fsmonitor: read entirety of watchman output

In Perl, setting $/ sets the string that is used as the "record
separator," which sets the boundary that the `<>` construct reads to.
Setting `local $/ = 0666;` evaluates the octal, getting 438, and
stringifies it.  Thus, the later read from `<CHLD_OUT>` stops as soon
as it encounters the string "438" in the watchman output, yielding
invalid JSON; repositories containing filenames with SHA1 hashes are
able to trip this easily.

Set `$/` to undefined, thus slurping all output from watchman.  Also
close STDIN which is provided to watchman, to better guarantee that we
cannot deadlock with watchman while both attempting to read.

6 years agofsmonitor: add a performance test
Ben Peart [Fri, 22 Sep 2017 16:35:48 +0000 (12:35 -0400)] 
fsmonitor: add a performance test

Add a test utility (test-drop-caches) that flushes all changes to disk
then drops file system cache on Windows, Linux, and OSX.

Add a perf test (p7519-fsmonitor.sh) for fsmonitor.

By default, the performance test will utilize the Watchman file system
monitor if it is installed.  If Watchman is not installed, it will use a
dummy integration script that does not report any new or modified files.
The dummy script has very little overhead which provides optimistic results.

The performance test will also use the untracked cache feature if it is
available as fsmonitor uses it to speed up scanning for untracked files.

There are 4 environment variables that can be used to alter the default
behavior of the performance test:

GIT_PERF_7519_UNTRACKED_CACHE: used to configure core.untrackedCache
GIT_PERF_7519_SPLIT_INDEX: used to configure core.splitIndex
GIT_PERF_7519_FSMONITOR: used to configure core.fsmonitor
GIT_PERF_7519_DROP_CACHE: if set, the OS caches are dropped between tests

The big win for using fsmonitor is the elimination of the need to scan the
working directory looking for changed and untracked files. If the file
information is all cached in RAM, the benefits are reduced.

Test that if the fsmonitor extension doesn't tell git about a change, it
doesn't discover it on its own.  This ensures git is honoring the
extension and that we get the performance benefits desired.

Three test integration scripts are provided:

fsmonitor-all - marks all files as dirty
fsmonitor-none - marks no files as dirty
fsmonitor-watchman - integrates with Watchman with debug logging

To run tests in the test suite while utilizing fsmonitor:

First copy t/t7519/fsmonitor-all to a location in your path and then set
GIT_FORCE_PRELOAD_TEST=true and GIT_FSMONITOR_TEST=fsmonitor-all and run
your tests.

Note: currently when using the test script fsmonitor-watchman on
Windows, many tests fail due to a reported but not yet fixed bug in
Watchman where it holds on to handles for directories and files which
prevents the test directory from being cleaned up properly.

When the index is read from disk, the fsmonitor index extension is used
to flag the last known potentially dirty index entries. The registered
core.fsmonitor command is called with the time the index was last
updated and returns the list of files changed since that time. This list
is used to flag any additional dirty cache entries and untracked cache
directories.

We can then use this valid state to speed up preload_index(),
ie_match_stat(), and refresh_cache_ent() as they do not need to lstat()
files to detect potential changes for those entries marked

invalidate the cache only for those directories that have been
identified as having potential changes.

To keep the CE_FSMONITOR_VALID state accurate during git operations;
when git updates a cache entry to match the current state on disk,
it will now set the CE_FSMONITOR_VALID bit.

Inversely, anytime git changes a cache entry, the CE_FSMONITOR_VALID bit
is cleared and the corresponding untracked cache directory is marked
invalid.

6 years agobranch: fix branch renaming not updating HEADs correctly
Nguyễn Thái Ngọc Duy [Thu, 24 Aug 2017 10:41:24 +0000 (17:41 +0700)] 
branch: fix branch renaming not updating HEADs correctly

There are two bugs that sort of work together and cause
problems. Let's start with one in replace_each_worktree_head_symref.

Before fa099d2322 (worktree.c: kill parse_ref() in favor of
refs_resolve_ref_unsafe() - 2017-04-24), this code looks like this:

    if (strcmp(oldref, worktrees[i]->head_ref))
            continue;
    set_worktree_head_symref(...);

After fa099d2322, it is possible that head_ref can be NULL. However,
the updated code takes the wrong exit. In the error case (NULL
head_ref), we should "continue;" to the next worktree. The updated
code makes us _skip_ "continue;" and update HEAD anyway.

The NULL head_ref is triggered by the second bug in add_head_info (in
the same commit). With the flag RESOLVE_REF_READING, resolve_ref_unsafe()
will abort if it cannot resolve the target ref. For orphan checkouts,
HEAD always points to an unborned branch, resolving target ref will
always fail. Now we have NULL head_ref. Now we always update HEAD.

Correct the logic in replace_ function so that we don't accidentally
update HEAD on error. As it turns out, correcting the logic bug above
breaks branch renaming completely, thanks to the second bug.

"git branch -[Mm]" does two steps (on a normal checkout, no orphan!):

 - rename the branch on disk (e.g. refs/heads/abc to refs/heads/def)
 - update HEAD if it points to the branch being renamed.

At the second step, since the branch pointed to by HEAD (e.g. "abc") no
longer exists on disk, we run into a temporary orphan checkout situation
that has been just corrected to _not_ update HEAD. But we need to update
HEAD since it's not actually an orphan checkout. We need to update HEAD
to move out of that orphan state.

Correct add_head_info(), remove RESOLVE_REF_READING flag. With the flag
gone, we should always return good "head_ref" in orphan checkouts (either
temporary or permanent). With good head_ref, things start to work again.

convert: display progress for filtered objects that have been delayed

In 2841e8f ("convert: add "status=delayed" to filter process protocol",
2017-06-30) we taught the filter process protocol to delayed responses.
These responses are processed after the "Checking out files" phase.
If the processing takes noticeable time, then the user might think Git
is stuck.

Display the progress of the delayed responses to let the user know that
Git is still processing objects. This works very well for objects that
can be filtered quickly. If filtering of an individual object takes
noticeable time, then the user might still think that Git is stuck.
However, in that case the user would at least know what Git is doing.

It would be technical more correct to display "Checking out files whose
content filtering has been delayed". For brevity we only print
"Filtering content".

The finish_delayed_checkout() call was moved below the stop_progress()
call in unpack-trees.c to ensure that the "Checking out files" progress
is properly stopped before the "Filtering content" progress starts in
finish_delayed_checkout().
