* Merge branch 'jk/config-warn-on-inaccessible-paths'Junio C Hamano2012-09-171-1/+1
|\ | | | | | | | | | | | | | | | | | | The attribute system may be asked for a path that itself or its leading directories no longer exists in the working tree. Failure to open per-directory .gitattributes with error status other than ENOENT and ENOTDIR are diagnosed. * jk/config-warn-on-inaccessible-paths: attr: failure to open a .gitattributes file is OK with ENOTDIR
| * attr: failure to open a .gitattributes file is OK with ENOTDIRJunio C Hamano2012-09-131-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Often we consult an in-tree .gitattributes file that exists per directory. Majority of directories do not usually have such a file, and it is perfectly fine if we cannot open it because there is no such file, but we do want to know when there is an I/O or permission error. Earlier, we made the codepath warn when we fail to open it for reasons other than ENOENT for that reason. We however sometimes have to attempt to open the .gitattributes file from a directory that does not exist in the commit that is currently checked out. "git pack-objects" wants to know if a path is marked with "-delta" attributes, and "git archive" wants to know about export-ignore and export-subst attributes. Both commands may and do need to ask the attributes system about paths in an arbitrary commit. "git diff", after removing an entire directory, may want to know textconv on paths that used to be in that directory. Make sure we also ignore a failure to open per-directory attributes file due to ENOTDIR. Signed-off-by: Junio C Hamano <gitster@pobox.com>
* | Merge branch 'jc/ll-merge-binary-ours'Junio C Hamano2012-09-141-1/+1
|\ \ | |/ |/| | | | | | | | | | | | | | | | | | | "git merge -Xtheirs" did not help content-level merge of binary files; it should just take their version. Also "*.jpg binary" in the attributes did not imply they should use the binary ll-merge driver. * jc/ll-merge-binary-ours: ll-merge: warn about inability to merge binary files only when we can't attr: "binary" attribute should choose built-in "binary" merge driver merge: teach -Xours/-Xtheirs to binary ll-merge driver

| | | | | | | | | | | | | | | | | | | | | | The built-in "binary" attribute macro expands to "-diff -text", so that textual diff is not produced, and the contents will not go through any CR/LF conversion ever. During a merge, it should also choose the "binary" low-level merge driver, but it didn't. Make it expand to "-diff -merge -text". Signed-off-by: Junio C Hamano <gitster@pobox.com>
* | warn_on_inaccessible(): a helper to warn on inaccessible pathsJunio C Hamano2012-08-211-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The previous series introduced warnings to multiple places, but it could become tiring to see the warning on the same path over and over again during a single run of Git. Making just one function responsible for issuing this warning, we could later choose to keep track of which paths we issued a warning (it would involve a hash table of paths after running them through real_path() or something) in order to reduce noise. Right now we do not know if the noise reduction is necessary, but it still would be a good code reduction/sharing anyway. Signed-off-by: Junio C Hamano <gitster@pobox.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If we don't have a core.attributesfile configured, we fall back to checking XDG config, which is usually $HOME/.config/git/attributes. However, if $HOME is unset, then home_config_paths will return NULL, and we end up calling fopen(NULL). Depending on your system, this may or may not cause the accompanying test to fail (e.g., on Linux and glibc, the address will go straight to open, which will return EFAULT). However, valgrind will reliably notice the error. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>

| * attr: drop misguided defensive codingJeff King2012-01-101-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In prepare_attr_stack, we pop the old elements of the stack (which were left from a previous lookup and may or may not be useful to us). Our loop to do so checks that we never reach the top of the stack. However, the code immediately afterwards will segfault if we did actually reach the top of the stack. Fortunately, this is not an actual bug, since we will never pop all of the stack elements (we will always keep the root gitattributes, as well as the builtin ones). So the extra check in the loop condition simply clutters the code and makes the intent less clear. Let's get rid of it.

| * attr: don't confuse prefixes with leading directoriesJeff King2012-01-101-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When we prepare the attribute stack for a lookup on a path, we start with the cached stack from the previous lookup (because it is common to do several lookups in the same directory hierarchy). So the first thing we must do in preparing the stack is to pop any entries that point to directories we are no longer interested in. For example, if our stack contains gitattributes for: foo/bar/baz foo/bar foo but we want to do a lookup in "foo/bar/bleep", then we want to pop the top element, but retain the others. To do this we walk down the stack from the top, popping elements that do not match our lookup directory. However, the test do this simply checked strncmp, meaning we would mistake "foo/bar/baz" as a leading directory of "foo/bar/baz_plus". We must also check that the character after our match is '/', meaning we matched the whole path component. There are two special cases to consider: 1. The top of our attr stack has the empty path. So we must not check for '/', but rather special-case the empty path, which always matches. 2. Typically when matching paths in this way, you would also need to check for a full string match (i.e., the character after is '\0'). We don't need to do so in this case, though, because our path string is actually just the directory component of the path to a file (i.e., we know that it terminates with "/", because the filename comes after that).

