6be5ac23	2019-07-11T15:30:51	checkout: postpone creation of symlinks to the end On most platforms it's fine to create symlinks to nonexisting files. Not so on Windows, where the type of a symlink (file or directory) needs to be set at creation time. So depending on whether the target file exists or not, we may end up with different symlink types. This creates a problem when performing checkouts, where we simply iterate over all blobs that need to be updated without treating symlinks any special. If the target file of the symlink is going to be checked out after the symlink itself, then the symlink will be created as directory symlink and not as file symlink. Fix the issue by iterating over blobs twice: once to perform postponed deletions and updates to non-symlink blobs, and once to perform updates to symlink blobs.
658022c4	2019-07-18T13:53:41	configuration: cvar -> configmap `cvar` is an unhelpful name. Refactor its usage to `configmap` for more clarity.
0b5ba0d7	2019-06-06T16:36:23	Rename opt init functions to `options_init` In libgit2 nomenclature, when we need to verb a direct object, we name a function `git_directobject_verb`. Thus, if we need to init an options structure named `git_foo_options`, then the name of the function that does that should be `git_foo_options_init`. The previous names of `git_foo_init_options` is close - it _sounds_ as if it's initializing the options of a `foo`, but in fact `git_foo_options` is its own noun that should be respected. Deprecate the old names; they'll now call directly to the new ones.
351eeff3	2019-01-23T10:42:46	maps: use uniform lifecycle management functions Currently, the lifecycle functions for maps (allocation, deallocation, resize) are not named in a uniform way and do not have a uniform function signature. Rename the functions to fix that, and stick to libgit2's naming scheme of saying `git_foo_new`. This results in the following new interface for allocation: - `int git_<t>map_new(git_<t>map *out)` to allocate a new map, returning an error code if we ran out of memory - `void git_<t>map_free(git_<t>map map)` to free a map - `void git_<t>map_clear(git<t>map *map)` to remove all entries from a map This commit also fixes all existing callers.

5e26391a	2018-06-18T18:28:08	checkout: FORCE doesn't halt on dirty index If the index is dirty, allow `GIT_CHECKOUT_FORCE` to obliterate unsaved changes. This is in keeping with its name and description.
b242cdbf	2017-11-17T00:19:07	index: commit the changes to the index properly Now that the index has a "dirty" state, where it has changes that have not yet been committed or rolled back, our tests need to be adapted to actually commit or rollback the changes instead of assuming that the index can be operated on in its indeterminate state.
88b30f51	2017-11-12T20:50:00	checkout: always set the index in checkout data Always set the `index` in the `checkout_data`, even in the case that we are not reloading the index. Other functionality in checkout examines the index (for example: determining whether the workdir is modified) and we need it even in the (uncommon) case that we are not reloading.

