* builtin-apply: Show a more descriptive error on failure when opening a patchAlberto Bertogli2008-04-15
| | | | | | | | | When a patch can't be opened (it doesn't exist, there are permission problems, etc.) we get the usage text, which is not a proper indication of failure. Signed-off-by: Alberto Bertogli <albertito@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
* Fix "git apply" to correctly enforce "match at the beginning"Junio C Hamano2008-04-06
| | | | | | | | | | | | | | | | | An earlier commit 4be6096 (apply --unidiff-zero: loosen sanity checks for --unidiff=0 patches, 2006-09-17) made match_beginning and match_end computed incorrectly. If a hunk inserts at the beginning, old position recorded at the hunk is line 0, and if a hunk changes at the beginning, it is line 1. The new test added to t4104 exposes that the old code did not insist on matching at the beginning for a patch to add a line to an empty file. An even older 65aadb9 (apply: force matching at the beginning., 2006-05-24) was equally wrong in that it tried to take hints from the number of leading context lines, to decide if the hunk must match at the beginning, but we can just look at the line number in the hunk to decide.

* "git-apply --check" should not report "fixed"Junio C Hamano2008-01-08
| | | | | | | | | | | | | | | When running "git apply --check" while --whitespace=fix is enabled (either from the command line or via the configuration), we reported that "N line(s) applied after _fixing_", but --check by itself does not apply and this message was alarming. We could even reword the message to say "N line(s) would have been applied after fixing...", but this patch does not go that far. Instead, we just make it use the "N lines add whitespace errors" warning, which happens to be a good diagnostic message a user would expect from the --check option.

* Make "diff --check" output match "git apply"Wincent Colaiuta2007-12-13
| | | | | | | | | | | | | | | For consistency, make the two tools report whitespace errors in the same way (the output of "diff --check" has been tweaked to match that of "git apply"). Note that although the textual content is basically the same only "git diff --check" provides a colorized version of the problematic lines; making "git apply" do colorization will require more extensive changes (figuring out the diff colorization preferences of the user) and so that will be a subject for another commit.

* Unify whitespace checkingWincent Colaiuta2007-12-13
| | | | | | | | | | | | | | | | | | | | | | | | | | This commit unifies three separate places where whitespace checking was performed: - the whitespace checking previously done in builtin-apply.c is extracted into a function in ws.c - the equivalent logic in "git diff" is removed - the emit_line_with_ws() function is also removed because that also rechecks the whitespace, and its functionality is rolled into ws.c The new function is called check_and_emit_line() and it does two things: checks a line for whitespace errors and optionally emits it. The checking is based on lines of content rather than patch lines (in other words, the caller must strip the leading "+" or "-"); this was suggested by Junio on the mailing list to allow for a future extension to "git show" to display whitespace errors in blobs. At the same time we teach it to report all classes of whitespace errors found for a given line rather than reporting only the first found error.

| * Use gitattributes to define per-path whitespace ruleJunio C Hamano2007-12-06
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The `core.whitespace` configuration variable allows you to define what `diff` and `apply` should consider whitespace errors for all paths in the project (See gitlink:git-config[1]). This attribute gives you finer control per path. For example, if you have these in the .gitattributes: frotz whitespace nitfol -whitespace xyzzy whitespace=-trailing all types of whitespace problems known to git are noticed in path 'frotz' (i.e. diff shows them in diff.whitespace color, and apply warns about them), no whitespace problem is noticed in path 'nitfol', and the default types of whitespace problems except "trailing whitespace" are noticed for path 'xyzzy'.

| | | | | | | | | | | | | | | | | | | | We earlier introduced core.whitespace to allow users to tweak the definition of what the "whitespace errors" are, for the purpose of diff output highlighting.

| * builtin-apply: rename "whitespace" variables and fix stylesJunio C Hamano2007-11-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The variables were somewhat misnamed. * "What to do when whitespace errors are detected" is now called "ws_error_action" (used to be called "new_whitespace"); * The constants to denote the possible actions are "nowarn_ws_error", "warn_on_ws_error", "die_on_ws_error", and "correct_ws_error". The last one used to be "strip_whitespace", but we correct whitespace error in indent (SP followed by HT) and "strip" is not quite an accurate name for it. Other than the renaming of variables and constants, there is no functional change in this patch. While we are at it, it also fixes overly long lines and multi-line comment styles (which of course do not affect the generated code at all). Signed-off-by: Junio C Hamano <gitster@pobox.com>

It is made a char * so that we can sloppily accept things that perform: sb->buf[0] = '\0', and because you can't pass "" as an initializer for ->buf without making gcc unhappy for very good reasons. strbuf_init/_detach/_grow have been fixed to trust ->alloc and not ->buf anymore. as a consequence strbuf_detach is _mandatory_ to detach a buffer, copying ->buf isn't an option anymore, if ->buf is going to escape from the scope, and eventually be free'd. API changes: * strbuf_setlen now always works, so just make strbuf_reset a convenience macro. * strbuf_detatch takes a size_t* optional argument (meaning it can be NULL) to copy the buffer's len, as it was needed for this refactor to make the code more readable, and working like the callers.

