2017-08-26Merge branch 'tb/apply-with-crlf'Libravatar Junio C Hamano1-6/+27
"git apply" that is used as a better "patch -p1" failed to apply a taken from a file with CRLF line endings to a file with CRLF line endings. The root cause was because it misused convert_to_git() that tried to do "safe-crlf" processing by looking at the index entry at the same path, which is a nonsense---in that mode, "apply" is not working on the data in (or derived from) the index at all.

2017-08-23merge: save merge state earlierLibravatar Michael J Gruber1-0/+15
If the `git merge` process is killed while waiting for the editor to finish, the merge state is lost but the prepared merge msg and tree is kept. So, a subsequent `git commit` creates a squashed merge even when the user asked for proper merge commit originally. Demonstrate the problem with a test crafted after the in t7502. The test requires EXECKEEPSPID (thus does not run under MINGW). Save the merge state earlier (in the non-squash case) so that it does not get lost. This makes the test pass.

2017-08-22rerere: allow approxidate in gc.rerereResolved/gc.rerereUnresolvedLibravatar Junio C Hamano1-0/+2
These two configuration variables are described in the documentation to take an expiry period expressed in the number of days: gc.rerereResolved:: Records of conflicted merge you resolved earlier are kept for this many days when 'git rerere gc' is run. The default is 60 days. gc.rerereUnresolved:: Records of conflicted merge you have not resolved are kept for this many days when 'git rerere gc' is run. The default is 15 days. There is no strong reason not to allow a more general "approxidate" expiry specification, e.g. "5.days.ago", or "never". Rename the config_get_expiry() helper introduced in the previous step to git_config_get_expiry_in_days() and move it to a more generic place, config.c, and use date.c::parse_expiry_date() to do so. Give it an ability to allow the caller to tell among three cases (i.e. there is no "gc.rerereResolved" config, there is and it is correctly parsed into the *expiry variable, and there was an error in parsing the given value). The current caller can work correctly without using the return value, though. In the future, we may find other variables that only allow an integer that specifies "this many days" or other unit of time, and when it happens we may need to drop "_days" suffix from the name of the function and instead pass the "scale" value as another parameter. But this will do for now. Signed-off-by: Junio C Hamano <gitster@pobox.com>
2017-08-22t4200: parameterize "rerere gc" custom expiry testLibravatar Junio C Hamano1-25/+33
The test creates a rerere database entry that is two days old, and tries to expire with three different custom expiry configuration (keep ones less than 5 days old, keep ones used less than 5 days ago, and expire everything right now). We'll be introducing a different way to spell the same "5 days" and "right now" parameter in a later step; parameterize the test to make it easier to test the new spelling when it happens.

2017-08-22t4200: make "rerere gc" test more robustLibravatar Junio C Hamano1-5/+14
The test blindly trusted that there may be _some_ entries left in the rerere database, and used them by updating their timestamps to see if the gc threshold variables are honoured correctly. This won't work if there is no entry in the database when the test begins. Instead, clear the rerere database, and populate it with a few known entries (which are bogus, but for the purpose of testing "garbage collection", it does not matter---we want to make sure we collect old cruft, even if the files are corrupt rerere database entries), and use them for the expiry test.

