
entry_count so that it always maintains how many index entries the
subtree covers, even for invalidated subtree, but I do not think
this patch alone is sufficient to maintain such invariant.

Re: [PATCH] git-clean: Display more accurate delete messages

 Would like to get some more feedback on the proposed output in case of
  (1) an untracked subdirectory with multiple files where at least one of them
  cannot be removed.
  (2) reporting ignored untracked git subdirectories

 Suppose we have a repo like the one below:
   test.git/
 |-- tracked_file
 |-- untracked_file
 |-- untracked_foo/
 | |-- bar/
 | | |-- bar.txt
 | |-- emptydir/
 | |-- frotz.git/
 | | |-- frotx.txt
 | |-- quux/
 |   |-- failedquux.txt
 |   |-- quux.txt
 |-- untracked_unreadable_dir/
 | |-- afile
 |-- untracked_some.git/
   |-- some.txt

 $ git clean -fd
 Removing untracked_file
 Removing untracked_foo/bar
 Removing untracked_foo/emptydir
 Removing untracked_foo/quux/quux.txt
 warning: failed to remove untracked_foo/quux/failedquux.txt
 warning: failed to remove remove untracked_unreadable_dir/

remove remove is a typo, I presume.

 warning: ignoring untracked git repository untracked_foo/frotz.git/
 warning: ignoring untracked git repository untracked_some.git/

If you mean we report the topmost directory and nothing about
(recursive) contents in it if everything is removed successfully
(in other words, if we had subdirectories and files inside
untracked_foo/bar/ and we successfully removed all of them, the
above output does not change), it seems quite reasonable.

 Use git clean --force --force to delete all untracked git repositories

But I am not sure if this is ever sane.  Especially the one that
removes an embedded repository is suspicious.  git clean should
not ever touch it with or without --superforce or any other command.

I do not think trying to remove something that cannot be removed due
to filesystem permissions is sensible, either. We simply should treat
such a case a grave error and have the user sort things out, instead
of blindly attempt to chmod them ourselves (which may still fail).

Thanks.