a7168b47	2018-05-22T16:13:47	path: reject .gitmodules as a symlink Any part of the library which asks the question can pass in the mode to have it checked against `.gitmodules` being a symlink. This is particularly relevant for adding entries to the index from the worktree and for checking out files.
c214ba19	2018-02-20T00:35:27	checkout: respect core.filemode when comparing filemodes Fixes #4504
d7fea1e1	2018-02-18T16:10:33	checkout: take mode into account when comparing index to baseline When checking out a file, we determine whether the baseline (what we expect to be in the working directory) actually matches the contents of the working directory. This is safe behavior to prevent us from overwriting changes in the working directory. We look at the index to optimize this test: if we know that the index matches the working directory, then we can simply look at the index data compared to the baseline. We have historically compared the baseline to the index entry by oid. However, we must also compare the mode of the two items to ensure that they are identical. Otherwise, we will refuse to update the working directory for a mode change.
2a3e0635	2017-12-04T16:56:07	Do not attempt to check out submodule as blob when merging a submodule modify/deltete conflict
128c5ca9	2017-10-07T12:23:33	checkout: do not test file mode on Windows On Windows, we do not support file mode changes, so do not test for type changes between the disk and tree being checked out. We could have false positives since the on-disk file can only have an (effective) mode of 0100644 since NTFS does not support executable files. If the tree being checked out did have an executable file, we would erroneously decide that the file on disk had been changed.
752b7c79	2016-06-15T02:00:35	checkout: treat files as modified if mode differs When performing a forced checkout, treat files as modified when the workdir or the index is identical except for the mode. This ensures that force checkout will update the mode to the target. (Apply this check for regular files only, if one of the items was a file and the other was another type of item then this would be a typechange and handled independently.)
0c7f49dd	2017-06-30T13:39:01	Make sure to always include "common.h" first Next to including several files, our "common.h" header also declares various macros which are then used throughout the project. As such, we have to make sure to always include this file first in all implementation files. Otherwise, we might encounter problems or even silent behavioural differences due to macros or defines not being defined as they should be. So in fact, our header and implementation files should make sure to always include "common.h" first. This commit does so by establishing a common include pattern. Header files inside of "src" will now always include "common.h" as its first other file, separated by a newline from all the other includes to make it stand out as special. There are two cases for the implementation files. If they do have a matching header file, they will always include this one first, leading to "common.h" being transitively included as first file. If they do not have a matching header file, they instead include "common.h" as first file themselves. This fixes the outlined problems and will become our standard practice for header and source files inside of the "src/" from now on.
83989d70	2017-06-08T22:23:53	checkout: cope with untracked files in directory deletion When deleting a directory during checkout, do not simply delete the directory, since there may be untracked files. Instead, go into the iterator and examine each file. In the original code (the code with the faulty assumption), we look to see if there's an index entry beneath the directory that we want to remove. Eg, it looks to see if we have a workdir entry foo and an index entry foo/bar.txt. If this is not the case, then the working directory must have precious files in that directory. This part is okay. The part that's not okay is if there is an index entry foo/bar.txt. It just blows away the whole damned directory. That's not cool. Instead, by simply pushing the directory itself onto the stack and iterating each entry, we will deal with the files one by one - whether they're in the index (and can be force removed) or not (and are precious). The original code was a bad optimization, assuming that we didn't need to git_iterator_advance_into if there was any index entry in the folder. That's wrong - we could have optimized this iff all folder entries are in the index. Instead, we need to simply dig into the directory and analyze its entries.
77c8ee74	2017-03-20T08:59:30	checkout: fix double-free of checkout_data's mkdir_map We currently call `git_strmap_free` on `checkout_data.mkdir_map` in the `checkout_data_clear` function. The only thing protecting us from a double-free is that the `git_strmap_free` function is in fact not a function, but a macro that also sets the map to NULL. Remove the second call to `git_strmap_free` and explicitly set the map member to NULL.