Now instead of asking for quotes or not, you pass a "terminator". If it's \0 then we assume you don't want to escape, else C escaping is performed. In any case, the terminator is also appended to the stream. It also no longer takes the prefix/prefix_len arguments, as it's seldomly used, and makes some optimizations harder. * write_name_quotedpfx is created to work like write_name_quoted and take the prefix/prefix_len arguments. Thanks to those API changes, diff.c has somehow lost weight, thanks to the removal of functions that were wrappers around the old write_name_quoted trying to give it a semantics like the new one, but performing a lot of allocations for this goal. Now we always write directly to the stream, no intermediate allocation is performed. As a side effect of the refactor in builtin-apply.c, the length of the bar graphs in diffstats are not affected anymore by the fact that the path was clipped.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If the gain is not obvious in the diffstat, the resulting code is more readable, _and_ in checkout-index/update-index we now reuse the same buffer to unquote strings instead of always freeing/mallocing. This also is more coherent with the next patch that reworks quoting functions. The quoting function is also made more efficient scanning for backslashes and treating portions of strings without a backslash at once. Signed-off-by: Pierre Habouzit <madcoder@debian.org>

In that case, it also returns 1, else it returns 0. * those functions support "in place" editing, in the sense that it's OK to call them this way: convert_to_git(path, sb->buf, sb->len, sb); When doable, conversions are done in place for real, else the strbuf content is just replaced with the new one, transparentely for the caller. If you want to create a new filter working this way, being the accumulation of filter1, filter2, ... filtern, then your meta_filter would be: int meta_filter(..., const char *src, size_t len, struct strbuf *sb) { int ret = 0; ret |= filter1(...., src, len, sb); if (ret) { src = sb->buf; len = sb->len; } ret |= filter2(...., src, len, sb); if (ret) { src = sb->buf; len = sb->len; } .... return ret | filtern(..., src, len, sb); } That's why subfilters the convert_to_* functions called were also rewritten to work this way.

This is not critical as the growth mechanism chosen will always allocate _more_ memory than asked, so the second test will not fail. It's some kind of miracle though. * Add size extension hints for strbuf_init and strbuf_read.

This led to a few bugs due to missed invalidate calls already. This patch makes the management of cache-tree less error prone by making more invalidate calls from lower level cache API functions. The rules are: - If you are going to write the index, you should either maintain cache_tree correctly. - If you cannot, alternatively you can remove the entire cache_tree by calling cache_tree_free() before you call write_cache(). - When you modify the index, cache_tree_invalidate_path() should be called with the path you are modifying, to discard the entry from the cache-tree structure. - The following cache API functions exported from read-cache.c (and the macro whose names have "cache" instead of "index") automatically call cache_tree_invalidate_path() for you: - remove_file_from_index(); - add_file_to_index(); - add_index_entry(); You can modify the index bypassing the above API functions (e.g. find an existing cache entry from the index and modify it in place). You need to call cache_tree_invalidate_path() yourself in such a case. Signed-off-by: Junio C Hamano <gitster@pobox.com>

* git-apply: do not read past the end of bufferJunio C Hamano2007-09-05
| | | | | | | | | | | | | | | | When the preimage we are patching is shorter than what the patch text expects, we tried to match the buffer contents at the "original" line with the fragment in full, without checking we have enough data to match in the preimage. This caused the size of a later memmove() to wrap around and attempt to scribble almost the entire address space. Not good. The code that follows the part this patch touches tries to match the fragment with line offsets. Curiously, that code does not have the problem --- it guards against reading past the end of the preimage. Signed-off-by: Junio C Hamano <gitster@pobox.com>

As usual in the current git, only the superproject itself is actually modified (possibly creating empty directories for new submodules). Any checked-out submodule is left untouched and is not required to be up-to-date. With clean-ups from Junio C Hamano.

| | | | | | | | | | | | | | | | | | We attempt to remove directory that becomes empty after removal of a file. We should do the same when we rename an existing file away. Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> Signed-off-by: Junio C Hamano <gitster@pobox.com>

| | | | | | | | | | | | | | | | | | | | "git apply" used to take check the whitespace in the wrong direction. Noticed by Daniel Barkalow. Signed-off-by: Johannes Schindelin <johannes.schindelin@gmx.de> Signed-off-by: Junio C Hamano <gitster@pobox.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The earlier code removed one newline too many from the hunk that adds new lines at the end of the file. Also the way the code counted the added blank lines was somewhat roundabout; I think the way updated code does it is more direct and easier to follow: * We keep track of the number of blank lines added; * While processing each line, we notice if it adds a blank line, and increment the counter, or reset it to zero otherwise; * When actually we apply the data, we remove the empty lines we counted earlier if we are applying it at the end of the file.
