From 859093dae7dcadaff2e15a3885a1824b0d5f5913 Mon Sep 17 00:00:00 2001 From: David Kalnischkies Date: Sat, 30 Aug 2014 11:29:45 +0200 Subject: [PATCH] support regular expressions in 'apt search' apt-cache search supported this since ever and in the code for apt was a fixme indicating this should be added here as well, so here we go. --- apt-private/private-cmndline.cc | 9 +++-- apt-private/private-search.cc | 52 +++++++++++++++++++--------- test/integration/framework | 8 ++++- test/integration/test-apt-cli-search | 15 ++++++++ 4 files changed, 64 insertions(+), 20 deletions(-) diff --git a/apt-private/private-cmndline.cc b/apt-private/private-cmndline.cc index a21a9dc8c..a4490f5b4 100644 --- a/apt-private/private-cmndline.cc +++ b/apt-private/private-cmndline.cc @@ -70,6 +70,8 @@ static bool addArgumentsAPTCache(std::vector &Args, char cons else return false; + bool const found_something = Args.empty() == false; + // FIXME: move to the correct command(s) addArg('g', "generate", "APT::Cache::Generate", 0); addArg('t', "target-release", "APT::Default-Release", CommandLine::HasArg); @@ -77,7 +79,8 @@ static bool addArgumentsAPTCache(std::vector &Args, char cons addArg('p', "pkg-cache", "Dir::Cache::pkgcache", CommandLine::HasArg); addArg('s', "src-cache", "Dir::Cache::srcpkgcache", CommandLine::HasArg); - return true; + + return found_something; } /*}}}*/ static bool addArgumentsAPTCDROM(std::vector &Args, char const * const Cmd)/*{{{*/ @@ -172,6 +175,8 @@ static bool addArgumentsAPTGet(std::vector &Args, char const addArg('s', "no-act", "APT::Get::Simulate", 0); } + bool const found_something = Args.empty() == false; + // FIXME: move to the correct command(s) addArg('d',"download-only","APT::Get::Download-Only",0); addArg('y',"yes","APT::Get::Assume-Yes",0); @@ -197,7 +202,7 @@ static bool addArgumentsAPTGet(std::vector &Args, char const addArg(0,"install-suggests","APT::Install-Suggests",CommandLine::Boolean); addArg(0,"fix-policy","APT::Get::Fix-Policy-Broken",0); - return true; + return found_something; } /*}}}*/ static bool addArgumentsAPTMark(std::vector &Args, char const * const Cmd)/*{{{*/ diff --git a/apt-private/private-search.cc b/apt-private/private-search.cc index ecd5d7fad..2230c973a 100644 --- a/apt-private/private-search.cc +++ b/apt-private/private-search.cc @@ -36,8 +36,28 @@ bool FullTextSearch(CommandLine &CmdL) /*{{{*/ if (unlikely(Cache == NULL || Plcy == NULL)) return false; - const char **patterns; - patterns = CmdL.FileList + 1; + // Make sure there is at least one argument + unsigned int const NumPatterns = CmdL.FileSize() -1; + if (NumPatterns < 1) + return _error->Error(_("You must give at least one search pattern")); + +#define APT_FREE_PATTERNS() for (std::vector::iterator P = Patterns.begin(); \ + P != Patterns.end(); ++P) { regfree(&(*P)); } + + // Compile the regex pattern + std::vector Patterns; + for (unsigned int I = 0; I != NumPatterns; ++I) + { + regex_t pattern; + if (regcomp(&pattern, CmdL.FileList[I + 1], REG_EXTENDED | REG_ICASE | REG_NOSUB) != 0) + { + APT_FREE_PATTERNS(); + return _error->Error("Regex compilation error"); + } + Patterns.push_back(pattern); + } + + bool const NamesOnly = _config->FindB("APT::Cache::NamesOnly", false); std::map output_map; std::map::const_iterator K; @@ -56,26 +76,23 @@ bool FullTextSearch(CommandLine &CmdL) /*{{{*/ if (Done%500 == 0) progress.Progress(Done); ++Done; - - int i; + pkgCache::DescIterator Desc = V.TranslatedDescription(); pkgRecords::Parser &parser = records.Lookup(Desc.FileList()); - + bool all_found = true; - for(i=0; patterns[i] != NULL; ++i) + for (std::vector::const_iterator pattern = Patterns.begin(); + pattern != Patterns.end(); ++pattern) { - // FIXME: use regexp instead of simple find() - const char *pattern = patterns[i]; - all_found &= ( - strstr(V.ParentPkg().Name(), pattern) != NULL || - strcasestr(parser.ShortDesc().c_str(), pattern) != NULL || - strcasestr(parser.LongDesc().c_str(), pattern) != NULL); - // search patterns are AND by default so we can skip looking further - // on the first mismatch - if(all_found == false) - break; + if (regexec(&(*pattern), V.ParentPkg().Name(), 0, 0, 0) == 0) + continue; + else if (NamesOnly == false && regexec(&(*pattern), parser.LongDesc().c_str(), 0, 0, 0) == 0) + continue; + // search patterns are AND, so one failing fails all + all_found = false; + break; } - if (all_found) + if (all_found == true) { std::stringstream outs; ListSingleVersion(CacheFile, records, V, outs); @@ -83,6 +100,7 @@ bool FullTextSearch(CommandLine &CmdL) /*{{{*/ V.ParentPkg().Name(), outs.str())); } } + APT_FREE_PATTERNS(); progress.Done(); // FIXME: SORT!
