2013-09-09Merge branch 'jc/push-cas'Libravatar Junio C Hamano3-2/+208
Allow a safer "rewind of the remote tip" push than blind "--force", by requiring that the overwritten remote ref to be unchanged since the new history to replace it was prepared. The machinery is more or less ready. The "--force" option is again the big red button to override any safety, thanks to J6t's sanity (the original round allowed --lockref to defeat --force). The logic to choose the default implemented here is fragile (e.g. "git fetch" after seeing a failure will update the remote-tracking branch and will make the next "push" pass, defeating the safety pretty easily). It is suitable only for the simplest workflows, and it may hurt users more than it helps them. * jc/push-cas: push: teach --force-with-lease to smart-http transport send-pack: fix parsing of --force-with-lease option t5540/5541: smart-http does not support "--force-with-lease" t5533: test "push --force-with-lease" push --force-with-lease: tie it all together push --force-with-lease: implement logic to populate old_sha1_expect[] remote.c: add command line option parser for "--force-with-lease" builtin/push.c: use OPT_BOOL, not OPT_BOOLEAN cache.h: move remote/connect API out of it

Allow fetch.prune and remote.*.prune configuration variables to be set, and "git fetch" to behave as if "--prune" is given. "git fetch" that honors remote.*.prune is fine, but I wonder if we should somehow make "git push" aware of it as well.

2013-09-09git-config: always treat --int as 64-bit internallyLibravatar Jeff King1-0/+7
When you run "git config --int", the maximum size of integer you get depends on how git was compiled, and what it considers to be an "int". This is almost useful, because your scripts calling "git config" will behave similarly to git internally. But relying on this is dubious; you have to actually know how git treats each value internally (e.g., int versus unsigned long), which is not documented and is subject to change. And even if you know it is "unsigned long", we do not have a git-config option to match that behavior. Furthermore, you may simply be asking git to store a value on your behalf (e.g., configuration for a hook). In that case, the relevant range check has nothing at all to do with git, but rather with whatever scripting tools you are using (and git has no way of knowing what the appropriate range is there). Not only is the range check useless, but it is actively harmful, as there is no way at all for scripts to look at config variables with large values. For instance, one cannot reliably get the value of pack.packSizeLimit via git-config. On an LP64 system, git happily uses a 64-bit "unsigned long" internally to represent the value, but the script cannot read any value over 2G. Ideally, the "--int" option would simply represent an arbitrarily large integer. For practical purposes, however, a 64-bit integer is large enough, and is much easier to implement (and if somebody overflows it, we will still notice the problem, and not simply return garbage).

2013-09-09config: make numeric parsing errors more clearLibravatar Jeff King2-4/+4
If we try to parse an integer config argument and get a number outside of the representable range, we die with the cryptic message: "bad config value for '%s'". We can improve two things: 1. Show the value that produced the error (e.g., bad config value '3g' for 'foo.bar'). 2. Mention the reason the value was rejected (e.g., "invalid unit" versus "out of range"). A few tests need to be updated with the new output, but that should not be representative of real-world breakage, as scripts should not be depending on the exact text of our stderr output, which is subject to i18n anyway.

2013-09-04pull: allow pull to preserve merges when rebasingLibravatar Stephen Haberman1-0/+89
If a user is working on master, and has merged in their feature branch, but now has to "git pull" because master moved, with pull.rebase their feature branch will be flattened into master. This is because "git pull" currently does not know about rebase's preserve merges flag, which would avoid this behavior, as it would instead replay just the merge commit of the feature branch onto the new master, and not replay each individual commit in the feature branch. Add a --rebase=preserve option, which will pass along --preserve-merges to rebase. Also add 'preserve' to the allowed values for the pull.rebase config setting.

