From: Junio C Hamano Date: Sat, 16 Feb 2008 08:20:37 +0000 (-0800) Subject: Merge branch 'maint' X-Git-Tag: v1.5.5-rc0~220 X-Git-Url: https://git.lorimer.id.au/gitweb.git/diff_plain/d5558581d2583d18cdb6823065a8f812085fbc37?ds=inline;hp=-c Merge branch 'maint' * maint: commit: discard index after setting up partial commit filter-branch: handle filenames that need quoting diff: Fix miscounting of --check output hg-to-git: fix parent analysis mailinfo: feed only one line to handle_filter() for QP input diff.c: add "const" qualifier to "char *cmd" member of "struct ll_diff_driver" Add "const" qualifier to "char *excludes_file". Add "const" qualifier to "char *editor_program". Add "const" qualifier to "char *pager_program". config: add 'git_config_string' to refactor string config variables. diff.c: remove useless check for value != NULL fast-import: check return value from unpack_entry() Validate nicknames of remote branches to prohibit confusing ones diff.c: replace a 'strdup' with 'xstrdup'. diff.c: fixup garding of config parser from value=NULL --- d5558581d2583d18cdb6823065a8f812085fbc37 diff --combined builtin-commit.c index 717eb18da0,45232a11c4..ff6ea0d85e --- a/builtin-commit.c +++ b/builtin-commit.c @@@ -160,7 -160,7 +160,7 @@@ static int list_paths(struct path_list for (i = 0; i < active_nr; i++) { struct cache_entry *ce = active_cache[i]; - if (ce->ce_flags & htons(CE_UPDATE)) + if (ce->ce_flags & CE_UPDATE) continue; if (!pathspec_match(pattern, m, ce->name, 0)) continue; @@@ -317,6 -317,10 +317,10 @@@ static char *prepare_index(int argc, co if (write_cache(fd, active_cache, active_nr) || close_lock_file(&false_lock)) die("unable to write temporary index file"); + + discard_cache(); + read_cache_from(false_lock.filename); + return false_lock.filename; } diff --combined cache.h index 3867ba7ff5,43ba6a3ba5..cdcabe92b6 --- a/cache.h +++ b/cache.h @@@ -3,7 -3,6 +3,7 @@@ #include "git-compat-util.h" #include "strbuf.h" +#include "hash.h" #include SHA1_HEADER #include @@@ -95,84 -94,48 +95,84 @@@ struct cache_time * We save the fields in big-endian order to allow using the * index file over NFS transparently. */ +struct ondisk_cache_entry { + struct cache_time ctime; + struct cache_time mtime; + unsigned int dev; + unsigned int ino; + unsigned int mode; + unsigned int uid; + unsigned int gid; + unsigned int size; + unsigned char sha1[20]; + unsigned short flags; + char name[FLEX_ARRAY]; /* more */ +}; + struct cache_entry { - struct cache_time ce_ctime; - struct cache_time ce_mtime; + struct cache_entry *next; + unsigned int ce_ctime; + unsigned int ce_mtime; unsigned int ce_dev; unsigned int ce_ino; unsigned int ce_mode; unsigned int ce_uid; unsigned int ce_gid; unsigned int ce_size; + unsigned int ce_flags; unsigned char sha1[20]; - unsigned short ce_flags; char name[FLEX_ARRAY]; /* more */ }; #define CE_NAMEMASK (0x0fff) #define CE_STAGEMASK (0x3000) -#define CE_UPDATE (0x4000) #define CE_VALID (0x8000) #define CE_STAGESHIFT 12 -#define create_ce_flags(len, stage) htons((len) | ((stage) << CE_STAGESHIFT)) -#define ce_namelen(ce) (CE_NAMEMASK & ntohs((ce)->ce_flags)) +/* In-memory only */ +#define CE_UPDATE (0x10000) +#define CE_REMOVE (0x20000) +#define CE_UPTODATE (0x40000) +#define CE_UNHASHED (0x80000) + +static inline unsigned create_ce_flags(size_t len, unsigned stage) +{ + if (len >= CE_NAMEMASK) + len = CE_NAMEMASK; + return (len | (stage << CE_STAGESHIFT)); +} + +static inline size_t ce_namelen(const struct cache_entry *ce) +{ + size_t len = ce->ce_flags & CE_NAMEMASK; + if (len < CE_NAMEMASK) + return len; + return strlen(ce->name + CE_NAMEMASK) + CE_NAMEMASK; +} + #define ce_size(ce) cache_entry_size(ce_namelen(ce)) -#define ce_stage(ce) ((CE_STAGEMASK & ntohs((ce)->ce_flags)) >> CE_STAGESHIFT) +#define ondisk_ce_size(ce) ondisk_cache_entry_size(ce_namelen(ce)) +#define ce_stage(ce) ((CE_STAGEMASK & (ce)->ce_flags) >> CE_STAGESHIFT) +#define ce_uptodate(ce) ((ce)->ce_flags & CE_UPTODATE) +#define ce_mark_uptodate(ce) ((ce)->ce_flags |= CE_UPTODATE) #define ce_permissions(mode) (((mode) & 0100) ? 0755 : 0644) static inline unsigned int create_ce_mode(unsigned int mode) { if (S_ISLNK(mode)) - return htonl(S_IFLNK); + return S_IFLNK; if (S_ISDIR(mode) || S_ISGITLINK(mode)) - return htonl(S_IFGITLINK); - return htonl(S_IFREG | ce_permissions(mode)); + return S_IFGITLINK; + return S_IFREG | ce_permissions(mode); } static inline unsigned int ce_mode_from_stat(struct cache_entry *ce, unsigned int mode) { extern int trust_executable_bit, has_symlinks; if (!has_symlinks && S_ISREG(mode) && - ce && S_ISLNK(ntohl(ce->ce_mode))) + ce && S_ISLNK(ce->ce_mode)) return ce->ce_mode; if (!trust_executable_bit && S_ISREG(mode)) { - if (ce && S_ISREG(ntohl(ce->ce_mode))) + if (ce && S_ISREG(ce->ce_mode)) return ce->ce_mode; return create_ce_mode(0666); } @@@ -183,16 -146,14 +183,16 @@@ S_ISLNK(mode) ?
