2018-01-24Make 2.3.0 releasev2.3.0Ulf Magnusson
Just adds a new warning: 0087b40 ("Warn if a symbol with unsatisfied deps is selected")
2018-01-24Warn if a symbol with unsatisfied deps is selectedUlf Magnusson
Mirrors a warning in the C implementation. Make it a bit more informative and simpler to decode for people who aren't super familiar with Kconfig. The warning is printed when/if the symbol is evaluated, e.g. when writing a .config or C header or accessing Symbol.str/tri_value. It is not printed if the symbol value has already been calculated and is cached and up-to-date, which avoids warning spam. Example: config Y_SYMBOL_1 def_bool y config Y_SYMBOL_2 def_bool y config SELECTED bool depends on !Y_SYMBOL_1 config SELECTING_1 def_bool y select SELECTED # Skipped in warning, because n config SELECTING_2 def_bool n select SELECTED config SELECTING_3 def_bool y select SELECTED if Y_SYMBOL_1 depends on Y_SYMBOL_2 # Defined in multiple locations config SELECTING_3 Generated warning: warning: SELECTED (defined at Kconfig:7) has unsatisfied direct dependencies (!Y_SYMBOL_1), but is currently being selected by the following symbols: SELECTING_3 (value: y, defined at Kconfig:20, Kconfig:26), with direct dependencies "y" (value: y) and select condition Y_SYMBOL_1 && Y_SYMBOL_2 (value: y) SELECTING_1 (value: y, defined at Kconfig:11), with direct dependencies "y" (value: y) Real-world example from test suite: warning: NOT_COHERENT_CACHE (defined at arch/powerpc/platforms/Kconfig.cputype:381) has unsatisfied direct dependencies (4xx || PPC_8xx || E200 || PPC_MPC512x || GAMECUBE_COMMON), but is currently being selected by the following symbols: AMIGAONE (value: y, defined at arch/powerpc/platforms/amigaone/Kconfig:2), with direct dependencies 6xx && BROKEN_ON_SMP (value: y) and select condition 6xx && BROKEN_ON_SMP (value: y)
2018-01-23Mention loading of multiple .config filesUlf Magnusson
2018-01-22Make 2.2.4 releasev2.2.4Ulf Magnusson
Small docstring improvements: - 1c37079 ("Add more detail to the write_config() docstring") - 121d4a7 ("Add more detail to the write_autoconf() docstring") - 27fbded ("Fix outdated comments referencing user_str/tri_value") - e01cb49 ("Mention user_value in the load_config() docstring") - ed32010 ("Add some more detail to the module docstring") Code nit: - 532b561 ("Simplify escape()")
2018-01-22Add some more detail to the module docstringUlf Magnusson
Clarify how to fetch help texts and prompts, mention the no-prompt warning.
2018-01-22Simplify escape()Ulf Magnusson
The fancy regex isn't really justified. Much faster with replace() too, though this is an unlikely hotspot. Could have used a \g<0> backreference to refer to the entire match instead of using a capturing group too. Hadn't discovered that. Add some selftests for escape() and unescape() too.
2018-01-22Mention user_value in the load_config() docstringUlf Magnusson
Can be handy to check which symbols got set, like merge_config.py does.
2018-01-22Fix outdated comments referencing user_str/tri_valueUlf Magnusson
Ended up with just user_value in the end before releasing Kconfiglib 2.
2018-01-22Add more detail to the write_autoconf() docstringUlf Magnusson
Same order as for .config files.
2018-01-22Add more detail to the write_config() docstringUlf Magnusson
Can be handy to know that the order of the assignments matches the Kconfig files.
2018-01-21Whitespace nitsUlf Magnusson
2018-01-21Linkify test suiteUlf Magnusson
2018-01-20Make 2.2.3 releasev2.2.3Ulf Magnusson
Parsing performance improvements related to help texts: - c800f70 ("Simplify _deindent()") - 707204a ("Get rid of _next_help_line()") - f0a87cc ("Micro-optimize _T_HELP parsing") Also includes various code nits. Brings 'make scriptconfig' with allyesconfig.py down to 1.3 seconds, including the 'make' overhead.
2018-01-20Getting fasterUlf Magnusson
2018-01-20Micro-optimize _T_HELP parsingUlf Magnusson
Shaves a few % more from _parse_properties().
2018-01-20Get rid of _next_help_line()Ulf Magnusson
Speeds things up a bit further. Rework the unget handling to save the ungotten line directly instead of using a flag. Add some help texts to tests/Klocation to make sure the line number is updated properly for those.
2018-01-19Simplify loop in _T_HELPUlf Magnusson
Bit easier to read.
2018-01-19Always rstrip() when dedentingUlf Magnusson
Factors out some code and makes the logic a bit more transparent. It's only used for help text lines.
2018-01-19Rearrange _T_HELP codeUlf Magnusson
Bit clearer.