* | attr.c: respect core.ignorecase when matching attribute patternsBrandon Casey2011-10-111-2/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When core.ignorecase is true, the file globs configured in the .gitattributes file should be matched case-insensitively against the paths in the working directory. Let's do so. Plus, add some tests. The last set of tests is performed only on a case-insensitive filesystem. Those tests make sure that git handles the case where the .gitignore file resides in a subdirectory and the user supplies a path that does not match the case in the filesystem. In that case^H^H^H^Hsituation, part of the path supplied by the user is effectively interpreted case-insensitively, and part of it is dependent on the setting of core.ignorecase. git will currently only match the portion of the path below the directory holding the .gitignore file according to the setting of core.ignorecase. This is also partly future-proofing. Currently, git builds the attr stack based on the path supplied by the user, so we don't have to do anything special (like use strcmp_icase) to handle the parts of that path that don't match the filesystem with respect to case. If git instead built the attr stack by scanning the repository, then the paths in the origin field would not necessarily match the paths supplied by the user. If someone makes a change like that in the future, these tests will notice. Signed-off-by: Brandon Casey <drafnel@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
* | attr: read core.attributesfile from git_default_core_configJunio C Hamano2011-10-061-13/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This code calls git_config from a helper function to parse the config entry it is interested in. Calling git_config in this way may cause a problem if the helper function can be called after a previous call to git_config by another function since the second call to git_config may reset some variable to the value in the config file which was previously overridden. The above is not a problem in this case since the function passed to git_config only parses one config entry and the variable it sets is not assigned outside of the parsing function. But a programmer who desires all of the standard config options to be parsed may be tempted to modify git_attr_config() so that it falls back to git_default_config() and then it _would_ be vulnerable to the above described behavior. So, move the call to git_config up into the top-level cmd_* function and move the responsibility for parsing core.attributesfile into the main config file parser. Which is only the logical thing to do ;-) Signed-off-by: Brandon Casey <drafnel@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
* | cleanup: use internal memory allocation wrapper functions everywhereBrandon Casey2011-10-061-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The "x"-prefixed versions of strdup, malloc, etc. will check whether the allocation was successful and terminate the process otherwise. A few uses of malloc were left alone since they already implemented a graceful path of failure or were in a quasi external library like xdiff. Additionally, the call to malloc in compat/win32/syslog.c was not modified since the syslog() implemented there is a die handler and a call to the x-wrappers within a die handler could result in recursion should memory allocation fail. This will have to be addressed separately. Signed-off-by: Brandon Casey <drafnel@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
* | attr.c: avoid inappropriate access to strbuf "buf" memberBrandon Casey2011-10-061-13/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This code sequence performs a strcpy into the buf member of a strbuf struct. The strcpy may move the position of the terminating nul of the string and effectively change the length of string so that it does not match the len member of the strbuf struct. Currently, this sequence works since the strbuf was given a hint when it was initialized to allocate enough space to accomodate the string that will be strcpy'ed, but this is an implementation detail of strbufs, not a guarantee. So, lets rework this sequence so that the strbuf is only manipulated by strbuf functions, and direct modification of its "buf" member is not necessary.

* Fix big left-shifts of unsigned charLinus Torvalds2009-06-181-2/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Shifting 'unsigned char' or 'unsigned short' left can result in sign extension errors, since the C integer promotion rules means that the unsigned char/short will get implicitly promoted to a signed 'int' due to the shift (or due to other operations). This normally doesn't matter, but if you shift things up sufficiently, it will now set the sign bit in 'int', and a subsequent cast to a bigger type (eg 'long' or 'unsigned long') will now sign-extend the value despite the original expression being unsigned. One example of this would be something like unsigned long size; unsigned char c; size += c << 24; where despite all the variables being unsigned, 'c << 24' ends up being a signed entity, and will get sign-extended when then doing the addition in an 'unsigned long' type. Since git uses 'unsigned char' pointers extensively, we actually have this bug in a couple of places. I may have missed some, but this is the result of looking at git grep '[^0-9 ][ ]*<<[ ][a-z]' -- '*.c' '*.h' git grep '<<[ ]*24' which catches at least the common byte cases (shifting variables by a variable amount, and shifting by 24 bits). I also grepped for just 'unsigned char' variables in general, and converted the ones that most obviously ended up getting implicitly cast immediately anyway (eg hash_name(), encode_85()). In addition to just avoiding 'unsigned char', this patch also tries to use a common idiom for the delta header size thing. We had three different variations on it: "& 0x7fUL" in one place (getting the sign extension right), and "& ~0x80" and "& 0x7f" in two other places (not getting it right). Apart from making them all just avoid using "unsigned char" at all, I also unified them to then use a simple "& 0x7f". I considered making a sparse extension which warns about doing implicit casts from unsigned types to signed types, but it gets rather complex very quickly, so this is just a hack.

* Read attributes from the index that is being checked outJunio C Hamano2009-03-131-18/+55
| | | | | | | | | | | | | | | | | | Traditionally we used .gitattributes file from the work tree if exists, and otherwise read from the index as a fallback. When switching to a branch that has an updated .gitattributes file, and entries in it give different attributes to other paths being checked out, we should instead read from the .gitattributes in the index. This breaks a use case of fixing incorrect entries in the .gitattributes in the work tree (without adding it to the index) and checking other paths out, though. $ edit .gitattributes ;# mark foo.dat as binary $ rm foo.dat $ git checkout foo.dat Signed-off-by: Junio C Hamano <gitster@pobox.com>
