starts with an octal digit. From Andreas Gruenbacher.
|
|
|
|
|
|
xstrtol.h, stdbool.h, stddef.h: Don't include; no longer needed.
(MODE_DONE): New constant.
(struct mode_change): Remove 'next' member.
(make_node_op_equals): New function; like the old one of the
same name, except it allocates an array.
(mode_compile, mode_create_from_ref): Use it.
(mode_compile): Allocate result as an array, not a linked list.
Parse octal string ourself, so that we catch mistakes like "+0".
(mode_adjust): Arg is an array, not a linked list.

(S_ISDIR, S_ISUID, S_ISGID, S_ISVTX, S_IRUSR, S_IWUSR, S_IXUSR):
(S_IRGRP, S_IWGRP, S_IXGRP, S_IROTH, S_IWOTH, S_IXOTH, S_IRXWU):
(S_IRWXG, S_IRWXO, CHMOD_MODE_BITS):
Remove. This is now stat-macros.h's job.
(talloc): Remove. All callers replaced by xalloc, so that
our invokers don't have to worry about reporting memory failures.
(make_node_op_equals): Remove.
(MODE_ORDINARY_CHAGE, MODE_X_IF_ANY_X, MODE_COPY_EXISTING):
New constants.
(struct mode_change): Moved here from modechange.h.
(mode_append_entry): Remove.
(mode_compile): Remove MASKED_OPS arg, since it encouraged
apps to have incorrect behavior. Use simpler algorithm for head
and tail. Don't futz with umask; that's now the job of mode_adjust.
Detect more invalid usages rather than having somewhat-random behavior.
Don't insert an "a=" action, as that leads to incorrect behavior.
(mode_compile, mode_create_from_ref): Return NULL on error instead
of an enum, since now there's only one way to have an error. All
callers changed.
(mode_adjust): Accept new arg UMASK_VALUE, and interpret it
at the correct time. Simplify calculation of "+u" and its ilk.
Don't mishandle "+X".
(mode_free): Remove "register" and localize decls.

points to the start of a string, as the C Standard says the
resulting behavior is undefined.
|
|
|
|
(mode_compile): Use bool when appropriate.
|
|
(malloc): Remove decl.
|
|
(NULL): Don't define, since <stddef.h> does that.
|
|
`signed and unsigned type in conditional expression'.

that made e.g., `chmod a=,o=w,g=o F' cause F to be group readable
rather than group writable. Patch by Juan F. Codagnone.

traditional octal encoding. E.g. "chmod 1 FOO" should set
the other-execute bit of FOO even if S_IXOTH != 1.
(SUID, SGID, SVTX, RUSR, WUSR, XUSR, RGRP, WGRP, XGRP, ROTH,
WOTH, XOTH, ALLM): New macros.
(S_ISUID, S_ISGID, S_ISVTX, S_IRUSR, S_IWUSR, S_IXUSR,
S_IRGRP, S_IWGRP, S_IXGRP, S_IROTH, S_IWOTH, S_IXOTH):
Use them.
(S_ISGID): Fix typo; it was defaulting to the same value as S_ISUID.
(S_IRWXU, S_IRWXG, S_IRWXO): Specify defaults in terms of the above.
(mode_compile):
No need to use uintmax_t; unsigned long is long enough.
Don't bother to get suffix since we don't use it.

changed this year other than in the copyright notice.

long, to parse numeric modes. Check for any unknown bits, not
just unknown bits left of the leftmost known bit.
|
|
Use proper mode_t types and macros.
Don't assume the traditional Unix values for mode bits.
modechange.h now includes sys/types.h.
Include xstrtol.h.
(isodigit, oatoi): Remove.
(S_ISUID, S_ISGID, S_ISVTX, S_IRUSR, S_IWUSR, S_IXUSR, S_IRGRP,
S_IWGRP, S_IXGRP, S_IROTH, S_IWOTH, S_IXOTH, S_IRWXU, S_IRWXG,
S_IRWXO): Define if not defined.
(CHMOD_MODE_BITS): New macro.
(mode_compile): Convert from octal with xstrtoul, not our own routine.
|
|
(mode_append_entry): Likewise.
(mode_compile): When none of [ugoa] is specified in an `=OP' change
mode request, insert a `=0' entry into the linked list so that all
bits are cleared first. Use the new functions.
|
|
everything starting with the head, not the tail.
|
|
|
|
|
|
|
|
|
|
Don't use MODE_X_IF_ANY_X.
|
|
|
|
|
|
|
|
|
|
Remove register attribute.
(mode_adjust): Likewise for CHANGES.
