po/git.pot is normally used as-is and not regenerated by people building git, so it is okay if an explicit "make po/git.pot" always automatically regenerates it. Depend on the magic FORCE target instead of explicitly keeping track of dependencies. This simplifies the makefile, in particular preparing for a moment when $(LIB_H), which is part of $(LOCALIZED_C), can be computed on the fly. It also fixes a slight breakage in which changes to perl and shell scripts did not trigger a rebuild of po/git.pot. We still need a dependency on GENERATED_H, to force those files to be built when regenerating git.pot.

Add a getnanotime() function that returns nanoseconds since 01/01/1970 as unsigned 64-bit integer (i.e. overflows in july 2554). This is easier to work with than e.g. struct timeval or struct timespec. Basing the timer on the epoch allows using the results with other time-related APIs. To simplify adaption to different platforms, split the implementation into a common getnanotime() and a platform-specific highres_nanos() function. The common getnanotime() function handles errors, falling back to gettimeofday() if highres_nanos() isn't implemented or doesn't work. getnanotime() is also responsible for normalizing to the epoch. The offset to the system clock is calculated only once on initialization, i.e. manually setting the system clock has no impact on the timer (except if the fallback gettimeofday() is in use). Git processes are typically short lived, so we don't need to handle clock drift. The highres_nanos() function returns monotonically increasing nanoseconds relative to some arbitrary point in time (e.g. system boot), or 0 on failure. Providing platform-specific implementations should be relatively easy, e.g. adapting to clock_gettime() as defined by the POSIX realtime extensions is seven lines of code. This version includes highres_nanos() implementations for: * Linux: using clock_gettime(CLOCK_MONOTONIC) * Windows: using QueryPerformanceCounter() Todo: * enable clock_gettime() on more platforms * add Mac OSX version, e.g. using mach_absolute_time + mach_timebase_info Signed-off-by: NKarsten Blees <blees@dcon.de> Signed-off-by: NJunio C Hamano <gitster@pobox.com>

Profile feedback always failed for me with -jN. The problem was that there was no implicit ordering between the profile generate stage and the profile use stage. So some objects in the later stage would be linked with profile generate objects, and fail due to the missing -lgcov. This adds a new profile target that implicitely enforces the correct ordering by using submakes. Plus a profile-install target to also install. This is also nicer to type that PROFILE=... Plus I always run the performance test suite now for the full profile run. In addition I also added a profile-fast / profile-fast-install target the only runs the performance test suite instead of the whole test suite. This significantly speeds up the profile build, which was totally dominated by test suite run time. However it may have less coverage of course.

This split-index mode is designed to keep write cost proportional to the number of changes the user has made, not the size of the work tree. (Read cost is another matter, to be dealt separately.) This mode stores index info in a pair of $GIT_DIR/index and $GIT_DIR/sharedindex.<SHA-1>. sharedindex is large and unchanged over time while "index" is smaller and updated often. Format details are in index-format.txt, although not everything is implemented in this patch. Shared indexes are not automatically removed, because it's unclear if the shared index is needed by any (even temporary) indexes by just looking at it. After a while you'll collect stale shared indexes. The good news is one shared index is useable for long, until $GIT_DIR/index becomes too big and sluggish that the new shared index must be created. The safest way to clean shared indexes is to turn off split index mode, so shared files are all garbage, delete them all, then turn on split index mode again.

The function git_wcwidth() returns for a given unicode code point the width on the display: -1 for control characters, 0 for combining or other non-visible code points 1 for e.g. ASCII 2 for double-width code points. This table had been originally been extracted for one Unicode version, probably 3.2. We now use two tables these days, one for zero-width and another for double-width. Make it easier to update these tables to a later version of Unicode by factoring out the table from utf8.c into unicode_width.h and add the script update_unicode.sh to update the table based on the latest Unicode specification files.

The original implementation of CURL_CONFIG support did not match the original behavior of using -lcurl when CURLDIR was not set. This broke implementations that were lacking curl-config but did have libcurl installed along system libraries, such as MSysGit. In other words, the assumption that curl-config is always installed was incorrect. Instead, if CURL_CONFIG is empty or returns an empty result (e.g. due to curl-config being missing), use the old behavior of falling back to -lcurl.