2013-08-28mailmap: handle mailmap blobs without trailing newlinesLibravatar Jeff King1-1/+15
The read_mailmap_buf function reads each line of the mailmap using strchrnul, like: const char *end = strchrnul(buf, '\n'); unsigned long linelen = end - buf + 1; But that's off-by-one when we actually hit the NUL byte; our line does not have a terminator, and so is only "end - buf" bytes long. As a result, when we subtract the linelen from the total len, we end up with (unsigned long)-1 bytes left in the buffer, and we start reading random junk from memory. We could fix it with: unsigned long linelen = end - buf + !!*end; but let's take a step back for a moment. It's questionable in the first place for a function that takes a buffer and length to be using strchrnul. But it works because we only have one caller (and are only likely to ever have this one), which is handing us data from read_sha1_file. Which means that it's always NUL-terminated. Instead of tightening the assumptions to make the buffer/length pair work for a caller that doesn't actually exist, let's let loosen the assumptions to what the real caller has: a modifiable, NUL-terminated string. This makes the code simpler and shorter (because we don't have to correlate strchrnul with the length calculation), correct (because the code with the off-by-one just goes away), and more efficient (we can drop the extra allocation we needed to create NUL-terminated strings for each line, and just terminate in place).

As its very first action, t3404 installs (via set_fake_editor) a specialized $EDITOR which simplifies automated 'rebase -i' testing. Many tests rely upon this setting, thus tests which need a different editor must take extra care upon completion to restore $EDITOR in order to avoid breaking following tests. This places extra burden upon such tests and requires that they undesirably have extra knowledge about surrounding tests.

2013-08-25fetch-pack: do not remove .git/shallow file when --depth is not specifiedLibravatar Nguyễn Thái Ngọc Duy1-0/+16
fetch_pack() can remove .git/shallow file when a shallow repository becomes a full one again. This behavior is triggered incorrectly when tags are also fetched because fetch_pack() will be called twice. At the first fetch_pack() call: - shallow_lock is set up - alternate_shallow_file points to shallow_lock.filename, which is "shallow.lock" - commit_lock_file is called, which sets shallow_lock.filename to "". alternate_shallow_file also becomes "" because it points to the same memory. At the second call, setup_alternate_shallow() is not called and alternate_shallow_file remains "". It's mistaken as unshallow case and .git/shallow is removed. The end result is a broken repository. Fix this by always initializing alternate_shallow_file when fetch_pack() is called. As an extra measure, check if args->depth > 0 before commit/rollback shallow file.

2013-08-20xread, xwrite: limit size of IO to 8MBLibravatar Steffen Prohaska1-0/+14
Checking out 2GB or more through an external filter (see test) fails on Mac OS X 10.8.4 (12E55) for a 64-bit executable with: error: read from external filter cat failed error: cannot feed the input to external filter cat error: cat died of signal 13 error: external filter cat failed 141 error: external filter cat failed The reason is that read() immediately returns with EINVAL when asked to read more than 2GB. According to POSIX [1], if the value of nbyte passed to read() is greater than SSIZE_MAX, the result is implementation-defined. The write function has the same restriction [2]. Since OS X still supports running 32-bit executables, the 32-bit limit (SSIZE_MAX = INT_MAX = 2GB - 1) seems to be also imposed on 64-bit executables under certain conditions. For write, the problem has been addressed earlier [6c642a]. Address the problem for read() and write() differently, by limiting size of IO chunks unconditionally on all platforms in xread() and xwrite(). Large chunks only cause problems, like causing latencies when killing the process, even if OS X was not buggy. Doing IO in reasonably sized smaller chunks should have no negative impact on performance. The compat wrapper clipped_write() introduced earlier [6c642a] is not needed anymore. It will be reverted in a separate commit. The new test catches read and write problems. Note that 'git add' exits with 0 even if it prints filtering errors to stderr. The test, therefore, checks stderr. 'git add' should probably be changed (sometime in another commit) to exit with nonzero if filtering fails. The test could then be changed to use test_must_fail.