cb76eed5	2017-01-14T17:41:49	Merge pull request #4054 from jfultz/jfultz/fix_GIT_CHECKOUT_DISABLE_PATHSPEC_MATCH Fix handling of GIT_CHECKOUT_DISABLE_PATHSPEC_MATCH flag.
5f959dca	2016-12-29T19:26:50	Fix handling of GIT_CHECKOUT_DISABLE_PATHSPEC_MATCH flag. git_checkout_tree() sets up its working directory iterator to respect the pathlist if GIT_CHECKOUT_DISABLE_PATHSPEC_MATCH is present, which is great. What's not so great is that this iterator is then used side-by-side with an iterator created by git_checkout_iterator(), which did not set up its pathlist appropriately (although the iterator mirrors all other iterator options). This could cause git_checkout_tree() to delete working tree files which were not specified in the pathlist when GIT_CHECKOUT_DISABLE_PATHSPEC_MATCH was used, as the unsynchronized iterators causes git_checkout_tree() to think that files have been deleted between the two trees. Oops. And added a test which fails without this fix (specifically, the final check for "testrepo/README" to still be present fails).
909d5494	2016-12-29T12:25:15	giterr_set: consistent error messages Error messages should be sentence fragments, and therefore: 1. Should not begin with a capital letter, 2. Should not conclude with punctuation, and 3. Should not end a sentence and begin a new one
90a934a5	2016-11-14T10:06:17	checkout: pass string instead of git_buf to `giterr_set`
955c99c2	2016-09-14T10:28:24	checkout: don't try to calculate oid for directories When trying to determine if we can safely overwrite an existing workdir item, we may need to calculate the oid for the workdir item to determine if its identical to the old side (and eligible for removal). We previously did this regardless of the type of entry in the workdir; if it was a directory, we would open(2) it and then try to read(2). The read(2) of a directory fails on many platforms, so we would treat it as if it were unmodified and continue to perform the checkout. On FreeBSD, you _can_ read(2) a directory, so this pattern failed. We would calculate an oid from the data read and determine that the directory was modified and would therefore generate a checkout conflict. This reliance on read(2) is silly (and was most likely accidentally giving us the behavior we wanted), we should be explicit about the directory test.
88cfe614	2016-08-24T01:20:39	git_checkout_tree options fix According to the reference the git_checkout_tree and git_checkout_head functions should accept NULL in the opts field This was broken since the opts field was dereferenced and thus lead to a crash.

afab1fff	2016-02-16T21:02:41	checkout: handle dirty submodules correctly Don't generate conflicts when checking out a modified submodule and the submodule is dirty or modified in the workdir.
7b24c4fd	2016-05-02T15:47:54	checkout: set ignorecase=0 when config lookup fails When `git_repository__cvar` fails we may end up with a `ignorecase` value of `-1`. As we subsequently check if `ignorecase` is non-zero, we may end up reporting that data should be removed when in fact it should not. Err on the safer side and set `ignorecase = 0` when `git_repository__cvar` fails.
0a2e1032	2016-03-17T15:19:45	iterator: drop `advance_into_or_over` Now that iterators do not return `GIT_ENOTFOUND` when advancing into an empty directory, we do not need a special `advance_into_or_over` function.
0e0589fc	2016-03-10T00:04:26	iterator: combine fs+workdir iterators more completely Drop some of the layers of indirection between the workdir and the filesystem iterators. This makes the code a little bit easier to follow, and reduces the number of unnecessary allocations a bit as well. (Prior to this, when we filter entries, we would allocate them, filter them and then free them; now we do the filtering before allocation.) Also, rename `git_iterator_advance_over_with_status` to just `git_iterator_advance_over`. Mostly because it's a fucking long-ass function name otherwise.
702b23d7	2016-03-11T11:27:58	checkout: provide internal func to compute target path Many code paths in checkout need the final, full on-disk path of the file they're writing. (No surprise). However, they all munge the `data->path` buffer themselves to get there. Provide a nice helper method for them. Plus, drop the use `git_iterator_current_workdir_path` which does the same thing but different. Checkout is the only caller of this silly function, which lets us remove it.
684b35c4	2016-02-25T15:11:14	iterator: disambiguate reset and reset_range Disambiguate the reset and reset_range functions. Now reset_range with a NULL path will clear the start or end; reset will leave the existing start and end unchanged.
594a5d12	2016-02-18T12:28:06	Merge pull request #3619 from ethomson/win32_forbidden win32: allow us to read indexes with forbidden paths on win32
318b825e	2016-02-16T17:11:46	index: allow read of index w/ illegal entries Allow `git_index_read` to handle reading existing indexes with illegal entries. Allow the low-level `git_index_add` to add properly formed `git_index_entry`s even if they contain paths that would be illegal for the current filesystem (eg, `AUX`). Continue to disallow `git_index_add_bypath` from adding entries that are illegal universally illegal (eg, `.git`, `foo/../bar`).