For example in the following code block, the comment in line 2 will be extracted as comment for the l10n message in line 3, but obviously it's wrong. { OPTION_CALLBACK, 0, "ignore-removal", &addremove_explicit, NULL /* takes no arguments */, N_("ignore paths removed in the working tree (same as --no-all)"), PARSE_OPT_NOARG, ignore_removal_cb }, Since almost all comments for l10n translators are marked with the same prefix (tag): "TRANSLATORS:", it's safe to only extract comments with this special tag. I.E. it's better to call xgettext as: xgettext --add-comments=TRANSLATORS: ... Also tweaks the multi-line comment in "init-db.c", to make it start with the proper tag, not "* TRANSLATORS:" (which has a star before the tag).

Multi-threaing of index-pack was disabled with c0f86547 (index-pack: Disable threading on cygwin - 2012-06-26), because pread() implementations for Cygwin and MSYS were not thread safe. Recent Cygwin does offer usable pread() and we enabled multi-threading with 103d530f (Cygwin 1.7 has thread-safe pread, 2013-07-19). Work around this problem on platforms with a thread-unsafe pread() emulation by opening one file handle per thread; it would prevent parallel pread() on different file handles from stepping on each other. Also remove NO_THREAD_SAFE_PREAD that was introduced in c0f86547 because it's no longer used anywhere. This workaround is unconditional, even for platforms with thread-safe pread() because the overhead is small (a couple file handles more) and not worth fragmenting the code.

curl-config should always be installed alongside a curl distribution, and its purpose is to provide flags for building against libcurl, so use it instead of guessing flags and dependent libraries. Allow overriding CURL_CONFIG to a custom path to curl-config, to compile against a curl installation other than the first in PATH. Depending on the set of features curl is compiled with, there may be more libraries required than the previous two options of -lssl and -lidn. For example, with a vanilla build of libcurl-7.36.0 on Mac OS X 10.9: $ ~/d/curl-out-7.36.0/lib/curl-config --libs -L/Users/dborowitz/d/curl-out-7.36.0/lib -lcurl -lgssapi_krb5 -lresolv -lldap -lz Use this only when CURLDIR is not explicitly specified, to continue supporting older builds.

In the next patch we'll have to use alloca() for performance reasons, but since alloca is non-standardized and is not portable, let's have a trick with compatibility wrappers: 1. at configure time, determine, do we have working alloca() through alloca.h, and define #define HAVE_ALLOCA_H if yes. 2. in code #ifdef HAVE_ALLOCA_H # include <alloca.h> # define xalloca(size) (alloca(size)) # define xalloca_free(p) do {} while(0) #else # define xalloca(size) (xmalloc(size)) # define xalloca_free(p) (free(p)) #endif and use it like func() { p = xalloca(size); ... xalloca_free(p); } This way, for systems, where alloca is available, we'll have optimal on-stack allocations with fast executions. On the other hand, on systems, where alloca is not available, this gracefully fallbacks to xmalloc/free. Both autoconf and config.mak.uname configurations were updated. For autoconf, we are not bothering considering cases, when no alloca.h is available, but alloca() works some other way - its simply alloca.h is available and works or not, everything else is deep legacy. For config.mak.uname, I've tried to make my almost-sure guess for where alloca() is available, but since I only have access to Linux it is the only change I can be sure about myself, with relevant to other changed systems people Cc'ed. NOTE SunOS and Windows had explicit -DHAVE_ALLOCA_H in their configurations. I've changed that to now-common HAVE_ALLOCA_H=YesPlease which should be correct.

These version numbers are intended for machine consumption. They are typically inspected by installers to decide whether a file to be installed is newer than one that exists on the system, but are not used for much else. We can be pretty certain that there are no tools that look at these version numbers, not even the installer of Git for Windows does.

