* Merge branch 'tb/core-eol-fix' into maintJunio C Hamano2016-06-06
|\ | | | | | | | | | | | | | | | | | | A couple of bugs around core.autocrlf have been fixed. * tb/core-eol-fix: convert.c: ident + core.autocrlf didn't work t0027: test cases for combined attributes convert: allow core.autocrlf=input and core.eol=crlf t0027: make commit_chk_wrnNNO() reliable
| * convert: allow core.autocrlf=input and core.eol=crlfTorsten Bögershausen2016-04-25
| | | | | | | | | | | | | | | | | | | | | | | | Even though the configuration parser errors out when core.autocrlf is set to 'input' when core.eol is set to 'crlf', there is no need to do so, because the core.autocrlf setting trumps core.eol. Allow all combinations of core.crlf and core.eol and document that core.autocrlf overrides core.eol.

| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On Unix (and Linux), files and directories whose names start with a dot are usually not shown by default. This convention is used by Git: the .git/ directory should be left alone by regular users, and only accessed through Git itself. On Windows, no such convention exists. Instead, there is an explicit flag to mark files or directories as hidden. In the early days, Git for Windows did not mark the .git/ directory (or for that matter, any file or directory whose name starts with a dot) hidden. This lead to quite a bit of confusion, and even loss of data. Consequently, Git for Windows introduced the core.hideDotFiles setting, with three possible values: true, false, and dotGitOnly, defaulting to marking only the .git/ directory as hidden. The rationale: users do not need to access .git/ directly, and indeed (as was demonstrated) should not really see that directory, either. However, not all dot files should be hidden by default, as e.g. Eclipse does not show them (and the user would therefore be unable to see, say, a .gitattributes file). In over five years since the last attempt to bring this patch into core Git, a slightly buggy version of this patch has served Git for Windows' users well: no single report indicated problems with the hidden .git/ directory, and the stream of problems caused by the previously non-hidden .git/ directory simply stopped. The bugs have been fixed during the process of getting this patch upstream. Note that there is a funny quirk we have to pay attention to when creating hidden files: we use Win32's _wopen() function which transmogrifies its arguments and hands off to Win32's CreateFile() function. That latter function errors out with ERROR_ACCESS_DENIED (the equivalent of EACCES) when the equivalent of the O_CREAT flag was passed and the file attributes (including the hidden flag) do not match an existing file's. And _wopen() accepts no parameter that would be transmogrified into said hidden flag. Therefore, we simply try again without O_CREAT. A slightly different method is required for our fopen()/freopen() function as we cannot even *remove* the implicit O_CREAT flag. Therefore, we briefly mark existing files as unhidden when opening them via fopen()/freopen(). The ERROR_ACCESS_DENIED error can also be triggered by opening a file that is marked as a system file (which is unlikely to be tracked in Git), and by trying to create a file that has *just* been deleted and is awaiting the last open handles to be released (which would be handled better by the "Try again?" logic, a story for a different patch series, though). In both cases, it does not matter much if we try again without the O_CREAT flag, read: it does not hurt, either.

As some code may rely on the actual return values for `git_config_set` we still require the ability to invoke these functions without aborting.

These wrappers are temporary only to ease the transition to let `git_config_set` die by default. They will be removed later on when `git_config_set` itself has been replaced by `git_config_set_gently`.

| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We frequently allocate strings as xmalloc(len + 1), where the extra 1 is for the NUL terminator. This can be done more simply with xmallocz, which also checks for integer overflow. There's no case where switching xmalloc(n+1) to xmallocz(n) is wrong; the result is the same length, and malloc made no guarantees about what was in the buffer anyway. But in some cases, we can stop manually placing NUL at the end of the allocated buffer. But that's only safe if it's clear that the contents will always fill the buffer. In each case where this patch does so, I manually examined the control flow, and I tried to err on the side of caution.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | To correctly perform its testing function, test-dump-untracked-cache should not change the state of the untracked cache in the index. As a previous patch makes read_index_from() change the state of the untracked cache and as test-dump-untracked-cache indirectly calls this function, we need a mechanism to prevent read_index_from() from changing the untracked cache state when it's called from test-dump-untracked-cache.