25e84f95	2015-11-23T15:49:54	checkout: only consider nsecs when built that way When examining the working directory and determining whether it's up-to-date, only consider the nanoseconds in the index entry when built with `GIT_USE_NSEC`. This prevents us from believing that the working directory is always dirty when the index was originally written with a git client that uinderstands nsecs (like git 2.x).

ac2fba0e	2015-09-16T15:07:27	git_futils_mkdir_*: make a relative-to-base mkdir Untangle git_futils_mkdir from git_futils_mkdir_ext - the latter assumes that we own everything beneath the base, as if it were being called with a base of the repository or working directory, and is tailored towards checkout and ensuring that there is no bogosity beneath the base that must be cleaned up. This is (at best) slow and (at worst) unsafe in the larger context of a filesystem where we do not own things and cannot do things like unlink symlinks that are in our way.
eea7c850	2015-09-16T05:44:27	checkout: overwrite files with differing modes When a file exists on disk and we're checking out a file that differs in executableness, remove the old file. This allows us to recreate the new file with p_open, which will take the new mode into account and handle setting the umask properly. Remove any notion of chmod'ing existing files, since it is now handled by the aforementioned removal and was incorrect, as it did not take umask into account.

768f8be3	2015-06-30T19:00:41	Fix #3094 - improve use of portable size_t/ssize_t format specifiers. The header src/cc-compat.h defines portable format specifiers PRIuZ, PRIdZ, and PRIxZ. The original report highlighted the need to use these specifiers in examples/network/fetch.c. For this commit, I checked all C source and header files not in deps/ and transitioned to the appropriate format specifier where appropriate.
c2418f46	2015-06-25T12:48:44	Rename FALLBACK to UNSPECIFIED Fallback describes the mechanism, while unspecified explains what the user is thinking.
c6f489c9	2015-05-04T17:29:12	submodule: add an ignore option to status This lets us specify in the status call which ignore rules we want to use (optionally falling back to whatever the submodule has in its configuration). This removes one of the reasons for having `_set_ignore()` set the value in-memory. We re-use the `IGNORE_RESET` value for this as it is no longer relevant but has a similar purpose to `IGNORE_FALLBACK`. Similarly, we remove `IGNORE_DEFAULT` which does not have use outside of initializers and move that to fall back to the configuration as well.
64bbd47a	2015-05-04T17:09:21	submodule: don't let status change an existing instance As submodules are becomes more like values, we should not let a status check to update its properties. Instead of taking a submodule, have status take a repo and submodule name.
dfda2f68	2015-04-27T19:27:29	submodule: remove the per-repo cache Having this cache and giving them out goes against our multithreading guarantees and it makes it impossible to use submodules in a multi-threaded environment, as any thread can ask for a refresh which may reallocate some string in the submodule struct which we've accessed in a different one via a getter. This makes the submodules behave more like remotes, where each object is created upon request and not shared except explicitly by the user. This means that some tests won't pass yet, as they assume they can affect the submodule objects in the cache and that will affect later operations.
96dd171e	2015-06-19T08:32:26	diff: preserve original mode in the index When updating the index during a diff, preserve the original mode, which prevents us from dropping the mode to what we have interpreted as on our system (eg, what the working directory claims it to be, which may be a lie on some systems.)
892abf93	2015-06-16T17:23:12	checkout: allow workdir to contain checkout target When checking out some file 'foo' that has been modified in the working directory, allow the checkout to proceed (do not conflict) if 'foo' is identical to the target of the checkout.
885b94aa	2015-05-28T15:26:13	Rename GIT_EMERGECONFLICT to GIT_ECONFLICT We do not error on "merge conflicts"; on the contrary, merge conflicts are a normal part of merging. We only error on "checkout conflicts", where a change exists in the index or the working directory that would otherwise be overwritten by performing the checkout. This may happen during merge (after the production of the new index that we're going to checkout) but it could happen during any checkout.
73dce1f6	2015-03-16T18:57:57	checkout: allow baseline to be specified as index Allow the baseline to be specified as an index, so that users need not write their index to a tree just to checkout with that as the baseline.
4beab1f8	2015-03-31T16:29:35	checkout: break case-changes into delete/add When checking out with a case-insensitive working directory, we want to change the case of items in the working directory to reflect changes that occured in the checkout target.