This commit extends more the functionality of `pack-objects` by allowing it to write out a `.bitmap` index next to any written packs, together with the `.idx` index that currently gets written. If bitmap writing is enabled for a given repository (either by calling `pack-objects` with the `--write-bitmap-index` flag or by having `pack.writebitmaps` set to `true` in the config) and pack-objects is writing a packfile that would normally be indexed (i.e. not piping to stdout), we will attempt to write the corresponding bitmap index for the packfile. Bitmap index writing happens after the packfile and its index has been successfully written to disk (`finish_tmp_packfile`). The process is performed in several steps: 1. `bitmap_writer_set_checksum`: this call stores the partial checksum for the packfile being written; the checksum will be written in the resulting bitmap index to verify its integrity 2. `bitmap_writer_build_type_index`: this call uses the array of `struct object_entry` that has just been sorted when writing out the actual packfile index to disk to generate 4 type-index bitmaps (one for each object type). These bitmaps have their nth bit set if the given object is of the bitmap's type. E.g. the nth bit of the Commits bitmap will be 1 if the nth object in the packfile index is a commit. This is a very cheap operation because the bitmap writing code has access to the metadata stored in the `struct object_entry` array, and hence the real type for each object in the packfile. 3. `bitmap_writer_reuse_bitmaps`: if there exists an existing bitmap index for one of the packfiles we're trying to repack, this call will efficiently rebuild the existing bitmaps so they can be reused on the new index. All the existing bitmaps will be stored in a `reuse` hash table, and the commit selection phase will prioritize these when selecting, as they can be written directly to the new index without having to perform a revision walk to fill the bitmap. This can greatly speed up the repack of a repository that already has bitmaps. 4. `bitmap_writer_select_commits`: if bitmap writing is enabled for a given `pack-objects` run, the sequence of commits generated during the Counting Objects phase will be stored in an array. We then use that array to build up the list of selected commits. Writing a bitmap in the index for each object in the repository would be cost-prohibitive, so we use a simple heuristic to pick the commits that will be indexed with bitmaps. The current heuristics are a simplified version of JGit's original implementation. We select a higher density of commits depending on their age: the 100 most recent commits are always selected, after that we pick 1 commit of each 100, and the gap increases as the commits grow older. On top of that, we make sure that every single branch that has not been merged (all the tips that would be required from a clone) gets their own bitmap, and when selecting commits between a gap, we tend to prioritize the commit with the most parents. Do note that there is no right/wrong way to perform commit selection; different selection algorithms will result in different commits being selected, but there's no such thing as "missing a commit". The bitmap walker algorithm implemented in `prepare_bitmap_walk` is able to adapt to missing bitmaps by performing manual walks that complete the bitmap: the ideal selection algorithm, however, would select the commits that are more likely to be used as roots for a walk in the future (e.g. the tips of each branch, and so on) to ensure a bitmap for them is always available. 5. `bitmap_writer_build`: this is the computationally expensive part of bitmap generation. Based on the list of commits that were selected in the previous step, we perform several incremental walks to generate the bitmap for each commit. The walks begin from the oldest commit, and are built up incrementally for each branch. E.g. consider this dag where A, B, C, D, E, F are the selected commits, and a, b, c, e are a chunk of simplified history that will not receive bitmaps. A---a---B--b--C--c--D \ E--e--F We start by building the bitmap for A, using A as the root for a revision walk and marking all the objects that are reachable until the walk is over. Once this bitmap is stored, we reuse the bitmap walker to perform the walk for B, assuming that once we reach A again, the walk will be terminated because A has already been SEEN on the previous walk. This process is repeated for C, and D, but when we try to generate the bitmaps for E, we can reuse neither the current walk nor the bitmap we have generated so far. What we do now is resetting both the walk and clearing the bitmap, and performing the walk from scratch using E as the origin. This new walk, however, does not need to be completed. Once we hit B, we can lookup the bitmap we have already stored for that commit and OR it with the existing bitmap we've composed so far, allowing us to limit the walk early. After all the bitmaps have been generated, another iteration through the list of commits is performed to find the best XOR offsets for compression before writing them to disk. Because of the incremental nature of these bitmaps, XORing one of them with its predecesor results in a minimal "bitmap delta" most of the time. We can write this delta to the on-disk bitmap index, and then re-compose the original bitmaps by XORing them again when loaded. This is a phase very similar to pack-object's `find_delta` (using bitmaps instead of objects, of course), except the heuristics have been greatly simplified: we only check the 10 bitmaps before any given one to find best compressing one. This gives good results in practice, because there is locality in the ordering of the objects (and therefore bitmaps) in the packfile. 6. `bitmap_writer_finish`: the last step in the process is serializing to disk all the bitmap data that has been generated in the two previous steps. The bitmap is written to a tmp file and then moved atomically to its final destination, using the same process as `pack-write.c:write_idx_file`.