|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When we know that mtime on directory as given by the environment is usable for the purpose of untracked cache, we may want the untracked cache to be always used without any mtime test or kernel name check being performed. Also when we know that mtime is not usable for the purpose of untracked cache, for example because the repo is shared over a network file system, we may want the untracked-cache to be automatically removed from the index. Allow the user to express such preference by setting the 'core.untrackedCache' configuration variable, which can take 'keep', 'false', or 'true' and default to 'keep'. When read_index_from() is called, it now adds or removes the untracked cache in the index to respect the value of this variable. So it does nothing if the value is `keep` or if the variable is unset; it adds the untracked cache if the value is `true`; and it removes the cache if the value is `false`. `git update-index --[no-|force-]untracked-cache` still adds the untracked cache to, or removes it, from the index, but this shows a warning if it goes against the value of core.untrackedCache, because the next time the index is read the untracked cache will be added or removed if the configuration is set to do so. Also `--untracked-cache` used to check that the underlying operating system and file system change `st_mtime` field of a directory if files are added or deleted in that directory. But because those tests take a long time, `--untracked-cache` no longer performs them. Instead, there is now `--test-untracked-cache` to perform the tests. This change makes `--untracked-cache` the same as `--force-untracked-cache`. This last change is backward incompatible and should be mentioned in the release notes.

* Make error message after failing commit_lock_file() less confusingSZEDER Gábor2015-12-01
| | | | | | | | | | | | | | | | | | | | | | | | | | | | The error message after a failing commit_lock_file() call sometimes looks like this, causing confusion: $ git remote add remote git@server.com/repo.git error: could not commit config file .git/config # Huh?! # I didn't want to commit anything, especially not my config file! While in the narrow context of the lockfile module using the verb 'commit' in the error message makes perfect sense, in the broader context of git the word 'commit' already has a very specific meaning, hence the confusion. Reword these error messages to say "could not write" instead of "could not commit". While at it, include strerror in the error messages after writing the config file or the credential store fails to provide some information about the cause of the failure, and update the style of the error message after writing the reflog fails to match surrounding error messages (i.e. no '' around the pathname and no () around the error description).

These config schemes are mis-designed, as the command names can be anything, but the config syntax has some restrictions. For example: $ git foo_bar error: invalid key: pager.foo_bar error: invalid key: alias.foo_bar git: 'foo_bar' is not a git command. See 'git --help'. You cannot name an alias with an underscore. And if you have an external command with one, you cannot configure its pager. In the long run, we may develop a different config scheme for these features. But in the near term (and because we'll need to support the existing scheme indefinitely), we should at least squelch the error messages shown above. These errors come from git_config_parse_key. Ideally we would pass a "quiet" flag to the config machinery, but there are many layers between the pager code and the key parsing. Passing a flag through all of those would be an invasive change. Instead, let's provide a config function to report on whether a key is syntactically valid, and have the pager and alias code skip lookup for bogus keys. We can build this easily around the existing git_config_parse_key, with two minor modifications: 1. We now handle a NULL store_key, to validate but not write out the normalized key. 2. We accept a "quiet" flag to avoid writing to stderr. This doesn't need to be a full-blown public "flags" field, because we can make the existing implementation a static helper function, keeping the mess contained inside config.c.

This has two downsides: 1. The error message is not very helpful, as it lacks any context about the file we are mapping: $ mkdir foo $ git config --file=foo some.key value fatal: Out of memory? mmap failed: No such device 2. We normally do not die in this code path; instead, we'd rather report the error and return an appropriate exit status (which is part of the public interface documented in git-config.1). This patch introduces a "gentle" form of xmmap which lets us produce our own error message. We do not want to use mmap directly, because we would like to use the other compatibility elements of xmmap (e.g., handling 0-length maps portably). The end result is: $ git.compile config --file=foo some.key value error: unable to mmap 'foo': No such device $ echo $? 3 Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>

This incurs significant locking overhead, even though we know that only one thread can possibly access the handle. We can speed this up by taking the lock ourselves, and then using getc_unlocked to read each character. On a silly pathological case: perl -le ' print "[core]"; print "key$_ = value$_" for (1..1000000) ' >input git config -f input core.key1 this dropped the time to run git-config from: real 0m0.263s user 0m0.260s sys 0m0.000s to: real 0m0.159s user 0m0.152s sys 0m0.004s for a savings of 39%. Most config files are not this big, but the savings should be proportional to the size of the file (i.e., we always save 39%, just of a much smaller number).

In particular, we only rewind the position by one character, but do _not_ actually put the character from the caller into position. It turns out that this does not matter, because we only ever push back the character we just read. In other words, such an assignment would be a noop. But because the function is called ungetc, and because it takes a character parameter, it is a mistake waiting to happen. Actually assigning the character into the buffer would be ideal, but our pointer is actually a "const" copy of the buffer. We do not know who the real owner of the buffer is in this code, and would not want to munge their contents. Instead, we can simply add an assertion that matches what the current caller does, and will let us know if new callers are added that violate the contract.