3520c970	2015-03-27T15:39:28	Revert "Always checkout with case sensitive iterator" This reverts commit 40d791545abfb3cb71553a27dc64129e1a9bec28.
69f0032b	2015-04-28T12:40:20	Fix some build warnings In checkout.c and filter.c we were casting a sub struct to a parent struct which breaks the strict aliasing rules in C. However we can use .parent or .base to access the parent struct to avoid the build warnings. In remote.c the local variable error was not initialized or updated in some cases. For unintialized error a build warning will be generated. So always keep error variable up-to-date.
d3282680	2015-04-20T23:41:04	Fix index-adding functions to know when to trust filemodes. The idea...sometimes, a filemode is user-specified via an explicit git_index_entry. In this case, believe the user, always. Sometimes, it is instead built up by statting the file system. In those cases, go with the existing logic we have to determine whether the file system supports all filemodes and symlinks, and make the best guess. On file systems which have full filemode and symlink support, this commit should make no difference. On others (most notably Windows), this will fix problems things like: * git_index_add and git_index_add_frombuffer() should be believed. * As a consequence, git_checkout_tree should make the filemodes in the index match the ones in the tree. * And diffs with GIT_DIFF_UPDATE_INDEX don't write the wrong filemodes. * And merges, and probably other downstream stuff now fixed, too. This makes my previous changes to checkout.c unnecessary, so they are now reverted. Also, added a test for index_entry permissions from git_index_add and git_index_add_frombuffer, both of which failed before these changes.
6598aa7e	2015-04-16T14:10:34	Oops...need bitwise, not logical negation.
67db2bde	2015-03-10T12:02:45	Fix git_checkout_tree() to do index filemodes correctly on Windows. git_checkout_tree() has some fallback behaviors for file systems which don't have full support of filemodes. Generally works fine, but if a given file had a change of type from a 0644 to 0755 (i.e., you add executable permissions), the fallback behavior incorrectly triggers when writing hte updated index. This would cause a git_checkout_tree() command, even with the GIT_CHECKOUT_FORCE option set, to leave a dirty index on Windows. Also added checks to an existing test to catch this case.

9a97f49e	2014-12-21T15:31:03	config: borrow refcounted references This changes the get_entry() method to return a refcounted version of the config entry, which you have to free when you're done. This allows us to avoid freeing the memory in which the entry is stored on a refresh, which may happen at any time for a live config. For this reason, get_string() has been forbidden on live configs and a new function get_string_buf() has been added, which stores the string in a git_buf which the user then owns. The functions which parse the string value takea advantage of the borrowing to parse safely and then release the entry.

Instead, create an "attribute session" during checkout. Assume that attribute data read in the same checkout "session" hasn't been modified since the checkout started. (But allow subsequent checkouts to invalidate the cache.) Further, cache nonexistent git_attr_file data even when .gitattributes files are not found to prevent re-scanning for nonexistent files.

As a result, writing these paths literally (using \\?\ syntax) makes them hard to operate with from the shell, Windows Explorer or other tools. Disallow these.

62a617dc	2014-11-06T16:16:46	iterator: submodules are determined by an index or tree We cannot know from looking at .gitmodules whether a directory is a submodule or not. We need the index or tree we are comparing against to tell us. Otherwise we have to assume the entry in .gitmodules is stale or otherwise invalid. Thus we pass the index of the repository into the workdir iterator, even if we do not want to compare against it. This follows what git does, which even for `git diff <tree>`, it will consider staged submodules as such.

