* Skip the git-rev in the hash for now (from a5e8d632)Josh Stone2009-03-261-1/+4
| | | | | | It may be potentially expensive to fork-exec a git call to get the HEAD revision, and it's not clear whether it's even needed. We can always throw this back on if we find a meaningful usage scenario.
* PR10001: Use the kernel's strlcpy & strlcatJosh Stone2009-03-261-16/+5
| | | | | | We had our own implementations of these which were triggering gcc bug38480 in some particular cases. It's easier for us to use the kernel's strlcpy and strlcat anyway, which avoids the bug.

* Add the kernel tree's git revision to the hashJosh Stone2009-03-253-0/+32
| | | | | To better support kernel developers who work out of a single source tree, this adds the git HEAD revision to our caching hash.
* Add more file stats to the hashJosh Stone2009-03-252-14/+25
| | | | | | | | | | For kernel developers, it may be common practice to reuse the same kernel build tree for several kernel variants. Our previous hashing only considered the release version, architecture, and build path, which may all remain constant for such a developer. This change adds the file size and mtime of several kernel version files to the hash, so it should be a bit more robust against collisions.

| | | | | | | | | | | | | | | | | | | | This fix caused a regression on fedora. stap -ve 'probe process("/bin/ls").function("main") { log(pp()); } probe process("/lib64/libc.so.6").function("*") { log(pp()); }' \ -c /bin/ls hung (with stapio & ls processes spinning) upon startup.

* Cache the tracepoint query resultsJosh Stone2009-03-204-1/+53
| | | | | | | To use tracepoints, we build a "tracequery" module that compiles debuginfo for all available tracepoints in the user's kernel. That's a bit of a cumbersome step to do during pass-2 though. This change adds tracequery caching so we only need to compile it once.