A bitmap index is a `.bitmap` file that can be found inside `$GIT_DIR/objects/pack/`, next to its corresponding packfile, and contains precalculated reachability information for selected commits. The full specification of the format for these bitmap indexes can be found in `Documentation/technical/bitmap-format.txt`. For a given commit SHA1, if it happens to be available in the bitmap index, its bitmap will represent every single object that is reachable from the commit itself. The nth bit in the bitmap is the nth object in the packfile; if it's set to 1, the object is reachable. By using the bitmaps available in the index, this commit implements several new functions: - `prepare_bitmap_git` - `prepare_bitmap_walk` - `traverse_bitmap_commit_list` - `reuse_partial_packfile_from_bitmap` The `prepare_bitmap_walk` function tries to build a bitmap of all the objects that can be reached from the commit roots of a given `rev_info` struct by using the following algorithm: - If all the interesting commits for a revision walk are available in the index, the resulting reachability bitmap is the bitwise OR of all the individual bitmaps. - When the full set of WANTs is not available in the index, we perform a partial revision walk using the commits that don't have bitmaps as roots, and limiting the revision walk as soon as we reach a commit that has a corresponding bitmap. The earlier OR'ed bitmap with all the indexed commits can now be completed as this walk progresses, so the end result is the full reachability list. - For revision walks with a HAVEs set (a set of commits that are deemed uninteresting), first we perform the same method as for the WANTs, but using our HAVEs as roots, in order to obtain a full reachability bitmap of all the uninteresting commits. This bitmap then can be used to: a) limit the subsequent walk when building the WANTs bitmap b) finding the final set of interesting commits by performing an AND-NOT of the WANTs and the HAVEs. If `prepare_bitmap_walk` runs successfully, the resulting bitmap is stored and the equivalent of a `traverse_commit_list` call can be performed by using `traverse_bitmap_commit_list`; the bitmap version of this call yields the objects straight from the packfile index (without having to look them up or parse them) and hence is several orders of magnitude faster. As an extra optimization, when `prepare_bitmap_walk` succeeds, the `reuse_partial_packfile_from_bitmap` call can be attempted: it will find the amount of objects at the beginning of the on-disk packfile that can be reused as-is, and return an offset into the packfile. The source packfile can then be loaded and the bytes up to `offset` can be written directly to the result without having to consider the entires inside the packfile individually. If the `prepare_bitmap_walk` call fails (e.g. because no bitmap files are available), the `rev_info` struct is left untouched, and can be used to perform a manual rev-walk using `traverse_commit_list`. Hence, this new set of functions are a generic API that allows to perform the equivalent of git rev-list --objects [roots...] [^uninteresting...] for any set of commits, even if they don't have specific bitmaps generated for them. In further patches, we'll use this bitmap traversal optimization to speed up the `pack-objects` and `rev-list` commands.

EWAH is a word-aligned compressed variant of a bitset (i.e. a data structure that acts as a 0-indexed boolean array for many entries). It uses a 64-bit run-length encoding (RLE) compression scheme, trading some compression for better processing speed. The goal of this word-aligned implementation is not to achieve the best compression, but rather to improve query processing time. As it stands right now, this EWAH implementation will always be more efficient storage-wise than its uncompressed alternative. EWAH arrays will be used as the on-disk format to store reachability bitmaps for all objects in a repository while keeping reasonable sizes, in the same way that JGit does. This EWAH implementation is a mostly straightforward port of the original `javaewah` library that JGit currently uses. The library is self-contained and has been embedded whole (4 files) inside the `ewah` folder to ease redistribution. The library is re-licensed under the GPLv2 with the permission of Daniel Lemire, the original author. The source code for the C version can be found on GitHub: https://github.com/vmg/libewok The original Java implementation can also be found on GitHub: https://github.com/lemire/javaewah [jc: stripped debug-only code per Peff's $gmane/239768] Signed-off-by: NVicent Marti <tanoku@gmail.com> Signed-off-by: NJeff King <peff@peff.net> Helped-by: NRamsay Jones <ramsay@ramsay1.demon.co.uk> Signed-off-by: NJunio C Hamano <gitster@pobox.com>

When the built-in "git tar-tree" command (a thin wrapper around "git archive") was removed in 925ceccf (tar-tree: remove deprecated command, 2013-11-10), the build continued to install a non-functioning git-tar-tree command in gitexecdir by mistake: $ PATH=$(git --exec-path):$PATH $ git-tar-tree -h fatal: cannot handle tar-tree internally The list of links in gitexecdir is populated from BUILTIN_OBJS, which includes builtin/tar-tree.o to implement "git get-tar-commit-id". Rename the get-tar-commit-id source file to builtin/get-tar-commit-id.c to reflect its purpose and fix 'make install'.