This adds a new flag to diff so that if the OID calculation finds that the file actually has not changed (i.e. just the modified time was altered or such), then it will refresh the stat cache in the index so that future calls to diff will not have to check the oid again.
0fc8e1f6	2014-04-28T14:34:55	Lay groundwork for updating stat cache in diff This reorganized the diff OID calculation to make it easier to correctly update the stat cache during a diff once the flags to do so are enabled. This includes marking the path of a git_index_entry as const so we can make a "fake" git_index_entry with a "const char *" path and not get warnings. I was a little surprised at how unobtrusive this change was, but I think it's probably a good thing.

checkout: postpone creation of symlinks to the end On most platforms it's fine to create symlinks to nonexisting files. Not so on Windows, where the type of a symlink (file or directory) needs to be set at creation time. So depending on whether the target file exists or not, we may end up with different symlink types. This creates a problem when performing checkouts, where we simply iterate over all blobs that need to be updated without treating symlinks any special. If the target file of the symlink is going to be checked out after the symlink itself, then the symlink will be created as directory symlink and not as file symlink. Fix the issue by iterating over blobs twice: once to perform postponed deletions and updates to non-symlink blobs, and once to perform updates to symlink blobs.

Rename opt init functions to `options_init` In libgit2 nomenclature, when we need to verb a direct object, we name a function `git_directobject_verb`. Thus, if we need to init an options structure named `git_foo_options`, then the name of the function that does that should be `git_foo_options_init`. The previous names of `git_foo_init_options` is close - it _sounds_ as if it's initializing the options of a `foo`, but in fact `git_foo_options` is its own noun that should be respected. Deprecate the old names; they'll now call directly to the new ones.

maps: use uniform lifecycle management functions Currently, the lifecycle functions for maps (allocation, deallocation, resize) are not named in a uniform way and do not have a uniform function signature. Rename the functions to fix that, and stick to libgit2's naming scheme of saying `git_foo_new`. This results in the following new interface for allocation: - `int git_<t>map_new(git_<t>map **out)` to allocate a new map, returning an error code if we ran out of memory - `void git_<t>map_free(git_<t>map *map)` to free a map - `void git_<t>map_clear(git<t>map *map)` to remove all entries from a map This commit also fixes all existing callers.

checkout: respect core.filemode when comparing filemodes Fixes #4504

d7fea1e1

2018-02-18T16:10:33

checkout: take mode into account when comparing index to baseline When checking out a file, we determine whether the baseline (what we expect to be in the working directory) actually matches the contents of the working directory. This is safe behavior to prevent us from overwriting changes in the working directory. We look at the index to optimize this test: if we know that the index matches the working directory, then we can simply look at the index data compared to the baseline. We have historically compared the baseline to the index entry by oid. However, we must also compare the mode of the two items to ensure that they are identical. Otherwise, we will refuse to update the working directory for a mode change.

checkout: do not test file mode on Windows On Windows, we do not support file mode changes, so do not test for type changes between the disk and tree being checked out. We could have false positives since the on-disk file can only have an (effective) mode of 0100644 since NTFS does not support executable files. If the tree being checked out did have an executable file, we would erroneously decide that the file on disk had been changed.

Make sure to always include "common.h" first Next to including several files, our "common.h" header also declares various macros which are then used throughout the project. As such, we have to make sure to always include this file first in all implementation files. Otherwise, we might encounter problems or even silent behavioural differences due to macros or defines not being defined as they should be. So in fact, our header and implementation files should make sure to always include "common.h" first. This commit does so by establishing a common include pattern. Header files inside of "src" will now always include "common.h" as its first other file, separated by a newline from all the other includes to make it stand out as special. There are two cases for the implementation files. If they do have a matching header file, they will always include this one first, leading to "common.h" being transitively included as first file. If they do not have a matching header file, they instead include "common.h" as first file themselves. This fixes the outlined problems and will become our standard practice for header and source files inside of the "src/" from now on.

