From 72e11ec4a1b3cd663e803ef28540870efcad0a92 Mon Sep 17 00:00:00 2001 From: Ezra Peisach Date: Thu, 27 Jun 1996 14:38:14 +0000 Subject: [PATCH] * asn1buf.c (asn12krb5_buf): Initialize magic fields of structure. (asn1buf_expand): If pre-allocating memory for future use, store proper end of buffer. This was a big performance hit in asn.1 routines as every time it tried to decode an octet, 200 bytes were allocated (for future use), but the buffer structure pnly thought that one byte was allocated and the next time through would try to allocate memory again. git-svn-id: svn://anonsvn.mit.edu/krb5/trunk@8553 dc483132-0cff-0310-8789-dd5450dbe970 --- src/lib/krb5/asn.1/ChangeLog | 6 ++++++ src/lib/krb5/asn.1/asn1buf.c | 4 +++- 2 files changed, 9 insertions(+), 1 deletion(-) diff --git a/src/lib/krb5/asn.1/ChangeLog b/src/lib/krb5/asn.1/ChangeLog index 377351ad1..fe9fe3709 100644 --- a/src/lib/krb5/asn.1/ChangeLog +++ b/src/lib/krb5/asn.1/ChangeLog @@ -1,3 +1,9 @@ +Thu Jun 27 10:31:34 1996 Ezra Peisach + + * asn1buf.c (asn12krb5_buf): Initialize magic fields of structure. + (asn1buf_expand): If pre-allocating memory for future use, store + proper end of buffer. + Wed Jun 12 14:25:11 1996 Theodore Ts'o * asn1_k_encode.h, asn1_k_decode.h: Add prototypes for the SAM diff --git a/src/lib/krb5/asn.1/asn1buf.c b/src/lib/krb5/asn.1/asn1buf.c index 327a9dfd5..822b26377 100644 --- a/src/lib/krb5/asn.1/asn1buf.c +++ b/src/lib/krb5/asn.1/asn1buf.c @@ -226,6 +226,7 @@ asn1_error_code asn12krb5_buf(buf, code) int i; *code = (krb5_data*)calloc(1,sizeof(krb5_data)); if(*code == NULL) return ENOMEM; + (*code)->magic = KV5M_DATA; (*code)->data = NULL; (*code)->length = 0; (*code)->length = asn1buf_len(buf); @@ -350,7 +351,8 @@ asn1_error_code asn1buf_expand(buf, inc) inc : STANDARD_INCREMENT)) * sizeof(asn1_octet)); if(buf->base == NULL) return ENOMEM; - buf->bound = (buf->base) + bound_offset + inc; + buf->bound = (buf->base) + bound_offset + (inc > STANDARD_INCREMENT ? + inc : STANDARD_INCREMENT); buf->next = (buf->base) + next_offset; return 0; } -- 2.26.2