Some platforms ship Perl modules used by git scripts outside the default perl path (e.g., on Mac OS X, Subversion's perl bindings live in a separate xcode perl path). Add an PERLLIB_EXTRA variable to hold a colon-separated list of extra directories to add to the perl path in git's scripts, as a convenience for packagers.

The existing hashtable implementation (in hash.[ch]) uses open addressing (i.e. resolve hash collisions by distributing entries across the table). Thus, removal is difficult to implement with less than O(n) complexity. Resolving collisions of entries with identical hashes (e.g. via chaining) is left to the client code. Add a hashtable implementation that supports O(1) removal and is slightly easier to use due to builtin entry chaining. Supports all basic operations init, free, get, add, remove and iteration. Also includes ready-to-use hash functions based on the public domain FNV-1 algorithm (http://www.isthe.com/chongo/tech/comp/fnv). The per-entry data structure (hashmap_entry) is piggybacked in front of the client's data structure to save memory. See test-hashmap.c for usage examples. The hashtable is resized by a factor of four when 80% full. With these settings, average memory consumption is about 2/3 of hash.[ch], and insertion is about twice as fast due to less frequent resizing. Lookups are also slightly faster, because entries are strictly confined to their bucket (i.e. no data of other buckets needs to be traversed).

The hash table that stores the packing list for a given `pack-objects` run was tightly coupled to the pack-objects code. In this commit, we refactor the hash table and the underlying storage array into a `packing_data` struct. The functionality for accessing and adding entries to the packing list is hence accessible from other parts of Git besides the `pack-objects` builtin. This refactoring is a requirement for further patches in this series that will require accessing the commit packing list from outside of `pack-objects`. The hash table implementation has been minimally altered: we now use table sizes which are always a power of two, to ensure a uniform index distribution in the array.

Sparse issues an "using sizeof on a function" warning for each call to curl_easy_setopt() which sets an option that takes a function pointer parameter. (currently 12 such warnings over 4 files.) The warnings relate to the use of the "typecheck-gcc.h" header file which adds a layer of type-checking macros to the curl function invocations (for gcc >= 4.3 and !__cplusplus). As part of the type-checking layer, 'sizeof' is applied to the function parameter of curl_easy_setopt(). Note that, in the context of sizeof, the function to function pointer conversion is not performed and that sizeof(f) != sizeof(&f). A simple solution, therefore, would be to replace the function name in each such call to curl_easy_setopt() with an explicit function pointer expression (i.e. replace f with &f). However, the "typecheck-gcc.h" header file is only conditionally included, in addition to the gcc and C++ checks mentioned above, depending on the CURL_DISABLE_TYPECHECK preprocessor variable. In order to suppress the warnings, we use target-specific variable assignments to add -DCURL_DISABLE_TYPECHECK to SPARSE_FLAGS for each file affected (http-push.c, http.c, http-walker.c and remote-curl.c).

The motivation of this patch is to get closer to a goal of being able to have a core subset of git functionality built in to git. That would mean * people on Windows could get a copy of at least the core parts of Git without having to install a Unix-style shell * people using git in on servers with chrooted environments do not need to worry about standard tools lacking for shell scripts. This patch is meant to be mostly a literal translation of the git-repack script; the intent is that later patches would start using more library facilities, but this patch is meant to be as close to a no-op as possible so it doesn't do that kind of thing.

When it was originally added, the git_remote_helpers library was used as part of the tests of the remote-helper interface, but since commit fc407f98 (Add new simplified git-remote-testgit, 2012-11-28) a simple shell script is used for this. A search on Ohloh [1] indicates that this library isn't used by any external projects and even the Python remote helpers in contrib/ don't use this library, so it is only used by its own test suite. Since this is the only Python library in Git, removing it will make packaging easier as the Python scripts only need to be installed for one version of Python, whereas the library should be installed for all available versions.