checkout: cope with untracked files in directory deletion When deleting a directory during checkout, do not simply delete the directory, since there may be untracked files. Instead, go into the iterator and examine each file. In the original code (the code with the faulty assumption), we look to see if there's an index entry beneath the directory that we want to remove. Eg, it looks to see if we have a workdir entry foo and an index entry foo/bar.txt. If this is not the case, then the working directory must have precious files in that directory. This part is okay. The part that's not okay is if there is an index entry foo/bar.txt. It just blows away the whole damned directory. That's not cool. Instead, by simply pushing the directory itself onto the stack and iterating each entry, we will deal with the files one by one - whether they're in the index (and can be force removed) or not (and are precious). The original code was a bad optimization, assuming that we didn't need to git_iterator_advance_into if there was any index entry in the folder. That's wrong - we could have optimized this iff all folder entries are in the index. Instead, we need to simply dig into the directory and analyze its entries.

checkout: fix double-free of checkout_data's mkdir_map We currently call `git_strmap_free` on `checkout_data.mkdir_map` in the `checkout_data_clear` function. The only thing protecting us from a double-free is that the `git_strmap_free` function is in fact not a function, but a macro that also sets the map to NULL. Remove the second call to `git_strmap_free` and explicitly set the map member to NULL.

Fix handling of GIT_CHECKOUT_DISABLE_PATHSPEC_MATCH flag. git_checkout_tree() sets up its working directory iterator to respect the pathlist if GIT_CHECKOUT_DISABLE_PATHSPEC_MATCH is present, which is great. What's not so great is that this iterator is then used side-by-side with an iterator created by git_checkout_iterator(), which did not set up its pathlist appropriately (although the iterator mirrors all other iterator options). This could cause git_checkout_tree() to delete working tree files which were not specified in the pathlist when GIT_CHECKOUT_DISABLE_PATHSPEC_MATCH was used, as the unsynchronized iterators causes git_checkout_tree() to think that files have been deleted between the two trees. Oops. And added a test which fails without this fix (specifically, the final check for "testrepo/README" to still be present fails).

checkout: don't try to calculate oid for directories When trying to determine if we can safely overwrite an existing workdir item, we may need to calculate the oid for the workdir item to determine if its identical to the old side (and eligible for removal). We previously did this regardless of the type of entry in the workdir; if it was a directory, we would open(2) it and then try to read(2). The read(2) of a directory fails on many platforms, so we would treat it as if it were unmodified and continue to perform the checkout. On FreeBSD, you _can_ read(2) a directory, so this pattern failed. We would calculate an oid from the data read and determine that the directory was modified and would therefore generate a checkout conflict. This reliance on read(2) is silly (and was most likely accidentally giving us the behavior we wanted), we should be explicit about the directory test.

This is (at best) slow and (at worst) unsafe in the larger context of a filesystem where we do not own things and cannot do things like unlink symlinks that are in our way.

We re-use the `IGNORE_RESET` value for this as it is no longer relevant but has a similar purpose to `IGNORE_FALLBACK`. Similarly, we remove `IGNORE_DEFAULT` which does not have use outside of initializers and move that to fall back to the configuration as well.

submodule: remove the per-repo cache Having this cache and giving them out goes against our multithreading guarantees and it makes it impossible to use submodules in a multi-threaded environment, as any thread can ask for a refresh which may reallocate some string in the submodule struct which we've accessed in a different one via a getter. This makes the submodules behave more like remotes, where each object is created upon request and not shared except explicitly by the user. This means that some tests won't pass yet, as they assume they can affect the submodule objects in the cache and that will affect later operations.

For unintialized error a build warning will be generated. So always keep error variable up-to-date.