2018-01-19Simplify _deindent()Ulf Magnusson
Old code. Can't remember why it kept lines shorter than the indent as-is instead of clearing them, but it's pointless for help texts, which is the only place where _deindent() is used. s[n:] is safe even if n >= len(s). Help text parsing is pretty hot code too, so every bit helps.
2018-01-18Mention how invalidation is avoided for constant symbolsUlf Magnusson
2018-01-18Make 2.2.2 releasev2.2.2Ulf Magnusson
- 97c7501 ("Fix 'source "missing"' error message for Python 3") makes the hint re. environment variables display properly for Python 3 when a sourced file can't be opened. - 8574dc5 ("Make PyPI's README formatter happy") makes PyPI format the README properly.
2018-01-18Fix 'source "missing"' error message for Python 3Ulf Magnusson
IOError() generates an OSError in Python 3.6. OSError does not have a 'message' attribute, which caused the following error when trying to add the hint re. environment variables (the rest of the message was still displayed): AttributeError: 'OSError' object has no attribute 'message' Use str(exception) instead, which seems to work for both Python 2 and Python 3.
2018-01-18Make PyPI's README formatter happyUlf Magnusson
No longer displayed as an unformatted blob of text.
2018-01-18Make 2.2.1 releasev2.2.1Ulf Magnusson
- 7dc5b74 ("Detect recursive 'source' and print backtrace") makes debugging recursive 'source's a bit easier. - Various minor code nits.
2018-01-18Use absolute link for kconfiglib-2-changes.txtUlf Magnusson
Try to unbreak PyPI display.
2018-01-18Use absolute links in READMEUlf Magnusson
See if this unbreaks the display on PyPI.
2018-01-18Clarify when symbols get the default n valueUlf Magnusson
"Active user value" might have been a bit unclear. The symbol needs to be visible.
2018-01-18Rearrange _T_(MENU)CONFIG parsing codeUlf Magnusson
Bit neater.
2018-01-17Fix some typosUlf Magnusson
2018-01-17Improve recursive 'source' testUlf Magnusson
Check for incorrect exceptions instead of propagating them, and get rid of the flag.
2018-01-17Detect recursive 'source' and print backtraceUlf Magnusson
Easier to debug than a RecursionError. Point out in the exception message that a common cause is environment variables not being set correctly.
2018-01-16Move _rec_invalidate_if_has_prompt() to after _rec_invalidate()Ulf Magnusson
2018-01-16Roll invalidation logic into _is_user_assignable()Ulf Magnusson
And rename it to _rec_invalidate_if_has_prompt(). Always used in this way in practice.
2018-01-16Make 2.2.0 releasev2.2.0Ulf Magnusson
- 94c63de ("Support disabling warnings for redundant assignments") adds support for disabling warnings in the case where a symbol is assigned more than once within a .config file but always assigned the same value. Contributed by Sebastian Bøe. - Various other minor code nits.
2018-01-16_tokenize() non-constant symbol parsing style nitUlf Magnusson
Saves a tiny bit of bytecode too.
2018-01-16Kconfiglib is easier to modify tooUlf Magnusson
2018-01-16Fix lying implementation commentsUlf Magnusson
Implicit submenus are created after parsing, in _finalize_tree(), so the parent can never be a symbol in _parse_block().
2018-01-16Get TRI_TO_STR from Kconfiglib in test suiteUlf Magnusson
Old code.
2018-01-16Reset _tokens_i just once in _tokenize()Ulf Magnusson
It's set to -1 in every return path, so we can just do it at the beginning instead.
2018-01-16Update copyright year in licenseUlf Magnusson
2018-01-16Do not optimize promptless choice symbolsUlf Magnusson
Choice symbols without prompts are pointless and probably nonexistent in practice, so it's a bit silly to run the no-prompt optimization for them. Piggyback copyright year update.
2018-01-15Use a neater style when returning cached valuesUlf Magnusson
Saves a tiny bit of bytecode too.
2018-01-15Simplify non-bool/tristate return in tri_value()Ulf Magnusson
Already know the value.
2018-01-15Remove redundant backslashUlf Magnusson
2018-01-15Get rid of 'keyword' assignment in _tokenize()Ulf Magnusson
Also switch to a faster local lookup for the second _T_HELP. Micro-optimization -- shaves a % or two of the _tokenize() runtime. We expect a token for valid Kconfig files, so the naming is still fine.
2018-01-15Merge pull request #36 from SebastianBoe/support_disabling_redundant_warningsUlf Magnusson
Support disabling warnings for redundant assignments
2018-01-15Support disabling warnings for redundant assignmentsSebastian Bøe
The Linux Kernel's merge_config.sh defaults to disabling warnings for redundant assignments and has support for enabling them specifically. This patch reproduces this behaviour in kconfiglib except that we retaing kconfiglib's default behaviour of enabling the warnings. Signed-off-by: Sebastian Bøe <sebastian.boe@nordicsemi.no>
2018-01-12Add an extra test suite Makefile patch warningUlf Magnusson
2018-01-11Mention that $CONFIG_ is used for C headers tooUlf Magnusson
Piggyback some cleanup and redundant comment removal.
