* | applet_tables: simulate force-renaming on WindowsJohannes Schindelin2021-02-211-0/+9
|/ | | | | | | | | | On Windows, you cannot `rename(source, target)` if `target` exists or if a file handle to `source` is still open. This patch is similar in spirit to 02958a6ee (kbuild: simulate force-renaming on Windows, 2017-02-01). Signed-off-by: Johannes Schindelin <johannes.schindelin@gmx.de>

* build system: prevent duplicate applet namesRon Yorston2018-11-271-1/+9
| | | | | | | | | | | | The embedded script feature makes it easier to create applets with duplicate names. Currently in such cases the build succeeds but the resulting executable doesn't work as the developer intended. Catch duplicate names when the applet tables are being generated and make the build fail. Signed-off-by: Ron Yorston <rmy@pobox.com> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>
* build system: fix parallel building issueMichael Olbrich2018-04-141-2/+14
| | | | | | | | | | | | | | | | The files generated by the include/config/MARKER target are in the dependency list for applets/applet_tables. If applets/applet_tables is created first during applets_dir then it will be created again later as part of $(busybox-dirs). As a result include/applet_tables.h is created again. This time while other build commands may need it. Let applets_dir depend on include/config/MARKER to avoid this particular race condition and create the header files atomically to ensure that the compiler never sees incomplete files.

* build system: always rewrite NUM_APPLETS.hDenys Vlasenko2016-08-231-10/+11
| | | | | | | Conditional rewrite can keep NUM_APPLETS.h mtime old, this causes make to try to regenerate it at every invocation. Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>

| | | | | | | | On user request. I thought enabling/disabling them all together is more consistent. Evidently, some people do want them to be separately selectable. Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>

* applet_tables: save space by removing applet name offsetsRon Yorston2016-03-301-18/+60
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The array applet_nameofs consumes two bytes per applet. It encodes nofork/noexec flags suid flags the offset of the applet name in the applet_name string Change the applet_table build tool to store the flags in two separate arrays (applet_flags and applet_suid). Replace applet_nameofs[] with a smaller version that only stores a limited number of offsets. This requires changes to the macros APPLET_IS_NOFORK, APPLET_IS_NOEXEC and APPLET_SUID. According to Valgrind the original find_applet_by_name required 353 cycles per call, averaged over all names. Adjusting the number of known offsets allows space to be traded off against execution time: KNOWN_OFFSETS cycles bytes (wrt KNOWN_OFFSETS = 0) 0 9057 - 2 4604 32 4 2407 75 8 1342 98 16 908 130 32 884 194 This patch uses KNOWN_OFFSETS = 8. v2: Remove some dead code from the applet_table tool; Treat the applet in the middle of the table as a special case. v3: Use the middle applet to adjust the start of the linear search as well as the last applet found. v4: Use an augmented linear search in find_applet_by_name. Drop the special treatment of the middle name from get_applet_name: most of the advantage now derives from the last stored value. v5: Don't store index in applet_nameofs, it can be calculated. v6: Tweaks by Denys function old new delta find_applet_by_name 25 125 +100 applet_suid - 92 +92 run_applet_no_and_exit 452 460 +8 run_applet_and_exit 695 697 +2 applet_name_compare 31 - -31 applet_nameofs 734 14 -720 ------------------------------------------------------------------------------ (add/remove: 1/1 grow/shrink: 3/1 up/down: 202/-751) Total: -549 bytes text data bss dec hex filename 925464 906 17160 943530 e65aa busybox_old 924915 906 17160 942981 e6385 busybox_unstripped Signed-off-by: Ron Yorston <rmy@pobox.com> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>