Fix index-adding functions to know when to trust filemodes. The idea...sometimes, a filemode is user-specified via an explicit git_index_entry. In this case, believe the user, always. Sometimes, it is instead built up by statting the file system. In those cases, go with the existing logic we have to determine whether the file system supports all filemodes and symlinks, and make the best guess. On file systems which have full filemode and symlink support, this commit should make no difference. On others (most notably Windows), this will fix problems things like: * git_index_add and git_index_add_frombuffer() should be believed. * As a consequence, git_checkout_tree should make the filemodes in the index match the ones in the tree. * And diffs with GIT_DIFF_UPDATE_INDEX don't write the wrong filemodes. * And merges, and probably other downstream stuff now fixed, too. This makes my previous changes to checkout.c unnecessary, so they are now reverted. Also, added a test for index_entry permissions from git_index_add and git_index_add_frombuffer, both of which failed before these changes.

Fix git_checkout_tree() to do index filemodes correctly on Windows. git_checkout_tree() has some fallback behaviors for file systems which don't have full support of filemodes. Generally works fine, but if a given file had a change of type from a 0644 to 0755 (i.e., you add executable permissions), the fallback behavior incorrectly triggers when writing hte updated index. This would cause a git_checkout_tree() command, even with the GIT_CHECKOUT_FORCE option set, to leave a dirty index on Windows. Also added checks to an existing test to catch this case.

config: borrow refcounted references This changes the get_entry() method to return a refcounted version of the config entry, which you have to free when you're done. This allows us to avoid freeing the memory in which the entry is stored on a refresh, which may happen at any time for a live config. For this reason, get_string() has been forbidden on live configs and a new function get_string_buf() has been added, which stores the string in a git_buf which the user then owns. The functions which parse the string value takea advantage of the borrowing to parse safely and then release the entry.

attrcache: don't re-read attrs during checkout During checkout, assume that the .gitattributes files aren't modified during the checkout. Instead, create an "attribute session" during checkout. Assume that attribute data read in the same checkout "session" hasn't been modified since the checkout started. (But allow subsequent checkouts to invalidate the cache.) Further, cache nonexistent git_attr_file data even when .gitattributes files are not found to prevent re-scanning for nonexistent files.

Always checkout with case sensitive iterator On a case-insensitive filesystem, we need to deal with case-changing renames (eg, foo -> FOO) by removing the old and adding the new, exactly as if we were on a case-sensitive filesystem. Update the `checkout::tree::can_cancel_checkout_from_notify` test, now that notifications are always sent case sensitively.

checkout: disallow bad paths on win32 Disallow: 1. paths with trailing dot 2. paths with trailing space 3. paths with trailing colon 4. paths that are 8.3 short names of .git folders ("GIT~1") 5. paths that are reserved path names (COM1, LPT1, etc). 6. paths with reserved DOS characters (colons, asterisks, etc) These paths would (without \\?\ syntax) be elided to other paths - for example, ".git." would be written as ".git". As a result, writing these paths literally (using \\?\ syntax) makes them hard to operate with from the shell, Windows Explorer or other tools. Disallow these.

iterator: submodules are determined by an index or tree We cannot know from looking at .gitmodules whether a directory is a submodule or not. We need the index or tree we are comparing against to tell us. Otherwise we have to assume the entry in .gitmodules is stale or otherwise invalid. Thus we pass the index of the repository into the workdir iterator, even if we do not want to compare against it. This follows what git does, which even for `git diff <tree>`, it will consider staged submodules as such.

Add diff option to update index stat cache When diff is scanning the working directory, if it finds a file where it is not sure if the index entry matches the working dir, it will recalculate the OID (which is pretty expensive). This adds a new flag to diff so that if the OID calculation finds that the file actually has not changed (i.e. just the modified time was altered or such), then it will refresh the stat cache in the index so that future calls to diff will not have to check the oid again.

Lay groundwork for updating stat cache in diff This reorganized the diff OID calculation to make it easier to correctly update the stat cache during a diff once the flags to do so are enabled. This includes marking the path of a git_index_entry as const so we can make a "fake" git_index_entry with a "const char *" path and not get warnings. I was a little surprised at how unobtrusive this change was, but I think it's probably a good thing.