2017-08-19apply: file commited with CRLF should roundtrip diff and applyLibravatar Torsten Bögershausen1-6/+27
When a file had been commited with CRLF but now .gitattributes say "* text=auto" (or core.autocrlf is true), the following does not roundtrip, `git apply` fails: printf "Added line\r\n" >>file && git diff >patch && git checkout -- . && git apply patch Before applying the patch, the file from working tree is converted into the index format (clean filter, CRLF conversion, ...). Here, when commited with CRLF, the line endings should not be converted. Note that `git apply --index` or `git apply --cache` doesn't call convert_to_git() because the source material is already in index format. Analyze the patch if there is a) any context line with CRLF, or b) if any line with CRLF is to be removed. In this case the patch file `patch` has mixed line endings, for a) it looks like this: diff --git a/one b/one index 533790e..c30dea8 100644 --- a/one +++ b/one @@ -1 +1,2 @@ a\r +b\r And for b) it looks like this: diff --git a/one b/one index 533790e..485540d 100644 --- a/one +++ b/one @@ -1 +1 @@ -a\r +b\r If `git apply` detects that the patch itself has CRLF, (look at the line " a\r" or "-a\r" above), the new flag crlf_in_old is set in "struct patch" and two things will happen: - read_old_data() will not convert CRLF into LF by calling convert_to_git(..., SAFE_CRLF_KEEP_CRLF); - The WS_CR_AT_EOL bit is set in the "white space rule", CRLF are no longer treated as white space. While at there, make it clear that read_old_data() in apply.c knows what it wants convert_to_git() to do with respect to CRLF. In fact, this codepath is about applying a patch to a file in the filesystem, which may not exist in the index, or may exist but may not match what is recorded in the index, or in the extreme case, we may not even be in a Git repository. If convert_to_git() peeked at the index while doing its work, it *would* be a bug. Pass NULL instead of &the_index to convert_to_git() to make sure we catch future bugs to clarify this. Update the test in t4124: split one test case into 3: - Detect the " a\r" line in the patch - Detect the "-a\r" line in the patch - Use LF in repo and CLRF in the worktree.

The '--set-upstream' option of branch was deprecated in b347d06b ("branch: deprecate --set-upstream and show help if we detect possible mistaken use", 2012-08-30) and has been planned for removal ever since. In order to prevent "--set-upstream" on a command line from being taken as an abbreviated form of "--set-upstream-to", explicitly catch "--set-upstream" option and die, instead of just removing it from the list of options. Before this change, an attempt to use "--set-upstream" resulted in: $ git branch * master $ git branch --set-upstream origin/master The --set-upstream flag is deprecated and will be removed. Consider using --track or --set-upstream-to Branch origin/master set up to track local branch master. $ echo $? 0 $ git branch * master origin/master With this change, the behaviour becomes like this: $ git branch * master $ git branch --set-upstream origin/master fatal: the '--set-upstream' option is no longer supported.

2017-08-16diff: define block by number of alphanumeric charsLibravatar Jonathan Tan1-69/+157
The existing behavior of diff --color-moved=zebra does not define the minimum size of a block at all, instead relying on a heuristic applied later to filter out sets of adjacent moved lines that are shorter than 3 lines long. This can be confusing, because a block could thus be colored as moved at the source but not at the destination (or vice versa), depending on its neighbors. Instead, teach diff that the minimum size of a block is 20 alphanumeric characters, the same heuristic used by "git blame". This allows diff to still exclude uninteresting lines appearing on their own (such as those solely consisting of one or a few closing braces), as was the intention of the adjacent-moved-line heuristic. This requires a change in some tests in that some of their lines are no longer considered to be part of a block, because they are too short.

2017-08-15t1002: stop using sum(1)Libravatar René Scharfe2-35/+35
sum(1) is a command for calculating checksums of the contents of files. It was part of early editions of Unix ("Research Unix", 1972/1973, [1]). cksum(1) appeared in 4.4BSD (1993) as a replacement [2], and became part of POSIX.1-2008 [3]. OpenBSD 5.6 (2014) removed sum(1). We only use sum(1) in t1002 to check for changes in three files. On MinGW we use md5sum(1) instead. We could switch to the standard command cksum(1) for all platforms; MinGW comes with GNU coreutils now, which provides sum(1), cksum(1) and md5sum(1). Use our standard method for checking for file changes instead: test_cmp. It's more convenient because it shows differences nicely, it's faster on MinGW because we have a special implementation there based only on shell-internal commands, it's simpler as it allows us to avoid stripping out unnecessary entries from the checksum file using grep(1), and it's more consistent with the rest of the test suite. We already compare changed files with their expected new contents using diff(1), so we don't need to check with "test_must_fail test_cmp" if they differ from their original state. A later patch could convert the direct diff(1) calls to test_cmp as well. With all sum(1) calls gone, remove the MinGW-specific implementation from test-lib.sh as well.
