12 years agowrite_head_info(): handle "extra refs" locally
Michael Haggerty [Fri, 6 Jan 2012 14:12:33 +0000 (15:12 +0100)]
write_head_info(): handle "extra refs" locally

The old code basically did:

     generate array of SHA1s for alternate refs
     for each unique SHA1 in array:
         add_extra_ref(".have", sha1)
     for each ref (including real refs and extra refs):
         show_ref(refname, sha1)

But there is no need to stuff the alternate refs in extra_refs; we can
call show_ref() directly when iterating over the array, then handle
real refs separately.  So change the code to:

     generate array of SHA1s for alternate refs
     for each unique SHA1 in array:
         show_ref(".have", sha1)
     for each ref (this now only includes real refs):
         show_ref(refname, sha1)

revert --abort: do not leave behind useless sequencer-old directory

The "git cherry-pick --abort" command currently renames the
.git/sequencer directory to .git/sequencer-old instead of removing it
on success due to an accident.  cherry-pick --abort is designed to
work in three steps:

 1) find which commit to roll back to
 2) call "git reset --merge <commit>" to move to that commit
 3) remove the .git/sequencer directory

But the careless author forgot step 3 entirely.  The only reason the
command worked anyway is that "git reset --merge <commit>" renames the
.git/sequencer directory as a secondary effect --- after moving to
<commit>, or so the logic goes, it is unlikely but possible that the
caller of git reset wants to continue the series of cherry-picks that
was in progress, so git renames the sequencer state to
.git/sequencer-old to be helpful while allowing the cherry-pick to be
resumed if the caller did not want to end the sequence after all.

By running "git cherry-pick --abort", the operator has clearly
indicated that she is not planning to continue cherry-picking.  Remove
the (renamed) .git/sequencer directory as intended all along.

to produce a copy of the patch to refer to while resolving conflicts:

$ git revert 2eceb2a8
error: could not revert 2eceb2a8... awesome, buggy feature
$ git show -R REVERT_HEAD >the-patch
$ edit $(git diff --name-only)

for cases like this.  This also makes it possible for scripts to

sources of an unmerged index.

After successfully committing, resetting with "git reset", or moving

Good.  However, the error message on attempting step 3 is more

On cygwin, test number 21 of t3200-branch.sh (git branch -m q q2
without config should succeed) fails. The failure involves the
functions from path.c which parcel out internal static buffers
from the git_path() and mkpath() functions.

In particular, the rename_ref() function calls safe_create_leading\
_directories() with a filename returned by git_path("logs/%s", ref).
safe_create_leading_directories(), in turn, calls stat() on each
element of the path it is given. On cygwin, this leads to a call
to git_config() for each component of the path, since this test
explicitly removes the config file. git_config() calls mkpath(), so
on the fourth component of the path, the original buffer passed
into the function is overwritten with the config filename.

t5501-*.sh: Fix url passed to clone in setup test

In particular, the url passed to git-clone has an extra '/' given
after the 'file://' schema prefix, thus:

    git clone --reference=original "file:///$(pwd)/original one

Once the prefix is removed, the remainder of the url looks something
like "//home/ramsay/git/t/...", which is then interpreted as an
network path. This then results in a "Permission denied" error, like
so:

    ramsay $ ls //home
    ls: cannot access //home: No such host or network path
    ramsay $ ls //home/ramsay
    ls: cannot access //home/ramsay: Permission denied
    ramsay $

In order to fix the problem, we simply remove the extraneous '/'
character from the url.

Makefile: add option to disable automatic dependency generation

Now that the COMPUTE_HEADER_DEPENDENCIES feature is turned on
automatically for compilers that support it (see v1.7.8-rc0~142^2~1,
2011-08-18), there is no easy way to force it off.  For example,
setting COMPUTE_HEADER_DEPENDENCIES to the empty string in config.mak
just tells the makefile to treat it as undefined and run a test
command to see if the -MMD option is supported.

So allow setting COMPUTE_HEADER_DEPENDENCIES=no to explicitly force
the feature off.  The new semantics:

 - "yes" means to explicitly enable the feature
 - "no" means to disable it
 - "auto" means to autodetect

The default is still "auto".  Any value other than these three will
cause the build to error out with a descriptive message so typos and
stale settings in config.mak don't result in mysterious behavior.

Makefile:1278: *** please set COMPUTE_HEADER_DEPENDENCIES to
yes, no, or auto (not "1").  Stop.

So now when someone using a compiler without -MMD support reports
trouble building git, you can reproduce it by running "make
COMPUTE_HEADER_DEPENDENCIES=no".
