The way that was achieved was by getting rid of the obscure and not well used functions sqlSafefFrag and sqlDyStringPrintfFrag and replacing them with the plain versions of those functions, since these are not needed anymore. The new version checks for NOSQLINJ in unquoted %-s which is used to include SQL clauses, and will give an error the NOSQLINJ clause is not present, and this will automatically require the correct behavior by developers. sqlDyStringPrint is a very useful function, however because it was not enforced, users could use various other dyString functions and they operated without any awareness or checking for SQL correct use. Now those dyString functions are prohibited and it will produce an error if you try to use a dyString function on a SQL string, which is simply detected by the presence of the NOSQLINJ prefix. diff --git src/hg/hgc/mafClick.c src/hg/hgc/mafClick.c index 2701de0..f7a35fa 100644 --- src/hg/hgc/mafClick.c +++ src/hg/hgc/mafClick.c @@ -1,845 +1,845 @@ /* Handle details pages for maf tracks and axt tracks. */ /* Copyright (C) 2013 The Regents of the University of California * See kent/LICENSE or http://genome.ucsc.edu/license/ for licensing information. */ #include "common.h" #include "hash.h" #include "linefile.h" #include "hgc.h" #include "maf.h" #include "obscure.h" #include "cheapcgi.h" #include "genePred.h" #include "botDelay.h" #include "hgMaf.h" #include "hui.h" #include "hCommon.h" #include "hubConnect.h" #include "trackHub.h" #include "chromAlias.h" extern boolean issueBotWarning; #define ADDEXONCAPITAL /* Javascript to help make a selection from a drop-down * go back to the server. */ static char *autoSubmit = "document.gpForm.submit();"; static void blueCapWrite(FILE *f, char *s, int size, char *r) /* Write capital letters in blue. */ { boolean isBlue = FALSE; int i; for (i=0; i<size; ++i) { if (r!=NULL && s[i]==r[i]) fprintf(f, "."); else { char c = s[i]; if (isupper(c)) { if (!isBlue) { fprintf(f, "<span style='color:#0000FF;'>"); isBlue = TRUE; } } else if (islower(c)) { if (isBlue) { fprintf(f, "</span>"); isBlue = FALSE; } } fprintf(f, "%c", c); } } if (isBlue) fprintf(f, "</span>"); } void initSummaryLine(char *summaryLine, int size, int val) /* Fill summary line with stars and null terminate */ { int i; for (i = 0; i < size; i++) summaryLine[i] = val; summaryLine[i] = 0; } void updateSummaryLine(char *summaryLine, char *referenceText, char *alignText, int size) /* Blank out columns in the summary line where this alignment * differs from the reference */ { int i; for (i=0; i<size; i++) { if (alignText[i] != referenceText[i]) summaryLine[i] = ' '; } } void mafPrettyOut(FILE *f, struct mafAli *maf, int lineSize, boolean onlyDiff, int blockNo, struct hash *labelHash) { int ii, ch; int srcChars = 0; struct mafComp *mc; int lineStart, lineEnd; char *summaryLine = needMem(lineSize+1); char *referenceText; int startChars, sizeChars, srcSizeChars; boolean haveInserts = FALSE; struct mafComp *masterMc = maf->components; startChars = sizeChars = srcSizeChars = 0; for (mc = maf->components; mc != NULL; mc = mc->next) { /* Figure out length of source (species) field. */ /*if (mc->size != 0)*/ { char dbOnly[128]; int len; char *org; memset(dbOnly, 0, sizeof(dbOnly)); safef(dbOnly, sizeof(dbOnly), "%s", mc->src); chopPrefix(dbOnly); if ((org = hOrganism(dbOnly)) == NULL) len = strlen(dbOnly); else len = strlen(org); if (srcChars < len) srcChars = len; len = digitsBaseTen(mc->start); if (startChars < len) startChars = len; len = digitsBaseTen(mc->size); if (sizeChars < len) sizeChars = len; len = digitsBaseTen(mc->srcSize); if (srcSizeChars < len) srcSizeChars = len; if (mc->text && (mc->rightStatus == MAF_INSERT_STATUS) && (masterMc->start + masterMc->size < winEnd)) haveInserts = TRUE; #ifdef REVERSESTRAND /* complement bases if hgTracks is on reverse strand */ if (mc->size && cartCgiUsualBoolean(cart, COMPLEMENT_BASES_VAR, FALSE)) complement(mc->text, maf->textSize); #endif } } /* first sequence in the alignment */ referenceText = maf->components->text; for (lineStart = 0; lineStart < maf->textSize; lineStart = lineEnd) { int size; lineEnd = lineStart + lineSize; if (lineEnd >= maf->textSize) lineEnd = maf->textSize; size = lineEnd - lineStart; initSummaryLine(summaryLine, size, '*'); for (mc = maf->components; mc != NULL; mc = mc->next) { char dbOnly[128], *chrom; int s = mc->start; int e = s + mc->size; char *org; char *revComp = ""; char strand = mc->strand; - struct dyString *dy = newDyString(512); + struct dyString *dy = dyStringNew(512); #ifdef REVERSESTRAND if (cartCgiUsualBoolean(cart, COMPLEMENT_BASES_VAR, FALSE)) strand = (strand == '+') ?