Newlines in the path to a git repository were not an issue for the git-specific bash prompt before commit efaa0c1532 (bash prompt: combine 'git rev-parse' executions in the main code path, 2013-06-17), because the path returned by 'git rev-parse --git-dir' was directly stored in a variable, and this variable was later always accessed inside double quotes. Newlines are not an issue after commit efaa0c1532 either, but it's more subtle. Since efaa0c1532 we use the following single 'git rev-parse' execution to query various info about the repository: git rev-parse --git-dir --is-inside-git-dir \ --is-bare-repository --is-inside-work-tree The results to these queries are separated by a newline character in the output, e.g.: /home/szeder/src/git/.git false false true A newline in the path to the git repository could potentially break the parsing of these results and ultimately the bash prompt, unless the parsing is done right. Commit efaa0c1532 got it right, as I consciously started parsing 'git rev-parse's output from the end, where each record is a single line containing either 'true' or 'false' or, after e3e0b9378b (bash prompt: combine 'git rev-parse' for detached head, 2013-06-24), the abbreviated commit object name, and all what remains at the beginning is the path to the git repository, no matter how many lines it is. This subtlety really warrants its own test, especially since I didn't explain it in the log message or in an in-code comment back then, so add a test to excercise the prompt with newline characters in the path to the repository. Guard this test with the FUNNYNAMES prerequisite, because not all filesystems support newlines in filenames. Note that 'git rev-parse --git-dir' prints '.git' or '.' when at the top of the worktree or the repository, respectively, and only prints the full path to the repository when in a subdirectory, hence the need for changing into a subdir in the test.

2013-08-15t3010: update to demonstrate "ls-files -k" optimization pitfallsLibravatar Junio C Hamano1-3/+9
An earlier draft of the previous step used cache_name_exists() to check the directory we were looking at, which missed the second case described in its log message. Demonstrate why it is not sufficient. Signed-off-by: Junio C Hamano <gitster@pobox.com>
2013-08-14Revert "Add new @ shortcut for HEAD"Libravatar Junio C Hamano1-2/+0
This reverts commit cdfd94837b27c220f70f032b596ea993d195488f, as it does not just apply to "@" (and forms with modifiers like @{u} applied to it), but also affects e.g. "refs/heads/@/foo", which it shouldn't. The basic idea of giving a short-hand might be good, and the topic can be retried later, but let's revert to avoid affecting existing use cases for now for the upcoming release.
2013-08-14Revert "git stash: avoid data loss when "git stash save" kills a directory"Libravatar Junio C Hamano1-18/+0
This reverts commit a73653130edd6a8977106d45a8092c09040f9132, as it has been reported that "ls-files --killed" is too time-consuming in a deep directory with too many untracked crufts (e.g. $HOME/.git tracking only a few files). We'd need to revisit it later but "ls-files --killed" needs to be optimized before it happens.
2013-08-13push: respect --no-thinLibravatar Nguyễn Thái Ngọc Duy1-0/+17
- From the beginning of push.c in 755225d, 2006-04-29, "thin" option was enabled by default but could be turned off with --no-thin. - Then Shawn changed the default to 0 in favor of saving server resources in a4503a1, 2007-09-09. --no-thin worked great. - One day later, in 9b28851 Daniel extracted some code from push.c to create transport.c. He (probably accidentally) flipped the default value from 0 to 1 in transport_get(). From then on --no-thin is effectively no-op because git-push still expects the default value to be false and only calls transport_set_option() when "thin" variable in push.c is true (which is unnecessary). Correct the code to respect --no-thin by calling transport_set_option() in both cases. receive-pack learns about --reject-thin-pack-for-testing option, which only is for testing purposes, hence no document update.

2013-08-09t/t7407: fix two typos in submodule testsLibravatar Phil Hord1-1/+1
In t/t7407-submodule-foreach.sh there is a typo in one of the path names given for a test step. The correct path is nested1/nested2/.git, but nested1/nested1/nested2/.git is given instead. The typo is hidden because this line also accidentally omits the && chain operator. The omitted chain also means the return values of all the previous commands in this test are also being ignored. Fix the path and add the chain operator so the entire test sequence can be properly validated. Signed-off-by: Phil Hord <hordp@cisco.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
