2018-11-29vi: fix FEATURE_VI_REGEX_SEARCH to respect LIMITED (one-line) searchDenys Vlasenko
If busybox is compiled with FEATURE_VI_REGEX_SEARCH enabled, command ":s/x/y/" searches not only in the current line, but continues search after it. This makes range searches (":1,3s/x/y/") work incorrect. For example file "./test": 1 2 3 $ vi ./test :1,2s/3/e/ gives us: 1 2 e function old new delta char_search 213 241 +28 Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>

2018-11-27hush: allow hush to run embedded scriptsRon Yorston
Embedded scripts require a shell to be present in the BusyBox binary. Allow either ash or hush to be used for this purpose. If both are enabled ash takes precedence. The size of the binary is unchanged in the default configuration: both ash and hush are present but support for embedded scripts isn't compiled into hush.

2018-11-27build system: prevent duplicate applet namesRon Yorston
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>
2018-11-27Tweaks to build process for embedded scriptsRon Yorston
- Force a rebuild if a script in applets_sh is changed. - Move the dummy usage messages for custom applets to usage.h and change the name from 'dummy' to 'scripted'. - Hide an error from gen_build_files.sh if an embed directory exists but is empty. - Tidy up embedded_scripts script. v2: Remove a couple of unnecessary tests in embedded_scripts, as pointed out by Xabier Oneca.

2018-11-20ash: reset tokpushback before prompting while parsing heredocChristoph Schulz
The parser reads from an already freed memory location, thereby causing unpredictable results, in the following situation: - ENABLE_ASH_EXPAND_PRMT is enabled - heredoc is being parsed - command substitution is used within heredoc Examples where this bug crops up are (PS2 is set to "> "): $ cat <<EOF > `echo abc` > EOF -sh: O: not found $ cat <<EOF > $(echo abc) > EOF -sh: {garbage}: not found The presumable reason is that setprompt_if() causes a nested expansion when ENABLE_ASH_EXPAND_PRMT is enabled, therefore leaving "wordtext" in an unusable state. However, when parseheredoc() is called, "tokpushback" is non-zero, which causes the next call to xxreadtoken() to return TWORD, causing the caller to use the invalid "wordtoken" instead of reading the next valid token. The call chain is: list() -> peektoken() [sets tokpushback to 1] -> parseheredoc() -> setprompt_if() -> pushstackmark() -> expandstr() -> readtoken1() [sets lasttoken to TWORD, wordtoken points to expanded prompt] -> popstackmark() [invalidates wordtoken, leaves lasttoken as is] -> readtoken1() -> ...parsebackq -> list() -> andor() -> pipeline() -> readtoken() -> xxreadtoken() [tokpushback non-zero, reuse lasttoken and wordtext] Note that in almost all other contexts, each call to setprompt_if() is preceded by setting "tokpushback" to zero. One exception is "oldstyle" backquote parsing in readtoken1(), but there "tokpushback" is reset afterwards. The other exception is nlprompt(), but this function is only used within readtoken1() (but in contexts where no nested calls to xxreadtoken() occur) and xxreadtoken() (where "tokpushback" is guaranteed to be zero). function old new delta parseheredoc 124 131 +7 Signed-off-by: Christoph Schulz <develop@kristov.de> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>
